Introduction
The Company specializes in producing magnetic metal detectors and clothing machinery and
instruments.
The magnetic metal detectors include: the series of LX-630A and so on. The last designed series
of LX-630A feature the streamlined outward appearance. A nine-set of magnetic sensitive sensor
detection is installed in a range of width of 600mm, which strengthens the detection effect and
enhances the reliability. On the operating board of the instrument is installed the display of the
detection location for inspecting the location, which can reveal precisely the specific location of
the object being detected, the display of the level of sensitiveness, the volume of adjustment of the
sensitiveness detection capacity that is required to reveal working status of the instrument, and the
dynamic display of sensitiveness on the ten sensors. The instrument is equipped with a new
counter and an infrared photoelectric control system. The major control board of the system
adopts the most advanced installation technique of electric chips in the world, which results in
high reliability and simple periphery circuit. The system is equipped with advanced switch power
supply with good anti-interference feature. The voltage ranges within AC85-264V, which only
requires an electric motor with appropriate voltage. With the advanced facilities mentioned above,
the system features sensitive anti-interference, easy manipulation, speedy detection, complete
functions, stable quality, and reasonable price. It can be applied to production lines with
consecutive automatic operation as well as man-made automatic detection. The scope of
application of it includes: foods, fruits, aquatic products, pharmaceuticals, clothing, knit goods,
down quilts and eider down outerwear, toys, bedding, carpets and mat materials, buttons and
zippers, chemical products, and industrial materials to detect impurity substances such as draw
points, and ferromagnetic materials, etc. Because of the difference of operating principles, the
system is unable to detect non-ferromagnetic materials such as fine copper and pure aluminum.
The Company holds the patent right for its products with ZL94227712.0 as its patent license.
Actions will be taken against any imitation of the patent technology.

1. Voltage of the Power:AC100V-240V (single phase); 50-60HZ±10%. The machine will be
supplied withAC220V, 50HZ as its standard if there is no special appointment while placing
an order of it.
2. Power: <140W;
3. Width of the Detection Pass: 600mm;
4. Speed of Conveyer Belt: 32m/min. (50HZ), 40m/min. (60HZ);
5. Adjustment of the Level of Induction: Consecutive adjustment from level 1 to 10;
6. DetectionApproach: Magnetic induction;
7. Warning Pattern: Tingle of an electronic buzzer, pause or reverse of the conveyer belt, and the
indication of the electro-luminescent lamp.
Explanations of the Parts:
1. The control board of the power source:
a) The plug: while a plug receptacle with a good earth wire is plugged in, it is always
required to adapt the voltage of the electric motor to the power source.
b) The power: the red indicator lamp lights when the switch is on;
c) The level: the level of induction increases when the adjustment goes up;
d) The AHEAD-BACK: a switch indicates the working status of the electric machine. When
it is atAHEAD, the conveyer belt goes forward and stops after warning. When it is at
BACK, it reverse after warning;
e) The light: infrared opto-electronic switch. When it adapts “On”and the object to be
detected can keep off the infrared beam reliably, the instrument detects the circuit. If the
object to be detected is lower than 15mm, or if it is translucent, has a light leak and hence
cannot keep off the infrared beam reliably, the switch should be put on “OFF”. The
detecting circuit of the instrument maintains its working condition. Outward interference
towards the instrument should be avoided.
2. The operational board:
a) The counter: six-digit display. The principle of the operation is that if the object to be
detected can keep off the infrared beam reliably for one time, the counter accumulative
totals one. If the object to be detected is lower than 15mm, or if it is translucent and has
light leap, the counter cannot work normally. It counts if the product is up to standard. It
does not count if the product is not up to standard. There is a lithium battery in the
counter, which lasts 10 years in 25°C. The “0”button indicates erase. The “LOCK”
may prevent people from pressing the button wrong. The button “ON”, which indicates
the working condition, is on the right. The “OFF”disconnects the counter.
b) The DETECT 10N: the detection status 10 is a display window that is corresponding to
the ten horizontal sensors for the pass of detection. When the electro-luminescent
lamplights, it indicates that a foreign matter exists in a location it is passing. If the
margin of the display lights consistently, it indicates that there exists outward

- 3 -
interference. If it lights periodically in a certain location, it indicates that there exist
pollutants in the corresponding location on the conveyer belt. Interference should be
eliminated. The conveyer belt should be cleaned.
c) The level: there sets up a display of the level of induction for the instrument. The more
the light pillars are，the higher the level of the induction of the instrument is.
d) The monitor: the dynamic induction of the instrument indicates that the more of the light
pillars are, the higher intensity the instrument affected from ferromagnetic materials.
When it is in operation, it reflects the size of the mass of the ferromagnetic materials and
the relevant distance of the detective sensor. If it is not working while the light pillars
lights repeatedly, it is advised that we examine whether there exists outward interference,
such as high-tension wires, power transformers, electro motors, and mechanical facilities,
or whether there is wobble and pollution on the conveyer belts.
e) The start: the button is start or pause.
Auto-Conveyance Magnetic Induction Metal Detector LX-630A
1. Operation Instruction:
a) To connect with the alternating current power supply that has a earth wire with
appropriate voltage required by the instrument;
b) To press “POWER”(the red button on the electric board) and the “START”(on the board
of operation), the conveyer belt will start operation. The detection can then begin. The
conveyer belt will stop if the “START”is pressed again.
c) There installed a display of the level of detection induction and a display of the detection
location on the operation control panel where there are an automatic warning device and
a counter. The instrument will alarm automatically if it detects draw points or iron
containing metals. The indicator lamp will display the location of the detection and the
conveyer belt will stop operation. Products that are not up to the standard will be
returned to the operators while those that are up to the standard will pass the detection
and count. Those that are not up to the standard will not be counted.
2. Points for Attention:
a) Please test-detect the sample draw points, iron fragments, or the attached parts for
detection by the instrument. Make sure that the instrument works normally only if it
alarms and the conveyer belt stops in the process of trial detection.
b) The materials that could be detected through the instrument are ironwork and
iron-containing materials. Non-ferromagnetic materials such as pure aluminum, copper,
etc are unable to be detected.
c) The instrument is reactive to movable metal materials. Operators are required not to
carry any of them in the process of operation.
How to Use
Points for Attention

- 4 -
1) To connect the power line
with appropriate power
source;
The power line to be used should be insert in the plug
receptacle that carries with an earth wire. If it shares a
plug receptacle with other electric machines, it might
cause interference and is easy to make wrong warnings.
2) To press the button of
power supply;
The red lamp will light when the instrument is set up an
electric circuit.
3) To press the buttons of
Operation or Pause;
The button controls the live wire. When the power is on,
the conveyer belt will be in operation.
4) How to adjust the
conveyer belt.
If the conveyer belt is deviated, please adjust it with the
die nut attached.
3. Features:
a) The automatic conveyance magnetic induction metal detector LX-630A can detect the
varia of steel and iron easily and reliably. The signaler prompts that the ferromagnetic
varia has been detected.
b) The warning device makes sounds when the instrument detects draw points or iron
containing materials. At that time, the conveyer belt will pause and the indicator lamp
will display the location of the iron containing materials among the objects being
detected and return the disqualified products. Efficiency will then be improved greatly.
c) The instrument is equipped with a counter, which accumulative totals the number of the
qualified products.
d) The adjustment of the sensibility of the operation of the automatic conveyance magnetic
induction metal detector LX-630A is in accordance with the size and types of the objects
to be detected, which makes it possible to find the ferromagnetic varia and draw points
among the products easily.
e) It improves the capability and reliability of detection greatly due to the adoption of the
latest-designed detection device.
4. Uses:
a) The various needle detection devices of the automatic conveyance magnetic induction
metal detector LX-630A may detect the needles, broken needles, and other iron
fragments that are hidden in all kinds of sewing products, such as man’s clothing,
woman’s clothing, child’s clothing, underwear, kimono, jackets, beddings, shoes, caps,
gloves, plush toys carpets, and hygienic products. They can also be used in detecting the
pharmaceuticals, the foodstuff, including fresh edible fungi, fish, meals, fruits, and their
products. The detection of the zippers and buttons for clothing is also possible. It is also
possible to detect the iron fragments mixed within the non-ferromagnetic materials such
as copper, aluminum, zinc, papermaking, robber, and raw industrial chemicals.
b) When the fittings of sewing products such as the zippers, the buttons, and the hooks are
being detected, it is always suggested to consider the non-ferromagnetic merchandise
such as those that have been demagnetized.
c) When the automatic conveyance magnetic induction metal detector LX-630A is being
used, operators are required to take off the iron containing objects from their clothes as
the instrument is reactive to all the iron containing objects and produce alarm wrongly.
5. Points of Attention for Installation:

- 5 -
a) Before it is put into use, the instrument should be put in a horizontal place where there is
no vibration. It is expected to adjust the four boy-bolts until they support the instrument
stably and the four direction wheels disconnected with the ground. When the instrument
is in a horizontal position, fix the fastening bolts until they do not vibrate. Otherwise, the
conveyer belt will sway.
b) The instrument is not allowed to install on an operating platform made of iron or beside
an iron frame.
c) The instrument is not allowed to install beside a machine that will cause magnetic field
as it will cause electricity and interference of magnetic field, which may result in wrong
operation of the instrument. These machines include: motor-driven clutch motors, sewing
machines, tailoring machines, balers, air-conditioners, high-tension bus-bar ceiling fans,
and machines that have rotating mechanism.
d) The instrument should be installed in a place far away from huge movable iron objects,
such as trains, motor vehicles, etc.
e) The instrument should be far away from materials made of steel and iron, such as iron
doors, iron windows. The direction of the major parts of the instrument could be adjusted
so as to change the location of the instrument to avoid wrong operation.
f) The instrument will cause a magnetic field. Operators should pay attention to the credit
cards, cards of drawing, telephone cards with them, and telephones around, etc that
might be affected by the magnetic field of the instrument.
g) The instrument should be installed in a temperature surrounding from 0°C to 40°C , a
place that will never be lower that the frozen point.
h) There should not be any flowing dusts, ferrous powder, and abrasive grits in the place
that locates the instrument. The place should not be moist and dew forming as well.
6. The Adjustment and Installation of the Sensitiveness:
a) The level of adjustment should be adjusted to “6-8”for sensitiveness. The level of
adjustment should be adjusted to “9-10”in order to detect trivial needle tips and iron
fragments. At this stage, higher demand is raised against the interference of the
surrounding metals and for the cleanness of the belt by the instrument
b) Detection could not be made among the products until one has been sure that the packing
and the subsidiary materials such as paper bags, paperboards, nylon packing bags,
buttons, and zippers are inactive to the instrument.
c) If the conveyer belt pause only because of the subsidiary packing materials, one should
adjust the button of sensitiveness from level “8-10”to level “5-7”so as to ensure that the
belt will no longer pause only due to the subsidiary materials.
Note: If the button of sensitiveness is adjusted to level “4”or lower, it will be difficult to
detect trivial metal materials and needle tips.
d) If the conveyer belt remains pause even after the adjustment of the button of
sensitiveness, one should: complete the detection of the packing and the subsidiary
materials first before one finalizes the selection of the packing materials so as to make
sure the packing and the subsidiary materials will pass the instrument normally.
e) The power source should be switched off after the completion of the detection. The
power line should be extracted from the plug receptacle if the instrument will not be used

- 6 -
for a period of time.
7. The Operations of the Instrument:
a) To switch on the joint power supply on the electric board and press the button of
“START”for operation Please test-detect the sample draw points, iron fragments, or the
attached parts for detection by the instrument as test operation. Make sure that the
instrument works normally only if it alarms and the conveyer belt stops in the process of
trial detection.
b) The object to be detected should be put on the conveyer belt lightly if the instrument is
operating properly. If there is nothing wrong with the object being detected, it will pass
the detection instrument. The counter on the control board will switch from “0”to “1”,
indicating that 1 detected object is up to the standard.
c) The object to be detected should be put on the conveyer belt lightly if the instrument is
operating properly. The instrument will alarm automatically if broken needles and iron
nails, etc. are detected among the object. The object will hence be returned to the front of
the operator. The counter on the control board will not display anything. The disqualified
object should be taken away. Press the button of “START”again for the next operation.
d) The exact location of the iron fragments detected among the object should be found and
taken away. Repeat the detection to make sure there is no further fragments remain in it.
It might be possible that there are 2 to 3 iron nails and fragments among the object. The
repetition of the detection can ensure the safety.
e) There might be wrong judge due to outside interference when the instrument is in
operation for detection. So a reconfirmation is required for the product if there finds a
warning signal.
8. Points for Attention:
a) Check up on the conveyer belt frequently to make sure that there are no remains of the
broken needles, rust, iron fragments, trivial iron tips other metal fragments, and greasy
dirt there. Special attention should also be paid to the reverse side of the belt to see
whether it is clean or not. To ensure the cleanness of the belt, it is advised to use wet
towels, detergents, and scaling to clean the belt.
b) The sensing devise on the conveyer belt should be detected as it has strong magnetic
performance, which might be adhered to needles or other metal fragments. Rubberized
fabric or other methods are expected to use in order to clean the sensing device so as to
make an accurate judge during the next operation.
c) The instrument adopts the theory of electromotive force. It makes the detection of the
instrument possible that the iron materials will cause sensing when they are in motion in
the magnetic field arisen by the detection instrument. The sensitiveness of the vertical
motion of the trivial needle tips that are parallel with the motion direction of the
magnetic line force is larger than that of the horizontal one. There exists different sensing
of detection towards different directions of the needle tips.
