§6 Equipment Maintenance

1.       Keep the space between the inner chain and the outer one lubricated by daubing the H20-HJ40 chemical oil. Tense the chains to eliminate the wobble in the ascending-and-descending process of the film system.


2.       When the turntable slows or skids, open the cover of the generator, loosen the four connecting screws on the decelerating panel and adjust them to tense the screws clockwise till get the needed tension. Then switch those four screws tightly.


3.  The carriage up-down process, the driving of the turntable and the film system are motivated by the activator with worm wheel and worm. Please obey the following instructions in process:

a) Apply the lubricated oiled decelerator. The deepness of the oil should be the same as the full-gear height of the worm if the worm is below the worm wheel or beside it. If the worm is above the worm wheel, that deepness should be 1/3 of the height of the outer diameter of the worm.

b) It is recommended to use synthesized worm oil 200# (the viscosity is 320 when the temperature is 40oc)

c) That deepness should be half of the height of the oil mirror if there is one. The central distance a=63mm and it is suggested to add 400ml.

d) The oil should be renewed after a 7-14 days of maiden operation. After this, the oil should be renewed once annually.

e)The surrounding temperature should range from –40 to +40oc. The lubricating oil should be the one with low freezing point when the temperature is below 0oc.


4.     Load the goods stably and handle them slightly to avoid the distortion of the under-pan or the shortening of the life of the components.


5.     The height of the goods should not exceed the set one. Otherwise, the packing will be undermined.


6.     To ensure a normal operation, the electric cabinet should be closed tightly and the components and the joints of wiring should be cleaned and checked periodically.

§7 Put into Use

Pallet Wrapping Machine made in china6.jpg


1 . Manual Operation:


Lower the film system to the bottom, load goods on the turntable and put the film scroll on the scroll seat. Thread the film properly in accordance with the requirements (see film-threading methods §8-3) and then start the turntable generator to activate the turntable and the film will wrap the bottom part of the goods. When the wrap amount meets the requirement, press the carriage up button to lift the film system to the required location (photoelectrical height-measuring is effective) and press the carriage down button to lower the film system to the bottom. Repeating the above-mentioned process will complete the packing, press the stop button to halt after this. It is suggested that manual operation is mainly for the adjusting on the machine.

2. Automatic Operation:

Restore the machine in its initiative state, load goods, thread the film properly and set the top circle amount and the bottom circle amount, up-down times, ,then press the auto-start button, the whole process will be completed automatically. To enforce enwinding, press the auto-Start button during the ascending or descending in the auto-process. Auto-running is strongly recommended in this machine.


3. Brief Introduction to the Auto-Running

Press auto-start when the machine is in its initiation (see the auto-run of §5) and the rotating-plate begins to speed-up (performs constant running when reaches its max. speed). When the film outputs with the running of the turntable , the turntable begins to count and the film system begins to ascend when the number meet the set parameter on the bottom. Re-press the auto-start during the ascending process of the film system, the ascending will pause and the turntable will run and count the circle amount The film system continues its ascending process after the enforcement meet the set parameter. The film system ascends till the goods beyond the irradiation of the photoelectric switch. The times should be counted as 1 and the rotating-plate continues to run and count. The film system begins to descend when the machine meet the set roof circle amount and stops at the bottom. The times should be counted as 1 again and the machine begins to count the bottom circle amount. The ascending and descending process repeats till reaches the set parameter and then the packing is complete. The rotating-plate decelerates slowly and stops at the initial checking and measuring point.


§8 Performance of the Functions & Others


8-1Error in Counting


The counting begins when the film system reaches its highest location in the auto-process, if at this time the sensor and the testing point are not at the same place, usually the roof circle amount does not appear as a integer. To ensure that the error is no more than half a circle, the circle amount can be increased or decreased, depending on the specific situation. The counting on the bottom circle amount after a circulation occurs as the mentioned-above.


8-2Instructions to the Operation of the Photoelectric Switch (SICK)


8-2-1 It is suggested that the set parameter of the photoelectric switch should not be adjusted frequently under the usual circumstance, for that will cause mal-action of the machine or damage to the switch.

8-2-2 The photoelectric switch will be ineffective under the sun or the halogen light and if the goods are colored glass items, items with low reflection, items with large space between their components and transparent items. In this condition, the switch should be adjusted in accordance with the methods mentioned . If this method does not work, then use the spare location-limiting block (§8-5) and turn the button in the electric cabinet to OFF to screen the photoelectric switch. The effect of this method is the same as or even better than that of the height-measuring by the photoelectric switch. The above-mentioned button must be turned to ON if the automatic height-measuring method is adopted.


8-3Sketch Picture of the Operation on the Film: Please thread the film as guided below.

Diagram 2  Block-Streching


8-4Movable Location-limiting Block

As showed in Diagram 5, the location-limiting block, which moves freely along the location-limiting guiding-bar, is made of nylon block embedded with magnet. This block moves freely between the upper fixed location-limiting block and the lower one to meet the requirements of the client when the function of the height-measuring photoelectric switch is contained.

8-5-1 Capability Features of the LLDPE Stretching Film

The film brings backpressure to the being packed, thus protecting the latter. The backpressure of the film is produced by the stretching. The cohesion reduces skidding and causes a repeating effect, forming a dynamic coat.


0-40%    Min. memory

40-75%   Memory begins to react

75-100%  Medium backpressure

100-200% Backpressure that easily attains max. percentage

200-250% It is suggested to chose proper films and stretching equipment to attain max. stretching

250%+  Affected by the stress, the film begins to intensely loose

300%+  Memory damaged, the film only equals to plastic film


8-5-2 Pre-Stretch:

According to the capabilities of the stretching film listed in §8-6-1, only the pre-stretching proportion of the pre-stretcher is set at 1:2.5 can the pre-stretcher perform its best. The pre-stretching proportion of this packager is based on the above-mentioned and is in conformity with the requirements of film tension in §5 Operating Instructions to the Controlling Panel, according to the test conclusion. The result will be the best when it is wrapped above the goods. The spring amount in the width of the film is about 10%.


8-5-3 Block-Stretch

Generally the result of the block-stretching method does not match that of the pre-stretching, for the protraction of the film produced by the former method is counteracted by the width and thickness of the film. The requirements vary in accordance with the specific packing method. With a relatively strong single-layer restriction and a lower cohesion, the block-stretching method can enhance the part placement



§9 Safety in the Use

1.       Test on the voltage of the controlling panel of direct current generator and that of the meg-powder arrester or between the PLC inputting point and the ground wire is prohibited.

2.       Check and find whether there are less-crowdedness or fall-off in the joint between different components periodically during the normal performance of the machine. If any, restore them to their original.

3.       Moving or removing the fixed upper or lower location-limiting block is prohibited!

4.       The rotating-plate of the machine should run clockwise.
