How to Maintain The Pallet Wrapping Machine and How to Repair Related Faults

Equipment Maintenance

Tray Wrapping Machine1

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.  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.
