System
There will be no further description about the maintenance; please talk to the
commissioning technicians for detailed method about the system.
5.2. Temperature control
This machine has two sets of temperature control systems, which control the
“mid-sealing temperature” and the “end-sealing temperature” respectively. The
temperature setting value for each set of temperature control system is determined
according to the packing speed, the thickness of the packing film, and the
environment temperature. The optimum temperature setting value should have a
result that there is no leakage and burnt crimple for both mid-sealing and end-sealing.
The operation method for thermostat is described in the thermostat instruction
manual
attached to the machine.
5.3. Color mark magic eye
Magic eye is required for products to which following up is needed. After the
packing film is installed, adjust the position of the magic eye; along the light beam
emitted from the magic eye with to the place where color marks pass by, as shown
in diagram 21.

Maintenance
6.1. Shift cleaning and maintenance
1) Before cleaning the machine, cut off the power supply to the machine so as to
ensure the safety of people and the machine.
2) Clean the working table and the surface of the machine with a clean and
moistened cloth.
3) Clean off the film scraps stuck to the feeding mechanism, mid-sealing
mechanism and the end-sealing mechanism with compressed air.
4) Clean off the film scraps stuck to the end-sealing knife with a steel wire brush.
6.2. Monthly check and maintenance
1) Add lubricating oil to the meshing gears of the drive system and the chains of
the chain wheel, a thin layer of lubricating oil is enough. It is not allowed to add
lubricating oil to the synchronous belt of the machine and the flat conveyer belt.
2) Add lubricating oil to the end-sealing bearing.
3) Check the tension of the drive chain and belt, retighten if necessary.
4) Check all the screws and nuts, if there is any for loose screw or nut, retighten it.
5) Check carbon deposit, clean if necessary.
6.3. Biannual check and maintenance
1) Check the wearing condition of the drive belt and the flat conveyer belt,
replace if necessary.
2) Check all the wearing parts, replace the worn parts in time.
3) Check the wearing condition of the drive parts, replace if necessary.
4) Check the electric wiring and tighten if necessary. Clean the dust from the
electric elements with compressed air.
