Shrink packaging machine operating procedures and precautions
December 08, 2022
1. Close the left power switch;
2. Close the side thermal switch and adjust the side thermal knob to about 4-5 gears;
3. Combine the upper and lower thermal switches and adjust the lower hot knob to about 4-5 gears;
4. Close the conveyor switch and adjust the conveyor knob to about 4-5 gears;
5, adjust the heating temperature (can be set at about 130 ° C);
6. After the above operation is completed, let the machine run for about 3 minutes and then close the hot air switch (the hot air switch can not be opened in the actual operation);
7. Put the items that have been fitted with the shrink film, and then shrink packaging;
8. In the actual situation, if there are too many wrinkles after shrinking, the conveying speed can be reduced or the heating temperature can be increased. Conversely, if the shrinkage phenomenon occurs, the temperature can be lowered;
9. After the packaging is finished, first turn off the three-stage heating switch, but the conveying motor and the hot air motor continue to run for about 10 minutes, and then cut off the entire power supply.
Attention should be paid to the operation of the heat shrink packaging machine:
1. The heat shrink packaging machine is a (220v/380v voltage) single-phase/three-phase four-wire system, in which the neutral wire must be connected to the machine, otherwise the machine cannot operate normally;
2, the machine has a stainless steel heating tube, installed on both sides, very bright red when heating;
3. Note that the temperature of the shrinkage chamber should be controlled below 230 °C (sixth gear). If it is operated at over temperature, the circuit will prematurely age and the life of electrical components will decrease.
4. When the shrinking machine is used for more than three months, the aging of the wire in the shrinkage room should be checked and replaced as appropriate.
The classification of shrink packaging machines is divided into drying tunnel shrinking machine, oven shrinking machine, frame shrinking machine, gun shrinking machine, heat shrinking machine, bagging packaging machine, shrink packaging machine, film packaging machine, heat according to the type of machine. Shrink packaging machine, heat shrink film packaging machine, automatic heat shrink packaging machine, etc.
