Problem

Possible Cause

Solution

Cutting position is deviated from the color marks

1. Color mark follow up is not used.
2. The film color mark is weak.
3. Film is slipping.

1. Change follow up method into “follow up cut” in the follow up method display of the human-machine interface.
2. Refer to the magic eye instruction manual attached to adjust the sensitivity of the magic eye.
3. Adjust the tension of the rubber roller or the degree of tightness of the brake.

The cutter cut on products

1. The push rod and the cutter are asynchronous.
2. The height of the cutter seat is improper.
3. Packing speed is too high.

1. Refer to section 4.6.4 about push finger position.
2. Adjust he height of the end-sealing parts, adjust the sealing knife meshing center to the half of the product height.
3. Decrease the packing speed.

Burnt crimples appear on the seal

1. Temperature is too high.
2. Speed is too low.
3. The thermal endurance of the film’s outer layer is poor.

1. Bring down the temperature.
2. Increase the speed.
3. Replace with better film.

Sealing is loose or missed

1. Temperature is too low.
2. Speed is too high.
3. The thermal endurance of the film’s inner layer is poor.

1. Increase the temperature.
2. Decrease the speed.
3. Replace with better film.

Thermostat does not control temperature

1. Heating element is damaged
2. Solid state relay is burnt.
3. Thermocouple is damaged.
4. Temperature control meter is damaged.

1. Replace the heating element.
2. Replace the solid state relay.
3. Replace the thermocouple.
4. Replace the thermostat.
