Three, ask: small membrane plate not on the membrane?

Answer: 1. The white roller installation shall not exceed the template, **** narrow 8mm;

2. Low pressure on the hammer;

3. The upper membrane hammer has an outward and inward sloping pressure;

4. Upward slope of membrane plate;

5. Pressure at cots should not be too high;

6. Too large feeding tension is not easy to film;

7. The tension of membrane coil is not good;

Q: When is the length of the bag?

Answer: 1. The dust of photoelectric head is more;

2. Photoelectric sensitivity is not enough;

3. The tracking power is not obvious;

4. Excessive sealing pressure;

5. There are dirty things on the glue stick;

6. The air pressure of the secondary drawing frame feeding floating roller is too high;

7. Excessive feeding tension;

8. Longitudinal sealing knife ironing cloth roll too tight;

9. The temperature of the horizontal sealing knife is too high;

10. Low air pressure at the front and middle cots;

11. Feeding and pressing are out of sync;

12. The distance between photoelectric and cutting tool is too long;

13. The time difference between waiting time and heat sealing time is too large;

14. High speed;

Five, ask: before cutting knife inclined?

Answer: 1. Membrane deflection; 2.

2. Guide comb is missing or not straight;

3. The knife strikes diagonally;

4. The knife hits the top;

5. The end of the bag with holes should come out first;

6. The diagonal of the bag is different;

Six, ask: cut knife place plug material?

Answer: 1. The guide comb is far from the cutting knife;

2. The cutting tool is adjusted too low;

3. The bag is wrinkled or warped;

4. Fast feeding;

5. Guide comb not straight or lack;

6. Lower cutter should be mounted on;

7. For a bag with a hole, the head of the hole should be out first, but the tail should be out first;

Seven, ask: back seal have bubble?

Answer: 1. The bottom plate is dirty;

2. Uneven sealing knife pressure or large four-angle pressure;

3. Off-center of bottom plate;

4. Bottom silicone rubber should not be too wide;

5. The sealing knife is not installed;

6. Low sealing pressure and high temperature;

7. Cinnamon rubber is not smooth or aging;

8. If there are bubbles during operation, the bottom plate can be lined with hot cloth or the sealing knife is less inclined or overlapped;

Eight, ask: rectifying deviation time is too long?

Answer: 1. The film roll is not installed to the middle position of the reel or is not inflated and deviates; 2.

2. Film winding in series;
