Analysis of common problems of paper bag machine
Q: Is the bag wrinkled when passing the middle rubber roller?
Paper bag machine Answer: 1. The cooling effect of the back seal is not good;
2. The pressure of the middle rubber roller is uneven;
3. The air pressure is too high;
4. Excessive dust on the middle rubber roller;
5. The temperature of the back seal is too high;
6. The air pressure of the feeding floating roller of the second-hand bag making machine is too high;
7. The installation of the diaphragm is inclined;
Paper bag machine 2. Q: At the front cutter rubber roller, does the film go in one direction?
Answer: 1. The pressure of the rubber roller is not uniform, and the advancing film moves toward the direction of high pressure;
2. The photoelectric frame is tilted to keep the front rubber roller horizontal;
3. The punching knife is not installed well, and it is easy to tilt;
4. The thickness of the two sides of the film is uneven;
5. The pressure of the horizontal sealing knife is not uniform, and the other side goes toward that side;
6. Oblique on the diaphragm;
7. The middle rubber roller is not parallel; 3. Q: Is there no film on the small film plate?
Answer: 1. The white roller installation should not exceed the template, preferably 8mm narrower;
2. The pressure on the hammer is small;
3. The upper hammer of the membrane is inclined outwards and inwards;
4. Oblique on the diaphragm;
5. The pressure at the rubber roller should not be too large;
6. Excessive feeding tension is not easy to apply film;
7. The tension of the film roll is not good;
Paper bag machine 4. Q: How long is the bag out?
Answer: 1. There is a lot of dust on the photoelectric head;
2. The photoelectric sensitivity is not enough;
3. Tracking electricity is not obvious;
4. Excessive pressure of sealing knife;
Paper bag machine 5. There are dirty things on the glue stick;
6. The air pressure of the feeding floating roller used is too high;
7. Unwinding tension is too large;
8. The longitudinal sealing knife is too tight;
9. The temperature of the horizontal sealing knife is too high.
10. Low air pressure at the front and middle rubber rollers;
11. Feeding and pressing are not synchronized;
12. The distance between photoelectric and cutter is too long;
13. The difference between the waiting time and the heat sealing time is too large;
