Handling methods for common problems of vertical packaging machine

1、 When the typing is not clear and there is no typing and production date
1. Check whether the word particles are arranged neatly and unevenly.
2. Check whether there is any tightening or falling off.
3. Check whether the ribbon is used repeatedly without ink.
4. Check whether the word grain and the color band are double shifted, and the top and bottom do not match, and the word grain is outside the color band.
5. Check whether the ribbon is rolled into a strip (remove all ink stuck on the circular shaft due to the ink falling off the ribbon.
6. No or insufficient air pressure, unable to reach the position.
7. The ribbon has been used up, and the machine automatically stops (look at the position of the stopper at the proximity switch).
8. Check the distance of each action of the ribbon. The distance is too close, the typing is not clear or there is no typing, and the ribbon is wasted if the distance is too far.
9. The unwinding tension adjusting nut is moderately tight, the color band cannot be pulled if it is too tight, and the alarm will often be sent if it is too loose, which will affect the speed.
10. The adjustment of the typing time (inside the packaging touch screen) is not clear and can be reduced.  
2、 When the sealing is not up to standard and not sealed
1. Check temperature
(1) It can be heated gradually when it is not sealed.
(2) Check whether the heating plate is intact.
(3) Check whether the front and rear cutterbed positions are appropriate.
(4) Check whether there are foreign matters in the front and rear cutterbed and clean them.
(5) Check whether the air pressure is normal.
(6) Check whether the packaging film is folded.
(7) Check whether the tool holder moves smoothly.
(8) Check whether the inner membrane of the packaging film is complete and excessively thick.
2. Seal deformation
(1) If the temperature is too high, the seal will not form or melt off.
(2) The packaging film is not aligned with the running edge.
3、 When the light spot is not made into a standard bag
1. Check whether the packaging film is normal.
2. Check whether there are foreign matters on the head of the optical fiber.
3. Check whether the optical amplifier reading is normal (normally 9 digits).
4. Check whether the optical fiber is scalded and whether the light source is normal.
5. Whether the bag length is normal and controlled by optical fiber.
6. Check whether the belt slips.
7. Check whether the belt slips.
8. Check whether the high-temperature tape is intact.
9. Check whether there is any foreign matter at the collar of the bag maker.
10. Check the distance and position between the optical fiber head and the packaging film.
11. Check whether the film release motor works normally.
12. Whether the rear facial mask is not tightened and falls off.
4、 Back seal moves back and forth, when not standard
1. Check whether the position of each block wheel is in line, and whether it is clamped or wrinkled.
2. Check the vertical seal position for deviation.
3. Check whether the synchronous belt is pulled or deviated.
4. Check whether the tensioning roller swings.
5. Check whether there is film sticking during film pulling.
6. Check whether the temperature of the middle seal is too high.
7. Check whether the packaging film pressing plate is intact and free of looseness.
8. Check whether there is knife sticking on the middle seal.
9. Check whether the support leg of the bag maker is stuck.
10. Check if there is any scraper in the bag making process.
5、 Air leakage of aluminum film
1. The inflation pressure is too high, and the seal is opened.
2. Check whether there are small materials.
3. Whether the temperature is appropriate.
4. Whether there is any problem with the material of the aluminum film itself and whether the inner membrane is intact.
5. Working pressure regulation.
6. Adjustment of sealing working time.
7. Check whether the heating plate is damaged.
8. Whether there is folding.
9. Whether there is film scraping during film pulling.
10. Whether there is leakage during blanking.
11. Whether the aluminum film has several layers of leakage on the surface during transportation and rolling.
6、 When the film cannot be pulled off
1. Check whether the synchronous belt has leakage.
2. Check the collar for foreign matters.
3. Check whether each guide film wheel is stuck.
4. Check whether the film release motor works.
5. Check whether the high-temperature tape is damaged.
