Common faults and treatment methods of packaging machines

A. Unclear dating, no dating:

    1. Check whether the characters are arranged neatly and unevenly.

    2. Check whether there is any tightening or falling off of individual characters.

    3. Check whether the ribbon is used repeatedly without ink.

    4. Check that the characters and the ribbon are multiple shifted, do not match up and down, and the character is on the outside of the ribbon.

    5. Check whether the ribbon is rolled into a strip (remove all the ink sticking to the round shaft due to the ink falling off the ribbon.)

    6. There is no or insufficient air pressure, and it cannot reach the position.

    7. When the ribbon is used up, the machine automatically function will stop (see the position of the stopper at the proximity switch).

    8. Check the distance of each movement of the ribbon. The distance is too close, the printing is not clear or there is no printing, and the distance is too far to waste the ribbon.

    9. The tension of the unwinding tension adjustment nut is moderate, and the ribbon cannot be pulled if it is too tight, and the alarm is often alarmed when it is too loose, which affects the speed.

  10. The adjustment of printing time (in the packaging touch screen) is not clear, so it can be added less.

B. When the sealing is not up to standard or not sealing:

    1. Check the temperature

(1) It can gradually increase the temperature when it is not sealed.

(2) Check whether the heating plate is in good condition.

(3) Check whether the position of the front and rear tool holders is moderate.

(4) Check whether there is any foreign matter in the front and rear tool holders, and clean them up.

(5) Check whether the air pressure is normal.

(6) Check whether the packaging film is folded.

(7) Check whether the movement of the knife rest is smooth.

(8) Check whether the inner film of the packaging film is intact and whether it is too thick.

    2. Sealing deformation

(1) If the temperature is too high, the seal will not form or melt.

(2) The packaging film is not aligned with the running edge.

C. The light spot is running out when it is not made into a standard bag

    1. Check whether the packaging film is normal.

    2. Check whether there is any foreign matter on the optical fiber.

    3. Check whether the reading of the optical amplifier is normal.

    4. Check whether the optical fiber is scalded and whether the light source is normal.

    5. Whether the bag length is normal and whether it is controlled by optical fiber.

    6. Check whether the belt is slipping.

    7. Check whether there is any foreign matter at the collar of the bag maker.

    8. Check the distance and position between the optical fiber head and the packaging film.

    9. Check if the film motor is working properly.

   10. Whether the back film is not tightened or falls off.

D. The back seal moves back and forth when it is not standard:

    1. Check whether the position of each retaining wheel is in a line before and after, whether it is clamped or wrinkled.

    2. Check if there is any deviation in the vertical seal position.

    3. Check the phenomenon of non-pull film in the synchronous belt.

    4. Check if the tension roller is swinging.

    5. Check whether there is a film jam during the film pulling process.

    6. Check whether the middle sealing temperature is too high.

    7. Check whether the packaging film pressure plate is intact and not loose.

    8. Fancy whether the horizontal seal is sticky or not.

    9. Check if there is any jam in the supporting feet of the bag maker.

    10. Check whether there is a scraper in the bag-making process.

E. Aluminum/plastic film leakage

    1. The inflation pressure is too high, and the seal is opened.

    2. Whether there is any small material clamping.

    3. Whether the temperature is appropriate.

    4. Whether there is any problem with the material of the aluminum film itself, and the inner film is in good condition.

    5. Working pressure adjustment.

    6. Adjust the sealing working time.

    7. Whether the heating film is damaged.

    8. Whether it is folded or not.

    9. Whether the film is scraped during the film pulling process.

    10. Whether there is any leakage during the blanking process.

   11. During the transportation and rolling of the aluminum film, whether the film has several layers of punctures on the surface.

F. When the film cannot be pulled off:

    1. Check whether the timing belt is missing.

    2. Check if there is any foreign matter at the collar.

    3. Check whether the film guide wheels are stuck or not.

    4. Check whether the film motor is working.
