1. Partial failure of the film guide groove: The film cannot bite into the upper pillow packer heat roll, or come off the heat roll, or be misaligned.
Reason 1: The center of film, guide groove, longitudinal sealing roller and horizontal sealing roller are not in a straight line. Reason
2: The film guide groove is too inclined. Reason
3: The speed of the eccentric sprocket of the horizontal sealing heat roller is abnormal.
Adjustment method 1: Roll up the vertical sealing pillow packaging machine and turn the adjusting knob to the right to increase the pressure, and the thickness of the film will be stretched. It should be noted that the seal cannot be sealed if it is stretched too much.
Adjustment method 2: reduce the pressure of the longitudinal heat sealing roller, the film cannot be clamped in if the pressure is too large, and it may be extruded. Adjustment method 3: The clamping amount of the longitudinal sealing roller is more than usual, generally 10MM should be clamped in 7MM. Adjustment method
4: If the two ends are still uneven through the above adjustment of the pillow packaging machine, bend the film beyond the guide groove on the side to bend it inward. Adjustment method
5: There is an error in the center line of the film guide groove, and the manufacturing defect should be replaced.
