Common reasons for paper jams, irregular packaging, and other faults during the operation of paper cup and paper bowl packaging machines may include the following:
Common causes of paper jams:
Paper supply control lever problem: The paper supply control lever may be stuck, causing the paper to be unable to be transported normally, resulting in paper jams. At this time, you need to check and solve the cause of the jam.
Paper supply proximity switch failure: The paper supply proximity switch may be damaged or malfunction, causing the packaging machine to be unable to accurately detect the paper position, causing paper jams. At this time, you need to replace the damaged paper supply proximity switch.
Start capacitor failure: A failure in the starting capacitor may cause the paper supply motor to fail to operate normally, thereby affecting the transportation of paper. At this time, you need to replace the starting capacitor in time.
Paper quality problems: The paper itself may have irregularities, rough edges, and other problems, which may cause the paper to get stuck during transportation. At this time, you need to trim off the unqualified packaging materials.
Common causes of abnormal packaging failure:
Heat sealer body temperature problem:
No heating: It may be caused by packaging machine circuit failure, heating tube failure or fuse damage. At this time, you need to check the circuit and replace the heating tube or fuse.
Temperature cannot be controlled: It may be caused by temperature regulator failure or thermocouple circuit short circuit. At this time, you need to replace the temperature regulator or thermocouple.
Sealing problem:
The sealing is not tight: It may be caused by low sealing temperature, uneven material distribution or uneven pressure at the sealing point. At this time, you need to increase the sealing temperature, trim irregular materials or adjust the sealing pressure value.
Improper sealing: It may be caused by incorrect heat sealer body position setting. At this time, you need to adjust the position of the heat sealer body.
Bag pulling motor failure: The bag pulling motor may fail, resulting in failure to operate normally or inaccurate bag pulling. At this time, you need to check the circuit, replace the bag pulling proximity switch, controller or stepper motor driver.
Color mark positioning problem: It may be caused by frequent use of the roller being worn flat or the bag length setting value being inaccurate. At this time, you need to replace the roller or set the accurate bag length setting value.
