T-shirt bag making machine in the production process may encounter a variety of failures, these failures may affect the production efficiency and product quality. Here are some common faults and how to troubleshoot them
1. Mechanical failure
Film fracture
The cause of the failure: it may be that the extrusion temperature is too high leading to the film is too thin, or the screw speed is too fast, the material tension is too large.
Elimination method: Adjust the extrusion temperature and screw speed to ensure that the film thickness is moderate; Check material quality and tension Settings to avoid excessive tension resulting in film breakage.
Inaccurate cutting
Fault cause: cutting blade wear, cutting device position offset or improper adjustment.
Elimination method: check and replace the cutting blade regularly to ensure that the blade is sharp; Adjust the position and parameters of the cutting device to ensure cutting accuracy.
The feed film is not smooth
Failure cause: failure of film feeding mechanism, uneven tension of film material or damage of guide roller.
Elimination method: check the operation of the film feeding mechanism, repair or replace the damaged parts; Adjust the tension of the film material to ensure smooth film delivery; Check and replace worn roller guides.
2. Electrical failure
Motor fault
Cause of failure: motor overheating, overload or damage.
Elimination method: check the running state of the motor, clean up the dust and debris around the motor; Avoid overload operation of electrical length for a long time; If the motor is damaged, it should be replaced in time.
Control panel fault
Failure cause: control panel internal component damage, poor line contact or program error.
Elimination method: Check whether the display and indication of the control panel are normal; Check the internal components and line connections, if there is damage repair or replacement; If the program error, need to reset or programming.
3. Heat seal failure
Poor heat seal
Failure cause: insufficient heat sealing temperature, insufficient heat sealing time or uneven heat sealing pressure.
Elimination method: Adjust the heat sealing temperature and time to ensure the best heat sealing effect; Check the contact between the heat seal pressure and the hot surface to ensure that the pressure is even.
The heat seal is damaged
Fault cause: The heat seal is worn or aged after prolonged use.
Elimination method: Check and replace the heat seal regularly to ensure the quality of the heat seal.
4. Other faults
Excessive noise
Cause of failure: loose mechanical parts, insufficient lubrication or bearing damage.
Elimination method: Check the tightness of the mechanical parts to ensure that there is no loosening; Strengthen lubrication maintenance of equipment; If the bearing is damaged, it should be replaced in time.
Temperature control is unstable
Fault cause: Temperature sensor failure, temperature controller damage or aging heating element.
Elimination method: check the accuracy and stability of the temperature sensor; If the temperature controller is damaged, replace it with a new one. Inspect and replace aging heating elements.
General steps for troubleshooting
Stop inspection: After the fault is found, the first thing should be stopped immediately for inspection to avoid the expansion of the fault or cause greater losses.
Fault analysis: According to the fault phenomenon and the working principle of the machine, analyze the cause and possible impact of the fault.
Troubleshooting: According to the cause of the fault, take corresponding troubleshooting measures to repair or replace the damaged parts.
Test machine verification: After troubleshooting, test machine verification is carried out to ensure that the machine returns to normal working state and meets the production requirements.
