The paper bag machine equipment has been used for a long time, and there will be some small problems. When these small problems are encountered, the correct method should be used to deal with them in a timely manner, and the paper bag machine equipment needs to be maintained in daily life. Now what Xiaobian wants to introduce to you is the common faults and solutions of paper bag machine equipment.
The computer controller of the paper bag machine often has some failures. In order to solve these failures, we need to know the type of the failure and the solution. If it cannot be started by pressing the start button, then you need to turn off the power and restart, then check whether the inverter alarms. It is also necessary to check whether the intermediate relay is working normally and replace it if not.
1. Check whether the U, V, W, and 380V voltages are normal. If all are normal, you need to replace the motor.
2. The computer display does not display or the keys do not work:
① First check whether the switching power supply has DV 24V voltage output. Or the proximity switch is damaged and disconnected, causing the power indicator to be off, and there is no 24V output. ② Replace the proximity switch or switching power supply. ③ Replace the computer.
3. The machine can start, but the feeding rubber roller does not turn and does not feed:
① Check if the servo driver has an alarm. If there is no alarm, replace the servo driver. ② Check whether the proximity switch is burnt out. If it is burnt out, replace the proximity switch. ③ Replace the servo motor.
4. The machine starts working, but the feeding rubber roller feeds slowly or feeds for a long time:
① Mainly check whether the current value of the "pulse equivalent" parameter in the "modification" of the computer is "0.107".
5. The rear unloading DC motor or conveyor motor does not rotate and does not work:
① Check if the overcurrent indicator in the upper left corner of the DC motor speed control board is on. If the overcurrent indicator is on, turn off the main power for 5 seconds before turning on the power. If the overcurrent indicator is still on, replace the DC motor speed control board. ② Check if the speed control potentiometer fails, if it fails, replace the potentiometer. ③ Check if the carbon brush of the DC motor is excessively worn, if it is worn out, replace the carbon brush.
6. The punching machine does not punch or punch through:
① First check the parameter settings in the computer: Is the current value of "Punch Delay" 50 to 80 milliseconds, the current value of "Punch Delay" 30 milliseconds, and the current value of "Function 17" is 1 punch ". ② Check whether the punch is worn. ③ Check if the air pressure is above 0.6MPA. ④ Check whether the punched intermediate relay is working normally (replace). ⑤ Check whether the solenoid valve is damaged (replace).
