Solution to the failure of mask ear strap welding machine (2)

Mask ear strap welding machine is a machine that welds ear straps on both sides of the mask; it is divided into automatic mask ear strap welding machine and semi-automatic mask ear strap welding machine; among them, the automatic ear strap welding machine is mainly used for the production of flat masks.

 

In the production process, if the earband welding machine fails, it needs to be repaired by professionals. Strong H Machinery Technology Co., Ltd. provides you with the following solutions for the earband welding machine failure:

1. The current is too large and overloaded during welding

 

Reasons: 1. The air pressure is too high; 2. The welding head is too large and the impulse current is large; 3. The trigger pressure is high and the delay time is long; 4. The secondary rod ratio is too high

 

Solution: 1. Lower the air pressure; 2. Use a higher-power model; 3. Lower the trigger pressure to reduce the delay time; 4. Use a low-multiplier two-stage rod.

2. The trigger switch welding head does not fall

 

Reasons: 1. The emergency stop switch is not reset; 2. The trigger switches cannot be triggered at the same time or one of them is in poor contact; 3. There is a problem with the program control board

 

Solution: 1. Reset the emergency stop switch; 2. Test so that the two trigger switches can be triggered at the same time; 3. Test the program board to eliminate the fault, generally an IC problem.

3. After the switch is triggered, the ultrasonic time is very long or the pressure holding time is very long. Sometimes the no-load test is abnormal, which can eliminate the environment that cannot get rid of the abnormal situation. The original welding sound energy may change, resulting in unsatisfactory sound energy transmission.

 

Reason: the welding time or holding pressure time band switch is open.

 

Solution: Adjust the contact of the band switch to make good contact.

4. After the switch is triggered, the ultrasonic cannot be triggered

 

Reasons: 1. The pressure trigger switch is damaged; 2. There is a problem with the program board.

 

Solution: 1. Replace the pressure trigger switch or small spring; 2. Check the program board to eliminate the fault, usually an IC problem.
