Every production process from material feeding to finished product discharge is controlled by PLC. Therefore, if any problem occurs or material runs out, the machine will automatically stop, alert and the display screen will display the potential failure reason, greatly reducing machine downtime and improving production efficiency. Strong turbofan cooling system ensures the stability of ultrasonic welding. Reasonable and organized electric circuit and air pipe arrangement—two colors of airpipe differentiate the inlet and outlet air pipe to reduce the operation errors. Fully automatic production process is enabled from fabric feeding, pleating, ultrasonic welding, cutting to finished product discharge.
