Film pasting mechanism on film pasting machine for soft packing lithium battery

The utility model discloses a film pasting mechanism on a film pasting machine for a soft packing lithium battery. The film pasting mechanism comprises a rack, wherein a drive rubber shaft and a driven rubber shaft in parallel are arranged on the rack; a clearance with a freely adjustable size is arranged between the drive rubber shaft and the driven rubber shaft; driven suckers are respectively arranged on two sides of the drive rubber shaft and the driven rubber shaft; two auxiliary anti-winding rollers corresponding to the driven suckers are parallelly arranged above the drive rubber shaft and the driven rubber shaft; a double-shaft air cylinder is arranged on one side of the drive rubber shaft; a tension strip is fixedly arranged on the double-shaft air cylinder; sliding shafts capable of controlling pressure between the drive rubber shaft and the driven rubber shaft are fixedly connected to two ends of the tension strip; a gear reduction motor matched with the drive rubber shaft and synchronous with the drive rubber shaft is fixedly arranged on the rack; and in addition, a proximity switch capable of sensing a workpiece insertion status and controlling the pressure of the double-shaft air cylinder and the rotation speed of the gear reduction motor according to the workpiece insertaion status is arranged. Due to the utilization of the film pasting mechanism, no bubbles are generated during film pasting, a film can be pasted tightly, the speed is quick, and the efficiency is high.
