The first pulley 711 and the second pulley 712 are connected by a belt drive.

[0024] In the above technical solution, considering the use of a cam to squeeze the hot pressing plate so that the two hot pressing plates are close to each other for heat sealing, the cam will be seriously worn out after long-term use. In order to solve this problem, the specific operations are as follows:

[0025] Reference Figure 1 and Figure 4 In a preferred embodiment, the output end of the motor 2 drives the second pulley 712 to rotate, so that the first pulley 711 drives the two gears 710 to rotate towards each other, and then the two rollers 707 drive the two rotating blocks 708 to rotate towards each other, so that the two rollers 709 squeeze the two lifting plates 703 in the direction of approaching each other, and the two heat sealing strips 706 begin to seal the bag. As the sealing is completed, the rollers 709 gradually disengage from squeezing the lifting plates 703. Under the tension of the spring 704, the lifting plates 703 begin to reset. The heat sealing mechanism provided can achieve rapid heat sealing of the bag. The pressing method of the roller 709 will not cause wear of the lifting plates 703, making the heat sealing more stable, extending the service life of the equipment, and having a simple structure and strong practicality.

Through the controller 11, it is convenient for the staff to control the opening and closing of the motor 2, the conveying roller 5 and the heat sealing strip 706, and the operation is more convenient.

[0028] Working principle: In actual use, the staff first transports the raw materials into the interior of the production box 1 through the feed port 3, and then transports them through the rotating rod 4 and the conveying roller 5 to enter between the two pressing plates 705. Then the staff turns on the motor 2, and the output end of the motor 2 drives the No. 2 pulley 712 to rotate, so that the No. 1 pulley 711 drives the two gears 710 to rotate towards each other, and then the two rollers 707 drive the two rotating blocks 708 to rotate towards each other, so that the two rollers 709 squeeze the two lifting plates 703 towards each other, and the two heat sealing strips 706 begin to seal the bag. As the sealing is completed, the roller 709 gradually disengages from the squeezing of the lifting plate 703. Under the tension of the spring 704, the lifting plate 703 begins to reset, and the sealed bag is produced from the discharge port 6. At this point, the staff has completed the eight-side sealing of the bag.
