A first U-shaped plate 16 is fixedly connected to the top of the support plate 1 near one end. A lifting plate 17 is provided inside the first U-shaped plate 16. A cutting blade 19 and a heat sealing head 20 are installed at the bottom of the lifting plate 17. A second U-shaped plate 21 is fixedly connected to one side of the lifting plate 17. A sliding rod 22 is symmetrically connected to the bottom of plate 21 and slides through it. A disc 24 is fixedly connected to the top of the sliding rod 22, and a spring 25 is fixedly connected to the top of the disc 24. The top of the spring 25 is fixedly connected to the inner top wall of the second U-shaped plate 21. A pressing plate 23 is fixedly connected to the bottom of the sliding rod 22. With the above arrangement, the first motor 9 can drive the rotating rod 5 to rotate. The rotation of the rotating rod 5 can drive the rotating gear 8 to rotate. The rotation of the rotating gear 8 can drive another rotating gear 8 to rotate. The rotation of the rotating gear 8 can drive the rotating rod 5 to rotate. The rotation of the rotating rod 5 can drive the plastic bag to be conveyed. At the same time, the rotation of the bidirectional screw 14 can drive the fixed block. The movement of the fixed block 13 can drive the connecting plate 11 to move, which can adjust the distance between the limiting plates 12, thereby achieving the effect of positioning the edge of the plastic bag during the conveying process. When the plastic belt moves to below the first U-shaped plate 16, the lifting plate 17 can be pushed down by the hydraulic cylinder 18. The lowering of the lifting plate 17 can drive the second U-shaped plate 21 to lower. The second U-shaped plate 21 can push the spring 25 to squeeze the disc 24. At this time, the disc 24 pushes the sliding rod 22 to drive the squeezing plate 23 to clamp the plastic belt. This allows the cutting blade 19 and the sealing head 20 to cut and seal the plastic bag.

[0022] like Figure 1 As shown, support legs 2 are fixedly connected to the bottom of the support plate 1 and near the four corners. The support legs 2 are trapezoidal in shape.

[0023] like Figure 4As shown, the surfaces of the two fixed plates 4 are fixedly connected to the first motor 9, the output end of the first motor 9 is fixedly connected to one end of the rotating rod 5, both ends of the bidirectional screw 14 penetrate the inner wall of the groove 3 and are rotatably connected to its bearing, and a second motor 15 is fixedly connected to one side wall of the support plate 1, the output end of the second motor 15 is fixedly connected to one end of the bidirectional screw 14.

[0024] like Figure 3 As shown, the surface, top and bottom of the movable sleeve 10 are slidably connected to a limiting rod 7, and the two ends of the limiting rod 7 are fixedly connected to the fixing plate 4 and the inner wall of the groove 3.

[0025] like Figure 2 As shown, a hydraulic cylinder 18 is fixedly connected to the top of the first U-shaped plate 16 and near the center. The output end of the hydraulic cylinder 18 passes through the first U-shaped plate 16 and is fixedly connected to the lifting plate 17.

[0026] like Figure 2 and Figure 4 As shown, a gear cover 26 is fixedly connected to one side of the support plate 1 and at the location of the rotating gear 8. The rotating gear 8 is located inside the gear cover 26 and is adapted to it.

[0027] The device's operation and working principle are as follows: The first motor 9 drives the rotating rod 5 to rotate, which in turn drives the rotating gear 8 to rotate. The rotating gear 8 in turn drives another rotating gear 8 to rotate, which in turn drives the rotating rod 5 to rotate, thus conveying the plastic bag. Simultaneously, the second motor 15 drives the bidirectional screw 14 to rotate, which in turn moves the fixed block 13. The movement of the fixed block 13 moves the connecting plate 11, adjusting the distance between the limiting plates 12. This allows for positioning of the plastic bag's edge during conveying. When the plastic bag moves below the first U-shaped plate 16, the hydraulic cylinder 18 pushes the lifting plate 17 to descend. The descent of the lifting plate 17 causes the second U-shaped plate 21 to descend, which in turn pushes the spring 25 to squeeze the disc 24. The disc 24 then pushes the sliding rod 22, which in turn drives the squeezing plate 23 to clamp the plastic bag. This allows the cutting blade 19 and the sealing head 20 to cut and seal the plastic bag.
