[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The plastic self-sealing bag processing flat-mouth machine involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] This utility model provides a flat-mouth machine for processing plastic self-sealing bags, including a support plate 1. Support legs 2 are fixedly connected to the four corners of the bottom surface of the support plate 1. Side plates 3 are fixedly connected to the top surface of the support plate 1 near both sides. Two rotating rollers 5 are rotatably connected to the upper part of each of the two side plates 3. Driven wheels 4 are fixedly connected to one end of each of the two rotating rollers 5. Transmission belts 6 are movably sleeved on the outer walls of each of the two driven wheels 4. Transmission wheels are fixedly connected to one end of each of the other two rotating rollers 5. One side of the inner wall of each of the two transmission belts 6 is movably sleeved on the outer wall of each of the two transmission wheels. A drive motor 7 is fixedly connected to one side of each of the two transmission wheels. Two conveyor belts 8 are movably sleeved on the outer walls of the four rotating rollers 5.

[0023] By setting up pressure plates 17, during operation, plastic bags are placed on two conveyor belts 8, which transport the plastic bags to the bottom of the two pressure plates 17. Then, the cylinder 10 drives the hydraulic rod 11 to extend and retract, pushing the connecting plate 12. The connecting plate 12 drives the cutter 18 and the two pressure plates 17 to move downward, so that the bottom surface of the two pressure plates 17 presses down on the plastic bags. The cutter 18 cuts the plastic bags, and after cutting, they are transported to the collection box 19 by the two conveyor belts 8, thereby improving work efficiency.

[0024] Furthermore, support frames 9 are fixedly connected to both sides of the two side plates 3. A cylinder 10 is fixedly connected to the middle of the top surface of the support frame 9. A hydraulic rod 11 is fixedly connected to the bottom end of the cylinder 10. The outer wall of the hydraulic rod 11 penetrates the middle of the bottom surface of the support frame 9. A connecting plate 12 is fixedly connected to the bottom end of the hydraulic rod 11.

[0025] By setting up conveyor belts 8, when the two pressure plates 17 move down to press down on the plastic bag, the two conveyor belts 8 stop. There is a gap between the two conveyor belts 8, and the cutter 18 moves down through the gap to cut the plastic bag, thereby improving the efficiency of cutting plastic bags.

[0026] Furthermore, positioning rods 13 are fixedly connected to the top surface of the connecting plate 12 near both sides. The outer walls of the two positioning rods 13 penetrate the top surface of the support frame 9 near both sides. Limiting blocks 14 are fixedly connected to the top of the two positioning rods 13. Four telescopic rods 15 are fixedly connected to the bottom surface of the connecting plate 12.

[0027] By setting a return spring 16, the two pressure plates 17 are flush with the bottom of the cutter 18. When the two pressure plates 17 press down on the plastic bags on the two conveyor belts 8, the elasticity of the four telescopic rods 15 drives the two pressure plates 17 to retract. At this time, the cutter 18 still moves downwards towards the gap between the two conveyor belts 8 and cuts the plastic bags. After cutting, the hydraulic rod 11 drives the connecting plate 12 to move upwards, thereby driving the cutter 18 to move upwards. The outer wall of the four telescopic rods 15 is provided with a return spring 16. The elasticity of the four return springs 16 slowly resets the four telescopic rods 15 and resets the two pressure plates 17. Then the two conveyor belts 8 transport the cut plastic bags to the collection frame 19.

[0028] Furthermore, a return spring 16 is movably sleeved on the outer wall of each of the four telescopic rods 15 near the bottom. Two pressure plates 17 are fixedly connected to the bottom of the four telescopic rods 15. A cutter 18 is fixedly connected to the middle of the bottom surface of the connecting plate 12. A collection frame 19 is fixedly connected to one side of the support plate 1. A baffle 20 is fixedly connected inside the collection frame 19. Two collection slots 21 are opened inside the collection frame 19.

[0029] By setting up a collection frame 19, with a baffle 20 in the middle of the collection frame 19, the width of the baffle 20 is consistent with the distance between the two conveyor belts 8. The cut plastic bags are dispersed into the two collection troughs 21 by the baffle 20, thus demonstrating the convenience and practicality of the equipment.

[0030] The working principle of this utility model is as follows: During operation, a plastic bag is placed on two conveyor belts 8. The conveyor belts 8 transport the plastic bag to below two pressure plates 17. Then, a cylinder 10 drives a hydraulic rod 11 to extend and retract, pushing a connecting plate 12. The connecting plate 12 causes the cutter 18 and the two pressure plates 17 to move downwards, pressing the bottom surfaces of the two pressure plates 17 onto the plastic bag. The cutter 18 cuts the plastic bag, and the cut bag is then transported to a collection frame 19 via the two conveyor belts 8. When the two pressure plates 17 move downwards and press down on the plastic bag, the two conveyor belts 8 stop. There is a gap between the two conveyor belts 8, and the cutter 18 moves downwards through this gap to cut the plastic bag. The bottom ends of the two pressure plates 17 are flush with the cutter 18. After the two pressure plates 17 press down on the plastic bag on the two conveyor belts 8, the plastic bag is transported to a collection frame 19. The elasticity of the four telescopic rods 15 causes the two pressure plates 17 to retract. At this time, the cutter 18 continues to move downwards towards the gap between the two conveyor belts 8 and cuts the plastic bag. After cutting, the hydraulic rod 11 drives the connecting plate 12 to move upwards, thereby driving the cutter 18 to move upwards. The outer walls of the four telescopic rods 15 are provided with return springs 16. The elasticity of the four return springs 16 slowly resets the four telescopic rods 15 and the two pressure plates 17. Then, the two conveyor belts 8 transport the cut plastic bags to the collection frame 19. The middle of the collection frame 19 is provided with a baffle 20. The width of the baffle 20 is consistent with the gap between the two conveyor belts 8. The baffle 20 disperses the cut plastic bags into the two collection troughs 21, thus demonstrating the convenience and practicality of the equipment.
