Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0023] As shown in the figure, a vest bag making and punching machine includes a frame 1, on which a traction mechanism 2 and a cutting mechanism 3 are provided. The traction mechanism 2 includes a material placement plate 21, a sliding plate 22 and a material clamping claw 23. The cutting mechanism 3 includes a bag receiving seat 31, a knife seat 32 and a cutter. The material placement plate 21 is fixedly arranged at the front end of the frame 1, and the sliding plate 22 can be horizontally slidably arranged on the frame 1 and is connected to the drive structure. A plurality of the material clamping claws 23 are arranged on the sliding plate 22. The bag receiving seat 31 is fixedly provided on the frame 1 on one side of the material placing plate 21, so that a blanking gap is formed between the bag receiving seat 31 and the material placing plate 21, and the knife seat 32 can be longitudinally slidably provided on the frame 1 above the bag receiving seat 31 and is transmission connected to the booster cylinder 33 provided on the frame 1, and the cutter is provided on the knife seat 32 and opposite to the bag receiving seat 31, and the sliding plate 22 is fixedly connected to a material stripping plate 24 whose lower end is flush with the end face of the bag receiving seat 31.

[0024] Specifically: the driving structure includes a synchronous belt 25, a guide wheel 26 and a track 27. The two tracks 27 are fixedly arranged on the frame 1 and are respectively located on both sides of the sliding plate 22. Several guide wheels 26 are rotatably arranged on the sliding plate 22 and the guide wheels 26 abut against the track 27. The two synchronous belts 25 are arranged on the frame 1 and are respectively located on both sides of the sliding plate 22. The two ends of the sliding plate 22 are respectively fixedly connected to the two synchronous belts 25.

[0025] Specifically: the clamping jaw 23 includes a fixed clamping jaw 231, a movable clamping jaw 232 and a clamping jaw cylinder 233, the fixed clamping jaw 231 is fixedly set on the sliding plate 22, the movable clamping jaw 232 is hinged to the fixed clamping jaw 231, the clamping jaw cylinder 233 is hinged to the fixed clamping jaw 231 and the output shaft of the clamping jaw cylinder 233 is hinged to the movable clamping jaw 232.

[0026] Specifically, the cutting mechanism 3 further includes a pressing rod 34 , which is longitudinally slidably arranged on the frame 1 above the bag receiving seat 31 and is transmission-connected to a pressing cylinder 35 arranged on the frame 1 .

[0027] In the above structure, the bags that have been heat-sealed and heat-cut are stacked on the loading plate 21. When the bags are stacked to a certain height, the synchronous belt 25 drives the sliding plate 22 and drives the guide wheel 26 to roll on the track 27. The sliding plate 22 slides along the track 27 toward the loading plate 21, and drives the clamping claw 23 to move toward the loading plate 21. The cooperation between the guide wheel 26 and the track 27 ensures the stability and smoothness of the sliding plate 22 and the clamping claw 23 during the sliding process. When the clamping claw 23 slides to the side of the bag placed on the loading plate 21, the clamping air is The cylinder drives the movable clamping jaw 232 to swing in the direction away from the fixed clamping jaw 231, so that the fixed clamping jaw 231 and the movable clamping jaw 232 slide to the lower end and the upper end of the bag respectively. After the clamping cylinder drives the movable clamping jaw 232 to swing toward the fixed clamping jaw 231, the fixed clamping jaw 231 clamps the bag. Then the sliding plate 22 drives the clamping jaw 23 and the bag to slide in the direction away from the material loading plate 21, driving the bag to leave the material loading plate 21 and move to the bag receiving seat 31. The pressing cylinder 35 drives the pressing rod 34 to move downward to press the bag on the bag receiving seat 31, and then the bag is pressed. The pressure cylinder 33 drives the knife seat 32 and drives the cutter to move toward the bag placed on the bag receiving seat 31 to punch and cut the bag. During the punching and cutting process, the bag is pressed by the pressing rod 34 and remains stable, ensuring the accuracy of the punching and cutting. After the punching and cutting is completed, the cut waste is pressed by the pressing rod 34 and retained on the bag receiving seat 31, and the bag continues to move away from the material plate 21 with the clamping claw 23 to realize the unloading, completing a single punching and cutting operation. When the sliding plate 22 drives the clamping claw 23 to move toward the material plate 21 for unloading The scrap material on the bag receiving seat 31 is moved to the material receiving plate 21 by the sliding plate 22, and then falls through the gap between the bag receiving seat 31 and the material receiving plate 21 after leaving the bag receiving seat 31, which is convenient for collecting the scrap material and ensures that no scrap material remains on the bag receiving seat 31 before the next punching and cutting operation is carried out, thereby avoiding affecting the next punching and cutting operation, thereby ensuring the continuous punching and cutting operation and ensuring production efficiency.

[0028] In addition, a rubber scraper 241 is provided at the lower end of the material stripping plate 24. The rubber scraper 241 scrapes across the end surface of the bag receiving seat 31 as the material stripping plate 24 moves, thereby ensuring that the material stripping plate 24 can move the waste material retained on the end surface of the bag receiving seat 31 to the blanking gap and drop it.

[0029] In addition, the height of the material placing plate 21 is higher than the end face of the bag receiving seat 31, and the end of the material placing plate 21 is formed with a guide plate 211 that is tilted downward and extends into the blanking gap. The guide plate 211 is provided with a blanking port 212, and the material placing plate 21 is provided with a plurality of clamping grooves 213 that are aligned one by one with a plurality of clamping claws 23. The height of the material placing plate 21 is set higher than the end face of the bag receiving seat 31 to ensure that the material shifting plate 24 moves the waste material retained on the bag receiving seat 31 to the blanking gap when shifting. The bag will not move excessively onto the material placement plate 21 when there is a gap, ensuring that the waste can fall through the drop opening 212, and the guide plate 211 plays a receiving role between the material placement plate 21 and the bag receiving seat 31 when the clamping claws 23 clamp the bag and transfer it from the material placement plate 21 to the bag receiving seat 31, ensuring that the bag can be stably transferred to the bag receiving seat 31, and the clamping groove 213 allows the fixed clamping claws 231 to extend into it when the clamping claws 23 clamp the bag to cooperate with the movable clamping claws 232 to achieve bag clamping.

[0030] In addition, the cutting mechanism 3 also includes a leveling brush 36, which can be longitudinally slidably arranged on the frame 1 between the material placement plate 21 and the bag receiving seat 31, and the leveling brush 36 is transmission-connected to a leveling cylinder 37 arranged on the frame 1. In the process of the clamping claw 23 clamping the bag and transferring it from the material placement plate 21 to the bag receiving seat 31, the leveling cylinder 37 drives the leveling brush 36 to press against the bag being transferred, and the bag is smoothed by scraping the leveling brush 36 on the bag, so that the bag transferred to the bag receiving seat 31 is guaranteed to be flat, thereby ensuring the quality of punching and cutting.

[0031] In addition, the frame 1 is further provided with a folding mechanism 4 located on one side of the cutting mechanism 3, and the folding mechanism 4 includes a folding pressure plate 41 and a folding support plate 42 which are longitudinally slidably arranged on the frame 1 and are opposite to each other up and down. The folding pressure plate 41 and the folding support plate 42 are respectively connected to the first folding cylinder 43 and the second folding cylinder 44 provided on the frame 1 for transmission. The side end of the folding support plate 42 away from the cutting seat is provided with a plurality of folding clamping grooves 421 which are aligned one by one with the plurality of clamping claws 23. After the cutting mechanism 3 completes the punching and cutting of the bag, the clamping claws 23 drive the bag to leave the bag receiving seat 31, and the second folding cylinder 44 drives the folding support plate 42 to move the bag away from the bag receiving seat 31. The plate 42 moves upward to support the bag, and at the same time, the first folding cylinder 43 drives the folding pressure plate 41 to move downward to cooperate with the folding support plate 42 to clamp the bag. Then the clamping claw 23 releases the clamping of the bag and moves backward for a distance, so that the rear end of the bag hangs down and folds along the side end of the folding support plate 42 where the folding clamping groove 421 is provided. Then the clamping claw 23 moves toward the bag and folds the hanging part of the bag, and clamps the bag through the folding clamping groove 421 to realize the folding of the bag. After the folding support plate 42 and the folding pressure plate 41 are reset, the folded bag is driven to be unloaded in a folded state, which is convenient for subsequent packaging and bundling of the bag, thereby improving production efficiency.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
