[0002] Woven bags, also known as snakeskin bags, are a type of plastic bag used for packaging. They are typically made from various chemical plastics such as polyethylene and polypropylene. Cutting and sewing are crucial steps in the production of woven bags. In traditional production methods, it was difficult to ensure precise and uniform dimensions when cutting woven bags, hence the invention of specialized cutting and sewing devices.
[0003] In existing technologies, to ensure neat edges and strong stitching of woven bags, cutting and sewing devices are typically equipped with folding plates and guide plates. These components play a crucial role in the forming process of woven bags, helping the material to be processed according to a preset shape and size through precise guiding and folding actions. However, the problem is that the openings and positions of the folding plates and guide plates in existing woven bag cutting and sewing devices are often fixed. This means that when production needs change from one thickness of woven bag to another, the original folding plates and guide plates may no longer meet the new production requirements. At this time, operators have to perform tedious disassembly and replacement work to adjust the device to adapt to the new production specifications. This process not only consumes a lot of time and manpower, but may also lead to a decrease in equipment accuracy due to errors in the disassembly and installation process, thus affecting product quality. Therefore, it is necessary to improve the woven bag cutting and sewing device to solve the above problems. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0022] Please see Figure 1 - Figure 5This utility model provides an embodiment of an adjustable snakeskin bag cutting and sewing device, including a device body 1 and a conveying mechanism. The device body 1 has a conveying mechanism for transporting snakeskin bags inside. A first threaded rod 21 is rotatably connected inside the device body 1. A first knob 22 is fixedly connected to the outside of the first threaded rod 21. A sliding seat 23 is threadedly connected to the outside of the first threaded rod 21 and slidably connected inside the device body 1. A sewing device body 24 for sewing is provided on the top of the sliding seat 23. A first fixed shell 224 is fixedly connected to the top of the sliding seat 23. A second threaded rod 25 is rotatably connected inside the first fixed shell 224. A second knob 26 is fixedly connected to the top of the second threaded rod 25. The device has an external threaded connection to a first connecting bracket 27, which is slidably connected inside the first fixed housing 224. A lower guide plate 29 is fixedly connected to the outside of the first connecting bracket 27, and an upper guide plate 28 is fixedly connected to the top of the sliding seat 23. A guide wheel assembly body 210 is provided on the outside of the first connecting bracket 27. During use, the first knob 22 is rotated according to actual needs, driving the first threaded rod 21 to rotate. When the first threaded rod 21 rotates, it drives the sliding seat 23 to slide inside the device body 1, thereby adjusting the position of the sliding seat 23. Then, according to the required thickness of the burlap sack, the second knob 26 is rotated. When the second knob 26 rotates, it drives the second threaded rod 25 to rotate, which in turn drives the first connecting bracket... The frame 27 slides inside the first fixed shell 224 to adjust the position of the upper guide plate 28 and the guide wheel assembly body 210. During subsequent operation, the burlap sack is conveyed via a conveying mechanism. When the burlap sack reaches the sliding seat 23, the guide wheel assembly body 210 initially folds the edge of the burlap sack to be sewn. Then, the upper guide plate 28 and lower guide plate 29 cooperate to further fold it. At this point, the burlap sack continues to move, and the sewing device body 24 sews it. The device body 1 has a groove at a relative position to the sliding seat 23. The sliding seat 23 is slidably connected inside the groove. The groove restricts the sliding of the sliding seat 23, allowing it to slide linearly inside the device body 1 and preventing it from detaching from the device body 1. The tilting affects the position of the sewing device body 24 and the guide wheel assembly body 210. The first fixed shell 224 has a rotating groove at the relative position of the second threaded rod 25. The first fixed shell 224 is rotatably connected inside the rotating groove. The rotating groove restricts the rotation of the second threaded rod 25, preventing the second threaded rod 25 from moving with the sliding seat 23 and causing it to detach from the device body 1. The top of the device body 1 is fixedly connected to the first fixed bracket 211. The inside of the first fixed bracket 211 is fixedly connected to the first telescopic rod 212. The bottom of the first telescopic rod 212 is fixedly connected to the second connecting bracket 213. The outside of the second connecting bracket 213 is slidably connected to the pressure plate 214. The pressure plate 214 and the second connecting bracket 213 are fixedly connected to the first spring 215.The bottom of the second connecting bracket 213 is fixedly connected to the cutter body 216. A rotating bracket 217 is rotatably connected to the outside of the second connecting bracket 213. The inside of the rotating bracket 217 is a first conveying roller body 218. The top of the device body 1 is fixedly connected to a second fixed bracket 219. A third threaded rod 220 is rotatably connected inside the second fixed bracket 219. A third knob 221 is fixedly connected to the top of the third threaded rod 220. A third connecting bracket 222 is rotatably connected to the outside of the third threaded rod 220. The third connecting bracket 222 is slidably connected to the second fixed bracket 219. Inside the bracket 219, a pressure roller 223 is rotatably connected to the inner side of the third connecting bracket 222. The pressure roller 223 contacts the upper surface of the woven bag to press and support it, further preventing wrinkles that could affect the sewing device 24's operation for stitching. The third connecting bracket 222 has a groove at a relative position to the third threaded rod 220. The third threaded rod 220 is rotatably connected inside the groove, which restricts its rotation, preventing it from moving with the third connecting bracket 222 and affecting the contact between the pressure roller 223 and the woven bag.
[0023] Please see Figure 1 , Figure 6 - Figure 7In this embodiment, the conveying mechanism includes a first motor 31, which is fixedly connected to the right side of the device body 1. A first conveyor wheel 32 is fixedly connected to the output end of the first motor 31 and rotatably connected inside the device body 1. A first conveyor belt 33 is driven to the outside of the first conveyor wheel 32. A second motor 34 is fixedly connected to the front of the device body 1. A second conveyor wheel 35 is fixedly connected to the output end of the second motor 34 and rotatably connected to the outside of the second conveyor wheel 35. A second conveyor belt 36 is driven to the outside of the second conveyor wheel 35. A third fixed bracket 37 is fixedly connected to the top of the device body 1. A second telescopic rod 38 is fixedly connected to the inner side of the third fixed bracket 37. A sliding rack 39 is fixedly connected to the top of the second telescopic rod 38 and slidably connected inside the third fixed bracket 37. A fixed gear 310 meshes with the outside of the sliding rack 39. The internal fixed connection of the 0 is a rotating shaft 311, which is rotatably connected to the inside of the third fixed bracket 37. The external fixed connection of the rotating shaft 311 is a connecting rod 312, and the internal connection of the connecting rod 312 is a second conveying roller body 313. The rotation of the rotating shaft 311 drives the second conveying roller body 313 to contact the cut snake skin bag, thereby driving the snake skin bag to move towards the second conveyor belt 36. The snake skin bag is conveyed at a stable speed and then sewn by the sewing device body 24. The third fixed bracket 37 has a groove at the relative position of the sliding rack 39. The sliding rack 39 is slidably connected inside the groove. The groove restricts the sliding of the sliding rack 39, so that the sliding rack 39 slides linearly inside the third fixed bracket 37, preventing the sliding rack 39 from tilting. Thus, the sliding rack 39 and the fixed gear 310 are stably engaged, driving the rotating shaft 311 to rotate.
[0024] During operation, the first knob 22 is rotated according to actual needs, which drives the first threaded rod 21 to rotate. The rotation of the first threaded rod 21 causes the sliding seat 23 to slide inside the main body 1 of the device, thereby adjusting the position of the sliding seat 23. Then, according to the required thickness of the burlap sack, the second knob 26 is rotated, which drives the second threaded rod 25 to rotate. The rotation of the second threaded rod 25 causes the first connecting bracket 27 to slide inside the first fixed housing 224, thereby adjusting the position of the upper guide plate 28 and the guide wheel assembly body 210. In subsequent operations, the burlap sack material is rolled and stuffed inside the first fixed bracket 211. The first conveying roller body 218 operates, conveying the burlap sack towards the first conveyor belt 33. The first motor 31 operates, further ensuring the stable conveying of the burlap sack. When the required length is reached, the first telescopic rod 212 operates, causing the second connecting bracket 213 to move downwards. When the bag moves downward, the pressure plate 214 first contacts the woven bag and presses it down. Then, the cutting scissors 216 cuts the bag. After cutting, the second connecting bracket 213 rises. At this time, the second telescopic rod 38 works, driving the sliding rack 39 to move. When the sliding rack 39 slides, it cooperates with the fixed gear 310 to drive the rotating shaft 311 to rotate. When the rotating shaft 311 rotates, it drives the connecting rod 312 and the second conveying roller body 313 to contact the woven bag. At this time, the second conveying roller body 313 works, driving the woven bag to be conveyed to the second conveyor belt 36. Then, the second motor 34 works to drive the second conveying wheel 35 to rotate, so that the woven bag is conveyed to the sliding seat 23. When the woven bag is conveyed to the sliding seat 23, the guide wheel group body 210 initially folds the edge of the woven bag to be sewn. Then, the upper guide plate 28 and the lower guide plate 29 cooperate to fold it further. At this time, the woven bag continues to move, and the sewing device body 24 works to sew it.
[0025] By following the steps above, the distance between the upper guide plate 28 and the lower guide plate 29 is adjusted according to the thickness of the woven bag, thus solving the problem in the prior art where the opening and position of the folding plate are relatively fixed, and the folding guide plate needs to be replaced when producing woven bags of different thicknesses.
