[0014] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.
[0015] The structure of this utility model will now be described in detail with reference to the accompanying drawings.
[0016] Please see Figures 1 to 4 This utility model provides an automatic cutting and sewing machine for woven bags, comprising: a first support frame 1, with a placement plate 2 mounted on one side of the first support frame 1; a placement roller 3 mounted on the first support frame 1 for placing woven bags; a cutting and sewing adjustment component mounted on the first support frame 1 for sealing and opening the woven bags; a pressing component mounted on the cutting and sewing adjustment component; and a driving component mounted on the first support frame 1. The driving component includes an electric push rod 4 mounted on the first support frame 1, and a sleeve 5 connected to the cutting and sewing adjustment component is mounted on the output end of the electric push rod 4.
[0017] Using the above scheme: In the woven bag cutting operation, first install the woven bag on the placement roller 3, then pull the woven bag onto the placement plate 2. Adjust the distance between the cutting adjustment parts according to the required processing length of the woven bag. After the adjustment is completed, the output end of the electric push rod 4 pushes the sleeve 5 to produce displacement. The longitudinal movement of the sleeve 5 drives the cutting adjustment parts to move synchronously, thereby sealing and opening both sides of the woven bag. The pressing part is used to prevent the woven bag from shifting during the processing, thus completing the sealing and opening operation of the woven bag.
[0018] Furthermore, the slit adjustment component includes a first slide rail 6 formed on the first support frame 1; A first slider 7 is slidably connected inside the first slide rail 6, and a first fixing plate 8 is fixedly connected to both the first slider 7 and the first support frame 1.
[0019] Furthermore, each of the first fixed plates 8 is provided with a second slide rail 9; a second slider 10 is slidably connected in the second slide rail 9; a bearing plate 11 is fixedly connected to the lower side of each of the second sliders 10, a cutting machine 12 is installed on one of the bearing plates 11, and a sewing machine 13 is installed on the other bearing plate 11.
[0020] Furthermore, a guide rod 14 is slidably connected inside the sleeve 5; one end of the guide rod 14 is fixedly connected to one of the second sliders 10, and the other end of the guide rod 14 is slidably connected to another second slider 10; a groove 15 is provided on one of the first fixing plates 8, and the groove 15 is located on the lower side of the cutting machine 12.
[0021] Furthermore, a toothed plate 16 is fixedly connected to the back of the first slider 7; a first motor 17 is installed on the back of the first support frame 1, and a first gear 18 is installed at the output end of the first motor 17, and the first gear 18 meshes with the toothed plate 16.
[0022] Using the above scheme: In use, the woven bag is placed on the placement plate 2, with the side of the woven bag that needs to be cut placed in the cutting groove 15. The output end of the first motor 17 is rotated, which in turn drives the first gear 18 on it to rotate synchronously. Since the first gear 18 meshes with the toothed plate 16, when the first gear 18 rotates, it drives the toothed plate 16 to move the first slider 7 within the first slide rail 6. When the first slider 7 moves, it drives the supporting plate 11 on it away from the supporting plate 11 on the first support frame 1. At this time, the guide rod 14 will move between the sleeve 5 and one of the second sliders 10. The sliding motion improves the stability of the first slider 7 during movement. Based on the required processing length of the woven bag, the distance between the cutting machine 12 and the sewing machine 13 is adjusted. After the adjustment is completed, the output end of the electric push rod 4 pushes the sleeve 5 to produce displacement. The longitudinal movement of the sleeve 5 will drive the guide rod 14 to move the two second sliders 10 in the second slide rail 9, which in turn drives the bearing plate 11 on it to move. When the bearing plate 11 moves, it will drive the cutting machine 12 and the sewing machine 13 on it to move synchronously. During the movement of the cutting machine 12 and the sewing machine 13, they will work on their own to seal and open the woven bag.
[0023] Furthermore, the pressing component includes: a first connecting rod 19 fixedly connected to two bearing plates 11, and a second fixing plate 20 fixedly connected to one end of the first connecting rod 19.
[0024] Furthermore, two sets of symmetrically arranged telescopic rods 21 are fixedly connected to the lower side of the second fixing plate 20; a fixing frame 22 is installed at the extended end of the telescopic rod 21; a plurality of springs 23 are installed between the fixing frame 22 and the second fixing plate 20, and a pressing wheel 24 is rotatably connected to the fixing frame 22.
[0025] Using the above solution: When in use, after the woven bag is placed on the placement plate 2, the force generated by the compression of the spring 23 pushes the fixing frame 22, causing the fixing frame 22 to drive the telescopic rod 21 to extend, thereby making the pressing wheel 24 contact the woven bag. When the second slider 10 moves, it will pull the support plate 11. The support plate 11 will drive the first connecting rod 19 and the first fixing plate 8 to move synchronously, causing the pressing wheel 24 to rotate on the surface of the woven bag. The pressure applied by the pressing wheel 24 can prevent the woven bag from shifting during the opening and sealing process.
[0026] The working principle of this utility model: In the woven bag cutting operation, the woven bag is first installed on the placement roller 3, and then pulled onto the placement plate 2 so that the side of the woven bag to be cut is placed into the cutting groove 15. The force generated by the compression of the spring 23 pushes the fixing frame 22, causing the fixing frame 22 to drive the telescopic rod 21 to extend, thereby making the pressing wheel 24 contact the woven bag. The output end of the first motor 17 rotates, thereby driving the first gear 18 on it to rotate synchronously. Since the first gear 18 meshes with the toothed plate 16, when the first gear 18 rotates, it drives the toothed plate 16 to move the first slider 7 within the first slide rail 6. When the first slider 7 moves, it moves the bearing plate 11 on it away from the bearing plate 11 on the first support frame 1. At this time, the guide rod 14 will slide between the sleeve 5 and one of the second sliders 10, thereby improving the movement of the first slider 7. The stability during movement is adjusted according to the required processing length of the woven bag. The distance between the cutting machine 12 and the sewing machine 13 is adjusted. After the adjustment is completed, the output end of the electric push rod 4 pushes the sleeve 5 to produce displacement. The longitudinal movement of the sleeve 5 will drive the guide rod 14 to move the two second sliders 10 in the second slide 9 and drive the bearing plate 11 on them to move. When the bearing plate 11 moves, it will drive the cutting machine 12 and the sewing machine 13 on it to move synchronously. During the movement of the cutting machine 12 and the sewing machine 13, they will work on their own to seal and open the woven bag. When the second slider 10 moves, it will pull the bearing plate 11. The bearing plate 11 will drive the first connecting rod 19 and the first fixed plate 8 to move synchronously, causing the pressing wheel 24 to rotate on the surface of the woven bag. The pressure applied by the pressing wheel 24 can prevent the woven bag from deviating during the opening and sealing process.
