[0002] Woven bags are packaging products made from chemical plastic raw materials such as polyethylene (PE) or polypropylene (PP). The production process mainly includes extruding and stretching the plastic raw materials into flat filaments, then weaving the warp and weft yarns into woven fabric using a weaving machine, and finally making bags through printing, cutting, and sewing processes.

[0003] In the woven bag cutting process, external forces often cause slight displacement of the material, which directly results in uneven cut edges. At the same time, the inherent elasticity of the woven bag material causes it to stretch and deform during the cutting process due to external forces.

They are only for the convenience of describing the embodiments and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, this embodiment of the invention proposes a cutting tool for woven bags, including a flattening assembly 1. The flattening assembly 1 includes a movable frame 11, a first rotating shaft 12, a first fixed frame 13, a first sliding groove 14, a connecting frame 15, a support platform 16, a sliding column 17, a second spring 18, a limiting plate 19, a limiting shaft 110, a second fixed frame 111, a second rotating shaft 112, a connecting column 113, a pressing frame 114, a third sliding groove 115, a movable rod 116, a rotating base 117, a first spring 118, a pressure plate 119, a guide plate 1110, and a second sliding groove 1111.

[0031] In this embodiment of the invention, a pressure plate 119 is provided on one side of the movable frame 11. The pressure plate 119 and the movable frame 11 are connected by multiple sets of first springs 118. The pressure plate 119 can move in all directions relative to the movable frame 11. A guide plate 1110 is connected to the lower part of the pressure plate 119. There is a gap between the guide plate 1110 and the pressure plate 119. During use, the woven bag to be processed needs to pass through the guide plate 1110 and the inside of the pressure plate 119. Rotating bases 117 are fixed on both sides of the top of the pressure plate 119. A movable rod 116 is movably provided inside the rotating base 117. The rod 116 is externally equipped with a pressing frame 114. Each pressing frame 114 has a third sliding groove 115 inside. The top of the movable rod 116 passes through the third sliding groove 115 so that it can slide along the third sliding groove 115. The other end of the rotating base 117 is movably disposed inside the third sliding groove 115. One end of the pressing frame 114 is connected to a connecting post 113. The connecting post 113 is fixedly connected to the connecting block 24 in the cutting assembly 2. The connecting block 24 is fixed to the outside of the cutting blade 23. Therefore, when the cutting blade 23 moves downward, it can drive the connecting post 113 to move downward.

[0032] Both sides of the movable frame 11 are connected to a first fixed frame 13. Each first fixed frame 13 has a first sliding groove 14 inside. The two ends of the movable frame 11 pass through the first sliding groove 14 and are connected to one side of the first rotating shaft 12. When the first rotating shaft 12 moves, it can drive the movable frame 11 to move along the first sliding groove 14. The guide plate 1110 is fixed inside the multiple sets of first fixed frames 13. A second fixed frame 111 is fixedly connected to one side of the first fixed frame 13. The second fixed frame 111 also has a second sliding groove 1111 inside. The connecting column 113 is movably disposed inside the second sliding groove 1111. The other side of the connecting column 113 is connected to one end of the second rotating shaft 112. The second rotating shaft 112 and the first rotating shaft 12 are movably connected through the connecting frame 15.

[0033] When the cutting blade 23 moves downward, the connecting block 24 on the outside of the cutting blade 23 will drive the connecting column 113 fixed inside it to move downward synchronously. During the downward movement of the connecting column 113, it will drive the second rotating shaft 112 on one side to move downward along the second sliding groove 1111. The second rotating shaft 112 is rotatably connected to the first rotating shaft 12. The first rotating shaft 12 is pushed outward by the connecting frame 15, that is, the first rotating shaft 12 will move outward along the first sliding groove 14. During the movement of the first rotating shaft 12, the moving frame 11 fixed inside it will move together. The moving frame 11 will also push the pressure plate 119 at its front end to move outward. At the same time as the connecting column 113 moves downward, the pressing frame 114 on its side will press down. The movable rod 116 moves downward. Since the lower part of the movable rod 116 is movably connected to the top of the pressure plate 119 through the rotating base 117, the movable rod 116 can press the pressure plate 119 downward. Finally, the movable frame 11 can push the pressure plate 119 outward, and cooperate with the movable rod 116 on the upper part of the pressure plate 119 to press it. Since the pressure plate 119 and the movable frame 11 are connected by a spring, the pressure plate 119 can move diagonally downward. The woven bag to be cut is placed between the pressure plate 119 and the guide plate 1110. As the pressure plate 119 applies a diagonally downward pressure to the woven bag, the woven bag can be flattened during the cutting process, which can avoid the problem of inaccurate cutting size caused by the elastic deformation of the woven bag.

[0034] In the cutting and processing of woven bags, external forces can easily cause slight displacement of the material, directly resulting in uneven cutting edges. At the same time, the elasticity of the woven bag material itself will cause tensile deformation due to stress during the cutting process, resulting in deviations between the final cutting size and the preset target. These problems seriously affect the cutting quality and accuracy. Therefore, there is an urgent need to develop a dedicated woven bag cutting device to effectively solve the above technical problems. The present invention places the woven bag between the pressure plate 119 and the guide plate 1110. During the cutting process, the pressure plate 119 is used to stretch the woven bag obliquely, which can tighten the woven bag and prevent it from shifting. Ultimately, it can improve the state of the woven bag during the cutting process and improve the cutting quality of its edges.

[0035] A support platform 16 is fixedly connected to the side of the second fixed frame 111. A sliding column 17 is fixed to the top of the support platform 16. A second spring 18 is sleeved on the outside of the sliding column 17. A limit plate 19 is fixed to the top of the second spring 18, and the sliding column 17 passes through the inside of the limit plate 19. One side of the limit plate 19 is fixedly connected to the outside of the second rotating shaft 112. Therefore, when the second rotating shaft 112 moves downward along the second sliding groove 1111, the second rotating shaft 112 will drive the limit plate 19 to compress the second spring 18. The second spring 18 can buffer the movement of the second rotating shaft 112 and prevent the pressure plate 119 from damaging the woven bag due to the rapid movement of the connecting frame 15. A limit shaft 110 is provided at the top of the sliding column 17, which can restrict the movement of the limit plate 19.

[0036] like Figure 1 , Figure 2 and Figure 7 As shown in the figure, an embodiment of the present invention provides a cutting tool for cutting woven bags, including a cutting component 2. The cutting component 2 is fixed outside the flattening component 1. The cutting component 2 is used to drive the flattening component 1 to move and cut the woven bag.

[0037] The cutting assembly 2 includes an electric cylinder 21, a push rod 22, a cutting blade 23, a connecting block 24, a sliding frame 25, a sliding groove 26, a horizontal support 27, a vertical support 28, a buffer frame 29, and a third spring 210.

[0038] In this embodiment of the invention, a horizontal support 27 is fixedly connected to the outside of the electric cylinder 21. A push rod 22 passes through the inside of the horizontal support 27, and a cutting blade 23 is connected to the bottom of the push rod 22. The electric cylinder 21 drives the push rod 22 to move, thereby driving the cutting blade 23 to cut the woven bag. Multiple sets of connecting blocks 24 are fixedly connected to the outside of the cutting blade 23. The connecting blocks 24 are connected to the connecting column 113, so when the cutting blade 23 moves downward, it can drive the connecting column 113 to move synchronously. Sliding frames are fixedly connected to both sides of the top of the cutting blade 23. 25. A vertical support 28 is connected to the outside of the sliding frame 25. The vertical support 28 is fixed to the lower part of the horizontal support 27. A sliding groove 26 is opened inside the vertical support 28. The sliding frame 25 is movably connected in the sliding groove 26. When the cutting blade 23 moves up and down, it can drive the sliding frame 25 to move along the sliding groove 26. A buffer frame 29 is connected to the lower part of the cutting blade 23. The buffer frame 29 is connected to the horizontal support 27 through a third spring 210. The buffer frame 29 can buffer the shaking that occurs during the cutting of the woven bag, thereby improving the quality of the woven bag cutting.

[0039] like Figure 1 and Figure 8As shown in the figure, an embodiment of the present invention provides a cutting tool for woven bags, including a conveying component 3. The conveying component 3 is disposed outside the flattening component 1 and is used to convey the woven bags to be processed.

[0040] The conveying assembly 3 includes a side frame 31, a rolling shaft 32, a tray 33, a servo motor 34, and a base 35.

[0041] In this embodiment of the invention, a rolling shaft 32 is connected inside the side frame 31, and a servo motor 34 is provided at the lower part of the side frame 31. The servo motor 34 can drive the rolling shaft 32 to rotate through the transmission component. The woven bag is placed on the upper part of the rolling shaft 32. With the transmission of the rolling shaft 32, the woven bag can be conveyed to the position of the cutting component 2 for cutting. A tray 33 is provided at the lower part of the side frame 31. One side of the tray 33 is fixedly connected to the servo motor 34. A base 35 is connected at the lower part of the tray 33. The base 35 is used to support the operation of the conveying component 3.
