Description

Technical Field

[0001] The utility model relates to the technical field of valve bag processing, in particular to a cutting device with a positioning structure. Background Art

[0002] Valve bags, commonly known as paste-bottom bags, are internationally popular packaging bags. They are fed from the top or bottom valve port, and use special filling equipment. After filling the materials, they are packed into cubes. The stacking is neat and beautiful, and they are environmentally friendly bags. Valve bags can be divided into: PP valve bags, PE valve bags, paper-plastic composite valve bags, kraft paper valve bags, and multi-layer kraft paper valve bags according to their materials. PP valve bags are made of polypropylene woven cloth with upper or lower valve ports, which can improve packaging efficiency compared to ordinary PP woven bags; PE valve bags are made of polyethylene woven cloth valve ports; paper-plastic composite valve bags are made of plastic woven bags (referred to as cloth) as the base material, and are made by casting method (cloth / film composite is two-in-one, cloth / film / paper composite is three-in-one); the material of kraft paper valve bags is mainly kraft paper, of which kraft paper is divided into imported kraft paper and domestic kraft paper. When the valve bags are processed, they can be processed by cutting devices.

[0003] At present, when processing valve bag raw materials on the market, the valve bag raw materials can be cut and processed by a subsequent cutting device. In actual use, when the valve bag raw materials need to be cut and processed by a cutting device, the valve bag raw materials are usually placed directly on a workbench, and then the valve bag raw materials are cut by a subsequent cutting mechanism. When the valve bag raw materials are subjected to the force of the cutting knife during cutting, the position of the valve bag raw materials on the workbench is prone to shift, thereby affecting the cutting quality of the valve bag raw materials.

[0024] In a preferred embodiment, one end of the positioning rod 11 away from the extrusion block 10 passes through one side of the outer wall of the rotating block 4 and the positioning rod 11 is slidably connected to the rotating block 4. A positioning groove 12 is provided on the outer wall of the fixed block 3, and one end of the positioning rod 11 is slidably connected to the positioning groove 12. When the positioning rod 11 moves, the positioning rod 11 will move inside the groove 5, and at the same time, one end of the positioning rod 11 will move inside the positioning groove 12.

[0025] In a preferred embodiment, a spring 13 is provided between the outer wall of the movable block 7 and the groove 5, an adjusting groove 14 is opened on the top of the fixed block 3, a rotating rod 15 is rotatably connected inside the adjusting groove 14, one end of the rotating rod 15 passes through the outer wall of the fixed block 3 and the rotating rod 15 is fixedly connected to the rotating block 4, when the rotating block 4 moves, the rotating block 4 can drive the rotating rod 15 to move, so that the rotating rod 15 moves inside the adjusting groove 14.

[0026] In a preferred embodiment, the outer wall of the rotating rod 15 is fixedly connected to a limiting plate 16, and the top of the workbench 1 is fixedly connected to a support plate 17. A movable plate 18 is provided on the top of the support plate 17. A movable groove 19 is provided at the bottom of the movable plate 18. The support plate 17 is slidably connected to the movable groove 19. When the movable plate 18 moves, the movable plate 18 can drive the movable groove 19 to move, so that the support plate 17 can slide inside the movable groove 19.

[0027] The working principle of the utility model is as follows: when the device is used and the position of the raw material needs to be fixed, the pressing rod 8 is pressed to make the pressing rod 8 slide inside the groove 5, and at the same time, the pressing rod 8 will drive the movable block 7 to move, so that the movable block 7 slides inside the groove 5, and the movable block 7 slides on the outer wall of the fixed rod 6 at the same time. At the same time, the movable block 7 can squeeze the spring 13, and the movable block 7 drives the extrusion groove 9 to move at the same time, so that the extrusion block 10 can slide inside the extrusion groove 9, so that the subsequent movable block 7 can drive the positioning rod 11 to move through the extrusion groove 9 and the extrusion block 10, so that the positioning rod 11 slides inside the groove 5, and at the same time, one end of the positioning rod 11 can be separated from the positioning groove 12. When one end of the positioning rod 11 is completely separated from the positioning groove 12, the rotating block 4 is rotated at this time, and the rotating block 4 drives the limit plate 16 to move through the rotating rod 15, so that the limit plate 16 The adjusting groove 14 moves in a circular motion. When the limit plate 16 reaches the appropriate position, the rotation of the rotating block 4 is stopped and the pressing rod 8 is released. The elastic force of the spring 13 will make the movable block 7 return to the initial position, and then the movable block 7 drives the extrusion block 10 to move through the extrusion groove 9, and the extrusion block 10 drives the positioning rod 11 to move, so that one end of the positioning rod 11 enters into another positioning groove 12, so that the position of the subsequent rotating block 4 is fixed, and then the position of the limit plate 16 is convenient to fix. At this time, the raw material is placed on the workbench 1 so that the raw material is located on one side of the extrusion plate and the bottom end of the cutting device 2. The pressing rod 8 is pressed and the rotating block 4 is rotated to return to the initial position, so that the limiting plate 16 can squeeze and fix the raw material. At this time, the pressing rod 8 is released to allow one end of the positioning rod 11 to enter into the initial positioning groove 12, so that there will be no position movement problem in the subsequent raw material processing.

[0028] See also Figure 1 and Figure 3 The utility model provides a technical solution: a locking groove 20 is provided on the outer wall of the support plate 17, and a threaded rod 21 is provided on the outer wall of the movable plate 18. One end of the threaded rod 21 passes through the interior of the movable groove 19 and the threaded rod 21 is connected to the movable plate 18 through a thread. When the threaded rod 21 moves, the threaded rod 21 can move with the movable plate 18 through the thread, so that one end of the threaded rod 21 can be separated from the locking groove 20.

[0029] In a preferred embodiment, one end of the threaded rod 21 is slidably connected to the locking groove 20, and the top of the movable plate 18 is fixedly connected to the bottom end of the cutting device 2. When the movable block 7 moves, the movable block 7 can drive the extrusion block 10 to move through the extrusion groove 9, and the movable block 7 can squeeze the spring 13 at the same time.

[0030] The working principle of the utility model is as follows: when the device is used and the height of the cutting device 2 needs to be adjusted according to processing requirements, the threaded rod 21 is rotated at this time to make the threaded rod 21 and the movable plate 18 move through the thread, so that one end of the threaded rod 21 slowly moves inside the engaging groove 20, so that one end of the threaded rod 21 can be moved out from the engaging groove 20. At this time, the movable plate 18 is pulled to move, so that the movable plate 18 can drive the movable groove 19 to move, so that the support plate 17 can slide inside the movable groove 19. When the height of the movable plate 18 reaches a suitable position, the engaging groove 20 on the outer wall of the support plate 17 is located on one side of the threaded rod 21. The threaded rod 21 is reversed to make one end of the threaded rod 21 enter the engaging groove 20, so that the position of the cutting device 2 can be conveniently adaptively adjusted.
