DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 , 2, 3 and 5, a packaging bag material cutting assembly comprises a leg 1; a workbench body 11 is installed on the top of the leg 1; a motor 12 is installed at the end of the workbench body 11; a belt 13 is provided at the output of the motor 12; a storage box 14 is fixedly connected to the top of the leg 1; the storage box 14 is arranged at the bottom of the belt 13; a bevel gear 15 is fixedly connected to the middle of the output end of the motor 12; two groups of connecting blocks 16 are fixedly connected to the outer wall of the leg 1; a reciprocating screw 17 is rotatably connected to the middle of the connecting block 16; the top of the reciprocating screw 17 is meshed with the bevel gear 15 The reciprocating screw 17 is threadedly connected with a slide bar 18 in the middle; the slide bar 18 is slidably arranged in the middle of the leg 1 and the storage box 14; two sets of pressing plates 19 are fixedly connected in the middle of the slide bar 18; when working, the staff needs to install the leg 1 in the working area, and then place the tubular material to be cut on the top of the workbench body 11, and after fixing it, turn on the switch of the workbench body 11, so that the tool in the middle of the workbench body 11 cuts the tubular material, and the motor 12 is arranged at the end of the workbench body 11, so that the workbench body 11 cuts When more residues are generated during the mowing process, the staff can turn on the motor 12 switch, so that the output end of the motor 12 will synchronously drive the belt 13 to rotate when working, so that the residues dropped on the middle of the belt 13 will be transferred to the inside of the storage box 14. Because a bevel gear 15 is provided in the middle of the output end of the motor 12, when the motor 12 is working, the reciprocating screw 17 meshing with the bevel gear 15 is matched, so that the reciprocating screw 17 is rotated in the middle of the two sets of connecting blocks 16, and the sliding rod 18 is reciprocated up and down in the middle of the reciprocating screw 17. The two sets of pressing plates 19 will move, and the residues accumulated inside the storage box 14 will be compacted downwards, and this will be repeated. This step is carried out in conjunction with a belt 13 provided in the middle of the workbench body 11 to lift the workbench body 11. When cutting tubular materials, a lot of residues are accumulated in the middle, which causes pollution to the middle of the workbench body 11. At the same time, the storage box 14 can collect polyethylene residues to reduce the waste of production materials. In conjunction with two sets of pressing plates 19 that can be pressed downwards, the residue materials in the middle of the storage box 14 can be compacted to increase the storage space of the storage box 14.

[0025] like Figure 3 and 5As shown, the top of the pressing plate 19 is fixedly connected to the elastic cloth 2; the bottom of the pressing plate 19 is fixedly connected to the first spring 21; the end of the first spring 21 is fixedly connected to the pressing block 22; the middle of the pressing block 22 is fixedly connected to the sliding column 23; the sliding column 23 is slidingly arranged in the middle of the pressing plate 19; the sliding column 23 is arranged inside the first spring 21; when working, by arranging the first spring 21 in the middle of the pressing plate 19, when the pressing plate 19 moves downward under the action of the sliding rod 18, the middle of the pressing block 22 will contact the material first, and after contact, continue to squeeze the sliding column 23 to move upward, at this time, the middle of the first spring 21 will be squeezed and shortened, and at the same time The slide column 23 will slide so that the top of the slide column 23 presses against the middle of the elastic cloth 2, so that the middle of the elastic cloth 2 is raised and tilted, and the plastic residue accumulated in the middle of the elastic cloth 2 is transferred to the inside of the storage box 14. This step cooperates with the two groups of pressing blocks 22 raised at the bottom of the pressing plate 19 to further compact the plastic residue material inside the storage box 14, and cooperates with the slide column 23 slidably arranged in the middle of the pressing plate 19, so that the elastic cloth 2 raised in the middle will transfer the residue on its top to the inside of the storage box 14, reducing the problem that the top of the pressing plate 19 is set as a plane, resulting in a lot of residue accumulated on its top and requiring manual cleaning by staff.

[0026] like Figure 1 , 2 As shown in Figure 4, the end of the support leg 1 is fixedly connected to a support rod 3; the middle of the support rod 3 is fixedly connected to two sets of kits 31; the end of the kit 31 is fixedly connected to a second spring 32; the end of the second spring 32 is fixedly connected to a scraper 33; the middle of the scraper 33 is inclined; the middle of the scraper 33 is in contact with the belt 13; when working, by arranging the support rod 3 at the end of the support leg 1, when the belt 13 works in the middle of the workbench body 11, the friction between the middle of the belt 13 and the scraper 33 will cause the scraper 33 to tilt downward, and the second spring 32 will be fixedly connected to the end of the second spring 32 ... The middle part of the scraper 33 is pulled and deformed, so that the scraper 33 can scrape and clean the residue attached to the surface of the belt 13, and after the belt 13 stops moving, the scraper 33 can shake and transfer the residue cleaned and accumulated in the middle part of the belt 13 in cooperation with the second spring 32 with elastic force. This step uses the contact surface between the scraper 33 and the middle part of the belt 13 to improve the cleanliness of the middle part of the motor 12 and reduce the problem of more residues accumulated in the middle part of the motor 12 after long-term use, which makes it difficult to clean the middle part later. The second spring 32 can improve the stability of the contact between the scraper 33 and the middle part of the motor 12.

[0027] like Figure 5As shown, a receiving groove 4 is provided on the top of the pressure plate 19; a top block 41 is fixedly connected to the top of the sliding column 23; the top block 41 is arranged at the bottom of the elastic cloth 2; when working, by arranging a circular top block 41 on the top of the sliding column 23, when the sliding column 23 moves upward, the top of the top block 41 will contact the middle part of the elastic cloth 2 first, and push the middle part of the elastic cloth 2, and then when it needs to be stored, the top block 41 can be stuck in the storage groove 4 for reset. This step cooperates with the top block 41 to increase the friction when contacting the inner wall of the elastic cloth 2, and at the same time can reduce the problem of large wear caused by the sliding column 23 directly being squeezed and contacted with the middle part of the elastic cloth 2, and at the same time can limit the reset distance of the sliding column 23 to reduce the problem of the sliding column 23 retracting deeply downward.

[0028] like Figure 3 and 5 As shown, a connecting rod 5 is fixedly connected to the middle of the pressure block 22; a plurality of counterweight blocks 51 are fixedly connected to the middle of the connecting rod 5; the counterweight blocks 51 are arranged in a linear array in the middle of the connecting rod 5; when working, by arranging a connecting rod 5 in the middle of the pressure block 22, the synchronization of the two groups of pressure blocks 22 during movement can be improved in cooperation with the connecting rod 5. This step can reduce the problem of unequal heights of the two groups of pressure blocks 22 during use in cooperation with the connecting rod 5, and at the same time, the downward gravity of multiple groups of counterweight blocks 51 can improve the stability of the reset of the top block 41.

[0029] like Figure 2 As shown, the inner wall of the storage box 14 is fixedly connected to the limiting member 6; the slide bar 18 is slidably arranged on the inner wall of the storage box 14; when working, by setting the limiting member 6 on the inner wall of the storage box 14, the slide bar 18 will move at the inner wall of the limiting member 6. This step cooperates with the limiting member 6 to improve the stability of the slide bar 18 when it moves inside the storage box 14, and reduce the problem of bending and deformation of the middle part of the slide bar 18 when it moves during use.

[0030] like Figure 3 As shown, a baffle 7 is fixedly connected to the top of the leg 1; the middle part of the baffle 7 is arc-shaped; when working, by arranging the baffle 7 on the top of the leg 1, the arc-shaped baffle 7 will shield the bevel gear 15 and the top of the connecting block 16. This step cooperates with the baffle 7 to reduce the problem of some foreign impurities falling directly on the top of the bevel gear 15 or the connecting block 16, resulting in greater resistance when the two are meshed.

[0031] The working principle is as follows: after the support leg 1 is installed in the working area, the tubular material to be cut is placed on the top of the workbench body 11, and after it is fixed, the switch of the workbench body 11 is turned on, so that the tool in the middle of the workbench body 11 cuts the tubular material. By arranging a motor 12 at the end of the workbench body 11, when a lot of residue is generated during the cutting process of the workbench body 11, the staff can turn on the switch of the motor 12, so that the output end of the motor 12 will synchronously drive the belt 13 to rotate during work, so that the residue dropped on the middle of the belt 13 will be transferred to the inside of the storage box 14. Because a bevel gear 15 is arranged in the middle of the output end of the motor 12, When the motor 12 is working, it cooperates with the reciprocating screw 17 meshing with the bevel gear 15, so that the reciprocating screw 17 will rotate in the middle of the two sets of connecting blocks 16, and cooperates with the thread in the middle, so that the slide bar 18 will reciprocate up and down in the middle of the reciprocating screw 17, and the two sets of pressing plates 19 will compact the residue accumulated inside the storage box 14 downward, and repeat this process. By arranging a first spring 21 in the middle of the pressing plate 19, when the pressing plate 19 moves downward under the action of the slide bar 18, the middle of the pressing block 22 will contact the material first, and after the contact, it will continue to squeeze the slide column 23 to move upward, at this time, the middle of the first spring 21 will be squeezed and shortened, and at the same time The slide column 23 will slide, so that the top of the slide column 23 will press against the middle part of the elastic cloth 2, so that the middle part of the elastic cloth 2 is convex and tilted, and the plastic residue accumulated in the middle part of the elastic cloth 2 is transferred to the inside of the storage box 14. By arranging a support rod 3 at the end of the leg 1, when the belt 13 works in the middle part of the workbench body 11, the scraper 33 will be tilted downward by the friction between the middle part of the belt 13 and the scraper 33, and the middle part of the second spring 32 will be pulled and deformed, so that the scraper 33 will scrape and clean the residue attached to the surface of the belt 13, and after the belt 13 stops moving, the second spring 32 with elastic force can clean the accumulated residue in the middle part of the scraper 33 To perform shaking transfer, a circular top block 41 is provided on the top of the sliding column 23, so that when the sliding column 23 moves upward, the top of the top block 41 will contact the middle part of the elastic cloth 2 first and push the middle part of the elastic cloth 2. Then, when it needs to be stored, the top block 41 can be clamped in the storage groove 4 for reset. A connecting rod 5 is provided in the middle of the pressure block 22, and the synchronization of the two groups of pressure blocks 22 during movement can be improved by cooperating with the connecting rod 5. A limiting member 6 is provided on the inner wall of the storage box 14, so that the sliding rod 18 will move on the inner wall of the limiting member 6. A baffle 7 is provided on the top of the leg 1, so that the arc-shaped baffle 7 will block the bevel gear 15 and the top of the connecting block 16.
