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] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The utility model provides a technical solution: an anti-winding film shredder, comprising a processing box 1, a connecting plate 20 and a cutting blade 21, characterized in that: a moving mechanism is arranged on the cutting blade 21, the moving mechanism comprises a moving plate 22, the moving plate 22 does not contact the inner wall of the fixed shell 25, so as to reduce the resistance of the moving plate 22 when it moves inside the fixed shell 25, the moving plate 22 and the connecting plate 20 are fixed by welding, a rotating groove 30 is provided at the front end of the moving plate 22, and an adapter block 28 is connected to the internal rotation of the rotating groove 30, and the cross sections of the adapter block 28 and the rotating groove 30 are both T-shaped, the adapter block 28 is fixed to the rear end of the threaded rod 23 by welding, the threaded rod 23 is threadedly connected to the fixed shell 25, and a rotating handle 24 is welded and fixed to the front end of the threaded rod 23, a groove 26 is provided at the front end of the processing box 1, the groove 26 is aligned with the connecting plate 20, a through groove 27 is provided on the groove 26, the through groove 27 is communicated with the inside of the processing box 1, and the fixed shell 25 is welded and fixed to the front end of the processing box 1;

[0025] During operation, through the structural design of the moving mechanism, when the cutting blade 21 is not needed, the cutting blade 21 is stored inside the fixed shell 25 to avoid affecting the normal operation inside the processing box 1, while also ensuring that the plastic film inside the processing box 1 will not be entangled on the cutting blade 21, and when the cutting blade 21 is needed, the cutting blade 21 is pushed into the processing box 1 through the moving plate 22 to cut the plastic film. When the wound plastic film inside the processing box 1 needs to be cut, the threaded rod 23 is first driven to rotate by rotating the rotating handle 24. The threaded rod 23 is threadedly connected to the fixed shell 25, so the threaded rod 23 will move toward the inside of the fixed shell 25, and the rear end of the threaded rod 23 and the moving plate 22 are rotated through the adapter block 28 and the rotating groove 30. The movable plate 22 is connected together, so the movable plate 22 will move in the fixed shell 25 under the push of the threaded rod 23 until the cutting blade 21 on the rear end of the movable plate 22 extends into the interior of the processing box 1. At this time, the cutting blade 21 can cut the plastic film inside the processing box 1. When the cutting is completed, only the rotating handle 24 needs to be turned again to move the cutting blade 21 away from the processing box 1 and move it back to the interior of the fixed shell 25 for storage, so as to avoid the plastic film inside the processing box 1 from being entangled on the cutting blade 21. The cutting blade 21 is provided with multiple groups, and the position of the groove 26 corresponds to the connecting plate 20 one by one and the size is slightly larger than the connecting plate 20, so that the connecting plate 20 can smoothly enter the groove 26. Similarly, the size of the through groove 27 is also slightly larger than the width of the cutting blade 21.

[0026] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6A rotating rod 39 is welded and fixed on the inner wall of the through slot 27, and a fixed plate 40 is rotatably connected to the rotating rod 39. A torsion spring 38 is sleeved on the top of the rotating rod 39. The torsion spring 38 is arranged inside the through slot 27. A mounting groove corresponding to the torsion spring 38 is opened inside the through slot 27 to facilitate the placement of the torsion spring 38. An extension column 29 is welded and fixed to the front end of the fixed shell 25. The inner wall of the extension column 29 is provided with a thread. The extension column 29 is threadedly connected to the threaded rod 23. Pulleys 34 are welded and fixed on both sides of the movable plate 22. The pulley 34 is slidably connected to the long slot 33. The long slot 33 is opened on the inner wall of the fixed shell 25.

[0027] During operation, through the structural design of the torsion spring 38, the rotating rod 39 and the fixed plate 40, the two sets of fixed plates 40 rotating on the through slot 27 block the through slot 27 to reduce the situation where the plastic film inside the processing box 1 enters the fixed shell 25 through the through slot 27, and the rotating rod 39 is sleeved with a torsion spring 38, which can automatically close when the cutting blade 21 retreats into the fixed shell 25. An extension column 29 is fixed on the front end of the fixed shell 25. The extension column 29 is used to extend the part where the fixed shell 25 is threadedly connected to the threaded rod 23 to facilitate the connection between the threaded rod 23 and the fixed shell 25. Pulleys 34 are fixed on the left and right sides of the movable plate 22. When the movable plate 22 moves, the pulley 34 will slide on the long slot 33 to provide support for the left and right sides of the movable plate 22.

[0028] See also Figure 2 , Figure 3 and Figure 4 The top and bottom ends of the movable plate 22 are both welded with sliders 36, which are slidably connected to the inside of the slide groove 35. The slide groove 35 and the slider 36 are both provided with multiple groups. The slide groove 35 is opened on the inner wall of the fixed shell 25. The rear end of the movable plate 22 is welded with a spring 32, and the rear end of the spring 32 is welded and fixed in the circular groove 31. The circular groove 31 is opened at the front end of the processing box 1. The top of the fixed shell 25 is provided with a rectangular groove 37, which is provided with multiple groups. The rectangular groove 37 is located directly above the cutting blade 21;

[0029] During operation, sliders 36 are fixed on the top and bottom of the movable plate 22. The sliding of the sliders 36 on the slide grooves 35 ensures the normal movement of the movable plate 22 in the fixed shell 25. At the same time, the stability of the movable plate 22 during movement is also guaranteed, reducing the shaking of the cutting blade 21 during operation. Multiple groups of springs 32 are also fixed on the movable plate 22, and the springs 32 are located between two adjacent groups of cutting blades 21. As the movable plate 22 continues to move inside the fixed shell 25, the springs 32 will gradually be compressed and the resistance to turning the rotating handle 24 will become larger, so as to remind the operator to avoid turning the rotating handle 24 too quickly, which may cause the movable plate 22 to abut against the processing box 1. Multiple groups of rectangular grooves 37 are also provided on the top of the fixed shell 25. The rectangular grooves 37 also correspond to the cutting blades 21 one by one, so as to facilitate the replacement of the cutting blades 21 fixed on the connecting plate 20 through the rectangular grooves 37.

[0030] Working principle: An anti-winding film shredder in the prior art, since the cutting blade and the shredding blade are both located inside the processing box, when the shredding blade is shredding the plastic film, it is inevitable that some plastic film will be entangled and attached to the cutting blade and the connecting plate used to fix the cutting blade, affecting the normal operation of the cutting blade, and it is also necessary to additionally clean the plastic film on the cutting blade and the connecting plate. The anti-winding film shredder in this case is designed with a moving mechanism. When the cutting blade 21 is not needed, the cutting blade 21 is stored inside the fixed shell 25 to avoid affecting the normal operation inside the processing box 1, while also ensuring that the plastic film inside the processing box 1 will not be entangled on the cutting blade 21. When the cutting blade 21 is needed, the cutting blade 21 is pushed into the processing box 1 through the moving plate 22 to cut the plastic film. When it is necessary to cut the entangled plastic film inside the processing box 1, the threaded rod is first driven by rotating the rotating handle 24. 23 rotates, the threaded rod 23 is threadedly connected to the fixed shell 25, so the threaded rod 23 will move toward the inside of the fixed shell 25, and the rear end of the threaded rod 23 is rotatably connected to the movable plate 22 through the adapter block 28 and the rotating groove 30, so the movable plate 22 will move in the fixed shell 25 under the push of the threaded rod 23 until the cutting blade 21 on the rear end of the movable plate 22 extends into the interior of the processing box 1, at this time, the cutting blade 21 can cut the plastic film inside the processing box 1, and when the cutting is completed, only the rotating handle 24 needs to be rotated again, so that the cutting blade 21 can be moved away from the processing box 1 and moved back to the interior of the fixed shell 25 for storage, so as to avoid the plastic film inside the processing box 1 from being wrapped around the cutting blade 21, wherein the cutting blade 21 is provided with multiple groups, and the position of the groove 26 is corresponding to the connecting plate 20 one by one and the size is slightly larger than the connecting plate 20, so that the connecting plate 20 can smoothly enter the groove 26, and the size of the through groove 27 is also slightly larger than the width of the cutting blade 21.
