Therefore, they should not be construed as limitations on this utility model.

[0026] like Figure 1 As shown, a paper product shredding device includes an outer box 1, which is a hollow U-shaped box. A drive shaft 2, which is a circular shaft, is arranged in a mirror-like staggered manner on the side of the outer box 1. A connecting plate 3, which is a trapezoidal plate, is fixedly installed at equal intervals on both sides of the inner side of the outer box 1. A limiting plate 4, which is a circular ring plate, is movably sleeved on the side of the drive shaft 2 corresponding to the position of the connecting plate 3. A crushing plate 5, which is a saw blade-shaped circular ring plate, is movably sleeved at equal intervals on the side of the drive shaft 2 and is positioned between the connecting plates 3. An adjustable guiding mechanism 6 is provided on the upper side of the outer box 1. A cleaning mechanism 7, which can clean the crushing plate 5, is provided on the side of the connecting plate 3 corresponding to the side of the crushing plate 5.

[0027] Specifically, the guide mechanism 6 can be adjusted according to the amount of material, so that the paper products slide to the crushing plate 5 for crushing. The cleaning mechanism 7 can perform a cleaning operation while the crushing plate 5 is crushing.

[0028] like Figure 1 and Figure 3 As shown, the guiding mechanism 6 includes a fixed shaft 61 symmetrically fixedly installed inside the outer casing 1. The fixed shaft 61 is a circular shaft. A guide plate 62 is movably sleeved on the side of the fixed shaft 61. The guide plate 62 is a rectangular plate with cylindrical grooves on the side. A constraint groove 63 is mirrored on both sides of the guide plate 62. The constraint groove 63 is a rectangular groove with a convex cross-section. A fixing frame 64 is vertically fixedly installed on the upper side of the outer casing 1 corresponding to the position of the guide plate 62. The fixing frame 64 is a U-shaped plate. A bolt group 65 is movably installed inside the constraint groove 63 and is movably arranged inside the fixing frame 64. The bolt group 65 consists of a cylindrical threaded rod and a nut.

[0029] Specifically, loosening the nut of bolt group 65 allows the threaded rod of bolt group 65 to slide inside the fixing frame 64. At the same time, the sliding of bolt group 65 inside the constraint groove 63 allows the guide plate 62 to rotate around the fixed shaft 61 as the rotation center to adjust the angle position. Tightening bolt group 65 fixes the guide plate 62 to the side of the fixing frame 64 for stability.

[0030] like Figure 2 and Figure 4 , Figure 5 As shown, the cleaning mechanism 7 includes a mounting block 71 fixedly installed on the side of the connecting plate 3, with the mounting block 71 positioned corresponding to the position of the crushing plate 5. The mounting block 71 is a trapezoidal plate, and a mounting cavity 72 is formed on the side of the mounting block 71 near the crushing plate 5. The mounting cavity 72 is a rectangular cavity, and a trigger plate 73 is movably installed inside the mounting cavity 72. The trigger plate 73 is an "L"-shaped plate with a beveled corner. A first spring 74 is symmetrically fixedly connected between the side of the trigger plate 73 and the inner wall of the mounting cavity 72. A connecting cavity 75 is formed on the inner wall of the mounting cavity 72 corresponding to the position of the trigger plate 73. The connecting cavity 75 is a rectangular cavity with a convex cross-section. A movable block 76 is movably installed at the position of the connecting cavity 75. The movable block 76 is a rectangular block. A deformable block 77 is fixedly installed on the side of the movable block 76 and is located inside the connecting cavity 75. The deformable block 77 is a ring block made of elastic material. A connecting block 78 is fixedly installed on the side of the movable block 76 and extends to the protrusion inside the connecting cavity 75. The connecting block 78 is a rectangular block. A second spring 781 is fixedly connected between the side of the connecting block 78 and the inner wall of the connecting cavity 75. The elastic force of the first spring 74 is greater than that of the second spring 781. A cleaning plate 79 is fixedly installed on the side of the movable block 76 and extends out of the position inside the mounting cavity 72.

[0031] Specifically, the first spring 74 presses the trigger plate 73, causing the movable block 76 to slide and push the cleaning plate 79 to adhere to the side of the crushing plate 5 for cleaning. At the same time, the connecting block 78 can compress and deform the second spring 781. The cleaning plate 79 slides to the serrated protrusion of the crushing plate 5 and is pressed. The cleaning plate 79 drives the movable block 76 to compress and deform the deformation block 77 and slide into the connecting cavity 75. The movable block 76 loses the pressure of the trigger plate 73 and slides into the innermost position of the connecting cavity 75 under the deformation force of the second spring 781. The cleaning plate 79 then retracts to avoid the serrated protrusion of the crushing plate 5. Simultaneously, the trigger plate 73 also slides out of the mounting cavity 72 under the push of the first spring 74. The trigger plate 73 is pressed by the serrated protrusion of the crushing plate 5 and slides into the mounting cavity 72. The movable block 76 slides out of the connecting cavity 75 under the deformation force of the deformation block 77 and is pressed by the trigger plate 73. This repeated triggering allows the cleaning plate 79 to adhere to the side of the crushing plate 5 for continuous cleaning.

[0032] In summary: The guide mechanism 6 can be adjusted according to the quantity of paper products, allowing the paper products to reach the crushing plate 5 at an effective angle for direct crushing. The cleaning mechanism 7 can clean the sides of the crushing plate 5 while it is being crushed. During cleaning, the cleaning mechanism can retract at the serrated protrusions of the crushing plate 5 to avoid interference, ensuring the cleaning effect of the crushing plate 5.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
