[0002] A shredder is a device used to cut various items into smaller pieces. It is widely used in the fields of waste treatment, reuse and recycling. It is mainly based on the mechanical principles of shearing, tearing and crushing. The material first enters the device through the inlet of the shredder. Then, inside the shredder, one or more sets of rotating cutting blades or gears apply shear and tearing forces to the material, breaking the material into smaller pieces. These pieces may be further compressed and crushed to achieve the desired particle size and density, and finally discharged through the shredder outlet.
[0003] In the traditional production process of stone plastic box board, the scraps of stone plastic box board are cut online. These scraps usually need to be collected manually and then crushed and screened separately. This process is not only time-consuming and labor-intensive, but also increases production costs.
[0004] Traditional shredders cannot adjust the distance between the two blade axes to adapt to scraps of different sizes and thicknesses when shredding stone plastic box boards, and thus cannot meet the production needs of diverse recycling; secondly, adjusting the distance between the two blade axes will also cause the stone plastic box boards to be unable to smoothly enter the blades for shredding, causing them to always hover above the blades, and there is a problem of insufficient shredding of materials between the two sides of the blades, which results in the traditional shredder requiring a screen to continuously increase the shredding time to achieve the shredding purpose.

[0052] Among them, Figure 7-Figure 9 As shown, the adjustment component 11 is used to seal the side wall of the shredder box 2 when the first installation shaft 13 and the second installation shaft 14 move laterally. The adjustment component 11 includes a second installation plate 112 fixedly connected to the middle position of the installation groove 10, and the first installation plate 111 and the third installation plate 119 are symmetrically fixedly connected on both sides of the installation groove 10, and the first installation plate 111 and the third installation plate 119 are both provided with a first sliding cavity 125, the first sliding cavity 125 in the first installation plate 111 is slidably connected to the first movable plate 113, and the first sliding cavity 125 in the third installation plate 119 is slidably connected to the fourth movable plate 117, and a blocking plate 120 is provided in the middle position of the second installation plate 112. A second sliding cavity 126 is symmetrically provided in the plate 112 on both sides of the blocking plate 120, wherein a second movable plate 114 corresponding to the first movable plate 113 is slidably connected in the second sliding cavity 126 on one side, and a third movable plate 116 corresponding to the fourth movable plate 117 is slidably connected in the second sliding cavity 126 on the other side, and a circular groove is commonly provided in the middle position of the first movable plate 113 and the second movable plate 114 and the third movable plate 116 and the fourth movable plate 117, and a first sealed bearing 115 and a second sealed bearing 118 are respectively provided in the groove, the first sealed bearing 115 is provided on the first mounting shaft 13, and the third movable plate 116 is provided on the second mounting shaft 14.
[0053] For further information, see Fig. 9As shown, a plurality of first springs 121 are arranged in the first sliding cavity 125, one end of the first spring 121 in the first mounting plate 111 is fixedly connected to the first movable plate 113, and the other end is fixedly connected to the inner wall of the first sliding cavity 125 in the first mounting plate 111, one end of the first spring 121 in the third mounting plate 119 is fixedly connected to the fourth movable plate 117, and the other end is fixedly connected to the inner wall of the first sliding cavity 125 in the third mounting plate 119; then a plurality of second springs 122 are arranged in the second sliding cavity 126 located on both sides of the blocking plate 120, wherein one end of the second spring 122 in the second sliding cavity 126 on one side is fixedly connected to the second movable plate 114, and the other end is fixedly connected to the blocking plate 120, and one end of the second spring 122 in the second sliding cavity 126 on the other side is fixedly connected to the third movable plate 116, and the other end is fixedly connected to the blocking plate 120;
[0054] The first and second sliding plates 113 and 114 are symmetrically provided with sliding grooves 124 adapted to the sliding rails 123 at the upper and lower tops and lower tops of the first and second sliding plates 114, the third and fourth sliding plates 116, and the fourth sliding plates 117. The sliding rails 123 and the sliding grooves 124 are both T-shaped structures. In this way, the first and second sliding plates 113, 114, the third and fourth sliding plates 116, and the fourth sliding plates 117 all slide on the sliding rails 123 through the sliding grooves 124 thereon, and always keep in contact with the upper and lower ends of the mounting grooves 10 to ensure the sealing of the tearing box 2. It should be noted that the first and second sliding plates 113, 114, the third and fourth sliding plates 116, and the fourth sliding plates 117 will never separate from the first and second sliding cavities 125 and 126 to ensure the sealing of the tearing box 2.
[0055] It is also worth mentioning that the first springs 121 and the second springs 122 are used to ensure that the first movable plate 113 and the second movable plate 114 are always in contact with each other, and the third movable plate 116 and the fourth movable plate 117 are always in contact with each other, and the card slot is adapted to the first sealed bearing 115 and the second sealed bearing 118. It should be supplemented here that the first movable plate 113 and the second movable plate 114 are provided to clamp the first sealed bearing 115, and the third movable plate 116 and the fourth movable plate 117 are provided to clamp the second sealed bearing 118, because such a setting facilitates the disassembly and installation of the first sealed bearing 1 15 and the second sealed bearing 118, thereby facilitating the installation of the first installation shaft 13 and the second installation shaft 14, and at the same time ensuring the airtightness of the entire shredder box 2 when the distance between the first installation shaft 13 and the second installation shaft 14 is adjusted; in this way, when the distance between the first installation shaft 13 and the second installation shaft 14 is moved, the first movable plate 113 and the second movable plate 114 will automatically clamp the first sealed bearing 115 under the action of the spring force, and the third movable plate 116 and the fourth movable plate 117 will automatically clamp the second sealed bearing 118 under the action of the spring force, and at the same time will not affect the rotation of the first installation shaft 13 and the second installation shaft 14.
[0056] For further information, see Fig.10 As shown, a plurality of first blade portions 8 are fixedly provided on the first mounting shaft 13, a plurality of second blade portions 9 corresponding to the first blade portions 8 and staggered therewith are fixedly provided on the second mounting shaft 14, a plurality of first cutting grooves 16 are provided on the first blade portion 8 to increase the degree of shredding of scraps, a plurality of first cutting grooves 16 are provided on the second blade portion 9, and a receiving groove 17 is also provided on the second blade portion 9 around the center position, a plurality of gathering components 15 matched with the receiving groove 17 are rotatably connected in the receiving groove 17 to gather the scraps between the first blade portion 8 and the second blade portion 9.
[0057] For details, see Figure 11-Figure 14The first cutting groove 16 and the second cutting groove 18 are both V-shaped structures, and are evenly arranged on a number of teeth of the first blade 8 and the second blade 9, respectively. The first cutting groove 16 and the second cutting groove 18 are through-opened on both sides, and the edges are sharp structures. In this way, the efficiency of shredding can be increased as much as possible without adding a large number of the first blade 8 and the second blade 9. When the scraps enter between the first blade 8 and the second blade 9, the upper end of the V-shaped structure and the sharp parts on the left and right sides can increase the chance of contacting and shredding the scraps. , thereby improving the shredding efficiency; it should also be added that the accommodating groove 17 is a circular ring structure concentric with the second knife portion 9, and the depth and width of the accommodating groove 17 are adapted to the plurality of gathering components 15 that can be accommodated in the accommodating groove 17. This arrangement is to ensure that when the plurality of gathering components 15 are working, if they are stuck or simultaneously hit the edge of the shredding box 2 or the first mounting shaft 13, the accommodating groove 17 can accommodate multiple gathering components 15 to be stuck, and then the next cycle continues to cut and pull, so as to increase the gathering and cutting of large scraps.
[0058] Among them, see Fig.14 and Fig.15 The gathering component 15 includes a cutting plate 151 rotatably connected to the accommodating groove 17, a hook 152 is fixedly connected to the top of the cutting plate 151, and a plurality of third cutting grooves 153 are evenly opened on the cutting plate 151. A torsion spring 154 is symmetrically arranged at the rotation connection between the cutting plate 151 and the accommodating groove 17. The torsion spring 154 always has a tendency to make the side of the cutting plate 151 be level with the tip of the tooth of the second knife part 9. In this way, the cutting plate 151 and the hook 152 can always keep rotating synchronously with the teeth of the second knife part 9. First, it can assist the second knife part 9 to tear up the scraps entering between the first knife part 8 and the second knife part 9. Second, when the scraps are large, the hook 152 can hook the scraps and drag them into the first knife part 8 and the second knife part 9 for the tearing process; and when the scraps are difficult to handle and difficult to drag in, the sharp structure under the cutting plate 151 and the hook 152 can also cut and pull them.
[0059] Further, such as Fig.15As shown, the cutting plate 151 is a tapered sharp structure, and the direction of the sharp structure is the same as the rotation direction of the second knife part 9, the hook 152 is a hook-shaped structure, and the hook is a sharp structure, and the third cutting groove 153 is an inverted V-shaped structure, and the two sides of the third cutting groove 153 are through-opened, and the edge is a sharp structure; it is worth mentioning that the length of the cutting plate 151 and the hook 152 is adapted to the opening size of the bottom end of the shredder box 2, and the opening edge of the bottom end of the shredder box 2 and the periphery of the hook 152 are smooth structures; It is worth mentioning here that the third cutting groove 153 is an inverted V-shaped structure, which, combined with the length of the cutting plate 151 and the position of the hook 152, is more conducive to shredding and cutting the scraps when it rotates and is inserted into the receiving groove 17; secondly, when the hook 152 rotates to the open position at the bottom end of the shredder box 2 and collides with the first mounting shaft 13, the smooth structure can make it rotate in the opposite direction and be inserted into the receiving groove 17. When the second knife part 9 is rotated to other positions, the cutting plate 151 is automatically reset by the torsion of the torsion spring 154.
[0060] In addition, if Figure 1 As shown, the bottom end of the shredder box 2 is open, and the bottom end is connected to an integrated vacuum pump mechanism 3, through which the shredded granular material is directly transported to a designated location, thereby achieving rapid recovery and secondary use of the material and reducing the material handling and reprocessing links.
[0061] In addition, Figure 1 As shown, the first drive component 4 includes a first guide rail 43 arranged on the mounting frame 1, a first mounting seat 42 adapted thereto is arranged on the first guide rail 43, and a first drive motor 41 is arranged on the first mounting seat 42; the second drive component 6 includes a second guide rail 63 arranged on the mounting frame 1, a second mounting seat 62 adapted thereto is arranged on the second guide rail 63, and a second drive motor 61 is arranged on the second mounting seat 62; the bottom ends of the first guide rail 43 and the second guide rail 63 are both provided with mechanisms for driving the first mounting seat 42 and the second mounting seat 62 to slide; in this way, when it is necessary to adjust the distance between the first mounting shaft 13 and the second mounting shaft 14, the movement of the entire first mounting shaft 13 and the second mounting shaft 14 can be realized through the driving mechanism at the bottom ends of the first guide rail 43 and the second guide rail 63, and the adjustment component 11 is cooperated to clamp and seal them to ensure that no gaps are generated during the entire adjustment process to prevent scraps from flying out.
