For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0025] like Figure 1As shown, a shredding device for recycling waste paper includes a housing 1, a slitting device 2, a shredding knife 3, two cover plates 4, two partition plates 5 and two supporting plates 6. The housing 1 is set as a through structure from top to bottom, and a leg is set at the lower end. The two cover plates 4 are symmetrically arranged at the upper end of the housing 1 and are hinged to the housing 1. The two supporting plates 6 are symmetrically arranged at the lower end of the housing 1 and can move relatively under the action of external force. The two partition plates 5 are symmetrically and adjustable in the middle of the housing 1. By setting the partition plates 5, the housing 1 is divided into two upper and lower spaces. The slitting device 2 is arranged in the upper space, and two groups of shredding knives 3 are arranged in the lower space. When the device is used to slitting and shredding waste paper, the cover plate 4 is turned over, and the two partition plates 5 are in contact with each other to isolate the upper and lower spaces. The staff puts the waste paper into the upper space and starts the slitting device 2. The waste paper is cut into small-sized paper by the slitting device 2 to achieve preliminary paper processing. Therefore, the upper space can also be called the slitting space. After the paper is cut, the two partition plates 5 move away from each other, and the cut paper falls into the lower space, and the crushing knife 3 is started. Under the action of the crushing knife 3, the small-sized paper is fully crushed. Therefore, the lower space can be called the crushing space. After the cut paper falls into the crushing space, the two partition plates 5 move closer to each other and isolate the upper and lower spaces, so that waste paper can continue to be put into the cutting space, realizing continuous cutting and crushing of waste paper. This method changes the current situation that the crushing device is only equipped with one set of crushing units and cannot efficiently and effectively crush waste paper, and improves the crushing efficiency of waste paper.

[0026] like Figure 2 , Figure 3As shown, in order to realize the slitting of waste paper, the slitting device 2 includes a motor, a transmission belt 23, two main boards 21 and a plurality of slitting knives 22. The two main boards 21 are symmetrically arranged, and the lower ends are in sliding contact with the partition plate 5. The plurality of slitting knives 22 are evenly divided into two groups, and the two groups of slitting knives 22 are respectively arranged on the side walls of the two main boards 21 close to each other, and the two groups of slitting knives 22 are staggered. The housing 1 and the main board 21 are respectively provided with a perforation 14 and a connecting hole 25, the perforation 14 and the connecting hole 25 are directly opposite, the transmission belt 23 is arranged through the perforation 14 and the connecting hole 25, the two sides of the transmission belt 23 are respectively fixedly connected to the two main boards 21, the end of the transmission belt 23 protruding from the housing 1 is sleeved on the support shaft, the support shaft is fixedly connected to the housing 1, and the motor controls a certain support shaft to rotate. The housing 1 and the main board 21 are respectively provided with a through hole 15 and a sliding hole 27, the through hole 15 is fixedly provided with a limiting rod 24, and the limiting rod 24 is arranged through the sliding hole 27. When the slitting device 2 is working, the motor controls the transmission belt 23 to rotate. Since the two main boards 21 are fixedly connected to the two sides of the transmission belt 23, the two main boards 21 are close to each other, forcing the two sets of cutters 22 to slit the waste paper, cutting the waste paper into smaller sizes, and completing the processing of the waste paper. After the waste paper is slid, the motor rotates in the opposite direction to control the two main boards 21 to move away from each other until they are placed in contact with the shell 1. In the process of the two main boards 21 moving away from each other, the partition plate 5 can move relatively to make the upper and lower spaces communicate with each other so that the cut paper can fall. A limiting rod 24 is provided to support and limit the two main boards 21, so that the main boards 21 are stably and movably arranged in the shell 1.

[0027] like Figure 4 As shown, in order to prevent the existence of the main board 21 from affecting the slitting of paper by the slitting knife 22, a plurality of filling holes 26 are provided on the main board 21. The number of the filling holes 26 is equal to the number of the slitting knives 22 in each group, and the filling holes 26 are adjacent to the slitting knives 22. When two main boards 21 are close to each other and the distance between them is small, the slitting knife 22 can be inserted into the filling holes 26, which provides convenience for fully slitting waste paper and avoids damage to the slitting knife 22.

[0028] like Figure 1 , Figure 7 As shown, the paper falling into the shredding space can be fully shredded by the two groups of shredding knives 3. To achieve this purpose, the ends of the two groups of shredding knives 3 are both arranged to penetrate the side wall of the shell 1, and a first gear 31 is arranged at one end of the shredding knives 3. A second gear 32 is connected between the two first gears 31. One group of shredding knives 3 is connected to the motor, and the two groups of shredding knives 3 work synchronously to effectively shred the paper falling into the shredding space.

[0029] like Figure 2 , Figure 5As shown, in order to control whether the upper and lower spaces are connected or not, a first strip hole 11 and a second strip hole 12 are provided on the housing 1, and the partition plate 5 is provided through the second strip hole 12. At the same time, a connecting plate 53 is provided through the first strip hole 11, and a plug rod is fixedly provided on the connecting plate 53, and a connecting bolt is provided through the connecting plate 53. The plug rod can be inserted into the slot 54 of the partition plate 5, and the end of the connecting bolt can be threadedly inserted into the thread groove 55 of the partition plate 5. The two connecting plates 53 match the two partition plates 5 one by one. A bidirectional screw 51 is provided on the outer side of the housing 1 opposite to the first strip hole 11, and the end of the bidirectional screw 51 is connected to the output shaft of the motor. Two internal threaded tubes 52 are threadedly sleeved at both ends of the bidirectional screw 51, and the two internal threaded tubes 52 are respectively connected to the two connecting plates 53 one by one. Therefore, when the motor controls the bidirectional screw 51 to rotate, the two partition plates 5 can be controlled to move relative to each other, providing support for the isolation or connection of the upper and lower spaces.

[0030] like Figure 1 , Figure 2 As shown, the lower end of the shell 1 is provided with a third strip hole 13, and the support plate 6 is provided through the third strip hole 13. The ends of the two support plates 6 that are away from each other can be provided with handles, so that the staff can pull the support plates 6 to move relative to each other according to needs. Of course, the relative movement of the two support plates 6 can also be set in accordance with the two partition plates 5. After the paper is fully shredded, the two support plates 6 are away from each other, so that the lower end of the shell 1 is unobstructed, so as to discharge the shredded paper. A collection bin can also be provided at the lower end of the shell 1 to collect the shredded paper. In order to facilitate the control of the operation of the device, a control box can also be provided on the shell 1. The control box is a prior art and will not be described in detail here.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be modified and varied in various ways. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
