When the former is in use, some of the shredded paper printed materials are scattered when falling, causing scattering in the working environment. When the latter is in use, it is necessary to stop the machine to replace the hopper. Otherwise, when the hopper is replaced, the shredded printed materials fall to the ground and need to be manually cleaned. Utility Model Content

[0004] The problem solved by the utility model is to provide a printed matter shredding device, which solves the technical problem that the existing shredding equipment, after completing the shredding, conveys and collects the printed matter through a transmission belt or a hopper. When the former is in use, some of the shredded paper printed matter scatters around when falling, causing scattering in the working environment. When the latter is in use, it is necessary to stop the machine to replace the hopper. Otherwise, when the hopper is replaced, the shredded printed matter falls to the ground and needs to be manually cleaned.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A printed material shredding device comprises a shell, a support plate, a material guide plate, a first crushing tooth and a second crushing tooth. Support plates are installed on both sides of the bottom of the shell. A material guide plate arranged in an inverted "eight" shape is installed inside the shell. The first crushing tooth and the second crushing tooth are rotatably installed inside the shell and below the material guide plate, and the first crushing tooth and the second crushing tooth are staggered. A translation plate is slidably installed on the bottom of the shell, and a hopper and a right-angle material baffle are installed on the translation plate.

[0007] Preferably, a gear box is installed on the side wall of the shell, and the ends of the first crushing teeth and the second crushing teeth are located in the gear box and transmission teeth are installed, and the two transmission teeth are meshed with each other.

[0008] Preferably, a reducer is installed on the outside of the gear box, the output end of the reducer is connected to one of the transmission teeth, and the input end of the reducer is connected to the output end of the first motor.

Support plates 2 are installed on both sides of the bottom of the shell 1. The guide plate 3 arranged in an inverted "eight" shape is installed in the shell 1. The first crushing tooth 4 and the second crushing tooth 5 are rotatably installed inside the shell 1 and below the guide plate 3. The first crushing tooth 4 and the second crushing tooth 5 are staggered. A translation plate 10 is slidably installed at the bottom of the shell 1, and a hopper 12 and a right-angle material baffle plate 13 are installed on the translation plate 10.

[0022] As an embodiment of the present utility model, a gear box 6 is installed on the side wall of the shell 1, and the ends of the first crushing tooth 4 and the second crushing tooth 5 are located in the gear box 6 and are equipped with transmission teeth 7, and the two transmission teeth 7 are meshed with each other. A reducer 8 is installed on the outside of the gear box 6, and the output end of the reducer 8 is connected to one of the transmission teeth 7, and the input end of the reducer 8 is connected to the output end of the first motor 9. When the first motor 9 works, the reducer 8 adjusts the speed to drive one of the transmission teeth 7 to rotate, and drives the two transmission teeth 7 to rotate synchronously through gear meshing transmission, thereby realizing the rotation of the first crushing tooth 4 and the second crushing tooth 5, and then the printed matter is crushed.

[0023] The second motor 14 is provided with a gear 15 and a gear 16 that meshes with the gear 16. The second motor 14 drives the gear 15 to rotate and cooperates with the meshing gear 16 to drive the translation plate 10 to move through the roller 11. The position of the hopper 12 and the right-angled baffle 13 are adjusted by the movement of the translation plate 10. When the hopper 12 is about to be full, the translation plate 10 drives the hopper 12 to move out from the bottom of the shell 1, and the right-angled baffle 13 moves to the bottom of the shell 1 to block the bottom of the shell 1, temporarily storing the crushed printed matter inside the shell 1, and then replacing the hopper 12 on the translation plate 10, and the translation plate 10 moves to the bottom of the shell 1 again to collect printed matter, and the replacement of the hopper 12 can be achieved without stopping the machine, which greatly improves the crushing efficiency.

[0024] As an embodiment of the present invention, a guide groove is provided on the inner side of the support plate 2, and guide blocks are installed on two opposite sides of the translation plate 10, and the guide blocks move along the guide groove.
