[0024] In the first embodiment, the shredding mechanism includes a shredding box 2 fixedly mounted on the top of the recycling box 1, and corresponding circulation grooves are provided on the top of the recycling box 1 and the bottom of the shredding box 2, and the grooves are consistent in size, which is conducive to the circulation of shredded paper. A feed pipe 3 is fixedly mounted on the top of the shredding box 2, and a brake motor 4 is fixedly mounted on the left side of the shredding box 2. The output shaft of the brake motor 4 is fixedly mounted with a first rotating rod 5 rotatably connected to the shredding box 2, and a driving gear 6 is fixedly mounted on the outer side of the first rotating rod 5.

[0025] Among them, the inside of the crushing box 2 is rotatably connected to the second rotating rod 7 extending to the outside, and two movable grooves are opened inside the crushing box 2. The first rotating rod 5 and the second rotating rod 7 are rotatably connected to the crushing box 2 through the corresponding movable grooves, which helps the first rotating rod 5 and the second rotating rod 7 to rotate inside the crushing box 2. A driven gear 8 that fits with the driving gear 6 is fixedly installed on the outside of the second rotating rod 7, and a crushing knife 9 is arranged on the outside of the first rotating rod 5 and the outside of the first rotating rod 5.

[0026] In the second embodiment, a screening mechanism is arranged inside the recycling box 1, and the screening mechanism includes a fixed shaft 10 fixedly installed on the inner walls on the left and right sides of the recycling box 1. The inner walls on the left and right sides of the recycling box 1 are provided with installation grooves, and the fixed shaft 10 is fixedly connected to the recycling box 1 through the installation grooves, which helps to install the fixed shaft 10. Two vibration springs 11 are mounted on the outer side of the fixed shaft 10, and a slider 12 slidably connected to the fixed shaft 10 is fixedly installed between the two vibration springs 11. A sliding groove is arranged inside the slider 12, and the slider 12 is slidably connected to the fixed shaft 10 through the sliding groove, which helps the slider 12 to slide on the outer side of the fixed shaft 10.

[0027] Among them, a screening box 13 is fixedly installed between the two sliders 12, and a filter plate 14 is fixedly installed inside the screening box 13. A plurality of filter holes are opened inside the filter plate 14, and the filter holes are evenly arranged, which is convenient for filtering shredded paper. A vibration motor 15 connected to the screening box 13 is fixedly installed on the inner bottom wall of the recycling box 1, and a discharge pipe 16 is fixedly installed on the right side of the screening box 13. A pipe groove is opened on the right side of the recycling box 1, and the discharge pipe 16 extends to the outside of the recycling box 1 through the pipe groove.

[0028] It should be noted that the corrugated cardboard recycling and crushing device, through the set crushing mechanism and screening mechanism, uses the brake motor 4, driving gear 6 and driven gear 8 to drive the first rotating rod 5 and the second rotating rod 7 to rotate in opposite directions, thereby driving the crushing knife 9 to rotate in opposite directions, and can crush and cut the corrugated paper. Using the vibration motor 15 and the vibration spring 11, the screening box 13 can be driven to vibrate rapidly, so that the fragments falling on the filter plate 14 can be quickly screened, and large-volume fragments are intercepted at the top of the filter plate 14, and smaller-volume fragments pass through the filter plate 14 into the bottom of the screening box 13, and finally are recovered through the discharge pipe 16, which is convenient for subsequent crushing and processing.

[0029] The working principle of the above embodiment is:

[0030] When the corrugated cardboard recycling and crushing device is used, the brake motor 4 is first started, and the brake motor 4 drives the first rotating rod 5 to rotate. The rotation of the first rotating rod 5 drives the driving gear 6 to rotate, and the driving gear 6 drives the driven gear 8 and the second rotating rod 7 to rotate in opposite directions, so that the crushing knives 9 on the first rotating rod 5 and the second rotating rod 7 rotate in opposite directions, and then the corrugated paper can be fed into the crushing box 2 through the feeding pipe 3. When the corrugated paper passes through the crushing knife 9, the crushing knife 9 cuts and crushes the corrugated paper. The crushed fragments slide inside the crushing box 2 and enter the inside of the recycling box 1, and fall into the inside of the sub-screening box 13. At the same time, the vibration motor 15 can be started, and the vibration motor 15 drives the sub-screening box 13 The screening box 13 vibrates rapidly, and the up and down vibration drives the slider 12 to move rapidly up and down on the outside of the fixed shaft 10, and retracts and contracts the vibration spring 11. The vibration spring 11 resets to support the slider 12 and the screening box 13, which can increase the vibration stability of the screening box 13, so that after the fragments fall onto the filter plate 14, they are quickly screened under the vibration of the screening box 13, and the larger fragments are intercepted on the top of the filter plate 14, and the smaller fragments pass through the filter plate 14 into the bottom of the screening box 13, and are finally recovered through the discharge pipe 16. The fragments intercepted on the filter plate 14 can be taken out separately, which is convenient for subsequent crushing and processing, and helps to improve the flexibility and practicality of the device.
