The auxiliary components 7 comprise connecting bars 17 and shielding blocks 18. Through the foregoing solution, the problem that the existing crushing device for recycling only plastic defective products works with only one crushing roller 5, has a poor crushing effect, and needs to be crushed multiple times to reach the particle size required for subsequent operations, and has a poor crushing effect is solved.
[0021] For this specific embodiment, the feed hopper 2 is fixedly connected above the crushing box 1. The debugging component 3 is arranged inside the crushing box 1. The driving part 8 is arranged inside the crushing box 1. The two motor boxes 9 are arranged on the driving part 8. The two crushing motors 4 are respectively fixedly connected inside the two motor boxes 9. The two crushing rollers 5 are respectively fixedly connected to the output ends of the two crushing motors 4. The plurality of crushing teeth 6 are respectively fixedly connected to the surfaces of the two crushing rollers 5 and are evenly distributed. The two auxiliary components 7 are arranged inside the crushing box 1. When crushing defective products, according to requirements, the two debugging components 3 are started. The distances between the two crushing motors 4 and the two crushing rollers 5 are adjusted through the two driving parts 8 and the two motor boxes 9. After it is appropriate, the two crushing motors 4 are started in opposite directions. The two crushing rollers 5 rotate in opposite directions, driving the plurality of crushing teeth 6 to rotate. The defective products are poured from the feed hopper 2 into the crushing box 1. The two auxiliary components 7 will guide the defective parts to fall between the two crushing rollers 5, rather than on both sides. The defective parts are crushed into plastic particles under the action of the rotating plurality of crushing teeth 6. After the crushing is completed, the combination of the two crushing rollers 5 and the plurality of crushing teeth 6 will make the crushing more thorough.
[0022] Among them, the driving double-threaded shaft 10 is rotatably connected to the inside of the crushing box 1, the auxiliary double-threaded shaft 11 is rotatably connected to the inside of the crushing box 1, the four moving members 12 are respectively arranged at both ends of the two crushing rollers 5, and the two motor boxes 9 are respectively arranged on one side of the two moving members 12 on the driving double-threaded shaft 10. When using the debugging component 3, the driving double-threaded shaft 10 and the auxiliary double-threaded shaft 11 rotate synchronously, and synchronously move the respective two moving members 12 closer to or away from each other, so as to adjust the distance between the two crushing rollers 5, so as to meet the requirements of different crushing particle diameters.
[0023] Secondly, the driving motor 13 is fixedly connected to the inside of the crushing box 1, and the output end is fixedly connected to the driving double-threaded shaft 10. The two transmission belts 14 are respectively sleeved at both ends of the driving double-threaded shaft 10 and the auxiliary double-threaded shaft 11. When using the debugging component 3, the driving motor 13 provides power, and the two transmission belts 14 transmit power to make the auxiliary double-threaded shaft 11 rotate synchronously with the driving double-threaded shaft 10.
[0024] At the same time, the moving block 15 is threadedly connected to the driving double-threaded shaft 10 or the auxiliary double-threaded shaft 11 and is slidably connected to the inside of the crushing box 1. The L-shaped arm 16 is rotatably connected to the crushing box 1, rotatably connected to the crushing roller 5, and fixedly connected to the lower part of the moving block 15. The motor box 9 is fixedly connected to the L-shaped arm 16. When using the debugging component 3, the driving motor 13 is started, the driving double-threaded shaft 10 rotates, and under the action of the two transmission belts 14, the auxiliary double-threaded shaft 11 rotates synchronously, so that the respective two moving blocks 15 move closer to or away from each other, thereby driving the two crushing rollers 5 to move closer to or away from each other through the plurality of L-shaped arms 16, so as to adjust the distance between the two crushing rollers 5, control the diameter of the particles after crushing, and meet different crushing requirements. At this time, the two crushing motors 4 in the two motor boxes 9 can be started in the opposite direction to make the two crushing rollers 5 roll in opposite directions, driving the plurality of crushing teeth 6 to rotate, and performing crushing work on the defective products entering the crushing box 1.
[0025] Finally, the connecting strip 17 is fixedly connected to the inside of the crushing box 1, and the shielding block 18 is fixedly connected to one side of the connecting strip 17. When the defective products enter the crushing box 1, they will be guided by the two connecting strips 17 and the two shielding blocks 18, and thus fall down between the two crushing rollers 5, and will not fall along the inner wall of the crushing box 1, preventing the crushing particle size from not meeting the requirements.
[0026] When crushing defective products, according to requirements, start the two debugging components 3. Adjust the distances between the two crushing motors 4 and the two crushing rollers 5 through the two driving parts 8 and the two motor boxes 9. After it is appropriate, start the two crushing motors 4 in opposite directions. The two crushing rollers 5 rotate in opposite directions, driving the multiple crushing teeth 6 to rotate. Pour the defective products from the feeding hopper 2 into the crushing box 1, and be guided by the two connecting bars 17 and the two blocking blocks 18, so as to fall towards the middle of the two crushing rollers 5 and will not fall along the inner wall of the crushing box 1, preventing the size of the crushed particles from not meeting the requirements. The defective parts are crushed into plastic particles under the action of the multiple rotating crushing teeth 6, and the crushing is completed. When using the debugging component 3, start the driving motor 13, and the driving double-threaded shaft 10 rotates. Under the action of the two transmission belts 14, the auxiliary double-threaded shaft 11 rotates synchronously, so that the two moving blocks 15 of each move closer to or away from each other, thereby driving the two crushing rollers 5 to move closer to or away from each other through the multiple L-shaped arms 16, so as to adjust the distance between the two crushing rollers 5 and control the diameter of the particles after crushing to meet different crushing requirements. At this time, the two crushing motors 4 in the two motor boxes 9 can be started in opposite directions to make the two crushing rollers 5 roll in opposite directions, driving the multiple crushing teeth 6 to rotate, and crushing the defective products entering the crushing box 1. The combination of the two crushing rollers 5 and the multiple crushing teeth 6 will make the crushing more thorough, avoiding the problem that the existing crushing device for recycling only plastic defective products relies on a single crushing roller 5 to work, resulting in poor crushing effect and requiring multiple crushing to reach the particle size required for subsequent operations, and obtaining the effect of improving the crushing efficiency.
