At the same time, the magnetic drive belt inside the first conveyor belt attracts the iron pieces in the plastic fragments. The rotation of the vibrating rod can shake off the plastic adhering to the top of the first conveyor belt. When the iron pieces are below the first conveyor belt, they are attracted by the magnetic drive belt and continue to be conveyed forward until they reach the front end of the second conveyor wheel. Due to the attraction of the magnetic drive belt, they fall into the iron collection tank, thus achieving the function of separating and collecting iron fragments. Attached Figure Description

[0018] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0020] like Figures 1-8 The illustrated biodegradable plastic product recycling and reprocessing equipment includes a device body 1. A first crushing mechanism 2 for crushing plastic products is located at the upper end of the device body 1. A cooling mechanism 3 for cooling circulating water is located at the end of the device body 1 furthest from the first crushing mechanism 2. A conveying and screening mechanism 4 for conveying the crushed plastic products is located below the first crushing mechanism 2 and the cooling mechanism 3 inside the device body 1. A second crushing mechanism 5 for further crushing the plastic products is located below the conveying and screening mechanism 4 inside the device body 1. A drying assembly 6 for conveying and drying the crushed plastic products is located below the second crushing mechanism 5 inside the device body 1.

[0021] The first crushing mechanism 2 includes a power motor 201 fixedly connected to the side surface of the device body 1. A first upper crushing wheel 204 and a second upper crushing wheel 205 are rotatably connected to the inner wall of the device body 1. A drive wheel 202 is fixedly connected to the output shaft of the power motor 201. A first crushing transmission belt 203 is driven to the outer surface of the drive wheel 202. A first upper gear 207 is fixedly connected to one end of the first upper crushing wheel 204. A feed inlet 206 is fixedly connected to one end of the second upper crushing wheel 205. The drive wheel 202 and the first upper crushing wheel 204 are driven to be connected by the first crushing transmission belt 203. The first upper gear 207 and the second upper gear 208 are meshed together.

[0022] Furthermore, the plastic scraps fed into the device body 1 through the feed inlet 206 will be crushed once by the first crushing mechanism 2, and the crushed plastic scraps will fall onto the first conveyor belt 405 for conveying.

[0023] The cooling mechanism 3 includes a rotating cooling shaft 302 rotatably connected inside the device body 1. A threaded pipe 301 is fixedly connected to the inner wall of the device body 1. A first cooling return water pipe 304 is fixedly connected to one end of the threaded pipe 301. Multiple rotating fans 303 are fixedly connected to the outer surface of the rotating cooling shaft 302. A first cooling tank 307 is opened inside the device body 1. A cooling water inlet pipe 305 and a second cooling water return pipe 306 are inserted into the device body 1. A cooling transmission belt 308 is drivenly connected to the outer surface of the rotating cooling shaft 302. The cooling mechanism 3 is located inside the first cooling tank 307. One end of the second cooling water return pipe 306 is connected to the threaded pipe 301, and the other end is inserted into the device body 1 and communicates with the first cooling tank 307. The first cooling water return pipe 304 and the second cooling water return pipe 306 are connected through the threaded pipe 301. The cooling water inlet pipe 305 is inserted into the device body 1 and communicates with the first cooling tank 307. The rotating fans 303 are located inside the threaded pipe 301.

[0024] Furthermore, the cool water inside the first cooling tank 307 is drawn out through the cooling water inlet pipe 305 and injected into the first lower crushing wheel 503 and the second lower crushing wheel 504. Then, the hot water discharged from the first lower crushing wheel 503 and the second lower crushing wheel 504 is cooled once inside the first cooling tank 307 through the threaded pipe 301, and then re-injected into the first cooling tank 307 through the second cooling water return pipe 306 to achieve the effect of circulating cooling.

[0025] The conveying and screening mechanism 4 includes a first conveying wheel 401 rotatably connected inside the device body 1, a second conveying wheel 402 and a vibrating rod 403 rotatably connected inside the device body 1, a magnetic drive belt 404 drivingly connected to the outer surfaces of the first conveying wheel 401 and the second conveying wheel 402, a first conveying belt 405 drivingly connected to the outer surface of the first conveying wheel 401, a conveying drive wheel 406 fixedly connected to the outer surface of the first conveying wheel 401, a second conveying drive belt 407 drivingly connected to the outer surface of the conveying drive wheel 406, an iron block collecting trough 408 slidably connected inside the device body 1, a first conveying drive belt 409 drivingly connected to the outer surface of the second upper crushing wheel 205, the first conveying wheel 401 and the second conveying wheel 402 being drivenly connected by the magnetic drive belt 404, the conveying drive wheel 406 and the vibrating rod 403 being drivenly connected by the second conveying drive belt 407, the first conveying belt 405 being drivenly connected inside the magnetic drive belt 404, and the first conveying wheel 401 being drivenly connected to the second upper crushing wheel 205 by the first conveying drive belt 409.

[0026] Furthermore, the plastic fragments crushed by the first crushing mechanism 2 fall above the first conveyor belt 405 for conveying. When they reach the rear end of the first conveyor belt 405, they fall into the interior of the second crushing mechanism 5. At the same time, the magnetic drive belt 404 inside the first conveyor belt 405 will attract the iron pieces in the plastic fragments. By rotating the vibrating rod 403, the plastic adhering to the top of the first conveyor belt 405 can be shaken off. When the iron pieces are below the first conveyor belt 405, they will be attracted by the magnetic drive belt 404 and continue to be conveyed forward until they reach the front end of the second conveyor wheel 402. Due to the attraction of the magnetic drive belt 404, they will fall into the iron collection groove 408, thus achieving the function of separating and collecting iron fragments.

[0027] The second crushing mechanism 5 includes an inclined plate discharge port 501 fixedly connected inside the device body 1, an inclined plate discharge port 502 fixedly connected inside the device body 1, a first lower crushing wheel 503 and a second lower crushing wheel 504 rotatably connected inside the device body 1, threaded cooling grooves 505 formed on the inner walls of the first lower crushing wheel 503 and the second lower crushing wheel 504, a first lower gear 506 fixedly connected to the outer surface of one end of the first lower crushing wheel 503, a second lower gear 507 fixedly connected to the outer surface of one end of the second lower crushing wheel 504, a first cooling return water pipe 304, and a cooling inlet water pipe 305. The bottom end of the 05 is inserted into the interior of the first lower crushing wheel 503 and the second lower crushing wheel 504, and the first cooling water return pipe 304 and the cooling water inlet pipe 305 are rotatably connected to the first lower crushing wheel 503 and the second lower crushing wheel 504. The outer surface of the second lower crushing wheel 504 is connected to the second crushing transmission belt 508. The drying assembly 6 includes a drying device 601 fixedly connected inside the device body 1. The lower end of the device body 1 is provided with a second conveyor belt 602. The drying device 601 is located above the second conveyor belt 602. The lower surface of the device body 1 is fixedly connected with a support leg 7.

[0028] Furthermore, when the plastic is crushed by the first lower crushing wheel 503 and the second lower crushing wheel 504, the threaded cooling grooves 505 set inside the first lower crushing wheel 503 and the second lower crushing wheel 504 play a role in circulating cooling. Cold water enters from one end of the first lower crushing wheel 503 and the second lower crushing wheel 504, and then carries away the heat inside the first lower crushing wheel 503 and the second lower crushing wheel 504, thereby achieving the effect of cooling the plastic during crushing.

[0029] Working principle: Plastic scraps fed into the device body 1 through the feed inlet 206 are crushed once by the first crushing mechanism 2. The crushed plastic scraps fall onto the first conveyor belt 405 for conveying. When they reach the rear end of the first conveyor belt 405, they fall into the second crushing mechanism 5. At the same time, the magnetic drive belt 404 inside the first conveyor belt 405 attracts iron pieces from the plastic scraps. The rotation of the vibrating rod 403 shakes off the plastic scraps adhering to the first conveyor belt 405. When the iron pieces are below the first conveyor belt 405, they are attracted by the magnetic drive belt 404 and continue to be conveyed forward until they reach the front end of the second conveyor wheel 402. Due to the attraction of the magnetic drive belt 404, they fall into the iron collection tank 408, achieving the function of separating and collecting iron scraps. After being crushed once by the first crushing mechanism 2, the plastic scraps are conveyed to the second crushing mechanism 5 through the first conveyor belt 405. When the first lower crushing wheel 503 and the second lower crushing wheel 504 crush the plastic scraps, they are further crushed. The crushing process is achieved through a series of circulating cooling mechanisms. Simultaneously, the threaded cooling grooves 505 inside the first and second lower crushing rollers 503 and 504 provide circulating cooling. Cold water enters from one end of each roller, carrying away heat. Cool water in the first cooling groove 307 is drawn through the cooling inlet pipe 305 and injected into the rollers. Hot water discharged from the rollers passes through the threaded pipe 301 and is first cooled in the first cooling groove 307, then re-injected into the first cooling groove 307 through the second cooling return pipe 306, achieving circulating cooling. Finally, the plastic fragments, after secondary crushing by the second crushing mechanism 5, fall onto the second conveyor belt 602 for transport. A drying device 601 above the second conveyor belt 602 dries the plastic fragments.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
