Therefore, it is entirely possible to recycle them and reprocess them into plastic products by appropriate methods for reuse. In order to facilitate the recycling of waste plastics, it is necessary to compress them. The existing compression devices for waste plastics have problems such as inability to crush materials and low compression efficiency when in use. For this reason, we propose a compression device for waste plastics. Content of the Utility Model

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-4, the present utility model provides a technical solution: a compression device for waste plastics, including a box body 1. The bottom of the inner wall of the box body 1 near the left and right sides is inclined downward. The inner walls of the box body 1 near the left and right sides are respectively movably connected with rotating rollers 8 through rotating shafts and bearings. The front end of the rotating shaft on the left side in the front extends through the inner ring of the bearing to the front of the box body 1 and is fixedly connected with a driving motor 12. The rear wall of the driving motor 12 is fixedly connected with the front wall of the box body 1 through a connecting rod. A plurality of annular blocks 10 arranged in the front-rear direction are sleeved on the rotating rollers 8, and the outer walls of the annular blocks 10 are serrated. The rear ends of the two rotating shafts at the rear pass through the inner ring of the bearing to the rear of the box body 1 and are fixedly connected with gears 11. The two gears 11 are meshed with each other. A compression box 3 is arranged below the box body 1. A through groove is opened at the top of the compression box 3, and a feeding cover 9 is fixedly connected to the inner wall of the through groove. The bottom of the box body 1 near the left and right sides is fixedly connected with the top of the compression box 3 through two connecting rods arranged in the front-rear direction. The bottom of the box body 1 penetrates through the top of the compression box 3 near the middle. A compression plate 4 is arranged near the middle in the compression box 3. A movable baffle 6 is fixedly connected to the upper part of the left wall of the compression plate 4. A hydraulic cylinder 7 is fixedly connected to the left wall of the compression box 3. An output shaft 5 is arranged on the right wall of the hydraulic cylinder 7, and a through hole matching the output shaft 5 is opened on the left wall of the compression box 3. The right end of the output shaft 5 passes through the through hole and is fixedly connected to the left wall of the compression plate 4. A manual valve plate 2 is arranged near the right side in the compression box 3. Support rods are fixedly connected to the four corners of the bottom of the box body 1. Through the mutual cooperation among the driving motor 12, the gears 11, and the rotating rollers 8, the two rotating rollers 8 can drive a plurality of annular blocks 10 evenly distributed on the left and right sides to rotate towards each other, so that through the serrated setting of the outer walls of the annular blocks 10, it is convenient to tear the plastics, thus facilitating compression and ensuring the compression effect; through the mutual cooperation among the hydraulic cylinder 7, the output shaft 5, and the compression plate 4, the compression plate 4 can move in the left-right direction, so as to conveniently roll the shredded waste materials into blocks, effectively improving the compression efficiency of the device.

[0020] Working principle: When in use, the materials enter the box body 1 through the feeding cover 9. The driving motor 12 is started to drive the rotating roller 8 on the left side to rotate forward, and at the same time, the two gears 11 drive the rotating roller 8 on the right side to rotate reversely. At this time, a plurality of annular blocks 10 on the left and right sides rotate in opposite directions, and the waste materials are torn by their outer walls, which is convenient for subsequent compression and ensures the compression effect. The shredded materials fall into the middle and lower parts in the compression box 3. The hydraulic cylinder 7 is started to drive the output shaft 5 to move downward, and then drive the compression plate 4 to move downward to compress the materials. At the same time, the movable baffle 6 moves downward to block the discharge port at the bottom of the box body 1 to prevent continuous feeding during the compression process. After compression, the hydraulic cylinder 7 contracts, the manual valve plate 2 is manually opened, and the materials are taken off.
