[0019] The following will be described in detail with reference to the accompanying drawings. Figs. 1-3 The application is further described in detail.

[0020] The embodiments of the application disclose a waste plastic recycling device. Figs. 1-3 A waste plastic recycling device, comprising a crusher 1, a feed hopper 2 is fixedly installed on the upper surface of the crusher 1, fixed grooves 3 are through-opened on the inner wall of the feed hopper 2 near the bottom of the four corners, a limiting pressing plate 4 is rotatably installed on the inner wall bottom of the feed hopper 2 near the fixed grooves 3, a connecting plate 5 is fixedly connected to the outside of the fixed groove 3 on the side of the limiting pressing plate 4 near the hinged shaft, the outer surface of the connecting plate 5 is located inside the fixed groove 3 on one side, the fixed groove 3 and the connecting plate 5 are mutually adapted, electric telescopic rods 6 are arranged on the both side edges of the upper surface of the crusher 1, a connecting frame 7 is installed on the outer surface of the feed hopper 2 on the output end of the upper surface of the electric telescopic rod 6, the connecting frame 7 is movably sleeved on the outer surface bottom of the feed hopper 2, the feed hopper 2 and the connecting frame 7 are mutually embedded, movable connecting plates 8 are symmetrically rotatably installed on the upper surface of the connecting frame 7 near the four corners, the movable connecting plates 8 are hingedly connected to the top of one side of the connecting plate 5, and a crushing device is further arranged in the crusher 1 for crushing the waste plastic.

[0021] By putting the waste plastic into the feed hopper 2, the electric telescopic rod 6 is operated to be shortened, the connecting frame 7 is moved downward, the connecting plate 5 is pushed through the movable connecting plate 8, and then the limiting pressing plate 4 is rotated to be closed, after the limiting pressing plate 4 is closed, the waste plastic with large volume can be preliminarily shaped and limited, so that the shape and volume are more easily entered into the crusher 1, and the smoothness of feeding is improved.

[0022] Referring to Fig. 2 and Fig. 3 The crushing device comprises crushing rollers 9, the crushing rollers 9 are symmetrically rotatably installed on the inner top of the crusher 1, a driving motor 10 is installed on one end of a single crushing roller 9 extending to the outside of the crusher 1, a No. 1 gear 12 is installed on the other end of the crushing roller 9 extending to the outside of the crusher 1, a fixed frame 11 is fixedly installed on the outer surface of the crusher 1 and placed outside the No. 1 gear 12, No. 2 gears 13 are symmetrically rotatably installed in the fixed frame 11 near the lower part of the No. 1 gear 12, the No. 2 gears 13 are movably close to the outer surface of the No. 1 gear 12, the No. 1 gear 12 and the No. 2 gears 13 are mutually meshed, the two No. 2 gears 13 are the same in shape and structure, and the two No. 2 gears 13 are mutually meshed.

[0023] By starting the driving motor 10, the output shaft of the driving motor 10 drives the crushing roller 9 connected thereto to rotate, and the No. 1 gear 12 at one end of the crushing roller 9 rotates synchronously with the crushing roller 9. Since the No. 1 gear 12 and the No. 2 gear 13 in the fixed frame 11 are meshed with each other, and the two No. 2 gears 13 are also meshed with each other, when the No. 1 gear 12 rotates, the other crushing roller 9 will rotate synchronously in the opposite direction through the transmission of the No. 2 gear 13. The synchronous reverse rotation of the two crushing rollers 9 can crush the waste plastics entering the inside of the crusher 1 by rolling.

[0024] The implementation principle of the waste plastic recycling device in the embodiment of the application is as follows: when it is necessary to regenerate and recycle waste plastics, first, the electric telescopic rod 6 is operated to extend, and the output end of the electric telescopic rod 6 drives the connecting frame 7 to move upward along the outer surface of the feeding hopper 2.

Since the connecting plate 5 is fixedly connected with the limiting pressing plate 4, and the limiting pressing plate 4 is rotatably installed on the inner wall bottom of the feeding hopper 2, the connecting plate 5 will drive the limiting pressing plate 4 to rotate around the hinge shaft, so that the limiting pressing plate 4 is opened.

Since the No. 1 gear 12 and the No. 2 gear 13 in the fixed frame 11 are meshed with each other, and the two No. 2 gears 13 are also meshed with each other, when the No. 1 gear 12 rotates, the other crushing roller 9 will rotate synchronously in the opposite direction through the transmission of the No. 2 gear 13, and the synchronous reverse rotation of the two crushing rollers 9 can crush the waste plastics entering the inside of the crusher 1 by rolling, so that the waste plastics are crushed into smaller particles, thereby completing the regeneration and recycling process of the waste plastics. The input ends of the electric telescopic rod 6 and the driving motor 10 power source are electrically connected with the output end of the external power source.
