DETAILED DESCRIPTION

[0020] In order to more clearly illustrate the technical solution of the utility model, the utility model is further described below in conjunction with the accompanying drawings. Obviously, the accompanying drawings described below are only one embodiment of the utility model. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on this drawing and embodiment, which all belong to the protection scope of the utility model.

[0021] according to Figure 1-5 As shown, a feeding device of a plastic crusher includes a feed hopper 1, on the inner wall of which a movable plate 3 is movably installed, the feed hopper 1 is fixed on a fixed frame 2 by bolts, a rotating ring 4 is provided on the periphery of the feed hopper 1, the rotating ring 4 is rotatably installed on the fixed frame 2, and a first top block 5 for driving the movable plate 3 to move is fixedly installed on the top of the rotating ring 4.

[0022] In this embodiment, the feed hopper 1 is a rectangular structure, and slide grooves 6 are provided on the four inner walls of the feed hopper 1. A movable plate 7 is slidably installed in the slide groove 6. A movable plate 3 is fixedly installed on the end of the movable plate 7 close to the feed hopper 1, and a second top block 8 matching the first top block 5 is fixedly installed on the bottom of the movable plate 7 away from the end of the feed hopper 1. The second top block 8 is located above the rotating ring 4. When the rotating ring 4 rotates, the first top block 5 will contact the second top block 8, thereby lifting the movable plate 7 upward.

[0023] In this embodiment, the adjacent ends of the first top block 5 and the second top block 8 are both arc-shaped structures. When the first top block 5 approaches the second top block 8, the arc edges of the first top block 5 and the second top block 8 are first in contact, thereby avoiding a large collision between the first top block 5 and the second top block 8, and the second top block 8 can be lifted upward by the first top block 5.

[0024] In this embodiment, a hydraulic buffer rod 9 is fixedly installed at the bottom of the movable plate 3, and the other end of the hydraulic buffer rod 9 is fixedly installed on the top of the fixed frame 2. After the first top block 5 lifts the movable plate 3, the rotating ring 4 continues to rotate and the first top block 5 moves away from the bottom of the movable plate 3 along with the rotating ring 4. At this time, the movable plate 3 slides downward under the action of gravity, and the hydraulic buffer rod 9 plays a buffering role, so that the movable plate 3 can slide downward slowly, reduce the impact on the movable plate 3 when falling, and improve the service life of components.

[0025] In this embodiment, an inner gear ring 10 is fixedly installed on the inner wall of the bottom end of the rotating ring 4, and a gear 11 that matches the inner gear ring 10 is rotatably installed on the bottom of the fixed frame 2. A motor fixing frame 12 is provided below the gear 11. The motor fixing frame 12 is fixedly installed on the bottom of the fixed frame 2 by bolts. A servo motor 13 is fixedly installed on the motor fixing frame 12. The power output shaft of the servo motor 13 is fixedly connected to the rotating shaft of the gear 11. The gear 11 is driven to rotate by the servo motor 13, and the rotating ring 4 is driven to rotate on the fixed frame 2 under the action of the gear 11 and the inner gear ring 10.

[0026] In this embodiment, two groups of crushing rollers 14 are rotatably mounted at the bottom of the feed hopper 1 , and a discharge port 15 is provided below the crushing rollers 14 . The plastics fed into the feed hopper 1 are crushed by the crushing rollers 14 and then discharged outward through the discharge port 15 .

[0027] When the utility model is in use, the recycled waste plastics are put into the feed hopper 1, crushed by the crushing roller 14 in the feed hopper 1, and the servo motor 13 is started at the same time, and the servo motor 13 drives the rotating ring 4 to rotate on the fixed frame 2. When the rotating ring 4 rotates, the first top block 5 passes under the movable plates 7 on the four side walls of the feed hopper 1 in sequence, and the movable plates 3 are lifted up in sequence under the cooperation of the first top block 5 and the second top block 7, so that the plastic stuck on the side wall is changed from a horizontal state to a vertical state, thereby avoiding blockage inside the feed hopper, and effectively improving the crushing efficiency.

[0028] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
