Detailed ways

As shown in Figures 1 and 2, a waste plastic crushing device includes a crushing cylinder 1 with a bracket 2 at the bottom, a crushing screen drum 3 inside the crushing drum 1, an upper end of the crushing screen drum 3, and a side wall and a bottom. Mesh holes for the crushed plastic fragments to leak down. The top of the crushing cylinder 1 is equipped with a crushing motor 4. The output end of the crushing motor 4 is connected to the crushing shaft 5. The crushing shaft 5 extends into the crushing screen drum 3. On the crushing shaft 5 There are a number of blades 6, the two sides of the crushing screen cylinder 3 are connected with the inner wall of the crushing cylinder 1 through springs 7, the inner wall of the crushing cylinder 1 is provided with a support frame 9 for supporting the motor 8, and the rotating shaft of the motor 8 is equipped with a cam 10, and the cam 10 rotates The extrusion force is formed on the crushing screen drum 3 to make the crushing screen drum 3 vibrate left and right. The upper end of the crushing drum 1 is provided with a feeding port 101, and the lower end is provided with a discharge port 102. The discharge port 102 is provided with a valve 11.

The set motor 8 and the cam 10 form a reciprocating extrusion force on the crushing screen cylinder 3, and under the joint action of the spring 7, the crushing screen cylinder 3 reciprocates left and right, which is beneficial to The plastic pieces fall from the crushing screen cylinder 3 into the crushing cylinder 1, which realizes the separation of the broken plastic pieces from other plastics and reduces the load on the blade 6. On the other hand, the plastic pieces attached to the inner wall of the crushing screen cylinder 3 are shaken off due to centrifugal force. into the crushing screen drum 3 to prevent the meshes of the crushing screen drum 3 from being blocked, and at the same time, prevent the plastic attached to the inner wall of the crushing screen drum 3 from being completely broken and improve the crushing effect.
