[0055] The crushing assembly 6 comprises:

[0056] The motor 61 is arranged on the right side of the crushing box 1. The output end of the motor 61 is fixedly mounted with a first shaft 62. The first shaft 62 and an end away from the motor 61 movably penetrate the right side of the crushing box 1 and extend to the inner wall of the crushing box 1 to be rotatably connected through a bearing.

[0057] A first gear 63 is fixedly sleeved on an outer wall of the first shaft 62, and the first gear 63 is meshed with a second gear 64;

[0059] There are two mounting rollers 66, which are fixedly mounted on the outer walls of the first shaft 62 and the second shaft 65 respectively;

[0060] The arc plate 69 is slidably arranged at the lower position with the arc groove 68 opened on the outer wall of the mounting roller 66. The arc plate 69 is slidably sleeved with an arc rod 610. The two ends of the arc rod 610 are fixedly installed with the inner wall of the arc groove 68. The outer wall of the arc plate 69 is fixedly installed with a crushing knife 67.

[0061] In the specific implementation process, the first shaft 62 is rotated by starting the motor 61, and the second shaft 65 can be rotated together under the setting of the first gear 63 and the second gear 64, so that the two mounting rollers 66 have a tendency to rotate in opposite directions, and finally the crushing knife 67 installed on the surface of the mounting roller 66 can crush the plastic.

[0064] Example 2: Based on the above embodiment, the extrusion assembly 76 includes:

[0065] A driving wheel 71, a belt 72, and a driven wheel 73, wherein the driving wheel 71 is connected to the driven wheel 73 through the belt 72;

[0066] The driving wheel 71 is fixedly mounted on the outer wall of the second shaft 65;

[0067] The outer wall of one end of the third shaft 74 is fixedly mounted on the inner wall of the driven wheel 73, and the other end of the third shaft 74 movably penetrates the side of the feed box 2 and extends to the inner wall of the feed box 2 to be rotatably connected through a bearing;

[0068] The squeezing roller 75 is fixedly sleeved on the outer wall of the third shaft 74 .

[0069] In the specific implementation process, the second shaft 65 can rotate to make the driving wheel 71, the belt 72, and the driven wheel 73 rotate together. The rotation of the driven wheel 73 can make the third shaft 74 rotate, and finally the extrusion roller 75 and the extrusion plate 76 rotate to extrude the incoming plastic, thereby facilitating the crushing work of the crushing assembly 6.

[0070] In this embodiment, an extrusion plate 76 is fixedly installed on the outer wall of the extrusion roller 75. There are four extrusion plates 76, and the four extrusion plates 76 are evenly distributed on the outer wall of the extrusion roller 75. By installing on four extrusion plates 76, not only is it convenient to extrude the plastic, but the plastic can also be squeezed between the two installation rollers 66, thereby strengthening the crushing force of the crushing knife 67 on the plastic.

[0071] Example 3: Based on the above embodiment, the circulating crushing component 8 includes:

[0072] The screen frame 81 is arranged below the mounting roller 66, and a discharge port is provided on the bottom surface of the screen frame 81;

[0073] Among them, a material discharge plate 4 is arranged below the screen frame 81, and the material discharge plate 4 is fixedly arranged with the rectangular opening opened at the bottom of the crushing box 1;

[0074] The auxiliary block 82 is fixedly mounted on the side of the screen frame 81. The auxiliary block 82 is movably sleeved with a columnar rod 84. The bottom end of the columnar rod 84 is fixedly mounted on the bottom of the inner wall of the crushing box 1.

[0075] The second spring 85 is sleeved on the outer wall of the columnar rod 84, the top end of the second spring 85 is fixedly mounted on the bottom surface of the auxiliary block 82, and the bottom end of the second spring 85 is fixedly mounted on the bottom of the inner wall of the crushing box 1;

[0076] The cam 83 is fixedly sleeved on the outer wall of the first shaft 62 , and the length of the cam 83 is greater than the distance between the lower surface of the first shaft 62 and the top surface of the screen frame 81 , so that the cam 83 can be smoothly squeezed onto the screen frame 81 during the rotation process.

[0077] In the specific implementation process, the cam 83 can be rotated together with the rotation of the first shaft 62, and the cam 83 can be squeezed to the screen frame 81. Due to the second spring 85, the screen frame 81 can have an up and down vibration effect, which can not only make the crushed plastics that meet the conditions be discharged from the bottom of the screen frame 81, but also make the plastics that do not meet the conditions vibrate upward due to the vibration, contact with the crushing knife 67, and then be crushed, and this process is repeated to enhance the crushing efficiency.

[0078] Working principle: before the plastic enters the feed box 2, the motor 61 is started first. When the motor 61 is started, the first shaft 62 can be rotated. When the first shaft 62 rotates, the first gear 63 can be rotated, and then the second gear 64 can be rotated. When the first gear 63 and the second gear 64 rotate, the first shaft 62 and the second shaft 65 can be rotated, and have opposite rotation trends. At this time, the arc plate 69 can be rotated to realize the crushing knife 67 to crush the plastic. Under the setting of the driving wheel 71, the belt 72 and the driven wheel 73, the third shaft 74 can be rotated, and finally the squeezing roller 75 can be rotated. , the extrusion plate 76 rotates to extrude the plastic for easy crushing. At the same time, the extruded plastic can also be squeezed again to the crushing knife 67 to promote the crushing force. The cam 83 can rotate under the rotation of the first shaft 62. During the rotation of the cam 83, the screen frame 81 can be squeezed. Then, under the setting of the second spring 85, the screen frame 81 can vibrate up and down, so that the crushed plastic can be screened out, and the plastic that has not been screened out will continue to be crushed by the crushing knife 67 with the up and down vibration. This is repeated to strengthen the crushing force. The crushed and screened plastic will be discharged through the discharge plate 4.
