[0002] The crushing of waste plastics refers to the process of reducing the size of materials. It is usually completed by using various types of crushing machinery to apply different mechanical forces to the materials, such as tensile force, extrusion force, impact force and shear force. Waste plastics are complex in shape and of different sizes, especially some large waste products. They must be crushed, ground or sheared to break them into fragments or small pieces of a certain size before they can be recycled or further molded into various recycled products.

[0003] However, when it comes to the actual crushing of waste plastics, many production workshops still rely mainly on manual feeding. The amount of material fed is difficult to control, which can easily cause excessive amounts of material to accumulate at the feed inlet, reducing the practicality of the device and generating smoke and dust during feeding. The smoke and dust will float into the air and pollute the air. Utility Model Content

The adjacent moving components 7 are connected by fixed rods to enhance the stability of the moving components 7. The moving components 7 include a second partition plate 72 and two fixed blocks 73. A plurality of first springs are arranged inside the second partition plate 72. A first partition plate 71 is slidably arranged inside the second partition plate 72. One end of the first spring is fixedly connected to the first partition plate 71. The two fixed blocks 73 are fixedly connected to the second box body 2. A second spring is fixedly arranged inside the fixed block 73. One end of the second partition plate 72 is slidably arranged in the fixed block 73, and the second partition plate 72 is fixedly connected to the second spring.

[0027] Combination Figure 4 A protective shell is provided on the outside of the first box body 1, and a second motor 8 is fixedly provided inside the protective shell. A rotating plate 9 is fixedly connected to the output end of the second motor 8. A moving frame 10 is slidably provided on the outside of the first box body 1, and a moving shaft is fixedly provided at one end of the rotating plate 9, and one end of the moving shaft is provided in the moving frame 10. Moving blocks are fixedly provided on both sides of the moving frame 10. A groove for moving the moving block is provided on the outside of the first box body 1.

[0028] Embodiment 2: In the present utility model, the specific working principle of crushing waste plastics for feeding is as follows:

[0029] First, the discharge pipe on the top of the third box body 3 is opened, and the waste plastics are poured in from the discharge pipe. After the pouring is completed, the discharge pipe is closed to prevent smoke and dust from escaping.

[0030] Then, when crushing is required, the first motor 4 and the second motor 8 are started, and the second motor 8 drives the rotating plate 9 to rotate. Since a connecting rod is fixedly provided at one end of the rotating plate 9 and one end of the connecting rod is arranged in the moving frame 10, when the rotating plate 9 rotates, the moving frame 10 will be driven to move left and right, and the moving frame 10 will drive the moving plate 11 to move left and right.

[0031] When the moving plate 11 moves toward two of the moving components 7 , the moving plate 11 will squeeze the first partition plate 71 and the second partition plate 72 , so that the opening for unloading materials will leak out, and the waste plastics can fall from the opening and fall into the first box body 1 .

[0032] Then, the first motor 4 drives the crushing roller 51 to rotate and crush the waste plastics, so that the movable plate 11 moves left and right, and alternately squeezes the movable component 7 to make the opening leak out. In this way, alternating feeding makes it easy to control the amount of feeding.

[0033] Finally, after the crushing is completed, the discharge pipe is opened to facilitate the collection of the crushed waste plastics.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
