[0010] Thus, the crushing chamber is equipped with crushing rollers, which is a structure common to existing crushers. A protective cover is fixed to the crushing chamber to prevent plastic from splashing outwards during the crushing process. When feeding is required, two feeding components enter the protective cover sequentially under the action of the moving structure to add the material to be crushed to the crusher. When one feeding component is inside the protective cover, the other feeding component is in the process of adding the material to be crushed, thereby improving the crushing efficiency.

[0011] The feeding assembly includes a material box and an outer plate. The material box has a material trough with an opening on one side. An outer plate is fixed to the outer end of the material box. The outer plate is fixedly connected to the drive plate via an outer rod. A drive motor is fixedly installed on the outer plate. The output shaft of the drive motor passes through the outer plate and is fixedly connected to the drive plate. The outer plate has sliding holes that can slide with three sliding rods.

[0012] Inner discs are rotatably mounted on both sides of the transmission plate. The inner discs are connected to the driven discs via inner rods, and the driven discs are fixedly connected to the material trough.

In the description of the present invention, it should be understood that directional terms such as "upper," "lower," "top," and "bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of the present invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0022] like Figure 1-4As shown, a plastic crusher includes a crushing box 1, a bracket is fixedly installed at the lower end of the crushing box, two crushing rollers are rotatably installed inside the crushing box, one end of the crushing roller passes through the crushing box and is fixedly connected to the output shaft of the crushing motor 2, the crushing motor is fixedly installed on the crushing box, and a crushing port is opened at the upper end of the crushing box;

[0023] A protective cover 3 is fixedly installed on the crushing box, and the crushing port is located inside the protective cover; a slide 4 is fixedly installed on both sides of the protective cover, and the protective cover has a sliding groove. The two slides are fixedly connected by three slide rods 5, and the slide rods pass through the sliding grooves; two feeding components 6 are slidably installed on the slide rods, and the two feeding components are connected by a transmission plate 7. The transmission plate slides with the slide rods, and a moving structure is provided on the outside of the protective cover to drive the feeding components to move along the slide rods.

[0024] Thus, the crushing chamber is equipped with crushing rollers, which is a structure common to existing crushers. A protective cover is fixed to the crushing chamber to prevent plastic from splashing outwards during the crushing process. When feeding is required, two feeding components enter the protective cover sequentially under the action of the moving structure to add the material to be crushed to the crusher. When one feeding component is inside the protective cover, the other feeding component is in the process of adding the material to be crushed, thereby improving the crushing efficiency.

[0025] In implementation, the feeding assembly includes a material box 8 and an outer plate 9. The material box has a material trough with an opening on one side. An outer plate 10 is fixed to the outer end of the material box. The outer plate is fixedly connected to the drive plate 12 via an outer rod 11. A drive motor 13 is fixedly installed on the outer plate. The output shaft of the drive motor passes through the outer plate and is fixedly connected to the drive plate. The outer plate has sliding holes that can slide with three sliding rods.

[0026] Inner discs 14 are rotatably mounted on both sides of the transmission plate. The inner discs are connected to the driven disc 16 via inner rods 15. The driven disc is fixedly connected to the material trough.

[0027] Two feeding components are connected by a transmission plate. The distance between the outer plate and the transmission plate matches the size of the protective cover. When the material trough is inside the protective cover, the outer plate and the transmission plate block the sliding groove of the protective cover, preventing plastic splattering. During feeding, the material to be crushed is located in the material trough with its opening facing upwards. The moving structure drives the feeding components to move, and the material trough moves into the protective cover. The drive motor drives the drive disc, outer rod, outer disc, material trough, driven disc, inner rod, and inner disc to rotate synchronously. The material trough flips downwards, causing the material to fall into the crushing inlet, where it is crushed by two crushing rollers. The synchronous movement of the two feeding components improves efficiency.

[0028] In implementation, the moving structure includes a hydraulic cylinder 17 fixedly installed on one side of the protective cover. The cylinder rod is fixedly connected to a connecting block 18, and the connecting block is fixedly connected to the outer plate of one of the feeding components. The connection between the hydraulic cylinder and one of the outer plates enables the synchronous movement of the two feeding components.

[0029] In practice, inclined guide plates are fixedly installed on both sides of the inner side of the protective cover, and the inclined guide plates are inclined downwards towards the crushing inlet. This facilitates the guidance of the material to be crushed, allowing the material to enter the crushing inlet more effectively.

[0030] During implementation, an observation window 19 is installed on the protective cover to facilitate observation of the internal situation.

[0031] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
