Description

Technical Field

[0001] This utility model relates to the field of plastic parts recycling technology, specifically a crushing device for recycling plastic parts. Background Technology

[0002] When recycling plastics, crushing devices are often used to crush them. Then, the crushed plastics are transported to a packaging device by a conveyor to package them, thereby improving the convenience of subsequent handling.

[0003] According to a utility model patent with Chinese patent application number 202220538476.0, a crushing device for plastic recycling is mentioned. This device can prevent plastic from becoming clogged or stuck inside the transfer hopper, which would cause the plastic to move unevenly in the transfer hopper. This would result in an unstable rate at which the plastic enters the screw conveyor, thus reducing the efficiency of plastic recycling. However, this crushing device for plastic recycling does not have a screening function, and the crushed plastic is not uniform in size, resulting in poor crushing and recycling effect. Therefore, it is necessary to propose a crushing device for plastic recycling to solve the problems mentioned above. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a crushing device for recycling plastic parts. The device has the advantage of screening function, which makes the crushing effect on feed obvious, thus solving the problem that the prior art does not have plastic screening function.

[0005] To achieve the goal of enabling the above-mentioned equipment to have a screening function and thus significantly improve the crushing effect on feed, this utility model provides the following technical solution: a crushing device for recycling plastic parts, including a crushing box, a filter box fixedly installed at the bottom of the crushing box, a support frame fixedly installed at the bottom of the filter box, a pushing component and a crushing component movably installed inside the crushing box, and a filter screen fixedly installed inside the filter box;

[0006] The feeding assembly includes a hydraulic lifting rod. The top of the crushing box is provided with a hydraulic lifting rod. A connecting plate is fixedly connected to the output shaft of the hydraulic lifting rod. A drive motor is fixedly installed at the bottom of the connecting plate. A first gear is installed at the output shaft of the drive motor. A second gear meshes with the outer surface of the first gear. A plug-in rod is provided inside the second gear. A rotating plate is provided outside the plug-in rod.

[0007] Furthermore, a socket rod is fixedly connected to the bottom of the connecting plate, and the plug rod is sleeved inside the socket rod.

[0008] Furthermore, the crushing assembly includes a first bevel gear, which is movably installed inside the crushing box. A second bevel gear meshes with each other on the outer surface of the first bevel gear. A crushing rotating rod is fixedly connected to the bottom of the second bevel gear, and crushing teeth are provided on the outside of the crushing rotating rod.

[0009] Furthermore, a screw conveyor is fixedly installed on the left side of the support frame, and a conveying device is movably installed at the bottom of the filter box, with the filter box connected to the screw conveyor.

[0010] Furthermore, a motor housing is fixedly installed on the front of the crushing box, and the bottom of the plug rod is sleeved on the top of the lifting plate.

[0011] Furthermore, an electric telescopic rod is fixedly connected to the right side of the filter box, and a push plate is fixedly connected to the output shaft of the electric telescopic rod. The push plate is slidably installed on the top of the filter screen. A connecting rod is provided on the outside of the sleeve rod, and a limit slider is provided on the side of the lifting plate. The limit slider is slidably installed on the inner wall of the filter box.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] This plastic recycling crushing device, by setting up crushing components, operates by starting the motor box, which drives the first bevel gear and the second bevel gear to mesh with each other, thereby driving the crushing rod and crushing teeth to rotate, thus crushing the plastic fed into the crushing box. The crushed plastic is filtered through a filter screen to filter out smaller, uniformly sized plastics. Larger plastics are not convenient for further recycling and processing. Finally, the plastics are conveyed by a conveying device.

[0014] This plastic parts recycling crushing device, equipped with a pushing assembly, operates by activating a hydraulic lifting rod. When the output shaft of the hydraulic lifting rod retracts, it drives a drive motor to descend via a connecting plate. This, in turn, lowers a connecting rod and a lifting plate. Once the lifting plate is away from the bottom of the crushing chamber, some of the crushed plastic falls into a filter box, while some falls to the top of the lifting plate. Activating the drive motor then engages a first and second gear at its output shaft, causing the connecting rod and rotating plate to rotate. This pushes the plastic onto the filter screen for filtration, facilitating screening and preventing larger pieces from affecting the quality of further recycling. Attached Figure Description

A plug-in rod 707 is provided inside the second gear 705. A rotating plate 708 is provided outside the plug-in rod 707.

[0023] In the implementation of the case, by setting up the crushing component 14, when in use, by starting the motor box 6, the motor box 6 drives the first bevel gear 141 and the second bevel gear 142 to mesh with each other, thereby driving the crushing rod 143 and the crushing teeth 144 to rotate, so as to crush the plastic put into the crushing box 1. Furthermore, through the filter screen 11, the smaller plastic with uniform size can be filtered. The larger plastic is not convenient for further recycling and processing. Finally, the plastic is conveyed by the conveying device 5.

[0024] In the implementation of the case, by setting up the material pushing component 7, when in use, by activating the hydraulic lifting rod 701, when the output shaft of the hydraulic lifting rod 701 retracts, it will further drive the drive motor 703 to descend through the connecting plate 702, thereby driving the sleeve rod 8 and the lifting plate 9 to descend through the connecting plate 702. After the lifting plate 9 moves away from the bottom of the crushing box 1, the crushed plastic part inside the crushing box 1 falls into the filter box 2, and part falls to the top of the lifting plate 9.

[0025] In the implementation of the case, by starting the drive motor 703, the output shaft of the drive motor 703 drives the first gear 704 and the second gear 705 to mesh with each other, thereby driving the plug rod 707 and the rotating plate 708 to rotate, so as to push the plastic onto the filter screen 11 for filtration, which facilitates the screening of plastic and avoids larger plastics from affecting the quality of further recycling and processing.

[0026] In the case implementation, by setting up a screw conveyor 4, it is convenient to further convey larger pieces of broken plastic to the crushing box 1 for further crushing, so that the plastic can be crushed and recycled evenly.

[0027] When implementing this procedure, please follow these steps:

[0028] 1) First, put the plastic into the crushing box 1;

[0029] 2) Then the plastic inside the crushing box 1 is crushed by the crushing component 14;

[0030] 3) The crushed plastic is then fed into the crushing box 1 for filtration via the feeding component 7;

[0031] 4) Finally, part of the plastic is conveyed back to the crushing box 1 for filtration by the screw conveyor 4, and the other part is filtered by the filter screen 11 and then conveyed by the conveyor 5.

[0032] In summary, this plastic recycling crushing device, by setting up the crushing component 14, in use, by starting the motor box 6, the motor box 6 drives the first bevel gear 141 and the second bevel gear 142 to mesh with each other, thereby driving the crushing rotating rod 143 and the crushing teeth 144 to rotate, so as to crush the plastic put into the crushing box 1. Furthermore, the filter screen 11 can filter out the smaller plastic pieces with uniform size. Larger plastic pieces are not convenient for further recycling and processing. Finally, the plastic is conveyed by the conveying device 5.

[0033] Furthermore, by setting up the feeding assembly 7, when in use, by activating the hydraulic lifting rod 701, when the output shaft of the hydraulic lifting rod 701 retracts, it will further drive the drive motor 703 to descend via the connecting plate 702. In turn, the connecting plate 702 will drive the sleeve rod 8 and the lifting plate 9 to descend. After the lifting plate 9 moves away from the bottom of the crushing box 1, the crushed plastic part inside the crushing box 1 falls into the filter box 2, and part falls to the top of the lifting plate 9. By activating the drive motor 703, the output shaft of the drive motor 703 drives the first gear 704 and the second gear 705 to mesh with each other, thereby driving the plug rod 707 and the rotating plate 708 to rotate, so as to push the plastic onto the filter screen 11 for filtration, which facilitates the screening of plastic and avoids larger plastics from affecting the quality of further recycling and processing.
