[0021] Hereinafter, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art.

[0022] See Figures 1-5 , a plastic product waste crushing and recycling device provided by an embodiment of the present utility model includes a recycling box body 1. Inside the recycling box body 1, a conveyor belt 7, a first crushing cutter group 6, a second crushing cutter group 14, a conveyor auger 5, and an arc-shaped filter screen plate 4 are respectively connected. Above the arc-shaped filter screen plate 4, there is a conveyor auger 5. Above the conveyor auger 5, there are a first crushing cutter group 6 and a second crushing cutter group 14, and the first crushing cutter group 6 and the second crushing cutter group 14 are arranged side by side. The conveyor belt 7 is arranged above the first crushing cutter group 6 and the second crushing cutter group 14. At the top end of the recycling box body 1, a support frame 11 is fixedly connected, and a hydraulic cylinder 9 is fixedly connected to the support frame 11. The hydraulic rod on the hydraulic cylinder 9 passes downward through the support frame 11 and is fixedly connected to a cutter holder 10. The cutter holder 10 is located above the conveyor belt 7. Inside the recycling box body 1, there is also a limiting plate 8 fixedly connected to limit and support the conveyor belt 7. The limiting plate 8 is arranged inside the conveyor belt 7. At the lower side of the recycling box body 1, a discharge port 2 is fixedly connected.

[0023] During the use of the utility model, the waste plastic products that have been cleaned and removed of other impurities are poured into the recycling box body 1 and fall on the conveyor belt 7. The conveyor belt 7 drives the waste plastic products to move leftward. When the waste plastic products move below the cutter holder 10, the hydraulic cylinder 9 is operated, which drives the cutter holder 10 to move downward and cut the waste plastic products. At the same time, the conveyor belt 7 is supported by the limit plate 8 to prevent the conveyor belt 7 from deforming excessively under pressure. Then, the cut waste plastic products continue to move leftward. After moving to the leftmost side, the waste plastic products fall off the conveyor belt 7 and land on the first crushing cutter group 6 and the second crushing cutter group 14. At this time, the waste plastic products are crushed again by the operation of the first crushing cutter group 6 and the second crushing cutter group 14. Then, the crushed waste plastic products continue to move downward and land on the arc-shaped filter plate 4. At this time, the conveyor auger 5 is operated to drive the waste plastic products to move back and forth. Then, the fine waste plastic products pass through the arc-shaped filter plate 4 and fall into the lower part of the recycling box body 1, and move downward along the guide inclined plate 3. Finally, they are discharged and recycled through the discharge port 2. The waste that cannot pass through the arc-shaped filter plate 4 is discharged by opening the arc-shaped door plate 13 on the connecting pipe 12. At this time, the conveyor auger 5 drives the waste to move rightward, and the waste can be discharged through the opening on the connecting pipe 12, collected by an external collection device, and then imported into the recycling box body 1 for secondary waste crushing.

[0024] As Figure 1 shown, two guide inclined plates 3 are fixedly connected inside the recycling box body 1. Both of the two guide inclined plates 3 are located below the arc-shaped filter plate 4 and are symmetrically arranged on both sides of the discharge port 2, facilitating the guiding of the screened waste plastic products and facilitating the discharge of the waste through the discharge port 2 from the recycling box body 1.

[0025] As Figure 4 and Figure 5 shown, a partition plate 15 is fixedly connected to the inner top of the recycling box body 1. A plurality of opening slots 151 are formed on the partition plate 15. The cutter section at the lower part of the cutter holder 10 passes downward through the opening slots 151, facilitating the extrusion of the waste plastic products clamped on the cutter holder 10 when the cutter holder 10 resets.

[0026] As Figure 1 shown, a connecting pipe 12 is fixedly connected to the right side of the recycling box body 1. The inner side wall of the connecting pipe 12 is rotatably connected to one end of the conveyor auger 5 through a bearing. An opening is formed on the lower side of the connecting pipe 12, and an arc-shaped door plate 13 is arranged inside the opening. One end of the arc-shaped door plate 13 is rotatably connected to the connecting pipe 12 through a hinge, and the other end is connected to the connecting pipe 12 through an openable lock. The connecting pipe 12 can stably support the conveyor auger 5. Through the design of the opening and the arc-shaped door plate 13, the waste plastic products that cannot be filtered can be discharged and subjected to secondary crushing.

[0027] As shown Figure 1 in the figure, the other end of the conveying auger 5 is rotatably connected to the recycling box body 1 through a bearing, and a servo motor is fixedly connected to the left side surface of the recycling box body 1. The output shaft of the servo motor is connected to the conveying auger 5. The operation of the servo motor can drive the conveying auger 5 to rotate forward and backward, which is convenient for moving the crushed plastic product waste back and forth.

[0028] As shown Figure 2 in the figure, two driving motors are fixedly connected to the left side surface of the recycling box body 1, and the output shafts of the two driving motors are respectively connected to the first crushing knife group 6 and the second crushing knife group 14, and the first crushing knife group 6 and the second crushing knife group 14 are driven respectively by the driving motors. The operation of the driving motors can drive the first crushing knife group 6 and the second crushing knife group 14 to rotate. Through the rotation of the first crushing knife group 6 and the second crushing knife group 14, the dropped plastic product waste can be finely crushed.

[0029] As shown Figure 1 in the figure, a scraper holder is fixedly connected to the inner right wall of the recycling box body 1, and the top of the scraper holder is closely attached to the lower side surface of the conveyor belt 7. The design of the scraper holder can scrape off the plastic product waste attached to the surface of the conveyor belt 7.

[0030] The above are only the embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
