The crushing device is characterized by a vibration device located below it, comprising a filter tank below the crushing device, hollow support blocks on both sides of the filter tank, connecting rods on both sides of the top of the support blocks connected to the inner wall of the machine body, insertion rods on both sides of the filter tank inserted into the support blocks, locking blocks at both ends of the insertion rods, and springs on both sides of the filter tank near the insertion rods connected to the inner wall of the machine body. However, in the above technology, when crushing plastic, it is inconvenient to screen the crushed plastic, resulting in larger plastic particles and poor crushing effect, thus reducing the practicality of the crusher in use. Therefore, this utility model proposes a plastic crusher that prevents particle splashing to solve the above problems. Utility Model Content

[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1 , 2As shown in Figures 3 and 4, this embodiment proposes a plastic crusher to prevent particle splashing, including a crushing chamber 1, support legs 2 installed at the four corners of the bottom of the crushing chamber 1, a discharge port 3 installed at the middle position of the bottom of the crushing chamber 1, a crushing chamber 4 installed at the top of the crushing chamber 1, a feed port 5 installed at the top of the crushing chamber 4, a crushing mechanism arranged at the upper part of the inside of the crushing chamber 4, a screening mechanism arranged at the lower part of the inside of the crushing chamber 4, and a crushing mechanism arranged inside the crushing chamber 1.

[0020] The screening mechanism includes a screening plate 12, a connecting plate 13, a vibration motor 14, a telescopic rod 15, and a telescopic spring 16. The screening plate 12 is installed at the bottom inside the crushing chamber 4. Connecting plates 13 are installed on both sides of the screening plate 12, with one end of each connecting plate 13 extending to the outside of the crushing chamber 4. The vibration motor 14 is installed at the bottom inside the crushing chamber 4, and its output end is connected to the top of the screening plate 12. Telescopic rods 15 are installed on both sides inside the crushing chamber 4, with their top ends connected to the bottom of the connecting plate 13. A telescopic spring 16 is provided on the outer wall of each telescopic rod 15. The screening plate 12 has an arc-shaped design inside the crushing chamber 4, which makes material feeding more convenient during use. After the crushed plastic particles fall above the screening plate 12, the vibration motor 14 is started. With the cooperation of the telescopic rod 15 and the telescopic spring 16, the screening plate 12 and the connecting plate 13 are shaken. The screening plate 12 and the connecting plate 13 are used to screen the plastic. Larger plastic particles roll from the screening plate 12 to the top of the connecting plate 13 for discharge, while smaller plastic particles enter the crushing chamber 1 through the feed port below the crushing chamber 4. The screening plate 12 screens the initially crushed plastic, preventing larger plastic particles from entering the crushing chamber 1 through the screening plate 12. It also prevents the feed port below the crushing chamber 4 from getting clogged, allowing larger plastic particles to be crushed again, thus greatly improving the practicality of the crusher in use.

[0021] The crushing mechanism includes a mounting cavity 6, a first servo motor 7, a driving gear 8, a driven gear 9, a rotating shaft 10, and crushing teeth 11. The mounting cavity 6 is installed on one side of the crushing cavity 4. The first servo motor 7 is installed at one end of the mounting cavity 6. The driving gear 8 is installed on one side inside the mounting cavity 6. The output end of the first servo motor 7 is connected to one end of the driving gear 8. The driven gear 9 meshes with one side of the driving gear 8. The rotating shaft 10 is installed inside the crushing cavity 4. One end of the rotating shaft 10 is connected to both the driving gear 8 and the driven gear 9. One end of the wheel 9 is connected, and the outer side wall of the rotating shaft 10 is equipped with crushing teeth 11. There are two rotating shafts 10 inside the crushing chamber 4. The two rotating shafts 10 are symmetrically distributed about the central axis of the crushing chamber 4. When in use, the first servo motor 7 is started to drive the drive gear 8 to rotate. Since the drive gear 8 and the driven gear 9 mesh with each other, the drive gear 8 and the driven gear 9 are used to drive the rotating shaft 10 to rotate, and then the crushing teeth 11 are used to perform preliminary crushing of the plastic. When crushing, the feed port 5 is closed to prevent plastic particles from splashing.

[0022] The crushing mechanism includes a second servo motor 17, a first gear 18, a second gear 19, a rotating shaft 20, and crushing blades 21. The second servo motor 17 is installed at the top of the crushing chamber 1. The first gear 18 is installed at the top inside the crushing chamber 1. The output end of the second servo motor 17 is connected to one end of the first gear 18. The second gear 19 meshes with both sides of the first gear 18. The rotating shaft 20 is installed at the bottom of the second gear 19. Crushing blades 21 are arranged on the outer wall of the rotating shaft 20. Multiple crushing blades 21 are arranged on the outer wall of the rotating shaft 20, and the multiple crushing blades 21 are evenly distributed on the outer wall of the rotating shaft 20. In use, the second servo motor 17 is started to drive the first gear 18 to rotate, which in turn drives the second gear 19 to rotate. The second gear 19 drives the rotating shaft 20 to rotate, which in turn drives the crushing blades 21 to rotate. The crushing blades 21 perform secondary crushing of plastic particles, resulting in better crushing effect and higher crushing efficiency, thereby greatly improving the versatility of the crusher in use.

[0023] Working principle: The operator first places the plastic product into the crushing chamber 4 through the feed inlet 5. At this time, the first servo motor 7 is started, driving the drive gear 8 to rotate. Since the drive gear 8 and driven gear 9 mesh with each other, they drive the rotating shaft 10 to rotate, thereby using the crushing teeth 11 to perform preliminary crushing of the plastic. Closing the feed inlet 5 during crushing prevents plastic particles from splashing. The crushed plastic particles fall above the screening plate 12. At this time, the vibration motor 14 is started, and with the cooperation of the telescopic rod 15 and the telescopic spring 16, it drives the screening plate 12 and the connecting plate 13 to vibrate. The plastic is screened using the screening plate 12 and the connecting plate 13. Larger plastic particles roll off the screening plate 12 and fall onto the connecting plate 13 for discharge, while smaller plastic particles enter the crushing chamber 1 through the feed port below the crushing chamber 4. At this time, the second servo motor 17 is started to drive the first gear 18 to rotate, which in turn drives the second gear 19 to rotate. The second gear 19 drives the rotating shaft 20 to rotate, which in turn drives the crushing blade 21 to rotate. The crushing blade 21 performs secondary crushing of the plastic particles, resulting in better crushing effect. Finally, the plastic is discharged through the discharge port 3.
