After screening inside the shell 1, unqualified particles remain above the screen 52, and automatically enter the discharge pipe 9 and flow into the reflux cylinder 7 during the screening process. The blower 8 is started to form an airflow from bottom to top inside the reflux cylinder 7, which transports the particles upward, enters the feed pipe 10, and flows out to the left to the grinding assembly 3 for secondary grinding.

[0031] See also Figure 2-3 The grinding assembly 3 includes a mounting frame 31, which is mounted on the upper right end of the outer shell 1 by a fixed connection. A telescopic cylinder 32 is fixedly mounted on the left side of the mounting frame 31. A first servo motor 33 is fixedly mounted on the output end of the telescopic cylinder 32. A grinding head 34 is fixedly mounted on the output end of the first servo motor 33. The grinding head 34 includes a guide plate 341 and a grinding plate 342. The guide plate 341 is located at the upper end of the grinding plate 342, and the shapes of the guide plate 341 and the grinding plate 342 are both conical, and the guide plate 341 and the grinding plate 342 are symmetrically arranged. When in use, the grinding head 34 is fixed to the middle part of the outer shell 1 by the mounting frame 31, and the lifting and lowering movement of the grinding head 34 can be controlled by the telescopic cylinder 32, thereby controlling the size of the grinding particles, and the rotation of the grinding head 34 can be controlled by the first servo motor 33 to grind the polymer material.

The guide sheet 35 can help the material enter the conical grinding cylinder 36 for rapid grinding.

[0033] See also Figure 2 and Figure 4 Two longitudinally arranged limit frames 4 are fixedly installed at the lower end of the shell 1, and a screening assembly 5 is slidably installed at the lower end of the shell 1. The screening assembly 5 includes two fixed plates 51, which are installed at the upper end of the limit frame 4 by a movable connection, and the left side of the fixed plate 51 passes through the left side wall of the shell 1, and a screen 52 is fixedly installed inside the fixed plate 51. A connecting rod 53 is fixedly installed on the left side of the fixed plate 51, and springs 54 are fixedly installed on the upper and lower ends of the right side of the connecting rod 53.

[0035] The working principle of the utility model is as follows: firstly, the grinding equipment is connected to the power supply, and the blower 8 is started to form an airflow from bottom to top inside the reflux cylinder 7. The staff can directly pour the material to be ground into the feed port 2, and the material falls on the guide sheet 35 by its own gravity. Since the inner side of the guide sheet 35 is at a low position, the material automatically enters the conical grinding cylinder 36 for grinding under the guidance of the guide sheet 35 after being poured into the shell 1 from the feed port 2. The guide sheet 35 can help the material enter the conical grinding cylinder 36 for rapid grinding. The second servo motor 552 is started to drive the cam 553 to rotate. When the cam 553 rotates, it hits the connecting rod 53 and the two fixed plates 51 to generate vibration, and then the screen 52 in the fixed plate 51 can quickly screen the ground polymer material particles. The setting of the vibration mechanism 55 can speed up the screening speed of the particles. After being screened by the two screens 52, the qualified ground particles can be directly collected in the collection drawer 6 for convenient unified processing by the staff. After screening inside the housing 1, unqualified particles remain above the screen 52, and automatically enter the discharge pipe 9 and flow into the reflux cylinder 7 during the screening process. Under the action of the blower 8, the particles are transported upward, enter the feed pipe 10, and flow out to the left to the grinding assembly 3 for secondary grinding.

[0036] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
