[0023] Specifically, the grinding assembly 3 includes a motor 301, with a pulley 302 fixedly mounted on the output end of the motor 301. A shaft 303 is rotatably mounted on the end of the grinding barrel 2 near the support frame 1. A pulley 304 is fixedly mounted on the end of the shaft 303 away from the grinding barrel 2. A transmission belt 305 is provided between the pulley 302 and the pulley 304. A guide block 306 and a limiting plate 307 are fixedly mounted on the end of the shaft 303 away from the pulley 304. A threaded hole 308 is provided on the outer wall of the limiting plate 307. A grinding disc 309 is provided on the end of the shaft 303 away from the pulley 304. A groove 310, a guide groove 311, and a threaded hole 312 are provided on the outer wall of the grinding disc 309. A bolt 313 is threadedly connected to the outer wall of the grinding disc 309. The center lines of the grinding disc 309 and the shaft 303 are located on the same vertical line. The advantage is that when the operator starts the motor 301, the output end of the motor 301 rotates, which drives the rotating shaft 303 to rotate through the cooperation of pulley 302, pulley 304 and transmission belt 305. The rotation of the rotating shaft 303 drives the grinding disc 309 to rotate, which can realize the rapid grinding of plastic materials.

[0024] Specifically, the rotating shaft 303 is adapted to the groove 310, the guide block 306 and the guide groove 311 are plugged in, and the grinding disc 309 abuts against the limiting plate 307. The advantage is that when the operator inserts the rotating shaft 303 into the groove 310 and simultaneously inserts the guide block 306 into the guide groove 311, causing the grinding disc 309 to abut against the limiting plate 307, rapid positioning of the grinding disc 309 is achieved, ensuring the accuracy of its position during installation. Furthermore, it ensures that the grinding disc 309 remains stable during high-speed rotation, preventing shaking or displacement.

[0025] Specifically, bolt 313 extends through threaded hole 312 into threaded hole 308. Threaded hole 312 has the same diameter as threaded hole 308. Multiple bolts 313 are arranged in a ring. The advantage is that after quickly positioning the grinding disc 309, the operator can quickly fix the grinding disc 309 by extending the bolts 313 through threaded hole 312 into threaded hole 308. After prolonged use, this facilitates maintenance or replacement. The multiple bolts 313 further enhance the stability of the grinding disc 309. Example 2

[0026] like Figure 2-6 As shown, as an improvement on the previous embodiment, to further improve the quality of the plastic powder, specifically, multiple identical filter holes 4 are provided, and the multiple filter holes 4 are distributed at equal intervals. The advantage is that, through the design of multiple filter holes 4, the ground plastic powder can be accurately screened. Plastic powder that meets the particle size requirements can pass smoothly through the filter holes 4, while larger particles that do not meet the standard will be intercepted in the grinding barrel 2 and continue to be ground, greatly improving the quality of the plastic powder.

[0027] Specifically, positioning block 6 and positioning slot 12 are connected by a plug-in joint, and positioning block 13 and positioning slot 7 are also connected by a plug-in joint. The advantage is that when the operator inserts positioning block 6 into positioning slot 12 and simultaneously inserts positioning block 13 into positioning slot 7, the material discharge port 11 can be quickly positioned.

[0028] Specifically, the chute 8, the through groove 14, and the limiting groove 9 are connected, and the limiting block 10 extends through the through groove 14 into the interior of the limiting groove 9. The advantage is that after the discharge port 11 is quickly positioned, the operator can slide the limiting block 10, so that the limiting block 10 extends through the through groove 14 into the interior of the limiting groove 9, which can quickly limit the discharge port 11. After long-term use, it is easy to clean or replace.

[0029] Working principle: During installation, the operator inserts the rotating shaft 303 into the groove 310 and the guide block 306 into the guide groove 311, causing the grinding disc 309 to abut against the limiting plate 307. This allows for rapid positioning of the grinding disc 309, ensuring its accurate placement during installation and maintaining stability during high-speed rotation without shaking or shifting. After quickly positioning the grinding disc 309, the operator inserts bolts 313 through threaded holes 312 and 308 to quickly fix the grinding disc 309, facilitating maintenance or replacement after prolonged use. The multiple bolts 313 further enhance the stability of the grinding disc 309. Subsequently, the operator inserts positioning block 6 into positioning groove 12 and positioning block 13 into positioning groove 7, achieving rapid positioning of the discharge port 11. After the feeding port 11 is quickly positioned, the operator slides the limiting block 10, which extends through the through groove 14 into the interior of the limiting groove 9, thus quickly limiting the feeding port 11. After long-term use, it is easy to clean or replace. When in use, the operator starts the motor 301. The output end of the motor 301 rotates, which drives the rotating shaft 303 to rotate through the cooperation of the pulley 302, the pulley 304 and the transmission belt 305. The rotation of the rotating shaft 303 drives the grinding disc 309 to rotate, which can realize the rapid grinding of plastic materials. Then the plastic powder passes through the filter hole 4 into the interior of the feeding port 11 and is discharged through the feeding port 11. Through the design of multiple filter holes 4, the ground plastic powder can be accurately screened. Plastic powder that meets the particle size requirements can pass smoothly through the filter hole 4, while those particles that are larger and do not meet the standard will be intercepted in the grinding barrel 2 and continue to be ground, which greatly improves the quality of plastic powder.
