The powder coating entering the grinding box 1 is subjected to strong shearing, impact and grinding under the interaction between the grinding column 8 and the grinding plate 6, and is gradually refined. The "W"-shaped design of the partition 4 allows the material to flow along a specific path during the grinding process. At the same time, the setting of the flow holes helps to evenly distribute the material and improve the grinding efficiency. The ground powder falls onto the sieve plate 5 through the discharge port at the bottom of the grinding plate 6. The sieve plate 5 sieves the ground powder, and the qualified powder falls into the receiving box 2 through the screen. The close fit between the grinding column 8 and the grinding plate 6, as well as the guiding effect of the partition 4, allows the material to be more fully ground during the grinding process, thereby improving the grinding efficiency.

[0026] In this embodiment, if Figures 1 to 4As shown, the connecting rod assembly is used to realize the rapid vibration screening of the material. The connecting rod assembly is connected to the grinding assembly. The connecting rod assembly includes a driving wheel fixedly connected to the output shaft of the grinding motor 7. The internal rotation of the grinding box 1 is connected to the transmission rod 10. The external part of the transmission rod 10 is fixedly connected to the driven wheel. The driven wheel and the driving wheel are connected by a transmission belt 9. The external part of the transmission rod 10 is fixedly connected to the first bevel gear 11. The internal rotation of the grinding box 1 located above the screen plate 5 is connected to the driving rod 13. One end of the driving rod 13 is fixedly connected to the second bevel gear 12. The bottom of the second bevel gear 12 is meshed with one side of the first bevel gear 11. The external part of the driving rod 13 is symmetrically fixedly connected to two half-toothed discs 1 4. Two fixed rods 15 are symmetrically fixedly connected to the inner wall of the grinding box 1, and one end of the two fixed rods 15 is fixedly connected to a sliding block 16. The outside of the sliding block 16 is slidably connected to a rack 17, and the bottom of the rack 17 is fixedly connected to a knocking disk 18. The rack 17 is provided with a tooth pattern on the side facing the half-toothed disk 14, and the side of the rack 17 facing the half-toothed disk 14 is meshed with the tooth pattern of the half-toothed disk 14. The inside of the rack 17 is fixedly connected to a guide rod, and the sliding block 16 is slidably connected to the outside of the guide rod. A spring is fixedly connected between the bottom of the sliding block 16 and the bottom of the inner cavity of the rack 17, and the spring is sleeved on the outside of the guide rod. The knocking disk 18 is located just above the sieve plate 5. When the grinding motor 7 is started, its output shaft starts to rotate, and the fixed The driving wheel fixed on the output shaft of the grinding motor 7 rotates accordingly, and through the transmission belt 9, the driving wheel transmits power to the driven wheel on the transmission rod 10, so that the transmission rod 10 also starts to rotate, and the rotation of the transmission rod 10 drives the No. 1 bevel gear 11 to rotate. The No. 1 bevel gear 11 and the No. 2 bevel gear 12 are meshed with each other, so the No. 2 bevel gear 12 also rotates accordingly, and then drives the driving rod 13 to rotate. The two half-toothed discs 14 fixed to the outside of the driving rod 13 rotate with the rotation of the driving rod 13. Since the teeth on the rack 17 are meshed with the teeth of the half-toothed disc 14, when the teeth of the half-toothed disc 14 contact the rack 17, it will push the rack 17 to move up and down along the guide rod. When the teeth of the half-toothed disc 14 are separated from the rack 17, the gear The bar 17 is quickly reset under the action of the spring, and the up and down movement of the rack 17 drives the knocking plate 18 to vibrate. The knocking plate 18 is located directly above the screen plate 5. Its vibration causes the material on the screen plate 5 to be impacted, thereby promoting the rapid screening of the material. The periodic vibration of the knocking plate 18 effectively avoids the accumulation of material on the screen plate 5, so that the material can be evenly distributed and pass through the screen quickly, thereby significantly improving the screening efficiency. The vibration effect makes the screening process more sufficient, which helps to screen out more qualified powder and reduce the proportion of unqualified products. The connecting rod assembly cleverly utilizes the power of the grinding motor 7, and realizes the transmission and conversion of power through the transmission mechanism and bevel gears, making the entire equipment compact and highly integrated.

[0027] The working principle provided by the utility model is that the powder coating enters the grinding box 1 through the feed channel 3, the grinding motor 7 is started, driving the grinding column 8 to rotate at high speed, and the grinding column 8 is tightly fitted with the inner wall of the grinding plate 6 to form a grinding area. The powder coating entering the grinding box 1 is subjected to strong shearing, impact and grinding under the interaction between the grinding column 8 and the grinding plate 6, and is gradually refined. The "W" shape design of the partition 4 allows the material to flow along a specific path during the grinding process. At the same time, the setting of the flow holes helps to evenly distribute the material and improve the grinding efficiency. The ground powder falls onto the sieve plate 5 through the discharge port at the bottom of the grinding plate 6. The sieve plate 5 screens the ground powder, and the qualified powder falls into the receiving box 2 through the screen. When the grinding motor 7 is started, its output shaft starts to rotate, and the driving wheel fixed on the output shaft of the grinding motor 7 rotates accordingly. Through the transmission belt 9, the driving wheel transmits power to the driven wheel on the transmission rod 10, so that the transmission rod 10 also starts to rotate. The rotation of the transmission rod 10 drives the No. 1 bevel gear 11 to rotate, and the No. 1 bevel gear 11 and the No. 2 bevel gear 12 are meshed with each other, so the No. 2 bevel gear 12 also rotates, which in turn drives the driving rod 13 to rotate. The two half-toothed discs 14 fixed to the outside of the driving rod 13 rotate with the rotation of the driving rod 13. Since the teeth on the rack 17 are meshed with the teeth of the half-toothed disc 14, when the teeth of the half-toothed disc 14 contact with the rack 17, they will push the rack 17 to move up and down along the guide rod. When the teeth of the half-toothed disc 14 are separated from the rack 17, the rack 17 is quickly reset under the action of the spring. The up and down movement of the rack 17 drives the knocking plate 18 to vibrate. The knocking plate 18 is located just above the screen plate 5. Its vibration causes the material on the screen plate 5 to be impacted, thereby promoting the rapid screening of the material. The periodic vibration of the knocking plate 18 effectively avoids the accumulation of material on the screen plate 5, so that the material can be evenly distributed and pass through the screen quickly, thereby significantly improving the screening efficiency.
