Description

[0002] Plastic powder, also known as plastic powder, is a granular raw material, usually used in the production of plastic products. The production process of plastic powder is an interlocking process, involving multiple links such as raw material selection, raw material pretreatment, plastic powder preparation, plastic powder processing, quality inspection, etc. In the production of plastic powder, the process of each link is crucial. Only by strictly following the process can the quality and production efficiency of plastic powder be ensured.

[0003] In the existing plastic powder processing, a crushing device is usually required to perform preliminary crushing of the granular plastic powder raw materials, and then the preliminary crushed plastic powder is ground.

Since the two crushing rollers 311 rotate in opposite directions, the mixed raw materials entering the crushing box 3 can be crushed, and the crushed raw materials can fall onto the material blocking seat 37. Since the material blocking seat 37 is composed of two inclined material blocking plates 371, the crushed raw materials falling into the material blocking seat 37 can fall downward until they fall into the grinding cylinder 32.

[0050] When the powder is completely discharged, the motor 4 346 of the cleaning mechanism 34 can be started and drive the bevel gear 2 345 to rotate. The rotation of the bevel gear 2 345 can drive the bevel gear 1 344 to rotate. When the bevel gear 1 344 rotates, the grinding cylinder 32 can be driven to rotate. The rotation of the grinding cylinder 32 can drive the powder remaining on the inner wall to rotate together.

[0051] S5, powder screening, through the cooperation of the powder delivery pump 7 and the two pipes, the powder in the crushing box 3 can be transported to the inside of the screening box 4. When the powder falls onto the screen 411, the vibration motor 417 of the screening mechanism 41 can be started to drive the screen 411 to vibrate. When the screen 411 vibrates, it can not only drive the two sliders 415 to vibrate together, but also facilitate the screen 411 to separate powders of different particle sizes. Small particles of powder can fall into the inside of the aggregate box 44 through the screen 411. When the screening work is completed, the operator can open the crushing box 3 through the existing box door, take out the collecting box 44, and the large-particle powder can move to the screening plate 412. Since the screen 411 and the screening plate 412 are both inclined, the large-particle powder can fall into the collecting box 43 through the screening plate 412 and the discharge chute 42, and the plurality of springs 416 can play a buffering role. When the large-particle powder in the collecting box 43 reaches a certain level, it can be poured into the crushing box 3 again, and the S4 operation is repeated.
