Description

Technical Field

[0001] The utility model belongs to the technical field of cosmetic production, in particular to a fine grinding device for powder cosmetic production. Background Art

[0002] Powder cosmetics include makeup powder blocks, scented powder, talcum powder, prickly heat powder, foot bath salts, bath salts and other decorative and powder cosmetics, etc. Powder cosmetics have relatively high requirements on the degree of fineness during the production process.

[0003] The utility model with publication number CN218872328U discloses a fine grinding device for powder cosmetic production and processing, including a processing box, two first through holes are provided on both sides of the processing box, four first through holes are symmetrically distributed, and the four first through holes are grouped in pairs. A through groove is provided on one side of the processing box, a feed hopper is fixedly connected to the top of the processing box, a fixed plate is fixedly connected to one side of the processing box, and a guide plate is fixedly connected to the inside of the processing box. In the above application document, one of the pulleys is driven to rotate by a motor, and when the pulley rotates, the other pulley is driven to rotate by a V-belt. At this time, the two pulleys will drive the corresponding grinding rollers to rotate, and the two grinding rollers use the grinding beads on the bodies to cooperate with each other to finely grind the cosmetics. When the two grinding rollers grind the fallen cosmetic raw materials, some of the cosmetic raw materials that are not completely polished will fall into the collection box, and they need to be picked out and re-grinded, which is troublesome, time-consuming and labor-intensive, and easily reduces the efficiency of fine grinding of cosmetic production.

[0008] Furthermore, the friction between the screen and the inner wall of the device body is greater than the gravity of the screen, and the gravity of the screen itself and the gravity of the cosmetic raw materials thereon will not drive the screen to move downward.

[0009] Furthermore, the rotating gear has only half of the teeth, and the teeth on the rotating gear mesh with the teeth on the gear rod. When the rotating gear rotates and its teeth mesh with the teeth on the gear rod, the gear rod will be driven to move upward.
