Description

Technical Field

[0001] The utility model relates to the technical field of cosmetic processing, in particular to a grinding device for cosmetic processing and extraction. Background Art

[0002] Cosmetics are complex mixtures made from various raw materials that are rationally blended and processed. They can generally be divided into two categories: base raw materials and auxiliary raw materials. When processing powdered cosmetics, it is generally necessary to crush and grind the cosmetic raw materials.

[0003] Publication No. CN117299323A discloses a grinding device for cosmetic processing and extraction, wherein the coarse grinding shaft rotates to drive a plurality of blades to rotate, and the rotation of the plurality of blades can contact and cut the cosmetic raw materials, thereby preliminarily grinding the cosmetic raw materials, which is convenient for further grinding of the cosmetic raw materials in the future and improving the grinding efficiency of the cosmetic raw materials. The driving shaft rotates to drive the grinding core to rotate, and then the preliminarily ground cosmetic raw materials will fall into the inside of the grinding cylinder. The rotation of the grinding core will contact the preliminarily ground cosmetic raw materials, thereby quickly squeezing and crushing the preliminarily ground cosmetic raw materials, so that the cosmetic raw materials can be ground into powder, which is convenient for the subsequent processing and production of cosmetic powder. However, the patent still has the following problems in actual use:

[0004] The driving shaft rotates the grinding core, and the preliminarily ground cosmetic raw materials fall into the grinding barrel. The rotation of the grinding core contacts the preliminarily ground cosmetic raw materials, thereby quickly squeezing and crushing the preliminarily ground cosmetic raw materials. However, when grinding the cosmetic raw materials, the crushed cosmetic raw materials cannot be ground thoroughly, which causes the cosmetic raw materials that are not thoroughly ground to be mixed with the ground cosmetic raw materials. After the staff has ground the cosmetic raw materials, they need to pick out the cosmetic raw materials that are not ground well inside. This not only reduces the work efficiency of the staff, but also reduces the grinding quality of the cosmetic raw materials.

[0005] A grinding device for cosmetic processing and extraction is proposed to solve the above-mentioned problems. Utility Model Content
