Description

Technical Field

[0001] The utility model relates to the technical field of dressing production, in particular to a liquid raw material mixer for dressing production. Background Art

[0002] Dressing is a category of skin care products, which is used to hydrate the skin. It also has multiple functions such as moisturizing, nourishing, nourishing, improving appearance, and deep cleaning. There are many benefits of dressing, such as moisturizing, whitening, cleaning, and assisting in repairing damaged skin. There are many types of dressings, and different types of dressings have different functions. The most common dressing is moisturizing dressing, which provides a closed environment for the face after being applied to the face, so that the water content of the stratum corneum increases. Cleansing dressing, the main function of this dressing is to remove the oil on the face, and some of them also accelerate the metabolism of the face and exfoliate the skin. Although dressing has certain benefits, applying dressing every day is also harmful to the skin, and it is easy to cause pores to be clogged and acne to appear. This is because frequent dressing makes the skin bear and cannot absorb the nutrients in the dressing, resulting in excess nutrients, which eventually leads to acne.

[0003] However, in the production process, the existing dressings are generally composed of dressing paper and dressing liquid, and the dressing liquid is made by mixing liquid raw materials and powdered additives. The existing mixing tank generally adopts natural dissolution in the mixing process, and the dilution and dissolution time of the materials is relatively long. In addition, the internal powdered additives are easy to precipitate and accumulate at the bottom of the tank body, affecting the mixing rate and reducing work efficiency. At the same time, after the dressing liquid is made, since the liquid has a certain viscosity, the inner wall of the bottom of the tank body is easy to adhere and stick to residues. After a period of time, it may cause deterioration, affecting the quality of the dressing liquid when the materials are mixed next time, which is inconvenient for staff to use. In addition, the mixer is generally heavy, and a lot of manpower and material resources are required during the indoor movement, which wastes human resources and is inconvenient for staff to carry.
