Background technique

Lipstick is one of the essential beauty cosmetics for women. With the improvement of people's living standards, consumers are pursuing higher and higher quality of life, and the market demand for lipstick is gradually increasing. Major cosmetics companies urgently need to improve the production efficiency of lipstick. and increase production capacity. The results of market research show that at present, in the domestic cosmetics industry, the assembly process of lipstick products is still dominated by manual assembly on the assembly line, with relatively low quality and productivity, and only medium and low-end lipstick products can be produced. In order to improve the competitiveness of the market, some domestic enterprises have begun to introduce advanced assembly technology. Through digestion and absorption, they have realized the automation of some assembly processes.

The driven pulley is fixed on the pulley shaft through the bearing retaining ring A and the key, so that the driven pulley can transmit the torque of the rotating motor of the screw motion mechanism to the screwed connection shaft. The axial limit ring is fixed on the screw-fit connecting shaft in the axial direction, and prevents the screw-fit connecting shaft from falling along the axial direction, and the pneumatic joint is used as an intermediate connecting part between the screw-fit connecting shaft and the pneumatic joint.

The vacuum suction cup is coaxially installed on the spin-fit connection shaft. In order to lead the vacuum formed by the vacuum suction cup to the vacuum suction cup, an internal ventilation hole is designed on the spin-fit connection shaft.
