AI Technical Summary

Technical Problem

Cosmetic bottle caps are exposed during the spraying process, making them prone to dust or foreign matter accumulation, resulting in noticeable defects that affect appearance and feel, reduce wear resistance and corrosion resistance, and decrease practicality.

Method used

Design a dust blocking assembly including a base plate, a housing, a motor, gears, a rack, a torsion spring, and a magnet. The motor drives the gears to slide the rack, and the magnet attracts the bottle cap, sealing the opening of the housing to prevent dust from entering. Combined with a heating plate to dry the paint, it achieves dust prevention and curing.

Benefits of technology

It effectively blocks dust and impurities in the air, ensures uniform paint spraying, enhances aesthetics and practicality, avoids paint defects, and improves wear resistance and corrosion resistance.

Abstract

This utility model relates to the field of cosmetic bottle cap spraying technology. The component is a dust-blocking assembly used during cosmetic bottle cap spraying, comprising a base plate and a housing. The upper end of the outer wall of the base plate is fixedly connected to the housing. Dust-proof structures for cosmetic bottle caps are provided on the front and rear sides of the housing. A sliding rod is fixedly connected to the left side of the inner wall of the housing. This dust-blocking assembly for cosmetic bottle cap spraying utilizes the dust-proof structure. A rack slides outward, driving the plate and magnetic block to move outward synchronously. A motor ultimately drives the plate and magnetic block to move, feeding and discharging cosmetic bottle caps, making the operation more convenient. Simultaneously, a movable vertical plate seals the opening on the right side of the housing, blocking a large amount of airborne dust and impurities, thus achieving a dust-proof effect. This allows the paint on the cosmetic bottle caps to cure more smoothly, improving aesthetics and preventing damage to the paint surface, thereby enhancing practicality.
