AI Technical Summary

Technical Problem

Existing mask coating equipment has difficulty in achieving uniform coating of mask liquid during the rotation of the coating roller, resulting in uneven coating amount, affecting the consistency of mask quality, and it is impossible to achieve separate control of coating on both sides of the mask.

Method used

The guide shaft design allows the nonwoven fabric to change sides during winding and unwinding. Combined with the feeding nozzle controlled by the oscillating motor, the coating liquid is applied to both sides of the nonwoven fabric, and the excess liquid is recovered by the scraper, achieving uniform coating and recovery.

Benefits of technology

It improves the uniformity of mask liquid coating, reduces production costs, and enables independent control of double-sided mask coating, thereby improving the consistency of mask quality.

Abstract

The utility model discloses collagen mask liquid coating equipment, which relates to the technical field of mask liquid coating and comprises a conveyor body, a blanking device arranged at the top of the conveyor body, a mask liquid storage device fixedly mounted at the top of the conveyor body, and a recycling box placed at the bottom of the conveyor body. According to the collagen mask liquid coating equipment, the guide shaft is arranged, non-woven fabric is changed on the outer surface of the guide shaft, then the first discharging nozzle and the second discharging nozzle are used for coating the two faces of the non-woven fabric respectively, coating of the non-woven fabric is more uniform, the coating effect of mask liquid is improved, and the mask liquid can be uniformly coated through the scraper blade. According to the mask feeding device, redundant mask liquid is uniformly applied to the outer surface of the non-woven fabric, the mask liquid is recycled and collected through the shape of the scraper, the mask production cost is reduced, the first feeding nozzle and the second feeding nozzle swing left and right at the top of the non-woven fabric, mask liquid feeding is more uniform, and the mask quality is improved.
