AI Technical Summary
During the production of plasters, air can easily get mixed in when the plaster is spread, resulting in poor quantitative effect. In addition, the plaster is prone to collapse and spread, which affects the subsequent film coating, extrusion and shaping.
A plaster spreading device was designed. The device uses an electric guide rail to drive the fixed material outer cylinder to fit and seal with the coating. The position of the quantitative sealing scraper is adjusted by a moving part. The air in the plaster is discharged with the help of a waterproof and breathable membrane. The plaster is cooled and shaped by an exhaust head and an air blowing head to ensure the quantitative distribution of the plaster and prevent collapse.
It achieves precise quantitative application and rapid cooling and molding of the ointment, preventing the ointment from collapsing and ensuring the shaping effect of the subsequent film coating.
