AI Technical Summary

Technical Problem

Existing scraper coaters cannot precisely control the distance between the baffle plates when adjusting them, resulting in uneven blank widths on both sides of the substrate, affecting coating quality.

Method used

A driving mechanism is used to drive the two side plates to move toward each other, and the position of the baffle plate is accurately controlled by the screw rod and slider structure. The limiters and elastic parts are combined to ensure that the blank width on both sides of the substrate is equal, and the curved plate is used to avoid friction damage to the substrate.

Benefits of technology

It achieves precise control of the blank width on both sides of the substrate, ensures coating uniformity, simplifies the removal and cleaning process of the baffle plate, and improves production efficiency.

Abstract

The application discloses a coating machine and a use method thereof, and belongs to the technical field of coating machines. The coating machine comprises a machine base, a bottom roller and a scraper are installed on the machine base, and a material tank is installed on the machine base at a position on the side of the bottom roller. The material tank comprises a bottom plate and two side plates arranged on the bottom plate. The two side plates are symmetrically arranged with respect to a vertical plane in which a side center axis of the bottom roller is located. A driving mechanism for driving the two side plates to move towards each other is arranged on the bottom plate. Each of the two side plates comprises a material blocking plate and a positioning piece which are connected to each other. The driving mechanism stops when the side plate is driven to move to a position where the positioning piece contacts a side surface of a base material. The coating machine provided in the embodiment of the application is characterized in that the two side plates are symmetrically arranged with respect to the vertical plane in which the side center axis of the bottom roller is located, and the driving mechanism is arranged to drive the two side plates to move towards each other, so that the distance between the two side plates can be accurately controlled, and the white space widths on the two sides of the base material are ensured to be equal.
