Simple double-sided dip-coating metering device

Abstract

The invention discloses a simple double-sided dip-coating metering device which is used for solving the defects that a coating layer in the prior art is difficult to realize precise metering control, complex in structure, inconvenient in metering adjustment, and the like. According to the technical scheme, the key point is that the simple double-sided dip-coating metering device consists of a rack as well as a dip-coating slot, a dip-coating slot guide roller and a coating metering unit which are mounted on the rack, wherein the coating metering unit is arranged above the dip-coating slot; and after being output from the dip-coating slot guide roller, a base material is perpendicularly conveyed to pass through the coating metering unit and perpendicularly pass through a double-sided dryer. The simple double-sided dip-coating metering device is characterized in that the coating metering unit is composed of a metering roller which is matched on one surface of the base material and an air knife which is matched on the other surface of the base material; the metering roller is a power-driven drive roller; the metering roller and one surface of the base material are in linear contact; and an air outlet of the air knife is positioned in the outer side of the other surface of the base material, and is opposite to a position, corresponding to a contact line of the metering roller, of the base material.

Description

technical field [0001] The invention relates to a double-sided coating mechanism for roll substrates, in particular to a simple double-sided dip-coating metering device. Background technique [0002] The commonly used double-sided dip coating device for roll substrates is like Chinese patent application No. 2013101634 [0003] A substrate dip coating automatic feeding device disclosed in No. 21.1 is composed of a frame, a supporting roller installed on the frame, a dip coating tank, a dip coating tank guide roller, and a scraper mechanism. The dip coating tank guide roller is located on In the dip-coating tank, the supporting roller is set on one side above the dip-coating tank, and the scraping mechanism is set on the other side above the dip-coating tank. The scraping mechanism is composed of a pair of scraping rollers arranged vertically up and down. From the groove guide roller to the scraping mechanism, it is inclined transmission, and after passing through the scrapin...
