Coating machine is also called coating machine, scraper, automatic spraying machine, etc. Mainly used for liquid glue coating on textiles, cartons or leather surfaces of a mechanical equipment, the existing glue machine has many types, such as: drum glue machine, double-acting glue machine, double-station lifting glue machine. The coating machine sprays liquid such as glue or paint to the desired product by air pressure. The equipment adopts three-axis linkage, automatic operation, and is equipped with computer programming control path spraying. Mainly:
(1) Horizontal or double-acting glue applicator. Textiles are coated with a thin film through a slit between the glue knife and the work roll, and then the solvent is evaporated and the remaining glue layer is made by a platform heated by steam.
(2) Drum glue coating machine. There is a hollow metal drum heated by steam instead of a drying table.
(3) Vertical or inclined dippers. After the textiles are dipped in the mortar, the excessive amount of the mortar on the surface is scraped off by the knife and the compacting roller. Then the solvent is volatilized by the vertical or inclined drying table and the remaining adhesive layer is left.
(4) Desktop glue machine sprays glue or paint onto materials by air pressure. The equipment adopts three-axis linkage, automatic operation, and is equipped with computer programming control path spraying. Spraying thickness and time can be set, simple and easy to operate.
