Working principle and characteristics of coating machine

Working principle and characteristics of coating machine: The coating machine is used for the coating production of BOPP sealing adhesive tape. Rolls of substrate are coated with a layer of adhesive, paint, or ink for a specific function, etc., and dried before rewinding. It adopts a special high-speed coating head, which can effectively reduce the generation of bubbles, and the rewinding and unwinding of the coating machine is equipped with a full-speed automatic film splicing mechanism, and the tension is automatically controlled in a closed-loop manner.

The workflow of the coating machine: the substrate of the roll, such as paper, cloth, leather, aluminum foil, plastic film, etc., is coated with a layer of glue, paint or ink with specific functions, and dried and rewinded.

It is suitable for the production of soft substrates such as PVC/PE film Simply put, it is to apply glue to the film. These include gluing, drying, winding and tension control. The film can be PVC, PE, PET... It can also be some paper.

In order to meet the packaging requirements of cargo container storage, transportation and mechanized loading and unloading operations, we have designed and manufactured a series of products such as tray coating machine, top type anti-tension coating machine and pre-tension automatic film coating machine, which are widely used in foreign trade exports, food and beverage, making and irrigation, papermaking, dyes, plastic chemicals, glass ceramics, mechanical and electrical castings and other products, improving production efficiency, and preventing damage to goods in the handling process, and playing a dust-proof, moisture-proof and cleaning role.

(1) Features and functions of the combined scraper coating head:

Scraper coating is routinely controlled and operated by adjusting the angle of the scraper. But the combined scraper complements without changing the angle of the scraper. Only the characteristics of changing the blade pressurized load to control the coating amount.

This helps to prevent squeegee streaks or coating quality issues when changing the coating volume. This is especially important when coating at low weights. In order to change the pressure load at the tip of the scraper, the clamping beam equipped with the scraper is moved in or out on the rail. However, the position of the scraper pressurized bracket is not changed.
