The Working Principle and Function of the Coating Machine

The coating machine is mainly used for the surface treatment of some films or paper, which can be used for coating production, changing its state, adding different types of functions, and so on. Indeed, such a coating machine has a wide range of applications. However, I believe that even the staff who have learned the operation may not know what the coating machine is for and what is the working principle?

Litong are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.

1. The working principle of the coating machine

The working principle of the wood coating machine and glass coating machine is to coat the rolled substrate (such as paper, cloth, leather, aluminum foil, plastic film) with a layer of glue, paint or ink with a specific function, and then rewind it after drying. It adopts a special high-speed coating head, which can effectively reduce the generation of air bubbles. Rewinding and unwinding are equipped with full-speed automatic film splicing mechanism, double-station or single-station, tension closed-loop automatic control and other devices. The coating machine adopts a special multi-functional coating head, which can realize various forms of surface coating. The rewinding and unwinding of the coating machine are equipped with full-speed automatic film splicing mechanism and PLC program tension closed-loop automatic control.

Coating machines are mainly used in some shoe material production and electronic industries, and many coating machines can process EVA and PE materials. In this way, the brushing treatment of the surface can be completed quickly, and its working performance can be effectively improved to ensure the processing quality. Therefore, many manufacturers also have large quantities of different types of coating machines.

Because the coating machine needs to apply ink or glue type substances evenly to aluminum foil, plastic and other films, the process requirements of the equipment are also very high, and it must reach a high technical level to complete the operation. Moreover, such curtain coating machine must operate at high speed without interruption, which is also conducive to improving the overall work efficiency. Therefore, before we buy equipment, we must also do a good job of understanding its performance. The coating machine is suitable for the coating of shoe materials, electronic industry, BOPP sealing tape, sponge, EVA, PE, PET, cloth, etc.

In fact, the working principle of the coating machine is basically the same. Even if the type is different, the operation mode and processing mode will not be very different. Now many businesses are using automatic coating machines, so the operation is simpler. When purchasing equipment, we must also take into account our actual needs and the quality of products supplied by manufacturers. It is better to buy equipment with high cost performance.

Tablet coating machines apply a thin outer layer or coating to tablet dosage forms. There are three main types: standard coating pans, perforated coating pans, and fluidized bed or air suspension coaters. Standard coating pans apply coatings through spraying into a rotating tablet bed. Perforated coating pans have perforations that improve drying efficiency. Fluidized bed coaters suspend tablets in warm air to coat them from below and allow for continuous processing. All coating machine types aim to uniformly and efficiently apply thin coatings to improve properties like taste, stability, or identification.
