Application of Coating Roller
1、 Definition of coating roller
The coating roller is the core component of the coating machine. The main function of the coating roller in the coating machine is to evenly cover materials such as coatings on thin films, paper, and printed materials, achieving aesthetic and anti-corrosion effects. The structure of the coating roller is usually composed of the roller body, bearings, etc., and the surface can be chrome plated, coated, etc. according to the requirements. The following are the main functions of the coating roller.
2、 The function of the coating roller
1. Uniform coating
By using appropriate rotational speed and pressure, the coating roller can evenly cover the surface of the roller body and achieve uniform coating of the film and paper when the coating passes through it. Transfer it to the surface of the object that needs to be coated, in order to achieve uniform coating on the surface of the object.

2. Make the surface flat
The texture or groove on the surface of the coating roller can control the thickness and uniformity of the coating material. By squeezing, the coating roller can remove excess paint from the surface of the item, thus better controlling the uniformity of the paint and making the product surface smooth.
3. Save paint
Due to the consistent pressure of the coating roller on the surface of the product, the coating can be more evenly distributed, achieving the effect of saving coating costs.
4. Transfer coating materials
The transmission device in the coating machine is connected to the coating roller, and under the combined action of the driving device and the rotation of the coating roller, the coating material and product can be smoothly transmitted.
In summary, the role of the coating roller in the coating process is very important. The coating roller achieves the coating of the product through transmission and extrusion, improving the surface aesthetics and smoothness of the product.
