Film thickness control of flat pasting machine
Easy control of the film thickness of the flat pasting machine is a major advantage of the roll coating method. In addition to the above-mentioned adjustment of the coating viscosity to control the thickness, it can also be realized by adjusting the rotation speed of the paint roller or the distance between the paint roller and the coated object.
For the same direction roller coating method, the paint roller has fast speed, thin film, slow speed and thick film. If the distance between the paint roller and the coated object is large, the film is thick, otherwise it is thin. For the reverse roller coating method, the adjustment is slightly more complex. The pressure and speed ratio between the feeding roller and the painting roller will affect the film thickness.
Design of roller coater
Solvent resistant rubber roller and stepless adjustment transmission are adopted. The conveyor belt, Pu rubber wheel and metering light wheel are independent motor frequency conversion speed regulation, which makes the processing more accurate.
Roller coater effect
The surface of the paint film treated by the roller coater is smooth, with good plumpness, no stacking of paint before and after, which can be the same as the spraying effect, but the paint thickness is greatly reduced.
Characteristics of roller coater
It can improve production efficiency, reduce coating consumption, improve product quality and meet the requirements of electronic assembly processes such as wave soldering. The utility model has the advantages of uniform coating thickness and convenient adjustment.
