Roll coating is a coating technology to get a coating on the surface of a roller with a coating. The utility model is characterized in that can adjust the film thickness; can make large area painting. In the construction can be continuous; high solids, high viscosity, small amount of solvent, less pollution; the production efficiency is high, compared with the brush effect improved by about 2 times, good coating quality, uniform, no brush marks, sagging etc. the flaw, but need to repair the corner. The tools are flexible and easy to operate, and different decorative rollers can be made with different rollers.
The main tool is the work roller roller brush, in accordance with the structure can be divided into European, American and Swedish three categories, European style is used in-line rolling brush rack, the drum has a lock core, a lock core in the process of using tight rolling brush rack beams, to hold core as the center of the rolling drum, swaying roller the axial and radial direction is radial and axial size of roller is contained in the core holding space and the difference of the lock core. The European roller drum is generally made of sticky and sewn technology. Due to the rise of hot melt technology, the structure of Mei changed Europe is used to install straight through roller brush, but the principle has not changed.
American rolling brush rack straight brush head for installation, the biggest characteristics of American structure is the presence of CAGE, cage by the positive cap, a cap and a back cap is connected with the ribs, generally 4-5 tendons, rolling brush rack head set screw system, rear dot, cage structure is fixed on the rolling brush rack the beam, the axial direction is decided by the difference of nut and the size and the formation of cage dot mounting size, aperture is determined by radial swaying back cap and rolling brush frame beam diameter difference. The elastic press of the ribs of the American style roller compacts the inner wall of the head.
Swedish and American rolling brush rack rolling brush rack are used for straight brush head mounted to American canceled rib structure, moving in the rolling brush rack rear limit back cap is packed, cap on both sides of the RBI, to control the amount of axial shaking drum, radial sway control method of momentum and American the same. The Swedish roller brushing rack presses the inner wall of the head with the elastic pressure of the cap.
All of the three kinds of roller brushes can be used repeatedly to save the environment. OK, after installing the rolling brush head, the center of gravity should be located on the center line of the handle and perpendicular to the cross beam of the rolling brush rack, so that the fatigue degree of rolling brush operation can be reduced. All plastic parts should be made of raw material and have enough strength to avoid breaking in the process of transportation and rolling.
