The squeegee is mounted on the tool holder by a support spacer, and the support shims can increase the elasticity of the squeegee, and the thickness thereof is 0.25 to 0.35 mm. The installation position, angle and extension length of the squeegee have an important influence on printing, so the technicians are required to have certain requirements. 1, the installation location The use of volatile ink in gravure printing, the shorter the arc between the contact point of the squeegee and the printing plate and the embossing point, the smaller the viscosity change of the ink, the more favorable the transfer of the ink, the better the quality of the printed product. Usually, the distance between the contact point of the doctor blade and the printing plate and the embossing point is about 1/4 of the diameter of the plate cylinder. 2, the installation angle The indirect assembly and the reverse mounting respectively form an ink accumulation zone, and the ink deposition zone formed by the forward mounting has a tendency to push outward toward the doctor blade, and the ink deposition zone formed by the reverse mounting is directed to the offset printing blade. The trend, in contrast, the reverse installation of the scraping effect is good. When the printing pressure is constant, whether the ink transfer in the ink in the plate cylinder is good or not is directly determined by the viscosity, so the gravure printing is mainly used in the forward direction, and the contact angle is generally 70°. 3, extended length Different printing requirements, the thickness of the squeegee is different, resulting in different extension lengths during installation; the same thickness of the squeegee is also lengthy when installed. Generally, the squeegee has an extension length of 25 mm, and the extension length of the support shims is preferably 12.5 mm. The length of the squeegee extension is different, and the degree of bending during squeegee is also different, forming a hard squeegee and a soft squeegee, which are related to the thickness and the extension length of the squeegee. The effect of scraping ink during hard scraping is not good, the wear of the doctor blade and the plate cylinder is serious, and the service life is shortened; the soft scraping can prolong the service life and easily generate fog. Therefore, the length of the extension should be strictly controlled. Article source address: http:// Our Aluminum Fence product line is fabricated from 6063 series
