Scraping knife regulating device

Abstract

The invention discloses a scraping knife regulating device. The scraping knife regulating device comprises a lifting regulating mechanism, an angle regulating mechanism and a scraping knife fixing base, wherein the scraping knife fixing base is provided with a through hole and a rotary shaft which penetrates through the through hole and is used for fixing the lifting regulating mechanism to the scraping knife fixing base; a rotary hole for the rotary shaft to penetrate through is formed in the bottom of the lifting regulating mechanism; and the lifting regulating mechanism can be used for controlling a scraping knife rotation angle by rotating around the rotary shaft under the action of the angle regulating mechanism. According to the scraping knife regulating device provided by the invention, the lifting regulating mechanism, the angle regulating mechanism and the scraping knife fixing base are integrated through the rotary shaft; and compared with the scraping knife regulating device provided with the lifting regulating mechanism and the angle regulating mechanism which are separated from each other, the scraping knife regulating device provided by the invention is simpler, more compact and more reasonable in structure and smaller in occupied space.

Description

technical field [0001] The invention relates to a scraper adjusting device, which is used for scraping paint on a cylinder in gravure printing, and belongs to the technical field of scraper adjustment. Background technique [0002] A gravure printing machine is an important method for forming a color layer on a steel plate. A conventional gravure printing machine mainly includes feeding equipment for providing coatings; a suction roller whose circumferential surface is connected with the feeding equipment, so The peripheral surface has a plurality of depressions that form image areas when filled with the paint; a rubber coating roller, whose peripheral surface is connected with the suction roller, is used to accept the coating to form on the coating roller. image area, and transfer the image area to the steel plate. During printing, a part of the paint enters the depression on the suction roller for forming the image area, and a part is located outside the depression on the...

Problems solved by technology

[0005] In the above scraper mechanism with various adjustment functions, the scraper is respectively fixed with the lifting adjustment mechanism and the inclination adjustment mechanism. When adjusting the height adjustment mechanism, any part of the angle adjustment mechanism will not work. Any part of the adjustment mechanism does not work, which makes the angle adjustment mechanism and the height adjustment mechanism become two separate adjustment systems, resulting in a large structure of the scraper mechanism and a large space occupation

In addition, a hole is set on the frame of the scraper mechanism, and the connecting guide rod and the shaft rod pass through the hole. In this mechanism, the shaft rod only plays a fixed role, and has no effect on the angle adjustment and height adjustment of the scraper. Therefore, in order to achieve angle adjustment, it is necessary to set up a rotating shaft separately, thereby further increasing the volume of the scraper mechanism and further increasing the occupied space of the scraper
