Novel screen drawing machine

Abstract

The invention discloses a novel screen drawing machine which comprises a screen drawing machine body and a hydraulic lifting table installed at the center position of the screen drawing machine body. The screen drawing machine body is provided with a supporting frame, blowers, a timing device, a pressing block and a wheel. Operation tables are arranged on the front face of the supporting frame. The operation tables are connected with the supporting frame. The blowers are installed on the back face of the supporting frame. The pressing block is a rectangular cast iron block with a flat surface. The wheel comprises a cylinder rotating shaft and supporting rods installed at the two ends of the rotating shaft. The wheel is movably installed on the supporting frame through the supporting rods. The timing device is installed on the side face of the supporting frame. A platform is arranged at the upper end of the hydraulic lifting table. The platform is provided with tempered glass, and length scales are arranged on the edge of the tempered glass. According to the novel screen drawing machine, the cost is reduced by 30%, and meanwhile superiority of materials in a printing area is ensured.

Description

technical field [0001] The invention belongs to the technical field of plate-making equipment, in particular to a novel net-drawing machine. Background technique [0002] Transcript printing is the simplest form of stencil printing, which began at the end of the 19th century. This kind of printing is on special stencil paper, through typewriter or stylus to make stencil graphic plate, and printing on the stencil plate with ink roller, the ideal printing effect can be obtained on the substrate. In stencil printing, the most widely used is screen printing. Screen printing is to stretch silk fabrics, synthetic fabrics or metal screens on the screen frame, and use manual engraving of paint films or photochemical plate-making methods to make screen printing plates. . Modern screen printing technology is to use photosensitive materials to make screen printing plates by means of photographic plate making (so that the screen holes of the graphic part on the screen printing plate a...

AI Technical Summary

Problems solved by technology

The principle of stencil printing is: when the printing plate (the hole that can pass the ink is made on the base of the paper film plate or other plates), when printing, the ink is transferred to the substrate (paper, ceramics, etc.) through the holes of the stencil through a certain pressure. ) to form images or characters. During the manufacturing process of the screen plate, a stretching machine is needed to stretch the net. When manufacturing a composite net, the existing stretching machine wastes materials seriously. Some of the materials are expensive, and it is a pity to waste them. There is a need for a stretching machine that saves raw materials
