Problems solved by technology

Printing pressure is one of the five major variables in printing. Whether the pressure is constant or not is directly related to the consistency of printing. The general printing machine relies on the cylinder intake pressure or adopts pressure difference adjustment. The pressure adjustment is inconvenient, not intuitive, and easily affected The effect of air pressure instability
At the same time, due to the friction of the cylinder itself, the control accuracy and instantaneous response are not high
Therefore, it seems powerless for occasions with high requirements for printing film thickness control

Embodiment Construction

[0020] Such as figure 1 As shown, the scraper control mechanism of the screen printing machine includes a base 1, a scraper assembly, an ink flooding blade assembly, a scraper lifting mechanism and a scraper pressing mechanism. Such as figure 2 As shown, the left and right sides of base 1 respectively have an arm 36 protruding forward, the front portion of these two arms respectively has a scraper shaft hole 37, and the rear portion of these two arms respectively has a flooding knife shaft hole 38 . Such as figure 1 with image 3 As shown, the scraper assembly includes a scraper swing body 2 and a scraper 22 . The scraper is fixed on the front end of the scraper oscillating body. There is a scraper rotating shaft 31 at the rear of the scraper oscillating body. There are a roller 16 and a pressure rod 15 at the front of the left side. Such as Figure 5 As shown, the flood knife assembly includes a flood knife shaft 40 , a flood knife 32 and two side bars 41 . The shaft...

Abstract

The invention discloses a screen printing machine scraper control mechanism, which comprises a substrate (1), a scraper assembly, a covering ink blade assembly, a scraper lift mechanism and a scraper pressing mechanism. The scraper assembly comprises a scraper swing body (2) and a scraper (22); the covering ink blade assembly comprises a covering ink blade rotating shaft (40), a covering ink blade (32) and two side rods (41); the scraper lift mechanism comprises four-bar links (18, 19 and 21), a slide rail (17), a pull rod (12), an oscillating rod (8), a cam (7) and an electromagnetic brake motor (11); and the scraper pressing mechanism comprises a torsional spring (13), a worm wheel (6), a worm (5) and a pressure transmission seat (14). Two mechanisms are used for lifting motion of the scraper and pressure transmission, a worm and worm wheel mechanism drives the torsional spring for pressure adjustment, the pressure is convenient to adjust, the printing pressure stability is improved, the resistance of the lifting motion of the scraper cannot influence the printing pressure, and the mechanism controlled capacity is improved.

Description

technical field [0001] The invention relates to a component structure of a thick film printing machine and a scraper control mechanism of a screen printing machine. Background technique [0002] Thick film printing machine is a special equipment for printing circuits, graphics and resistors on electronic components by screen printing. Generally, the control of the screen printing squeegee relies on the cylinder to move straight up and down. Printing pressure is one of the five major variables in printing. Whether the pressure is constant or not is directly related to the consistency of printing. The general printing machine relies on the cylinder intake pressure or adopts pressure difference adjustment. The pressure adjustment is inconvenient, not intuitive, and easily affected The effect of air pressure instability. At the same time, due to the friction of the cylinder itself, the control accuracy and instantaneous response are not high. Therefore, it seems powerless for...
