Screen printing device

Abstract

The invention discloses a screen printing device. The screen printing device comprises a printing seat, a base and a supporting rod arranged on the top of the base, wherein the printing seat is movably arranged on the supporting rod through a movable block, an oil cavity is formed in the printing seat, a printing screen is arranged on the bottom of the oil cavity, a cavity cover is hinged to the top of the oil cavity, a scraper which is attached to the printing screen is arranged in the oil cavity, and the scraper is connected with a shifting piece which is arranged on the top of the printing seat. According to the screen printing device, the airtight oil cavity is adopted, an operator just needs to shift the shifting piece during operation, and oil paint is prevented from adhering to the operator; the printing screen is detachably connected with the printing seat, in this way, the printing screen can be replaced with printing screens with different patterns at any time, and adaptability is improved; meanwhile, the height of a silk screen base can be adjusted freely so that the requirements of different products can be met, and the screen printing device is simple in structure, convenient to use and economical.

Description

technical field [0001] The invention relates to a printing tool, in particular to a screen printing device. Background technique [0002] The technology of transferring the ink to the surface of paper, fabric, leather and other materials through plate-making, ink application, pressurization and other processes to reproduce the contents of the original manuscript in batches. Call it printing. There are many forms of printing: traditional offset printing, screen printing, digital printing, etc. Common printing methods can be divided into four categories: letterpress printing, gravure printing, offset printing and stencil printing: [0003] (1) Letterpress printing. The graphic part of the printing plate is raised, which is obviously higher than the blank part. The printing principle is similar to that of a seal. Early woodblock printing, movable type printing and later type printing all belong to letterpress printing. [0004] (2) Gravure printing, the graphic part of the p...

Problems solved by technology

[0007] In the production and processing of wooden toys, advanced printing tools are often used to print different patterns on the toy body, but the traditional printing equipment is too bulky and expensive, and is not suitable for small toy processing factories and small-batch toy processing. However, some existing manual printing devices will stick to the paint if the operator is not careful during the printing operation, and a single printing device can only print one pattern, so the applicability is not strong
