Description

[Detailed description of the invention] The present invention relates to a flat screen pattern matching device, and more specifically, a flat screen pattern matching device for automatic screen printing machines that does not cause deformation of the flat screen frame and allows easy and accurate pattern matching. This invention relates to a type matching device for tsutoscreen.

The flat screen pattern matching device in automatic screen printing machines is one of the important devices for ensuring the precision of printing pattern matching, and various types and structures have been used in practical use. , all of them were of the type in which the shape adjustment was performed directly on the flat screen frame.

However, since most screen frames for flat screens are made of aluminum alloy to reduce weight, they lack strength and rigidity and are easily deformed by slight external forces. Therefore, in conventional mold matching equipment, the screen frame is deformed during mold matching, and at the same time, the screen pattern that is engraved with tension and photo-engraved on this frame is also distorted due to the deformation, making it difficult to achieve partial accuracy. It is often impossible to match the molds.

For this reason, in printing work, in order to ensure accurate pattern matching over the entire area of the design, it is necessary to ensure that the pattern is exactly the same as when it was photo-engraved, without causing any deformation.
It is necessary to be able to set it on the textile printing machine, and to be able to adjust the pattern matching while maintaining this setting.

When adjusting the screen frame directly as in the conventional method, it only has the adjustment function, so if you focus on pattern matching, the screen frame will deform, and if you prevent the deformation, pattern matching will be impossible. This makes it difficult to accurately match the pattern over the entire area.

That is, the purpose of the present invention is to eliminate the above-mentioned drawbacks,
To provide a flat screen pattern matching device capable of easily and accurately matching patterns without causing deformation of the flat screen.

Another object of the present invention is to provide a type matching device having a structure in which the type matching of flat screens is performed by adjusting the frame on which the screen frame is set and supported, without directly adjusting the screen frame. .
