Auxiliary fixture for silk-screen printing and working method

Abstract

The invention relates to an auxiliary fixture for silk-screen printing and a working method. The auxiliary fixture comprises a base plate, a support rod, a middle placing device, return springs, two bonding devices and two stop frames; the middle part of the base plate is connected with the middle placing device through the support rod; the left and right ends of the middle placing device are connected with the two bonding devices through the return springs; the bonding devices are connected with the base plate through a sliding fit mode; and the two stop frames are arranged at the left and right ends of the base plate. The auxiliary fixture can solve such difficulties as difficult positioning of printing objects before silk-screen printing of textures due to softer texture materials, failed pattern printing caused by possible corrugation or deviation condition of the textures during printing and easy influence on the quality of the textures due to the ink dispersion phenomenon causedby delayed drying of ink after printing on surfaces due to higher permeability of the textures.

Description

technical field [0001] The invention relates to the field of screen printing, in particular to an auxiliary fixture for screen printing and a working method. Background technique [0002] Screen printing belongs to stencil printing. Screen printing is composed of five major elements, namely, screen printing plate, squeegee, ink, printing table and substrate. The basic principle of screen printing is to use the mesh part of the screen printing plate to Printing is based on the basic principle that the ink is transparent, and the non-graphic part of the mesh is impervious to ink. As a printing with a wide range of applications, screen printing can be used to print fabrics. However, the following problems may occur when printing fabrics : [0003] 1. The printing object needs to be positioned before screen printing, but the fabric material is relatively soft and difficult to locate, and the fabric may be wrinkled or shifted during printing, resulting in the failure to print th...

AI Technical Summary

Problems solved by technology

[0006] The invention can solve the problem of positioning the printing object before fabric screen printing, but the fabric material is relatively soft and difficult to locate, and the fabric may be wrinkled or shifted during printing, resulting in the failure of the pattern to be printed. The fabric has strong penetrability. After the ink is printed on the surface, it often cannot be dried in time, which will cause the ink to melt and easily affect the quality of the fabric.
