Problems solved by technology

However, the opening area of ​​the traditional screen is too small. When these screens are directly used for parallel printing, the printing lines will also fall on the screen, and the uniformity of the ink will be affected by the blocking of the screen.
Some people in the market also adopt the method of parallel printing with large opening and low mesh number, but due to the lower mesh number of the screen, the stability of the screen tension is affected, which will cause serious deviations in the size of the printed graphics
In addition, in order to ensure that the printing lines can accurately fall into the large opening grid, it is necessary to apply machinery and equipment during the plate alignment, which does not meet the needs of lean production in terms of manpower, cost, and efficiency.

Embodiment Construction

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0022] See figure 2 , The embodiment of the present invention includes:

[0023] A knitting method of a mobile mesh structure screen includes the following steps:

[0024] (1) Before weaving the wire mesh, roughen the wire used for weaving the wire mesh to increase the surface roughness of the wire;

[0025] (2) When weaving, first evenly arrange the warp threads 2 in the longitudinal direction, and then arrange the weft threads 1 in the transverse direction, so that the weft threads 1 and the warp threads 2 are interwoven with ...

Abstract

A knitting method of a silk screen with a moved screen silk yarn structure is disclosed. The method includes (1) roughening silk yarn used for knitting the silk screen before silk screen knitting to increase roughness of the silk yarn, (2) moving weft silk yarn in two groups of third width zones to allow a first zone to only contain warp silk yarn arranged longitudinally, (3) arranging the silk yarn in the first zone, the first third zone, a second zone and the other third zone orderly and evenly at intervals, and (4) knitting in a circulating manner according to the silk yarn layout in the step (3) to form the silk screen. According to the silk screen knitted by the method, adhesive force of a sensitive emulsion on the silk screen is high, the sensitive emulsion is not liable to shed during a printing process, the service lifetime of a screen printing plate can be prolonged, ink permeating is made evener, and printing lines are more uniform in height, straighter, small in broadened width, low in ups and downs and good in printing effects.

Description

Technical field [0001] The invention relates to a knitting method of a moving mesh structure screen. Background technique [0002] Traditional wire mesh is a stainless steel wire with a smooth surface or a composite metal wire that is interlaced in the warp and weft directions. When weaving, the warp and weft are interlaced and evenly arranged to form a mesh structure with uniform openings, such as figure 1 As shown; after weaving the net yarn, it will be cut according to the requirements of different plate making angles. Generally, it will form an angle of 22.5 degrees, 30 degrees, and 45 degrees with the printed lines. After the screen is cut, it will undergo compound processing to form a compound screen with specific tension. After the composite screen is pre-treated and degreasing, it will be coated with photosensitive emulsion for the plate making process. Since the surface of the screen woven by this weaving method is very smooth, the photosensitive emulsion is often unabl...
