Referring again to Fig. 6, when screen painting, scrape printing cutter 200 scrapes the printing material 300 on grenadine 110 back and forth on printing screen plate with single fixed-direction after, scrape printing cutter 200 has downward strength and pushed grenadine 110 in order to by printing material 300, arrives the printed material (not shown) for printing again by grenadine 110 after the printing rete 130 (macromolecule membranous layer or metallic diaphragm) on grenadine 110 surface.
Pressure that scrape printing cutter 200 presses down and deformation quantity is subject at grenadine 110 (warp thread or weft yarn), especially in the region that scrape printing cutter 200 both sides downforce is larger, but rely on setting other tension force each in arbitrary region on grenadine 110, different tension force is presented in the surperficial zones of different of grenadine 110 of half tone 100, this anisotropic specific tensile region, different from adjacent region tension force, the coining release forming local avoids squeegee pressure in given zone excessive, reduce deformation or the displacement of grenadine 110 or printing rete 130, the printing life-span is longer.And in specific region and adjacent region produces certain Tension Difference, therefore the coining that when scrape printing cutter 200 presses down, grenadine 110 and printing rete 130 form local discharges, make stressed printing rete 130 lines and figure not have the situation of dimension enlargement and displacement, reach more accurate printing effect.Printing material also can not extend out because of print film, reaches good closure, and printing material 300 can be saved, and then reaches the object of accurate printing width, also can promote printing closure make printing lines or Graph Control more accurate.
Illustrate: solar energy silicon crystal chip printing screen plate, half tone tension force is iso uniform values, its printed pattern is the printing of unidirectional multi-line, scrape printing cutter direction of advance and printing line orientations consistent (parallel or vertical), when scrape printing cutter presses down, because of the relation that scrape printing cutter distance webs frame Edge Distance is less, under the state that the arbitrary region of traditional grenadine all presents conforming tension force, scrape printing cutter both sides tension force is comparatively large, makes the outside displacement of printing rete cause expansion line and life-span to reduce.
But by means of the screen structure of this case, zones of different presents different tension force on half tone, and be different from tropism's tension force such as the uniformity that tradition throws the net.In scrape printing cutter direction of advance and printing line orientations consistent (parallel or vertical), because of relation that scrape printing cutter distance webs frame Edge Distance is less when scrape printing cutter presses down, this anisotropic specific tensile region, different from adjacent region tension force, the coining release forming local avoids squeegee pressure in given zone excessive, reduce deformation and the wearing and tearing of grenadine or printing rete, to extend the half tone life-span, also avoid printing rete because of the excessive deformation uneven when scraping or displacement, so reach the object of accurately printing make printing lines or Graph Control more accurate.
More than illustrate just illustrative for the purpose of the present invention; and nonrestrictive, those of ordinary skill in the art understand, when not departing from the spirit and scope that claim limits; many amendments, change or equivalence can be made, but all will fall within protection scope of the present invention.
