The specific embodiment
Below in conjunction with drawings and Examples, the utility model will be further described.
As shown in figures 1 and 3, the utility model discloses a kind of serigraphy head, comprise that horizontal mobile device 1, the first scraper 61, the first return blade 63, the second scraper 62 and the second return blade 64(are referring to Fig. 2 and Fig. 4); The first scraper 61, the first return blade 63, the second scraper 62 and the second return blade 64 are all installed on horizontal mobile device 1 by telescopic clamp 2; Described telescopic clamp 2 is connected with drive unit (not shown).Telescopic clamp 2 elongates or shortens under the driving of drive unit, whether contacts with half tone 3 to control the scraper/return blade being arranged in telescopic clamp 2.
As shown in Figure 2 and Figure 4, telescopic clamp 2 on horizontal mobile device 1 sets gradually the second scraper 62, the second return blade 64, the first return blade 63 and the first scraper 61 by the initial movable direction of horizontal mobile device 1, arrange according to this order, guaranteeing has corresponding return blade to carry out feed back to slurry after scraper scrapes.
The telescopic clamp 2 that the first scraper 61 is installed is all connected with the first drive unit with the telescopic clamp 2 that the first return blade 63 is installed, thereby guarantees that the tip of the first scraper 61 is consistent to the distance of half tone 3 to the distance of half tone 3 and the tip of the first return blade 63; The telescopic clamp 2 that the second scraper 62 is installed is all connected with the second drive unit with the telescopic clamp 2 that the second return blade 64 is installed, thereby guarantees that the tip of the second scraper 62 is consistent to the distance of half tone 3 to the distance of half tone 3 and the tip of the second return blade 64; Under the effect of the first drive unit and the second drive unit, the first scraper 61 contacts with half tone 3 when different with the second scraper 62, thus assurance the first scraper 61/ second scraper 62 scrape printing effect.
Because the main grid line on cell panel is less demanding for the fineness of printing, thereby the second scraper is different from the structure of the first scraper (referring to Fig. 6).As shown in Figure 5, the second scraper 62 is provided with three sections of blades that are arranged side by side, and the interstitial site between two sections of adjacent blades and width all mate with the main grid line on half tone 3 to be printed; Meeting main grid line does not need the demand of secondary printing.In like manner, the breach mating with the main grid line width on half tone 3 to be printed also can be set on the blade of the second scraper 62.
When work, stock 4(cell piece to be printed) be placed on ink pad 5, printing screen plate 3 is covered in stock 4 surfaces, horizontal mobile device 1 drive scraper and return blade according to original position---steering position---original position moves reciprocatingly.
