Abstract
The utility model provides a screen printing plate protecting structure which comprises a screen cloth. The screen cloth is provided with a printing area, a scraper face and an attaching-printing face. The printing area of the screen cloth is attached to an object to be printed through the attaching-printing face, so that a pattern in the printing area is printed to the object to be printed. The screen printing plate protecting structure is characterized in that the screen cloth further comprises at least one protecting layer which is arranged on the scraper face and placed on the periphery of the printing area. According to the screen printing plate protecting structure, the phenomenon of screen cloth breakage can be reduced, and therefore the production efficiency is improved.
Description
Technical field
The utility model is about a kind of screen structure, especially in regard to a kind of half tone protection structure that can prevent screen cloth breakage when printing.
Background technology
Screen cloth is the important tool of screen painting, also can be described as the important foundation of screen painting, and it is mainly formed with warp, latitude direction interlacing by the screen cloth of the how imperial fiber of spy, nylon fiber or metal material, after opening, is fixed on a screen frame by certain tension force.The function of screen cloth except be form version line, the China ink amount seeing through in the time of also can controlling screen painting; Therefore, screen cloth for the precision of printing, print black thickness and print black infiltration capacity and all can produce very large impact.
The print principle of screen painting, utilize the opening forming after interweaving through, parallel of the chemical reaction of emulsion to ultraviolet and half tone to carry out photosensitive lithographic, make the part of non-plating be subject to photo-hardening and block mesh, plating part, because of not after chemical reaction of emulsion, can be dissolved and hollow out when meeting water.While carrying out screen painting, operator can utilize scraper to exert pressure and then scrape Yin Mo, makes to print China ink and on printed material, stamps pattern by the mesh of hollow out, to reach the object of printing.
What Fig. 1 was shown is the stereogram of screen cloth of the prior art.As shown in Figure 1, half tone of the prior art comprises a Printing Zone A and a non-Printing Zone B.When half tone of the prior art is when printing, be that Printing Zone is positioned on thing to be printed, and because thing to be printed has certain thickness relation, between screen cloth and printing table, can form the drop of a height distance.When printing, the non-Printing Zone B that the moving direction of scraper encloses from beyond the region of objective existence to be printed moves toward the Printing Zone A of thing to be printed top, and therefore, the screen cloth that the downward applied pressure of scraper can first make beyond the region of objective existence to be printed enclose presses to printing table.When scraper is passed through the intersection of non-Printing Zone and Printing Zone, the high low head between screen cloth and printing table can make the acute angle of thing to be printed cause the wearing and tearing of screen cloth.In addition, the friction between scraper and half tone also can cause the wearing and tearing of screen cloth.For these reasons, under long-term use, can cause the harmful effects such as screen cloth breakage or ink leak, not only affect the service life of screen cloth, more increase the cost of operation.
utility model content
For the foregoing reasons, the purpose of this utility model is to provide a kind of half tone protection structure, and it can pass through the setting of a protective layer, reaches the object that prevents screen cloth breakage when printing.
For reaching aforementioned object, the utility model provides a kind of half tone protection structure, comprises a screen cloth, and it has a Printing Zone, a blade face and is pasted seal face.Fit with a thing to be printed by pasting seal face in the Printing Zone of screen cloth, with by the pattern printing on this Printing Zone to this thing to be printed.Wherein, half tone protection structure is characterised in that: described screen cloth further comprises at least one protective layer, and it is arranged in described blade face and is positioned at periphery, Printing Zone.
According to an embodiment of the present utility model, the thickness of at least one protective layer adds that the thickness of screen cloth equals the thickness of thing to be printed.
According to an embodiment of the present utility model, protective layer can by a diaphragm, an emulsion layer or having a flexible polymer composite be formed.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view that shows screen cloth of the prior art;
Fig. 2 is the side cutaway view that shows the half tone protection structure of the utility model preferred embodiment.
Wherein, description of reference numerals is as follows:
100 half tone protection structures
3 screen cloths
30 openings
301 blade face
302 paste seal face
31 grenadine layers
32 emulsion layers
5 protective layers
7 things to be printed
T protective layer thickness
T emulsion layer thickness
W thing thickness to be printed

The non-Printing Zone of B
The specific embodiment
Below coordinate accompanying drawing and Reference numeral to do more detailed description to embodiment of the present utility model, make to have the knack of those skilled in the art and studying carefully after this description and can implement according to this.
Fig. 2 is the side view showing according to the half tone protection structure 100 of the utility model preferred embodiment.As shown in Figure 2, the utility model provides a kind of half tone protection structure 100, comprises a screen cloth 3 and a protective layer 5.
Screen cloth 3 is consisted of a grenadine layer 31 and an emulsion layer 32.Grenadine layer 31 is formed by many warps and many parallel weavings, and emulsion layer 32 is Wrapping net layer 31, and on it, is formed with multiple openings 30.Screen cloth 3 has a blade face 301 and and pastes seal face 302.Wherein, the position that is formed with multiple openings 30 on emulsion layer 32 is a Printing Zone A, and the periphery of Printing Zone A is a non-Printing Zone B.Described protective layer 5 is arranged in the blade face 301 of screen cloth 3, and is positioned at the non-Printing Zone B of A periphery, Printing Zone.
Half tone as above is when printing; that subsides seal face 302 and a thing 7 to be printed of its Printing Zone A are fitted; by scraper, from protective layer 5 to the blade face 301 of Printing Zone A of non-Printing Zone B, exert pressure and then scrape Yin Mo; make to print China ink and on printed material, stamp pattern by the opening 30 of hollow out, to reach the object of printing.Because non-Printing Zone B is provided with protective layer 5, when printing, scraper can directly not scrape on screen cloth 3, therefore also can not cause the wearing and tearing of screen cloth 3, and thus, the situation that can reduce screen cloth 3 breakages occurs.
The utility model has a thickness t at the set protective layer 5 of non-Printing Zone B, and the emulsion layer 32 of screen cloth 3 has a thickness T, and thing to be printed has a thickness W.In preferred embodiment of the present utility model, the summation of the thickness t of the emulsion layer 32 of the thickness T of protective layer 5 and screen cloth 3 should equal the thickness W of thing to be printed.
By half tone protection structure 100 of the present utility model, the situation that not only can reduce screen cloth breakage occurs, and increases the service life of screen cloth, more can therefore by minimizing, need to change the time of screen cloth and enhance productivity.In addition also can reduce, the loss of the slurry causing because of replacing screen cloth.
As seen from the above embodiment; value in the true tool industry of half tone protection structure provided by the utility model; but more than narration is only preferred embodiment explanation of the present utility model; all those skilled in the art can do other all improvement according to above-mentioned explanation, but these changes still belong in spirit of the present utility model and following defined the scope of the claims.
