Abstract
The utility model relates to a scraper for screen printing, which comprises a scraper bracket (3) and a scraper main body (1) arranged in the scraper bracket (3). The scraper bracket (3) consists of a first clamping piece (31) and a second clamping piece (32); the scraper main body (1) is fixed between the first clamping piece (31) and the second clamping piece (32), wherein, at least one spring (2) is positioned between the scraper main body (1) and the scraper bracket (3) and the two ends of the spring respectively lean against the scraper main body (1) and the first clamping piece (31).
Description
Technical field
The utility model relates to a kind of serigraphy scraper.
Background technology
The slurry coating that uses when color plasma display is made is generally undertaken by dual mode:
1, silk screen print method promptly is printed onto glass baseplate surface or figure the inside by printing machine with slurry, thereby forms overlay or bargraphs.
2, Coater method, promptly the mode by Coater is the surface of slurry coating at glass substrate, thereby forms overlay.
As the silk screen print method that is most widely used, technology is the most ripe, of paramount importance when slurry coating is exactly scraper used when printing.Traditional scraper is that employing hardness is that 80 polyurethane rubbers of spending are made, grind the printing termination becomes the trapezoidal or sword shape of 45 degree, pressure when the problem that this scraper exists is printing is regulated and can only be finished by printing equipment, thereby cause scraper elastic force deficiency, often need twice above printing, because the strain problem of screen through printing forme and the elastic deformation of polyurethane rubber scraper make scraper contact imprecision with silk screen, be easy to produce entire slurry and apply irregular simultaneously.
By using the new phosphors scraper, improve the discharge-amount of fluorescent powder paste material, the uniformity coefficient of coating on the other hand, the luminosity of whole screen is improved, this is open in the CN2758070Y communique.But the hardness of resilient sleeper-bearing was fixed during above-mentioned serigraphy was made of scraper, was not easy to regulate the size of squeegee pressure during printing, and certain limitation is arranged.
The utility model content
In order to address the aforementioned drawbacks, the purpose of this utility model is to provide a kind of serigraphy scraper, it comprises scrapes knife support and is arranged on the scraper main body of scraping in the knife support, this is scraped knife support and comprises first intermediate plate and second intermediate plate, this scraper main body fixes between this first intermediate plate and second intermediate plate, wherein, scrape at this scraper main body and this and to be provided with at least one spring between knife support, the two ends of this spring are resisted against respectively on this scraper main body and this first intermediate plate.
Preferably, the height of this first intermediate plate is greater than the height of this second intermediate plate.
Preferably, this first intermediate plate than second intermediate plate high 3 to 10cm.
Preferably, scrape at this scraper main body and this and to be provided with 10 to 100 groups of springs between knife support, every group of spring is made up of 2 to 5 springs.
Preferably, this spring is arranged in 2 to 5 rows.
Advantage of the present utility model is, because the utility model is provided with spring in a side of scraper main body, and first intermediate plate of scraping knife support is than the second intermediate plate height, guaranteed the hardness of scraper when printing, simultaneously scraper and silk screen are combined closely, can guarantee that silk screen and glass baseplate surface well coincide, and the pressure can adjust printing automatically along with the state on surface the time.The structure of scraper main body has increased the contact area of scraper and silk screen, first intermediate plate of scraping knife support can increase the pressure of printing well, add the regulating action of spring, the slurry justifying good uniformity that prints out, thereby guaranteed the luminous uniformity of the whole screen of PDP, and do not had residual slurry on the through printing forme of printing back.

The specific embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are further described.
Fig. 1 shows side view of the present utility model.Fig. 2 shows vertical view of the present utility model.Fig. 3 is a profile of the present utility model.The utility model relates to a kind of serigraphy scraper, comprise and scrape knife support 3 and be arranged on the scraper main body 1 of scraping in the knife support 3, this is scraped knife support 3 and comprises first intermediate plate 31 and second intermediate plate 32, this scraper main body 1 fixes between this first intermediate plate 31 and second intermediate plate 32, wherein, scrape at this scraper main body 1 and this and to be provided with at least one spring 2 between knife support 3, the two ends of this spring are resisted against respectively on this scraper main body 1 and this first intermediate plate 31.The height of this first intermediate plate 31 is greater than the height of this second intermediate plate 32, and particularly these first intermediate plate, 31 to the second intermediate plates 32 high 2 are to 10cm.Scrape at this scraper main body 1 and this and to be provided with 10 to 100 groups of springs 2 between knife support 3, every group of spring is made up of 2 to 5 springs 2.This spring 2 is arranged in 2 to 5 rows.
The size of spring force can also be finely tuned by screw, requires and technology Yu degree with the elastic force that satisfies printing.The discharge-amount and the elastic force that use the utility model to carry out the slurry printing mainly are to be controlled by spring 2 and this first intermediate plate 31 against this scraper main body 1.
The utility model compared with prior art, the justifying uniformity high conformity of the slurry figure that prints out, and can control the degree of the discharge-amount of slurry by the size of adjusting spring pressure, particularly when printing fluorescent material, can form good shape, thereby guarantee the luminous uniformity uniformity of the whole screen of PDP; Slurry coating is even during printing fluorescent material, does not have residual slurry on the through printing forme, thereby has guaranteed the luminous uniformity of the whole screen of PDP.Because pressure can carry out suitable adjustment along with the flexibility of glass surface, squeegee pressure can be floated simultaneously, the contact gear ratio on scraper main body and through printing forme surface relaxes, and has increased the access times and the life-span of through printing forme.
The above is a preferred embodiment of the present utility model only, is not to be used for limiting the scope that the utility model is implemented.Be that all equalizations of being done according to the utility model claim change and modification, be all the utility model claim and contain.
