Description
Technical field
The utility model relates to silk-screen half tone making apparatus, particularly relates to a kind of large-scale silk-screen half tone exposure device.
Background technology
The need of production of silk-screen half tone by exposure by picture and text photocopy on the material such as screen cloth scribbling photosensitive thing, last layer photoresists post-drying is coated with on silk-screen half tone surface, to have above the film of image covers, by strong illumination film, the image on film is exposed photocopy on the photoresists on plate.And when making large-scale silk-screen half tone, its size has 3 ~ 4 meters wide, 5 ~ 6 meters long, and traditional exposure machine cannot process at all, there will be the situation that exposure is uneven, partial exposure is not enough or over-exposed.The uneven silk-screen half tone of exposure can have a strong impact on printing quality, the silk-screen half tone energy faithful reappearance original copy of correct exposure, avoids that pattern line is unintelligible, look drift phenomenon appears in site chromatography.Over-exposed meeting causes " optical diffraction " phenomenon, affects half tone edge definition and resolving power, and under-exposure causes printing quality poor, wastes raw material, and half tone is difficult to reclaim.
Utility model content
The technical assignment of technical problem to be solved in the utility model and proposition improves prior art, a kind of large-scale silk-screen half tone exposure device is provided, solve large-scale that exposure of silk-screen half tone in current technology, easily exposure is uneven affects printing quality problem.
For solving above technical matters, the technical solution of the utility model is:
A kind of large-scale silk-screen half tone exposure device, comprise rack and light source, it is characterized in that, described rack comprises front frame and after-frame, and front frame is frame structure, and tempered glass is inlayed in face, and front frame is vertically fixed, after-frame and front frame are connected through the hinge at top, screen printing net plate be positioned over after-frame and front frame fasten after confined space in, light source is positioned over front frame front and aims at screen printing net plate and carry out exposing operation.Large-scale silk-screen half tone exposure device described in the utility model arranges large-scale framework, and be placed on framework by needing the large-scale silk-screen half tone of exposure-processed to erect, whole framework is positioned at black room, utilizes light source to carry out exposure-processed to silk-screen half tone.Silk-screen half tone can be fixed by the rack of front and back folding easily, prevent it from toppling over, the position of light source and light intensity can arbitrarily adjust, make whole silk-screen half tone can be even by light source irradiation, thus guarantee to expose uniformity coefficient, avoid the situation occurring that partial exposure is not enough or over-exposed, improve printing quality.
Further, described after-frame is frame structure, and on face, device has curtain, and curtain evenly offers pore, and pore is connected to vacuum plant by tracheae.In order to improve photocopy quality, reduce the shade that ray cast produces, vacuumized in the region before front frame and after-frame, having picture and text film and being exposed silk-screen half tone of making to be stacked together exists together in subnormal ambient, be close to seamless as far as possible, make image exposure photocopy accurate.
Further, described front frame and after-frame are provided with locking device in frame edge, and before improving, frame and after-frame fasten rear tight ness rating, improve sealing effectiveness, and the vacuum tightness before ensureing between frame and after-frame improves exposure quality.
Further, described front frame and after-frame are provided with sealing strip in the mosaic of framework, improve sealing effectiveness further, ensure exposure quality.
Further, described front frame is provided with the base support and crossbeam that prevent from toppling over, improves the stability of whole large-scale silk-screen half tone exposure device, avoids the accident of toppling over, and improves safety in utilization.
Further, described light source adopts metal halid lamp, high-pressure sodium lamp or fluorescent light, select different light sources according to the difference of photosensitive material, control the output power of light source, the distance of light source and half tone and the wavelength of light source, and grasp the time shutter, improve plate-making quality.
Compared with prior art, the utility model advantage is:
Large-scale silk printing screen clamp bar is contained in rack by large-scale silk-screen half tone exposure device described in the utility model, the distance of light source and half tone, the wavelength of light source and time shutter can control easily, improve the exposure uniformity coefficient of large-scale silk-screen half tone, improve plate-making quality, improve final printing quality;
The utility model structure is simple, is easy to manufacture, and cost of manufacture is low, high financial profit.
