Radiator is fixedly mounted on slot, transparent surface lower central position is inversely installed in U-shaped light trough；Installation ballast and triggering on the outside of workbench
Device.Because traditional printer is designed using box-type, light is closed in illumination, in exposure process, the high temperature that fluorescent tube generates, no
It can completely eliminate, be unfavorable for cooling down, and box-type design printer size is small, effective exposure area is limited, is unable to satisfy production
The demand of ultra-large type halftone such as designs printer using large-size box formula, and at high cost, workmanship is complicated, and Feasible degree is low.
As market is increasing to ambetti, motorbus paint glass demand, traditional handicraft uses small desk
Because the effective exposure area of desk-top exposure machine is small when printer makes large-scale halftone, printing down needs are performed in multiple times, during printing down
It cannot vacuumize, the film cannot be fitted closely with halftone, and exposure machine intensive ultraviolet light generates diffraction, the portion that originally should not be exposed
Point, it is irradiated by ultraviolet light.After emulsion is penetrated by strong UV illumination, photochemical reaction is generated, emulsion is cured, then under
It should be rinsed in development (mixing two fluids with high-pressure water gas, spray to the screen painting face after the exposure) processing procedure come clean
Exposure emulsion can not be rinsed well because of the diffraction of light source, and fine lines cannot thoroughly develop, aliasing, and halftone is fine
Lines production encounters bottleneck.

Plate-making frame 51 avoids manually lifting bottom plate 61, reduce labor intensity, reduce security risk, prevent for placing bottom plate 61
Only industrial accident, while facilitating and combining coated PS version and the film.
Square tube, which is stood up, keeps guiding performance good, and idler wheel 63 is not easy to derail, and square tube is cheap, price is convenient, intensity is high.
When work, being fixed after coated PS version, film typesetting placed in the middle with 3M adhesive tape, halftone P faces upward, and is placed on
62 middle position of rubber slab shines chase 1 at this time and is in horizontality, and the piston rod of lifting cylinder 31 is in retracted mode, hook
32 are located at the top of connecting rod 65；Bottom plate 61 is shifted on printing down guide rail 24 along plate-making guide rail 52, is entered by printing down guide rail 24
The bottom of chase 1 is shone, positioning plate 25 makes bottom plate 61 be placed exactly in 11 lower section of glass, and is located at the center for shining chase 1.In bottom plate 61
It is inserted into during shining chase 1, starts lifting cylinder 31, lifting cylinder when bottom plate 61 is soon completely inserted into positioning plate 25
31 piston rod drives 32 decline of hook, and hook 32 drops to the lower section of connecting rod 65, then moves on bottom plate 61, bottom plate 61
When being moved at positioning plate 25, connecting rod 65 is located at 32 top of hook, then starts lifting cylinder 31, the piston of lifting cylinder 31
Bar rises, and hook 32 hooks connecting rod 65, rises cylinder 31 and continues up lifting connecting rod 65, lifting cylinder 31 presses bottom plate 61
Space tightly on glass 11, between gasket seal base 61 and glass 11.Then starting vacuum pump 7 takes out glass 11 and bottom plate
Air between rubber slab 62 and glass 11 is cleaned by the air between 61, fits closely halftone and glass 11；Work as pressure
It expresses setting value (setting value is usually 300mm mercury column) and starts tumble cylinder 23 afterwards, shine chase 1 and rotated around bearing block 22, turned over
Rotaring cylinder 23 makes solarization chase 1 slowly become vertical state from horizontality, shines chase 1 and fluorescent tube keeping parallelism.According to halftone
Size, the distance between adjustment light source and solarization chase 1, makes light source that halftone be completely covered, and is then set according to halftone film thickness, yarn thickness
Exposure energy, starting " exposure countdown button ", after countdown, fluorescent tube starts automatically, is exposed operation, is located at printing down
Illumination instrument on frame 1 starts to incude light energy.After light energy reaches setting value, end is made in exposure by oneself.After end exposure,
Start tumble cylinder 23, tumble cylinder 23 makes solarization chase 1 slowly return to horizontality from vertical state.It is then switched off vacuum pump 7,
Then start lifting cylinder 31, the piston rod of lifting cylinder 31 drives 32 decline of hook, and idler wheel 63 is returned on printing down guide rail 24, hung
Hook 32 unclamps connecting rod 65, starts lifting cylinder 31, lifting cylinder 31 after bottom plate 61 is moved a small distance to plate-making frame 51
Piston rod rise, hook 32 is located at the tops of connecting rod 65, and the movement that hook 32 does not influence bottom plate 61 continues along printing down guide rail
24 is mobile to plate-making frame 51 by bottom plate 61, and bottom plate 61 is shifted on plate-making guide rail 52, halftone is carried off, takes the film, remaining process off
According to conventional graphic arts technological operation.
