Description

The digital net making machine of plain net

Technical field

The utility model relates to the printing equipment technical field, relates in particular to a kind of digital net making machine of stamp plain net.

Background technology

Dyeing is before carrying out textile printing, all to make net earlier, traditional plain net mostly adopts sensitization system net method system net, in this way before the system net, utilize computer color splitting software earlier stamp flower type original copy to be carried out color separation by different colors, every kind of color after the color separation forms different images, with the image transfer of the color of the same race after the color separation to black and white film; With the water soluble photosensitive blade coating to plain net, low temperature drying in the darkroom, again above-mentioned color separation black and white film is coated on respectively on the plain net (one throw the net a kind of color), utilize the plain net after ultraviolet strong illumination coats black and white film, light is through the photoresists on the no image section irradiation plain net on the color separation black and white film, sensitising agent in the photoresists is met light generation sclerous reaction, i.e. exposure, make photoresists generation qualitative change and water insoluble, stop up mesh, this part will become the slurry blocking part in the textile printing; And the part of the black image on the color separation black and white film sees through because of stoping light, and the qualitative change reaction does not take place the photoresists of corresponding this image section on the plain net, and is promptly unexposed; When putting into water, unexposed photoresists are met instant the separating of water and are come off, and show online original mesh with the plain net after the exposure, promptly develop, and this dissolving zone that comes off becomes target flower type.The defective that traditional plain net production method exists is: system net operation is many, and manufacturing speed is slow, and technology is numerous and diverse, needs with a large amount of films, and the consumptive material height can not adapt to keen competition situation day by day in the world.

In recent years, wax spray, inkjet screen-making technology have been developed both at home and abroad, this technology has been saved the bag sheet process before film and the exposure, but owing to wax spray, ink-jet all will be used a lot of shower nozzles, and the injection diameter of shower nozzle minimum (≤0.05mm), be easy to cause shower nozzle to stop up, maintenance difficult causes stopping production; Consumable material prices such as cured of used ink and black solid are high, and need be subjected to the source control of blockade on new techniques country from external import, and wax spray, inkjet screen-making technology are difficult to apply.

In recent years, also developed the making net by laser technology, has high-octane etching laser beam after utilizing focusing, curing glue on the plain net predetermined point is vaporized, etch stamp flower type, though the making net by laser technology has also been saved film and the preceding bag sheet process of exposure, the deficiency of its existence is: because laser focusing etching employing is the pointwise etching, efficient is very low; Lack security, there is great potential safety hazard in the high-octane light beam combustible that very easily ignites for the combustible that exists in the stamp place; Cost height, laser generator derive from external import, and price is high, and there is the characteristic of optical energy attenuation in laser generator, and it is more complicated that the decay later stage is changed laser generator, spends high.

The utility model content

Technical problem to be solved in the utility model is: provide the low plain net of a kind of efficient height, cost digital net making machine.

For solving the problems of the technologies described above, the technical solution of the utility model is: the digital net making machine of plain net, comprise frame, and described frame is provided with the workbench that is used for fixing plain net; The both sides of described workbench are provided with Y to guide rail, and described Y is equipped with the walker that is driven by first power set on guide rail; Described walker is provided with X to guide rail, and described X is equipped with the UV photoetch head that is driven by second power set on guide rail; Described UV photoetch head comprises a mount pad, described mount pad is provided with a LCDs that is used for roll display bar shaped color separated image, the width of described bar shaped color separated image equates with effective display width of LCDs, the parallel installation of described LCDs with plain net, the rotating direction of described bar shaped color separated image is consistent with directions X; Also be provided with the UV light source on the described mount pad, described LCDs between UV light source and plain net, described UV light source by a light-shield cover with the direct projection of UV light on described LCDs; Described first power set, second power set, UV light source and LCDs are electrically connected with computer respectively.

As optimized technical scheme, described UV light source is an area source.

As optimized technical scheme, described first power set and second power set comprise a servomotor respectively.

Owing to adopted technique scheme, compared with prior art, the beneficial effects of the utility model are: when utilizing the digital net making machine system net of plain net of the present utility model, the plain net of gluing is fixed on the workbench, the bar shaped color separated image that obtains behind computer color splitting and the partitioned computer is imported local computer, the described bar shaped color separated image of computer control is rolled at described LCDs upper edge directions X in the mode of scroll bar and is play, drive the speed that described UV photoetch head moves along directions X and the rolling speed equal and opposite in direction of scroll bar by second power set, direction is opposite, and scroll bar is actionless with respect to plain net; Meanwhile, shine described LCDs with the UV light source that is installed on the described UV photoetch head, the UV light that sees through described LCDs shines the water soluble photosensitive sensitization that makes irradiated area on the plain net on the plain net and solidifies, stop up mesh, this zone will become the white background part behind the textile printing; UV photoetch head moves continuously along directions X, behind the intact bar shaped subregion of etching, driving walker by first power set makes UV photoetch head move a normal width along the Y direction, carry out the etching of next bar shaped subregion again, repeat described directions X etching step and Y direction line feed step, until the corresponding to pattern of the black white image that on plain net, etches a width of cloth and corresponding chromatography; Etching finishes, and flushing is developed, and is not come off by the dissolving of the water soluble photosensitive of UV light sensitization on the plain net, exposes original mesh, and this dissolving zone that comes off becomes target flower type.

Because whole system network process does not need black and white film to come load image as medium, does not more need manually to wrap sheet, LCDs has played the effect of electronic image memory device, has reduced consumptive material greatly, and cost falls in less manpower simultaneously; Carry out the bar shaped etching because UV photoetch head is the effective display width with LCDs as normal width, compare with the pointwise etching of adopting the making net by laser technology, efficient is greatly improved; Adopt digital net making machine of the present utility model and net making method system net, avoided being prone to defects such as sand holes because of the plain net that manual operation brings, the steady quality of finished product plain net, the defective product rate reduces greatly.
