Summary of the invention
The purpose of this utility model: provide a kind of gentle version or intaglio plate flexible scraper, to improve printing quality, to reduce the scraper use cost.
The technical solution of the utility model is as follows.
A kind of gentle version or intaglio plate flexible scraper comprise that ribbon supports back of the body cutter (1), is characterized in that: a, support to carry on the back on cutter (1) at ribbon and be pasted with flexible strip belt body (2); For face contacts, wipe unnecessary printing ink by friction flexographic printing anilox roll (3) between a jiao (5) of b, described flexible strip belt body (2) and flexographic printing anilox roll (3); Perhaps, for face contacts, wipe unnecessary printing ink by friction gravure printing roller (4) between a jiao (5) of described flexible strip belt body (2) and gravure printing roller (4).
Preferably, one jiao (5) of described flexible strip belt body (2) are 70-120 degree angle (being preferably the right angle); Perhaps, described ribbon support back of the body cutter (1) is that thickness is that 0.5-3mm, width are carbon fiber or acrylic or the glass fibre reinforced plastics belt body of 25-85mm.
More preferably, described flexible strip belt body (2) is that thickness is that 0.8-3.5mm, width are that 5-35mm, shore hardness are that 85A-95A, density are the polyurethane strips belt body of 300-700kg/m3.
Compared with prior art, the utility model can produce following useful technique effect.
One, the utility model have been broken through the technology prejudice of traditional scraper.The tradition scraper is that rigid material is made, and more firmly makes an appointment, more sharp better, more wear-resisting better.Being that line contacts between cutting edge and flexographic printing anilox roll or gravure printing roller, is the mentality of designing of " firm with firm gram ", and cutting edge very easily weares and teares or is scratched, easily cause wiping residual, easily cause the printing quality problem.The utility model is acted in a diametrically opposite way, and adopts flexible material to make scraper, and cutting edge is not sharp, is that face contacts between cutting edge and flexographic printing anilox roll or gravure printing roller, is the design of " defeating a force with a tenderness ", and cutting edge is not easy to wear or be difficult for being scratched.Therefore, wiping totally, can not cause a large amount of printing quality problems.
Two, due to the utility model cutting edge is not sharp, be that face contacts between cutting edge and flexographic printing anilox roll or gravure printing roller, be the design of " defeating a force with a tenderness ", not easy to wear, be difficult for scratching.Therefore, the utility model flexible scraper is very durable, can greatly reduce the scraper use cost.
Three, experiment shows, the utility model flexible scraper is compared with background technology, also has the technological merit of following eight aspects.
1. can repeatedly grind reparation, have the service life of overlength, compare with existing rigid scraper, life is more than 16 times.
2. at the image-text area that contacts with gravure printing roller, flexible strip belt body (2) contacts closelyr, can not produce the picture and text angle that causes due to the scraper injustice, and the graphics resolution that therefore produces is higher.
3. flexible strip belt body (2) is very low to the wearing and tearing of forme, thereby has greatly extended the roller life-span, can ensure the priority uniformity of forme picture and text.
4. ribbon support back of the body cutter (1) is the high strength non-metallic sheet, can not produce bending deformation, and therefore flexible belt body is in level all the time on knife rest.And traditional steel spatula easily produces local or whole bending distortion, and is out of shape and can not recovers fully, so just easily produces the side-to-side shading of printing, and is out of shape due to local bending the cutter silk phenomenon that causes.
5. because flexible strip belt body (2) is flexible material, therefore the galling chip can not be produced, also the cutter silk phenomenon that chip causes can be therefore do not produced.Traditional steel spatula due to wearing and tearing, usually has metal fragment to enter in the middle of printing ink, then is taken to the scraper zone by printing ink, produces periodic cutter silk phenomenon.
6. because flexible strip belt body (2) is flexible material, fricative noise is little.
7. because flexible strip belt body (2) is flexible material, in printing process, can improve the viscosity of printing ink, this makes, and the thick China ink layer of printing becomes easier in intaglio printing.Traditional steel spatula can not adapt to full-bodied printing ink, and when ink viscosity improved, wiping was inhomogeneous, and can not scrape totally, even therefore the half tone degree of depth improves, well transfer of ink, can't realize the meticulous printing of thick China ink layer.
8. the adaptability of flexible strip belt body (2) in the high viscosity inks situation is very stable, therefore improving the intaglio plate degree of depth, improves in the situation of ink viscosity, can realize meticulous thick China ink layer printing.
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent, integrated optimization embodiment cited below particularly, and coordinate accompanying drawing to be elaborated.
