Abstract
The utility model relates to an online back-coating device for a flexographic press, comprising a web, a printing unit formed by a rubber roller, a reticulated roller, a plate cylinder, an impression cylinder and an ink scraper. The online back-coating device is characterized in that a back-coating reticulated roller, a coating roll and the impression roller are arranged above the ink scraper; and the coating roll and a clutch presser are connected and are fixed on a back-coating frame. While the front printing is completed, the coating operation of gloss oil or varnish on the back of paper can be completed once, thereby solving the problem of bending deflection of the paper during the prior flexographic press. Through changes of parameters of the reticulated roller, the coating size of the gloss oil or the varnish can be adjusted at the right moment, thereby changing the coating thickness and meeting the requirement on the performance of different paper. Because of online coating, the online back-coating device for the flexographic press not only can reduce the operating energy consumption, mechanical abrasion and labor intensity of workers in the whole production process, but also can improve the working efficiency, and has the advantages of simple structure, convenient installation and maintenance, and lower manufacturing cost and operating cost. The online back-coating device for the flexographic press can be arranged on the front part or the back part of any printing unit.
Description
Technical field
The utility model relates to a kind of back of the body coating device of flexographic printing machinery, belongs to the printing machinery technical field.
Background technology
When utilizing traditional flexible printing machine to print, printing often occurs bending and deformation after cutting into Xiao Zhang, causes going up machine and normally prints.After multi-analysis research, find: because the paper that is adopted coating does not reach the particular requirement of this class print product, after stamping pattern and be coated with gloss oil, can cause physical indexs such as the positive and negative two sides of paper hydroscopicity, the coefficient of expansion to produce difference in the paper front.If directly customize the paper of single face thickening coating,, can increase cost because of paper price is high though can guarantee the quality after the paper coating to the paper producer.At this problem, best solution is to be coated with one deck gloss oil equably at the back side of paper, reducing the physical difference on its positive and negative two sides, thereby reduces or eliminate the flexural deformation of product, improves the quality of products, and reduces cost.The scheme that addresses this problem at present has two kinds: 1, carry out the secondary printing after finishing printing, to finish back side coating, but this method not only can make operation energy consumption, mechanical wear and the hand labor intensity of whole process of production increase, and production efficiency is low, and printing quality is difficult to guarantee.2, a rollover stand is set, so that finish back side coating on a printing element, this way has not only taken a printing element, greatly reduces the service efficiency of printing machine, and installs rollover stand additional can increase production cost on original printing machine.
Summary of the invention
The deficiency that can't normally print because of the paper bending distortion that occurs when overcoming existing flexible printing press printing, the utility model provides a kind of flexible printing press online back of the body coating device, can not only finish at the back side of paper coating gloss oil or varnish, and can disposable online carrying out, and cost is low, dismounting, easy for installation is used flexibly.
The technical scheme that its technical problem that solves the utility model adopts is: the online back of the body coating device of a kind of flexible printing press, comprise roll web, and the printing element that constitutes by rubber roll, anilox roll, plate cylinder, impression cylinder and Ink scraper, it is characterized in that above Ink scraper, being provided with the back of the body and be coated with anilox roll, applicator roll and roller platen, and applicator roll links to each other with the clutch pressurizer, and they all are fixed on the back of the body and are coated with on the frame.So that coating is implemented at the printing paper back side that printing element is come out, effectively prevent paper bending and be out of shape.
The base two ends of described Ink scraper are fixed on the back of the body and are coated with on two wallboards of frame, doctor is fixed on this base by knife rest, the back of the body that is positioned at doctor top is coated with the anilox roll two ends and is fixed on the back of the body by roll shaft and is coated with on two wallboards of frame, is coated with anilox roll coating gloss oil or varnish so that support or oppose.
The roll shaft of described roller platen by its two ends is fixed on the back of the body and is coated with on two wallboards of frame, and is positioned at the back of the body and is coated with the anilox roll top.
Described applicator roll is located at the back of the body by the roll shaft at its two ends and is coated with on two wallboards of frame, and be coated with between anilox roll and the roller platen at the back of the body, be equipped with respectively on the roll shaft at these applicator roll two ends by drawing, stretch cylinder or oil cylinder, an and clutch pressurizer that is configured to of fixed support cylinder or oil cylinder, action by cylinder or oil cylinder makes and is coated with anilox roll with the back of the body after the applicator roll displacement and roller platen is matched, so that gloss oil or varnish that the back of the body is coated with on the anilox roll pass to applicator roll, when the printing paper from printing element passes between applicator roll and roller platen, can implement coating from the back side of paper, effectively prevent paper bending and be out of shape.
The utility model compared with prior art has following advantage and effect: adopt such scheme, can be when finishing positive printing, the disposable coating work of finishing the gloss oil or the varnish of back side of paper, the problem of paper bending distortion when having solved existing flexographic printing.Be coated with the variation of anilox roll parameter by the back of the body, can adjust the size of gloss oil or varnish coating weight in good time, thereby change coating layer thickness, adapt to the different paper performance demands.Owing to be online the coating, can reduce operation energy consumption, mechanical wear and the working strength of workers of whole process of production, can increase work efficiency again, and it is simple in structure, installation, maintenance is convenient, and the complete machine layout speeds up, rationally, and production cost and operating cost are lower.Can be installed in the front portion or the rear portion of any one printing element, use, operate very flexible, convenient.
