Description
Technical field
The utility model relates to wrapping paper printing technology, is specifically related to a kind of paper apparatus for correcting.
Background technology
Along with social development and the raising of living standards of the people, consumer has higher requirement to the quality of product external packaging.The function of packing is no longer confined to hold product, has also been endowed deeper implication simultaneously, has almost become the symbol of value of the product and the foundation that consumer judges product quality.Therefore, tobacco productive corporation is attached great importance to the production of cigarette pack, and tobacco bale printing nature becomes a very important link in production of cigarettes industry.
The printing of tobacco bale mainly contains art paper and all kinds of paperboard.In order to make paper there is suitable stable tension force in printing process, before printing, must to roll web, carry out uncoiling processing with decoiling equipment.Paper has had fixing tension force in whole printing-flow, the precision of guarantee printing chromatography.After uncoiling, need to carry out dedusting debris removal processing to paper, can make like this printing surface bright and clean, avoid printed sheet to leak white or writing is unclear.Dedusting chip removing device is positioned at after uncoiler before printing machine, and the general principle of bleeding that adopts is removed paper scrap and dust.
When using halftone paper printing, because paper is thinner, after curling through unidirectional roller repeatedly, the phenomenon that the single printed sheet obtaining there will be paper bending is cut in printing, causes and cannot carry out the rear manufacturing procedures such as normal cross cutting.
Curling for overcoming art paper, can adopt the back of the body to be coated with technique, utilize the device of a colour cell on printing machine to transform, will wear paper method and adjust, make the reverse side of art paper become printing surface, and be coated with back coating liquid on this printing surface, to proofread and correct the distortion of paper.This method is curling very effective for eliminating paper.Back coating liquid plays and allows back side moisture absorption proofread and correct the effect of paper deformation, and the scope of selection is larger, as the stabilizing agent of water color ink etc.
But in conventional presses, do not have the special back of the body to be coated with machine, although and on the large-sized print equipment occurring in recent years, increased back of the body coating device, but equipment investment is huge, and after printing sheets thickness used increases, the simple method of using the back of the body to be coated with has been not enough to proofread and correct paper deformation, must be with by by paper warp and be coated with the bending that two kinds of modes of back coating liquid are corrected paper, therefore, for conventional presses, carry out architecture advances, making it possess the back of the body is coated with, the curling apparatus for correcting of the paper such as warp, extend the vitality of legacy equipment, make it have new vitality, it is the development of small and medium-sized printing enterprise adaptive technique, adapt to the optimal selection of unique characteristics.
Summary of the invention
For solving the Texturized technical problem of printing machine paper existing in background technology, the utility model provides a kind of printing machine paper curling apparatus for correcting, first this device carries out warp rectification by the paper to curling, being coated with afterwards back coating liquid corrects again, guarantee that the deformation of printing sheets is in allowed band, the subsequent technique of printing is carried out smoothly.
The utility model is by the following technical solutions: the curling apparatus for correcting of a kind of printing machine paper, comprises warp device and apparatus for coating;
Described apparatus for coating comprises ink organization of supply 1, printing mechanism 2, drying mechanism 3;
Described warp device comprises base 4, support 5, longitudinally dancing roll 6, laterally dancing roll 7, warp roller 8, secondary counter winding up roller 9; Described base 4 fixes on the ground, is a square-shaped frame, and in next station of uncoiler, support 5 is arranged on base 4, and connects each roller; Described longitudinal dancing roll 6 is parallel with each deflector roll of uncoiler, and longitudinally dancing roll 6 has two, is parallel to each other respectively and is arranged on longitudinal frame of base 4; Described horizontal dancing roll 7 is arranged on the horizontal frame of base 4; A described warp roller 8 is arranged on base 4 upper rights and lower-left diagonal, the setting height(from bottom) of secondary counter winding up roller 9 is lower than a warp roller 8, be arranged on base 4 upper lefts and lower-right diagonal position line, one time warp roller 8 is mutually vertical at depression angle with secondary counter winding up roller 9, is the angle of 45 ° with longitudinal dancing roll 6 and horizontal dancing roll 7; A described warp roller 8 and secondary counter winding up roller 9 are hollow roll, offer respectively densely covered pore on the periphery of the two, and end is connected with respectively tracheae 10, and after ventilation, gas blows out from pore.
For reduce paper by time resistance, the lower surface of the upper surface of the lower surface of described longitudinal dancing roll 6 and a warp roller 8 and secondary counter winding up roller 9 is in same level, the maintenance level that guarantees to try one's best when paper moves between differential roller, reduces the friction with roll surface.
During work, uncoiler is the expansion under certain speed and tension force condition by tubular paper, and keeps corresponding stable state, paper enters after warp device, first through the lower end of longitudinal dancing roll 6, maintenance level afterwards enters the upper surface of a warp roller 8, and now paper faces up; After walking around a warp roller 8, from the lower end of horizontal dancing roll 7, enter, on bring out, now paper faces up, then paper enters secondary counter winding up roller 9, walks around after secondary counter winding up roller 9, and the face down reverse side of paper upward, complete reversion, by being arranged on longitudinal dancing roll 6 of rear end, carry out tension stability again, adjust lateral shift, can enter the coating that apparatus for coating carries out back coating liquid.
Beneficial effect: the utility model carries out warp by warp device to paper and once corrects and be coated with the secondary of back coating liquid and correct, can be effectively for Texturized rectification of printing sheets of the kinds such as art paper, paperboard, guarantee printing quality, simultaneously, the utility model is also provided with specific position, height of each parts in warp device etc., guarantee the control to paper tension, frictional force in correcting process, guarantee the steady of operation, reduce energy consumption.
