Abstract
The utility model discloses a four-fleeting coating kraft paper production device comprising a four-fleeting forming device, a squeezing device, a front drying device, a film transfer sizing machine, a rear drying device, a hard calendaring device, a first blade coating machine, a first-channel blade rear drying device, a second blade coating machine, a second-channel blade rear drying device, a soft calendaring device, a cooling device and a coiling and forming device, which are sequentially mounted on a rack. After sizing or coating is performed on the surface layer of a base paper board, the surface has the smooth sized layer or the coated layer, then blade coating is performed twice, the good coating effect can be achieved on the premise of low coating quantity, the coated layer is relatively uniform, the surface sizing on the surface layer can further improve the uniformity in absorption of printing ink of kraft paper and the good printing effect of the kraft paper can be further ensured.
Description
Technical field
The utility model relates to paper making equipment, is specifically related to a kind of production equipment that is coated with craft paper.
Background technology
Craft paper generally adopts waste paper or wood pulp to make as raw material, generally is divided into bottom and surface layer or is divided into bottom, sandwich layer and surface layer, and cost is lower, and intensity is higher, but rough surface, printing quality is poor.At present a lot of commodity packagings generally adopt craft paper to make packaging material in order to save cost.But, use craft paper can not satisfy the demand of part exquisiteness, expensive goods along with the live raising of grade and of people to the pursuit of packaging quality.
The coating craft paper is good because of its intensity height, single face whiteness height, printing performance, and becomes a kind of broad-spectrum packaging material day by day.The coating craft paper generally includes a surface layer, a lining and a bottom, and then on surface layer coating composition, owing to adopted layer structure, surface layer, lining, bottom can adopt different fibre stufves, and for example surface layer can adopt wood pulp one time, and remaining layer can adopt the secondary stock slurry, thereby, coating craft paper production cost is low, and the slurrying pollutional load is little, is fit to very much the national conditions that China's nature timber resources lacks.At present, though it is a lot of to produce the production equipment of coating craft paper, have but that production efficiency is low, production cost is high, be coated with different problems such as weak effect and poor product quality.
Summary of the invention
Technical problem to be solved in the utility model is: at the deficiency that prior art exists, provide the four folded net coating craft paper production equipments that a kind of coating weight is low, coating is effective, printing quality is good.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of four folded net coating craft paper production equipments comprise that rack-mounted successively four folded net building mortions, pressing device, preceding drying unit, film shift drying unit, soft calendaring device, cooling device behind drying unit behind sizing applicator, back drying unit, hard calendering device, first knife type coater, one scraper, second knife type coater, the two road scrapers, batch shaped device.
Wherein, described pressing device comprises twice through type shoe press apparatus.
As a kind of improvement, one of described twice through type shoe press apparatus presses roller and two depress rollers are the boots roller, and two press on the roller and to use the shoe press belt, and one presses on roller, a depress roller and two depress rollers and uses press felt.
Wherein, described preceding drying unit is a drying cylinder, and described drying cylinder comprises the two arrangement drying cylinders of hanging of three road lists extension arrangement drying cylinders and three roads.
Owing to adopted technique scheme, the beneficial effects of the utility model are:
1, coating apparatus of the present utility model, comprise that film shifts sizing applicator, first knife type coater and second knife type coater, to base board carry out the surface layer applying glue or the coating after, there are a level and smooth glue application layer or coating layer in the surface, carry out twice scraper coating again, the coating effect that can be issued in the prerequisite of low coating weight makes coating layer even relatively, and also improved the uniformity of craft paper, thereby can guarantee that craft paper has good printing effect to absorption of inks at the top sizing of surface layer.
2, one boots of twice through type shoe press apparatus of the present utility model press roller and two road boots depress rollers are the boots roller, two road boots press and use the shoe press belt on the roller, one boots press on roller, one boots depress roller and the two road boots depress rollers and use press felt, two road boots press and use the shoe press belt to improve the surface smoothness of the base board after the squeezing on the roller, therefore saved the optical pressure operation after the squeezing, simplified production stage, reduce energy consumption, reduced equipment investment and equipment maintenance cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
