Abstract
The utility model discloses three-net-stacking shaping equipment for producing coated kraft liner boards. The three-net-stacking equipment comprises a three-net-stacking shaping device, a pressing device, a light pressing device, a front drying device, a surface sizing machine, a rear drying device, a belt type calender, a curtain type coating machine, a curtain type coating and rear-drying device, a first blade coating machine, a first scraper coating and rear-drying device, a second blade coating machine, a second scraper coating and rear-drying device, a soft calendering device, a cooling device and a reeling shaping deviece which are mounted on a frame in sequence. The three-net-stacking shaping equipment improves the uniformity of printing ink absorbed by kraft liner boards through the surface sizing to the original of kraft liner boards; in coating, by combining the advantages of both curtain type coating and scraper coating, the surface smoothness of the coating layer is high, the coated kraft liner boards produced by the three--net-stacking shaping device has low substance weight, high strength and good bulk; and the three--net-stacking shaping equipment can meet the requirements of coated kraft liner boards with different printing manners and in different fields.
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 process units 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 triple-lap net former that a kind of surface smoothness height, printing quality are good, produce the coating craft paper.
For solving the problems of the technologies described above, the technical solution of the utility model is:
Produce the triple-lap net former of coating craft paper, comprise rack-mounted successively triple-lap net building mortion, pressing device, optical pressure device, preceding drying unit, surface size press, back drying unit, belt calender, curtain formula coating machine, curtain formula coating back drying unit, first knife type coater, first scraper coating back drying unit, second knife type coater, second scraper coating back drying unit, soft calendaring device, cooling device and batch shaped device.
As a kind of improvement, the spacer screen of described triple-lap net building mortion is provided with the top net.
Wherein, described pressing device comprises twice through type shoe press apparatus.
Drying unit is a drying cylinder before described, and described drying cylinder comprises that three road lists are hung the arrangement drying cylinder and four roads pair extension is arranged drying cylinder.
As a kind of preferred, described surface size press is that film shifts sizing applicator.
As a kind of preferred, described curtain formula coating machine comprises two curtain formula curtain formula apparatus for coating.
As a kind of preferred, described belt calender is the Valzone belt calender.
Owing to adopted technique scheme, the beneficial effects of the utility model are:
1, coating apparatus of the present utility model, comprise surface size press, curtain formula coating machine, first knife type coater and second knife type coater, after base board carried out the surface layer applying glue, there is a level and smooth glue application layer on the surface, at first be coated with through two curtain curtain formulas, and then through twice scraper coating, top sizing at surface layer, improved the uniformity of craft paper to absorption of inks, when coating, combine curtain formula coating good uniformity, the good advantage of paper not being had the machinery injury of covering, with the good advantage of scraper coating surface flatness, the collocation combination of preferred coating method, the coating effect that can be issued in the prerequisite of low coating weight makes coating layer even, the surface smoothness height can satisfy the requirement of craft paper to high printing performance; Because base board is through belt calender the time, long contact time with felt wrapped roll, press polish is effective, does not need bigger pressure, so the relative bulky of producing of craft paper, and craft paper is quantitatively little under the same thickness, can satisfy the demand of different field to craft paper.
2, the utility model is provided with the top net on the spacer screen of triple-lap net building mortion, has improved the dehydrating effect of base pastes, has improved the squeezing effect.
