Abstract
The utility model discloses a production equipment for coating white-top kraft liner boards, which comprises a three-folded screen shaping device, a squeezing device, a pre-drying device, a film transferring and glue-applying machine, a post-drying device, a hard press polishing device, a first scraper coating machine, a primary scraper post-drying device, a second scraper coating machine, a secondary scraper post-drying device, a soft press polishing device, a cooling device and a reeling and forming device. According to the utility model, after a base board is subject to the surface glue-applying or the coating, the surface of the base board is equipped with a smooth glue-applying layer or a coating layer. Then the base board is subject to the scraper coating twice. Therefore, the coating effect is better while the coating amount is low. Meanwhile, the coating layer of the base board is relatively uniform. In addition, the printing ink absorption uniformity of the kraft liner board is also improved by applying glue on the surface of the surface layer, so that the good printing effect of the kraft liner board is 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.
Coated white-top kraft liner board 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.Coated white-top kraft liner board 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, the coated white-top kraft liner board 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 coated white-top kraft liner board, 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: the deficiency at prior art exists provides the coated white-top kraft liner board that a kind of coating weight is low, coating is effective, printing quality is good production equipment.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of coated white-top kraft liner board production equipment comprises that rack-mounted successively triple-lap net building mortion, 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.
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.
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, the coating apparatus of the utility model coated white-top kraft liner board production equipment, 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, make 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, 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.
3, 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.
