Abstract
The utility model discloses production equipment for white surface coating kraft, and the production equipment comprises a three-wire forming device, a squeezing device, a pre-drying device, a film transfer sizing machine, a post-drying device, a hard calendering device, a curtain coater, a curtain coating post-drying device, a blade coater, a blade coating post-drying device, a soft calendering device, a cooling device and a coiling forming device, which are successively installed on a machine frame. The respective advantages of three coating modes are combined in the utility model, and a fine coating effect can be achieved under the precondition of a low coating weight so as to ensure that a coating layer is relatively uniform with high surface smoothness; and the ink absorbing uniformity of the kraft is improved by the top sizing of a surface layer so as to ensure that the kraft has a fine printing effect and meets the requirements of high-quality packaging and printing.
Description
Technical field
The utility model relates to paper making equipment, is specifically related to a kind of production equipment of coated white-top kraft liner board.
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, surface smoothness is high, printing quality is good production equipment.
For solving the problems of the technologies described above, the technical solution of the utility model is:
The 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 sizing applicator, back drying unit, hard calendering device, curtain formula coating machine, curtain formula coating back drying unit, scraper type coating machine, scraper coating back drying unit, soft calendaring device, cooling device, 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 curtain formula coating machine comprises two curtain formula curtain formula apparatus for coating.
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, curtain formula coating machine and scraper type coating machine, 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, after the coating of two curtain formula curtain formulas, again through a scraper coating, combine in three kinds of coating methods: film shifts applying glue or the coating covering is good, curtain formula coating good uniformity does not have the machinery injury to paper, and the good advantage of scraper coating surface flatness, the coating effect that can be issued in the prerequisite of low coating weight, make coating layer even relatively, the surface smoothness height, and also improved the uniformity of craft paper to absorption of inks at the top sizing of surface layer, thereby can guarantee that craft paper has good printing effect, can adapt to high-quality packing and printing demand.
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.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the structural representation of the utility model embodiment.
Among the figure, 1. triple-lap net building mortion; 11. top net; 2. pressing device; 3. preceding drying unit; 4. film shifts sizing applicator; 5. drying unit after; 6. hard calendering device; 7. curtain formula coating machine; 8. the curtain formula is coated with the back drying unit; 9. scraper type coating machine; 10. scraper is coated with the back drying unit; 11. soft calendaring device; 12. cooling device; 13. batch shaped device.
