As a kind of improvement, the spacer screen of described triple-lap net building mortion is provided with the top net.
Described pressing device comprises twice through type shoe press apparatus.
As further 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.
Drying unit is a drying cylinder before described, and described drying cylinder comprises that three road lists are hung the arrangement drying cylinder and three 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.
As a kind of preferred, described surface size press is that film shifts sizing applicator.
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 shifting applying glue, adopt film belt calender to carry out press polish, adopt this device to produce coated white-top kraft liner board, 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 formula 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, covering is good, the advantage of paper not being had the machinery injury, 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, 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.
3, 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.
