Abstract
The utility model discloses a kind of sprayer unit for coating line, comprise hot air drier and drying cylinder, spray tank is provided with between hot air drier and drying cylinder, the pair of sidewalls of spray tank is provided with the bar seam that can pass for operation paper web, multiple spray nozzle is provided with in spray tank, spray nozzle is connected with water pipe, and described water pipe is provided with control valve.This sprayer unit amount of water being used for coating line is controlled, coating layer wetness degree and become paper surface gloss effective.
Description
Technical field:
The utility model relates to field of papermaking, is specifically a kind of sprayer unit for coating line.
Background technology:
In coating line, prior art adopts conventional method, at paper web through coating, the angle region entered after predrying between drying cylinder and pressure roller adds water, enter nip after paper coating is fully soaked again and obtain high-gloss surface by the drying cylinder minute surface casting mold of high temperature, traditional water feeding method cannot accomplish the accurate of full paper web, evenly, must excess add water to drying cylinder and pressure roller angle region in have sufficient overflow can ensure coated paper full width uniform wet, the mode that excess adds water makes the established coating surface of paper by destruction to a certain extent, part coating dissolves in again in water and runs off with overflow, not only add raw materials consumption but also cause the pollution of discharge of wastewater to environment.
Utility model content:
Technical problem to be solved in the utility model is, provides a kind of amount of water controlled, coating layer wetness degree and the sprayer unit for coating line becoming paper surface gloss effective.
Technical solution of the present utility model is, a kind of sprayer unit for coating line is provided, comprise hot air drier and drying cylinder, spray tank is provided with between hot air drier and drying cylinder, the pair of sidewalls of spray tank is provided with the bar seam that can pass for operation paper web, be provided with multiple spray nozzle in spray tank, spray nozzle is connected with water pipe, and described water pipe is provided with control valve.
To adopt after above structure compared with prior art, the utility model has the following advantages: come alternatively traditional to add water-wet with spray nozzle spray humidification, spray amount according to coating layer wetness degree and can become the adjustment of paper surface gloss effect, control, avoid paper coating to be washed away loss by water, improve paper quality.
As preferably, described spray nozzle faces the direction running paper web.Wettability effect is good.
Accompanying drawing illustrates:
Accompanying drawing is structural representation of the present utility model.
Detailed description of the invention:
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in the figure, a kind of sprayer unit for coating line, comprise hot air drier 1 and drying cylinder 2, spray tank 3 is provided with between hot air drier 1 and drying cylinder 2, the pair of sidewalls of spray tank 3 is provided with the bar seam 5 that can pass for operation paper web 4, and be provided with multiple spray nozzle in spray tank 3, spray nozzle is connected with water pipe, described water pipe is provided with control valve, and spray nozzle faces the direction running paper web 4.Employing predry paper web after coating arranges spray nozzle 3 before entering drying cylinder and pressure roller, replace and traditional add water-wet mode, executing water to coating layer spraying makes whole coating process all-the-time stable controlled, and washed away leakage because paper coating does not exist by water, thus product quality improvement more obvious than traditional approach, stable production process is reliable, after employing the utility model, the coating of paper web coating does not run off completely in addition, effectively can reduce production cost and there is no the discharge of waste water completely, stop the pollution to environment.
Below be only described with regard to the utility model preferred embodiment, but can not be interpreted as it is limitations on claims.Every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion, include within scope of patent protection of the present utility model.
