Abstract
The utility model discloses a spray glue application method and device for corrugated paper. The spray glue application device is mounted in an area before the corrugated paper enters into a first dryer in the postbaking process after being discharged from a glue applicator; the device comprises spray pipes; spray nozzles are arranged on the spray pipes; the input ends of the spray pipes are connected with input pipes; pressure gauges are arranged on the input pipes; the output ends of the spray pipes are connected with a return pipe; the number of the spray pipes is two; the two spray pipes are arranged in parallel at an interval, and are connected in parallel with each other through a pipeline; a plurality of spray nozzles are arranged on each spray pipe. Through the improvement on the prior art, the corrugated paper discharged from the glue applicator of a paper machine is subjected to spray glue application again, so that the surface of the corrugated paper is subjected to secondary film formation, which effectively improves the water resistance, reduces the moisture permeability of the surface of the corrugated paper, and finally reduces the moisture regain of the corrugated paper.
Description
Technical field
the present invention relates to the production field of corrugated paper, refer in particular to a kind of corrugated paper film forming spraying applications method and apparatus.
Background technology
Corrugated paper is the plate object be bonded by sheet lining and the corrugated paper of waveform being processed by Corrugator roller and formed, generally be divided into single wall corrugated board and double-layer corrugated cardboard two class, there is the advantages such as cost is low, quality light, easily processing, intensity is large, printing adaptability sample is excellent, storage convenient in carrying, therefore apply very wide.
In the production process of corrugated paper, need to carry out top sizing to corrugated paper, make corrugated paper surface form a skim, the effect of this tunic is the ring forcing up the targets and the WATER RESISTANCE that increase corrugated paper, enables corrugated paper in the environment that some are moist a little, keep the intensity of paper.At present applying glue film forming is carried out to the surface of corrugated paper, be all adopt disposable film forming usually, namely to corrugated paper top sizing once, carry out one-pass film-forming.Through facts have proved, carry out an applying glue film forming to corrugated paper at present, although increase the WATER RESISTANCE of corrugated paper to a certain extent, in a humid environment, corrugated paper can cause paper strength to be decayed due to the moisture absorption, is unfavorable for the preservation of corrugated paper.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of moisture permeability that effectively can reduce corrugated paper surface, the final corrugated paper spraying applications method and apparatus reducing the regain of corrugated paper.
In order to solve the problems of the technologies described above, one aspect of the present invention provides a kind of corrugated paper spraying applications method, and a kind of corrugated paper spraying applications method, comprises the following steps:
By through sizing applicator by the corrugated paper after an applying glue, before this corrugated paper enters post-drying drying process, again spraying applications process is carried out to this corrugated paper, makes this corrugated paper surface second film forming.Described 0.2 ~ 0.25MPa is remained on to atomisation pressure during the process of corrugated paper spraying applications.Described spraying applications process adopts chemicals polyvinyl alcohol.
On the other hand, the present invention also provides a kind of corrugated paper spraying applications device, this size applicator be arranged on corrugated paper from sizing applicator out after to the region entered before rear baking first drying cylinder, it is characterized in that, described size applicator comprises shower, and this shower is provided with nozzle, the input attaching input pipe of this shower, this input pipe is provided with Pressure gauge and control valve, and the output tipping of this shower has return duct.
Described shower is provided with two altogether, and these two showers are spaced and parallel setting, and these two showers are by pipeline connection parallel with one another.
Described shower is provided with at least two nozzles.
Spacing distance between described adjacent nozzle is 10 ~ 15 centimetres.
The diameter of described nozzle is 1 ~ 2 millimeter.
Described return duct is provided with return valve.
Described input pipe is also provided with flowmeter.
The present invention passes through improvements over the prior art, to the sizing applicator from paper machine out after corrugated paper carry out again spraying applications, make corrugated paper surface second film forming, the surface of original corrugated paper is made to form many skims, effective raising WATER RESISTANCE, reduce the moisture permeability on corrugated paper surface, the final regain reducing corrugated paper, successfully solve watt paper due to the moisture absorption and cause the attenuation problem of paper strength.
Accompanying drawing explanation
Accompanying drawing 1 is apparatus of the present invention installation site schematic diagram;
Accompanying drawing 2 is the catenation principle schematic diagram of apparatus of the present invention.
Detailed description of the invention
For the ease of the understanding of those skilled in the art, below in conjunction with accompanying drawing, the invention will be further described.
Present invention is disclosed a kind of corrugated paper spraying applications method and apparatus, by carrying out spraying applications again to the corrugated paper carrying out an applying glue and one-pass film-forming at sizing applicator, make this corrugated paper two-step film forming, effective raising WATER RESISTANCE, reduce the moisture permeability on corrugated paper surface, the final regain reducing corrugated paper.
Thus, the present invention discloses a kind of corrugated paper spraying applications method, comprises step: by through sizing applicator by the corrugated paper after an applying glue, before this corrugated paper enters post-drying drying process, again spraying applications process is carried out to this corrugated paper, make this corrugated paper surface second film forming.0.2 ~ 0.25MPa is remained on to atomisation pressure during the process of corrugated paper spraying applications, ensures that medicament can be sprayed at corrugated paper surface smoothly.Described spraying applications process adopts chemicals polyvinyl alcohol, and this medicine directly can be bought by market, is known products, is not described in detail in this.
In addition, present invention further teaches a kind of corrugated paper spraying applications device, this size applicator 2 be arranged on corrugated paper from sizing applicator 1 out after to the region entered before rear baking first drying cylinder 3, described size applicator 2 comprises shower 25, this shower 25 is provided with nozzle 26, the input attaching input pipe 22 of this shower 25, this input pipe 22 is provided with Pressure gauge 24, and the output tipping of this shower 25 has return duct 28.Shower 25 is provided with two altogether, and these two showers are spaced and parallel setting, these two showers pass through pipeline connection parallel with one another, the equal corresponding input pipe of attaching on every root shower, the input pipe connection parallel with one another of two showers, is connected with flowmeter 21 after being connected in parallel again.The input pipe 22 of shower 25 is also provided with control valve 23; convenient circulation and the shutoff controlling spray; return duct 28 is provided with return valve 27; by return valve 27 and return duct 28; preventing from having during spray piping longtime running silting generation up, also guaranteeing that carrying out circulation when shutting down to spray piping alters and wash.
Shower 25 is provided with at least two nozzles 26, and the spacing distance between adjacent nozzle 26 is 10 ~ 15 centimetres, this distance range guarantees to carry out spraying applications to corrugated paper uniformly.The diameter of nozzle is 1 ~ 2 millimeter, uses dosage optimization.And in the present embodiment, the pipeline of DN50 model selected by shower.
