Abstract
The invention discloses an environment-friendly precise coating method, and relates to the field of coating industry. A coating device comprises an enclosed adhesive storage bucket, an adhesive-feeding constant delivery pump, a coating die head, and a back adhesive wheel; the enclosed adhesive storage bucket is connected to one end of the coating die head through an enclosed pipeline, the adhesive-feeding constant delivery pump is arranged in the enclosed pipeline, and the other end of the coating die head is provided with the back adhesive wheel. The coating method comprises the following steps: transporting the adhesive for coating to an enclosed nozzle by the constant delivery pump, making a material to be painted run in a preset speed, and finally evenly spraying the adhesive on the surface of the material. The coating method has the following advantages: the transporting process and coating process are all carried out in an enclosed space, so the solvent evaporation can be effectively avoided; and at the same time, a constant delivery pump is adopted so as to solve the uneven membrane thickness of coating in the conventional coating technology.
Description
Technical field:
The present invention relates to application techniques field, be specifically related to a kind of environmental protection precision coating device and method thereof for application industry.
Background technology:
The gluing mode of coating industry is mainly take transfer coated, scraper for coating, reticulate pattern coating, the coating of line rod etc. as main at present.This type of coating is open type, and in production process, because glue groove is completely unlimited, its coater unit solvent strength is too high, to human body, environment and gluingly itself all have side effect in various degree.Meanwhile, along with the develop rapidly of each row such as optical articles, photovoltaic product, electronic material, its requirement to thickness evenness gets over tightly; Traditional gluing mode is mainly controlled gluing thickness with the gap between film and the edge of a knife, in addition traditional approach coating is open type coating, therefore passing in time of the solid content of glue and viscosity and progressively changing, this cannot guarantee thickness in whole production process completely.Therefore can adopt a kind of sealing coating method, solve on the one hand the environmental problem of the solvent evaporates of open type coating, can solve on the other hand the adhesive property that brings because of volatilization and change, make to be coated with gluing stable and uniform by special device becomes coating industry and needs at present the problem solving simultaneously.
Summary of the invention:
The object of this invention is to provide the accurate coating process of a kind of environmental protection, it can not only meet the solvent evaporates problem in each product coating process, can solve again because of the uneven problem of the glue face thickness volatilizing and other reasons causes.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: it comprises airtight adhesive bucket 1, takes turns 4 for glue constant displacement pump 2, coating die head 3, gum; Airtight adhesive bucket 1 is connected by closed conduit with one end of coating die head 3, and in the middle of closed conduit, is provided with for glue constant displacement pump 2, and the other end of coating die head 3 is provided with gum wheel 4.
Coating process of the present invention is: adhesive to be coated is delivered to closed spray chamber by constant displacement pump, and in the time that material moves under normal speed, the glue that send is evenly sprayed at material surface.
Described airtight adhesive bucket 1 can be closed atmospheric storage tank with pressure relief device, pressurized tank, normal pressure tank with breather valve; It can make adhesive with outside air without directly contacting, therefore can well stop the adhesive characteristic changing causing because of the reason such as solvent evaporates, moisture absorption.
Described can be servo-drive form, Frequency Converter Control type motor-driven for glue constant displacement pump 2, and its pump housing type can be screw pump, gear pump.It is for extracting glue glue bucket, by being delivered to extrusion die after pump supercharging, because whole induction system is closed type, therefore problems such as solvent-free volatilizations from airtight.
Described coating die head 3 can be single chamber form or multi-cavity form; Its die head can be that itself regulates or means for correcting with precision, can be also that itself does not regulate or means for correcting with precision; It in process of production, adhesive is delivered to this die head by constant displacement pump, and before extruding, adhesive, completely in die head closed chamber inside, only has slit of die orifice to contact with film and atmosphere, therefore relatively traditional open type scraper or the coating of three roller transfer types have the improvement of the property of change aspect solvent evaporates.
The present invention has following beneficial effect: can effectively solve solvent evaporates problem by closed conveying, airtight coating method, simultaneously by the quantitative membrane thickness unevenness phenomenon that can effectively solve tradition coating for glue mode.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present invention.
The specific embodiment:
Referring to Fig. 1, this specific embodiment by the following technical solutions: it comprises airtight adhesive bucket 1, for glue constant displacement pump 2, coating die head 3, gum wheel 4; Airtight adhesive bucket 1 is connected by closed conduit with one end of coating die head 3, and in the middle of closed conduit, is provided with for glue constant displacement pump 2, and the other end of coating die head 3 is provided with gum wheel 4.
This specific embodiment coating process is: adhesive to be coated is delivered to closed spray chamber by constant displacement pump, and in the time that material moves under normal speed, the glue that send is evenly sprayed at material surface.
Described airtight adhesive bucket 1 can be closed atmospheric storage tank with pressure relief device, pressurized tank, normal pressure tank with breather valve; It can make adhesive with outside air without directly contacting, therefore can well stop the adhesive characteristic changing causing because of the reason such as solvent evaporates, moisture absorption.
Described can be servo-drive form, Frequency Converter Control type motor-driven for glue constant displacement pump 2, and its pump housing type can be screw pump, gear pump.It is for extracting glue glue bucket, by being delivered to extrusion die after pump supercharging, because whole induction system is closed type, therefore problems such as solvent-free volatilizations from airtight.
Described coating die head 3 can be single chamber form or multi-cavity form; Its die head can be that itself regulates or means for correcting with precision, can be also that itself does not regulate or means for correcting with precision; It in process of production, adhesive is delivered to this die head by constant displacement pump, and before extruding, adhesive, completely in die head closed chamber inside, only has slit of die orifice to contact with film and atmosphere, therefore relatively traditional open type scraper or the coating of three roller transfer types have the improvement of the property of change aspect solvent evaporates.
This specific embodiment can effectively solve solvent evaporates problem by closed conveying, airtight coating method, simultaneously by the quantitative membrane thickness unevenness phenomenon that can effectively solve tradition coating for glue mode.
