The utility model provides a kind of Bracewell coater, comprise frame, frame is provided with the spray assembly that is used on supporter the spraying glued membrane, unreels portion, rolling portion, is provided with between spray assembly and the rolling portion to be used for the roller set roll-in supporter, adjustable clearance.
Adopt the simple in structure of Bracewell coater of the present utility model, simultaneously, after the spraying glued membrane glued membrane is carried out roll-in and can further make the glued membrane densification, and then increase the glue amount of covering of unit volume glued membrane, can obtain thinner while cohesive force glued membrane preferably.
Description of drawings
Fig. 1 is the schematic diagram of spray assembly of the present utility model;
Fig. 2 is the schematic diagram of Bracewell coater of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated.
A kind of Bracewell coater, comprise frame, frame is provided with the spray assembly that is used on supporter the spraying glued membrane, unreels portion, rolling portion, be provided with at least one group between spray assembly and the rolling portion and be used for the roller set roll-in supporter, adjustable clearance, be i.e. the roller set of running roller among Fig. 24 and running roller 5 compositions.By the roll extrusion of roller set, make glued membrane further fine and close for glued membrane.
Described spray assembly is the air-blast atomizing assembly, and described air-blast atomizing assembly is linked in sequence and is formed by air compressor 11, storage glue jar 14, fog-spray nozzle 19.
Be illustrated in figure 1 as the schematic diagram of spray assembly of the present utility model; Storage glue jar 14 tops of described air-blast atomizing assembly are provided with that charge door 15, bottom are provided with drain hole 16, the side is provided with the liquid level tube 17 that can have an X-rayed; Air compressor 11 is successively by air pressure adjustment part 12, air intake valve 13 and storage glue airtight connection of jar; Be sealedly connected with binder pipe 20 in the storage glue jar, an end of binder pipe 20 is located in the storage glue jar, and the other end of binder pipe 20 is connected with fog-spray nozzle 19.
Preferably, also be provided with fog-spray nozzle control valve 18 on the binder pipe between storage sebific duct and the fog-spray nozzle, fog-spray nozzle control valve 18 is connected with the flow signal processor, and the flow signal processor is connected with microcomputer.The flow signal processor feeds back to microcomputer with fluid flow, by microcomputer analysis, can further accurately control the fog-spray nozzle control valve, and then accurately the glue amount is sprayed in control.
Preferably, comprise that also at least one is used to regulate the dancer rools 3 of supporter tension force, described dancer rools is between portion of unreeling and roller set.In order to make conciliation support force tension force more even, more preferably, described dancer rools is 2, is respectively first dancer rools, second dancer rools, as shown in Figure 2, is sequentially with the portion of unreeling, first dancer rools 3, roller set, second dancer rools 7, rolling portion on the frame.The above-mentioned portion that unreels, the structure of rolling portion are that those skilled in the art is known, do not repeat them here, and therefore do not have shown in Figure 2.
Described supporter is that those skilled in the art is known, can be film, aluminium foil etc.
For make the glued membrane top roll after the roll-in is depressed from the roller set of adjustable clearance amount sizing material obtain reclaiming, can also comprise be positioned at the roller set below connect lacquer disk(-sc) 6, as shown in Figure 2.
Set forth with regard to the course of work of concrete Bracewell coater of the present utility model below, at first, close and store up all valves that the glue jar links to each other, open charge door 15 and in storage glue jar, inject liquid glue, injecting the height of liquid glue can observe by the liquid level tube of having an X-rayed 17 of storage glue jar side, the height that injects liquid glue will be higher than that end that binder pipe 20 is located at storage glue jar at least, otherwise liquid glue cannot be pressed into the binder pipe, and then cannot arrive fog-spray nozzle.Therefore, preferably, the end that binder pipe 20 is located in the storage glue jar is positioned at the bottom of storing up the glue jar.After adding liquid glue, close charge door.Open air compressor 11, reconcile the pressure of the pressure-air that air compressors provide, open air intake valve 13 by air pressure adjustment part 12, pressure-air is pressed into storage glue jar, glue in the storage glue jar is pressed into the binder pipe and arrives fog-spray nozzle under the pressure of pressure-air, and then the spraying glue.
Open fog-spray nozzle control valve 18 and reconcile the spray glue amount of fog-spray nozzle.
Preferably, also comprise flow processor, microcomputer, also be provided with fog-spray nozzle control valve (18) on the binder pipe between storage glue jar and the fog-spray nozzle, described fog-spray nozzle control valve (18) is connected with the flow signal processor, and the flow signal processor is connected with microcomputer.The flow signal processor feeds back to microcomputer with fluid flow, by microcomputer analysis, can accurately control the fog-spray nozzle control valve, and then accurately the glue amount is sprayed in control.By accurate control spray glue amount, can obtain thinner more uniform glued membrane.
Regulate the angle of fog-spray nozzle, preferably, the plane that fog-spray nozzle is formed perpendicular to supporter is so that the glue of fog-spray nozzle ejection can be sprayed on the supporter as much as possible.Liquid glue in the storage glue jar arrives fog-spray nozzle by the binder pipe under the pressure of pressure-air.Have and reconcile roller, reconcile the tension force that roller is regulated supporter, make the tension force of supporter moderate by regulating.The glued membrane of fog-spray nozzle ejection before by the rolling of rolling portion, is at room temperature dried glued membrane attached on the supporter, obtains carrying out rolling again behind the drying adhesive layer.If adopting is the liquid glue of non-quick-dry type, can also before rolling, carry out the glue dry-cure to the supporter that has glued membrane, as baking or ultraviolet ray irradiation, thereby obtain having the supporter of drying adhesive layer.
Reconcile roller set, be the running roller 4 among Fig. 2 and the gap of running roller 5, by the portion of unreeling supporter is emitted continuously, supporter is emitted direction continuously shown in the arrow among Fig. 2, supporter when the fog-spray nozzle by the glued membrane of spraying, the gap of passing roller set by the roller set roll extrusion after, through the rolling of rolling portion, the direction continuous moving direction of supporter not shown in the arrow among Fig. 2 obtains being coated with the supporter of glued membrane.Supporter is during through the roller set roll-in, and a spot of liquid glue is squeezed out by roller set, is dropped into along running roller 5 to connect in the lacquer disk(-sc) 6, recyclable this part liquid glue.Spraying finishes, and closes all valves, clears up by the remaining glue that drain hole 16 will store up in the glue jar.
Adopt Bracewell coater of the present utility model the thickness of glue-line can be reduced greatly, minimumly can be 0.5g/m
2, and because the glue-line even compact, when the supporter that has glue-line and other material carry out compound tense, delamination can not appear.Therefore, the use field of Bracewell coater of the present utility model is wide, and the field of compounding of multilayer film especially is as the production field of solar energy backboard film.
The above only is preferred embodiment of the present utility model, not in order to restriction the utility model, all any modifications of being done within spirit of the present utility model and principle, is equal to and replaces and improvement etc., all should be included within the protection domain of the present utility model.
