Abstract
The utility model relates to an EVA (Ethylene Vinyl-Acetate Copolymer) glue film extruder. The extruder comprises a first template and a second template which are correspondingly folded, and a first end cover and a second end cover which are buckled at two ends of the first template and the second template, wherein cooling pipes are embedded in the first template and the second template; cooling liquids are filled in the cooling pipes. The extruder further comprises a water segregator, wherein two circulating ends of the cooling pipes are connected to the water segregator; and a circulating pump and a heat exchanging device are arranged between a general liquid inlet and a general liquid outlet of the water segregator. According to the extruder, the cooling pipes are creatively embedded in the first template and the second template; the two groups of the cooling pipes are combined together through the water segregator, so that the temperatures of the first template and the second template are controlled by the cooling pipes when the EVA melting glue bypasses an extrusion opening of the extruder to form a glue film, namely, the temperature control to the melting glue is more tended to be finely and linearly, thereby regulating the hardness of the glue film during primary molding. Thus, the quality of the produced EVA glue film is more stable, and the defective percentage is reduced; the smooth proceeding of a subsequent embossing process is ensured.
Description
Technical field
The utility model relates to a kind of EVA production equipment, is specifically related to a kind of EVA glued membrane extruder.
Background technology
If solar cell is directly exposed in air, its photoelectric transformation efficiency can decline very soon, loses practical value.Therefore, the research and development of the encapsulation material of solar cell are just very important.For reaching the object being isolated from the outside; adopt transparent, light aging resisting, adhesive property good, can bear atmosphere and change and there is flexible ethylene-vinyl acetate copolymer (EVA) glued membrane solar battery sheet is sealed; and be bonded together with levels protective material, form solar module.
EVA is a kind of typical random macromolecular compound, in its molecular structure, the irregular arrangement of substituting group on strand, in strand, the configuration of asymmetric carbon atom is not identical yet simultaneously, arrange also irregular, therefore it be that a kind of crystallinity is less, polarity and the higher material of pliability, it has good wellability in the time of heating and melting in addition, when cooling curing, having good flexibility, anti-stress cracking and adhesive property, is a kind of comparatively desirable material that can be used for solar cell package.
What EVA film forming adopted is extrusion forming process, and whole production line generally includes mixing plant, extrusion equipment, film pressing device, trimming unit and retractable volume equipment, completes batch mixing, material loading, extrudes, calendering, trimming, winding process.Determine will have of end product quality: raw material and formula, hot-melt extrusion process, and the several aspects of casting molding processes control, and in casting molding processes process, environment temperature and humidity is also an important step, suitable humidity and stable temperature, can reduce the stretcher strain of film, the tension force of controlling diaphragm.
At present, in EVA production process EVA micelle in water back by the colloid of melt into molten condition.Water back, normally by electrical heating, easily forms heat build-up in electrical heating, is difficult for temperature to control the quality that all can affect EVA glued membrane too high or too low for temperature.
Utility model content
The technical problems to be solved in the utility model is: propose a kind of EVA glued membrane extruder that can immediately regulate EVA melten gel temperature in water back fast.
The utility model is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of EVA glued membrane extruder, described extruder is by the first involutory template, the second template and be fastened on described first, first end cap at the second template two ends and the second end cap composition, after described the first template and the second template are involutory, are formed with for EVA melten gel and flow out the clearance channel that forms glued membrane at its seam crossing, described the first template and the second template are good thermal conductor, described first, the second template inside is embedded with cooling tube, in described cooling tube, be filled with cooling fluid, also comprise water knockout drum, the circulation two ends of described cooling tube are connected to water knockout drum, between total inlet of described water knockout drum and total liquid outlet, be provided with circulating pump and heat-exchanger rig.
Further, also comprise controller and the glued membrane X-ray calibrator that is arranged on described extruder glued membrane exit, the signal output part of described glued membrane X-ray calibrator is connected to described controller, and the control end of described controller is connected to the controlled end of described circulating pump.
Further, described cooling tube lays in meandering shape in described first, second template inside, and described circulating pump is for there being brush DC water pump.
The beneficial effects of the utility model are:
Extruder in the utility model is creationary is embedded with cooling tube in the first template, the second template, and by water knockout drum, two groups of cooling tubes is connected and combined.In the time that EVA melten gel forms glued membrane through the extrusion of extruder, cooling tube carries out temperature control to first, second template, more subtilized and linear to the temperature control of melten gel, the hardness when regulating glued membrane just to form, thereby make the quality of the EVA glued membrane of producing more stable, reduced defect rate.And be convenient to the carrying out of next step embossed technology.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, EVA glued membrane extruder of the present utility model is described further.
Fig. 1 is the structural representation of EVA glued membrane extruder in the utility model.
Fig. 2 is the longitudinal cross-section structural representation of EVA glued membrane extruder in the utility model.
Fig. 3 is the lateral cross section structural representation of EVA glued membrane extruder in the utility model.
The specific embodiment
Embodiment
Shown in Fig. 1, Fig. 2 and Fig. 3, the EVA glued membrane extruder 1 in the utility model, also comprises water knockout drum.
Also comprise controller and the glued membrane X-ray calibrator that is arranged on extruder glued membrane exit, the signal output part of glued membrane X-ray calibrator is connected to controller, and the control end of controller is connected to the controlled end of circulating pump.
The above-described embodiment that is not limited to of the present utility model, all employings are equal to replaces the technical scheme forming, and all drops in the protection domain of the utility model requirement.
