Abstract
The utility model relates to a casting apparatus for producing a solar EVA film, comprising three rollers arranged on a rack side by side, wherein the surface of the intermediate roller of the three rollers is an uneven surface; the surface of the intermediate roller is uniformly provided with spiral grooves; and the roller at one side of the intermediate roller is a smooth roller and the roller at the other side of the intermediate roller is a rubber roller. When packaging a solar cell panel, gas between the surface of the solar cell panel and an EVA film is released along the spiral grooves of the EVA film, thereby avoiding bubble generation between the surface of the solar cell panel and the EVA film and effectively improving packaging quality of products.
Description
Technical field
The utility model relates to the production of solar energy EVA glued membrane, is the casting device that is used to produce solar energy EVA glued membrane specifically.
Background technology
At present, the EVA glued membrane is widely used in the encapsulation of solar panel, reaches the encapsulation requirement in order to make the EVA glued membrane, in its production process, must use casting device.The surface of three rods in the existing casting device generally is smooth surface, and therefore, the surface of the EVA glued membrane of this device production is a smooth.Because solar panel area in encapsulation process is bigger, be easy to generate bubble when encapsulating with ganoid EVA glued membrane, have a strong impact on the solar panel package quality.
The utility model content
The utility model has solved above-mentioned technical problem, and a kind of casting device of avoiding producing bubble in the solar panel encapsulation process is provided.
The technical scheme that the utility model solves the problems of the technologies described above employing is: a kind of casting device that is used to produce solar energy EVA glued membrane, comprise three rollers that are arranged side by side on frame, and the intermediate calender rolls surface of said three rollers is rough surface.
The utility model also has following additional technical feature:
Said intermediate calender rolls surface evenly is provided with helicla flute.
The roller of said intermediate calender rolls one side is a smooth roll, and the roller of opposite side is a rubber rollers.
Can know that from above technical scheme when the encapsulation solar panel, the gas between solar panel surface and the EVA glued membrane can be got rid of along the helicla flute of EVA glued membrane, thereby has avoided producing bubble between the two, has effectively improved the product package quality.
Description of drawings
Fig. 1 is the structural representation of a kind of optimal way of the utility model.
Embodiment
Specify the utility model below in conjunction with accompanying drawing 1:
This casting device comprises three rollers that are arranged side by side on frame 1; Intermediate calender rolls 2 surfaces of said three rollers evenly are provided with helicla flute 21; Form rough surface, when the encapsulation solar panel, the gas between solar panel surface and the EVA glued membrane can be got rid of along the helicla flute of EVA glued membrane; Thereby avoided producing bubble between the two, effectively improved the product package quality.The roller of said intermediate calender rolls one side is a smooth roll 3, and the roller of opposite side is a rubber rollers 4.Machine is when work; The EVA hot melt adhesive film is drawn by intermediate calender rolls, gets into the faying face of intermediate calender rolls and rubber rollers, and the EVA hot melt adhesive film is attached on the intermediate calender rolls; Under the pressuring action of rubber rollers; The surface of EVA glued membrane extrudes uniform spiral type decorative pattern, and the EVA glued membrane is walked around the faying face output of intermediate calender rolls from intermediate calender rolls and smooth roll subsequently, thereby produces the EVA glued membrane.
Above-mentioned execution mode only supplies to explain the usefulness of the utility model; And be not to be the restriction to the utility model; The those of ordinary skill in relevant technologies field; Under the situation that does not break away from the utility model spirit and scope, can also make various variations and modification, so all technical schemes that are equal to also should belong to the category of the utility model.
