Abstract
The utility model discloses a casting device for a solar ethylene vinyl acetate (EVA) film machine. The casting device comprises a traction frame and three rolls parallelly arranged on the traction frame, wherein two traction rolls are driven by a motor. The casting device is characterized in that: a traction roll is a patterned roll of which the surface is provided with a thread groove; another traction roll is a smooth roll with a smooth surface; the third roll is a high-temperature resistant rubber roll; the patterned roll is arranged in the middle; the rubber roll is arranged on the traction frame in a sliding way through a slide seat, and is pushed by a power cylinder; and the traction frame is arranged on a lifting mechanism. By adopting the casting device, the EVA film machine can produce EVA films of which the surfaces are provided with well-balanced spiral patterns, the distances between the three rolls and an extrusion die orifice can be adjusted, and the production quality of the EVA films is improved.
Description
Technical field: the utility model relates to a kind of solar energy EVA film machine, is specifically related to a kind of casting device of solar energy EVA film machine.
Background technology: EVA is the abbreviation of ethylene-vinyl acetate copolymer, and the EVA film is widely used in the pad pasting on solar panels surface.The structure of the casting device of EVA film machine is hard-wired traction frame and is drawing three rollers that are arranged side by side on the frame at present, and three rollers are the smooth smooth roll of roll surface, and wherein two is carry-over pinch rolls, and two carry-over pinch rolls are driven respectively by two motors.The same surface with common plastic film of EVA film that the EVA film machine of employing said structure is produced is smooth smooth, because the pad pasting area on solar panels surface is bigger, so in the pad pasting process on solar panels surface, in the middle of solar panels surface and EVA film, retain bubble easily, have a strong impact on the pad pasting quality; Because the traction frame fixedly installs, so the distance of roller and extrusion mould-outlet can not be regulated, this also to a certain degree influences the quality of production of EVA film in addition.
Summary of the invention: at the deficiencies in the prior art, the purpose of this utility model aims to provide a kind of casting device of solar energy EVA film machine, can help EVA film function to produce the EVA film that the surface has well-balanced screw type decorative pattern, can regulate the distance of roller and extrusion mould-outlet, improve the EVA film quality of production.
The technical solution adopted in the utility model is:
The casting device of solar energy EVA film machine, comprise traction frame and three rollers that on the traction frame, are arranged side by side, wherein two carry-over pinch rolls are by motor-driven, it is characterized in that: carry-over pinch rolls are the patterned roll that roll surface is provided with thread groove, article one, carry-over pinch rolls are the smooth smooth roll of roll surface, an other roller is resistant to elevated temperatures rubber rollers, and in the middle of patterned roll was located at, rubber rollers was slided to be located on the traction frame by slide and promoted by power cylinder.Described traction frame is installed on the elevating mechanism.
When the EVA film of the heat of extruding from EVA film machine extrusion mould-outlet is pulled the roller traction, hotting mask can be attached on the carry-over pinch rolls, because the roll surface of carry-over pinch rolls is provided with helicla flute, under the pressuring action of rubber rollers, will extrude well-balanced screw type decorative pattern on the surface of EVA film, produce the EVA film that the surface has well-balanced screw type decorative pattern, and the EVA film that the surface has a screw type decorative pattern is when carrying out pad pasting on the solar panels surface, gas in the middle of solar panels surface and the EVA film can be got rid of along the helicla flute of EVA film, and can in the middle of solar panels surface and EVA film, not retain bubble, thereby improved the pad pasting quality.In addition, the traction frame is installed in elevating mechanism and can moves up and down, and regulates the distance of roller and extrusion mould-outlet, makes the distance of roller and extrusion mould-outlet reach the optimum position, thereby improves the EVA film quality of production.
Description of drawings:
Fig. 1 is a structure chart of the present utility model.
The specific embodiment: as shown in Figure 1, the casting device of this solar energy EVA film machine, comprise traction frame 2, base plate 1 and three rollers (two carry-over pinch rolls and a resistant to elevated temperatures rubber rollers) that on traction frame 2, are arranged side by side, carry-over pinch rolls 5 are provided with the patterned roll of thread groove for roll surface, in the middle of patterned roll is located at, drive by motor 8, carry-over pinch rolls 4 are the smooth smooth roll of roll surface, drive by motor 7, rubber rollers 6 is slided to be located on the traction frame 2 by slide 3 and is promoted by hydraulic cylinder, article three, the equal design and installation in inside of roller water circulation cooling device, four footing positions of described traction frame 2 all are connected with worm gear screw mandrel lifter 10, worm gear screw mandrel lifter 10 is supported on the described base plate 1, passes through coupking shaft 11 between four worm gear screw mandrel lifters 10,12 and gear 13 be in transmission connection, worm gear screw mandrel lifter 10 is driven by motor 9.
The utility model is work like this: during machine works, program controlled motor drives the distance that instruction worm gear screw mandrel lifter is adjusted roller and extrusion mould-outlet, makes the distance of roller and extrusion mould-outlet reach the optimum position, improves the EVA film quality of production; The EVA film of the heat of extruding from EVA film machine extrusion mould-outlet is pulled roller and draws, the roller bottom of walking around rubber rollers from top, the rubber rollers outside enters the faying face of patterned roll and rubber rollers, hotting mask is attached on the patterned roll, under the pressuring action of rubber rollers, will be forced out well-balanced screw type decorative pattern on the surface of EVA film, the EVA film roller top of walking around patterned roll enters the faying face of patterned roll and smooth roll subsequently, roller bottom output from smooth roll, article three, be provided with the water cooling EGR in the roller, accelerated the cooling and shaping of EVA film.
