Abstract
The utility model discloses a pull roll of a solar EVA (Ethylene Vinyl Acetute) membrane machine, comprising a roll shaft and a roller which are connected together. The pull roll is characterized in that the cylindrical surface of the roller is provided with spiral grooves which are uniformly arranged along the cylindrical surface of the roller. By installing the solar EVA (Ethylene Vinyl Acetute) membrane machine provided by the utility model, symmetric spiral patterns can be formed on the surface of a produced EVA membrane, bubbles can be avoided generating during membrane pasting on the surface of a solar panel, and the membrane pasting quality 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 carry-over pinch rolls 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 same surface with common plastic film of EVA film that present EVA film machine 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 unavoidably, have a strong impact on the pad pasting quality.
Summary of the invention: at the deficiencies in the prior art, the purpose of this utility model aims to provide a kind of carry-over pinch rolls of solar energy EVA film machine, the EVA film that the solar energy EVA film machine of above-mentioned carry-over pinch rolls produced is installed when the pad pasting of solar panels surface, can be avoided producing bubble, improve the pad pasting quality.
The technical solution adopted in the utility model is:
The carry-over pinch rolls of solar energy EVA film machine comprise the roll shaft and the roller that connect together, and it is characterized in that: the face of cylinder of described roller is provided with helicla flute, and helicla flute is along evenly being provided with on the face of cylinder of roller.
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, the helicla flute that is provided with of the roller face of cylinder will extrude well-balanced screw type decorative pattern on EVA film surface like this, 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, improved the pad pasting quality greatly.
Description of drawings:
Fig. 1 is a structure chart of the present utility model;
Fig. 2 is the partial enlarged drawing of Fig. 1.
The specific embodiment: shown in accompanying drawing 1,2, the carry-over pinch rolls of this solar energy EVA film machine comprise the roll shaft 1 and the roller 2 that connect together, and the face of cylinder of described roller 2 is provided with helicla flute 3, and helicla flute 3 is along evenly being provided with on the face of cylinder of roller 2.
Above-mentioned carry-over pinch rolls are installed near EVA film machine extrusion mould-outlet, 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, the helicla flute that is provided with of the roller face of cylinder will extrude well-balanced screw type decorative pattern on EVA film surface like this, 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, improved the pad pasting quality greatly.
