Abstract
The utility model relates to the technical field of thin film winding, in particular to a solar cell back film winding roller, which comprises a main body roller tube, wherein an anticorrosive layer is arranged on the roller tube, the main body roller tube is made of stainless steel, an elastic layer is arranged on the anticorrosive layer, the anticorrosive layer is made of glass fiber reinforced plastics, and the elastic layer is made of EVA rubber. When the solar cell back film winding roller is used, the use durability of the winding roller is improved through the anticorrosive layer, the contraction force generated in the back film contraction process can be buffered through the design of the elastic layer, and the occurrence of the deformation of the winding roller and the whole roll of thin films due to back film contraction after the winding is prevented.
Description
Technical field
The utility model relates to film take-up technical field, especially a kind of solar battery back film wind-up roll.
Background technology
The production of back film of solar cell is all generally flow casting molding or blow molding, although the notacoria after moulding has passed through refrigerating work procedure, but in actual production, still have certain waste heat, due to the cooling contraction of notacoria, it can produce pressure to wind-up roll, after pressure acquires a certain degree, will make wind-up roll produce distortion, and then cause entire volume notacoria volume to deform.
Utility model content
The deficiency deforming in order to overcome existing notacoria, the utility model provides a kind of solar battery back film wind-up roll.
The utility model solves the technical scheme that its technical matters adopts: a kind of solar battery back film wind-up roll, and main body roller, is provided with preservative coat above roller, and main body roller material is corrosion-resistant steel.
According to another embodiment of the present utility model, further comprise that preservative coat is provided with elastic layer.
According to another embodiment of the present utility model, further comprise that preservative coat material is glass-felt plastic.
According to another embodiment of the present utility model, further comprise that elastic layer is EVA rubber.
The beneficial effects of the utility model are, preservative coat has increased the use persistence of wind-up roll, and the design of elastic layer can cushion the convergent force producing in notacoria contraction process, prevent from because notacoria shrinks, wind-up roll and entire volume film being deformed after rolling.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. main body windings up roller, 2. preservative coat, 3. elastic layer in figure.
The specific embodiment
If Fig. 1 is structural representation of the present utility model, a kind of solar battery back film wind-up roll, comprises main body roller 1, main body roller 1 is provided with preservative coat 2 above, and main body roller material is corrosion-resistant steel, and preservative coat 2 is provided with elastic layer 3, preservative coat 2 materials are glass-felt plastic, and elastic layer 3 is EVA rubber.
The utility model is directly installed and just can be used, and preservative coat has increased the use persistence of wind-up roll, and the design of elastic layer can cushion the convergent force producing in notacoria contraction process, prevents from because notacoria shrinks, wind-up roll and entire volume film being deformed after rolling.
More than illustrate the utility model just illustrative; and it is nonrestrictive; those of ordinary skills understand; in the situation that do not depart from the spirit and scope that claims limit; can make many modifications, variation or equivalence, but all will fall in protection domain of the present utility model.
Claims (3)
