Description
Technical field
The present invention relates to a kind of glued membrane destressing device, belong to the field shaping technique of plastics。
Background technology
At present, the encapsulation of solaode be generally adopted ethylene one vinyl acetate copolymer (EVA) glued membrane by solar battery sheet encapsulate, and with up and down respectively layer protection material be bonded together, constitute solar module。EVA is a kind of typical random macromolecular compound, and it has good wellability when adding heat fusing, has good flexibility, anti-stress cracking and adhesive property, be a kind of ideal material that can be used for solar cell package during cooling curing。
The production process that EVA film forming adopts is: from the EVA film of extruder die head extrusion, and it needs to carry out the transmission of relatively long distance through too much group transfer roller, makes EVA film cool off and shapes, after finally carrying out rolling in transmission process。
It has been found that the EVA film sheet applied for photovoltaic cell encapsulation etc., percent thermal shrinkage is an important index, and percent thermal shrinkage is more low more favourable for application such as postorder photovoltaic cell encapsulation。But, existing equipment carries out tempering destressing after EVA film is shaped and carries out eliminating stress, reduce thermal contraction, but the global quality control for EVA film sheet is bad, it is impossible to while EVA film is carried out percent thermal shrinkage control, carry out the control of the indexs such as EVA film planarization。
Summary of the invention
The technical problem to be solved in the present invention is, not enough for prior art, it is proposed to a kind of simple in construction and uniformly can effectively reduce the EVA adhesive film destressing device of EVA adhesive film percent thermal shrinkage。
The present invention solves that the technical scheme that above-mentioned technical problem proposes is: a kind of EVA adhesive film destressing device, including the infrared heating pipe being located at below extruder die head and concave mirror, axially extending along infrared heating pipe of described concave mirror, described concave mirror is located at the diaphragm side place of the outlet lower section of extruder die head, and described infrared heating pipe is located on concave mirror focal length。
The present invention adopts technique scheme to provide the benefit that: by being located at below extruder die head by infrared heating pipe and concave mirror, axially extending along infrared heating pipe of concave mirror, concave mirror is located at the diaphragm side place of the outlet lower section of extruder die head, and infrared heating pipe is located on concave mirror focal length；Heated by infrared heating pipe, it is possible to effectively reducing EVA adhesive film percent thermal shrinkage, infrared light infrared heating pipe sent by concave mirror is uniformly exported after reflecting, it is possible to uniform reduction EVA adhesive film percent thermal shrinkage, overall structure is simple。
The improvement of technique scheme is: described infrared heating pipe is the infrared heating pipe of three settings side by side up and down, and described concave mirror is the concave mirror of three settings side by side up and down, and each infrared heating pipe is located on a concave mirror focal length。
The improvement of technique scheme is: described infrared heating pipe is the twin pipe infrared radiator of medium wave。
The improvement of technique scheme is: the two ends of described concave mirror is provided with reflecting mirror plug。
The present invention adopts technique scheme to provide the benefit that: be provided with reflecting mirror plug by the two ends of concave mirror, and infrared ray infrared heating pipe sent further reflexes in EVA adhesive film, improves efficiency。
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is the structural representation of embodiment of the present invention EVA adhesive film destressing device。
