Technical field
The present invention relates to a kind of EVA glued membrane production system, the conveying equipment in particularly a kind of EVA glued membrane production system after the glued membrane curtain coating.
Background technology
Solar cell is if directly be exposed in the air, and its photoelectric transformation efficiency can descend very soon, loses practical value.Therefore, the research and development of the encapsulation material of solar cell are just very important.For reaching the purpose that is isolated from the outside; Adopt transparent, light aging resisting, adhesive property good, can bear that atmosphere changes and rubber-like ethylene-vinyl acetate copolymer (EVA) glued membrane is sealed solar battery sheet; And be bonded together with the levels protective material, constitute solar module.
EVA is a kind of typical random macromolecular compound; In its molecular structure; The irregular arrangement of substituting group on strand, the configuration of asymmetric carbon atom is also inequality in the strand simultaneously, arranges also irregular; Therefore it be that a kind of crystallinity is less, polarity and the higher material of pliability; It has good wellability when heating and melting in addition, has good flexibility, anti-stress cracking and adhesive property during cooling curing, is a kind of comparatively desirable material that can be used for solar cell package.
What the EVA film forming adopted is extrusion forming process, and whole production line generally includes mixing plant, extrusion equipment, film pressing device, side cut unit and retractable volume equipment, accomplishes batch mixing, material loading, extrudes, rolls, side cut, winding process.Will have of decision end product quality: raw material and prescription; The hot melt expressing technique reaches casting molding processes and controls several aspects, and in the casting molding processes process; Environment temperature and humidity also is an important step; Suitable humidity and stable temperature, the Shen of drawing that can reduce film is out of shape the tension force of controlling diaphragm.
At present, the control standardized degree of temperature and humidity is not enough in the EVA production process, and most of producers adopt central air conditioner system to accomplish temperature controlling; Control to humidity also is the auxiliary dehumidification principle solve problem that adopts under the air-conditioning system refrigeration mode; And central air-conditioning only remains on the normal temperature state with the temperature in the workshop, is generally about 22 ℃～24 ℃, concerning from the EVA glued membrane of high temperature (usually about 100 ℃) curtain coating output; Can not cool off rapidly; In addition, the EVA glued membrane is to carry through being arranged in the transmission crawler belt that is closed in production line, therefore; Film temperature more is not subject to be positioned at the central air-conditioning in workshop and controls, and directly has influence on the quality of finished product glued membrane.
Summary of the invention
Technical problem to above-mentioned existence; The objective of the invention is: proposed the conveying equipment after the glued membrane curtain coating in a kind of EVA glued membrane production system, environment temperature and humidity in the control course of conveying shorten cool time; Reduce and draw the Shen distortion, guarantee finished product EVA glued membrane quality.
Technical solution of the present invention is achieved in that the conveying equipment after the glued membrane curtain coating in a kind of EVA glued membrane production system; The conveyor frame that comprises sealing; Be arranged at the transmission crawler belt in the conveyor frame and drive the motor of this transmissions crawler belt, an end of said conveyor frame be nearly calibrator advance the film mouth, the other end is the film outlet port that closely unreels the unit; In the said conveyor frame, be positioned at into that film mouth place is provided with a Water cooled air conditioners; Said Water cooled air conditioners is positioned at the top of said transmission crawler belt, and air outlet is towards said membrane oral-lateral, and the top of said conveyor frame is fixed at said Water cooled air conditioners top through installing rack.
In the technique scheme, said installing rack is made up of the connecting rod and the hold-down screw that are positioned at said Water cooled air conditioners two ends, and said connecting rod is fixedly connected with the top cross beam of said conveyor frame, and said Water cooled air conditioners top is fixed through hold-down screw and said connecting rod.
In the technique scheme, said conveyor frame is a body structure, on the body structure side plate of corresponding said Water cooled air conditioners circulating water pipe side, offers installing hole, and said circulating water pipe is connected with outside filling pipe, backflow water pipe through installing hole.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
1, the film mouth place of advancing in conveyor frame is provided with Water cooled air conditioners among the present invention; Can be the high temperature EVA glued membrane cooling cooling in the entering conveyor frame rapidly through the temperature of control Water cooled air conditioners; Help the moulding of EVA glued membrane, reduce and draw the Shen metaboly to take place, guarantee the quality of EVA glued membrane finished product;
2, use the Water cooled air conditioners cooling, control the temperature in the conveyor frame on the one hand, simultaneously, Water cooled air conditioners can also be regulated humidity, for the EVA glued membrane provides good transmission environment.
