Description

There is the EVA film extruder of feed hydraulic regulation function
Technical field
The present invention relates to a kind of EVA film extruder, belong to the extrusion technology field of plastics.
Background technology
At present, the encapsulation of solar cell generally adopts ethene one vinyl acetate copolymer (EVA) glued membrane to be encapsulated by solar battery sheet, and is bonded together with levels protective material, forms solar module.EVA is a kind of typical random macromolecular compound, and it has good wellability when heating and melting, has good flexibility, anti-stress cracking and adhesive property during cooling curing, is a kind of ideal material that can be used for solar cell package.
What EVA film forming adopted is extrusion forming process, and whole production line generally includes mixing plant, extrusion equipment, film pressing device, trimming unit and winding device, complete batch mixing, material loading, extrude, shaping, trimming, winding process.Wherein, extrusion equipment is the major part in whole production line, is made up of extruder and the die head that is arranged at extruder end.Extruder is screw extruder, and the top of extruder is provided with hopper, and screw rod outside is provided with heater, and heated it along with the conveying of screw rod by the raw material fallen in hopper in extruder, make it plastify, molten resin goes out glued membrane through the discharging opening curtain coating of die head.The pressure roller press mold of glued membrane in film pressing device is shaping, then cooling and shaping.
Applicant finds, by hopper to extruder feed, mainly by the material self gravitation in hopper to extruder feed, feed variation is little, be not suitable for significantly changing to the function of extruder feed in the short time, do not adapt to the requirement of molten resin fluctuation.
Summary of the invention
The technical problem to be solved in the present invention is, not enough for prior art, proposes significantly to change in a kind of short time to extruder feed and adapts to the EVA film extruder with feed hydraulic regulation function of the requirement of molten resin fluctuation.
The present invention is the technical scheme solving the problems of the technologies described above proposition: a kind of EVA film extruder with feed hydraulic regulation function, comprise main barrel, be located at the extrusion screw rod in main barrel and the drive motors for driving extrusion screw rod to rotate, the feed end of described main barrel is provided with feed hopper, be made as the downward taper of the vertex of a cone bottom described feed hopper and be shaped with the opening being positioned at vertex of a cone place, the discharge end of described main barrel is provided with die head, the madial wall of described feed hopper opening part is fixed with two relative flexible sheets of semielliptical type, described die head exit place is provided with the flow sensor for generation of mass flow information, described feed hopper outside is provided with for receiving the flexible hydraulic motor of described mass flow information rear drive flexible sheet, material passing passage is formed between two flexible sheets.
The present invention adopts the beneficial effect of technique scheme to be: by being fixed with two relative flexible sheets of semielliptical type on the madial wall of feed hopper opening part, die head exit place is provided with the flow sensor for generation of mass flow information, feed hopper outside is provided with for receiving the flexible hydraulic motor of mass flow information rear drive flexible sheet, forms material passing passage between two flexible sheets; Due to give main barrel feed be EVA particle, therefore the mass flow information-driven flexible sheet that can be produced according to the flow sensor at die head exit place by hydraulic motor is stretched, and then change the size forming material passing passage between two flexible sheets, carry out feed quantity adjustment, there is in the short time advantage significantly changing to extruder feed and adapt to the requirement of molten resin fluctuation.
The improvement of technique scheme is: described die head exit place is provided with the temperature sensor for generation of temperature of charge information, and the outside border of described main barrel is provided with the heater for regulating heating-up temperature after receiving described temperature of charge information.
The improvement of technique scheme is: two flexible sheets are all shaped with 0.39mm projection.
The improvement of technique scheme is: be in series with the first analog/digital conversion module and the first central processing unit between described flow sensor and hydraulic motor.
The improvement of technique scheme is: be in series with the second analog/digital conversion module and the second central processing unit between described temperature sensor and heater.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is the structural representation that the embodiment of the present invention has the EVA film extruder of feed hydraulic regulation function.
