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 not identical yet in the strand simultaneously, arrange 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, having 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 winding device, finishes batch mixing, material loading, extrudes, moulding, side cut, winding process.Wherein, extrusion equipment is the major part in the whole production line, consisted of by extruder and the die head that is arranged at the extruder end, extruder is single screw extrusion machine, the top of extruder is provided with hopper, and the screw rod outside is provided with heater, will fall in the hopper raw material in the extruder along with the conveying of screw rod to its heating, make its plasticizing, molten resin goes out glued membrane through the discharging opening curtain coating of die head.The pressure roller press mold moulding of glued membrane in film pressing device, then cooling and shaping.
Outside extruder screw, be arranged with the temperature control water chamber, be connected with heat exchanger through circulating water pipe, heat exchanger is connected with temperature control water tank by water pipe, when main-machine screw is overheated, be main-machine screw cooling by the recirculated water in the temperature control water chamber, and when main-machine screw when just opening, water circulation system can provide preheating, therefore the recirculated water in the temperature control water chamber is generally warm water, adopts at present electrical bar to heat storing water in the water tank, needs Artificial Control, temperature is closed heating after reaching rated value, when the storage coolant-temperature gage is too high in the water tank (by the high temperature reflux water of heat exchanger discharge), need to open water pipe, replenish cold water.On the one hand, control loaded down with trivial details, labor intensive; On the other hand, temperature control can not reach constant temperature not, affects the stability of main-machine screw processing temperature.
Summary of the invention
For the technical problem of above-mentioned existence, the purpose of this utility model is: proposed a kind of temperature control water circulatory system of EVA glued membrane extruder, improved automation mechanized operation, guaranteed the constant of recirculated water water temperature.
Technical solution of the present utility model is achieved in that a kind of temperature control water circulatory system of EVA glued membrane extruder, comprise the circulating water cavity that is arranged at the main-machine screw outside, with circulating water pipe, the heat exchanger that is connected with circulating water pipe and the temperature control water tank of this circulating water cavity connection, be provided with heating rod and water supplement port in this temperature control water tank, described water supplement port is connected with running water pipe through filling pipe, described filling pipe is provided with a magnetic valve, described heating rod is provided with an electromagnetic switch, and the control end of described magnetic valve and electromagnetic switch is connected with console controller respectively.
In the technique scheme, nominal operation time and the blanking time of prestore in the described console controller heating and moisturizing, the moisturizing of time opening magnetic valve or the heating of unlatching electromagnetic switch guarantee that the water temperature in the temperature control water tank is constant in a segment limit.
In the technique scheme, be provided with temperature sensor in the described temperature control water tank, the signal output part of this temperature sensor is connected with described console controller.By the water temperature in the temperature sensor the real time measure temperature control water tank, and send the data to console controller, according to the rated temperature value that prestores in the console controller, judge to open and close heating rod or water supplement port.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
1, owing at filling pipe magnetic valve being set in the utility model, at heating rod electromagnetic switch is set, by keying and the working time of console controller control magnetic valve and electromagnetic switch, thereby the circulating water temperature in the assurance temperature control water tank keeps within the specific limits, guarantees the stability of main-machine screw processing temperature;
2, set temperature sensor in temperature control water tank detects the recirculated water water temperature in the temperature control water tank in real time, makes console controller can better control water temperature, and water temperature is constant on rated value, need not manpower intervention, controls more convenient.
