As shown in Figure 1, the EVA film casting machine roller cooling device of the utility model preferred embodiment, comprise blower fan 11 for air amount, for the casting machine 4 of moulding EVA film, and be connected between blower fan 11 and casting machine 4 for air being carried out to the cooling driers 9 of cooling and dewatering; Between described blower fan 11, cooling driers 9, casting machine 4, by air-cooled pipeline, connect, in described casting machine, be provided with for air-cooled pipeline and the described casting machine of air and EVA film heat-shift are also provided with for discharging the exhaust outlet 16 of the air after heat absorption.
Described casting machine 4 comprises casting machine roller, for moulding EVA film.
In figure, blower fan 11 is conveyed into pipeline by the air in environment, and enter cooling driers 9 by pipeline, after the cooling and dewatering through cooling driers 9, form as the low temperature of low-temperature receiver, low humid air, this low-temperature receiver gas is through pipeline flow-direction casting machine roller, and controls it and enter the flow of casting machine roller by being arranged on valve 5,6,7 in casting machine roller air-cooled pipeline; When the gas to after casting machine roller cooling heat absorption directly drains in external environment by the exhaust outlet on air-cooled pipeline.
9 pairs of air of described cooling driers carry out cool-down dehumidification processing; Described cooling driers is not established pre-cooler, by compressor, and condenser, expansion valve, the equipment such as evaporimeter and moisture trap form, and described compressor, condenser, expansion valve, evaporimeter and moisture trap are connected successively; Described compressor is also connected with evaporimeter; Described evaporimeter is provided with an air inlet port and the port of giving vent to anger, and air, from described air inlet port enters evaporimeter cooling, flows out from the port of giving vent to anger, and enters moisture trap; Described moisture trap is connected with casting machine through air-cooled pipeline.Cooling driers 9 adopts the operation principle of cooling dewfall, compressed air is dried to cooling.Described compressor will be sent into condenser after refrigerant compression, and condenser absorbs the heat of refrigerant, makes refrigerant become liquid from gas, then through expansion valve step-down, enters evaporator evaporation heat absorption, then sends the refrigerant after heat absorption back to compressor.At refrigerant, enter evaporimeter simultaneously, blower fan air amount carries out heat exchange by evaporimeter and refrigerant, becomes cold air and through air-cooled pipeline, flow to casting machine roller again after moisture trap is removed moisture.
Described casting machine roller comprises rubber roll 1, flower roller 2 and chill roll 3; Described casting machine roller comprises for the rubber roll 1 of moulding EVA film and flower roller 2, chill roll 3 for cooling EVA film, one end of described rubber roll 1, flower roller 2, chill roll 3 is connected to cooling driers 9 by air-cooled pipeline, and the other end of rubber roll 1, flower roller 2, chill roll 3 is connected to exhaust outlet by air-cooled pipeline.Flower roller 2, under the cooperation with rubber roll 1, can suppress according to different product demands corresponding decorative pattern in EVA casting films, through flower roller 2 and rubber roll 1 compressing after EVA casting films again by chill roll 3 sizing of lowering the temperature.The low temperature and low humidity gas of cooling driers output is carried toward casting machine roller place by pipeline, valve 5,6,7 is arranged in the air-cooled pipeline of casting machine roller, regulate respectively the gas flow entering in casting machine rubber roll 1, flower roller 2 and chill roll 3, to meet different cooling demands; The low temperature and low humidity air that enters casting machine roller is reached for the effect of casting machine roller cooling by heat exchange.Air heat absorption after effect heats up, and owing to being subject to other, does not pollute, and does not need further processing to be disposed in external environment.Valve 10 is arranged on the air-cooled pipeline between blower fan 11 and cooling driers 9, for regulating the gas flow that enters cooling driers 9 by blower fan 11, valve 8 is arranged on the air-cooled pipeline between casting machine 4 and cooling driers 9, for regulating the gas flow that enters casting machine 4 by cooling driers 9, to meet different cooling demands.
In addition, after employing air cooling, for strengthening cooling effect, heat exchange fin is installed in the shell of described casting machine roller, Fig. 2 is the heat exchange fin sectional view in chill roll.Described heat exchange fin is located in chill roll, is understandable that, in flower roller and rubber roll, equally heat exchange fin can be set, and makes the cooling effect of EVA film better.As shown in Figure 2, described heat exchange fin comprises fin support 14 and several fin 12, and described several fins 12 are uniformly distributed between fin support 14 and casting machine roller shell 13 and around described fin support 14.Described fin support the 14 axial settings along described casting machine roller shell and with described casting machine roller shell concentric, described fin supports the radial dimension that 14 radial dimension is less than described casting machine roller shell.By the setting of described heat exchange fin, make EVA film on casting machine roller pass through casting machine roller, better with the heat transfer effect that passes through the air in casting machine roller, thus make the cooling effect of EVA film on casting machine roller better.Certain space need to be left in the two ends of casting machine roller simultaneously---equal air chamber 15, so that air can evenly pass through fin space.This chamber space size can omit inching as required.Fin can be copper sheet or stainless steel substrates.
Consult Fig. 1, when the EVA film casting machine roller cooling device of the utility model preferred embodiment is worked, blower fan 11 is conveyed into air-cooled pipeline by the air in environment, described air obtains cool-down dehumidification and processes when through cooling driers, the air of processing through cool-down dehumidification enters in casting machine through air-cooled pipeline, in casting machine with casting machine roller on the heat of EVA film exchange, thereby cooling EVA film, and the hot-air heating up after heat-shift is discharged by exhaust outlet.
In sum, the utility model selects the EVA film casting machine roller cooling device of embodiment to pass through the cooling EVA film of air compared to adopting cooling water, can eliminate cooling water risk of leakage, and by cooling driers is set, reduce workshop dehumidifier power consumption, this cooling device is simple in structure in addition, can Maintenance and Repair expense, be conducive to energy-conservation.
The foregoing is only preferred embodiment of the present utility model, and need not one restriction the utility model, all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
