[0029] See also Figures 1 to 3 The present application provides a temperature regulating device for regulating the temperature of a cold roller 100 and an evaporation tank 200 in a coating machine, wherein a first circulation channel is provided on the cold roller 100, and a second circulation channel is provided on the evaporation tank 200; the temperature regulating device comprises: a first cooling circuit 1 for circulating a gas medium; a temperature regulating circuit 2, wherein the temperature regulating circuit 2 is respectively connected to a medium inlet and a medium outlet of the first circulation channel; a second cooling circuit 3 for circulating a gas medium, wherein the second cooling circuit 3 is connected to the second circulation channel, and the evaporation tank 200 is cooled in the process of the gas medium in the second cooling circuit 3 flowing through the second circulation channel; a temperature return branch 4, wherein an air inlet of the temperature return branch 4 is connected to an outlet end of the second circulation channel; a first heat exchanger 5, wherein an air outlet end of the temperature regulating circuit 2, the first cooling circuit 1 and an air outlet end of the temperature return branch 4 are respectively connected to the first heat exchanger 5, and the temperature regulating medium in the temperature regulating circuit 2 performs heat exchange with a gas medium in the first cooling circuit 1 or a gas medium in the temperature return branch 4 through the first heat exchanger 5, so as to cool or return the temperature of the cold roller 100.

[0030] According to the temperature regulating device provided in the present application, it is used to regulate the temperature of the cold roller 100 and the evaporation tank 200. A first circulation channel is provided on the cold roller 100, and a second circulation channel is provided on the evaporation tank 200; wherein the temperature regulating device comprises: a first cooling circuit 1, a temperature regulating circuit 2, a second cooling circuit 3, a temperature return branch 4 and a first heat exchanger 5, wherein the first cooling circuit 1 and the second cooling circuit 3 are used to circulate the gas medium, and the temperature regulating circuit 2 is respectively connected with the medium inlet and the medium outlet of the first circulation channel; the second cooling circuit 3 is connected with the second circulation channel, and the evaporation tank 200 is cooled during the process of the gas medium in the second cooling circuit 3 flowing through the second circulation channel; the air inlet of the temperature return branch 4 is connected with the outlet end of the second circulation channel; the temperature regulating circuit 2, the air outlet end of the first cooling circuit 1 and the air outlet end of the temperature return branch 4 are respectively connected with the first heat exchanger 5, and the temperature regulating medium in the temperature regulating circuit 2 performs heat exchange with the gas medium in the first cooling circuit 1 or the gas medium in the temperature return branch 4 through the first heat exchanger 5 to cool or return the temperature of the cold roller 100. In the process of the temperature regulating loop 2 flowing through the first heat exchanger 5, heat exchange is performed with the gas medium in the first cooling loop 1, and then the temperature regulating medium in the temperature regulating loop 2 flows back to the first circulation channel to cool the cold roller 100; in the process of the gas medium in the second cooling loop 3 flowing through the second circulation channel, the evaporation tank 200 is cooled, and then the gas medium in the second cooling loop 3 flows out from the temperature return branch 4, and in the process of passing through the first heat exchanger 5, heat exchange is performed with the temperature regulating medium in the temperature regulating loop 2, and then the temperature regulating medium flows back to the first circulation channel to return the temperature of the cold roller 100. In this way, the cooling and returning-to-temperature system of the cold roller 100 is combined with the cooling system of the evaporation tank 200, and the gas medium after cooling the evaporation tank 200 is used to realize the returning-to-temperature operation of the cold roller 100, so as to achieve the purpose of recycling the gas medium and avoid the problem of energy waste.

[0031] Specifically, the temperature regulating device further includes: a first control valve 40, which is arranged between the gas medium inlet of the first heat exchanger 5 and the gas outlet end of the first cooling circuit 1 and the gas outlet end of the temperature return branch 4. The first control valve 40 is connected to the first heat exchanger 5, the first cooling circuit 1 and the temperature return branch 4 respectively. The first control valve 40 controls the first cooling circuit 1 to be connected to the first heat exchanger 5, and / or controls the temperature return branch 4 to be connected to the first heat exchanger 5. Preferably, the first control valve 40 is a three-way valve. The first control valve 40 is used to control the first cooling circuit 1 to be connected to the first heat exchanger 5 according to actual needs to achieve cooling of the cold roller 100, or to control the temperature return branch 4 to be connected to the first heat exchanger 5 to achieve temperature return of the cold roller 100.

[0032] In a specific implementation, the first heat exchanger 5 includes: a first heat exchange chamber 50, the temperature regulating circuit 2 is connected to the first heat exchange chamber 50; a first heat exchange pipeline 51 is arranged in the first heat exchange chamber 50, and the first cooling circuit 1 and the temperature return branch 4 are connected to the first heat exchange pipeline 51 through the first control valve 40. When the temperature regulating medium in the temperature regulating circuit 2 flows through the first heat exchange chamber 50, it exchanges heat with the gas medium in the first heat exchange pipeline 51, and then flows back to the first circulation channel. Preferably, the first heat exchange pipeline 51 is arranged in the first heat exchange chamber 50 in a spiral shape or along a curved trajectory, so that the heat exchange area between the gas medium and the temperature regulating medium can be increased to quickly cool down or return the temperature of the temperature regulating medium.

[0033] In the present application, the temperature regulating device further includes: a compressor 6; a return line 7, the two ends of which are respectively connected to the gas medium outlet of the first heat exchanger 5 and the air inlet of the compressor 6; an exhaust line 8, one end of which is connected to the exhaust port of the compressor 6, and the other end of which is connected to the air inlet end of the first cooling circuit 1 and / or the air inlet end of the second cooling circuit 3 through the second control valve 80. By setting up the compressor 6, the gas medium is recycled, and the return line 7 is used to reflux the gas medium after heat exchange so that it refluxes into the compressor 6.

[0034] Furthermore, the temperature regulating device further includes: a second heat exchanger 9, the second heat exchanger 9 includes a second heat exchange chamber 90 and a second heat exchange pipeline 91, the second heat exchange pipeline 91 is arranged in the second heat exchange chamber 90, the air inlet of the second heat exchange chamber 90 is connected to the exhaust port of the compressor 6, and the air outlet of the second heat exchange chamber 90 is connected to the exhaust pipeline 8; the return pipeline 7 includes: a first return section 71, the two ends of the first return section 71 are respectively connected to the air outlet of the first heat exchanger 5 and the air inlet of the second heat exchange pipeline 91; a second return section 72, the two ends of the second return section 72 are respectively connected to the air outlet of the second heat exchange pipeline 91 and the air inlet of the compressor 6. By arranging the second heat exchanger 9, the gas medium flowing out of the first return section 71 is passed into the second heat exchange pipeline 91, and then heat is exchanged with the gas medium discharged from the compressor.

[0035] The temperature regulating device further includes: a first throttle 81, which is arranged on the exhaust pipe 8 and communicated with the exhaust pipe 8, and is located between the second heat exchanger 9 and the second control valve 80; a second throttle 73, which is arranged on the first return section 71 and communicated with the first return section 71, and is located between the first heat exchanger 5 and the second heat exchanger 9; and a first pump body 74, which is arranged on the second return section 72 and communicated with the second return section 72. When cooling the cold roller 100, the temperature of the gas medium will increase after flowing through the first heat exchanger 5, and will decrease after flowing through the second throttle 73, and will be lower than the gas medium discharged from the compressor 6. Therefore, the gas medium discharged from the compressor 6 is discharged from the exhaust pipe 8 after heat exchange with the gas medium in the first return section 71. Similarly, when the cold roller 100 is warmed up, the temperature of the gas medium will decrease after passing through the first heat exchanger 5 and the second throttle 73, and then heat exchange will be performed with the gas medium discharged from the compressor 6 to cool the gas medium discharged from the compressor 6. Then, the gas medium will be further cooled when passing through the first throttle 81.

[0036] In the specific implementation process, the temperature regulating device further includes: a first temperature detection component 41, at least part of which is located in the temperature return branch 4 to detect the temperature of the gas medium in the temperature return branch 4. Preferably, the first temperature detection component 41 is a temperature detector, and in the process of cooling the evaporation tank 200, the first temperature detection component 41 feeds back the temperature signal to the controller, and if the temperature is too high, indicating that the temperature of the evaporation tank 200 is too high, the controller controls the second control valve 80 to increase the flow rate to quickly cool the evaporation tank 200; if the temperature is too low, indicating that the temperature of the evaporation tank 200 is low, the controller controls the second control valve 80 to reduce the flow rate.

[0037] In the embodiment provided in the present application, the temperature regulating circuit 2 includes: an inflow branch 20, the outlet end of the inflow branch 20 is connected to the medium inlet of the first circulation channel; an outflow branch 21, the inlet end of the outflow branch 21 is connected to the medium outlet of the first circulation channel, and the outlet end of the outflow branch 21 and the inlet end of the inflow branch 20 are respectively connected to the first heat exchanger 5. Among them, a circulation loop is formed between the first circulation channel and the inflow branch 20, the first heat exchange chamber 50 and the outflow branch 21. In the process of the temperature regulating medium passing through the first heat exchange chamber 50, after heat exchange with the gas medium in the first heat exchange pipeline 51, it flows back to the first circulation channel through the outflow branch 21. A medium storage tank 22 is also provided at the inlet end of the outflow branch 21 for storing the temperature regulating medium.

[0038] Furthermore, the temperature regulating device further comprises: a third control valve 201, which is arranged on the inflow branch 20 and communicated with the inflow branch 20, and the flow rate of the temperature regulating medium in the inflow branch 20 is controlled by the third control valve 201; a fourth control valve 210, which is arranged on the outflow branch 21 and communicated with the outflow branch 21, and the flow rate of the temperature regulating medium in the outflow branch 21 is controlled by the fourth control valve 210. The temperature regulating device further comprises: a second temperature measuring component 211, at least part of which is arranged in the outflow branch 21, and the temperature of the temperature regulating medium in the outflow branch 21 is detected by the second temperature measuring component 211; and a second pump body 212, which is arranged on the outflow branch 21 and communicated with the outflow branch 21. The temperature of the temperature regulating medium is detected by the second temperature measuring component 211. When the temperature of the temperature regulating medium is too high, the temperature of the surface cold roller 100 is too high. At this time, the flow in the inflow branch 20 and the outflow branch 21 is increased through the third control valve 201 and the fourth control valve 210 to quickly cool the cold roller 100. When the temperature of the cold roller 100 reaches room temperature, the third control valve 201 and the fourth control valve 210 are closed to avoid continuous heating or cooling of the cold roller 100. The second pump body 212 provides power to the temperature regulating medium in the outflow branch 21, so that it passes quickly and flows from the outflow branch 21 into the first circulation channel.

[0039] Preferably, a gas storage tank is also provided between the air inlet of the compressor 6 and the first pump body 74 for storing the gas medium. The gas medium is cooled by the second throttle 73 and then enters the second heat exchanger 9 to cool the high-pressure gas discharged from the compressor. The gas flowing out of the second heat exchanger 9 returns to the gas storage tank.

[0040] After the coating is completed, during the temperature recovery process, the low-temperature gas medium flows through the evaporation tank 200 through the second control valve 80 (the evaporation tank is used to accommodate the heating electrode, and the heating electrode has a plurality of holes. The holes are used to accommodate the crucible, and the crucible contains the evaporation material. After the electrode is heated, the crucible is heated to evaporate the evaporation material), and the electrode heating system is cooled down. After the low-temperature gas flows through the evaporation tank, the temperature will increase due to heat exchange, and then the gas medium with increased temperature enters the first heat exchanger 5 through the first control valve 40 to recover the temperature of the cold drum.

[0041] The evaporation tank is provided with a third temperature detection component for detecting the temperature of the evaporation tank. When the temperature of the evaporation tank drops to the set temperature, the cooling stops. Because the evaporation tank at more than 1000 degrees is cooled, the cold roller must have been warmed up after the evaporation tank is cooled to the required temperature. Therefore, there will be no situation where "the evaporation tank has been cooled to the required temperature, but the cold roller has not been fully warmed up".

[0042] In the utility model, the gas medium adopts carbon dioxide or ammonia.

[0043] From the above description, it can be seen that the above embodiments of the present application achieve the following technical effects:

In the process of the temperature regulating loop 2 flowing through the first heat exchanger 5, heat exchange is performed with the gas medium in the first cooling loop 1, and then the temperature regulating medium in the temperature regulating loop 2 flows back to the first circulation channel to cool the cold roller 100; in the process of the gas medium in the second cooling loop 3 flowing through the second circulation channel, the evaporation tank 200 is cooled, and then the gas medium in the second cooling loop 3 flows out from the temperature return branch 4, and in the process of passing through the first heat exchanger 5, heat exchange is performed with the temperature regulating medium in the temperature regulating loop 2, and then the temperature regulating medium flows back to the first circulation channel to return the temperature of the cold roller 100. In this way, the cooling and returning-to-temperature system of the cold roller 100 is combined with the cooling system of the evaporation tank 200, and the gas medium after cooling the evaporation tank 200 is used to realize the returning-to-temperature operation of the cold roller 100, so as to achieve the purpose of recycling the gas medium and avoid the problem of energy waste.
