Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. In the following description, for the purpose of explanation, many specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments can also be implemented without these specific details or in the case of one or more equivalent arrangements. In addition, various exemplary embodiments can be different, but not necessarily exclusive.

Thus, features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0015] As used in this application, "upper" and "lower" refer to the upper and lower as shown in the Figure 2 accompanying drawings.

[0016] In the present application, unless otherwise clearly specified and defined, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or integrated; it can be directly connected or indirectly connected through an intermediate medium.

[0017] The embodiments of the present application provide a rapid roll temperature control device. The roll temperature control device is in fluid communication with at least one roll and can simultaneously adjust the roll temperatures of multiple rolls and independently control the temperature of each roll. As Figure 1 shown, the roll temperature control device 100 includes at least one internal circulation system 10, an external circulation system 20, and a controller (not shown in the figure).

[0018] As Figure 1 , 2As shown in Fig. 4, each roller 200 is equipped with an internal circulation system 10. The internal circulation system 10 has an inlet 1 and an outlet 2 communicating with the corresponding roller, a heater 3 and a water pump 4 arranged between the inlet 1 and the outlet 2, and a thermocouple 5 arranged at the inlet 1. The inlet 1, the water pump 4, the heater 3 and the outlet 2 are fluidly connected in sequence. The inlet 1 receives the working water in the corresponding roller 200, the outlet 2 conveys the working water to the corresponding roller 200. The water pump 4 is used to provide the conveying power for the working water conveyed in the internal circulation system 10. The heater 3 is used to heat the working water conveyed into the roller 200. The thermocouple 5 is used to detect the temperature of the working water in the corresponding roller. Among them, the heater 3, the water pump 4 and the thermocouple 5 are all signal-connected to the controller. The controller can control the start and stop of the water pump 4, receive the detection result of the thermocouple 5, and control the operation of the heater 3 according to the detection result, so that the roller surface temperature of the corresponding roller 200 can quickly reach the required working temperature.

[0019] Each internal circulation system 10 further includes a filter 6, a safety valve 7 and a pressure gauge 8. The filter 6 is fluidly connected between the inlet 1 and the water pump 4 and is used to filter the working water pumped by the water pump 4 to prevent impurities carried by the working water from entering the water pump 4 and shortening the service life of the water pump 4. The safety valve 7 is arranged between the heater 3 and the outlet 2. The pressure gauge 8 is arranged between the inlet 1 and the water pump 4 to detect the fluid pressure in the corresponding internal circulation system. Both the safety valve 7 and the pressure gauge 8 are signal-connected to the controller. The controller controls the opening and closing of the safety valve 7 according to the pressure detection result fed back by the pressure gauge 8. When the pressure gauge 8 detects that the fluid pressure in the internal circulation system exceeds the safety value, the safety valve 7 opens to release part of the pressure, ensuring the stable operation of the roller temperature control device 100.

[0020] The external circulation system 20 includes a water source (not shown in the figure) for providing cooling water and at least one angle seat valve 9. One heater 3 is configured with one angle seat valve 9. The heaters 3 of each internal circulation system are fluidly connected to the water source. The angle seat valve 9 has an open state in which the working water in the corresponding heater 3 is released to the outside of the internal circulation system 10 and a closed state in which the fluid communication between the corresponding heater 3 and the outside of the internal circulation system 10 is blocked. Among them, the heater 3 is configured to receive the cooling water from the water source when the corresponding angle seat valve 9 is in the open state. The controller can control the angle seat valve 9 to switch between the open state and the closed state. When the angle seat valve 9 is in the open state, the working water in the heater 3 is released to the outside of the internal circulation system 10, and the water pressure in the internal circulation system 10 decreases. Then, the water pressure of the cooling water in the water source that constantly enters the heater 3 is greater than the water pressure in the heater 3, and the cooling water enters the heater 3. When the angle seat valve 9 is in the closed state, the pressure in the internal circulation system 10 is stable, and the working water circulation is carried out with the roller 200, and the cooling water in the water source cannot enter the heater 3. In the embodiment of the present application, the angle seat valve 9 is a pneumatic angle seat valve.

[0021] As shown Figure 3 in FIG. 2, the heater 3 includes a tank body 31 and a plurality of heating rods 32 arranged in the tank body 31. The tank body 31 is used to contain working water so that the heating rods 32 can heat the working water. A first water inlet 311, a first water outlet 312, a second water inlet 313, and a second water outlet 314 are formed in the tank body 31; the external circulation system 20 further includes a total input port 11 connected to a water source and a total output port 12 for the working water output of the internal circulation system 10 to control the roller temperature device 100.

[0022] The first water inlet 311 is connected to the water pump 4 through a pipeline, the first water outlet 312 is connected to the outlet 2 through a pipeline, the second water inlet 313 is connected to the total input port 11 through a pipeline, the second water outlet 314 is connected to the total output port 12 through a pipeline, and an angle seat valve 9 is arranged between the second water outlet 314 and the total output port 12 to control the on-off of the fluid communication between the second water outlet 314 and the total output port 12.

[0023] The tank body 31 is a cylinder extending in the up and down direction. The first water outlet 312 and the second water outlet 314 are arranged near the upper end of the tank body 31, the second water inlet 313 and the first water inlet 311 are arranged near the lower end of the tank body 31, and the first water outlet 312, the second water outlet 314, the second water inlet 313, and the first water inlet 311 are formed in sequence from top to bottom.

[0024] As shown Figures 1-4 in FIG. 3, when the roller 200 needs to be quickly heated up, the roller temperature control device 100 performs internal circulation. The water outlet of the roller 200, the inlet 1, the water pump 4, the first water inlet 311, the first water outlet 312, the outlet 2, and the water inlet of the roller 200 are sequentially in fluid communication. The working water in the roller 200 continuously circulates into the heater 3 under the action of the water pump 4, so as to be quickly heated up and the heat is brought to the corresponding roller 200 through internal circulation, so that the roller temperature of the roller 200 is quickly increased to the corresponding temperature; when the roller 200 needs to quickly control the temperature to a certain temperature, the roller temperature control device 100 performs internal circulation and external circulation at the same time. The corresponding angle seat valve 9 is in an open state, and the internal circulation system 10 is connected to the external circulation system 20. The angle seat valve 9 enables the working water in the heater 3 to be released from the second water outlet 314. The water pump 4 continuously supplements the working water in the roller 200 into the tank body 31. The water pressure in the internal circulation system 10 decreases. The second water inlet 313 inputs cooling water into the tank body 31. The thermocouple 5 and the heating rod 32 work at the same time. When the roller 200 drops to the corresponding temperature, the angle seat valve 9 is closed, and the water source replenishes part of the cooling water until the internal circulation system 10 is filled with working water again, and the second water inlet 313 can no longer replenish the cooling water.

[0025] The internal circulation of this application is circulated by a water pump. The external circulation is always in the water inlet state. The internal circulation system and the external circulation system are connected through a heater. When rapid temperature control is required, the working water of the roller received by the heater is quickly discharged by opening the angle seat valve and cooling water is replenished at the same time, so as to cooperate with the thermocouple to achieve the effect of quickly controlling the temperature of the roller. The structure of this application is simple, the production cost is low, and the temperature of the roller can be quickly controlled.

[0026] The above shows and describes the basic principle, main features and advantages of this application. Those skilled in the art of this industry should understand that this application is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of this application. Without departing from the spirit and scope of this application, this application will have various changes and improvements.
