[0028] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and should not be used to limit the present application.
[0029] It should be noted that although the functional modules are divided in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described can be performed in a manner different from the module division in the device or the order in the flowchart. The terms "first", "second", etc. in the specification and the above drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence.
[0030] The flowchart shown in the drawings is only an exemplary illustration, and does not necessarily include all contents and operations / steps, nor does it necessarily be executed in the order described. For example, some operations / steps can be further divided, and some operations / steps can be combined or partially combined, so the actual execution order may be changed according to the actual situation.
[0031] It should be understood that the above description refers to Figure 1 As shown in FIG. 4, the cooling system comprises:
[0032] The cooling roller assembly comprises an outer roller 110, an inner roller 120, a main guide plate 121, and two flow channel control devices. The outer roller 110 is sleeved on the inner roller 120. The main guide plate 121 is used to separate the area between the adjacent two side walls of the outer roller 110 and the inner roller 120 to form first and second spiral flow channels 131 and 132 with opposite flow directions. The two flow channel control devices are respectively arranged corresponding to the first and second spiral flow channels 131 and 132.
[0033] The detection assembly is provided with at least one group, and each group of detection assemblies comprises two detection pieces 210. The two detection pieces 210 of the same group are respectively arranged corresponding to the first and second spiral flow channels 131 and 132.
[0034] The control module is used to adjust the opening degree of the flow channel control device according to the flow channel data detected by each group of detection assemblies to adjust the liquid inlet pressure of the target spiral flow channel, which includes the first spiral flow channel 131 and / or the second spiral flow channel 132.
[0035] Therefore, by setting the at least two first spiral flow channels 131 and the second spiral flow channels 132 with opposite flow directions, the cooling medium can be cross-flowed between the outer roller barrel 110 and the inner roller barrel 120 of the cooling roller, so as to reduce the temperature difference on both sides of the cooling roller, and by setting the detection assembly to monitor the flow channel data of the first spiral flow channels 131 and the second spiral flow channels 132 with opposite flow directions, and by controlling the flow channel control device through the control module to realize intelligent control of the cooling medium of the first spiral flow channels 131 and the second spiral flow channels 132 with opposite flow directions, the temperature distribution on both sides of the cooling roller is further made more uniform. Therefore, compared with the related art, the embodiment of the present application can reduce the temperature difference on both sides of the outer roller barrel 110 of the cooling roller.
[0036] It should be noted that, in some embodiments, referring to Figures 1 to 8 It should be noted that, in some embodiments, referring to Figure 1 It should be noted that, in some embodiments, referring to It should be noted that, in some embodiments, referring to
[0037] It should be noted that, in some embodiments, referring to Figure 2 It should be noted that, in some embodiments, referring to It should be noted that, in some embodiments, referring to
[0038] It should be noted that, in some embodiments, referring to Figure 1 It should be noted that, in some embodiments, referring to Figure 2As shown, the cooling medium is water as an example, the water feeding roller 150 and the central water pipe 140 are coaxially arranged in the inner roller 120 in sequence, the water outlet channel 122 is formed between the water feeding roller 150 and the central water pipe 140, the inlet end of the water outlet channel 122 and the inlet end of the central water pipe 140 are located at the left side of the inner roller 120, the outlet end of the central water pipe 140 is communicated with the second liquid inlet 1321 of the second spiral channel 132, the second liquid outlet 1322 of the second spiral channel 132 is communicated with the inlet end of the water outlet channel 122, and the outlet end of the water outlet channel 122 and the first liquid outlet 1312 of the first spiral channel 131 are located at the right end of the inner roller 120; the flanges of the inner roller 120 and the outer roller 110 near the inlet end of the central water pipe 140 form a water inlet cavity, and the water inlet cavity is communicated with the first liquid inlet 1311 of the first spiral channel 131. At this time, for the first spiral channel 131, water enters the first spiral channel 131 from the water inlet cavity and flows out from the right side of the inner roller 120, and for the second spiral channel 132, water enters from the inlet end of the central water pipe 140, flows through the second spiral channel 132, and then reversely flows through the water outlet channel 122 to the right side of the inner roller 120; thereby realizing unified water inlet at the left side of the cooling roller and unified water outlet at the right side of the cooling roller. In some embodiments, the water feeding roller 150 is provided with a sandwich layer, and the side wall of the sandwich layer and the central water pipe 140 form the water outlet channel 122, so as to reduce the influence of the heat of the water outlet channel 122 on the first spiral channel 131 and the second spiral channel 132 through the sandwich layer. In some embodiments, a heat insulation plate 153 is further arranged between the water outlet channel 122 and the central water pipe 140, so as to block the heat of the water outlet channel 122 from spreading to the central water pipe 140.
[0039] It should be noted that in some embodiments, other flow guide plates are also provided to further separate the area between the outer roller 110 and the inner roller 120 to obtain other spiral channels for convection. At this time, the processing of the spiral channel is referred to the first spiral channel 131 and the second spiral channel 132 with the same flow direction.
[0040] It should be noted that the flow channel control device is used to control the liquid inlet pressure of the corresponding spiral channel, so that the temperature difference on both sides of the outer roller 110 can be controlled by adjusting the liquid inlet pressure. Taking water as the cooling medium, the flow channel control device is used to control the water inlet pressure of the first spiral channel 131 and the second spiral channel 132. In some embodiments, the flow channel control device is an electronic valve, and the liquid inlet pressure control is realized by adjusting the opening degree of the electronic valve. The adjustment of the liquid inlet pressure will affect the speed of the flow in the flow channel and thus affect the heat dissipation efficiency, therefore, the temperature difference control can be realized by controlling the flow channel control device.
[0041] It should be noted that the detection member 210 is used to detect the flow channel data corresponding to the flow direction. In some embodiments, the flow channel data is temperature, and in other embodiments, the flow channel data is flow rate, etc.
[0042] It should be noted that the control module can be set as a PLC chip and arranged on the cooling roller. In other embodiments, the control module can be a terminal device. The present application does not limit this, and those skilled in the art can set it according to actual needs.
[0043] It should be noted that by setting the cross-counterflow spiral flow channel, the temperature difference of the outer roller cylinder 110 at the same cross-sectional position is smaller than that of the cooling roller with only a single-direction flow channel. At this time, the real-time control of the control module can further reduce the temperature difference of the two sides of the outer roller cylinder 110.
[0044] It can be understood that the control module is used to:
[0045] Receive the flow channel data of the same group of detection members 210 within a preset time period;
[0046] Input the flow channel data into a preset self-adjusting model to obtain pressure adjustment data; wherein the pressure adjustment data includes opening data of the flow channel control device to be adjusted;
[0047] Adjust the flow channel control device to be adjusted according to the pressure adjustment data, so as to adjust the liquid inlet pressure of the target spiral flow channel corresponding to the flow channel control device to be adjusted.
[0048] It should be noted that the opening data is used to represent the adjustment mode of the flow channel control device, such as the adjustment direction being to increase or decrease, or how much to increase or decrease.
[0049] It should be noted that the preset time period can be set according to actual needs, so that the obtained flow channel data can better reflect the cooling state of the cooling roller, thereby reducing the probability of over-adjustment.
[0050] It should be noted that the flow channel data corresponds to the detection member 210 one by one. Each detection member 210 can obtain the flow channel data on the flow channel at the position within the preset time period. When the detection assembly is provided with multiple groups, the flow channel data of each detection member 210 in the multiple detection assemblies is input into the self-adjusting model. For example, the detection member 210 is located on the first spiral flow channel 131, and the flow channel data on the first spiral flow channel 131 is obtained. For example, the detection member is located on the second spiral flow channel 132, and the flow channel data on the second spiral flow channel 132 is obtained.
[0051] It can be understood that, as shown in Figure 5 The detection assembly is provided with multiple groups, and the self-adjusting model performs the following steps:
[0052] According to the flow channel data, a first temperature difference value of the same group of detection components 210 is obtained;
[0053] When the first temperature difference value exceeds a first threshold value, a flow channel control device to be adjusted is determined, and first opening degree data of the flow channel control device to be adjusted is determined;
[0054] According to the flow channel data, a second temperature difference value and a temperature range of each detection component 210 in the same flow direction are obtained;
[0055] When one of the second temperature difference value and the temperature range does not meet a preset requirement, a flow channel control device corresponding to the second temperature difference value is determined as the flow channel control device to be adjusted, and first opening degree data of the flow channel control device to be adjusted is determined according to the second temperature difference value and the temperature range;
[0056] According to the first opening degree data, second opening degree data of another flow channel control device is determined;
[0057] According to the first opening degree data and the second opening degree data, pressure adjustment data is determined.
[0058] It should be noted that the first opening degree data represents the opening degree data of the flow channel control device to be adjusted determined according to the flow channel data, and the second opening degree data represents the opening degree data of another flow channel control device determined based on the opening degree of the flow channel control device to be adjusted. In some embodiments, only the first opening degree data is calculated, and the pressure adjustment data is composed of the first opening degree data. In other embodiments, the first opening degree data and the second opening degree data are calculated, and the pressure adjustment data is composed of the first opening degree data and the second opening degree data.
[0059] It should be noted that not meeting the preset requirement means that the second temperature difference value exceeds a second threshold value, or the temperature range is not within a preset temperature range.
[0060] For example, with reference to Figure 3As shown, assuming that the first temperature difference of the first spiral flow channel 131 is within the first threshold value, and the second temperature difference of the second spiral flow channel 132 exceeds the second threshold value, the flow channel control device corresponding to the second spiral flow channel 132 is the flow channel control device to be adjusted, at this time, the first opening degree data of the second spiral flow channel 132 can be obtained. According to the first opening degree data of the second spiral flow channel 132, it is determined whether the first spiral flow channel 131 needs to be adjusted, when the first spiral flow channel 131 needs to be adjusted, the second opening degree data of the first spiral flow channel 131 is generated, at this time, the pressure adjustment data includes the first opening degree data of the second spiral flow channel 132 and the second opening degree data of the first spiral flow channel 131. For example, as shown, assuming that the first temperature difference of the first spiral flow channel 131 and the second spiral flow channel 132 both exceeds the first threshold value, the flow channel control device corresponding to the first spiral flow channel 131 and the second spiral flow channel 132 is the flow channel control device to be adjusted, at this time, the first opening degree data of the first spiral flow channel 131 and the second spiral flow channel 132 will be generated, at this time, if the second temperature difference or the temperature range of the first spiral flow channel 131 does not meet the requirements, the first opening degree data of the first spiral flow channel 131 will be re-determined, and the second opening degree data of the second spiral flow channel 132 will be re-determined according to the first opening degree data of the first spiral flow channel 131 and the first opening degree data of the second spiral flow channel 132, at this time, the pressure adjustment data is determined based on the first opening degree data of the first spiral flow channel 131 and the second opening degree data of the second spiral flow channel 132 obtained above. For example, as shown, assuming that the first temperature difference of the second spiral flow channel 132 exceeds the first threshold value, the second spiral flow channel 132 is the flow channel control device to be adjusted, at this time, the first opening degree data of the second spiral flow channel 132 will be generated, at this time, if the second temperature difference or the temperature range of the first spiral flow channel 131 meets the requirements, the first opening degree data of the first spiral flow channel 131 will be determined, and the second opening degree data of the second spiral flow channel 132 will be determined according to the first opening degree data of the first spiral flow channel 131, at this time, in some embodiments, the second spiral flow channel 132 has the first opening degree data and the second opening degree data, the first spiral flow channel 131 has the first opening degree data, at this time, the pressure adjustment data is composed of the first opening degree data of the first spiral flow channel 131, the first opening degree data and the second opening degree data of the second spiral flow channel 132. In other embodiments, when the second temperature difference or the temperature range of the first spiral flow channel 131 meets the requirements, the second opening degree data is determined according to the first opening degree data of the first spiral flow channel 131 and the first opening degree data of the second spiral flow channel 132, at this time, the pressure adjustment data is composed of the first opening degree data of the first spiral flow channel 131 and the second opening degree data of the second spiral flow channel 132.
[0061] It should be noted that the first temperature difference represents the difference between the temperatures detected by the two detection members 210 of the same group. For example, taking water as the cooling medium, and taking the temperature sensor as the detection member 210, it is assumed that the first temperature difference of the first spiral flow channel 131 exceeds the first threshold value, and the second temperature difference of the second spiral flow channel 132 exceeds the second threshold value, at this time, the flow channel control device corresponding to the first spiral flow channel 131 is the flow channel control device to be adjusted, at this time, the first opening degree data of the first spiral flow channel 131 will be generated, at this time, if the second temperature difference or the temperature range of the second spiral flow channel 132 meets the requirements, the first opening degree data of the second spiral flow channel 132 will be determined, and the second opening degree data of the first spiral flow channel 131 will be determined according to the first opening degree data of the second spiral flow channel 132, at this time, in some embodiments, the first spiral flow channel 131 has the first opening degree data and the second opening degree data, the second spiral flow channel 132 has the first opening degree data, at this time, the pressure adjustment data is composed of the first opening degree data of the first spiral flow channel 131, the first opening degree data and the second opening degree data of the second spiral flow channel 132. In other embodiments, when the second temperature difference or the temperature range of the second spiral flow channel 132 meets the requirements, the second opening degree data is determined according to the first opening degree data of the second spiral flow channel 132, at this time, the pressure adjustment data is composed of the first opening degree data of the first spiral flow channel 131 and the second opening degree data of the second spiral flow channel 132.Figures 2 to 6 As shown, the first spiral flow channel 131 flows from left to right, and the second spiral flow channel 132 flows from right to left. There are three temperature sensors in each of the first spiral flow channel 131 and the second spiral flow channel 132. Figure 6 As shown, the temperature sensors in the same region are grouped in pairs, and each pair of temperature sensors detects a corresponding temperature. The first temperature difference is the difference between the temperatures detected by the two temperature sensors in the same group. The first temperature difference between each group of the first spiral flow channel 131 and the second spiral flow channel 132 is determined. If the difference is too large, the pressure of the inlet of the flow channel is increased or decreased to reduce the temperature difference. For the first spiral flow channel 131, the second temperature difference between the three temperature sensors is determined based on the temperature values of the three temperature sensors in the first spiral flow channel 131. If the difference is too large or the temperature is not within the allowed range, the pressure of the inlet of the first spiral flow channel 131 is changed. The water pressure of the second spiral flow channel 132 is adjusted based on the pressure difference between the first spiral flow channel 131 and the second spiral flow channel 132 to form a dynamic circulation control of the water pressure. For the second spiral flow channel 132, the second temperature difference between the three temperature sensors is determined based on the temperature values of the three temperature sensors in the second spiral flow channel 132. If the difference is too large or the temperature is not within the allowed range, the water pressure of the second spiral flow channel 132 is changed. The water pressure of the first spiral flow channel 131 is adjusted based on the water pressure difference between the first spiral flow channel 131 and the second spiral flow channel 132.
[0062] It can be understood that, referring to Figure 2 and Figure 7 As shown, the cooling roller assembly further includes a water delivery roller 150 arranged in the inner roller 120, and an auxiliary flow channel corresponding to the first spiral flow channel 131 and the second spiral flow channel 132 is arranged between the water delivery roller 150 and the inner roller 120. A water distribution plate 124 and a liquid inlet 123 are arranged in the first spiral flow channel 131 and the second spiral flow channel 132. The water distribution plate 124 on the first spiral flow channel 131 is used to deliver the cooling medium entering the first inlet 1311 of the first spiral flow channel 131 into the corresponding auxiliary flow channel according to a predetermined proportion. The water distribution plate 124 on the second spiral flow channel 132 is used to deliver the cooling medium entering the second inlet 1321 of the second spiral flow channel 132 into the corresponding auxiliary flow channel according to a predetermined proportion. The cooling medium in the first spiral flow channel 131 and the second spiral flow channel 132 flows into the corresponding auxiliary flow channel through the liquid inlet 123.
[0063] It should be noted that, by way of example, referring to Figure 1 and Figure 2As shown, the water distribution plate 124 divides the space corresponding to the flow channel according to a preset ratio, and the space in the lower part is provided with a third liquid inlet 155. At this time, the cooling medium in the lower part enters the corresponding auxiliary flow channel from the third liquid inlet 155, and the cooling medium in the upper part continues to be transported in the corresponding flow channel.
[0064] It should be noted that the auxiliary flow channel corresponding to the first spiral flow channel 131 and the second spiral flow channel 132 means that the flow channel position is correspondingly arranged and the number of flow channels is correspondingly arranged. The flow channel direction of the auxiliary flow channel is not limited in the embodiment of the application.
[0065] It should be noted that the number of liquid inlets 123 can be set according to actual needs to increase the ability of uniform temperature.
[0066] It should be noted that, as shown in Figure 1 , Figure 2 and Figure 7 , the auxiliary flow channel is formed by dividing the space enclosed by the two end first flanges 154 of the water feeding roller 150 and the inner side wall of the inner roller 120 through the auxiliary guide plate 151. The first flange 154 of one end of the water feeding roller 150 and the second flange 126 of the same end of the inner roller 120 form a water outlet cavity 125 therebetween, and the water outlet cavity 125 is arranged close to the first liquid inlet 1311 of the first spiral flow channel. The water outlet cavity 125 is in communication with the second liquid outlet 1322 of the second spiral flow channel 132; a water separation plate is further arranged between the two first flanges 154 of the water feeding roller 150, and the water separation plate and the inner side wall of the water feeding roller 150 enclose to form a sandwich layer 152, and the water separation plate and the outer side wall of the central water conveying pipe 140 form a water outlet flow channel 122, the inlet end of the water outlet flow channel 122 is in communication with the water outlet cavity 125, and the water outlet flow channel 122 is connected with a water conveying pipe 160, one end of the water conveying pipe 160 away from the water outlet flow channel 122 is in communication with the flow channel outlet 127, so as to convey the water in the water outlet cavity 125 along the water outlet flow channel 122 to the flow channel outlet 127, and the flow channel outlet 127 is arranged on the first flange 154 of the inner roller 120 close to the first liquid outlet 1312. In some embodiments, a heat insulation plate 153 is further arranged between the flanges of the two ends of the water feeding roller 150, the heat insulation plate 153 is arranged close to the central water conveying pipe 140, and the heat insulation plate 153 and the water separation plate form the water outlet flow channel 122.
[0067] It should be noted that the preset ratio can be set according to needs, for example, set to three quarters, then one fourth of the water is left in the spiral flow channel, and three fourths of the water flows to the auxiliary flow channel.
[0068] It can be understood that, as shown in Figure 6As shown, the detection assembly is provided with at least three groups, three detection members 210 on the first spiral flow channel 131 are sequentially arranged between the first liquid inlet 1311 and the corresponding water distribution plate 124, between the corresponding water distribution plate 124 and the liquid inlet 123, and between the first liquid outlet 1312 of the first spiral flow channel 131 and the corresponding liquid inlet 123.

The second flange 126 close to the inlet end of the central water delivery pipe 140 and the first flange 154 of the water delivery roller 150 constitute a water outlet chamber 125, which is in communication with the second liquid outlet 1322 of the second spiral flow channel 132 and the inlet end of the water outlet flow channel 122. The water delivery pipe 160 is provided with a plurality of water delivery pipes 160, one end of each of the plurality of water delivery pipes 160 is in communication with the outlet end of the water outlet flow channel 122, and the other end of each of the water delivery pipes 160 is in one-to-one correspondence with the flow channel outlet 127 to guide the water flow in the water outlet flow channel 122 to the outside. The first liquid inlet 1311 close to the first spiral flow channel 131 and the second liquid inlet 1321 close to the second spiral flow channel 132 are each provided with a water distribution plate 124, which guides 3 / 4 of the water in the corresponding flow channel into the auxiliary flow channel of the water delivery roller 150, and the water transported by the auxiliary flow channel is combined with the water in the countercurrent spiral flow channel on the corresponding inner roller 120 through the liquid inlet 123 arranged on the inner roller 120, thereby reducing the water temperature in the spiral flow channel. The inner side wall of the outer roller 110 has a spiral copper sheet, which utilizes the superior heat conductivity of copper to transfer heat from a high-temperature place to a low-temperature place. At this time, the flow channel data of the two flow channels is obtained according to the temperature detected by the temperature sensor, and the pressure adjustment data is obtained by processing the flow channel data through an automatic adjustment model and adjusting the liquid inlet pressure according to the pressure adjustment data. At this time, the water of the first flow direction passes through the following paths in sequence: the water inlet chamber formed by the third flange 112 and the second flange 126 -> the first liquid inlet 1311 -> the water distribution plate 124 (the upper part of the water distribution plate enters the first spiral flow channel 131, and the lower part of the water distribution plate enters the corresponding auxiliary flow channel) -> the water in the auxiliary flow channel and the water in the first spiral flow channel 131 are combined through the liquid inlet -> the second liquid outlet 1322 flows out; the water of the second flow direction passes through the following paths in sequence: the inlet end of the central water delivery pipe 140 -> the second liquid inlet 1321 -> the water distribution plate 124 (the upper part of the water distribution plate enters the second spiral flow channel 132, and the lower half of the water distribution plate enters the corresponding auxiliary flow channel) -> the water in the auxiliary flow channel and the water in the second spiral flow channel 132 are combined through the liquid inlet -> the second liquid outlet 1322 -> the water outlet chamber 125 -> the water outlet flow channel 122 -> the water delivery pipe 160 -> the flow channel outlet 127. At this time, the cooling roller is single-sidedly fed with water and single-sidedly discharged with water, thereby reducing the use of auxiliary facilities.
[0071] Referring to Figures 1 to 8 As shown, the outer roller 110, the inner roller 120, and the water delivery roller 150 are annular hollow cylindrical structures.
[0072] The flow channels on the inner roller 120 are all sealed by the outer roller 110 and the inner surface of the inner roller 120. Among them, the first spiral flow channel 131 and the second spiral flow channel 132 are both closed by the outer roller 110, the inner roller 120 and the main guide plate 121, and the auxiliary flow channel is closed by the inner roller 120, the water feeding roller 150 and the auxiliary guide plate 151. The first spiral flow channel 131 and the second spiral flow channel 132 both have three detection points of temperature sensors, and the automatic adjustment system automatically adjusts the liquid inlet pressure through the automatic adjustment model according to the temperature detected by the temperature sensor.
[0073] Therefore, the present application provides a double-layer spiral flow channel mirror cooling roller based on intelligent adjustment, which achieves uniform distribution of the roller surface temperature through the cross convection of cooling water and the intelligent control of water pressure, so that the cooling of the cast film is more uniform, the water is fed from one side and discharged from the other side, and the sealing and heat insulation requirements are reduced.
[0074] The auxiliary flow channel on the water feeding roller 150 is also provided with a water baffle 170 to force the cooling medium in the auxiliary flow channel to enter the spiral flow channel of the inner roller 120 through the liquid inlet 123 of the inner roller 120. Among them, the spiral copper sheet conducts heat from high places to low places as much as possible. Further, the forward and reverse spiral flow channels all have three detection points of temperature sensors, and the temperature sensors of the forward and reverse spiral flow channels are arranged in pairs, the detection points detect the corresponding temperature, and it is judged whether the temperature difference of each pair of left and right flow channels is within the allowable range, if the difference is too large, the water pressure of the flow channel is increased or decreased, so as to reduce the temperature difference, and according to the temperature values of the three temperature sensors of the forward spiral flow channel (reverse spiral flow channel), it is judged whether the difference between the three temperature sensors is too large and whether it is within the specified temperature range, if the difference is too large or the temperature is not within the allowable range, the water pressure of the forward spiral flow channel (reverse spiral flow channel) is changed, and then the water pressure of the spiral flow channel in the other direction is adjusted according to the difference between the two spiral flow channels, forming a dynamic circulation control of the water pressure.
