Description

Technical Field

[0001] This application relates to the field of coating technology, and more specifically to a coating system. Background Technology

[0002] As the width of the die head in the coating system gradually increases, the requirements for the consistency of the slurry temperature during coating also gradually increase in order to ensure the surface density and dimensional consistency of the coating. How to control the slurry temperature more precisely has become a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0003] The purpose of this application is to provide a coating system that allows for more precise control of the slurry temperature, resulting in better areal density and dimensional consistency of the coating.

[0004] To solve the above-mentioned technical problems, this application provides a coating system, comprising:

[0005] The coating buffer tank includes a transfer tank, a coating buffer tank, a die head, a first pipeline, and a second pipeline. The coating buffer tank has a first storage cavity for storing slurry and a first temperature-regulating cavity located on the outer periphery of the storage cavity. The first pipeline connects the outlet of the transfer tank and the inlet of the first storage cavity, and the second pipeline connects the outlet of the first storage cavity and the inlet of the die head.

[0006] A first temperature regulating tube and a second temperature regulating tube, the first temperature regulating tube being fitted into the first pipeline, a second temperature regulating cavity being formed between the first temperature regulating tube and the first pipeline, the second temperature regulating tube being fitted into the second pipeline, a third temperature regulating cavity being formed between the second temperature regulating tube and the second pipeline, the third temperature regulating cavity, the first temperature regulating cavity and the second temperature regulating cavity being sequentially connected;

[0007] A temperature regulating mechanism, wherein the outlet of the temperature regulating mechanism is connected to the inlet of the third temperature regulating cavity, and the inlet of the temperature regulating mechanism is connected to the outlet of the second temperature regulating cavity.

[0008] In the coating system of this application, the third temperature regulating cavity, the first temperature regulating cavity, and the second temperature regulating cavity are connected sequentially. The third temperature regulating cavity is closest to the die head. The outlet of the temperature regulating mechanism is connected to the inlet of the third temperature regulating cavity, and the inlet of the temperature regulating mechanism is connected to the outlet of the second temperature regulating cavity. During operation, the heat transfer medium in the temperature regulating mechanism first enters the third temperature regulating cavity, then flows sequentially through the first and second temperature regulating cavities, and then returns to the temperature regulating mechanism. Thus, the heat transfer medium in the temperature regulating mechanism first exchanges heat with the slurry flowing to the second pipeline. Since the second pipeline is directly connected to the die head, the slurry inside the second pipeline will flow directly to the die head after heat exchange. Therefore, by precisely controlling the outlet temperature of the temperature regulating mechanism, the temperature of the slurry inside the second pipeline after heat exchange can be precisely controlled, thereby ensuring that the temperature of the slurry entering the die head is within the required temperature range.

[0009] Meanwhile, after the heat transfer medium in the temperature regulation mechanism flows through the third temperature regulation chamber, it will also flow through the first and second temperature regulation chambers in the opposite direction to the flow direction of the slurry, and exchange heat with the slurry flowing through the coating buffer tank and the first pipeline, which plays a preliminary role in cooling the slurry. As the slurry gradually approaches the die head, its temperature gradually approaches the required temperature range, thereby ensuring that the temperature of the slurry inside the second pipeline is within the required temperature range after exchanging heat with the heat transfer medium in the temperature regulation mechanism, so as to achieve precise control of the slurry temperature as much as possible.

[0010] In summary, the coating system of this application can achieve precise control of the slurry temperature as much as possible, resulting in better areal density and dimensional consistency of the coating.

[0011] Optionally, the inlet of the third temperature-regulating cavity is located at one end near the mold head, and the outlet of the third temperature-regulating cavity is located at one end near the coating buffer tank.

[0012] Optionally, the inlet of the second temperature-controlled chamber is located near the end of the coating buffer tank, and the outlet of the second temperature-controlled chamber is located near the end away from the transfer tank.

[0013] Optionally, it also includes a temperature sensor for detecting the temperature of the slurry, the temperature sensor being disposed at the inlet of the die head.

[0014] Optionally, the second temperature control tube is fitted into the axial portion of the second pipeline, and the second temperature control tube is farther away from the mold head than the temperature sensor.

[0015] Optionally, the system also includes a controller, wherein the temperature regulating mechanism and the temperature sensor are both electrically connected to the controller.

[0016] Optionally, the temperature range of the inlet of the die head is a℃-b℃, the temperature detected by the temperature sensor is c℃, and the outlet temperature of the die temperature controller is (a+bc)℃.

[0017] Optionally, the interior of the coating buffer tank is hollow and forms the storage cavity, and the wall of the coating buffer tank has a sandwich layer, which forms the first temperature regulating cavity.

[0018] Optionally, the transfer tank has a second storage chamber for storing slurry inside, and the transfer tank has a jacket in its wall, the jacket forming a freezing chamber for containing chilled water.

[0019] Optionally, the temperature regulating mechanism is a mold temperature controller. Attached Figure Description

[0023] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a specific embodiment of the coating system provided in this application.

[0025] This application provides a coating system, comprising:

[0026] The container includes a transfer tank 1, a coating buffer tank 2, a die head 3, a first pipeline 4, and a second pipeline 5. The coating buffer tank 2 has a first storage chamber for storing slurry and a first temperature regulating chamber located on the outer periphery of the storage chamber. The first pipeline 4 connects the outlet of the transfer tank 1 and the inlet of the first storage chamber. The second pipeline 5 connects the outlet of the first storage chamber and the inlet of the die head 3.

[0027] The first temperature regulating tube 6 and the second temperature regulating tube 7 are fitted together with the first pipe 4. The first temperature regulating tube 6 and the first pipe 4 form a second temperature regulating cavity. The second temperature regulating tube 7 is fitted together with the second pipe 5. The second temperature regulating tube 7 and the second pipe 5 form a third temperature regulating cavity. The third temperature regulating cavity, the first temperature regulating cavity and the second temperature regulating cavity are connected sequentially.

[0028] Temperature regulating mechanism 8, the outlet of temperature regulating mechanism 8 is connected to the inlet of the third temperature regulating cavity, and the inlet of temperature regulating mechanism 8 is connected to the outlet of the second temperature regulating cavity.

[0029] In the coating system of this application, the third temperature regulating cavity, the first temperature regulating cavity, and the second temperature regulating cavity are connected sequentially. The third temperature regulating cavity is closest to the die head 3. The outlet of the temperature regulating mechanism 8 is connected to the inlet of the third temperature regulating cavity, and the inlet of the temperature regulating mechanism 8 is connected to the outlet of the second temperature regulating cavity. During operation, the heat transfer medium in the temperature regulating mechanism 8 will first enter the third temperature regulating cavity, then flow through the first and second temperature regulating cavities in sequence, and then return to the temperature regulating mechanism 8. Thus, the heat transfer medium in the temperature regulating mechanism 8 will first exchange heat with the slurry flowing to the second pipe 5. Since the second pipe 5 is directly connected to the die head 3, the slurry inside the second pipe 5 will flow directly to the die head 3 after heat exchange. Therefore, by accurately controlling the outlet temperature of the temperature regulating mechanism 8, the temperature of the slurry inside the second pipe 5 after heat exchange can be accurately controlled, thereby ensuring that the temperature of the slurry entering the die head 3 is within the required temperature range as much as possible.

[0030] Meanwhile, after the heat transfer medium in the temperature regulating mechanism 8 flows through the third temperature regulating cavity, it will also flow through the first and second temperature regulating cavities in the opposite direction to the flow direction of the slurry, and exchange heat with the slurry flowing through the coating buffer tank 2 and the first pipeline 4, which plays a preliminary role in cooling the slurry. As the slurry gradually approaches the die head, its temperature gradually approaches the required temperature range, thereby ensuring that the temperature of the slurry inside the second pipeline 5 is within the required temperature range after exchanging heat with the heat transfer medium in the temperature regulating mechanism 8, and achieving precise control of the slurry temperature as much as possible.

[0031] In summary, the coating system of this application adopts a countercurrent design of slurry and heat exchange medium to achieve precise control of slurry temperature as much as possible, resulting in better areal density and dimensional consistency of the coating.

[0032] Please continue to refer to this. Figure 1 In this embodiment, the inlet of the third temperature regulating cavity is located at one end near the mold head 3, and the outlet of the third temperature regulating cavity is located at one end near the coating buffer tank 2.

[0033] As set up above, the flow direction of the heat transfer medium inside the third temperature control chamber is opposite to the flow direction of the slurry inside the second pipe 5. The heat transfer medium first exchanges heat with the slurry located downstream, and then exchanges heat with the slurry located upstream. The slurry inside the second pipe 5 enters the die head 3 after exchanging heat with the latest flowing heat transfer medium. In this way, by controlling the outlet temperature of the temperature regulation mechanism 8, the temperature of the slurry entering the die head 3 can be controlled more precisely.

[0034] Please continue to refer to this. Figure 1In this embodiment, the inlet of the second temperature-regulating chamber is located at one end close to the coating buffer tank 2, and the outlet of the third temperature-regulating chamber is located at one end far from the transfer tank 1.

[0035] As set up above, the flow direction of the heat transfer medium inside the second temperature control cavity is opposite to the flow direction of the slurry inside the first pipeline 4. The heat transfer medium first exchanges heat with the slurry located downstream, and then with the slurry located upstream. This counter-current design creates a temperature difference between the slurry and the heat transfer medium during the flow process, thereby improving the heat exchange efficiency.

[0036] Here, along the flow direction of the slurry, the end closer to the transfer tank 1 is defined as "upstream", and the end closer to the die head 3 is defined as "downstream".

[0037] Please continue to refer to this. Figure 1 The coating system in this embodiment also includes a temperature sensor 9 for detecting the temperature of the slurry, and the temperature sensor 9 is located at the inlet of the die head 3.

[0038] As set up above, the temperature sensor 9 is used to detect the temperature of the slurry at the inlet of the die head 3, so that the temperature of the heat transfer medium flowing out of the outlet of the temperature regulating mechanism 8 can be adjusted in a timely manner according to the detection result of the temperature sensor 9, so as to ensure that the temperature of the slurry entering the die head 3 after heat exchange with the heat exchange medium of the temperature regulating mechanism 8 is within the required temperature range, thereby improving the control accuracy of the coating system in this embodiment.

[0039] In this embodiment, the temperature range of the inlet of the die head 3 is a℃-b℃, the temperature detected by the temperature sensor 9 is c℃, and the outlet temperature of the temperature regulating mechanism 8 is (a+bc)℃.

[0040] Assuming the temperature range of the inlet of the die head 3 is 24℃-25℃, and the temperature detected by the temperature sensor 9 is 24℃, the outlet temperature of the temperature regulating mechanism 8 is adjusted to 25℃. This ensures that after heat exchange between the slurry inside the second pipe 5 and the heat transfer medium in the temperature regulating mechanism 8, its temperature is approximately 24.5℃. In other words, this embodiment consistently adjusts the slurry temperature around the midpoint of the temperature range of the inlet of the die head 3, minimizing the temperature deviation at the inlet of the die head 3 and achieving precise control of the slurry temperature as much as possible.

[0041] Depend on Figure 1 As can be seen, in this embodiment, the second temperature control tube 7 is installed in the axial portion of the second pipeline 5, and the second temperature control tube 7 is farther away from the mold head 3 than the temperature sensor 9.

[0042] Therefore, the placement of the temperature sensor 9 in this embodiment can eliminate the influence of the heat exchange process on the detection results, ensuring that the temperature of the slurry detected by the temperature sensor 9 is the temperature after heat exchange, that is, the final temperature of the slurry entering the die head 3, which facilitates the subsequent control of the outlet temperature of the temperature adjustment mechanism 8 and improves the control accuracy of the coating system in this embodiment.

[0043] Furthermore, in this embodiment, the coating system also includes a controller 10, and the temperature regulating mechanism 8 and the temperature sensor 9 are all electrically connected to the controller 10.

[0044] Thus, the controller 10 can control the outlet temperature of the temperature regulating mechanism 8 in a timely manner according to the detection results of the temperature sensor 9, ensuring that the heat transfer medium flowing out of the temperature regulating mechanism 8 has a preset temperature, thereby improving the control accuracy of the coating system in this embodiment.

[0045] The specific structure and control principle of the controller 10 are existing technologies well known to those skilled in the art, and will not be described in detail here.

[0046] Furthermore, in this embodiment, the interior of the coating buffer tank 2 is hollow and forms a storage cavity, and the wall of the coating buffer tank 2 has a sandwich layer, which forms a first temperature regulating cavity.

[0047] As described above, this embodiment provides an interlayer inside the wall of the coating buffer tank 2 for the heat transfer medium to flow through. This design can increase the contact area between the heat transfer medium and the slurry inside the tank, thereby accelerating heat transfer and improving heat exchange efficiency.

[0048] Furthermore, in this embodiment, the interior of the transfer tank 1 has a second storage cavity for storing slurry, and the wall of the transfer tank 1 has a jacket, which forms a freezing cavity for containing chilled water.

[0049] As described above, this embodiment incorporates a jacket within the wall of the transfer tank 1 for chilled water to flow through. This design increases the contact area between the chilled water and the slurry inside the transfer tank 1, thereby accelerating heat transfer and improving heat exchange efficiency. This ensures that the temperature of the slurry inside the transfer tank 1 remains within the required temperature range. For example, the required temperature range for the slurry entering the die head 3 is 24℃-25℃, and the temperature range for the chilled water is 7℃-14℃. After heat exchange with the chilled water, the temperature of the slurry inside the transfer tank 1 is 26℃-28℃. Thus, after temperature regulation by the coating system of this embodiment, the temperature of the slurry entering the die head 3 can be maintained at 24℃-25℃.

[0050] In addition, in this embodiment, the temperature regulating mechanism 8 is a mold temperature controller.

[0051] Among them, the mold temperature controller is a temperature control device widely used in industrial production. The working principle of the mold temperature controller is to use a circulating heat transfer medium to force the slurry flowing through the coating buffer tank 2, the first pipeline 4 and the second pipeline 5 to achieve and maintain a certain slurry temperature, thereby ensuring the stability and accuracy of the slurry temperature during the coating process.

[0052] Mold temperature controllers can be divided into two main categories according to the different heat transfer media: water-type mold temperature controllers and oil-type mold temperature controllers. Water-type mold temperature controllers use water as the heat transfer circulation medium, while oil-type mold temperature controllers use oil as the heat transfer circulation medium.

[0053] The above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
