Description

Technical Field

[0001] The utility model relates to the technical field of coating plates, in particular to a coating plate with a cooling structure. Background Art

[0002] A coating machine is a device that can further coat or cover the surface of an object or substrate with a certain material, such as liquid, powder, or film. Coating the material on the selected substrate surface can provide the substrate with functions such as protection, decoration, rust prevention, corrosion prevention, or printing. It is widely used in manufacturing, packaging, and energy industries that require functional film coating.

[0003] The coating machine is usually composed of a coating mechanism, a material supply system and a control system. The coating mechanism can evenly coat the material delivered by the material supply system such as a liquid nozzle, a roller, and a conveying platform on the surface of the substrate, while the control system controls the above process to adjust the coating thickness, speed, and other parameters.

[0004] For example, an infrared drying flat plate coating machine is a device that can coat the surface of flat or sheet materials. This coating machine has the function of infrared heating and drying, which can achieve precise synchronous heating, so that the coating is efficiently and evenly heated, which is beneficial to improve the adhesion of the coating and improve the quality of the coating after coating. It is mainly composed of a drying box, an infrared heater, a flat plate transmission system, a control system and a coating system.

[0005] During the operation of the infrared drying flat plate coating machine, the infrared heater generates heat, and the material is sent into the drying box through the flat plate transmission system to achieve rapid drying and coating of the material. However, the existing infrared drying flat plate coating lacks the means of cooling and heat dissipation. During the coating work, it takes an extra long time to cool the coated substrate, resulting in a prolonged development and experimental process and low efficiency. Utility Model Content

[0007] In some preferred embodiments, the coating plate further includes a cooling liquid, which is fluidly disposed in the mesh flow channel and is thermally connected to the mesh flow channel.

[0008] In some preferred embodiments, the shapes of the mesh units include triangles, quadrilaterals, pentagons, hexagons, polygons, or circles.

[0009] In some preferred embodiments, the mesh flow channel is a pipe penetrating inside the substrate, or is formed by the substrate itself.

[0010] In some preferred embodiments, the pipe is made of heat-conducting metal, heat-conducting alloy, or heat-conducting material.

[0011] In some preferred embodiments, the thermally conductive metal includes copper, aluminum, silver, nickel or titanium.

[0012] In some preferred embodiments, the difference between the outer diameter of the pipe and the inner diameter of the pipe is 0.5-1.5 mm.

[0013] In some preferred embodiments, the cooling liquid includes one or more of the following:

[0014] Water, antifreeze, and cold keeping agent.

[0015] In a second aspect, the present invention further provides a coating plate liquid cooling system, which includes the coating plate with the cooling structure.

[0016] In some preferred embodiments, the coated plate liquid cooling system further includes: a coolant tank connected to the coated plate with a cooling structure; and a circulating liquid pump connected to the coated plate with a cooling structure and to the coolant tank.

[0017] The beneficial effects of the utility model are that, in the first aspect, the coating plate with a cooling structure has a working surface, and the working surface is thermally connected to the mesh flow channel, so that the heat received by the working surface is further conducted to the mesh flow channel; then, the cooling liquid is fluidly arranged in the mesh flow channel, and can further receive the heat of the aforementioned mesh flow channel. In the second aspect, it further includes a circulating liquid pump, which can drive the cooling liquid and carry the cooling liquid out of the mesh flow channel and enter the cooling liquid tank, so that the heat carried by the cooling liquid can be eliminated or reset, and the cooling liquid can re-enter the mesh flow channel, and further receive the heat from the working surface and the mesh flow channel thermally connected thereto, and the cycle continues.

[0018] Therefore, the coating plate with cooling structure can be used for cooling and cooling, for example, as part of an infrared drying flat plate coating machine, the user will not have to spend extra time in the general or room temperature heat dissipation steps after drying, but can complete the drying and cooling steps in one step, thereby greatly improving the overall work efficiency and being effective.

[0023] In order to make the above and / or other purposes, effects, and features of the present invention more obvious and understandable, the following is a detailed description of the preferred implementation modes with accompanying drawings:

[0024] Please refer to Figure 1 , Figure 1 Schematic diagram of a coating plate with a cooling structure. In a preferred embodiment, the invention provides a coating plate 10 with a cooling structure, which includes: a substrate 101, having a working surface 1010 and a peripheral surface 1011; a first liquid inlet 1020 and a first liquid outlet 1021, which are respectively arranged on the peripheral surface 1011 and define a first flow direction 10201, formed between the first liquid inlet 1020 and the first liquid outlet 1021; and a mesh flow channel 102, formed in the substrate 101 and thermally connected to the working surface 1010, and communicated with the first liquid inlet 1020 and the first liquid outlet 1021, wherein, again referring to Figure 2 The mesh flow channel 102 further includes along the first flow direction 10201: a first mesh unit group 1022, which is connected to the first liquid inlet 1020 and includes an odd number of mesh units 1024; and a second mesh unit group 1023, which is connected to the first liquid outlet 1021 and includes an even number of mesh units 1024.

[0025] Please refer to Figure 1 Preferably, the working surface 1010 is a plane and can be used for coating, but it is not particularly limited. It is worth mentioning that the mesh flow channel 102 includes Figure 1 , Figure 2 , Figure 3 and Figure 4It is presented in perspective.

[0026] Please refer to Figure 1 In some preferred embodiments, the coated plate further includes a cooling liquid 103, which is fluidly disposed in the mesh flow channel 102 and is thermally connected to the mesh flow channel 102; the cooling liquid 103 flows into the mesh flow channel 102 through the first liquid inlet 1020, and then the cooling liquid 103 flows out of the mesh flow channel 102 through the first liquid outlet 1021; it can be understood that the mesh flow channel 102 may further have a second liquid inlet, or a third liquid inlet, or the mesh flow channel 102 may further have a second liquid outlet, or a third liquid outlet, and so on, without limitation; the mesh flow channel 102 has more liquid inlets or liquid outlets, which is positively correlated with the inlet and outlet of the cooling liquid 103 or the cooling efficiency of the working surface 1010. However, the structure, diameter width, etc. of the mesh flow channel 102 should also be considered as the number of liquid inlets or liquid outlets.

[0027] Please refer to Figure 2 In some preferred embodiments, the mesh unit 1024 has a shape including a triangle, a quadrilateral, a pentagon, a hexagon, a polygon, or a circle, wherein a hexagon is preferred, that is, the mesh flow channel 102 is honeycomb-shaped.

[0028] In some preferred embodiments, the mesh flow channel 102 is disposed through the substrate 101.

[0029] The internal pipe or the substrate 101 is formed by itself, and preferably is a pipe penetrating the inside of the substrate 101. It can be understood here that the purpose of the mesh flow channel 102 is to provide the cooling liquid 103, and it is not limited to the formation method. It can be a pipe penetrating, or a structure formed by the substrate 101 itself; in addition, by using the pipe penetrating method, the composition of the pipe and the substrate 101 can be further separated, that is, the heat conductive metal, heat conductive alloy or heat conductive material used to make the pipe or the substrate 101 can be different. For example, due to the large volume of the substrate 101, the cost of the heat-conducting metal, heat-conducting alloy or heat-conducting material used to make the substrate 101 should be low in order to be cost-effective. However, when the cooling liquid 103 is chemically reactive with the substrate 101 made of the lower-cost component, or the substrate 101 made of the lower-cost component is physically prone to excessive retention of the cooling liquid 103, the mesh flow channel 102 formed by the substrate 101 itself will cause problems in the flow setting of the cooling liquid 103; on the contrary, if the mesh flow channel 102 is arranged in a pipeline, the pipeline can be made of other components, and the amount of heat-conducting metal, heat-conducting alloy or heat-conducting material required for the pipeline may be lower, which will better take into account the flow setting problem of the cooling liquid 103 and cost-effectiveness.

[0030] As mentioned above, the mesh flow channel 102 is thermally connected to the working surface 1010, and the basis of the thermal connection includes: (1) the mesh flow channel 102 or the working surface 1010 is made of thermally conductive material, and (2) the distance between the mesh flow channel 102 and the working surface 1010 is reasonable.

[0031] In some preferred embodiments, the pipe is made of heat-conducting metal, heat-conducting alloy, or heat-conducting material, and the substrate 101 or the working surface 1010 can also be made of heat-conducting metal, heat-conducting alloy, or heat-conducting material. In some preferred embodiments, the heat-conducting metal includes copper, aluminum, silver, nickel or titanium, preferably copper.

[0032] In some preferred embodiments, the difference between the outer diameter of the pipe and the inner diameter of the pipe is 0.5mm-1.5mm, preferably 1mm, wherein the outer diameter of the pipe is 7.25mm-7.75mm, preferably 7.5mm, and the inner diameter of the pipe is 6.25mm-6.75mm, preferably 6.5mm; in some preferred embodiments, the distance between the outer diameter of the pipe and the working surface 1010 is less than 12.75mm, and preferably 6.25mm.

[0033] Please also refer to Figure 1 , Figure 2 and Figure 3In some preferred embodiments, the substrate 101 is a square three-dimensional flat plate, which is defined by a length (L1), a width (L2), and a thickness (L3), and the length (L1), width (L2), and thickness (L3) are preferably 400 mm, 200 mm, and 20 mm, respectively, which is understandable that there is no limitation. When the first liquid inlet 1020 and the first liquid outlet 1021 of the mesh flow channel 102 are respectively arranged on the two surfaces formed by the width (L2) and the thickness (L3), preferably, the first liquid inlet 1020 and the first liquid outlet 1021 are respectively arranged at the center of the two surfaces formed by the width (L2) and the thickness (L3); further, when the mesh unit 1024 is hexagonal in shape, the hexagon is formed on any two surfaces formed by the length (L1) and the width (L2), and the working surface 1010 is also arranged on any surface formed by the length (L1) and the width (L2). In addition, the area enclosed by the shape of the mesh unit 1024 is not strictly limited. In the same sense, the number or density of the mesh unit 1024 formed inside the substrate 101 is also not limited. The actual limitation comes from, for example, when the mesh flow channel 102 is a pipe passing through the inside of the substrate 101, it depends on the diameter of the pipe, relative to the length (L1), width (L2) and thickness (L3) of the substrate 101 itself.

[0034] In some preferred embodiments, the cooling liquid 103 includes one or more of the following: water, antifreeze, and cold keeping agent, without limitation; for example, the antifreeze agent can prevent the formation of ice crystals under low temperature conditions, or the cold keeping agent can increase the amount of heat received; it can be further understood that when the cooling liquid 103 includes multiple different components such as water, antifreeze or cold keeping agent, the ratio between the components is not limited. In addition, the thickness or retention degree of the cooling liquid 103 can be affected by adjusting these components, so that when the cooling liquid 103 is fluidly disposed in the mesh flow channel 102, it can have a better heat receiving effect. In addition, the heat is conducted from the working surface 1010 and the mesh flow channel 102 in sequence on the basis of the thermally conductive connection; further, the cooling liquid 103 can flow alternately, that is, in some preferred embodiments, the cooling liquid 103 can flow into the mesh flow channel 102 from the first liquid inlet 1020 and then flow out from the first liquid outlet 1021; and the frequency of flow alternation, or the length of time from flowing into the mesh flow channel 102 to flowing out of the mesh flow channel 102, can be adjusted so that the heat can be carried out of the mesh flow channel 102 by the cooling liquid 103.

[0035] Please refer to Figure 3 , Figure 3is a schematic diagram of a coating machine 1, which includes the coating plate 10 with a cooling structure, which is arranged on a machine body 11, wherein the substrate 101 is a square three-dimensional flat plate; Figure 3 The coating plate 10 with cooling structure shown is tiltedly arranged on the machine body 11 so that the three-dimensional structure of the coating plate 10 with cooling structure and the mesh flow channel 102 thereof can be more clearly represented, which is an explanatory representation. The arrangement of the coating plate 10 with cooling structure on the machine body 11 is not limited.

[0036] For example Figure 4 As shown, the present invention further provides a coating plate liquid cooling system 2, which includes a coating plate 10 with a cooling structure as described above; in some preferred embodiments, the coating plate liquid cooling system 2 further includes: a coolant tank 20, which is connected to the coating plate 10 with a cooling structure; and a circulating liquid pump 30, which is connected to the coating plate 10 with a cooling structure and is connected to the cooling liquid tank 20; and, the coating plate liquid cooling system 2 further includes a connecting component 40, which is arranged between the coating plate 10 with a cooling structure and the cooling liquid tank 20, between the circulating liquid pump 30 and the cooling liquid tank 20, or between the circulating liquid pump 30 and the coating plate 10 with a cooling structure; wherein, the connecting component 40 includes a silicone hose, a polyethylene hose, or a polyurethane hose, and is not limited, but is preferably a silicone hose.

[0037] In some preferred embodiments, Figure 4 As shown, the coating plate liquid cooling system 2 includes a coating plate 10 with a cooling structure, a coolant tank 20, and a circulating liquid pump 30 forming a closed loop through a connecting component 40, wherein the cooling liquid 103 circulates in the closed loop. Furthermore, the circulating liquid pump 30 can transport the cooling liquid 103 stored in the cooling liquid tank 20 toward the coated plate 10 with a cooling structure, and the cooling liquid 103 can flow into the mesh flow channel 102 through the first liquid inlet 1020; at this time, since the cooling liquid 103 is thermally connected to the mesh flow channel 102, and the mesh flow channel 102 is thermally connected to the working surface 1010, the cooling liquid 103 can receive heat from the working surface 1010, and then flow out of the mesh flow channel 102 through the first liquid outlet 1021; after flowing out of the mesh flow channel 102, the cooling liquid 103 enters the cooling liquid tank 20, and the cooling capacity of the cooling liquid tank 20 returns the cooling liquid 103 to a low temperature state, and then, the circulating liquid pump 30 can transport the cooling liquid 103 stored in the cooling liquid tank 20 toward the coated plate 10 with a cooling structure again, and the cycle is repeated.

[0038] In some preferred embodiments, please refer to Figure 3 or Figure 4 When the coating machine 1 and the coating plate liquid cooling system 2 are used for coating, the working process includes the following steps in sequence: (1) coating step: using the coating machine 1, coating an object on the working surface 1010 of the coating plate 10 with a cooling structure to obtain a coated object; (2) drying and cooling step: drying the coated object, and then using the coating plate liquid cooling system 2, that is, opening the circulating liquid pump 30, so that the cooling liquid 103 that has been pre-cooled in the cooling liquid tank 20 flows into the mesh flow channel 102 through the connecting component 40, thereby quickly cooling the coated object after drying on the working surface 1010.

[0039] The above is only a preferred embodiment of the present invention, but it cannot be used to limit the patent protection scope of the present invention; therefore, any simple equivalent changes and modifications made according to the patent protection scope of the present invention and the contents of the specification still fall within the patent protection scope of the present invention.
