Description

Technical Field

[0001] This utility model relates to the field of evaporation coating equipment technology, and more specifically, to a cooling roller mechanism and evaporation coating equipment. Background Technology

[0002] In related technologies, during evaporation coating, the saturated vapor temperature of aluminum is very high, resulting in a significant amount of heat being absorbed by the base film. However, polymer materials such as PET (Polyethylene Terephthalate, commonly known as polyester resin) generally have low soft glass state temperatures and poor high-temperature resistance. When the temperature of the base film exceeds its soft glass state temperature, problems such as tension lines, edge curling, and even melting may occur. Therefore, the base film is typically wound around a cooling roller to cool it down. However, current cooling rollers exhibit significant surface temperature differences, resulting in poor cooling effectiveness and severely impacting product quality.

[0003] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Utility Model Content

[0031] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0033] According to one embodiment of this application, a cooling roller mechanism is provided. Figures 1 to 6 As shown, the cooling roller mechanism includes a roller body 1, which has a first end 11 and a second end 12 disposed opposite to each other. The roller body 1 is provided with a cooling channel 13, which includes a first channel 131 and a second channel 132. The liquid inlet of the first channel 131 is located at the first end 11, the liquid outlet of the first channel 131 is located at the second end 12, the liquid inlet of the second channel 132 is located at the second end 12, and the liquid outlet of the second channel 132 is located at the first end 11.

[0034] In this example, the roller body 1 is provided with a cooling channel 13 extending from a first end 11 to a second end 12. The cooling channel 13 includes a first channel 131 and a second channel 132. The inlet of the first channel 131 is located at the first end 11, and the outlet of the first channel 131 is located at the second end 12. Coolant enters the first channel 131 from the inlet at the first end 11, flows along the first channel 131, and then flows out from the outlet at the second end 12. The inlet of the second channel 132 is located at the second end 12, and the outlet of the second channel 132 is located at the first end 11. Coolant enters the second channel 132 from the inlet at the second end 12, flows along the second channel 132, and then flows out from the outlet at the first end 11. The roller body 1 of this application has a uniform surface temperature, which is beneficial for improving the cooling effect.

[0035] like Figure 1 As shown, in this example, the first end 11 of the roller body 1 is provided with a first liquid inlet 14A of the first channel 131, and the second end 12 of the roller body 1 is provided with a first liquid outlet 15A of the first channel 131. The second end 12 of the roller body 1 is provided with a second liquid inlet 14B of the second channel 132, and the first end 11 of the roller body 1 is provided with a second liquid outlet 15B of the second channel 132.

[0036] The cooling roller mechanism can be used in evaporation coating equipment. The surface of the roller body 1 can be used to wrap the base film. The roller body 1 can uniformly cool the base film, which is beneficial to improving the quality of the product.

[0037] In this example, the roller body 1 can be cylindrical, with the first end 11 and the second end 12 located at opposite ends of the roller body 1 along its axial direction. Cooling channels 13 are arranged along the roller body 1. The sidewalls of the roller body 1 can be used to wind the base film. Specifically, the inlet of the first channel 131 is located at the first end 11 along the axial direction of the roller body 1, and the first channel 131 extends axially to the second end 12. The inlet of the second channel 132 is located at the second end 12 along the axial direction of the roller body 1, and the second channel 132 extends axially to the first end 11. Alternatively, the roller body 1 can have other shapes, which can be determined by those skilled in the art according to the actual situation, and are not specifically limited here.

[0038] In this example, the roller 1 can be made of materials such as aluminum alloy, stainless steel, carbon structural steel, or alloy steel, which have good thermal conductivity and can quickly dissipate heat. Furthermore, these materials can withstand high pressure and temperature to adapt to different environments. Of course, the specific material of the roller 1 can be determined by those skilled in the art based on actual conditions, and no specific limitations are made here.

[0039] In one example, such as Figure 1 and Figure 2 As shown, the cooling channel 13 has a spiral structure coiled around the roller body 1.

[0040] In this example, the first channel 131 has a spiral structure and is coiled around the surface of the roller body 1. The second channel 132 also has a spiral structure and is coiled around the surface of the roller body 1. Coolant can flow within the first channel 131 and the second channel 132. By setting the cooling channel 13 into a spiral structure, the area of ​​the cooling channel 13 can be increased, thereby improving the cooling effect.

[0041] In this example, both the first channel 131 and the second channel 132 are spiral structures, and the first channel 131 and the second channel 132 can be set alternately.

[0042] In one example, multiple first channels 131 and / or second channels 132 are provided. By providing multiple first channels 131 and second channels 132, it is beneficial to further improve the uniformity of the surface temperature of the roller body 1, thereby improving the cooling effect.

[0043] For example, in this example, both the first channel 131 and the second channel 132 are spiral structures. There are two of each of the first channel 131 and the second channel 132, or four or eight of each of the first channel 131 and the second channel 132, etc. Those skilled in the art can decide according to the actual situation, and no specific limitation is made here.

[0044] Alternatively, in this example, one first channel 131 can be configured, and multiple second channels 132 can be configured. Or, one second channel 132 can be configured, and multiple first channels 131 can be configured. Of course, the specific number of first channels 131 and second channels 132 can be determined by those skilled in the art based on actual circumstances, and no specific limitation is made here.

[0045] In this example, the first channel 131 and the second channel 132 are alternately arranged, which helps to further improve the uniformity of the surface temperature of the roller 1, thereby improving the cooling effect. For example, both the first channel 131 and the second channel 132 are spiral structures. At the position between the two ends of the roller 1, the two sides adjacent to the first channel 131 are the second channel 132, and the two sides adjacent to the second channel 132 are the first channel 131.

[0046] In this example, the first channel 131 and the second channel 132 can also have other structures. For example, the first channel 131 and the second channel 132 can be straight channels or curved channels arranged along the axial direction of the roller body 1, and the first channel 131 and the second channel 132 can be alternately arranged at intervals along the circumference of the roller body 1. Of course, the specific structure and arrangement of the first channel 131 and the second channel 132 can be determined by those skilled in the art according to the actual situation, and no specific limitation is made here.

[0047] In one example, such as Figure 1 As shown, the first channel 131 and the second channel 132 are provided with a diverter plate 16.

[0048] like Figure 1 As shown, in this example, a flow divider 16 is provided in the first channel 131 and the second channel 132, which can play a flow dividing role, thereby making the coolant flow more evenly in the first channel 131 and the second channel 132.

[0049] In this example, a diverter 16 can be provided at a wider position within the first channel 131 and the second channel 132. For example, as Figure 1 As shown, both the first channel 131 and the second channel 132 are spiral structures with a larger width at the inlet and outlet positions, and a flow divider 16 is provided near the inlet and outlet positions respectively.

[0050] In one example, such as Figure 2 and Figure 3 As shown, the cooling roller mechanism also includes a sealing element 17. The surface of the roller body 1 is provided with a groove 18. The sealing element 17 is sleeved on the outer periphery of the roller body 1 to form the cooling channel 13 with the groove 18.

[0051] like Figure 2 and Figure 3 As shown, the surface of the roller body 1 is provided with a groove 18, and the sealing member 17 can be a sealing sleeve. The sealing member 17 is sleeved on the outer periphery of the roller body 1, thereby sealing the opening of the groove 18. The sealing member 17 forms a first channel 131 and a second channel 132 with the groove 18. The base film can be wound around the outer surface of the sealing member 17. The sealing member 17 can play a heat conduction role, and the base film can be cooled through the sealing member 17.

[0052] In this example, the depth and width of the groove 18 can be set according to the flow rate and pressure, with the overall design aiming to prevent laminar flow within the cooling channel 13. Those skilled in the art can determine this based on actual circumstances; no specific limitations are made here.

[0053] In this example, the seal 17 can be made of materials such as aluminum alloy, stainless steel, carbon structural steel, or alloy steel, which have good thermal conductivity and can quickly dissipate heat. Furthermore, these materials can withstand high pressure and temperature to adapt to different environments. Of course, the specific material of the seal 17 can be determined by those skilled in the art based on actual circumstances, and no specific limitations are made here.

[0054] like Figures 1 to 3As shown, in this example, a partition 19 is provided on the surface of the roller body 1. One end of the partition 19 is connected to the roller body 1, and the other end extends outward along the radial direction of the solid. The partition 19 can be a spiral structure, forming a groove 18. A sealing member 17 is sleeved on the partition 19 and abuts against the top end of the partition 19, thereby sealing the groove 18 to form a cooling channel 13. Multiple sets of partitions 19 can be provided to form a first channel 131 and a second channel 132.

[0055] It should be noted that the partition 19 can be welded or bonded to the roller body 1, which is a simple and easy-to-operate connection method. Alternatively, the partition 19 can also be integrally formed with the roller body 1, which can simplify the overall assembly process of the cooling roller. Of course, the specific configuration of the partition 19 can be determined by those skilled in the art according to the actual situation, and no specific limitation is made here.

[0056] In this example, the groove 18 can also be formed by an inward recess on the surface of the roller 1. Of course, those skilled in the art can determine the specific structure of the groove 18 according to the actual situation, and no specific limitation is made here.

[0057] In one example, such as Figures 3 to 6 As shown, the cooling roller mechanism also includes a first tube 2 and a second tube 3. The liquid inlet is connected to the refrigerator 4 through the first tube 2, and the liquid outlet is connected to the refrigerator 4 through the second tube 3.

[0058] like Figures 3 to 6 As shown, in this example, one end of the first pipe 2 is connected to the liquid inlet, and the other end is connected to the liquid outlet of the refrigerator 4. One end of the second pipe 3 is connected to the liquid outlet, and the other end is connected to the liquid inlet of the refrigerator 4. The coolant in the refrigerator 4 flows into the cooling channel 13 through the first pipe 2, and then flows back to the refrigerator 4 through the second pipe 3 to complete the coolant circulation.

[0059] In this example, the refrigerator 4 is provided with a liquid storage chamber, and the first pipe 2 is connected to the liquid outlet of the liquid storage chamber. The refrigerator 4 also includes a refrigeration mechanism, so that the coolant flowing out from the second pipe 3 can be cooled by the refrigeration mechanism before flowing back to the liquid inlet of the liquid storage chamber, so as to ensure the temperature of the coolant flowing from the first pipe 2 to the cooling channel 13, thereby ensuring the cooling effect.

[0060] like Figure 2 and Figure 3 As shown, in this example, the cooling roller mechanism also includes a rotating shaft 7, which is connected to the roller body 1. The base film is wound around the roller body 1, and can drive the roller body 1 to rotate during winding or unwinding, thereby improving the smoothness of winding or unwinding and preventing the base film from being damaged by excessive friction. The rotating shaft 7 passes through the roller body 1, and the first tube 2 and the second tube 3 can be embedded in the rotating shaft 7.

[0061] In one example, such as Figure 3 As shown, the first tube 2 is sleeved on the second tube 3.

[0062] In this example, the outer diameter of the second tube 3 is smaller than the inner diameter of the first tube 2. The second tube 3 is disposed inside the first tube 2 and can pass through the end of the first tube 2, with the end of the first tube 2 sealed. A gap exists between the first tube 2 and the second tube 3 for the flow of coolant, and this gap can communicate with the inlet. Coolant flows through the interior of the second tube 3, and the second tube 3 can communicate with the outlet.

[0063] Alternatively, the first tube 2 and the second tube 3 can be arranged in parallel. Those skilled in the art can decide according to the actual situation, and no specific limitation is made here.

[0064] Alternatively, the first tube 2 can be a trough with the rotating shaft 7 arranged axially, and the second tube 3 can be inserted through the trough. The end of the trough is provided with a sealing structure. There is a gap between the inner wall of the trough and the outer wall of the second tube 3 to form the first tube 2. The side wall of the rotating shaft 7 is provided with a connecting hole, which connects to the trough. The liquid inlet pipe 5 is connected to the connecting hole.

[0065] In one example, such as Figures 2 to 5 As shown, the cooling roller mechanism also includes an inlet pipe 5 and an outlet pipe 6. The first pipe body 2 is connected to the inlet through the inlet pipe 5, and the second pipe body 3 is connected to the outlet through the outlet pipe 6.

[0066] like Figure 2 and Figure 3 As shown, in this example, multiple inlet pipes 5 are provided, and multiple connecting holes are correspondingly provided on the side wall of the first pipe body 2. One end of the inlet pipe 5 is connected to a connecting hole, and the other end is connected to the second inlet port 14B of the second end 12. Figure 4 and Figure 5 As shown, one end of the liquid inlet pipe 5 is connected to the connecting hole, and the other end is connected to the first liquid inlet 14A of the first end 11. Multiple first channels 131 and multiple second channels 132 are provided, and multiple liquid inlet pipes 5 are correspondingly provided.

[0067] like Figure 2 and Figure 3 As shown, in this example, multiple outlet pipes 6 are provided, and multiple connecting holes are correspondingly provided on the side wall of the second pipe body 3. One end of the outlet pipe 6 is connected to a connecting hole, and the other end is connected to the second outlet 15B of the first end 11. Figure 4 and Figure 5As shown, one end of the liquid outlet pipe 6 is connected to the connecting hole, and the other end is connected to the first liquid outlet 15A of the second end 12. Multiple first channels 131 and multiple second channels 132 are provided, and multiple liquid outlet pipes 6 are correspondingly provided.

[0068] In this example, the roller body 1 can be a hollow structure, which can reduce the weight of the roller body 1 and also facilitate the placement of the inlet pipe 5 and outlet pipe 6 inside the roller body 1, thereby benefiting the structural arrangement of the cooling roller mechanism.

[0069] According to a second aspect of the present invention, an evaporation coating apparatus is provided. This evaporation coating apparatus includes the cooling roller mechanism described in the above embodiments. Figures 1 to 6 As shown, the cooling roller mechanism includes a roller body 1, which has a first end 11 and a second end 12 disposed opposite to each other. The roller body 1 is provided with a cooling channel 13, which includes a first channel 131 and a second channel 132. The inlet of the first channel 131 is located at the first end 11, and the outlet of the first channel 131 is located at the second end 12. The inlet of the second channel 132 is located at the second end 12, and the outlet of the second channel 132 is located at the first end 11. The cooling channel 13 extends from the first end 11 to the second end 12. Coolant enters the first channel 131 from the inlet at the first end 11, flows along the first channel 131, and then flows out from the outlet at the second end 12. The inlet of the second channel 132 is located at the second end 12, and the outlet of the second channel 132 is located at the first end 11. The coolant enters the second channel 132 from the inlet at the second end 12, flows along the second channel 132, and then flows out from the outlet at the first end 11. The surface temperature of the roller body 1 in this application is uniform, which is beneficial to improving the cooling effect.

[0070] In this example, the evaporation coating equipment also includes a cavity and a cover plate. An evaporation boat is housed within the cavity, and a roller 1 is mounted on the cover plate. A take-up roller and an unwind roller are also mounted on the cover plate. The base film is wound around the roller 1, the take-up roller, and the unwind roller. The cover plate can drive the roller 1, the take-up roller, and the unwind roller into the cavity, and the cover plate can seal the opening of the cavity. The roller 1 is located above the evaporation boat, thus enabling evaporation coating of the base film surface. During evaporation coating, the roller 1 can cool the base film.

[0071] Of course, the cooling roller mechanism can also be used in other equipment, as can be determined by those skilled in the art based on the actual situation, and no specific limitation is made here.

[0072] The above embodiments mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be elaborated here.

[0073] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
