Description

Technical Field

[0001] This utility model belongs to the field of surface treatment technology, specifically an aluminum coil coating cooling device. Background Technology

[0002] Aluminum is susceptible to oxidation under certain environmental conditions, especially when exposed to highly corrosive environments such as humidity and salt spray. Coating can form a protective film on the surface of aluminum coils, effectively preventing oxidation and corrosion, thereby extending the service life of the aluminum. During the coating process, if the temperature of the aluminum coil is too high, it may deform or warp, affecting product quality and subsequent processing. By using a cooling device, deformation of the aluminum coil due to high temperature during the coating process can be effectively avoided, ensuring that the aluminum coil remains flat.

[0003] The principle of aluminum coil coating cooling equipment mainly involves two aspects: heat conduction and liquid cooling. By applying precise heat conduction and liquid cooling principles, the aluminum coil coating cooling equipment can efficiently cool the coated aluminum coil, providing strong support for subsequent processing.

[0004] Existing cooling devices mostly use spray cooling water to cool aluminum coils after coating. Since the cooling water cannot be effectively recycled during use, a large amount of water resources are wasted on large production lines. Therefore, an aluminum coil coating cooling device is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, most existing cooling devices use spray cooling water to cool the aluminum coils after coating. Since the cooling water cannot be effectively recycled during use, it leads to a waste of a lot of water resources on large production lines. This utility model proposes an aluminum coil coating cooling device.

[0006] The technical solution adopted by this utility model to solve its technical problem is an aluminum coil coating cooling device, including a workbench. A spraying equipment body is fixedly installed at one end of the top of the workbench, and a cooling roller is provided at the other end of the top of the workbench. Rotating shafts are fixedly installed on both sides of the cooling roller. A first drive motor is provided on one side of the cooling roller, and the output end of the first drive motor is installed inside one of the rotating shafts. A fixed pipe is provided on the other side of the cooling roller, and one end of the fixed pipe is rotatably installed on the side of the other rotating shaft. A first infusion pipe is fixedly installed inside the fixed pipe. One end of the first infusion pipe passes through the inside of the rotating shaft and is rotatably installed on one side of the inner wall of the cooling roller. A drain port is provided on the outside of one end of the first infusion pipe. The other end of the first infusion pipe is fixed... An electric valve is installed, with a liquid storage tank external to the input end of the electric valve. A feed port is opened on one side of the liquid storage tank. A semiconductor cooler is installed on the top of the liquid storage tank, and a water pump is installed at one end of the bottom of the liquid storage tank. The output end of the water pump is installed inside the liquid storage tank, and a second liquid delivery pipe is installed at the input end of the water pump. The end of the second liquid delivery pipe away from the water pump is installed inside the fixed pipeline. The aluminum coil after spraying is cooled by a cooling roller. When the temperature of the internal coolant of the cooling roller rises due to long-term use, the electric valve is opened to allow the cooled coolant to flow into the cooling roller to cool down the heated coolant. The overflowing coolant is pumped into the liquid storage tank for cooling, achieving the effect of reusing the coolant and saving resources.

[0007] Preferably, a first support leg is fixedly installed at both ends of one side of the workbench, and a second support leg is fixedly installed at both ends of the other side of the workbench. Feeding rollers and collecting rollers are respectively provided between multiple first and second support legs. A second drive motor is provided on the side of one of the first support legs. A rotating block is installed through the interior of the first support leg at the output end of the second drive motor. The side of the rotating block is connected to one side of the collecting roller. The second drive motor drives the rotating block to rotate, and the rotation of the rotating block drives the collecting roller to rotate. When the collecting roller rotates, it will carry out the aluminum coil outside the feeding roller for collection, so as to achieve the effect of collection directly after coating.

[0008] Preferably, one of the first support legs has a connection port inside, and one end of the feeding roller is located outside the connection port. Multiple second support legs each have an installation groove inside, located both inside and on the side of the second support legs. Each installation groove has a baffle installed inside it. One side of each feeding roller and collecting roller is tightly attached to the outside of the baffle. The baffle limits one end of the collecting roller and feeding roller. When the baffle is removed, it releases the restriction on one end of the collecting roller and feeding roller. Pulling the collecting roller and feeding roller backward when the baffle releases the restriction allows for disassembly of one end of the collecting roller and feeding roller, facilitating the collection of multiple batches of aluminum coils later.

[0009] Preferably, the rotating block has multiple connecting grooves inside, and multiple connecting rods are fixedly installed on one side of the collecting roller. One end of the connecting rod is located outside the connecting groove. The connection between the connecting rod and the connecting groove achieves the effect of driving the collecting roller to rotate while the rotating block rotates.

[0010] Preferably, the first drive motor, the semiconductor cooler, the water pump, the electric valve, and the second drive motor are all electrically connected to an external control center. The control center is used to control the start and stop of the first drive motor, the semiconductor cooler, the water pump, the electric valve, and the second drive motor. Through the connection between the control center and multiple devices, the control of multiple devices can be more conveniently controlled.

[0011] Preferably, multiple fixing plates are fixedly installed at both ends of the top of the workbench, and pressing rollers are rotatably installed between the multiple fixing plates. The pressing rollers press down on the aluminum coils during transportation to prevent them from bulging and affecting the receiving of materials.

[0012] Preferably, fixed brackets are fixedly installed on both sides of the top of the workbench. The fixed brackets are semi-circular arc-shaped, and the inner wall of the fixed brackets is tightly attached to the outside of the rotating shaft. The semi-circular fixed brackets are evenly attached to the rotating shaft to achieve the effect of supporting the rotating shaft.

[0013] The advantages of this utility model are:

[0014] This invention addresses the problem of existing cooling devices that rely on sprayed cooling water to cool the surface of coated aluminum coils during the coating process. The cooling device uses a cooling roller to cool the coated aluminum coil. When the internal coolant temperature of the cooling roller rises due to prolonged use, an electric valve is opened to allow the cooled coolant to flow back into the roller to cool it down. Excess coolant is pumped into a storage tank for further cooling, thus achieving the effect of reusing the coolant. This solves the problem that existing cooling devices often use sprayed cooling water to cool the coated aluminum coil, resulting in significant water waste on large production lines due to the inability to effectively recycle the cooling water. By reusing the coolant, the invention achieves resource conservation. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-5 As shown, an aluminum coil coating cooling device includes a workbench 1. A spraying equipment body 4 is fixedly mounted on one end of the top of the workbench 1. A cooling roller 5 is provided on the other end of the top of the workbench 1. Rotating shafts 6 are fixedly mounted on both sides of the cooling roller 5. A first drive motor 7 is provided on one side of the cooling roller 5, and the output end of the first drive motor 7 is installed inside one of the rotating shafts 6. A fixed pipe 8 is provided on the other side of the cooling roller 5, and one side of the fixed pipe 8 is rotatably mounted on the side of the other rotating shaft 6. The interior of the fixed pipe 8... A first infusion tube 9 is fixedly installed. One end of the first infusion tube 9 passes through the interior of the rotating shaft 6 and is rotatably mounted on one side of the inner wall of the cooling roller 5. A drain port 13 is provided on the outside of one end of the first infusion tube 9. An electric valve 16 is fixedly installed on the other end of the first infusion tube 9. A storage tank 10 is provided on the outside of the input end of the electric valve 16. A feed port 12 is provided on one side of the outside of the storage tank 10. A semiconductor cooler 11 is installed on the top of the storage tank 10. A water pump 15 is provided at one end of the bottom of the storage tank 10. The output end is installed inside the liquid storage tank 10. The input end of the water pump 15 is equipped with a second liquid delivery pipe 14. The end of the second liquid delivery pipe 14 away from the water pump 15 is externally installed inside the fixed pipeline 8. During operation, existing cooling devices waste water resources due to the large amount of water used for spray cooling of the outer surface of the aluminum coil, which cannot be recycled. In order to recycle water resources, this device uses a cooling roller 5 to cool the outer surface of the coated aluminum coil. When the internal coolant temperature of the cooling roller 5 rises after long-term use, it is cooled by semiconductor refrigeration. The device 11 cools the coolant inside the storage tank 10. After cooling is complete, the electric valve 16 is opened, and the cooled coolant is delivered to the cooling roller 5 through the first delivery pipe 9 to cool down the heated coolant. When the coolant inside the cooling roller 5 is cooling down, the overflowing coolant will flow into the second delivery pipe 14 through the holes opened inside the cooling roller 5 and the rotating shaft 6. At this time, the water pump 15 is started to draw the overflowing coolant into the storage tank 10 and continue to be cooled by the semiconductor cooler 11, so as to achieve the effect of recycling the coolant.

[0024] The workbench 1 has first support legs 21 fixedly installed at both ends on one side, and second support legs 22 fixedly installed at both ends on the other side. Feeding rollers 2 and collecting rollers 3 are respectively provided between multiple first support legs 21 and second support legs 22. A second drive motor 23 is provided on the side of one of the first support legs 21. The output end of the second drive motor 23 passes through the interior of the first support leg 21 and is equipped with a rotating block 24. The side of the rotating block 24 is connected to one end of the collecting roller 3. During operation, existing cooling devices waste a lot of water resources when cooling the aluminum coil by spraying the outer surface of the aluminum coil, which cannot be recycled. In order to recycle water resources, this device drives the collecting roller 3 to rotate through the second drive motor 23. When the collecting roller 3 rotates, it will carry the aluminum coil outside the feeding roller 2 out, realizing the effect of collecting material during the aluminum coil spraying process.

[0025] One of the first support legs 21 has a connection port 29 inside. One end of the feeding roller 2 is located outside the connection port 29. Multiple second support legs 22 each have an installation groove 27 inside. The installation groove 27 is located inside and on the side of the multiple second support legs 22. Each of the multiple installation grooves 27 has a baffle 28 installed inside. One side of each feeding roller 2 and collecting roller 3 is tightly attached to the outside of the baffle 28. During operation, existing cooling devices waste water resources due to the large amount of water used for spray cooling of the aluminum coil's outer surface, which cannot be recycled. This device, to achieve water recycling, places one end of the feeding roller 2 and collecting roller 3 in the installation groove 27 and limits their movement using the baffle 28. When the baffle 28 is removed, one end of the feeding roller 2 and collecting roller 3 is no longer limited. At this point, the feeding roller 2 and collecting roller 3 can be pushed further into the installation groove 27, achieving the effect of detachable feeding roller 2 and collecting roller 3.

[0026] The rotating block 24 has multiple connecting grooves 25 inside, and multiple connecting rods 26 are fixedly installed on one side of the collecting roller 3. One end of the connecting rod 26 is located outside the connecting groove 25. During operation, existing cooling devices waste water resources by spraying the outer surface of the aluminum coil, which cannot be recycled. In order to recycle water resources, this device connects one end of the collecting roller 3 to the rotating block 24 by connecting the connecting rod 26 to the connecting groove 25. Furthermore, the collecting roller 3 can be disassembled by pulling it out backward during the connection process.

[0027] The first drive motor 7, the semiconductor cooler 11, the water pump 15, the electric valve 16, and the second drive motor 23 are all electrically connected to an external control center. The control center is used to start and stop the first drive motor 7, the semiconductor cooler 11, the water pump 15, the electric valve 16, and the second drive motor 23. During operation, existing cooling devices waste a large amount of water resources when cooling aluminum coils by spraying the outer surface of the aluminum coils, which cannot be recycled. In order to recycle water resources, this device uses the control center to control multiple devices to achieve a more convenient start and stop operation.

[0028] Multiple fixing plates 17 are fixedly installed at both ends of the top of the workbench 1, and pressing rollers 18 are rotatably installed between the multiple fixing plates 17. During operation, the existing cooling device uses a large amount of water resources that cannot be recycled when cooling the outer surface of the aluminum coil, which leads to water waste. In order to recycle water resources, this device presses the aluminum coil with pressing rollers 18 to prevent it from bulging during its movement.

[0029] Fixed brackets 19 are fixedly installed on both sides of the top of the workbench 1. The fixed brackets 19 are semi-circular arc-shaped, and the inner wall of the fixed brackets 19 is tightly attached to the outside of the rotating shaft 6. During operation, the existing cooling device uses a large amount of water resources that cannot be recycled when cooling the outer surface of the aluminum coil. In order to recycle water resources, this device fixes the rotating shaft 6 with fixed brackets 19, so that there is a certain gap between the cooling roller 5 and the workbench 1 for contact cooling.

[0030] Working principle: During the aluminum coil spraying process, a cooling device is used to cool the outer surface of the sprayed aluminum coil. The second drive motor 23 is activated to rotate the rotating block 24. When the rotating block 24 rotates, it drives the connected collecting roller 3 to rotate. At this time, the aluminum coil outside the feeding roller 2 is wound around the collecting roller 3. The rotation of the collecting roller 3 carries the aluminum coil out of the feeding roller 2. As the aluminum coil is carried out, it is sprayed through the spraying equipment body 4 located on the top of the workbench 1. After spraying is completed, the first drive motor 7 drives the cooling roller 5 to rotate, achieving the effect of cooling the outer surface of the sprayed aluminum coil. After cooling is complete, the collected aluminum coil is collected by the collecting roller 3. When the internal coolant temperature of the cooling roller 5 rises due to prolonged use, the semiconductor cooler 11 cools the coolant inside the storage tank 10. After cooling is complete, the electric valve 16 is opened, and the cooled coolant is delivered to the cooling roller 5 through the first liquid delivery pipe 9. The internal cooling system cools the heated coolant. When the coolant inside the cooling roller 5 is cooling down, the overflowing coolant flows through the openings inside the cooling roller 5 and the rotating shaft 6 into the second liquid delivery pipe 14. At this time, the water pump 15 is activated to draw the overflowing coolant into the storage tank 10 for further cooling by the semiconductor cooler 11, achieving a circulating coolant effect. After all the aluminum coils outside the feeding roller 2 have been collected by the collecting roller 3, the contents of the multiple second support legs 22 are removed. The baffle 28 of the part realizes the effect of releasing the restriction on one end of the feeding roller 2 and the collecting roller 3. When one end of the feeding roller 2 and the collecting roller 3 is released from the restriction, they can continue to move into the mounting groove 27. When the feeding roller 2 and the collecting roller 3 continue to move into the mounting groove 27, one end of the feeding roller 2 will be disconnected from the connection inside the first support leg 21, and one end of the collecting roller 3 will be disconnected from the connection between the rotating block 24. Finally, the feeding roller 2 and the collecting roller 3 are detachable, which facilitates the cooling of the next aluminum coil.
