Description

Technical Field

[0001] This invention relates to the field of coating technology, specifically to an organic hydrophilic aluminum foil coating device and its processing technology. Background Technology

[0002] Hydrophilic aluminum foil is made by hydrophilically treating aluminum foil. Through a special process, a hydrophilic layer is coated onto its surface. Condensate quickly disperses on the hydrophilic aluminum foil, preventing condensation and increasing the heat exchange area, thus accelerating cooling and heating. It also effectively avoids noise caused by condensation obstructing airflow. Hydrophilic aluminum foil is a composite material with aluminum foil as the base material. It possesses the good heat dissipation properties of ordinary aluminum foil, while also exhibiting corrosion resistance and hydrophilicity, which ordinary aluminum foil lacks. It is a replacement for ordinary aluminum foil used in air conditioning heat exchangers.

Specifically, the hydrophilic coated aluminum foil comprises a hydrophilic coating applied to an aluminum foil with a thickness of 0.050-0.100 mm. The hydrophilic coating includes a base coating and a top coating. The base coating comprises the following main components: 20-28 wt% epoxy resin containing a curing agent, 9-14 wt% alcohol ether solvent, and the balance water. The top coating comprises the following main components: 8-15 wt% acrylic resin, 2.5-3.5 wt% alcohol ether solvent, and the balance water. This invention's hydrophilic coated aluminum foil, through a more rational coating formula, optimized production process and parameters, and higher processing precision, effectively achieves a higher corrosion resistance level and superior processing performance.

[0019] A processing technology for an organic hydrophilic aluminum foil coating apparatus, comprising the organic hydrophilic aluminum foil coating apparatus as described above, with the following specific processing steps:

[0020] Step 1: Equipment preparation. Insert the rotating roller into the driven pressure block, then rotate the adjusting cylinder to fix the rotating roller in place by the driving pressure block, and then put the feed roller with aluminum foil into the slot.

[0021] Step 2: Material preparation. Prepare the coating material to be coated and place it inside the storage tank. Seal it with a sealing cap. Then pull the aluminum foil around the feed roller, dip roller, support roller and discharge roller, and fix it to the discharge assembly.

[0022] Step 3: Hydrophilic coating. The aluminum foil is cleaned by the cleaning component, then dipped in the coating by the dipping roller, then evenly coated by the uniform coating component, and finally dried through the air outlet before being discharged.

[0023] Compared with the prior art, the technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0024] 1. The groove facilitates the installation of the feeding roller, the limiting groove and sliding groove facilitate the installation of the cleaning component and the uniform coating component, and the discharge component facilitates the installation of the rotating roller. Since the diameter of the driving gear is larger than that of the driven gear, it can drive the fan blades to rotate at high speed. The fan blades allow the outside air to enter through the air inlet, be heated through the heating space, and then sprayed through the air outlet onto the surface of the aluminum foil uniformly coated with hydrophilic material, which can accelerate the drying process and greatly improve the efficiency of the device. Moreover, the transmission setting helps to save power source and save processing steps, greatly improving processing efficiency.

[0025] 2. It can keep the hydrophilic material inside the dipping tank at the bottom of the tank to prevent splashing. Even if the hydrophilic material splashes, it can automatically flow back to the bottom of the dipping tank due to the V-shaped groove structure, preventing resource waste. If there is water dripping from the aluminum foil coating layer, it can flow back into the inside of the dipping tank through the inner groove and through hole, preventing the accumulation of hydrophilic material at the top and affecting the uniformity of coating. The hydrophilic material can flow into the dipping tank through the liquid outlet. When the hydrophilic material inside the dipping tank is above the top of the liquid outlet, the sealed liquid storage tank prevents the hydrophilic material inside from flowing out under atmospheric pressure. When the hydrophilic material inside the dipping tank is lower than the liquid outlet, the hydrophilic material inside the liquid storage tank flows out again, thus ensuring that the hydrophilic material inside the dipping tank always maintains a certain amount, realizing automatic feeding without the need for a power source, greatly reducing the feeding process for workers.

[0026] 3. The heating wire can heat the storage tank, and the heating wire is set inside the low wall of the bottom of the heating space. It can not only heat the inner cavity of the heating space, but also heat the hydrophilic material on the side of the storage tank near the outlet tank. The heating of the heating space can provide heat when drying aluminum foil, increase the drying speed, and improve the processing efficiency. The heating of the hydrophilic material can prevent the material from solidifying, which can greatly improve the utilization rate of resources.

[0027] 4. When aluminum foil needs to be installed, in order to improve installation efficiency, the user can push the lifting block up by the hydraulic cylinder. The lifting block drives the two extrusion rollers to slide inside the adjustment groove, thereby moving them away from the dipping roller. This makes it easier to pass the aluminum foil through the top of the dipping roller, improving installation efficiency. The height of the lifting block can also be adjusted according to the thickness of the aluminum foil and the required extrusion force, making it widely applicable. Attached Figure Description

[0053] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0054] This invention provides, for example Figure 1-14 An organic hydrophilic aluminum foil coating device is shown, comprising a liquid storage tank 1. A first side baffle 11 and a second side baffle 12 are fixedly connected to the front and rear sides of the liquid storage tank 1, respectively. A feeding roller 2, a feeding transfer roller 3, a supporting transfer roller 31, a discharging transfer roller 32, and a discharging assembly 4 are arranged between the first side baffle 11 and the second side baffle 12. The feeding transfer roller 3, the supporting transfer roller 31, and the discharging transfer roller 32 are positioned between the feeding roller 2 and the discharging assembly 4. A slot for placing the feeding transfer roller 3 is opened on the front side of the first side baffle 11 and the second side baffle 12, and the slot is inclined to the upper left. A dipping groove 6 is arranged below the feeding transfer roller 3 and the supporting transfer roller 31. A cleaning assembly 5 and a uniform coating assembly 7 are respectively arranged on the left and right sides of the dipping groove 6. The liquid storage tank 1... The interior is equipped with an L-shaped partition, which divides the liquid storage tank 1 into a liquid storage tank and a heating space 8. In use, the user places the prepared aluminum foil into the slot through the feeding roller 2. Then, the user starts the device so that the aluminum foil passes through the feeding roller 2, around the feeding transfer roller 3, and through the cleaning component 5. The cleaning component 5 cleans and wipes the surface of the aluminum foil to further ensure the cleanliness of the aluminum foil surface. The cleaned aluminum foil is dipped in the dipping tank 6, and the aluminum foil does not penetrate into the dipping tank 6 to prevent contamination of the other side of the aluminum foil. After the aluminum foil is dipped, it is evenly coated by the uniform coating component 7. The heat sealing blower inside the heating space 8 blows the aluminum foil surface for rapid drying. The dried aluminum foil is then wound and discharged by the support transfer roller 31 and the discharge transfer roller 32 and the discharge component 4.

[0055] The discharge assembly 4 includes a motor 41, an active pressure block 42, and a driven pressure block 43. An active rod 421 is fixedly connected to the output end of the motor 41. An adjusting cylinder 422 is rotatably connected to the outer side of the active rod 421 near the motor 41. The outer side of the adjusting cylinder 422 is threadedly connected to the inner side of the active pressure block 42 via internal and external threads. The driven pressure block 43 is symmetrical to the active pressure block 42. A driven rod 431 is fixedly connected inside the driven pressure block 43. A rotating roller 44 is disposed between the active pressure block 42 and the driven pressure block 43. A rotating handle 423 is fixedly connected to the outer side of the adjusting cylinder 422. When installing the discharge assembly 4, the user can rotate the roller... One end of roller 44 is inserted into the interior of driven pressure block 43, and the other end is aligned with driving pressure block 42. Then, by rotating handle 423, adjusting cylinder 422 is rotated. Adjusting cylinder 422 drives driving pressure block 42 to slide inward, so that driven pressure block 43 and driving pressure block 42 are fixed with rotating roller 44, which greatly improves installation efficiency. By starting motor 41, motor 41 drives rotating roller 44, driving pressure block 42 and driven pressure block 43 to rotate. Driven rod 431 and driving rod 421 are connected to first side baffle 11 and second side baffle 12 through bearings, so that rotating roller 44 rotates, thereby making rotating roller 44 wind up aluminum foil.

[0056] Furthermore, a dipping roller 61 is rotatably mounted inside the dipping tank 6. Squeezing rollers 64 are mounted on both sides above the dipping roller 61. A suction layer 62 is fixedly connected to the outer side of the dipping roller 61. Rotating cylinders 65 are rotatably connected to the outer sides of both squeezing rollers 64, and the rotating cylinders 65 contact the suction layer 62. A friction block 63 is mounted at the bottom of the dipping roller 61. Both ends of the friction block 63 are fixedly connected between the first side baffle 11 and the second side baffle 12. The friction block 63 is arc-shaped and contacts the suction layer 62. A friction groove is provided on the inner surface of the friction block 63. The friction block 63 does not contact the lower wall of the dipping tank 6, thus enabling the dipping roller to... The hydrophilic melt flows on both sides of the plate. An adjustment plate 9 is provided on the outside of the dipping tank 6. When dipping aluminum foil, the aluminum foil is between the dipping roller 61 and the extrusion roller 64. The dipping roller 61 rotates, which can absorb the coating material on its outer absorbent layer 62. Then, it passes through the friction block 63, which rubs the absorbent layer 62 to make it fully absorb the material. The dipping roller 61, which absorbs the material, is in full contact with the aluminum foil under the action of the extrusion roller 64, which greatly improves the coating effect. The rotating cylinder 65 on the outside of the extrusion roller 64 rotates with the movement of the aluminum foil, which can reduce the friction on the aluminum foil, reduce the running resistance of the device, and facilitate the operation of the device.

[0057] Heating wires are installed inside the low wall at the bottom of the heating space 8. Air inlets 86 are provided on both the front and rear sides of the heating space 8, and an air outlet 87 is provided on the top of the heating space 8. The air outlet 87 is vertically arranged and has a certain angle with the inclined aluminum foil, which can blow hot air from top to bottom. This not only dries the aluminum foil but also blows off excess hydrophilic material on the surface of the aluminum foil. A crossbar 84 is rotatably connected inside the heating space 8, and fan blades 85 are fixedly connected to both ends of the crossbar 84. The fan blades 85 are located inside the air inlets 86. The heating wires can heat the liquid storage tank 1. The heating wires are located inside the low wall at the bottom of the heating space 8. This not only heats the inner cavity of the heating space 8 but also heats the hydrophilic material on the side of the liquid storage tank near the liquid outlet 14. The heating of the heating space 8 can provide heat when drying the aluminum foil, increasing the drying speed. Heating the hydrophilic material can prevent the material from solidifying, which can greatly improve the utilization rate of resources.

[0058] The left side of the dipping tank 6 is fixedly connected to the fixed connecting plate 13, and the left side of the liquid storage tank 1 is inclined. The left and right sides of the dipping tank 6 are fixedly connected to the fixed connecting plate 13 and the liquid storage tank 1 respectively. The fixed connecting plate 13, the dipping tank 6 and the liquid storage tank 1 form a V-shaped groove, and the friction block 63 is located at the bottom of the V-shaped groove.

[0059] Specifically, the system ensures that the hydrophilic material inside the dipping tank 6 is always at the bottom of the tank, preventing splashing. Even if splashing occurs, the V-shaped groove structure allows it to automatically flow back to the bottom of the tank, preventing resource waste. The cleaning component 5 and the uniform coating component 7 are respectively located on both sides of the dipping tank 6 and are close to the squeezing rollers 64 on both sides of the dipping roller 61. This also prevents the molten hydrophilic material inside the tank from splashing due to the rotation of the dipping tank 6. The cleaning component 5 has a certain width, which prevents dust on the upper side from contacting the molten hydrophilic material on the lower side. The cooperation of all parts greatly improves the safety of the device.

[0060] In the structure, the cleaning component 5 is disposed between the feeding conveyor roller 3 and the dipping roller 61, and the top two sides of the cleaning component 5 are rounded. The bottom of the cleaning component 5 is fixedly connected to a sliding rod 51. The inner surface of the fixed connecting plate 13 is provided with a sliding groove 52 that cooperates with the sliding rod 51 for easy disassembly and installation. One end of the cleaning component 5 is fixedly connected to a first pull plate. The outer side of the first pull plate is provided with a handle. The pull plate is detachably connected to the first side baffle 11 by screws. The interior of the first side baffle 11 is provided with a through hole that cooperates with the cleaning component 5. The top surface of the cleaning component 5 protrudes from the connection surface between the top of the feeding conveyor roller 3 and the bottom of the left squeeze roller 64 of the dipping roller 61.

[0061] When in use, the top two sides of the cleaning component 5 are rounded to prevent damage to the aluminum foil. The cleaning component 5 can be pulled out of the device by the handle for easy replacement and cleaning. The sliding rod 51 at the bottom of the cleaning component 5 slides inside the sliding groove 52 to limit the position of the cleaning component 5.

[0062] The top of the uniform coating component 7 is rounded to prevent damage to the aluminum foil. The uniform coating component 7 is tilted on the upward side and its bottom is in close contact with the surface of the liquid storage tank 1. The top of the uniform coating component 7 is provided with an inner groove near the contact point. The inner groove is provided with a through hole. If water drips from the aluminum foil coating layer, the fan blade 85 can blow the excess hydrophilic material on the surface of the aluminum foil downwards, so that it can flow back into the dip trough 6 along the inner groove and through hole, preventing the accumulation of hydrophilic material on the top and affecting the uniformity of coating. The bottom of the uniform coating component 7 is fixedly connected to a limiting block 71. The surface of the liquid storage tank 1 is provided with a limiting groove 72 that matches the limiting block 71. One end of the uniform coating component 7 is fixedly connected to a second pull plate. The outer side of the second pull plate is provided with a handle. The pull plate is detachably connected to the first side baffle 11 by screws. The interior of the first side baffle 11 is provided with a through hole that matches the cleaning component 5.

[0063] Specifically, when the aluminum foil passes through the uniform coating component 7, the uniform coating component 7 presses the surface of the aluminum foil, making the internal hydrophilic material spread more evenly, and can scrape off excess hydrophilic material. The scraped material naturally flows back into the dip tank 6. Users can disassemble and clean it by pulling out the handle. The limiting block 71 at the bottom of the uniform coating component 7 cooperates with the limiting groove 72 to facilitate positioning.

[0064] In the structure, the top surface of the uniform coating component 7 protrudes from the connection surface between the bottom of the extrusion roller 64 on the right side of the dipping roller 61 and the top of the feeding conveyor roller 3, and the top of the supporting conveyor roller 31 protrudes from the connection surface between the uniform coating component 7 and the discharge conveyor roller 32; this ensures that the aluminum foil can fully contact the uniform coating component 7 after dipping.

[0065] Among them, a transmission belt 81 is provided on the outer side of the driven rod 431, and the other end of the transmission belt 81 is connected to the driving gear 82. The side of the driving gear 82 is meshed with the driven gear 83. The driven gear 83 is fixedly connected to the cross rod 84. The air outlet 87 is provided between the uniform coating component 7 and the support transfer roller 31.

[0066] Specifically, the driven rod 431 drives the driving gear 82 to rotate via the transmission belt 81. The driving gear 82 drives the crossbar 84 to rotate via the driven gear 83. Since the diameter of the driving gear 82 is larger than that of the driven gear 83, it can drive the fan blade 85 to rotate at high speed. The fan blade 85 allows the outside air to enter through the air inlet 86 and be heated through the heating space 8. Then, it is sprayed through the air outlet 87 onto the surface of the aluminum foil uniformly coated with hydrophilic material, which can accelerate the drying process and greatly improve the efficiency of the device. Moreover, the transmission setting helps to save power sources and process steps, greatly improving the processing efficiency.

[0067] In the structure, a liquid outlet 14 is provided at the bottom of the liquid storage tank near the dipping tank 6, and the top of the liquid outlet 14 is not higher than the central axis of the dipping roller 61. A liquid inlet is provided at the top of the liquid storage tank 1, and a sealing cover 17 is provided inside the liquid inlet. A transparent liquid level viewing table 16 is provided at the rear of the liquid storage tank 1 to facilitate observation of the material reserve inside the liquid storage tank 1.

[0068] Specifically, the inlet facilitates feeding settings, and the sealing cap 17 seals the storage tank 1. The hydrophilic material flows into the dipping tank 6 through the outlet trough 14. When the hydrophilic material in the dipping tank 6 exceeds the top of the outlet trough 14, the sealed storage tank 1 prevents the hydrophilic material from flowing out under atmospheric pressure. When the hydrophilic material in the dipping tank 6 is lower than the outlet trough 14, the hydrophilic material in the storage tank 1 flows out again, thus ensuring that the hydrophilic material in the dipping tank 6 always maintains a certain amount, achieving automatic feeding. The user adds material according to the data they see, preventing the material inside from falling below the top of the outlet trough 14. At this time, the material inside the dipping tank 6 will not flow back into the storage tank 1, preventing internal material contamination. Moreover, no power source is required, greatly reducing the feeding process for operators.

[0069] Two adjusting plates 9 are fixedly connected to the outer side of the first side baffle 11, and two uprights 91 are fixedly connected between the two adjusting plates 9. A hydraulic cylinder 92 is fixedly connected to the top of the bottom adjusting plate 9, and a lifting block 93 is fixedly connected to the top of the hydraulic cylinder 92. The uprights 91 pass through the lifting block 93 and are slidably connected to the lifting block 93 to facilitate limiting the lifting block 93. The inner side of the lifting block 93 is fixedly connected to two extrusion rollers 64. Adjustment grooves 94 that cooperate with the extrusion rollers 64 are opened inside the first side baffle 11 and the second side baffle 12.

[0070] Specifically, when aluminum foil needs to be installed, in order to improve installation efficiency, the user can push the lifting block 93 up through the hydraulic cylinder 92. The lifting block 93 drives the two extrusion rollers 64 to slide inside the adjustment groove 94, thereby moving them away from the dipping roller 61, making it easier to pass the aluminum foil through the top of the dipping roller 61, thus improving installation efficiency. The height of the lifting block 93 can be adjusted according to the thickness of the aluminum foil and the required extrusion force, making it widely applicable.
