Description

Technical Field

[0001] This invention belongs to the field of color aluminum coil processing technology, specifically relating to a high-efficiency coating device for color aluminum coil processing and its usage method. Background Technology

[0002] Colored aluminum coils, as the name suggests, are aluminum substrates whose surfaces have been painted and colored. Common types include fluorocarbon colored aluminum coils and polyester colored aluminum coils. They are widely used in aluminum composite panels, industrial plant roofs and walls, aluminum louvers, composite panels, aluminum ceilings, beverage cans, and electronic products. During their production, a coating device is used to coat the surface of the aluminum coil to protect it from damage and provide anti-oxidation and corrosion resistance. The colored aluminum coil is pre-treated and glue is applied to its surface. Then, a hot press roller presses the protective film onto the surface of the colored aluminum coil and melts the glue to achieve maximum adhesion, thus allowing the protective film to adhere to the colored aluminum coil.

[0003] In existing lamination equipment, the protective film is continuously applied to the surface of all the aluminum coils. At the rear end, there is a sliding blade to cut the aluminum coils and the protective film, forming aluminum coils of different sizes as needed. The cut aluminum coils have excess film edges with glue on them, which causes dust to adhere to the film edges, causing the film edges to lift up and resulting in poor adhesion of the entire film.

[0004] For example, Chinese Patent Publication No. CN214397439U discloses a coating device for producing heat-insulating and corrosion-resistant colored aluminum coils. It improves the coating effect of aluminum coils by heating and baking the coating film in an oven. However, it does not address the treatment of rough edges of the protective film at the cut points, which can easily cause the film edges at the cut points to lift up, resulting in poor adhesion of the entire film.

[0005] For example, Chinese Patent Publication No. CN113232283A discloses an aluminum profile surface coating device and coating method. The device cuts the film edge between two aluminum profiles downwards with a cutter, but does not provide any treatment for the film edge after cutting. If there are abnormalities on the film edge during cutting and they are not dealt with in time, dust may adhere to the film edge during transportation or storage, causing the film edge to lift up and resulting in poor adhesion of the entire film. Summary of the Invention

[0006] The purpose of this invention is to provide a high-efficiency coating device for processing colored aluminum coils, which can treat the cut film edges to prevent dust from adhering to the film edges and causing them to lift, thereby improving the adhesion of the film.

Therefore, the invention is not limited to the specific embodiments disclosed below.

[0049] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0050] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth. Example

[0051] Please see the appendix Figures 1 to 6 As shown, this is the first embodiment of the present invention. This embodiment provides a high-efficiency coating device for processing color aluminum coils, including a coating device body 1, an adjusting section 10, a transverse section 20, a preheating section 30, and an ironing section 40. A fixing frame 2 is installed on the coating device body 1 of the adjusting section 10. An electric push rod 3 is installed inside the fixing frame 2. A fixing plate 4 is installed at the output end of the electric push rod 3. The fixing plate 4 is slidably connected to the fixing frame 2. A cutting blade 5 is installed at the lower part of the fixing plate 4. A dividing blade 7 is installed at the lower part of the fixing plate 4 and near the cutting blade 5. A cutting tool is installed inside the fixing frame 2 and below the fixing plate 4. A platform 6 is installed at the lower end of the fixed plate 4 and near the cutting blade 5. The dividing blade 7 is located at the lower end of the adjusting part 10. The adjusting part 10 is used to adjust the film cutting distance between the dividing blade 7 and the cutting blade 5. A transverse moving part 20 is installed on the adjusting part 10. One end of the dividing blade 7 is connected to the transverse moving part 20. The transverse moving part 20 is used to drive the dividing blade 7 to move laterally. A preheating part 30 is installed on the fixed plate 4. One end of the preheating part 30 is connected to the adjusting part 10. The preheating part 30 is used to deliver hot air to the film cutting position. An ironing part 40 is installed on the adjusting part 10. The ironing part 40 is used to remove the rough edges at the film cutting position of the dividing blade 7.

[0052] Specifically, the aluminum coil is placed on the main body 1 of the coating device, and passed between the cutting blade 5 and the cutting table 6. Adhesive is applied to the aluminum coil, and the protective film is pressed onto the surface of the aluminum coil by the hot press rollers on the main body 1 of the coating device. The cutting distance between the cutting blade 5 and the dividing blade 7 is adjusted using the adjusting unit 10. The electric push rod 3 is activated, which moves the cutting blade 5 downward and closer to the aluminum coil. At the same time, the dividing blade 7 moves and contacts the protective film on the surface of the aluminum coil. The aluminum coil is then cut by the cutting blade 5. The process involves creating a rough cut edge, causing the transverse section 20 to move the dividing blade 7 laterally, dividing the film on the surface of the aluminum coil, separating the rough cut edge from the overall protective film, activating the preheating section 30 to heat the cutting position of the dividing blade 7 with hot air, and as the dividing blade 7 approaches the film on the surface of the aluminum coil, the ironing section 40 contacts the film on the surface of the aluminum coil, causing the aluminum coil to roll, activating the ironing section 40, and allowing the cutting position to pass through the ironing section 40. The ironing section 40 processes the cutting position and adheres the cutting edge and rough edge to the aluminum coil.

[0053] In a preferred embodiment, please refer to Figures 5 to 7 The adjustable section 10 includes a motor 11, a screw a12, a fixing strip 13, a fixing rod 14, a limiting rod 15, a limiting block 16, a support strip 17, and a spring a18. The motor 11 is fixed to the lower end of the fixing plate 4. The screw a12 is fixed to the output end of the motor 11, and the end of the screw a12 away from the motor 11 is rotatably connected to the cutting blade 5. The fixing rod 14 is fixed to the lower end of the fixing plate 4, and the end of the fixing rod 14 away from the fixing plate 4 is fixedly connected to the cutting blade 5. The fixing strip 13 is slidably connected to the outside of the fixing rod 14, and the fixing strip 13 is threadedly connected to the screw a12. The limiting rod 15 is slidably connected to the inside of the fixing strip 13. The limiting block 16 is fixed to the upper end of the limiting rod 15. The support strip 17 is fixed to the lower end of the limiting rod 15. The spring a18 is disposed on the outside of the limiting rod 15 and located between the fixing strip 13 and the support strip 17. The dividing blade 7 is disposed at the lower end of the support strip 17.

[0054] It should be noted that a transverse through groove is provided inside the fixing plate 4 and above the limiting block 16, so that when the position of the limiting block 16 changes, the fixing plate 4 will not block the limiting block 16 from moving upward, thus ensuring the normal movement of the limiting rod 15.

[0055] In this embodiment, when adjusting the cutting distance between the cutting blade 5 and the dividing blade 7, the motor 11 is started, driving the screw a12 to rotate. Because the screw a12 is threadedly connected to the fixing strip 13, the fixing strip 13 moves on the surface of the fixing rod 14, thereby driving the dividing blade 7 to move and changing the distance between the dividing blade 7 and the cutting blade 5. When the cutting blade 5 cuts the color aluminum coil, a burr edge is formed. By changing the distance between the cutting blade 5 and the dividing blade 7, the width of the protective film separated from the cut edge is changed, which can be adjusted according to different types of protective film. Alternatively, the spacing can be changed to improve adaptability. When the electric push rod 3 moves the fixing plate 4 downward and brings the dividing blade 7 close to the aluminum coil, the electric push rod 3 continues to push the fixing plate 4 downward when the dividing blade 7 contacts the protective film on the aluminum coil. This causes the limiting rod 15 to move inside the fixing strip 13, thereby compressing the spring a18 and generating elastic force. Through the elastic force of the spring a18, a downward force is generated on the dividing blade 7, which in turn makes the dividing blade 7 come into close contact with the protective film on the aluminum coil, making it easier for the dividing blade 7 to divide the protective film on the aluminum coil.

[0056] Secondly, please refer to it again. Figures 5 to 8 The transverse movement part 20 includes a limiting rod 21, an iron block 22, a limiting block 23, a spring b24, an electromagnet 25, and a slider 26. The limiting rod 21 is fixed to one end of the support bar 17, the limiting block 23 is fixed to the end of the limiting rod 21 away from the support bar 17, the iron block 22 is slidably connected to the outside of the limiting rod 21, the spring b24 is disposed on the outside of the limiting rod 21 and located between the support bar 17 and the iron block 22, the electromagnet 25 is fixed to the end of the support bar 17 near the iron block 22, the slider 26 is fixed to the upper end of the dividing blade 7, and a groove matching the slider 26 is provided at the lower end of the support bar 17. The dividing blade 7 is slidably connected to the support bar 17 through the cooperation of the slider 26 and the groove, and the iron block 22 is fixedly connected to the slider 26.

[0057] It should be noted that the attractive force between the electromagnet 25 and the iron block 22 is greater than the elastic force of the spring b24, thus reducing the resistance caused by the spring b24 when the electromagnet 25 attracts the iron block 22 to move.

[0058] As described above, when dividing the protective film on the aluminum coil, the electromagnet 25 is activated, causing it to attract the iron block 22 towards it. This compresses the spring b24, generating elastic force, which in turn drives the dividing blade 7 to move laterally, dividing the protective film on the aluminum coil. This results in a partial strip of protective film separating from the overall protective film at the cut edge. This process prevents the overall protective film from separating from the aluminum coil when the protective film at the cut edge separates from it, thus improving the bond between the protective film and the aluminum coil. By stopping the power supply to the electromagnet 25, the spring force of the spring b24 allows the dividing blade 7 to return to its original position, facilitating the next division of the protective film on the aluminum coil by the dividing blade 7.

[0059] Secondly, please refer to the following as well. Figure 5 , Figure 6 and Figure 9 The preheating section 30 includes a fan 31, a heating chamber 32, a heating wire 33, and a connecting pipe 34. The fan 31 is fixed to the upper end of the fixing plate 4, the heating chamber 32 is fixed to the output end of the fan 31, the heating wire 33 is disposed inside the heating chamber 32, the connecting pipe 34 is fixed to the end of the heating chamber 32 away from the fan 31, and the end of the heating chamber 32 away from the fan 31 is fixed to the upper end of the limiting block 16. The limiting rod 15, the limiting block 16, and the support bar 17 are all hollow structures.

[0060] It should be noted that the input end of the fan 31 is equipped with a filter screen, which can filter impurities in the air and prevent them from entering the interior of the fan 31, thus ensuring the airflow of the connecting pipe 34.

[0061] It is worth mentioning that the heating chamber 32 is connected to the limiting block 16, the limiting rod 15 and the support bar 17 through the connecting pipe 34, so as to ensure that the hot gas inside the heating chamber 32 is discharged through the support bar 17.

[0062] As described above, when heating the film cutting area, the fan 31 is started to allow external air to enter the interior of the heating chamber 32, and the air is heated by the heating wire 33. The heated gas passes through the connecting pipe 34, the limiting block 16 and the limiting rod 15, enters the interior of the support bar 17, and is then discharged through the support bar 17, thus performing preheating treatment on the film cutting area to ensure subsequent processing of the film cutting area.

[0063] Secondly, please refer to the following as well. Figure 5 , Figure 6 and Figure 10The ironing unit 40 includes a connecting block 41, a connecting rod 42, a stop block 43, a connecting strip 44, a spring c45, a heating plate 46, a cleaning cotton 47, and an electronic control unit 50. The connecting block 41 is fixed to the lower end of the fixing strip 13 and away from the cutting blade 5. The connecting rod 42 is slidably connected inside the connecting block 41. The stop block 43 is fixed to the upper end of the connecting rod 42. The connecting strip 44 is fixed to the lower end of the connecting rod 42. The spring c45 is disposed on the outside of the connecting rod 42 and located between the connecting block 41 and the connecting strip 44. The heating plate 46 is fixed to the lower end of the connecting strip 44 and away from the cutting blade 5. The cleaning cotton 47 is fixed to the lower end of the connecting strip 44 and close to the cutting blade 5.

[0064] It should be noted that a heat insulation layer is provided between the heating plate 46 and the cleaning cotton 47, which can reduce the impact of the high temperature of the heating plate 46 on the service life of the cleaning cotton 47.

[0065] As described above, while the electric push rod 3 drives the fixed plate 4 to move downward, the heating plate 46 and the cleaning cotton 47 first come into contact with the colored aluminum roll. The electric push rod 3 continues to drive the fixed plate 4 to move downward, causing the connecting rod 42 to slide inside the connecting block 41. At the same time, the electric control unit 50 controls the operation of the heating plate 46 and compresses the spring c45. When the spring c45 is compressed, it generates elastic force. Through the elastic force of the spring c45, a downward force is generated on the connecting strip 44, thereby making the heating plate 46 and the cleaning cotton 47 in close contact with the protective film on the colored aluminum roll. This ensures that the cut film area is treated, prevents dust from adhering to the film edge and causing the film edge to lift, and improves the adhesion of the film.

[0066] Please refer to the following: Figure 5 , Figure 10 and Figure 11 The electrical control unit 50 includes a screw b51, a knob 52, a connecting slider 53, two conductive contacts 54, two elastic wires 55, two conductive contacts 56, and two compression springs 57. The screw b51 is rotatably connected to the inside of the connecting rod 42. The knob 52 is fixed to the upper end of the screw b51. The connecting slider 53 is threaded to the outside of the screw b51 and slidably connected to the inside of the connecting rod 42. The two conductive contacts 54 are both fixed to the outside of the connecting slider 53 and slidably connected to the connecting rod 42. The two elastic wires 55 are both fixed to the inside of the connecting rod 42 and are electrically connected to the two conductive contacts 54 respectively. The two elastic wires 55 are both electrically connected to the heating plate 46. The two conductive contacts 56 are both slidably connected to the inside of the connecting block 41 and are located directly above the two conductive contacts 54 respectively. The two compression springs 57 are both located inside the connecting block 41 and are located close to the positions of the two conductive contacts 56 respectively.

[0067] It should be noted that the conductive contact 56 is connected to the power supply module inside the main body 1 of the coating device, so that the conductive contact 56 is powered.

[0068] As described above, when adjusting the starting range of the heating plate 46, rotating the knob 52 causes the connecting slider 53 and the conductive contact 54 to move inside the connecting rod 42. Depending on the usage requirements, the position of the conductive contact 54 inside the connecting rod 42 is adjusted. The electric push rod 3 drives the fixing plate 4 downwards, causing the connecting rod 42 to move upwards inside the connecting block 41. This causes the conductive contact 54 to gradually move upwards and approach the conductive contact 56. When the conductive contact 56 contacts the conductive contact 54, the conductive contact 56 receives a reaction force from the conductive contact 54, causing the conductive contact 56 to move into the connecting block 41. This compresses the spring 57, generating elastic force that pushes the conductive contact 56 closer to the conductive contact 56. The contact piece 54 allows the conductive contact 56 to make close contact with the conductive contact piece 54. When the conductive contact 56 and the conductive contact piece 54 are in contact, the conductive contact 56, the conductive contact piece 54 and the elastic wire 55 supply power to the heating plate 46, causing the heating plate 46 to heat up and make the aluminum roll roll. This causes the heating plate 46 and the cleaning cotton 47 to slide relative to each other on the aluminum roll. When the cleaning cotton 47 slides, it wipes and cleans the impurities adhering to the surface of the film cutting area. When the heating plate 46 passes the film cutting area, the high temperature of the heating plate 46 irons the film cutting area and makes the cut edge and rough edge adhere to the aluminum roll, preventing dust from adhering to the film edge and causing the film edge to lift, thus improving the adhesion of the film.

[0069] Implementation of Column 2

[0070] This invention also discloses a method for using a high-efficiency coating device for processing color aluminum coils, specifically including the following steps:

[0071] Step 1: Place the aluminum coil on the coating device, apply glue to the aluminum coil, and press the protective film onto the surface of the aluminum coil using hot rollers;

[0072] Step 2: Use the adjusting unit 10 to adjust the film cutting distance between the cutting blade 5 and the dividing blade 7, start the electric push rod 3 to make the cutting blade 5 cut the color aluminum coil, and make the transverse moving unit 20 drive the dividing blade 7 to move laterally to divide the film on the surface of the color aluminum coil.

[0073] Step 3: Start the preheating unit 30 to heat the cutting position of the dividing blade 7 by supplying hot air, start the ironing unit 40 to heat, make the colored aluminum roll roll, and make the cutting position pass through the ironing unit 40. The ironing unit 40 processes the cutting position and makes the rough edges adhere to the colored aluminum roll.

[0074] The working principle of this invention is as follows: A colored aluminum coil is placed on the main body 1 of the coating device, and the coil passes between the cutting blade 5 and the cutting table 6. Adhesive is applied to the coil, and the protective film is pressed onto the surface of the coil by the hot press rollers on the main body 1 of the coating device. The cutting distance between the cutting blade 5 and the dividing blade 7 is adjusted using the adjusting unit 10. The electric push rod 3 is activated, causing the cutting blade 5 to move downwards and closer to the colored aluminum coil. Simultaneously, the dividing blade 7 moves and contacts the protective film on the surface of the colored aluminum coil. The cutting blade 5 then cuts the colored aluminum coil. The cutting process involves the transverse section 20 moving the dividing blade 7 laterally to cut the film on the surface of the aluminum coil. The preheating section 30 is activated to heat the cutting position of the dividing blade 7 with hot air. As the dividing blade 7 approaches the film on the surface of the aluminum coil, the ironing section 40 is activated, causing the aluminum coil to roll so that the cutting position passes through the ironing section 40. The ironing section 40 processes the cutting position and adheres the rough edges to the aluminum coil, preventing dust from adhering to the film edge and causing it to lift, thus improving the adhesion of the film.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
