Description

Technical Field

[0001] This invention belongs to the field of film condensation technology, specifically relating to film condensation equipment and process for aluminum profiles. Background Technology

[0002] Currently, high-end home decoration, doors and windows, and curtain wall aluminum profiles generally adopt PVC film coating technology for surface decoration modification, replacing traditional spraying and anodizing processes. It has advantages such as rich colors, realistic textures, high cost performance, and good renovation. It is the mainstream processing method for high-end aluminum profile finishes. Existing improved processes mostly only optimize adhesive formulas or coating temperatures, without innovating the substrate interface structure and intermediate transition layer system. They cannot fundamentally solve the core problems of poor adhesion, weather resistance, and texture. The industry urgently needs a new composite condensation film coating process to solve the above-mentioned technical pain points.

[0003] Patent CN114408268A discloses a coating equipment for aluminum profile products. This equipment includes a frame and a profile conveying mechanism, a coating mechanism, and a pressing mechanism mounted on the frame. The coating mechanism includes a fixed support, a lifting device, and two unwinding devices. The fixed support has a first linear slide rail along a first direction. The lifting device includes a lifting support slidably mounted on the first linear slide rail and a first driving component that drives the lifting support to slide along the first direction. The lifting support has a second linear slide rail along a second direction. The two unwinding devices each include an unwinding component slidably mounted on the second linear slide rail and a second driving component that drives the unwinding component to slide along the second direction. The unwinding component has a protective film, and the outer surface of the protective film has an adhesive portion. This aluminum profile coating equipment can change the protective film roll without stopping the machine, simplifying operation and improving production efficiency.

[0004] The above-mentioned device also has the following problems: when the above-mentioned device is used to solidify the workpiece, it is difficult to make the workpiece fully solidify, resulting in low adhesion of the subsequent coating, which makes the subsequent coating easy to fall off, thereby affecting the quality of the subsequent coating and reducing production efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide aluminum profile condensation equipment and condensation process to solve the problem of insufficient contact between aluminum profiles and liquids during the condensation process.

[0006] To achieve the above objectives, the present invention provides an aluminum profile film-forming device, comprising: an immersion tank, wherein an isolation plate is provided inside the immersion tank; an installation frame is provided on the immersion tank; an electric telescopic rod is provided on the inner wall of the installation frame; a drainage device is provided at the front of the immersion tank; an auxiliary mechanism is provided at the top of the immersion tank; a cleaning mechanism is provided on the inner wall of the auxiliary mechanism; a connecting frame is fixedly connected to the telescopic end of the electric telescopic rod; a fixing block is fixedly connected to the left side of the connecting frame; a pressure plate is rotatably connected to the inner wall of the fixing block via a torsion spring; an electric limiting device is provided at the top of the fixing block; an elastic telescopic rod is fixedly connected to the inner wall of the immersion tank; a placement plate is fixedly connected to the telescopic end of the elastic telescopic rod; an inclined plate is slidably connected to the inner wall of the placement plate; and a drainage device is provided at the rear of the immersion tank. A water pump is fixedly connected, with a connecting pipe 1 fixedly connected to the top of the water pump and a connecting pipe 2 fixedly connected to the bottom of the water pump. A spray plate 1 is fixedly connected to the inner wall of the immersion tank, and a spray plate 2 is fixedly connected to the bottom of the spray plate 1. The aluminum profile blank can move up and down in the low-chromium environmentally friendly chromating liquid chamber of the immersion tank, which allows the low-chromium environmentally friendly chromating liquid to come into more thorough contact with the aluminum profile blank. As a result, a uniform and dense chromium passivation film can be generated on the surface of the aluminum profile blank, which can significantly improve the adhesion of the aluminum profile blank and improve the quality and efficiency of the aluminum profile blank in the subsequent film solidification process. It can enable a 20μm precise transparent film layer to fill the micropores of the aluminum material and level the surface of the substrate. The hot melt adhesive can completely and uniformly wet the interface, and the film bonding strength is increased by more than 80%, completely eliminating delamination and peeling problems.

[0007] According to the above technical solution, the electric limiting device is located above the pressure plate and is used to limit the pressure plate. The water pump is connected to the connecting pipe 1, and the spray plate 1 and spray plate 2 can spray out the low-chromium environmentally friendly chromating liquid. At this time, the low-chromium environmentally friendly chromating liquid can be sprayed onto the aluminum profile blank, which can accelerate the speed of the low-chromium environmentally friendly chromating liquid adhering to the aluminum profile blank and improve the subsequent film solidification speed and efficiency.

[0008] According to the above technical solution, the first connecting pipe is connected to the first spray plate, the second connecting pipe is connected to the water pump, and the second connecting pipe is connected to the immersion tank. After the aluminum profile blank is pushed by the pressure plate, the aluminum profile blank will be located between the first spray plate and the second spray plate. At this time, the water pump will start, and the water pump can discharge the low-chromium environmentally friendly chromating liquid in the immersion tank cavity into the first connecting pipe through the second connecting pipe.

[0009] According to the above technical solution, the auxiliary mechanism includes a support block, which is fixedly connected to the inner wall of the immersion tank. A fixed rod is fixedly connected to the immersion tank, and a motor is fixedly connected to the right side of the fixed rod. A reciprocating screw is rotatably connected to the inner wall of the fixed rod, and a movable frame is movably connected to the circumferential surface of the reciprocating screw. A fan is fixedly connected to the top of the movable frame, and an exhaust plate is fixedly connected to the bottom of the movable frame. A fixed air pipe is fixedly connected to the bottom of the fan. The fan can exhaust air into the exhaust plate through the fixed air pipe. At this time, during the movement of the exhaust plate, the exhaust plate can simultaneously exhaust air to the surface of the aluminum profile blank, which can blow away excess low-chromium environmentally friendly chromating liquid on the aluminum profile blank, and at the same time, can make the low-chromium environmentally friendly chromating liquid adhere more fully to the surface of the aluminum profile blank.

[0010] According to the above technical solution, the auxiliary mechanism also includes a fixed cover, which is fixedly connected to the top of the pressure plate. A rotating column is rotatably connected to the inner wall of the fixed cover. A spiral oblique plate is fixedly connected to the circumferential surface of the rotating column, and a connecting groove plate is fixedly connected to the circumferential surface of the rotating column. This allows the low-chromium environmentally friendly chromating liquid in the pressing area of ​​the pressure plate to be moved, avoiding insufficient contact between the surface of the aluminum profile blank and the low-chromium environmentally friendly chromating liquid due to the pressure plate limiting and pushing point. This ensures that the surface of the aluminum profile blank can be fully coated with the low-chromium environmentally friendly chromating liquid, thereby improving the subsequent film condensation quality of the device.

[0011] According to the above technical solution, the fixed air pipe is connected to the exhaust plate, the exhaust plate is located above the support block, the fixed cover is provided with a liquid inlet hole, and the liquid inlet hole is used to allow the low-chromium environmentally friendly chromating liquid to enter the fixed cover. The movable frame is slidably connected to the inner wall of the immersion tank. The movement of the pressure plate will drive the fixed cover to move downward synchronously. The movement of the fixed cover will drive the rotating column to move synchronously. The synchronous movement of the rotating column will drive the spiral blade to move.

[0012] According to the above technical solution, the cleaning mechanism includes a connecting block, which is fixedly connected to the inner wall of the movable frame. A second mounting frame is fixedly connected to the inner wall of the connecting block, and a second rotating column is rotatably connected to the inner wall of the second mounting frame. A first sponge pressing column is fixedly connected to the circumferential surface of the second rotating column. The first sponge pressing column can generate a moving friction force due to contact with the aluminum profile blank plate. At this time, the first sponge pressing column can rotate and press and spread the chromium environmentally friendly chromating liquid on the upper and lower sides of the aluminum profile blank plate evenly, ensuring that the four corners of the aluminum profile blank plate can be fully adhered to the chromium environmentally friendly chromating liquid.

[0013] According to the above technical solution, the cleaning mechanism also includes a rotating column three, which is rotatably connected to the inner wall of the mounting frame two. A sponge pressure column two is fixedly connected to the circumferential surface of the rotating column three. The sponge pressure column two can thoroughly adhere the environmentally friendly chromating liquid to the side of the aluminum profile blank plate, ensuring the subsequent production quality and efficiency of the device.

[0014] According to the above technical solution, there are two sponge pressure columns on the second mounting frame, and the two sponge pressure columns are symmetrically distributed on the inner wall of the second mounting frame. During the movement of the second mounting frame, the movement of the second mounting frame will drive the rotating column three to move synchronously. During the movement of the rotating column three, the movement of the rotating column three will drive the sponge pressure columns two to move.

[0015] A process for an aluminum profile condensation film equipment includes the following steps: Step 1: Substrate pretreatment. Select the extruded aluminum profile blank and perform degreasing, dust removal, grinding and leveling treatment on the surface of the blank to remove surface oxide scale, oil stains and impurities, and ensure that the surface cleanliness of the substrate meets the standards. Step 2: Chromium passivation treatment. The pre-treated aluminum profile blank is sent to the chromium treatment production line for environmentally friendly chemical chromium passivation. A dense and uniform chromium passivation film is generated on the surface of the aluminum profile, which seals the active micropores on the surface of the aluminum material, improves the anti-corrosion performance of the substrate and the adhesion of subsequent coatings. The aluminum profile blank then needs to be subjected to chromium passivation treatment. Step 3: Precise transparent film spraying. Electrostatic spraying of a transparent protective coating is performed on the surface of the chromated aluminum profile. The spraying process parameters are strictly controlled to ensure that the dry film thickness of the transparent coating is precisely controlled to 20μm. After curing at room temperature, a dense and smooth film transition layer is formed. Step 4: Hot glue coating treatment. Italian mixed oil textured PVC decorative film is selected. High temperature hot glue coating process is used to tightly adhere the PVC film to the surface of the cured transparent condensed film. The adhesive layer is fully penetrated and bonded by hot pressing, realizing the integrated composite of film layer, condensed film and aluminum substrate. Shaping and curing are carried out. After the coating is completed, constant temperature cooling and shaping are carried out and static curing is carried out to remove internal stress, and the finished condensed film coated aluminum profile is obtained.

[0016] The beneficial effects of this invention are: 1. This aluminum profile coagulation film equipment, through the coordinated movement of the immersion tank, isolation plate, mounting frame one, electric telescopic rod, drainage device, connecting frame, fixing block, pressure plate, electric limit device, elastic telescopic rod, placement plate, inclined plate, water pump, connecting pipe one, connecting pipe two, spray plate one, and spray plate two, allows the aluminum profile blank to move up and down within the low-chromium environmentally friendly chromating liquid chamber of the immersion tank. This ensures more thorough contact between the low-chromium environmentally friendly chromating liquid and the aluminum profile blank, resulting in the formation of a uniform and dense chromated passivation film on the surface of the aluminum profile blank. This significantly improves the adhesion of the aluminum profile blank and enhances the quality and efficiency of the subsequent coagulation film process. Spray plates one and two spray the low-chromium environmentally friendly chromating liquid onto the aluminum profile blank, accelerating the adhesion of the low-chromium environmentally friendly chromating liquid and improving the subsequent coagulation speed and efficiency.

[0017] 2. This aluminum profile condensation film equipment, through the coordinated movement of support blocks, fixed rods, motors, reciprocating screws, moving frames, fans, exhaust plates, fixed air pipes, fixed covers, rotating columns, spiral blades, and connecting grooves, enables the fan to discharge air into the exhaust plate through the fixed air pipes. During the movement of the exhaust plate, it simultaneously discharges air onto the surface of the aluminum profile blank, dispersing excess low-chromium environmentally friendly chromating liquid. This also ensures more comprehensive adhesion of the low-chromium environmentally friendly chromating liquid to the surface of the aluminum profile blank, and allows the low-chromium environmentally friendly chromating liquid in the pressing area of ​​the pressure plate to be moved, preventing insufficient contact between the aluminum profile blank surface and the low-chromium environmentally friendly chromating liquid due to the pressure plate's limiting and pushing action. This ensures that the surface of the aluminum profile blank is fully coated with the low-chromium environmentally friendly chromating liquid, improving the subsequent condensation film quality of the device.

[0018] 3. This aluminum profile condensation film equipment, through the coordinated movement of the connecting block, mounting frame two, rotating column two, sponge pressure column one, rotating column three, and sponge pressure column two, can press and spread the environmentally friendly chromating liquid on the upper and lower sides of the aluminum profile blank plate, ensuring that the four corners of the aluminum profile blank plate can be fully adhered to the environmentally friendly chromating liquid. The sponge pressure column two can fully adhere the environmentally friendly chromating liquid to the sides of the aluminum profile blank plate, ensuring the subsequent production quality and efficiency of the equipment.

[0021] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0022] Example 1, as Figures 1-10As shown, an aluminum profile condensation film equipment includes: an immersion tank 1, an isolation plate 2 disposed inside the immersion tank 1, an installation frame 3 disposed on the immersion tank 1, an electric telescopic rod 4 disposed on the inner wall of the installation frame 3, a drainage device 5 disposed at the front of the immersion tank 1, an auxiliary mechanism 6 disposed at the top of the immersion tank 1, a cleaning mechanism 7 disposed on the inner wall of the auxiliary mechanism 6, a connecting frame 8 fixedly connected to the telescopic end of the electric telescopic rod 4, a fixing block 9 fixedly connected to the left side of the connecting frame 8, and a pressure plate 10 rotatably connected to the inner wall of the fixing block 9 via a torsion spring. An electric limit device 11 is provided on the top of the fixed block 9. An elastic telescopic rod 12 is fixedly connected to the inner wall of the immersion pool 1. A placement plate 13 is fixedly connected to the telescopic end of the elastic telescopic rod 12. An inclined plate 14 is slidably connected to the inner wall of the placement plate 13. A water pump 15 is fixedly connected to the rear of the immersion pool 1. A connecting pipe 16 is fixedly connected to the top of the water pump 15. A connecting pipe 2 17 is fixedly connected to the bottom of the water pump 15. A spray plate 18 is fixedly connected to the inner wall of the immersion pool 1. A spray plate 2 19 is fixedly connected to the bottom of the spray plate 18. When the device is preparing to apply a film to aluminum profiles, it sequentially undergoes substrate pretreatment, chromating passivation treatment, precise transparent film spraying, hot glue coating, and shaping and curing. The substrate pretreatment step involves first degreasing, dust removal, and grinding to smooth the surface of the extruded aluminum profile blank, removing oxide scale, oil, and impurities to ensure the substrate surface cleanliness meets standards. Next, the aluminum profile blank undergoes chromating passivation treatment. At this stage, the pretreated aluminum profile blank is moved above the immersion tank 1 using a suspended crane, ensuring the aluminum profile blank is positioned inside the immersion tank 1. Prior to this, the low-chromium environmentally friendly chromating agent needs to be drained through the drainage device 5. The liquid is discharged into the left chamber of the immersion tank 1. After the aluminum profile blank is placed in the immersion tank 1, it can be immersed in the low-chromium environmentally friendly chromating solution. Then, the electric telescopic rod 4 will be synchronously started by the electrical signal released by the operator's start control switch. The telescopic end of the electric telescopic rod 4 will drive the connecting frame 8 to move downward. The movement of the connecting frame 8 will drive the fixed block 9 to move. When the aluminum profile blank is placed in the cavity of the immersion tank 1, it can be positioned on the placement plate 13. The aluminum profile blank can be reverse-pressed by the inclined surface of the inclined plate 14 and pushed to move the inclined plate 14 until the plane of the inclined plate 14 contacts the two sides of the aluminum profile blank. At this time, the inclined plate 14 can press the aluminum profile blank against the inclined surface. The aluminum profile blank is moved and limited. Before the aluminum profile blank enters the immersion tank 1 cavity, the electric limiting device 11 does not activate and cannot rotate the pressure plate 10. This continues until the aluminum profile blank is below the pressure plate 10. As the connecting frame 8 moves downwards, the movement of the connecting frame 8 causes the fixed block 9 to move, which in turn moves the pressure plate 10. Simultaneously, the movement of the fixed block 9 also moves the electric limiting device 11, which then activates and rotates the pressure plate 10. After moving downwards a certain distance, the pressure plate 10 contacts the aluminum profile blank and presses it down. At this point, the aluminum profile blank... The aluminum profile blank can move up and down in the low-chromium environmentally friendly chromating liquid chamber of the immersion pool 1 through the extension and retraction of the electric telescopic rod 4 and the elastic reset characteristics of the elastic telescopic rod 12. This allows the aluminum profile blank to have more sufficient contact with the low-chromium environmentally friendly chromating liquid and the aluminum profile blank, thereby generating a uniform and dense chromating passivation film on the surface of the aluminum profile blank. This significantly improves the adhesion of the aluminum profile blank and enhances the quality and efficiency of the aluminum profile blank in the subsequent film solidification process. It enables the 20μm precise transparent film layer to fill the micropores of the aluminum material and level the surface of the substrate. The hot melt adhesive can completely and uniformly wet the interface, and the film bonding strength is increased by more than 80%, completely eliminating the problems of delamination and peeling. The electric limit device 11 is located above the pressure plate 10 and is used to limit the pressure plate 10. The water pump 15 is connected to the first connecting pipe 16, the first connecting pipe 16 is connected to the first spray plate 18, the second connecting pipe 17 is connected to the water pump 15, and the second connecting pipe 17 is connected to the immersion tank 1. When the device is in use, after the aluminum profile blank is pushed by the pressure plate 10, the aluminum profile blank will be located between the spray plate 18 and the spray plate 19. At this time, the water pump 15 will start. The water pump 15 can discharge the low-chromium environmentally friendly chromating liquid immersed in the pool 1 cavity into the connecting pipe 16 through the connecting pipe 17. The low-chromium environmentally friendly chromating liquid in the connecting pipe 16 can enter the spray plate 18 and the spray plate 19 in sequence. The spray plate 18 and the spray plate 19 can spray out the low-chromium environmentally friendly chromating liquid. At this time, the low-chromium environmentally friendly chromating liquid can be sprayed onto the aluminum profile blank, which can accelerate the speed of the low-chromium environmentally friendly chromating liquid adhering to the aluminum profile blank and improve the subsequent film solidification speed and efficiency. A process for an aluminum profile condensation film equipment includes the following steps: Step 1: Substrate pretreatment. Select the extruded aluminum profile blank and perform degreasing, dust removal, grinding and leveling treatment on the surface of the blank to remove surface oxide scale, oil stains and impurities, and ensure that the surface cleanliness of the substrate meets the standards. Step 2: Chromium passivation treatment. The pre-treated aluminum profile blank is sent to the chromium treatment production line for environmentally friendly chemical chromium passivation. A dense and uniform chromium passivation film is generated on the surface of the aluminum profile, which seals the active micropores on the surface of the aluminum material, improves the anti-corrosion performance of the substrate and the adhesion of subsequent coatings. The aluminum profile blank then needs to be subjected to chromium passivation treatment. Step 3: Precise transparent film spraying. Electrostatic spraying of a transparent protective coating is performed on the surface of the chromated aluminum profile. The spraying process parameters are strictly controlled to ensure that the dry film thickness of the transparent coating is precisely controlled to 20μm. After curing at room temperature, a dense and smooth film transition layer is formed. Step 4: Hot glue coating treatment. Italian mixed oil textured PVC decorative film is selected. High temperature hot glue coating process is used to tightly adhere the PVC film to the surface of the cured transparent condensed film. The adhesive layer is fully penetrated and bonded by hot pressing, realizing the integrated composite of film layer, condensed film and aluminum substrate. Shaping and curing are carried out. After the coating is completed, constant temperature cooling and shaping are carried out and static curing is carried out to remove internal stress, and the finished condensed film coated aluminum profile is obtained.

[0023] Overall working principle: The aluminum profile blank can move up and down in the low-chromium environmentally friendly chromating liquid chamber of immersion tank 1, which allows the low-chromium environmentally friendly chromating liquid to come into more thorough contact with the aluminum profile blank. As a result, a uniform and dense chromium passivation film can be formed on the surface of the aluminum profile blank, which can significantly improve the adhesion of the aluminum profile blank.

[0024] Example 2, as Figures 1-10As shown, based on Embodiment 1, the auxiliary mechanism 6 includes a support block 601, which is fixedly connected to the inner wall of the immersion tank 1. A fixed rod 602 is fixedly connected to the immersion tank 1. A motor 603 is fixedly connected to the right side of the fixed rod 602. A reciprocating screw 604 is rotatably connected to the inner wall of the fixed rod 602. A movable frame 605 is movably connected to the circumferential surface of the reciprocating screw 604. A fan 606 is fixedly connected to the top of the movable frame 605. An exhaust plate 607 is fixedly connected to the bottom of the movable frame 605. A fixed air pipe 608 is fixedly connected to the bottom of the fan 606. When the aluminum profile blank is immersed in the low-chromium environmentally friendly chromizing solution for 8 to 15 minutes, it is then moved to the upper right chamber of the immersion tank 1 using a suspended crane. At this time, the motor 603 starts, and the output end of the motor 603 drives the reciprocating screw 604 to move. The rotation of the reciprocating screw 604 drives the moving frame 605 to move. The moving frame 605 is immersed in the immersion tank 1. During the rotation of the reciprocating screw 604, the moving frame 605 can only move laterally through the reciprocating groove on the surface of the reciprocating screw 604. The movement of the moving frame 605 drives the fan 606 to enter the immersion tank. The movement of the moving frame 605 will drive the exhaust plate 607 to move. During the movement of the fan 606, the fan 606 will also drive the fixed air pipe 608 to move. At this time, the fan 606 can start synchronously during the movement of the fan 606. The fan 606 can exhaust air into the exhaust plate 607 through the fixed air pipe 608. At this time, during the movement of the exhaust plate 607, the exhaust plate 607 can simultaneously exhaust air to the surface of the aluminum profile blank, which can blow away the excess low-chromium environmentally friendly chromating liquid on the aluminum profile blank, and at the same time, can make the low-chromium environmentally friendly chromating liquid adhere more fully to the surface of the aluminum profile blank. The auxiliary mechanism 6 also includes a fixed cover 609, which is fixedly connected to the top of the pressure plate 10. A rotating column 610 is rotatably connected to the inner wall of the fixed cover 609. A spiral inclined plate 611 is fixedly connected to the circumferential surface of the rotating column 610. A connecting groove plate 612 is fixedly connected to the circumferential surface of the rotating column 610. A fixed air pipe 608 is connected to an exhaust plate 607. The exhaust plate 607 is located above the support block 601. A liquid inlet hole is provided on the fixed cover 609, which is used to allow low-chromium environmentally friendly chromating liquid to enter the fixed cover 609. A movable frame 605 is slidably connected to the inner wall of the immersion tank 1. When the device is in use, the pressure plate 10 moves, causing the fixed cover 609 to move downwards synchronously. This movement of the fixed cover 609 causes the rotating column 610 to move synchronously, which in turn causes the spiral blade 611 to move. Simultaneously, the rotating column 610 also causes the connecting groove plate 612 to move. At this time, the fixed cover 609 can allow the low-chromium environmentally friendly chromating liquid to enter through its openings. During the spraying process of the spray plates 18 and 19, the low-chromium environmentally friendly chromating liquid moves, and the liquid... During the process, the liquid can push the connecting groove plate 612 to rotate. The rotation of the connecting groove plate 612 will drive the rotating column 610 to rotate. The rotation of the rotating column 610 will synchronously drive the spiral blade 611 to rotate. The rotation of the spiral blade 611 will drive the low-chromium environmentally friendly chromating liquid in the fixed cover 609 to move. This will allow the low-chromium environmentally friendly chromating liquid in the pressing area of ​​the pressure plate 10 to be moved, avoiding insufficient contact between the surface of the aluminum profile blank and the low-chromium environmentally friendly chromating liquid at the limiting and pushing point of the pressure plate 10. This will ensure that the surface of the aluminum profile blank can be fully coated with the low-chromium environmentally friendly chromating liquid, thereby improving the subsequent condensation quality of the device. The cleaning mechanism 7 includes a connecting block 701, which is fixedly connected to the inner wall of the movable frame 605. The inner wall of the connecting block 701 is fixedly connected to the second mounting frame 702, and the inner wall of the second mounting frame 702 is rotatably connected to the second rotating column 703. The circumferential surface of the second rotating column 703 is fixedly connected to the first sponge pressure column 704. When the device is in use, the moving frame 605 moves synchronously with the connecting block 701, which in turn moves the mounting frame 702. The mounting frame 702 moves the rotating column 703, which in turn moves the sponge pressing column 704. During this movement, the sponge pressing column 704 moves on the surface of the aluminum profile blank. As it contacts the aluminum profile blank, it generates friction, allowing it to rotate and press and spread the environmentally friendly chromizing liquid on the upper and lower sides of the aluminum profile blank evenly, ensuring that the four corners of the aluminum profile blank are fully adhered to the environmentally friendly chromizing liquid. The cleaning mechanism 7 also includes a rotating column 3 705, which is rotatably connected to the inner wall of the mounting frame 2 702. A sponge pressure column 2 706 is fixedly connected to the circumferential surface of the rotating column 3 705. There are two sponge pressure columns 1 704 on the mounting frame 2 702, and the two sponge pressure columns 1 704 are symmetrically distributed on the inner wall of the mounting frame 2 702. When the device is in use, during the movement of the mounting bracket 2 702, the movement of the mounting bracket 2 702 will drive the rotating column 3 705 to move synchronously. During the movement of the rotating column 3 705, the movement of the rotating column 3 705 will drive the sponge pressure column 2 706 to move. At this time, the sponge pressure column 2 706 can fully adhere the environmentally friendly chromic liquid to the side of the aluminum profile blank plate, ensuring the subsequent production quality and efficiency of the device. Overall working principle: The fan 606 can discharge air into the exhaust plate 607 through the fixed air pipe 608. During the movement of the exhaust plate 607, it simultaneously discharges air onto the surface of the aluminum profile blank, blowing away excess low-chromium environmentally friendly chromating liquid. This also ensures more thorough adhesion between the low-chromium environmentally friendly chromating liquid and the surface of the aluminum profile blank, allowing the low-chromium environmentally friendly chromating liquid in the pressing area of ​​the pressure plate 10 to be moved. This prevents insufficient contact between the aluminum profile blank surface and the low-chromium environmentally friendly chromating liquid at the limiting and pushing point of the pressure plate 10, thus maintaining... The device ensures that the surface of the aluminum profile blank can be fully coated with low-chromium environmentally friendly chromating solution, improving the subsequent film formation quality. Sponge pressure column 704, upon contact with the aluminum profile blank, generates friction, allowing it to rotate and press and spread the environmentally friendly chromating solution evenly on both sides of the aluminum profile blank, ensuring complete adhesion of the solution to the four corners. Sponge pressure column 706 further ensures complete adhesion of the environmentally friendly chromating solution to the sides of the aluminum profile blank, guaranteeing the subsequent production quality and efficiency of the device.
