Description

Technical Field

[0001] This invention relates to the field of metal coating technology, and more specifically to a device for rapid coating treatment of stainless steel strip surfaces. Background Technology

[0002] Stainless steel coating is a method to improve the properties of stainless steel by forming a thin film on the surface of stainless steel. This film can protect the stainless steel surface, enhance corrosion resistance, increase hardness and reduce the coefficient of friction. Stainless steel coating is mainly divided into two types: physical coating and chemical coating.

[0003] Physical coating is a method of forming a thin metal film on the surface of stainless steel using vacuum technology. Common physical coating methods include evaporation coating, which involves heating the metal material to its melting point and then evaporating it into a gas phase. Finally, the ions of the coating material come into contact with the material to be coated to form a thin film.

[0004] When coating steel strips, the steel strips have a certain deformation capacity. If they are left to stand and bend at will, the contact area between different parts of the steel strip and the coating material vapor will be different, resulting in different coating thicknesses and affecting the coating effect. After one coating is completed, the steel strip needs to be removed. At this time, the coating vapor that is not completely consumed is easily dispersed into the air, which not only wastes raw materials but also causes great pollution to the external environment. Therefore, we have proposed a rapid coating treatment device for stainless steel strip surfaces. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides a rapid coating treatment device for stainless steel strip surface, including a base plate, a base fixedly connected to the top of the base plate, and two bases symmetrically arranged. A coating mechanism is arranged on the side of the base plate away from the base. The coating mechanism further includes a first shell and a second shell, which are symmetrically arranged on the top of the base plate. The inner walls of the first shell and the second shell are rotatably connected to a sealed cabinet door via a rotating rod. The two bases are fixedly connected to the first shell and the second shell respectively on the side away from the base plate. A pipe is arranged at the interval between the first shell and the second shell. The two ends of the pipe are fixedly connected to the outer surfaces of the first shell and the second shell respectively, and the inner cavity of the pipe is connected to the inner cavity of the first shell and the second shell. A vacuum pump is arranged at the interval between the first shell and the second shell and is fixedly installed on the pipe. A valve is arranged at the interval between the vacuum pump and the first shell and is fixedly installed on the pipe. A tensioning mechanism is arranged inside the first shell and the second shell. An evaporation mechanism is installed on the side of the second outer shell near the base. First, the steel strip is processed inside the first outer shell. The sealed cabinet door is opened, and a batch of steel strips to be processed is fixed by a tensioning mechanism. Then, the coating material is placed inside the evaporation mechanism, the sealed cabinet door is closed, and the valve is opened. Next, the vacuum pump is turned on, drawing air from inside the first outer shell into the second outer shell. The evaporation mechanism evaporates the coating material, forming a uniform and dense film on the surface of the steel strip. After processing is completed inside the first outer shell, the valve is opened, and the coating material vapor flows into the pipe and into the second outer shell. The vacuum pump is started again, pumping the vapor from inside the first outer shell into the second outer shell for further processing. Simultaneously, the steel strip inside the first outer shell is cooled. Finally, the steel strip is removed from the first outer shell. The coating process is performed sequentially inside the first and second outer shells, effectively utilizing the cooling time of the steel strip. The vacuum pump transfers the processed coating material vapor, preventing waste and preventing vapor from escaping when the steel strip is removed. This fully utilizes the cooling time of the steel strip while preventing the coating material vapor from dissipating into the air and causing waste or air pollution.

[0006] Furthermore, the tensioning mechanism includes a motor, which is fixedly connected to the top of the inner wall of the first housing. A rotating shaft is fixedly connected to the side of the motor near the base, and the rotating shaft is fixedly connected to the output end of the motor. Frames are symmetrically arranged inside the first housing, and the outer surface of the rotating shaft is rotatably connected to the inner wall of the frame. Ring plates are fixedly connected to the outer surfaces of both frames, and the outer surfaces of the ring plates are rotatably connected to the inner wall of the first housing. Rectangular slots are provided on the sides of the two frames that are close to each other, and clamping components are provided inside the rectangular slots. The output end of the motor drives the rotating shaft to rotate, thereby rotating the steel strip inside the first housing. This ensures that the steel strip comes into uniform contact with the coating vapor inside the first housing, preventing defects from occurring on the surface of the steel strip during coating.

[0007] Furthermore, a sliding rod is fixedly connected to the inner wall of the ring plate near the motor, and the sliding rod is slidably connected to the ring plate away from the motor. Several sliding rods are arranged along the circumference of the ring plate. A spring is arranged at the interval between two ring plates. The two ends of the spring are fixedly connected to the side of the two ring plates that are close to each other. The spring is sleeved on the outside of the sliding rod and is set to the extended state. Moving the ring plate near the base will cause the spring to compress. After the steel strip is fixed, the spring will extend, thereby tightening the steel strip so that the steel strip is vertical above the evaporation mechanism. This allows the steel strip to fully contact the coating material vapor, while avoiding the steel strip curling up and causing different contact areas. This ensures that the coating thickness is the same at all positions of the steel strip, thereby guaranteeing the surface quality of the steel strip after coating.

[0008] Furthermore, the clamping assembly includes arc-shaped plates, two of which are symmetrically arranged inside the rectangular groove. The ends of the two arc-shaped plates that are far apart from each other are fixedly connected to the inner wall of the rectangular groove. The outer surface of the arc-shaped plates is provided with notches, which are located on the side of the two arc-shaped plates that are close to each other. The number of notches is evenly distributed. When a steel strip is inserted into the rectangular groove, the steel strip squeezes the arc-shaped plates, causing the arc-shaped plates to move away from each other. Under the elastic force of the arc-shaped plates as they recover their deformation, the steel strip is clamped. At the same time, by providing notches, the arc-shaped plates are divided into several clamping parts, so that the arc-shaped plates can clamp two steel strips of different thicknesses. Thus, in small-batch coating, a set of arc-shaped plates can clamp two steel strips of different thicknesses, avoiding the separation of steel strips of different thicknesses for coating due to fixation, thereby improving the efficiency of small-batch processing.

[0009] Furthermore, spring plates are fixedly connected to the opposite sides of the two curved plates, and several sets of spring plates are provided. Each set of spring plates is symmetrically arranged at the intervals of several slots. The end of the spring plate away from the curved plate is fixedly connected to the inner wall of the rectangular groove. By providing spring plates, additional elastic force can be provided when the curved plate clamps the steel strip, thereby improving the clamping effect of the curved plate and ensuring that the steel strip will not fall off due to air resistance when rotating. At the same time, the symmetrical arrangement of several sets of spring plates at the intervals of several slots can ensure that the same curved plate can clamp steel strips of different thicknesses.

[0010] Furthermore, the cleaning assembly includes cleaning cylinders, which are symmetrically arranged on both sides of the frame away from the motor. An inclined scraper is fixedly connected to the side of the two cleaning cylinders that is away from each other. The inner wall of the inclined scraper is slidably connected to the outer surface of the rotating shaft. Several inclined scrapers are arranged circumferentially around the cleaning cylinders. A rod is fixedly connected to the side of the two cleaning cylinders that is close to each other. A groove is provided at the end of the rod away from the cleaning cylinder. The grooves are located on both sides of the frame, and the outer surface of the rod is fixedly connected to the inner wall of the groove. When adjusting the clamping assembly to fix the steel strip, the frame away from the motor moves, which in turn moves the rod. The movement of the rod moves the cleaning cylinder, which in turn moves the inclined scraper, thereby scraping the surface of the shaft to clean it. This prevents the coating vapor from evaporating and adhering to the shaft surface, which would increase the shaft thickness, cause the frame to move slowly, or even jam, preventing the steel strip from being tightened. It also prevents the steel strip from deforming due to resistance when rotating, thus avoiding uneven coating thickness on both sides of the steel strip and ensuring the surface quality of the coated steel strip.

[0011] Furthermore, a sleeve is provided at the interval between the cleaning cylinder and the frame, and an arc scraper is fixedly connected to the side of the sleeve near the axis of the cleaning cylinder. The inner wall of the arc scraper is slidably connected to the outer surface of the rotating shaft. Several sleeves are arranged along the circumference of the arc scraper, and the inner walls of several sleeves are respectively fixedly connected to the outer surface of the rod. The movement of the rod drives the movement of the sleeve, and the movement of the sleeve drives the movement of the arc scraper. The arc scraper scrapes the surface of the rotating shaft, thereby further cleaning the surface of the rotating shaft and further preventing the diameter of the rotating shaft from increasing.

[0012] Furthermore, the evaporation mechanism includes a cylinder, and the outer surface of the cylinder is fixedly connected to the inner wall of the base. A partition is fixedly connected to the inner wall of the cylinder, and an electric heating wire is provided at the interval between the partition and the bottom of the inner wall of the base. The electric heating wire is fixedly installed inside the cylinder. When the electric heating wire is activated, the electric heating wire generates heat to heat the plating material on the top of the partition. The partition separates the plating material and the electric heating wire, preventing plating material vapor from adhering to the electric heating wire and affecting the heat release effect, and at the same time preventing plating material vapor from corroding the electric heating wire and affecting its service life.

[0013] Furthermore, a stirring shaft is rotatably connected to the side of the partition away from the heating wire, and the end of the stirring shaft away from the partition is fixedly connected to the end of the rotating shaft away from the motor. A scraper frame is fixedly connected to the outer surface of the stirring shaft, and the side of the scraper frame away from the stirring shaft is slidably connected to the inner wall of the cylinder. Several scraper frames are arranged along the circumference of the stirring shaft. When the rotating shaft rotates, it drives the stirring shaft to rotate, thereby driving the scraper frames to rotate. The scraper frames stir the molten coating material, so that it is fully heated, thereby increasing the steam generation rate. The coating material evaporates, and the volume of the coating material inside the cylinder decreases. The scraper frames scrape off the coating material adhering to the inner wall of the cylinder, thereby ensuring that all the coating material can be fully evaporated and used.

[0014] Furthermore, a scraper is fixedly connected to the outer surface of the scraping frame. The scraper is arranged along the rotation direction of the stirring shaft. The side of the scraper away from the scraping frame is sloped. The rotation of the scraping frame drives the scraper to rotate, and the scraper further scrapes the inner wall of the cylinder, improving the scraping effect. At the same time, the slope of the scraper can promote the plating solution to slide down the scraper while scraping it off, which has a guiding effect on the plating solution and further improves the scraping effect.

[0015] Furthermore, stirring blades are provided at the intervals of the scraping frame, and the stirring blades are curved. The two ends of the stirring blades are respectively fixedly connected to the opposite sides of the inner wall of the adjacent scraping frame. The number of stirring blades corresponds to the number of scraping frames. The rotation of the scraping frame drives the stirring blades to rotate, and the rotation of the stirring blades stirs the coating material inside the cylinder. The curved design of the stirring blades can promote the mixing of coating materials at different heights during stirring, thereby further improving the stirring effect and promoting the evaporation of the coating material. At the same time, the rotation of the curved stirring blades can generate an upward airflow, which can drive the coating material vapor to rise and approach the steel strip, thereby promoting the contact between the steel strip and the coating material vapor and improving the coating effect.

[0016] Furthermore, a top plate is fixedly connected to the side of the cylinder away from the base, and the inner wall of the top plate is rotatably connected to the outer surface of the stirring shaft. A fan-shaped plate is slidably connected to the side of the top plate away from the cylinder, and the fan-shaped plate is fixedly connected to the outer surface of the stirring shaft. Several fan-shaped plates are arranged along the circumference of the stirring shaft, and evaporation holes are arranged at intervals between the fan-shaped plates. Several evaporation holes are evenly opened on the outer surface of the top plate. When the stirring shaft rotates, it drives the fan-shaped plates to rotate. When the fan-shaped plates block the evaporation holes, the coating material vapor inside the cylinder expands and the pressure rises. As a result, when the evaporation holes leak out, the spray height of the coating material vapor increases, thereby improving the coating effect. At the same time, the coating material vapor that is intermittently sprayed with the rotating shaft can only be sprayed when the steel strip is at the top of the evaporation hole, improving the utilization efficiency of the coating material vapor and avoiding the continuous spraying of coating material vapor, which would adhere to the surface of non-steel strip parts and cause waste.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. By setting up a first outer shell and a second outer shell, and performing coating processing inside the first outer shell and the second outer shell in sequence, the present invention can effectively utilize the cooling time of the steel strip. At the same time, the vacuum pump transfers the vapor of the coated material after processing, avoiding waste of the coated material and preventing the coated material vapor from surging out when the steel strip is removed. While making full use of the cooling time of the steel strip, it avoids the waste of the coated material vapor from dissipating into the air and avoiding air pollution.

[0019] 2. This invention features a tensioning mechanism with a spring in an extended state. Moving the ring plate near the base compresses the spring, fixing the steel strip. The spring then extends, tightening the steel strip so that it is vertical above the evaporation mechanism. This ensures the steel strip is in full contact with the coating material vapor, while preventing the steel strip from curling up and causing uneven contact areas. This ensures the same coating thickness at all points on the steel strip, thus guaranteeing the surface quality of the coated steel strip.

[0020] 3. This invention uses an arc-shaped plate to clamp the steel strip under the elastic force of the arc-shaped plate's deformation recovery. Simultaneously, by incorporating notches, the arc-shaped plate is divided into several clamping sections, allowing it to clamp two steel strips of different thicknesses. This enables small-batch coating by using a single set of arc-shaped plates to clamp two steel strips of different thicknesses, preventing them from being coated separately due to fixation, thus improving small-batch processing efficiency. The elastic plates provide additional elasticity when the arc-shaped plate clamps the steel strip, enhancing the clamping effect and ensuring the steel strip does not fall off due to air resistance during rotation. Furthermore, several sets of elastic plates are symmetrically arranged at the intervals of the notches, ensuring that the same arc-shaped plate can clamp steel strips of different thicknesses.

[0021] 4. This invention incorporates a scraping frame that stirs the molten plating material, ensuring it is fully heated and increasing the steam generation rate. This causes the plating material to evaporate, reducing its volume inside the cylinder. The scraping frame then scrapes off any plating material adhering to the inner wall of the cylinder, ensuring all plating material is fully evaporated and usable. The rotation of the scraping frame drives the scraper to rotate, further scraping the inner wall of the cylinder and improving the scraping effect. Simultaneously, the scraper has a slope, which guides the plating solution as it slides down the scraper, further enhancing the scraping effect.

[0022] 5. This invention incorporates stirring blades that rotate to agitate the coating material inside the cylinder. The curved design of the stirring blades promotes mixing of coating materials at different heights during agitation, thereby further improving the agitation effect and promoting the evaporation of the coating material. Simultaneously, the rotating curved stirring blades generate upward airflow, which carries the coating material vapor upward, bringing it closer to the steel strip and promoting contact between the steel strip and the coating material vapor, thus improving the coating effect.

[0023] 6. This invention cleans the rotating shaft surface by setting up a cleaning component and moving an inclined scraper. This prevents the coating vapor from evaporating and adhering to the rotating shaft surface, which would increase the shaft thickness, cause the frame to move slowly or even jam, and prevent the steel strip from being tightened. This also prevents the steel strip from deforming due to resistance when rotating, thus avoiding different coating thicknesses on both sides of the steel strip and ensuring the surface quality of the coated steel strip.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0037] Example 1

[0038] Please see Figures 1-8This invention relates to a rapid coating treatment device for stainless steel strip surfaces, comprising a base plate 1, with two bases 2 symmetrically arranged on the top of the base plate 1. A coating mechanism 3 is disposed on the side of the base plate 1 away from the bases 2. The coating mechanism 3 further includes a first outer shell 31 and a second outer shell 38, which are symmetrically arranged on the top of the base plate 1. The inner walls of both the first outer shell 31 and the second outer shell 38 are rotatably connected to a sealing cabinet door 32 via a rotating rod. The sides of the two bases 2 away from the base plate 1 are respectively fixedly connected to the first outer shell 31 and the second outer shell 38. A pipe 33 is provided at the interval of the outer casing 38. Both ends of the pipe 33 are fixedly connected to the outer surfaces of the first outer casing 31 and the second outer casing 38, respectively, and the inner cavity of the pipe 33 is connected to the inner cavities of the first outer casing 31 and the second outer casing 38. A vacuum pump 34 is provided at the interval between the first outer casing 31 and the second outer casing 38, and the vacuum pump 34 is fixedly mounted on the pipe 33. A valve 35 is provided at the interval between the vacuum pump 34 and the first outer casing 31, and the valve 35 is fixedly mounted on the pipe 33. A tensioning mechanism 36 is provided inside both the first outer casing 31 and the second outer casing 38. An evaporation mechanism 37 is provided on one side of the base 2. First, a steel strip is processed inside the first outer shell 31. The sealed cabinet door 32 is opened, and a batch of steel strips to be processed is fixed by the tensioning mechanism 36. Then, the plating material is placed inside the evaporation mechanism 37, the sealed cabinet door 32 is closed, the valve 35 is opened, and then the vacuum pump 34 is turned on to draw air from inside the first outer shell 31 into the second outer shell 38. The evaporation mechanism 37 evaporates the plating material, forming a uniform and dense film on the surface of the steel strip. After processing is completed inside the first outer shell 31, the valve 35 is opened, and the plating material vapor flows into the pipe 33 and enters the second outer shell 38. The vacuum pump 34 is started to pump the steam inside the first housing 31 into the second housing 38 for further processing inside the second housing 38. At the same time, the steel strip inside the first housing 31 is cooled. Finally, the steel strip inside the first housing 31 is removed. The coating process is carried out sequentially through the first housing 31 and the second housing 38, which can effectively utilize the cooling time of the steel strip. At the same time, the vacuum pump 34 transfers the processed coating material vapor to avoid waste of coating material and prevents coating material vapor from surging out when the steel strip is removed. While making full use of the cooling time of the steel strip, the coating material vapor is prevented from dissipating into the air and causing waste and air pollution.

[0039] The tensioning mechanism 36 includes a motor 361, which is fixedly connected to the top of the inner wall of the first housing 31. A rotating shaft 362 is fixedly connected to the side of the motor 361 near the base 2, and the rotating shaft 362 is fixedly connected to the output end of the motor 361. Frames 363 are symmetrically arranged inside the first housing 31, and the outer surface of the rotating shaft 362 is rotatably connected to the inner wall of the frame 363. A ring plate 364 is fixedly connected to the outer surface of both frames 363, and the outer surface of the ring plate 364 is rotatably connected to the inner wall of the first housing 31. A rectangular groove 365 is opened on the side of the two frames 363 that are close to each other, and a clamping component 368 is provided inside the rectangular groove 365. The output end of the motor 361 drives the rotating shaft 362 to rotate, thereby causing the steel strip inside the first housing 31 to rotate, so that the steel strip comes into uniform contact with the coating vapor inside the first housing 31, ensuring that no defects occur on the surface of the steel strip during coating.

[0040] A slide rod 366 is fixedly connected to the inner wall of the ring plate 364 near the motor 361, and the slide rod 366 is slidably connected to the ring plate 364 away from the motor 361. Several slide rods 366 are arranged along the circumference of the ring plate 364. A spring 367 is arranged at the interval between two ring plates 364. The two ends of the spring 367 are fixedly connected to the side of the two ring plates 364 that are close to each other, and the spring 367 is sleeved on the outside of the slide rod 366. The spring 367 is set to the extended state. Moving the ring plate 364 near the base 2 will cause the spring 367 to be compressed. After fixing the steel strip, the spring 367 will extend, thereby tightening the steel strip so that the steel strip is vertical above the evaporation mechanism 37. This will allow the steel strip to fully contact the coating material vapor, while avoiding the steel strip curling up and causing different contact areas, thus ensuring that the coating thickness is the same at all positions of the steel strip, thereby ensuring the surface quality of the steel strip after coating.

[0041] The clamping assembly 368 includes two arc-shaped plates 3681. Two arc-shaped plates 3681 are symmetrically arranged inside the rectangular groove 365, with one end of each arc-shaped plate 3681 being fixedly connected to the inner wall of the rectangular groove 365. The outer surface of each arc-shaped plate 3681 has a notch 3682, located on the side of the two arc-shaped plates 3681 that are close to each other. Several notches 3682 are evenly distributed. When a steel strip is inserted into the rectangular groove 365, the steel strip compresses the arc-shaped plates 3681. The curved plates 3681 are far apart from each other. Under the elastic force of the curved plate 3681 restoring its deformation, the steel strip is clamped. At the same time, by setting a notch 3682, the curved plate 3681 is divided into several clamping parts. Thus, the curved plate 3681 can clamp two steel strips of different thicknesses. Therefore, in small batch coating, a set of curved plates 3681 can clamp two steel strips of different thicknesses, avoiding the steel strips of different thicknesses from being coated separately due to fixation, thereby improving the efficiency of small batch processing.

[0042] Two curved plates 3681 are fixedly connected to each other on their opposite sides. Several sets of spring plates 3683 are provided, and each set of spring plates 3683 is symmetrically arranged at the intervals of several notches 3682. The end of the spring plate 3683 away from the curved plate 3681 is fixedly connected to the inner wall of the rectangular groove 365. By setting the spring plates 3683, additional elastic force can be provided when the curved plate 3681 clamps the steel strip, thereby improving the clamping effect of the curved plate 3681 and ensuring that the steel strip will not fall off due to air resistance when rotating. At the same time, the symmetrical arrangement of several sets of spring plates 3683 at the intervals of several notches 3682 can ensure that the same curved plate 3681 can clamp steel strips of different thicknesses.

[0043] The cleaning assembly 39 includes cleaning cylinders 391, which are symmetrically arranged on both sides of the frame 363 away from the motor 361. An inclined scraper 392 is fixedly connected to the side of the two cleaning cylinders 391 that is far apart from each other. The inner wall of the inclined scraper 392 is slidably connected to the outer surface of the rotating shaft 362, and several inclined scrapers 392 are arranged circumferentially around the cleaning cylinders 391. A rod 393 is fixedly connected to the side of the two cleaning cylinders 391 that is close to each other. A groove 394 is provided at the end of the rod 393 away from the cleaning cylinder 391. The grooves 394 are located on both sides of the frame 363, and the outer surface of the rod 393 is fixedly connected to the inner wall of the groove 394. When adjusting the clamping assembly 368 to fix the steel strip, the frame 363, which is away from the motor 361, moves, driving the rod 393 to move. The movement of the rod 393 drives the cleaning cylinder 391 to move, and the movement of the cleaning cylinder 391 drives the inclined scraper 392 to move, thereby scraping the surface of the rotating shaft 362 to clean it. This prevents the coating vapor from evaporating and adhering to the surface of the rotating shaft 362, which would increase the thickness of the rotating shaft 362, causing the frame 363 to move slowly or even jam, preventing the steel strip from being tightened. This also prevents the steel strip from deforming due to resistance when rotating, thus avoiding different coating thicknesses on both sides of the steel strip and ensuring the surface quality of the coated steel strip.

[0044] A sleeve 395 is provided at the interval between the cleaning cylinder 391 and the frame 363. An arc scraper 396 is fixedly connected to the side of the sleeve 395 near the axis of the cleaning cylinder 391. The inner wall of the arc scraper 396 is slidably connected to the outer surface of the rotating shaft 362. Several sleeves 395 are arranged around the circumference of the arc scraper 396. The inner walls of several sleeves 395 are fixedly connected to the outer surface of the rod 393. The movement of the rod 393 drives the movement of the sleeves 395, which in turn drives the movement of the arc scraper 396. The arc scraper 396 scrapes the surface of the rotating shaft 362, thereby further cleaning the surface of the rotating shaft 362 and further preventing the diameter of the rotating shaft 362 from increasing.

[0045] Example 2

[0046] Please see Figures 9-11The evaporation mechanism 37 includes a cylinder 371, and the outer surface of the upper cylinder 371 is fixedly connected to the inner wall of the base 2. A partition 372 is fixedly connected to the inner wall of the cylinder 371, and an electric heating wire 373 is provided at the gap between the partition 372 and the bottom of the inner wall of the base 2. The electric heating wire 373 is fixedly installed inside the cylinder 371. When the electric heating wire 373 is activated, the electric heating wire 373 generates heat to heat the plating material on the top of the partition 372. The partition 372 separates the plating material and the electric heating wire 373 to prevent the plating material vapor from adhering to the electric heating wire 373 and affecting the heat release effect. At the same time, it also prevents the plating material vapor from corroding the electric heating wire 373 and affecting its service life.

[0047] A stirring shaft 374 is rotatably connected to the side of the partition 372 away from the heating wire 373. The end of the stirring shaft 374 away from the partition 372 is fixedly connected to the end of the rotating shaft 362 away from the motor 361. A scraper frame 375 is fixedly connected to the outer surface of the stirring shaft 374. The side of the scraper frame 375 away from the stirring shaft 374 is slidably connected to the inner wall of the cylinder 371. Several scraper frames 375 are arranged around the circumference of the stirring shaft 374. When the rotating shaft 362 rotates, it drives the stirring shaft 374 to rotate, thereby driving the scraper frame 375 to rotate. The scraper frame 375 stirs the molten coating material, making it fully heated, thereby increasing the steam generation rate. The coating material evaporates, and the volume of the coating material inside the cylinder 371 decreases. The scraper frame 375 scrapes off the coating material adhering to the inner wall of the cylinder 371, thereby ensuring that all coating materials can be fully evaporated and used.

[0048] A scraper 376 is fixedly connected to the outer surface of the scraping frame 375. The scraper 376 is arranged along the rotation direction of the stirring shaft 374. The side of the scraper 376 away from the scraping frame 375 is provided with a slope. The rotation of the scraping frame 375 drives the scraper 376 to rotate. The scraper 376 further scrapes the inner wall of the cylinder 371, improving the scraping effect. At the same time, the slope of the scraper 376 can promote the plating solution to slide down along the scraper 376 while scraping it off, which has a guiding effect on the plating solution and further improves the scraping effect.

[0049] Stirring blades 377 are provided at intervals of the scraping frame 375. The stirring blades 377 are bent. The two ends of the stirring blades 377 are respectively fixedly connected to the opposite sides of the inner wall of the adjacent scraping frame 375. The number of stirring blades 377 corresponds to the number of scraping frames 375. The rotation of the scraping frame 375 drives the stirring blades 377 to rotate. The rotation of the stirring blades 377 stirs the coating material inside the cylinder 371. The bent design of the stirring blades 377 can promote the mixing of coating materials at different heights during stirring, thereby further improving the stirring effect and promoting the evaporation of the coating material. At the same time, the rotation of the bent stirring blades 377 can generate an upward wind force, which can drive the coating material vapor to rise and approach the steel strip, thereby promoting the contact between the steel strip and the coating material vapor and improving the coating effect.

[0050] A top plate 378 is fixedly connected to the side of the cylinder 371 away from the base 2, and the inner wall of the top plate 378 is rotatably connected to the outer surface of the stirring shaft 374. A sector plate 3710 is slidably connected to the side of the top plate 378 away from the cylinder 371. The sector plate 3710 is fixedly connected to the outer surface of the stirring shaft 374, and several sector plates 3710 are arranged along the circumference of the stirring shaft 374. Evaporation holes 379 are arranged at the intervals of the sector plates 3710, and several evaporation holes 379 are evenly distributed on the outer surface of the top plate 378. Rotation of 374 drives the sector plate 3710 to rotate. When the sector plate 3710 blocks the evaporation hole 379, the coating material vapor inside the cylinder 371 expands and the pressure rises. As a result, when the coating material vapor leaks out of the evaporation hole 379, the spray height of the coating material vapor increases, thereby improving the coating effect. At the same time, the coating material vapor that is intermittently sprayed with the rotating shaft 362 can only be sprayed when the steel strip is at the top of the evaporation hole 379 with the rotating shaft 362, improving the utilization efficiency of the coating material vapor and avoiding the coating material vapor from being continuously sprayed out and adhering to the surface of non-steel strip parts, causing waste.

[0051] In use, firstly, a steel strip is machined inside the first outer shell 31. The sealed cabinet door 32 is opened, and the steel strip is inserted into the rectangular groove 365. The steel strip presses against the arc-shaped plates 3681, causing the arc-shaped plates 3681 to move away from each other. Under the elastic force of the arc-shaped plates 3681 recovering their deformation, the steel strip is clamped. After the steel strip is fixed, the spring 367 extends, thus tightening the steel strip. Then, the plating material is placed on top of the partition 372. The sealed cabinet door 32 is closed, followed by opening the valve 35. Next, the vacuum pump 34 is turned on, drawing air from inside the first outer shell 31 into the second outer shell 38. The valve 35 is closed, and the vacuum pump 34 is turned off. The heating wire 373 is started, generating heat to heat the plating material on top of the partition 372. The motor 361 is started, and its output drives the rotating shaft 362 to rotate, thereby rotating the frame 363, which in turn rotates the fixed steel strip. The rotating shaft 362 rotates, driving the stirring shaft 374 to rotate, thereby rotating the scraper frame 375. The rotating scraper frame 375 stirs the molten plating material. The rotation of the scraper frame 375 drives the stirring blade 377 to rotate, which in turn stirs the plating material inside the cylinder 371. The curved stirring blade 377 generates upward airflow when rotating, which drives the plating material vapor to rise. The rotating stirring shaft 374 drives the fan-shaped plate 3710 to rotate. When the fan-shaped plate 3710 blocks the evaporation hole 379, the plating material vapor inside the cylinder 371 expands and the pressure rises. As a result, when the vapor leaks out of the evaporation hole 379, the plating material vapor is sprayed out and forms a uniform and dense film on the surface of the steel strip. After the processing is completed inside the first outer shell 31, the valve 35 is opened, and the plating material vapor rushes into the pipe 33 and enters the second outer shell 38. The vacuum pump 34 is started again to pump the vapor inside the first outer shell 31 into the second outer shell 38. The processing is carried out again inside the second outer shell 38, while the steel strip inside the first outer shell 31 is cooled. Finally, the steel strip inside the first outer shell 31 is removed.
