Description

Technical Field

[0001] The present invention belongs to the technical field of galvanizing, and more specifically, particularly relates to an intelligent galvanizing device for cold-rolled sheets. Background Art

[0002] The galvanizing bath in the intelligent galvanizing device for cold-rolled sheets is a core functional component. It is generally made of high-temperature resistant and corrosion-resistant materials and can stably hold high-temperature zinc liquid. Its primary function is to provide a reaction site where the cold-rolled sheets are immersed in the zinc liquid. Through the principle of hot-dip galvanizing, a metallurgical reaction occurs between the zinc liquid and the surface of the sheets, forming a firm and uniform galvanized layer on the surface of the sheets, greatly improving the corrosion resistance and aesthetics of the cold-rolled sheets. In some advanced designs, the galvanizing bath is also equipped with a heating and temperature control system, which can accurately regulate the temperature of the zinc liquid, ensure that the galvanizing reaction proceeds under suitable conditions, and improve the galvanizing quality. At the same time, its internal structure design is conducive to the circulation and flow of the zinc liquid, reducing the unevenness of the zinc liquid composition and temperature, and ensuring that each cold-rolled sheet can obtain a consistent galvanizing effect to meet the galvanizing requirements of different specifications of cold-rolled sheets.

[0003] However, during the implementation of the above technical solutions, it is found that at least the following technical problems exist: During the galvanizing process, a layer of zinc slag will form on the surface of the zinc liquid. These zinc slags are mainly composed of impurities, oxides, and other chemical reaction products in the zinc liquid. If not removed in time, the zinc slag may adhere to the surface of the cold-rolled sheets, affecting the quality of the galvanized layer, resulting in defects such as particles and pockmarks on the surface, and reducing the appearance and corrosion resistance of the product. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides an intelligent galvanizing device for cold-rolled sheets to solve the above problems.

[0005] An intelligent galvanizing device for cold-rolled sheets includes a device main body. Two fixed long plates are fixedly connected to the upper end of the device main body. Extension long plates are fixedly connected to both ends of the device main body. Threaded rods are arranged at the upper ends of the two extension long plates. The two threaded rods are parallel to each other. Fixed blocks are rotatably connected to the front and rear ends of the two threaded rods. The lower end of each fixed block is fixedly connected to the corresponding extension long plate. Connecting columns are rotatably connected to the two fixed blocks located at the front end position. The two connecting columns correspond to the positions of the two threaded rods. The side ends of the two connecting columns pass through the fixed blocks and are fixedly connected to the corresponding two threaded rods. The two threaded rods are both threadedly sleeved with moving blocks. An L-shaped plate is arranged between the two moving blocks. Both ends of the L-shaped plate are fixedly connected to the two moving blocks.

[0006] Preferably, a synchronous chain is arranged at the front end of the device main body. Sprockets are meshingly connected to both ends of the synchronous chain. The two sprockets correspond to the positions of the two connecting columns. The two sprockets are fixedly connected to the corresponding two connecting columns.

[0007] Preferably, a U-shaped fixing plate is provided at the front end of the device main body, and the position of the U-shaped fixing plate corresponds to that of the connecting column on the left side. A motor is fixedly connected to the front end of the U-shaped fixing plate. The output port of the motor passes through the U-shaped fixing plate and is fixedly connected to the connecting column at the left side position. When the motor is started, the motor drives the connecting column on the left side to rotate.

[0008] Preferably, one end of the L-shaped plate is hinged with a movable long plate. A scraping plate is fixedly connected to the lower end of the movable long plate, and two magnetic stickers are fixedly connected to the front surface of the movable long plate.

[0009] Preferably, the front ends of the two magnetic stickers are magnetically connected to magnets, and the front ends of the two magnets are fixedly connected to the L-shaped plate.

[0010] Preferably, rectangular grooves are formed at both ends of the movable long plate, and the movable long plate is movably sleeved with two telescopic blocks through the two rectangular grooves.

[0011] Preferably, arc-shaped blocks are fixedly connected to the opposite ends of the two telescopic blocks. The arc surfaces of the two arc-shaped blocks face the rear end. The two arc-shaped blocks correspond to the two fixed long plates. Empty grooves are formed inside the two telescopic blocks, and the two telescopic blocks are movably sleeved with limiting disks through the empty grooves.

[0012] Preferably, connecting rods are fixedly connected to the opposite ends of the two limiting disks. The two connecting rods pass through the corresponding telescopic blocks and are fixedly connected to the inner wall of the movable long plate.

[0013] Preferably, springs are arranged inside the two rectangular grooves. The two connecting rods are both located inside the two springs. The opposite ends of the two springs are fixedly connected to the inner wall of the movable long plate, and the opposite ends of the two springs are fixedly connected to the corresponding telescopic blocks.

[0014] Preferably, a collection box is fixedly connected to the rear end of the device main body. A filter screen is arranged inside the collection box, and the surface of the filter screen is fixedly connected to the inner wall of the collection box.

[0015] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, when the motor starts, the motor drives the connecting column on the left side to rotate. When one connecting column rotates, since the sprockets on the two connecting columns are both meshed with the synchronous chain, the two connecting columns will synchronously drive the threaded rod to rotate. When the two threaded rods rotate, they will drive the two moving blocks and the L-shaped plate to move from front to back along the device main body. When the L-shaped plate moves from front to back, it will drive the moving long plate and the scraper to move. When the scraper moves, it will skim over the liquid surface inside the device main body. At this time, the scraper will scrape the zinc dross on the surface of the zinc liquid into the collection box, so that the zinc dross on the surface of the zinc liquid can be taken out in time, avoiding the problem that the zinc dross adheres to the surface of the cold-rolled sheet and affects the quality of the galvanized layer, and ensuring that the appearance and corrosion resistance of the cold-rolled sheet product are not affected.

[0016] In the present invention, when the moving long plate moves, the two arc-shaped blocks will also move along with the moving long plate. The positions of the two arc-shaped blocks correspond to those of the two fixed long plates. When the two arc-shaped blocks contact the fixed long plates, the two arc-shaped blocks will be squeezed into the inside of the moving long plate, enabling the moving long plate to continue moving backward until the moving long plate moves to the rear end of the device main body. At this time, the fixed long plate no longer squeezes the arc-shaped blocks, and the two arc-shaped blocks pop out. Then, the motor is controlled to output in the reverse direction, and the moving long plate drives the two arc-shaped blocks to move forward. The two arc-shaped blocks will be resisted by the two fixed long plates. At this time, the magnetic stickers on the moving long plate will cancel the magnetic connection with the magnets, making the moving long plate parallel to the device main body, avoiding the problem that when the moving long plate moves forward, it will control the scraper to scrape some zinc dross to the front end of the device main body. After the moving long plate moves to the front end of the device main body, the fixed long plate no longer resists the two arc-shaped blocks. At this time, the moving long plate rotates downward due to gravity, so that the magnetic stickers on the moving long plate are magnetically attracted to the magnets again.

[0017] In the present invention, when the two arc-shaped blocks resist the corresponding fixed long plates, the arc-shaped blocks will drive the corresponding telescopic blocks to move into the rectangular grooves. At this time, the two springs will be compressed. When the two arc-shaped blocks are no longer limited, the two springs will reset and pop out the telescopic blocks and the arc-shaped blocks. When the telescopic blocks and the arc-shaped blocks are popped out a certain distance, the limiting disc will resist the inner wall of the telescopic block, making the telescopic block unable to continue popping out with the arc-shaped block, avoiding the problem that the arc-shaped block and the telescopic block pop out excessively and cause the telescopic block to separate from the moving long plate, and making the arc-shaped block more stable when popping out.

[0018] In the present invention, after the zinc dross is scraped into the collection box, part of the zinc dross will be separated from the zinc liquid through the filter screen, solving the problem that part of the zinc liquid will be carried away when the zinc dross is scraped away, enabling the zinc liquid to be reused and improving the utilization rate of the zinc liquid.

[0019] In the present invention, when the moving long plate and the synchronous chain are perpendicular to the device main body, the two magnetic stickers will adsorb the moving long plate through the magnets, so that the moving long plate and the scraper will not swing during the movement, ensuring that the scraper can scrape out the zinc dross evenly.

Detailed Description of the Invention

[0022] The following further describes in detail the embodiments of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0023] Please refer to Figures 1 - 8, the present invention provides an intelligent galvanizing device for cold-rolled sheets, including a device main body 11. Two fixed long plates 13 are fixedly connected to the upper end of the device main body 11. Extension long plates 16 are fixedly connected to both ends of the device main body 11. Threaded rods 14 are arranged at the upper ends of the two extension long plates 16. The two threaded rods 14 are parallel to each other. Fixed blocks 15 are rotatably connected to the front and rear ends of the two threaded rods 14. The lower end of each fixed block 15 is fixedly connected to the corresponding extension long plate 16. Connecting columns 22 are rotatably connected to the two fixed blocks 15 located at the front end position. The two connecting columns 22 correspond to the positions of the two threaded rods 14. The side ends of the two connecting columns 22 pass through the fixed blocks 15 and are fixedly connected to the corresponding two threaded rods 14. Two moving blocks 17 are threadedly sleeved on the two threaded rods 14. An L-shaped plate 18 is arranged between the two moving blocks 17. Both ends of the L-shaped plate 18 are fixedly connected to the two moving blocks 17. When the two threaded rods 14 rotate, they will drive the two moving blocks 17 and the L-shaped plate 18 to move along the device main body 11 from front to back.

[0024] A synchronous chain 24 is arranged at the front end of the device main body 11. Sprockets 34 are meshingly connected to both ends of the synchronous chain 24. The two sprockets 34 correspond to the positions of the two connecting columns 22. The two sprockets 34 are fixedly connected to the corresponding two connecting columns 22. When one connecting column 22 rotates, since the sprockets 34 on the two connecting columns 22 are both meshingly connected to the synchronous chain 24, the two connecting columns 22 will synchronously drive the threaded rods 14 to rotate.

[0025] A U-shaped fixing plate 21 is arranged at the front end of the device main body 11. The U-shaped fixing plate 21 corresponds to the position of the left connecting column 22. A motor 20 is fixedly connected to the front end of the U-shaped fixing plate 21. The output port of the motor 20 passes through the U-shaped fixing plate 21 and is fixedly connected to the left connecting column 22. When the motor 20 is started, the motor 20 will drive the left connecting column 22 to rotate.

[0026] One end of the L-shaped plate 18 is hinged with a moving long plate 19. A scraping plate 23 is fixedly connected to the lower end of the moving long plate 19. When the L-shaped plate 18 moves from front to back, it will drive the moving long plate 19 and the scraping plate 23 to move. Two magnetic stickers 25 are fixedly connected to the front surface of the moving long plate 19. The front ends of the two magnetic stickers 25 are magnetically connected to magnets 26. The front ends of the two magnets 26 are fixedly connected to the L-shaped plate 18. When the moving long plate 19 and the synchronous chain 24 are perpendicular to the device main body 11, the two magnetic stickers 25 will adsorb the moving long plate 19 through the magnets 26, so that the moving long plate 19 and the scraping plate 23 will not swing during the moving process.

[0027] Rectangular grooves 28 are provided at both ends of the movable long plate 19. The movable long plate 19 is movably sleeved with two telescopic blocks 30 through the two rectangular grooves 28. Fixedly connected to the outer ends of the two telescopic blocks 30 facing away from each other are two arc-shaped blocks 27. The arc surfaces of the two arc-shaped blocks 27 face the rear end. The positions of the two arc-shaped blocks 27 correspond to those of the two fixed long plates 13. Empty grooves 32 are provided inside the two telescopic blocks 30. The two telescopic blocks 30 are movably sleeved with limiting discs 31 through the empty grooves 32. Fixedly connected to the opposite ends of the two limiting discs 31 are two connecting rods 35. The two connecting rods 35 both pass through the corresponding telescopic blocks 30 and are fixedly connected to the inner wall of the movable long plate 19. When the movable long plate 19 moves, the two arc-shaped blocks 27 will also move along with the movement of the movable long plate 19. The positions of the two arc-shaped blocks 27 correspond to those of the two fixed long plates 13. When the two arc-shaped blocks 27 come into contact with the fixed long plates 13, the two arc-shaped blocks 27 will be squeezed into the interior of the movable long plate 19, enabling the movable long plate 19 to continue moving backward until the movable long plate 19 moves to the rear end of the device main body 11. The fixed long plates 13 no longer squeeze the arc-shaped blocks 27, and the two arc-shaped blocks 27 pop out. At this time, the control motor 20 outputs in the reverse direction, and the movable long plate 19 drives the two arc-shaped blocks 27 to move forward. The two arc-shaped blocks 27 will be resisted by the two fixed long plates 13. At this time, the magnetic sticker 25 on the movable long plate 19 will cancel the magnetic connection with the magnet 26, making the movable long plate 19 parallel to the device main body 11, avoiding the problem that when the movable long plate 19 moves forward, it will control the scraping plate 23 to scrape some zinc slag to the front end of the device main body 11. When the movable long plate 19 moves to the front end of the device main body 11, the fixed long plates 13 no longer resist the two arc-shaped blocks 27. At this time, the movable long plate 19 rotates downward under gravity, so that the magnetic sticker 25 on the movable long plate 19 is magnetically attracted to the magnet 26 again.

[0028] Inside both of the two rectangular grooves 28, there are springs 29 provided. Both of the two connecting rods 35 are located inside the two springs 29. One end of the two springs 29 facing each other is fixedly connected to the inner wall of the moving long plate 19, and one end of the two springs 29 facing away from each other is fixedly connected to the corresponding telescopic block 30. At the rear end of the device main body 11, there is a collection box 12 fixedly connected. Inside the collection box 12, there is a filter screen 33. When the zinc slag is scraped into the collection box 12, part of the zinc slag and the zinc liquid will be separated through the filter screen 33, solving the problem that part of the zinc liquid will be carried when the zinc slag is scraped away, enabling the zinc liquid to be reused and improving the utilization rate of the zinc liquid. The surface of the filter screen 33 is fixedly connected to the inner wall of the collection box 12. When the two arc-shaped blocks 27 abut against the corresponding fixed long plates 13, the arc-shaped blocks 27 will drive the corresponding telescopic blocks 30 to move into the rectangular grooves 28. At this time, the two springs 29 will be compressed. When the two arc-shaped blocks 27 are no longer limited, the two springs 29 will reset and eject the telescopic blocks 30 and the arc-shaped blocks 27. When the telescopic blocks 30 and the arc-shaped blocks 27 are ejected a certain distance, the limit disc 31 will abut against the inner wall of the telescopic block 30, making the telescopic block 30 unable to continue ejecting with the arc-shaped block 27, avoiding the problem that the arc-shaped block 27 and the telescopic block 30 are ejected excessively and causing the telescopic block 30 to be separated from the arc-shaped block 27 on the moving long plate 19, making the arc-shaped block 27 more stable when ejecting.

[0029] Working principle: In the first step, when the motor 20 starts, the motor 20 will drive the connecting column 22 on the left side to rotate. When one connecting column 22 rotates, since the sprockets 34 on the two connecting columns 22 are both meshed with the synchronous chain 24, the two connecting columns 22 will synchronously drive the threaded rods 14 to rotate. When the two threaded rods 14 rotate, they will drive the two moving blocks 17 and the L-shaped plate 18 to move along the device main body 11 from front to back. When the L-shaped plate 18 moves from front to back, it will drive the moving long plate 19 and the scraper 23 to move. When the scraper 23 moves, it will skim over the liquid surface inside the device main body 11. At this time, the scraper 23 will scrape the zinc slag on the surface of the zinc liquid into the collection box 12, enabling the zinc slag on the surface of the zinc liquid to be taken out in time, avoiding the problem that the zinc slag adheres to the surface of the cold-rolled sheet and affects the quality of the galvanized layer, and making the appearance and corrosion resistance of the cold-rolled sheet product unaffected.

[0030] Second step, when the moving long plate 19 moves, the two arc-shaped blocks 27 will also move along with the movement of the moving long plate 19. The positions of the two arc-shaped blocks 27 correspond to those of the two fixed long plates 13. When the two arc-shaped blocks 27 come into contact with the fixed long plates 13, the two arc-shaped blocks 27 will be squeezed into the interior of the moving long plate 19, enabling the moving long plate 19 to continue moving backward until the moving long plate 19 moves to the rear end of the device main body 11. At this time, the fixed long plate 13 no longer squeezes the arc-shaped blocks 27, and the two arc-shaped blocks 27 pop out. Then, the control motor 20 outputs in the reverse direction, and the moving long plate 19 drives the two arc-shaped blocks 27 to move forward. The two arc-shaped blocks 27 will be blocked by the two fixed long plates 13. At this time, the magnetic stickers 25 on the moving long plate 19 will cancel the magnetic connection with the magnets 26, making the moving long plate 19 parallel to the device main body 11, thus avoiding the problem that when the moving long plate 19 moves forward, it will control the scraping plate 23 to scrape some zinc slag to the front end of the device main body 11. When the moving long plate 19 moves to the front end of the device main body 11, the fixed long plate 13 no longer blocks the two arc-shaped blocks 27. At this time, the moving long plate 19 rotates downward due to gravity, causing the magnetic stickers 25 on the moving long plate 19 to be magnetically attracted to the magnets 26 again.

[0031] Third step, when the two arc-shaped blocks 27 block the corresponding fixed long plates 13, the arc-shaped blocks 27 will drive the corresponding telescopic blocks 30 to move into the rectangular grooves 28. At this time, the two springs 29 will be compressed. When the two arc-shaped blocks 27 are no longer limited, the two springs 29 will reset and pop out the telescopic blocks 30 and the arc-shaped blocks 27. When the telescopic blocks 30 and the arc-shaped blocks 27 are popped out a certain distance, the limit disks 31 will block the inner walls of the telescopic blocks 30, making the telescopic blocks 30 unable to continue popping out with the arc-shaped blocks 27, thus avoiding the problem that the arc-shaped blocks 27 and the telescopic blocks 30 pop out excessively and cause the telescopic blocks 30 to separate from the moving long plate 19, making the arc-shaped blocks 27 more stable when popping out.

[0032] Fourth step, after the zinc slag is scraped into the collection box 12, part of the zinc slag will be separated from the zinc liquid through the filter screen 33, solving the problem that when the zinc slag is scraped away, it will carry some zinc liquid, enabling the zinc liquid to be reused and improving the utilization rate of the zinc liquid.

[0033] Fifth step, when the moving long plate 19 and the synchronous chain 24 are perpendicular to the device main body 11, the two magnetic stickers 25 will adsorb the moving long plate 19 through the magnets 26, making the moving long plate 19 and the scraping plate 23 not swing during the movement, ensuring that the scraping plate 23 can scrape out the zinc slag evenly.

[0034] The embodiments of the present invention are provided by way of example and description, and are not exhaustive or limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better illustrate the principles of the present invention and its practical applications, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.
