Description

Technical Field

[0001] The present invention relates to the technical field of zinc slag scraping for hot-dip galvanized sheets, and specifically to a zinc slag scraping device for hot-dip galvanized sheets and a hot-dip galvanized sheet. Background Art

[0002] A hot-dip galvanized sheet is a steel surface treatment process in which a steel sheet is immersed in molten zinc liquid for coating. It can form a strong zinc coating on the surface of the steel sheet, thereby improving the corrosion resistance, oxidation resistance and service life of the steel sheet. Hot-dip galvanized sheets are widely used in fields such as construction, automobiles, household appliances, machinery, and transportation. After galvanizing, there will be zinc slag on the surface of the hot-dip galvanized sheet. The zinc slag will affect the smoothness and flatness of the surface of the hot-dip galvanized sheet. In order to avoid the zinc slag affecting subsequent processing such as color coating, it is necessary to scrape the slag, and a slag scraping device is required for slag scraping.

[0003] Chinese Invention Patent: CN221822296U, discloses a zinc slag scraping device for a hot-dip galvanized sheet production line, including a placement seat, a support frame and an electric telescopic rod. Electric telescopic rods are arranged on both sides of the top of the placement seat. The top of the electric telescopic rod is provided with a cover plate. The bottom of the cover plate is provided with a zinc slag scraping device main body. The bottom of the zinc slag scraping device main body is provided with a scraping blade. A clamping structure is arranged on the top of the placement seat, and a collection structure is arranged at the back end of the placement seat. The clamping structure includes a bidirectional threaded rod, a threaded sleeve, a motor and a clamping block. The bidirectional threaded rod is arranged inside the placement seat, and the threaded sleeve is arranged on the outside of the bidirectional threaded rod. By setting the clamping structure in the present utility model, in order to prevent the zinc plate main body from moving randomly during slag scraping, through the use of the bidirectional threaded rod, the threaded sleeve and the clamping block, the zinc plate main body can be clamped and fixed, making the zinc plate main body more stable during slag scraping, thereby improving the clamping effect.

[0004] However, this device still has some problems. The device can effectively clamp and fix the zinc plate main body by using a bidirectional threaded rod, a threaded sleeve and a clamping block, thereby ensuring more stability during the slag scraping process and improving the clamping effect. However, in actual applications, since both sides of the zinc plate main body need to be processed during the slag scraping process, this device requires manual assistance to flip and re-clamp the galvanized sheet. This operation not only increases the complexity of manual operation, but also significantly reduces the subsequent processing efficiency because each flipping and clamping process takes additional time. Therefore, the manual flipping step directly affects the continuity and efficiency of the entire processing flow and reduces the automation level of production. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the output end of the flipping motor drives the lifting screw rod to rotate. The lifting screw rod drives the driving block to move downward. The driving block drives the lifting block to move downward. The lifting block drives the secondary rotating shaft to move downward. The secondary rotating shaft drives the fixing frame to move downward. The fixing frame drives the hot-dip galvanized plate body to move downward. During the downward movement of the lifting block, the extrusion block gradually approaches the lower guiding block and moves through the guiding opening formed on the surface of the lower guiding block. The extrusion block drives the L-shaped rod to move. The L-shaped rod drives the U-shaped dialing block to move, causing the U-shaped dialing block to move towards the secondary rotating shaft. The U-shaped dialing block drives the flipping gear to gradually approach the secondary rotating shaft, making the primary rotating shaft fit with the secondary rotating shaft and keeping the flipping gear and the flipping rack on the same vertical line. After the zinc slag scraping is completed, the lifting block resets upward. At this time, the lifting block drives the flipping gear to move upward through the primary rotating shaft and meshes with the flipping rack. At this time, the flipping gear starts to rotate, and drives the fixing frame to flip through the primary rotating shaft, the polygonal rod and the secondary rotating shaft. When the flipping gear completely disengages from the flipping rack, the fixing frame flips 180°, turning the side without zinc slag scraping to the lower side. At the same time, as the lifting block moves upward, the extrusion block passes through the guiding opening of the upper guiding block again, causing the flipping gear and the flipping rack to be misaligned, achieving the effect of automatically flipping the hot-dip galvanized plate body.

[0017] 2. In the present invention, the output end of the zinc scraping motor drives the driving screw rod to rotate. The driving screw rod drives the sliding block to move. The sliding block drives the scraping plate to move, scraping the zinc slag on the lower side of the hot-dip galvanized plate body attached to the scraping plate and removing the zinc slag on the surface. During the process of the scraping plate resetting after the zinc slag scraping is completed and the zinc scraping motor flips, the scraping plate drives the rotating gear to move. When the rotating gear moves, it rotates itself through the driving rack. The driving rack drives the adjusting block to move. The adjusting block drives the cleaning strip to move, causing the cleaning strip to clean the surface of the scraping plate and removing the zinc slag adhered to the surface of the scraping plate, achieving the effect of scraping the zinc slag on the hot-dip galvanized plate body and completing self-cleaning.

[0018] 3. In the present invention, when the lifting block moves downward, the lifting screw rod drives the transmission gear to rotate. The transmission gear drives the toothed rod to move. The toothed rod drives the connecting rod to move. The connecting rod drives the pull rod to move. The pull rod drives the piston to move, causing the piston to move away from the air delivery pipe. At this time, negative pressure is formed in the air box, and the air from the outside is inhaled into the air box through the one-way suction nozzle. When the lifting block moves to the lowest position, the piston reaches the maximum position. When the lifting block moves upward after the grinding is completed, the piston pushes back. At this time, the air in the air box starts to be delivered to the hollow plate through the air delivery pipe and is ejected through the multiple nozzles on the hollow plate. The gas blows the surface of the hot-dip galvanized plate body with zinc slag scraped, blowing away the fine zinc slag that is scraped off but still adheres to the surface, and blowing the zinc slag in the operation box into the collection dish, achieving the effect of secondary air blowing and cleaning of the hot-dip galvanized plate body.

[0021] The present invention will be further described below in conjunction with specific embodiments. However, those skilled in the art should understand that the detailed description given here in conjunction with the accompanying drawings is for better explanation. The structure of the present invention necessarily goes beyond these limited embodiments.

A flipping mechanism is fixedly installed on the inner wall of the operation box 2. A sliding opening is formed on one side of the operation box 2, and a slag scraping mechanism is slidably installed in the sliding opening; The flipping mechanism includes a mounting frame 9. The mounting frame 9 is fixedly installed on the inner wall of the operation box 2. A lifting groove is formed on one side of the mounting frame 9. A driving block 28 is slidably installed in the lifting groove. A lifting block 15 is fixedly installed on one side of the driving block 28. A rotating hole is formed on one side of the lifting block 15. A secondary rotating shaft 35 is rotatably installed in the rotating hole. A fixing unit is fixedly installed on one side of the secondary rotating shaft 35. A hot-dip galvanized sheet body 7 is installed on the fixing unit. A sliding hole is formed on one side of the secondary rotating shaft 35. A polygonal rod 34 is slidably installed in the sliding hole. One end of the polygonal rod 34 is fixedly installed with a primary rotating shaft 33. One end of the primary rotating shaft 33 is fixedly installed with a flipping gear 14. A flipping rack 13 is fixed on one side of the mounting frame 9. The flipping gear 14 meshes with the flipping rack 13. A sliding groove is formed on one side of the lifting block 15. An adjusting unit is slidably installed in the sliding groove; The slag scraping mechanism includes a sliding block 43. The sliding block 43 is slidably installed in the sliding opening. A scraping plate 12 is fixedly installed on one side of the sliding block 43. A driving hole is formed on one side of the operation box 2. A driving unit is rotatably installed in the driving hole. A sliding groove is formed on the lower side of the scraping plate 12. A cleaning unit is slidably installed in the sliding groove.

[0024] With the above structure, the horizontal plane of the operating box 2 is rectangular, and the flipping mechanism is installed on the inner wall of the longer side. The lifting block 15 slidingly installed in the lifting groove is driven by the driving block 28. The first-level rotating shaft 33 and the second-level rotating shaft 35 in the rotating hole of the lifting block 15 are the same size and are connected by a polygonal rod 34. The first-level rotating shaft 33 can be extended and retracted on one side of the second-level rotating shaft 35, so that the flipping gear 14 on one side of the second-level rotating shaft 35 can be adjusted to extend and retract, thereby realizing the switching of the vertical position with the flipping rack 13. The cross-section of the scraper 12 in the scraping mechanism is a right triangle. When the hot-dip galvanized plate body 7 is in contact with the scraper 12, it drives the sliding block 43 to move through the driving unit, and the sliding block 43 drives the scraper 12 to move, thereby scraping zinc slag from the surface of the hot-dip galvanized plate body 7.

[0025] Furthermore, the adjustment unit includes an L-shaped rod 30, which is slidably installed in the slide groove, and a U-shaped shift block 32 is fixedly installed at one end of the L-shaped rod 30, and an extrusion block 31 is fixedly installed at one end of the L-shaped rod 30. An upper extension rod 27 is fixedly installed on one side of the mounting frame 9, and an upper guide block 17 is fixedly installed on one end of the upper extension rod 27. A separation guide port is provided on one side of the upper guide block 17, and a lower extension rod 26 is fixedly installed on one side of the mounting frame 9, and a lower guide block 20 is fixedly installed on one end of the lower extension rod 26, and a merging guide port is provided on one side of the lower guide block 20.

[0026] With the above structure, the flip gear 14 is located in the U-shaped groove of the U-shaped shift block 32, and the other side of the U-shaped shift block 32 is connected by an L-shaped rod 30. The L-shaped rod 30 can move through the extrusion block 31 at the inflection point position in cooperation with the upper guide block 17 and the lower guide block 20, so that the U-shaped shift block 32 drives the flip gear 14 to adjust the position in the vertical direction. When the extrusion block 31 is displaced to the highest position, the flip gear 14 is staggered with the flip rack 13. When the extrusion block 31 is at the lowest position, the flip gear 14 and the flip rack 13 are located on the same vertical line, and when the flip gear 14 engages and rotates to the maximum position on the flip rack 13, the primary shaft 33 rotates exactly 180°.

[0027] Furthermore, a flip motor 16 is fixedly installed on the upper side of the mounting frame 9, a lifting hole is opened on the inner wall of the lifting groove, a lifting thread rod 29 is rotatably installed in the lifting hole, and the driving block 28 is screwed on the surface of the lifting thread rod 29. The output shaft of the flip motor 16 is coaxially fixedly connected to the top end of the lifting thread rod 29.

[0028] With the above structure, the flip motor 16 is a servo motor that can rotate forward and reverse. The output end of the flip motor 16 provides power to the driving block 28 through the lifting threaded rod 29.

[0029] Further, the driving unit includes a driving threaded rod 42. The non-threaded area on the surface of the driving threaded rod 42 is rotatably installed in the driving hole. A sliding block 43 is screwed and installed on the threaded area on the surface of the driving threaded rod 42. One side of the operation box 2 is fixedly installed with a zinc scraping motor 8. The output shaft of the zinc scraping motor 8 is coaxially and fixedly connected to one end of the driving threaded rod 42.

[0030] With the above structure, the zinc scraping motor 8 is a servo motor. The zinc scraping motor 8 drives the sliding block 43 to move horizontally through the driving threaded rod 42, providing power for the scraping plate 12.

[0031] Further, the cleaning component includes a cleaning strip 47. The cleaning strip 47 is slidably installed in the sliding groove. One side of the cleaning strip 47 is fixedly installed with an adjusting block 45. A transmission hole is opened on one side of the scraping plate 12.

The inner top wall of the sliding opening is fixedly installed with a driving rack 11. The driving rack 11 meshes with the rotating gear 44.

[0032] With the above structure, the cleaning strip 47 is attached to the scraping surface of the scraping plate 12 and is fixedly connected with a rotating gear 44 through a one-way rotating shaft. The one-way rotating shaft is a prior art. When the zinc scraping motor 8 rotates forward to perform the zinc slag scraping work, the one-way rotating shaft slips and does not provide power transmission for the rotating gear 44. When the zinc scraping motor 8 rotates in reverse to reset, at this time, the one-way rotating shaft provides power transmission for the rotating gear 44, thereby driving the cleaning threaded rod 46 to rotate.

[0033] Further, the fixing unit includes a fixing frame 5. The fixing frame 5 is fixedly installed at one end of the secondary rotating shaft 35. An adjusting groove is opened on the upper side of the fixing frame 5. A moving block 23 is slidably installed in the adjusting groove. An adjusting hole is opened on one side of the fixing frame 5. An installation screw rod 22 is rotatably installed in the adjusting hole. The moving block 23 is screwed and installed on the threaded area on the surface of the installation screw rod 22. An extrusion plate 24 is fixedly installed on the upper side of the moving block 23. A limiting block 10 is fixedly installed on one side of the fixing frame 5.

A stabilizing rod 48 is fixedly installed on the inner wall of the operation box 2.

[0034] With the above structure, the fixing frame 5 is rectangular, with card slots on both sides. The card slots can clamp and fix both sides of the hot-dip galvanized sheet body 7. The other side is L-shaped, blocking one side of the hot-dip galvanized sheet body 7. During installation, move the pressing plate 24 away from the fixing frame 5, then insert the hot-dip galvanized sheet body 7 through the card slots on both sides, and tighten the fixing frame 5 to complete the fixation of the hot-dip galvanized sheet body 7. When the fixing frame 5 drops to the lowest height, the L-shaped chamfers at one end of the stabilizing rods 48 on both sides of the inner wall of the operation box can limit both sides of the fixing frame to prevent the fixing plate 5 from shaking when scraping zinc slag.

[0035] Furthermore, an air box 21 is fixedly installed on the inner bottom wall of the base 1. A piston 37 is slidably installed on the inner wall of the air box 21.

A delivery port is opened on one side of the hollow plate 6, and the other end of the air delivery pipe 39 is fixedly installed in the delivery port. A one-way valve 38 is installed on the air delivery pipe 39. An air inlet hole is opened on one side of the air box 21, and a one-way suction nozzle 40 is fixedly installed in the air inlet hole.

[0036] With the above structure, the piston 37 fits in the air box 21. The upper side of the air box 21 is set as an inclined surface, which is convenient for conveying the zinc slag ejected through the nozzle 18 by the gas to the collecting dish 4. The hollow plate 6 is hollow inside, and equally spaced diversion holes are opened on its surface. A nozzle 18 is installed in each diversion hole. The one-way valve 38 installed on the air delivery pipe 39 fixedly connected to the other side of the hollow plate 6 has a flow direction from the air box 21 to the hollow plate 6, and the flow direction of the one-way suction nozzle 40 is from the outside to the inside of the air box 21.

[0037] Furthermore, one end of the pull rod 36 is fixedly installed with a connecting rod 19, and one end of the connecting rod 19 is fixedly installed with a toothed rod 41. The bottom end of the lifting threaded rod 29 is fixedly installed with a transmission gear 25, and the transmission gear 25 meshes with the toothed rod 41.

[0038] With the above structure, when the transmission gear 25 rotates, it drives the toothed rod 41 to move. The toothed rod 41 drives the connecting rod 19 to move, and the connecting rod 19 drives the piston 37 to move through the pull rod 36.

[0039] Furthermore, a box cover 3 is slidably installed on the upper side of the operation box 2. A pull-out port is opened on one side of the base 1, and a collecting dish 4 is slidably installed in the pull-out port.

[0040] With the above structure, the collecting dish 4 can collect the scraped zinc slag.

[0041] A hot-dip galvanized sheet includes a steel plate 701, the steel plate 701 is attached to the inner wall of the fixing frame 5, and galvanized layers 702 are provided on the upper and lower sides of the steel plate 701.

[0042] With the above structure, galvanized layers 702 with uniform thickness are plated on both the upper and lower sides of the steel plate 701 to prevent the steel plate 701 from corroding or rusting.

[0043] Working principle: When the device is in use, first manually open the box cover 3, then place the hot-dip galvanized sheet body 7 that needs to have zinc slag scraped on the fixing frame 5, and then manually rotate the mounting screw 22. The mounting screw 22 drives the moving block 23 to move, and the moving block 23 drives the pressing plate 24 to gradually approach the fixing frame 5 to press and fix the hot-dip galvanized sheet on the fixing frame 5, and then close the box cover 3; Start the flipping motor 16. The output end of the flipping motor 16 drives the lifting threaded rod 29 to rotate. The lifting threaded rod 29 drives the driving block 28 to move downward. The driving block 28 drives the lifting block 15 to move downward. The lifting block 15 drives the secondary rotating shaft 35 to move downward. The secondary rotating shaft 35 drives the fixing frame 5 to move downward. The fixing frame 5 drives the hot-dip galvanized sheet body 7 to move downward, so that the lower side of the hot-dip galvanized sheet body 7 is attached to the upper side of the scraping plate 12. At this time, stop the flipping motor 16 and start the zinc scraping motor 8. The output end of the zinc scraping motor 8 drives the driving threaded rod 42 to rotate. The driving threaded rod 42 drives the sliding block 43 to move. The sliding block 43 drives the scraping plate 12 to move, and scrapes the zinc slag on the lower side of the hot-dip galvanized sheet body 7 attached to the scraping plate 12 to scrape off the zinc slag on the surface. During the process that the scraping plate 12 completes scraping the zinc slag and the zinc scraping motor 8 flips and resets, the scraping plate 12 drives the rotating gear 44 to move. When the rotating gear 44 moves, it rotates itself through the driving rack 11. The driving rack 11 drives the adjusting block 45 to move. The adjusting block 45 drives the cleaning strip 47 to move, so that the cleaning strip 47 cleans the surface of the scraping plate 12 and scrapes off the zinc slag contaminated on the surface of the scraping plate 12; During the downward movement of the lifting block 15, the extrusion block 31 gradually approaches the lower guiding block 20 and moves through the guiding opening formed on the surface of the lower guiding block 20. The extrusion block 31 drives the L-shaped rod 30 to move, and the L-shaped rod 30 drives the U-shaped shifting block 32 to move, causing the U-shaped shifting block 32 to move towards the side of the secondary rotating shaft 35. The U-shaped shifting block 32 drives the flipping gear 14 to gradually approach the secondary rotating shaft 35, making the primary rotating shaft 33 fit with the secondary rotating shaft 35 and keeping the flipping gear 14 and the flipping rack 13 on the same vertical line. After the zinc slag scraping is completed, the lifting block 15 resets upward. At this time, the lifting block 15 drives the flipping gear 14 to move upward through the primary rotating shaft 33 and meshes with the flipping rack 13. At this time, the flipping gear 14 starts to rotate, and drives the fixing frame 5 to flip through the primary rotating shaft 33, the polygonal rod 34 and the secondary rotating shaft 35. When the flipping gear 14 completely disengages from the flipping rack 13, the fixing frame 5 flips 180°, turning the side without zinc slag scraping to the lower side. At the same time, as the lifting block 15 moves upward, the extrusion block 31 again causes the flipping gear 14 and the flipping rack 13 to be misaligned through the guiding opening of the upper guiding block 17. As the lifting block 15 moves downward again, the side without zinc slag scraping fits on the upper side of the scraping plate 12 and scrapes the slag on it, thus completing the automatic flipping of the hot-dip galvanized steel sheet body 7; When the lifting block 15 moves downward, the lifting screw rod 29 drives the transmission gear 25 to rotate. The transmission gear 25 drives the toothed rod 41 to move. The toothed rod 41 drives the connecting rod 19 to move. The connecting rod 19 drives the pull rod 36 to move. The pull rod 36 drives the piston 37 to move, causing the piston 37 to move away from the air delivery pipe 39. At this time, a negative pressure is formed in the air box 21, and the outside air is inhaled into the air box 21 through the one-way suction nozzle 40. When the lifting block 15 moves to the lowest end, the piston 37 reaches the maximum position. When the lifting block 15 moves upward after the grinding is completed, the piston 37 pushes back. At this time, the air in the air box 21 starts to be delivered to the hollow plate 6 through the air delivery pipe 39 and is ejected through the multiple nozzles 18 on the hollow plate 6. The gas blows the surface of the hot-dip galvanized steel sheet body 7 with zinc slag scraped, blows away the fine zinc slag that is scraped but still adheres to the surface, and blows the zinc slag in the operation box 2 into the collection dish 4; Finally, stop the slag scraping motor and the flipping motor 16, manually open the box cover 3, reverse-rotate the mounting bolts, and remove the hot-dip galvanized steel sheet body 7 to complete the zinc slag scraping of the hot-dip galvanized steel sheet body 7.
