Description

Technical Field

[0001] This application relates to the technical field of immersion rolls, and in particular to an immersion roll scraper device. Background Art

[0002] The immersion roll in the zinc pot is in direct contact with the strip steel in the galvanizing process section. Due to the complex composition and high temperature of the zinc liquid in the zinc pot, a large amount of zinc slag is generated when iron elements are introduced into the zinc liquid. These zinc slags adhere to the immersion roll in the zinc pot, and a scraper is usually provided to clean the immersion roll.

[0003] Chinese Patent No. CN219648159U discloses an immersion roll scraper device, which includes a bracket and an immersion roll. The immersion roll is rotatably connected to the bracket. It also includes a scraping component, which includes a connecting frame, a buffer rod and a scraper. The connecting frame moves axially along the immersion roll relative to the bracket. The buffer rod is slidably connected to the connecting frame along the radial direction of the immersion roll. The scraper is detachably connected to the end of the buffer rod away from the connecting frame. The end of the scraper away from the buffer rod is in contact with the surface of the immersion roll, which has the beneficial effects of reducing the hard collision between the scraper and the immersion roll, reducing the possibility of damage to the scraper itself, and at the same time reducing the scratches on the surface of the immersion roll.

[0004] In the related art, the immersion roll is rotated to scrape the scraper in the circumferential direction of the roll body, and the position of the scraper in the length direction of the roll body is adjusted by moving the scraper. Therefore, the position of the scraper needs to be continuously adjusted, which affects the working efficiency. Utility Model Content

[0005] In order to reduce the adverse impact on the working efficiency, this application provides an immersion roll scraper device.

[0006] The immersion roll scraper device provided by this application adopts the following technical solutions:

[0007] An immersion roll scraper device includes a frame body and a clamping component installed on the frame body and clamping the roll body. On the upper side of the frame body, there are scrapers located on both sides of the roll body. The side of the scrapers close to each other is provided with a tip and is in contact with the side wall of the roll body. The frame body is provided with a moving component for driving the scraper to move along the length direction of the roll body and an adjusting component for adjusting the position of the scraper in the circumferential direction of the roll body.

[0008] By adopting the above technical solutions, the roll body is clamped on the frame body by the clamping component. At this time, the scrapers are located on both sides of one end of the roll body. The moving component is used to drive the scraper to move along the length direction of the roll body. When the scraper moves to the other end of the roll body, the adjusting component is used to adjust the position of the scraper in the circumferential direction of the roll body, and the moving component is used to drive the scraper to move in the length direction of the roll body until the scraping is completed. Thus, the possibility of driving the roll body to rotate and adjusting the position of the scraper in the length direction of the roll body is reduced, and the adverse impact on the working efficiency is reduced.

[0009] Optionally, the adjusting assembly includes an adjusting ring that can be sleeved outside the roller body and has an inner diameter greater than the diameter of the roller body. The scrapers are all located inside the adjusting ring and are oppositely arranged on both sides of the adjusting ring. A rotating ring is sleeved and rotatably connected to the outside of the adjusting ring, and a rotating member for driving the adjusting ring to drive the scraper to rotate circumferentially along the roller body is provided on the rotating ring.

[0010] By adopting the above technical solution, the rotating member drives the adjusting ring to rotate relative to the rotating ring, so as to drive the scraper to rotate circumferentially along the roller body through the adjusting ring, thereby reducing the possibility of driving the roller body to rotate, facilitating the scraping of the zinc slag on the roller body to be completed, and reducing the adverse impact on work efficiency.

[0011] Optionally, the rotating member includes a toothed ring sleeved outside the adjusting ring and fixedly connected to the adjusting ring. A gear is rotatably connected to the outside of the rotating ring. One side of the gear passes through the side wall of the rotating ring and meshes with the toothed ring, and a first motor for driving the gear to rotate is installed on the rotating ring.

[0012] By adopting the above technical solution, the first motor drives the gear to drive the toothed ring to rotate. At this time, the adjusting ring fixedly connected to the toothed ring drives the scraper to rotate circumferentially along the roller body, so as to facilitate the adjustment of the position of the scraper circumferentially along the roller body, facilitate the scraping of the zinc slag on the roller body to be completed, and reduce the adverse impact on work efficiency.

[0013] Optionally, the moving assembly includes a moving rod fixedly connected to the upper side of the rotating ring. The upper end of the frame body is penetrated and fixedly connected with a guide rod arranged along the length direction of the frame body. The moving rod is sleeved on the guide rod and is slidably connected to the guide rod. A lead screw parallel to the guide rod is penetrated and rotatably connected to the frame body. The lead screw passes through the moving rod and is threadedly connected to the moving rod. One end of the lead screw is installed with a second motor fixedly connected to the frame body.

[0014] By adopting the above technical solution, the second motor drives the lead screw to rotate and drives the moving rod to drive the rotating ring, the adjusting ring and the scraper to move along the length direction of the roller body. At this time, the moving rod slides on the guide rod, and the guide rod guides the moving rod and limits the possibility of the moving rod rotating, facilitating the driving of the scraper to move and scrape the zinc slag circumferentially on the roller body, and reducing the adverse impact on work efficiency.

[0015] Optionally, springs are fixedly connected to the middle parts of the mutually remote sides of the scrapers, and the mutually remote ends of the springs are fixedly connected to the side wall of the adjusting ring.

[0016] By adopting the above technical solution, when the zinc slag adhered to the roller body is difficult to clean, the zinc slag drives the scraper to move away from the roller body. At this time, the spring is compressed, thereby buffering the scraper and reducing the possibility of scraper damage. And when the scraper detaches from this zinc slag, the spring restores its deformation and makes the scraper fit against the side wall of the roller body again to scrape off the zinc slag, reducing the adverse impact on the service life of the scraper.

[0017] Optionally, brushes facing the side wall of the roller body are fixedly connected to both sides inside the adjusting ring. The brushes are located on both sides of the scraper, and both brushes can contact the side wall of the roller body.

[0018] By adopting the above technical solution, the scraper scrapes off the zinc slag on the side wall of the roller body. At this time, the brushes move with the scraper and clean the scraped zinc slag, further improving the working efficiency.

[0019] Optionally, the clamping assembly includes mounting seats located at both ends of the roller body and arranged oppositely. The end of the roller body can be inserted into the corresponding mounting seat. The mounting seat is slidably connected to the frame body. A hydraulic cylinder adapted to the mounting seat is fixedly connected to the frame body, and the telescopic rod of the hydraulic cylinder is fixedly connected to the corresponding mounting seat.

[0020] By adopting the above technical solution, the second motor drives the rotating ring to move to one end of the frame body through the lead screw, moves the roller body to be level with the height of the mounting seat. At this time, the second motor drives the rotating ring to move to be sleeved outside the roller body through the lead screw, the scraper contacts the side wall of the roller body, and the hydraulic cylinder drives the mounting seats to move towards each other until the end of the roller body is inserted into the corresponding mounting seat, facilitating the installation of the roller body on the frame body and reducing the adverse impact on the working efficiency.

[0021] Optionally, the scraper is provided with an arc-shaped concave from both ends to the middle in a direction away from each other.

[0022] By adopting the above technical solution, the shape of the scraper enables the scraper to fit against the side wall of the roller body, further facilitating the scraping off of the zinc slag adhered to the side wall of the roller body and reducing the adverse impact on the working efficiency.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The roller body is clamped on the frame body through the clamping assembly. At this time, the scraper is located on both sides of one end of the roller body. The scraper is driven to move along the length direction of the roller body through the moving assembly. When the scraper moves to the other end of the roller body, the position of the scraper in the circumferential direction of the roller body is adjusted through the adjusting assembly, and the scraper is driven to move in the length direction of the roller body through the moving assembly until the scraping is completed, thereby reducing the possibility of driving the roller body to rotate and adjusting the position of the scraper in the length direction of the roller body, and reducing the adverse impact on the working efficiency;

[0025] 2. The first motor drives the gear to rotate. At this time, the adjusting ring fixedly connected to the gear ring drives the scraper to rotate circumferentially along the roller body, thereby facilitating the adjustment of the position of the scraper in the circumferential direction of the roller body, facilitating the completion of scraping the zinc slag on the roller body, and reducing the adverse impact on work efficiency.

[0026] 3. When the zinc slag adhered to the roller body is difficult to clean, the zinc slag drives the scraper to move away from the roller body. At this time, the spring is compressed, thereby buffering the scraper and reducing the possibility of scraper damage. And when the scraper disengages from this zinc slag, the spring restores its deformation and makes the scraper fit against the side wall of the roller body again to scrape the zinc slag, reducing the adverse impact on the service life of the scraper.

Detailed Description of the Embodiment

[0031] The following further details the present application with reference to the drawings.

[0032] The embodiment of the present application discloses a submerged roller scraper device. Referring to Figure 1 and Figure 2 , a submerged roller scraper device includes a vertical frame body 1. The roller body is horizontal and located below the frame body 1. A clamping component 2 for clamping the roller body is provided on the frame body 1. The clamping component 2 includes two mounting seats 21 oppositely arranged at the ends of the roller body. The side of each mounting seat 21 close to each other is provided with a mounting groove 211 adapted to the end of the roller body.

[0033] On both sides of the frame body 1, sliding grooves 11 are formed on the sides close to each other, and the ends far away from each other of the mounting seats 21 are inserted into the corresponding sliding grooves 11 and are slidably connected to the frame body 1. On the sides far away from each other of the side walls on both sides of the frame body 1, hydraulic cylinders 22 that are horizontal and face the roller body are fixedly connected, and the telescopic rods of the hydraulic cylinders 22 pass through the side walls of the prosthesis and are fixedly connected to the corresponding mounting seats 21.

[0034] Refer to Figure 1 and Figure 2 , on both sides of the roller body, scrapers 3 that are oppositely arranged and perpendicular to the length of the roller body are provided. On the sides close to each other of the scrapers 3, tips that contact the side wall of the roller body are provided, and the scrapers 3 are all arranged in an arc shape that is recessed in the direction away from each other from both ends to the middle. On the frame body 1, a moving component 4 for driving the scraper 3 to move along the length direction of the roller body and an adjusting component 5 for adjusting the position of the scraper 3 along the circumferential direction of the roller body are provided.

[0035] Refer to Figure 1 and Figure 2 , the adjusting component 5 includes a vertical adjusting ring 51 sleeved outside the roller body and having an inner diameter larger than the diameter of the roller body. The scrapers 3 are all located in the adjusting ring 51, and in the middle of the sides far away from each other of the scrapers 3, inserting rods 52 are fixedly connected. The ends far away from each other of the inserting rods 52 are inserted into the adjusting ring 51 and are slidably connected to the adjusting ring 51. Spring 53 are sleeved on the inserting rods 52. The ends close to each other of the spring 53 are fixedly connected to the corresponding scrapers 3, and the other ends are all fixedly connected to the inner side wall of the adjusting ring 51. The spring 53 is always in a compressed state.

[0036] Refer to Figure 1 and Figure 3 , on both sides inside the adjusting ring 51, annular brushes 6 are fixedly connected. The scrapers 3 are all located on the side close to each other of the brushes 6, and the side of the brush 6 away from the adjusting ring 51 contacts the side wall of the roller body. A rotating ring 54 is sleeved and rotatably connected to the outside of the adjusting ring 51, and a rotating member 55 for driving the adjusting ring 51 to drive the scraper 3 to rotate in the circumferential direction of the roller body is provided on the rotating ring 54.

[0037] The moving component 4 drives the rotating ring 54 to move to one end of the frame body 1, moves the roller body to be at the same height as the mounting seat 21. At this time, the moving component 4 drives the rotating ring 54 to move to be sleeved outside the roller body. The scraper 3 is located on both sides at one end of the roller body and contacts the side wall of the roller body. The hydraulic cylinder 22 is used to drive the mounting seat 21 to move towards each other until the end of the roller body is inserted into the corresponding mounting seat 21, which is convenient for installing the roller body on the frame body 1. The moving component 4 drives the scraper 3 to move along the length direction of the roller body. When the scraper 3 moves to the other end of the roller body, the rotating member 55 drives the adjusting ring 51 to drive the scraper 3 to rotate in the circumferential direction of the roller body, and the moving component 4 drives the scraper 3 to move in the length direction of the roller body. The brush 6 moves with the scraper 3 and cleans the scraped zinc slag until the scraping is completed.

[0038] The shape of the scraping blade 3 is such that the scraping blade 3 fits against the side wall of the roller body. When the zinc slag adhered to the roller body is difficult to clean, the zinc slag drives the scraping blade 3 to drive the insertion rod 52 to move away from the roller body. At this time, the spring 53 is compressed and buffers the scraping blade 3, reducing the possibility of damage to the scraping blade 3. When the scraping blade 3 is separated from this zinc slag, the spring 53 restores its deformation and causes the scraping blade 3 to fit against the side wall of the roller body again and scrape the zinc slag, reducing the adverse effect on the service life of the scraping blade 3.

[0039] Refer to Figure 2 , the rotating member 55 includes a gear ring 551 sleeved outside the adjusting ring 51 and fixedly connected to the adjusting ring 51. A rotating groove 541 adapted to the gear ring 551 is provided on the inner side wall of the rotating ring 54. The gear ring 551 is inserted into the rotating groove 541 and is rotatably connected to the rotating ring 54. A vertical gear 552 is rotatably connected to one side of the outside of the rotating ring 54. One side of the gear 552 is inserted into the rotating groove 541 and meshes with the gear ring 551. A first motor 553 is fixedly connected to the rotating ring 54. The output shaft of the first motor 553 is fixedly connected to the axis of one side of the gear 552.

[0040] The first motor 553 drives the gear 552 to drive the gear ring 551 to rotate. At this time, the adjusting ring 51 fixedly connected to the gear ring 551 drives the scraping blade 3 to rotate circumferentially along the roller body, facilitating the adjustment of the position of the scraping blade 3 in the circumferential direction of the roller body, and thus facilitating the completion of scraping the zinc slag on the roller body.

[0041] Refer to Figure 1 , the moving assembly 4 includes a vertical moving rod 41 fixedly connected to the upper side of the outside of the rotating ring 54. The upper end of the moving rod 41 passes through and is slidably connected to a horizontal guide rod 42. The ends of the guide rod 42 are fixedly connected to the side wall of the frame body 1. A horizontal lead screw 43 rotatably connected to the frame body 1 is provided below the guide rod 42. The lead screw 43 passes through the moving rod 41 and is threadedly connected to the moving rod 41. And a second motor 44 fixedly connected to the side wall of the frame body 1 is installed at the end of the lead screw 43.

[0042] The second motor 44 drives the lead screw 43 to rotate and drives the moving rod 41 to drive the rotating ring 54, the adjusting ring 51 and the scraping blade 3 to move along the length direction of the roller body. At this time, the moving rod 41 slides on the guide rod 42. The guide rod 42 guides the moving rod 41 and restricts the possibility of the moving rod 41 rotating, facilitating the driving of the scraping blade 3 to move and scrape the zinc slag in the circumferential direction of the roller body.

[0043] The implementation principle of a submerged roll scraping device in an embodiment of this application is as follows: The second motor 44 drives the rotating ring 54 to move to one end of the frame body 1 through the lead screw 43, moves the roll body to the same height as the mounting seat 21. At this time, the rotating ring 54 is driven to move to be sleeved outside the roll body. The scraping blade 3 is located on both sides of one end of the roll body and contacts the side wall of the roll body. The mounting seat 21 is driven to move by the hydraulic cylinder 22 until the end of the roll body is inserted into the corresponding mounting seat 21. The scraping blade 3 is driven to move along the length direction of the roll body until it moves to the other end of the roll body. The first motor 553 drives the scraping blade 3 to rotate to the position on the circumferential direction of the roll body that has not been scraped. The scraping blade 3 is driven to move in the length direction of the roll body again. The brush 6 moves with the scraping blade 3 and cleans the scraped zinc slag until the scraping is completed.

[0044] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
