Description

Technical Field

[0001] This invention relates to the field of galvanized strip steel rolling technology, specifically to a cleaning device for work rolls used in galvanized strip steel processing. Background Technology

[0002] Metal rolling is one of the most important and commonly used methods of metal plastic processing. Its core principle is to use the pressure between two or more rotating rolls to cause the metal billet to undergo plastic deformation, thereby obtaining steel products with the required shape, size and properties. Galvanized steel strip with uniform thickness, flat surface and suitable strength can be obtained through the rolling process.

[0003] In the galvanized strip rolling process, the work roll is the core load-bearing and transmission component, used to support the strip and transmit rolling pressure, directly affecting the strip forming accuracy and surface quality. During the galvanizing process, zinc dross, oil stains and rolling debris easily adhere to the surface of the work roll. If it is not cleaned in time, it may not only scratch the surface of the strip and cause product defects, but may also accelerate the wear of the work roll and shorten its service life. Therefore, the work roll needs to be cleaned and maintained in a targeted manner.

[0004] Existing cleaning components for work rollers are cumbersome and inconvenient to use, and lack flexibility in position adjustment, making it difficult to adapt to work rollers of different widths and installation positions. Furthermore, the fixed cleaning method can easily create cleaning dead zones, and most of them are single cleaning structures with limited effectiveness in removing impurities. Some devices have complex transmission structures, high failure rates, and lack stable movement and cleaning mechanisms, making it impossible to balance comprehensive and efficient cleaning, and thus failing to meet the high-precision cleaning requirements of galvanized strip steel processing. Summary of the Invention

[0005] The purpose of this invention is to provide a cleaning device for work rolls used in the processing of galvanized strip steel, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cleaning device for work rolls used in galvanized steel strip processing, comprising a bearing base plate, a set of rolling mill bodies being provided at the right end of the top surface of the bearing base plate, roller conveyor belts being connected to both the left and right ends of the rolling mill bodies, and a set of straightening machine bodies being connected to the left end of the roller conveyor belt, a set of cutting machine bodies being connected to the left end of the straightening machine bodies via roller conveyor belts, and a set of leveling machine bodies being connected to the left end of the cutting machine bodies via roller conveyor belts. The rolling mill body includes a frame, work rolls, a working motor, and a cleaning chamber. Two sets of work rolls capable of rolling galvanized steel strip are provided inside the frame. A working motor capable of driving the work rolls is connected to the front end of the frame, and a cleaning chamber is provided at the bottom end of the frame. The bottom end of the lower work rolls extends to... The cleaning chamber contains a cleaning assembly, which includes a horizontal mechanism, a swing mechanism, and a reverse mechanism. A swing mechanism is connected to the top of the horizontal mechanism, and a reverse mechanism is connected to the top of the swing mechanism. The horizontal mechanism includes a base plate, a drive mechanism, and a second drive mechanism. The top surface of the base plate is connected to the first drive mechanism, and the top of the first drive mechanism is equipped with the second drive mechanism. The first drive mechanism includes a fixed panel, a lead screw, a transmission belt, and a drive motor. The top front and rear ends of the top surface of the base plate are each equipped with a fixed panel. The left and right ends of the opposite surfaces of the two fixed panels are each equipped with a lead screw. The front ends of both lead screws extend through to the front of the front fixed panel and are connected by a transmission belt. The front end of the left lead screw is connected to a drive motor.

[0007] By adopting the above technical solution, galvanized steel strip can be moved and transported along the roller conveyor belt, and processed sequentially through the main body of the rolling mill, the main body of the straightening machine, the main body of the cutting machine, and the main body of the leveling machine. The cleaning component cleans the working rollers inside the main body of the rolling mill. The drive motor in the cleaning component drives the transmission belt to drive two sets of lead screws to rotate synchronously, so that the drive mechanism moves horizontally back and forth along the two sets of lead screws. This provides a basis for the directional position adjustment of the subsequent cleaning position, ensuring smooth movement, high transmission accuracy, reliable structure, and adaptability to the cleaning needs of working rollers with different widths.

[0008] Preferably, the second driving mechanism includes a movable plate, a guide rail, a second lead screw, a movable block, a rotating rod, a connecting piece, a bevel gear, and a second driving motor. The top ends of the two sets of first lead screws are connected to a movable plate. The top middle of the movable plate is provided with a guide rail. The inner middle of the guide rail is connected to a set of second lead screws. The outer side of the second lead screw is connected to a movable block. The top right of the opposite surfaces of the two sets of fixed panels is connected to a rotating rod. The outer side of the rotating rod is provided with a connecting piece. The right end of the second lead screw extends through the left end of the connecting piece to the left end of the rotating rod and is connected to the rotating rod through two sets of bevel gears. The front end of the rotating rod extends through the front fixed panel and is connected to a second driving motor.

[0009] By adopting the above technical solution, the second drive motor drives the rotating rod to rotate, and the bevel gear realizes the power conversion between the vertical and horizontal directions, changing the transmission direction, driving the second lead screw to rotate in the guide rail, and then driving the moving block to move horizontally left and right along the guide rail. The structure is compact and the transmission efficiency is high. The left and right movement of the moving block is coordinated with the forward and backward movement of the first drive mechanism, which can realize the two-dimensional position adjustment of the swing mechanism in the horizontal plane. The adjustment range is wide and the precision is controllable, which can adapt to the cleaning needs of the working rollers in different installation positions.

[0010] Preferably, the swing mechanism includes a second base plate, a pad block, a third drive motor, a drive crank arm, vertical columns, and a guide arm. The top surface of the moving block is connected to a set of second base plates. A set of pad blocks is provided at the front end of the second base plate. A set of third drive motors is connected to the top of the pad blocks. A set of drive crank arms is connected to the rear end of the drive shaft of the third drive motor. A set of drive blocks is provided at the rear end of the drive crank arms. A set of vertical columns is provided at both the left and right ends of the top surface of the second base plate. The top ends of the two sets of vertical columns are connected by a set of guide arms.

[0011] By adopting the above technical solution, the drive motor three drives the drive arm to rotate around the drive shaft of the drive motor three. Through the drive block at the rear end of the drive arm, the rotational motion of the drive motor three is converted into the swinging power of the drive arm and the drive block by the drive arm transmission structure. This can drive the moving frame to move back and forth. The structure is simple and the power transmission is direct, providing a stable motion basis for the swing cleaning of the reverse mechanism.

[0012] Preferably, two sets of horizontal plates are provided at the middle of the opposite surfaces of the two sets of vertical columns, and a set of sliders is provided between the two sets of horizontal plates. A set of movable frames is connected to the front end of the slider.

[0013] By adopting the above technical solution, the slider can slide between two sets of horizontal plates, limiting the movement path of the moving frame, ensuring the accuracy of the moving frame's trajectory, reducing offset and swaying during movement, and improving movement stability.

[0014] Preferably, a set of guide blocks are installed on the outer side of the guide arm, a set of connecting arms are connected to the front end of the guide blocks, and a set of connecting buckles are provided at the bottom end of the connecting arms, the connecting buckles being fastened to the outer side of the movable frame.

[0015] By adopting the above technical solution, the guide block is sleeved on the outside of the guide arm, and the connecting arm is fixed to the moving frame through the connecting buckle. When the moving frame moves left and right, the guide block can be driven to slide along the guide arm through the connecting buckle and the connecting arm, so as to realize the synchronous movement of the guide block and the moving frame, ensure the linkage consistency between the moving frame and the guide block, and further improve the movement stability of the guide block.

[0016] Preferably, the reversing mechanism includes a mounting frame, a fourth drive motor, a drive compartment, a first cleaning wheel, and a second cleaning wheel. A set of mounting frames is connected to the top surface of the guide block. A set of fourth drive motors is provided at the front end of the mounting frame. The rear end of the drive shaft of the fourth drive motor extends through to the middle of the mounting frame and is connected to a set of drive compartments. The rear end of the drive compartment extends through to the rear end of the mounting frame and is sequentially connected to a first cleaning wheel and a second cleaning wheel.

[0017] By adopting the above technical solution, the drive motor four drives the drive chamber to rotate, which in turn drives the cleaning wheel one and the cleaning wheel two to rotate in opposite directions, thus cleaning the surface of the working roller. The dual-wheel design of the cleaning wheel one and the cleaning wheel two not only expands the coverage of the cleaning of the working roller surface, but also enhances the peeling and removal effect of the adhesive on the working roller surface by the opposite rotation of the cleaning wheel one and the cleaning wheel two, resulting in high cleaning efficiency.

[0018] Preferably, a set of rotating shafts is provided in the middle of the drive compartment, the rear end of the rotating shafts extends through to the rear end of the mounting frame and is connected to a set of cleaning wheels, a linkage mechanism is provided on the outer side of the rotating shafts corresponding to the position of the drive compartment, and a set of fixed inner sleeves is connected to the inner side of the drive compartment, and a guide groove is provided on the inner side of the fixed inner sleeves.

[0019] By adopting the above technical solution, the rotating shaft inside the drive chamber drives the second cleaning wheel to rotate, and the linkage mechanism realizes power transmission through the guide groove on the fixed inner sleeve, thereby driving the first cleaning wheel to rotate in the opposite direction, thereby enhancing the cleaning effect on the surface of the working roller.

[0020] Preferably, the linkage mechanism includes a fixed frame, a rotating sleeve, a rotating cylinder, a second guide groove, a sliding groove, a second slider, and a linkage rod. A set of fixed frames is connected to the rear end of the mounting frame. A set of rotating sleeves is provided at the rear middle of the fixed frame. The front end of the rotating sleeve extends through to the front middle of the fixed frame and is connected to a set of rotating cylinders. A second guide groove is provided on the outer side of the rotating cylinder. The left and right ends of the fixed frame extend into the drive compartment. Sliding grooves are provided on both the left and right sides of the fixed frame. A set of second sliders is provided in each sliding groove. A set of linkage rods is provided at the middle of each second slider.

[0021] By adopting the above technical solution, the guide groove on the fixed inner sleeve drives the linkage rod and the slider to move along the slide groove, and the guide groove on the rotating cylinder drives the rotating cylinder, the rotating sleeve and the cleaning wheel to rotate. By using the mechanical linkage structure, the two sets of cleaning wheels can be driven to rotate in opposite directions under a single drive source. The structure is compact and the transmission efficiency is high. The cleaning effect on the surface of the working roller can be improved by the opposite rotation of the cleaning wheel and the cleaning wheel.

[0022] Preferably, the linkage rod passes through the second slider, with its inner end extending into the second guide groove and its outer end extending into the first guide groove.

[0023] By adopting the above technical solution, the linkage rod passes through the second slider, with its inner end extending into the second guide groove and its outer end extending into the first guide groove. This enables the linkage effect between the rotating cylinder and the drive chamber. The bidirectional embedding design of the linkage rod ensures that the power transmission is smooth. The second slider and the guide groove work together to limit the movement trajectory of the linkage rod, ensuring the synchronicity and stability of the reverse transmission and improving the cleaning effect of the reverse rotating cleaning wheel.

[0024] Preferably, the rotating sleeve is rotatably connected to the middle of the fixed frame, and the rear end of the rotating sleeve is fixedly connected to the rotating cylinder.

[0025] By adopting the above technical solution, it is ensured that the rotating cylinder can rotate stably around the fixed frame, and the fixed frame provides stable and reliable support for the rotation of the rotating sleeve and the rotating cylinder.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. This invention utilizes a drive mechanism 1 and a drive mechanism 2 set in a horizontal mechanism. Through the cooperation of a drive motor 1 and a transmission belt, two sets of lead screws 1 can be driven to rotate synchronously, achieving stable forward and backward movement of the moving plate. Then, the drive motor 2 drives the rotating rod to rotate, and through the transmission of two sets of bevel gears, it drives the lead screw 2 to rotate, causing the moving block to move left and right. The cooperation of drive mechanism 1 and drive mechanism 2 realizes the horizontal two-dimensional position adjustment of the swing mechanism and the reverse mechanism. Compared with the problem of the single adjustment of the cleaning component in the prior art, this structure can be adapted to working rollers of different width specifications and different installation positions. Moreover, the double lead screw transmission structure can effectively ensure smooth movement and controllable precision, and can adapt to rolling equipment with different structures, greatly improving the versatility and adjustment flexibility of the cleaning component.

[0028] 2. This invention utilizes a swing mechanism located at the top of the moving block. The swing mechanism includes components such as a base plate, a pad, a drive motor, a drive crank arm, a vertical column, and a guide arm. The drive motor drives the drive crank arm to rotate in a circular motion. The drive block pushes the moving frame and the slider to slide left and right along the horizontal plate. At the same time, the connecting arm drives the guide block to swing synchronously along the guide arm. This converts the rotational motion of the drive motor into the reciprocating swing power of the guide block and the reverse mechanism. Compared with the existing fixed cleaning method, this structure effectively expands the cleaning coverage of the reverse mechanism on the surface of the working roller, improving the comprehensiveness of cleaning.

[0029] 3. This invention utilizes a reversing mechanism located at the top of the guide block. The reversing mechanism includes a mounting frame, a fourth drive motor, a drive chamber, a first cleaning wheel, and a second cleaning wheel. The fourth drive motor can rotate the drive chamber and the fixed inner sleeve. Through the first guide groove, the linkage rod is driven to slide along the groove of the second slider. Then, through the second guide groove, the rotating cylinder and the rotating sleeve rotate in the opposite direction, realizing the reverse operation of the two sets of cleaning wheels under a single drive source. Combined with the brush of the first cleaning wheel and the scraper of the second cleaning wheel, compared with the existing single cleaning method, it not only enhances the removal effect of impurities on the surface of the working roller, but also saves drive costs through the purely mechanical linkage structure. By utilizing reverse rotation and dual cleaning modes, it improves the removal efficiency and cleaning quality of impurities on the surface of the working roller. Attached Figure Description

[0043] Please see Figures 1-2This invention provides a cleaning device for work rolls used in processing galvanized steel strip, including a support base plate 4. A rolling mill body 5, capable of rolling galvanized steel strip, is located on the right end of the top surface of the support base plate 4. Roller conveyor belts 6 for transporting galvanized steel strip are connected to both ends of the rolling mill body 5. A straightening machine body 7 is connected to the left end of the left roller conveyor belt 6. A cutting machine body 8 is connected to the left end of the straightening machine body 7 via the roller conveyor belt 6. A leveling machine body 9 is connected to the left end of the cutting machine body 8 via the roller conveyor belt 6.

Working roll 52, working motor 53, and cleaning chamber 54. Two sets of working rolls 52 for rolling galvanized strip steel are installed inside the frame 51. The front end of the frame 51 is connected to a working motor 53 that can drive the working rolls 52 to move. A cleaning chamber 54 is provided at the bottom of the frame 51. The bottom end of the lower working roll 52 extends into the cleaning chamber 54. The lower working roll 52 can be cleaned through the cleaning chamber 54, which is beneficial to the normal use of the lower working roll 52. A cleaning component is provided in the cleaning chamber 54. The cleaning component can clean the outside of the working roll 52 inside the rolling mill body 5, which is beneficial to the long-term use of the working roll 52.

[0044] Specifically, the galvanized steel strip can be moved and transported along the roller conveyor belt 6, and processed sequentially through the rolling mill body 5, the straightening machine body 7, the cutting machine body 8, and the leveling machine body 9. The cleaning components in the cleaning chamber 54 clean the lower working roller body 52, which can effectively extend the service life of the working roller body 52.

[0045] Please see Figures 2-4 The cleaning assembly includes a horizontal mechanism 1, a swing mechanism 2, and a reversing mechanism 3. A set of swing mechanisms 2 is connected to the top of the horizontal mechanism 1, and a set of reversing mechanisms 3 is connected to the top of the swing mechanism 2. The horizontal mechanism 1 includes a base plate 11, a drive mechanism 12, and a drive mechanism 13. The top surface of the base plate 11 is connected to the drive mechanism 12, and the top of the drive mechanism 12 is equipped with the drive mechanism 13. The drive mechanism 12 includes a fixed panel 121, a lead screw 122, a transmission belt 123, and a drive motor 124. Both ends of the top surface of the base plate 11 are fixed. A set of fixed panels 121 are fixedly connected. A set of lead screws 122 are installed on the left and right ends of the opposite surfaces of the two sets of fixed panels 121. The front ends of the two sets of lead screws 122 extend through to the front of the front fixed panel 121 and are connected by a set of transmission belts 123. The transmission belts 123 can drive the two sets of lead screws 122 to rotate synchronously. A set of drive motors 124 is connected to the front end of the left lead screw 122. The drive motors 124 can drive the left lead screw 122 to rotate and drive the other set of lead screws 122 to rotate through the transmission belts 123.

[0046] Specifically, the drive motor 124 drives the transmission belt 123 to drive the two sets of lead screws 122 to rotate synchronously, so that the drive mechanism 13 can move horizontally back and forth along the two sets of lead screws 122. This provides a basis for the directional position adjustment of the subsequent cleaning position, ensuring smooth movement, high transmission accuracy, reliable structure, and adaptability to the cleaning needs of working rollers 52 with different widths.

[0047] Please see Figure 4 The second drive mechanism 13 includes a movable plate 131, a guide rail 132, a second lead screw 133, a moving block 134, a rotating rod 135, a connecting piece 136, a bevel gear 137, and a second drive motor 138. A movable plate 131 is connected to the top of two sets of lead screws 122. The left and right bottom ends of the movable plate 131 are provided with corresponding internal threaded holes for the lead screws 122. Rotation of the two sets of lead screws 122 can drive the movable plate 131 to move back and forth. A guide rail 132 is provided at the top center of the movable plate 131. A second lead screw 133 is installed in the middle of the guide rail 132. A moving block 134 is connected to the outer side of the second lead screw 133. The second lead screw 133 rotates... The rotating block 134 can move left and right along the guide rail 132. A set of rotating rods 135 are connected to the top right of the opposite sides of the two sets of fixed panels 121. A set of "L"-shaped connectors 136 are provided on the outside of the rotating rods 135. One end of the connector 136 is sleeved on the outside of the rotating rods 135 and can move back and forth along the rotating rods 135. The other end is connected to the right end of the guide rail 132. The right end of the lead screw 133 extends through the left end of the connector 136 to the left end of the rotating rod 135 and is connected to the rotating rod 135 through two sets of bevel gears 137. The rotation of the rotating rod 135 can drive the lead screw 133 to rotate through the meshing of the two sets of bevel gears 137.

[0048] Specifically, the second drive motor 138 drives the rotating rod 135 to rotate, and the bevel gear 137 realizes the power conversion between the vertical and horizontal directions, changing the transmission direction, and drives the second lead screw 133 to rotate in the guide rail 132, thereby driving the moving block 134 to move horizontally left and right along the guide rail 132. The structure is compact and the transmission efficiency is high. The left and right movement of the moving block 134 is coordinated with the forward and backward movement of the first drive mechanism 12, which can realize the two-dimensional position adjustment of the swing mechanism 2 in the horizontal plane. The adjustment range is wide and the precision is controllable, which can adapt to the cleaning needs of the working roller 52 in different installation positions.

[0049] Please see Figure 5The swing mechanism 2 includes a base plate 21, a pad 22, a drive motor 23, a drive crank arm 24, vertical columns 25, and a guide arm 26. A set of base plates 21 is fixedly connected to the top surface of the moving block 134. A set of pads 22 is fixedly connected to the front end of the base plate 21. A set of drive motors 23 is installed at the top of the pads 22. A set of drive crank arms 24 is connected to the rear end of the drive shaft of the drive motors 23. The drive motors 23 can drive the drive crank arms 24 to rotate around the drive motors 23. A set of drive blocks 241 is rotatably connected to the rear end of the drive crank arms 24. A set of vertical columns 25 is fixedly connected to both the left and right ends of the top surface of the base plate 21. The top ends of the two sets of vertical columns 25 are connected by a set of arc-shaped guide arms 26.

[0050] Specifically, drive motor 23 drives drive arm 24 to rotate around drive shaft of drive motor 23. Through drive block 241 at the rear end of drive arm 24, the rotational motion of drive motor 23 is converted into swinging power of drive arm 24 and drive block 241 by drive arm transmission structure. This can drive moving frame 253 to move left and right reciprocally. The structure is simple and the power transmission is direct, providing a stable motion basis for swing cleaning of reverse mechanism 3.

[0051] Please see Figure 5 Two sets of parallel horizontal plates 251 are provided at the middle of the opposite surfaces of the two sets of vertical columns 25. A set of sliders 252 is slidably connected between the two sets of horizontal plates 251. A set of movable frames 253 is fixedly connected to the front end of slider 252. The driving block 241 is embedded in the movable frame 253 and can move up and down in the movable frame 253. As the driving crank arm 24 rotates, it drives the movable frame 253 and slider 252 to slide between the two sets of horizontal plates 251.

[0052] Specifically, slider 252 can slide between two sets of horizontal plates 251 to limit the movement path of the moving frame 253, ensuring the accuracy of the moving trajectory of the moving frame 253, reducing offset and swaying during movement, and improving movement stability.

[0053] Please see Figure 6 A set of guide blocks 261 are sleeved on the outer side of the guide arm 26. The guide blocks 261 can move along the guide arm 26. A set of connecting arms 262 are hinged to the front end of the guide blocks 261. A set of connecting buckles 263 are fixedly connected to the bottom end of the connecting arms 262. The connecting buckles 263 are fastened to the outer side of the movable frame 253 and can move up and down on the outer side of the movable frame 253. When the movable frame 253 moves left and right, the guide blocks 261 can be pushed to move synchronously along the guide arm 26 through the cooperation of the connecting arms 262 and the connecting buckles 263.

[0054] Specifically, the guide block 261 is sleeved on the outside of the guide arm 26, and the connecting arm 262 is fixed to the moving frame 253 through the connecting buckle 263. When the moving frame 253 moves left and right, the guide block 261 can be driven to slide along the guide arm 26 through the connecting buckle 263 and the connecting arm 262, so as to realize the synchronous movement of the guide block 261 and the moving frame 253, ensure the linkage consistency between the moving frame 253 and the guide block 261, and further improve the movement stability of the guide block 261.

[0055] Please see Figure 7 The reverse mechanism 3 includes a mounting frame 31, a drive motor 32, a drive chamber 33, a first cleaning wheel 34, and a second cleaning wheel 35. A set of "U"-shaped mounting frames 31 is connected to the top surface of the guide block 261. A set of drive motors 32 is installed at the front end of the mounting frame 31. The rear end of the drive shaft of the drive motor 32 extends through to the middle of the mounting frame 31 and is connected to a set of drive chambers 33. The rear end of the drive chambers 33 extends through to the rear end of the mounting frame 31 and is connected to a set of first cleaning wheels 34 and second cleaning wheels 35 in sequence, which can drive the first cleaning wheels 34 and second cleaning wheels 35 to rotate. The first cleaning wheel 34 is equipped with a brush on its outer side, and the second cleaning wheel 35 is equipped with a scraper on its outer side. Through the two different cleaning methods of brush and scraper, impurities adhering to the surface of the working roll 52 during the rolling process can be effectively removed, thereby improving the cleaning effect of the working roll 52.

[0056] Specifically, the drive motor 32 drives the drive chamber 33 to rotate, which in turn drives the cleaning wheel 34 and the cleaning wheel 35 to rotate in opposite directions, thus cleaning the surface of the working roller 52. The dual-wheel design of the cleaning wheel 34 and the cleaning wheel 35 not only expands the coverage of the cleaning of the surface of the working roller 52, but also enhances the peeling and removal effect of the adhesive on the surface of the working roller 52 by the opposite rotation of the cleaning wheel 34 and the cleaning wheel 35, resulting in high cleaning efficiency.

[0057] Please see Figures 8-9 A set of rotating shafts 331 is fixedly connected to the middle of the drive compartment 33. The rear end of the rotating shafts 331 extends through to the rear end of the mounting frame 31 and is connected to a set of cleaning wheels 35. A linkage mechanism 332 is provided on the outer side of the rotating shafts 331 corresponding to the position of the drive compartment 33. A set of fixed inner sleeves 333 is fixedly connected to the inner side of the drive compartment 33. A guide groove 334 is opened on the inner side of the fixed inner sleeves 333. When the drive shaft of the drive motor 32 rotates, it can drive the drive compartment 33, the rotating shafts 331 and the fixed inner sleeves 333 to rotate synchronously.

[0058] Specifically, the rotating shaft 331 inside the drive chamber 33 drives the second cleaning wheel 35 to rotate, and the linkage mechanism 332 transmits power through the guide groove 334 on the fixed inner sleeve 333, thereby driving the first cleaning wheel 34 to rotate in the opposite direction, thereby enhancing the cleaning effect on the surface of the working roller 52.

[0059] Please see Figures 9-11 The linkage mechanism 332 includes a fixed frame 3321, a rotating sleeve 3322, a rotating cylinder 3323, a second guide groove 3324, a sliding groove 3325, a second slider 3326, and a linkage rod 3327. A set of "U"-shaped fixed frames 3321 are fixedly connected to the rear end of the mounting frame 31. A set of rotating sleeves 3322 is rotatably connected to the middle rear end of the fixed frame 3321. The rotating sleeves 3322 are sleeved on the outside of the rotating shaft 331. A first cleaning wheel 34 is connected to the rear end of the rotating sleeves 3322. Rotation of the rotating sleeves 3322 can drive the first cleaning wheel 34 to rotate synchronously. The front end of the rotating sleeves 3322 extends through to the middle front end of the fixed frame 3321 and is fixedly connected to a set of rotating cylinders 3323, ensuring that the rotating cylinders 3323 can rotate stably around the fixed frame 3321. The fixed frame 3321 provides stable and reliable support for the rotation of the rotating sleeves 3322 and the rotating cylinders 3323. A guide groove is provided on the outer side of the rotating cylinders 3323. The second 3324, the front left and right ends of the fixed frame 3321 extend into the drive compartment 33. The left and right sides of the fixed frame 3321 are provided with sliding grooves 3325. A set of sliders 3326 are slidably connected in the sliding grooves 3325. A set of linkage rods 3327 is provided in the middle of the sliders 3326. The linkage rods 3327 pass through the sliders 3326. The inner end of the linkage rods 3327 extends into the guide groove 3324 and the outer end extends into the guide groove 334. The linkage rods 3327 pass through the sliders 3326. The inner end extends into the guide groove 3324 and the outer end extends into the guide groove 334. This can realize the linkage effect between the rotating cylinder 3323 and the drive compartment 33. The bidirectional embedding design of the linkage rods 3327 ensures that the power transmission is smooth. The sliders 3326 and the sliding grooves 3325 cooperate to limit the movement trajectory of the linkage rods 3327, ensuring the synchronicity and stability of the reverse transmission and improving the cleaning effect of the reverse rotating cleaning wheel.

[0060] Specifically, the guide groove 334 on the fixed inner sleeve 333 drives the linkage rod 3327 and the slider 3326 to move along the slide groove 3325. The guide groove 3324 on the rotating cylinder 3323 drives the rotating cylinder 3323, the rotating sleeve 3322 and the cleaning wheel 34 to rotate. By using the mechanical linkage structure, the two sets of cleaning wheels can be driven to rotate in opposite directions with a single drive source. The structure is compact and the transmission efficiency is high. The cleaning effect on the surface of the working roller 52 can be improved by the opposite rotation of the cleaning wheel 34 and the cleaning wheel 35.

[0061] Working principle:

[0062] When processing galvanized steel strip, the raw material is first conveyed to the main body 5 of the rolling mill by a set of roller conveyor belts 6. It is then rolled by two sets of working rollers 52 in the main body 5 of the rolling mill. The rolled material is then conveyed to the main body 7 of the straightening machine by a set of roller conveyor belts 6 for straightening. After straightening, it is then sent to the main body 8 of the cutting machine by a set of roller conveyor belts 6 for cutting and segmenting. Finally, it is sent to the main body 9 of the leveling machine by a set of roller conveyor belts 6 for finishing.

[0063] Before cleaning the working roller 52, drive motor 124 and drive motor 238 are started according to the installation position of the working roller 52 on the rolling mill body 5. Drive motor 124 drives the two sets of lead screws 122 to rotate, causing the moving plate 131 to move back and forth. Drive motor 238 drives the rotating rod 135 and lead screw 233 to rotate, causing the moving block 134, the swing mechanism 2, and the reversing mechanism 3 to move left and right. Then, the cleaning assembly is placed on the bottom surface of the cleaning cavity 54, located at the bottom end of the working roller 52, so that the reversing mechanism 3 is opposite to the outside of the working roller 52. Then, drive motor 323 drives the drive arm 24 to rotate circumferentially, using the connecting arm 262 and The connecting plate 263 drives the guide block 261 and the reversing mechanism 3 to move left and right along the guide arm 26, expanding the cleaning range of the bottom of the working roller 52. At the same time, the drive motor 32 can directly drive the rotating shaft 331 and the cleaning wheel 35 to rotate, and through the linkage mechanism 332, the fixed inner sleeve 333 and the guide groove 334, drive the cleaning wheel 34 to rotate in the opposite direction. By utilizing the reverse rotation of the cleaning wheel 34 and the cleaning wheel 35, the cleaning effect on the working roller 52 is enhanced, the peeling effect of the material adhering to the outside of the working roller 52 during the rolling process is improved, the cleaning intensity is reduced, the cleaning efficiency is improved, and the normal use of the working roller 52 is guaranteed, which can effectively extend the service life of the working roller 52.

[0064] This invention provides a cleaning device for work rollers used in galvanized steel strip processing. Through a drive mechanism 12 and a drive mechanism 13 located in a horizontal mechanism 1, a drive motor 124 and a transmission belt 123 work together to drive two sets of lead screws 122 to rotate synchronously, achieving stable forward and backward movement of the moving plate 131. Then, a drive motor 138 drives a rotating rod 135 to rotate, which, via two sets of bevel gears 137, drives the lead screw 133 to rotate, causing the moving block 134 to move left and right. The cooperation of drive mechanism 12 and drive mechanism 13 enables horizontal two-dimensional position adjustment of the swing mechanism 2 and the reversing mechanism 3. Compared to existing technologies where the cleaning components have limited adjustment options, this structure can adapt to working rollers 52 of different widths and installation positions. Furthermore, the dual-screw drive structure effectively ensures smooth movement and controllable precision, significantly improving the versatility and adjustment flexibility of the cleaning components. The swing mechanism 2, located at the top of the moving block 134, includes components such as a base plate 21, a pad 22, a drive motor 23, a drive crank arm 24, a vertical column 25, and a guide arm 26. The drive motor 23 drives the drive crank arm 24 to rotate circumferentially, which in turn pushes the moving frame 253 and the slider 252 horizontally via the drive block 241. The plate 251 slides left and right, while the connecting arm 262 drives the guide block 261 to swing synchronously along the guide arm 26. This converts the rotational motion of the drive motor 23 into the reciprocating swinging power of the guide block 261 and the reversing mechanism 3. Compared with the existing fixed cleaning method, this structure effectively expands the cleaning coverage of the working roller 52 surface by the reversing mechanism 3, improving the comprehensiveness of cleaning. The reversing mechanism 3, which is set at the top of the guide block 261, includes components such as the mounting frame 31, the drive motor 32, the drive chamber 33, the cleaning wheel 34, and the cleaning wheel 35. The drive motor 32 can drive the drive chamber 3. 3 rotates with the fixed inner sleeve 333, and drives the linkage rod 3327 to slide along the slide groove 3325 of the slider 3326 through the guide groove 334. Then, the guide groove 3324 drives the rotating cylinder 3323 and the rotating sleeve 3322 to rotate in the opposite direction, realizing the reverse operation of the two sets of cleaning wheels under a single drive source. Combined with the brush of the cleaning wheel 34 and the scraper of the cleaning wheel 35, compared with the existing single cleaning method, it not only enhances the effect of removing impurities from the surface of the working roller 52, but also saves the drive cost through the pure mechanical linkage structure. The reverse rotation and dual cleaning mode improve the removal efficiency and cleaning quality of impurities on the surface of the working roller 52.
