[0002] During the production and processing of stainless steel strip, it needs to undergo hot rolling. After hot rolling, a large amount of iron oxide scale will exist on the surface of the stainless steel strip; after annealing, some iron oxide scale will also be generated on the surface of the strip; in addition, many tiny foreign matter will be left in the pickling operation. These defects will further appear in the cold rolling process. In order to remove these defects, a brushing device is needed to clean the steel surface.

[0003] However, the prior art still has the following disadvantages when scrubbing: 1. When brushing the steel strip continuously, the brush roller is easily damaged or a large amount of iron oxide scale is attached inside. In order to ensure the effect of subsequent brushing, the brush roller needs to be replaced. In the prior art, the replacement of the brush roller mostly relies on manual labor and corresponding lifting equipment to complete the replacement operation. This kind of replacement efficiency is very low, and additional lifting equipment is required, which increases the difficulty of replacement; 2. After the replacement, the brush roller needs to be manually cleaned of the iron oxide attached to it. Manual cleaning is time-consuming and laborious, which not only increases the labor intensity of the staff, but also has poor cleaning effect, resulting in a large amount of iron oxide remaining on the brush roller in the later stage.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Example 1: Reference Figure 1-Figure 4 , a roller changing mechanism, which is used in the field of scrubbing machines, has a structure mainly including a workbench 1, and a plurality of rotating rollers 6 and a scrubbing cylinder 7 arranged on the workbench 1. The scrubbing cylinder 7 is fixedly sleeved on the outer wall of the rotating roller 6, and is used to scrub metal parts. Below the workbench 1, a cleaning box 2 is provided, and the cleaning box 2 is used to clean the scrubbing cylinder 7. On the top of the workbench 1, a plurality of conveying rollers 3 are rotatably connected through a vertical plate, and these conveying rollers 3 are used to convey the metal parts to be scrubbed to one side for continuous scrubbing operations. In order to support the rotating roller 6, two support seats 4 are fixedly provided on the top of the workbench 1, and the two ends of the rotating roller 6 respectively pass through the two support seats 4, thereby ensuring that the rotating roller 6 can rotate stably.

[0021] Reference Figure 2 and Figure 8 In the cleaning box 2, a liquid storage pipe 32 is rotatably provided, and a plurality of nozzles 33 are provided on one side of the liquid storage pipe 32. When the liquid storage pipe 32 rotates, the nozzles 33 can spray water to perform a full range of cleaning treatment on the replaced scrubbing cylinder 7.

[0022] Reference Figure 1-Figure 5, in order to achieve the replacement of the rotating roller 6. Each set of replacement structure includes a sliding groove 5 arranged in the support seat 4, and an arc-shaped top plate 8 is slidably connected in the sliding groove 5. A first base 14 is fixedly connected to one side of the support seat 4, and a second base 15 is fixedly connected to one side of the cleaning box 2. The same screw rod 16 is rotatably connected to the side where the first base 14 and the second base 15 are close to each other. A guide rod 17 is fixedly connected to the bottom of the first base 14, and the bottom end of the guide rod 17 is fixedly connected to the top of the cleaning box 2 (a groove is provided at the top of the cleaning box 2, and the bottom end of the guide rod 17 is fixed in this groove to ensure that the lifting seat 18 is lowered to a height that can meet the requirements of placing the rotating roller 6 in the placement groove 25). The outer wall sliding sleeve of the guide rod 17 is provided with a lifting seat 18 threadedly connected to the screw rod 16. When the motor drives the screw rod 16 to rotate, due to the limiting effect of the guide rod 17, the lifting seat 18 will rise and fall along the guide rod 17. One side of the lifting seat 18 is fixedly connected with an arc bottom plate 19, which is used to lift and lower the rotating roller 6. When the arc bottom plate 19 rises, it can drive the rotating roller 6 to rise together; when the arc bottom plate 19 falls, it can drive the rotating roller 6 to fall into the cleaning box 2. At this time, the arc top plate 8 and the arc bottom plate 19 cooperate to clamp the rotating roller 6, ensuring that the rotating roller 6 can rotate stably in the support seat 4.

[0023] Reference Figure 2-Figure 7 In addition, a rotating disk 24 is rotatably provided on the inner wall of one side of the cleaning box 2, and a plurality of placement grooves 25 are provided on the outer wall of the rotating disk 24 for placing the rotating roller 6. An annular plate 27 is rotatably provided on the outer wall of the rotating disk 24, and the annular plate 27 is fixed to the inner wall of one side of the cleaning box 2. The annular plate 27 cooperates with the rotating disk 24 to prevent the rotating roller 6 from being separated from the placement groove 25. An opening 28 is provided at the top of the annular plate 27, and the opening 28 is used to make way for the lifting and lowering of the rotating roller 6. When it is necessary to move the rotating roller 6 and the brush cylinder 7 into the cleaning box 2, the motor drives the rotating disk 24 to rotate, and the rotating disk 24 cooperates with the annular plate 27 to rotate the rotating roller 6 and the brush cylinder 7 to one side. When the rotating disk 24 rotates to a suitable position, the new rotating roller 6 and the brush cylinder 7 will move to the top, thereby completing the replacement of the rotating roller 6 and the brush cylinder 7.

[0024] Reference Figure 2 and Figure 8 In order to perform a more comprehensive cleaning process on the replaced scrubbing cylinder 7, a reciprocating cleaning structure is also provided in the cleaning box 2. The structure can drive the liquid storage tube 32 to reciprocate, so that the spray head 33 sprays and cleans the scrubbing cylinder 7 from different angles.

[0025] Reference Figure 2 , Figure 3 , Figure 6 , Figure 8 and Fig. 9The reciprocating cleaning structure includes a rotating shaft 29 rotatably arranged on the inner wall of one side of the cleaning box 2, and the rotating shaft 29 is located below the rotating disk 24. A rubber wheel 30 is fixedly sleeved on the outer wall of the rotating shaft 29, and the rubber wheel 30 is designed to be able to touch the outer wall of the rotating roller 6. When the rubber wheel 30 rotates, the rotating roller 6 can be driven to rotate together through the friction between the rubber wheel 30 and the rotating roller 6. In order to drive the rotating shaft 29 and the rubber wheel 30 to rotate, a second motor 31 is fixedly installed on one side of the cleaning box 2, and the output shaft of the second motor 31 is sealed and rotated to extend into the cleaning box 2, and is fixedly connected to the end of the rotating shaft 29 away from the rubber wheel 30. A residual gear 36 is also fixedly sleeved on the outer wall of the rotating shaft 29, and a moving frame 35 is slidably connected to the inner wall of one side of the cleaning box 2, and the moving frame 35 is designed to accommodate the residual gear 36 to slide inside it. The first racks 37 are fixedly connected to the top inner wall and the bottom inner wall of the movable frame 35, and these first racks 37 are intermittently meshed with the residual gears 36, that is, when the residual gears 36 rotate with the rotating shaft 29, they will alternately mesh and disengage with the first racks 37, and this meshing and disengagement process will drive the movable frame 35 to reciprocate on the inner wall of the cleaning box 2.

[0026] Reference Figure 8 and Fig. 9 A second rack 38 is fixedly connected to one side of the moving frame 35, and the second rack 38 is also slidably connected to the inner wall of one side of the cleaning box 2. A spur gear 39 is fixedly connected to the outer wall of the liquid storage tube 32, and the spur gear 39 is meshed with the second rack 38. Therefore, when the moving frame 35 and the second rack 38 reciprocate, they will drive the liquid storage tube 32 to reciprocate through the spur gear 39.

[0027] Reference Figure 8 In order to transport high-pressure liquid into the liquid storage pipe 32, a booster pump 34 is fixedly connected to the inner wall of the bottom of the cleaning box 2, and the liquid outlet of the booster pump 34 is connected to the liquid storage pipe 32 through a hose. In this way, when the liquid storage pipe 32 swings back and forth, the booster pump 34 can spray high-pressure water flow to the scrubbing cylinder 7 at different angles through the liquid storage pipe 32 and the nozzle 33, thereby removing the iron oxide impurities attached to the scrubbing cylinder 7.

[0028] Reference Figure 5An L-shaped support plate 10 is fixedly connected to one side of the arc-shaped top plate 8, and the top end of the L-shaped support plate 10 slides through the first base 14. This design can make the L-shaped support plate 10 more stable when lifting. A first motor 11 is fixedly connected to the top of one side of the L-shaped support plate 10. The output shaft of the first motor 11 rotates and penetrates the L-shaped support plate 10, and is fixedly connected to a first bevel gear 12. Second bevel gears 13 are fixedly connected to both ends of the rotating roller 6, and these second bevel gears 13 are meshed with the first bevel gear 12. Therefore, when the first motor 11 rotates, it will drive the rotating roller 6 and the scrubbing cylinder 7 to rotate together through the cooperation of the first bevel gear 12 and the second bevel gear 13.

[0029] Specifically, when the lifting seat 18 drives the arc bottom plate 19 to move upward, the rotating roller 6 and the scrubbing cylinder 7 will be moved back into the sliding groove 5. At this time, the cooperation between the arc bottom plate 19 and the arc top plate 8 can limit the rotating roller 6. At the same time, during the upward movement of the rotating roller 6, the first motor 11 will drive the first bevel gear 12 to rotate slowly, so that the second bevel gear 13 can smoothly mesh with the first bevel gear 12 when the rotating roller 6 moves upward.

[0030] Reference Figure 5 and Figure 7 A plurality of annular limiting grooves 20 are provided on the outer wall of the rotating roller 6, and first semicircular rings 21 are fixedly connected to the top inner wall of the arc-shaped top plate 8 and the bottom inner wall of the arc-shaped bottom plate 19. The two first semicircular rings 21 extend into adjacent annular limiting grooves 20 respectively and slide with the annular limiting grooves 20. Such a design can limit the rotating roller 6 to prevent it from deflecting during the rotation process.

[0031] Reference Figure 5 In addition, an arc-shaped stopper 22 is fixedly connected to the bottom of the L-shaped support plate 10, and the arc-shaped stopper 22 also extends into the adjacent annular stopper groove 20 to further stop the rotating roller 6. Through the cooperation of the first semicircular ring 21, the arc-shaped stopper 22 and the annular stopper groove 20, it can be ensured that the rotating roller 6 always remains stable during rotation without deviation.

[0032] Reference Figure 7 A plurality of placement grooves 25 are provided in the rotating disk 24, and the inner wall of each placement groove 25 is fixedly connected with a second semicircular ring 26. The design of these second semicircular rings 26 is to cooperate with the adjacent annular limiting grooves 20 to limit the rotating roller 6 together.

[0033] Specifically, when the rubber wheel 30 drives the rotating roller 6 to rotate, the second semicircular ring 26 and the annular limiting groove 20 are closely matched, so that the rotating roller 6 can be effectively prevented from deflecting, thereby ensuring its stability and accuracy during operation.

[0034] Reference Figure 3-Figure 5 Inside the workbench 1, a clearance groove 23 is designed. The main function of this clearance groove 23 is to provide enough space for the lifting and lowering of the rotating roller 6, the brush cylinder 7, the lifting seat 18, and the arc bottom plate 19. At the same time, inside the support seat 4, a screw rod 9 is threaded through. The bottom end of the screw rod 9 is rotatably connected to the top of the arc top plate 8. By rotating the screw rod 9, the height of the arc top plate 8 can be controlled. Since the L-shaped support plate 10 is connected to the arc top plate 8, the rotation of the screw rod 9 will also drive the L-shaped support plate 10 and the first bevel gear 12 connected thereto to rise and fall together.

[0035] Specifically, the rotating roller 6 can be limited by the cooperation of the arc-shaped top plate 8 and the arc-shaped bottom plate 19, and the height of the scrubbing cylinder 7 can be adjusted according to actual needs to adapt to the scrubbing of metal parts of different heights.

[0036] Through the above-mentioned specific implementation, the stability and accuracy of the roller changing mechanism of the heavy-duty scrubber can be ensured during operation. At the same time, the height of the scrubber cylinder 7 can be adjusted according to actual needs, and the bristles can be effectively cleaned, thereby improving the overall scrubbing efficiency and cleaning effect.

[0037] In summary, the roller changing mechanism of the heavy-duty scrubber realizes the functions of automatic lifting, rotation and reciprocating cleaning of the rotating roller 6 through ingenious mechanism design, which greatly improves the scrubbing efficiency and cleaning effect.

[0038] Example 2: Reference Fig.10 , an improvement on the basis of Example 1: a lead screw 41 is fixedly connected to one end of the rotating shaft 29 away from the second motor 31. The end of the lead screw 41 away from the rotating shaft 29 is rotatably connected to the inner wall of one side of the cleaning box 2. On the outer wall of the lead screw 41, a paddle 40 is threadedly sleeved. This paddle 40 is slidably set on the bottom inner wall of the cleaning box 2, and is used to paddle the bristles on the outer wall of the scrubbing cylinder 7. When the rotating shaft 29 rotates, it will synchronously drive the lead screw 41 to rotate. Due to the threaded fit between the lead screw 41 and the paddle 40, the rotation of the lead screw 41 will drive the paddle 40 to reciprocate linearly on the bottom inner wall of the cleaning box 2. When the nozzle 33 rinses the scrubbing cylinder 7, the reciprocating movement of the paddle 40 can paddle the bristles on the scrubbing cylinder 7, so that the iron oxide attached to the bristles can be more easily removed by the water flow, thereby improving the cleaning effect.

[0039] A method for using a roller changing mechanism of a heavy-duty scrubber includes the following steps: S1, the metal workpiece can be conveyed to one side through the conveying roller 3, and the first motor 11 drives the rotating roller 6 and the brush cylinder 7 to rotate through the cooperation of the first bevel gear 12 and the second bevel gear 13 to brush the workpiece. When the brush cylinder 7 and the rotating roller 6 need to be replaced, the motor drives the screw rod 16 to rotate, and the screw rod 16 drives the arc bottom plate 19 and the rotating roller 6 to move downward through the lifting seat 18, so that the rotating roller 6 and the brush cylinder 7 can be moved into the cleaning box 2 and placed in the placement groove 25. At this time, the second semicircular ring 26 extends into the corresponding annular limiting groove 20 to limit the rotating roller 6, and the disassembly of the rotating roller 6 is completed; S2, then, the screw rod 16 cooperates with the lifting seat 18 to drive the arc bottom plate 19 to move down to the bottom of the rotating roller 6, and then the motor drives the rotating disk 24 to rotate 90°, and the rotating disk 24 cooperates with the annular plate 27 to rotate the rotating roller 6 and the brush cylinder 7 to one side, and the cooperation between the rotating disk 24 and the annular plate 27 can prevent the rotating roller 6 from detaching from the rotating disk 24. After the rotating disk 24 rotates, a new batch of rotating rollers 6 can be moved upward, and the lifting seat 18 drives the arc bottom plate 19 to move upward, and the rotating roller 6 and the brush cylinder 7 can be moved back into the sliding groove 5. At this time, the cooperation between the arc bottom plate 19 and the arc top plate 8 can limit the rotating roller 6. At the same time, when the rotating roller 6 moves upward, the first motor 11 drives the first bevel gear 12 to rotate slowly, so that the second bevel gear 13 is meshed with the first bevel gear 12 when the rotating roller 6 moves upward; S3. In addition, the lifting and lowering of the arc-shaped top plate 8 and the L-shaped support plate 10 can be controlled by the rotation of the screw rod 9, and the cooperation of the arc-shaped bottom plate 19 and the arc-shaped top plate 8 limits the rotating roller 6, so the height of the scrubbing cylinder 7 can be adjusted as needed, which is used to scrub metal parts of different heights; S4. When it is necessary to clean the replaced scrubbing cylinder 7, the second motor 31 drives the rotating shaft 29 and the rubber wheel 30 to rotate, and the rubber wheel 30 just touches the outer wall of the rotating roller 6. The friction between the rubber wheel 30 and the rotating roller 6 drives the rotating roller 6 and the scrubbing cylinder 7 to rotate. The rotating shaft 29 drives the moving frame 35 and the second rack 38 to move back and forth through the cooperation of the residual gear 36 and the first rack 37. The cooperation of the second rack 38 and the spur gear 39 drives the liquid storage tube 32 to swing back and forth, and then the booster pump 34, the liquid storage tube 32 and the nozzle 33 can spray high-pressure water flow to the scrubbing cylinder 7 at different angles to remove the iron oxide impurities attached to the scrubbing cylinder 7. S5. In addition, the rotating shaft 29 can synchronously drive the lead screw 41 to rotate, and the cooperation between the lead screw 41 and the paddle plate 40 drives the paddle plate 40 to move back and forth in a straight line. When the nozzle 33 flushes the brush cylinder 7, the paddle plate 40 can move the bristles on the brush cylinder 7, so that the water flow can remove the iron oxide attached to the bristles, thereby improving the cleaning effect.
