Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of protective cleaning technology, and more specifically, to a sludge protective cleaning device for a leveling machine. Background Technology
[0002] During the operation of the leveling mill on a cold rolling continuous annealing line, a tension gauge roll, a stabilizing roll, and an anti-wrinkle roll are respectively installed at the inlet and outlet positions, totaling six rolls. During operation, due to the continuous high-speed friction and conveying of the strip on the roll surface, various impurities inevitably remain. These include metal shavings and dust particles floating in the production environment, as well as iron oxide scale that detaches from the strip surface during rolling. These impurities adhere to the roll surface and may embed into the strip surface, forming scratches, pits, and other defects, severely affecting the flatness of the strip surface. Utility Model Content
[0003] To overcome the above-mentioned defects, the embodiments of this disclosure provide a sludge protection and cleaning device for a leveling machine, which solves the technical problem in the prior art that residual impurities on the roller surface affect the flatness of the strip surface.
[0004] According to one aspect, at least one embodiment of this disclosure provides a sludge protection and cleaning device for a leveling machine, comprising:
[0005] A frame on which a bearing seat and a rotating roller are mounted, the rotating roller being rotatably mounted on the bearing seat;
[0006] A nozzle is movably mounted on the frame, and the nozzle sprays water to clean the rotating roller.
[0007] A protective cover is detachably mounted on the bearing seat, the protective cover having an isolation space within which the bearing seat is located, the isolation space being used to isolate the bearing seat from the rotating roller.
[0008] For example, in a leveling machine sludge protection and cleaning device provided in at least one embodiment of this disclosure, the protective cover includes:
[0009] A side guard plate is disposed on the bearing seat and surrounds the bearing seat;
[0010] A rear guard plate is disposed on the side guard plate and located on the side of the side guard plate near the rotating roller. The rear guard plate and the side guard plate are used to isolate the bearing seat and the rotating roller.
[0011] For example, in a leveling machine sludge protection and cleaning device provided in at least one embodiment of this disclosure, both ends of the side guard plate are provided with elastic plates, the shaft seat has a slot, and the elastic plate is used to snap into the slot.
[0012] For example, in a leveling machine sludge protection and cleaning device provided in at least one embodiment of this disclosure, the rear guard plate has a clearance groove, and after the elastic plate is inserted into the groove, the rotating roller is used to be inserted into the clearance groove.
[0013] For example, in a leveling machine sludge protection and cleaning device provided in at least one embodiment of this disclosure, the protective cover further includes:
[0014] A front guard plate is disposed on the side guard plate and located on the side of the side guard plate away from the rotating roller. The front guard plate and the rear guard plate are respectively located on both sides of the side guard plate. The front guard plate, the side guard plate and the rear guard plate form the isolation space.
[0015] For example, in a leveling machine sludge protection and cleaning device provided in at least one embodiment of this disclosure, the ends of the two elastic plates away from the side guard plate are respectively tilted in a direction away from each other to prevent the elastic plates from disengaging from the slots.
[0016] For example, in at least one embodiment of the present disclosure, a sludge protection and cleaning device for a leveling machine further includes:
[0017] A gasket is disposed on the frame, and a bearing seat is disposed on the gasket. A receiving space is formed between the bottom wall of the bearing seat, the upper end face of the gasket, and the end face of the frame.
[0018] A rotating plate is rotatably mounted on the elastic plate. The rotating plate is configured to be located within the receiving space after rotation and to be engaged with the bottom wall of the bearing seat to prevent the elastic plate from disengaging from the slot.
[0019] For example, in a leveling machine sludge protection and cleaning device provided in at least one embodiment of this disclosure, the rotating plate is threaded onto the gasket.
[0020] For example, in at least one embodiment of the present disclosure, a sludge protection and cleaning device for a leveling machine further includes:
[0021] A sliding block is slidably mounted on the frame along the axial direction of the rotating roller;
[0022] A swing block is oscillatingly mounted on the sliding block, and a nozzle is mounted on the swing block. The nozzle is configured to oscillate and then clean the surface of the rotating roller.
[0023] For example, in a leveling machine sludge protection and cleaning device provided in at least one embodiment of this disclosure, there are a plurality of rotating plates, and the plurality of rotating plates are spaced apart on the elastic plate.
[0024] The beneficial effects of the embodiments disclosed herein are as follows:
[0025] In this disclosure, the shaft seat is mounted on the frame and its stability can be ensured by bolt connection or other methods. The rotating roller is rotatably mounted on the shaft seat. After the nozzle moves, it can thoroughly clean impurities on the rotating roller. To prevent water from spraying onto the connection between the rotating roller and the shaft seat when cleaning impurities, thus diluting the lubricating oil between the rotating roller and the shaft seat, this disclosure uses a detachable method such as clips or bolts to install a protective cover on the shaft seat. This places the shaft seat within the isolation space of the protective cover, which seals the shaft seat and prevents water from hitting it. During the operation of the device, when there are oil stains, sludge, or other impurities on the surface of the rotating roller, the nozzle moves to a suitable position to spray water and clean the rotating roller.
[0026] The protective cover effectively prevents water from splashing onto the bearing seat while also preventing oil from splashing onto the strip steel, thus avoiding water contamination affecting the bearing seat's rotational performance and service life. This cover structure reduces equipment maintenance costs and downtime. The movable nozzle design allows for more comprehensive cleaning of the rotating roller, improving cleaning effectiveness.

[0039] like Figures 1-2As shown, this invention discloses a sludge protection and cleaning device for a leveling machine according to one embodiment. A bearing seat 2 is mounted on a frame 1 and its stability is ensured by bolt connections or other means. A rotating roller 3 is rotatably mounted on the bearing seat 2. The nozzle 4 moves to thoroughly clean impurities from the roller 3. To prevent water from spraying onto the connection between the roller 3 and the bearing seat 2 and diluting the lubricating oil between them, a protective cover 5 is detachably mounted on the bearing seat 2 using clips, bolts, or other removable methods. This places the bearing seat 2 within the isolation space 51 of the protective cover 5, which seals the bearing seat 2 and prevents water from hitting it. During operation, when the surface of the roller 3 has oil, sludge, or other impurities, the nozzle 4 moves to a suitable position to spray water and clean the roller 3.
[0040] The isolation space 51 of the protective cover 5 effectively prevents water from splashing onto the bearing seat 2, while also preventing oil stains on the bearing seat 2 from splashing onto the strip steel. This avoids the bearing seat 2 being affected by water, thus extending its rotational performance and service life. This protective cover 5 structure reduces equipment maintenance costs and downtime. The movable design of the nozzle 4 allows for more comprehensive cleaning of the rotating roller 3, improving the cleaning effect.
[0041] For example, such as Figure 2 As shown, the side guard plate 52 is mounted around the bearing seat 2, and can be fixed to the bearing seat 2 by welding, snap-fitting, or other methods. Then, the rear guard plate 53 is mounted on the side guard plate 52, and can also be connected by welding, bolts, or other methods. Ensure that the side guard plate 52 and the rear guard plate 53 are firmly installed, together serving to isolate the bearing seat 2 and the rotating roller 3. During installation, ensure that the side guard plate 52 completely covers the bearing seat 2 to prevent water from splashing onto it from above. The two ends of the rotating roller 3 rotate on the two bearing seats 2 respectively. Each bearing seat 2 is designed with a protective cover 5, and the nozzle 4 slides within the sliding space formed by the two rear guard plates 53.
[0042] The side guard plate 52 surrounds the shaft seat 2, and the rear guard plate 53 cooperates with the side guard plate 52 to form a relatively closed isolation structure, which can more effectively isolate the shaft seat 2 and the rotating roller 3, and reduce the impact of the water sprayed by the nozzle 4 on the shaft seat 2. The rear guard plate 53 and the side guard plate 52 adopt a split structure. This split design facilitates the manufacturing and installation of the cover 5, and reduces manufacturing costs and installation difficulty.
[0043] For example, such as Figure 2As shown, elastic plates 521 are machined at both ends of the side guard plate 52. The two elastic plates 521 are inclined and fixed at one end to the side guard plate 52, while the other ends are far apart. The elastic plates 521 can be made of a metal material with a certain degree of elasticity. A groove 21 is machined on the bearing seat 2. The size and shape of the groove 21 must match the elastic plates 521. When installing the guard 5, align the elastic plates 521 at both ends of the side guard plate 52 with the groove 21 of the bearing seat 2, and press firmly to bring the other ends of the two elastic plates 521 closer together and into the groove 21, thereby fixing the side guard plate 52 to the bearing seat 2.
[0044] The snap-fit design of the elastic plate 521 makes the installation and removal of the cover 5 more convenient and quick, without the need for complicated tools. When cleaning, replacement, or maintenance is required, the cover 5 can be quickly removed from the bearing seat 2, improving equipment maintenance efficiency. At the same time, the elasticity of the elastic plate 521 ensures a tight connection between the cover 5 and the bearing seat 2, enhancing the isolation effect.
[0045] For example, such as Figure 2 As shown, a clearance groove 531 is machined on the rear guard plate 53. The size and shape of the clearance groove 531 must be adapted to the rotating roller 3. After the elastic plate 521 is inserted into the slot 21, the rotating roller 3 is inserted into the clearance groove 531. During installation, it is necessary to ensure that there is an appropriate gap between the rotating roller 3 and the clearance groove 531 to avoid friction between the rotating roller 3 and the rear guard plate 53 during rotation.
[0046] The roller 3 will not be interfered with by the rear guard plate 53 during rotation. The clearance groove 531 further enhances the isolation effect of the guard plate 5 on the bearing seat 2, preventing water from splashing onto the bearing seat 2 from the gap between the rear guard plate 53 and the roller 3.
[0047] For example, such as Figure 2 As shown, after the side guard plate 52 is installed, the front guard plate 54 is installed on the side guard plate 52, which can be done by bolt connection, snap-fit, or other methods. After the front guard plate 54, side guard plate 52, and rear guard plate 53 are installed, they together form a closed isolation space 51, completely enclosing the bearing seat 2 within it. To prevent the front guard plate 54 from interfering with other components, a clearance groove 531 can also be provided on the front guard plate 54.
[0048] The addition of the front guard plate 54 makes the isolation space 51 more enclosed, further improving the protection of the bearing seat 2. It can more effectively prevent water from splashing onto the bearing seat 2, reduce water corrosion of the bearing seat 2, and extend the service life of the bearing seat 2.
[0049] For example, such as Figure 3As shown, the bearing seat 2 generally uses dry oil lubrication. However, during periods of high summer temperatures, or after prolonged continuous operation of the bearing 6, the lubricating oil on the bearing 6 may melt and flow out due to the rising temperature. The melted lubricating oil is easily splashed onto the surface of the cold-rolled strip when the roller 3 rotates, causing oil spot defects on the strip surface. These oil spot defects have a serious negative impact on the quality of the strip, significantly reducing the product qualification rate. Mounting holes 22 are machined on the bearing seat 2, and the dimensions of the mounting holes 22 must meet the installation requirements of the bearing 6. The bearing 6 is installed in the mounting holes 22, and interference fits or other methods can be used to ensure a secure connection between the bearing 6 and the mounting holes 22. The roller 3 is then installed on the bearing 6, allowing the roller 3 to rotate freely on the bearing seat 2 via the bearing 6.
[0050] The use of bearing 6 reduces the friction of the rotating roller 3 during rotation, improving its rotational efficiency and stability. Simultaneously, bearing 6 can withstand certain radial and axial loads, ensuring the normal operation of the rotating roller 3 during work. During the use of bearing 6, lubricating oil needs to be added inside. The protective cover 5 prevents the rotating roller 3 from overheating after prolonged operation, melting the lubricating oil, and causing it to splash onto the rotating roller 3 and the strip as it rotates.
[0051] For example, such as Figure 3 , Figure 4 As shown, a shim 7 is installed on the frame 1, which can be achieved using bolts or other methods. The bearing seat 2 is installed on the shim 7, creating a receiving space 71 between the bearing seat 2, the shim 7, and the frame 1. A rotating piece 8 is installed on the elastic plate 521, and the rotating piece 8 can be rotatably mounted on the elastic plate 521 via a pin or other means. After the protective cover 5 is installed, the rotating piece 8 is rotated to engage within the receiving space 71, further securing the protective cover 5 and preventing the elastic plate 521 from disengaging from the slot 21 as the roller 3 rotates.
[0052] The shim 7 allows for adjustment of the installation height and levelness of the bearing seat 2, ensuring the installation accuracy of the roller 3. The design of the receiving space 71 and the rotating plate 8 increases the connection stability between the protective cover 5 and the frame 1, preventing the protective cover 5 from loosening or shifting during equipment operation and improving the protective effect of the protective cover 5. Threads are machined on the rotating plate 8, and corresponding threaded holes are machined on the shim 7. After the rotating plate 8 is engaged in the receiving space 71, rotating the rotating plate 8 causes its threads to mate with the threaded holes on the shim 7, thus setting the threads of the rotating plate 8 on the shim 7 and further reinforcing the connection between the protective cover 5 and the frame 1. The thickness of the rotating piece 8 is the same as that of the elastic plate 521. The length of the rotating piece 8 is greater than the width of the slot 21. When the rotating piece 8 rotates, since its length cannot be removed from the slot 21, the tightness of the fit between the elastic plate 521 and the slot 21 can be strengthened. Several rotating pieces 8 are designed. When one rotating piece 8 cannot be locked in the slot 21 due to the vibration of the equipment, the other rotating pieces 8 can still play the locking effect to prevent the elastic plate 521 and the slot 21 from separating.
[0053] The threaded connection makes the connection between the cover 5 and the frame 1 more secure, effectively preventing the cover 5 from loosening under equipment vibration or external force. At the same time, the threaded connection also makes it easier for the elastic plate 521 to be snapped onto covers of different thicknesses, improving the equipment's versatility.
[0054] For example, such as Figure 1 As shown, a slide rail and other structures are installed on the frame 1. A sliding block 9 is slidably mounted on the slide rail along the axial direction of the rotating roller 3. The sliding block 9 can be driven by a motor, lead screw, or other drive mechanism. A swing block 10 is installed on the sliding block 9. The swing block 10 is oscillatingly mounted on the sliding block 9 via a pin or other means, with the pin's axis parallel to the axis of the rotating roller 3. A nozzle 4 is mounted on the swing block 10. By controlling the swing angle of the swing block 10, the nozzle 4 can swing to different positions to clean the surface of the rotating roller 3.
[0055] The design of the sliding block 9 and the swing block 10 makes the movement of the nozzle 4 more flexible, enabling it to thoroughly clean the entire surface of the roller 3. The nozzle 4 can adjust the cleaning position and angle according to the distribution of impurities on the surface of the roller 3, thus improving the cleaning effect and efficiency.
