Description

Technical Field

[0001] The utility model relates to the technical field of metal plate and strip production, in particular to a high-pressure strip cleaning device. Background Art

[0002] In the field of metal sheet and strip processing, cleaning is the most important technical means of improving strip surface cleanliness. The main cleaning process is generally divided into three parts: cleaning, squeezing, and drying. The cleaning process primarily uses cleaning fluids to remove foreign matter such as oil and dust from the strip surface through spraying and brushing. Utility model patent publication number CN212682063U describes a spray device for cleaning the surface of tension-corrected aluminum strip, belonging to the field of aluminum alloy strip surface cleaning. The device comprises a nozzle, a conduit, and a water tank. The nozzles and conduit are located within the water tank. The conduits are fixed to the water tank and mounted on the upper and lower sides of the aluminum strip, with at least one nozzle on each side. The nozzles are evenly fixed to the conduit through mounting holes. The nozzles are integrally structured, divided into an outlet and an inlet area, with multiple spray holes arranged side by side at the outlet end. The nozzles are positioned at a 45-degree angle to the aluminum strip, tilted in the opposite direction of the strip's travel, and the distance between the nozzles and the strip is 10 cm. This patented technical solution adopts the spray device of the above structure, which can wash away the aluminum ash or aluminum powder on the upper and lower surfaces of the aluminum strip, solving the problem of pitting and pitting on the surface of the aluminum alloy strip.

[0003] The aforementioned patents and existing online metal strip cleaning equipment often employ brush rollers and sprays on the upper and lower surfaces of a linearly conveyed metal strip. While relatively easy to deploy and simple in structure, the horizontally conveyed strip is prone to retaining water, dirt, and debris, making it difficult to clean thoroughly. Furthermore, this type of online cleaning equipment suffers from being relatively long, occupying a significant amount of space within the production line.

[0004] In order to overcome the above problems, a strip high-pressure brushing device is needed. Utility Model Content

[0012] Furthermore, the brush roller assembly also includes a side baffle and a limiting top screw, the side baffle is fixedly connected to the central axis of the brush roller and is located between the end face of the brush roller and the inner side wall of the frame, and the frame is provided with a long arc hole for making way at the position where the central axis of the brush roller passes; the threaded hole support of the limiting top screw is fixedly connected to the outer side wall of the frame, the limiting top screw is threadedly connected to the threaded hole of the threaded hole support and the inner end abuts against the side wall of the swing arm driving end.

[0016] Compared with the prior art, the beneficial technical effects of the present invention are:

[0017] This high-pressure strip cleaning equipment utilizes staggered rubber rollers (1 and 2) to convey the strip in a flipping motion, exposing the top and bottom surfaces of the strip for easy cleaning. A brush roller assembly and spray assembly are also installed to perform vertical scrubbing, leveraging the gravity flow of the cleaning fluid to remove dirt and debris from the strip surface. Furthermore, the S-shaped return bend in the strip conveyor maximizes the vertical space of the equipment, avoiding the need to occupy the length of the production line, making the production line more compact. Another important function of the S-shaped rubber rollers is to provide strong support during strip cleaning, ensuring the strip remains stable despite the high-pressure spraying and brushing. The liquid collection tank allows for recycling of the cleaning fluid, reducing material waste. This high-pressure strip cleaning equipment utilizes staggered rubber rollers to convey the strip to be cleaned in an S-shaped motion, effectively scrubbing the strip surface vertically, reducing residual dirt and debris, and reducing the length of the production line. The S-shaped rubber rollers provide stable support for the strip, preventing it from vibrating during scrubbing.

[0018] Furthermore, the rational coordination of the brush roller assembly, spray assembly, and squeeze roller assembly enables simultaneous spraying and brushing, with either the top or bottom surface undergoing two spraying rinses, one brushing, and one squeezing, resulting in superior cleaning performance. By positioning the top edge of rubber roller two higher than the bottom edge of rubber roller one, the strip is conveyed diagonally forward and upward between rubber rollers one and two. Cleaning fluid adhering to the top surface of the strip is removed at its lowest point by the brush roller assembly directly below, preventing it from being transported backwards. Similarly, by positioning the center gap of the clamping roller assembly higher than the bottom edge of rubber roller two, cleaning fluid adhering to the bottom surface of the strip is prevented from being transported backwards. By arranging the cylinder, swing arm, and rotating shaft to move the brush roller toward or away from the rubber roller, the brush roller maintains a certain distance from the rubber roller during initial threading, facilitating smooth threading. Furthermore, the brush roller can be flexibly omitted based on the specific material of the strip, such as when cleaning soft metal strips. By arranging the driving gear coaxially with the rotating shaft, the driving and driven gears remain engaged as the cylinder drives the brush roller toward or away from the rubber roller, preventing disengagement and tooth play. The side ends of the brush rollers are sealed by the combination of side baffles and long, arc-shaped holes to prevent splashing of cleaning fluid. A limit screw abuts the side wall of the swing arm drive end, allowing precise adjustment of the pressure between the brush roller and the rubber roller for optimal scrubbing results. The rubber roller skeleton, formed by the fixed connection of the roller and the axle, is lightweight and structurally stable, while the rubber coating prevents damage to the strip surface. A liquid spindle ring is installed on the axle to centrifugally spin the liquid, preventing the cleaning fluid from transferring outward along the axle. The addition of a brake allows for simultaneous and rapid braking of both rubber rollers, preventing damage to the strip during conveying stops. By adjusting the height of the sliding bearing seats at both ends of the upper clamping roller, the feeding gap between the lower and upper clamping rollers can be adjusted according to the thickness of the strip, ensuring that the residual cleaning liquid on the strip is squeezed out. By placing an adjustable thickness gasket at the bottom of the bearing seat of the lower clamping roller, the center height of the conveying strip can be guaranteed to be consistent with the rear equipment.

[0019] This new high-pressure strip scrubbing equipment utilizes rubber rollers to return the strip, fully exposing both the top and bottom surfaces for easy scrubbing. It primarily employs a vertical scrubbing method, which is beneficial for removing dirt and debris from the strip surface. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The core of the utility model is to provide a high-pressure strip brushing equipment, which uses upper and lower staggered rubber rollers to perform S-bend transportation on the strip to be cleaned, and can vertically brush the surface of the strip to reduce residual dirt and debris, while reducing the length of the production line occupied. The rubber rollers stably support the strip to prevent shaking during brushing.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

Therefore, they cannot be understood as limitations on the present invention.

[0031] With reference to the accompanying drawings, Figure 1 This is a schematic diagram of the main structure of the utility model strip high-pressure brushing equipment; Figure 2 This is a left-side structural schematic diagram of the utility model strip high-pressure brushing equipment; Figure 3 This is a schematic diagram of the top view of the strip high-pressure brushing equipment of the utility model; Figure 4 This is a schematic diagram of the cross-sectional structure of the middle rubber roller of the utility model; Figure 5 This is a schematic diagram of the cooperation between the rubber roller and the brush roller assembly in the utility model; Figure 6 This is a schematic diagram of the driving structure of the clamping roller group in the utility model.

[0032] In one embodiment, Figures 1 to 6 As shown, the present invention's high-pressure strip scrubbing equipment is used in metal strip production lines and is an in-line cleaning device, meaning it scrubs while production is ongoing. The equipment comprises a frame 1, along with an inlet roller 2, rubber roller 1 3, rubber roller 2 4, a clamping roller assembly, a brush roller assembly 7, and a spray assembly 8, arranged parallel to the frame 1. The frame 1 comprises a closed metal frame housing structure, with closed top covers 103 on either side. There are two or more sets of brush roller assemblies 7 and spray roller assemblies 8. The strip 18 to be scrubbed passes sequentially from front to back through the inlet roller 2, rubber roller 1 3, rubber roller 2 4, and clamping roller assembly. Rubber roller 1 3 and rubber roller 2 4 are staggered vertically. The spray assembly 8 and brush roller assembly 7 are located on the outside of rubber roller 1 3. The spray assembly 8 and brush roller assembly 7 are also located on the outside of rubber roller 2 4. The spray assembly 8 and brush roller assembly 7 clean the strip 18.

[0033] Specifically, if Figure 1 、 Figure 2 and Figure 5 As shown, the spray assembly 8 includes a spray pipe and nozzles. The spray pipe is positioned parallel to the rubber roller. Multiple nozzles within the spray pipe spray cleaning fluid toward the surface of the strip 18. The spray pipe is rotatable to adjust the spray angle. The high-pressure strip scrubbing apparatus of the present invention also includes a cleaning fluid supply unit that pumps cleaning fluid into the spray pipe.

[0034] Specifically, if Figure 2As shown, the cleaning liquid supply unit includes a liquid collecting tank 102, a filter and a pump group. The liquid collecting tank 102 is received at the bottom of the frame 1, the filter is arranged at the bottom of the liquid collecting tank 102 and is connected to the liquid inlet of the pump group, and the liquid outlet of the pump group is connected to the spray pipe.

[0035] By setting up rubber rollers 1 3 and 2 4 that are staggered up and down to convey the strip 18 in a flipping manner, the top and bottom surfaces of the strip 18 can be exposed respectively, which is convenient for brushing; at the same time, by using the brush roller assembly 7 and the spray assembly 8 set on the side to perform vertical brushing, the gravity flow of the cleaning liquid can be fully utilized to separate dirt, debris and other debris from the surface of the strip 18. Moreover, the S-shaped return bend to convey the strip 18 fully utilizes the space in the height direction of the equipment, avoids occupying the distance in the length direction of the production line, and makes the production line more compact. Another important function of the S-bend rubber rollers is to provide strong support for the strip 18 during cleaning, so that the strip 18 can maintain a stable forward motion under high-pressure spraying and brushing. By setting up the liquid collecting tank 102, the cleaning liquid can be recycled, reducing material waste. The utility model discloses a high-pressure strip brushing device, which adopts rubber rollers staggered up and down to perform S-bend conveying on the strip to be cleaned, and can vertically brush the surface of the strip, reduce residual dirt and debris, and at the same time reduce the length of the production line occupied. The rubber rollers stably support the strip to prevent shaking during brushing.

[0036] In a specific embodiment of the present invention, Figures 1 to 3 As shown, a brush roller assembly 7 is located directly behind rubber roller 1 (3), with two spray assemblies 8 positioned above and below this brush roller assembly 7. The brush roller assemblies 7 and spray assemblies 8 surrounding rubber roller 1 (3) all clean the top surface of the strip 18. A brush roller assembly 7 is located directly in front of rubber roller 2 (4), with two spray assemblies 8 positioned above and below this brush roller assembly 7. All brush roller assemblies 7 and spray assemblies 8 surrounding rubber roller 2 (4) clean the bottom surface of the strip 18.

[0037] Specifically, if Figure 1 As shown, the high-pressure strip cleaning equipment of the present invention also includes a squeeze roller assembly 17. One squeeze roller assembly 17 is positioned directly below rubber roller 1 (3), with a spray assembly 8 positioned behind it. These squeeze rollers 17 squeeze out any cleaning fluid adhering to the top surface of the strip 18. Another squeeze roller assembly 17 is positioned directly below rubber roller 2 (4), with a spray assembly 8 positioned in front of it. These squeeze rollers 17 squeeze out any cleaning fluid adhering to the bottom surface of the strip 18.

[0038] Specifically, if Figure 1 As shown, the top edge of the second rubber roller 4 is higher than the bottom edge of the first rubber roller 3, and the feeding center seam of the clamping roller group is higher than the bottom edge of the second rubber roller 4.

[0039] Through the rational coordination of the brush roller assembly 7, spray assembly 8, and squeeze roller assembly 17, simultaneous spraying and brushing are achieved, with either the top or bottom surface undergoing two spraying rinses, one brushing, and one squeezing, resulting in a more effective cleaning effect. By setting the top edge of rubber roller 2 4 higher than the bottom edge of rubber roller 1 3, the strip 18 is conveyed diagonally forward and upward between rubber rollers 1 3 and 2 4. Cleaning fluid adhering to the top surface of the strip 18 is removed at its lowest point by the brush roller assembly 7 directly below, preventing it from being transported backwards. Similarly, by setting the center seam of the clamping roller assembly higher than the bottom edge of rubber roller 2 4, cleaning fluid adhering to the bottom surface of the strip 18 is less likely to be transported backwards.

[0040] In a specific embodiment of the present invention, Figure 1 and Figure 5 As shown, the brush roller assembly 7 includes a cylinder 701, a swing arm 702, a rotating shaft 703, and a brush roller 704. The base of the cylinder 701 is mounted on the outer wall of the frame 1 via a pin and a hinge support 706. The hinge support 706 is bolted to the frame 1. The piston rod end of the cylinder 701 is pin-connected to the driving end of the swing arm 702. The swing arm 702 is rotatably connected to the outer wall of the frame 1 via a rotating shaft 703. The axis of the rotating shaft 703 is parallel to the brush roller 704. The ends of the central axis of the brush roller 704 are mounted on the working end of the swing arm 702. The cylinder 701 drives the brush roller 704 toward or away from the rubber roller 1 3 or the rubber roller 2 4.

[0041] Specifically, the present invention's high-pressure strip scrubbing equipment also includes a second motor 11, a driving gear 12, and a driven gear 13. The second motor 11 is mounted on a motor support on the drive side of the frame 1. The driven gear 13 is coaxially fixedly connected to one end of the central axis of the brush roller 704. The output shaft of the second motor 11 is coaxially fixedly connected to the driving gear 12, and the driving gear 12 and the driven gear 13 are meshed in opposite directions. The second motor 11 drives the brush roller 704 to rotate, and the direction of rotation of the brush roller 704 is opposite to the conveying direction of the strip 18. The driving gear 12 is arranged coaxially with the rotating shaft 703.

[0042] Specifically, if Figure 1 As shown, the structure of the squeeze roller assembly 17 is the same as that of the main body of the brush roller assembly 7, and the clamping rollers are also pressed and released by the swing of the cylinder. The difference is that the squeeze roller assembly 17 uses a pinch roller for squeezing instead of a brush roller, and does not require independent power input. It adopts a passive rotation mode, that is, it rotates with the rubber roller to squeeze the surface of the strip 18.

[0043] By configuring the cylinder 701, swing arm 702, and rotating shaft 703 to move the brush roller 704 toward or away from the rubber roller, during initial threading, the brush roller 704 is positioned a certain distance from the rubber roller, facilitating smooth threading. Furthermore, the brush roller 704 can be flexibly omitted based on the actual material of the strip 18, such as when cleaning a softer metal strip. By arranging the driving gear 12 coaxially with the rotating shaft 703, the driving gear 12 and the driven gear 13 remain in meshing during the process of the cylinder 701 driving the brush roller 704 toward or away from the rubber roller, preventing disengagement and tooth play.

[0044] In a specific embodiment of the present invention, Figure 1 and Figure 5 As shown, the brush roller assembly 7 also includes a side baffle 705 and a limiting screw 707. The side baffle 705 is fixedly connected to the central axis of the brush roller 704 and is located between the end face of the brush roller 704 and the inner side wall of the frame 1. The frame 1 has a long arc hole 104 at the position where the central axis of the brush roller 704 passes. The center of the long arc hole 104 coincides with the axis of the rotating shaft 703. The threaded hole support of the limiting screw 707 is fixedly connected to the outer side wall of the frame 1. The limiting screw 707 is threadedly connected to the threaded hole of the threaded hole support, and the inner end abuts the side wall of the driving end of the swing arm 702.

[0045] The side end of the brush roller 704 is closed by cooperating with the side baffle 705 and the long arc hole 104 to prevent the cleaning liquid from splashing out; by the limiting top screw 707 abutting against the side wall of the driving end of the swing arm 702, the precise adjustment of the pressing amount of the brush roller 704 and the rubber roller can be achieved, thereby achieving a better brushing effect.

[0046] In a specific embodiment of the present invention, Figure 3 and Figure 4 As shown, rubber roller 1 (3) comprises a roller 301, axles 302, a rubber layer 303, and a liquid-spinning ring 304. The two axles 302 are coaxially fixedly connected at both ends of roller 301 and connected to the sidewalls of frame 1 via bearing blocks. A radial support plate is provided within roller 301, to which the axles 302 are fixedly connected. The rubber layer 303 covers the outer cylindrical surface and end faces of roller 301, and the liquid-spinning ring 304 is coaxially mounted on the axles 302. Rubber roller 2 (4) has the same structure as rubber roller 1 (3).

[0047] Specifically, if Figure 2 and Figure 3As shown, the high-pressure strip scrubbing equipment of the present invention also includes a motor 9 and a brake 10. Motor 9 is mounted on a motor support on the drive side of the frame 1. Two motors 9 are connected to one end of the half-shafts 302 of rubber roller 1 (3) and rubber roller 2 (4) via couplings. A brake disc is coaxially mounted on the output shaft of motor 9. Brake 10 is a double-ended caliper capable of simultaneously braking both discs.

[0048] The framework of rubber roller 1 (3), formed by the fixed connection of roller 301 and axle 302, is lightweight and structurally stable. The rubber layer 303 protects the surface of strip 18 from damage. A liquid-spinning ring 304 is installed on axle 302 to centrifugally spin the liquid, preventing it from being transferred outward along axle 302. The addition of a brake 10 allows for simultaneous and rapid braking of rubber roller 1 (3) and rubber roller 2 (4), preventing them from competing and damaging the strip 18 during conveying stops.

[0049] In a specific embodiment of the present invention, Figure 1 、 Figure 3 and Figure 6 As shown, the clamping roller assembly includes a lower clamping roller 5, an upper clamping roller 6, a motor 3 14, a universal coupling 15, and a hydraulic cylinder 16. The lower clamping roller 5 and the upper clamping roller 6 are mounted on the frame 1 via bearing blocks at both ends. The two motors 3 14 are each connected to the shaft ends of the lower clamping roller 5 and the upper clamping roller 6 via a retractable universal coupling 15. The hydraulic cylinder 16 is fixedly connected head-down to the top of the frame 1. The piston rod of the hydraulic cylinder 16 is connected to the sliding bearing block 601 at the shaft end of the upper clamping roller 6. The sliding bearing block 601 can slide up and down along the vertical mounting slot of the frame 1.

[0050] Specifically, if Figure 6 As shown, the bottom of the bearing seats at both ends of the lower clamping roller 5 are padded with gaskets, and the height of the bearing seats of the lower clamping roller 5 can be changed by adjusting the thickness of the gaskets.

[0051] By adjusting the sliding bearing seats 601 at both ends of the upper pinch roller 6 in the height direction, the feeding gap between the lower pinch roller 5 and the upper pinch roller 6 can be adjusted according to the thickness of the strip 18, ensuring that the residual cleaning liquid in the strip 18 is squeezed out. By placing a shim with adjustable thickness at the bottom of the bearing seat of the lower pinch roller 5, the center height of the conveying strip 18 can be guaranteed to be consistent with the rear equipment.

[0052] The operating process of the present high-pressure strip scrubbing equipment is as follows: During normal scrubbing, rubber rollers 1 (3) and 2 (4) rotate at the same speed and in opposite directions, driven by their respective motors (9). The strip (18) is pulled from front to back through the guide roller (2), rubber roller (3), rubber roller (2) (4), and the clamping roller assembly. Directly behind rubber roller (3), two spray assemblies (8) spray and clean the top surface of the strip (18). Cylinder (701) is in the ejection position, driving brush roller (704) toward rubber roller (3) and into contact with the top surface of the strip (18). Motor (2) (11) drives brush roller (704) via drive gear (12) and driven gear (13). The counter-rotating brush rollers (704) brush the top surface of the reversely conveyed strip (18) to remove dirt. Directly below rubber roller 1 (3), a spray assembly 8 cleans the top surface of strip 18 from bottom to top. As strip 18 is conveyed diagonally forward and upward to the top edge of rubber roller 2 (4), a low point forms directly below rubber roller 1 (3). Here, a brush roller assembly 7 removes cleaning fluid, dirt, and debris adhering to the top surface of strip 18, preventing it from being conveyed backward. The spray assembly 8 and brush roller assembly 7 directly in front of and below rubber roller 2 (4) operate in the same manner as rubber roller 1 (3) and will not be further described here. When strip 18 diagonally enters the feed gap between the lower and upper clamping rollers 5 and 6 of the clamping roller group, the lower and upper clamping rollers 5 and 6 squeeze out the cleaning fluid from its surface before continuing its conveyance. During the cleaning process, the cleaning liquid that falls or splashes is guided by multiple water guide plates 101 in the inner cavity of the frame 1 and flows down to the liquid collection tank 102. After being filtered by the filter, it is re-supplied to the spray assembly 8 by the pump group for use.

[0053] In summary, the utility model of the high-pressure strip brushing equipment, by setting the upper and lower staggered rubber rollers 13 and 24 to carry out flipping conveyance of the strip 18, can expose the top and bottom surfaces of the strip 18 respectively, which is convenient for brushing; at the same time, vertical brushing is carried out by the brush roller assembly 7 and the spray assembly 8 arranged on the side, which can make full use of the gravity flow of the cleaning liquid to separate dirt, debris and other debris from the surface of the strip 18. Moreover, the S-shaped return bend to convey the strip 18 makes full use of the space in the height direction of the equipment, avoids occupying the distance in the length direction of the production line, and makes the production line more compact. Another important function of the S-bend rubber rollers is to provide strong support for the strip 18 during cleaning, so that the strip 18 can keep moving forward stably under the conditions of high-pressure spraying and brushing. By setting the liquid collecting tank 102, the cleaning liquid can be recycled, reducing material waste. The present high-pressure strip scrubbing equipment utilizes staggered rubber rollers to convey the strip to be cleaned in an S-curve, vertically scrubbing the strip surface and reducing residual dirt and debris. This reduces the length of the production line, while also providing stable support for the strip to prevent vibration during scrubbing. Furthermore, through the coordinated arrangement of the brush roller assembly 7, spray assembly 8, and squeeze roller assembly 17, the strip can be scrubbed simultaneously with spraying, with each top or bottom surface undergoing two spray rinses, one scrubbing, and one squeeze, resulting in superior cleaning results. By setting the top edge of rubber roller 2 4 higher than the bottom edge of rubber roller 1 3, the strip 18 is conveyed diagonally forward and upward between rubber rollers 1 3 and 2 4. Cleaning fluid adhering to the top surface of the strip 18 is removed at its lowest point by the brush roller assembly 7 directly below, preventing it from being transported backwards. Similarly, by setting the center gap of the clamping roller assembly higher than the bottom edge of rubber roller 2 4, cleaning fluid adhering to the bottom surface of the strip 18 is prevented from being transported backwards. By configuring the cylinder 701, swing arm 702, and rotating shaft 703, the brush roller 704 is moved toward or away from the rubber roller. During initial threading, the brush roller 704 is positioned a certain distance from the rubber roller, facilitating smooth threading. Furthermore, the brush roller 704 can be flexibly omitted based on the actual material of the strip 18, such as when cleaning softer metal strips. By arranging the driving gear 12 coaxially with the rotating shaft 703, the driving gear 12 and the driven gear 13 remain in meshing engagement during the cylinder 701-driven movement of the brush roller 704 toward or away from the rubber roller, preventing disengagement and tooth play. The side baffle 705 and the long arc hole 104 ensure that the side end of the brush roller 704 is sealed, preventing splashing of the cleaning fluid. By actuating the limiting screw 707 against the side wall of the swing arm 702 drive end, the pressure between the brush roller 704 and the rubber roller can be precisely adjusted, achieving a superior scrubbing effect. The rubber roller 3 skeleton formed by the fixed connection between the roller 301 and the half shaft 302 can be lightweight and have strong structural stability. The surface of the strip 18 is prevented from being damaged by the covering of the rubber layer 303; by installing a liquid-spinning ring 304 on the half shaft 302, the liquid is centrifugally spun to prevent the cleaning liquid from being transmitted outward along the half shaft 302.The addition of brake 10 allows for simultaneous and rapid braking of both rubber rollers 1 (3) and 2 (4), preventing them from competing with each other and damaging the strip 18 during conveying stops. The height adjustment of the sliding bearing blocks 601 at both ends of the upper clamping roller 6 allows for the feed gap between the lower and upper clamping rollers 5 and 6 to be adjusted to accommodate the varying thicknesses of the strip 18, ensuring that any residual cleaning fluid is squeezed out of the strip 18. A shim with adjustable thickness is placed under the bearing blocks of the lower clamping roller 5 to ensure that the center height of the conveying strip 18 is aligned with that of the equipment behind it.
