Description

Technical Field

[0001] The invention relates to the technical field of cleaning machinery, and in particular to a brushing roller structure and a roller replacement method. Background Art

[0002] The scrubbing roller is a widely used cleaning structure, with a roller body with bristles at its center, and the two ends are rotatably connected to the scrubbing device. During the scrubbing process, the scrubbing roller rotates continuously, and the bristles on it directly contact the items to be cleaned, which inevitably causes the bristles to wear and deform. For example, in the cold-rolled stainless steel production process, a scrubbing roller is needed to remove the iron oxide scale remaining on the surface of the strip. During the scrubbing process, the brush on the scrubbing roller is in direct contact with the strip, and the running speed of the strip is sometimes very high. The rubber layer and brush of the scrubbing roller will gradually wear during work, which directly affects the productivity of the entire production line, the quality of the product and the production cost. In order to ensure the cleaning effect, the scrubbing roller needs to be replaced at regular intervals, and the roller replacement method and roller replacement time directly affect the working efficiency and production efficiency of the whole machine.

[0003] During the replacement of the commonly used brush rollers, the transmission components (such as transmission gears and transmission belts) need to be disassembled before the brush rollers can be removed. Some brush rollers even need to have additional roller changing devices during replacement. Therefore, a lot of time and manpower are consumed during the replacement process. The roller changing device also brings additional cost burden. The long time taken to replace the brush rollers greatly affects the production efficiency.

[0004] The prior art also discloses easily replaceable rollers. For example, the patent with application number (CN201420748215.7) discloses a cast iron roller with easily replaceable rollers. Slip rings for clamping the roller and the mounting seat are provided at both ends of the roller. Although the transmission assembly does not need to be removed during disassembly, the clips at both ends need to be removed, and the disassembly process is still complicated. In addition, both sides need to be installed at the same time during installation, which requires multiple operations and is difficult to install.

[0005] Therefore, how to improve the structure of the scrubbing roller and increase the replacement efficiency of the scrubbing roller is a problem that needs to be solved urgently. Summary of the invention

[0006] The purpose of the present application is to solve the problem of inconvenient replacement of the brush roller in the prior art. Therefore, the present invention provides a brush roller structure and a roller replacement method. The brush roller is transmission-connected to the connecting flange through a spline shaft. A sleeve capable of wrapping the brush roller is provided on the outer side of the connecting flange, so that the brush roller can be stably inserted or pulled out, thereby realizing the transmission connection and disconnection between the spline shaft and the connecting flange. When disassembling, it is only necessary to remove the connection of the operating end of the brush roller, and the brush roller can be pulled out of the connecting flange from the operating end.

[0007] To achieve the above-mentioned object, in a first aspect, the present invention provides an easily replaceable brush roller, the brush roller being arranged on a brush frame, the brush roller comprising a roller body, and the two ends of the roller body respectively having a transmission side shaft head and an operation side shaft head;

[0008] The transmission side shaft head is connected to the output end of the transmission equipment through a transmission assembly;

[0009] The transmission assembly includes a flat key, a spline shaft and a connecting flange;

[0010] The transmission side shaft head is transmission-connected to one end of the spline shaft via the flat key, the other end of the spline shaft is transmission-connected to the connecting flange via the spline, and the connecting flange is transmission-connected to the output end of the transmission equipment via a flange-type coupling;

[0011] The outer periphery of the connecting flange is provided with a sleeve wrapping the transmission assembly and the transmission side shaft head; and the sleeve rotates with the connecting flange;

[0012] The roller body is rotatably arranged on the scrubbing machine frame through two mounting seats; the two mounting seats are respectively arranged on the outer surface of the sleeve and the outer surface of the operating side shaft head.

[0013] By adopting the above technical solution, the connecting flange assumes the transmission function and is connected to the output end of the transmission equipment. The sleeve and the connecting flange are fixed as a whole and are rotatably arranged on the mounting seat. Therefore, when the output end of the transmission equipment rotates, the connecting flange and the sleeve drive the entire brush roller to rotate on the mounting seat at the same time.

[0014] The transmission side shaft head is transmission-connected to the connecting flange via a spline shaft, and the torque is transmitted to the brush roller via the spline. Since the mounting seat supporting the brush roller is rotatably arranged on the sleeve, in actual operation, there is no need to disassemble the mounting seat at the transmission side shaft head. Only the mounting seat of the operating side shaft head needs to be disassembled, and then the entire brush roller can be pulled out of the sleeve, thereby releasing the transmission connection between the spline shaft and the connecting flange and realizing the disassembly of the brush roller. During installation, it is only necessary to insert the transmission side shaft head into the sleeve, align the splines between the spline shaft and the connecting flange, and then install the mounting seat of the operating side shaft head to complete the installation of the brush roller.

[0015] In some embodiments of the first aspect, the mounting seat includes a bearing, a bearing seat, a distance block and a connecting block, the bearing on the sleeve is wrapped around the outer surface of the sleeve, the bearing at the operating side shaft head is wrapped around the outer surface of the operating side shaft head, and the bearing seat is sleeved on the outer periphery of the bearing to support the bearing;

[0016] The outer ring surface of the bearing seat is provided with a threaded hole, one end of the connecting block is arranged on the scrubbing frame, and the other end is connected to the bearing seat by bolts;

[0017] The distance block is arranged between the connection block and the bearing seat, and is provided with a through hole for the bolt to pass through;

[0018] A transparent cover is fixed to the side of the bearing seat by bolts, and the transparent cover covers the bearing from the side.

[0019] By adopting the above technical scheme, the free rotation of the scrubbing roller can be realized through the bearing, and the bearing is connected to the scrubbing frame through the bearing seat and the connecting block, so that the scrubbing roller is fixed. In addition, a distance block is arranged between the bearing seat and the connecting block, and the installation position of the scrubbing roller can be adjusted by adjusting the thickness of the distance block.

[0020] In addition, the transparent cover covering the side of the bearing can protect the bearing from the side, and can also block the bearing from both sides to prevent the bearing from sliding out of the bearing seat.

[0021] In some embodiments of the first aspect, the connecting block has two parts, both of which are in an inverted "L" shape, and their lower ends are connected to the distance block by bolts, and an installation gap is formed between the upper part and the distance block for convenient installation.

[0022] By adopting the above technical solution, the connection block and the scrubbing machine frame can be installed more conveniently through the installation gap.

[0023] In some embodiments of the first aspect, the sleeve includes a first sleeve and a second sleeve; one side of the first sleeve is arranged on the connecting flange by bolts, and the other side of the first sleeve extends longitudinally and wraps the connecting position between the transmission side shaft head and the spline shaft, and the mounting seat is arranged on the outer surface of the first sleeve;

[0024] The second sleeve is further provided on the other side of the first sleeve via bolts. The second sleeve extends longitudinally and covers a portion of the operating side shaft head.

[0025] By adopting the above technical solution, the bearing sleeve is arranged outside the first sleeve, and the brush roller is supported by the first sleeve. Therefore, the first sleeve covers the connection position between the transmission side shaft head and the spline shaft, so that the first sleeve can support the transmission side shaft head and the spline shaft at the same time, reducing the vertical force between the two; the second sleeve extends a certain length and covers part of the operating side shaft head, which can limit the radial movement of the operating side shaft head during rotation, so that the axial connection between the operating side shaft head and the spline shaft is more horizontal, preventing radial deviation.

[0026] In some embodiments of the first aspect, the transmission side shaft head end is provided with an annular notch,

[0027] The connecting flange comprises an inner ring and an outer ring fixed to the outer surface of the inner ring;

[0028] The inner ring is arranged in the annular recess, the first sleeve covers the outer side of the inner ring, and the outer ring is provided with threaded holes so that the connecting flange is connected to the first sleeve by bolts.

[0029] By adopting the above technical solution, the first sleeve can also provide support for the connecting flange. Similarly, it can also reduce the vertical force between the two and prevent radial offset between the connecting flange and the spline shaft.

[0030] In some embodiments of the first aspect, one end of the spline shaft wraps around the transmission side shaft head, a shaft keyway is opened at the end of the transmission side shaft head, and a matching hub keyway is opened on the inner side of the spline shaft; the two are connected by a flat key to ensure consistent axial movement and convenient disassembly and assembly.

[0031] A spline groove is arranged on the outer side of the other end of the spline shaft, and a matching spline groove is arranged on the inner side of the connecting flange.

[0032] By adopting the above technical solution, torque is transmitted through the flat key and the spline, and connection and disassembly are convenient.

[0033] In some embodiments of the first aspect, an operating side pressure plate is further included, wherein the operating side pressure plate is disposed on the scrubbing frame and axially presses the operating side shaft head end.

[0034] The above technical solution can prevent the transmission connection between the transmission side shaft head and the spline shaft or the spline shaft and the connecting flange from falling off during the rotation process.

[0035] In a second aspect, the present invention further provides a method for replacing a brushing roller, using the easily replaceable brushing roller as described above, the steps of replacing include:

[0036] S1: Disassembling the mounting seat at the shaft head of the operating side;

[0037] S2: axially pulling the transmission side shaft head and the spline shaft out of the sleeve;

[0038] S3: Connect a new scrubbing roller to the spline shaft via a flat key, insert the drive side shaft head connected to the spline shaft into the sleeve, and align the splines.

[0039] By adopting the above technical solution, the scrubbing roller can be quickly replaced, thereby improving production efficiency.

[0040] In general, compared with the prior art, the beneficial effects of the present invention are as follows: when replacing the brush roller, there is no need to disassemble the transmission equipment such as the coupling on the transmission side, and the transmission side of the brush roller is changed to a split structure. When replacing, only the connection on the operating side needs to be loosened, and the brush roller body can be pulled out from the operating side to complete the disassembly, avoiding installation errors and safety hazards caused by disassembling the transmission equipment. The disassembly process is convenient, especially for the roller system that needs to be replaced frequently, which can effectively save the time of roller replacement and improve the overall production efficiency.

[0041] Other features and corresponding beneficial effects of the present application are described in the latter part of the specification, and it should be understood that at least some of the beneficial effects become obvious from the records in the specification of the present application.

[0051] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0052] Example

[0053] See also Figures 1 to 3 This embodiment provides a brushing roller structure, the brushing roller is arranged on a brushing frame, and the brushing roller comprises a roller body 2, and the two ends of the roller body 2 are respectively provided with a transmission side shaft head 3 and an operation side shaft head 1;

[0054] The transmission side shaft head 3 is connected to the output end of the transmission equipment through the transmission assembly;

[0055] The transmission assembly includes a flat key 8, a spline shaft 4 and a connecting flange 5.

[0056] One end of the spline shaft 4 is connected to the transmission side shaft head 3 through a flat key 8, and the other end is connected to the connecting flange 5 through a spline. The spline shaft 4 and the connecting flange 5 are matched by splines to relatively fix the axial positions of the two. When the spline shaft 4 moves axially and circumferentially, it drives the roller body 2 to move synchronously. The connecting flange 5 is connected to the output end of the transmission equipment through a flange coupling (not shown in the drawings).

[0057] A sleeve is provided on the connecting flange 5 to wrap the transmission assembly and the transmission side shaft head 3 ; and the sleeve rotates with the connecting flange 5 .

[0058] The roller body 2 is rotatably mounted on the scrubbing machine frame through two mounting seats; the two mounting seats are respectively arranged on the outer surface of the sleeve and the outer surface of the operating side shaft head 1.

[0059] It should be noted that in the prior art, the scrubbing roller is generally connected to the transmission device through a belt or gear. When disassembling the scrubbing roller, the connecting parts need to be removed. For example, when replacing the scrubbing roller in the prior art, the coupling, mounting seat and other structures need to be removed, which increases the replacement time. In addition, the transmission assembly generally requires professionals to use a specific installation method to install it. If the installation is not precise enough, it may reduce the overall service life, easily cause failures, and even bring safety hazards.

[0060] The present invention adopts a split setting, the scrubbing roller and the spline shaft 4 form a whole, the connecting flange 5, the sleeve and the mounting seat on the transmission side form another part, and the two parts are connected by splines. When disassembling the scrubbing roller, the spline shaft 4 is directly pulled out from the sleeve, which not only releases the transmission connection between the spline shaft 4 and the connecting flange 5, but also completes the disassembly of the transmission side. There is no need to disassemble the transmission assembly, the disassembly is quick, and the operation threshold is low; when installing, the transmission side shaft head 3 is inserted into the sleeve, and the scrubbing roller, the connecting flange 5 and the sleeve form a whole and rotate together. At the same time, in order to prevent this whole from detaching from the sleeve during the rotation process, an operating side pressure plate 14 is also provided at the operating side shaft head 1, which is used to axially press the end of the operating side shaft head 1.

[0061] In this embodiment, the scrubbing roller is connected to the scrubbing frame through two mounting seats, one mounting seat is arranged at the operating side shaft head 1, and the other mounting seat is arranged on the sleeve. When the scrubbing roller is connected to the connecting flange 5 through the spline shaft 4, the scrubbing roller, the connecting flange 5 and the sleeve form a whole, which is supported at both ends by the mounting seats respectively, and the whole rotates on the mounting seats.

[0062] Specifically, the brush roller is connected to the spline shaft 4 in the following manner: a shaft keyway is opened at the end of the transmission side shaft head 3 , a hub keyway is opened inside the spline shaft 4 , and the two are connected by a flat key 8 .

[0063] Specifically, the spline shaft 4 and the connecting flange 5 are connected in the following manner: a spline groove is provided on the outer side of the other end of the spline shaft 4, and a matching spline groove is provided on the inner side of the connecting flange 5. A longitudinal spline groove is provided on the inner cylindrical surface of the connecting flange 5, and the size thereof matches the spline groove on the outer cylindrical surface of the spline shaft 4. When installing and removing, the spline shaft 4 only needs to be inserted and withdrawn axially along the connecting flange 5.

[0064] Specifically, the sleeve includes a first sleeve 6 and a second sleeve 7; the first sleeve 6 and the second sleeve 7 are connected by bolts, one side of the first sleeve 6 is set on the connecting flange 5 by bolts, and the other side extends longitudinally and wraps the connecting position between the transmission side shaft head 3 and the spline shaft 4. An annular recess is provided at the end of the transmission side shaft head 3, and a part of the connecting flange 5 is provided in the annular recess, so that the first sleeve 6 can be simultaneously sleeved on the outside of the connecting flange 5, and can simultaneously support the spline shaft 4 and the connecting flange 5; a preferred implementation method is: the connecting flange 5 includes an inner ring and an outer ring fixed on the outer surface of the inner ring, and the outer ring is wider than the first sleeve 6, so the first sleeve 6 and the connecting flange 5 are fixed by a plurality of bolts arranged axially. In this way, the radial width can be reduced, making the rotation more labor-saving. On the other hand, the bolts arranged axially can better withstand the axial force.

[0065] One side of the second sleeve 7 is bolted to the first sleeve 6, and the other side extends longitudinally to cover a portion of the operating side shaft head 1, thereby reducing radial movement between the operating side shaft head 1, the spline shaft 4 and the connecting flange during rotation.

[0066] Specifically, the mounting seat includes a bearing 9, a bearing seat 10, a distance block 11 and a connecting block 12. The bearing 9 is wrapped around the outer surface of the sleeve or the operating side shaft head 1. The bearing seat 10 is sleeved on the outer periphery of the bearing 9 to support the bearing 9. A threaded hole is provided on the outer ring surface of the bearing seat 10. One end of the connecting block 12 is fixed to the scrubbing machine frame, and the other end is connected to the bearing seat 10 by bolts. Preferably, the connecting block 12 has two parts, both of which are in an inverted "L" shape, and the lower ends thereof are connected to the distance block 11 by bolts. An installation gap is formed between the upper part and the distance block 11, and the connection between the connecting block 12 and the cleaning machine frame can be conveniently performed through the installation gap. The distance block 11 is arranged between the connecting block 12 and the bearing seat 10, and is provided with a through hole for the bolts to pass through.

[0067] One of the bearings 9 is wrapped around the outside of the second sleeve 7, so that the bearing 9 can simultaneously support the transmission side shaft head 3 and the spline shaft 4 through the second sleeve 7. The connecting block 12 is arranged above the bearing seat 10 to fix the brush roller from above, so that the brush roller can be pressed downward for cleaning. Specifically, a transparent cover 13 is fixed to the side of the bearing seat 10 by bolts, and the transparent cover 13 covers the bearing 9 from the side.

[0068] This embodiment also provides a method for replacing a brushing roller, using the above easily replaceable brushing roller, and the replacement steps include:

[0069] S1: Disassemble the mounting seat at the operating side shaft head 1; S2: Pull out the transmission side shaft head 3 and the spline shaft 4 from the sleeve along the axial direction; S3: Connect the new brush roller to the spline shaft 4 through the flat key 8, insert the transmission side shaft head 3 connected with the spline shaft 4 into the sleeve, and align the splines of the spline shaft 4 and the connecting flange 5.

[0070] When the scrubbing roller is installed for the first time, the roller body is used as the basis. The transmission side shaft head is first connected to the spline shaft through a key fit, and then the connecting flange is sleeved onto the spline shaft through a spline fit to fix the position. Then, the first sleeve 6 and the second sleeve 7 are fixed with bolts in sequence to wrap the shaft head. Then, the bearing 9, the bearing seat 10, the transparent cover 13, the distance block 11, and the connecting block 12 are installed in sequence. Finally, the installed parts are fixed to the scrubbing machine frame through the connecting block. When replacing the scrubbing roller, only the connection on the operating side needs to be loosened to pull the scrubbing roller body out from the operating side to complete the disassembly.

[0071] In combination with the present embodiment, the specific replacement process of the brush roller is as follows: remove the bolts on the connecting block 12 on the operating side main shaft, remove the connecting block 12 and the distance block 11, disengage the connection between the bearing seat 10 and the cleaning frame, loosen the operating side pressure plate 14 installed on the brush frame, and then pull out the entire brush roller; the specific installation process is as follows: install the spline shaft 4 at the transmission side shaft head 3, insert the brush roller with the spline shaft 4 installed into the sleeve as a whole, engage the spline shaft 4 with the transmission flange, install the connecting block 12 and the distance block 11 at the operating side, and finally install the operating side pressure plate 14.

[0072] The above describes the preferred embodiments of the present invention. It should be understood that the present invention is not limited to the above-mentioned specific embodiments, and the devices and structures that are not described in detail should be understood to be implemented in a common manner in the art; any technician familiar with the art can use the above-disclosed methods and technical contents to make many possible changes and modifications to the technical solutions of the present invention without departing from the scope of the technical solutions of the present invention, or modify them into equivalent embodiments of equivalent changes, which does not affect the essential content of the present invention.
