Technical Field

[0001] This utility model relates to the field of steel plate roller brush technology, specifically a steel plate roller brush that facilitates brush strip replacement. Background Technology

[0002] During the production process of the steel plates manufactured by our company, rust removal is required on the surface of the steel plates. Currently, this is mostly done using roller brushes. Existing roller brushes typically consist of several brush strips evenly distributed around the outer circumference of the brush roller, with end caps at both ends to secure the brush strips. In practical use, when a brush strip needs to be replaced, the end caps must be removed, which is inconvenient. To solve this problem, this utility model provides a steel plate roller brush that facilitates brush strip replacement. Summary of the Invention

[0003] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a steel plate roller brush that facilitates brush strip replacement. When the connector is installed in the L-shaped connecting groove, the connector connects the eaves cover and the outer ring cover. When the connector is removed from the L-shaped connecting groove, the outer ring cover is rotated so that the second limiting groove corresponds to the brush strip installation position, thereby allowing the brush strip to be pulled out or inserted into the second limiting groove for installation. This allows for the removal and installation of partial brush strips without disassembling the end cap assembly, thus solving the technical problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a steel plate roller brush that facilitates brush bar replacement, comprising: a tubular brush roller, a plurality of brush bars, and an end cap assembly; a plurality of brush bar grooves are evenly distributed around the outer side of the tubular brush roller in a circumferential direction, and the sheet metal of the plurality of brush bars is fitted into the brush bar grooves; the end cap assembly includes an inner tube, an outer ring cap, and a connector; an eaves ring cap is provided on the outer side of the end of the inner tube, and the outer ring cap is rotatably mounted on the outer side of the eaves ring cap in a circumferential direction; the side ring of the outer ring cap is installed on the outer circumferential surface of the end of the tubular brush roller, limiting the end of the plurality of sheet metal; the eaves ring cap has a circumferential side opening A first limiting slot is provided, and a second limiting slot is provided on the outer end face of the outer ring cover. The second limiting slot is L-shaped and extends through the side ring and end ring of the outer ring cover. When the first limiting slot and the second limiting slot are aligned, an L-shaped connecting groove is formed for installing the connector. When the connector is installed in the L-shaped connecting groove, the connector connects the eaves cover and the outer ring cover. When the connector is removed from the L-shaped connecting groove, the outer ring cover is rotated so that the second limiting slot aligns with the brush strip installation position, thereby allowing the brush strip to be pulled out or inserted into the second limiting slot. The disassembly and installation of a portion of the brush strip can be achieved without disassembling the end cover assembly, which is convenient and practical.

[0005] Preferably, when the second limiting groove corresponds to the position of the brush strip groove, the brush strip groove is located inside the second limiting groove; ensuring that the brush strip can be easily pulled out or inserted into the second limiting groove for installation.

[0006] Preferably, the connector includes an L-shaped limiting plate, with inclined springs symmetrically installed on both sides of the horizontal plate of the L-shaped limiting plate. A horizontal lever is provided at the end of each inclined spring, and an arc-shaped protrusion is provided on the outer side of the horizontal lever. A strip-shaped limiting groove is symmetrically opened on both sides of the horizontal groove of the second limiting slot, and a groove is opened on the side of the strip-shaped limiting groove. When the connector is installed in the L-shaped connecting groove, the inclined spring is compressed and installed in the strip-shaped limiting groove, the arc-shaped protrusion is matched and installed in the groove, and the horizontal lever extends outward from the L-shaped connecting groove. In its natural state, the distance between the two horizontal levers is greater than the distance between the two strip-shaped limiting grooves. When the horizontal lever is installed in the strip-shaped limiting groove, the inclined spring is compressed and has elastic force. Under the action of the elastic force, the arc-shaped protrusion is matched and installed in the groove, achieving a stable connection between the inner tube and the outer ring cover.

[0007] Preferably, an annular groove is formed on the periphery of the eaves cover, and the inner side of the end ring is matched and installed in the annular groove; the inner tube is matched and installed on the inner side of the end of the tubular brush roller and connected by screws, and the connection is fastened by screws to ensure a stable connection between the end cover assembly and the inner tube.

[0008] Preferably, circular plates are symmetrically and coaxially fixedly installed on both sides inside the tubular brush roller, and a central shaft is coaxially fixedly installed on the two circular plates to ensure that the tubular brush roller can rotate stably.

[0009] The beneficial effects of this utility model are as follows: When the connector is installed in the L-shaped connecting groove, the connector connects the eaves cover and the outer ring cover. When the connector is removed from the L-shaped connecting groove, the outer ring cover is rotated so that the second limiting groove corresponds to the brush strip installation position, thereby allowing the brush strip to be pulled out or inserted into the second limiting groove for installation. The disassembly and installation of a portion of the brush strip can be achieved without disassembling the end cap assembly, which is convenient and practical.

[0010] When the horizontal lever is installed in the strip-shaped limiting groove, the inclined spring is squeezed and has elasticity. Under the action of elasticity, the arc protrusion is matched and installed in the groove, realizing a stable connection between the inner tube and the outer ring cover. When the inner tube and the outer ring cover need to rotate relative to each other, the horizontal lever is pinched with relative force, so that the two horizontal levers move relative to each other, and then the arc protrusion is disengaged from the groove. Then, the connector is pulled outward to separate the inner tube and the outer ring cover, which is convenient and practical. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0025] like Figures 1 to 11 As shown, this embodiment provides a steel plate roller brush for easy brush bar replacement, including: a tubular brush roller 1, several brush bars 2, and an end cap assembly; several brush bar grooves 11 are evenly distributed circumferentially on the outer side of the tubular brush roller 1, and the sheet metal 21 of several brush bars 2 is fitted into the brush bar grooves 11; in fact, please refer to Figure 5 As shown, the brush strip 2 includes a sheet metal 21, brush filaments, and iron wire. The brush filaments are evenly distributed on the strip-shaped sheet metal 21. At the center of the sheet metal 21, above the brush filaments, the iron wire is placed. The sheet metal is squeezed by the extrusion rollers on both sides, squeezing the brush filaments and iron wire between the two sides of the sheet metal 21. The squeezed sheet metal 21 has a narrower width at the tightening part and a wider width at the folding part. Therefore, the cross-section of the brush strip groove 11 is narrow on the outside and wide on the inside to fit the shape of the sheet metal 21.

[0026] Please see Figures 6 to 8 As shown, the end cap assembly includes an inner tube 31, an outer ring cap 32, and a connector. An eaves cap 311 is provided on the outer side of the end of the inner tube 31. The inner tube 31 and the eaves cap 311 are integrally formed. The outer ring cap 32 is rotatably mounted on the outer side of the eaves cap 311. The side rings 321 of the outer ring cap 32 are installed on the outer circumferential surface of the end of the tubular brush roller 1 to limit the ends of several pieces of iron sheet 21. When the iron sheet 21 is installed in the brush groove 11 and the side rings 321 are sleeved on the outer circumferential surface of the end of the tubular brush roller 1, the ends of the iron sheet 21 are tightly pressed against the inner surface of the side rings 321. At the same time, when the outer ring cap 32 is stably installed on the end of the tubular brush roller 1, the two ends of the iron sheet 21 are tightly pressed against the inner surfaces of the two end rings 322 to achieve the fastening and limiting of the iron sheet 21.

[0027] A first limiting groove 312 is provided on the circumferential side of the eaves cover 311, and a second limiting groove 323 is provided on the outer end face of the outer ring cover 32. The second limiting groove 323 is L-shaped and penetrates the side ring 321 and end ring 322 of the outer ring cover 32. When the first limiting groove 312 and the second limiting groove 323 are aligned, an L-shaped connecting groove for installing the connector is formed. When the connector is installed in the L-shaped connecting groove, the connector connects the eaves cover 311 and the outer ring cover 32. When the connector is removed from the L-shaped connecting groove, the outer ring cover 32 is rotated so that the second limiting groove 323 is aligned with the installation position of the brush strip 2, thereby allowing the brush strip 2 to be pulled out or inserted into the second limiting groove 323 for installation. The removal and installation of a portion of the brush strip 2 can be achieved without disassembling the end cover assembly, which is convenient and practical.

[0028] For further details, please refer to Figure 4 As shown, when the second limiting slot 323 corresponds to the brush strip groove 11, the brush strip groove 11 is located inside the second limiting slot 323, ensuring that the brush strip 2 can be easily pulled out or inserted into the second limiting slot 323 for installation.

[0029] For further details, please refer to Figures 6 to 11 As shown, the connector includes an L-shaped limiting plate 41. Inclined spring pieces 42 are symmetrically installed on both sides of the horizontal plate of the L-shaped limiting plate 41. A horizontal lever 421 is provided at the end of each inclined spring piece 42. An arc-shaped protrusion 422 is provided on the outer side of the horizontal lever 421. A strip-shaped limiting groove 324 is symmetrically opened on both sides of the horizontal groove section of the second limiting slot 323. A groove 325 is opened on the side of the strip-shaped limiting groove 324. When the connector is installed in the L-shaped connecting groove, the inclined spring piece 42 is compressed and installed in the strip-shaped limiting groove 324, the arc-shaped protrusion 422 is matched and installed in the groove 325, and the horizontal lever 421 extends outward from the L-shaped connecting groove. In its natural state... The distance between the two horizontal levers 421 is greater than the distance between the two strip-shaped limiting grooves 324. When the horizontal levers 421 are installed in the strip-shaped limiting grooves 324, the inclined spring 42 is squeezed and has elasticity. Under the action of elasticity, the arc protrusion 422 is matched and installed in the groove 325, realizing a stable connection between the inner tube 31 and the outer ring cover 32. When the inner tube 31 and the outer ring cover 32 need to rotate relative to each other, the horizontal levers 421 are pinched relative to each other, so that the two horizontal levers 421 move relative to each other, and then the arc protrusion 422 is disengaged from the groove 325. Then, the connector is pulled outward to separate the inner tube 31 and the outer ring cover 32, which is convenient and practical.

[0030] For further details, please refer to Figure 8 and Figure 9 As shown, an annular groove 313 is opened on the periphery of the eaves cover 311, and the inner side of the end ring 322 is matched and installed in the annular groove 313; the inner tube 31 is matched and installed on the inner side of the end of the tubular brush roller 1 and connected by screws.
