DETAILED DESCRIPTION

[0023] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0024] The present invention has multiple embodiments, and the specific implementation methods are as follows: Example 1: Figure 1-10As shown, the present invention provides a brush roller structure for rotating and replacing brush strips, comprising a roller shaft 1 and a base tube 2 installed coaxially with the roller shaft 1; a plurality of arc-shaped brush plates 3 for arranging brush strips 32 are arranged circumferentially on the outer wall of the base tube 2; a strip-shaped plug-in portion 31 is provided on the inner wall of the arc-shaped brush plate 3; a strip-shaped plug-in groove 21 matching the strip-shaped plug-in portion 31 is provided through the outer side of the base tube 2; the strip-shaped plug-in portion 31 is inserted into the strip-shaped plug-in groove 21 to keep the arc-shaped brush plate 3 fixed in the axial direction; two end plates 4 respectively located at the two ends of the base tube 2 are sleeved on the roller shaft 1, and the end plates 4 can play a certain shielding and sealing role; the inner end face of the end plate 4 is provided with an annular seat extending inwards 41, in this embodiment, the outer diameter of the annular seat 41 is smaller than the outer diameter of the end plate 4; a connecting assembly is provided between the two ends of the strip plug-in portion 31 and the corresponding annular seat 41, and the connecting assembly includes a fixed connecting piece arranged on the strip plug-in portion 31 and located in the base pipe 2, and a movable connecting piece arranged on the annular seat 41 and corresponding to the fixed connecting piece, which are two axially opposite movable connecting pieces that can be synchronously disengaged or matched with the corresponding fixed connecting piece. Between the two annular seats 41, a linkage structure is connected between each two axially opposite movable connecting pieces. The roller shaft 1 is sleeved with a rotating drive tube 71 that can rotate along the axis of the roller shaft 1, and the rotating drive tube 71 is provided with a driving part for acting on the linkage structure; The brush roller structure has a working mode and a disassembly mode. When the brush roller structure is in the working mode, the movable connecting part cooperates with the fixed connecting part to make the corresponding arc-shaped brush plate 3 close to the base tube 2. At this time, the brush roller structure can grind the steel plate normally; when the brush roller structure switches to the disassembly mode, the rotating drive tube 71 rotates and makes the driving part act on the corresponding linkage structure to link the two axially opposite movable connecting parts to move synchronously and separate from the corresponding fixed connecting parts. At this time, you only need to pull the strip plug-in part 31 out of the strip plug-in groove 21 to make the corresponding arc-shaped brush plate 3 can be removed from the base tube 2.

[0025] Further, in this embodiment, the connection assembly is a hook-type assembly, specifically, the fixed connection member is a fixed hook 311 arranged on the strip-shaped plug-in portion 31, and the movable connection member is a plurality of movable hooks 51 uniformly distributed along the circumferential direction on the annular seat 41; the annular seat 41 is provided with a plurality of rotating connection seats 52 uniformly distributed along the circumferential direction, and the corresponding movable hooks 51 are rotatably mounted on the rotating connection seats 52; the rotating connection seats 52 provide corresponding mounting carriers for the movable hooks 51; the movable hooks 51 can swing on the annular seat 41 and disengage from the fixed hooks 311, so that the corresponding arc-shaped brush plate 3 is separated from the base pipe 2; When the brush roller structure is in working mode, the movable hook 51 and the fixed hook 311 are interlocked so that the corresponding arc-shaped brush plate 3 is tightly attached to the base tube 2; when the brush roller structure is switched to disassembly mode, the rotating drive tube 71 is rotated and the driving part acts on the corresponding linkage structure to link the two axially opposite movable hooks 51 to swing synchronously and separate from the corresponding fixed hooks 311, so that the corresponding arc-shaped brush plate 3 can be removed from the base tube 2.

[0026] Furthermore, the linkage structure needs to simultaneously link the movable hook 51 to swing synchronously so as to achieve cooperation or separation with the fixed hook 311. Therefore, in the present embodiment, the linkage structure is an elastic V-shaped rod 6 connected between two axially opposite movable hooks 51, and the driving part is a top block 72 arranged on the outer wall of the rotating driving tube 71; the rotating driving tube 71 rotates to cause the top block 72 to press and cause the corresponding elastic V-shaped rod 6 to deform, so as to link the two axially opposite movable hooks 51 to swing synchronously; when acted upon by the top block 72, the elastic V-shaped rod 6 can convert its own elastic force into a linkage force to act on the movable hook 52 to act on the movable hook 51, and when the top block 72 is separated from the elastic V-shaped rod 6, the elastic V-shaped rod 6 can be quickly reset to make the movable hook 51 cooperate with the fixed hook 311 on the new arc brush plate 3 to limit the arc brush plate 3 from detaching.

[0027] Furthermore, the elastic V-shaped rod 6 includes support arms respectively connected to two axially opposite movable hooks 51. In order to enable the two axially opposite movable hooks 51 to synchronously disengage from the fixed hook 311, the two movable hooks 51 should be subjected to the same linkage force so as to produce the same swing amplitude. Therefore, in this embodiment, the top block 72 corresponds to the junction of the two support arms; the rotary drive tube 71 rotates to cause the top block 72 to press the junction of the two support arms on the corresponding elastic V-shaped rod 6 and cause the elastic V-shaped rod 6 to deform so as to link the two axially opposite movable hooks 51 to swing synchronously; the top block 72 can cause the two support arms to produce the same amplitude of deformation, so that each two axially opposite movable hooks 52 can stably disengage from the corresponding fixed hook 311.

[0028] Furthermore, in order to enable the movable hook 51 to be quickly reset, the brush roller structure also includes an elastic member, which acts on the movable hook 52. When the driving part acts on the corresponding linkage structure, the movable hook 51 swings and causes the elastic member to deform. When the driving part is separated from the linkage structure, the elastic member releases the elastic force and causes the outer hook 51 to reset. The elastic member can provide a reset elastic force for the movable hook 51, so that when the brush roller structure is in the working mode, the movable hook 51 can form a snap-fit ​​with the fixed hook 311. Specifically, the movable hook 51 is rotatably connected to the rotating connecting seat 52 through a rotating shaft, and the elastic member is a torsion spring 53 that is sleeved on the rotating shaft and acts on the movable hook 51. The torsion spring 53 can provide sufficient reset elastic force for the movable hook 51, while occupying a small space, which is convenient for layout.

[0029] Further, if Figure 7-9 As shown, in order to facilitate the control of the rotating drive tube 71, a plurality of first limit blocks 712 are evenly distributed along the circumferential direction on the inner wall of the rotating drive tube 71; a plurality of first limit grooves 12 corresponding to the first limit blocks 712 are evenly distributed along the circumferential direction on the outer wall of the roller shaft 1; the first limit grooves 12 extend axially, and the first limit blocks 712 are slidably connected in the first limit grooves 12; an annular groove 13 connected to the plurality of first limit grooves 12 is also provided on the outer wall of the roller shaft 1; when the brush roller structure is in the working mode, the plurality of first limit blocks 712 are stuck in the corresponding first limit grooves 12 to limit the rotation of the rotating drive tube 71; when the brush roller structure is switched to the disassembly mode, the external force pulls the rotating drive tube 71 to slide on the roller shaft 1, so that the plurality of first limit blocks 712 The rotating drive tube 71 slides from the first limiting groove 12 to the annular groove 13, and at this time, the rotating drive tube 71 can rotate axially; specifically, the states of the rotating drive tube 71 are different in the working mode and the disassembly mode. The first limiting block 712 and the first limiting groove 12 can limit the rotation of the rotating drive tube 71 when they cooperate to prevent the movable hook 51 from accidentally disengaging from the fixed hook 311 in the working mode. When the first limiting block 712 and the annular groove 13 cooperate, it is equivalent to releasing the circumferential rotation restriction of the rotating drive tube 71, so that the movable hook 51 and the fixed hook 311 can be freely disengaged in the disassembly mode. The design is simple and clever, and can realize the rotation control of the rotating drive tube 71, thereby allowing the brush roller structure to freely switch between the working mode and the disassembly mode.

[0030] Furthermore, the end plate 4 is relatively fixed with the base tube 2 in the circumferential direction, and the end plate 4 is usually connected to the two ends of the base tube 2 by screws; a plurality of second limit blocks 711 are evenly distributed along the circumferential direction on the outer wall of the rotating drive tube 71; a plurality of second limit grooves 411 are evenly distributed in an annular manner on the inner side of the annular seat 41; the second limit blocks 711 are matched and installed in the second limit grooves 411; when the brush roller structure is in the working mode, a plurality of second limit blocks 711 are stuck in the corresponding second limit grooves 411 to limit the rotation of the rotating drive tube 71; when the brush roller structure is switched to the disassembly mode, an external force pulls the rotating drive tube 71 to slide on the roller shaft 1, so that the plurality of second limit blocks 711 are disengaged from the second limit grooves 411. The second limiting groove 411, at this time, the rotating drive tube 71 can rotate axially; specifically, in the working mode and the disassembly mode, the second limiting block 711 and the second limiting groove 411 can limit the rotation of the rotating drive tube 71 when they cooperate to prevent the movable hook 51 and the fixed hook 311 from accidentally disengaging in the working mode. When the second limiting block 711 disengages from the second limiting groove 411, it is equivalent to releasing the circumferential rotation restriction on the rotating drive tube 71, so that the movable hook 51 and the fixed hook 311 can be freely disengaged in the disassembly mode. This design is simple and clever, and can achieve another level of control over the rotating drive tube 71, so that the brush roller structure can be freely switched between the working mode and the disassembly mode.

[0031] Furthermore, in order to facilitate workers to rotate the rotating drive tube 71 when the arc-shaped brush plate 3 needs to be replaced, one end of the rotating drive tube 71 passes outward from the end plate 4 and forms an exposed section, and a plurality of toggle grooves 713 are evenly distributed along the circumference of the exposed section; the toggle grooves 713 can facilitate workers to rotate the rotating drive tube 71 manually or using a wrench. When the rotating drive tube 71 is manually rotated, the toggle grooves 713 can increase the friction; when using a wrench, the toggle grooves 713 can cooperate with the wrench to quickly rotate the rotating drive tube 71.

[0032] Furthermore, the rotating drive tube 71 is sleeved on the roller shaft 1 in this way: the roller shaft 1 has a large diameter section and a small diameter section 11 which are connected to each other, and a step surface is formed at the connection position of the large diameter section and the small diameter section 11, and the rotating drive tube 71 is sleeved on the small diameter section 11; in order to prevent the rotating drive tube 71 from moving in the axial direction in the working mode, a magnet A714 is embedded in the end surface facing the step surface; a magnet B111 attracted to the magnet A714 is embedded in the step surface; through the mutual attraction between magnet A and magnet B, the rotating drive tube 71 can be stably sleeved on the small diameter section when no adjustment is required.

[0033] Furthermore, the top block 72 is located between two adjacent elastic V-shaped rods 6. In order to more smoothly press the elastic V-shaped rods 6, wedge surfaces 721 are provided on both sides of the top block 72 facing the two elastic V-shaped rods 6; the wedge surfaces 721 make it easier for the top block 72 to rotate to the bottom of the junction of the two arms, which is convenient and labor-saving.

[0034] Embodiment 2: This embodiment is different from the above embodiment in that the linkage structure is different, such as Fig.11 As shown, the linkage structure in this embodiment is an elastic telescopic component arranged between two axially opposite movable hooks 51, and the elastic telescopic component includes two elastic telescopic rods 8 respectively hinged to the two axially opposite movable hooks 51, and the elastic telescopic rods are provided with linkage inclined surfaces 81 corresponding to the positions of the top blocks 72. The rotating driving tube 71 rotates to make the top blocks 72 press the linkage inclined surfaces 81 and promote the elastic telescopic rods 8 to elastically expand and contract, so as to link the two axially opposite movable hooks 51 to swing synchronously; specifically, a plurality of supports 4 are evenly distributed along the circumferential direction on the annular seat 4. 2. A guide hole is provided on the support 42, and the corresponding elastic telescopic rod 8 passes through the guide hole. The elastic telescopic rod 8 has an annular protrusion 82. A compression spring 9 is provided between the annular protrusion 82 and the support 42 to provide a telescopic elastic force for the elastic telescopic rod 8. When the top block 72 acts on the linkage inclined surface 81, the elastic telescopic rod 8 can rely on its own telescopic process to form a linkage force on the movable hook 52. When the top block 72 is separated from the linkage inclined surface 81, the elastic telescopic rod 8 can rely on the elastic force stored after the compression spring 9 is deformed to quickly reset; so as to achieve the same linkage effect as in the above embodiment.

[0035] Embodiment 3: This embodiment is different from the above embodiments in that the connecting component is a plug-in component, such as Fig.12 As shown, the fixed connection piece is a clamping seat 33 arranged on the strip-shaped plug-in portion 31, and a clamping hole 34 is provided on the clamping seat 33. The movable connection piece is a plurality of movable plug-in pieces 54 uniformly distributed along the circumferential direction on the annular seat 41; a clamping column 55 for clamping with the clamping hole 34 is provided on the movable plug-in piece 54; a plurality of rotating connection seats 52 are also uniformly distributed along the circumferential direction on the annular seat 4, and the movable plug-in piece 54 is rotatably installed on the corresponding rotating connection seat 52, so that the movable plug-in piece 54 can swing on the annular seat 41 and make the clamping column 55 escape from the clamping hole 34, so that the corresponding arc-shaped brush plate 3 is separated from the base pipe 2; When the brush roller structure is in working mode, the clamping column 55 is inserted into the clamping hole 34 so that the corresponding arc-shaped brush plate 3 is tightly attached to the base tube 2; when the brush roller structure is switched to disassembly mode, the rotating driving tube 71 rotates and causes the driving part to act on the corresponding linkage structure to link the two axially opposite movable connectors 54 to swing synchronously and cause the corresponding clamping column 55 to escape from the clamping hole 34, so that the corresponding arc-shaped brush plate 3 can be removed from the base tube 2, thereby achieving the same coordination effect as in the above-mentioned embodiment.
