[0043] Reference Figure 1 As shown, the present invention provides a technical solution: a highly adaptable magnetic quick-release disc brush device, comprising:

[0044] The disc brush back plate 1 is a hollow structure. The upper end of the disc brush back plate 1 is fixedly connected to a rotating cylinder 7 for driving the disc brush back plate 1 to rotate. The inner wall of the rotating cylinder 7 is fitted with an output shaft 8 for controlling the overall rotation of the disc brush.

[0045] The disc brush 2 is located below the disc brush back plate 1, and several bristles 6 for cleaning are fixedly connected to the lower surface of the disc brush 2; and

[0046] An adjustable magnetic suction component 3 is located inside the disc brush disk 2; and a limiting component 4 is located on the outer wall of the rotating cylinder 7; the arc surface of the disc brush back plate 1 is provided with a sealing component 5 for sealing the bristles 6.

[0047] The following section will explain the specific settings and functions of the adjustable magnetic suction component 3, the limiting component 4, and the sealing component 5.

[0048] Reference Figures 2 to 6As shown in this embodiment: the adjustable magnetic suction component 3 includes two soft iron blocks 301, which are fixed to the inner wall of the brush back plate 1. The cross-section of the soft iron blocks 301 is half-circular. A circular hole 302 is provided on the side of each soft iron block 301 that is close to each other. A magnet 303 is disposed inside each of the two circular holes 302. A mounting hole 316 is provided inside the brush plate 2. A soft iron disc 317 is fixedly connected to the inner wall of the mounting hole 316. Rectangular holes 305 are provided on the upper and lower surfaces of the soft iron blocks 301. A copper strip 306 is attached to the inner wall of the rectangular hole 305. A rotating magnetic suction device 303 is provided on the outer wall of the brush back plate 1 to drive the magnet 303. 03 A rotating rod 304 is rotatably connected to a soft iron block 301. One end of the rotating rod 304 is fixedly connected to one side of a magnet 303. A gear 307 is fixedly connected to the arc surface of the rotating rod 304. A partition 308 is fixedly connected to the outer wall of the brush back plate 1. A bolt 309 is threaded through the side of the partition 308. One end of the bolt 309 is rotatably connected to an arc-shaped toothed block 310 for locking the gear 307. The arc-shaped toothed block 310 is engaged with the gear 307. A guide rod 311 for guiding and positioning the arc-shaped toothed block 310 is slidably passed through the side of the partition 308. One end of the guide rod 311 is fixedly connected to the arc-shaped toothed block 310. When installing the disc brush 2, first rotate bolt 309 to drive the arc-shaped toothed block 310, causing it to move away from the gear 307 under the guidance of guide rod 311. Once the arc-shaped toothed block 310 separates from the gear 307, it engages with the limiting positions of gear 307, rotating rod 304, and magnet 303. Then, move the disc brush 2 to align with the disc brush back plate 1. After the disc brush 2 aligns with the disc brush back plate 1, rotate rotating rod 304 to rotate magnet 303 to a horizontal position. When magnet 303 is horizontal, the magnetic attraction component generates a strong magnet, attracting the soft iron disc 317 inside the disc brush 2, tightly adhering to the disc brush 2. Finally, rotate bolt 309 to drive the arc-shaped toothed block 310 to engage the gear... When 307 is engaged, the installation of the disc brush 2 is complete. When the disc brush 2 needs to be disassembled, first rotate the bolt 309 to drive the arc-shaped toothed block 310 to separate from the toothed ring 401, then rotate the rotating rod 304 to drive the magnet 303 to rotate in the opposite direction, so that the magnet 303 rotates to the vertical position. When the magnet 303 is in the vertical direction, the magnetism of the magnetic attraction component disappears, and the disc brush 2 detaches from the surface of the disc brush back plate 1. By setting the adjustable magnetic attraction component 3, the disc brush 2 can be quickly replaced after wear, saving time and effort and improving cleaning efficiency. Since screws are not used for fastening, there is no need to open the fixing hole 407 in the disc brush 2. The brush material model can be laid out according to the chip removal needs of the fluid on the disc brush surface without avoiding the fixing hole 407, which improves the adaptability of the disc brush to the brush material.

[0049] The adjustable magnetic attraction assembly 3 also includes an arc-shaped rail 315 for limiting the rotation angle of the magnet 303. The arc-shaped rail 315 is in the shape of a quarter circle. A slide rod 314 is slidably connected to the inner wall of the arc-shaped rail 315. A handle 313 is fixedly connected to the end of the rotating rod 304 away from the magnet 303, allowing a person to rotate the rotating rod 304. The side of the handle 313 near the rotating rod 304 is fixedly connected to the end of the slide rod 314 away from the arc-shaped rail 315. A person can rotate the rotating rod 304 and the magnet 303 with the help of the handle 313. When the handle 313 is rotated, the slide rod 314 fixed on the handle 313 will slide along the inner wall of the arc-shaped rail 315. Since the arc-shaped rail 315 is in the shape of a quarter circle, the rotation angle of the magnet 303 can be limited, so that it can only rotate 90 degrees.

[0050] The arc surface of the rotating rod 304 is fitted with a sealing ring 312 to improve the sealing performance at the connection between the rotating rod 304 and the disc brush back plate 1. One side of the sealing ring 312 is fixedly connected to the outer wall of the disc brush back plate 1. The sealing ring 312 can seal the tiny gaps between the rotating rod 304 and the disc brush back plate 1, thereby improving the sealing performance at the connection between the rotating rod 304 and the disc brush back plate 1.

[0051] A positioning tenon 318 is fixedly connected to the outer edge of the brush back plate 1 near the brush disc 2. The outer edge of the brush disc 2 near the brush back plate 1 is chamfered, and the beveled surface of the chamfered surface of the brush disc 2 fits into the inner wall of the positioning tenon 318. When aligning the brush back plate 1 and the brush disc 2, the beveled surface of the brush disc 2 needs to fit into the inner wall of the positioning tenon 318, which serves as an auxiliary positioning function, allowing the brush back plate 1 and the brush disc 2 to be aligned centered.

[0052] The lower surface of the brush back plate 1 is fixedly connected with several protrusions 319, and the upper surface of the brush disc 2 is provided with several grooves 320, the grooves 320 corresponding to the protrusions 319. When connecting the brush back plate 1 and the brush disc 2, the protrusions 319 need to be inserted into the grooves 320. At this time, they can withstand the shearing force of the brush during rotation and prevent relative rotational displacement between the brush back plate 1 and the brush disc 2.

[0053] Reference Figure 7 and Figure 8As shown, in this embodiment: the limiting component 4 includes a gear ring 401 and several sliding plates 403. The sliding plates 403 are fixed to the outer wall of the rotating cylinder 7. An annular hole 402 is provided on the inner wall of the gear ring 401. The sliding plates 403 are slidably connected to the inner wall of the annular hole 402. Several fixing blocks 406 are slidably passed through the outer wall of the rotating cylinder 7. Several arc-shaped holes 404 are provided on the surface of the gear ring 401. Several connecting rods 405 for driving the fixing blocks 406 to move are slidably connected to the inner wall of the arc-shaped holes 404. The upper end of the connecting rod 405 is fixedly connected to the lower surface of the fixing block 406. The arc surface of the output shaft 8 Several fixing holes 407 are provided, and the size of the fixing holes 407 is adapted to the fixing block 406. Two support plates 408 are fixedly connected to the upper surface of the brush back plate 1. A lead screw 409 is rotatably connected to one side of the two support plates 408 that are close to each other. A turntable 410 is rotatably inserted on one side of one of the support plates 408 to facilitate the rotation of the lead screw 409 by personnel. The turntable 410 is fixedly connected to the lead screw 409. An ear plate 411 is threadedly connected to the arc surface of the lead screw 409. A rack 414 for driving the gear ring 401 to rotate is fixedly connected to one side of the ear plate 411. The rack 414 meshes with the gear ring 401. When the disc brush back plate 1 needs to be disassembled from the output shaft 8 of the cleaning machine after a period of use, first rotate the turntable 410 to drive the lead screw 409 to rotate. The lead screw 409 drives the ear plate 411, which in turn drives the rack 414 to move. The rack 414 drives the gear ring 401 to rotate. When the gear ring 401 rotates, the sliding plate 403 fixed on the arc surface of the disc brush back plate 1 slides along the inner wall of the annular hole 402 on the gear ring 401, thus supporting the rotation of the gear ring 401. At the same time, the gear ring 401 drives the connecting rod 405 through the arc hole 404, causing the connecting rod 405 to drive the fixing plate to separate from the fixing hole 407. After separation, move the rotating cylinder 7 to separate from the output shaft 8, thus completing the disassembly of the disc brush back plate 1. At this time, personnel can then perform maintenance on the disc brush back plate 1. After maintenance is completed... After completion, the disc brush back plate 1 is moved to drive the rotating cylinder 7, which is then placed on the arc surface of the output shaft 8. When the fixing block 406 is aligned with the fixing hole 407, the turntable 410 is rotated to drive the lead screw 409 to rotate in the opposite direction. The lead screw 409 drives the ear plate 411 to move in the opposite direction, which in turn drives the rack 414 to move in the opposite direction. The rack 414 drives the gear ring 401 to rotate in the opposite direction, and the gear ring 401 drives the connecting rod 405 through the arc hole 404. This causes the connecting rod 405 to drive the fixing block 406 through the rotating cylinder 7 and into the fixing hole 407. Once the insertion is stable, the installation of the disc brush back plate 1 is complete. By setting the limiting component 4, personnel can easily disassemble and assemble the disc brush back plate 1, which facilitates the maintenance of the parts on the disc brush back plate 1 and improves the overall service life of the disc brush back plate 1.

[0054] A pressure rod 412 for locking the lead screw 409 is threaded through the side of the ear plate 411 away from the rack 414. One end of the pressure rod 412 abuts against the arc surface of the lead screw 409. When the rack 414 is adjusted to the appropriate position, rotating the pressure rod 412 to abut against the lead screw 409 can lock the lead screw 409, thereby preventing the rack 414 from shaking due to accidental movement of the lead screw 409.

[0055] A positioning rod 413 for guiding and positioning the ear plate 411 is slidably provided on the side of the ear plate 411. The positioning rod 413 is fixedly connected to the upper surface of the disc brush back plate 1. When the lead screw 409 drives the ear plate 411 to move, the positioning rod 413 can guide and position the ear plate 411, thereby improving the ability to prevent rotational deviation during the movement of the ear plate 411.

[0056] Reference Figure 9 and Figure 10 As shown in this embodiment: the sealing assembly 5 includes a fixing seat 51, which is fixedly connected to the arc surface of the disc brush back plate 1. A rotating shaft 52 is rotatably provided through the inner wall of the fixing seat 51. A connecting plate 53 is fixedly connected to the arc surface of the rotating shaft 52. A sealing cover 54 for sealing the brush bristles 6 is fixedly connected to one side of the connecting plate 53. A sealing strip 55 for improving the sealing between the sealing cover 54 and the disc brush 2 is fixedly connected to one side of the sealing cover 54. The sealing strip 55 is in the shape of a ring. When the bristles 6 need to be sealed after use, first rotate the sealing cover 54 to make it rotate closer to the bristles 6. During the rotation of the sealing cover 54, it will drive the connecting plate 53, and the connecting plate 53 will drive the rotating shaft 52, so that the rotating shaft 52 rotates along the inner wall of the fixed base 51. When the sealing cover 54 drives the sealing strip 55 to abut against the lower surface of the disc brush 2, the bristles 6 can be sealed. When it is necessary to open the sealing cover 54, the personnel only need to drive the sealing cover 54 to rotate in the opposite direction. By setting the sealing component 5, after the disc brush has finished cleaning, the sealing cover 54 can be adjusted to seal and protect the bristles 6, thereby preventing dust and dirt from adhering to the bristles 6 when the disc brush is not in use, and effectively ensuring the cleanliness of the cleaning process.

[0057] One end of the rotating shaft 52 is fixedly connected to a disc 56 for driving the rotating shaft 52 to rotate. A connecting rod 57 is rotatably connected to the centrifugal position of the disc 56 away from the rotating shaft 52. A welding plate 58, which provides support, is fixedly connected to the arc surface of the disc brush back plate 1. An electric actuator 59 is fixedly connected to one side of the welding plate 58, and the output end of the electric actuator 59 is rotatably connected to one end of the connecting rod 57. When it is necessary to control the automatic rotation of the sealing cover 54, the electric actuator 59 is first activated to drive the connecting rod 57 to rotate. The connecting rod 57 drives the turntable 410 to rotate, and the turntable 410 drives the rotating shaft 52 to rotate, thereby driving the sealing cover 54 to rotate automatically. By setting the above structure, the sealing cover 54 can be opened and closed automatically, thus enabling the sealing brush bristles 6 to operate automatically.

[0058] Working principle: When the disc brush 2 needs to be installed, first rotate the bolt 309 to drive the arc-shaped toothed block 310, so that the arc-shaped toothed block 310 moves away from the gear 307 under the guidance and positioning of the guide rod 311. After the arc-shaped toothed block 310 separates from the gear 307, it can contact the limiting position of the gear 307, the rotating rod 304 and the magnet 303. Then move the disc brush 2 to align with the disc brush back plate 1. After the disc brush 2 is aligned with the disc brush back plate 1, rotate the rotating rod 304 to drive the magnet 303 to rotate, so that the magnet 303 rotates to... When the magnet 303 is in a horizontal position, the magnetic attraction component generates a strong magnet, which attracts the soft iron disc 317 inside the brush disc 2, tightly adhering to the brush disc 2. Finally, rotating the bolt 309 drives the arc-shaped toothed block 310 to lock the gear 307, thus completing the installation of the brush disc 2. When it is necessary to disassemble the brush disc 2, first rotate the bolt 309 to drive the arc-shaped toothed block 310 to separate from the gear ring 401, then rotate the rotating rod 304 to drive the magnet 303 to rotate in the opposite direction, so that the magnet 303 rotates to the vertical position. When the direction is perpendicular, the magnetism of the magnetic component disappears, and the brush disc 2 detaches from the surface of the brush back plate 1. A person can then rotate the rotating rod 304 and the magnet 303 using the handle 313. When the handle 313 is rotated, the sliding rod 314 fixed to the handle 313 slides along the inner wall of the arc-shaped rail 315. Since the arc-shaped rail 315 is a quarter-circle arc, the rotation angle of the magnet 303 can be limited to only ninety degrees. Furthermore, the sealing ring 312 can close the tiny gap between the rotating rod 304 and the brush back plate 1. The blockage improves the sealing performance at the connection between the rotating rod 304 and the disc brush back plate 1. Finally, when connecting the disc brush back plate 1 and the disc brush plate 2, the beveled surface of the disc brush plate 2 needs to be fitted with the inner wall of the positioning tenon 318, which plays an auxiliary positioning role, so that the disc brush back plate 1 and the disc brush plate 2 can be centered. When connecting the disc brush back plate 1 and the disc brush plate 2, the boss 319 needs to be inserted into the groove 320. At this time, it can withstand the shearing force of the disc brush in the rotating state and prevent the disc brush back plate 1 and the disc brush plate 2 from rotating and shifting relative to each other.

[0059] When the disc brush back plate 1 needs to be disassembled from the output shaft 8 of the cleaning machine for maintenance after a period of use, first rotate the turntable 410 to drive the lead screw 409 to rotate. The lead screw 409 drives the ear plate 411, which in turn drives the rack 414 to move. The rack 414 drives the gear ring 401 to rotate. When the gear ring 401 rotates, the sliding plate 403 fixed on the arc surface of the disc brush back plate 1 slides along the inner wall of the annular hole 402 on the gear ring 401, thereby supporting the rotation of the gear ring 401. At the same time, the gear ring 401 drives the connecting rod 405 with the help of the arc hole 404, causing the connecting rod 405 to drive the fixing plate to separate from the fixing hole 407. After separation, move the rotating cylinder 7 to separate it from the output shaft 8, thus completing the disassembly of the disc brush back plate 1. At this time, personnel can then perform maintenance on the disc brush back plate 1. After maintenance is completed, move the disc brush back plate 1 to drive the rotating cylinder 7, and place the rotating cylinder 7 onto the arc surface of the output shaft 8. After the fixing block 406 is aligned with the fixing hole 407, the turntable 410 is rotated to drive the lead screw 409 to rotate in the opposite direction. The lead screw 409 drives the ear plate 411 to move in the opposite direction. The ear plate 411 drives the rack 414 to move in the opposite direction. The rack 414 drives the gear ring 401 to rotate in the opposite direction. The gear ring 401 drives the connecting rod 405 through the arc hole 404, so that the connecting rod 405 drives the fixing block 406 through the rotating cylinder 7 and inserts it into the fixing hole 407. After the insertion is stable, the installation of the disc brush back plate 1 can be completed. When the lead screw 409 drives the ear plate 411 to move, the positioning rod 413 can guide and position the ear plate 411, thereby preventing the ear plate 411 from rotating and deviating during the movement process. In addition, when the rack 414 is adjusted to the appropriate position, the pressure rod 412 is rotated to abut against the lead screw 409, which can lock the lead screw 409, thereby preventing the rack 414 from shaking due to accidental movement of the lead screw 409.

[0060] When the bristles 6 need to be sealed after use, first rotate the sealing cover 54 to make it rotate closer to the line of the bristles 6. During the rotation of the sealing cover 54, it will drive the connecting plate 53, and the connecting plate 53 will drive the rotating shaft 52, so that the rotating shaft 52 rotates along the inner wall of the fixed base 51. When the sealing cover 54 drives the sealing strip 55 to abut against the lower surface of the disc brush 2, the sealing of the bristles 6 can be completed. When it is necessary to open the sealing cover 54, the operator only needs to drive the sealing cover 54 to rotate in the opposite direction. When it is necessary to control the automatic rotation of the sealing cover 54, first start the electric actuator 59 to drive the connecting rod 57 to operate. The connecting rod 57 drives the turntable 410 to rotate, and the turntable 410 drives the rotating shaft 52 to rotate, thereby driving the sealing cover 54 to rotate automatically. By setting the above structure, the sealing cover 54 can be opened and closed automatically, so that the sealing of the bristles 6 can be carried out automatically.
