[0045] In the following, the exemplary solutions of the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings of the specific embodiments of the present utility model. Unless otherwise defined, the technical terms or scientific terms used in the present utility model shall have the ordinary meaning understood by those of ordinary skill in the art.

[0046] As Figure 1 and Figure 2 shown, for the brush roll cleaning device of the working roll of the aluminum plate rolling mill in this embodiment, the working roll 1 is rotatably arranged on the hot rolling frame 2. The brush roll device includes a support member 5, a brush roll 6, a driving part 3 and a pushing member 7. The support member 5 is rotatably installed on the hot rolling frame 2. The brush rolls 6 are symmetrically arranged on both sides of the working roll 1, and both ends of the brush roll 6 are rotatably arranged on the support member 5. The driving part 3 is fixedly arranged on the hot rolling frame 2 and is connected and fixed to one end of the brush roll 6 through a connecting member 4 to drive the brush roll 6 to axially move and radially rotate. The pushing member 7 is fixedly installed on the hot rolling frame 2 and is correspondingly arranged with the support member 5 for pushing the support member 5 to rotate so as to drive the brush roll 6 to move towards the working roll 1.

[0047] Furthermore, the surface of the brush roll 6 is wrapped with flexible bristles 610, which can effectively clean the impurities on the surface of the working roll 1 and avoid leaving scratches on the surface of the working roll 1 at the same time.

[0048] As Figure 6 shown, the support member 5 includes an L-shaped support frame 513. The support frame 513 includes a horizontal part and a vertical part, and the vertical part is a bearing seat 511.

[0049] A through hole is opened at the center of the horizontal part of the support frame 513, and the horizontal part is rotatably sleeved outside the support shaft 512, and the support shaft 512 is welded and fixed on the hot rolling frame 2.

[0050] A bearing 510 is installed inside the bearing seat 511, and the brush roll 6 is arranged inside the bearing seat 512 through the bearing 510.

[0051] Furthermore, as Figure 7 shown, a bushing 514 and a sliding sleeve 516 are sequentially sleeved between the brush roll 6 and the bearing 510. A first groove 517 is opened on the outer wall of the bushing 514, and a second groove 518 corresponding to the first groove 517 is opened on the inner wall of the sliding sleeve 516. By arranging a second key 515 between the first groove 517 and the second groove 518, the engagement between the bushing 514 and the sliding sleeve 516 is realized.

[0052] As Figure 3 shown, the driving part 3 includes a moving cylinder 310 fixedly installed on the hot rolling frame 2 and a universal shaft 320 connected to the moving cylinder 310 through a pin shaft. The universal shaft 320 is connected to the brush roll 6 through a connecting member 4.

[0053] During long-term use, the reciprocating oil cylinder 310 and the connecting member 4 may be misaligned or displaced. The universal shaft 320 can automatically adapt to this misalignment or displacement, ensuring smooth power transmission between the reciprocating oil cylinder 310 and the connecting member 4.

[0054] As Figure 5 shown, the connecting member 4 includes a first coupling shaft 410 and a second coupling shaft 413 that are butt-jointed. The left end of the first coupling shaft 410 is connected to the universal shaft 320 by bolts. The first coupling shaft 410 and the second coupling shaft 413 are tightly connected by two half-rings 412 sleeved on their circumferences. The two half-rings 412 are connected and fixed by bolts, ensuring that the first coupling shaft 410 and the second coupling shaft 413 do not come apart while improving the convenience of disassembling and replacing the connecting member 4.

[0055] A counterbore is provided at the right end of the first coupling shaft 410, and a through hole is provided at the center of the second coupling shaft 413. The brush roll 6 passes through the second coupling shaft 413 and extends into the counterbore of the first coupling shaft 410, and the brush roll 6 is locked in the connecting member 4 by a round nut 411.

[0056] Further, an annular protrusion 414 is provided in the through hole of the second coupling shaft 413. After the brush roll 6 passes through the annular protrusion 414 of the second coupling shaft 413, the round nut 411 is installed and tightened to achieve the connection and fixation between the brush roll 6 and the second coupling shaft 413, ensuring that the reciprocating oil cylinder 310 can drive the brush roll 6 to axially reciprocate through the connecting member 4.

[0057] Further, a first key 620 is provided at the end of the brush roll 6 for engaging between the second coupling shaft 413 and the brush roll 6, ensuring that the reciprocating oil cylinder 310 can drive the brush roll 6 to rotate radially through the connecting member 4.

[0058] A stopper 520 is provided on the hot rolling mill stand 2 for restricting the distance of the brush roll 6 moving radially along the work roll 1.

[0059] As Figure 4 and Figure 8 shown, the stopper 520 includes a stopper body 521 and a stopper bracket 524 installed on the hot rolling mill stand 2. The stopper body 521 is hingedly arranged in the stopper bracket 524.

[0060] A limiting rod 523 is slidably inserted through the inside of the stopper body 521. A limiting block 522 inserted and fixed in the stopper body 521 is provided on the outer side of the limiting rod 523 for restricting the sliding of the limiting rod 523. The limiting rod 523 is hingedly arranged on a hinge seat 525, and the hinge seat 525 is welded and fixed on the horizontal part of the support frame 513.

[0061] Further, a limiting protrusion 526 is provided on the limiting rod 523. During the sliding process of the limiting rod 523 inside the limiting body 521, when the limiting block 522 contacts the limiting protrusion 526, the sliding of the limiting rod 523 stops.

[0062] The pushing member 7 adopts a hydraulic cylinder 710, and a push rod 720 is arranged inside the hydraulic cylinder 710. The push rod 720 pushes the support frame 513 to drive the brush roller 6 to move towards the working roller 1. At the same time, the support frame 513 drives the limiting rod 523 to slide through the hinge seat 525. When the bristles 610 on the brush roller 6 contact the surface of the working roller 1, the limiting rod 523 is restricted by the limiter 520 and stops sliding, thereby causing the brush roller 6 to stop moving towards the working roller 1, so as to realize the limiting of the brush roller 6 by the limiter 520.

[0063] Further, a plurality of groups of card slots 527 for inserting and fixing the limiting blocks 522 are opened on both sides of the limiting body 521. In actual production, according to the on-site needs, the limiting blocks 522 can be inserted into the card slots 527 at different positions, so as to adjust the sliding distance of the limiting rod 523.

[0064] The limiter 520 limits the stroke of the brush roller moving radially along the working roller 6, avoiding the push rod 710 over-pushing the support member 5 so that the brush roller 6 squeezes the working roller 1 and causing damage to the working roller 1.

[0065] Further, for working rollers 1 with different diameters, the limiting blocks 522 can be inserted into the card slots 527 at different positions to adjust the sliding stroke of the limiting rod 523, and then control the distance that the brush roller 6 moves radially along the working roller 1, ensuring that the bristles 610 contact the working roller 1 without extrusion.

[0066] The working principle of this application is:

[0067] First, start the working roller 1 to ensure that the working roller 1 is in a stable rotating state. Secondly, start the reciprocating oil cylinder 310 to drive the brush roller 6 to start reciprocating axially and rotating radially. Subsequently, start the hydraulic cylinder 710, and the push rod 711 pushes the support frame 513 to rotate along the support shaft 512, thereby driving the brush roller 6 to move radially towards the working roller 1 along the working roller 1. At the same time, the support frame 513 drives the limiting rod 523 to slide in the limiting body 521 through the hinge seat 525. At this time, the limiting body 521 can rotate around the limiting bracket.

[0068] When the bristles 610 on the brush roller 1 contact the surface of the working roller 1, the limiting block 522 blocks the sliding of the limiting rod 523, thereby causing the brush roller 6 to stop moving towards the working roller 1, and completing the limiting of the brush roller 6 by the limiter 520. At this time, the bristles 610 reciprocate axially and rotate radially under the drive of the brush roller 6 to realize the cleaning of the impurities on the surface of the working roller 1.
