[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] Please see Figure 1-4 A furnace roller assembly device for an annealing furnace. The technical solution proposed in this utility model includes a connecting plate 1, a rotating roller assembly 2 at the middle of the connecting plate 1, a plurality of rotating rollers 21 equidistantly arranged at the middle of the connecting plate 1, two sets of mounting blocks 22 symmetrically arranged at the front and rear ends of the rotating rollers 21, a mounting sleeve 23 sleeved on the lower end of the mounting block 22, a first bolt 26 threadedly inserted into the upper end of the mounting block 22, and a first motor 3 connected to the upper end of the outer wall of the connecting plate 1.

[0024] The upper end of the mounting sleeve 23 has a mounting groove 24 that mates with the mounting block 22. The mounting block 22 is movably inserted into the mounting groove 24. The lower end of the mounting sleeve 23 located in the mounting groove 24 has a mounting hole 25 that mates with the first bolt 26. The lower end of the first bolt 26 passes through the mounting block 22 and is threaded into the mounting hole 25. The end of the mounting sleeve 23 away from the rotating roller 21 is rotatably connected to the inner wall of the connecting plate 1.

[0025] The drive assembly 4 includes a rotating shaft 41 fixedly disposed at one end of one of the mounting sleeves 23. The rotating shaft 41 passes through the connecting plate 1 and is rotatably connected to the connecting plate 1. A sprocket 42 is fixedly connected to the end of the rotating shaft 41 away from the mounting sleeve 23. A chain 43 is wrapped around the outer wall of the sprocket 42, and the chain 43 and the sprocket 42 mesh with each other.

[0026] The output end of the first motor 3 is fixedly connected to one of the mounting sleeves 23.

[0027] After the roller 21 is used, it needs to be disassembled for easy cleaning and maintenance. The first bolt 26 can be rotated to unscrew the lower end of the first bolt 26 from the mounting hole 25. Then, the roller 21 is lifted upward so that the mounting blocks 22 at both ends of the roller 21 are separated from the mounting sleeve 23. The roller 21 can be disassembled from the middle of the connecting plate 1 in sequence according to the above operation. During the use of the roller 21, the first motor 3 can be started to drive one set of mounting blocks 22 to rotate. The mounting blocks 22 drive the rotating shaft 41 to rotate, and the rotating shaft 41 drives the sprocket 42 to rotate. Under the action of the chain 43, the other sets of sprockets 42 rotate in the same direction, so that the roller 21 rotates in the same direction at the same speed. The conveying operation is carried out by the rotation of the roller 21.

[0028] Please see Figure 1-5 A drive assembly 4 is provided on the outer wall of the connecting plate 1 away from the first motor 3. A cleaning assembly 5 is provided on the inner wall of the connecting plate 1 at the lower end of the roller assembly 2. The cleaning assembly 5 includes two sets of fixing plates 501 fixedly disposed on one side of the outer wall of the connecting plate 1. A second motor 502 is provided on the outer wall of one set of fixing plates 501. A ball screw 503 is connected to the output end of the second motor 502. A ball sleeve 505 is sleeved on the outer wall of the ball screw 503. A receiving plate 508 is provided on the upper end of the ball sleeve 505. A cleaning brush 510 is provided on the upper end of the receiving plate 508.

[0029] A slide rod 504 is fixedly provided at the front end of the fixed plate 501 away from the ball screw 503. A slide sleeve 506 is movably sleeved on the outer wall of the slide rod 504. A fixed block 507 is provided at the end of the ball screw 503 and the slide rod 504 away from the second motor 502. The ball screw 503 and the slide rod 504 are rotatably connected to the fixed block 507. The fixed block 507 is rotatably connected to the fixed plate 501.

[0030] A receiving plate 508 is fixedly provided on the upper end of the ball sleeve 505 and the sliding sleeve 506. A receiving groove 509 is provided on the upper end of the receiving plate 508. A cleaning brush 510 is movably inserted in the middle of the receiving groove 509.

[0031] A second bolt 511 is threaded into the middle of the outer wall of the receiving plate 508. The second bolt 511 moves from the outside to the inside through the receiving plate 508, the receiving groove 509 and the cleaning brush 510. The upper end of the cleaning brush 510 is parallel to the lower end of the rotating roller 21.

[0032] A collection box 6 is movably inserted into the inner wall of the lower end of the connecting plate 1. Insert blocks 7 are fixed at both ends of the collection box 6. The inner wall of the connecting plate 1 has slots that cooperate with the insert blocks 7.

[0033] When the roller 21 is in operation and there is residue adhering to its outer wall, the second motor 502 can be started to rotate, driving the ball screw 503 to rotate. The rotation of the ball screw 503 can drive the ball sleeve 505 to move along the ball screw 503 towards the fixed block 507. During this movement, the upper end of the cleaning brush 510 moves along the lower end face of the roller 21. When the cleaning brush 510 contacts the roller 21, the roller 21 is also rotating, so the cleaning brush 510 can clean the residue adhering to its outer wall. After the ball sleeve 505 contacts the fixed block 507, the second motor 502 is started in reverse, causing the ball sleeve 505 to move towards the fixed plate 501. This process is repeated multiple times, so that the cleaning brush 510 can clean the outer wall of the roller 21 during its operation. The cleaning brush 510 can clean the adhering substances without stopping the machine to clean the roller 21. The sliding sleeve 506 and sliding rod 504 increase the stability of the cleaning brush 510 during movement. In addition, the cleaned adhering substances will fall into the collection box 6. When it is necessary to clean the adhering substances in the collection box 6, the collection box 6 can be pulled outward, so that the insert block 7 slides along the slot opened in the inner wall of the connecting plate 1, and the collection box 6 can be pulled out for easy processing of the adhering substances in the collection box 6. When the cleaning brush 510 needs to be cleaned or replaced after long-term use, the second bolt 511 can be rotated so that the second bolt 511 is disengaged from the receiving plate 508. Then the cleaning brush 510 can be lifted upward, so that the lower end of the cleaning brush 510 is pulled out from the receiving groove 509, thereby facilitating the replacement or cleaning of the cleaning brush 510.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
