[0006] The above-mentioned quick-detachable roller structure of the present application is configured such that one end is configured as a fixed bearing assembly and the other end is configured as a movable bearing assembly.

The movable bearing assembly 23 is connected to the mounting frame 1 in an axially movable manner and is located at the other end of the roller roller 21, and the movable bearing assembly 23 has a rotatable second tapered shaft 231. The first tapered shaft 221 and the second tapered shaft 231 respectively form an axially detachable tapered matching structure with the two ends of the roller roller 21. The first telescopic drive member 24 is fixedly connected to the mounting frame 1, and is used to drive the movable bearing assembly 23 to axially telescopic movement, so that the second tapered shaft 231 is matched with or disengaged from the roller roller 21.

The mounting frame 1 is provided with four roller rollers 21 extending in the front and rear directions, and the four roller rollers 21 are distributed in the upper and lower layers with two rollers each.

[0034] Since one end is set as a fixed bearing assembly 22 and the other end is set as a movable bearing assembly 23, during disassembly, the first telescopic drive member 24 can drive the second tapered shaft 231 to separate from the roller roller 21, so that the roller roller 21 is in an active state, which makes disassembly convenient. Moreover, the roller roller 21 and the first tapered shaft 221 and the second tapered shaft 231 are all tapered, so that automatic alignment can be performed during installation, and installation is also extremely convenient.

[0035] In some embodiments, the interior of the roller roller 21 is a hollow structure, and tapered parts are fixedly provided at both ends of the axial direction, and the two tapered parts are mirror-imaged. The first tapered shaft 221 and the second tapered shaft 231 are respectively taper-matched with the two tapered parts. The interior of the roller roller 21 is also provided with a reinforcement pipe fitting 212, whose two ends are respectively fixedly connected to the two tapered parts.

[0037] In some embodiments, the tapered member may be as follows Figure 3-4 The tapered sleeve 211 shown may also be Figure 8 The bearing shell 213 shown in the figure has a tapered hole inclined surface with a certain curvature, so that the shaft and the bearing shell have a certain movable angle when they are matched, and the processing accuracy requirement of the shaft will be lower.

[0038] In some embodiments, the first telescopic drive member 24 is a first telescopic cylinder, which is fixedly arranged on a mounting plate 241, and the mounting plate 241 is fixedly connected to the mounting frame 1. The piston rod of the first telescopic cylinder is connected to the movable bearing assembly 23 and drives its telescopic movement. The movable bearing assembly 23 is fixedly provided with a first guide rod 242, and the mounting plate 241 is provided with a first guide sleeve 243 that cooperates with the first guide rod 242 for guidance. Since the movable bearing assembly 23 is a telescopic structure, the movable bearing assembly 23 is also provided with a first guide rod 242, and the mounting plate 241 is guided and matched with the first guide rod 242, which can effectively prevent the second tapered shaft 231 from driving the movable bearing assembly 23 to rotate as a whole during the rotation process. In order to prevent the movable bearing assembly 23 from rotating, a convex block portion can also be provided on the movable bearing assembly 23, and a groove is provided on the mounting frame 1, and the convex block portion and the groove are matched in a concave-convex manner.

[0039] In some embodiments, the mounting frame 1 is further provided with a roller disassembly mechanism 3 for axially pushing the roller roller 21 out from the first tapered shaft 221 .

[0040] In some embodiments, the roller disassembly mechanism 3 includes a disassembly top plate 31, a top cylinder 32, and a disassembly guide shaft 33. The disassembly top plate 31 is located at one end of the roller roller 21 close to the first tapered shaft 221. The top cylinder 32 is fixedly arranged on the mounting frame 1, and the piston rod of the top cylinder 32 is connected to the disassembly top plate 31 and drives its telescopic movement. The disassembly guide shaft 33 is fixed on the mounting frame 1, and the disassembly top plate 31 has a guide hole that cooperates with the disassembly guide shaft 33. When the disassembly top plate 31 of the roller disassembly mechanism 3 is pushed out, it can drive the roller roller 21 to move axially, so that the roller roller 21 is separated from the first tapered shaft 221. Compared with manual disassembly of the roller roller 21, the labor intensity can be reduced and the disassembly efficiency can be improved.

[0041] In some embodiments, the upper parts of the two lifting frames 41 are connected together by a cross beam 6, and a spray mechanism 7 is provided on the cross beam. The spray mechanism 7 includes a spray mounting beam 71 fixed to the cross beam 6, a spray frame 72 movably connected to the spray mounting beam 71 up and down, and a spray lifting mechanism 73 for driving the spray frame 72 to move up and down. The spray frame 72 includes a water inlet pipe 721 extending left and right, a support rod 722 arranged parallel to the water inlet pipe 721, and a plurality of spray rods 723 installed on the support rod 722.

The position of the spray rod 723 can be adjusted as needed to adapt to the cutting of multiple specifications of rough materials. In addition, the spray mechanism 7 is movable and retractable. When the mounting frame 1 descends, the height of the spray rod 723 can be adjusted accordingly, so that the spray water can be at a suitable height with the rough material, which can avoid the problem of the spray water being too high, thereby causing a poor spraying effect. In some embodiments, the second lifting drive component 5 can be a structure used in conjunction with a motor and a linear rail mechanism, wherein the installation position of the motor can be set on one side of the lifting frame 41 or in the middle of the two lifting frames.

[0043] The following briefly describes the working process and use method of a multi-wire cutting machine in the above embodiment:

[0044] The cutting process of the multi-wire saw is as follows: the cutting wire is spirally wound on four rollers 21, and a cutting mesh is formed on the two rollers 21 at the lower layer. When the stone is in place, the second lifting drive assembly 5 drives the mounting frame 1 to continue to press down, and the driving motor 25 drives the rollers 21 to rotate forward and backward, so that the cutting mesh can reciprocate and cut the stone. When the stone is cut, the mounting frame 1 extends upward, and the cut stone slab is withdrawn. In the process of the driving motor 25 rotating, the driving motor 25 first drives the first tapered shaft 221 to rotate. The first tapered shaft 221 and the roller 21 are tapered, and the friction force drives the roller 21 and the second tapered shaft 231 to rotate together.

[0045] The disassembly process of the roller roller 21 is as follows: the first telescopic driving member 24 drives the movable bearing assembly 23 to retract, so that the second tapered shaft 231 is separated from the roller roller 21, and the top cylinder 32 extends to drive the disassembly top plate 31 to be pushed forward, so that the roller roller 21 moves in the direction close to the second tapered shaft 231, thereby separating from the first tapered shaft 221, and completing the disassembly process. The installation process of the roller roller 21 is opposite to the disassembly process, so no further description is given.
