[0028] This solution can be realized. When the roller assembly of the multi-wire cutting machine is used for a long time and the steel wire rubs against the main shaft 3 to cause damage to it, after fixing the main shaft 3 by the lifting mechanism, the secondary shaft 1 and the secondary shaft sleeve 2 are inserted into the first screw hole and the second screw hole through the bolt 6 to be threaded and fixed, and then the fastening nut 10 is inserted into the secondary shaft 1 to compress the disc spring 9, and is clamped on the screw 7 by a hydraulic device, which has the function of locking the nut to prevent rotation, and then the secondary shaft sleeve 2 is pulled out so that the pin 11 is pulled out from the pin hole 12, so that the screw 7 is pulled out along with the secondary shaft sleeve 2 and the secondary shaft 1. The main shaft 3 is taken out from the main shaft 3. At this time, the main shaft 3 can be taken out and replaced with a new one. After replacement, the screw 7 is inserted into the main shaft 3 so that the screw 7 is threadedly fixed to the other secondary shaft 1. At this time, the spherical surface 8 is engaged with the main shaft 3, and the secondary shaft 1 and the main shaft 3 are fixed by the engagement of the latch 11 and the latch hole 12, so that the screw 7 rotates and drives the main shaft 3 to rotate at the same time. Subsequently, the fastening nut 10 is taken out to release the screw 7 so that it can rotate, thereby completing the replacement of the main shaft 3, and effectively achieving the effect of convenient and fast disassembly and assembly of the roller assembly of the multi-wire cutting machine to replace the main shaft 3.

[0029] The second implementation method:

[0030] Figure 1 and Figure 6-7It is shown that the main shaft 3 is detachably connected to a lifting mechanism, which includes a lifting rod 13, a connecting plate 14 is fixedly connected to the bottom end of the lifting rod 13, a sliding groove 19 is symmetrically bored at the bottom end of the connecting plate 14, an electric slide rail is fixedly connected in the sliding groove 19, a sliding rod 16 is symmetrically slidably connected to the electric slide rail, a clamp 15 is fixedly connected to one end of the two sliding rods 16 that are close to each other, and the two clamps 15 are engaged with each other, a clamp block 18 is fixedly connected to the side end of the clamp 15, a clamp groove 17 corresponding to the clamp block 18 is bored at the side end of the other clamp 15, and the clamp block 18 is engaged with the clamp groove 17.

[0031] This solution can be achieved. When the main shaft 3 is replaced, the lifting rod 13 can be raised and lowered to adjust the clamp 15 so that the clamp 15 is located on the main shaft 3. Then the electric slide rail is turned on to drive the slide rod 16 to drive the clamp 15 to move closer to each other, thereby clamping the main shaft 3. At the same time, the clamp block 18 and the clamp groove 17 are engaged to limit the two clamps 15. At this time, the secondary shaft 1 on the side end of the main shaft 3 can be disassembled, so that the screw 7 can be pulled out of the main shaft 3, so that the lifting rod 13 drives the clamp 15 to remove the damaged main shaft 3, and then the new main shaft 3 is placed in place, and the screw 7 and the secondary shaft 1 are reset, effectively achieving the effect of fully automatic loading and unloading.

[0032] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
