when the power transmission assembly is the gear transmission assembly, the power transmission assembly comprises a first transmission gear and a second transmission gear which are meshed with each other, the first transmission gear is connected with the output end of the sand paper roller driving motor, and the second transmission gear is connected with the sand paper roller shaft.
8. The non-dismantling high-precision repairing device for large roller shafts as claimed in claim 7, wherein when the power transmission assembly is a synchronous pulley assembly, one side of the synchronous belt is further provided with a tension assembly, the tension assembly comprises a tension pulley, a tension pulley fixing plate, a tension pulley cylinder and a guide plate, a cylindrical surface of the tension pulley is connected with the synchronous belt, one end of the tension pulley is arranged on the tension pulley fixing plate, a side surface of the tension pulley fixing plate is connected with the tension pulley cylinder, a V-shaped guide block is arranged on a back surface of the tension pulley fixing plate, a V-shaped guide groove is arranged on the guide plate, and the V-shaped guide block is slidably connected with the V-shaped.
9. The disassembly-free high-precision repairing device for the large roller shaft as claimed in claim 1, wherein the surface of the sand paper roller is wound with fine sand paper, and the fine sand paper is distributed on the sand paper roller in a symmetrical herringbone manner along the direction from the middle part of the sand paper roller to the two ends.
10. The repairing device of any one of claims 1 to 9, which implements a disassembly-free high-precision repairing method for a large roller shaft, wherein when the center distance between the sand paper roller and the rubber cushion roller needs to be adjusted and the surface of the rubber cushion roller needs to be repaired, an eccentric fine-tuning mechanism is firstly used for adjusting the center distance between the sand paper roller and the rubber cushion roller, and the method specifically comprises the following steps: the turbine is rotated to drive the sand paper roller adjusting shaft to rotate, the sand paper roller adjusting shaft drives the first eccentric gear and the second eccentric gear to rotate through the first adjusting gear and the second adjusting gear, and at the moment, the sand paper roller and the sand paper roller shaft only horizontally move but do not rotate, so that the center distance between the sand paper roller and the rubber cushion roller is adjusted; and then, the sand paper roller driving mechanism is used for driving the sand paper roller shaft to rotate, so that the sand paper roller and the rubber pad roller generate relative rotation motion, and the friction between the sand paper roller and the rubber pad roller is utilized for grinding and repairing the surface of the rubber pad roller.
