ABSTRACT:
A reciprocating and deflecting swing device for the roller of a cylindrical emery-polishing machine includes a motor fixing base having its inner side provided with a lower holder engaged thereon with an upper holder, with an emery-tape roller fitted in the upper holder. A shaft-coupling unit is connected between the shaft of a motor and the emery-tape roller. A speed-reducing device is installed with the motor fixing base, having an input terminal connected to the shaft-coupling unit by a belt. A rod-connecting unit is pivotally provided between the speed-reducing device and the upper holder. Power of the motor is transmitted to the emery-tape roller and the speed-reducing device respectively by the shaft-coupling unit and the belt. The rod-connecting unit is driven to actuate the upper holder and the emery-tape roller to swing to and fro biasly.
