Abstract

The invention relates to an eccentric turntable comprising a base. The base is provided with a rotating shaft. The rotating shaft is mounted in a bearing block through a bearing. The bearing block is fixedly connected with a rotating frame through bolts. The eccentric turntable is characterized in that the rotating shaft is eccentric to the center of the rotating frame; an outer rail and an inner rail are arranged in the peripheral direction of the rotating shaft, the bottom of the rotating frame is provided with a plurality of travel guide wheel components along the inner and outer rails; each travel guide wheel component comprises a travel rack mounted at the bottom of the rotating frame, a guide wheel shaft is mounted on each travel rack through a bearing, a travel guide wheel is fixed on each guide wheel shaft, and the travel guide wheels are disposed on the corresponding outer and inner rails; a travel motor is mounted on the travel rack of one travel guide wheel component mounted on the outer rail, and an output shaft of the travel motor is connected with the corresponding guide wheel shaft. The eccentric turntable which is eccentric has the advantages that equipment space is saved, noise is reduced and daily maintenance of equipment is greatly facilitated.
