Accurate variable station number index plate mechanism and glassware production equipment

The utility model relates to the technical field of indexing turntables, in particular to an accurate variable station number indexing plate mechanism which comprises a transposition servo motor, a cam shaft and a turret, and the transposition servo motor provides power for the cam shaft; the cam shaft comprises a shaft rod and a cam located on the periphery of the shaft rod, the cam is in a continuous and uniform spiral shape, the rotating tower comprises a transmission disc and needle bearings fixed to the transmission disc, and the needle bearings are arranged around the center shaft of the transmission disc in a circumferential array mode. The cam is meshed with at least one needle bearing; the transposition servo motor is configured to operate intermittently to drive the cam shaft to rotate intermittently, the operation duration of each time is consistent, and the stopping duration of each time is also consistent. The station number of indexing and transposition of the turret is adjustable, and under the
