Cap rotating mechanism for continuous round disc type cap rotating machine

Abstract

The unscrewing mechanism of a consecutive disk type unscrewing device driven by electric motor speed reducer for free rotation, flexible and convenient of operation and applicable of bottles of alls kinds of specifications, comprises of electric motor speed reducer, speed reducer gear, cam of the middle cylinder, upper gear, gear shaft, lower gear, gear, middle gear, middle gear base, drive shaft, friction clutch, central fixing shaft, and unscrewing head, with speed reducer gears equipped on the shaft end of the electric motor speed reducer, and upper gears, gear shaft and lower gears equipped on the middle cylinder cam. The gear shaft fastens on the middle cylinder cam through a bearing base; the middle gear tooths with gears that connect sequentially with the drive shaft, the friction clutch and an unscrewing head.

Description

Technical field: [0001] The invention relates to the technical field of packaging machinery, in particular to an improvement of a capping mechanism on a capping machine. Background technique: [0002] The capping mechanism of the continuous disc type capping machine in the prior art is: there is an intermediate gear above the middle cylindrical cam, and the intermediate gear is connected and fixed with the central fixed shaft of the capping machine through a key. A pinion is meshed around the middle gear, and the pinion is fixed on a transmission shaft, and a capping head is fixed at the lower end of the transmission shaft. When the capping machine disc rotates, the pinion around the intermediate gear rotates around the intermediate gear, thereby driving the capping head to rotate. The middle cylindrical cam controls the pinion, drive shaft and capping head to move up and down. Although the capping mechanism of this kind of capping machine can realize the function of cappi...

AI Technical Summary

Problems solved by technology

Although the capping mechanism of this kind of capping machine can realize the function of capping, there is the following problem: because the intermediate gear is fixed, the number of rotations of the pinion gear is also fixed when the disk rotates a circle, so the rotation The number of rotations of the capping head is also fixed when the capping disc rotates once.

Therefore, when the number of tightening circles of the bottle cap is large, it is easy to cause the phenomenon that the bottle cap is not tightly screwed; and when the number of tightening circles of the bottle cap is small, it is easy to cause the bottle cap to be over-tightened, and even make the bottle cap Scratches on the surface
