Abstract

The invention discloses a cap rotating mechanism, which comprises a cap rotating main body, a rotating shaft and a cap grasping head, wherein the rotating shaft rotates in the cap rotating main body and is also fixedly connected with the cap grasping head, the cap rotating mechanism also comprises a magnet fixing seat and a disc-shaped rotor, the magnet fixing seat and the cap rotating main body are fixed, an upper magnet or a lower magnet is fixedly arranged on the magnet fixing seat, the upper magnet is positioned above the disc-shaped rotor, or the lower magnet is positioned under the disc-shaped rotor, each of the upper magnet and the lower magnet comprises an N magnetic region and an S magnetic region, the N magnetic regions and the S magnetic regions are in staggered arrangement, and the disc-shaped rotor is fixed with the rotating shaft. The magnet is arranged above or under the magnet fixing seat, and in addition, the N magnetic region and the S magnetic region in adjacent arrangement generate effective magnetic fields on the disc-shaped rotor, so that the cap grasping head generates a certain amount of overload torque, the transition of the cap grasping head overload torque is smooth, the operation is stable, and the high-speed operation of the cap grasping head can be realized.

Description

technical field [0001] The invention relates to the technical field of packaging, in particular to a screw cap mechanism. Background technique [0002] The capping mechanism in the prior art is provided with two circles of active magnets and driven magnets which are evenly distributed in an annular shape. The active magnets are installed on the capping body. When the capping machine drives the capping mechanism to rotate, the capping body drives the active magnet to rotate. , The driven magnet installed on the rotating shaft rotates under the drive of the magnetic force. When the cap screwing mechanism is screwing the cap, the cap grasping mechanism installed on the rotating shaft will screw the cap onto the bottle under the drive of magnetic force. When the cap is screwed tightly, the cap is fixed on the bottle, so that the driven magnet, the rotating shaft, the cap gripping mechanism and the cap stop rotating, and the active magnet keeps rotating with the main body of the...
