Problems solved by technology
The capping torque is controlled by the return spring. Although this device has many advantages, due to the frequent friction between the steel ball used for positioning and the limit hole, the wear is serious, and it needs to be updated regularly, and the elastic force of the return spring is also unstable. If it is too long, it will easily lead to failure, and the transmission torque will be easily distorted after the steel ball for positioning is worn out, resulting in defects such as loose screw cap

Disclosed is a magnetic force moment-limiting rotary capping device for a rotary capping machine, which comprises a rotary main shaft, a connecting nut, an upper sleeve base, an upper magnetic ring base, an upper magnetic block, a lower magnetic block, a lower magnetic ring base, a connecting sleeve, a compression rod, a cover pressing cushion, a rotary cap, an elastic ring, an upper bearing, a driven spindle, a lower bearing, a spring and a screw; the lower end of the upper magnetic ring base is lined with the upper magnetic block; the upper end surface of the lower magnetic ring base is lined with the lower magnetic block; the lower magnetic ring base is fixedly connected with the rotary cap; the lower magnetic block is corresponding to the upper magnetic block; because the cover screwing moment is transferred through the magnetic force, the gap between the upper magnetic block and the lower magnetic block is adjusted to satisfy the constant moment cover screwing requirements of thebottle cover with different specifications.
Description
Technical field: [0001] The invention relates to a bottle packaging and capping machine, in particular to a capping device. Background technique: [0002] The capping machine for bottle filling is equipped with a capping device. A capping machine is usually equipped with a variety of different specifications of capping joints to meet the tightening requirements of different specifications of bottle caps. The capping joints are composed of rotating sleeves. It is composed of a soft pressure pad. The upper end of the rotating sleeve is provided with a taper hole corresponding to the Morse taper of the driving spindle, and the lower end is provided with a step hole for installing the soft pressure pad. The soft pressure pad is set in the step hole at the lower end of the rotating sleeve. Different specifications Bottle caps must be replaced with different capping joints, and the machine must be shut down to remove and install the capping joints every time it is replaced. This is not...
