Problems solved by technology
The magnetic component used to drive the rotation of the capping mold in the traditional capping head with the above structure has a large fluctuation range of the pulsed torsion force formed during the capping slippage, so that the required uncapping force for the beverage bottle after capping is not large. Constant, resulting in poor opening comfort for consumers

Embodiment Construction
[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0016] Such as figure 1 , figure 2 As shown, the magnetic assembly used to drive the rotation of the capping mold in the capping head includes: two annular disks 2 that are set on the sleeve 1 at intervals up and down. Each disk 2 is successively divided into an annular magnetic area 21 and an installation area 22 from the outside to the inside. The annular magnetic area 21 on each magnetic disk 2 is evenly divided into several fan-shaped unit magnetic areas 211 around the circumference. Each fan-shaped unit magnetic area The two magnetic poles (N pole and S pole) of 211 are distributed up and down, and the angles of the central angles of each sector unit magnetic area 211 are greater than or equal to 3° and less than or equal to 10°. In this embodiment, the angle of the central angle of each sector unit magnetic region 211 is pre...

The invention discloses a magnetic assembly for driving a cap screwing mold to rotate in a cap screwing head. The magnetic assembly comprises two magnetic discs mounted on a shaft sleeve in a sleeving manner. A magnetic area on each magnetic disc is evenly divided into a plurality of sector-shaped unit magnetic areas around the circumference. The central angle corresponding to each sector-shaped unit magnetic area is larger than or equal to 3 degrees and smaller than or equal to 10 degrees. Two magnetic poles of the same ends of every two adjacent sector-shaped unit magnetic areas on each magnetic disc are opposite. The magnetic pole of each sector-shaped unit magnetic area on each magnetic disc is formed in a magnetizing manner. The upper magnetic disc is fixedly connected with the shaft sleeve. The lower magnetic disc is fixedly mounted on a shell sleeve. The shell sleeve is mounted on the shaft sleeve in a sleeving manner. The shaft sleeve is fixedly connected with the cap screwing mold. The shell sleeve can drive the magnetic disc fixedly connected with the shell sleeve to rotate. The cap screwing mold rotates under the action of magnetic attraction. The magnetic assembly has the beneficial effects that the fluctuation range of impulse type twisting force formed by magnetic force on bottle caps during cap screwing sliding is greatly narrowed, and the comfort degree of the cap opening hand feeling of a consumer is effectively ensured.
Description
technical field [0001] The invention relates to the technical field of capping machines in beverage filling equipment, in particular to a capping head in the capping machine. Background technique [0002] The function of the capping machine is to screw the bottle cap on the filled beverage bottle, that is, to cap it. The capping head is the main working part in the capping machine. When capping, the capping mold sleeve in the capping head is pressed on the bottle cap of the bottle mouth of the beverage bottle, and the capping mold rotates to drive the bottle cap to be screwed tightly on the bottle mouth of the beverage bottle. At present, one way to drive the rotation of the capping mold in the capping machine is through magnetic attraction. The magnetic component used to drive the rotation of the capping mold in the traditional capping head, its structure includes: the upper and lower intervals are set on the shaft sleeve, the annular upper magnetic column seat and the lo...
