[0026] In the embodiment of the utility model, the rotating member 9 includes: a capping head 901, a rotating shaft 902, a connecting plate 903 and a limiting member 904. The top of the second magnet 7 is connected to the connecting plate 903, the center of the connecting plate 903 is connected to the rotating shaft 902, the top of the rotating shaft 902 is connected to the limiting member 904, the bottom of the second limiting plate 5 is centrally installed with a limiting member 904, the bottom of the rotating shaft 902 is connected to the capping head 901, and the center of the rotating member 9 is provided with a capping passage that fits with the capping ejector rod 1.

[0031] In the embodiment of the utility model, the first magnet 6 and the second magnet 7 include a plurality of rectangular magnetic strips, which are vertically arranged and arranged in a ring shape. The magnetism of the outer sides of adjacent magnetic strips is different, so that the second magnet 7 drives the first magnet 6 to rotate when the second magnet 7 rotates.

[0032] Working principle: when in use, the capping machine drives the main shell 3 to rotate, and the main shell 3 drives the fixing part 11 to rotate, and then the fixing part 11 will rotate with the adjusting block 8, and then the adjusting block 8 drives the second magnet 7 at the top to rotate, and under the action of the magnetic force of the magnet, the second magnet 7 drives the first magnet 6 to rotate when it rotates, and the first magnet 6 is connected to the connecting plate 903, and when the first magnet 6 rotates, it will drive the connecting plate 903 to rotate, thereby driving the rotating part 9 to rotate, so that the capping head 901 at the bottom end of the rotating part 9 rotates, and the capping head 901 contacts the bottle cap, driving the bottle cap to rotate, thereby tightening the bottle cap; when the bottle cap is tightened, the capping machine moves the cap pushing rod downward to separate the bottle cap from the capping head 901, and at the same time, the capping spring 13 is compressed under the action of the limit block 14, and when the capping machine stops and the capping rod moves downward, the compressed capping spring 13 will lift the capping rod to reset. , the connecting spline 1101 and the spline groove preliminarily connect the main shell 3 and the fixing part 11, so that when the main shell 3 rotates, it can drive the connecting spline 1101 to rotate, and the positioning bolt 10 further connects and fixes the main shell 3 and the fixing part 11. The positioning bolt 10 fixes the position of the fixing part 11, avoiding the problems of gap wear, equipment vibration and loud operation noise caused by the gap in the spline of the fixing part 11 when the device rotates, extending the service life of spare parts, eliminating food contamination, and avoiding major equipment accidents. When the torque needs to be adjusted, the adjusting block 8 is rotated. Under the action of the connecting thread and the adjusting thread 1102, the adjusting block 8 moves upward or downward, thereby driving the second magnet 7 connected to the top of the adjusting block 8 to move, so that the attraction between the first magnet 6 and the second magnet 7 changes, thereby causing the maximum torque when the second magnet 7 drives the first magnet 6 to rotate to change.
