The capping arm includes a capping arm body 93 and a force gear 94 installed on the capping arm body. The intermediate gear is meshed with the inner side of the transmission gear ring, and the force gear is meshed with the outer side of the transmission gear ring. When the cap is being screwed, the power assembly drives the intermediate gear to rotate, the intermediate gear drives the transmission gear ring to rotate, the transmission gear ring drives the force gear, the force gear revolves around the center of the transmission gear ring while rotating around its own axis, the capping arm body and the force gear rotate synchronously to realize the capping action.

[0026] Through the above arrangement, the intermediate gear and the stressed gear are transmitted through the transmission gear, and the line between the center of the transmission gear and the center of the intermediate gear intersects with the line between the center of the transmission gear and the center of the stressed gear, thereby reducing the distance between the intermediate gear and the stressed gear, which is beneficial to reducing the orbital radius of the cap screwing arm, thereby reducing the space occupied by the cap screwing device.

[0027] In the present application, the base plate 1 is horizontally arranged above the sleeve 2, the intermediate gear 4 is fixed on the outer periphery of the sleeve 2, and the power component 3 can refer to the existing capping device; the annular support frame 6 is axially fixed on the sleeve 2, that is, the annular support frame 6 can only rotate on itself and cannot move up and down; when the capping device is working, the power component 3 drives the sleeve 2 and the intermediate gear 4 to rotate around the axis of the sleeve 2, and the intermediate gear 4 drives the transmission gear 5. The transmission gear 5 rotates around its own axis while revolving around the axis of the sleeve 2, and drives the annular support frame 6 and the capping arm 7 to rotate around the axis of the sleeve 2. In addition, the intermediate gear 4 drives the force gear 72 to rotate around its own axis through the transmission gear 5, and the force gear 72 drives the capping head 73 to realize the capping.

[0028] In this application, see Figure 5 The centers of the intermediate gear 4, the transmission gear 5 and the force gear 72 are not in a straight line, but are arranged in a triangular lattice, so that the distance from the center of the intermediate gear 4 to the center of the force gear 72 is smaller, thereby reducing the revolution radius of the capping arm 7, and further reducing the space occupied by the capping device.

[0034] In the present application, the lower end of the connecting rod 75 is locked on the shell 71 by a fastener, and the upper end of the shell 71 passes through the guide sleeve 9 and is slidably connected to the guide sleeve 9 to reduce the shaking of the connecting rod 75 and the shell 71 when moving up and down.

[0035] As an implementation method, the cap screwing device also includes an upper gear 10 coaxially fixedly connected to the upper end of the sleeve 2, the power assembly 3 includes a motor 31 installed on the upper side of the base plate 1, and a driving gear 32 installed on the output shaft of the motor 31, and the driving gear 32 is meshed with the upper gear 10.
