[0002] Filling and capping machines are mainly used for filling liquids or pastes in the fields of daily chemicals, food, and medicine. Most of the existing filling equipment has an integrated design, which can perform a series of processes such as filling, plugging, and capping, with high work efficiency.

[0003] Problems existing in the above patent: Before the existing swing arm pre-rotation device performs the capping action, the suction nozzle is controlled to rotate by a driving member, and the suction nozzle sucks it when it rotates to the capping position, and then the suction nozzle is reset to pre-rotate the bottle cap onto the bottle. In order to improve the assembly efficiency, the rotation speed of the turntable is usually adjusted to make the bottle body move to the swing arm pre-rotation station faster, but the action time of the swing arm pre-rotation station is relatively long, and it is difficult to match the rotation speed of the turntable.

[0006] As a preferred technical solution of the utility model, the first power component is provided with two groups corresponding to the first rotating arm and the second rotating arm respectively, each of the first power components includes a rotating motor and a driving wheel arranged on the output shaft of the rotating motor, and the first rotating arm and the second rotating arm are provided with a driven wheel at one end of the corresponding mounting plate, and the driving wheel and the driven wheel are linked.

[0007] As a preferred technical solution of the utility model, a rotating shaft for mounting a driven wheel is provided at one end of the first rotating arm facing the mounting plate.

[0008] As a preferred technical solution of the utility model, a three-claw cylinder is provided at one end of the first rotating arm opposite to the mounting plate.

[0009] As a preferred technical solution of the present utility model, the second power assembly includes a first drive motor for driving the mounting plate to rotate, and the output shaft of the first drive motor is connected to the mounting plate.

[0010] As a preferred technical solution of the utility model, the first driving motor is arranged on a fixed frame, and the third power assembly includes a lifting rod connected to the fixed frame, a transmission rod and a second driving motor that drives the transmission rod to rotate, a cam structure is arranged on the transmission rod, and the lower end of the transmission rod is linked to the cam structure, and the lifting rod moves up and down under the drive of the cam structure.

[0011] To sum up, the beneficial effects of the utility model are as follows: the bottle cap can be grabbed in advance by the first rotating arm and the second rotating arm, one rotating arm screws the cap while the other rotating arm grabs it, and the two actions are performed simultaneously. When the cap screwing action is required, the rotating arm with the bottle cap is shifted to the bottle body, and the other rotating arm after the shifting grabs the bottle cap at the same time. There is no need to return to the bottle body position after clamping like the traditional single-arm, which shortens the action time and can adapt to the bottle body turntable of the corresponding speed to improve the assembly efficiency.
