In actual use, the whole production line still needs to be stopped when operating for plastic bottles of different heights, and the position of the lifting mechanism movement needs to be adjusted manually, which is inconvenient for maintenance. By setting a plastic bottle lifting seat and a lifting motor, the plastic bottle can be pushed upward onto the bottle cap clamp, and then the bottle cap clamp clamps the bottle cap, and the lifting motor provides sufficient upward thrust to provide the friction required for rotation.

[0024] The present invention is used for the filling and capping machine of plastic bottles for capsule packaging, which improves the existing technology. In actual use, there is still the situation that when operating for plastic bottles of different heights, the whole production line needs to be stopped, and the position of the lifting mechanism movement needs to be adjusted manually, which is inconvenient for maintenance. By setting the plastic bottle lifting seat 10 and the lifting motor 11, the plastic bottle can be pushed upward onto the bottle cap clamp 8, and then the bottle cap clamp 8 clamps the bottle cap, and the lifting motor 11 provides sufficient upward thrust to provide the friction required for rotation, and the clamp rotates to tighten the bottle cap.

When working, the driving motor 7 can be set to automatically stop when the torque load reaches a certain value a to avoid over-twisting and causing the bottle cap to slip. The lifting motor 11 can be set to maintain when the torque load reaches a certain value b when it moves upward to provide sufficient friction to twist the bottle cap.
