<p>An anti-rotation device for a gripping member of a mixing machine for fluid products contained in a closed container. The mixing machine comprises a fixed structure and the gripping member comprises a supporting structure rotary with respect to the fixed structure and on which two gripping elements are mounted, able to be selectively moved nearer to or farther from each other by means of a screw, in order to determine the temporary clamping of the container with respect to the supporting structure. The device comprises clamping members associated coaxially with the screw in order to keep the screw temporarily constrained angularly with respect to the supporting structure of the gripping member, and unclamping members mounted on the fixed structure in order to be selectively moved, so as to cooperate with the screw, so as to de-activate the action of the clamping members and to de-constrain the angular movement of the screw with respect to the supporting structure, and actuation members able to automatically and selectively command both the unclamping members and also the clamping members.</p> |
