Capping machine claw head

Abstract

The invention relates to a cap-screwing machine chuck, which is used for clamping a bottle cap. The cap-screwing machine chuck comprises a plurality of jaws, a jaw base and a pusher; the jaws are used for clamping the bottle cap; the jaws are evenly mounted around the jaw base; the pusher is used for pushing the jaws to move, and can push the jaws to shift oppositely or relatively under the action of power. The cap-screwing machine chuck adopts wedge structures to drive the jaws to shift for grabbing and releasing, changing the conventional way of action which drives the jaws to swing for grabbing and releasing; the jaws of the cap-screwing machine chuck are always stressed for clamping in the horizontal direction, while the conventional jaw has an articulating point and the characteristic of articulation is utilized to swing the jaw, which is equivalent to lever motion, so the grabbing force and stability of the conventional jaws are not as good as the grabbing force and stability of the cap-screwing machine chuck; moreover, the design of the mechanism for driving the jaws to move is simplified, so the entire machine becomes more excellent and the cost is reduced.

Description

technical field

[0001] The invention relates to the technical field of capping machines, in particular to provide a fast and reliable claw head of the capping machine for the capping machine's structure of grasping caps. Background technique

[0002] The automatic capping machine is a device that can screw the cap on the bottle body. It is widely used in daily chemical, food, medicine and other industries. Its structure generally includes a frame, a power transmission device and a capping assembly. There is a rotating part in the cap assembly, and the power device drives the rotating part to rotate. The bottle cap is stuck in the chuck of the rotating part. With the rotation of the rotating part, the bottle cap is tightened on the bottle body. It is a claw structure. For example, application number 201210474244.4 discloses a capping device on a capping machine. The capping device uses a push rod to push the claws to achieve opening and tightening. Although it can also grasp ...
