Description

Three-finger automatic bottle cap torque meter

Technical Field

The utility model relates to the technical field of torque value detection, in particular to a three-finger automatic bottle cap torque meter.

Background

The bottle cap opening torque is a torque value required for unscrewing the bottle cap and is a physical quantity representing the difficulty of opening the bottle cap. If the torque for opening the bottle cap is low, a certain risk is brought to the tightness of the package, and the phenomenon of liquid leakage and air leakage easily occurs. If the bottle cap opening torque is high, the bottle cap can be difficult to open.

The clamping mode is generally bilateral symmetry clamping, and the sample is generally fixed by using four clamping columns in a pneumatic or manual mode, but the coaxiality of the bottle cap and the bottle body clamped by the clamping mode is deviated, an external force is generated, and under the influence of the external force, the experimental result is fluctuated and inaccurate;

The lifting mode mostly adopts manual lifting, positioning bottle cap precision is poor, the testing process is semi-automatic, full-automatic testing can not be realized, and the testing precision is generally poor while manual work is consumed.

Therefore, we propose a three-finger automatic bottle cap torque meter to solve the existing problems.
