Abstract
A rebar tying machine wire feeding disc braking mechanism with positioning device has a braking part for stopping a wire feeding disc and a cam mechanism for controlling actions of the braking part. The cam mechanism has a cam and a push shaft mounted on a fixed seat, capable of axial displacement. One end of the push shaft presses against a rim of the cam and reciprocates along with the changing outline of the rim. A middle portion of the push shaft is a diameter-varying segment and presses against one end of the braking part such that the braking part swings forwards and backwards with the translation of the push shaft, the cam mechanism realizes stopping through the positioning device. The forward rotation inertia of the cam is eliminated such that the cam is stopped.
