Scroll braking device of full-automatic steel bar strapping machine and same

Abstract

The invention discloses a scroll braking device of a full-automatic steel bar strapping machine and the same. The scroll braking device comprises a braking seat, a braking block, a braking shaft and a power part, wherein the braking block is mounted on the braking seat, the braking shaft drives the braking block, and the power part drives the braking shaft. The scroll braking device is characterized in that the braking block is hinged to the braking seat through a hinge shaft; the braking block forms a braking end and a driving end with the hinge shaft serving as a dividing line; the braking end is suitable for making contact with an outer scroll to conduct braking; the power part pushes and pulls the braking shaft to move along the axis; a driving inclined plane is arranged on the braking shaft; the driving end slides along the driving inclined plane; and when the braking shaft moves along the axis, the driving inclined plane pushes the driving end and enables the braking end to swing. The scroll braking block adopts the lever principle, easiness and efficiency are achieved, the response speed is fast, and the braking efficiency is high.

Description

technical field [0001] The invention relates to equipment in building construction, in particular to a steel bar binding machine for binding steel bars and a wire disc braking device installed thereon. Background technique [0002] The working principle of the fully automatic steel bar binding machine in the prior art is to send the steel wire to the loop forming mechanism through the wire feeding mechanism, so that the steel wire forms one or more closed steel wire loops around the steel bar that needs to be tightened, and then the steel wire The ring is tightened to achieve the effect of tightening the steel bars. During the wire feeding process, the steel wire tightly wound on the wire reel will drive the wire reel to rotate at a high speed. When the wire feeding stops, the wire reel will continue to rotate under the action of inertia, resulting in the loosening of the steel wire tightly wound on the wire reel. It will affect the next wire feeding, and even cause the wir...

During the wire feeding process, the steel wire tightly wound on the wire reel will drive the wire reel to rotate at a high speed. When the wire feeding stops, the wire reel will continue to rotate under the action of inertia, resulting in the loosening of the steel wire tightly wound on the wire reel. Affect the next wire feeding, and even cause the wire reel to be stuck
