Binding machine of reinforced bars

Abstract

The invention relates to a binding machine of reinforced bars, which comprises a machine frame, wherein a wire delivery mechanism and a winding mechanism are arranged on the machine frame. The wire delivery mechanism comprises a wire delivery arm and a wire receiving arm, wherein the wire delivery arm and the wire receiving arm are respectively positioned at both sides of a working platform face,a guide rail is respectively arranged in the wire delivery arm and the wire receiving arm, wire delivery chains are arranged in the guide rails, the head ends of the wire delivery chains are providedwith wire hooking heads, and a wire delivery driving device is connected on the wire delivery chains; the winding mechanism comprises a wire spool, wherein one side of the wire spool is provided witha clamping hook, and the clamping hook is over against the wire receiving arm; the other side of the wire spool is provided with a winding head, and the winding head is positioned at the back side ofthe wire delivery arm; the wire spool is also provided with a blade used for shearing off a wire at the back side of the winding head; and a winding driving device is connected on the wire spool. Theinvention has reasonable, simple and clear structure and convenient operation, can automatically bind reinforced bars together, is suitable for a common worker, can also work for a long time, can notgenerate the phenomenon of wire spill, enhances the working efficiency effectively and is suitable for large-range popularization.

Description

technical field [0001] The invention relates to a construction tool, in particular to a steel bar binding machine which can work with high efficiency for a long time. Background technique [0002] In construction projects, it is often necessary to bind cross-arranged steel bars with metal wires. Binding steel bars is labor-intensive. It is often difficult to improve work efficiency by manual binding alone, and it also wastes a lot of human resources. The structure of the steel bar binding tool on the market is comparatively complicated at present, and ordinary workers are difficult to repair minor faults, and it is inconvenient to use. For example, the steel bar binding machine disclosed in Chinese patent ZL200720059148.8 in its background technology mainly relies on the arc guide device to wind the metal wire into an arc when binding, thereby binding the steel bar. After the steel bars are bound, a tightening device is placed on the right side to tighten the wires. Becaus...

AI Technical Summary

Problems solved by technology

Since the tightening device needs space to enter and exit, this arc-shaped guide device is open and does not completely surround the steel bars to be bundled, so it cannot ensure that the wires are completely tied to the steel bars, and the use effect is not good

Moreover, the wire binding disc of this kind of steel bar binding machine often rotates due to inertia, causing the phenomenon of metal wire overflowing the disc.

In addition, other strapping tools without wire binding discs are complicated to operate and cannot work efficiently
