The wire binding roll is placed inside the electric hand-held reinforcing steel bar binding machine, as shown in fig. 1, in consideration of the feasibility of manual operation and the limitation of structural capacity of the reinforcing steel bar binding machine, the used wire binding is the wire binding roll wound into small rolls, the wire binding winding ratio is small, and for example, each roll of the wire binding roll is only 100 meters.
With the widespread popularization and gradual deepening of the assembly type building, further requirements are made on the intellectualization of an assembly type building factory, and the realization of the automation of the production of assembly type building accessories is urgent. The fitting of the prefabricated building is mainly a reinforced concrete structure, wherein the steel bar binding is a vital step in the actual production, and the realization of the automation of the steel bar binding has important significance.
The prior reinforcing bar binding machine has a plurality of limitations when applied to an automatic device, one of which is the problem of continuity of the supply of binding wires by the reinforcing bar binding machine on the automatic device, so that the problem of continuity of the supply of the binding wires is solved by using a large-coil binding wire coil on the reinforcing bar binding machine on the automatic device, and a plurality of new problems are generated by adopting the large-coil binding wire coil. The problems are as follows:
1. the wire binding roll adopting the large roll needs to be externally arranged on the steel bar binding machine due to the large weight and volume, so that the required rotating resistance for driving the large roll of the wire binding roll is large, the wire feeding mechanism of the existing steel bar binding machine cannot directly draw out the binding wire from the wire binding roll in a traction mode, namely, when the wire feeding mechanism of the steel bar binding machine feeds the wire, a wire feeding wheel of the wire feeding mechanism slips with the binding wire, and the binding wire cannot be drawn out from the large roll of the wire binding roll. If the existing wire feeding mechanism of the steel bar binding machine is adopted, an additional auxiliary mechanism, such as an auxiliary power paying-off device for paying off binding wires from a large binding wire coil, is added at the moment, so that the defects of the wire feeding mechanism of the steel bar binding machine are overcome, and the binding wires are sent out from the steel bar binding machine.

2. Or the wire feeding mechanism can drive the wire bundling coil, but the wire feeding mechanism can not stably draw out the bundling wire from the large wire bundling coil, so that the phenomena of looping failure, looping drift instability and the like of the bundling wire of the steel bar bundling machine occur in the looping process, the success rate of the use of the steel bar bundling machine is low, the use is unstable, and the automation cannot be stably and effectively realized.
3. Or the wire feeding mechanism can drive the wire bundling coil, namely the wire feeding mechanism has enough capacity to draw the bundling wire out of the large wire bundling coil, and the looping of the steel bar binding machine is relatively stable, but the wire feeding mechanism has overlarge wire feeding wheel assembly clamping force of the wire bundling, so that the wire bundling is easily damaged, thinned or otherwise bad, after the looping of the steel bar binding machine and during twisting, the maximum tightness of the steel bar which can be tightly bundled by the damaged bundling wire will be reduced, the twisting of the wire is easily broken due to overlarge binding force, and the twisting is not tight if the twisting force is reduced, so that the bundling failure is caused.
The existing steel bar binding machine adopts a pair of wire feeding wheels to clamp binding wires, the binding wires are conveyed through the wire feeding wheels, a wire feeding mechanism of the steel bar binding machine enables the binding wires to be drawn out from a binding wire coil, and finally a binding wire ring for binding steel bars is formed through a guide mechanism.
