A portable steel bar automatic wire binding machine

Abstract

The invention discloses a portable rebar automatic wire-binding machine which comprises a casing, a controller, a wire feeding mechanism and a screwing shearing mechanism. The front end of the casingis provided with a tightening base and a wire-binding opening ring, an arc-shaped wire guide groove is disposed in the wire-binding opening ring, and the lower front end of the casing is provided witha wire feeding box. An iron wire roller and a wire feeding mechanism are mounted in the wire feeding box. The screwing shearing mechanism comprises a screwing driving wheel, a screwing driven wheel,a driven wheel shaft, pressing rods and a shearing rod. A pawl, a ratchet wheel with part of teeth and a fan-shaped restoration block are arranged between the screwing driving wheel and the screwing driven wheel. First an iron wire is sent by the wire feeding mechanism to surround a to-be-bound rebar; through relative rotation and stopping of the screwing driving wheel and the screwing driven wheel, the iron wire reaches the upper and lower pressing rods and the shearing rod, the upper end and the lower end of the iron wire are clamped through the upper and lower pressing rods and the shearingrod respectively, and then the screwing driving wheel and the screwing driven wheel rotate together to tighten and shear the iron wire. The portable rebar automatic wire-binding machine is small in size, ingenious in structure and simple to operate, alleviates labor intensity and greatly improves wire binding efficiency.

Description

technical field [0001] The invention relates to the technical field of electric tools and the field of engineering construction, and relates to a wire binding machine, in particular to a portable automatic steel bar binding machine. Background technique [0002] In recent years, the construction industry has developed very rapidly. From the thousand-meter-high building to the subway mine, steel frames are required for pouring. At present, the amount of steel frame used in construction is very large, and the work of binding iron wire to the steel frame is very cumbersome and hard. At present, the wire is basically tied by hand, and the speed and quality cannot be guaranteed, which has a certain impact on the progress of the construction. For the above Phenomena, domestic counterparts have developed corresponding steel wire binding machines, such as the technical scheme of the handheld electric steel wire binding machine with patent number 200710068072.X. In this technical sch...

At present, the amount of steel frame used in construction is very large, and the work of binding iron wire to the steel frame is very cumbersome and hard. At present, the wire is basically tied by hand, and the speed and quality cannot be guaranteed, which has a certain impact on the progress of the construction. For the above Phenomena, domestic counterparts have developed corresponding steel wire binding machines, such as the technical scheme of the handheld electric steel wire binding machine with patent number 200710068072.X. In this technical scheme, there is no action of tightening the iron wire, and the wire consumption is relatively large. Moreover, after the evaluation of the actual products on the market, it is found that the knotted part of the iron wire will sometimes be twisted off, and the work is not stable.
