An automatic steel bar binding machine

Abstract

The invention discloses an automatic rebar tying machine comprising an outer shell and a wire twisting mechanism. The wire twisting mechanism comprises a rotating rod, a chuck, a disengagement preventing mechanism, a sleeve and a spring. The rotating rod is provided with a thread section. The chuck comprises a chuck body and wire twisting claws. A spring bin is arranged at one end of the chuck body. The other end of the chuck body is hinged to the wire twisting claws. The spring is installed in the spring bin. The front end of the rotating rod stretches into the spring bin of the chuck body, is connected with the interior of the spring bin through the disengagement preventing mechanism and is connected with the spring. A conveying tooth belt is arranged on the outer surface of the sleeve and comprises a long tooth and a plurality of short teeth. The inner surface of the sleeve is provided with threads in fit connection with the thread section on the rotating rod. The rotating rod and the chuck body are connected to the interior of the sleeve respectively. The wire twisting claws are hinged to the sleeve. A lower pawl-type wide limiting piece and an upper pawl-type narrow limiting piece are arranged at the position, corresponding to the conveying tooth belt, of the outer shell. The automatic rebar tying machine is compact in structure and can feed wire and twist wire accurately.

Description

technical field [0001] The invention relates to the field of steel bar binding, in particular to an automatic steel bar binding machine. Background technique [0002] With the continuous increase of domestic labor costs in recent years, at the same time, people have more and more demands on the working environment and labor intensity, especially the high-intensity labor and difficult working environment in the construction industry. Similarly, in developed countries in Europe and the United States, companies not only have to deal with high labor costs, low work efficiency and work quality, but also have to deal with many demands such as personal dissatisfaction with work intensity. Therefore, how to realize industrial automation has become an important issue in the development of the whole society. Therefore, high-efficiency and low-strength production tools are gradually accepted by people, including automatic steel bar binding machines. Yet, because existing automatic ste...

AI Technical Summary

Problems solved by technology

[0003] 1. It is bulky and heavy, which makes it inconvenient to operate and carry;

[0004] 2. After the machine has tied the steel bars, the wires will not be stripped cleanly, which will affect the work effect and operation efficiency;

[0005] 3. The production process is complicated, the cost is high, and it is difficult to promote

[0006] Due to the above reasons, the automatic steel bar binding machine has not been promoted and popularized.
