FIELD OF THE INVENTION
The present invention relates to rebar bundling technical field, particularly to a kind of rebar bundling machine, its replaceable gun head and working method.
BACKGROUND OF THE INVENTION
With the continuous increase of domestic labour costs in recent years, meanwhile, people's demands for working environment and labour intensity are also increasing, especially the high intensity labour and arduous working environment in the construction industry. Similarly, in developed countries in Europe and the United States, companies not only respond to higher labour costs and lower work efficiency and quality, but also to respond to individual demands such as dissatisfaction with work intensity. Therefore, how to realize industrial automation has become an important issue for the development of the whole society. Thus, high-efficiency and low-intensity production tools are gradually being accepted by people, including rebar bundling machines, which can effectively solve the low efficiency and costly issues of manual bundling.
However, there are the following disadvantages due to the existing rebar bundling machines:
- (1) The existing rebar bundling machine has a fixed gun head component after a manufacturing is completed, that is, the size of the rebar node corresponding to the gun head component is limited, the size of the rebar nodes that can be wound by a wire circle formed by the gun head component of the rebar bundling machine is also limited. And the gun head component of the rebar bundling machine is only suitable for bundling rebar nodes within a certain size range, that is, there is a requirement for the size range of the superimposed bundling rebar crossing points.
- (2) When the superimposed size of the rebar crossing point of the rebar bundling machine exceeds the use range of the gun head component, the rebar bundling machine will not work properly. However, when the superimposed size of the rebar crossing point of the rebar bundling machine is far smaller than the maximum usable range of the gun head component, it will cause problems such as poor rebar bundling, wasted wire, and unstable tightening of the machine. Especially when the superimposed size of the rebar crossing point of the rebar bundling machine is far smaller than the maximum usable range of the gun head component, the process of tightening the wire circle by the rebar bundling machine is very complicated, even if the rebar bundling machine is provided with torque adjustment; it also easily causes the machine control board to make a wrong judgment, so that the wire is too loose to tightly bundle the rebar or the wire is broken.
In this regard, the use of a single rebar bundling machine has limitations, and multiple types of rebar bundling machines are required to meet the complex rebar bundling work at construction sites. Ordinary workers can only carry a single rebar bundling machine for operation, and the rebar bundling cannot be fully covered. If multiple types of rebar bundling machines are used, it will increase the burden on workers and is not conducive to the management of tools.
Due to the above reasons, the rebar bundling machine has not been promoted and popularized. Therefore, the existing rebar bundling machine needs further improvement and innovation.
