[0002] During the wire mesh weaving process, especially for places such as coal mines and mining that have high requirements for wire mesh, the nodes of the wire mesh need to be wrapped 2 to 3 times. The wire mesh has a hexagonal frame structure, which can prevent external forces from causing the steel wires wrapped at the nodes of the wire mesh to slide against each other.

[0003] In order to realize the above-mentioned wire mesh weaving, it is necessary to realize the dislocation movement between adjacent steel wires and make the adjacent steel wires entangled for 2 to 3 weeks. Under the complex weaving steps, high precision requirements and steel wire thickness requirements, the wire mesh weaving in the current technology requires the cooperation of multiple power output devices. On the one hand, it causes more equipment operation cooperation requirements, and on the other hand, when one of the power output devices fails to operate in place, it may cause equipment damage. In addition, multiple power output devices also increase the cost of the wire mesh weaving machine. Utility Model Content
