Description

Technical Field

[0001] The utility model relates to the technical field of metal wire winding equipment, in particular to a full-automatic wire winding machine. Background Art

[0002] In the prior art, especially in the process of making gabion mesh, in order to facilitate the supply of metal wire, a reed tube is generally used. The reed tube contains a spring wire. The spring wire is the metal wire wound in a spiral form into a long rod. The temporary storage and feeding of the metal wire is completed by the spring wire.

[0003] Spring wire can be made by a wire winding machine. Through the wire winding machine, the metal wire is gradually wound onto a core shaft to form the spring wire. In the process of winding the spring wire, the larger the gap between each turn of the metal wire, the shorter the length of the metal wire stored in the spring wire as a whole. At the same time, the lower the tightness of the spring wire, the more unfavorable the multi-layer winding of the spring wire is, and the overall quality of the spring wire is reduced. Therefore, it is necessary to improve and upgrade the existing technology, increase the length of the metal wire stored in the spring wire, and improve the winding quality of the spring wire.
