Description

Technical Field

[0001] The utility model relates to the technical field of wire harness processing equipment, in particular to a feeding structure for a stranding machine. Background Art

[0002] Wire twisting is an indispensable process in the cable and wire industry. With the continuous development of science and the continuous progress of society, people have higher and higher requirements for wire twisting technology. Wire twisting machine, also known as high-speed wire twisting machine, is widely used in the twisting of various soft / hard conductor wires and electronic wires. A winding device that allows multiple single conductor thin wires to be intertwined to form a cable to meet the wire process requirements. It is mainly used for the twisting of power cable conductors. When the wire twisting machine is loaded, the core wire needs to be transported to the wire twisting mechanism for twisting. Nowadays, during the transportation process of the core wire, the core wire will jump along the axis direction of the wire collection wheel. When the core wire is transported to the wire twisting mechanism, the shaking of the core wire causes the instability of the wire collection wheel, which makes the tension of the core wire unstable. When the tension is too large, the core wire is tightened, resulting in the breakage of the core wire. When the tension is too small, the core wire is loose, resulting in uneven twisting, which seriously affects the working efficiency of the wire twisting machine. Utility Model Content
