Description

Technical Field

[0001] The utility model relates to the field of wire harness processing equipment, in particular to a semi-automatic tape wrapping machine for double wire harnesses. Background Art

[0002] A double harness, a pair of insulated wires twisted together, is widely used in automotive wiring harnesses. To prevent interference between the two harnesses, tape is often used to partially secure them. Traditional tape wrapping relies heavily on manual labor, which is inefficient and prone to errors.

[0003] Existing wire harness taping devices are mainly used for taping single wire harnesses, and are not very effective for dual wire harnesses, especially dual wire harnesses with inconsistent lengths. Existing wire harness taping devices are not very effective in fixing them, and during operation, one wire harness may slip off, or the longer wire may interfere with the tape wrapping. For example, patent CN220569473U uses two clamps to fix the wire harness that needs to be taped, so that the wire harness remains taut, which is more suitable for taping single wire harnesses. Patent CN219497424U clamps and fixes one end of the wire harness with a clamping assembly, and the other side of the wire harness passes through the support assembly of the winding mechanism. By rotating the double helical screw, the limit seats are relatively close to limit the wire harness, which is also more suitable for taping single wire harnesses. Utility Model Content
