Description

Technical Field

[0001] The utility model belongs to the technical field of wire mesh weaving, and in particular relates to an adjustable warp breakage detection device for a loom. Background Art

[0002] A wire mesh weaving machine is a type of equipment used in the wire mesh weaving industry, primarily for producing various types of wire mesh, such as open mesh and dense mesh. During the weaving process, the machine automatically adjusts the tension of the warp and weft threads according to preset parameters and pattern requirements to ensure the smoothness and uniformity of the mesh surface. The warp threads are wound around a warp beam, which then unwinds and is transported via conveyor rollers.

[0003] In the prior art, warp wires may break during the operation of the wire mesh weaving machine, and a method for detecting warp wire breakage is usually to horizontally connect a detection wire above each transmission roller of the transmission equipment, and then energize the warp wires and the detection wire. When the warp wires break, the tension of the warp wires causes the warp wires to contact the detection wires, causing a short circuit in the wire mesh weaving machine, thereby achieving a shutdown effect. However, a wire threading process is required before the wire mesh weaving machine works. During the wire threading process, since the detection wire is horizontally connected above each transmission roller of the transmission equipment and is close to the transmission rollers, the wire threading process is prone to interference with the detection wire. The wire threading process is time-consuming and labor-intensive, and has poor adaptability and practicality. Utility Model Content
