Description

Technical Field

[0001] The utility model belongs to the technical field of wire mesh weaving, and in particular relates to a conveying device of a wire mesh weaving machine with a wire breakage stop function. Background Art

[0002] A wire mesh weaving machine is a device used to manufacture a variety of wire mesh products. It typically utilizes shuttleless linear weft insertion technology, with automatic warp delivery and take-up via a conveyor system to achieve continuous weaving of the wire mesh. During the weaving process, the machine automatically adjusts the tension of the warp and weft threads according to preset parameters and texture requirements to ensure the smoothness and uniformity of the mesh surface.

[0003] In the prior art, warp wires may break during the operation of a wire mesh weaving machine. A method for detecting warp wire breakage is usually to horizontally connect a metal wire above each transmission roller of a transmission device, and then energize the warp wires and the metal wires. When the warp wires break, the tension of the warp wires causes the warp wires to contact the metal wires, causing a short circuit in the wire mesh weaving machine, thereby achieving a shutdown effect. However, when the wire mesh weaving machine is inspected and maintained, the metal wires horizontally connected above the transmission device will affect the inspection and maintenance of the staff, resulting in poor adaptability and poor practicality.
