Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-6, a warp yarn tension adjusting structure comprises a yarn passing roller 1 and a press roller 2 arranged opposite to the yarn passing roller 1, wherein the press roller 2 presses warp yarns against the yarn passing roller 1, a gap for the warp yarns to pass through is formed between the press roller 2 and the yarn passing roller 1, and the warp yarns are flattened and tensioned after passing through the gap and are continuously conducted through the yarn passing roller 1; the surface of the compression roller 2 is provided with an elastic layer; the press roller 2 is configured as a rubber roller; at least one of the press roller 2 and the yarn passing roller 1 is movably opened and closed; the wire passing roller 1 is configured as a driving roller or a driven roller; the press roller 2 and/or the wire passing roller 1 are/is configured to be capable of moving close to or far away from each other; the press roll 2 is an integrally arranged roll or a sectionally arranged roll, and correspondingly, the wire passing roll 1 is an integrally arranged roll or a sectionally arranged roll; the press rollers 2 and the corresponding wire passing rollers 1 are provided with a plurality of groups which are arranged in a staggered manner.
