Description

Technical Field

After searching, it was found that the Chinese patent with the announcement number CN220887870U disclosed a weaving tension adjustment device. In this patent, the support frame is installed at a specific position of the loom, the connecting base is fixed to the support structure of the loom through a card interface, and the adjusting bolt is fixed to the support plate through a threaded installation. The wire wheel frame is installed on the support plate, and the first wire wheel on the wire wheel frame is used to guide the textile line. The textile line passes through the second wire wheel. When the tension of the textile line is too loose, the second fixing bolt is screwed to make the second fixing bolt push the extension column to rotate the extension column in the vertical direction.
