[0002] Flax is a natural cellulose plant fiber. With its beautiful texture and good air permeability, it has become one of the favorite textile raw materials for many people. And flax roving is a rough yarn obtained after processing flax fibers, which has great differences from fine yarn in terms of technology and use.

[0003] In the production process of flax roving, the boiling and bleaching process is an indispensable link.

[0043] A plurality of groups of support rods 502 are symmetrically arranged on the inner side of the hanger 501, so that the flax roving can be connected to the outer surface of the support rods 502 and stretched out, thereby increasing the contact area between the flax roving and the bleaching solution. When the connecting frame 404 rotates along with the rotation of the rotating shaft 403, the hanger 501 fixedly installed on the inner side thereof can be driven to rotate. When the hanger 501 rotates, the support rods 502 fixedly installed on the inner side thereof can be driven to rotate. When the support rods 502 rotate, the flax roving connected to the surface thereof can be driven to rotate, thereby driving the roving to contact the bleaching solution evenly and quickly.

[0044] In one embodiment, for the above-mentioned limiting assembly 6, the limiting assembly 6 includes two groups of sliding grooves 601, both of which are opened on one side of the hanger 501, and the insides of the two groups of sliding grooves 601 are opened with a card slot 602, and the inside of one group of the sliding grooves 601 is opened with a moving groove 603, and the inside of the moving groove 603 is slidably provided with a moving column 604;

[0046] By pulling the limit frame 605, the movable column 604 fixedly connected to one side thereof can be driven to move inside the movable groove 603. When the movable column 604 moves to one side of the movable groove 603, the movable column 604 can be driven to rotate inside the movable groove 603 by rotating the limit frame 605, so that the limit frame 605 can perform a circular motion with the movable column 604 as the center, and then rotate it to be parallel to the inner side of one group of sliding grooves 601, and push the limit frame 605 to enable it to move inside the sliding groove 601, and then enable it to clamp the limit frame 605 to avoid rotating downward, so that one side of the hanging bracket 501 can be opened, which is convenient for wrapping the flax roving around the outer surface of the support rod 502 for installation, which is more convenient.

[0047] In one embodiment, for the above-mentioned limiting assembly 6, the limiting assembly 6 further includes a positioning rod 607, one end of which is fixedly connected to the inside of the limiting frame 605, and a push rod 608 is slidably provided on the outer surface of the positioning rod 607, and one end of the push rod 608 is fixedly connected to the bottom end of the block 606;
