[0002] The large cam circular loom is a mechanical device used for weaving fabrics. It uses the movement of a large cam to drive the heald rod, which drives the fabric on the loom through its ups and downs. The ups and downs of the heald rod push the yarn on the loom in an interlaced manner for weaving.

[0003] In the related art, the large cam is set to an annular curve so that the roller on the heald rod moves along the curved annular cam. For example, the patent with the prior art publication number CN209178581U provides a transmission mechanism of the large cam and the heald rod lifting and lowering assembly of a circular loom. The device arranges an outwardly protruding guide rail on the large cam, which cooperates with a pair of running wheels on the guide device, so that the mechanism transmission has smaller friction and the transmission is more stable and reliable.

[0004] Although the above-mentioned prior art solution can achieve the effect of stable up and down fluctuation of the heald rod through the setting of the large cam and the roller, it still has the following defects: the fluctuation height of the heald rod is determined by the height of the large cam, and its height cannot be freely adjusted, which limits the movement range of the heald rod, cannot adapt to different weaving threads for weaving, and also affects the quality of weaving.

[0005] In view of this, we propose a large cam circular loom transmission mechanism. Utility Model Content
