A tension cover assembly of a yarn tensioner on a two-for-one twister comprises two opposite tension covers, wherein each tension cover comprises an annular cover disc, and an annular outer flange is formed on the outer ring of each cover disc; an annular rib groove which is sunken inwards is formed in the cover disc close to the inner ring of the cover disc, a check ring which is sunken inwards is formed on the bottom surface of the annular rib groove, and a guide slot which is communicated with the annular rib groove and is in an annular shape is formed in the check ring; the annular rib grooves of the two tension covers are spliced with tension rings with arc-shaped sections, the outer rings at the two ends of each tension ring are bent to form annular guide sleeves, and the guide sleeves at the two ends of each tension ring are inserted into the guide slots of the two tension covers respectively.
Preferably, the central axis of the tension ring, the central axis of the cover disc and the central axis of the retainer ring are all on the same straight line.
Preferably, the width of the retainer ring on the cover plate is smaller than that of the outer retainer ring.
Preferably, the diameter of the inner wall of the tension ring is larger than the distance between the two tension cover upper cover discs.
Preferably, the groove width of the guide slot on the tension cover retaining ring is larger than the wall thickness of the guide sleeve on the tension ring.
Preferably, the inner walls of the two sides of the annular rib groove are conical surfaces, and the edge at the large-diameter end of each conical surface is provided with a radius; and a circular arc-shaped transition sleeve is formed between the outer ring of the tension ring and the guide sleeve.
The beneficial effects of the utility model reside in that:
the tension cover assembly is optimized and improved, the tension ring is adopted to prevent the yarn from contacting with the screw on the tensioner, and the edge of the tension ring is hidden in the tension cover, so that the abrasion of the yarn can be effectively avoided.
