Description

Technical Field

[0001] The utility model relates to the field of yarn processing, in particular to a yarn extrusion flattening device. Background Art

[0002] Yarn is a textile product that is processed into a certain fineness using various textile fibers and is used for weaving, rope making, thread making, knitting and embroidery, etc. Yarn is classified according to raw materials, including pure spun yarn and blended yarn. Pure spun yarn is yarn spun from one fiber material, and blended yarn is yarn spun from two or more fibers. Blended yarn is more practical in daily life because blended yarn has the excellent material properties of multiple yarns. The yarn is in a plush state before spinning and needs to be squeezed and flattened to facilitate winding and subsequent spinning work. For this reason, a yarn squeezing and flattening device is proposed;

[0003] To solve the above problems, after searching, a Chinese patent with the authorization announcement number CN208501191U discloses a yarn squeezing and flattening device; the invention includes that as the second yarn roller rotates and generates heat, the yarn passing through the second yarn roller sleeve and the third yarn roller is squeezed and flattened by the two, and the fourth roller shaft is driven to rotate by the second motor, thereby driving the fourth yarn roller to rotate, and the squeezed and flattened yarn is wound up;

[0004] In actual use, the yarn is thinner and the second yarn roller sleeve is longer. The heat generated by the second yarn roller sleeve is only used for heating the position in contact with the yarn, while the heat generated at other positions of the second yarn roller sleeve is wasted, consuming a lot of energy and is not practical.
