The invention discloses a flocculent-
yarn blowing and heat dissipation improved structure for a circular knitting
machine. The improved structure mainly includes a
machine table, fixing assemblies, ahydrargyrum base, a monitoring device and a flocculent-
yarn blowing and heat dissipation structure body; the symmetrical fixing assembles are fixedly inserted into the outer edge of an upper needle hole of the
machine table, the hydrargyrum base is clamped at the position close to the center of the upper needle hole, the monitoring device is arranged above the hydrargyrum base, a first lamp is fixedly assembled on the inner side of a first side edge of one side of a supporting frame of the monitoring device, and the flocculent-
yarn blowing and heat dissipation structure body is locked and combined, towards the top surface, with a second side edge of the other side of the supporting frame. By blowing away flocculent yarn to prevent yarn from piling up to form
cotton balls, a yarn needle isnot easily entangled, and increasing of the defect rate of the cloth is reduced; meanwhile, by monitoring outage through a checking light, knitting signals when the yarn is knitted are controlled so that
noise cannot be generated, and thus it is further achieved that a power supply is not subjected to abnormal
efficacy; therefore, the tension is adjusted, and meanwhile the thickness of the cloth is adjusted to be suitable for the tightness of rolling, so that the flocculent-yarn blowing and heat dissipation improved structure for the circular knitting machine is formed.
