Description

Technical Field

[0001] The utility model relates to the field of circular knitting machines, in particular to a yarn guiding device of a double-sided circular knitting machine. Background Art

[0002] Double-sided circular knitting machine, scientifically known as circular weft knitting machine, has developed rapidly due to its multiple loop forming systems (referred to as yarn feeding paths or loop forming paths in enterprises, referred to as paths), high speed, high output, fast shape change, good fabric quality, few processes, and strong product adaptability.

[0003] Most of the existing yarn guiding devices of double-sided circular knitting machines do not have the function of detecting and adjusting the tension of the yarn during the yarn guiding process. When the tension of the yarn is high, it is very easy to cause the yarn to break. When the tension of the yarn is low, it is very easy for the yarn to be twisted and entangled, which is inconvenient for the staff to use. For this reason, we propose a yarn guiding device for a double-sided circular knitting machine. Utility Model Content

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the utility model provides a yarn guide device for a double-sided circular knitting machine, which has the following beneficial effects:

[0016] When adjusting the tension of the yarn of the double-sided knitting large circular machine, the yarn is first installed on the first yarn drum and the second yarn drum, and the yarn can be guided by the set guide wheel. The tension of the yarn can be detected by the set three-pulley tension sensor. At this time, the three-pulley tension sensor transmits the tension data to the control center. When the tension of the yarn is loose, the control center will start the motor, and the rotating shaft and the first gear will rotate, driving the second gear and the threaded sleeve to rotate, and the threaded rod, the shell and the pressure wheel connected by the thread will move. At this time, the pressure wheel contacts the yarn, and the yarn can be pressed downward, thereby increasing the tension. Through the above structure, it is convenient for the staff to adjust the tension of the yarn of the double-sided knitting large circular machine, and the tension of the yarn can be automatically detected and adjusted. The degree of automation is high, and there is no need for manual adjustment by the staff, which reduces the unnecessary workload of the staff and greatly facilitates the use of the staff.
