Description

Technical Field

[0001] The utility model relates to the technical field of yarn guide devices of a spinning frame, in particular to a yarn guide device of a spinning frame. Background Art

[0002] Spinning frame is a spinning machine that draws, twists and winds semi-finished roving or sliver into spun yarn during the spinning process. Specifically, the sliver is drawn and twisted on the roving frame to make roving, the roving is drawn and twisted on the spinning frame to make spun yarn, the sliver is drawn and twisted on the roving frame to make roving, the combing machine combs the fibers to make combed slivers, the pinning machine combines the slivers, the pin row drafting improves the sliver structure, and the roving is further twisted and spun into spun yarn on the ring spinning frame.

[0003] The Chinese patent with the prior art authorization announcement number CN215800131U discloses a yarn guide device for a spinning machine that prevents hanging flowers. The threaded rod is rotated to drive the movable block to move upward. During the upward movement, the movable block will drive the rubber pad inside the second groove to separate from the outer end of the yarn guide rod, so that the contact arc plate and the movable block no longer clamp the yarn guide rod. At this time, the connecting sleeve block can move along the yarn guide rod. After determining the position of the adaptive mechanism, the reverse operation can be performed to move the movable block downward to cooperate with the arc plate to clamp the yarn guide rod, so that the fixing mechanism cannot move at the outer end of the yarn guide rod, thereby fixing the position of the adaptive mechanism on the yarn guide rod. The fixing mechanism can fix the adaptive mechanism quickly and easily, and is very convenient to use.

[0004] Although the above patent enables the connecting sleeve to be moved along the yarn guide rod, the threaded rod needs to be rotated each time the connecting sleeve is moved, and after it is moved into place, a reverse operation is required to fix it. If there are many connecting sleeves to be moved, the operation will be more troublesome, which increases the labor intensity of the staff and reduces work efficiency. Moreover, the device cannot properly adjust the tightness of the yarn during transportation, resulting in the yarn and the equipment being entangled together, reducing work efficiency.
