Description

Rolling type yarn guide tensioning device

Technical Field

The invention relates to the spinning industry, in particular to a rolling type yarn guide tensioning device.

Background

Because the fabrics woven by the warp knitting machine have different patterns, different raw materials, different starting speeds and the like, and the required warp feeding amount of the yarns is also different, the tension control of the warp knitting machine is an important link in the weaving process. During the weaving process of the warp knitting machine, the yarns are fed into the warp knitting machine for weaving, and the tension on the yarns is continuously changed during the weaving process of the fabric, so that yarn breakage is easily caused due to unstable tension.

Disclosure of Invention

The invention provides a rolling type yarn guide tensioning device which can reduce yarn breakage, provide a certain pre-tensioning force, ensure the tension of yarn and ensure the spinning quality.

The invention provides the following technical scheme: the rolling type yarn guiding and tensioning device comprises a main frame 1 and is characterized by further comprising a first rolling column 2, a second rolling column 3, a yarn guiding rod 4, a yarn guiding plate 5, a stabilizing frame 6 and a stabilizing rod 7, one end of the stabilizer bar 7 is fixedly connected with the main frame 1, the other end of the stabilizer bar 7 is fixedly connected with the stabilizer 6, one end of the first rolling column 2 and one end of the second rolling column 3 are movably connected with the main frame 1, the other end of the first rolling column 2 and the other end of the second rolling column 3 are movably connected with the stabilizing frame 6, the yarn guide rod 4 and the yarn guide plate 5 are both provided with through holes which are distributed linearly, yarns 8 sequentially penetrate through the yarn guide rod 4, cross the first rolling column 2 and the second rolling column 3 in a winding manner, penetrate through the yarn guide plate 5 and extend downwards around the wall of a ball which crosses the first rolling column 2; the rolling type yarn guide tensioning device further comprises a tensioning mechanism, the tensioning mechanism comprises a spring plate 13, a tensioning screw 9, a spring 10 and a swing arm 11, the spring plate 8 is fixedly connected with the main frame 1, the swing arm 11 is movably connected with the spring plate 8, a yarn threading ring 12 is arranged at one end of the swing arm 11, the yarn 8 between the first rolling column 2 and the second rolling column 3 penetrates through the center of the yarn threading ring 12, the other end of the swing arm 11 is fixedly connected with one end, close to the tensioning screw 9, of the spring plate 13, the tensioning screw 9 penetrates through the spring 10, a nut 14 is screwed at the other end of the tensioning screw 9, and the spring 10 is arranged between the nut 14 and the spring plate 13.

The invention has the beneficial effects that: the device can be screwed with the nut 14 to adjust tension, the nut 14 is rotated, the swing arm 11 is pulled by the tension screw 9, the swing arm 11 drives the yarn threading ring 12 to move downwards, and then the amplitude of the yarn pulled by the yarn threading ring 12 is controlled, so that the tension of the yarn is adjusted and controlled. The yarn threading ring 12 pulls the yarn along the yarn trend, provides a certain pretension force for the yarn, is beneficial to spinning operation and ensures the spinning quality.
