Multi-arm yarn guide device

Abstract

The invention provides a multi-arm yarn guide device, which comprises a yarn guide box, a top pivoting device and a bottom pivoting device, wherein the yarn guide box is separated into a top concave layer and a bottom concave layer by a layer separation plate, in addition, a first layer penetrating hole and a second layer penetrating hole are arranged in the layer separation plate, the top pivoting device comprises a first gear and a second gear which are pivoted in the top concave layer and are mutually engaged, the bottom pivoting device comprises a third gear and a fourth gear which are pivoted in the bottom concave layer and are mutually engaged, the third gear and the first gear are layered and are simultaneously pivoted in the first layer penetrating hole, the fourth gear and the second gear are layered and are simultaneously pivoted in the second layer penetrating hole, the gears are respectively connected with connecting elements, in addition, the connecting elements are respectively connected with rotating arms, the rotating arms carry out simultaneous linkage through the mutually engaged gears, and in addition, the rotating arms arranged at the upper layer and the lower layer of the top concave layer and the bottom concave layer can relatively independently carry out simultaneous linkage.

Description

technical field [0001] The invention relates to a yarn guiding device of a knitting machine, in particular to a dobby yarn guiding device. Background technique [0002] Such as figure 1 As shown in , it shows a three-dimensional schematic diagram of a commonly used yarn guiding device. One side of the yarn guiding device 90 is connected with a connecting piece 91 , and a yarn guiding arm 92 is connected through the connecting piece 91 . One end of the yarn guiding arm 92 is inserted into the connecting member 91 , and the free end of the yarn guiding arm 92 is provided with two fixed upper yarn guiding eyelets 931 and lower yarn guiding eyelets 932 . [0003] The end of the yarn guide arm 92 of the commonly used yarn guide device 90 is a fixed upper yarn guide eye 931 and a lower yarn guide eye 932. The yarn eye 931 is wound around the yarn feeding wheel (not shown in the figure) once and then passes through the yarn input plate (not shown in the figure) and passes through...

AI Technical Summary

Problems solved by technology

[0006] The conventional yarn guide device 90A has two first yarn guide arms 921A and a second yarn guide arm 922A which are respectively interspersed and combined with two meshing gears. The eye 931A and the second yarn guide eye 932A are then wound around the yarn feeding wheel (not shown in the figure). Although the first yarn guide arm 921A and the second yarn guide arm 922A can swing and rotate synchronously due to gear meshing, they also It is also affected by the conveying tension when the tension of the incoming yarn and the outgoing yarn is not uniform, resulting in the severe shaking like the above-mentioned conventional single-arm yarn guide device.

In view of this, the yarn guide arm of the above-mentioned known single-arm or double-arm yarn guide device is unstable and violently shakes due to the influence of different conveying tensions of the incoming yarn and the outgoing yarn during the rapid yarn supply operation, resulting in The shaft center and shaft sleeve of the yarn device are easy to wear, which will only increase the maintenance cost, and the result of the violent shaking of the yarn guide arm will also cause knotting or breakage between the yarns. In the past knitting technology, due to the use of The yarns are all high-strength natural long fibers, nylon, polyester and other man-made fibers with high toughness, so these yarns can still withstand the unstable and severe shaking caused by the instantaneous change of the yarn conveying tension
