For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0026] Referring to Figures 1 to 4 The knitting track adjusting device of the knitting machine shown in the figure comprises a track body 1 and an adjusting component 2 installed at the bottom of the track body 1, the angle and height of the track body 1 are adjusted through the adjusting component 2, the top of the track body 1 is provided with a wire slot 101, the wire slot 101 penetrates the track body 1 radially, two wire guides 3 are symmetrically arranged at the wire inlet position of the wire slot 101, a knitting wire 4 passes through the wire slot 101 and is limited between the two wire guides 3, and the spacing between the two wire guides 3 is less than the slot width of the wire slot 101.

[0027] In the above technical solution, the two wire guides 3 can guide the position of the knitting wire 4, reduce the contact between the knitting wire 4 and the opening of the wire slot 101, and reduce the wire abrasion.

[0028] By adjusting component 2, the angle and height of track body 1 can be reasonably adjusted according to the position of the weaving assembly of the knitting machine.

[0029] See Figure 1 and Figure 3 As shown, the adjusting component 2 includes a base 21, a bracket 22, a movable plate 23, an adjusting bolt 24, and a guide rod 25. The two ends of the base 21 are bent downward to form a clamp 210. The bracket 22 is fixed to the top of the base 21. A bearing 26 is fitted between the adjusting bolt 24 and the bracket 22. The guide rod 25 passes through the bracket 22 and moves vertically along the bracket 22. The bottom of the movable plate 23 is fixed to the guide rod 25. A threaded hole is machined at the axis of the movable plate 23, and the threaded hole fits the adjusting bolt 24. A recessed hole 121 is machined at the bottom of the track body 1, and the movable plate 23 is embedded in the recessed hole 121. A first bearing 131 is fitted between the movable plate 23 and the recessed hole 121. A locking screw 141 is screwed into the outside of the track body 1. The locking screw 141 abuts against the movable plate 23, and the track body 1 is locked at this time.

[0030] In the above technical solution, the height of the movable plate 23 is adjusted by rotating the adjusting bolt 24. With the support of the first bearing 131, the track body 1 can be rotated. After rotating to the required angle, the position is locked by the locking screw 141.

[0031] See Figure 2 As shown, the arc transition at the outlet position of the wire groove 101 forms a curved surface portion 133.

[0032] The function of the curved surface 133 is to reduce wire wear at the outlet when there is a deviation between the inlet and outlet angles.

[0033] See Figure 3 As shown, the groove 101 has an arc-shaped, upward-convex groove bottom structure 134.

[0034] The use of an arc-shaped, convex groove bottom structure 134 allows stray hairs that fall into the groove 101 to be smoothly carried out.

[0035] See Figure 1 and Figure 3As shown, the wire guide 3 comprises a mounting plate 31 fixed at the wire inlet position of the wire slot 101, a fixed shaft 32 fixed with the mounting plate 31, and a wire cylinder 33 cooperating with the fixed shaft 32 through a second bearing. The wire cylinder 33 is tapered, with its diameter gradually decreasing downward, and the outer walls of the two wire cylinders 33 form an "A"-shaped wire passing opening 333. The knitting wire is limited in the wire passing opening 333, and the bottom end width of the wire passing opening 333 is smaller than the slot width of the wire slot 101.

[0036] In the above technical solution, the knitting wire 4 is limited by the wire passing opening 333, so that the knitting wire 4 is always limited on the inner side of the wire passing opening, avoiding the knitting wire from being separated from the wire slot 101 when the wire is jumped.
