[0002] The single-sided knitting machine is a common type of circular knitting machine. During the production process of the single-sided knitting machine, due to the raw materials used, fabric requirements and other reasons, the single-sided knitting machine needs to be fine-tuned frequently, such as adjusting the relative position of the sinker throat trajectory and the knitting needle head trajectory, that is, adjusting the relative position of the sinker triangle and the knitting needle triangle, which is commonly known as adjusting the food position in the industry.

[0003] The traditional adjustment method is generally to adjust the sinker triangle, refer to Figure 1 Figure 2 As shown, the sinker triangle is installed on the upper disc seat, and the upper disc seat is installed on the seven-shaped foot. Loosen the bolts between the upper disc seat and the seven-shaped foot, and adjust the circumferential position of the upper disc seat of the structure, thereby adjusting the circumferential position of the sinker triangle relative to the needle triangle. This traditional adjustment method has a defect. When adjusting the axial position of the upper disc seat, the center of the upper disc seat will inevitably shift relative to the center of the needle cylinder. This shift will cause the sinker triangle to shift laterally, that is, the in and out movement of the sinker will change. Although this offset is small, it is enough to be reflected on the cloth surface when producing sensitive materials, resulting in a decrease in the quality of the cloth surface.

DETAILED DESCRIPTION

[0024] The present invention is further described below through specific implementation modes.

[0025] Reference Figure 1 , Figure 3-Figure 5 As shown, a single-sided knitting machine includes a large plate 1, a saddle bottom ring 2, a needle triangle 3, a stopper 4, a positioning block 5, a limiting block 6, a seven-shaped foot 7, an upper plate seat 8, and a sinker triangle 9.

[0026] The sinker triangle 9 is used to drive the sinker to move forward and backward horizontally. The sinker triangle 9 is arranged on the upper plate seat 8, and the upper plate seat 8 is arranged on a plurality of seven-shaped feet 7, and each seven-shaped foot 7 is arranged on the large plate 1.

[0027] The knitting needle triangle 3 is arranged on the saddle bottom ring 2, and the saddle bottom ring 2 is placed on the large plate. The saddle bottom ring 2 is provided with an elongated hole 21, and a locking screw 22 is provided in the elongated hole 21 for locking and positioning the saddle bottom ring 2 and the large plate 1. The stopper 4 is protrudingly arranged on the side of the saddle bottom ring 2, and specifically, a threaded hole 23 is provided on the side wall of the saddle bottom ring 2. The stopper 4 is provided with a screw 41, and the stopper 4 is connected to the saddle bottom ring 2 by screwing the screw 41 into the threaded hole 23. The alignment block 5 is fixedly arranged on the large plate 1, and the alignment block 5 is provided with two groups, which are respectively located on both sides of the stopper 4, and the two groups of alignment blocks 5 are respectively provided with adjustable top screws 51, and the ends of the two groups of adjustable top screws 51 respectively press against the stopper 4 from both sides. The alignment block 5 includes a transverse portion 52 and a longitudinal portion 53. The transverse portion 52 is fixed to the large plate 1 by a bolt structure. The longitudinal portion 53 is provided with a transversely extending through screw hole 531. The adjustable top screw 51 is arranged in the through screw hole 531 by a threaded structure.

[0028] The limit blocks 6 are fixed on the large plate 1. The limit blocks 6 are provided with a plurality of blocks, each of which is distributed around the periphery of the saddle bottom ring 2 and close to the side wall of the saddle bottom ring 2. The limit blocks 6 are provided with at least three groups, each of which is distributed circumferentially around the axis of the large plate 1.

[0029] The working principle of this single-sided machine is as follows:

[0030] In actual production, the relative position of the sinker cam 9 to the knitting needle cam 3 needs to be adjusted to adjust the feeding position according to the raw materials used, the requirements of the fabric surface, etc. In the debugging method adopted in the present invention, the sinker cam 9 remains stationary, and the knitting needle cam 3 is adjusted to adjust the feeding position. The position of the upper disc seat and the sinker cam 9 arranged on the upper disc seat is kept unchanged, and the position of the needle cylinder is kept unchanged, that is, the upper disc seat and the needle cylinder are kept in a coaxial state.

[0031] The locking screws 22 of the saddle bottom circle 2 are loosened to make the saddle bottom circle 2 and the large plate 1 adjustable, and the two adjustable top screws 51 of the positioning blocks 5 on both sides are rotated to adjust. The adjustable top screw 51 on one side retracts to form a clearance space, and the adjustable top screw 51 on the other side extends out, and the end thereof abuts against the stopper 4 and pushes the saddle bottom circle 2 to rotate, so as to change the relative position of the track of the knitting needle cam 3 and the track of the sinker cam 9, so that the saddle bottom circle 2 is rotated circumferentially to the desired position; the adjustable top screws 51 on both sides are adjusted again, and the position of the saddle bottom circle 2 is kept unchanged, so that the ends of the two adjustable top screws 51 abut against the stopper 4 from the opposite sides to form a clamping and positioning state; and then the locking screws 22 are tightened again to position the saddle bottom circle 2 and the large plate 1, and the food position is adjusted.

[0032] In the above process, due to the obstruction of the limit blocks 6, the saddle bottom ring 2 is restricted from rotating around the central axis, but there will still be an inevitable central axis offset. This offset changes the gap between the needle triangle 3 and the needle cylinder. Since the offset is very small, the change in the gap will not affect the movement of the needle butt in the track of the needle. The movement track of the needle is up and down, while the gap changes to left and right. Therefore, the track of the needle will not be affected, and the needle is accurately raised and lowered. Therefore, this method can be used to complete the feeding position adjustment action, and since the position of the upper disc seat 8 is not changed, the center of the upper disc seat 8 will not be offset relative to the center of the needle cylinder, and the position of the sinker moving forward and backward is accurate, which will not affect the quality of the cloth.

[0033] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
