[0002] In the development of the textile industry, in order to make fabrics better and more labor-saving, various textile machines have been researched and manufactured. Among them, flat knitting machines are widely used in the textile industry. A flat knitting machine is an advanced knitting machine that can achieve various complex patterns and designs through computer control.

[0003] However, in the existing flat knitting machines during the knitting process, there is a process of needle turning. But during the needle turning process, when the knitting needles are lifted, it is easy for the knitting needles to lift the fabric that has been knitted below, and the knitting needles on the opposite side will hook the knitted fabric, which will lead to the appearance of defective products. This phenomenon is also called floating pieces. Summary of the Utility Model

[0004] The present application provides an auxiliary component for a flat knitting machine, which can solve the problem that when the knitting needles are lifted during the needle turning process of the flat knitting machine, the fabric that has been knitted below the knitting needles is easily lifted. Through the cooperation of the sinker and the tooth piece, the knitted coils can be effectively pressed, and the floating piece problem can be solved.

[0005] In the present application, an auxiliary component for a flat knitting machine is provided, including a steel wire. The steel wire is installed on the flat knitting machine, and an auxiliary component is installed on the steel wire. The auxiliary component includes a sinker and a tooth piece. A hook-shaped portion is provided on the sinker. The hook-shaped portion sequentially includes an inclined surface 1, a semi-circular surface 1, an inclined surface 2, an arc surface 1, a vertical surface, and an arc surface 2. A pressing portion is provided on the tooth piece. The pressing portion sequentially includes an inclined surface 3, an arc surface 3, an arc surface 4, an inclined surface 4, an arc surface 5, an arc surface 6, and an inclined surface 5.

[0006] Further, the vertical distance between the uppermost end of the inclined surface 1 and the lowermost end of the arc surface 2 is 6 mm - 6.5 mm, and the horizontal distance between the rightmost end of the inclined surface 1 and the rightmost end of the arc surface 2 is 5 mm - 5.5 mm.

Detailed Embodiments

[0018] The following are only the preferred embodiments of the present utility model, and the protection scope is not limited to this embodiment. All technical solutions falling within the concept of the present utility model shall belong to the protection scope of the present utility model. At the same time, it should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements should also be regarded as the protection scope of the present utility model.

[0019] As shown Figure 1 in the figure, an auxiliary component for a flat knitting machine includes a steel wire 1. The steel wire 1 is installed on the flat knitting machine, and an auxiliary component 2 is installed on the steel wire 1. The auxiliary component 2 includes a sinker 201 and a tooth piece 202. An installation hole 6 is provided on the sinker 201, and an installation hole 7 is provided on the tooth piece 202. The installation hole 6 and the installation hole 7 are used for the installation of the steel wire 1.

[0020] As shown Figure 2 and Figure 4 in the figure, a hook portion 3 is provided on the sinker 201. The hook portion 3 successively includes an inclined surface 301, a semi-circular surface 302, an inclined surface 303, a circular arc surface 304, a vertical surface 305, and a circular arc surface 306. The upper end of the inclined surface 301 is tangent to the sinker 201, the lower end of the inclined surface 301 is tangent to the upper end of the semi-circular surface 302, the right end of the semi-circular surface 302 is connected to the left end of the inclined surface 303, the right end of the inclined surface 303 is connected to the right end of the circular arc surface 304, the left end of the circular arc surface 306 is tangent to the upper end of the vertical surface 305, the lower end of the vertical surface 305 is tangent to the upper end of the circular arc surface 306, and the left end of the circular arc surface 306 is tangent to the sinker 201. When the flat knitting machine drives the sinker 201 to press down during needle turning, the sinker 201 presses the knitted fabric through the hook portion 3. The inclined surface 301 can quickly slide the fabric into the circular arc surface 304, and the vertical surface 305 plays a role of blocking and limiting, ensuring that the fabric is stable in the circular arc surface 304. If the fabric deviates outward from the inclined surface 301, the semi-circular surface 302 can play a role of blocking and limiting. In this way, the flat knitting machine can press the knitted fabric during needle turning, ensuring that the opposite knitting needle will not hook the knitted fabric.

[0021] Further, the vertical distance between the uppermost end of the inclined surface 301 and the lowermost end of the circular arc surface 306 is 6 mm - 6.5 mm, and the horizontal distance between the rightmost end of the inclined surface 301 and the rightmost end of the circular arc surface 306 is 5 mm - 5.5 mm.

[0022] Further, the radius of the semi-circular surface is R0.1 - R0.2, and the included angle between the inclined surface 301 and the vertical surface 305 with the vertical surface 305 as the reference is 65° - 70°.

[0023] As shown Figures 3 to 5As shown, a pressing part 4 is provided on the tooth mouth piece 202. The pressing part 4 successively includes an inclined surface three 401, an arc surface three 402, an arc surface four 403, an inclined surface four 404, an arc surface five 405, an arc surface six 406 and an inclined surface five 407. The upper end of the inclined surface three 401 is connected to the tooth mouth piece 202. The lower end of the inclined surface three 401 is tangent to the upper end of the arc surface three 402. The lower end of the arc surface three 402 is tangent to the upper end of the arc surface four 403. The lower end of the arc surface four 403 is tangent to the upper end of the inclined surface four 404. The lower end of the inclined surface four 404 is tangent to the upper end of the arc surface five 405. The lower end of the arc surface five 405 is tangent to the upper end of the arc surface six 406. The lower end of the arc surface six 406 is tangent to the upper end of the inclined surface five 407. The lower end of the inclined surface five 407 is connected to the tooth mouth piece 202. The pressing part 4 of the tooth mouth piece 202 cooperates with the hook part 3 on the sinker 201, and can further press the woven fabric. When the hook part 3 of the sinker 201 presses down the fabric, the fabric will slide in from the inclined surface three 401 at the same time and then pass through the arc surface three 402 and the arc surface four 403, and then pass through the inclined surface four 404, and finally be pressed by the arc surface five 405 and the arc surface six 406. When turning the needles, the woven fabric is pressed at the arc surface five 405 and the arc surface six 406. The inclination of the inclined surface three 401 makes the arc surface three 402 and the arc surface four 403 form a limiting step. If the fabric slides out from the inclined surface four 404, then the fabric will be limited by the arc surface three 402 and the arc surface four 403, achieving a double protection. Without external pulling force, through the cooperation of the tooth mouth piece 202 and the sinker 201, the already woven coils can be effectively pressed, effectively solving the problem of floating pieces.

[0024] Further, the vertical distance between the uppermost end of the inclined surface three 401 and the lowermost end of the inclined surface five 407 is 8 mm - 8.5 mm, and the horizontal distance between the rightmost end of the arc surface three 402 and the leftmost end of the inclined surface five 407 is 6 mm - 7 mm

[0025] Further, a through hole 5 is provided on the tooth mouth piece 202. The through hole 5 can be used to pass through the steel wire 1, and the installation position of the tooth mouth piece 202 can be adjusted through the through hole 5.
