In one embodiment, as shown in fig. 1, a double-sided circular weft knitting machine comprises a weft knitting machine body and a sinker cam 100 for a cylinder knitting structure on the weft knitting machine body, wherein the sinker cam 100 comprises a needle returning part 110 and a corner part 120 with a downward opening, which are arranged in a plane, and the needle returning part 110 and the corner part 120 are connected through an arc-shaped connecting part 130 with an upward opening.
In the embodiment, the needle returning part 110 can accommodate 6 knitting needles, and the height of the needle returning part 110 is 0.8 mm. The front section needle pressing angle of the arc-shaped connecting part 130 is 52.5 degrees, and the rear section needle lifting angle of the arc-shaped connecting part 130 is 52 degrees.
In the above-described double-sided circular weft knitting machine, the improved sinker cam 100 (left side of the drawing) has a backstitch height of 1.1 mm, which is higher than 1000.3 mm of the improved sinker cam 100, as compared with the conventional sinker cam 100 (right side of the drawing). The maximum stroke of a knitting needle of the improved sinker cam 100 is 11.6 cm, and the length of a loop is 15-23 mm/100.
For example, the high-grade (E40-E50) double-sided circular weft knitting machine with the model number of Pulsar-2.8 is mainly used for producing chemical fiber raw materials with the raw materials of 20D-40D, and the debugging process has the following problems: if the conventional sinking-loop triangle 100 is used, the yarn finishing part is insufficient due to the over-short needle returning part 110, the yarn tension is easy to fluctuate when the upper needle cover knitting needle bends the yarn, and the surface of the knitted fabric is easy to form horizontal stripes, thereby affecting the quality of the fabric surface.
Above-mentioned two-sided circular weft knitting machine, through with the 110 planar segment extension of back of the needle portion, make down the knitting needle contain the needle line arc volume and increased several times (specifically be 5 times), required yarn volume when going up the knitting needle looping, can evenly distributed to down on the 6 knitting needles of knitting needle, the atress is even between the positive and negative coil that knitting needle formed from top to bottom, difficult production coil distortion, the fabric surface is level and smooth, coil balance about going up, be difficult to form the horizontal bar, the fabric can not produce the turn-up phenomenon, improve the non-volatility and the extensibility of fabric, and the cloth cover third dimension is strong, upper and lower cloth cover light transmissivity is good.
As shown in fig. 2 and 3, in the present embodiment, the weft knitting machine further includes a cam adjusting part 200 mounted on the body of the weft knitting machine, and the cam adjusting part 200 is used for adjusting the positions of the sinker cam 100 and the knitting needles, thereby adjusting the size of the cylinder opening.
In the present embodiment, the triangle adjusting part 200 includes a dial 220, an adjusting cam 210, a triangle mounting slider 230; the adjusting cam 210 is rotatably installed on the weft knitting machine, the dial 220 is sleeved at one end of the adjusting cam 210, the other end of the adjusting cam 210 is provided with a spiral groove, one end of the triangle installation sliding block 230 is clamped in the spiral groove, and the other end of the triangle installation sliding block is fixed on the sinking ring triangle 100.
