All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1, in one embodiment, a double-sided circular weft knitting machine includes a weft knitting machine body and a tuck cam 100 for a needle cylinder knitting structure on the weft knitting machine body, the tuck cam 100 includes a loop back portion 110 and a corner portion 120 with an opening facing downward, which are arranged in a plane, and the loop back portion 110 and the corner portion 120 are connected by an arc connection portion 130 with an opening facing upward.
In this embodiment, the looper 110 can accommodate 6 needles, and the height of the looper 110 is 0.8 mm. The needle pressing angle of the front section of the arc-shaped connection part 130 is 52.5 degrees, and the needle lifting angle of the rear section of the arc-shaped connection part 130 is 52 degrees.
Compared with the traditional sinker cam 100 (right in the figure), the improved sinker cam 100 (left in the figure) in the double-sided circular weft knitting machine has a needle return height of 1.1 mm, which is higher than that of 1000.3 mm of the improved sinker cam 100. Wherein the maximum knitting needle stroke of the improved sinker cam 100 is 11.6 cm, and the stitch length is 15-23 mm/100.
For example, the production raw materials of double-sided circular weft knitting machine with the model number of Pulsar-2.8 (E40-E50) are chemical fiber raw materials with the production raw materials of 20D-40D, and the following problems exist in the debugging process: if the conventional sinker cam 100 is used, since the looper portion 110 is too short, the yarn finishing portion is insufficient, the yarn tension is liable to fluctuate when the upper needle covers the knitting needles for stitch-bonding, and the surface of the knitted fabric is liable to form a horizontal stripe phenomenon, thereby affecting the quality of the cloth cover.
According to the double-sided circular weft knitting machine, the plane part of the needle return part 110 is lengthened, so that the needle-containing arc quantity of the lower knitting needle is increased by a plurality of times (particularly by 5 times), the yarn quantity required by the knitting needle in the knitting process can be uniformly distributed on 6 knitting needles of the lower knitting needle, the stress between positive and negative loops formed by the upper knitting needle and the lower knitting needle is uniform, the loop distortion is not easy to generate, the surface of the fabric is smooth, the upper and lower loops are balanced, the transverse strip is not easy to form, the fabric cannot generate hemming phenomenon, the non-loosing performance and the extensibility of the fabric are improved, the three-dimensional sense of the fabric is strong, and the light transmittance of the upper and lower fabric is good.
As shown in fig. 2 and 3, in this embodiment, the weft knitting machine further includes a cam adjusting member 200 mounted on the weft knitting machine body, and the cam adjusting member 200 is used to adjust the positions of the sinker cam 100 and the knitting needles, thereby adjusting the size of the mouth of the needle cylinder.
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 triangular installation sliding block 230 is clamped in the spiral groove, and the other end of the triangular installation sliding block is fixed on the sinker cam 100.
In this embodiment, the adjusting cam 210 is provided with a spiral groove at one end of the triangular mounting slider 230, the maximum radius of the spiral groove is 5 mm, the minimum radius is 2.5 mm, and the maximum adjustment amount is 2.5 mm.
In this embodiment, the dial 220 is divided into 35 cells, and the rotation angle of each cell is 10.28 degrees.
In the present embodiment, the dial 220 rotates one frame, and the displacement of the sinker cam 100 is 0.07 mm
When the cam adjusting part 200 is in use, the rotary adjusting cam 210 drives the dial 220 to rotate synchronously, and the spiral groove drives the cam installing slide block 230 clamped in the rotary adjusting cam to move, so that the slide block moves upwards or downwards, and the sinking cam 100 fixed on the slide block is driven to be communicated with the knitting needle simultaneously. Specifically, the clockwise rotation cam of the dial 220 moves downward, and the counterclockwise rotation cam of the dial 220 moves upward. The size of the top end of the knitting needle relative to the cylinder opening of the needle cylinder can be controlled by the control mode, and the size of the knitting needle determines the size of the coil.
