Double needle cylinder hosiery machine is a hosiery machine that uses upper and lower needle cylinders to knit medium and short socks. It can produce socks of various tissues such as plain needle, rib, double reverse, jacquard, adding yarn, horizontal stripe, ring, etc.
A hosiery machine for knitting medium and short stockings with upper and lower needles. It can produce socks of various tissues such as plain needle, rib, double reverse, jacquard, adding yarn, horizontal stripe, ring, etc. The upper needle cylinder groove and the lower needle cylinder groove of the double needle cylinder hosiery machine are opposite to each other. Its main looping parts include double headed tongue needle, needle guide piece and sinker, and the knitted pattern socks also need foot pieces and jacquard pieces. The double head latch needle is knitted under the action of the needle guide, one end of which is engaged with the needle guide, and the other end is knitted. When the double head latch needle is controlled by the lower needle guide, the upper needle hook is used to weave the front coil. It can also transfer between the upper and lower needle cylinders according to the fabric texture requirements. When the upper needle cylinder is controlled by the upper needle guide, use the lower needle hook to weave the reverse coil. There is a work heel on the needle guide, which makes the double head tongue needle weave according to a certain needle route under the action of triangle. Another transfer heel makes the double headed tongue needle transfer under the effect of the transfer triangle. When knitting fancy socks, the foot piece is connected with the jacquard piece and is arranged below the lower needle guide piece for needle selection by the needle selection mechanism.
Double needle cylinder hosiery machine has two triangle systems, upper and lower. The lower triangle system has a bidirectional triangle seat, which is used for knitting the heel and head of socks with unidirectional and bidirectional rotary needles. The upper triangle system only allows the double head tongue needle to weave when the needle cylinder rotates in one direction. The upper and lower triangular systems have transfer triangles respectively, which can make the double head tongue needle transfer up and down. Double needle cylinder hosiery machine can also be equipped with two or three looping systems.
1. Feed the needle, and the lower needle guide rises to push the tongue needle upward;
2. In the hook, the tongue needle pushes the upper guide needle piece away and enters the hook of the upper guide needle piece;
3. Unhook, the lower guide needle piece is disconnected from the latch needle;
4. Reset, lower guide needle piece descends and returns to the original position. The sock knitted by double needle cylinder hosiery machine has good elasticity, but the mechanism is too complex, and electronic technology has been applied to simplify the mechanism.
