Detailed Description

Example 1

The present invention will be described in further detail with reference to the accompanying fig. 1-3.

A flat knitting machine needle with a tensioning function is shown in figure 1 and comprises a frame 1, wherein the frame 1 is provided with a driving piece 11 matched with a normal flat knitting machine, and the driving piece 11 drives the flat knitting machine needle to perform knitting action through reciprocating motion.

The frame 1 is provided with a rotating mechanism 2, the rotating mechanism 2 comprises a rotating base 21, the rotating base 21 is fixedly arranged on the frame 1, and a fixed rotating shaft 22 is inserted in the center of the rotating base 21. The rotary shaft 22 passes through a sliding slot in the center of the rotary rod 23, and a shaft cover is provided at the end of the rotary shaft 22 to prevent the sliding rod from being separated from the rotary shaft 22. The rotary shaft 22 is slidable in the slide groove.

The back of the upper end of the rotating rod 23 is hinged with the left end of the front of the connecting rod 31 in the knitting needle body 3, and the back of the other end of the rotating rod 23 is hinged with the front of the left end of the hinged rod 41 in the pulling mechanism 4. The rear face of the left end of the connecting rod 31 is mounted on the driver 11. The right end of the connecting rod 31 is integrally formed with the tip of the needle head 32. The right end of the hinge lever 41 is integrally formed with the distal end of the pulling needle 42.

The working principle is as follows: as shown in fig. 2, the pulling needle 42 is disposed at an end of the knitted fabric opposite to the repair area, and the pulling needle 42 is fixed in a certain needle thread hole at the end. The pulling force in the fabric pulls the whole pulling mechanism 4 obliquely upwards, and the thread end hole is loosened. The pulling mechanism 4 drives the rotating rod 23 hinged with the pulling mechanism to slide, the sliding groove of the rotating rod 23 moves downwards relative to the fixed rotating shaft 22, and the rotating shaft 22 is closer to the upper end of the sliding groove. The rotating lever 23 in turn pulls the needle body 3 hinged thereto to move, and the needle head 32 moves obliquely downward. A pull-back action is established.

The knitting process begins and, as shown in fig. 3, the needle head 32 is positioned at the end of the fabric to be repaired. The driving piece 11 drives the knitting needle body 3 to move along the oblique upper direction, and the knitting needle head 32 carries out knitting action according to the working principle of the knitting needle of the normal flat knitting machine. The rotating lever 23 hinged to the needle body 3 is also moved obliquely upward, and the slide groove is moved upward relative to the rotating shaft 22, and the rotating shaft 22 is closer to the lower end of the slide groove. The pulling mechanism 4 hinged with the rotating rod 23 is integrally driven, and the pulling needle head 42 moves downwards along with the rotating rod, so that the fabric is pulled, and the thread end hole is tightened. Creating a pulling action. Can ensure that the thread end hole does not obstruct the knitting process due to excessive looseness. The driving member 11 drives the needle body to move along the oblique downward direction and retreat, so that the whole structure performs a pull-back action. The first complete pulling movement and the subsequent complete pulling back movement correspond to a complete knitting process.

The small reworked knitted fabric is knitted only by setting a knitting line of the complementary knitting section without switching equipment. The flat knitting machine knitting needle is provided with the pulling mechanism 4, and in the knitting process, the fabric is pulled, so that loose thread end holes are prevented from being hooked on the needle head, and faults caused by the loose thread end holes are avoided. The pulling is carried out by the knitting action, which not only can not obstruct the knitting process, but also can adjust and reset the pulling of the thread hole.

Example 2

A flat knitting machine needle with a tensioning function comprises a machine frame 1, wherein the machine frame 1 is provided with a driving piece 11 matched with a normal flat knitting machine, and the driving piece 11 drives the flat knitting machine needle to perform knitting action through reciprocating motion.

The frame 1 is provided with a rotating mechanism 2, the rotating mechanism 2 comprises a rotating base 21, the rotating base 21 is fixedly arranged on the frame 1, and the center of the rotating base 21 is provided with a rotatable rotating shaft 22. The rotary shaft 22 passes through a sliding slot in the center of the rotary rod 23, and a shaft cover is provided at the end of the rotary shaft 22 to prevent the sliding rod from being separated from the rotary shaft 22. The rotary shaft 22 is slidable in the slide groove and rotates along with the rotation of the rotary shaft 22.

The difference from embodiment 1 is that the rotary shaft 22 and the rotary base 21 are configured to be movable, that is, the rotary shaft 22 can rotate on the rotary base 21 without falling off, and the movement of the rotary shaft 22 is mainly to protect the rotary shaft 22 and the rotary rod 23, reduce the wear of the rotary shaft 22 and the rotary rod 23 caused by sliding, prolong the service life of the assembly, and ensure the smoothness of sliding.
