Description

Control mechanism for controlling sinker and flat knitting machine

[ technical field ] A

The invention discloses a control mechanism for controlling a sinker and a flat knitting machine, and belongs to the technical field of flat knitting machines.

[ background of the invention ]

The flat knitting machine carries out regular lifting motion through the knitting needle, and realizes the actions of loop withdrawing, yarn laying, opening closing, loop looping, yarn bending, loop releasing, loop forming and the like of the yarn, thereby finishing the knitting of the cloth. During the ascending process of the knitting needle, the loops gradually withdraw from the needle hook, the needle latch is opened, the withdrawn needle latch is hung on the needle rod, during the descending process of the knitting needle, the needle hook catches the newly placed yarn and draws and bends the yarn into the loops, meanwhile, the original loops are removed from the needle hook, the new loops penetrate through the old loops and are connected with the old loops in series, and a plurality of loop strings woven by a plurality of knitting needles are mutually connected into a braided fabric.

In the lifting process of the knitting needle, because the knitting needle rod has friction relative to the coil and the yarn has elasticity, the coil can float upwards along with the knitting needle, thereby influencing the smooth operation of the loop withdrawing. Therefore, the flat knitting machine is provided with the sinker device to help the knitting needle smoothly complete the action of withdrawing the loop, the sinker control mechanism is arranged on the machine head of the flat knitting machine, the random head transversely moves left and right during working, and the sinker operates under the action of the sinker control mechanism to complete the function of pressing the loop or the yarn.

The existing sinker control mechanism is generally divided into an up-down structure and a left-right structure, and the existing sinker control mechanism with the up-down structure has the defects that the working width of a sinker during pressing action is insufficient, the sinker is released when the knitting needle does not reach the maximum withdrawal height in the process of withdrawing a loop, and the knitting needle cannot completely withdraw the loop easily during local knitting, so that the knitted fabric is damaged. The existing left-right movement sinker control mechanism can ensure that the sinker has enough working width, but the depth of pushing the sinker is fixed, the pressing depth of the sinker can be adjusted only by manually disassembling a connecting structure between the sinker control mechanism and the sinker, and the consistency of the pressing depth of the sinker is difficult to ensure. When the pressing depth of the sinker satisfies the local knitting requirement, the stitch is easily broken when performing the tight stitch transfer, and the knitted fabric is damaged. Therefore, the existing sinker control mechanism cannot have the advantages of two structures of up-down movement and left-right movement, namely, the sinker can not be guaranteed to have larger working width and the pressing depth of the sinker is adjustable.
