Description

Structure of knitting needle loop-transferring reed of flat knitting machine Technical Field The utility model relates to the field of computerized flat knitting machines, in particular to a structure of a knitting needle loop-transferring reed of a computerized flat knitting machine. Background The computerized flat knitting machine is one kind of double needle board latch needle weft knitting loom, and the knitting needle inside the needle slot of the needle bed is driven to move up and down via the machine head and the triangular mechanism set on the triangular bottom board of the machine head, i.e. the triangular system drives the knitting needle inside the needle slot to complete the knitting of fabric via the cooperation of the triangular mechanism and the drawing mechanism. The knitting needle comprises a compound needle with a needle hook and a latch needle separated, and a common crochet needle with a latch needle (needle latch) pivoted below the needle hook, and in the structure of the latter, a needle turning piece (loop transferring piece) for loop transferring is arranged at the side edge of the needle body, the end part of the needle turning piece extends to a needle rod below the needle hook and forms a certain gap with the needle rod, namely the needle turning piece is used for expanding loops when the loops are transferred between the front needle bed and the back needle bed so as to be beneficial to the penetration of a loop connecting needle. Referring to the figure of CN215404847U, after the needle hook of one side hooks the thread, the needle hook of the loop-joining needle of the other side penetrates from between the needle turning piece and the needle bar, moves between the needle turning piece and the needle body, and continues to extend upwards, at this time, the latch of the loop-joining needle is opened under the action of the loop due to the existence of the loop. However, with the improvement of the knitting requirement, the knitting needles on the needle bed are distributed more and more densely, the stitch pressure of the stitch is larger, so that the gap between the stitch and the needle bar is too small, and the needle plate is generally longer, so that the needle bed at the middle part can generate micro deformation, the latch of the loop-joining needle can not be opened by the stitch hung at the junction of the needle bar and the needle body, and the loop transfer failure is caused. Therefore, the inventor further research and develop a structure of a knitting needle loop-transferring reed of a flat knitting machine, and the scheme is generated. Disclosure of utility model The utility model aims to provide a structure of a knitting needle loop-transferring reed of a flat knitting machine, which can ensure the success rate of opening the needle loop in the loop-transferring process of the flat knitting machine. In order to achieve the above object, the technical scheme of the present utility model is as follows: the structure of the knitting needle loop-transferring reed of the flat knitting machine comprises a needle bar, a needle body and a needle turning piece, The needle turning piece is provided with a needle shifting protrusion at the junction of the needle rod and the needle body, and the needle shifting protrusion can open the needle tongue of the moving loop needle. The needle turning piece is arranged on the side edges of the needle body and the needle bar, the needle body and the needle bar are of an integral structure, but the widths of the needle body and the needle bar are obviously different, a thread blocking part (generally L-shaped bent angle) is formed on one side of the junction, so that the needle turning piece and the needle bar are respectively defined by relative widths for explanation, when the loop is transferred, the needle hook of the loop connecting needle moves in a gap between the needle turning piece and the needle bar as well as the needle body, the needle tongue of the loop connecting needle needs to be opened first, the needle hook of the loop connecting needle hooks the loop, and the loop transferring action is completed, and the loop connecting needle can be opened more easily in the moving process due to the existence of the needle shifting protrusions, so that the success rate of the loop transferring is improved. Further, the shifting needle protrusion comprises an apex, and both sides of the apex are smooth inclined sides. The purpose of the needle-pulling projection is to open the latch of the tuck-stitch needle without blocking the movement of the tuck-stitch needle. Further, the needle shifting protrusion extends outwards from the side edge of the needle turning piece and is turned over again, and the top point of the needle shifting protrusion is not contacted with the needle rod or the needle body when the needle turning piece is not pressed. The needle pulling protrusion can be better aligned with the movement track of the nee
