Background
The existing triangular weaving system for flat knitting machines for gloves, socks, scarves and the like has the following defects:
1. when the flat knitting machine is used for knitting, most needles in each row do not participate in work, the unwoven needles are lifted by an inclined plane to enter a needle selection triangular track when passing through a needle selection return triangle, and are pressed into a needle bed to be separated from the triangular track after passing through a needle selector, so that needle selection presser feet need to repeatedly rub with blades of the needle selector, the blades cannot completely press the needle selection from a lower needle selection triangle after being worn for a period of time, and the phenomena of disordered needle lifting and defective products can occur when the selected needle triangle is hung occasionally; the abrasion is serious, the stitch is just in contact with the edge of the triangular boss, and when the stitch is not lifted, the stitch can not be lifted and can not be attached to the inclined plane of the triangular boss, so that the needle selection triangle is extruded and impacted, the situations of needle bed groove deformation, needle blocking, needle firing and the like are caused, therefore, in the production process, the needle selector, the needle selection piece and the triangular plate need to be frequently replaced, the needle bed needs to be replaced when the needle firing is serious, and the replacement and repair process is difficult. From the analysis, the needle selector selects the needle repeatedly, the repeated entering and exiting of the stitch in the triangular track is one of the important reasons of multiple faults and unstable putting of the machine, meanwhile, the left needle selector and the right needle selector select once each line to determine the working state of each needle, the actions are frequent, the machine head running speed is limited by the working time of the needle selector, the machine head running speed is slow, and the efficiency is low;
2. in the prior flat knitting machines, an intermediate piece A (high position) is knitted, an H (middle) position hangs a mesh, and a B (low position) is not knitted, namely, a mesh hanging press block is arranged at the middle position of an intermediate piece control area, a track is reserved at the high position for high position intermediate piece needle walking, a needle selection piece is pushed from the low position to the high position by a needle pushing triangle, the intermediate piece is pushed to the A (high) position, and is pressed back to the B (low) position by a needle cleaning triangle, so that the abrasion of the triangle and a stitch is easily caused, and the phenomenon of needle leakage caused by sliding out of the track is also easily generated.

The back of the triangle bottom plate 24 is provided with a driving control mechanism for controlling the lifting of the stitch cam 3, the rubber band cam 1, the movable needle cleaning cam 10, the needle selecting return cam 19 and the left and right needle pushing cams 16 and 17, and the driving control mechanism in the prior art is composed of a plurality of motors and a plurality of electromagnets, so that the size of the machine head 29 is overlarge, the weight is large, and the failure rate is high. For this purpose, the present embodiment provides a new driving control mechanism, as shown in fig. 3, 4, 5, 6, 28, which is a schematic three-dimensional structure diagram of the back surface of the triangular bottom plate 24, the driving control mechanism includes a double-output shaft motor 25, two rotating shafts 25.1 connected with two output ends of the double-output shaft motor 25, a first rocker 27 and a second rocker 28, a first cam 25.2 and a second cam 25.3 are fixed on the rotating shaft 25.1 corresponding to the knitting area, a third cam 25.4, a fourth cam 25.5 and a return cam 25.6 are fixed on the rotating shaft 25.1 corresponding to the needle selection area, a first lifting shaft 26 capable of lifting on the triangular bottom plate 24 is arranged on each of the stitch cam 3, the elastic triangle 1, the movable needle cleaning triangle 10 and the left and right needle pushing triangles 16, 17, a first bearing 26.1 matched with the corresponding cam is arranged on each of the first lifting shaft 26 capable of lifting motion on the triangular bottom plate 24, and a first bearing 26.1 on the stitch triangle 3 is matched with the periphery of the first cam 25.2, the bearing I26.1 on the left push pin triangle 16 is matched with the cam III 25.4, and the bearing I26.1 on the right push pin triangle 17 is matched with the cam IV 25.5. The center of the first wane 27 is rotationally connected with the triangular bottom plate 24, one end of the first wane is provided with a second bearing 26.2 matched with the second cam 25.3, and the other end of the first wane is used for controlling the first lifting shaft 26 of the movable needle cleaning triangle 10 to act. The center of the second wane 28 is rotatably connected with the triangular bottom plate 24, and two ends of the second wane are respectively embedded into the movable needle cleaning triangle 10 and the first lifting shaft 26 of the elastic triangle 1. When the first wane 27 presses down the first lifting shaft 26 of the movable needle cleaning triangle 10 under the control of the second cam 25.3, the second wane 28 can lift the first lifting shaft 26 of the elastic triangle 1 due to the existence of the second wane 28, at the moment, the elastic triangle 1 overcomes the spring force, and is in a descending position when viewed from the front, and the movable needle cleaning triangle 10 is in a lifting position; on the contrary, when the second cam 25.3 can not withstand the second bearing 26.2, the first rocker 27 can not provide the pushing-down force for the first lifting shaft 26 of the movable needle cleaning triangle 10, at the moment, the first rubber string triangle 1 resets under the action of the spring force, the first lifting shaft 26 of the first rubber string triangle 1 is driven to descend, and under the action of the second rocker 28, the first lifting shaft 26 of the movable needle cleaning triangle 10 is driven to ascend, at the moment, the movable needle cleaning triangle 10 is in the descending position and the rubber string triangle 1 is in the ascending position when being seen from the front.
