Novel scissor device and working control method thereof

Abstract

The invention mainly relates to a novel scissor device. The novel scissor device comprises a scissor frame, wherein a rotating shaft is movably arranged on the scissor frame; scissors, a movable pieceand a pressing piece are sequentially arranged on the rotating shaft, and the rotating shaft can drive the scissors to rotate; the movable piece is movably mounted between the pressing piece and thescissors, the end of the pressing piece is provided with an opening, the opening is a yarn pressing opening, and the movable piece can rotate relative to the pressing piece; the movable piece is connected with a first connecting rod mechanism; the movable piece is connected with a first driving shaft through the first connecting rod mechanism; the two sides of the movable piece are matched with the yarn pressing opening to realize individual yarn pressing control of multiple yarns; the rotating shaft is connected with a second connecting rod mechanism. and the rotating shaft is connected witha second driving shaft through the second connecting rod mechanism; a hook cutter is glidingly mounted on the side of the scissor frame; and the second driving shaft can control and drive the scissorsand the hook cutter to move and work. The design structure is simple and ingenious, the control is stable, the various yarns can be individually pressed and controlled, and when multiple yarns are switched, the yarns do not need to be reconnected, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a novel scissors device and an operation control method thereof, belonging to the technical field of knitting machinery. Background technique [0002] The flat knitting machine is used for knitting gloves, socks and other items. The flat knitting machine includes a scissor device, which is used to cut the yarn. The scissor device includes scissors and hook knives. The scissors and hook knives need to cooperate with each other to complete the work. , the control structure of the existing scissors device is complicated and the control is unstable; when the scissors and the hook knife work together, they need to be assisted by a thread pressing mechanism. The thread pressing mechanism is used to press the yarn to prevent yarn jumping after the yarn is cut , if thread skipping occurs, the yarn needs to be reconnected in series, which is very troublesome; when working, the thread pressing mechanism first presses the yarn, and then t...

[0002] The flat knitting machine is used for knitting gloves, socks and other items. The flat knitting machine includes a scissor device, which is used to cut the yarn. The scissor device includes scissors and hook knives. The scissors and hook knives need to cooperate with each other to complete the work. , the control structure of the existing scissors device is complicated and the control is unstable; when the scissors and the hook knife work together, they need to be assisted by a thread pressing mechanism. The thread pressing mechanism is used to press the yarn to prevent yarn jumping after the yarn is cut , if thread skipping occurs, the yarn needs to be reconnected in series, which is very troublesome; when working, the thread pressing mechanism first presses the yarn, and then the scissors cut the yarn. After the yarn is cut, it is still pressed by the thread pressing mechanism, so that The yarn will continue to be used for weaving

[0003] The structure of the existing crimping mechanism is complex. The crimping mechanism can only hold down one kind of yarn, or can only hold down and release multiple kinds of yarns at the same time, and cannot be controlled separately; when weaving later, multiple kinds of yarns need to be switched , it can only be realized by rewiring, which affects work efficiency
