Abstract
The invention discloses a pneumatic scissor clamp device in a flat knitting machine. The pneumatic scissor clamp device comprises yarn pull-broken needle hooks, scissor blocks, rubber blocks, scissor clamping blocks, a pressing rod, U-type connectors, cylinders and a scissor bottom plate, wherein the yarn pull-broken needle hooks are installed on the scissor bottom plate through the pressing rod, the tail ends of the yarn pull-broken needle hooks are connected with piston rods of the cylinders through the U-type connectors, the front end of the scissor bottom plate is sequentially and fixedly provided with a plurality of the scissor clamping blocks, the left upper corners of the scissor clamping blocks are provided with rotary shafts, the right upper corners of the scissor clamping blocks are provided with the rubber blocks, the rotary shafts are fixed to the scissor bottom plate, the scissor blocks are arranged on the rotary shafts in a sleeved mode and fixed through torsional springs, and the left upper corners of the scissor blocks are provided with sharp cutting edges. When the device works, the piston rods of the cylinders extend and retract to drive the yarn pull-broken needle hooks to be pulled to behind yarns and to move downward to reach the positions of the scissor blocks, the cutting edges of the scissor blocks cut off the yarns, and the yarns which are cut off are clamped under the mutual action of the rubber blocks and the yarn pull-broken needle hooks and cannot be loosened until the cylinders extend again.
Description
Technical field
The invention belongs to technical field of knitting machinery, particularly the pneumatic scissors clamp apparatus in a kind of flat machine.
Background technology
Flat machine, all with scissors apparatus, completes clamp and the function of cutting off yarn by scissors apparatus at present.In the prior art, straight-bar machines adopts and each side to use two scissors, but this structure is when braiding needs the colored type of multiple color yarn, there will be the phenomenon of yarn clipping, and can damage yarn during yarn clipping.Conventionally we can change these phenomenons by the adjustment of flower type technique, but this mode can increase the line number of operation, thereby increase man-hour, reduce operating efficiency.
Summary of the invention
Content of the present invention is in order to address the above problem, and the pneumatic scissors clamp apparatus in a kind of flat machine that can cut yarn yarn clipping when flower type is complicated is provided.
For this reason, technical scheme of the present invention is: the pneumatic scissors clamp apparatus in flat machine, is characterized in that: it comprises that yarn breaks pinhock, scissors piece, block rubber, scissors clamp, depression bar, u shaped connector, cylinder and scissors base plate; Described yarn is broken pinhock and is arranged on scissors base plate by depression bar, and end is connected with the piston rod of cylinder by u shaped connector; The head that described yarn is broken pinhock has a hook, and described hook is with cutting edge; Described scissors base plate front end is fixed some scissors clamps successively; Described yarn is broken pinhock between two adjacent scissors clamps; The described scissors clamp upper left corner has rectangular indentation, and the upper right corner has semicircle breach; Described rectangular indentation place has a rotating shaft, and described semicircle indentation, there has block rubber; Described rotating shaft is fixed on scissors base plate; Described scissors piece is enclosed within rotating shaft, by torsion spring, fixes; The described scissors piece upper left corner has a sharp cutting edge.
When the present invention works, break pinhock move up and down by the flexible drive of the piston rod yarn of cylinder, the yarn stretching out is broken pinhock and is moved to after yarn, moves downward; Due to the scissors piece certain angle that can rotate around the axis, and under torsion spring effect, scissors piece is pasting all the time yarn and is breaking pinhock; So when cylinder drives yarn to break pinhock to move downward the position of scissors piece, the cutting edge that the cutting edge of scissors piece and yarn are broken pinhock head interacts, yarn is cut off, and be jammed under the interaction that the yarn of cutting off is broken pinhock at block rubber and the yarn of an adjacent side, until stretching out Shi Caihui again, cylinder bleeds off.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and embodiments of the present invention, be described in further details.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Fig. 3 is yarn clipping schematic diagram of the present invention.
Fig. 4 is the partial enlarged drawing of Fig. 3.
The specific embodiment
Referring to accompanying drawing.The present embodiment comprises that yarn breaks pinhock 1, scissors piece 2, block rubber 3, scissors clamp 4, depression bar 5, u shaped connector 6, cylinder 7 and scissors base plate 8; Described yarn is broken pinhock 1 and is arranged on scissors base plate 8 by depression bar 5, and end is connected with the piston rod 71 of cylinder 7 by u shaped connector 6; The head that described yarn is broken pinhock 1 has a hook, and described hook is with cutting edge; Described scissors base plate 8 front ends are fixed some scissors clamps 4 successively; Described yarn is broken pinhock 1 between two adjacent scissors clamps 4; Described scissors clamp 4 upper left corners have rectangular indentation, and the upper right corner has semicircle breach; Described rectangular indentation place has a rotating shaft 9, and described semicircle indentation, there has block rubber 3; Described rotating shaft 9 is fixed on scissors base plate 8; Described scissors piece 2 is enclosed within rotating shaft 9, fixing by torsion spring 10; Described scissors piece 2 upper left corners have a sharp cutting edge 21.
During the present embodiment work, break pinhock 1 move up and down by the flexible drive yarn of piston rod 71 of cylinder 7, the yarn stretching out is broken pinhock 1 and is moved to after yarn 11, moves downward; Because scissors piece 2 can 9 turn an angle around the shaft, and under torsion spring 10 effects, scissors piece 2 is pasting all the time yarn and is breaking pinhock 1; So when cylinder 7 drives yarns to break pinhock 1 to move downward the position of scissors piece 2, the cutting edge that the cutting edge 21 of scissors piece 2 and yarn are broken pinhock 1 head interacts, yarn 11 is cut off, and be jammed under the interaction that the yarn 11 of cutting off is broken pinhock 1 at block rubber 3 and the yarn of an adjacent side, until stretching out Shi Caihui again, cylinder 7 bleeds off.
