Description
Technical field
The invention belongs to the Knitting Machinery field, relate in particular to a kind of computer flat knitting machine and turn over needle construction.
Background technology
Existing computer flat knitting machine is in turning over the pin process; The stitch of knitting needle needs independent one and turns over the pin Cam Track; For knitting needle being provided this turn over the pin Cam Track; Turn over pin triangle or the knitting cam that are installed on the triangle motherboard of existing computer flat knitting machine need to increase the complete pin track that turns over according to turning over the pin Cam Track; Need higher production cost; And strengthened and turned over the area that pin trigonometric sum knitting cam takies, and then the size of triangle motherboard is also sharply increased.Use diverse two Cam Tracks owing to turning over pin action and braid movement in addition; Make that the position at knitting needle place is different after two kinds of releases; Causing just to need the knitting needle playback diverse two cover instructions; Thereby computer flat knitting machine needs comparatively complicated software systems; Production cost is very high, and also the operating technology level to the user has higher requirements.
Summary of the invention
The present invention is intended to propose a kind of computer flat knitting machine that can effectively address the above problem and turns over needle construction.
For this reason; Technical scheme of the present invention is such: computer flat knitting machine turns over needle construction; Comprise and turn over pin trigonometric sum knitting cam; Be installed on the triangle motherboard; There is the braiding track on the knitting cam surface, braiding Cam Track self left-right symmetric of braiding track, and the braiding track is positioned at the top of knitting cam; The described pin triangle that turns over is above knitting cam, and knitting cam has opening in the place, center above its braiding track; Have and turn over needle guide and can rotate around the rotating shaft of self to rotor, rotating shaft is positioned on the symmetry axis of braiding Cam Track, and there is limiting structure the rotor left and right sides, and limit, the left and right sides is symmetrical; The described pin triangle that turns over has the bottom that comprises two V-arrangements, and two V-arrangements are Cam Track, and about the symmetry axis symmetry of braiding Cam Track, close each other side direction the other side extends.Turn over needle guide and intersect at a end, form an acute angle away from rotating shaft to the Cam Track of rotor left and right sides side.
As the further technical scheme of the present invention; The described needle guide that turns over is installed between two V-arrangements that turn over the pin triangle to rotor; Make rotor when turning to institute's extreme position to a side, the extension and the corresponding side of rotor that turn over the V-arrangement of pin triangle base and opposite side are connected to form continuous Cam Track.In addition, the described needle guide that turns over also can be installed in the knitting cam top to rotor, makes rotor when turning to institute's extreme position to a side, and the top of the braiding track of this side and the side of rotor opposite side are connected to form continuous Cam Track.
Moving from left to right with the relative triangle motherboard of knitting needle below is example, illustrates that the present invention accomplishes the pin process of turning over of turning over the pin action and getting into, withdrawing from each triangle device.
When turning over needle guide when rotor is installed between two V-arrangements that turn over the pin triangle, turning over needle guide is the last stitch of knitting needle to the effective object of rotor.Computer flat knitting machine is done when turning over the pin action; Knitting needle is earlier moved and is raise by the pin Cam Track that turns over along the degree order triangle on the knitting cam left side of stitch down; Stitch touches and begins when turning over the pin triangle that the V-arrangement Cam Track moves along the left side on knitting needle; Covering the V-arrangement Cam Track promptly accomplishes the last stitch that turns over pin action back knitting needle and can touch and turn over the left side of needle guide to rotor; And promote to turn over needle guide and to rotor it is swung until turning over needle guide to the right to go to institute's extreme position to the limited structure control of rotor; This moment, the last stitch of knitting needle moved along turning over the left side of needle guide to rotor; When the last stitch of knitting needle is about to leave when turning over needle guide to the left side of rotor; The following stitch of knitting needle just in time gets into the opening of knitting cam in braiding track top; And then right-hand part part of continuing to move and get into the braiding track; Next knitting needle can move and finally withdraw from knitting cam along the second half section of braiding Cam Track, accomplishes the whole pin flow process of turning over.
When turning over needle guide when rotor is installed in the knitting cam top, turning over needle guide is the following stitch of knitting needle to the effective object of rotor.Computer flat knitting machine is done when turning over the pin action; Knitting needle is earlier moved and is raise by the pin Cam Track that turns over along the degree order triangle on the knitting cam left side of stitch down; Stitch touches and begins when turning over the pin triangle that the V-arrangement Cam Track moves along the left side on knitting needle; Covering the V-arrangement Cam Track promptly accomplishes the following stitch that turns over pin action back knitting needle and can touch and turn over the left side of needle guide to rotor; And promote to turn over needle guide and to rotor it is swung until turning over needle guide to the right to go to institute's extreme position to the limited structure control of rotor; It is continuous to the last base of braiding track right-hand part part of rotor left side and knitting cam that turn over needle guide this moment; The following stitch of knitting needle moves along turning over the left side of needle guide to rotor; And can leave smoothly and turn over needle guide to the left side of rotor and move into right-hand part part of braiding track; Next knitting needle can move and finally withdraw from knitting cam along the second half section of braiding Cam Track, accomplishes the whole pin flow process of turning over.
The present invention is in the second half section of turning over the pin process; The Cam Track that knitting needle uses is identical with the second half section of braiding process; Each triangle device need not being aimed at turn over pin provides complete track, reduces accessory size and production difficulty greatly, thereby reduces the production cost of computer flat knitting machine.In addition; Because after turning over the pin release; The residing position of knitting needle is identical with the residing position of knitting needle, braid movement end back; Knitting needle to be classified as and use identical program; Reduced the complexity of software systems; Further reduce the production cost of computer flat knitting machine, user's operation easier is reduced greatly.
