Abstract
The invention discloses a needle selecting lower-triangle of a computer flat knitting machine, which comprises a left block, a middle block and a right block. The needle selecting lower-triangle of the computer flat knitting machine is characterized in that the left block of the needle selecting lower-triangle is of a strip shape, the lower edge of the left block is a straight line, and the upper edge of the left block is a needle selecting and moving track; the right end of the lower edge of the left block is bent upwards, and the bending position and the needle moving track of the upper edge of the left block form an acute angle; the right block and the left block of the needle selecting lower-triangle are same in shapes and are opposite in direction; the middle block is left-right symmetrical, the lower edge of the middle block is a straight line, and the upper edge of the middle block is a needle selecting and moving track; two ends of the upper edge of the middle block are respectively bent downwards, and the bending positions and the lower edge of the middle block form acute angles; the bending positions of the upper edge of the middle block lean against the bending positions of the lower edges of the left block and the right block of the needle selecting lower-triangle, so that the tracks of the upper edges of the three segments of needle selecting lower-triangles are continuous; and each block of needle selecting lower-triangle is provided with at least two thread fixed holes. According to the needle selecting lower-triangle, the moving track transition of stitches in the needle selecting process is smooth, large vibration and shifting can not exist in the moving process, the failure rate is effectively reduced, and the service life of the machine is prolonged.
Description
Technical field
The present invention is a technical field of knitting machinery, relates in particular under a kind of computer flat knitting machine needle selection and protects the mountain.
Background technology
Protect the mountain under the computer flat knitting machine needle selection and be mainly used in the tracks of stitch when confirming needle selection, require speed steady in the motion process, the path is level and smooth, can not produce by a relatively large margin vibrations or sudden unplanned displacement.It is single to protect the mountain structure under the existing needle selection, adopts right-angle structure more, and it is vertical with the base promptly to protect each turning point side of mountain under the needle selection.Though this type protects down the mountain and make simply, because the track that takes the needle that protects the mountain under this type and provide needs stitch often to do the right angle turnover, makes the motion process of needle selection stable inadequately, and shake greatlyyer, be prone to cause the damage at stitch or other positions.
Summary of the invention
The present invention aims to provide under a kind of computer flat knitting machine needle selection and protects the mountain, and the motion process that can effectively solve needle selection is stable inadequately, and vibrations are bigger, is prone to the technical problem that causes stitch or other positions to damage.
For this reason, technical scheme of the present invention is such: protect the mountain under the computer flat knitting machine needle selection, comprise three of left, center, right; Protect a left side, mountain piece under the described needle selection and be strip, the lower edge is a straight line, and the upper edge is the needle selection Cam Track; The lower edge right-hand member is bending upwards, and bending place and upper edge Cam Track form acute angle; It is block-shaped identical and in the opposite direction with a left side to protect the right piece in mountain on the described needle selection; Piece self left-right symmetric in described; The lower edge is a straight line, and the upper edge is the needle selection Cam Track, and respectively there is a bending downwards at the two ends, upper edge; Bending place and lower edge form acute angle, and the bending place, upper edge leans against the bending place, lower edge of protecting mountain left side piece and right piece under the needle selection makes the track of Hu Shan upper edge under three sections needle selections continuous; Protect the mountain under the every needle selection at least two screw thread fixing holes are arranged.
As further technical scheme of the present invention; Protect under the described needle selection piece lower edge, mountain left side right-hand member upwards bending be 45 ° with the horizontal line angle, left piece upper edge Cam Track right part has a trapezoidal convexity, there is a trapezoidal groove at the middle part; The trapezoidal groove left side is right after a boss; In the middle of the boss triangular hill is arranged, boss is higher than right-hand component in the left-hand component of triangular hill, and the boss both sides transit to the upper edge straight portion with hypotenuse; It is symmetrical fully about center line to protect right piece in mountain and left piece under the described needle selection.
In addition; Protect piece left-right symmetric in the mountain under the described needle selection, two ends, upper edge bending downwards are 45 ° with the horizontal line angle, and respectively there is a trapezoidal convexity at the two ends, upper edge; Each is a straight line with the bending place at two ends, upper edge two trapezoidal sides away from middle piece center line; There is a trapezoid boss center of middle piece, and there are two isosceles triangle convexities the center on the boss, and leg-of-mutton drift angle is 84 °.
Each turning angle of the present invention all adopts the best angle that protects the mountain under the computer flat knitting machine needle selection, and in the time of avoiding turning angle too small, knitting needle is smoothly smooth and easy inadequately.Knitting needle often needs to change height in the process of taking the needle; And offsets in height takes place because vibrations can not fit like a glove with desired trajectory through regular meeting in knitting needle when taking the needle, each section Cam Track that therefore requires to protect the mountain under the needle selection reaches appointed positions; Because the size of motherboard is limit; The lateral length of each piece can not be long, receives the length institute limit for height degree can't be up to standard when causing side section turning angle excessive, and the present invention can avoid this situation.The both sides of piece all have a slope among the present invention, and are corresponding with the slope of left piece and right piece, and three can splice and coincide, and make the Cam Track that protects the mountain under three needle selections can level and smooth linking together.In addition, the present invention all uses fillet in each turning point, the flatness when further promoting knitting needle.
The present invention can make the movement locus transitions smooth of stitch in the needle selection process, and can not occur in the motion process effectively reducing fault rate than big bang and skew, prolongs the service life of machine.
