Abstract
The invention discloses a needle selecting upper-triangle of a computer flat knitting machine, which comprises a left block, a middle block and a right block. The left block of the needle selecting upper-triangle is of a strip shape, the upper edge of the left block is a straight line, and the lower edge of the left block is a needle selecting and moving track; two ends of the lower edge are bent upwards; the right block and the the left block needle of the selecting upper-triangle are same in shapes and are opposite in direction; the middle block is left-right symmetrical, two ends of the upper edge of the middle block are bent downwards, and the lower edge of the middle block is a needle selecting and moving track; the bending positions of the upper edge of the middle block and the track of the lower edge of the middle block form an acute angle; 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 upper-triangle, so that the tracks of the lower edges of the three segments of needle selecting upper-triangles are continuous; and each block of needle selecting upper-triangle is provided with at least two thread fixed holes. According to the needle selecting upper-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 invention belongs to technical field of knitting machinery, relate in particular on a kind of computer flat knitting machine needle selection and protect the mountain.
Background technology
Protect the mountain on 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 on 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 on the needle selection.Make simply though protect the mountain on this type,, make the motion process of needle selection stable inadequately, and vibrations are bigger, are prone to cause the damage at stitch or other positions because the track that takes the needle that protects the mountain on this type and provide needs stitch often to do the right angle turnover.
Summary of the invention
The present invention aims to provide on a kind of computer flat knitting machine needle selection that can effectively address the above problem and protects the mountain.
For this reason, technical scheme of the present invention is such: protect the mountain on the computer flat knitting machine needle selection, comprise three of left, center, right, protect a left side, mountain piece on the described needle selection and be strip, the upper edge is a straight line, and the lower edge is the needle selection Cam Track, and the two ends, lower edge are bending upwards; 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 two ends, upper edge bend downwards; The lower edge is the needle selection Cam Track, and bending place, upper edge and lower edge track 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 on the needle selection makes the lower edge track that protects the mountain on three sections needle selections continuous; Protect the mountain on the every needle selection at least two screw thread fixing holes are arranged.
As the further technical scheme of the present invention; Upwards the track and the upper edge angle of bending are 37 ° to protect Cam Track left side, piece lower edge, a left side, mountain on the described needle selection; The right side upwards track and the upper edge angle of bending is 36 °; There is an isoceles triangle groove in the left side near the bending place; The drift angle of isoceles triangle groove is 84 °; There is a trapezoidal groove in the left side near midpoint, and the left side of trapezoidal groove and upper edge angle are 48 °, and right edge and upper edge angle are 36 °; It is symmetrical fully about center line to protect right piece in mountain and left piece on the described needle selection.
In addition; Protecting piece lower edge track in the mountain on the described needle selection has a downward isosceles trapezoid protruding; The dual-side angle of isosceles trapezoid is 84 °, and the center of isosceles trapezoid has two mutually about the isoceles triangle connected in star of center line symmetry, and the drift angle of isosceles triangle is 84 °.
Each turning angle of the present invention all adopts the best angle that protects the mountain on 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 on 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 on 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.
