Through the adoption of the needle selection upper protective needle plate, the transition of the motion trail of stitches during the needle selection process is smooth, so that larger shake and shifting can be avoided during the moving process.
Description
Technical field
The utility model relates to technical field of knitting machinery, relates in particular on a kind of flat machine needle selection and protects the mountain.
Background technology
Protect the mountain on the flat 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 earthquake motion by a relatively large margin or sudden and be shifted unplannedly.It is single to protect the mountain structure on the needle selection in the past, 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.Change though protect on the existing needle selection on the structure of mountain, the Cam Tracks that tilt that adopt come for needle selection provides the level and smooth track that takes the needle more, and each deflection angle of Cam Track often can't be obtained the most suitable angle.
Summary of the invention
The utility model aims to provide on a kind of flat machine needle selection and protects the mountain, can provide deflection angle rational Cam Track for needle selection.
For this reason, the technical scheme of the utility model is such: protect the mountain on the flat machine needle selection, comprise three of left, center, right; Be installed on the motherboard, protect a left side, mountain piece on the described needle selection and be strip, the upper edge is a straight line; The lower edge is the needle selection Cam Track, and the two ends, lower edge are bending upwards, and 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, and the lower edge is the needle selection Cam Track; 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, and upwards the track and the upper edge angle of bending are 50 ° 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 isosceles trapezoidal groove in the left side near the bending place, and two drift angles of isosceles trapezoid groove are 140 °, and there is a trapezoidal groove in the left side near midpoint; The drift angle of the left side of trapezoidal groove is 132 °, and the drift angle of right edge is 144 °; 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 °; The center of isosceles trapezoid has two, and trapezoidal groove is 140 ° near the drift angle at center mutually about the trapezoidal groove of center line symmetry, and another drift angle is 135 °.
Each turning angle of the utility model all adopts the best angle that protects the mountain on the flat 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 utility model can be avoided this situation.The both sides of piece all have a slope in the utility model, 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, fillet is all used in each turning point of the utility model, the flatness when further promoting knitting needle.
The utility model 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.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explain.
Fig. 1 is the utility model left side piece sketch map.
Fig. 2 is the right piece sketch map of the utility model.
