Abstract
The utility model relates to a textile mechanical workpiece, in particular to a computerized flat knitting machine latch needle used for weaving a sweater. The computerized flat knitting machine latch needle used for weaving the sweater comprises a needle body, a needle head, a needle tail and a loop transfer sheet. A needle latch and a needle latch pin are arranged on the needle head. The computerized flat knitting machine latch needle used for weaving the sweater is characterized in that an isosceles trapezoid notch is formed on the surface of the needle head, an isosceles trapezoid opening is formed in the position, opposite to the loop transfer sheet, of needle body, and a rectangle notch groove is formed at the bottom of the needle body. The computerized flat knitting machine latch needle used for weaving the sweater has the advantages of being capable of effectively achieving loop transfer weaving, convenient to use, simple in structure, capable of prolonging service life of the latch needle and the like.
Description
Technical field
The utility model relates to a kind of textile machine workpiece, especially relates to a kind of for the woven Computerized flat knitting machine latch needles of sweater.
Background technology
As everyone knows, latch needles is a large amount of main loop-forming elements that use in the computer flat knitting machine, in lopping braiding process, by with the head triangle effect of Computerized flat knitting machine, finish a series of braid movements such as lopping, tuck, flotation line and barring-on, knit out colourful institutional framework flower shell fabric.When particularly weaving the complex patterns such as some barring-ons at Computerized flat knitting machine, owing to require high to the transverse movement precision of front and back needle-bar and the control of latch needles, be very easy to produce the phenomenon of coverer syringe needle and the collision of adapter ring pin or friction, thereby make the failure of barring-on braid movement, cause the wearing and tearing of latch needles and the generation of broken needle phenomenon, make fabric produce the broken hole phenomenon, thereby affect the braid efficiency of Computerized flat knitting machine.Latch needles wants constantly to be subject to for a long time the active force of head triangle in the knitting process, the structure of latch needles self can change continuously, its brute force and elasticity can die down gradually, by the accumulation of long stress and strain, make latch needles produce fatigue damage and rupture and damage.The reason that latch needles produces fatigue damage is that the quality of latch needles itself and intrinsic frequency are excessive, the elasticity of latch needles is bad, thereby make latch needles with the percussion process of triangle in too early damage, and then affected the service life of latch needles and production efficiency and the processing cost of factory.
Summary of the invention
The utility model mainly is for the existing above-mentioned technical problem of prior art, and a kind of Computerized flat knitting machine latch needles that can efficiently finish the barring-on braiding, increase the latch needles life-span is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of for the woven Computerized flat knitting machine latch needles of sweater, comprise the needle body, syringe needle, backshank and barring-on sheet, syringe needle is provided with needle latch and needle latch pin, the surface that it is characterized in that described syringe needle offers the isosceles trapezoid otch, described barring-on sheet offers an isosceles trapezoid-shaped openings on the relative needle body position, and the bottom of the described needle body is provided with the rectangular slits groove.The design of latch needles syringe needle and needle body place trapezoid-shaped openings can make Computerized flat knitting machine effectively avoid friction and collision between the latch needles in barring-on braiding process, greatly reduces the generation of fabric broken hole phenomenon, improves the quality of product.Active force when the design of rectangular slits groove can reduce straight-bar machines work effectively between latch needles and triangle, thereby the fatigue damage of reduction latch needles, the service life of prolongation latch needles.
As preferably, the top mid point of described isosceles trapezoid otch and the arc center of syringe needle point-blank, the height of isosceles trapezoid otch is 3/4ths of syringe needle diameter.Can make Computerized flat knitting machine effectively avoid friction and collision between the latch needles in barring-on braiding process, greatly reduce the generation of fabric broken hole phenomenon, improve the quality of product.
As preferably, the height of described isosceles trapezoid opening is 2/3rds of corresponding needle body width.Prove that by experiment when this design was carried out the barring-on braiding at Computerized flat knitting machine, the coverer syringe needle can be finished barring-on braiding process effectively smoothly by the adapter ring sheet of adapter ring pin and the opening of the needle body, has reduced collision and the friction of latch needles.
As preferably, the distance of described rectangular slits groove the high bottom in the barring-on sheet to the needle body, described rectangular slits groove wide be the needle body wide 1/3rd, and center line in the needle body in the heart.The length of rectangular slits groove can be according to the pin number different appropriate design sizes of latch needles, and the design of rectangular channel has effectively alleviated quality and the intrinsic frequency of latch needles, has improved the elasticity of latch needles.
Therefore, the utlity model has can efficiently finish barring-on braiding, easy to use, simple in structure, increase the characteristics such as latch needles life-span.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Accompanying drawing 2 is resulting lateral cross section cutaway views of B-B line in the accompanying drawing 1.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
Shown in Figure of description 1,2, described in the utility model a kind of for the woven Computerized flat knitting machine latch needles of sweater, comprise the needle body 1, syringe needle 2, needle latch 3, barring-on sheet 4, needle latch pin 5, backshank 6, isosceles trapezoid opening 7, rectangular slits groove 8 and isosceles trapezoid otch 9.At the otch 9 of a kind of isosceles trapezoid of surface design of syringe needle 2, the top mid point of isosceles trapezoid otch and the arc center of syringe needle point-blank, and the height of isosceles trapezoid otch is 3/4ths of syringe needle diameter.Cut out the trapezoidal opening of isosceles 7 at the barring-on sheet 4 relative needle bodys, and the height of isosceles trapezoid otch is 2/3rds of corresponding needle body width.This design is when carrying out the barring-on braiding, and the coverer syringe needle can smoothly by the adapter ring sheet of adapter ring pin and the opening of the needle body, reduce collision and friction between the latch needles.In the bottom design of the needle body 1 a rectangular slits groove 8, the distance of rectangular slits groove the high bottom in the barring-on sheet to the needle body, wide be the needle body wide 1/3rd, and center line in the needle body in the heart, grow according to the pin of latch needles and number can carry out appropriate design.The design of rectangular channel has alleviated quality and the intrinsic frequency of latch needles, has improved elasticity and the impact resistance of latch needles.
Adopt Computerized flat knitting machine latch needles described in the utility model, can make Computerized flat knitting machine effectively avoid collision and friction between the latch needles in barring-on braiding process, reduce the generation of fabric broken hole phenomenon.The elasticity of latch needles obtains larger improvement, and the fatigue durability of latch needles improves.
Should be understood that this embodiment only is used for explanation the utility model and is not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
