Single-segment needle selecting method and equipment of computer braiding machine

Abstract

The invention discloses a needle selection method of single segment for computer knitter and the equipment adopting the method. In the invention, the stitch of needle body of needle selection is made of magnetic material; electromagnetic field, which can play the magnetic force to the stitch, is set in the needle selection machine; according to the direction transformation of magnetic force in the needle selection machine the movement position of each needle body of needle selection, which passes through the magnetic field, is confirmed; the needle selection of single segment is achieved. The invention adopts changing the direction of magnetic field to accomplish the action of needle selection. In a short time, by the force that takes an effect on the stitch of needle body of needle selection through the magnetic force, the selection to needle body is accomplished and the entering needle position is controlled so as to accomplish the whole needle selection work. So the invention does not adopt the needle selection of multiple segments and it only adopts the needle selection of single segment to accomplish the needle selection. The structure is very simple.

Description

Technical field: [0001] The invention relates to the technical field of knitting equipment, in particular to a single-stage needle selection method for a computerized knitting machine and equipment designed using the method. Background technique: [0002] See Fig. 1, 2, this is a common computerized flat knitting machine at present, and it comprises a double-sided needle plate group 02, is positioned at the head 01 on the double-sided needle plate group 02. The cross-section of the double-sided needle plate group 02 is "herringbone" shape, and a needle groove 020 is arranged on the needle plate group 02, and a group of knitting needles 03 are placed in the needle groove 020, and the knitting needles 03 are pressed by the scale 021. Each group of knitting needles 03 is composed of multiple (usually four) individual needles linked together. And on the inner surface relative to the needle plate group 02 of the machine head 01, a track chute formed by a plurality of triangular ...

AI Technical Summary

Problems solved by technology

The reason why this method is adopted is that due to the nature of the electromagnet itself and the decision of its own technical level, such as response time, it cannot achieve single-stage needle selection.

The biggest disadvantage of using this method is:

[0004] 1. It needs to install an electromagnet in the equipment, resulting in a complex structure of the product and high cost of the needle selector

[0005] 2. The electromagnet moves frequently and makes a lot of noise

[0006] 3. The working stability of the electromagnet is greatly affected by factors (temperature, fatigue strength, reaction speed and other factors)

[0007] 4. Large size, complex control logic, easy damage, short life

[0008] 5. Affected by the performance of the electromagnet and the technical level, it is difficult to achieve single-stage needle selection
