Single-yarn control device of computer type Jacquard warp-knitting machine

Abstract

The invention relates to a single-yarn control device of a computer type Jacquard warp knitting machine, which comprises an upper yarn guide rod, a weight transmitter, an adjuster and a sliding seat, wherein the sliding seat can move on the upper yarn guide rod; a locking screw is arranged between the sliding seat and the upper yarn guide rod; a sensor of the weight transmitter is fixed on the sliding seat; a sensing roller is fixed on the sensor; the adjuster is provided with a servo motor and a roller bracket which are arranged on the sliding seat, a driving rubber roller connected to the roller bracket, and a floating rubber roller pressed on the driving rubber roller; the driving rubber roller is driven by the servo motor to rotate; and the sliding seat is also provided with a front yarn guide roller and a back yarn guide roller. The device better solves the problem that the connection of the front and the back sheets of a seamless forming product has seams because of the over loose of single yarn; the clearness of a hollow flower shape can be simultaneously guaranteed in knitting meshes, in particular the clear flower type with three-dimensional feeling can be knitted on the Jacquard surface layer of interval Jacquard fabrics with double needles, i.e. sandwich Jacquard fabrics..

Description

technical field [0001] The invention relates to a single yarn control device of a computerized jacquard warp knitting machine. Background technique [0002] The seamless forming product is generally woven on a double needle bed Jacquard warp knitting machine at present. The double-needle bed Jacquard warp knitting machine has an upper yarn guide rod, a middle yarn guide rod and a lower yarn guide rod. Sliding, in this process, the yarn enters the jacquard needle through the dividing needle fixed on the middle yarn guide rod and the spring tension piece fixed on the lower yarn guide rod. When the double-needle bed Jacquard warp knitting machine is knitting, the front and rear needle beds each form a piece of fabric. The operation law of the side yarns on both sides connecting the front and rear pieces is inconsistent with that of other warp yarns, and the yarns that need to be consumed are different. Under the condition of the same feeding speed, the tension of the side yar...

Problems solved by technology

When the double-needle bed Jacquard warp knitting machine is knitting, the front and rear needle beds each form a piece of fabric. The operation law of the side yarns on both sides connecting the front and rear pieces is inconsistent with that of other warp yarns, and the yarns that need to be consumed are different. Under the condition of the same feeding speed, the tension of the side yarns is different from that of other warp yarns. The tension is smaller than that of other warp yarns. Although the spring tension piece has a certain compensation effect, it cannot adjust the feeding speed and cannot adapt to the adjustment of the side yarn tension. Therefore, it is still easy to produce a gap at the connection between the front and back pieces, which affects the quality of the product. quality

In addition, when weaving large meshes or continuous small meshes, that is, continuous small yarn feeding, the amount of yarn provided to the mesh process is the same as that of other normal processes, and the mesh process The amount of yarn consumed is small, which reduces the tension of the yarn at the mesh part, resulting in the phenomenon that the mesh cannot be opened, resulting in blurred patterns and affecting the appearance of the fabric, especially for double-needle bed interval jacquard fabrics. Sandwich jacquard fabrics, especially
