Drive Structure and Control Device of Raschel Jacquard Machine

Abstract

The invention relates to a raschel jacquard warp knitting machine, in particular to a driving structure and a control device of the warp knitting machine. There are three jacquard rings inside the warp knitting machine, and the threads pass through the holes in the jacquard rings radially, and the traverse motion of the needle bed becomes a compound of the rotation of the jacquard ring and the synchronous vertical reciprocating motion of the needles. A jacquard ring consists of a cam and a lever on both sides. The cam has a closed-loop profile, the middle of the lever is provided with a pivot, and the upper end of the lever is hinged with a connecting rod. Side; the second jacquard ring and the third jacquard ring are directly driven by AC brushless servo motors A and B, the output shaft of the AC brushless servo motor is provided with a pinion, and the pinion is connected to the second jacquard ring and the third jacquard ring through a belt Ring teeth on the outside of the third jacquard ring. Through the improvement of its transmission device and control system, it overcomes the disadvantages of the traditional structure, such as too large volume and low efficiency of jacquard jacquard.

Description

technical field [0001] The invention relates to the field of material textiles, in particular to a Raschel jacquard warp knitting machine, a driving structure and a control device thereof. Background technique [0002] The Raschel warp knitting machine with Jacquard device is called Raschel Jacquard warp knitting machine, and the Raschel Jacquard warp knitting machine is mainly used to produce mesh jacquard fabrics, among which RSJ4 / 1 Jacquard warp knitting machine can Production of dense jacquard warp knitted fabrics for the following applications: [0003] (1) Upholstery fabrics: mesh curtains, tablecloths, sofa backrests and armrests with three-dimensional effects. [0004] (2) Decorative clothing fabrics: women's underwear, swimsuits, tights, sportswear, outerwear, scarves and shawls, etc. This type of fabric is the main product produced by foreign jacquard warp knitting machines in recent years. For example, RJWB6 / 2F Jacquard warp knitting machine can also knit the f...

AI Technical Summary

Problems solved by technology

[0010] However, in the market today, the driving structure in the Raschel jacquard machine generally adopts a linear structure, and the circular jacquard machine is limited by the limitation of the driving structure in the jacquard ring. Usually there is a cam structure, and the length of the groove profile inside the cam determines more machine cycles, thereby improving the efficiency of jacquard, so the larger the cam can improve the efficiency of jacquard, but many jacquard devices are equipped with larger cams , the structure of the overall device is too large and takes up a lot of space

[0011] Moreover, in the existing traditional jacquard technology, the shifting needle and the jacquard guide needle need to move horizontally, which affects the efficiency of jacquard jacquard. If the above process can be further optimized, the efficiency can be improved. The above problems urgently need to be resolved
