Small-caliber circular knitting machine plaiting device

Abstract

The invention discloses a small-caliber circular knitting machine plaiting device. The small-caliber circular knitting machine plaiting device is characterized by comprising a supporting rod fixed to the working face of a needle cylinder, a height adjusting device installed at the top end of the supporting rod, a rotation adjusting device connected with the height adjusting device, and a plaiting and yarn guiding rod connected with the rotation adjusting device. A plaiting and yarn guiding assembly is installed on the plaiting and yarn guiding rod and comprises at least one yarn guiding triangular support installed on the upper surface of the plaiting and yarn guiding rod, and a yarn guiding nozzle connected with the tail end of the plaiting and yarn guiding rod. Multiple yarn guiding holes arranged in parallel are formed in the head end of the yarn guiding nozzle. The small-caliber circular knitting machine plaiting device has the advantages that the structure is simple, operation is easy, control is stable, it can be achieved that yarn laying positions and angles are adjustable, multiple pieces of yarn (backing yarn and surface yarn) are introduced at the same time to meet the knitting requirements of different plaited fabrics, the application range is wide, and large-scale production and application are convenient.

Description

technical field [0001] The invention belongs to the technical field of textile machinery and equipment, in particular to a plating device for a small-diameter circular weft machine. Background technique [0002] Circular knitting machine is a knitting machine that uses knitting needles arranged on a circular needle cylinder to form a coil of yarn, and then connects a circular weft knitted fabric through a snare. It is mainly composed of a yarn feeding mechanism, a weaving mechanism, a pulling-roll It is composed of taking mechanism and transmission mechanism. Selecting different types and calibers of needle cylinders can produce cylindrical knitted fabrics used in industry, agriculture and biomedical fields. For example, small-diameter circular knitting machines can be used to prepare medical human body tubular stents, such as Chinese invention patent (publication number: CN103705325A ) The intestinal stent described in ) is all woven by a small-diameter circular weft machi...

AI Technical Summary

Problems solved by technology

Since the veil coils of the plating weave always overlap the ground yarn coils, there are special requirements for knitting needles, yarn guides, yarn tension, and plating angles during knitting. The process requirements are relatively high, and improper parameter design will affect The covering effect of two or more loops, which affects the appearance of the fabric

[0004] The existing plating device has complex structure, high production cost, troublesome installation and maintenance, and difficult adjustment of process parameters

The plating device with repeated punching can only effectively feed one yarn alone, or feed two yarns into one yarn guide hole at the same time, but the two yarns are easy to entangle with each other, and cannot meet the requirements of multi-layer weaving structure , and the yarn tension cannot be measured and adjusted online, such as the adding device described in the Chinese patent (publication number: CN204589494 U)
