Embodiment Construction

[0026] see Figure 1 to Figure 7 The shown artificial vascular weaving pattern comb system of a warp knitting machine includes several pattern needles 1, several long plate-shaped bar seats 2 arranged along the width direction of the warp knitting machine, fan-shaped bar hangers 3 and several straight lines Drive mechanism; the lower end of the flower comb needle 1 is provided with a yarn guide hole 1-1, and each of the flower comb needles 1 is fixedly installed on each bar seat 2 by screws 16 at intervals, and each bar seat 2 is respectively Slidably installed on the bar hanger 3, and each bar seat 2 is arranged at intervals along the radial direction of the bar hanger 3, and each bar seat 2 is driven by a linear drive mechanism along the warp knitting The width direction of the machine traverses back and forth, and the bar hanger 3 is rotatably installed on the frame of the warp knitting machine and is driven by a driving device to swing back and forth along the front and ba...

Abstract

The invention discloses an artificial blood vessel knitting jacquard comb system of a warp knitting machine. The artificial blood vessel knitting jacquard comb system comprises a plurality of jacquard comb needles, a plurality of stripping comb seats arranged along the breadth direction of the warp knitting machine, a fan-shaped stripping comb hanger and a plurality of linear driving mechanisms. A guide eyelet is arranged at the lower end of each jacquard comb needle, each jacquard comb needle is fixedly mounted on each stripping comb seat, each stripping comb seat is slidingly mounted on the stripping comb hanger, all the stripping comb seats are arranged at intervals radially along the stripping comb hanger, each stripping comb seat is driven to traverse in a reciprocating manner by one linear driving mechanism, and the stripping comb hanger is rotationally mounted on a frame of the warp knitting machine, and is driven by a driving device to swing in a reciprocating manner along the forward-backward direction of the warp knitting machine. All the stripping comb seats are arranged at intervals radially along the stripping comb hanger in a pairwise face-to-face manner, and the guide eyelets of the jacquard comb needles mounted on the stripping comb seats arranged in pairs in pairwise face-to-face manner coincide with one another in a projection plane perpendicular to a breadth end face. Stripping combs of a jacquard comb can traverse in a reciprocating manner in the breadth direction as well as swing in a reciprocating manner in the forward-backward direction, and the requirement for artificial blood vessel knitting can be well met.

Description

technical field [0001] The invention relates to a bar system of a warp knitting machine, in particular to a bar system of a warp knitting machine for weaving artificial blood vessels. Background technique [0002] There are three kinds of artificial blood vessel weaving methods: weaving, weft knitting and warp knitting. Woven artificial blood vessels, such as Chinese patents, publication numbers CN101084846, CN101069757 and other disclosed structures, the weaving equipment used is a common rapier loom or a modified rapier loom, and the woven artificial blood vessel fabric has a tight texture , high strength, low porosity, and no need for pre-setting, but its compliance is poor, easy to loose edges, and the healing effect is not ideal. The disadvantages of weft-knitted artificial vascular fabrics are that they are easy to curl, longitudinally and transversely easy to delaminate, poor elastic recovery, and slow radial and longitudinal creep after implantation in the human bod...
