Jacquard electronic needle block for integrated warp knitting machine

Abstract

The invention discloses a Jacquard electronic needle block for an integrated warp knitting machine. A stand column is arranged on a base of the needle block. A via hole is formed in a circuit board. The circuit board penetrates through the via hole through a connecting part and is fixed to the stand column. The connecting part serves as a power source cathode of the circuit board. The circuit board is provided with a conductive pressing needle. A through hole is formed in the base of the needle block. The conductive pressing needle penetrates through the through hole to serve as an anode wire of an input power source. A piezoelectric ceramic piece element is bonded to a Jacquard needle. A coral-shaped stand column is arranged on the base of the needle block. A patch plug is arranged on the circuit board. The Jacquard needle is fixedly clamped to the coral-shaped stand column. The conductive part of the tail portion of the Jacquard needle is inserted into the patch plug. A drive and control circuit and an actuator are integrated, line connection of a system is simplified, and generalization of Jacquard guide bars of the warp knitting machine is achieved.

Description

Technical field: [0001] The invention belongs to the field of jacquard electronic needle blocks for warp knitting machines, in particular to an integrated jacquard electronic needle block for warp knitting machines. Background technique: [0002] Jacquard technology plays an important role in the jacquard production process of warp knitting products. It is one of the three key jacquard technologies of warp knitting surface comb jacquard, comb jacquard and single needle jacquard. With the comprehensive use of jacquard bars, various new warp knitting jacquard crafts and products continue to emerge. Nevertheless, the jacquard device adds various restrictions to the design and application of the jacquard machine while adding the jacquard single-needle jacquard function to the warp knitting machine. First of all, whether it is a single-needle bed Jacquard machine or a double-needle bed warp knitting machine, the installation position of the jacquard bar can only be placed at the...

AI Technical Summary

Problems solved by technology

Nevertheless, while the jacquard device increases the jacquard single-needle jacquard function for the warp knitting machine, it also adds various restrictions to the design and application of the jacquard machine

First of all, whether it is a single-needle bed Jacquard machine or a double-needle bed warp knitting machine, the installation position of the jacquard bar can only be placed at the rear of the needle bed, or in the middle of the two needle beds, that is, all The middle position of the ground bar to avoid hindering the removal and threading of other yarn guide bars; secondly, the Jacquard bar itself filled with Jacquard guide needle blocks cannot be disassembled, and can only be installed on the Jacquard bar. The yarn is threaded needle by needle after being put on the machine, so the threading workload of the jacquard bar is heavy and extremely difficult

[0003] The reason is that the current existing jacquard needle blocks using piezoelectric ceramic jacquard needles adopt a method in which the driving part is separated from the jacquard yarn guide needles in terms of control structure: that is, all jacquard needle blocks They are all installed on the guide bar, and all the corresponding driving electric control boards are installed on the fixed machine beam of the warp knitting machine. The two are connected by flat cables. Since each jacquard needle block contains 16 Jacquard needles, each jacquard needle requires an independent drive cable, and each bar contains about 200 jacquard needle blocks, which makes thousands of jacquard needles connected from the drive plate to the jacquard bar on the warp knitting machine Drive cables, these cables not only make it impossible to remove the jacquard bar from the machine for yarn threading, but also seriously hinder the removal and threading of other common yarn guide bars if the designed installation position is not suitable

The various restrictions and inconveniences in the design of equipment structure and in the process of equipment application have greatly restricted the richness of types of Jacquard warp knitting machines and the development speed of new craft products.
