Needle bed device of flat knitting machine and flat knitting machine

Abstract

The invention discloses a needle bed device of a flat knitting machine and the flat knitting machine, and belongs to the technical field of flat knitting machines. The needle bed device comprises needle beds and inserting pieces, needle grooves are formed between the adjacent inserting pieces, lower knitting needles and lower needle jack pins are arranged in the needle grooves, conversion needle pins are arranged between the lower knitting needles and the lower needle jack pins, partition plates are further arranged in the needle grooves, upper knitting needles are arranged at the tops of thepartition plates, the rear ends of the upper knitting needles are connected with upper needle jack pins, push pieces are arranged at the bottoms of the upper needle jack pins, transition needle pins are arranged at the bottoms of the push pieces, the front ends of the conversion needle pins can be matched with the lower knitting needles or the transition needle pins, the lower needle jack pins candrive the lower knitting needles to move front and back through the conversion needle pins, and the lower needle jack pins can further drive the upper needle jack pins to swing upwards through the conversion needle pins, the transition needle pins and the push pieces. The number of the needle beds does not need to be increased, and assembly requirement of the needle bed device is reduced. The switching of the operation of the upper knitting needles and the lower knitting needles can be realized through the matching of the conversion needle pins, the transition needle pins and the push pieces,and the structure of the needle bed device is favorably simplified.

Description

technical field [0001] The invention relates to the technical field of flat knitting machines, in particular to a needle bed device of the flat knitting machine. In addition, the invention also relates to a flat knitting machine using the needle bed device. Background technique [0002] Existing flat knitting machines generally adopt a double needle position structure, and the front and rear needle beds are symmetrically arranged in a "eight" shape, and the knitting needles on the two needle beds are also arranged in a "eight" shape. The flat knitting machine with double-needle position structure generally adopts the knitting method of garment piece forming when knitting sweaters, and the knitted garment pieces are stitched to form a whole sweater. Because the stitching quality of sweaters depends on the proficiency of the stitchers, it is not conducive to improving the production efficiency and quality of sweaters. When a flat knitting machine with a double-needle position...

AI Technical Summary

Problems solved by technology

In this structure, the assembly requirements of the needle beds are relatively high, and it is difficult for the two needle beds on the same side to meet the shape and position tolerance requirements when the machine head is running. As the width increases, the difficulty of the needle selection mechanism that cooperates with the needle selection pins on the machine head also increases, and the manufacturing cost of the machine head is relatively high
