Upper needle dial device of double-sided large jacquard machine

Abstract

The invention relates to the field of circular knitting machines, in particular to an upper needle dial device of a double-sided large jacquard machine. The upper needle dial device comprises an upper needle dial, an upper knitting needle, a middle core and an upper needle selector. The upper knitting needle is mounted on the upper needle dial, the middle core is arranged above the upper needle dial, the upper needle selector is arranged on the middle core, a cancellation cam is mounted on the middle core, an upper cam box is arranged at the outer end of the middle core, an upper jacquard cam is arranged at the lower end of the upper cam box, and the upper needle selector penetrates the middle core. The upper needle dial device is characterized in that insertion sheets are inserted in the upper needle dial, the upper needle dial is of a split type structure and comprises an upper outer needle dial and an upper inner needle dial, an upper jacquard sheet is mounted on the upper inner needle dial, is positioned below the upper needle selector and is matched with the upper needle selector, an upper connecting sheet is mounted on the upper outer needle dial and is matched with the upper jacquard sheet, the upper knitting needle is mounted on the upper outer needle dial, an integral circle of sheet pressure plate is arranged at the inner end of the upper jacquard sheet and is fixedly screwed beside the inner-diameter side of the upper inner needle dial by a bolt, and a plurality of springs are mounted between the sheet pressure plate and the upper inner needle dial, sleeve the bolt and are arranged in counter-bored holes. The upper needle dial device has the advantages that free upper-dial knitting jacquard weaving can be implemented by the double-sided large jacquard machine, the double-sided large jacquard machine can be excellently cooperatively work with the upper knitting needle and the upper needle connecting sheet, the upper jacquard sheet, the upper connecting sheet and the upper knitting needle are reasonably mounted in needle trays, and the needle dials are low in machining difficulty and machining deformation.

Description

technical field [0001] The invention relates to the field of circular knitting machines, in particular to a dial device on a double-sided jacquard machine. Background technique [0002] At present, the double-sided computerized jacquard circular knitting machines produced by domestic manufacturers can only be equipped with computerized jacquard devices on the outer ring of the lower cylinder, and in fact can only realize the computerized needle selection jacquard of the lower cylinder knitting needles. And upper knitting needle, then can only realize very limited regular fabric organization by the arrangement of two sections of triangles and the arrangement of two sections of knitting needles. The result of this is that the fabric samples produced by the traditional double-sided jacquard machine can only produce various patterns with distinct color differences on the front side, while on the back side, the flower shapes and patterns cannot be clearly reflected. Traditional ...

AI Technical Summary

Problems solved by technology

If the inner diameter of the dial is simply reduced and the distance between the mouth of the dial and the inner wall is increased, the processing of the entire dial will be quite difficult and deformation will easily occur.
