Warp loom guide bar assembly

Abstract

The invention relates to a guide bar assembly of a warp knitting machine, comprising a tension frame support, a guide bar fixing frame, guide bars, figure knitting drums and a motor. The figure knitting drum is two and respectively arranged at the left and the right side of a machine frame; a rocking arm shaft is also positioned at the left and the right side of the machine frame respectively; the guide bars are divided into two groups; the rocking arm shafts are provided with rocking arms that are corresponding to one group of guide bars; main mandrils are connected to the rocking arms, and the guide bars are connected with the corresponding main mandrils and the rocking arms are propped in motion by mutually corresponding figured pattern card chains, which are of the same side and are on the figure knitting drums; the left and the right of the machine frame are provided with a guide bar resetting mechanism respectively; a motor promotes the two figure knitting drums to rotate through a transmission mechanism. The left side and the right side of the machine frame in the invention are provided with the figure knitting drums; the guide bars, which are divided into two groups, are steel sheet guide bars, and can meet the requirement for complex structure and figures. The guide bars of the invention can traverse stably and accurately, and have good linearity.

Description

technical field [0001] The invention relates to parts of a warp knitting machine, in particular to a bar device for a warp knitting machine. Background technique [0002] The bar traversing device is one of the main components of the warp knitting machine. The bar traversing movement determines the distribution of the loops formed by the warp yarns on each bar in the fabric, thus forming different weave structures and patterns. The pull-type bar traversing device disclosed in the utility model patent specification No. 2727203Y authorized by China is a bar traversing device that improves the traditional warp knitting machine bar device. The traditional warp knitting machine bar device includes bar fixing frame, sprocket, worm, worm wheel, knitting drum, flower plate chain, extension device, ejector rod, bar, and the bar is installed on the bar fixing frame. . The flower plate chain is driven by the knitting flower roller and its transmission device, and ...

AI Technical Summary

Problems solved by technology

Both of the above two traverse devices have only one knitting drum, and the knitting board chains that can be installed on the knitting drum are limited, and the number of comb bars that can be driven is limited, about 40

Secondly, because the thickness of the traditional bar is relatively thick, generally 7-8mm, which also limits the increase in the number of bars on the bar fixing frame, the structure of the above-mentioned bar traversing device can no longer meet some complex organizational structures and patterns. weaving requirements
