Guide bar device for yarn pressing warp knitting machine

Abstract

The invention discloses a guide bar device for a yarn pressing warp knitting machine. The guide bar device comprises a yarn pressing plate, a yarn pressing guide bar, at least one ground guide bar and a polyurethane guide bar; the yarn pressing guide bar is arranged on a first guide bar seat fixedly connected with a rack of the warp knitting machine; the guide bar device also comprises a swing shaft and a second guide bar seat fixedly connected with the swing shaft; the first and second guide bar seats are arranged on the front and rear sides of the yarn pressing plate respectively; the ground guide bar and the polyurethane guide bar are arranged on the second guide bar seat; the swing shaft is driven by a swing transmission mechanism to swing; the yarn pressing plate is driven by a planar connecting rod mechanism to move; and the yarn pressing guide bar is one or two separate full-gauge yarn pressing jacquard guide bars. The swing transmission mechanism preferably consists of a cam, a swing rod, a connecting rod and a swing arm; and the planar connecting rod mechanism preferably consists of a rotating shaft, an eccentric wheel, an eccentric sleeve, a V-shaped swing rod and a connecting rod. The guide bar device enables a knitting needle and the yarn pressing plate to work cooperatively, can knit richer patterns compared with the conventional yarn pressing warp knitting machine, is suitable for high speed, and has high production efficiency.

Description

technical field [0001] The present invention relates to a bar device of a warp knitting machine, in particular to a bar device of a yarn pressing type warp knitting machine, which has a yarn pressing plate, a yarn pressing bar, a ground bar and a spandex bar. It is installed on the bar seat fixedly connected with the frame of the warp knitting machine. Background technique [0002] Existing yarn pressing type warp knitting machine, such as the multi-comb yarn pressing type Raschel warp knitting machine used in large quantities at present, it comprises yarn pressing plate, 24 or 36 yarn pressing flower bars, ground bar and spandex comb Bar, the yarn-pressing flower bar, the ground bar and the spandex bar are all installed on the bar seat fixedly connected with the warp knitting machine frame. Due to the large number and heavy weight of the combing bar device, during the process of yarn forming, the combing bar is still, the yarn pressing plate is driven by the cam transmissi...

AI Technical Summary

Problems solved by technology

Due to the large number and heavy weight of the combing bar device, during the process of yarn forming, the combing bar is still, the yarn pressing plate is driven by the cam transmission mechanism to move up and down, and the movement of the knitting needle is controlled by Therefore, on the one hand, the pressing time given by the yarn pressing plate is very short, which makes the yarn pressing effect very unsatisfactory, which makes it difficult to coordinate the coordination between the knitting needle and the yarn pressing plate, so leakage often occurs. Production accidents such as needles and injections; on the other hand, due to the complex movement of the cam transmission mechanism of the yarn pressing plate, there is an impact during transmission, so this bar device cannot be suitable for high-speed knitting, and the production efficiency is low; The complex structure of the cam drive mechanism makes its processing more difficult; in addition, the bar device with this structure can only be limited to the situation where the bar arrangement on the front side of the yarn pressing plate occupies a small space. When occupying a large space, the yarn pressing plate and the knitting needle will have a reverse angle at this time, which is more unfavorable for the pressing effect, which makes it more difficult to coordinate the coordination between the knitting needle and the yarn pressing plate; moreover, The pattern woven by this bar device not only has a relatively small range of texture changes, but also cannot weave more novel patterns, so it cannot adapt to the current development trend of pattern diversification.
