A knitting mechanism of a double-needle bed warp knitting machine

Abstract

The invention discloses a knitting mechanism of a two-needle bar warp knitting machine. The knitting mechanism comprises a looping mechanism and a guide bar mechanism. The looping mechanism comprises a front knockover needle, a rear knockover needle, a front latch needle, a rear latch needle, a front sinker, a rear sinker, a front looping main shaft and a rear looping main shaft, wherein the front knockover needle and the rear knockover needle, the front latch needle and the rear latch needle, the front sinker and the rear sinker as well as the front looping main shaft and the rear looping main shaft are each arranged symmetrically. The guide bar mechanism comprises a front guide bar base, a rear guide bar base, multiple flower combs, multiple ground combs and a middle ground comb, wherein the front guide bar base and the rear guide bar base are arranged symmetrically, the middle ground comb is located between the front guide bar base and the rear guide bar base, the flower combs are installed on the front guide bar base and the rear guide bar base respectively, the ground combs are installed on the front guide bar base and the rear guide bar base respectively, and the middle ground comb is installed on a movable guide bar base; the guide bar mechanism further comprises an eccentric wheel connecting rod transmission mechanism, and the movable guide bar base and the middle ground comb are driven by the eccentric wheel connecting rod transmission mechanism to do horizontal reciprocating transverse motion between the front knockover needle and the rear knockover needle. The adjustment ranges of the stroke of the middle ground comb and the knockover spacing are large, and the middle guide bar transmission mechanism is simplified.

Description

technical field [0001] The invention relates to a knitting mechanism of a warp knitting machine, in particular to a knitting mechanism of a double needle bed warp knitting machine. Background technique [0002] The knitting mechanism of the existing double-needle bed warp knitting machine includes a knitting mechanism and a bar mechanism; Needle, symmetrically arranged front sinker and rear sinker, and symmetrically arranged front knitting main shaft and rear knitting main shaft. , a number of ground combs, and a middle ground comb between the front bar seat and the rear bar seat, the front bar seat and the rear bar seat are fixedly connected to the warp knitting machine frame respectively, so The several flower combs are installed on the front comb seat and the rear comb seat respectively, the ground combs are respectively installed on the front comb seat and the rear comb seat, and the middle ground comb is installed on the On a movable comb seat, the movable comb seat i...

AI Technical Summary

Problems solved by technology

[0003] The knitting mechanism of this structure has the following two defects in its work: on the one hand, due to the limitation of the size of the oil tank and the stroke of the cam, the swing stroke of the middle comb is limited, thus affecting the front and rear detachment of the double needle bed. The knock-off distance between loop needles is the length of the yarn on the double-needle bed fabric; on the other hand, the adjustment range of the knock-off distance of the knitting mechanism is small. For the knock-off distance greater than 30mm, this mechanism needs to replace the The cam is cumbersome to replace, which greatly increases the production cost
