Two-needle bar warp knitting machine with double swing axles and double swing arms

Abstract

The invention discloses a two-needle bar warp knitting machine with double swing axles and double swing arms. The two-needle bar warp knitting machine is capable of dividing a guide bar swing arm to two parts. The structure comprises a guide bar, the guide bar swing arms, swing axles, and swing pull rods. The guide bar is divided to two parts which are respectively installed at the front and rear guide bar swing arms. One end of each of the front and rear guide bar swing arms is respectively fixed on the front and rear swing axles correspondingly, and the other end of each of the front and rear guide bar swing arms is respectively connected with the front and rear swing pull rods correspondingly. The front and rear swing pull rods are respectively connected with crankshaft mechanisms in front and rear boxes correspondingly. The front and rear guide bar swing arms are respectively driven to be swung by the front and rear crankshaft mechanisms. The two-needle bar warp knitting machine is capable of dividing the guide bar swing arm to two independent parts, and two guide bar swing arms are respectively swung, and are not mutually interfered. The bearing pressure of the guide bar swing arm is reduced, and the swing inertia of the guide bar in the operation process is reduced. The guide bar is more stable in the knitting cycle, and the high-speed operation of a machine is convenient.

Description

technical field [0001] The invention relates to a swing arm, in particular to a double needle bed warp knitting machine with double swing shafts and double swing arms, belonging to the field of textile machinery. Background technique [0002] The double needle bed warp knitting machine is that the knitting needles of the two needle beds are aligned front and back, installed back to back, and the bar is knitted separately on the front and rear needle beds to form loops. The bar swing arm and the bar hanger of the existing double-needle bed warp knitting machine are an integral part made in one, and all the bars are installed on this integral part. It comprises a bar, a bar swing arm, a swing shaft, and a swing pull rod. All comb bars are installed on a comb swing arm, and one end of the comb swing arm is fixed on the swing shaft. The swing axis is positioned on the main beam through the bar hanger seat. The other end of the comb swing arm is connected with a swing pull rod...

AI Technical Summary

Problems solved by technology

The cam mechanism is difficult to manufacture and has low precision. There is a line (or point) contact between the cam and the follower, the pressure is strong, and it is easy to wear

Moreover, when the cam connecting rod rotates, the inertia and centrifugal force are relatively large, which will also affect the running speed of the machine, which is not conducive to high-efficiency production
