Warp knitting machine of two-needle bar

Abstract

The invention discloses a warp knitting machine of a two-needle bar. The warp knitting machine includes a transmission mechanism, a looping mechanism, a guide bar translating mechanism, a let-off mechanism and a traction and coiling mechanism. The warp knitting machine is characterized in that the transmission mechanism drives a connection rod mechanism through two crank shafts; the crank shafts are arranged in a front oil tank and a rear oil tank respectively; a motor drives the front crank shaft and the rear crank shaft to rotate; the crank shafts drive connection rods to transmit power to the looping mechanism; the looping mechanism includes a groove needle bed in front-and-back symmetry and a needle core bed mounted correspondingly, a fixed knocking-over sheet, a sinker and a swinging guide bar. A yarn guide needle is mounted on the swinging guide bar. According to the invention, a groove needle is adopted as a knitting needles and knitting is implemented through mutual cooperation of a needle core and the groove needle. The warp knitting machine of the two-needle bar is simple in motion role and small in stroke, and is small in vibration and noise during the machine operation process. The movement of the looping mechanism and the swinging of a guide bar are both driven by the crank shafts and no additional main shaft used for driving the guide bar is needed, so that the machine operation speed is increased.

Description

technical field [0001] The invention relates to a warp knitting machine, in particular to a double needle bed warp knitting machine, which belongs to the field of textile machinery. Background technique [0002] The transmission mechanism of the existing double-needle bed warp knitting machine adopts a cam type transmission mechanism, and its working principle is mainly to use a cam with a certain curved shape to make the loop forming parts move according to the expected law through the rotor and the connecting rod. 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 affects the running speed of the machine and is unfavorable for high-efficiency production. [0003] The double-needle bed warp knitting machine currently on the market co...

Problems solved by technology

In this way, the operating speed of the warp knitting machine is limited, and the transmission connection between the main shaft and the auxiliary shaft needs to be maintained, which affects work efficiency and increases costs.
