Linear track sliding device for flat knitting machine

Abstract

The invention relates to a linear track sliding device for a flat knitting machine, which is mainly applied to a full-automatic computer flat knitting machine. The device is characterized in that: the middle of the lower middle part of a sliding block has a T-shaped linear through groove structure, and a track is positioned in the through groove; the sliding block is provided with four annular grooves which are symmetrically distributed up and down, left and right, and a group of annular balls is arranged in each annular groove; the upper part of the track is provided with four arc surfaces, and the four arc surfaces are contacted with the four groups of annular balls; and the track is a linear track, the section of the track is transverse H-shaped, and the four arc surfaces are all positioned on the upper part of the transverse H-shape. The device is flexible and smooth to slide; the sliding block and the track are mutually tensioned, so the track is not damaged due to downward action of gravity of a machine head and the device has long service life; and the balls and the track have good lubricating performance.

Description

technical field [0001] The invention relates to a rail sliding device, in particular to a linear rail sliding device used in a flat knitting machine, which is mainly suitable for fully automatic computerized flat knitting machines and belongs to the field of textile machinery. Background technique [0002] Fully automatic computerized flat knitting knitting machine is a special equipment for knitted garment processing, and its main application method is to knit yarn into garments. During the knitting process, the head of the flat knitting machine needs to slide back and forth repeatedly, and the sliding of the head needs to be realized by the slider supported on the rail. The structure of the slider and the rail system of the fully automatic computerized flat knitting machine in the prior art is as follows: a traditional bearing is installed on the slider, the slider is clamped on the square rail, and the bearing is connected to the square rail. Rail anastomotic connection ...

AI Technical Summary

Problems solved by technology

Its defect is: because the slider is supported on the track with a certain angle, under the action of the bearing, the slider can slide flexibly on the track, but the slider with a certain angle is connected with the machine head. During the sliding process, the gravity of the machine head is downward, causing the slider to contact the track, increasing the sliding resistance and causing metal friction, causing the track to wear, and gradually forming a sliding gap and inertia, so that the balance between the machine head and the needle row plate The relationship is affected, resulting in missing needles, broken needles and defective products in the knitting process, and seriously affecting work efficiency

But it is not suitable for the sliding of the machine head, it is only suitable for the movement of the carriage, and the sliding method and sliding structure are completely different
