Synchronous driving anti-sliding yarn-guiding device

Abstract

The invention discloses a synchronous driving anti-sliding yarn-guiding device. The synchronous driving anti-sliding yarn-guiding device comprises a guide rail which is arranged along left and right direction; a rack which is parallel to a slide rail is fixed on the slide rail; yarn guide positioning blocks are respectively arranged at the two ends of the slide rail; a yarn guide is arranged between the two yarn guide positioning blocks; the main body of the yarn guide is in sliding connection with the slide rail through a slide block; a yarn guide opening and a rectangular chamber are formed on the main body; a first opening is formed on a middle part of the upper end of the rectangular chamber; the yarn guide opening is communicated with the rectangular chamber through the first opening; a driving rod is arranged above the yarn guide opening; the driving rod comprises a left and right moving sleeve and an inserting element which is ecstatically sleeved in the sleeve; the inserting element is arranged in the yarn guide opening; a synchronous driving device is arranged in the rectangular chamber; a synchronous gear of the synchronous driving device is meshed with the rack. The synchronous driving anti-sliding yarn-guiding device can drive the yarn guide and the driving rod to synchronously move by the synchronous driving device, so that the driving rod can be prevented from separating from the yarn guide.

Description

[0001] Technical field: [0002] The invention relates to the technical field of textile machinery, in particular to a yarn guide device. [0003] Background technique: [0004] In the process of flat knitting machine, the drive pin on the head of the yarn guide moves in parallel. In order to prevent the yarn guide from slipping out of the guide rail and to meet the requirements of weaving different fabric widths on the same machine, a limit device must be used to limit the yarn guide. The moving stroke of the yarn guide makes it stop at the edge of the fabric and ensures that the yarn guide re-enters the working position when the yarn guide changes direction. [0005] The prior art generally adopts the following technical solution: a groove is provided on the yarn guide for the drive pin to extend, the drive pin can move up and down under the action of an elastic member, and the drive pin extends into the yarn guide The grooves in turn drive the yarn guide to move along the guide rai...

Problems solved by technology

[0006] Although the above-mentioned technical solution can prevent the yarn guide from slipping out of the guide rail and meet the requirement of weaving different fabric widths on the same machine, the drive pin may accidentally slip out of the yarn guide during work because The groove on the yarn guide has two slopes. The slope of the slope, the weight of the yarn guide itself, and the speed of the drive pin may cause the drive pin to accidentally break away from the yarn guide during the process of driving the yarn guide. device, thereby affecting the normal operation of the yarn guide
