Full-width supporting cloth device for knitting machine

Abstract

The invention provides a supporting cloth device with tensioning and deviation correcting functions, and particularly relates to a full-width supporting cloth device for a knitting machine. A driving roll, a second transition roll and a driven roll are mounted between two supports, and an adjusting screw which pushes the driven roll to move is mounted on the driven roll. A pressure roll, a supporting roll and a first transition roll are mounted between the driven roll and the second transition roll sequentially from top to bottom, and two sides of each of the pressure roll, the supporting roll and the first transition roll are both mounted on the supports which are mounted bilaterally perpendicular to the ground. Supporting cloth is wound to form a closed ring, the supporting roll is abutted against the upper ring face of the supporting cloth, and the first transition roll is abutted against the lower ring face of the supporting cloth. The driving roll is provided with at least two guide grooves, and guide rib protrusions are arranged at positions, corresponding to the guide grooves, below the supporting cloth and are embedded into the guide grooves. The full-width supporting cloth device further comprises a power mechanism, a shaft head at one end of the driving roll penetrates through the supports, a driven gear is sleeved at the end of the driving roll, a driving gear is meshed with the driven gear, and a gear shaft of the driving gear is connected with an output shaft of a servo speed reducer.

Description

Technical field [0001] The invention relates to stitch-bonding machine equipment, in particular to a cloth support device of the stitch-bonding machine. Background technique [0002] After the chopped yarn device chopped the glass fiber strands into chopped strands, the chopped strands need to be sent out of the chopped cutting mechanism, and the chopped strands are sent to the knitting mechanism to be braided with the glass fiber, so a transmission mechanism is needed to transport the chopped Yarn. Generally, such a transmission mechanism is equipped with a support cloth. The traditional support cloth is on the bracket. The ordinary bracket is static and cannot move. For the cloth support device, it needs to be tensioned and corrected to be able to Ensure transmission quality. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a cloth support device with functions of tensioning and correction. [0004] The technical solutio...

Problems solved by technology

[0002] After the chopped yarn device cuts the glass fiber precursor into short filaments, it needs to send the short filaments out of the chopping mechanism, and send the short filaments to the weaving mechanism for weaving with glass fibers, so a transmission mechanism is needed to convey the chopped strands. Yarn, generally such a transmission mechanism is equipped with a support, the traditional support is on the bracket, the ordinary bracket is static and cannot move, for the support device, it needs to be tensioned and corrected, so that it can Guaranteed transmission quality
