Raschel jacquard warp knitting machine with adjustable tension

Abstract

The invention discloses a Raschel jacquard warp knitting machine with adjustable tension. The Raschel jacquard warp knitting machine comprises a warp knitting machine body, a warp feeding box is arranged at the top of the warp knitting machine body, a supporting frame is fixedly installed at the top of the warp feeding box, a warp shaft is movably installed on the supporting frame, a feeding port is formed in the top of the warp feeding box and located under the warp shaft, a discharging port is formed in the bottom of the warp feeding box, and fixed plates are fixedly installed on the two sides of the inner wall of the warp feeding box respectively. By arranging a tension adjusting mechanism, the tension of yarns made from different materials can be adjusted; by rotating an adjusting wheel, a tension wheel moves; when the tension wheel moves, the tension can be adjusted through cooperation between a pressing roll I and a pressing roll II, in this way, it is avoided that in a warp knitting machine, patterns on cloth are effected by breakage of yarns, and work of the warp knitting machine is affected, and it can be further avoided that because the tension is not sufficient, the yarns become loosened, and then the quality of the patterns on the clothe is affected.

Description

technical field [0001] The invention relates to the technical field of warp knitting machines, in particular to a Raschel jacquard warp knitting machine with adjustable tension. Background technique [0002] The warp knitting machine refers to the use of one or several groups of yarns arranged in parallel to feed all the working needles of the machine and form a loop at the same time to form a knitted fabric. This method is called warp knitting, and the fabric is called warp knitted fabric. The machine that finishes this kind of warp knitting is called warp knitting machine. [0003] Raschel lace is produced by the Raschel multi-bar warp knitting machine, which currently has a maximum of 78 bars. The more bars, the larger the space for pattern design. Multi-comb raschel lace is favored by consumers because of its high production efficiency, exquisite pattern and high degree of production automation. Jacquard raschel lace is produced by raschel warp knitting machines equippe...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a tension-adjustable Raschel jacquard machine, which has the advantages of stable warp let-off, and solves the problem that the Jacquard Raschel lace warp knitting machine mentioned in the background technology is working. The yarn is input to the knitting mechanism through the let-off mechanism of the tension rod, but the tension of the existing Jacquard Raschel warp knitting machine cannot be adjusted during the let-off, resulting in the problem that the yarn is prone to breakage
