Coiling apparatus for warp knitting machine fabric

Abstract

The invention discloses a rolling-up device for warp knitted fabrics. The rolling-up device comprises a first cloth roller which is rotatably arranged on a machine frame, and a fabric tension regulating mechanism; the fabric tension regulating mechanism comprises fabric guide roller mounting seats and connecting plates, an adjustable tension spring of a thread connecting pair, a first fabric guide roller, a second fabric guide roller, a sensor and an electric control device, wherein, the fabric guide roller mounting seats and the connecting plates are respectively arranged at the two sides of the machine frame, and the first fabric guide roller and the second fabric guide roller are arranged between the fabric guide roller mounting seats and are rotatably connected with the fabric guide roller mounting seats; one ends of the connecting plates are fixedly connected with the machine frame, and the other ends of the connecting plates are rotatably connected with the fabric guide roller mounting seats, the first fabric guide roller and the second fabric guide roller are respectively arranged at the upper side and the lower side of a rotating joint of the fabric guide roller mounting seats and the connecting plates, and the two ends of the adjustable tension spring are respectively connected with the upper end parts of the machine frame and the fabric guide roller mounting seats. The rolling-up device can prevent rolled fabric patterns from distortion and deformation, and the fabric tension regulating mechanism can accurately regulate the tension required by fabrics in rolling. The rolling-up device has the advantages of wide regulation range, simple and reliable structure and small occupation space.

Description

technical field [0001] The present invention relates to a coiling device for coiling a fabric fabric woven by a textile machine, in particular to a coiling device for coiling a fabric fabric knitted by a single-needle bed, double-needle bed or stitch-bonded warp knitting machine take-up device. Background technique [0002] Existing take-up devices for warp knitted fabrics, such as a Figure 5 The take-up device of the shown double-needle bed warp knitting machine comprises a first cloth roll 21, a second cloth roll 22, a third cloth roll 23 which are rotatably installed on the frame 20, placed The cloth rolling roller press roller 24 between the second and third cloth rolling rollers 22, 23, the first cloth guide roller 25, the second cloth guiding roller 26, and the fabric tension adjustment mechanism 30, the first, second and third rolls Cloth rollers 21, 22, 23 are driven to rotate by a motor through a chain transmission mechanism. The fabric tension adjustment mechanis...

AI Technical Summary

Problems solved by technology

Such a take-up device has the following disadvantages. On the one hand, since the fabric 27 is wound tightly on the cloth rolling roller 24, these fabrics have been permanently damaged before the next process. Deformation, that is, plastic deformation, causes the pattern on the fabric to be distorted, severely deformed, the elasticity of the fabric is reduced, or even broken and loses elasticity, which greatly reduces the comfort and service life of people when it is used as a clothing material. As a mosquito net , curtains, lace decorative fabrics, medical fabrics, etc.; on the other hand, because the tension of the fabric is adjusted by increasing or decreasing the weight 30-2, and the weights are For steel parts with rated weight value, when adjusting, the fabric tension is often adjusted too large or too small, it is difficult to adjust to the fabric tension
