Abstract
A warp let-off device of a stitch-knitting machine comprises a splitting plate, a roller and supports; the roller is used for performing warp let-off; the supports are used for supporting the bilateral sides of the roller respectively; the roller is in rotating connection with the supports; the splitting plate is arranged in front of the roller correspondingly; the roller is driven by a driving device to rotate; the surface of the roller is formed by nitrile rubber; the Shore hardness of the nitrile rubber of the surface of the roller is between 60 A to 85 A, the average roughness Rz of the nitrile rubber of the surface of the roller is 0.2 to 0.7 microns, the maximum roughness Rmax of the nitrile rubber of the surface of the roller is between 0.6 to 0.8 microns, and the thickness of the nitrile rubber of the surface of the roller is larger than 4.5 mm. According to the warp let-off device of the stitch-knitting machine, the usual design thought is deviated, the materials of the surface of the roller are changed, the surface hardness and the surface roughness of the roller are controlled, and accordingly the warp let-off is smooth and the knitting quality is ideal.
Description
Technical field
The utility model relates to the let-off motion of knit-stitch machine, particularly a kind of knit-stitch machine let-off motion.
Background technology
With one group or several groups yarn being arranged in parallel, on the working needle of warp-wise feeding machine, the lopping simultaneously and method that forms knitted fabric is called through compiling, this knitted fabric is called tricot, and the machine that completes this braiding process is called warp knitting machine.Warp knitting machine divides tricot warp knitting machine, elasticity Raschel looms, multi-bar raschel machine, crochet machine, knit-stitch machine etc. according to the architectural feature of machine, operation principle and purposes.Wherein knit-stitch machine is when braided fabric, and yarn is the separating needle in coiled hair, roller, yarn tension adjusting mechanism, cord roller and tension piece successively, finally arrives the yarn looping mechanism consisting of parts such as sley bar and latch needles, thereby completes the warp let-off and knitting.
Such let-off motion is in being applied to the warp knit of glass fibre, because glass fibre is different from common textile line, have its particularity, for example glass fibre belongs to fragile material, and ABRASION RESISTANCE is poor, therefore, normally adopt common ganoid roller, but in actual production process, this roller often makes glass fibre skid, thereby cannot drive organizine to advance, cause and can not weave normally.Based on this reason, existing way is to cover one deck sand paper at surface of roller, to increase the coefficient of friction of roller and glass fibre.But because glass fibre is crisp, wear no resistance, sand paper easily makes even fracture of originally ganoid glass fibre fluffing.If glass fibre fluffing, must reduce the tensile strength of glass fiber warps, and the fabric being woven into by the glass fiber warps of this fluffing, its intensity is also greatly affected.In addition; glass fibre also can be usually because fluffing be ruptured; due to roller to the yarn from coiled hair output only tension force effect; when passing through a part of yarn breakage of roller, from roller, be difficult to find on the one hand, thereby affect fabric quality; even if found on the other hand; and the yarn of these fractures to be found out from the huge yarn of quantity also extremely difficultly, need to shut down and usually need to spend a few hours and just can find, thereby greatly reduced production efficiency.
Utility model content
The technical problems to be solved in the utility model is: in order to overcome existing roller or to make glass fibre fluffing, fracture, or the deficiency that glass fibre is skidded, the utility model provides a kind of knit-stitch machine let-off motion.
The utility model solves the technical scheme that its technical problem adopts: a kind of knit-stitch machine let-off motion, comprise yarn dividing plate, for the roller of the warp let-off with for supporting the bearing of roller both sides, described roller and described bearing are rotationally connected, described yarn dividing plate is arranged on the place ahead of described roller accordingly, described roller is driven and is rotated by drive unit, and described surface of roller is acrylonitrile-butadiene rubber;
The acrylonitrile-butadiene rubber hardness range of described surface of roller is shore hardness Shore A60-85A, and mean roughness Rz is 0.2um～0.7um, maximal roughness Rmax between 0.6um between 0.8um, thickness >=4.5mm.
Described yarn dividing plate is adjustable and/or adjustable with respect to the front and back horizontal range of described roller with respect to the upright position up and down of described roller.By regulating the distance of yarn dividing plate and roller, can control the contact area of glass fibre and roller, thereby go for the warp let-off of different types of glass fibre.
Described roller comprises roll body, and described roll body outer surface is coated one deck acrylonitrile-butadiene rubber layer.
Described roller is made by acrylonitrile-butadiene rubber.
The beneficial effects of the utility model are, knit-stitch machine let-off motion of the present utility model, and surface of roller is acrylonitrile-butadiene rubber, because it is with certain elasticity, can when contacting with organizine, produce small deformation, increases the contact area of glass fibre and roller; Meanwhile, control surface roughness, is conducive to avoid glass fibre to be scraped hair or rubbing crack, and the utility model adopts surface of roller roughness to belong to smooth rank, and surface does not have decorative pattern; In existing solution, only stick to the surface roughness that improves roller, although can make the warp let-off normally move, but weaving quality cannot be protected, the utility model departs from ordinary mentality of designing, changes the material of surface of roller, and controls its thickness, case hardness and surface roughness, make the warp let-off smooth and easy, and weaving quality is very good.
