Description

Fabric weft straightening and pattern straightening system

Technical Field

The utility model relates to a system for be used for correcting oblique, the curved, the crooked and flower shape bending of latitude of fabric, the style of flower specifically is a whole system of spending of weft straightening of fabric belongs to weaving equipment and technology technical field.

Background

The skew is a skew state in which the weft or knitted course deviates from a straight line perpendicular to the fabric warp or wale, and the bow (hook) is a skew state in which the weft or knitted course deviates from a straight line perpendicular to the fabric warp or wale, forming one or more arcs in the fabric width direction. The weft yarn of the utility model refers to the weft yarn of woven fabric or the course of knitted fabric.

The shuttle fabric is formed by interweaving warp yarns and weft yarns which are vertical to each other and are interwoven in a 90-degree angle, the longitudinal yarns are called warp yarns, the transverse yarns are called weft yarns, and in most cases, the weft yarns slide and deviate from a skew state formed by being vertical to the warp yarns of the fabric and are called weft skew. The weft yarn bending deflection correction of the woven fabric is to enable each weft yarn of the weft deflection to be deviated from a state vertical to warp yarns through the mechanical action of the existing weft straightening device, and to restore the vertical intersection of the weft yarn and the warp yarns in the whole width.

Knitted fabrics are fabrics formed by sequentially bending yarns into loops, and interlooping all the loops with each other, and are classified into warp knitted fabrics and weft knitted fabrics according to the process of forming the loops by the yarns. The bias/skew of the knitted fabric is the deviation of the stitches from a straight line perpendicular to the wales of the fabric, i.e. the courses of the knitted fabric are connected in series leaving a state of equilibrium, unlike the migration of each yarn with the woven fabric. Therefore, for correcting the state of the wale bias of the knitted fabric, it is only necessary to apply mechanical correction to the starting position of the course bias of the knitted fabric so as to restore the state to be perpendicular to the straight line of the wale, and other stitch biases connected in series with the starting position are corrected in a smooth manner, unlike the case where the woven fabric is corrected for every weft which has deviated, which is determined by the weave structure of the knitted fabric.

In the weaving and post-finishing processes of the fabric, due to the influence of equipment precision errors, various mechanical movements and manual operation, weft skew, weft bending, warp bending and pattern bending are often generated to influence the subsequent processing, so that the quality of finished fabrics is influenced, the use value of textiles is reduced, and the weft yarn distortion is corrected by using a weft straightening device. The existing weft straightening device mainly comprises a pinwheel weft straightening device and a roller weft straightening device.

The pinwheel weft straightening device is a passive weft straightening device, two sides of the fabric needing weft straightening in the radial direction are nailed on the outer circumferential surfaces of a left pinwheel and a right pinwheel, and the pinwheels are in a completely free rotating state. In the process that the pinwheels rotate, the splayed arrangement of the two pinwheels provides warp component force and weft component force for the fabric, the weft component force corrects weft bending of the fabric, the warp component force provides rotating torque for the pinwheels, so that the pinwheels at the lagging ends of the weft skew accelerate, the pinwheels at the leading ends of the weft skew decelerate, and the weft skew of the fabric is corrected.

Therefore, to improve the weft straightening effect of the fabric, the inclination of the pin wheel needs to be increased to increase the fabric spreading amount, but the subsequent problems are that the too large spreading of the pin wheel causes the defects of edge breakage, too large pin holes, printing white edges and the like, and some fabric after-finishing processes need to control the spreading amount, so that the weft straightening effect is limited by the allowable maximum spreading amount of the fabric.

The key of the pin wheel weft straightening is that the warp direction of the fabric is required to be kept in a loose state, if the warp direction tension of the fabric is too large, the speed difference between two pin wheels is reduced, the weft straightening effect is extremely poor, loose cloth feeding is required, and the problem brought by the loose cloth feeding is that the fabric is easy to deckle, and the fabric is broken by deckle from the pin wheels. The edge suction device is prevented from being installed at the edge of the fabric, the warp tension of the fabric is too large, the weft straightening effect is greatly reduced, and the weft straightening effect is influenced by the warp tension of the fabric.

The pin wheel weft straightening is realized by recovering the internal force of the fabric, a certain time is required from the pin wheel insertion to the pin wheel withdrawal of the fabric, and the pin wheel weft straightening effect is limited by the running speed of the fabric. In addition, when the fabric leaves the pinwheel, that is, when the fabric is subjected to a needle miss, a certain weft bending is generated, and high-precision weft straightening cannot be realized.

The pinwheel weft straightening device has the advantages that the two pinwheels completely belong to driven bodies which can rotate freely, no driving power exists, the rotating damping torque of the pinwheels is reduced, the weft straightening effect is improved, the processing and matching part precision of the pinwheels is very strict, the diameter of the pinwheels is usually 500-1000 mm, the pinwheels are large in size, high in processing difficulty and high in manufacturing cost, the pinwheels are easy to break when the pinwheels are sewn, when the pinwheels cannot be repaired, the whole pinwheels are scrapped, and the pinwheel weft straightening use and maintenance cost is high.

The fabric is penetrated by the needles of the pinwheel to advance in the two sides in the width direction, when the turned edges of the cloth and the cloth are staggered in the width direction, the needles of the pinwheel are easy to deviate from the cloth edges and fall off the edges, secondly, the pinwheel penetrates the fabric, the cloth cover is easy to damage, moreover, some fabrics have sparse organizational structures, the two sides cannot be penetrated by the needles of the pinwheel to advance at all, and the conditions limit the use range of the whole weft of the pinwheel.

Adopt the whole latitude device of roll-type to correct the fabric distortion, use a plurality of correction rollers for example bend roller and straight roller to correct the fabric distortion through adjusting the fabric stroke usually, this kind of whole latitude device of roll-type is because need adjust the fabric through many correction rollers, and mechanical structure is comparatively complicated, and it is also longer to adjust the stroke, belongs to the system of great time delay, and the response is slow, is unfavorable for real-time correction control.

If the width of the fabric is smaller than the working width of the correcting roller, the correcting efficiency is correspondingly reduced, and the fabric entering the roller type weft straightening device is required to be in a good centered state, otherwise, the bending roller can multiply and enlarge the deformation degree. For knitted fabrics which have high extensibility and are easy to deform under external force, chiffon fabrics which have loose structures and low-elasticity woven fabrics, the knitted fabrics and the low-elasticity woven fabrics are easy to generate elasticity due to the structures of the knitted fabrics and can still return to the original deformation state even after being straightened by a straightening roller.

In addition, when the fabric is in weft skew/weft bending, the angle of the correcting roller is adjusted to increase the distance of the fabric at the part of the skew/weft bending so as to improve the weft skew/weft bending of the fabric. For the non-elastic fabric, after the angle of the correcting roller is adjusted, the full-width inward fabric does not completely cover the correcting roller any more, the fabric is suspended, and the weft skew/weft bend cannot be corrected at all, so that the non-elastic fabric cannot be corrected at all by the correcting roller.

For high-elasticity fabrics, the straightening roller or the pin wheel does not have enough weft straightening strength, the straightened fabric weft yarn is easy to restore to the original shape, and both cannot effectively improve weft skew/weft bending.

In conclusion, the pin wheel weft straightening device and the roller weft straightening device have the defects of complex structure, long adjusting stroke, poor weft straightening effect, limited applicable textile types and the like. Therefore, the rapid development of textiles, the updating of fabric fibers and weaving technologies, and the unreasonable bending of fabrics cannot meet the requirements of correcting skew weft, warp weft and skew pattern bending by using the existing technologies, so that a novel weft straightening and pattern straightening measure is urgently needed to solve the existing dilemma, reproduce the pattern, grain, style and basic organization structure of the textile surface, improve the use value of the textile and improve the product quality.
