Description

Correcting assembly and correcting device

Technical Field

The utility model relates to a technical field is corrected to the fabric, concretely relates to correct subassembly and orthotic devices.

Background

In weaving and finishing processes of the fabrics, problems of skew, warp, skew pattern, warp pattern and the like are frequently generated due to the influence of equipment precision errors, various mechanical movements and manual operation, wherein the skew is a skew state formed by a weft yarn or a knitted fabric row deviating from a straight line vertical to a warp yarn or a wale of the fabrics, the warp (bow weft) is a state that the weft yarn or the knitted fabric row deviates from a straight line vertical to the warp yarn or the wale of the fabrics and forms one or more arc skew states in the width direction of the fabrics, and the weft yarn refers to the weft yarn or the knitted fabric row of the woven fabrics. The problems can influence subsequent processing, so that the quality of finished fabrics is influenced, and the use value of textiles is reduced. Therefore, the weft yarn distortion needs to be corrected by using the 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 of rotation of the pinwheel, the splayed arrangement of the two pinwheels provides warp and weft component forces for the fabric, the weft component force corrects weft bending of the fabric, the warp component force provides a rotation moment for the pinwheel, so that the pinwheel at the lag end of the skewing is accelerated, and the pinwheel at the leading end of the skewing is decelerated, thereby correcting the skewing of the fabric.

For a pinwheel weft straightening device, the pinwheel weft straightening device has a certain weft straightening effect, but the pinwheel weft straightening device still has the following defects:

1. in order to improve the weft straightening effect of the fabric, the inclination of a pin wheel is required to be increased, and the fabric expanding amount is increased, but the problems are that the edge breaking, the too large pin hole, the printing white edge and the like are caused by the too large expanding of the pin wheel; moreover, the after-finishing process of some fabrics needs to control the spreading of the fabrics, which is opposite to the fact that the widening of the fabrics needs to be increased in the pin wheel weft straightening, so that the weft straightening effect is limited by the maximum allowable spreading of the fabrics.

2. 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 can be installed for preventing edge dropping, but the installation of the edge suction device can cause the warp tension of the fabric to be overlarge so as to greatly reduce the weft straightening effect, and the weft straightening effect is influenced by the warp tension of the fabric.

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

4. The radial partial skewing of the fabric and the partial skewing with small inclination degree can not be corrected because the two pinwheels of the pinwheel weft straightening device are arranged in a splayed shape, and under the condition that the warp direction component force provided by the fabric to the pinwheels is too small, the rotating moment can not be provided for the pinwheels, so that the pinwheels at the lag end of the skewing are accelerated, and the pinwheels at the leading end of the skewing are decelerated.

5. The pinwheel weft straightening device has the advantages that the two pinwheels completely belong to the driven body which can rotate freely, no active power is provided, 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 larger than 500-1000 mm, the pinwheels are large in size, large in processing difficulty and high in manufacturing cost. When the pinwheel passes through the sewing head, the needle of the pinwheel is easy to break, and when the pinwheel cannot be repaired, the whole pinwheel is scrapped, and the pinwheel is high in maintenance cost for weft finishing. The two sides of the fabric in the width direction are penetrated by the needles of the pinwheel to advance, and when the edges of the cloth are curled and the cloth is staggered in the width direction, the needles of the pinwheel are easy to deviate from the cloth edges to cause edge shedding; in addition, the needle wheel punctures fabrics, and the cloth cover is very easy to damage, moreover, some fabrics have sparse organizational structure, and the radial two sides of the fabrics can not be punctured by the needle of the needle wheel at all to advance, and the conditions all limit the application range of the needle wheel for weft straightening.

The roller type weft straightening device uses a plurality of correcting rollers, for example, a bending roller and a straight roller correct the fabric distortion by adjusting the fabric stroke, and the roller type weft straightening device is relatively complex in mechanical structure and relatively long in adjusting stroke due to the fact that the fabric needs to be adjusted by a plurality of correcting rollers, belongs to a system with large delay, is slow in response and is not beneficial to real-time control. The roller type weft straightening device is formed by adjusting a full-width fabric through a bending roller and a straight roller, and the roller type weft straightening device cannot perform local correction on the condition that local weft inclination exists in the fabric, such as a falling angle.

The roller type weft straightening device is used for straightening weft, if the width of a fabric is smaller than the working width of the straightening roller, the straightening efficiency is correspondingly reduced, moreover, the fabric enters the roller type weft straightening device and must be in a good centered state, otherwise, the bending roller can multiply increase the deformation degree, and the reaction is realized. For knitwear with large extensibility and easy deformation by external force, chiffon with loose structure and low elastic woven fabrics, the fabrics are easy to generate elasticity due to the structure and can still return to the original deformation state even after being straightened by a correcting roller.

In addition, when the fabric is in skewing/bending, the skewing/bending of the weft is improved by adjusting the angle of the correcting roller and increasing the path of the fabric at the skewing/bending part. For the inelastic 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 skew/warp of weft can not be corrected at all, so that the inelastic fabric can not be used for weft straightening at all.

For elastic fabrics, the straightening roller and the pinwheel do not have enough weft straightening strength, the straightened fabric weft yarn is easy to restore to the original shape, and both cannot effectively improve the weft skew/weft bending. The roller type correction is to change the relative running speed of the radial warp yarns through the correction deviation of a straight rod, and for elastic fabrics, the correction method cannot necessarily bring a good correction effect; for the pin wheel, the elastic fabric expands on the two pin wheels arranged in the shape of the Chinese character 'ba', and not necessarily can obtain enough warp direction component force, which is not enough to provide the rotation moment for the pin wheels to change the rotation speed of the two pin wheels, so as to achieve the function of correcting the skewness of the weft.

In addition, the fabric may have irregular, irregular and periodically varying local skews that cannot be corrected by prior art weft straightening devices.

In addition, in some special fabrics, the straightening device in the prior art cannot perform straightening, for example, in chiffon fabrics, large weft skew is easy to generate, the straightening of the prior straightening device is difficult, the straightening amount of the prior straightening device is limited, a plurality of straightening devices are required to be combined for straightening, and the prior straightening device is large in size and high in cost.

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 cause that the existing weft straightening technology cannot meet the correction of oblique weft bending and oblique pattern bending, and a novel weft straightening measure is urgently needed to solve the existing dilemma, reproduce the patterns, lines and styles on the surfaces of the textiles and the basic organizational structure, improve the use value of the textiles and improve the product quality.

By means of research utility models, it has been found that woven and knitted fabrics are suitable for different correction methods due to their different properties.

Specifically, fig. 1 shows the structure of the woven fabric of the present invention, most woven fabrics are fabrics formed by warp and weft yarns interwoven at a certain angle (e.g., 90 degrees), the longitudinal yarns are called warp yarns, the transverse yarns are called weft yarns, and in most cases, the interwoven points of the weft yarns and the warp yarns slide to generate skewness. The skew correction of the shuttle fabric in the prior art is usually corrected by the mechanical action of a weft straightening device, but the existing weft straightening device only obtains the effect that the weft with skew returns to the original interweaving point.

Fig. 2 shows the structure of the warp knitted fabric of the present invention, and fig. 3 shows the structure of the weft knitted fabric of the present invention, which is formed by sequentially bending the yarns into loops, and all the loops are interlooped with each other to form a fabric, and the process of forming the loops by the yarns is divided into a warp knitted fabric and a weft knitted fabric. 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 row stitch skewness of the non-tight chemical fiber knitted fabric, the position of the row stitch skewness of the knitted fabric can be corrected by only applying mechanical correction to the position of the stitch skewness state to restore the state to be vertical to the straight line of the wale of the fabric, and other stitch skewness connected with the position of the stitch skewness in series can also be corrected smoothly, which is different from the condition that the shuttle fabric needs to correct each deviated weft yarn, and the correction is determined by the weave structure of the knitted fabric. However, the conventional weft straightening device cannot correct the weft at a certain weft skew position, so that the weft skew correction for the fabrics is difficult.

That is, the weft straightening device in the prior art is only suitable for straightening of the normal woven fabric but is not well suitable for straightening of the knitted fabric. In order to be able to adapt to the weft straightening of woven and knitted fabrics simultaneously, the embodiment provides a straightening assembly and a straightening device.

It should be noted that the utility model discloses a rectification subassembly and orthotic devices all have obvious correction effect to big oblique shuttle fabric of latitude and knitting.

According to the correction method, the correction module is dynamically controlled to realize dynamic correction of the fabrics, so that the accuracy of fabric correction can be improved; the weft skew and/or pattern skew of the fabric can be adjusted and corrected at one time by clamping and increasing and decreasing the conveying amount of the fabric in the radial direction, so that the weft of the fabric is perpendicular to the warp of the fabric. Compared with other correction methods in the prior art, the correction method of the embodiment is more direct and has high efficiency.
