Description
Technical Field
The utility model relates to a winding device, in particular to a knitted fabric winding device.
Background
The knitted fabric is a fabric formed by knitting yarns with knitting needles to form loops and mutually stringing the loops. According to the difference of weaving methods, knitted fabrics are classified into weft knitted fabrics and warp knitted fabrics. Weft knitting fabrics are usually woven on various weft knitting machines by taking low-elastic polyester yarns or special-shaped polyester yarns, nylon yarns, cotton yarns, wool yarns and the like as raw materials, and adopting plain stitch, variable plain stitch, rib plain stitch, double rib plain stitch, jacquard weave, looped pile stitch and the like. Warp knitted fabrics are then looped in a longitudinal (warp) order of the fabric face with a plurality of yarns simultaneously.
The knitted fabric is widely applied to clothing fabric, lining, home textile and other products and is popular with consumers. According to different varieties, the knitted fabric can be used for the fabrics of men and women upper garment, suit, windwear, children garment and the like, and the polyester cotton knitted fabric can be used for the fabrics of shirts, jackets and sportswear. In addition, there are artificial fur needle fabrics for overcoat fabrics, clothing liners, collars, hats, and the like, velvet knitting fabrics, and the like.
After knitting, the knitted fabric is collected in a coiled manner by a coiling device so as to keep the fabric flat and the subsequent shipping. However, the knitted fabric has strong stretching capability due to the fabric forming mode, and the fabric is often deviated due to different local stretching ratios in the fabric rolling process (the fabric is often deviated to the side with larger stretching ratio in rolling). The existing deviation rectifying mode generally adopts a deviation rectifying device to push the edge of the deviated fabric back so as to enable the fabric to return to the correct position. However, the deviation rectifying mode realized by pushing the edges of the fabric only pushes the deviated fabric back, errors of different winding rates caused by inconsistent stretching rates of two sides of the fabric in the winding process are not eliminated, and if the errors are continuously accumulated, the final deviation value of the fabric exceeds the deviation rectifying range of the existing deviation rectifying device, so that the edge of the fabric is overturned in the winding process, and the winding quality is affected.

The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.
The knitted fabric winding device shown in fig. 1 to 5 comprises a deviation rectifying mechanism 300, a deviation detecting mechanism 200 and a winding mechanism 100 which are sequentially arranged along the fabric feeding direction of the knitted fabric.
As shown in fig. 1, the winding mechanism is composed of a winding shaft and a power system for driving the winding shaft to rotate. The winding shaft is driven to rotate through the power system, so that the knitted fabric is wound at a constant speed.
The deviation detecting mechanism 200 is disposed on the feeding side of the winding mechanism to detect the deviation of the two side edges of the advancing knitted fabric. Specifically, whether the edge of the knitted fabric deviates from a set boundary value is detected, and when the edge deviates from the set boundary value, the deviation detecting mechanism sends a driving signal to the deviation correcting mechanism 300 connected with an electric signal of the deviation detecting mechanism, so that the deviation correcting mechanism is driven to act and the deviated knitted fabric is corrected.
In this scheme, the deviation rectifying action performed by the deviation rectifying mechanism is not realized by pushing the edge of the deviated knitted fabric. But the deviation caused by the different expansion rates in front is smoothed by changing the cloth feeding speed and the pulling rate of the left side and the right side of the knitted fabric.
Specifically, the deviation rectifying mechanism 300 includes two sets of deviation rectifying components 310, which are centrally and symmetrically disposed on the cloth feeding side of the deviation detecting mechanism 200, and are driven by the deviation detecting mechanism when rectifying deviation, and one set of deviation rectifying components performs deviation rectifying action. It should be noted that, the deviation correcting principle of the deviation correcting component is that when the knitted fabric deviates, one group of deviation correcting components work, and the knitted fabric is clamped and rolled by the deviation correcting component, so that the fabric feeding speed and the stretching rate of the deviation side of the knitted fabric passing through the deviation correcting component are improved.
In detail, as shown in fig. 2, the deviation rectifying assembly 310 includes an upper taper roller 311 straddling the knitted fabric and a lower taper roller 316 straddling the knitted fabric. When the knitted fabric does not deviate, the knitted fabric passes between the two conical rollers without contacting with the two conical rollers. It should be noted that the lower edge of the upper cone roller and the upper edge of the lower cone roller extend horizontally, so as to ensure that the fabric can be kept horizontal when the upper cone roller and the lower cone roller approach each other and clamp the knitted fabric. In addition, two ends of the upper cone roller and the lower cone roller are respectively provided with a frame 313 fixed on the supporting surface, and a double-rod telescopic cylinder 312 is installed on the frame and is vertically arranged, so that two telescopic rods can vertically and synchronously stretch. A shaft sleeve 314 is respectively arranged on the telescopic rod end parts of the double-rod telescopic cylinder 312, and the end parts of the upper cone roller and the lower cone roller are respectively rotatably inserted in the shaft sleeve. In addition, a motor 315 is fixedly mounted on one of the sleeves and is in driving connection with the end of the upper conical roller to drive the upper conical roller to rotate as a driving roller.
As shown in fig. 3, the deviation detecting mechanism 200 includes two guide rods 210, and the two guide rods 210 are equally high and parallel and span the upper surface of the knitted fabric, and when the knitted fabric is wound, the knitted fabric horizontally slides under the two guide rods. And two pairs of proximity switches 220 are arranged between the two guide rods, the two pairs of proximity switches are symmetrically arranged on two sides of the knitted fabric in a separated mode, and the edges of the knitted fabric pass through the proximity switches when the knitted fabric is rolled. The proximity switch judges whether the knitted fabric deviates or not by detecting whether the edge of the knitted fabric moves out or not. In addition, the two sets of contact switches 220 are respectively connected with a set of deviation rectifying components 310, so as to drive the corresponding deviation rectifying components to act after detecting that the knitted fabric deviates.
In this scheme, the specific structure of the proximity switch 220 is that a bracket 223 is fixed on the supporting surface, a U-shaped block 221 is arranged at the upper end of the bracket, the notch of the U-shaped block is arranged towards the edge of the knitted fabric, and when the knitted fabric is rolled, the edge of the knitted fabric passes through the notch of the U-shaped block. Meanwhile, a proximity switch 222 is also installed on the U-shaped block, and the proximity switch is opposite to the edge of the penetrating knitted fabric and is electrically connected with the corresponding deviation rectifying component. When the edge of the knitted fabric moves out of the lower part of the proximity switch, the proximity switch is triggered and sends a driving signal to the deviation rectifying group price electrically connected with the proximity switch, so that the deviation rectifying component performs deviation rectifying operation on the knitted fabric.
In order to better adapt to the deviation detection requirements of knitted fabrics with different widths, the deviation detection requirements are required. An adjusting plate 224 is also horizontally arranged on the side of the U-shaped block 221 facing away from the knitted fabric, and the adjusting plate is inserted into the bracket in a sliding fit manner so as to adjust the interval between the two U-shaped blocks by sliding in the bracket. Meanwhile, in order to improve the alignment precision, an adjusting groove 226 extending along the length direction of the adjusting plate is further formed in the adjusting plate, and a rack 225 is arranged on one side of the adjusting groove. A hand wheel 227 is rotatably mounted on the support 223, the end of which passes through the support and is coaxially connected to an adjustment gear 228 which engages the rack. When the width of the knitted fabric needs to be adjusted, the hand wheel rotates to drive the adjusting plate to transversely move, so that the accurate adjustment of the distance between the two U-shaped blocks is realized.
The working principle is that when the knitted fabric deviates during winding, a proximity switch on the side of the knitted fabric, which deviates, is triggered, so that a deviation correcting component electrically connected with the proximity switch is driven to act, and the deviated knitted fabric is corrected. Taking fig. 4 as an example, at this time, the knitted fabric deviates leftwards due to inconsistent expansion rate in the winding process, and the deviation rectifying assembly with the upper cone roller and the lower cone roller with larger diameters at the right side end in the deviation rectifying assembly acts to apply larger traction force to the right side of the knitted fabric, so that the fabric feeding speed at the right side of the knitted fabric is increased, and finally, rightwards guiding of the knitted fabric is realized. On the contrary, as shown in fig. 5, when the knitted fabric deviates rightward, the deviation rectifying assembly with the upper cone roller and the lower cone roller with larger diameters at the left side end in the deviation rectifying assembly acts to apply larger traction force to the left side of the knitted fabric, so that the fabric feeding speed at the left side of the knitted fabric is increased, and the leftward guiding of the knitted fabric is finally realized.
In the scheme, the deviation errors of the knitted fabric are eliminated by changing the cloth feeding speeds at two sides of the deviated knitted fabric, and finally the aim of correcting the knitted fabric is fulfilled. Compared with the traditional scheme, the occurrence of the situation that the edge of the fabric is turned over due to error accumulation is greatly reduced.
Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
