[0004] Although the above-mentioned device can perform deviation correction operations on the rolled elastic fabric, it is not convenient for the above-mentioned device to perform pre-correction adjustment according to the tension of different parts of the elastic fabric, thereby reducing the subsequent practical performance of the device. At the same time, the above-mentioned device is not convenient for quickly positioning and unloading the winding roller, thereby reducing the convenience of the device.

At the same time, two groups of slot-type photoelectric sensors can also perform real-time detection and feedback on the conveying spacing of the elastic fabric. The dual correction structure effectively improves the accuracy and stability of the equipment in winding and correcting the elastic fabric.

[0019] 2. When the present invention automatically unloads the winding guide roller that has been wound, the standard cylinder can drive the alignment card seat to move downward, so that the two sets of limit card plates can release the limit on the winding guide roller.

[0038] The regulating device 23 includes a limit card seat 232, a ball slide seat 231 is arranged on the side of the upper end surface of the limit card seat 232, and a feed guide groove 234 is opened at the center of the side end surface of the limit card seat 232, and a slot-type photoelectric sensor 233 is arranged on the inner end surface of the limit card seat 232 near the feed guide groove 234.

[0039] The limiting device 4 includes a fixed base 46, a standard cylinder 47 is fixedly arranged at the center of the inner end surface of the fixed base 46, and an alignment clamping seat 45 is fixedly arranged on the upper end surface of the standard cylinder 47, a transmission motor 41 is fixedly arranged at the center of the side end surface of the alignment clamping seat 45, and a bidirectional screw rod 43 is fixedly arranged at the output end of the transmission motor 41, the inner end surface of the alignment clamping seat 45 is threadedly connected with two groups of threaded guide seats 44 through the bidirectional screw rod 43, and a limiting clamping plate 42 is fixedly arranged at the center of the upper end surface of the threaded guide seat 44.

[0040] The material guide push plate 10 is directly opposite to the winding guide roller 1 , and the inner wall of the material guide push plate 10 does not contact the transmission card shaft 3 , which can effectively improve the stability of the subsequent mini cylinder 9 unloading the winding guide roller 1 through the material guide push plate 10 .

[0041] The upper and lower sets of guide rollers 27 on the same side are meshed and connected via a transmission gear 26. The top of the sensing guide wheel 210 is higher than the output plane of the two sets of guide rollers 27 for the elastic fabric. The sensing guide wheel 210 is higher than the elastic fabric output surface of the guide rollers 27. When the elastic fabric is conveyed, an elastic force is generated on the sensing guide wheel 210 to press down, thereby improving the stability of subsequent detection of the elastic fabric.

[0042] The limit card seat 232 is adapted to the positioning screw 24 through the ball slide 231 and then threadedly slidably connected to the inner end surface of the support card seat 21. The groove-type photoelectric sensor 233 is directly opposite to the output plane of the two sets of guide rollers 27. The groove-type photoelectric sensor 233 can perform real-time detection of the side edge of the elastic fabric introduced by the feed guide groove 234, thereby improving the early warning and judgment performance when the elastic fabric is offset. At the same time, the threaded connection between the ball slide 231 and the positioning screw 24 can also facilitate subsequent staff to adjust the offset elastic fabric through the limit card seat 232.

[0043] The lower end surface of the alignment card seat 45 is provided with two groups of guide sliding shafts, and the upper end surface of the fixed base 46 is provided with two groups of fixed shaft sleeves. The alignment card seat 45 is adapted to the guide sliding shafts and the guide shaft sleeves and then slidably connected to the upper end surface of the fixed base 46. When guiding the alignment card seat 45, the guide sliding shafts and the fixed shaft sleeves can provide sufficient limiting basis for the excessive depth of the alignment card seat 45, thereby improving the stability of the displacement of the alignment card seat 45.

[0044] Working principle: Before use, the staff can pass the elastic fabric to be rolled up between the two sets of guide rollers 27, and then guide it to the outside of the winding guide roller 1. Before the winding guide roller 1 rolls up the elastic fabric, the staff can start the standard cylinder 47. At this time, the standard cylinder 47 can drive the alignment card seat 45 to lift up the upper part of the fixed base 46 as a whole. Then the alignment card seat 45 can drive the two sets of threaded guide seats 44 to lift up synchronously. When the threaded guide seats 44 are lifted to both sides of the winding guide roller 1, the staff can start the transmission motor 41. The transmission motor 41 can drive the bidirectional screw 43 to rotate, and the bidirectional screw 43 can synchronously drive the two sets of limit card plates 42 to move centripetally through the two sets of threaded guide seats 44, so that the two sets of limit card plates 42 can synchronously limit the two sides of the winding guide roller 1 to prevent the subsequent winding guide roller 1 from deviating when rotating at a high speed, affecting the efficiency of subsequent winding. When the elastic fabric is wound, the servo motor 7 can drive the internal synchronous pulley 12 to rotate, and the synchronous pulley 12 can drive another set of synchronous pulleys through the synchronous belt 8. The pulley 12 and the transmission card shaft 3 rotate synchronously, so that the transmission card shaft 3 can drive the winding guide roller 1 to rotate at a high speed, thereby winding the elastic fabric. When the elastic fabric is wound, the stepper motor 22 can synchronously drive the guide roller 27 to rotate. The two sets of guide rollers 27 on the same side can rotate in opposite directions through the transmission gear 26, thereby synchronously conveying the elastic fabric. Since there is a speed difference between the stepper motor 22 and the servo motor 7, the elastic fabric has a relatively stable tension between the guide roller 27 and the winding guide roller 1. At this time, the multiple sets of inductive guide wheels 210 can guide and support the bottom of the rolled elastic fabric. When the pressure indication fed back to the pressure sensing module 29 by the multiple sets of inductive guide wheels 210 through the spring clamping shaft 28 changes significantly, the elastic fabric is rolled up at this time. At the same time, the two sets of slot-type photoelectric sensors 233 can perform secondary detection on the guided elastic fabric, and then locate the direction of deviation. Subsequently, the reduction motor 25 can drive the limit clamps 232 on both sides through the positioning screw rod 24 to correct and limit the elastic fabric, thereby improving the stability of winding.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
