With the increasing market demand for diversified and personalized fabrics, and the continuous improvement of production processes' requirements for conveying accuracy and efficiency, these devices are becoming increasingly important.

[0003] Currently, existing fabric conveying devices generally suffer from the following defects: the guide rollers of most devices are fixed in position, and the wrapping length of the fabric on the guide rollers cannot be adjusted according to the fabric thickness, elasticity and other characteristics. This results in the fabric being easily torn due to excessive tension when conveying elastic fabrics, while slippage may occur due to insufficient tension when conveying heavy fabrics, affecting production continuity and product quality. Therefore, those skilled in the art have provided an adjustable-stroke fabric conveying device to solve the problems mentioned in the background art. Utility Model Content

Through a stroke adjustment component, the synchronous position adjustment of multiple guide rollers is achieved, thereby flexibly changing the fabric wrapping length to adjust the stroke. This ensures that fabrics of different thicknesses and elasticities maintain appropriate tension during conveying, avoiding tearing and slippage, and enabling the fabric to be wound flat. Furthermore, the simultaneous control of the movement of multiple guide rollers significantly saves adjustment time, effectively improving the adaptability, adjustment efficiency, and production quality of the fabric conveying device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable-stroke fabric conveying device, comprising a first fixed frame, a second fixed frame, and a plurality of guide rollers, wherein a stroke adjustment component is provided between the second fixed frame and the plurality of guide rollers, and a scale line is provided on the upper part of the inner wall of the rear end of the second fixed frame;

[0006] The stroke adjustment assembly includes a linkage box, multiple forward threaded rods and multiple reverse threaded rods.

One end of each of the two second rotating shafts 27 passes through the corresponding first fixed frame 1 and second support plate 30 and is fixedly connected to the corresponding mounting shaft 22. By controlling the rotation of the two second worm gears 29, the rotation can be achieved via the provided second worm wheels 28 and second rotating shafts 27. The corresponding mounting shaft 22 rotates, thereby causing the unwinding roller 24 and the take-up roller 25 to rotate, realizing the conveying operation. The upper ends of the two drive boxes 26 are fixedly equipped with drive motors 32. The output ends of the two drive motors 32 pass through the corresponding drive box 26 and are fixedly connected to the corresponding second worm gear 29.

Through the controller 31, the two drive motors 32 can be started simultaneously, thereby causing the corresponding second worm gear 29 to rotate.

Guide rollers 21 are rotatably connected between the two first support plates 20 and between the front and rear inner walls of the second fixed frame 2 near the lower part. The presence of guide rollers 21 facilitates the introduction and extraction of fabric.

[0035] Working principle: During conveying, the fabric is first wound in an S-shape around multiple guide rollers 3. Then, according to the fabric characteristics such as elasticity, thickness, and production efficiency requirements, the position of the multiple guide rollers 3 is adjusted by the stroke adjustment component 4, thereby changing the wrapping length of the fabric on the multiple guide rollers 3, realizing the stroke change, thus adapting to fabrics of different thicknesses and elasticities, avoiding excessive tension causing fabric tearing or insufficient tension causing slippage. Specifically, during adjustment, rotating the adjustment knob 19 causes the first worm gear 18 to rotate, which in turn causes the corresponding transmission shaft 14 to rotate via the first worm wheel 17 and the first rotating shaft 16. Then, via the second bevel gear 15 and the first bevel gear 13, multiple forward threaded rods can be rotated. Rotating the 8 and the reverse threaded rod 9 controls the guide rollers 3 at the first and third layers and the guide rollers 3 at the second and fourth layers to move in opposite directions. During this process, the position of the adjusting slider 6 can be adjusted according to the production requirements of the corresponding fabric by observing the marking line 10 and the scale line 11, thereby adjusting the position of multiple guide rollers 3 so that the corresponding fabric reaches the specified stroke, thus ensuring the smooth winding during the conveying process. Moreover, this adjustment process can simultaneously control the movement of multiple guide rollers 3, effectively saving adjustment time. After the adjustment is completed, the controller 31 can be used to start the two drive motors 32, thereby causing the unwinding roller 24 and the winding roller 25 to rotate, achieving stable conveying operation.
