[0026] Reference Figures 1 to 2 The woven fabric winding device of this utility model is illustrated in the following embodiments:

[0027] In some embodiments, the woven fabric winding device includes a base 100, two friction rollers 200, a drive unit, a support assembly 300, a roll shaft 400, and at least one guide roller 500.

[0028] Two friction rollers 200 are arranged in parallel and symmetrically within the base 100. The two friction rollers 200 are rotatably connected to the base 100 through a rotating bearing. The base 100 provides rotational support for the friction rollers 200. The rotating bearing improves rotational stability. There is a gap between the two friction rollers 200 to reduce mutual interference and prevent contact between the two friction rollers 200, thus avoiding interference with normal rotation.

[0029] The support assembly 300 includes two support seats 300 and a mounting bracket 310. The two support seats 300 are used to mount the fabric roll shaft 400, and the mounting bracket 310 is used to rotatably mount the guide roller 500 and other components. The two support seats 300 are located above the base 100, and the support seats 300 span the two friction rollers 200. The support seats 300 are provided with vertically extending limiting grooves 320. The opening of the limiting grooves 320 is provided with a retaining edge to prevent the end of the fabric roll shaft 400 from disengaging from the limiting grooves 320. The fabric roll shaft 400 is parallel to the friction rollers 200, and both ends of the fabric roll shaft 400 are respectively embedded in... Within the two limiting grooves 320, the fabric winding shaft 400 is positioned above the two friction rollers 200. During the winding process, the diameter of the fabric winding shaft 400 continuously increases as it winds the woven fabric, causing it to move upward relative to the limiting grooves 320. Simultaneously, the outer diameter of the fabric winding shaft 400 rotates with the two friction rollers 200, thereby driving the fabric winding shaft 400 to rotate and continue winding the woven fabric. The drive unit is connected to one of the friction rollers 200, driving the friction roller 200 to rotate. The drive unit can be any type of motor, and the motor and the friction roller 200 can be connected via various transmission structures, such as gear structures and pulley structures.

[0030] Woven fabric, also known as machine-woven fabric, is a sheet-like fabric made of two or more sets of parallel yarns or filament bundles that interweave perpendicularly at a certain angle and according to a specific pattern. Because the interlacing of the yarns forms a stable structure, the yarns have a certain degree of elasticity during the manufacturing process. Due to tension, the yarns will shrink inward, resulting in problems such as curled edges and wrinkles in the rolled-up fabric. To address this problem, this invention designs guide rollers 500. There are three guide rollers 500, all rotatably mounted on the mounting frame 310. The guide rollers 500 are parallel to the fabric winding shaft 400. One guide roller 500 is located behind the take-up roller of the fabric winding shaft 400, i.e., at the fabric inlet of the fabric winding shaft 400. Two guide rollers 500 are positioned at the upper rear. The woven fabric passes sequentially through the upper guide roller 500 and the guide roller 500 behind the take-up roller before entering the fabric winding shaft 400 for winding. Each guide roller 500 has multiple guide ridges 510 spirally arranged. These guide ridges 510 are mirror-symmetrically distributed about the center line of the guide roller 500's cross-section. Figure 2 As shown, when passing through the guide roller 500, the convex strip guides the woven fabric to unfold to both sides, causing the woven fabric to be subjected to tension pulling to the left and right sides, making the woven fabric flatter and less prone to curling. The helix angle θ of the guide convex strip 510 satisfies: 0° < θ ≤ 25°, which provides a better guiding effect.

[0031] When started, the woven fabric is located between the friction roller 200 and the guide roller 500. The drive unit drives one of the friction rollers 200 to rotate, so that the woven fabric passes through the guide roller 500 in sequence and finally wraps around the roll shaft 400. The guide roller 500 is symmetrically provided with guide protrusions 510 spirally arranged around the guide roller 500. The guide protrusions 510 make the woven fabric subject to tension pulling to the left and right sides when passing through the guide roller 500, making the woven fabric flatter and less prone to curling.

[0032] To maintain the elastic force between the woven fabric and the friction roller 200, a pressure roller (not shown in the figure) is also provided. The pressure rollers are parallel to the friction roller 200, and both ends of each pressure roller are embedded in the two limiting grooves 320. The pressure rollers are located on the upper side of the fabric roll shaft 400, and can press down on the fabric roll shaft 400 by their own weight. In some other embodiments, a rotating frame can also be provided, rotatably mounted on the mounting frame 310. The pressure rollers are rotatably mounted on the rotating frame. Moving the rotating frame moves the pressure rollers onto the fabric roll shaft 400, while the rotating frame also serves to limit movement and apply pressure. Both ends of the fabric roll shaft 400 and the pressure rollers are provided with rotating bearings, which are located in the limiting grooves 320.

[0033] To accommodate fabric rolls 400 of varying lengths, the support base 300 is designed to be adjustable along the axial direction of the fabric roll 400 on the base 100. Since the width of the woven fabric varies, the length of the fabric roll 400 also varies; therefore, this design allows for flexible adjustment of the position of the support base 300 to match fabric rolls 400 of different lengths.

[0034] Fixing structures 600 are provided on both sides of the support base 300 located on the friction roller 200. These structures are used to securely fix the support base 300 to the base 100.

[0035] To enhance stability during sliding, slide rails 110 are provided on both the front and rear sides of the base 100. Correspondingly, sliders 330 are installed on both sides of the support 300, which can slide on the slide rails 110 respectively. The slide rails 110 adopt a dovetail groove structure, and the sliders 330 are embedded with ball bearings to form a low-friction sliding pair, realizing stepless adjustment of the support 300 along the axial stroke of ±150mm. In some other embodiments, a polyurethane damping layer with a thickness of 0.5mm is added to the contact surface between the support 300 and the slide rails 110. The locking bolt adopts a stepped thread design, with the front section being an M8×1.25 fine thread and the rear section having anti-loosening teeth to ensure that the locking torque is stable within the range of 5-6 N·m, ensuring both fixing strength and preventing deformation of the slide rails 110.

[0036] To further ensure that the support base 300 is firmly fixed after sliding to the desired position, fixing structures 600 are provided on both slide rails 110. These fixing structures 600 consist of fixing screws 610 and screw holes. Specifically, screw holes are opened on the top of the slider 330, through which the fixing screws 610 can pass and abut against the slide rail 110, thereby reliably fixing the support base 300 to the base 100.

[0037] In some other embodiments, the fixing structure 600 includes fixing screws 610, a plurality of screw holes and fixing holes. The plurality of screw holes are spaced apart along the length of the base 100, and the fixing holes are located on the base 100. The fixing screws 610 pass through the fixing holes and screw holes in sequence to fix the support 300 to the base 100. The plurality of screw holes are spaced apart along the length of the base 100, providing multiple potential fixing positions for the support 300.

[0038] The design of the mounting hole as an oblong shape indicates that it has a certain length, allowing for positional adjustment within a certain range. When it is necessary to fix the support 300, the fixing screw 610 passes through the mounting hole and the selected screw hole in sequence, thereby firmly fixing the support 300 to the base 100. The oblong mounting hole allows for fine-tuning of the position of the support 300 after the fabric roll 400 is in place. This allows for precise adjustment of the support 300 according to the actual length of the fabric roll 400 and support requirements, achieving a better support effect.

[0039] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
