Detailed Implementation

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Examples, such as Figures 1-5 As shown, this utility model provides a weaving machine with a width adjustment device, including a fabric winding mechanism. The fabric winding mechanism includes a fabric winding transmission box 1, inside which are arranged a drive roller 2, a traction roller 3, a tension roller 4, and a winding roller 5. A drive motor 6 is arranged on the outside of the fabric winding transmission box 1. End shafts 7 are provided at both ends of the winding roller 5, and the end shafts 7 are mounted on the fabric winding transmission box 1. The shafts of the drive roller 2, traction roller 3, tension roller 4, and winding roller 5 can be driven by gear meshing or by a gear and belt. The drive motor 6 provides power to the roller assembly. The drive motor 6 drives the winding roller 5 to rotate, thus completing the fabric winding action. The end shafts 7 can be axially keyed to the winding roller 5 for easy replacement of the winding roller 5.

[0017] To improve the quality of the rolled fabric, the present invention provides a width adjustment device 8 that is provided diagonally below the fabric rolling roller 5. The width adjustment device 8 includes a fixed base 81, which is an open box of triangular prism. The side of the open box facing the fabric rolling roller 5 is an inclined open surface. Two movable seats 82 are arranged in the open box at intervals. An adjustment drive mechanism 83 for driving the movable seats 82 to move linearly is provided on the back of the open box. The width adjustment device 8 also includes two limiting members 84 that correspond one-to-one with the movable seats 82. The limiting members 84 are provided with U-shaped arms 841 that are inserted into the roller surface of the fabric rolling roller 5. The ends of the U-shaped arms 841 are provided with insert rods 842. The side of the movable seat 82 facing the fabric rolling roller 5 is inclined. Two insert tubes 821 that cooperate with the insert rods 842 are provided on the movable seat 82.

[0018] Specifically, the triangular prism design of the fixed seat 81 provides sufficient space for the fabric rolling roller 5 to ensure the roll capacity. The movable seat 82, driven by the adjustment drive mechanism 83, can reciprocate linearly inside the fixed seat 81 to obtain different real-time positions. The limiting member 84 is manually forked onto the fabric rolling roller 5. The root of the U-shaped opening of the U-shaped arm 841 engages with the roller surface of the fabric rolling roller 5 but does not rotate with the rotation of the fabric rolling roller 5. The end of the limiting member 84 is positioned and engaged with the insertion tube 821 through the insertion rod 842, thereby cooperating with the movable seat 82 to obtain a reasonable width adjustment range on the working side of the fabric rolling roller 5. This width adjustment range is the maximum width of the fabric roll, providing a relatively limited roll width for the fabric. This avoids excessive cross-section of the fabric in the width direction, which would affect the tension at both ends of the fabric width. This allows the fabric to fall within a limited width range as much as possible, which helps to ensure the uniformity of tension at both ends of the fabric width, thereby ensuring the quality of the fabric.

[0019] To improve the quality of fabric rolls, the limiting member 84 provided by this utility model includes a semi-circular end plate 843. A guide cone 844 is provided on the side of the end plate 843 facing the middle position of the roll roller 5, and the guide cone 844 is connected to the U-shaped arm 841. The width range formed by the end plates 843 of the two limiting members 84 is slightly larger than the distance between the roots of the guide cones 844. Therefore, the end plates 843 can allow the initial section of the fabric to fall near the center of the roll roller 5 along its surface and the surface of the guide cones 844. As the thickness of the fabric increases, the end plates 843 leave an appropriate margin for the width of the fabric, avoiding excessive pressure of the fabric on the end of the limiting member 84 and increasing the load on the limiting member 84 and other components, which is beneficial to extending the actual service life of the limiting member 84 and the moving seat 82.

[0020] To facilitate the disassembly and assembly of the limiting component 84, this utility model provides a pair of handle holes 845 on the end plate 843 for workers to hold and operate, making it easy to pick up and put down the limiting component 84.

[0021] To improve the mobility of the movable seat 82 within the open box, this invention provides an upper guide plate 811 at the top of the open box and a lower guide plate 812 at the bottom of the open box. The upper and lower guide plates 811 and 812 slide in contact with the surface of the movable seat 82. The upper and lower guide plates 811 and 812 increase the direction of the open box's restriction on the movable seat 82, providing guidance while improving the movable seat 82's anti-overturning performance. They also reduce the shear load on the guide rod 831 and the lead screw 832, which is beneficial for improving the driving performance of the adjusting motor 833 on the lead screw 832 and ensuring a reasonable service life for the relevant components.

[0022] To improve transmission performance, the open box provided by this utility model is provided with a guide port 813, and the movable seat 82 is provided with a slider 834 that cooperates with the guide port. The slider 834 is provided with a guide hole and a transmission hole. The adjustment drive mechanism 83 includes a guide rod 831 that cooperates with the guide hole and a lead screw 832 that cooperates with the transmission hole. An adjustment motor 833 is provided at the end of the lead screw 832. The adjustment motor 833 provides power to the lead screw 832 and the transmission hole. The rotation of the lead screw 832 is converted into the horizontal movement of the slider 834. The transmission patterns in the transmission holes of the two sliders 834 are opposite, so one set of adjustment motor 833 and lead screw 832 can synchronously drive the two movable seats 82, ultimately making the two limiting members 84 have a better symmetrical relationship on the fabric winding roller 5, which is beneficial to improving the consistency of the working direction of the fabric and the main machine, and ensuring the fabric winding effect.

[0023] In order to control the accuracy of the real-time fabric winding width of the fabric winding roller 5, this utility model provides a length scale 85 on the fixed seat 81. By observing the relative relationship between the side of the movable seat 82 and the length scale 85, it can be determined whether the actual working width of the fabric winding roller 5 meets the requirements, so as to make timely adjustments.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
