Description

Technical Field

[0001] This utility model belongs to the field of textile machinery technology and relates to a 90° reversing conveying device for base fabric, which realizes 90° reversing conveying of base fabric and has the functions of flattening base fabric and maintaining a certain tension. Background Technology

[0002] In the production and processing of base fabric, it is often necessary to change the orientation of the base fabric, such as changing the base fabric from being conveyed laterally to being conveyed longitudinally. In the existing technology, ordinary reversing devices have complex structures and often lack effective flattening and tension control functions, which can easily lead to problems such as wrinkles, deviation, or uneven tension in the base fabric during the reversal process, affecting the quality of subsequent processing and production efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a 90° reversing conveying device for base fabric, which can simultaneously achieve reliable reversing, effective flattening and stable tension control, thus solving the technical problems in the background art.

[0004] The objective of this utility model is achieved through the following technical solution: A base fabric 90° reversing conveying device includes a frame, a reversing mechanism, a flattening mechanism, and a tension control mechanism. The reversing mechanism includes a guide roller and a 90° reversing rod mounted on the frame for guiding the base fabric and enabling it to complete a 90° direction change. The flattening mechanism includes a photoelectric edge suction device adjustment bracket mounted on the frame and an infrared photoelectric edge suction device mounted on the photoelectric edge suction device adjustment bracket for flattening the base fabric during operation. The tension control mechanism includes a tension frame and an adjusting connecting bolt mounted on the frame, and a tension spring connected between the two for providing and maintaining stable tension for the base fabric.

[0005] As a further improvement of this utility model, the infrared photoelectric edge suction device is configured as two devices, one above the other, and the positions of the two infrared photoelectric edge suction devices can be adjusted on the photoelectric edge suction device adjustment bracket to adapt to base fabrics of different widths.

[0006] As a further improvement of this utility model, the photoelectric edge suction device adjustment bracket is a vertical bracket, and an adjustment seat is provided on it. The adjustment seat can be locked and fixed on the vertical bracket by bolts, and the infrared photoelectric edge suction device is set on the corresponding adjustment seat.

[0007] As a further improvement of this utility model, the 90° reversing rod is distributed at a 45° angle with the horizontal plane; the number of the guide rollers is three, one of which is horizontally set and its two ends are mounted on the upper end of the frame through bearing seats, and the other two guide rollers are vertically set and their two ends are mounted on the frame through bearing seats, with the two guide rollers located on the left and right sides of the 90° reversing rod respectively.

[0008] As a further improvement of this utility model, a bolt mounting plate is provided on the frame, and bolt holes are provided on the bolt mounting plate. The adjusting union bolt is threaded into the bolt holes. One end of the tension frame on the same side as the bolt mounting plate is pivotally mounted on the frame, and a guide roller for guiding the base fabric is pivotally mounted on the other side of the tension frame.

[0009] As a further improvement of this utility model, a telescopic member is provided between the tension frame and the machine frame on the same side as the guide roller to limit the range of swing of the tension frame.

[0010] The above technical solution has the following advantages: the spacing of the photoelectric edge suction device is adjustable and the spring tension is adjustable, which can adapt to the production of base fabrics of different specifications; it integrates three major functions: 90° reversal, base fabric flattening and tension control, which effectively prevents wrinkles, deviation and tension fluctuations when the base fabric is reversed, thereby improving product quality and production efficiency.

[0018] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0019] First embodiment, such as Figures 1-4 As shown, a base fabric 90° reversing conveying device includes a frame 1, a reversing mechanism, a flattening mechanism, and a tension control mechanism. The frame 1 serves as the main support for the entire device, providing a solid foundation for the other components. The reversing mechanism includes a guide roller and a 90° reversing rod 4 mounted on the frame 1. Through the cooperation between the guide roller and the 90° reversing rod 4, the base fabric 3 is guided and 90° reversed. The guide roller and the 90° reversing rod 4 can be made of wear-resistant, smooth metal or polymer materials to reduce frictional damage to the base fabric 3.

[0020] The flattening mechanism includes a photoelectric edge suction device adjustment bracket 6 mounted on the frame 1 and an infrared photoelectric edge suction device 5 mounted on the photoelectric edge suction device adjustment bracket 6. There are two infrared photoelectric edge suction devices 5, and their positions on the photoelectric edge suction device adjustment bracket 6 can be adjusted to adapt to the flattening requirements of base fabrics 3 of different widths. The infrared photoelectric edge suction device 5 can accurately detect the edge position of the base fabric 3 and automatically adjust it to ensure that the base fabric 3 runs flat.

[0021] The tension control mechanism includes a tension frame 7 and an adjusting joint bolt 9 mounted on the frame 1, and a tension spring 8 connected between the two. By adjusting the joint bolt 9, the tension length of the tension spring 8 can be changed, thereby flexibly adjusting the tension of the base fabric 3 and providing and maintaining a stable tension for the base fabric 3.

[0022] In this design, the photoelectric edge-collecting device adjustment bracket 6 adopts a vertical bracket form, which is simple and stable. An adjustment seat 10 is mounted on the vertical bracket, which can slide flexibly up and down along the vertical bracket to adapt to different positional requirements. When the adjustment seat 10 slides to the appropriate position, it can be securely locked onto the vertical bracket with bolts. The infrared photoelectric edge-collecting device 5 is precisely installed on the corresponding adjustment seat 10, thus allowing for precise adjustment of the height of the infrared photoelectric edge-collecting device 5 and ensuring a flattening effect.

[0023] In this 90° reversing conveyor for the base fabric, the 90° reversing rod 4 is positioned at a 45° angle to the horizontal plane. This angle ensures that the base fabric 3 experiences uniform force during reversal, resulting in smoother operation and reduced wrinkling. Three guide rollers are used. Guide roller 21 is placed horizontally, its ends securely mounted on the upper part of the frame 1 using bearing seats, providing support for the horizontal conveying of the base fabric 3. The other two guide rollers, 22 and 23, are vertically positioned, also mounted on the frame 1 using bearing seats, and located on the left and right sides of the 90° reversing rod 4, respectively. In actual use, the base fabric 3 first passes horizontally through guide roller 21, then changes direction along the 90° reversing rod 4 at a 45° angle to the horizontal plane, and then passes sequentially through guide rollers 22 and 23, finally completing the 90° reversal smoothly. This structural layout is reasonable and effectively ensures the smoothness and stability of the base fabric 3's reversal process.

[0024] In this 90° reversing conveying device for the base fabric, a bolt mounting plate 12 is specially provided on the frame 1. This bolt mounting plate 12 has several bolt holes, and adjusting bolts 9 can be threaded into these bolt holes. The position of the adjusting bolts 9 can be flexibly adjusted by rotating them. A tension frame 7, located on the same side as the bolt mounting plate 12, is pivotally mounted on the frame 1 at one end, while a guide roller 11 is pivotally mounted on the other side of the tension frame 7 to guide the base fabric 3 to run smoothly.

[0025] Meanwhile, a telescopic component 13 is provided between the tension frame 7 and the machine frame 1 on the same side as the guide roller 11. This telescopic component 13 is a ready-made part that can be purchased directly. It consists of a sleeve and a tube. The sleeve can move within the stroke limited by the tube. One end of the sleeve is installed on the machine frame 1, and the other end of the tube is installed on the tension frame 7. This structure effectively limits the swing range of the tension frame 7 and ensures stable and reliable tension control.

[0026] During installation, first, fix the guide roller, 90° reversing rod 4, photoelectric edge suction device adjustment bracket 6, tension frame 7, and adjusting union bolt 9 onto the frame 1 according to the design requirements. Then, install the infrared photoelectric edge suction device 5 onto the photoelectric edge suction device adjustment bracket 6, and initially adjust the spacing between the upper and lower infrared photoelectric edge suction devices 5. Finally, connect both ends of the tension spring 8 to the tension frame 7 and the adjusting union bolt 9, respectively.

[0027] During operation, the base fabric 3 sequentially passes over the guide roller 21, the 90° reversing rod 4, the guide roller 22, and the guide roller 23, completing a 90° directional change in the process. Infrared photoelectric edge suction devices 5, positioned at the top and bottom, monitor the edge position of the base fabric in real time and suction the edge of the base fabric 3 to achieve a flattening effect. The tension frame 7, under the action of the tension spring 8, applies an appropriate tension force to the base fabric 3. The magnitude of this tension force can be precisely adjusted by rotating the adjusting bolt 9 to change the stretch of the tension spring 8, thereby ensuring smooth conveying of the base fabric under stable tension.
