Description

Technical Field

[0001] This utility model relates to the field of textile and garment production technology, and in particular to an automatic fabric spreading device. Background Technology

[0002] Automatic fabric laying devices are mainly used in various industries such as textiles, apparel, home textiles, and automotive interiors. These devices convert woven fabric from a roll to a flat lay for subsequent processes such as inspection, finishing, and packaging. They can quickly and neatly lay out fabrics, reducing the labor intensity of manual operations and improving the automation level and production efficiency of textile production.

[0003] Automatic fabric laying devices can unfold fabric at high speed and continuously. Compared with manual laying, it can greatly shorten the laying time and meet the needs of large-scale production. Taking curtain production as an example, fabrics of different colors and materials (such as blackout fabric, gauze curtains, etc.) need to be laid and cut according to the window size, and the width of the fabric is adjusted by cutting.

[0004] Existing automatic fabric laying devices sometimes struggle to achieve precision when cutting fabric width. This not only affects fabric utilization but also causes problems for subsequent processing steps, increases costs, and reduces overall product quality and production efficiency. Therefore, an automatic fabric laying device is proposed to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 2 to 3In one embodiment of this utility model: a concave plate 11 is fixedly connected to the outer side of the fabric laying board 22, and a hydraulic cylinder 10 is fixedly connected to the top of the concave plate 11. A moving plate 12 is fixedly connected to the drive end of the hydraulic cylinder 10 for vertical movement. Two racks 13 are slidably connected inside the moving plate 12. A second motor 20 is fixedly connected to the inner wall of the moving plate 12 to create suitable positional conditions for subsequent cutting of fabrics of different thicknesses. A gear 14 is fixedly connected to the drive end of the second motor 20, which drives the gear 14 to rotate. The gear 14 and the two racks 13 are meshed, and the rotation of the gear 14 will be precise. The movement is converted into linear motion of two racks 13. A blade 15 is fixedly connected to the bottom of each rack 13. The blade 15 precisely cuts the fabric as the racks 13 move, ensuring the needs of fabrics of different widths are met. Sliding plates 6 are fixedly connected to both sides of the fabric laying plate 22. An adjustment assembly is installed inside each sliding plate 6, including two adjusting rods 23. A pressure rod 16 is rotatably connected to the adjacent side of the two adjusting rods 23. A torsion spring 17 is fitted on one side of each adjusting rod 23, allowing the pressure rod 16 to flexibly adjust the pressure according to actual needs, better securing the fabric and preventing displacement during cutting. The adjusting rods 23 are rotatably connected to the grooves of the sliding plates 6. A motor 7 is fixedly connected to the outside of the sliding plates 6. Two rotating wheels 8 are rotatably connected to one side of one of the sliding plates 6. The drive end of the motor 7 is fixedly connected to one side of one of the rotating wheels 8. A belt 9 is externally coupled to the two rotating wheels 8. A moving rod 18 is fixedly connected to the outside of the belt 9, achieving the required tension for different fabrics.

[0033] Reference Figure 1 , Figure 3 and Figure 4 The top of the two sliding plates 6 is fixedly connected to the placement plate 5, and the top of the placement plate 5 is fixedly connected to the fabric placement plate 1. The fabric placement plate 1 is an important area for the initial placement of the fabric. The inside of the fabric placement plate 1 is fixedly connected to two limiting springs 3. The adjacent sides of the two limiting springs 3 are fixedly connected to limiting plates 2. The limiting plates 2 are externally slidably connected to the top of the fabric placement plate 1. The limiting plates 2 limit the fabric of different widths to ensure that the fabric is placed neatly and orderly. The top of the placement plate 5 is rotatably connected to a rotating rod 4. A tension rod 19 is installed on one side of the placement plate 5 to adjust the tension of the fabric during the conveying process. A fabric rolling rod 21 is installed on one side of the fabric laying plate 22 to orderly roll up the fabric after cutting.

[0034] Working principle: The worker places the fabric on the fabric placement plate 1, slides a limiting plate 2, and places the fabric between the two limiting plates 2. Both limiting plates 2 compress the limiting springs 3. After being compressed, the limiting springs 3 store elastic potential energy and release it to the limiting plates 2, thereby fixing the fabric. The fabric placement plate 1 has a groove. The worker pulls one end of the fabric out of the groove, passes it around the rotating rod 4, and passes it through the four rods in the middle of the tension rod 19. This process stretches the tension of the fabric. Then the fabric is passed over the moving rod 18. When it is necessary to adjust the tension of the fabric, the motor 7 is started. The motor 7 drives the rotating wheel 8 to rotate, and the rotating wheel 8 drives the belt 9 to rotate. The outer wall of the belt 9 is fixedly connected to the moving rod 18. The belt 9 drives the moving rod 18 to move up and down to meet the tension requirements of different fabrics.

[0035] Next, place the fabric under the pressure rod 16. The sliding plate 6 is rotatably connected to the adjusting rod 23. A torsion spring 17 is fixedly connected between the sliding plate 6 and the adjusting rod 23. Lifting the adjusting rod 23 stretches the torsion spring 17, causing the torsion spring 17 to apply force to the adjusting rod 23, making the pressure rod 16 press the fabric more evenly. Pull the fabric under the concave plate 11 and start the hydraulic cylinder 10. The hydraulic cylinder 10 drives the moving plate 12 to move up and down. The bottom of the moving plate 12 is fixed with a blade 15 for cutting the fabric. Then, start the motor 20. The rotation of the motor 20 drives the gear 14 to rotate. The moving plate 12 is slidably connected to two racks 13. The gear 14 and the two racks 13 are meshed, so that the rotation of the gear 14 can control the sliding of the racks 13, thereby adjusting the distance of the blades 15. This allows the two blades 15 to move simultaneously, cutting fabric of different widths. The cut fabric is collected by starting the rotating fabric winding rod 21.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
