[0002] Curtains are made of materials such as cloth, linen, gauze, aluminum sheets, wood sheets, and metal, and serve the functions of shading, heat insulation, and regulating indoor light. Fabric curtains are categorized by material, including cotton gauze, polyester fabric, cotton-polyester blends, cotton-linen blends, and non-woven fabrics. Different materials, textures, colors, and patterns combine to create curtains of various styles, complementing different interior design styles.
[0003] During the manufacturing process of curtains, in order to ensure the neatness and beauty of the edges, the outer edge is folded once and then sewn together. Currently, this task is generally done manually using a sewing machine. However, some novices often cannot control the feeding speed of the two folded parts when using a sewing machine, which can easily lead to wrinkles on the outer edge after sewing.
[0004] Therefore, it is necessary to provide a sewing device for curtain fabric to solve the above-mentioned technical problems. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0020] Please refer to the following: Figure 1-3 The sewing device for the curtain fabric includes a table 1, a sewing machine body 2 is provided in the middle of the upper surface of the table 1, and auxiliary fabric feeding structures are provided on the upper surface of the table 1 and at the front and rear of the sewing machine body 2.
[0021] The two auxiliary fabric feeding structures are identical. One of the auxiliary fabric feeding structures includes a through groove 3 that is vertically opened on the upper surface of the table 1 and located at the front of the sewing machine body 2 and is set along the length of the table 1. A lower guide roller 4 is laterally rotatably connected inside the through groove 3 along its length. Multiple columns 5 are vertically fixedly connected to the upper surface of the table 1 and at one end of the through groove 3. A slider 6 is vertically slidably connected to the outer surface of the multiple columns 5. An upper guide roller 7 corresponding to the lower guide roller 4 is laterally rotatably connected to one side surface of the multiple sliders 6. Multiple tension springs 8 are vertically fixedly connected between the sliders 6 and the table 1.
[0022] When the multiple tension springs 8 are not under force, the upper guide roller 7 and the lower guide roller 4 are in contact with each other.
[0023] A fixed seat 10 is fixedly connected to the lower surface of the table 1 and one end of the through groove 3. A multi-track synchronous wheel 11 is laterally rotatably connected to one side surface of the fixed seat 10. A synchronous wheel 9 is fixedly connected to the outer surface of the roller shaft of the lower guide roller 4. The inner rail of the multi-track synchronous wheel 11 and the synchronous wheel 9 are connected by a synchronous belt drive.
[0024] The outer rails of the multi-track synchronous pulleys 11 in the two auxiliary feeding structures are connected by synchronous belt drive.
[0025] In this embodiment, the multiple tension springs 8 in the device always apply a downward pulling force to the slider 6, so the slider 6 always tends to move downward. This causes the upper guide roller 7, which is rotatably connected to it, to also always tend to move downward. Its lower surface will always be in contact with the upper surface of the lower guide roller 4. After the folded outer edge of the curtain is fed between the two, it will be clamped by the two and will move laterally as the lower guide roller 4 rotates. By using the guide rollers of the two auxiliary feeding structures to clamp and transport the outer edge of the curtain, it is possible to ensure that the curtain can move at a uniform speed and also ensure the alignment of the folded layers. This prevents uneven sewing and wrinkles when beginners use the device to sew the outer edge of the curtain. It can also improve sewing efficiency to a certain extent and reduce the workload of workers.
[0026] The two auxiliary feeding structures in the device are connected by a synchronous belt drive at the bottom of the multi-track synchronous wheel 11. At the same time, the two multi-track synchronous wheels 11 are also connected to the synchronous wheel 9 in their respective structures by a synchronous belt drive. This allows the multiple multi-track synchronous wheels 11 and multiple synchronous wheels 9 to rotate at the same speed and in the same direction. This also allows the lower guide rollers 4 in the two structures to rotate synchronously and in the same direction, so as to drive the curtain to move at a uniform speed and prevent the feeding speed at both ends from being inconsistent.
[0027] A motor 12 is horizontally fixedly connected to the lower surface of the tabletop 1 and to the outside of a fixed base 10. The output shaft of the motor 12 rotatably passes through the fixed base 10 and is fixedly connected to one end of the multi-rail synchronous wheel 11.
[0028] In this embodiment, when the motor 12 is running, it can drive a multi-rail synchronous wheel 11 fixedly connected to its output shaft to rotate, thereby driving the two auxiliary feeding structures to run synchronously.
[0029] Multiple support legs 13 are vertically fixedly connected to the lower surface of the tabletop 1 at multiple corners, and a reinforcing rod 14 is fixedly connected between each pair of adjacent support legs 13 on both sides and the rear.
[0030] In this embodiment, multiple support legs 13 all provide support, and multiple reinforcing rods 14 can improve the structural strength of multiple support legs 13.
[0031] The working principle of the curtain fabric sewing device provided by this utility model is as follows: The multiple tension springs 8 in the device always apply a downward pulling force to the slider 6, so the slider 6 always has a downward movement tendency, which makes the upper guide roller 7, which is rotatably connected to it, also always have a downward movement tendency. Its lower surface will always be in contact with the upper surface of the lower guide roller 4. After the folded outer edge of the curtain is fed between the two, it will be clamped by the two and will move laterally with the rotation of the lower guide roller 4. By using the guide rollers of the two auxiliary fabric feeding structures to clamp and transport the outer edge of the curtain, it can ensure that the curtain can move at a uniform speed and also ensure the alignment of the folded layers. This prevents uneven sewing and wrinkles when beginners use this device to sew the outer edge of the curtain, and can also improve sewing efficiency and reduce the workload of workers to a certain extent.
[0032] Compared with related technologies, the curtain fabric sewing device provided by this utility model has the following beneficial effects: By setting two auxiliary feeding structures, when the outer edge of the curtain is folded up, the curtain can be fed at a uniform speed through the two auxiliary feeding structures. Even novice operators can ensure the neatness and beauty of the curtain outer edge after sewing. It also improves sewing efficiency to a certain extent and reduces the workload during sewing, thereby improving the practicality of the device.
[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
