Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a supply device for sewing multi-layer fabrics. Background Technology

[0002] The design and application of multi-layer fabric seams are primarily to meet the specific needs of downstream customers in the wind power generation sector. During the manufacturing process of wind turbine blades, multiple layers of fabric are laid inside the blades to enhance their structural strength and performance stability. To improve production efficiency and ensure product quality, the upstream processing companies adjust parameters such as the number of fabric layers, fabric length, and specifications of each layer according to the specific requirements of the downstream customers, and process them into small rolls of fabric that meet the requirements.

[0003] Small rolls of fabric require multiple layers to be sewn together, with varying numbers and positions of layers. The sewing of these multiple layers must be precise, avoiding misalignment and unevenness. Therefore, a feeding device for sewing multi-layered fabrics needs to be designed. This device must effectively eliminate unevenness and wrinkles that occur during fabric laying, while also addressing the efficiency issues of batch sewing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a supply device for sewing multi-layer fabrics.

[0005] To achieve the above objectives, the technical solution of this utility model is: a supply device for sewing multi-layer fabrics, including a first machine base and a second machine base. A plurality of fixed seats are installed on the first machine base along its length direction. A placement shaft for placing a roll of fabric is horizontally rotatably installed on the fixed seats. A limiting beam is connected to the side of the second machine base through an adjustable component. One end of the limiting beam has a guide edge with an arc surface.

[0006] The adjustable component includes an L-shaped connecting block and a fastener. The upper end of the L-shaped connecting block is fixedly connected to the other side of the limiting beam. The lower end of the L-shaped connecting block has a connecting hole. The second machine base has recessed notches on both sides that cooperate with the L-shaped connecting block. The recessed notches also have strip holes. The fastener passes through the connecting hole and the strip hole and fixes the L-shaped connecting block to the second machine base.

[0007] The placement shaft end is threaded with a nut, and the placement shaft end is also fitted with a friction plate, which is arranged between the nut and the fixed seat.

[0008] The first machine base is also equipped with an adjustable support block one, and the second machine base is also equipped with an adjustable support block two.

[0009] The limiting beam also has multiple weight-reducing holes.

[0010] By adopting the above technical solution, the beneficial effects of this utility model are: This invention utilizes multiple placement shafts. During the sewing process, workers pull out the corresponding fabric from the placement shafts according to the required stacking order. When the fabric is pulled out and laid on the second sewing machine, it is guided by the guide edge of the limiting beam, ensuring a relatively neat laying. If necessary, workers can tidy up the multi-layered fabric laid on the second sewing machine before proceeding with subsequent sewing processes. Since the fabric rolls can be stored on the placement shafts, workers can quickly pull out the required fabric as needed. At the same time, the limiting beam can effectively guide the fabric during laying, reducing the frequency of worker tidying and ultimately greatly improving the overall sewing efficiency.

[0012] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0013] like Figure 1-3 As shown, this multi-layer fabric sewing supply device includes a first machine base 1 and a second machine base 7. Several fixed seats 10 are installed on the first machine base 1 along its length. In this embodiment, the number of fixed seats 10 is four, and this specific number can be increased or decreased as needed. A placement shaft 3 for placing fabric rolls is horizontally rotatably installed on the fixed seat 10. A limiting beam 4 is connected to the side of the second machine base 7 through an adjustable component. Specifically, the limiting beam 4 also has multiple weight-reducing holes 4b. One end of the limiting beam 4 has a guide edge 4a with an arc surface. In practice, the limiting beam 4 can be installed on one side of the two sides of the second machine base 7 as needed.

[0014] The adjustable component includes an L-shaped connecting block 5 and a fastener 8. The upper end of the L-shaped connecting block 5 is fixedly connected to the other side of the limiting beam 4. The lower end of the L-shaped connecting block 5 has a connecting hole 5a. The second machine base 7 has recessed notches 7a on both sides that cooperate with the L-shaped connecting block 5. The recessed notches 7a also have strip holes 7b. The fastener 8 passes through the connecting hole 5a and the strip hole 7b and fixes the L-shaped connecting block 5 to the second machine base 7. With this structure, the position of the limiting beam 4 can be adjusted by adjusting the position of the L-shaped connecting block 5 at the recessed notch 7a.

[0015] The end of the placement shaft 3 is threaded with a nut 9, and the end of the placement shaft 3 is also fitted with a friction plate 11, which is arranged between the nut 9 and the fixed seat 10. With this structure, by adjusting the position of the nut 9, the rotational resistance of the placement shaft 3 can be controlled by the friction plate 11, so that the fabric roll can only drive the placement shaft 3 to rotate together when the worker pulls the fabric.

[0016] The first machine platform 1 is also equipped with an adjustable support block 1 2, and the second machine platform 7 is also equipped with an adjustable support block 2 6, which can adjust the height of the first machine platform 1 and the second machine platform 7.

[0017] In practice, one end of the second machine 7 is close to the first machine 1, and the other end of the second machine 7 is close to the existing sewing machine. The first worker is responsible for sewing, the second worker is responsible for pulling the folded fabric to the sewing machine, and the third worker is responsible for pulling out the fabric placed at the shaft 3. The three work together to complete the sewing of the fabric.

[0018] In this invention, multiple placement shafts 3 are designed so that during the sewing process, workers can pull out the corresponding fabric from the placement shafts 3 according to the required stacking order. When the fabric is pulled out and laid on the second machine table 7, the guide edge 4a of the limiting beam 4 is used to guide it so that it can be laid out relatively neatly. If necessary, workers can tidy up the multi-layered fabric laid on the second machine table 7 before proceeding with the subsequent sewing process. Since the fabric roll can be stored on the placement shafts 3, workers can quickly pull out the required fabric as needed. At the same time, the limiting beam 4 can effectively guide it during laying, reducing the frequency of workers tidying up and ultimately greatly improving the efficiency of the entire sewing process.

[0019] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0020] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
