Description

Technical Field

[0002] In the field of automotive interior manufacturing, the production process of seat covers has a crucial impact on the quality of the final product. As a component that directly contacts the driver and passengers, the seat cover must not only meet the requirements of beauty and comfort, but also have good durability and wrinkle resistance. With the continuous development of the automotive industry, consumers' expectations for the quality of seat covers are increasing, which has prompted manufacturers to seek more advanced and efficient processes and equipment in the production process. However, during the sewing process of seat covers, the wrinkle problem of the fabric has always been a problem that has plagued the industry. Traditional sewing methods often make it difficult to effectively control the flatness of the fabric during the sewing process, resulting in wrinkles on the final sewn seat cover, which not only affects the appearance, but may also reduce the comfort and service life of the seat.

[0033] First, place the fabric of the seat cover on the workbench 1, clamp one side edge of the fabric between the support plate 2 10 close to the support plate 1 8 and the mounting plate 11, and ensure that the fabric is initially flat, start the driving component, adjust the position of the stretching plate 9, and move the stretching plate 9 in the sliding groove 1 so that the edges of both sides of the fabric are located between the corresponding support plate 2 10 and the mounting plate 11, then start the clamping component to drive the mounting plate 11, the buffer component and the pressing plate 12 to move downward, the pressing plate 12 clamps the edge of the fabric, and the buffer component performs buffering to prevent displacement and wrinkles and avoid damage to the fabric. , start the driving component again, drive the stretching plate 9 to move horizontally away from the supporting plate 8, the fabric is stretched, and the smoothing component moves with the stretching of the fabric to smooth it. After smoothing the wrinkles on the fabric, the fabric is flat and has no deformation. Then, the mounting plate 11 is driven to move upward through the clamping component, the clamping plate 12 releases the clamping on the edge of the fabric, and then the fabric is pulled, and the fabric is pulled directly under the sewing machine 7, and then the sewing machine 7 is started for sewing operation, so that the fabric can be stretched and wrinkles can be smoothed at the same time, thereby improving the sewing quality and preventing wrinkles from appearing again during sewing.

[0034] For further reference, Figure 1-Figure 3 The driving assembly includes: a rotating motor 201 and a threaded rod 202. The rotating motor 201 is fixedly installed on the top of one end of the support plate 8 away from the stretching plate 9. A sliding opening is provided on the top of one end of the stretching plate 9. The threaded rod 202 is horizontally arranged. One end of the threaded rod 202 is fixedly connected to the output shaft of the rotating motor 201. The stretching plate 9 is sleeved on the other end of the circumference of the threaded rod 202 through the sliding opening. The inner wall of the sliding opening is provided with a thread matching the threaded rod 202.

[0035] First, place the fabric of the seat cover on the workbench 1, clamp one side edge of the fabric between the support plate 2 10 close to the support plate 1 8 and the mounting plate 11, then start the rotating motor 201, the output shaft of the rotating motor 201 starts to rotate, driving the threaded rod 202 to rotate synchronously, and the stretching plate 9 will move horizontally along the circumferential direction of the threaded rod 202 to adapt to the stretching requirements of seat cover fabrics of different sizes, so that the edges on both sides of the fabric are located between the support plate 2 10 and the mounting plate 11, after fixing the fabric by the clamping assembly, start the rotating motor 201 again, drive the stretching plate 9 to move horizontally away from the support plate 8, stretch the fabric, and stretch the fabric flat.

[0036] For further reference, Figure 1-Figure 4, a sliding groove 2 is provided on the other side and the middle position of the top of the workbench 1, and the two sliding grooves 2 are arranged in parallel, and one of the sliding grooves 2 is located between the two sliding grooves 1. The clamping assembly includes: a rotating motor 2 301 and a threaded rod 2 302. The two rotating motors 301 are fixedly installed at the bottom center position of the corresponding support plate 2 10, and the two rotating motors 301 are respectively located in the corresponding sliding grooves 2. A sliding opening 2 is provided at the top center position of the mounting plate 11, and the threaded rod 2 302 is vertically arranged. The bottom of the threaded rod 2 302 is fixedly connected to the output shaft of the rotating motor 301. The mounting plate 11 is sleeved on the top of the threaded rod 2 302 through the sliding opening 2, and the inner wall of the sliding opening 2 is provided with a thread matching the threaded rod 2 302.

[0037] When both side edges of the fabric are located between the supporting plate 10 and the mounting plate 11, when the clamping assembly is used, the rotating motor 301 is started, and the output shaft of the rotating motor 301 drives the threaded rod 302 to start rotating, driving the mounting plate 11, the buffer assembly and the clamping plate 12 to move downward until the edges of both sides of the fabric are clamped and fixed by the clamping plate 12, to prevent the two sides of the fabric from loosening during the stretching of the fabric, which would affect the stretching of the fabric and the smoothing of wrinkles.

[0038] For further reference, Figure 1-Figure 4 , the limiting component 1 includes: a limiting rod 1 401, two limiting plates 402, a sliding opening 3 is opened at the top of the other end of one side of the stretching plate 9, the limiting rod 1 401 is horizontally arranged, one end of the limiting rod 1 401 is fixedly connected to the other side of the support plate 1 8, and the other end of the limiting rod 1 401 is slidably connected to the sliding opening 3, and the two limiting plates 402 are respectively fixedly installed on the threaded rod 1 202 and the other end of the limiting rod 1 401, and the limiting rod 1 401 is arranged parallel to the threaded rod 1 202; the limiting component 2 includes: a limiting rod 2 403, a sliding opening 4 is opened at the center position of the top of the mounting plate 11, the limiting rod 2 403 is vertically arranged, the bottom of the limiting rod 2 403 is fixedly connected to the support plate 2 10, the inner wall of the sliding opening 4 is slidably connected to the top of the limiting rod 2 403, and the limiting rod 2 403 is arranged parallel to the threaded rod 2 302.

[0039] When the rotating motor 201 drives the threaded rod 202 to rotate and move the stretching plate 9, the limit rod 401 effectively prevents the stretching plate 9 from deflecting or rotating during the movement, ensuring that it only moves stably along the predetermined straight line direction, thereby ensuring the accuracy and reliability of the stretching action; when the rotating motor 2 301 drives the threaded rod 2 302 to rotate and move the mounting plate 11, the limit rod 2 403 limits the mounting plate 11 to move up and down only in the vertical direction, so that the mounting plate 11 can move accurately during the process of clamping the fabric, thereby achieving the fixing operation of the fabric.

[0040] For further reference, Figure 1-Figure 4The sliding assembly includes: a slide rail 501 and a slide block 502. The slide rail 501 is fixedly installed on the bottom inner wall of a sliding groove. The slide block 502 is slidably installed on the slide rail 501. The tops of the two slide blocks 502 are fixedly connected to the two ends of the bottom of the stretching plate 9 respectively.

[0041] When the driving assembly drives the stretching plate 9 to move, the slide block 502 enables the stretching plate 9 to move smoothly in the horizontal direction on the slide rail 501, so as to adjust the position of the stretching plate 9 and facilitate the subsequent stretching of the seat cover fabric.

[0042] For further reference, Figure 1 , Figure 3 and Figure 6 The smoothing component includes: a mounting groove plate 601 and a rotating roller 602. The two mounting groove plates 601 are fixedly installed on the sides of the two mounting plates 11 close to each other, and the rotating roller 602 is rotatably installed between the inner walls at both ends of the mounting groove plates 601.

[0043] When the stretching plate 9 is adjusted to a suitable position and the fabric is fixed by a clamping assembly, etc., the rotating roller 602 is close to the surface of the fabric, and the driving assembly is started to drive the stretching plate 9 to move horizontally away from the supporting plate 8, and at the same time drive the smoothing assembly to move together. During the stretching operation of the seat cover fabric, the fabric contacts the rotating roller 602. As the stretching action proceeds, the rotating roller 602 will rotate accordingly, and use its own gravity and rolling to smooth the fabric, preventing wrinkles from appearing on the fabric during stretching, allowing the fabric to participate in the sewing operation in a relatively flat state, thereby achieving the goal of stretching the fabric and smoothing wrinkles at the same time, improving the sewing quality, and preventing wrinkles from appearing again during sewing.

[0044] For further reference, Figure 4-Figure 6 The buffer assembly includes: a sleeve 13, an insertion rod 14 and a buffer spring 15. The sleeve 13 is fixedly installed at the bottom of the mounting plate 11, the insertion rod 14 is vertically arranged, the insertion rod 14 is inserted into the corresponding sleeve 13, the buffer spring 15 is fixedly installed between the top of the insertion rod 14 and the mounting plate 11, and the bottom of the insertion rod 14 is fixedly connected to the clamping plate 12.

[0045] When the clamping assembly is started, the mounting plate 11, the buffer assembly and the pressing plate 12 are driven to move downward. When several pressing plates 12 press the edge of the seat cover fabric, the insertion rod 14 will be inserted up and down in the sleeve 13, and the buffer spring 15 will be compressed accordingly. The elastic deformation of the buffer spring 15 itself is used to absorb and buffer the impact force generated by the pressing action, avoiding damage to the seat cover fabric due to excessive pressing force. At the same time, it can also allow the pressing plate 12 to press the edge of the fabric more stably and appropriately, ensuring that the fabric is fixed in position during the sewing process, which is conducive to the smooth progress of the stretching work.

[0046] For further reference, Figure 3 , Figure 4 and Figure 6 A plurality of rotating rollers 16 are equidistantly mounted on one side of the top of the two support plates 10 for material discharging and rotation, and a plurality of sliding openings 5 ​​are equidistantly opened on the bottom of the two mounting plates 11 for material discharging, and the sliding openings 5 ​​are arranged one-to-one correspondingly with the rotating rollers 16.

[0047] When both side edges of the fabric are located between the supporting plate 10 and the mounting plate 11, a plurality of rotating rollers 16 will contact the edges of the fabric. In the process of moving the mounting plate 11 downward to clamp the fabric through the clamping assembly, the rotating rollers 16 can pass through the corresponding sliding openings 5, thereby reducing damage to the edges of the fabric during the clamping operation. After the clamping plate 12 releases the clamping of the edges of the fabric, the fabric is pulled and directly pulled under the sewing machine 7. The rotating rollers 16 are driven by the edges of the fabric to rotate, thereby reducing the friction generated at the edges of the fabric when pulling the fabric, making the pulling action of the fabric smoother, preventing wrinkles when pulling the fabric, and facilitating pulling the fabric to the bottom of the sewing machine 7.

[0048] refer to Figure 1-Figure 6 A sewing method of a seat cover anti-wrinkle sewing device comprises the following steps:

[0049] Step 1: First, place the fabric of the seat cover flatly on the workbench 1, and clamp one side edge of the fabric between the support plate 2 10 close to the support plate 1 8 and the mounting plate 11;

[0050] Step 2: Then start the rotating motor 201, and its output shaft drives the threaded rod 202 to rotate, and the stretching plate 9 moves smoothly on the slide rail 501 through the sliding block 502, and moves horizontally along the threaded rod 202, so that the edges of both sides of the fabric are located between the supporting plate 2 10 and the mounting plate 11;

[0051] Step 3: Then start the second rotating motor 301, the output shaft drives the second threaded rod 302 to rotate, the mounting plate 11 drives the buffer assembly and the clamping plate 12 to move downward under the vertical precision movement ensured by the second limit rod 403, the insertion rod 14 moves in the sleeve 13 to compress the buffer spring 15, and finally clamps the edge of the fabric through the clamping plate 12;

[0052] Step 4: Then, the rotating motor 201 is started again to drive the stretching plate 9 to stretch the fabric away from the supporting plate 8. During the stretching, the rotating roller 602 moves with the fabric by its own rolling and weight to smooth the fabric. The fabric is stretched and flattened, and the smoothing component prevents wrinkles from appearing during the stretching of the fabric.

[0053] Step 5: After the stretching is completed, the mounting plate 11 is finally driven upward by the clamping assembly to release the clamping plate 12, and then the fabric is pulled so that its edge drives the rotating roller 2 16 to rotate, and the fabric is pulled under the sewing machine 7, and the sewing machine 7 is started to perform sewing operation; the rotating roller 2 16 is driven by the edge of the fabric to rotate, thereby reducing the friction generated by the edge of the fabric when pulling the fabric, making the pulling action of the fabric smoother and preventing wrinkles from occurring when the fabric is pulled.
