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.

[0029] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, in order to achieve the above objectives, this utility model provides a fabric 6 folding mechanism, including: a base plate 1 and a support plate 2 disposed on a first side of the base plate 11, the surface of the support plate 2 being used to lay the fabric 6, wherein the support plate 2 is disposed on the front side of the base plate 1.

[0031] The folding assembly 3 includes a folding plate 301 disposed above the tray 2. The folding plate 301 extends along a first direction. By controlling and driving the folding plate 301 to reciprocate along a second direction, the fabric 6 can be folded. By controlling the position of the folding plate 301 in the second direction, the folded edge 601 of the fabric 6 is aligned with the edge of the first side of the folding plate 301, thus determining the position of the folded edge 601 on the fabric 6. By controlling the position of the folding plate 301 in the second direction, the position of the folded edge 601 on the fabric 6 is precisely controlled, thereby flexibly adjusting the folding size of the fabric 6. Simultaneously, it can fold fabrics 6 of different sizes and specifications, effectively improving the compatibility of the fabric 6 folding assembly 3. The first direction is referenced... Figure 2 In the X direction, the second direction is for reference. Figure 2 as well as Figures 4 to 8In the Y direction, the second direction is perpendicular to the first direction, and both the second and first directions lie within the first plane.

[0032] The pressing assembly 5 includes a pressing plate 501 disposed above the support plate 2. The pressing plate 501 extends along a first direction. By controlling and driving the pressing plate 501 to reciprocate along a third direction, the pressing plate 501 can press the fabric 6 to ensure smooth folding of the fabric 6. By controlling the position of the pressing plate 501 in a second direction, the edge of the first side of the pressing plate 501 is aligned with the folded edge 601 of the fabric 6 and the fabric 6 is pressed. Then, the folding plate 301 is controlled and driven to move along the second direction, precisely controlling the folding of the fabric 6 at the folded edge 601 position, effectively improving the positional accuracy of the fabric 6 during folding. The third direction reference... Figure 4 In the M direction, the third direction is set at an angle to the first plane.

[0033] like Figure 4 As shown, in some embodiments of this utility model, the pressing assembly 5 further includes: a first driving cylinder 502 disposed on the top surface of the substrate 1, the output end of the first driving cylinder 502 being connected to a first sliding mounting bracket 503, the first sliding mounting bracket 503 being slidably disposed above the substrate 1, a second driving cylinder 504 disposed on the top surface of the first sliding mounting bracket 503, the output end of the second driving cylinder 504 being connected to a second sliding mounting bracket 505, the second sliding mounting bracket 505 being slidably disposed above the substrate 1, a pressing plate 501 being slidably disposed on the second sliding mounting bracket 505, the first driving cylinder 502 being used to drive the pressing plate 501 to reciprocate along a second direction, and the second driving cylinder 504 being used to drive the pressing plate 501 to reciprocate along a third direction.

[0034] In this embodiment, to address the buffering process required for the first drive cylinder 502 to restart after driving the folding plate 301 to the third preset position S3, a first drive cylinder 502 and a second drive cylinder 504 are provided. The first drive cylinder 502 drives the first sliding mounting bracket 503 to reciprocate along the second direction, thereby driving the pressing plate 501 to reciprocate along the second direction. Its main purpose is to control the pressing plate 501 to move to the third preset position S3, aligning the edge of the first side of the pressing plate 501 with the folded edge 601 of the fabric 6. The second drive cylinder 504 drives the second sliding mounting bracket 505 to reciprocate along the second direction, thereby driving the pressing plate 501 to reciprocate along the second direction. Its main purpose is to control the pressing plate 501 to move to the sixth preset position, allowing the pressing plate 501 to quickly avoid the sewing area 4 within a limited time, ensuring smooth operation of the folding assembly 3 and effectively improving the folding efficiency of the fabric 6.

[0035] In some embodiments of this utility model, a first guide hole 509 extending along a third direction is provided on the first sliding mounting bracket 503, and a second guide hole 510 extending along a fourth direction is provided on the second sliding mounting bracket 505, wherein the fourth direction refers to... Figures 4 to 8 In the Z-direction, the fourth direction is perpendicular to the first and second directions, respectively. Additionally, a third sliding mounting bracket 506 is slidably mounted on the second sliding mounting bracket 505. A guide slide post 511 is mounted on the third sliding mounting bracket 506. The guide slide post 511 can simultaneously slide and connect the first guide hole 509 and the second guide hole 510. Through the simultaneous sliding engagement of the first guide hole 509 and the second guide hole 510 with the guide slide post 511, the reciprocating motion of the third mounting bracket in the third direction can be achieved, realizing the composite guidance and precise positioning of the pressing plate 501. Simultaneously, the simultaneous engagement of the guide slide post 511 with the first guide hole 509 and the second guide hole 510 can reduce wear caused by interference between components, helping to extend the service life of the overall fabric 6 folding mechanism.

[0036] In some embodiments of this utility model, a first slide rail 507 is provided on the substrate 1, a first guide groove is provided on the bottom surface of the first sliding mounting bracket 503, and a second guide groove is provided on the bottom surface of the second sliding mounting bracket 505. Both the first guide groove and the second guide groove are slidably connected to the first slide rail 507. By providing the first slide rail 507 on the substrate 1 and making the guide grooves at the bottom of the first sliding mounting bracket 503 and the second sliding mounting bracket 505 slidably connected to the first slide rail 507, the structure of the relevant parts of the pressing component 5 is more compact, saving installation space. Moreover, the first sliding mounting bracket 503 and the second sliding mounting bracket 505 share the first slide rail 507, which enables them to have a unified and high-precision motion reference, ensuring the coordination and relative positional accuracy of the first sliding mounting bracket 503 and the second sliding mounting bracket 505 during movement and reducing cumulative errors. Meanwhile, by sliding and engaging the first guide groove and the second guide groove with the first slide rail 507 respectively, the movement paths of the first sliding mounting bracket 503 and the second sliding mounting bracket 505 can be limited and corrected, effectively improving the movement accuracy of the pressing plate 501 in the second direction, thereby improving the folding accuracy of the fabric 6.

[0037] In some embodiments of this utility model, a third guide groove is provided on the third sliding mounting bracket 506, and a second slide rail 508 is provided on the third sliding mounting bracket 506. The third guide groove is slidably connected to the second slide rail 508. Through the sliding cooperation of the third guide groove and the second slide rail 508, the movement path of the third sliding mounting bracket 506 can be limited and corrected, further improving the movement accuracy of the pressing plate 501 in the third direction, so that the first side of the pressing plate 501 can finally be aligned with the folded edge 601, thereby improving the accuracy of the fabric 6 when folding.

[0038] In some embodiments of this utility model, the folding assembly 3 further includes: a third driving cylinder 302 disposed on the top surface of the substrate 1, the output end of the third driving cylinder 302 being connected to a fourth sliding mounting bracket 303, the fourth sliding mounting bracket 303 being slidably disposed above the substrate 1, and the fourth sliding mounting bracket 303 being connected to the folding plate 301. The third driving cylinder 302 can drive the folding plate 301 to reciprocate along the second direction. By directly disposing the third driving cylinder 302 on the top surface of the substrate 1 and driving the slidably disposed fourth sliding mounting bracket 303 with its output end, the folding plate 301 is driven to reciprocate precisely along the second direction, thereby forming a highly integrated and efficient linear drive structure, effectively improving the working efficiency of the overall fabric 6 folding mechanism.

[0039] Optionally, a third slide rail 304 is provided on the base plate 1, and a fourth guide groove is provided on the bottom surface of the fourth sliding mounting bracket 303. The fourth guide groove is slidably connected to the third slide rail 304. Through the sliding cooperation of the fourth guide groove and the third slide rail 304, the movement path of the fourth sliding mounting bracket 303 can be limited and corrected, effectively improving the movement accuracy of the folding plate 301 in the second direction, and further improving the folding accuracy of the fabric 6.

[0040] In some embodiments of this utility model, a limiting member 305 is provided on the substrate 1. The limiting member 305 is generally U-shaped. A third limiting part 306 is provided on the side of the fourth sliding mounting bracket 303 near the limiting member 305. The third limiting part 306 is located inside the limiting member 305. By controlling the movement range of the third limiting part 306 through the limiting member 305, the movement range of the fourth sliding mounting bracket 303 and the folding plate 301 in the second direction is precisely limited, thereby accurately controlling the folding size of the fabric 6.

[0041] In some specific embodiments, adjusting bolts 307 are respectively provided at both ends of the limiting member 305 in the second direction. By turning the adjusting bolts 307, the movement range of the third limiting part 306 in the second direction can be finely adjusted, thereby further precisely controlling the folding size of the fabric 6.

[0042] like Figures 5 to 8As shown, the working principle of this utility model is as follows: control the drive folding plate 301 to move to the first preset position S1, lay the fabric 6 on top of the folding plate 301, align the folded edge 601 of the fabric 6 with the edge of the first side of the folding plate 301, control the drive pressing plate 501 to move along the second direction, after the edge of the first side of the pressing plate 501 is aligned with the folded edge 601 of the fabric 6, control the drive pressing plate 501 to move downward along the third direction to the second preset position S2, so that the fabric 6 is pressed on the surface of the support plate 2, control the drive folding plate 301 to move along the second direction to the third preset position S3, so that the fabric 6 is folded, control the drive pressing plate 501 to move along the second direction to the fourth preset position S4, so that the pressing plate 501 avoids the sewing area 4, so that the fabric 6 can be sewn in subsequent sewing processes.

[0043] It should be noted that when manually placing the fabric 6, the folded edge 601 of the fabric 6 needs to be manually aligned with the edge of the first side of the folding plate 301. Furthermore, a sewing hole 201 is provided on the surface of the support plate 2, which extends along the first direction. The sewing area 4 is located at the position of the sewing hole. At this time, the sewing needle can pass through the sewing hole 201 to sew the folded fabric 6.

[0044] In addition to the fabric 6 folding mechanism described above, this utility model also provides a sewing device that includes the fabric 6 folding mechanism disclosed in the above embodiments. For the structure of other parts of the sewing device, please refer to the prior art, which will not be repeated here.

[0045] In summary, by controlling the position of the folding plate 301 in the second direction, the position of the folded edge 601 on the fabric 6 is precisely controlled, thereby flexibly adjusting the folding size of the fabric 6. Simultaneously, it can fold fabrics 6 of different sizes, effectively improving the compatibility of the fabric 6 folding component 3. Furthermore, by aligning the edge of the first side of the pressing plate 501 with the folded edge 601 of the fabric 6 and pressing the fabric 6, and then controlling the folding plate 301 to move along the second direction, the fabric 6 is precisely folded at the folded edge 601 position, effectively improving the positional accuracy of the fabric 6 during folding.

[0046] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0047] This article uses specific examples to illustrate the principles and implementation methods of this utility model.
