Description

Technical Field

[0001] This invention relates to the field of bag processing technology, and in particular to a pressing and sewing device for bag processing. Background Technology

[0002] Bags and luggage play an irreplaceable role in meeting people's daily and fashion consumption needs. Moreover, with economic development, China's bag and luggage consumption is increasing every year, and bags and luggage are becoming one of the most promising industries after clothing, textiles, and footwear.

[0003] The basic stitching types for bags and leather goods include: straight seam, overlapping seam, split seam, button seam, patchwork seam, binding seam, piping seam, and saddle stitch. Among these, the split seam involves placing two pieces of leather face to face and sewing them along one edge from the back at fixed intervals. After sewing, the leather is separated and pressed together. Excess seam allowance can be glued or sewn in place. It's important to note that if the leather is thick, the seam allowance needs to be thinned, i.e., using a small chisel to reduce the seam allowance to a suitable thickness for folding. This involves folding the edge of the leather part up to allow for stitching or decorative stitching (such as...) at the folded edge. Figure 1 As shown, S1 sews the two leather pieces together after the edges are trimmed; S2 separates and flattens the excess pressed edges to both sides; S3 sews the two pressed edges together. In current operations, most methods involve manually folding and flattening the two edges before sewing the decorative lines on both sides. On the one hand, manual folding results in uneven edges due to uneven force applied each time; on the other hand, manual operation increases the labor intensity for workers. Therefore, it is necessary to develop a device to assist in opening, pressing, and sewing. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a pressing and sewing device for bag processing. This device separates and flattens the folded edges of the two seam edges, and then sews them in the subsequent process, replacing manual labor, reducing labor intensity and improving production efficiency.

[0005] To achieve the above objectives, in a first aspect, the present invention provides a pressing and sewing device for bag processing, comprising: a work platform, and a separating component located above the work platform;

[0006] The bottom surface of the edge-separating component is parallel to the working platform surface, with a narrow space between them to facilitate the passage of the edge-separating component. The feed end of the edge-separating component is vertically provided with a pointed tip for separating the two edges, and both sides of the pointed tip are provided with arc-shaped concave surfaces for guiding the edges to both sides and separating them to the horizontal.

[0007] The bottom plane of the edge-separating component is provided with flattening rollers that rotate around a horizontal axis on both sides of the tip, and a first rotation drive for driving the flattening rollers to rotate; the axis of the flattening rollers is set at an acute angle to the feeding direction, and when it rotates, it is used to guide the seam edge and press it towards both sides of the feeding direction;

[0008] The work platform is also provided with a first sewing machine for sewing the first dividing edge a and a second sewing machine for sewing the second dividing edge b, located directly behind the dividing edge component.

[0009] Furthermore, the axis of the flattening roller is set at a 45° angle to the feeding direction.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0033] Please see Figures 1-9 This invention provides a pressing and sewing device for bag processing, including: a work platform 1, and a splitting component 2 located above the work platform 1;

[0034] The bottom surface of the edge-separating component 2 is parallel to the surface of the working platform 1, and there is a narrow space 3 between them to facilitate the passage of the edge-separating component. The feed end of the edge-separating component 2 is vertically provided with a pointed tip 4 for separating the two edges, and both sides of the pointed tip 4 are provided with arc-shaped concave surfaces 5 for guiding the edges to both sides and separating them to the horizontal.

[0035] The bottom plane of the edge-separating component 2 is provided with flattening rollers 6 that rotate around a horizontal axis on both sides of the tip 4, and a first rotation drive for driving the flattening rollers 6 to rotate; the axis of the flattening rollers 6 is set at an acute angle to the feeding direction, and when it rotates, it is used to guide the seam edge and press it towards both sides of the feeding direction; the flattening rollers 6 on both sides are arranged in an inverted V-shape with the front end open and the rear ends converged together on both sides of the bottom of the edge-separating component 2.

[0036] The work platform 1 is located directly behind the edge-separating component 2, and a first sewing machine 20 for sewing the first pressure seam a and a second sewing machine 21 for sewing the second pressure seam b are also arranged in sequence.

[0037] In practical use, the two sewn leather pieces are opened and fed between the bottom surface of the edge-separating component 2 and the surface of the work platform 1. The edge-separating strip is manually separated and fed to the tip 4. Under the action of the arc-shaped concave surface 5, the flanges on both sides are pressed down. At the same time, when passing through the flattening roller 6, the flattening roller 6 rotates under the drive of the first rotation, which then evenly spreads and flattens the flanges on both sides of the two leather pieces to both sides, while conveying them along the feeding direction to avoid wrinkling. The flattened flanges are flush with the curved edges of the two leather pieces, ensuring the quality of the product after subsequent secondary sewing. Understandably, this replaces manual labor, reduces labor intensity, and improves production efficiency.

[0038] Then, when the first sewing machine 20 passes through, its needle sews the first dividing seam edge a, and the second sewing machine 21 sews the second dividing seam edge b, so that the two seam edges are neat.

[0039] Preferably, the axis of the flattening roller 6 is set at a 45° angle to the feeding direction. This angle setting is most reasonable, as it evenly spreads and flattens the flanges on both sides of the two pieces of leather while conveying them along the feeding direction to avoid wrinkling.

[0040] Preferably, the working platform 1 is provided with a bracket 7 for mounting the edge-separating component 2. The edge-separating component 2 has a vertically extending slot 8 and is fastened to the bracket 7 by bolts passing through the slot 8. The edge-separating component 2 can move vertically within the slot 8 to adjust the thickness of the pressed leather, which is suitable for the production and processing of different types of leather.

[0041] Preferably, one end of the flattening roller 6 is embedded and mounted on the edge-separating component 2 via a sliding bearing 9, and the other end of the roller is also mounted with the same sliding bearing 9, and is detachably mounted on the side of the edge-separating component 2 via a fixing bracket 10. This structure is reasonable and facilitates replacement and installation.

[0042] Preferably, the first rotation drive includes a first motor 11 disposed on the edge-separating component 2 and a first gear transmission assembly 12, wherein the output end of the first motor 11 is connected to the end of the flattening roller 6 via the first gear transmission assembly 12. This structure is compact.

[0043] Preferably, the working platform 1 is further equipped with a pressure roller 13 that rotates around a horizontal axis. The end of the pressure roller 13 is connected to a second rotary drive transmission. When it rotates, it is used to press the material onto the working platform 1 and convey it along the feeding direction. This facilitates pressing down the leather and prevents it from moving around randomly.

[0044] Preferably, the second rotary drive transmission includes a second motor 14 mounted on the work platform 1 and a second transmission assembly 15, wherein the output end of the second motor 14 is connected to the end of the pressure roller 13 via the second transmission assembly 15. The second transmission assembly 15 can be a chain drive assembly or a toothed belt drive assembly.

[0045] Preferably, the work platform 1 is provided with a first frame 22 for mounting a first sewing machine 20. The first frame 22 is provided with a first slot 23 in the horizontal direction. The first sewing machine 20 is fastened to the first slot 23 by a first bolt. The first sewing machine 20 can be adjusted by moving in the first slot 23, that is, in the width direction perpendicular to the feed, thereby adjusting the position of the hem stitching.

[0046] Preferably, the work platform 1 is provided with a second frame 24 for mounting a second sewing machine 21. The second frame 24 is provided with a second slot 25 in the transverse direction. The second sewing machine 21 is fastened to the second slot 25 by a second bolt. The second sewing machine 21 can be adjusted by moving in the second slot 25, that is, in the direction perpendicular to the width of the feed, thereby adjusting the position of the hem stitching.
