Description

Technical Field

[0001] This utility model relates to the field of sewing, and in particular to a slanted pocket sewing device. Background Technology

[0002] Sew the slanted pockets inside the trousers. The sewn pocket pieces look like... Figure 1 As shown, it has a single curved seam and a double U-shaped seam.

[0003] Sewing devices related to related technologies, such as Figure 2 As shown, it includes a frame 1, a worktable 2, a three-axis displacement drive platform 3, a pocket template 8, and a sewing machine 6. The three-axis displacement drive platform 3 is movably mounted on the frame 1 and drives the pocket template 8 to move. The pocket template 8 has two sewing grooves: an arc-shaped single-sided seam and a U-shaped double seam. The sewing machine 6 is fixedly mounted on the worktable 2.

[0004] Because the sewing machine needs to sew the pocket piece along the sewing groove on the pocket template, the distance between the sewing machine's needle and the base is L1 due to the placement and size of the sewing machine. The minimum distance required for sewing is L2. If L1 is less than L2, the pocket template will press against the base of the sewing machine during the sewing process, preventing it from moving forward and thus making it impossible to complete the sewing of the pocket piece.

[0029] The following is in conjunction with the appendix Figures 3-7 This application will be described in further detail to make the technical solution of this application easier to understand and master.

[0030] This application discloses a slanted pocket sewing device.

[0031] Reference Figure 1 This embodiment of a slanted pocket panel 9 sewing device includes a frame 1, a worktable 2, a three-axis displacement drive platform 3, a first template 41, a second template 42, an XZ axis displacement drive platform 5, and a sewing machine 6. The first template 41 has a first sewing groove 411 with an arc-shaped single-sided seam, and the second template 42 has a second sewing groove 421 with a U-shaped double seam.

[0032] Reference Figure 1The worktable 2 is set on the frame 1, the sewing machine 6 is set on the worktable 2, the three-axis displacement drive platform 3 is movably assembled on the frame 1, and can move along the preset X, Y and Z three-axis displacement trajectory. The first template 41 is installed on the three-axis displacement drive platform 3.

[0033] Reference Figure 1 The XZ axis displacement drive platform 5 is set on the three-axis displacement drive platform 3 and can move along the preset X and Z displacement trajectories. The second template 42 is installed on the XZ axis displacement drive platform 5.

[0034] Reference Figure 1 The original pocket template 8 is split into a first template 41 with a first sewing groove 411 and a second template 42 with a second sewing groove 421. The templates are driven independently by a three-axis displacement drive platform 3 and an XZ-axis displacement drive platform, respectively. This makes the distance between the first sewing groove 411 and the second sewing groove 421 adjustable. By adjusting the relative distance between the two templates, the templates can avoid the base of the sewing machine 6, effectively solving the problem of interference between the templates and the sewing machine 6 and ensuring the smooth progress of the sewing process.

[0035] Reference Figure 1 The second template 42 is located on the side of the first template 41 closest to the sewing machine 6. This is more in line with operating habits. The first template 41 and the second template 42 first press down on the pocket piece 9 at the normal sewing distance. Then, the sewing machine 6 first sews the U-shaped double seam on the second template 42. Then, the XZ axis displacement drive platform 5 drives the second template 42 to rise first, move closer to the first template 41, and then descend to press down on the pocket piece 9. Then, the sewing machine 6 sews the curved single-sided seam on the first template 41.

[0036] Reference Figure 1 The worktable 2 has a feeding area 21 and a sewing area 22. A three-axis displacement drive platform 3 drives the first template 41 and the second template 42 to move back and forth between the feeding area 21 and the sewing area 22. Several through holes 23 are opened on the worktable 2 at the position of the feeding area 21. An adsorption component is provided below the worktable 2 directly opposite the feeding area 21. The adsorption component can be a negative pressure fan or a negative pressure pump.

[0037] Reference Figure 1 The workbench 2 is divided into a feeding area 21 and a sewing area 22, which separates the feeding and sewing processes and improves the continuity of the operation. The through hole 23 of the feeding area 21 cooperates with the adsorption component below to firmly adsorb the pocket piece 9 to be processed, avoid the fabric shift during feeding and sewing, and ensure sewing accuracy.

[0038] Reference Figure 1The three-axis displacement drive platform 3 includes an X-axis slide 31, a Y-axis slide 32, a Z-axis slide 33, a first drive component 34, a second drive component 35, and a third drive component. The X-axis slide 31 is slidably connected to the frame 1 along the X-axis direction, and the first drive component 34 drives the X-axis slide 31 to move. The Y-axis slide 32 is slidably connected to the X-axis slide 31 along the Y-axis direction, and the second drive component 35 drives the Y-axis slide 32 to move. The Z-axis slide 33 is slidably connected to the Y-axis slide 32 along the Z-axis direction, and the third drive component drives the Z-axis slide 33 to move. The first template 41 and the XZ-axis displacement drive platform 5 are both set on the Z-axis slide 33.

[0039] Reference Figure 1 It provides a flexible three-axis movement trajectory for the first template 41, which can accurately drive the first template 41 and the second template 42 to the required sewing position; at the same time, the first template 41 and the XZ axis displacement drive platform are integrated on the Z axis slide to ensure the basic coordination of their movement.

[0040] Reference Figure 1 The first drive component 34 and the second drive component 35 can be any drive device. In this embodiment, a motor drives the gear teeth to rotate, the gear teeth drive the belt drive, and the belt drives the first unit 53 or the second unit 54 to move. The third drive component includes two third cylinders 36, which are respectively fixedly installed on both sides of the Y-axis slide 32. The piston rods of the two third cylinders 36 are vertically downward and fixed at both ends of the bottom of the Z-axis slide 33.

[0041] Reference Figure 1 The XZ axis displacement drive platform 5 includes a first cylinder 51, a second cylinder 52, a first stage 53, and a second stage 54. The first stage 53 slides along the X-axis direction on the Z-axis slide 33. The first cylinder 51 is fixedly mounted on the Z-axis slide 33, and one end of its piston rod is located on the first stage 53. The second stage 54 slides along the Y-axis direction on the first stage 53. The second cylinder 52 is fixedly mounted on the first stage 53, and one end of its piston rod is located on the second stage 54. The second template 42 is mounted on the second stage 54.

[0042] Reference Figure 1 The first cylinder 51 and the second cylinder 52 drive the first machine 53 and the second machine 54 to slide, respectively, so as to realize the rapid and precise displacement of the second template 42 in the X and Y directions. The cylinder drive has a fast response and can adjust the position of the second template 42 in time to avoid interference from the sewing machine 6. The structure is simple and easy to maintain.

[0043] Reference Figure 1 When the piston rod of the second cylinder 52 extends, the first template 41 and the second template 42 are located on the same horizontal plane.

[0044] Reference Figure 1When the piston rod of the second cylinder 52 extends, the first template 41 and the second template 42 are on the same horizontal plane, so that the pocket piece 9 remains flat on the two templates, improving the sewing quality of the pocket piece 9.

[0045] Reference Figure 1 It also includes an L-shaped first connecting frame 71 and a second connecting frame 72. The first template 41 is fixedly connected to the Z-axis slide 33 via the first connecting frame 71, and both ends of the first connecting frame 71 are fixed to the first template 41 and the Z-axis slide 33 respectively with screws. The second template 42 is fixedly connected to the second stage 54 via the second connecting frame 72, and both ends of the second connecting frame 72 are fixed to the second template 42 and the second stage 54 respectively with screws.

[0046] Reference Figure 1 This not only ensures the stability of the first template 41 and the second template 42 installation and prevents template displacement caused by sewing vibration, but also facilitates the disassembly and replacement of the first template 41 and the second template 42, which can be adapted to the sewing needs of different specifications of slanted pocket pieces 9 and enhance the versatility of the device.

[0047] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
