Description

Technical Field

[0001] This invention belongs to the field of sewing machine technology, specifically relating to a modular multi-functional sewing machine. Background Technology

[0002] Garment making involves processes such as design, cutting, and sewing. Sewing is usually done by sewing machine. Specifically, the feeding structure feeds the fabric to the pressing and folding structure, which folds the fabric edges. Then, the changing pressing structure moves the folded fabric to the sewing area for sewing.

[0003] Because the shapes of the fabric cut for the collar, cuffs, and pocket flaps of the garments are different, the folding of the fabric before sewing and the position of the sewing during the sewing process are different, and the specifications of the collar, cuffs, and pocket flaps of each garment are also different, it is generally necessary to change part of the sewing machine structure after sewing a certain shape and specification of fabric, and then adjust it after the change.

[0004] Specifically, it involves replacing parts such as pressure plates, inner pressure frames, and outer pressure frames that are compatible with the shape of the fabric. A large number of parts need to be replaced at one time, and the interfaces of the parts must be carefully aligned when replacing them. After replacement, the working module that installed the part needs to be debugged. The switching time consumed by sewing different fabrics is long and the efficiency is low. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0006] A modular multi-functional sewing machine includes a feeding moving module, a feeding module detachably fixed to the feeding moving module, a folding moving module, a folding module detachably fixed to the folding moving module, a three-axis moving module, a mold changing pressing module detachably fixed to the three-axis moving module, and a positioning structure disposed between the connecting modules. The folding module is used to fold the fabric edges, and the mold changing pressing module is used to press down the folded fabric and move the fabric to the sewing mechanism via the three-axis moving module.

[0007] Specifically, the positioning structure includes a positioning pin and a positioning plate, with the positioning plate having a positioning hole for the positioning pin to be inserted.

[0008] Specifically, the positioning pin has a V-shaped annular groove, and the positioning plate is equipped with a positioning cylinder whose output end can be inserted into the annular groove.

[0009] Specifically, the feeding moving module includes a feeding slide that moves in a direction under a driving force, and the feeding module includes a feeding back plate. The feeding back plate and the feeding slide are locked together by bolts and nuts.

[0010] Specifically, the feeding module also includes a tongue mold connected to the feeding back plate.

[0011] Specifically, the folding moving module includes a folding slide that moves in a direction under a driving force, and the folding module includes a folding back plate. The folding slide and the folding back plate are locked together by bolts and nuts, or the folding slide and the folding back plate are locked together on the same plate by bolts and nuts and thus fixed relative to each other.

[0012] Specifically, the folding module also includes a pressure plate assembly connected to the folding back plate and several telescopic components that are wrapped around the pressure plate assembly. The output end of the telescopic components extends toward the center of the pressure plate assembly to fold the edge of the fabric.

[0013] Specifically, the three-axis moving module includes a pressure slide that moves in a direction under driving force, and the mold changing pressure module includes a pressure back plate. The pressure slide and the pressure back plate are locked together by bolts and nuts.

[0014] Specifically, the mold changing pressing module further includes a pressing mold connected to the pressing back plate. The pressing mold is a pressing plate with holes to avoid the fabric to be sewn. Alternatively, the pressing mold includes a pressing frame connecting seat, an outer pressing frame, a module fixing plate, a pocket guard, an inner pressing frame, a telescopic plate, and a pocket pressing plate. The outer pressing frame is connected to the pressing back plate on the outside via the pressing frame connecting seat, and to the pocket guard on the inside via the module fixing plate. One end of the telescopic plate is connected to the pressing back plate, and the other end is connected to the inner pressing frame. The inner pressing frame is provided with a pocket pressing plate.

[0015] Specifically, the feeding moving module and / or folding moving module are provided with a Y-axis moving module, which is used to adjust the vertical distance between the feeding module and the folding module; the feeding moving module and / or folding moving module are provided with a Z-axis moving module, which is used to adjust the horizontal distance between the feeding module and the folding module.

[0016] The technical solution provided by this invention has the following advantages compared with the prior art:

[0017] 1. The parts of the sewing machine that adapt to the shape of the fabric are made independent and modular. When switching to different fabrics, the corresponding modules are replaced as a whole, which improves the adaptability of the sewing machine, avoids the need for parts adjustment, and only requires the replacement of 1-3 modules per switch, reducing the number of replacement operations, shortening the time spent on switching, and reducing the workload.

[0018] 2. It has an automatic positioning function, which improves the speed of module assembly and disassembly, reduces module assembly deviation, and thus avoids overall module debugging, further saving time and improving efficiency. Attached Figure Description

[0032] Example 1

[0033] like Figures 1 to 2 As shown, the modular multi-functional sewing machine includes a feeding mechanism 20 installed on a platform 10, a folding mechanism 30 arranged vertically in the feeding mechanism 20, a mold changing and pressing mechanism 40, a sewing mechanism 50, and a support 60.

[0034] The feeding mechanism 20 includes a feeding moving module 21 and a feeding module 22 detachably fixed to the feeding moving module 21. The feeding moving module 21 includes a Y-axis slide plate 211, a Y-axis linear guide rail 212 disposed on the Y-axis slide plate 211, a first sliding seat 213 fixedly connected to the bracket 60, a first drive structure, a second drive structure, a Z-axis guide rail 214 fixedly mounted on the Y-axis slide plate 211, and a feeding slide 215 with a shaft hole. The first drive structure is used to drive the first sliding seat 213 to move along the Y-axis linear guide rail 212. The second drive structure is used to drive the feeding slide 215 to rise and fall along the Z-axis guide rail 214. The Y-axis linear guide rail 212 is disposed on the elongated Y-axis slide plate 211, and the length of the first sliding seat 213 is shortened to avoid the tongue mold 222.

[0035] The feeding module 22 includes a feeding back plate 221 with another shaft hole and a tongue mold 222 connected to the feeding back plate 221. The two shaft holes are aligned with each other and locked together by bolts and nuts. In this embodiment, the shaft hole of the feeding back plate 221 can be a strip hole along the vertical direction. After loosening the nut, the height of the tongue mold 222 relative to the platform 10 can be adjusted.

[0036] like Figures 3 to 5As shown, the folding mechanism 30 includes a folding moving module 31 and a folding module 32 detachably fixed to the folding moving module 31.

The third drive structure is used to drive the second sliding seat 313 to move along the Y'-axis linear guide rail 312. The Y-axis guide rail and the Y'-axis guide rail are used to adjust the feeding module 22 and the folding module 32 to move vertically, ensuring that they can overlap / misalign. The second sliding seat 313 is located above the first sliding seat 213. The fourth drive structure is used to drive the folding slide 315 to rise and fall along the Z'-axis guide rail 314. The Z-axis guide rail 214 and the Z'-axis guide rail 314 are used to adjust the feeding module 22 and the folding module 32 to move vertically, ensuring that they can overlap / misalign.

[0038] The folding module 32 includes a folding back plate 321, a pressure plate assembly connecting the folding back plate 321, and several telescopic components arranged around the pressure plate assembly. The output ends of the telescopic components extend towards the center of the pressure plate assembly to fold the fabric edge. The pressure plate assembly includes a support plate 325, a pressure plate 326, and an L-shaped plate 327. The telescopic components are folding cylinders 324, with several cylinders arranged around the edge of the pressure plate 326. The bottom end of the L-shaped plate 327 is fixedly connected to the pressure plate 326, and the top end is fixedly connected to the support plate 325. There is a gap in height between the support plate 325 and the pressure plate 326, and the support plate 325 is short and does not cover the middle and front end of the pressure plate 326. Specifically, the tongue mold 222 extends from the gap to above the pressure plate 326, and the output end of the folding cylinder 324 is adjusted to be lower than the height of the tongue mold 222 but higher than the height of the fabric edge. The output end extends horizontally towards the center of the fabric, pressing down the fabric edge, and then... The fabric edge is folded under the tongue mold 222 to complete the fabric folding. Both the folding back plate 321 and the folding slide 315 have connecting holes, and the support plate 325 has a through hole. The connecting hole of the folding back plate 321 and the through hole of the support plate 325 are aligned with each other and fixed by screwing in a nut after passing through the bolt hole. The connecting hole of the folding slide 315 and another through hole of the support plate 325 are aligned with each other and fixed by screwing in a nut after passing through the bolt hole, so that the folding module 32 and the folding moving module 31 are relatively fixed. A positioning plate 34 is provided between the folding back plate 321 and the folding slide 315. The positioning plate 34 has a positioning hole 33 with an opening facing the folding back plate 321. The folding back plate 321 is provided with a positioning pin 35 that is inserted into the positioning hole 33. The positioning pin 35 has a V-shaped annular groove 36. The positioning plate 34 is equipped with a positioning cylinder 37 whose output end can be inserted into the annular groove.

[0039] like Figures 6 to 7As shown, the mold changing and pressing mechanism 40 includes a three-axis moving module 41 and a mold changing and pressing module 42 detachably fixed on the moving module.

The three-axis moving module 41 includes a pressing slide 411 and a guide structure and a driving structure for driving the pressing slide 411 to move along the X, Y and Z directions.

[0040] The pressing slide 411 includes a main slide 412 and auxiliary slides 413 distributed on both sides of the main slide 412. Each slide is slidably connected to an independently set longitudinal track. The mold changing pressing module 42 includes a pressing back plate 421 and a pressing mold 422 connected to the pressing back plate 421. The pressing mold 422 includes a pressing frame connecting seat 423, an outer pressing frame 424, a module fixing plate 425, a pocket guard 426, an inner pressing frame 427, a telescopic plate 428, and a pocket press. The plate 429, wherein the folding back plate 321 includes a main back plate connected to the main slide 412 and a secondary back plate connected to the secondary slide 413. The two ends of the U-shaped outer pressure frame 424 are respectively connected to a secondary back plate through a pressure frame connecting seat 423. The inner side of the outer pressure frame 424 is connected to the pocket guard 426 through the module fixing plate 425. One end of the telescopic plate 428 is connected to the main back plate, and the other end is connected to the inner pressure frame 427. The inner pressure frame 427 is provided with a pocket pressure plate 429.

[0041] The pressure slide 411 and the pressure back plate 421 are provided with relatively aligned locking holes, and the two locking holes are locked together by bolts and nuts.

[0042] In this embodiment, by replacing the feeding module 22, folding module 32, and mold changing and pressing module 42 with different functions, the bag attaching machine can have the functions of attaching bags, bag caps, shoulder covers, or cuffs.

[0043] Example 2

[0044] like Figure 8 The difference between this embodiment and Embodiment 1 is that the folding module 32 includes a folding back plate 321, an upper outer pressure frame 322 and a lower outer pressure frame 323 connecting the folding back plate 321, and several telescopic components arranged around the upper outer pressure frame 322. The upper outer pressure frame 322 and the lower outer pressure frame 323 are pressure plate assemblies. The tongue mold 222 extends between the upper outer pressure frame 322 and the lower outer pressure frame 323. Specifically, the cylinder output end is lower than the height of the tongue mold 222 and higher than the height of the fabric edge. The cylinder output end extends towards the middle of the two outer pressure frames 424, presses down on the fabric edge, and continues to extend, folding the fabric edge below the tongue mold 222 to complete the fabric edge folding. Both the folding back plate 321 and the folding slide 315 have connecting holes. The two connecting holes are aligned with each other and fixed by screwing nuts after passing through the bolt holes.

[0045] Example 3

[0046] like Figure 9 The difference between this embodiment and Embodiment 2 is that the pressing mold 422 is a plate, which avoids the sewing part of the sewing mechanism 50 that is used to sew the fabric. This means that a long and thin hollow track is opened on the plate to expose the area of ​​the fabric to be sewn. The needle of the sewing mechanism 50 is inserted into the hollow track and sewn the fabric under its guidance.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
