Technical Field

[0002] In the process of garment processing, bag opening equipment (also called bag opening machine, bag opening sewing machine, etc.) is an indispensable auxiliary processing machine, which is mainly used to form pockets at specific positions of garments. The conventional practice is to process the bag mouth and bag lip separately first, and then sew the bag lip to the bag mouth to complete the bag opening.

[0003] The existing bag opening equipment usually includes a cutting device, a sewing device, a folding and pressing frame device, and a folding device adapted to the folding and pressing frame device. The sewing device is used for sewing, and the cutting device is used for cutting the fabric. The fabric is usually constrained by the folding and pressing frame device through the cooperation of the folding device and the folding and pressing frame device to form a long strip of bag opening on the fabric. Figure 3 The existing bag opening process generally includes: Step 1, determining the pocket opening area on the fabric where the pocket opening needs to be sewn, such as Figure 1 As shown, the size of the pocket area is usually consistent with the size of the pocket; step 2, using a cutting device to cut a seam in the pocket area that fits the required pocket, thereby forming four pocket edge pieces, such as Figure 2 As shown; Step 3, insert the folding device into the bag opening area, fold each bag edge piece to the inner side of the bag opening through the folding device to form a folded edge, and use the folding frame pressing device to press the bag edge piece to form a bag opening of the desired shape, such as Figure 3 As shown; Step 4, directly use the sewing device to sew the folded edge according to actual needs, or first stack the bag lip or zipper or cloth piece and other sewing objects at the bag opening and then use the sewing device to sew the folded edge to complete the bag opening work.

[0004] However, the folding frame pressing device of the existing bag opening equipment is only suitable for bag openings of fixed sizes. For example, Chinese patent CN111575926A discloses a bag opening machine for processing clothing bag openings, Chinese patent CN 112430916 A discloses a continuous production clothing bag opening machine, and Chinese patent CN 113622101 B discloses a bag opening machine and processing technology for secondary sewing of pockets. When the size of the bag opening changes, it is necessary to adaptively replace the folding frame pressing device of the corresponding size, resulting in poor versatility of the existing bag opening equipment and being not conducive to automation, which needs to be solved urgently.

[0050] The present embodiment provides a folding frame pressing device, including a carrier 21, a first matching unit 22, a second matching unit 23 and a control module, wherein:

[0051] The supporting frame 21 mainly plays a bearing role. For the convenience of description, in this embodiment, the two mutually perpendicular horizontal directions of the supporting frame 21 can be referred to as the first direction and the second direction, and the thickness direction of the supporting frame 21 can be referred to as the vertical direction. Fig.13 As shown, the first direction, the second direction and the vertical direction are perpendicular to each other.

[0052] The first matching unit 22 is disposed on the supporting frame 21.

At the same time, in this embodiment, the first adjustment module is connected to the matching module 24 by transmission, so that the first adjustment module can be used to drive at least one matching module 24 to move along the first direction, so that the spacing L between the two matching modules 24 along the first direction can be adjusted by the first adjustment module, and the spacing L corresponds to the length of the bag opening 11, and the spacing L can be adjusted by the first adjustment module, so that the bag openings 11 of different lengths can be automatically adapted to meet the bag opening requirements of the bag openings 11 of different lengths.

[0053] The second matching unit 23 is also disposed on the supporting frame 21. Fig.10 and Fig.11 As shown, in this embodiment, the second matching unit 23 includes a second adjustment module, two matching modules 24 adapted to the folding structure 83 in the folding device 8, and the two matching modules 24 are arranged relatively along the second direction, so that there is a spacing between the two matching modules 24, and the spacing is used to adapt to the width of the bag opening 11. At the same time, in this embodiment, the second adjustment module is connected to the matching module 24 by transmission, so that the second adjustment module can be used to drive at least one matching module 24 to move along the second direction, so that the spacing W between the two matching modules 24 along the second direction can be adjusted by the second adjustment module, and the spacing W corresponds to the width of the bag opening 11, and the spacing W can be adjusted by the second adjustment module, so that the bag openings 11 of different widths can be adapted to meet the bag opening requirements of the bag openings 11 of different widths.

[0054] The first matching unit 22 and the second matching unit 23 are respectively connected to the control module so as to be uniformly controlled by the control module. In implementation, the control module can be implemented by existing technologies, including but not limited to existing controllers or processors. In implementation, the matching module 24 of the first matching unit 22 can be arranged between the two matching modules 24 of the second matching unit 23, such as Fig.13 and Fig.14 As shown, not only the layout is more reasonable, the action coordination is more efficient; but also the four matching modules 24 can be together to form a central plug 26 adapted to the bag openings 11 of different sizes, such as Fig.13 and Fig.14 As shown, the folding frame device 2 can automatically adjust the distance between the two matching modules 24 according to the size of the bag opening 11, so as to meet the bag opening requirements of bags 11 of different sizes, and significantly improve the versatility. When in use, the folding device 8 in the bag opening device can also be inserted into the fabric 1 through the central insertion port 26.

[0055] In implementation, the matching module 24 may include a seat body 3, a pulling mechanism and a pressing mechanism, wherein the seat body 3 mainly plays a bearing role; the pressing mechanism includes a pressing component 36 and a pressing power 35 connected to the seat body 3, and the pressing power 35 is connected to the pressing component 36 in a transmission manner, so that the pressing component 36 is driven by the pressing power 35 to press the bent bag edge piece 14 upward. In implementation, the pressing component 36 can be made of a plate, which can be a flat plate or a bent plate with a bend, such as Figure 8 or Fig.12 As shown. The pulling mechanism includes a pulling component 34 and a pulling power 33 connected to the seat body 3. The pulling power 33 is connected to the pulling component 34 in a transmission manner. The pulling component 34 can be arranged along the first direction or the second direction so as to move along the first direction or the second direction under the drive of the pulling power 33. During assembly, at least a part of the pulling component 34 is arranged above the upper pressing component 36 so as to cooperate with the upper pressing mechanism 6. During implementation, the pulling component 34 is configured to adapt to the folding device 8. The pulling component 34 can be made of a plate material, which can be a flat plate or a bent plate with a bend, such as Figure 8 or Fig.12 As shown. The pulling power 33 and the pressing power 35 are respectively connected to the control module for automatic and precise control. In the process of opening the bag, the pulling power 33 is used to drive the pulling component 34 to move to position one in the direction of the other set of matching modules 24 corresponding thereto, so as to form a folding match with the folding structure 83 on the side of the folding device 8 at position one, and press the bag edge piece 14 on the corresponding side against the folding device 8, so that the bag edge piece 14 is bent, as shown in FIG. Fig.18 Then, the upper pressing force 35 can drive the upper pressing member 36 to press the bent bag edge piece 14, as shown Fig. 20 As shown, in order to perform sewing or other operations later; in addition, the pulling power 33 is also used to drive the pulling component 34 to move to position two in a direction away from the other set of matching modules 24 corresponding thereto. In this process, the pulling component 34 gradually moves away from the folding structure 83 on the corresponding side, so that the pulling component 34 can gradually withdraw from the folding device 8. At position two, the pulling component 34 can have completely withdrawn from the folding structure 83 of the folding device 8, so as to perform sewing along the edge of the bag opening 11 later. In this embodiment, by configuring a pulling mechanism in the matching module 24, and configuring a pulling power 33 and a pulling component 34 connected to the pulling power 33 in the pulling mechanism, the pulling mechanism can form a folding cooperation with the folding device 8, which can not only form a new folding process, but also meet the folding requirements of fabrics 1 of different thicknesses and bag openings 11 of different sizes, ensuring that fabrics 1 of different thicknesses and bag openings 11 of different sizes can achieve better folding effects, and is conducive to realizing automatic folding.

[0056] During implementation, the matching module 24 in the first matching unit 22 may be the same as or different from the matching module 24 in the second matching unit 23 .

[0057] For the first matching unit 22, during implementation, a set of first adjustment modules can be configured for each of the two matching modules 24, or a set of first adjustment modules can be used to drive the two matching modules 24 at the same time. Figure 4-Figure 9 As shown, the first adjustment module may include a first adjustment power 221 and a first moving mechanism 222 , the first adjustment power 221 is transmission-connected to the first moving mechanism 222 , the first moving mechanism 222 is transmission-connected to the matching module 24 , and the control module is connected to the first adjustment power 221 . The first adjusting power 221 can adopt a stepping motor or a servo motor, etc. The first moving mechanism 222 is arranged along the first direction. The first moving mechanism 222 can adopt a belt transmission mechanism, a gear-rack 43 transmission mechanism or a screw-nut transmission mechanism, etc. In one embodiment, the two matching modules 24 can be connected to the support frame 21 through a linear guide rail 25 arranged along the first direction, so that the matching module 24 has the freedom to move along the first direction; at the same time, a set of first adjusting modules can be configured for the two matching modules 24 respectively. The first moving mechanism 222 in the first adjusting module adopts a screw-nut transmission mechanism. The screw in the screw-nut transmission mechanism is rotatably installed on the support frame 21 and arranged along the first direction. The nut in the screw-nut transmission mechanism is threadedly connected to the screw and fixedly connected to the seat 3 of the matching module 24. The first adjusting power 221 is connected to the screw transmission, and the matching module 24 is driven to move linearly along the first direction by driving the screw to rotate, thereby achieving the purpose of adjusting the distance between the two matching modules 24. It can be understood that the first adjustment module is also configured with a design to prevent the nut from rotating with the screw rod, which is a prior art and will not be explained here with examples.

[0058] In another preferred implementation manner provided in the present embodiment, the two matching modules 24 can be driven to move synchronously in the opposite direction along the first direction by the first adjusting power 221. This not only allows the distance L between the two matching modules 24 to be quickly adjusted to adapt to bag openings 11 of different lengths, but also helps to simplify the control and folding process and improve the matching accuracy. In implementation, when the two matching modules 24 are respectively configured with a set of independent first adjusting modules, the two sets of first adjusting modules can be electrically connected to the control module respectively, so that the control module can be used to control the two first adjusting modules to move synchronously in the opposite direction. When the two matching modules 24 share a set of first adjusting modules, the first adjusting power 221 can be used to automatically control the two matching modules 24 to move synchronously in the opposite direction. At this time, for example, Figure 4-Figure 9As shown, the first moving mechanism 222 includes a synchronous gear 41 and two symmetrically arranged transmission components 42. The transmission components 42 can be preferably constructed in an L shape. The two transmission components 42 are respectively connected to the carrier 21 through linear guides 25 arranged along the first direction, so that the transmission components 42 have the freedom to move along the first direction; the two matching modules 24 in the first matching unit 22 are respectively connected to the two transmission components 42, as shown in FIG. Figure 4-Figure 9 As shown, the two transmission components 42 are respectively configured with racks 43 adapted to the synchronous gear 41, the racks 43 of the two transmission components 42 are respectively meshed with the synchronous gear 41, and the synchronous gear 41 is located between the two racks 43, and the first adjustment power 221 can be fixedly arranged on the carrier 21 and connected to the synchronous gear 41 in transmission, as shown in FIG. Fig. 9 As shown, the rotation center of the synchronous gear 41 can be along the vertical direction, so that the two transmission components 42 can be driven to move synchronously in the opposite direction along the first direction at the same time through the first adjustment power 221, which can not only effectively improve the adjustment efficiency, but also ensure the movement accuracy of the two matching modules 24, which is conducive to improving the adjustment accuracy.

[0059] As an example, in the first matching unit 22, the pulling power 33 may preferably be a cylinder, such as Figure 6 and Figure 8 As shown, one end of the cylinder can be connected to the seat body 3, and the other end is connected to the drawer 34. The cylinder is arranged along the first direction so that the cylinder can be extended and retracted along the first direction. The position of the drawer 34 along the first direction is adjusted by the extension and retraction of the cylinder. In order to improve the movement accuracy of the drawer 34 and make the structure more compact and smaller in size. In implementation, the seat body 3 is configured with a guide groove 31 along the first direction, such as Figure 6 As shown, the side of the pull-out component 34 is movably constrained in the guide groove 31, so that the guide groove 31 is utilized to guide the pull-out component 34. In addition, during implementation, the pull-out power 33 may also be an electric push rod or a hydraulic cylinder.

[0060] As an example, the upper pressing member 36 can be hinged to the seat body 3, such as Figure 8 As shown, the upper pressing member 36 can rotate around the hinge shaft 39; the upper pressing power 35 can also preferably use a cylinder, one end of the cylinder is connected to the seat body 3, and the other end is connected to the pull rod 38, and one end of the pull rod 38 is limited and constrained to one end of the upper pressing member 36, as shown in FIG. Figure 8As shown, the cylinder is telescopic in the vertical direction so that the cylinder can be used to drive the pressing part 36 to rotate, so that the principle of the lever can be used to clamp or loosen the bag edge piece 14, which not only makes the structure of the first matching unit 22 more compact and smaller, but also can better adapt to the folding device 8 and form a folding match suitable for different lengths with the folding device 8. In addition, during implementation, the pulling power 33 can also be an electric push rod or a hydraulic cylinder. In the first matching unit 22, the distance between the two pulling parts 34 at the second position can be used as the initial distance L between the two matching modules 24 along the first direction. Of course, the distance between the two pressing parts 36 can also be used as the distance L between the two matching modules 24 along the first direction.

[0061] In order to make the two matching modules 24 in the first matching unit 22 move strictly along the first direction, during implementation, the seat body 3 can also be connected to the carrier 21 through a linear guide rail 25. Figure 6-Figure 8 As shown, the seat body 3 is connected to a guide rod 37 arranged along the first direction, and the support frame 21 is provided with a guide hole 32 arranged along the first direction. The guide rod 37 and the guide hole 32 constitute a moving pair along the first direction, so that the seat body 3 is guided to move along the first direction through the cooperation between the guide rod 37 and the guide hole 32.

[0062] Similarly, for the second matching unit 23, in a preferred embodiment, a set of second adjustment modules can be configured for each of the two matching modules 24, or a set of second adjustment modules can be used to drive the two matching modules 24 at the same time. Figure 10-12As shown, during implementation, the second adjustment module may include a second adjustment power 231 and a second moving mechanism 232, the second adjustment power 231 is transmission-connected to the second moving mechanism 232, the second moving mechanism 232 is transmission-connected to the matching module 24, and the control module is connected to the second adjustment power 231. The second adjusting power 231 can adopt a stepping motor or a servo motor, etc. The second moving mechanism 232 is arranged along the second direction. The second moving mechanism 232 can adopt a belt transmission mechanism, a gear-rack 43 transmission mechanism or a screw-nut transmission mechanism, etc. In one embodiment, the two matching modules 24 can be connected to the support frame 21 through linear guides 25 respectively, so that the matching module 24 has the freedom to move along the second direction. At the same time, a set of second adjusting modules is configured for the two matching modules 24 respectively. The second moving mechanism 232 in the second adjusting module adopts a screw-nut transmission mechanism. The screw in the screw-nut transmission mechanism is rotatably installed on the support frame 21 and arranged along the second direction. The nut in the screw-nut transmission mechanism is threadedly connected to the screw and fixedly connected to the seat body 3 of the matching module 24. The second adjusting power 231 is connected to the screw transmission, and the matching module 24 is driven to move linearly along the second direction by driving the screw to rotate, thereby achieving the purpose of adjusting the distance between the two matching modules 24. It can be understood that the second adjustment module is also configured with a design to prevent the nut from rotating with the screw rod. This is a prior art and will not be explained one by one here.

[0063] In another preferred implementation manner provided in the present embodiment, the two matching modules 24 can be driven to move synchronously in the opposite direction along the second direction by the second adjusting power 231. This not only allows the distance W between the two matching modules 24 to be quickly adjusted to adapt to bag openings 11 of different widths, but also helps to simplify the control and folding process and improve the matching accuracy. In implementation, when the two matching modules 24 are respectively configured with a set of independent second adjusting modules, the two sets of second adjusting modules can be electrically connected to the control module respectively, so that the control module can be used to control the two second adjusting modules to move synchronously in the opposite direction. When the two matching modules 24 share a set of second adjusting modules, the second adjusting power 231 can be used to automatically control the two matching modules 24 to move synchronously in the opposite direction. At this time, as an example, Figure 10-12 As shown, the second adjustment module includes two second moving mechanisms 232, the two second moving mechanisms 232 are arranged in parallel along the second direction, the two second moving mechanisms 232 are arranged on both sides of the matching module 24, and the two ends of the two matching modules 24 in the second matching unit 23 are respectively connected to the two second moving mechanisms 232. Figure 10-11As shown, in this way, not only can the two second moving mechanisms 232 be used to support the two ends of the matching module 24 respectively, so that the two second moving mechanisms 232 can drive the two ends of the matching module 24 to move synchronously, ensuring that the matching module 24 moves strictly along the second direction, but also the second moving mechanisms 232 can drive the two matching modules 24 to move synchronously in the opposite direction along the second direction, thereby effectively improving the stability and reliability of the movement of the matching module 24. More specifically, as an example, in this embodiment, the two second moving mechanisms 232 are both belt transmission mechanisms, such as Fig.11 As shown, the belt transmission mechanism includes a driving pulley 54, a driven pulley 55 and a transmission belt 56. The two driving pulleys 54 are respectively connected to the transmission shaft 52. For example, Fig.11 As shown, two driving pulleys 54 can be symmetrically arranged at both ends of the transmission shaft 52, the transmission shaft 52 is connected to the carrier 21 through the bearing seat 53, and two driven pulleys 55 are rotatably installed on the carrier 21. The transmission belt 56 is tensioned on the driving pulley 54 and the driven pulley 55, and the two ends of one of the matching modules 24 are respectively connected to the upper sides of the two transmission belts 56. Fig.11 and Fig.13 As shown, the two ends of the other matching module 24 are respectively connected to the lower sides of the two transmission belts 56; the second adjustment power 231 can be directly connected to the transmission shaft 52, or can be connected to the transmission shaft 52 through a transmission structure 51 such as a belt transmission structure 51 or a gear transmission structure 51. When in use, the second adjustment power 231 drives the transmission shaft 52 to simultaneously connect the two belt transmission mechanisms, which can improve the synchronization of the two belt transmission mechanisms, thereby facilitating the synchronization of the two matching modules 24. At the same time, by connecting the two ends of one matching module 24 to the upper sides of the two transmission belts 56, and the two ends of the other matching module 24 to the lower sides of the two transmission belts 56, the two matching modules 24 can be driven by the second adjustment power 231 to move in the opposite direction synchronously, thereby improving efficiency and ensuring movement accuracy.

[0064] As an example, in the second matching unit 23, the pulling power 33 may preferably be a cylinder, such as Figure 10-12 As shown, one end of the cylinder can be connected to the seat body 3, and the other end is connected to the drawer 34. The cylinder is arranged along the second direction so that the cylinder can be extended and retracted along the second direction. The position of the drawer 34 along the second direction is adjusted by the extension and retraction of the cylinder. In order to improve the movement accuracy of the drawer 34 and make the structure more compact and smaller in size, the seat body 3 is configured with a guide groove 31 along the second direction, as shown in FIG. Fig.10As shown, the side of the pulling component 34 can be movably constrained in the guide groove 31 so that the guide groove 31 can be used to guide the pulling component 34. In addition, during implementation, the pulling power 33 can also be an electric push rod or a hydraulic cylinder, etc., which will not be explained one by one here. As an example, the upper pressing power 35 can also preferably use a cylinder, one end of the cylinder is connected to the seat body 3, and the other end is connected to the upper pressing component 36. The cylinder is retracted in the vertical direction so that the upper pressing component 36 can be driven to rise and fall in the vertical direction by the cylinder. When the upper pressing component 36 is at the lowest position at the bottom, it does not affect the folding action above; when the upper pressing component 36 rises, the bent bag edge piece 14 can be pressed against the pulling component 34 and / or the lower pressing mechanism 6. In order to ensure the strict vertical lifting of the upper pressing component 36, during implementation, it also includes a guide hole 32 constructed on the seat body 3 and a guide rod 37 adapted to the guide hole 32, such as Fig.10 and Fig.12 As shown, the guide rod 37 is vertically arranged, the lower end of the guide rod 37 is connected to the upper pressing part 36, and the upper end is connected to the movable end of the upper pressing power 35. The seat body 3 is sleeved on the guide rod 37 through the guide hole 32, so that the vertical movement of the upper pressing part 36 is guided by the cooperation between the guide rod 37 and the guide hole 32. In addition, during implementation, the pulling power 33 can also be an electric push rod or a hydraulic cylinder. In the second matching unit 23, the spacing between the two pulling parts 34 at the second position can be used as the spacing W of the two matching modules 24 along the second direction. Of course, the spacing between the two upper pressing parts 36 can also be used as the spacing W of the two matching modules 24 along the second direction.

[0065] It can be understood that in some other embodiments, the matching module 24 in the second matching unit 23 can be applied to the first matching unit 22, and similarly, the matching module 24 in the first matching unit 22 can be applied to the second matching unit 23, and examples are not given one by one here.

[0066] In actual use, the control module can automatically adjust the distance between the two matching modules 24 in the first matching unit 22 and the distance between the two matching modules 24 in the second matching unit 23 according to the size of the bag opening 11, so as to automatically adapt to the bag openings 11 of different sizes. Generally, the distance between the two matching modules 24 can be adjusted to be slightly larger than the size of the bag opening 11.

[0069] like Figure 16-Figure 17As shown, the frame 7 mainly plays a bearing role. The frame 7 is provided with a workbench 71 for bag opening. For the convenience of description, the length, width and height of the frame 7 are respectively referred to as the first direction (X direction), the second direction (Y direction) and the vertical direction (Z direction). Fig.16 shown.

[0070] The cutting module and the sewing module are connected to the frame 7 respectively. The cutting module can preferably adopt the existing laser cutting module, which is mainly used for processing the seams required for opening bags. The sewing module can also adopt the existing sewing module, which is mainly used for sewing.

[0071] During implementation, the folding device 8 can also adopt the existing folding device 8, and the folding device 8 can be lifted and lowered on the frame 7 through the linear guide rail 25. The side of the folding device 8 is provided with a folding structure 83, and the folding structure 83 includes a positioning surface 831 and a convex portion 832 protruding from the positioning surface 831. The convex portion 832 is configured with a limiting surface 833 for limiting the bag edge piece 14, so that the positioning surface 831 and the limiting surface 833 can form a hook shape, such as Fig.15 As shown, the folding structure 83 cooperates with the matching module 24 in the folding frame pressing device 2.

[0072] During implementation, the folding frame pressing device 2 can be configured to be movable relative to the frame 7 along the first direction, the second direction and the vertical direction, which makes it easier for the folding frame pressing device 2 to cooperate with the cutting module, the sewing module and the folding device 8. During implementation, the bag opening device also includes a first connecting frame 721, a second connecting frame 722, a first power 73, a second power 75 and a third power 77, wherein the first connecting frame 721 can be movably connected to the frame 7 through a linear guide 25, and forms a moving pair with the frame 7 along the first direction, and the first power 73 can be arranged on the frame 7 and be transmission-connected to the connecting frame for driving the connecting frame to move along the first direction. During implementation, the first power 73 can preferably adopt a stepper motor or a servo motor, and the first power 73 can preferably adopt a first transmission mechanism 74 such as a screw-nut transmission mechanism, a belt transmission mechanism and a gear-rack 43 transmission mechanism to be transmission-connected to the first connecting frame 721, such as Fig.16 As shown, the first connecting frame 721 is driven to move strictly along the first direction.

[0073] The second connecting frame 722 can be connected to the first connecting frame 721 through a linear guide rail 25 arranged in the vertical direction, and the second power 75 can be connected to the second connecting frame 722 through a second transmission mechanism 76 such as a screw-nut transmission mechanism, a belt transmission mechanism, and a gear-rack 43 transmission mechanism. Fig.16 As shown, the second connecting frame 722 is driven to move strictly in the vertical direction.

[0074] The carrier 21 can be connected to the second connecting frame 722 through a linear guide rail 25 arranged along the second direction, and the third power 77 can be connected to the carrier 21 through a third transmission mechanism 78 such as a screw-nut transmission mechanism, a belt transmission mechanism, and a gear-rack 43 transmission mechanism. Fig.16 As shown, the folding and pressing frame device 2 is driven to move strictly along the second direction, so that the folding and pressing frame device 2 has the freedom to move in three directions.

[0075] In implementation, the first power 73, the second power 75 and the third power 77 are connected to the control module respectively. The first power 73 can be a motor, the second power 75 can be a motor or a cylinder, and the third power 77 can be a motor.

[0076] When folding, the distance between the two matching modules 24 in the first matching unit 22 in the folding and pressing frame device 2 is adjusted according to the required length of the bag opening 11, so that the distance is adapted to the length of the bag opening 11; at the same time, the distance between the two matching modules 24 in the second matching unit 23 in the folding and pressing frame device 2 is adjusted according to the required length of the bag opening 11, so that the distance is adapted to the width of the bag opening 11.

[0077] Then the fabric 1 (or cloth) is laid flat on the folding frame pressing device 2, and the fabric 1 is pressed downward by the pressing mechanism 6 arranged on the folding frame pressing device 2. The pocket area 12 planned on the fabric 1 corresponds to the central insertion opening 26.

[0078] Then the folding frame pressing device 2 is moved to a position adapted to the laser cutting module, and the laser cutting module is used to cut a seam of a desired shape on the fabric 1.

[0079] Then the folding frame device 2 is moved to the position adapted to the folding device 8, and the folding is performed by the folding device 8 and the folding frame device 2. In this process, the folding device 8 is inserted into the folding frame device 2, so that the positioning surface 831 of the folding structure 83 corresponds to the fabric 1, and the limiting surface 833 is lower than the fabric 1, so that the bag edge piece 14 is bent, as shown in FIG. Fig.18 Then the pull member 34 on the corresponding side is started, and the pull member 34 is used to push the bag edge piece 14 against the positioning surface 831, as Fig.19 As shown, the fabric 1 is bent; then the folding device 8 is moved vertically, and the folded bag edge piece 14 is pressed by the limiting surface 833, as shown Fig. 20 Then drive the pull member 34 to move in the reverse direction to exit the folding structure 83, as shown Fig.21 Complete the hem on one side as shown.
