Description

Technical Field

[0001] This utility model relates to the field of bag opening machines, and in particular to a bag opening machine for secondary sewing of bags. Background Technology

[0002] In garment manufacturing, pocket opening machines are essential auxiliary processing machinery, mainly used to create pockets in specific locations on garments. The processing of the pocket opening requires cutting, folding, shaping, and sewing the pocket opening area. This involves creating a slit at the pocket opening, folding the cut pocket opening inwards to form a folded edge, shaping the pocket lip by placing it on the folded edge, and finally sewing.

[0003] Current bag opening positioning components are used to limit the bag opening and fold the cut edges of the bag opening. They combine the bag opening positioning mechanism and the folding mechanism into one device, resulting in an overly complex overall structure and high maintenance difficulty. Utility Model Content

[0004] To address the structural complexity and maintenance difficulties caused by integrating the bag opening positioning mechanism and the folding mechanism into the same device, this application provides a bag opening machine for secondary sewing and forming of pockets.

[0005] The pocket opening machine for secondary sewing and forming provided in this application adopts the following technical solution:

[0006] A pocket opening machine for secondary sewing includes a frame, a worktable, a main drive unit, a pocket opening material fixing assembly, a folding assembly, a pocket support assembly, a knife insertion assembly, a laser opening assembly, and a sewing assembly. The worktable is mounted on the frame, and the pocket support assembly, folding assembly, laser opening assembly, and sewing assembly are sequentially arranged on the worktable. The knife insertion assembly is located directly above the folding assembly. The main drive unit is mounted on the frame and is used to drive the pocket opening material fixing assembly to move back and forth between the pocket support assembly, folding assembly, laser opening assembly, and sewing assembly.

[0007] The laser bag opening component is used to laser cut the fabric; the bag opening positioning component is used to limit the bag opening and the auxiliary folding component controls the length and width of the bag opening; the folding component is used to fold the cut edge of the bag opening; the inserting knife component is used by the folding edge positioning component to fold the edge; and the sewing component is used to sew the bag lip or bag fabric piece onto the fabric.

[0008] By adopting the above technical solution, the bag opening material fixing component and the folding component are set separately. At the same time, the folding component is set directly below the inserting knife component. Since the bag opening material fixing component must pass under the inserting knife component, the folding component can be separated without affecting the operation steps, reducing the integration of the equipment and facilitating maintenance.

[0009] Preferably, the folding assembly includes a fourth driving member, a fifth driving member, a lifting plate, a pair of fixed material blocks, and a pair of pulling blades. The pulling blades have a feeding port for the long folded edge of the fabric to enter. The fourth driving member is located below the worktable and is used to drive the lifting plate to move vertically. The fifth driving member is located on the lifting plate and is used to drive the pair of fixed material blocks to move relative to each other along the width of the fabric. The pair of pulling blades are respectively located on the pair of fixed material blocks and are used to pull open the two long folded edges of the fabric. The worktable has a movable groove for the pair of fixed material blocks to move. The pair of pulling blades are always located above the worktable.

[0010] The device includes a base and a first seat. The first seat is provided with an open fixing plate, and a sewing groove is formed on the open fixing plate. A front push plate, a left push plate, a rear push plate, and a right push plate are arranged in sequence around the sewing groove. The front push plate, the left push plate, the rear push plate, and the right push plate form a material fixing window. The first seat is provided with a first drive assembly and a second drive assembly. The output end of the first drive assembly is provided with a first linkage mechanism. The first drive assembly drives the first linkage mechanism to control the front push plate and the rear push plate to move back and forth. The output end of the second drive assembly is provided with a second linkage mechanism. The second drive assembly drives the second linkage mechanism to control the left push plate and the right push plate to move left and right.

[0011] When the bag opening material fixing component moves between the folding component and the inserting component, the sewing groove is directly opposite the two material feeding ports.

[0012] By adopting the above technical solution, in the folding assembly, the fourth drive component controls the vertical movement of the lifting plate, which can flexibly adjust the height of the pulling knife and the fixing block according to factors such as fabric thickness, making it highly adaptable. The fifth drive component drives a pair of fixing blocks to move relative to each other along the width of the fabric, working with the pulling knife to pull open the two long folded edges of the fabric, preparing for subsequent processes. The pulling knife is always located above the worktable, facilitating fabric operation and positioning. In the sewing-related structure, the front push plate, left push plate, rear push plate, and right push plate form a fixing window. Drive assembly one and drive assembly two precisely control the movement of each push plate through the first and second linkage mechanisms, respectively, to achieve precise positioning of the bag openings of different sizes of fabric, facilitating subsequent sewing operations. When the bag opening fixing assembly moves between the folding assembly and the inserting knife assembly, the sewing groove is directly opposite the two inserting ports, ensuring a tight connection between the fabric folding, insertion, and sewing processes, improving production efficiency and product consistency, reducing manual intervention, and lowering the probability of errors.

[0013] Preferably, the drive assembly one includes a lead screw motor one, the first linkage mechanism includes a driven assembly, the front push plate is disposed at the output end of the lead screw motor one, the driven assembly is disposed between the rear push plate and the front push plate, and the driven assembly drives the rear push plate and the front push plate to approach or move away from each other.

[0014] By adopting the above technical solution, the lead screw motor, as the drive component, features high precision and accurate displacement control, enabling precise control of the front push plate's position. The driven component is positioned between the rear and front push plates. As the front push plate moves, the driven component stably drives the rear and front push plates to approach or move away from each other, ensuring the synchronicity and coordination of the front and rear push plate movements. This structural design allows for precise and reliable adjustment of the material positioning window's dimensions in the front-to-back direction, adapting to the positioning requirements of fabric bag openings of different sizes. This improves the accuracy of fabric positioning, thereby enhancing the quality and stability of the sewing process. It also reduces the probability of equipment failure due to drive instability, extending the equipment's service life.

[0015] Preferably, the bag support assembly includes a support, a first bag panel, a second bag panel, a first support component, and a second support component. The support is fixedly mounted on the workbench. A first lifting cylinder is provided on the support, which drives the first support component to move vertically. The first bag panel is mounted on the first support component and is used to receive the bag lip or bag fabric piece. A transverse cylinder is provided on the support, which drives the second support component to move horizontally. The second bag panel is mounted on the second support component and is used to receive the bag fabric piece.

[0016] When the first material collection panel is in the raised state, the first material collection panel and the second material collection panel are flush with the top surface of the worktable. When the first material collection panel is in the lowered state, the first material collection panel is located below the second material collection panel.

[0017] By adopting the above technical solution, the bag lip is placed on the first pocket panel. During the process of the bag opening machine's setting mechanism moving the bag lip away and sewing it with the garment bag opening, the bag fabric piece is placed on the second pocket panel. Then, the first pocket panel is lowered, and the second pocket panel moves to directly above the first pocket panel, so that the bag fabric piece completes the lateral movement in a suspended state relative to the worktable, and a second setting is performed, making the processing smoother and more automated.

[0018] Preferably, the first support assembly includes a first movable seat, a second movable seat, and a drive component. The first lifting cylinder drives the first movable seat to move in a vertical direction. The drive component is disposed on the first movable seat and is used to drive the second movable seat to move in a direction parallel to the movement direction of the second material-collecting panel. The first material-collecting panel is disposed on the second movable seat.

[0019] By adopting the above technical solution, the second movable seat can be moved by the driving component, and the horizontal position of the first material-holding panel can be adjusted to better match the different sizes of the bag lip.

[0020] Preferably, the inserting knife assembly includes a lifting platform, a second driving component, a third driving component, two movable frames, and a pair of long-side inserting knives. The second driving component is mounted on the frame and is used to drive the lifting platform to move vertically. The two movable frames are slidably connected to the lifting platform along the length of the fabric cut. The pair of long-side inserting knives are respectively fixed on the pair of movable frames. The third driving component is mounted on the lifting platform and is used to drive the movable frames to move relative to each other. The pair of long-side inserting knives are used to insert the long folded edge into the fabric cut.

[0021] By adopting the above technical solution, the second drive unit can precisely control the vertical movement of the lifting platform, thereby flexibly adjusting the height of the insert blade assembly to meet the needs of different fabric thicknesses and processing positions. Two movable frames can slide along the length of the fabric cut on the lifting platform, driven by the third drive unit to move relative to each other, thereby causing a pair of long-side insert blades fixed on them to move closer or further away, realizing the long-edge insertion operation for fabric cuts of different widths. This structural design has a clear division of labor, with each component working in concert, making the long-edge insertion into the fabric cut efficient and precise, effectively improving processing efficiency and product quality.

[0022] Preferably, the inserting knife assembly includes a lifting platform, a second driving component, a third driving component, two movable frames, and a pair of long-side inserting knives. The second driving component is mounted on the frame and is used to drive the lifting platform to move vertically. The two movable frames are slidably connected to the lifting platform along the length of the fabric cut. The pair of long-side inserting knives are respectively fixed on the pair of movable frames. The third driving component is mounted on the lifting platform and is used to drive the movable frames to move relative to each other. The pair of long-side inserting knives are used to insert the long folded edge into the fabric cut.

[0023] By adopting the above technical solution, the second drive unit can precisely control the vertical movement of the lifting platform, thereby flexibly adjusting the height of the insert blade assembly to meet the needs of different fabric thicknesses and processing positions. Two movable frames can slide along the length of the fabric cut on the lifting platform, driven by the third drive unit to move relative to each other, thereby causing a pair of long-side insert blades fixed on them to move closer or further away, realizing the long-edge insertion operation for fabric cuts of different widths. This structural design has a clear division of labor, with each component working in concert, making the long-edge insertion into the fabric cut efficient and precise, effectively improving processing efficiency and product quality.

[0024] Preferably, the inserter assembly includes a lifting platform, a horizontal adjustment platform, two XZ axis displacement drive platforms, a pair of long-side inserters, and a pair of short-side inserters;

[0025] The horizontal adjustment platform is mounted on the lifting platform and has a pair of horizontally adjustable movable platforms; the movable platforms are configured to drive the pair of movable platforms to move away from or towards each other.

[0026] The long-side insert includes a left insert and a right insert that can move relative to each other, and the left insert and the right insert are arranged one-to-one on two moving platforms;

[0027] Two XZ-axis displacement drive platforms are set one-to-one on two moving platforms; a pair of short-side inserts are set one-to-one on the XZ-axis displacement drive platforms so as to move along the XZ-axis direction driven by the XZ-axis displacement drive platforms.

[0028] By adopting the above technical solution, the horizontal adjustment platform can drive the two moving stages to move relative to each other along the X-axis. In conjunction with the XZ-axis displacement drive platform to drive the short side inserts in the XZ-axis direction, the length of the two long side inserts and the position of the two short side inserts can be flexibly adjusted to adapt to the requirements of different lengths of folding edges and pocket sizes. There is no need to frequently replace the inserts, which improves the applicability of the insert assembly. At the same time, this modular and adjustable structural design effectively reduces the complexity of operation and the cost of equipment maintenance.

[0029] Preferably, the XZ axis displacement drive platform includes a first cylinder, a first mounting frame, a second cylinder, and a second mounting frame. The first cylinder is fixedly mounted on the corresponding moving platform, and the piston rod of the first cylinder is fixedly mounted on the first mounting frame to drive the first mounting frame to move along the long side of the fabric cut. The second cylinder is fixedly mounted on the first mounting frame, and the piston rod of the second cylinder is vertically downward and fixed on the second mounting frame. The short-side insert is fixedly mounted on the second mounting frame.

[0030] By adopting the above technical solution, the drive assembly consisting of the first cylinder, the first mounting bracket, the second cylinder, and the second mounting bracket achieves precise displacement control of the short-side insert in the XZ axis direction; the first cylinder drives the first mounting bracket to move along the long side of the fabric cut, and the second cylinder drives the second mounting bracket and the short-side insert to rise and fall vertically, so that the short-side insert can accurately insert into the fabric fold and complete the edge-tightening action, ensuring the accuracy and stability of the folding process.

[0031] Preferably, the left insert and the right insert have the same structure, both including an integrally formed fixing part and a plug-in part. The fixing part is fixed to the corresponding moving platform by screws, and at least one side of its front or rear surface is flush with the surface of the fixing part. The fixing parts of the two long-side inserts are arranged on the same plane, and the plug-in parts are parallel and staggered to each other and are fitted together.

[0032] By adopting the above technical solution, no matter how the moving platform is adjusted, the two plug-in parts remain in a close-fitting plug-in state, and the connection between the two plug-in parts is stable, ensuring the consistency of the folded edge and the flatness of the pocket opening.

[0033] The main technical effects of this utility model are reflected in the following aspects:

[0034] 1. This utility model separates the bag opening material fixing component and the folding component, and places the folding component directly below the inserting knife component. Since the bag opening material fixing component must pass under the inserting knife component, the folding component can be separated without affecting the operation steps, reducing the integration of the equipment and facilitating maintenance.

[0035] 2. This utility model uses two driven methods to make the front push plate and the rear push plate, and the left push plate and the right push plate move relative to each other, so that the first lead screw motor and the second lead screw motor can be set on the same side, and the electrical components can be set in the same position to ensure more convenient circuit connection.

[0054] The following is in conjunction with the appendix Figures 1-17 This application will be described in further detail to make the technical solution of this application easier to understand and master.

[0055] This application discloses a pocket opening machine for secondary sewing and forming of pockets.

The worktable 1 is set on the frame 5, and the bag support assembly 2, the folding assembly 4, the laser bag opening assembly 7, and the sewing assembly 8 are arranged sequentially on the worktable 1. The knife insertion assembly is located directly above the folding assembly 4. The main drive unit 9 is set on the frame 5 and is used to drive the bag opening material fixing assembly to move back and forth between the bag support assembly 2, the folding assembly 4, the laser bag opening assembly 7, and the sewing assembly 8.

[0057] Reference Figure 1 and Figure 2 The laser opening component 7 is used to laser cut the fabric; the bag opening positioning component is used to limit the bag opening and the auxiliary folding component 4 controls the length and width of the bag opening; the folding component 4 is used to fold the cut edge of the bag opening; the inserting knife component is used to fold the edge of the folding component; and the sewing component 8 is used to sew the bag lip or bag fabric piece onto the fabric.

[0058] Reference Figure 1 and Figure 2 The laser bag opening assembly 7 includes a laser head 71, several laser tubes 72 and several reflectors 73. The several laser tubes 72 are fixedly mounted on the frame 5 along different length directions. The laser head 71 is fixedly mounted on the final output laser tube 72 along a fixed direction. The reflectors 73 are located between two adjacent laser tubes 72 and between the final output laser tube 72 and the laser head 71, and are used to reflect the laser.

[0059] Reference Figures 3-7 The bag opening material fixing assembly includes a base and a first base 31. An opening fixing plate 311 is provided on the first base 31. A sewing groove 312 is formed on the opening fixing plate 311. A front push plate 313, a left push plate 315, a rear push plate 314, and a right push plate 316 are arranged sequentially around the sewing groove 312. The front push plate 313, left push plate 315, rear push plate 314, and right push plate 316 form a material fixing window 318. A drive assembly 32 and a drive... The output end of the second drive assembly 33 is provided with a first linkage mechanism 34. The first drive assembly 32 drives the first linkage mechanism 34 to control the movement of the front push plate 313 and the rear push plate 314, and controls the width of the fixed material window 318. The output end of the second drive assembly 33 is provided with a second linkage mechanism 35. The second drive assembly 33 drives the second linkage mechanism 35 to control the movement of the left push plate 315 and the right push plate 316, and controls the length of the fixed material window 318.

[0060] Reference Figures 3-7The first linkage mechanism 34 connects the drive assembly 32 to the front push plate 313 and the rear push plate 314, and the second linkage mechanism 35 connects the drive assembly 33 to the left push plate 315 and the right push plate 316. This allows the two drive sources to drive the front push plate 313 and the rear push plate 314, the left push plate 315 and the right push plate 316 to move respectively. This reduces the number of drive sources required, reduces the space needed to install the drive sources, makes the equipment structure more compact, and reduces the production cost of the equipment.

[0061] Reference Figures 3-7 The drive assembly 32 includes a lead screw motor 321, which includes a motor, a lead screw with a motor output end, and a slider. The first linkage mechanism 34 includes a driven assembly 341. The front push plate 313 is fixed to the slider at the output end of the lead screw motor 321. The driven assembly 341 is disposed between the rear push plate 314 and the front push plate 313. The driven assembly 341 drives the rear push plate 314 and the front push plate 313 to approach or move away from each other.

[0062] Reference Figures 3-7 The driven assembly 341 includes a driven frame 342 and a hinge block 343. The driven frame 342 is slidably mounted on the first seat 31 via a slide rail structure. The hinge block 343 is rotatably mounted on the first seat 31. A connecting plate 344 and a connecting plate 345 are also provided between the push plate 313 and the lead screw motor 321. The connecting plate 344 is fixed to the output end of the lead screw motor 321, and the connecting plate 345 is fixedly mounted between the connecting plate 344 and the push plate 313. One end of the hinge block 343 is hinged to the driven frame 342. One end is hinged to the side end of the connecting plate 345. Both the driven frame 342 and the connecting plate 345 have U-shaped openings 346. Both ends of the hinge block 343 are provided with round-headed sliders 347, which rotate and slide in cooperation with the two U-shaped openings 346. The movement of the front push plate 313 drives the hinge block 343 to rotate, which in turn pushes the driven frame 342 to move. This causes the driven frame 342 to move closer to or further away from the front push plate 313, achieving the purpose of one driving source simultaneously driving the front push plate 313 and the rear push plate 314 to move.

[0063] Reference Figures 3-7The second drive assembly 33 includes a second lead screw motor 331, which has the same structure as the first lead screw motor 321. The second linkage mechanism 35 includes a first rocker arm 351, a second rocker arm 352, and a power push plate 353. A left push plate 315 and a right push plate 316 are respectively disposed at the tail ends of the first rocker arm 351 and the second rocker arm 352. The heads of the first rocker arm 351 and the second rocker arm 352 are respectively fixed to the two sides of the power push plate 353. The power push plate 353 is disposed at the output end of the second lead screw motor 331. When the power push plate 353 is moved by the drive motor 331, the first rocker arm 351 and the second rocker arm 352 drive the left push plate 315 and the right push plate 316 to move closer or further apart. Through the cooperation between the power push plate 353 and the first rocker arm 351 and the second rocker arm 352, the second lead screw motor 331 drives the left push plate 315 and the right push plate 316 to move respectively when the power push plate 353 is moved, so as to achieve the purpose of one drive source driving the left push plate 315 and the right push plate 316 to move at the same time.

[0064] Reference Figures 3-7 The first swing arm 351 and the second swing arm 352 have the same structure and are symmetrically arranged. Both the first swing arm 351 and the second swing arm 352 are hinged to the first seat 31. Both ends of the power push plate 353 are provided with elongated slots 354. The heads of the first swing arm 351 and the second swing arm 352 are provided with sliding rods 355, which slide within the elongated slots 354. The tails of the first swing arm 351 and the second swing arm 352 are provided with elongated slots 356. The tails of the left push plate 315 and the right push plate 316 are provided with sliding rods 357, which slide within the elongated slots 356. Inside 356, when the second lead screw motor 331 drives the power push plate 353 to move, the power push plate 353 drives the first swing rod 351 and the second swing rod 352 to swing around the hinge point and drive the left push plate 315 and the right push plate 316 to move. The first swing rod 351 and the second swing rod 352 are hinged on the first seat 31, and through the cooperation of the first slide rod 355 and the first long waist hole 354, when the power push plate 353 moves in the Y-axis direction, the first swing rod 351 and the second swing rod 352 swing, thereby driving the left push plate 315 and the right push plate 316 to move in the X-axis direction.

[0065] Reference Figures 3-7 By using two driven methods, the front push plate 313 and the rear push plate 314, and the left push plate 315 and the right push plate 316 can move relative to each other, so that the first lead screw motor 321 and the second lead screw motor 331 can be set on the same side, and the electrical components can be set in the same position to ensure more convenient circuit connection. Two lead screw motors are used when bending materials.

[0066] Reference Figures 3-7It also includes a first seat 31, a second seat 36, a third seat 37, a first pressure plate 371, and a second pressure plate 372. The first seat 31 is slidably connected to the base in the vertical direction. The first seat 31 is provided with a first driving member 317 for driving the first seat 31 to slide.

[0070] Reference Figures 3-7 The first pressure plate 371 can initially limit the fabric. Since there are only two long folds after laser cutting, the fabric without folds in the length direction has no additional limit and is prone to displacement and deformation. The second pressure plate 372 can press the two ends of the fabric in the length direction in the working area, so that the fabric is not easy to shift and deform during sewing, which can improve the flatness of the sewn fabric.

[0071] Reference Figures 3-7, the second pressing plate 372 is arranged in a "C" shape, and the second pressing plate 372 presses one end in the width direction and both ends in the length direction of the fabric in the working area. The "C"-shaped second pressing plate 372 has good stability and can also re-limit one of the folded edges in the width direction.

[0072] Referring to Figure 1 and Figure 8 , the total driving member 9 includes a first unit 91, a second unit 92 and two driving sources.

The fourth driving member 41 is arranged below the workbench surface 1, and the fourth driving member 41 is used to drive the lifting plate 43 to move in the vertical direction. The fifth driving member 42 is arranged on the lifting plate 43 and is used to drive a pair of material positioning blocks 44 to move relatively in the width direction of the fabric. A pair of material pulling knives 45 are respectively arranged on a pair of material positioning blocks 44, and a pair of material pulling knives 45 are respectively used to open the two long folded edges of the fabric. An activity groove 46 for the pair of material positioning blocks 44 to move is formed on the workbench surface 1, and a pair of material pulling knives 45 are always located above the workbench surface 1.

[0074] Referring to Figure 1 and Figure 9 , when the bag mouth material positioning component moves between the folding component 4 and the inserting knife component, the sewing groove 312 is aligned with the two material feeding ports 451.

[0076] Referring to Figure 1 and Figure 9The fifth driving component 42 includes a lead screw motor 3. The difference between lead screw motor 3 and lead screw motor 1 321 and lead screw motor 2 331 is that the lead screw is a reciprocating lead screw, there are two sliders 672, the two sliders 672 are threaded to the two ends of the reciprocating lead screw respectively, the two sliders 672 are slidably connected to the lifting plate 43, and a pair of fixed blocks 44 are fixed on the two sliders 672 respectively.

[0077] Reference Figure 1 , Figures 10-13 The inserter assembly includes a lifting platform 61, a horizontal adjustment platform, two XZ axis displacement drive platforms, a pair of long-side inserters 641 and a pair of short-side inserters 66.

[0078] Reference Figure 1 , Figures 10-13 The horizontal adjustment platform is mounted on the lifting platform 61 and has a pair of horizontally adjustable moving platforms 63; the moving platforms 63 are configured to drive the pair of moving platforms 63 to move away from or towards each other.

[0079] Reference Figure 1 , Figures 10-13 The long-side insert knife 641 includes a left insert knife 643 and a right insert knife 644 that can move relative to each other from left to right. The left insert knife 643 and the right insert knife 644 are arranged one-to-one on two moving platforms 63.

[0080] Reference Figure 1 , Figures 10-13 Two XZ axis displacement drive platforms are set one-to-one on two moving stages 63; a pair of short-side inserters 66 are set one-to-one on the XZ axis displacement drive platforms so as to move along the XZ axis direction driven by the XZ axis displacement drive platforms.

[0081] Reference Figure 1 , Figures 10-13 The X-axis direction is the direction of the long side of the fabric cut, and the Z-axis direction is the vertical direction.

[0082] Reference Figure 1 , Figures 10-13 The horizontal adjustment platform can drive two moving stages 63 to move relative to each other along the X-axis. In conjunction with the XZ-axis displacement drive platform to drive the short side inserter 66 in the XZ-axis direction, the length of the two long side inserters 641 and the position of the two short side inserters 66 can be flexibly adjusted to adapt to different lengths of folding edges and pocket size requirements. This eliminates the need for frequent inserter replacements and improves the applicability of the inserter assembly. At the same time, this modular and adjustable structural design effectively reduces the complexity of operation and equipment maintenance costs.

[0083] Reference Figure 1 , Figures 10-13The XZ axis displacement drive platform includes a first cylinder 662, a first mounting bracket 663, a second cylinder 664, and a second mounting bracket 665. The first cylinder 662 is fixedly mounted on the corresponding moving platform 63, and the piston rod of the first cylinder 662 is fixedly mounted on the first mounting bracket 663 to drive the first mounting bracket 663 to move along the long side of the fabric cut. The second cylinder 664 is fixedly mounted on the first mounting bracket 663, and the piston rod of the second cylinder 664 is vertically downward and fixed on the second mounting bracket 665. The short-side insert knife 66 is fixedly mounted on the second mounting bracket 665.

[0084] Reference Figure 1 , Figures 10-13 The drive assembly, consisting of the first cylinder 662, the first mounting bracket 663, the second cylinder 664, and the second mounting bracket 665, enables precise displacement control of the short-side insert 66 in the XZ axis direction. The first cylinder 662 drives the first mounting bracket 663 to move along the long side of the fabric cut, while the second cylinder 664 drives the second mounting bracket 665 and the short-side insert 66 to rise and fall vertically, so that the short-side insert 66 can accurately insert into the fabric fold and complete the edge-tightening action, ensuring the accuracy and stability of the folding process.

[0085] Reference Figure 1 , Figures 10-13 The first cylinder 662 is located on the back of the moving platform 63, and the second cylinder 664 is located on the front side of the moving platform 63. Both the first mounting bracket 663 and the second mounting bracket 665 are bent.

[0086] Reference Figure 1 , Figures 10-13 While ensuring the normal driving function of the short-side inserter 66, the spatial layout of the inserter assembly is effectively optimized to avoid interference between components, making the overall structure more compact and reasonable, and facilitating installation, debugging and daily maintenance.

[0087] Reference Figure 1 , Figures 10-13 The piston rods of the two first cylinders 662 are positioned directly opposite each other. Since there is a gap between the two moving platforms 63, the piston rods of the first cylinders 662 extend to one side of the gap between the two moving platforms 63, which can further optimize the spatial layout of the insert assembly.

[0088] Reference Figure 1 , Figures 10-13 The bottom end of the short side insert 66 is bent toward the side away from the long side insert 641 to form the tucked edge 661. This structural design can better guide the fabric into the tucked opening 451 of the hem plate when inserting the fabric hem, preventing the fabric from shifting or getting stuck, while enhancing the fixing effect of the fabric hem, making the hem operation smoother, and improving the quality of garment pocket production.

[0089] Reference Figure 1 , Figures 10-13 The left inserter 643 and the right inserter 644 have the same structure, both including an integrally formed fixing part 651 and a plugging part 652. The fixing part 651 is fixed to the corresponding moving stage 63 by screws. At least one of its front or rear surfaces is flush with the surface of the fixing part 651. The fixing parts 651 of the two long-side inserters 641 are arranged coplanarly, and the plugging parts 652 are parallel and staggered to each other and are fitted together.

[0090] Reference Figure 1 , Figures 10-13 Regardless of how the moving platform 63 is adjusted, the two plug-in parts 652 remain in a close-fitting plug-in state, and the connection between the two plug-in parts 652 is stable, ensuring the consistency of the folded edge and the flatness of the pocket opening.

[0091] Reference Figure 1 , Figures 10-13 The horizontal adjustment platform also includes a first motor 621, a bidirectional lead screw 622, and two drive frames 623. The first motor 621 is fixedly mounted on the lifting platform 61, and its output shaft is coaxially fixed to the bidirectional lead screw 622. The two drive frames 623 are respectively fixed to two movable platforms 63 by screws. The two ends of the bidirectional lead screw 622 are threadedly connected to the two drive frames 623. The two movable platforms 63 are located below the lifting platform 61, and the lifting platform 61 has two through-holes 611 for the two drive frames 623 to move. This allows for precise adjustment of the distance between the two movable platforms 63 to accommodate the hemming requirements of fabrics of different sizes.

[0092] Reference Figure 1 , Figures 10-13 A support block 612 is provided on the lifting platform 61. The other end of the bidirectional lead screw 622, which is away from the first motor 621, is rotatably connected to the support block 612. A cover 68 is fixed on the lifting platform 61 by screws, and the cover 68 covers the bidirectional lead screw 622 and part of the drive frame 623.

[0094] Reference Figure 1 , Figures 10-13 The cooperation between the slide rail 671 and the slider 672 makes the sliding between the moving platform 63 and the lifting platform 61, and between the first mounting bracket 663 and the moving platform 63 more stable and smooth, reduces the frictional resistance during the movement, improves the movement accuracy and response speed of the inserting knife assembly, enhances the durability of the structure, reduces mechanical wear, and extends the service life of the equipment.

[0095] Reference Figure 1 , Figures 10-13 The overall operation of the inserting knife assembly is as follows: Based on the length of the opening, the positions of the two moving platforms 63 are adjusted via a horizontal adjustment platform, causing the left and right inserting knives 643 and 644 of the long-side inserting knife 641 to take their positions. Then, when the fabric after the bag opening is cut moves directly below the inserting knife assembly, the lifting platform 61 moves down, and the pair of long-side inserting knives 641 insert the two long sides into the feeding ports 451 of the two pulling knives 45 respectively. Then, the piston rod of the second cylinder 664 extends downward, driving the two short-side inserting knives 66 to push the two short sides downward. Then, the piston rod of the first cylinder 662 extends, directly inserting the two short sides horizontally between the corresponding left push plate 315, right push plate 316, and opening fixing plate 311. The movement of the left push plate 315 and right push plate 316 causes the short sides of the fabric to move.

[0096] Reference Figure 2 , Figures 14-17 The bag support assembly 2 includes a support 21, a first bag panel 23, a second bag panel 25, a first support assembly, and a second support assembly. The support 21 is fixedly mounted on the workbench 1. A first lifting cylinder 22 is provided on the support 21, which drives the first support assembly to move vertically.

When the first material-collecting panel 23 is in the lowered state, the first material-collecting panel 23 is located below the second material-collecting panel 25.

[0098] Reference Figures 14-17 The bag lip is placed on the first pocket panel 23. During the process of the bag opening machine's fixing mechanism moving the bag lip away and sewing it with the garment bag opening, the bag fabric piece is placed on the first pocket panel 23. Then the first pocket panel 23 is lowered, and the second pocket panel 25 is moved to the original position of the first pocket panel 23. The fixing mechanism can move along the second pocket panel 25 to directly above the first pocket panel 23. Then the second pocket panel 25 is pulled away, and the first pocket panel 23 is moved up, so that the bag fabric piece, the bag lip, and the fabric are stacked. Then the fixing mechanism moves the bag fabric piece away for sewing. Throughout the process, the second pocket panel 25 moves smoothly, which can improve the stacking stability of the fabric, the bag fabric piece, and the bag lip.
