Description

Technical Field

[0001] This application relates to the field of garment processing technology, and in particular to a synchronous folding mechanism for a garment opening machine. Background Technology

[0002] In garment manufacturing, pocket opening machines are essential auxiliary processing machinery, mainly used to create pockets in specific locations on garments for carrying small items such as mobile phones and wallets. The conventional approach is to process the pocket opening and lip separately first, then sew the lip onto the opening to complete the pocket opening. The processing of the pocket opening involves cutting, folding, positioning and shaping the lip, and sewing. Folding involves turning the cut pocket opening inwards to form a folded edge.

[0003] The current bag folding mechanism is equipped with a folding blade. The folding blade can also be driven to move up or down through the lifting and traversing components to fold the bag opening downwards. However, each blade on each side needs to be controlled separately, resulting in a complex structure with poor linkage and weak coordination. Utility Model Content

[0004] This application provides a synchronous bag folding mechanism for a garment bag opening machine, which has a simple structure and good linkage and coordination.

[0005] To achieve the above objectives, the main technical solutions adopted in this application include:

[0006] This application provides a synchronous bag-folding mechanism for a garment bag-opening machine, including a folding frame, a bag-folding device, a servo motor, a front insert knife, and a rear insert knife. The servo motor is disposed on the folding frame, and its drive end is connected to the bag-folding device to drive the bag-folding device to move in the vertical direction. The front insert knife and the rear insert knife are both disposed on the bag-folding device to move synchronously up and down under the drive of the bag-folding device. The front insert knife is disposed in front of the rear insert knife and spaced apart from the rear insert knife. In the front-back direction, both the front insert knife and the rear insert knife are movable relative to the bag-folding device so that the front insert knife and the rear insert knife move closer to or further away from each other.

[0007] The synchronous bag-folding mechanism proposed in this application uses a servo motor to drive the bag-folding device to rise or fall, improving the motion accuracy of the front and rear insert blades and achieving synchronous consistency in their movements. This enhances the linkage and coordination between the front and rear insert blades during the bag-folding process. The movement of the front and rear insert blades closer to or further away from each other allows for adjustment of the distance between them, improving the flexibility and applicability of the synchronous bag-folding mechanism.

[0008] Optionally, the bag folding device includes a bag folding frame, a front slider, and a rear slider. The bag folding frame is connected to the drive end of the servo motor. Along the front-rear direction, both the front slider and the rear slider are slidably disposed on the bag folding frame. The front insert knife is fixed to the front slider, and the rear insert knife is fixed to the rear slider.

[0009] In the above scheme, the front slider guides the movement of the front insert knife, and the rear slider guides the movement of the rear insert knife, enabling precise adjustment of the front and rear insert knives.

[0010] Optionally, the bag folding device further includes a bag folding assembly, which is disposed on the bag folding frame and is used to control the front insert knife and the rear insert knife to move synchronously in the front-back direction.

[0011] In the above solution, one end of the folding bag assembly is connected to the front insert knife and the other end is connected to the rear insert knife. The folding bag assembly controls the front insert knife and the rear insert knife to move synchronously in the front and rear directions, thereby improving the synchronous displacement accuracy of the front insert knife and the rear insert knife.

[0012] Optionally, the front inserter includes a front inserter holder and a front inserter blade, the front inserter holder is fixed to the front slider, and the front inserter blade is detachably disposed on the front inserter holder; the rear inserter includes a rear inserter holder and a rear inserter blade, the rear inserter holder is fixed to the rear slider, and the rear inserter blade is detachably disposed on the rear inserter holder.

[0013] In the above solution, the front insert blade is detachably connected to the front insert tool holder, and the rear insert blade is detachably connected to the rear insert tool holder. When the front insert blade and the rear insert blade need to be replaced, only the front insert blade and the rear insert blade need to be removed for replacement. There is no need to remove the front insert tool holder and the rear insert tool holder, which simplifies the operation and reduces costs.

[0014] Optionally, the synchronous bag folding mechanism further includes a folding assembly, a left insert knife, and a right insert knife. The folding assembly includes a folding cylinder, which is disposed on the bag folding device. The output end of the folding cylinder is connected to the left insert knife and the right insert knife to drive the left insert knife and the right insert knife to move synchronously in the vertical direction.

[0015] In the above scheme, the output end of the folding cylinder is connected to the left and right inserting knives respectively, so that the folding cylinder can drive the left and right inserting knives to rise or fall simultaneously, which improves the linkage and coordination between the left and right inserting knives in the bag folding process. The bag folding process is smooth and fluid, which greatly improves the accuracy of bag folding and improves work efficiency.

[0016] Optionally, the folding assembly further includes a lifting plate, which is slidably fitted to the bag folding device along the vertical direction. The output end of the folding cylinder is connected to the lifting plate, and both the left insert and the right insert are disposed on the lifting plate.

[0017] In the above scheme, the lifting plate is connected to the left and right inserting knives. When the folding cylinder drives the lifting plate to move up and down, the lifting plate drives the left and right inserting knives to move simultaneously, thereby improving the linkage between the left and right inserting knives and improving the working accuracy of the left and right inserting knives.

[0018] Optionally, the folding assembly further includes a left connecting plate and a right connecting plate, which are respectively disposed at the left and right ends of the lifting plate and both extend downward; the left insert is disposed on the left connecting plate and the right insert is disposed on the right connecting plate, and both the left and right connecting plates are slidably engaged with the bag folding device via lifting sliders.

[0021] In the above scheme, the left cylinder drives the left insert knife to move left and right to achieve the bag folding operation. When the left cylinder drives the left insert knife to move in the left and right direction, the left slider provides guidance for the movement of the left insert knife, thereby improving the movement accuracy of the left insert knife.

[0023] In the above scheme, the right cylinder drives the right insert knife to move left and right to achieve the bag folding operation. When the right cylinder drives the right insert knife to move in the left and right direction, the right slider provides guidance for the movement of the right insert knife, thereby improving the movement accuracy of the right insert knife.

[0024] Optionally, the left connecting plate includes a left connecting plate body and a left mounting plate. In the left-right direction, the left mounting plate is disposed on the side of the left connecting plate body away from the right connecting plate, and the left mounting plate is provided with a left slide rail that slides with the left slider.

In the left-right direction, the right mounting plate is disposed on the side of the right connecting plate body away from the left connecting plate, and the right mounting plate is provided with a right slide rail that slides with the right slider.

[0025] In the above scheme, the left connecting plate body is connected to the bag folding device via a lifting slider. The left mounting plate is located on the side of the left connecting plate body away from the right connecting plate. The left connecting plate body moves up and down in the vertical direction, thereby realizing the adjustment of the left insert knife in the left-right and up-down directions and improving the accuracy of the left insert knife's movement. The right connecting plate body is connected to the bag folding device via a lifting slider. The right mounting plate is located on the side of the right connecting plate body away from the left connecting plate. The right insert knife moves in the left-right direction, and the right connecting plate body moves up and down in the vertical direction, thereby realizing the adjustment of the right insert knife in the left-right and up-down directions and improving the accuracy of the right insert knife's movement.

[0026] Optionally, the drive end of the servo motor is provided with a lifting gear, and the folding device is provided with a lifting rack that meshes with the lifting gear.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0044] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0045] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0046] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0047] In this application, "multiple" refers to two or more (including two), and similarly, "multiple groups" refers to two or more (including two), and "multiple pieces" refers to two or more (including two).

[0048] Current bag folding mechanisms include fabric folding blades, which can be driven to move up and down or laterally via lifting and traversing components to fold the bag opening downwards. However, each blade requires a separate motor or cylinder for individual control, resulting in a complex structure. Furthermore, the poor linkage and coordination between the blades on opposite sides can lead to skewing and asymmetry during the folding process. Therefore, this application provides a simple, synchronized bag folding mechanism with better linkage and coordination.

[0049] refer to Figure 1 and Figure 2This application provides a synchronous folding mechanism for a garment bag opening machine. The synchronous folding mechanism includes a folding frame 1, a folding device 2, a servo motor 3, a front inserting knife 4, and a rear inserting knife 5. The servo motor 3 is mounted on the folding frame 1, and its drive end is connected to the folding device 2 to drive the folding device 2 to move in the vertical direction A. The front inserting knife 4 and the rear inserting knife 5 are both mounted on the folding device 2 to move synchronously up and down under the drive of the folding device 2. The front inserting knife 4 is located in front of the rear inserting knife 5 and is spaced apart from the rear inserting knife 5. In the front-back direction B, the front inserting knife 4 and the rear inserting knife 5 are movable relative to the folding device 2 so that the front inserting knife 4 and the rear inserting knife 5 move closer to or further away from each other.

[0050] The servo motor 3 has high motion precision. One end of the servo motor 3 is fixed to the folding frame 1, which provides support for the servo motor 3. The drive end of the servo motor 3 is connected to the folding device 2 to drive the folding device 2 to rise or fall.

[0051] The overall lifting and lowering of the folding device 2 is precisely controlled by the servo motor 3. The front insert knife 4 and the rear insert knife 5 are both set on the folding device 2. When the servo motor 3 drives the folding device 2 to rise or fall, the front insert knife 4 and the rear insert knife 5 rise or fall simultaneously with the folding device 2. This ensures that the front insert knife 4 and the rear insert knife 5 are at the same height when inserting the fabric and pressing the pocket folding edge, reducing problems such as skewed or asymmetrical folding edges caused by the asynchronous movement of the front insert knife 4 and the rear insert knife 5.

[0052] Furthermore, both the front insert knife 4 and the rear insert knife 5 can move relative to the bag-opening device. That is, the front insert knife 4 and the rear insert knife 5 can move closer to or further away from each other to adjust the distance between them. This adjustment can be made for different sizes and styles of pockets. The front insert knife 4 and the rear insert knife 5 can be connected to the bag-opening device 2 via a lead screw, a rack and pinion mechanism, or a sliding rail and slider to achieve relative movement between them. Of course, other suitable connection methods are also possible, and this application is not limited to these.

[0053] The synchronous bag-folding mechanism proposed in this application uses a servo motor 3 to drive the bag-folding device 2 to rise or fall, improving the motion accuracy of the front insert blade 4 and the rear insert blade 5, and simultaneously achieving consistency in the movements of the front insert blade 4 and the rear insert blade 5, thus enhancing the linkage and coordination between the front insert blade 4 and the rear insert blade 5 during the bag-folding process. The movement of the front insert blade 4 and the rear insert blade 5 towards or away from each other allows for adjustment of the distance between the front insert blade 4 and the rear insert blade 5, improving the flexibility and applicability of the synchronous bag-folding mechanism.

[0054] It should be noted that, since a servo motor 3 with high lifting accuracy is used to drive the bag folding device 2 to rise or fall, there is no need to use the existing two cylinders (coarse adjustment cylinder and fine adjustment cylinder) for adjustment, thereby reducing the manufacturing cost of the bag folding mechanism and making the overall structure of the bag folding mechanism simpler.

[0055] Optionally, the synchronous bag folding mechanism also includes a lifting gear and a lifting rack. The lifting gear is located at the drive end of the servo motor 3, and the lifting rack is located on the bag folding device 2 in the up-down direction A. The lifting rack meshes with the lifting gear. When the servo motor 3 rotates, it drives the lifting gear to rotate, thereby driving the lifting rack to rise or fall, and thus driving the bag folding device 2 to rise or fall precisely.

[0056] Optionally, refer to Figure 2 The bag folding device 2 includes a bag folding frame 21, a front slider 22 and a rear slider 23. The bag folding frame 21 is connected to the drive end of the servo motor 3. Along the front-back direction B, both the front slider 22 and the rear slider 23 are slidably mounted on the bag folding frame 21. The front insert knife 4 is fixed to the front slider 22 and the rear insert knife 5 is fixed to the rear slider 23.

[0057] Specifically, the folding bag frame 21 is provided with a first guide rail, which is located along the front-to-back direction B. The front slider 22 and the rear slider 23 are slidably connected to the first guide rail. For example, along the left-to-right direction C, the folding bag frame 21 is provided with two first guide rails, which are spaced apart along the left-to-right direction C. The front insert knife 4 is connected to the two first guide rails through the front slider 22, which can improve the movement stability of the front insert knife 4. The rear insert knife 5 is connected to the two first guide rails through the rear slider 23, which can improve the movement stability of the rear insert knife 5.

[0058] The front slider 22 guides the movement of the front insert knife 4, and the rear slider 23 guides the movement of the rear insert knife 5, enabling precise adjustment of the front insert knife 4 and the rear insert knife 5. Furthermore, the distance between the front insert knife 4 and the rear insert knife 5 can be freely adjusted along the front-back direction B. Operators can quickly adjust the front-back distance between the two insert knives according to the pocket size requirements, enhancing the equipment's adaptability to processing garment pockets of different specifications.

[0059] A cable tray 24 connects the folding rack 1 and the bag folding rack 21. The cable tray 24 collects various exhaust pipes to ensure the neatness of the equipment cable routing.

[0060] Optionally, refer to Figure 2 The bag folding device 2 also includes a bag folding assembly 25, which is disposed on the bag folding frame 21 and is used to control the front insert knife 4 and the rear insert knife 5 to move synchronously in the front-back direction B.

[0061] One end of the folding pocket assembly 25 is connected to the front insert knife 4, and the other end is connected to the rear insert knife 5. The folding pocket assembly 25 controls the front insert knife 4 and the rear insert knife 5 to move synchronously in the front-back direction B, which improves the synchronous displacement accuracy of the front insert knife 4 and the rear insert knife 5. At the same time, it can make the front insert knife 4 and the rear insert knife 5 highly consistent in the action of inserting the fabric and pressing the pocket folding edge, reducing problems such as skewed and asymmetrical folding edges caused by the asynchronous movement of the front insert knife 4 and the rear insert knife 5.

[0062] For example, the folding bag assembly 25 can be a two-way lead screw structure or a gear and rack structure.

[0063] In one specific embodiment, reference Figures 1 to 3 The folding bag assembly 25 includes a folding plate 251 connected to the folding bag frame 21, a folding cylinder 252 connected to the folding plate 251, and a folding component 253 fixed to the drive end of the folding cylinder 252. Side sliders 254 that cooperate with the folding frame 21 are provided on the left and right sides of the folding component 253, providing guidance for the up-and-down movement of the folding component 253. Hinges 255 are connected to the front insert 4 and the rear insert 5 on the front and rear sides of the lower end of the folding component 253, respectively. The front hinge block 255 is hinged to the front insert 4 on the front side of the folding component 253, and the rear hinge block 255 is hinged to the rear insert 5 on the rear side of the folding component 253. The folding cylinder 252 drives the folding component 253 to rise. When the folding component 253 rises, relative rotation occurs between the folding component 253 and the hinge block 255. The hinge block 255 pulls the front insert knife 4 and the rear insert knife 5 closer together. That is, the folding component 253, through the hinge block 255, drives the front insert knife 4 and the rear insert knife 5 to move closer to each other, reducing the distance between the front insert knife 4 and the rear insert knife 5. The folding cylinder 252 drives the folding component 253 to fall. When the folding component 253 falls, the distance between the folding component 253 and the hinge block 255 decreases. When relative rotation occurs, the hinge block 255 pushes the front insert knife 4 and the rear insert knife 5 away from each other. In other words, the folding bag component 253 drives the front insert knife 4 and the rear insert knife 5 to move away from each other through the hinge block 255, increasing the distance between the front insert knife 4 and the rear insert knife 5. This achieves the purpose of synchronous adjustment of the front insert knife 4 and the rear insert knife 5 by driving the hinge block 255 through the folding bag component 253, improving the linkage and coordination of the front insert knife 4 and the rear insert knife 5, and reducing the probability of folding skewing caused by uneven force on one side of the insert knife.

[0064] In other words, the rotation of the hinge block 255 can be used to synchronously convert the up-and-down movement of the folding component 253 into the horizontal sliding of the front insert blade 4 and the rear insert blade 5. This facilitates precise control of the front insert blade 4 and the rear insert blade 5 based on the cylinder stroke and speed, thereby achieving precise control of the sliding amount of the front insert blade 4 and the rear insert blade 5 and ensuring the synchronicity of the folding action. At the same time, the hinged connection between the front insert blade 4 and the rear insert blade 5 and the folding component 253 can buffer the impact during the movement, reduce vibration, and make the sliding process of the front insert blade 4 and the rear insert blade 5 smoother. This improves the accuracy of the synchronous movement of the front insert blade 4 and the rear insert blade 5, especially during high-speed operation, effectively reducing folding errors caused by movement impact and reducing the risk of fabric damage.

[0065] Optionally, refer to Figure 2 The front inserter 4 includes a front inserter holder 41 and a front inserter blade 42. The front inserter holder 41 is fixed to the front slider 22, and the front inserter blade 42 is detachably mounted on the front inserter holder 41. The rear inserter 5 includes a rear inserter holder 51 and a rear inserter blade 52. The rear inserter holder 51 is fixed to the rear slider 23, and the rear inserter blade 52 is detachably mounted on the rear inserter holder 51.

[0066] The front insert blade 42 can be connected to the front insert tool holder 41 by means of bolts or quick-release clips, and the rear insert blade 52 can be connected to the rear insert tool holder 51 by means of bolts or quick-release clips. When the front insert blade 42 and / or the rear insert blade 52 need to be replaced, it is only necessary to remove the front insert blade 42 and / or the rear insert blade 52 for replacement, without having to remove the front insert tool holder 41 and the rear insert tool holder 51. This simplifies the operation and reduces costs.

[0067] Optionally, refer to Figures 1 to 3 The synchronous bag folding mechanism also includes a folding component 6, a left insert knife 7, and a right insert knife 8. The folding component 6 includes a folding cylinder 61, which is located on the bag folding device 2. The output ends of the folding cylinder 61 are connected to the left insert knife 7 and the right insert knife 8 to drive the left insert knife 7 and the right insert knife 8 to move synchronously in the up-down direction A.

[0068] The folding cylinder 61 is installed on the bag folding device 2. When the servo motor 3 drives the bag folding device 2 to move up and down, the folding cylinder 61 moves up and down synchronously with the bag folding device 2. The output end of the folding cylinder 61 is connected to the left insert knife 7 and the right insert knife 8 respectively, so that the folding cylinder 61 can drive the left insert knife 7 and the right insert knife 8 to rise or fall simultaneously. This improves the linkage and coordination between the left insert knife 7 and the right insert knife 8 in the bag folding process, making the bag folding process smooth and efficient, greatly improving the accuracy of bag folding and increasing work efficiency.

[0069] The left and right insert blades can fold bags from the left and right directions, and can be used in conjunction with the front and rear insert blades to fold bags at multiple angles. With this design, for irregular bag openings (such as Y-shaped or trapezoidal bag openings), the left and right insert blades can move left and right to precisely fit the outline of the bag opening, filling the side areas that the front and rear insert blades cannot cover, reducing manual folding processes, reducing the number of folding steps, and helping to improve folding efficiency.

[0070] Optionally, refer to Figures 1 to 3 The folding assembly 6 also includes a lifting plate 62. Along the vertical direction A, the lifting plate 62 is slidably fitted to the folding bag device 2. The output end of the folding cylinder 61 is connected to the lifting plate 62. The left insert knife 7 and the right insert knife 8 are both set on the lifting plate 62.

[0071] The lifting plate 62 is connected to the left insert knife 7 and the right insert knife 8. When the folding cylinder 61 drives the lifting plate 62 to move up and down, the lifting plate 62 drives the left insert knife 7 and the right insert knife 8 to move simultaneously, thereby improving the linkage between the left insert knife 7 and the right insert knife 8 and improving the working accuracy of the left insert knife 7 and the right insert knife 8, reducing problems such as skewed or asymmetrical folding lines caused by the asynchronous movement of the left insert knife 7 and the right insert knife 8.

[0072] Optionally, refer to Figure 2 and Figure 3 The folding assembly 6 also includes a left connecting plate 63 and a right connecting plate 64, which are respectively located at the left and right ends of the lifting plate 62 and both extend downwards; a left insert 7 is located on the left connecting plate 63 and a right insert 8 is located on the right connecting plate 64, and both the left connecting plate 63 and the right connecting plate 64 are slidably engaged with the bag folding device 2 via the lifting slider 65.

[0073] The left connecting plate 63 is connected to the bag folding device 2 via a left-side lifting slider 65, which guides the sliding of the left connecting plate 63. The right connecting plate 64 is connected to the bag unpacking device via a right-side lifting slider 65, which guides the sliding of the right connecting plate 64. The bag folding frame 21 is equipped with a second slide rail, on which the lifting slider 65 is mounted. To improve the stability of the sliding of the left and right connecting plates 63 and 64, two second slide rails are provided on both the left and right sides of the bag folding frame 21. The left and right connecting plates 63 and 64 are equipped with lifting sliders 65 corresponding to the second slide rails. The left and right connecting plates 63 and 64 are respectively connected to the left and right sides of the lifting plate 62. When the folding cylinder 61 drives the lifting plate 62 to move up and down, the lifting plate 62 drives the left insert knife 7 and the right insert knife 8 to move up and down simultaneously along the bag folding device 2, improving the coordination of the synchronous bag folding mechanism.

[0074] For example, refer to Figure 2The bag folding frame 21 is provided with a lifting stroke groove 10. Both ends of the lifting plate 62 pass through the lifting stroke groove 10, and the lifting stroke groove 10 limits the lifting stroke of the folding component 6.

[0075] Optionally, refer to Figure 1 and Figure 2 The left connecting plate 63 is provided with a left slider 66 that slides in the left-right direction C.

The right side of the left connecting plate body 631 is connected to the folding bag device 2 through the lifting slider 65. The left mounting plate 632 is located on the side of the left connecting plate body 631 away from the right connecting plate 64. The left insert 7 is slidably connected to the left slide rail on the left mounting plate 632 through the left slider 66. The left insert 7 moves in the left-right direction C, and the left connecting plate body 631 moves up and down in the vertical direction, thereby realizing the adjustment of the left insert 7 in the left-right direction C and the up-down direction A, and improving the accuracy of the movement of the left insert 7. The upper part of the right connecting plate body 641 is connected to the lifting plate 62. The left side of the right connecting plate body 641 is connected to the folding bag device 2 through the lifting slider 65. The right mounting plate 642 is located on the side of the right connecting plate body 641 away from the left connecting plate 63.

The right slider 67 and the right slide rail provide guidance for the movement of the right insert knife 8. The right insert knife 8 moves in the left-right direction C, and the right connecting plate body 641 moves up and down in the vertical direction, thereby realizing the adjustment of the right insert knife 8 in the left-right direction C and the up-down direction A, and improving the accuracy of the movement of the right insert knife 8.

[0082] The left insert knife 7 includes a left insert knife holder 71 fixed on the left slider 66 and a left insert blade 72 detachably mounted on the left insert knife holder 71. The right insert knife 8 includes a right insert knife holder 81 fixed on the right slider 67 and a right insert blade 82 detachably mounted on the right insert knife holder 81. The detachable mounting facilitates the replacement of the insert blade and ensures the stability of the folded bag.

[0083] The left insert blade 72 can be connected to the left insert tool holder 71 by means of bolts or quick-release clips, and the right insert blade 82 can be connected to the right insert tool holder 81 by means of bolts or quick-release clips. When the left insert blade 72 and / or the right insert blade 82 need to be replaced, it is only necessary to remove the left insert blade 72 and / or the right insert blade 82 for replacement, without having to remove the left insert tool holder 71 and the right insert tool holder 81. The operation is simple and the cost is reduced.

[0084] In this application, both the front insert knife 4 and the rear insert knife 5 are disposed on the folding device 2. The front insert knife 4 is disposed in front of the rear insert knife 5 and spaced apart from it. Along the front-rear direction B, both the front insert knife 4 and the rear insert knife 5 are slidably engaged with the folding device 2. Simultaneously, the folding device 2 is equipped with a folding cylinder 252. The output end of the folding cylinder 252 is connected to the folding component 253. The front insert knife 4 is connected to the folding component 253 via a front hinge block 255, and the rear insert knife 5 is connected to the folding component 253 via a rear hinge block 255. Thus, while the folding cylinder 252 drives the folding component 253 to move up and down, the bag folding device 253 is folded. The bag component 253 can drive the front insert knife 4 and the rear insert knife 5 to move through the front hinge block 255 and the rear hinge block 255 respectively, thereby realizing the synchronous sliding of the front insert knife 4 and the rear insert knife 5 relative to the bag folding device 2. On the one hand, it can reduce the bag opening folding deviation caused by the asynchronous movement of the insert knife, and can make both sides of the fabric bag opening folded at the same time and evenly, so that the folded bag opening is more neat and standardized. On the other hand, since the front insert knife 4 and the rear insert knife 5 can work synchronously, there is no need to make additional adjustments and calibrations during the bag folding process, which greatly shortens the bag folding time and improves the bag folding efficiency.

[0085] When bag folding is required, servo motor 3 is activated, which drives bag folding frame 21 to descend. Bag folding frame 21 drives bag folding assembly 25, front insert knife 4, rear insert knife 5, folding assembly 6, left insert knife 7, and right insert knife 8 to descend to the predetermined position. Then, bag folding cylinder 252 drives bag folding component 253 to move downward under the guidance of side slider 254. As bag folding component 253 moves downward, it drives two hinge blocks 255 to rotate in opposite directions, thereby moving front insert knife 4 and rear insert knife 5 in opposite directions to the position where the bag fabric needs to be clamped. As front insert knife 4 and rear insert knife 5 move downward, they also move away from each other, increasing the distance between them. Then, front insert knife 4 and rear insert knife 5 clamp the folded edge of the fabric. Next, the folding cylinder 61 drives the lifting plate 62, which in turn moves the left connecting plate 63 and the right connecting plate 64 downwards under the guidance of the lifting slider 65. This causes the left insert knife 7 and the right insert knife 8 to move downwards synchronously to the position where the pocket fabric needs to be clamped. Then, the left cylinder 68 drives the left slider 66, which moves the left insert knife 7 away from the right connecting plate 64, and the right cylinder 69 drives the right slider 67, which moves the right insert knife 8 away from the left connecting plate 63. This allows the left insert knife 7 and the right insert knife 8 to clamp the folded edge of the fabric, thus enabling subsequent work. It should be understood that, depending on the pocket type, such as an "I" shaped opening, only the front insert knife 4 and the rear insert knife 5 can be used to clamp the folded edge of the fabric. If the pocket type is a "Y" shaped opening, the front insert knife 4 and the rear insert knife 5, as well as the left insert knife 7 and the right insert knife 8, can be used simultaneously.

[0086] After the pocket is sewn, the folding cylinder 252 drives the folding component 253 to move upward under the guidance of the side slider 254. As the folding component 253 moves upward, it drives the two hinge blocks 255 to rotate towards each other. The front insert knife 4 and the rear insert knife 5 move towards each other, and the front insert knife 4 and the rear insert knife 5 are retracted to their initial positions. Left cylinder 68 drives left slider 66 to move left insert knife 7 towards the right connecting plate 64. Right cylinder 69 drives right slider 67 to move right insert knife 8 towards the left connecting plate 63. Then, folding cylinder 61 drives lifting plate 62 to move left connecting plate 63 and right connecting plate 64 upward under the guidance of lifting slider 65, so that left insert knife 7 and right insert knife 8 move upward synchronously to the initial position for the next round of operation. Alternatively, servo motor 3 drives bag folding frame 21 to rise, and bag folding frame 21 drives bag folding assembly 25, front insert knife 4, rear insert knife 5, folding assembly 6, left insert knife 7 and right insert knife 8 to the initial position, thereby closing the synchronous bag folding mechanism.
