[0040] As described in the background, the current bag making equipment needs to manually adjust the related working parameters of each bag making component when dealing with different specifications of three-dimensional bags. For example, first manually adjust the mechanical handle, bolt and other related components, and adjust the position of each bag making component one by one. After adjustment, trial production is carried out and sample size is measured to verify the adjustment result. If the sample size does not meet the requirements, the position of the bag making component is adjusted again, and the above steps are repeated until the size of the three-dimensional bag meets the requirements. The adjustment process involves manually disassembling, moving and reinstalling each actuator and its driving components on the bag making equipment. The repeated disassembly and assembly not only accelerates the wear of the equipment connecting parts, but also greatly prolongs the machine adjustment time, which greatly affects the production efficiency.

[0041] Therefore, the present application provides a three-dimensional bag making equipment for automatically making three-dimensional bags with handles. This three-dimensional bag making equipment can conveniently adjust the initial position of the handle fixing device and the forming device when processing three-dimensional bags of different sizes, thereby adapting to the processing of three-dimensional bags of different sizes. The adjustment process takes less time, which can shorten the machine adjustment period and improve production efficiency.

[0042] In order to make the purpose, technical scheme and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0043] As Figure 1 and Figure 2As shown, the application provides a three-dimensional bag manufacturing device, which comprises a handle fixing station and a forming station arranged in sequence along a production line. The handle fixing station is provided with a handle fixing device 200 for fixing handles on both side edges of the base material along the width direction thereof. The forming station is provided with a forming device 300 for forming the base material into a three-dimensional bag. The handle fixing device 200 comprises a pair of handle fixing assemblies 210 arranged oppositely on a rack 100 along the width direction. The pair of handle fixing assemblies 210 respectively fix handles on both side edges of the base material along the width direction (see direction H) thereof, and at least one of the pair of handle fixing assemblies 210 is movably connected to the rack 100 along the width direction. The forming device 300 comprises a mold 310 which is liftable connected to the rack 100, and a pair of receiving platforms 320 which are located below the mold 310. A forming hole (see direction H) for the mold 310 to pass through is formed between the pair of receiving platforms 320, and at least one of the pair of receiving platforms 320 is movably connected to the rack 100 along the width direction. Figure 1 Figure 3 Figure 4 Figure 5

[0044] In practical applications, the base material can be understood as a piece of material which is pre-cut for forming a single bag body, or a continuous roll of material which is cut into a single piece before forming. The material can be non-woven fabric, paper, plastic or other materials.

[0045] When manufacturing the three-dimensional bag, the handles need to be fixed on both side edges of the base material first, and then the base material is formed into a three-dimensional bag by the forming device 300.

[0046] The handle fixing station and the forming station can be platforms located on the rack 100 respectively. The specific structure and arrangement of the handle fixing device 200 and the forming device 300 are introduced below.

[0047] The handle fixing device 200 can be understood as a mechanism for fixing handles on the base material, and the handle fixing on both side edge positions of the base material is achieved by the pair of handle fixing assemblies 210. Specifically, the handle fixing assembly 210 can move the two ends of the handle to the position on the base material for fixing the handle by a mechanical clamp or a suction cup structure, and then fix the end of the handle on the base material by using ironing or gluing.

[0048] ​​​​For example, for non-woven fabric, after the mechanical clamp or suction disc structure moves the two ends of the handle to the position on the base material for fixing the handle, the ultrasonic welding mechanism can be used to weld the two ends of the handle on the base material. For paper, the area of the base material where the handle is fixed can be pre-coated with glue, and after the mechanical clamp or suction disc structure moves the two ends of the handle to the position on the base material for fixing the handle, the pressing mechanism is used to press and bond the end of the handle on the base material.

[0049] Further, the design of at least one of the handle fixing assemblies 210 being movable in the width direction can be that the movement of one of the pair of handle fixing assemblies 210 adjusts the distance between the pair of handle fixing assemblies 210, or the synchronous movement of the pair of handle fixing assemblies 210 adjusts the distance between the pair of handle fixing assemblies 210.

[0050] It should be understood by those skilled in the art that when the movement of one of the pair of handle fixing assemblies 210 adjusts the distance between the pair of handle fixing assemblies 210, the conveying structure of the base material needs to be moved synchronously with the one handle fixing assembly 210, so that the base material is in a relatively central position between the pair of handle fixing assemblies 210, ensuring the accuracy of the handle fixing. For example, the conveying structure of the base material and the handle fixing assembly 210 that needs to be moved can be integrated, and the conveying structure of the base material and the handle fixing assembly 210 that needs to be moved are installed on the same moving structure, so as to realize the synchronous adjustment of the conveying structure and the handle fixing assembly 210.

[0051] The specific structure of the conveying structure in the present application is not limited, for example, various conveying structures such as conveying belt, moving suction disc, etc.

[0052] Regarding the moving structure of the handle fixing assembly 210, for example, the handle fixing assembly 210 can be moved in the width direction through linkage of slide rail, screw drive, linear motor drive or hydraulic cylinder drive, etc., so as to adapt to the requirement of base material of different widths. The specific structure is further explained in the following, which will not be repeated here.

[0053] Regarding the forming device 300, the forming device 300 can be understood as a mechanism for forming a sheet material into a three-dimensional bag, the sheet material being an independent base material unit after the base material is cut for making a single bag body; it can be through the cooperation of the mold 310 and the receiving platform 320 to complete the forming operation of the bag body. Specifically, the mold 310 is movably arranged above the receiving platform 320, and the receiving platform 320 is formed with a through hole for the mold 310 to pass through. When the mold 310 moves from top to bottom, the sheet material will be folded in half and attached to the mold 310 due to the interaction of the stamping of the mold 310 and the through hole. At this time, the two front walls of the three-dimensional bag will be erected and attached to the mold 310, and then the side insertion structure will be used to push the two side walls to bend to the side walls of the mold 310 to form the side of the three-dimensional bag; then the sealing mechanism is used to connect the joint.

[0054] In this application, the specific form of the side insertion structure is not limited, for example, it can be driven by a driving motor to move the side insertion plate in the width direction so that the side of the three-dimensional bag is bent and attached to the side wall of the mold 310.

[0055] The specific form of the sealing mechanism is not required, for example, it can be a heat sealing mechanism, a pressing mechanism, etc. For non-woven fabric, the sealing mechanism can be an ultrasonic welding mechanism to weld the joint of the bag body. For paper material, the forming device 300 is also provided with a glue spraying mechanism, which sprays glue at the joint of the bag body in advance. When the bag body is completely wrapped to the outside of the mold 310, the pressing mechanism is used to press the joint to make the glue stick.

[0056] Those skilled in the art should understand that the joint position of the three-dimensional bag is not limited, and should be determined according to the production requirements, for example, the joint position of the three-dimensional bag can be located at the bottom wall of the three-dimensional bag, or at the side wall of the three-dimensional bag.

[0057] In this application, for different sizes of bag specifications, different sizes of molds 310 can be used, and of course the mold 310 can also be a structure with adjustable size. The specific form of the adjustable structure is not described in this application.

[0058] Further, in this application, the size of the forming hole between the receiving platforms 320 can be dynamically changed by adjusting the distance between the pair of receiving platforms 320, for example, one of the pair of receiving platforms 320 can be arranged as a structure movable in the width direction, or both of the pair of receiving platforms 320 can be arranged as structures movable in the width direction.

[0059] Specifically, when one of the pair of receiving platforms 320 is arranged in a structure movable along the width direction, in order to ensure the centration of the mold 310 and the forming hole, the mold 310 can also be arranged to be movable along the width direction for adjustment. Specifically, one of the receiving platforms 320 and the mold 310 can be integrated on the same moving plate, and the moving plate is used to move so that the one receiving platform 320 and the mold 310 move synchronously for adjustment, thereby realizing the size adjustment of the forming hole.

[0060] The liftable structure of the mold 310 is not limited, for example, a gear and rack transmission mechanism, a synchronous belt transmission mechanism or a connecting rod mechanism can be used to drive the mold 310 to lift.

[0061] Further, the design of the receiving platform 320 movable along the width direction can realize the adjustment of the forming hole through the cooperation of the guide rail slider, the servo motor drive, the air cylinder drive or the manual adjustment screw rod, so as to meet the forming requirements of different sizes of bag bodies.

[0062] The manufacturing equipment of the three-dimensional bag provided in the present application realizes efficient production of different sizes of bag bodies through the cooperation of the handle fixing station and the forming station. Among them, the pair of handle fixing assemblies 210 in the handle fixing device 200 are arranged opposite to each other along the width direction of the base material, and at least one handle fixing assembly 210 is movably connected to the rack 100 along the width direction. When it is necessary to adjust the size of the bag body, at least one handle fixing assembly 210 is moved to change the distance between the pair of handle fixing assemblies 210, so as to adapt to the base material of different widths and complete the fixing operation of the handle. Further, the mold 310 in the forming device 300 cooperates with the pair of receiving platforms 320, the pair of receiving platforms 320 form a forming hole for the mold 310 to pass through, and at least one receiving platform 320 is movably connected to the rack 100 along the width direction. When forming different sizes of bag bodies, the size of the forming hole is dynamically changed by adjusting the position of at least one receiving platform 320 to match the size requirements of the target bag body.

[0063] Therefore, the manufacturing equipment of the three-dimensional bag provided in the present application realizes the rapid adaptation to the production requirements of different sizes of bag bodies by designing the movable handle fixing assemblies 210 and the receiving platforms 320. Specifically, the mobility of the handle fixing assemblies 210 and the receiving platforms 320 avoids the repeated disassembly and assembly operation of the execution mechanism in the traditional machine adjustment process, thereby reducing the machine adjustment time and mechanical wear. This design enables the bag manufacturing equipment to efficiently switch between different sizes of bag body production tasks, and solves the problem of low production efficiency caused by long machine adjustment period in the prior art.

[0064] The specific structure and arrangement mode of the handle fixing assembly 210 will be further explained below.

[0065] In the present application, as shown inFigure 3 and Figure 4 As shown in FIG. 10, the handle fixing assembly 210 includes a pair of handle fixing components 211 arranged opposite along the length direction of the base material, and the pair of handle fixing components 211 respectively fix and connect the two ends of the handle to the handle fixing position of the base material, and at least one of the pair of handle fixing components 211 is movably connected to the rack 100 along the production line.

[0066] Specifically, the handle fixing component 211 refers to an actuator for realizing the fixed connection of the handle end to the base material, which can adopt a clamping mechanism, a suction mechanism or a hot pressing mechanism, etc. Among them, the clamping mechanism grasps the handle end to the handle fixing position of the base material through mechanical clamps; the suction mechanism can use a vacuum suction cup to adsorb the handle end to move to the handle fixing position of the base material; and then press to make the handle end and the base material gluey fixed, or heat seal to make the handle end and the base material fixed.

[0067] In actual application, the movable connection along the production line refers to an adjustable connection mode realized by linear guide rails, screw transmission or synchronous belt transmission mechanism, etc. The purpose is to enable the handle fixing component 211 to be dynamically adjusted in the length direction (see direction L in FIG. 10) according to the size requirements of the bag body, so as to adapt to the production requirements of different lengths of the two end connection points of the handle. Figure 1

[0068] More specifically, the present scheme realizes the flexible adjustment of the fixing position of the two ends of the handle by arranging a pair of handle fixing components 211 opposite along the length direction of the base material on the rack 100. Among them, at least one handle fixing component 211 has the movability along the production line direction, and this design makes the operator only need to adjust the position of the movable handle fixing component 211 to change the distance between the two end fixing points of the handle when producing three-dimensional bags with different lengths of the two end connection points of the handle. Compared with the traditional structure, the present scheme does not need to repeatedly disassemble and assemble the handle fixing component 211, significantly shortens the machine adjustment time, and improves the production efficiency. At the same time, the adjustable structure cooperates with the overall design of the handle fixing station to form a complete handle fixing system, which can better meet the production requirements of small batch orders.

[0069] Those skilled in the art should understand that at least one of the pair of handle fixing components 211 movably connected to the rack 100 along the production line can be one of the pair of handle fixing components 211 movably connected to the rack 100 along the production line, or both can be movably connected to the rack 100 along the production line, and the movable mode can be realized by similar mechanisms.

[0070] ​As to the handle fixing component 211, in the three-dimensional bag making equipment provided in the present application, each handle fixing component 211 comprises a moving seat 2111, a handle fixing unit 2112 and a handle moving unit 2113; the handle fixing unit 2112 and the handle moving unit 2113 are both arranged on the moving seat 2111, the moving seat 2111 is movably connected to the rack 100 along the length direction, the handle moving unit 2113 moves the end of the handle through the rope passing hole from the lower side of the base material to the upper side of the base material, and the handle fixing unit 2112 fixes the end of the handle at the handle fixing position of the base material.

[0071] Specifically, the moving seat 2111 refers to a structure capable of carrying other functional units and realizing linear displacement, which can adopt a linear guide cooperating with a sliding block or a ball screw pair and the like transmission mechanism. The handle fixing unit 2112 refers to a device for final positioning and fixing of the end of the handle, which can adopt a hot pressing mechanism, an ultrasonic welding head or a pressing mechanism and the like. The handle moving unit 2113 refers to an execution mechanism responsible for transferring the handle from an initial position to a target position, which can adopt a pneumatic push rod, a servo motor driven mechanical arm or a vacuum suction cup and the like structure to realize.

[0072] More specifically, the moving seat 2111 is movably connected to the rack 100 along the length direction, so that the entire handle fixing component 211 can be flexibly adjusted in position according to the size requirement of the bag body, avoiding the equipment wear and tear problem caused by repeated disassembly and assembly in the traditional way. The handle moving unit 2113 realizes the automation operation of the handle installation process by moving the end of the handle through the rope passing hole from the lower side of the base material to the upper side of the base material, which significantly improves the production efficiency and positioning accuracy. The handle fixing unit 2112 immediately performs the fixing action after the end of the handle reaches the specified position, ensuring the reliability and consistency of the connection. This design not only solves the low efficiency problem caused by relying on manual operation in the machine adjustment process, but also forms a complete automatic operation process through the organic cooperation of each unit, effectively shortens the machine adjustment time and improves the adaptability and production stability of the equipment.

[0073] It should be understood by those skilled in the art that when the handle moving unit 2113 moves the end of the handle through the rope passing hole from the lower side of the base material to the upper side of the base material, the handle moving unit 2113 can be arranged as a push plate located below the base material, which pushes the end of the handle to the upper side of the base material by the push plate, or can be arranged as a grabbing clamp located above the base material, which first moves down through the rope passing hole, then clamps the end of the handle, and then resets to clamp the end of the handle to the upper side of the base material.

[0074] In an embodiment, the handle moving unit 2113 is arranged as a pushing mechanism, which is arranged on the moving base 2111 below the plane of the base material and pushes the end of the handle from below the base material to above the base material.

[0075] Specifically, the pushing mechanism refers to a device capable of applying a pushing force in the vertical direction to complete the transfer of the end of the handle, which can adopt a push rod structure driven by a pneumatic cylinder, a cam linkage mechanism or a push plate driven by a linear motor. The pushing mechanism scheme fully utilizes the space layout below the plane of the sheet material by arranging the mechanism below the sheet material and directly pushing the end of the handle upwards, avoiding the design of complex trajectory motion. This structure design makes it only need to fine-tune the position of the pushing mechanism when adjusting the size of the bag body, which can adapt to different width base materials, significantly reducing the disassembly and assembly operations and mechanical wear during machine adjustment.

[0076] In another embodiment, the handle moving unit 2113 is arranged as a clamping mechanism, which is arranged on the moving base 2111 above the plane of the base material, and the clamping head of the clamping mechanism passes through the rope passing hole from above the base material and resets, clamping the end of the handle from below the base material to above the base material.

[0077] Specifically, the clamping mechanism refers to a transfer device with grasping and releasing functions, which can adopt structures such as mechanical claws, vacuum suction cups or electromagnetic suction heads. The clamping mechanism is arranged above the sheet material and uses the precise positioning ability of the clamping head to realize dynamic matching with the position of the rope passing hole, thereby adapting to the production needs of different sizes of three-dimensional bags. The clamping mechanism scheme realizes the precise transfer of the end of the handle by the action logic of the clamping head passing through the rope passing hole from top to bottom and resetting. Especially in the small-batch multi-size production scene, this scheme can quickly adapt to different handle fixing positions without replacing core components, improving the response speed of the equipment to order changes.

[0078] Those skilled in the art should understand that both schemes arrange the handle moving unit 2113 to move synchronously with the moving base 2111, and through the spatial configuration and action logic of the fixed transfer mechanism, the transfer process originally relying on repeated manual debugging is converted into a preset automatic operation, which can fundamentally shorten the machine adjustment period and enhance the applicability of the equipment to the production of multi-size three-dimensional bags.

[0079] Further regarding the structure of the handle fixing assembly 210, it is further noted that in the present application, the pair of handle fixing assemblies 210 are movably connected to the frame 100 along the width direction; each handle fixing assembly 210 further comprises a first moving table 220, and the frame 100 is provided with a first guide rail 230 extending along the width direction, each first moving table 220 is slidingly connected to the first guide rail 230 along the width direction, and each first moving table 220 is provided with a second guide rail extending along the length direction, the moving seat 2111 of the pair of handle fixing components 211 is slidingly connected to the second guide rail; and the frame 100 is provided with a first screw rod driving assembly (not shown) on one side of the first guide rail 230, the screw rod in the first screw rod driving assembly is rotationally connected to the frame 100 along the width direction, and the pair of first moving tables 220 are threadedly connected with the screw rod in the first screw rod driving assembly; the rotation of the screw rod in the first screw rod driving assembly causes the pair of first moving tables 220 to move closer to or away from each other along the first guide rail 230; the first moving table 220 is provided with a second screw rod driving assembly (not shown) on one side of the second guide rail, the screw rod in the second screw rod driving assembly is rotationally connected to the first moving table 220 along the length direction, and the pair of moving seats 2111 are threadedly connected with the screw rod in the second screw rod driving assembly, the rotation of the screw rod in the second screw rod driving assembly causes the pair of moving seats 2111 to move closer to or away from each other along the second guide rail.

[0080] Specifically, the first moving table 220 refers to a platform structure for carrying and moving the handle fixing component 211, which can adopt structures such as linear sliders or ball screws, aiming to provide a stable moving basis. The first guide rail 230 can be understood as a guiding device, which is realized through linear tracks or dovetail grooves, aiming to ensure the accurate movement of the first moving table 220 along the width direction. The second guide rail is an auxiliary guiding mechanism, which can be through similar linear tracks, aiming to support the flexible adjustment of the handle fixing component 211 along the length direction. The first screw rod driving assembly and the second screw rod driving assembly respectively refer to transmission mechanisms for driving the first moving table 220 and the moving seat 2111, which can be structures such as motor linkage trapezoidal screws or ball screws, aiming to provide accurate linear motion control.

[0081] More specifically, the scheme realizes the synchronous adjustment function of the handle fixing assembly 210 in the width direction through the cooperation of the first mobile station 220 and the first guide rail 230, thereby avoiding the asymmetric problem caused by unilateral adjustment. At the same time, the cooperation of the second guide rail arranged on the first mobile station 220 and the mobile seat 2111 further enhances the positioning accuracy of the handle fixing point in the length direction, meeting the needs of different handle lengths. The first screw rod driving assembly drives a pair of first mobile stations 220 to move closer to or away from each other along the first guide rail 230 through the rotation of the screw rod. This design takes advantage of the high precision characteristics of threaded transmission, significantly reducing the need for manual disassembly and assembly. In addition, the second screw rod driving assembly controls the position change of the mobile seat 2111 on the second guide rail through the rotation of the screw rod, ensuring the accurate positioning of the handle fixing point in the length direction.

[0082] It should be understood that, regarding the first screw rod driving assembly driving a pair of first mobile stations 220 to move closer to or away from each other along the first guide rail 230 through the rotation of the screw rod, in specific implementation, a pair of first mobile stations 220 can be individually provided with a first screw rod driving assembly, or a pair of first mobile stations 220 can use the same first screw rod driving assembly. At this time, the first screw rod driving assembly is provided with opposite threads, i.e., when the same screw rod rotates, it can make a pair of first mobile stations 220 move closer to or away from each other synchronously.

[0083] In this application, regarding the arrangement of the receiving platform 320, it should be noted that, as shown in Figure 1 、 Figure 2 、 Figure 5 , a pair of receiving platforms 320 are movably connected to the rack 100 in the width direction; each receiving platform 320 includes a second mobile station 330 fixedly connected to the panel, and the rack 100 is provided with a third guide rail 340 extending in the width direction at the position of the forming station; each second mobile station 330 is slidingly connected to the third guide rail 340 in the width direction; the rack 100 is provided with a third screw rod driving assembly 350 on one side of the third guide rail 340, the screw rod in the third screw rod driving assembly 350 is rotationally connected to the rack 100 in the width direction, and a pair of second mobile stations 330 are threadedly connected to the screw rod in the third screw rod driving assembly 350; the rotation of the screw rod in the third screw rod driving assembly 350 makes a pair of second mobile stations 330 move closer to or away from each other in the width direction.

[0084] Specifically, the receiving platform 320 refers to a structure for supporting and positioning the base material to complete the three-dimensional bag forming, which can be made of metal plate or high-strength composite material, aiming to provide a stable forming base. In practical application, the second moving table 330 can be a mechanical platform with a sliding block structure, which realizes precise linear motion by cooperating with the third guide rail 340 through the sliding block. The third guide rail 340 can adopt a precision guide mechanism such as a linear guide rail or a ball guide rail, aiming to ensure the stability and accuracy of the moving process. The third screw drive assembly 350 can be understood as a transmission mechanism including a motor, a screw rod and a nut, which drives the screw rod to rotate through the motor, drives the nut and the moving table connected thereto to realize linear displacement.

[0085] More specifically, this scheme realizes rapid adjustment of the forming hole width through the design of synchronous movement of the two platforms. A pair of receiving platforms 320 can move in the width direction, with higher flexibility. The face plate of each receiving platform 320 forms a stable overall structure with the second moving table 330, which not only ensures the stability of the forming process, but also realizes the overall displacement function. The third guide rail 340 provides precise guidance and constraint for the moving table, effectively preventing deviation during displacement, which is beneficial to the forming quality of the bag body.

[0086] It should be understood that the third screw drive assembly 350 can drive two second moving tables 330 simultaneously through the same screw rod, realizing synchronous and symmetrical movement of the two platforms, and the adjustment accuracy is better.

[0087] The third screw drive assembly 350 can also be provided with two screw rods and two motors, and the two screw rods are respectively in transmission connection with the two second moving tables 330, and the two motors are respectively used to drive the two screw rods to rotate, which is more conducive to the installation and arrangement of the third screw drive assembly 350.

[0088] Based on the above scheme, when the forming hole width needs to be adjusted, the synchronous movement of the pair of second moving tables 330 can be realized by controlling the motor of the third screw drive assembly 350 to reverse. The accuracy and synchronization characteristics of screw transmission make the forming hole width adjustment rapid and uniform, effectively solving the problem of repeatedly manually disassembling and assembling the connecting piece during adjustment, and significantly improving the production efficiency.

[0089] In this application, the manufacturing equipment of the three-dimensional bag is not limited to the above structure, further, in combination with Figure 1 、 Figure 2 、 Figure 6As shown, the manufacturing device further comprises a folding edge station between the handle fixing station and the forming station, and a folding edge device 400 is arranged on the folding edge station, which is used to fold the two side edge regions of the base material upwards to form a bag opening folding edge; the folding edge device 400 comprises a pair of folding edge assemblies 410 arranged on the rack 100 in the width direction, and at least one of the pair of folding edge assemblies 410 is movably connected to the rack 100 in the width direction.

[0090] Specifically, the folding edge station refers to a station specially used for processing the two side edges of the sheet material to form a bag opening folding edge in the three-dimensional bag manufacturing process, which can adopt a mechanical folding edge mechanism or a pneumatic folding edge mechanism. Among them, the folding edge device 400 refers to a functional module that can complete the folding action of the edge of the sheet material, which can be through a roller folding edge mechanism, a pressing plate folding edge mechanism or a combined folding edge mechanism. In practical application, the pair of folding edge assemblies 410 refers to two functional units arranged on the two sides of the sheet material respectively to complete the folding operation, which can be realized by a synchronous driving mechanism or an independent driving mechanism to realize position adjustment.

[0091] Those skilled in the art should understand that at least one of the pair of folding edge assemblies 410 is movably connected to the rack 100 in the width direction, specifically, one of the pair of folding edge assemblies 410 can be movably connected to the rack 100 in the width direction, or both of the pair of folding edge assemblies 410 can be movably connected to the rack 100 in the width direction.

[0092] More specifically, the scheme adds a folding edge station between the handle fixing station and the forming station, which ensures the continuity of the production process. The folding edge device 400 can automatically complete the folding operation of the two side edges of the sheet material to form a stable bag opening folding edge structure, which is beneficial to improve the bag opening strength of the bag body. Especially, the design that at least one of the pair of folding edge assemblies 410 can move in the width direction enables the device to quickly adjust the folding edge position according to the change of the bag body width without complicated disassembly and assembly operation. This design significantly shortens the machine adjustment time and avoids the wear of the device connecting parts caused by frequent disassembly and assembly.

[0093] Regarding the arrangement mode of the folding edge assembly 410, at least one folding edge assembly 410 comprises a third moving table 420 movably connected to the rack 100 in the width direction through a fourth screw rod driving assembly 430. The third moving table 420 refers to a platform structure capable of carrying and driving the mechanism installed thereon to move accurately, and the fourth screw rod driving assembly 430 can be driven in a linear guide rail and servo motor or screw rod transmission mode.

[0094] In one embodiment of the present application, the at least one folding assembly 410 comprises a turning mechanism and a positioning mechanism, both of which are arranged on the third moving table 420. The turning mechanism is arranged on the third moving table 420 close to the edge of the base material, and the positioning mechanism is arranged on the third moving table 420 close to the inner side of the base material, and presses on the inner side of the crease line of the base material. The turning mechanism turns the two side edge regions of the base material upward to form the bag opening flaps.

[0095] Specifically, the turning mechanism is a device for applying a rotating torque to the edge of the sheet material to complete the folding action, which can be realized by a rotary cylinder or a cam mechanism. The positioning mechanism refers to a device for fixing the base material to ensure the folding accuracy, which can adopt a vacuum suction plate or a pressing plate, etc. In this scheme, the positioning mechanism is located on the inner side of the base material to fix the base material, and the turning mechanism is close to the edge of the base material to perform the folding action.

[0096] In another embodiment of the present application, the at least one folding assembly 410 comprises a lifting mechanism, a side pushing mechanism and a positioning mechanism. The lifting mechanism is arranged on the third moving table 420 below the folding region of the base material, the side pushing mechanism is arranged on the third moving table 420 on one side of the base material in the width direction, and the positioning mechanism presses on the inner side of the crease line of the base material. The lifting mechanism pushes the folding region to bend by a preset angle, and the side pushing mechanism pushes the folding region bent by the preset angle again in the width direction to form the bag opening flaps.

[0097] Specifically, the lifting mechanism is a device for applying a vertical force from the bottom of the sheet material to realize the preliminary bending, which can be a hydraulic cylinder or an electric push rod. The side pushing mechanism is a device for applying a lateral pushing force to the sheet material that has been preliminarily bent to complete the final folding, which can be a linear module or a pneumatic sliding table.

[0098] In use, the positioning mechanism first fixes the position of the base material, then the lifting mechanism completes the preliminary bending, and finally the side pushing mechanism performs the secondary bending to form the final bag opening flaps. This step-by-step operation mechanism can better adapt to the folding requirements of different complexity.

[0099] In the present application, the manufacturing equipment of the three-dimensional bag is not limited to the above structure. Further, in combination with the above-mentioned folding mechanism, Figure 1 、 Figure 2 、 Figure 7As shown, the three-dimensional bag making equipment further comprises a head card fixing station arranged on the upstream side of the handle fixing station. The head card fixing station is provided with a head card fixing device 500 for fixing a head card on the edge folding region of the base material and / or the inner side of the base material body. The head card fixing device 500 comprises a pair of head card fixing assemblies 510 arranged on the frame 100 in the width direction, and at least one of the pair of head card fixing assemblies 510 is movably connected to the frame 100 in the width direction.

[0100] Specifically, the head card fixing station refers to a station specially used for fixing a head card in the three-dimensional bag making process. The head card refers to a card fixed in the bag body near the opening to improve the firmness of the handle fixing. The head card fixing device 500 can be understood as an integrated functional unit that can stably fix the head card at the target position of the base material through mechanical clamping, adsorption or other physical fixing methods. The pair of head card fixing assemblies 510 refers to two symmetrically arranged functional units that can realize relative movement in the width direction through screw driving, linear guide sliding or cylinder pushing, etc. The purpose is to dynamically adjust the head card fixing position according to the size change of the bag body.

[0101] In detail, the head card fixing station is arranged on the upstream side of the handle fixing station. The head card fixing device 500 cooperates with the pair of head card fixing assemblies 510 to realize accurate fixing of the edge folding region of the sheet material and the inner side of the sheet material body. When it is necessary to adjust the head card fixing position, at least one of the pair of head card fixing assemblies 510 can move in the width direction. This design is based on the actual demand of the size change of the bag body, so that the assembly can be directly moved to the target position without manual disassembly and assembly, which greatly shortens the machine adjustment time and reduces the mechanical wear. In addition, the head card fixing device 500, together with other stations such as the handle fixing device 200 and the forming device 300, constitutes a complete three-dimensional bag making equipment. The reasonable layout and functional connection between the stations significantly improve the overall adaptability and production efficiency of the equipment.

[0102] Those skilled in the art should understand that, for at least one of the pair of head card fixing assemblies 510 movably connected to the frame 100 in the width direction, one of the pair of head card fixing assemblies 510 can be movably connected to the frame 100, or both of the pair of head card fixing assemblies 510 can be movably connected to the frame 100.

[0103] Regarding the head card fixing assembly 510, at least one head card fixing assembly 510 comprises a fourth moving table 520, a head card storage component 530, and a head card grabbing component 540; the fourth moving table 520 is movably connected to the rack 100 along the width direction by a fifth screw rod driving assembly 550, the head card storage component 530 is arranged on the fourth moving table 520 for storing head cards, and the head card grabbing component 540 is arranged on the fourth moving table 520 at one side of the head card storage component 530, and is used for grabbing the head cards stored in the head card storage component 530 one by one to the base material, for example, the head cards can be placed in the edge folding area, or the head cards can be placed on the inner side of the base material body in the edge folding area, or the head cards can be placed on both the edge folding area and the inner side of the base material body in the edge folding area.

[0104] Specifically, the fourth moving table 520 refers to a platform structure capable of carrying other functional components and realizing accurate position adjustment, which can realize movement along the width direction through a screw rod transmission mechanism, a linear guide rail system, or a synchronous belt driving mechanism. The head card storage component 530 can be understood as a container or a support structure for storing head cards, which can be internally provided with a layered storage grid or an elastic compression mechanism to ensure the orderly arrangement and stable supply of the head cards during transportation. The head card grabbing component 540 is an end tool, which can adopt a vacuum suction cup, a mechanical clamping jaw, or an electromagnetic adsorption device to realize reliable grabbing and accurate placement of the head cards.

[0105] More specifically, when the bag size changes, the fourth moving table 520 automatically adjusts the position along the width direction through the fifth screw rod driving assembly 550, which does not require manual intervention and significantly shortens the machine adjustment time. The cooperation of the head card storage component 530 and the head card grabbing component 540 realizes the automatic supply and positioning of the head cards, wherein the head card storage component 530 continuously provides the head cards, and the head card grabbing component 540 accurately transfers the head cards to the specified position according to the preset program. This design not only avoids the mechanical wear caused by frequent disassembly and assembly in the traditional way, but also ensures the rapid response capability when switching different sizes of bags. In addition, this scheme, together with other movable components in the above-mentioned three-dimensional bag making equipment, forms a complete automatic adjustment system, so that the entire bag making process can flexibly adapt to the production needs of small batch orders, greatly improving the adaptability and production efficiency of the equipment.

[0106] Those skilled in the art should understand that the setting mode of the moving table is not limited to the screw rod driving assembly, but can also use other similar linear driving mechanisms, which does not deviate from the protection scope of the present application.

[0107] Further, in the present application, the fourth screw rod driving assembly 430 and the fifth screw rod driving assembly 550 can adopt a similar structure and setting mode as the first screw rod driving assembly.
