Description

Technical Field

[0001] The invention relates to the technical field of bag making machines, in particular to a breakable belt type heat-insulating vertical bag making machine. Background Art

[0002] Currently, non-woven packaging bags have evolved into a variety of styles: punched bags, tote bags, vest bags, zipper bags, and three-dimensional bags. With the exception of three-dimensional bags, all other bag styles are now produced through high-speed automation. The current state of the art for automated production of three-dimensional bags and related equipment is patented over the past 20 years, with patent numbers ZL2010020486.X and ZL201310046052.8, which have enabled the automated production of non-woven three-dimensional bags.

[0003] The existing non-woven three-dimensional bag making machine mainly consists of the following devices: a feeding device, a folding device, a handle pressing device, a creasing device, a cutting device, a forming and welding device, a bag folding device, a bag sorting device, and a traction roller group that pulls the material along the feeding devices. Among them, the folding device can process the folded edge at the mouth of the three-dimensional bag; the handle pressing device irons the handle at the folded edge; the creasing device is used to creasing the non-woven fabric; the cutting device performs preliminary bag separation and cutting after the handle is pressed; the forming and welding device forms and welds the cut non-woven fabric along the creasing area; the bag folding device is installed after the forming and welding device and folds the inner edges of the welded three-dimensional bag on both sides.

[0004] Different specifications and types of bags require different cutting and punching spacings during the cutting or punching process. At present, in order to achieve the cutting and punching of three-dimensional bags of different specifications and types, the cutting device or the punching device is linked to a hand wheel. The position of the cutting device or the punching device is manually adjusted by the hand wheel to cut and punch three-dimensional bags of different specifications and types. The operation is extremely inconvenient. The most important thing is that manual adjustment cannot ensure the cutting accuracy, the error is large, which affects the three-dimensional bag and takes a long time.

[0005] There is also a problem with the existing non-woven three-dimensional bag making machine: as mentioned above, the existing non-woven three-dimensional bag can be processed into a three-dimensional bag, but the bag opening of the three-dimensional bag only has a folded edge and cannot be pasted with tape. Therefore, when the three-dimensional bag is in use, the bag opening is open. During takeout delivery, bumping, running, etc., the items in the three-dimensional bag are very easy to spill out. Therefore, the market demand for three-dimensional bags is to set tape at the bag opening to seal the bag opening.

[0006] Currently, there are tools available on the market that can be used for gluing and cutting. For example, the document with publication number "CN215364160U" discloses the following two technical solutions:

[0007] A tape cutting device mainly includes a fixed plate, a swing arm plate, a first transmission wheel, a second transmission wheel, a third transmission wheel, a cutter, a manipulation device and a return device. The connection relationship between the above components is as shown in the appendix of the above document. Figure 1-4 This technical solution has the following defects: (1) During the transportation of the tape, the adhesive surface of the tape will contact the conveyor wheel, causing adhesion and wrinkling. Moreover, after long-term use of the rubber wheel, excessive adhesive will accumulate on the surface, which is easy to adhere to dust and affect the adhesive strength of the tape surface. (2) During cutting, the cutter does not move, and the operating device drives the swing arm plate to swing upward, and the tape moves relative to the cutter to cut. This cutting method requires a high degree of tension on the tape. If the tape is loose as a whole, that is, when the tension is small or there is no tension, the cutter cannot cut the tape, so the cutting operation is highly unstable. (3) The operating device needs to be manually controlled for cutting, and fully automatic cutting is not possible.

[0008] The glue applicator mainly includes the aforementioned tape cutting device, handle, tape reel, front guide wheel, and rear guide wheel. The cutting blade of the cutter is positioned higher than the lower outer common tangent line of the front and rear guide wheels. This technical solution has the following defects: (1) During gluing and cutting, the glue applicator as a whole needs to move in a straight line, while the fabric does not move. This type of gluing cannot achieve continuous cutting and requires manual control of the entire glue applicator to move. This operation is cumbersome and cannot be adapted to fully automatic operation. Moreover, it is difficult to ensure that the path of the glue applicator is straight during movement, and the tape is prone to wrinkling and skewing.

[0009] In summary, the above-mentioned gluing devices or equipment cannot be reasonably applied to the existing high-speed non-woven three-dimensional bag making machines, and cannot achieve fully automatic processing. Therefore, it is necessary to improve the existing gluing devices to adapt to the existing non-woven three-dimensional bag making machines. Summary of the Invention

[0010] The technical problem to be solved by the present invention is to address the deficiencies of the above-mentioned prior art and provide a breakable belt type heat-insulating three-dimensional bag making machine, which is equipped with a reciprocating lifting mechanism to ensure that the spacing of materials in the punching, cutting and other processes is an integer multiple of the spacing of the required three-dimensional bags, and automatically adjusts according to the different specifications and types of three-dimensional bags; further, an automatic breakable belt type gluing device is provided to solve the problem that the bag making machine in the prior art cannot be glued, and it is reasonably combined with the existing bag making machine to realize fully automatic gluing and bag making integration without manual operation.

[0011] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a breakable belt type heat-insulating vertical bag making machine, comprising a frame and a feeding device, a folding device, a handle pressing device, an indentation device, a punching device, a one-time bag making and forming device, a bag folding device, and a traction roller group for pulling and transporting the material along each device, which are sequentially arranged on the frame. It is characterized in that the frame is also provided with a reciprocating lifting mechanism distributed between the handle pressing device and the indentation device; the reciprocating lifting mechanism includes a lifting roller, and the two ends of the lifting roller are linked with a lifting slider, the lifting slider is threadedly linked with a vertical screw rod, and the gear at the end of the vertical screw rod is meshed with a horizontal screw rod.

[0012] The above technical solution uses a reciprocating lifting mechanism between the handle pressing device and the creasing device to automatically adjust the material. It can be adaptively adjusted according to the specifications of the three-dimensional bag to be processed, so that the spacing of the materials in the punching and cutting processes is an integer multiple of the spacing of the three-dimensional bag to be processed. There is no need to manually adjust the position of the punching and cutting knives, etc., which improves the working stability of the punching and cutting knives and other processes, and improves the adaptability of the overall equipment. It can also realize fully automatic production and adjustment, and automatically adjust according to different specifications of three-dimensional bags. Among them, the end of the transverse screw can be linked to a servo motor, and the movement of the transverse screw can be precisely controlled by the servo motor.

[0013] The above-mentioned breakable belt type heat-insulating vertical bag making machine can be further configured as follows: the end of the lifting slider is linked with a guide rod, and the central axes of the guide rod and the vertical screw rod are parallel to each other.

[0014] By adopting the above technical solution and setting a guide rod, the working stability of the lifting slider is improved, ensuring that the movement path of the lifting slider always remains consistent.

[0015] The above-mentioned breakable belt type heat-insulating vertical bag making machine can be further configured as follows: an automatic breakable belt type gluing device is provided between the folding device and the handle pressing device; the automatic breakable belt type gluing device includes a feeding rubber roller, a gluing mechanism, and a cutter, the feeding rubber roller is hinged to the upper part of the frame, and the gluing mechanism and cutter are distributed at the lower part of the frame; the gluing mechanism includes a first floating swing arm, one end of which is hingedly linked to a first hinge shaft, and the first hinge shaft is installed on the frame; the cutter is linked to a second floating swing arm, the middle part of the first floating swing arm is hinged to the middle part of the first floating swing arm, the middle part of the first floating swing arm is linked to a cylinder, and the end of the cylinder is hinged to the frame; one end of the second floating swing arm is linked to a first pressure spring, and the cutter is distributed at the other end of the second floating swing arm; the frame is linked to a second hinge shaft distributed below the first hinge shaft, and the end of the second floating swing arm that is linked to the first pressure spring extends toward the first hinge shaft until it is detachably engaged above the second hinge shaft.

[0016] The above technical solution is adopted to solve the problem that the bag making machine in the prior art cannot glue by setting an automatic belt-breaking gluing device, and it is reasonably combined with the existing bag making machine to realize fully automatic gluing and bag making integration without manual operation; and the automatic belt-breaking gluing device is set, so that the traditional tape has no breakpoints (that is, the tape and the edge of the roll material are continuously adhered without breakpoints), and is changed into the current "one section at a time" form. By adjusting the installation position of the punching device, the punching device is used to punch holes between each two adjacent groups of glue, saving tape.

[0017] When gluing, the cylinder pushes the end of the first floating swing arm downward. At the same time, since the middle part of the second floating swing arm is hinged with the middle part of the first floating swing arm, the second floating swing arm follows the end of the first floating swing arm to be pressed down. At the same time, the first pressure spring linked to the other end of the second floating swing arm is stretched (the first pressure spring in the stretched state accumulates a certain rebound force), and the first floating swing arm is pressed down until the tape is adhered to the material to perform the gluing work; after the gluing is completed and the cutting work needs to be performed, the cylinder drives the first floating swing arm to lift up. At the same time, since the middle part of the second floating swing arm is hinged with the middle part of the first floating swing arm, the second floating swing arm follows the end of the first floating swing arm to be lifted up. At the same time, the first pressure spring is not restricted by the stretching force and performs a rebound motion, and drives the second floating swing arm to rotate around the hinge of the second floating swing arm and the first floating swing arm, so that the cutter follows the end of the first floating swing arm to press down until the cutter contacts the tape to achieve the cutting work.

[0018] The automatic tape-breaking gluing device adopts the connection structure provided by the above-mentioned technical solution. Compared with the existing technology, the cutting method is changed from the cutting method in which the tape actively moves and the cutter is relatively stationary to the cutting method in which both the tape and the cutter move relative to each other. The cutting stability is good and the cutting efficiency is high. Furthermore, the design is ingenious. Only one set of cylinders is needed to synchronously drive the first floating swing arm, the second floating swing arm and the cylinder. The whole device is suitable for fully automatic production without manual operation, saving manpower and reducing human labor intensity.

[0019] The above-mentioned breakable belt type heat-insulating vertical bag making machine can be further configured as follows: the first floating swing arm is linked to a suction component distributed near one end of the cutter, the suction component includes a relatively distributed tape unloading plate and a tape loading plate, and the tape loading plate is provided with a plurality of groups of suction holes, the suction holes are distributed on the end surface facing the tape unloading plate, and the tape loading plate is linked to a suction source that can be conductively connected to the suction holes.

[0020] By adopting the above technical solution, the tape loading plate and the tape unloading plate both guide and transport the material, making it easier for the tape to be bonded to the bag opening along a predetermined route; further, a suction component is added to the tape loading plate to generate suction force on the non-glue surface of the tape, and the non-glue surface of the tape is adsorbed on the tape loading plate to prevent the tape from adhering to the tape unloading plate, further preventing wrinkles from being generated during gluing; wherein, the suction source can be a pneumatic component.

[0021] The above-mentioned breakable belt type heat-insulating vertical bag making machine can be further configured as follows: the first floating swing arm is linked to a gluing pressure roller distributed on the discharge side of the tape blanking plate.

[0022] By adopting the above technical solution, when the tape is transported at the junction of the tape blanking plate and the material, the gluing roller can flatten the tape and adhere it to the material to assist in gluing.

[0023] The above-mentioned breakable belt type heat-insulating vertical bag making machine can be further configured as follows: the first floating swing arm is linked to a first detection electric eye distributed on the feeding side of the tape blanking plate.

[0024] By adopting the above technical solution, a first detection electric eye is set to detect the lack of material in real time, making it convenient for people to replenish the material in time.

[0025] The above-mentioned breakable belt type heat-insulating vertical bag making machine can be further configured as follows: a second hinge shaft is provided between the middle of the feeding rubber roller and the frame, a second pressure spring is sleeved on the second hinge shaft, and the end of the second pressure spring is in contact with the feeding rubber roller.

[0026] By adopting the above technical solution, a second pressure spring is set up to continuously apply pressure to the loading rubber roller along the axial direction of the loading rubber roller during the transportation process of the loading rubber roller, so that the adhesion force between the material and the tape is mainly used as the transportation force of the loading rubber roller during transportation, thereby ensuring that the tape remains in a tensioned state, avoiding the tape from becoming loose, preventing wrinkles, and ensuring smooth adhesive application.

[0027] The above-mentioned breakable belt type heat-insulating vertical bag making machine can be further configured as follows: the automatic breakable belt type gluing device also includes a second detection electric eye installed on the frame and distributed between the feeding rubber roller and the gluing mechanism.

[0028] By adopting the above technical solution and setting a second detection electric eye, the material shortage situation can be detected in real time at the discharge point of the loading rubber roller, which further facilitates people to replenish materials in time.

[0029] The above-mentioned breakable belt type heat-insulating vertical bag making machine can be further configured as follows: the automatic breakable belt type gluing device also includes a feed pressing plate, which is detachably installed under the frame and distributed on the feed side of the frame.

[0030] By adopting the above technical solution, the feed pressing plate is used to guide and transport materials such as three-dimensional bags, so that the bag openings of the three-dimensional bags and other materials can be transported along a predetermined direction until they are bonded to the tape.

[0031] The above-mentioned breakable belt type heat-insulating vertical bag making machine can be further configured as follows: the automatic breakable belt type gluing device also includes a discharge flattening roller, the discharge flattening roller is distributed on the discharge side of the frame, and the discharge flattening roller is linked to a lifting cylinder.

[0032] By adopting the above technical solution, the discharge flattening roller is mainly used to perform tasks such as tape compacting and material flattening on the bag openings of materials such as three-dimensional bags after gluing, thereby making the adhesion between the tape and the material more stable.

DETAILED DESCRIPTION

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] like Figure 1 The illustrated, breakable-belt, insulated, vertical bag-making machine comprises a frame, and sequentially mounted thereon are a feeding device 1, an edge-folding device 2, a handle pressing device 4, a creasing device 6, a punching device 7, a primary bag-forming device 8, and a bag-folding device 10, along with a traction roller assembly for pulling the material along the various devices. The bag-making machine can also be equipped with a label tracking mechanism 9, positioned between the primary bag-forming device 8 and the punching device 7, to position the material belt. A bag sorting mechanism 11 can also be positioned behind the bag-folding device 10 to stack and organize the folded bags.

[0045] like Figure 2 As shown, the frame is also equipped with a reciprocating lifting mechanism 5, which is distributed between the handle pressing device 4 and the creasing device 6. This reciprocating lifting mechanism 5 includes a lifting roller 51, with lifting sliders 52 connected at both ends. The lifting slider 52 is threadedly connected to a vertical screw 53, and the end of the vertical screw 53 is gear-engaged with a transverse screw 54. The end of the lifting slider 52 is connected to a guide rod 55, and the central axis of the guide rod 55 and the vertical screw 53 are parallel. The provision of the guide rod 55 improves the operating stability of the lifting slider 52 and ensures that the movement path of the lifting slider 52 is always consistent.

[0046] The above technical solution is adopted, and the reciprocating lifting mechanism 5 between the handle pressing device 4 and the creasing device 6 is used to automatically adjust the material. The reciprocating lifting mechanism 5 is adaptively adjusted according to the specifications and types of the three-dimensional bags to be processed, so that the spacing of the materials in the punching and cutting processes is an integer multiple of the spacing of the three-dimensional bags to be processed. There is no need to manually adjust the position of the punching and cutting knives, etc., which improves the working stability of the punching and cutting knives and other processes, and improves the adaptability of the overall equipment. It can also realize fully automatic production and adjustment, and automatically adjust according to different specifications and types of three-dimensional bags. Among them, the end of the transverse screw rod 54 can be linked to a servo motor, and the movement of the transverse screw rod 54 is precisely controlled by the servo motor.

[0047] like Figures 3 to 7As shown, an automatic belt-breaking gluing device 3 is provided between the folding device 2 and the handle pressing device 4; the automatic belt-breaking gluing device 3 includes a feeding rubber roller 31, a gluing mechanism 32, and a cutter 33. The feeding rubber roller 31 is hinged to the upper part of the frame, and the gluing mechanism 32 and the cutter 33 are distributed at the lower part of the frame; the gluing mechanism 32 includes a first floating swing arm 321, one end of which is hingedly linked to a first hinge shaft 322, and the first hinge shaft 322 is installed on the frame; the cutter 33 is linked to a second floating swing arm 323, and the first floating swing arm 3 The middle part of 21 is hinged to the middle part of the first floating swing arm 321, and the middle part of the first floating swing arm 321 is linked to a cylinder 34, and the end of the cylinder 34 is hinged to the frame; one end of the second floating swing arm 323 is linked to a first pressure spring 325, and the cutter 33 is distributed at the other end of the second floating swing arm 323; the frame is linked to a second hinge shaft 324 distributed below the first hinge shaft 322, and the end of the second floating swing arm 323 that is linked to the first pressure spring 325 extends toward the first hinge shaft 322 until it is detachably connected to the top of the second hinge shaft 324. During the gluing process, the cylinder 34 pushes the end of the first floating swing arm 321 downward. At the same time, since the middle of the second floating swing arm 323 is hinged to the middle of the first floating swing arm 321, the second floating swing arm 323 follows the end of the first floating swing arm 321 and is pressed downward. At the same time, the first pressure spring 325 linked to the other end of the second floating swing arm 323 is stretched (the first pressure spring in the stretched state has a certain resilience), and the first floating swing arm 321 is pressed downward until the adhesive tape is attached to the material, and the gluing process is completed. When the gluing is completed and the cutting process needs to be performed, the cylinder 34 drives the The first floating swing arm 321 is moved upward. At the same time, since the middle part of the second floating swing arm 323 is hinged to the middle part of the first floating swing arm 321, the second floating swing arm 323 follows the end of the first floating swing arm 321 to rise. At the same time, the first pressure spring 325 is not restricted by the tensile force and rebounds, driving the second floating swing arm 323 to rotate around the hinge between the second floating swing arm 323 and the first floating swing arm 321, so that the cutter 33 follows the end of the first floating swing arm 321 to press down until the cutter 33 contacts the tape, thereby completing the cutting work.

[0048] The above technical solution is adopted to solve the problem that the bag making machine in the prior art cannot glue by setting the automatic tape-breaking glue-applying device 3, and is reasonably combined with the existing bag making machine to realize the integration of fully automatic glue-applying and bag-making without manual operation; and the automatic tape-breaking glue-applying device is set, so that the traditional tape has no breakpoints (that is, the tape and the edge of the roll are continuously adhered without breakpoints), and is changed to the current "one section at a time" form. By adjusting the installation position of the punching device, the punching device is used to punch holes between each two adjacent groups of glue, saving tape, such as Figure 8As shown, the accompanying figure is a schematic diagram of the punching device punching the material, punching in a position without tape, and the punching device is provided with a hand wheel, rack and other mechanisms to adjust the installation position of the punching device. Furthermore, due to the connection structure provided by the above technical solution, the automatic tape-breaking gluing device 3 changes the cutting method compared to the existing technology, from the cutting method in which the tape actively moves and the cutter 33 is relatively stationary, to the cutting method in which both the tape and the cutter 33 are in relative motion, which has good cutting stability and high cutting efficiency. Furthermore, the design is ingenious, and only one set of cylinders 34 is required to synchronously drive the first floating swing arm 321, the second floating swing arm 323, and the cylinder 34. The whole device is suitable for fully automatic production, without manual operation, saving manpower and reducing human labor intensity.

[0049] The first floating swing arm 321 is linked to a suction component 35 distributed near one end of the cutter 33. The suction component 35 includes a tape unloading plate 351 and a tape loading plate 352 that are relatively distributed. The tape loading plate 352 is provided with a plurality of suction holes 3521. The suction holes 3521 are distributed on the end surface facing the tape unloading plate 351. The tape loading plate 352 is linked to a suction source that can be conductively connected to the suction holes 3521. The tape loading plate 352 and the tape unloading plate 351 guide and transport the material, making it easier for the tape to be bonded to the bag opening along a predetermined route. A suction component 35 is further provided on the tape loading plate 352 to generate suction force on the non-adhesive surface of the tape, so that the non-adhesive surface of the tape is adsorbed on the tape loading plate 352, preventing the tape from being bonded to the tape unloading plate 351, and further preventing wrinkles from being generated during gluing. The suction source can be a pneumatic component.

[0050] The first floating swing arm 321 is linked with a gluing roller 36 distributed on the discharge side of the tape blanking plate 351. When the tape is transported at the junction of the tape blanking plate 351 and the material, the gluing roller 36 can flatten the tape and adhere it to the material to assist in gluing.

[0051] The first floating swing arm 321 is linked with a first detection electric eye 37 distributed on the feeding side of the tape blanking plate 351. By setting the first detection electric eye 37, it is used to detect the lack of material in real time, making it convenient for people to replenish the material in time.

[0052] A second hinge shaft 324 is provided between the middle portion of the feeding roller 31 and the frame. A second pressure spring 38 is sleeved on the second hinge shaft 324, with the end of the second pressure spring 38 engaging and abutting the feeding roller 31. The second pressure spring 38 continuously applies pressure to the feeding roller 31 along its axis during transportation. This allows the feeding roller 31 to primarily utilize the adhesive force between the material and the tape as its transport force, thereby ensuring that the tape remains taut, preventing the tape from becoming loose and wrinkling, and ensuring smooth application.

[0053] The automatic tape-breaking gluing device 3 also includes a second detection electric eye 39 mounted on the frame and distributed between the feeding rubber roller 31 and the gluing mechanism 32. By setting the second detection electric eye 39, the material shortage situation can be detected in real time at the discharge point of the feeding rubber roller 31, further facilitating people to replenish materials in time.

[0054] The automatic tape-breaking gluing device 3 also includes a feed plate 391, which is removably mounted below the frame and located on the feed side of the frame. The feed plate 391 is used to guide and transport materials such as three-dimensional bags, ensuring that the bag openings of the bags are transported in a predetermined direction until they are bonded to the tape.

[0055] The automatic tape-breaking gluing device 3 also includes a discharge flattening roller 392 located on the discharge side of the frame and linked to a lifting cylinder 393. The discharge flattening roller 392 is primarily used to compact the tape and flatten the material at the opening of the glued three-dimensional bag, thereby ensuring a more stable bond between the tape and the material.

[0056] The working principle of the automatic tape-breaking gluing device 3 is as follows: the coil is smoothly moved to the bottom of the tape unloading plate 351 under the traction of the feeding pressure plate 391. The tape is transported by the feeding rubber roller 31 to the space between the tape loading plate 352 and the tape unloading plate 351 under the transportation of the traction roller group. The air suction component 35 adsorbs the non-glue surface of the tape onto the tape loading plate 352. During gluing, the cylinder 34 pushes the end of the first floating swing arm 321 downward. At the same time, since the middle part of the second floating swing arm 323 is hinged to the middle part of the first floating swing arm 321, the second floating swing arm 323 follows the end of the first floating swing arm 321 downward. At the same time, the first pressure spring 325 linked to the other end of the second floating swing arm 323 is stretched (the first pressure spring in the stretched state accumulates a certain amount of rebound force). The first floating swing arm 321 is pressed down until the tape is attached to the material. Then the gluing pressure roller 36 presses the tape onto the coil for gluing. After a single gluing operation is completed, the cutting process is required. During operation, the cylinder 34 drives the first floating swing arm 321 to lift up. At the same time, since the middle part of the second floating swing arm 323 is hinged to the middle part of the first floating swing arm 321, the second floating swing arm 323 follows the end of the first floating swing arm 321 to lift up. At the same time, the first pressure spring 325 is not restricted by the tensile force and rebounds, driving the second floating swing arm 323 to rotate around the hinge between the second floating swing arm 323 and the first floating swing arm 321, so that the cutter 33 follows the end of the first floating swing arm 321 to press down until the cutter 33 contacts the tape, thereby completing the cutting operation.

[0057] Working principle of the whole machine: the feeding mechanism transports the coil to the folding device 2 under the drive of the traction roller group. The folding device 2 folds the two sides of the coil, that is, processes the folding edge of the three-dimensional bag mouth, which is convenient for pasting tape and thickening the bag mouth size, preventing rupture, and also beautifying the bag mouth; then the automatic tape-breaking gluing device 3 automatically glues and cuts the tape; the handle pressing device 4 sticks the handle to the glued coil to complete the handle pressing work; the coil then passes through the reciprocating lifting mechanism 5, the indentation device 6, and the punching device 7 in sequence, among which the reciprocating lifting mechanism 5 According to the actual situation, it automatically moves up or down to adjust the coil material to ensure that the coil material spacing between two adjacent sets of punching holes of the punching device 7 is an integer multiple of the width or length of the three-dimensional bag (this size varies according to the specification type of the three-dimensional bag), thereby realizing the processing of three-dimensional bags of different specifications and types without manual adjustment; and then the labeling mechanism 9 performs center positioning on the three-dimensional bag, which is convenient for the subsequent bag forming device 8 and the bag folding device 10 to process the coil material and process the shape, edge sealing, and inserting of the three-dimensional bag; finally, the bag sorting mechanism 11 is used to collect and organize the three-dimensional bag.

[0058] The above specific embodiment has the following advantages:

[0059] 1. A reciprocating lifting mechanism 5 is provided to ensure that the spacing of materials in the punching, cutting and other processes is an integer multiple of the spacing of the three-dimensional bags to be processed, and automatically adjusts according to different specifications and types of three-dimensional bags;
