Description

Technical Field

[0001] The invention relates to the field of automation equipment, and in particular to an automatic bag sealing and labeling device for hexagonal paper bags. Background Art

[0002] Hexagonal paper bags are common packaging paper bags on the market. After packaging the products, they usually need to be sealed. At present, the packaging method of hexagonal paper bags is still in the traditional manual packaging, sealing and labeling. The process is generally to fold the bag mouth at a certain distance from the bag mouth, and then stick the bag mouth with a label. This manual packaging method has low packaging efficiency and is not conducive to batch packaging of products. On the other hand, hexagonal paper bags are mostly used for food packaging, and manual packaging will also affect the hygiene of food. Summary of the invention

[0003] In view of this, the present invention provides an automatic bag sealing and labeling device which can realize the full automation of the folding and sealing process of hexagonal paper bags.

[0004] The purpose of the present invention is achieved through the following technical solutions: A device for automatically sealing and labeling hexagonal paper bags comprises: a frame, a conveyor belt, a gathering mechanism, a folding mechanism and a labeling mechanism; the conveyor belt is passed through the frame and is used to convey the hexagonal paper bags; the gathering mechanism is arranged on the frame and is located above the conveyor belt, and is used to gather two opposite sides of the hexagonal paper bags; the folding mechanism comprises a bag pressing component and a bending component movably arranged on the frame, the bag pressing component and the bending component are arranged opposite to each other and are respectively located on the other two opposite sides of the hexagonal paper bags, the bag pressing component is used to press the hexagonal paper bags and form creases, and the bending component is used to fold the bag opening of the hexagonal paper bags along the creases; the labeling mechanism is movably arranged on the frame and is used to label the folded bag opening of the hexagonal paper bags.

[0005] In the above technical solution, the conveyor belt uses intermittent transmission to transport the hexagonal paper bag to a preset workstation. At this time, the two opposite sides of the hexagonal paper bag are completely retracted through the folding mechanism to prevent the paper bag from undergoing unnecessary deformation during the subsequent folding process, thereby affecting the aesthetics and integrity of the product or causing product damage. After completing the retraction process, the hexagonal paper bag is pressed and fixed by a bag pressing assembly to form a crease, which is located below the opening of the hexagonal paper bag. The hexagonal paper bag is then folded along the crease by a bending assembly, and finally the bag opening of the hexagonal paper bag is labeled and fixed by a labeling mechanism.

[0006] Therefore, the above-mentioned device realizes the automation of the whole process of hexagonal paper bags from conveying, gathering, folding to labeling through an integrated design, thereby significantly improving production efficiency, reducing dependence on manual operation, and reducing labor costs. At the same time, it can also effectively avoid operators from contacting the hexagonal paper bags for a long time, ensuring the cleanliness and hygiene of the hexagonal paper bags.

[0007] Optionally, in a possible implementation, the bag pressing assembly includes a first driving member arranged on the frame, and a pressing plate arranged at an output end of the first driving member, and the first driving member is used to drive the pressing plate to approach or move away from the hexagonal paper bag.

[0008] In the above technical solution, the first driving member can make the pressing plate quickly and stably approach or move away from the hexagonal paper bag, and cooperate with the bending component to fix the hexagonal paper bag to facilitate subsequent folding operations, and can achieve precise pressing of the hexagonal paper bag, thereby helping to maintain the integrity and shape consistency of the paper bag and improve the overall quality of the product.

[0009] Optionally, in a possible implementation, a guide member is provided on the frame, the bag pressing assemblies are divided into two groups, the bag pressing assemblies are movably arranged on the guide member via a connecting member, and the two bag pressing assemblies can be moved closer to or farther away from each other.

[0010] In the above technical solution, by arranging a guide on the frame and allowing the bag pressing assembly to move on the guide through the connecting piece, the two bag pressing assemblies can be flexibly moved closer to or farther from each other. This design provides great flexibility and can quickly adjust the distance between the bag pressing assemblies according to hexagonal paper bags of different sizes or shapes, thereby ensuring the accuracy and consistency of the pressing effect.

[0011] Optionally, in a possible implementation, the bending assembly includes a second driving member arranged on the frame, a pad plate arranged at the output end of the second driving member and opposite to the pressure plate, a clamping plate rotatably mounted on the pad plate, and a flipping driving member for driving the clamping plate to rotate, and the second driving member is used to drive the pad plate to approach or move away from the hexagonal paper bag.

[0012] In the above technical solution, the setting of the second driving member enables the pad to accurately approach or move away from the hexagonal paper bag, and the relative position between the pad and the pressure plate is accurate, so as to better cooperate to clamp the hexagonal paper bag. When the hexagonal paper bag is clamped, an indentation is formed on the top edge of the pressure plate. At this time, the flipping driving member can realize the folding of the bag mouth of the hexagonal paper bag by driving the clamping plate to flip, which can effectively improve the consistency and stability of the folding of the hexagonal paper bag.

[0013] Optionally, in a possible implementation, the clamping plates are two plates spaced apart from each other, a clearance opening is formed between the two clamping plates, and the clearance opening may be opposite to the labeling mechanism.

[0014] In the above technical solution, the design of the avoidance opening enables the labeling mechanism to be more accurately positioned at the position where labeling is required during operation, avoiding the blocking or interference of the clamping plate itself on the labeling path, thereby improving the accuracy and consistency of labeling. In addition, through the setting of the avoidance opening, the labeling mechanism can directly and unobstructedly contact the area to be labeled, simplifying the steps in the labeling process, reducing the time waste caused by adjusting the position or angle, and improving production efficiency.

[0015] Optionally, in a possible implementation, an electromagnet is provided on the clamping plate, and the electromagnet can be adsorbed on the pad.

[0016] In the above technical solution, the magnetic force generated between the electromagnet and the pad after being energized can provide the force to fold and fix the hexagonal paper bag, while ensuring that sufficient force can be provided for folding, the high power requirement of the flipping drive component is reduced. In this way, the flipping drive component only needs to provide the power for the splint to perform circular motion, and does not need to provide the clamping force for pressing the bag mouth of the hexagonal paper bag to fold, thereby further reducing the cost.

[0017] Optionally, in a possible implementation, the folding mechanism includes a fixed plate and a folding drive member provided on the frame, and two clips rotatably mounted on the fixed plate and spaced apart, and the folding drive member is used to drive the two clips to rotate synchronously and in opposite directions.

[0018] In the above technical solution, through the precise control of the folding drive, the two clips can rotate synchronously and in opposite directions, so as to realize the rapid and accurate folding of the hexagonal paper bag. Among them, the fixing plate provides a stable support for the clips, ensures the stability of the clips during the rotation process, and avoids operational errors caused by shaking or misalignment. In addition, the folding mechanism can adjust the spacing and rotation angle of the clips according to the shape and size of different items, and has strong adaptability.

[0019] Optionally, in a possible implementation, the folding drive member includes a folding cylinder disposed on the frame, a connecting plate disposed on the output shaft of the folding cylinder, and two cranks rotatably mounted on the connecting plate, and the two cranks are rotatably connected to the two clips respectively.

[0020] In the above technical solution, the folding cylinder is located between the two clamps. When the folding cylinder drives the connecting plate to rise and fall, it will simultaneously drive the crank and the clamp to rotate, thereby realizing the synchronous relative flipping of the two clamps. In addition, by adjusting the length or position of the crank, the folding angle and clamping force of the clamp can be easily adjusted to meet the clamping or folding requirements of different objects.

[0021] Optionally, in a possible implementation, the crank is rotatably connected to the clip via an extension block, the extension block is rotatably mounted on the fixed plate, one end of the extension block is fixedly connected to the clip, and the other end is rotatably connected to the crank.

[0022] In the above technical solution, the design of the extension block makes the connection between the crank and the clip more stable, reduces the stress concentration and wear caused by the direct connection, and improves the stability and durability of the entire folding mechanism. As an intermediate transmission component, the extension block can effectively convert the rotational motion of the crank into the opening and closing motion of the clip, while reducing the energy loss in the power transmission process and improving efficiency. In addition, the design of the extension block also facilitates the connection and disassembly between the clip and the crank.

[0023] Optionally, in a possible implementation, the labeling mechanism includes a vertical driving member arranged on the frame, a horizontal driving member arranged at an output end of the vertical driving member, and a labeling machine arranged at the output end of the horizontal driving member.

[0024] In the above technical solution, the combination of the vertical drive and the horizontal drive enables the labeling machine to move and position accurately in three-dimensional space, meeting the labeling needs in various complex scenes, improving the flexibility and accuracy of the operation. It can also enable the labeling machine to reach the target position quickly and accurately, realize rapid labeling, and greatly improve production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0035] Please refer to Figure 1 and Figure 6The present embodiment provides an automatic sealing and labeling device for hexagonal paper bags 8, comprising: a frame 1, a conveyor belt 2, a gathering mechanism 3, a folding mechanism and a labeling mechanism 6; the conveyor belt 2 is arranged on the frame 1, that is, the conveyor belt 2 passes through the frame 1, and is used to convey the hexagonal paper bags 8, so that the hexagonal paper bags 8 enter the frame 1 from the outside and are sent out after processing; the gathering mechanism 3 is arranged on the frame 1 and is located above the conveyor belt 2, and is used to gather two opposite sides of the hexagonal paper bags 8, generally, mainly used to gather two sides of the hexagonal paper bags 8 in the length direction of the bag mouth side; the folding mechanism includes a bag pressing component 4 and a bending component 5 movably arranged on the frame 1, the bag pressing component 4 and the bending component 5 are arranged opposite to each other and are respectively located on the other two sides opposite to the hexagonal paper bag 8, which are also the two sides in the width direction of the bag opening of the hexagonal paper bag 8, the pressing component is used to press the hexagonal paper bag 8 and form a crease, the crease is located at a distance below the bag opening of the hexagonal paper bag 8, and the bending component 5 is used to fold the bag opening of the hexagonal paper bag 8 along the crease; the labeling mechanism 6 is movably arranged on the frame 1, and is used for labeling the folded bag opening of the hexagonal paper bag 8.

[0036] The conveyor belt 2 of this embodiment uses an intermittent conveying method to convey the hexagonal paper bag 8 to the preset workstation. At this time, the two opposite sides of the hexagonal paper bag 8 are completely retracted through the folding mechanism 3 to prevent the paper bag from undergoing unnecessary deformation during the subsequent folding process, thereby affecting the aesthetics and integrity of the product or causing product damage. After completing the retracting process, the hexagonal paper bag 8 is pressed and fixed by the bag pressing component 4 to form a crease, which is located below the opening of the hexagonal paper bag 8. The hexagonal paper bag 8 is then folded along the crease by the bending component 5, and finally the bag opening of the hexagonal paper bag 8 is labeled and fixed by the labeling mechanism 6.

[0037] Therefore, the device of this embodiment realizes the automation of the whole process of conveying, collecting, folding and labeling of the hexagonal paper bag 8 through an integrated design, thereby significantly improving production efficiency, reducing dependence on manual operation, and reducing labor costs. At the same time, it can also effectively avoid the operator's contact with the hexagonal paper bag 8 for a long time, ensuring the cleanliness and hygiene of the hexagonal paper bag 8.

[0038] Please refer to Figure 1 and Figure 2In this embodiment, the bag pressing assembly 4 includes a first driving member 41 arranged on the frame 1, and a pressing plate 42 arranged at the output end of the first driving member 41, and the first driving member 41 is used to drive the pressing plate 42 to approach or move away from the hexagonal paper bag 8. Among them, the first driving member 41 is a cylinder, and the output shaft of the cylinder is fixedly connected to the pressing plate 42. A mounting seat is provided on the pressing plate 42, and a mounting hole matching the output shaft of the cylinder is provided on the mounting seat, that is, the output shaft of the cylinder is clamped in the mounting hole, and the position of the mounting seat can be set at any position on the pressing plate 42 according to actual needs. It should be noted that the upper edge of the pressing plate 42 is a distance away from the bag mouth of the hexagonal paper bag 8, and the upper edge can press out the fold of the hexagonal paper bag 8.

[0039] The first driving member 41 of this embodiment can make the pressing plate 42 quickly and stably approach or move away from the hexagonal paper bag 8, and cooperate with the bending component 5 to fix the hexagonal paper bag 8 to facilitate subsequent folding operations, and can achieve precise pressing of the hexagonal paper bag 8, thereby helping to maintain the integrity and shape consistency of the paper bag and improve the overall quality of the product.

[0040] Please continue to refer to Figure 1 and Figure 2 In this embodiment, a guide member 7 is provided on the frame 1, and the bag pressing assemblies 4 are divided into two groups. The bag pressing assemblies 4 are movably arranged on the guide member 7 through a connecting member 71, and the two bag pressing assemblies 4 can be close to or away from each other. The two bag pressing assemblies 4 are arranged at intervals along the conveying direction of the conveyor belt 2, and the labeling mechanism 6 can be placed between the two bag pressing assemblies 4. Specifically, the guide member 7 can be two parallel linear modules, and the two bag pressing assemblies 4 can be connected to the output ends of the two linear modules respectively, so that the position between the two bag pressing assemblies 4 can be automatically adjusted. Of course, the guide member 7 can also be a screw rotatably mounted on the frame 1, and the screw can be driven to rotate by a motor. The screw has two threaded sections with opposite rotation directions. The two connecting members 71 are respectively threadedly connected to the two threaded sections. When the screw rotates, the two bag pressing assemblies 4 can move toward or away from each other.

[0041] In this embodiment, the guide member 7 is provided on the frame 1, and the bag pressing assembly 4 is allowed to move on the guide member 7 through the connecting member 71, so that the two bag pressing assemblies 4 can be flexibly moved closer to or farther from each other. This design provides great flexibility, and the distance between the bag pressing assemblies 4 can be quickly adjusted according to hexagonal paper bags 8 of different sizes or shapes, thereby ensuring the accuracy and consistency of the pressing effect, that is, it has a wider range of applications.

[0042] Please refer to Figure 1 , Figure 3 and Figure 4In this embodiment, the bending assembly 5 includes a second driving member 51 arranged on the frame 1, a pad 52 arranged at the output end of the second driving member 51 and opposite to the pressing plate 42, a clamping plate 53 rotatably mounted on the pad 52, and a flipping driving member 54 for driving the clamping plate 53 to rotate. The second driving member 51 is used to drive the pad 52 to approach or move away from the hexagonal paper bag 8. Specifically, the clamping plate 53 is mounted on the upper end of the pad 52 through a hinge shaft, and the flipping driving member 54 drives the clamping plate 53 to flip by driving the hinge shaft to rotate. Before the hexagonal paper bag 8 is folded, the clamping plate 53 and the pad 52 are in a straight state of 180 degrees, and the bag mouth of the hexagonal paper bag 8 is located on the clamping plate 53. When the clamping plate 53 is flipped, the pressing plate 42 fixes and limits the hexagonal paper bag 8, and the clamping plate 53 flips around the upper edge of the pressing plate 42 and drives the folding of the hexagonal paper bag 8 at the same time. Among them, the second driving member 51 is a cylinder, and the flipping driving member 54 is a motor.

[0043] The second driving member 51 of the present embodiment is provided so that the pad 52 can be accurately moved close to or away from the hexagonal paper bag 8, and the relative position between the pad 52 and the pressing plate 42 is accurate, so that the hexagonal paper bag 8 can be better matched to be clamped. When the hexagonal paper bag 8 is clamped, an indentation is formed on the top edge of the pressing plate 42. At this time, the flipping driving member 54 can realize the folding of the bag mouth of the hexagonal paper bag 8 by driving the clamping plate 53 to flip, thereby effectively improving the consistency and stability of the folding of the hexagonal paper bag 8.

[0044] It is worth noting that when the mouth of the hexagonal paper bag 8 is folded, the pressing plate 42 and the pad 52 always firmly fix the hexagonal paper bag 8, which can make the hexagonal paper bag 8 more stable during the folding process, thus ensuring that the folded hexagonal paper bag 8 is more beautiful and practical.

[0045] Please refer to Figure 3 In this embodiment, the two clamps 53 are spaced apart, and a clearance opening 55 is formed between the two clamps 53, and the clearance opening 55 can be opposite to the labeling mechanism 6. The clearance opening 55 can be formed by opening a notch in the middle of a clamp 53; or two independent clamps 53 can be spaced apart, and the distance between the two clamps 53 is the clearance opening 55. It should be noted that the parts of the clamps 53 located on both sides of the clearance opening 55 can be opposite to the two pressing plates 42 respectively, and the two pressing plates 42 should be close to the edge of the hexagonal paper bag 8.

[0046] The design of the avoidance opening 55 of this embodiment enables the labeling mechanism 6 to be more accurately positioned at the position where labeling is required during operation, avoiding the blocking or interference of the clamping plate 53 itself on the labeling path, thereby improving the accuracy and consistency of labeling. In addition, through the setting of the avoidance opening 55, the labeling mechanism 6 can directly and unobstructedly contact the area to be labeled, simplifying the steps in the labeling process, reducing the time waste caused by adjusting the position or angle, and improving production efficiency.

[0047] For details, please refer to Figure 4 In this embodiment, two clamping plates 53 are used as an example, wherein the backing plate 52 is a rectangular plate structure, one side of the backing plate 52 is extended with a convex plate for fixing the flip driving member 54, and the two clamping plates 53 are both rotatably mounted on the other side of the backing plate 52. A sleeve is provided on the side of the backing plate 52 for mounting the clamping plate 53, and a rotating shaft is passed through the sleeve, and the two ends of the rotating shaft are respectively fixedly connected to the two clamping plates 53, and the output end of the flip driving member 54 is fixedly connected to one of the clamping plates 53, so that the flip driving member 54 can synchronously drive the flipping of the connected clamping plates 53.

[0048] Please continue to refer to Figure 3 and Figure 4 In this embodiment, an electromagnet 531 is provided on the clamping plate 53, and the electromagnet 531 can be adsorbed on the pad 52. Specifically, the clamping plate 53 is a rectangular structure. After the electromagnet 531 is energized, the magnetic force generated between the electromagnet 531 and the pad 52 can provide the force for folding and fixing the hexagonal paper bag 8. While ensuring that sufficient force can be provided for folding, the high requirement for the power of the flipping drive 54 is reduced. In this way, the flipping drive 54 only needs to provide the clamping plate 53 with the power for its circular motion, and does not need to provide the clamping force for pressing the hexagonal paper bag 8 to fold the bag mouth, thereby further reducing the cost. Therefore, the power required to be provided by the flipping drive 54 is only related to the size of the clamping plate 53 and the material density. Correspondingly, the direct influencing factor of the main size of the clamping plate 53 is the shortest distance between the folding position and the bag mouth. Under the condition of not affecting the capacity of the paper bag, the main size of the clamping plate 53 generally does not exceed 50mm, and the required flipping drive 54, that is, the power of the motor is also reduced accordingly, and the motor can be directly used to drive the clamping plate 53 to rotate.

[0049] Please refer to Figure 5 In this embodiment, the folding mechanism 3 includes a fixed plate 32 and a folding driving member 31 arranged on the frame 1, and two clips 33 rotatably mounted on the fixed plate 32 and spaced apart, and the folding driving member 31 is used to drive the two clips 33 to rotate synchronously and in opposite directions.

[0050] Through the precise control of the folding drive 31, the two clips 33 can rotate synchronously and in opposite directions, so as to realize the rapid and accurate folding of the hexagonal paper bag 8. Among them, the fixing plate 32 provides a stable support for the clips 33, ensuring the stability of the clips 33 during the rotation process, and avoiding operational errors caused by shaking or misalignment. In addition, the folding mechanism 3 can adjust the spacing and rotation angle of the clips 33 according to the shapes and sizes of different items, and has strong adaptability.

[0051] Specifically, the folding driving member 31 includes a folding cylinder 311 disposed on the frame 1, a connecting plate 32 disposed on the output shaft of the folding cylinder 311, and two cranks 313 rotatably mounted on the connecting plate 32, and the two cranks 313 are rotatably connected to two clips 33. The two ends of the crank 313 are rotatably connected to the connecting plate 32 and the clip 33, respectively, and the clip 33 is rotatably connected to the connecting plate 32.

[0052] In this embodiment, the folding cylinder 311 is located between the two clamps 33. When the folding cylinder 311 drives the connecting plate 32 to rise and fall, it will simultaneously drive the crank 313 and the clamp 33 to rotate, thereby realizing the synchronous relative flipping of the two clamps 33. In addition, by adjusting the length or position of the crank 313, the folding angle and clamping force of the clamp 33 can be conveniently adjusted to meet the clamping or folding requirements of different objects.

[0053] Please continue to refer to Figure 5 More specifically, the crank 313 is rotatably connected to the clip 33 through the extension block 34, and the extension block 34 is rotatably mounted on the fixed plate 32, with one end of the extension block 34 being fixedly connected to the clip 33 and the other end being rotatably connected to the crank 313. The middle position of the extension block 34 is rotatably mounted on the connecting plate 32, and its two ends are rotatably connected to the crank 313 and fixedly connected to the clip 33, respectively, so that the removal and replacement of the clip 33 can be greatly facilitated.

[0054] The design of the extension block 34 makes the connection between the crank 313 and the clip 33 more stable, reduces the stress concentration and wear caused by the direct connection, and improves the stability and durability of the entire folding mechanism 3. As an intermediate transmission component, the extension block 34 can effectively convert the rotational motion of the crank 313 into the opening and closing motion of the clip 33, while reducing the energy loss in the power transmission process and improving the efficiency. In addition, the design of the extension block 34 also facilitates the connection and disassembly between the clip 33 and the crank 313.

[0055] Please refer to Figure 1 and Figure 6In this embodiment, the labeling mechanism 6 includes a vertical driving member 61 arranged on the frame 1, a horizontal driving member 62 arranged at the output end of the vertical driving member 61, and a labeling machine 63 arranged at the output end of the horizontal driving member 62. Specifically, the vertical driving member 61 can be a linear module, which is also a linear motor, and the horizontal driving member 62 can be a cylinder, that is, the cylinder can be fixed at the output end of the linear module, and the labeling machine 63 is fixed to the output shaft of the cylinder. It should be noted that in order to improve the stability of the labeling mechanism 6, a mechanism such as a slide rail for supporting the labeling machine 63 can be added to the frame 1. Of course, as another embodiment, the vertical driving member 61 can also be a linear driving mechanism such as a screw transmission mechanism and a cylinder.

[0056] The combination of the vertical drive member 61 and the horizontal drive member 62 in this embodiment enables the labeling machine 63 to move and position accurately in three-dimensional space, meeting the labeling requirements in various complex scenes, improving the flexibility and accuracy of the operation. It can also enable the labeling machine 63 to reach the target position quickly and accurately, realize rapid labeling, and greatly improve production efficiency.

[0057] It should be noted that the labeling machine 63 is a conventional device in the prior art, which generally includes a bottom plate, a material receiving roll and a material discharging roll arranged on the bottom plate, a plurality of guide rollers and a labeling block, and the labeling machine 63 can stick the label on the hexagonal paper bag 8 through the labeling block. More specifically, the film roll is led out from the material discharging roll, wound around the guide roller and the labeling block, and finally introduced into the material receiving roll, wherein the labeling end of the labeling block is close to the bag pressing assembly 4. In addition, the material receiving roll can be used as a traction mechanism of the labeling machine 63, and the traction mechanism can be a mode in which the material receiving roll is directly driven to rotate by a motor, or a mode in which the motor is driven through a gear transmission structure.

[0058] Please refer to Figure 6The bag sealing and labeling process of this embodiment is as follows: the conveyor belt 2 intermittently conveys the hexagonal paper bag 8 packed with products to the preset station on the frame 1, at this time, the folding mechanism 3 moves, and the folding driving member 31 drives the two clamping pieces 33 to fold, so that the two opposite sides of the hexagonal paper bag 8, usually the two sides in the length direction of the hexagonal paper bag 8, are completely retracted to avoid unnecessary deformation in subsequent processes; then the first driving member 41 and the second driving member 51 respectively drive the pressing plate 42 and the pad 52 to approach the hexagonal paper bag 8 on both sides, and press and fix the paper bag, at this time, the two clamping pieces 33 can be evacuated and reset to the initial position. It is worth noting that the two clamping pieces 33 are completely After being folded, its bottom end does not overlap with the top of the pressing plate 42 or the pad 52 to avoid being unable to be pulled out. In addition, the distance between the two pressing plates 42 is narrowed under the action of the guide member 7 and adapted to the size of the hexagonal paper bag 8; then, the flipping drive member 54 drives the flipping of the clamping plate 53 and drives the bag mouth of the hexagonal paper bag 8 to fold along the top edge of the pressing plate 42, and keep it after folding, and the labeling mechanism 6 labels the bag mouth; after labeling is completed, the labeling mechanism 6 first exits and resets, and then the clamping plate 53 opens, and the two pressing plates 42 move away from each other to detach from the hexagonal paper bag 8 and then reset, and at this time the pad 52 is reset synchronously, so that the sealing and labeling of the hexagonal paper bag 8 are completed, and finally the conveyor belt 2 sends it out.
