Description

Technical Field

[0001] This utility model relates to the field of welding electrode packaging technology, specifically to an automatic boxing machine for welding electrode production. Background Technology

[0002] In the large-scale production of welding electrodes, automatic boxing machines are key equipment for efficiently transferring welding electrodes from the production line to finished product packaging boxes. Their operational stability directly affects the production efficiency and product qualification rate of the entire production line.

[0003] Existing automatic welding rod boxing machines typically include core components such as a box feeding mechanism, a box suction mechanism, a limiting component, and a boxing execution mechanism. In actual production, the box suction mechanism often fails to fully open the packaging box due to insufficient negative pressure or wear on the suction cups. In this case, the incompletely opened box is still conveyed to the limited range of the limiting component. However, since the limiting component in existing technology is a fixed structure with adjustable spacing, it is difficult for operators to remove the incomplete box. To solve this jamming problem, operators must stop the machine and manually disassemble or lift the limiting component to remove the incomplete box. This not only causes prolonged production line interruptions, severely impacting production efficiency, but also prevents the box from being limited on the top surface, causing it to shift. Furthermore, frequent shutdowns and manual operations increase the box breakage rate, leading to raw material waste and hindering production cost control. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this utility model provide an automatic boxing machine for welding electrode production, which solves the technical problem in the prior art where the packaging box cannot be removed because the limiting component cannot move when the suction mechanism fails to open the packaging box.

[0042] The beneficial effects of this utility model are as follows:

[0043] In this invention, during the automated boxing process of large-scale welding electrode production, existing equipment, due to a malfunction in the suction mechanism causing the packaging box to not fully open, suffers from a stuck box that is difficult to remove. Workers must stop the machine to disassemble the limiting component, causing prolonged production line interruptions, a sharp drop in production efficiency, and increased raw material costs due to manual operation. Frequent downtime also exacerbates equipment wear and tear. This invention's automated boxing machine for welding electrode production addresses this issue by incorporating an adjustable lifting limiting plate within the limiting component. Specifically, when a box becomes stuck, there is no need to stop the machine to disassemble the limiting component; simply adjusting the lifting limiting plate allows the unopened box to be removed, shortening troubleshooting time. Furthermore, the lifting limiting plate is positioned at the same horizontal level as the welding electrode inlet and provides top-level restraint to the packaging box located at the electrode insertion point, ensuring the box is aligned with the inlet pipe and improving the efficiency of welding electrode boxing.

[0060] The automatic boxing machine for welding electrode production is a piece of equipment in the later packaging stage of the welding electrode production line. It is mainly used to automatically pack the formed and dried finished welding electrodes into packaging boxes 100 according to preset specifications, such as a certain quantity and a pre-set arrangement. The packaging boxes 100 can be cardboard boxes or plastic boxes, etc., and then seal them, replacing traditional manual boxing. Its core value lies in improving efficiency and ensuring boxing accuracy. It should be noted that after the welding electrodes are sorted by the sorting machine, they are conveyed to the feed pipe 11 of the automatic boxing machine to begin the boxing operation.

[0061] like Figures 1-8 As shown, an automatic boxing machine for welding rod production is provided in one embodiment of the present invention. It is used to automatically load welding rods into packaging boxes 100. The machine includes a frame 1, a conveying mechanism 2, and a limiting component 3. Specifically, a feeding pipe 11 for conveying welding rods is provided on the side wall of the frame 1. After the welding rods are sorted by the previous sorting machine, the outlet 102 of the sorting machine is connected to the feeding pipe 11 of the boxing device, so that the sorted welding rods can be pushed into the feeding pipe 11 by the push plate on the sorting machine. The conveying mechanism 2 is arranged along the length of the frame 1. The conveying mechanism 2 can convey the packaging box 100 to the aligned feeding channel, so that the welding rods can smoothly enter the packaging box 100. Then the conveying mechanism 2 continues to convey the packaging box 100 containing the welding rods to the sealing mechanism 4. The limiting component 3 is arranged on the frame 1 and located above the conveying mechanism 2.

[0062] Furthermore, the limiting component 3 includes a mounting frame 31 and a lifting limiting plate 32. The mounting frame 31 is mounted on the frame 1 and located above the conveying mechanism 2. The lifting limiting plate 32 is mounted on the mounting frame 31 and can descend. After the packaging box 100 is aligned with the feeding pipe 11, the lifting limiting plate 32 can press against the top surface of the packaging box 100 to limit and fix the packaging box 100. The lifting limiting plate 32 is a square plate with a rod connected to its top surface. The rod is connected to the movable end of the driving component. The driving component drives the rod to descend, and the rod drives the lifting limiting plate 32 to descend, so that the lifting limiting plate 32 presses against the top surface of the packaging box 100. The lifting limiting plate 32 only contacts and presses against the packaging box 100 without squeezing it, preventing the packaging box 100 from being squeezed and deformed, which would prevent the welding rod from being inserted.

[0063] Specifically, the conveying mechanism 2 conveys the packaging box 100 along the length of the frame 1. When the packaging box 100 moves to a position aligned with the feeding pipe 11, the lifting limit plate 32 moves downward along the mounting frame 31 and presses against the top surface of the packaging box 100 to limit and fix the packaging box 100, ensuring that the welding rod accurately enters the packaging box 100 through the feeding pipe 11. When the suction mechanism 5 fails to open the packaging box 100 and the packaging box 100 needs to be removed, the lifting limit plate 32 moves upward along the mounting frame 31 to release the pressure on the top surface of the packaging box 100, and the operator can directly remove the packaging box 100.

[0064] It should be noted that the lifting limit plate 32 is mounted on the conveying mechanism 2 via the mounting bracket 31. The lifting limit plate 32 can be raised and lowered relative to the mounting bracket 31. Compared with the fixed structure limit component 3 in the prior art, when the packaging box 100 is not opened, the limit can be released simply by moving the lifting limit plate 32 upward. There is no need to stop the machine to disassemble or lift the limit component 3, thus avoiding long-term interruption of the production line and improving production efficiency. At the same time, there is no need to manually disassemble the limit component 3, which reduces the damage to the packaging box 100 during the removal process, reduces raw material waste, and controls production costs.

[0065] For example, such as Figure 2 As shown, in some examples, the limiting component 3 also includes a mounting rod 33 and a limiting frame 34. The mounting rod 33 is disposed on the frame 1; the limiting frame 34 is disposed on the mounting rod 33 and extends along the conveying direction of the conveying mechanism 2. The limiting frame 34 is used to limit the packaging box 100 located on the conveying mechanism 2 in the vertical direction.

[0066] Specifically, during the conveying process of the packaging box 100, the limiting frame 34 is fixed to the frame 1 by the mounting rod 33, forming a vertical limit on the packaging box 100 along the conveying direction, preventing the packaging box 100 from bouncing upwards during the conveying process, and achieving stable conveying of the packaging box 100 throughout the entire conveying process; when the packaging box 100 is aligned with the feeding pipe 11, the lifting limiting plate 32 presses down against the top surface of the packaging box 100, and the limiting frame 34 and the lifting limiting plate 32 together achieve bidirectional vertical limitation of the packaging box 100; when the packaging box 100 is not opened and needs to be taken out, the lifting limiting plate 32 moves upward, and since the limiting frame 34 only acts in the vertical direction, it does not affect the operator from taking out the packaging box 100 from the horizontal direction.

[0067] It should be noted that the limiting frame 34 extends along the conveying direction and is fixed by the mounting rod 33, which not only enhances the vertical limiting stability of the packaging box 100, but also does not obstruct the conveying mechanism 2 from conveying the packaging box 100. At the same time, compared with the completely fixed limiting component 3 in the prior art, this application can remove the box simply by raising the lifting limiting plate 32 when the packaging box 100 is not opened. The limiting frame 34 does not form an obstacle to removing the box, further ensuring production continuity and improving the reliability and ease of operation of the limiting.

[0068] For example, such as Figure 3 , Figure 4 , Figure 5 as well as Figure 6 As shown, in some examples, the packaging box 100 has two small flaps and two large flaps. Two sets of sealing mechanisms 4 are provided on the two side walls of the frame 1. The two sets of sealing mechanisms 4 are respectively provided on both sides of the frame 1 and seal the flaps at both ends of the packaging box 100. It can be understood that one end of the packaging box 100 has two small flaps and two large flaps.

[0069] Specifically, the sealing mechanism 4 includes an automatic sealing component 41, a sealing plate 42, a guide plate 43, and a pressing rod 44. The automatic sealing component 41 is oscillatingly mounted on the frame 1 and located near the box inlet 201 of the conveying mechanism 2. The automatic sealing component 41 can oscillate horizontally in the conveying direction of the conveying mechanism 2. When the packaging box 100 is filled with welding rods, it is conveyed to the automatic sealing component 41 by the conveying mechanism 2. The automatic sealing component 41 oscillates to contact and push the first small flap 1001 to fold against the packaging box 100. The sealing plate 42 is mounted on the frame 1. When the packaging box 100 moves to the area of ​​the sealing plate 42 with the conveying mechanism 2, the sealing plate 42 can contact and push the second small flap 1002 to fold.

[0070] Next, guide plate 43 is mounted on frame 1. The inclined surface 431 of guide plate 43 slopes downward from the end away from sealing plate 42 to the end closer to sealing plate 42. When packaging box 100 moves with conveying mechanism 2, it contacts inclined surface 431. Inclined surface 431 can push against first large fold 1003, causing first large fold 1003 to fold. Pressing rod 44 is oscillatingly mounted on frame 1. Pressing rod 44 can swing vertically and push second large fold 1004, folding and pressing second large fold 1004 against first large fold 1003. Glue gun is mounted between guide plate 43 and pressing rod 44. Glue gun is used to spray glue onto first large fold 1003. The automatic sealing component 41, sealing plate 42, guide plate 43, and pressing rod 44 are arranged sequentially along the conveying direction of conveying mechanism 2.

[0071] It should be noted that, according to the folding type of the packaging box 100, the components of the sealing mechanism 4 are arranged sequentially along the conveying direction. The conveying mechanism 2 drives the movement of the packaging box 100, so that each component completes the folding action of different folds respectively. The glue gun is set between the guide plate 43 and the pressing rod 44 to ensure that glue is sprayed in time after the first large fold 1003 is folded, and then the fold is pressed and glued by the pressing rod 44.

[0072] Specifically, the conveying mechanism 2 drives the packaging box 100 to move along the conveying direction. First, it passes the automatic sealing component 41, which swings horizontally in the conveying direction, contacting and pushing the first small flap 1001 to fold. Then, the packaging box 100 moves to the sealing plate 42, where the side wall of the packaging box 100 contacts the sealing plate 42, and the sealing plate 42 pushes the second small flap 1002 to fold. Subsequently, the packaging box 100 moves to the guide plate 43, where the bottom of the packaging box 100 contacts the inclined surface 43 of the guide plate 43. 1. The inclined surface 431 pushes the first large fold 1003 to fold, and then the packaging box 100 on the conveyor chain 21 is conveyed to the glue gun position. The glue gun sprays glue onto the side of the first large fold 1003 away from the first small fold 1001 and the second small fold 1002. Finally, the packaging box 100 moves to the pressing rod 44, the pressing rod 44 swings vertically, pushes the second large fold 1004 to fold and press it against the side of the first large fold 1003 coated with glue, and the packaging box 100 is sealed.

[0073] The automatic sealing component 41, sealing plate 42, guide plate 43, and pressing rod 44 are arranged sequentially along the conveying direction and are linked with the movement of the conveying mechanism 2. No additional driving component is needed to drive the folding of the flaps, simplifying the structure. Each component corresponds to the folding of the first small flap 1001, the second small flap 1002, the first large flap 1003, and the second large flap 1004, with clear division of labor to ensure that the flaps are folded in place. The glue gun is set between the guide plate 43 and the pressing rod 44 so that the glue spraying action follows the folding of the first large flap 1003 and is then pressed by the pressing rod 44 to ensure that the flaps are firmly bonded.

[0074] For example, such as Figure 7 As shown, in some examples, the conveying mechanism 2 includes a conveyor chain 21 and a limiting plate 22; the conveyor chain 21 is cyclically arranged on the frame 1 and is used to convey the packaging box 100; the limiting plate 22 is a plurality of L-shaped plates, which are spaced apart on the conveyor chain 21, and each group of L-shaped plates consists of at least 4 plates. The limiting plate 22 can abut against the side wall of the packaging box 100 so that the packaging box 100 moves with the conveyor chain 21.

[0075] Specifically, the conveyor chain 21 circulates on the frame 1. The box suction mechanism 5 places the packaging box 100 on the conveyor chain 21. The limiting plate 22 on the conveyor chain 21 abuts against the side wall of the packaging box 100. As the conveyor chain 21 moves circulantly, the limiting plate 22 drives the packaging box 100 to move along the length of the frame 1, passing through the limiting component 3 and the sealing mechanism 4 in sequence. The spacing of the limiting plate 22 is adapted to the size of the packaging box 100 to ensure that multiple packaging boxes 100 are conveyed continuously in sequence.

[0076] The continuous conveying of the packaging box 100 is achieved by the cyclical motion of the conveyor chain 21. The spaced limit plates 22 abut against the side wall of the packaging box 100 and drive the packaging box 100 to move synchronously with the conveyor chain 21, thus avoiding the problem of the packaging box 100 shifting or slipping during the conveying process.

[0077] Specifically, the conveyor chain 21 is cyclically arranged to continuously transport the packaging box 100, improving the efficiency of the conveying process. Several limiting plates 22 are spaced apart on the conveyor chain 21, which move the packaging box 100 by abutting against the side wall, preventing the packaging box 100 from shifting during the transport process and ensuring that the packaging box 100 can be accurately aligned with the feed pipe 11 and cooperate with the various components of the sealing mechanism 4. The structure of the limiting plates 22 does not require clamping or fixing the packaging box 100. It is only driven by abutting against the side wall. When the packaging box 100 is not opened, after releasing the lifting limiting plate 32, the packaging box 100 can be directly removed from the conveyor chain 21 without affecting the operation of the conveyor chain 21, further reducing downtime and ensuring production continuity.

[0078] For example, such as Figure 1 and Figure 7 As shown, in some examples, the frame 1 is also provided with a box suction mechanism 5, which includes a support frame 51, a first suction cup 52 and a second suction cup 53; the support frame 51 is provided on the frame 1 and located above the box inlet end 201 of the frame 1; the first suction cup 52 is rotatably provided on the support frame 51, and the first suction cup 52 can suck up the unopened packaging box 100 and drive the packaging box 100 to move so as to place the packaging box 100 on the conveyor chain 21; the second suction cup 53 is provided on the frame 1 and located below the first suction cup 52, and the second suction cup 53 can receive and cooperate with the first suction cup 52 to open the packaging box 100.

[0079] The first suction cup 52 is installed above the box inlet 201 via the support frame 51. The rotation of the first suction cup 52 is used to grasp and transfer the unopened packaging box 100. The second suction cup 53 is set below the first suction cup 52. The cooperation of the two enables the packaging box 100 to be opened, preparing for subsequent conveying and boxing.

[0080] Specifically, the first suction cup 52 rotates around the support frame 51 and moves to the position where the unopened packaging box 100 is stored. After suctioning an unopened packaging box 100, it rotates above the second suction cup 53. The second suction cup 53 supports the packaging box 100 upwards. The first suction cup 52 and the second suction cup 53 apply suction from both sides of the packaging box 100 to open the unopened packaging box 100. After opening, the first suction cup 52 releases suction, and then the second suction cup 53 slides downwards to the box inlet end 201 of the conveyor chain 21. The second suction cup 53 places the packaging box 100 on the conveyor chain 21 and then releases suction. The packaging box 100 is placed on the conveyor chain 21 below and is driven by the conveyor chain 21 into the subsequent process. If it is not fully opened, the packaging box 100 moves with the conveyor mechanism 2 to the limiting component 3 and can be removed by raising and lowering the lifting limiting plate 32.

[0081] It should be noted that the cooperative structure of the first suction cup 52 and the second suction cup 53 can effectively open the packaging box 100, reducing the possibility of it not opening due to insufficient negative pressure or wear of the suction cups; the support frame 51 provides rotational support for the first suction cup 52, ensuring that the first suction cup 52 can grasp and transfer the packaging box 100; the second suction cup 53 is located below the first suction cup 52, forming a coordinated opening structure, which improves the opening efficiency and success rate; at the same time, the suction box mechanism 5 cooperates with the limiting component 3, so that even if there are still unopened packaging boxes 100, they can be easily removed by the lifting limiting plate 32 of the limiting component 3, without disassembling the suction box mechanism 5 or the limiting component 3, further reducing the probability of jamming and improving production efficiency.

[0082] For example, such as Figure 1 and Figure 7 As shown, in some examples, the frame 1 is also provided with a box-up assembly 6, which includes a support frame 61 and a clamping plate 62. The support frame 61 is located on the side of the support frame 51 away from the second suction cup 53. The support frame 61 is provided with a box outlet 6101, which is arranged directly opposite to the first suction cup 52. The clamping plate 62 is slidably disposed above the support frame 61. Specifically, the unopened packaging box 100 is stored through the support frame 61. The box outlet 6101 is directly opposite to the first suction cup 52 to ensure that the first suction cup 52 grasps the center of the packaging box 100, so that the position for subsequent placement into the second suction cup 53 is determined. The clamping plate 62 is disposed above the support frame 61 and presses against the stack of packaging boxes 100 to prevent the packaging boxes 100 from tilting during the grasping process.

[0083] Several unopened packaging boxes 100 are stacked inside the support frame 61, with the clamping plate 62 pressing against the stacked packaging boxes 100. The first suction cup 52 rotates around the support frame 51 to the box outlet 6101 of the support frame 61. Since the box outlet 6101 is directly opposite the first suction cup 52, the first suction cup 52 accurately picks up the unopened packaging box 100 at the top of the stack. After picking it up, the first suction cup 52 rotates above the second suction cup 53 to open it up. As the packaging boxes 100 are picked up continuously, the clamping plate 62 continues to press against the remaining packaging boxes 100 to prevent the remaining packaging boxes 100 on the support frame 61 from falling off.

[0084] The box outlet 6101 of the support frame 61 is arranged directly opposite the first suction cup 52, avoiding the problem of positional deviation when the first suction cup 52 grasps the box and improving the grasping accuracy. The clamping plate 62 presses against the stacked packaging boxes 100 to prevent the packaging boxes 100 from tilting and causing grasping failure. The cooperation between the box loading component 6 and the box suction mechanism 5 makes the loading and grasping of the packaging boxes 100 a continuous process, eliminating the need for manual placement of each packaging box 100, reducing manual intervention and improving loading efficiency. At the same time, the structure is stable, reducing the situation of not opening due to loading deviation, and further ensuring the smoothness of subsequent processes.

[0085] For example, such as Figure 1 , Figure 7 and Figure 8 As shown, in some examples, the feeding pipe 11 is located between the second suction cup 53 and the automatic sealing component 41. The feeding pipe 11 has an inlet 101 and an outlet 102. Specifically, after the second suction cup 53 and the first suction cup 52 cooperate to open the packaging box 100, the conveyor chain 21 drives the packaging box 100 from the second suction cup 53 to the position directly opposite the feeding pipe 11. When the opening 1100 of the packaging box 100 is aligned with the outlet 102 of the feeding pipe 11, the external welding rod enters the feeding pipe 11 through the inlet 101 and then falls into the packaging box 100 through the outlet 102. After the box is filled, the conveyor mechanism 2 continues to drive the packaging box 100 to move toward the automatic sealing component 41 to enter the sealing process.

[0086] The feeding pipe 11 is located between the second suction cup 53 and the automatic sealing component 41, which makes the "opening-packing-sealing" process seamlessly connected, reduces the conveying distance between processes, and improves the overall production efficiency. The feeding port 101 receives the welding rod, and the structure of the discharge port 102 and the opening 1100 of the packaging box 100 are aligned to ensure that the welding rod can accurately enter the packaging box 100, avoiding the waste caused by the welding rod falling and the problem of equipment jamming.

[0087] For example, such as Figure 2 and Figure 8As shown, in some examples, a driver 7 is provided on the frame 1. The power output end of the driver 7 is connected to the feed pipe 11. The driver 7 can drive the feed pipe 11 to slide towards the opening 1100 of the packaging box 100, so that the discharge port 102 is opened and connected to the opening 1100. By providing sliding power to the feed pipe 11 through the driver 7, the feed pipe 11 can move towards the opening 1100 of the packaging box 100. The structure of the discharge port 102 is used to help open the opening 1100, and at the same time, the discharge port 102 and the opening 1100 are accurately connected.

[0088] Specifically, the conveying mechanism 2 moves the packaging box 100 to below the feeding pipe 11. When the four flaps of the packaging box 100 are not fully opened, the driver 7 drives the feeding pipe 11 to slide towards the opening 1100 of the packaging box 100. The outlet 102 of the feeding pipe 11 contacts the edge of the opening 1100 of the packaging box 100, and the opening 1100 is further opened with the sliding action. When the outlet 102 fully opens the opening 1100 and connects with the opening 1100, the driver 7 stops driving, and the welding rod enters the packaging box 100 through the inlet 101 and the outlet 102. After the box is packed, the driver 7 drives the feeding pipe 11 to slide away from the packaging box 100 to avoid the packaging box 100, so that the conveying mechanism 2 can carry the packaging box 100 into the subsequent process.

[0089] The structure of the drive 7 driving the feeding pipe 11 to slide allows the feeding pipe 11 to have the dual functions of "conveying welding rods" and "assisting in opening the opening 1100". For packaging boxes 100 that are not fully opened by the suction mechanism 5, the sliding action of the discharge port 102 can further open them, reducing the number of unopened packaging boxes 100 and reducing the frequency of box picking. At the same time, the discharge port 102 is precisely connected to the opening 1100 through sliding, avoiding manual adjustment and alignment, improving the accuracy of boxing, reducing the problem of device jamming, and further improving production efficiency and boxing quality.

[0090] It should be noted that both the inlet 101 and outlet 102 of the material reducing pipe are provided with outwardly expanding plates. The outwardly expanding plate of the inlet 101 can ensure that the welding rod is smoothly pushed into the inlet pipe 11, and the outwardly expanding plate of the outlet 102 can ensure that the opening 1100 of the packaging box 100 is opened so that the welding rod can smoothly enter the packaging box 100.

[0091] For example, such as Figure 3 and Figure 4As shown, in some examples, the automatic sealing component 41 is used to fold the first small flap 1001 on the packaging box 100. The automatic sealing component 41 includes a fixed base 411, a paddle 412, and a telescopic device 413. The fixed base 411 is disposed on the frame 1. The paddle 412 is rotatably disposed on the fixed base 411. The telescopic device 413 is disposed on the fixed base 411. The movable end of the telescopic device 413 is hinged to the paddle 412. The telescopic device 413 can drive the paddle 412 to swing.

[0092] The mounting base 411 provides mounting support for the lever 412 and the telescopic device 413. The movable end of the telescopic device 413 is hinged to the lever 412. The telescopic movement of the telescopic device 413 is converted into the swinging movement of the lever 412 to realize the folding of the first small fold 1001, ensuring the controllability and stability of the folding action.

[0093] Specifically, when the conveyor chain 21 moves the packaging box 100 to the automatic sealing component 41, the movable end of the telescopic device 413 extends, pushing the lever 412 to rotate around the fixed base 411. The lever 412 swings horizontally in the conveying direction of the conveying mechanism 2. During the swing, the lever 412 contacts the first small fold 1001 of the packaging box 100, and pushes the first small fold 1001 to fold inward to the packaging box 100 with the swing action. After the folding is completed, the movable end of the telescopic device 413 retracts, driving the lever 412 to reset and avoid the subsequent movement of the packaging box 100.

[0094] The hinged structure of the telescopic device 413 and the lever 412 allows the swing amplitude of the lever 412 to be adjusted by controlling the telescopic amount of the telescopic device 413, ensuring that the first small fold 1001 is folded in place and avoiding the problem of the sealing process being unable to continue due to incomplete folding. Compared with manual folding or cam-driven folding, this structure has a rapid response and a high degree of matching with the movement rhythm of the conveying mechanism 2, improving the folding efficiency and quality of the first small fold 1001. At the same time, this structure works in conjunction with other components of the sealing mechanism 4 to ensure the smooth folding of the subsequent second small fold 1002 and the large fold, further guaranteeing the sealing quality.

[0095] For example, such as Figure 5As shown, in some examples, a support base 12 is also provided on the frame 1, and the clamping rod 44 is rotatably mounted on the support base 12; an electric actuator 13 is mounted on the support base 12; one end of a rack 14 is mounted on the movable end of the electric actuator 13; a gear 15 meshes with the other end of the rack 14; wherein, the gear 15 is fixedly connected to the hinge shaft 440 of the clamping rod 44 and the support base 12, the electric actuator 13 drives the rack 14 to slide, and the rack 14 can drive the gear 15 to rotate, so that the clamping rod 44 swings. By using the electric actuator 13 to drive the rack 14 to slide, the meshing of the rack 14 and the gear 15 converts linear motion into rotational motion, and the gear 15 drives the hinge shaft 440 of the clamping rod 44 to rotate, realizing the vertical swing of the clamping rod 44 and ensuring the swing angle of the clamping rod 44.

[0096] Specifically, when the conveying mechanism 2 moves the packaging box 100 to below the pressing rod 44, the movable end of the electric push rod 13 extends, pushing the rack 14 to slide horizontally. During the sliding process of the rack 14, it drives the meshing gear 15 to rotate. The gear 15 is fixed to the hinge shaft 440 of the pressing rod 44, so the rotation of the gear 15 drives the pressing rod 44 to swing vertically downward around the support base 12. During the swinging process, the pressing rod 44 contacts the second large fold 1004 of the packaging box 100, pushes the second large fold 1004 to fold towards the first large fold 1003, and presses the second large fold 1004 onto the first large fold 1003 after it has been glued. After pressing is completed, the movable end of the electric push rod 13 retracts, drives the rack 14 to slide in the opposite direction, the rack 14 drives the gear 15 to rotate in the opposite direction, and the pressing rod 44 swings vertically upward to reset, avoiding the subsequent packaging box 100.

[0097] The transmission structure of the electric actuator 13, rack 14, and gear 15 can control the swing angle and clamping force of the clamping rod 44, avoiding insufficient force leading to weak fold adhesion, or excessive force leading to damage to the packaging box 100. The fixed connection between the gear 15 and the hinge shaft 440 of the clamping rod 44 ensures high transmission efficiency, no slippage, and improved action stability. In conjunction with the glue gun and guide plate 43, the second large fold 1004 is pressed in time after the first large fold 1003 is glued, ensuring the adhesion effect, improving the sealing firmness, and further improving sealing efficiency and pass rate.

[0098] It should be noted that after the packaging box 100 is sealed, the sealed packaging box 100 is conveyed to the subsequent conveyor belt. The conveyor belt is equipped with pressing components on both sides. The pressing components can slide relative to each other to press the two ends of the packaging box 100, so that the glue on the first large fold 1003 and the second large fold 1004 fix and seal the opening 1100 of the packaging box 100.
