As used in this utility model specification and the appended claims, the singular forms "a", "an" and "the" are intended to include plural forms unless the context clearly indicates otherwise.

[0036] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0037] See also Figure 1 , an embodiment of the utility model provides a packaging box sealing device, which includes: a sealing mechanism 10; the sealing mechanism 10 includes: a sealing drive assembly 11, a transmission assembly 12 and a cover-striking assembly 13; the transmission assembly 12 includes a first transmission member 121 and a second transmission member 122, the cover-striking assembly 13 includes a first cover-striking member 131 and a second cover-striking member 132, the first transmission member 121 is connected to the first cover-striking member 131, the second transmission member 122 is connected to the second cover-striking member 132, the first transmission member 121 is transmission-connected to the second transmission member 122, the sealing drive assembly 11 is drivingly connected to the first transmission member 121, the first transmission member 121 and the second transmission member 122 can respectively drive the first cover-striking member 131 and the second cover-striking member 132 to open or close.

[0038] In this embodiment, under the drive of the capping drive assembly 11, the first transmission member 121 and the second transmission member 122 can respectively drive the first capping member 131 and the second capping member 132 to open or close, thereby completing the capping action of the packaging box, realizing an automated packaging box capping operation, eliminating the need for complex manual operations, making the capping process more flexible and controllable, and not only significantly improving production efficiency and reducing waste of manpower and material resources, but also effectively avoiding losses caused by human operational errors. In addition, because the capping mechanism 10 can achieve automated production, it improves work efficiency and further enhances operational safety.

[0039] Specifically, the first transmission member 121 includes a first transmission rod 1211 and a first gear 1212 arranged on the first transmission rod 1211, the second transmission member 122 includes a second transmission rod 1221 and a second gear 1222 arranged on the second transmission rod 1221, the first gear 1212 is engaged with the second gear 1222, the capping drive assembly 11 is driven and connected to the first transmission rod 1211, the first cover-kicking member 131 is connected to the first transmission rod 1211, and the second cover-kicking member 132 is connected to the second transmission rod 1221.

[0040] In this embodiment, the first transmission rod 1211 and the second transmission rod 1221 are arranged in parallel, the first gear 1212 is fixedly mounted on the first transmission rod 1211, and the second gear 1222 is fixedly mounted on the second transmission rod 1221. Under the drive of the capping drive assembly 11, the first transmission rod 1211 can accurately transmit power through gear transmission. The advantage of gear transmission is that it can ensure the accuracy and stability of power transmission. Even under high-speed operation or load changes, it can maintain a stable transmission ratio, thereby ensuring the accuracy and consistency of the capping action.

[0041] That is to say, under the driving action of the cover driving assembly 11, the first transmission rod 1211, since the first gear 1212 is fixed on the first transmission rod 1211, the first transmission rod 1211 transmits the force to the first gear 1212, and the second gear 1222 is engaged with the first gear 1212. Since the second gear 1222 is fixed on the second transmission rod 1221, the second gear 1222 transmits the force to the second transmission rod 1221, thereby realizing the power transmission between the first transmission member 121 and the second transmission member 122, so that the first transmission rod 1211 and the second transmission rod 1221 can move synchronously. Since the first transmission member 121 is connected to the first cover-strike member 131, and the second transmission member 122 is connected to the second cover-strike member 132, the first cover-strike member 131 and the second cover-strike member 132 can be opened or closed synchronously. At the same time, due to the accuracy of gear transmission, the first cover striking member 131 and the second cover striking member 132 can maintain a high degree of synchronization and coordination during their actions, thereby avoiding the problem of capping failure caused by inconsistent actions.

[0042] Alternatively, since the first transmission rod 1211 is drivably connected to the capping drive assembly 11, the first transmission rod 1211 may be an active rod, and the second transmission rod 1221 may be a driven rod. Alternatively, the second transmission rod 1221 may be drivably connected to the capping drive assembly 11, and thus the second transmission rod 1221 may be an active rod, and the first transmission rod 1211 may be a driven rod. The movement of the driven rod is restricted by the active rod, and the first transmission rod 1211 and the second transmission rod 1221 utilize gear meshing transmission to achieve the capping operation of the packaging box.

[0043] Furthermore, the capping drive assembly 11 includes a capping fixing member 111, a capping drive member 112 and a connecting member 113; one end of the capping drive member 112 is rotatably connected to the capping fixing member 111, and a retractable output shaft 1121 is provided at the other end of the capping drive member 112, the output shaft 1121 is rotatably connected to one end of the connecting member 113, and the other end of the connecting member 113 is drive-connected to the first transmission member 121.

[0044] In this embodiment, one end of the capping driver 112 is rotatably connected to the capping fixture 111 via a first pin 114. This ensures that the capping driver 112 maintains a stable position and angle during operation, thereby preventing unnecessary shaking or deviation during operation. A retractable output shaft 1121 is provided at the other end of the capping driver 112, allowing the capping driver 112 to retract and extend as needed, thereby driving the first transmission member 121 to rotate.

[0045] The first two ends of the first transmission rod 1211 are sleeved with first bearing seats 115, and the two ends of the second transmission rod 1221 are also sleeved with first bearing seats 115. The function of the bearing seats is to support the bearing and fix the outer ring of the bearing, allowing only the inner ring to rotate while the outer ring remains stationary. The two ends of the transmission rod are connected to the bearing through the bearing seats, so that the transmission rod can be firmly fixed, thereby ensuring that the transmission rod can normally transmit power and withstand external loads.

[0046] The connector 113 is specifically fastened to the first transmission rod 1211 using bolts, allowing the capping driver 112 to transmit power to the first transmission rod 1211 via the connector 113, thereby driving the entire capping mechanism 10 to move. The rotational connection between the connector 113 and the output shaft 1121 ensures that excessive friction or resistance is not generated during power transmission, thereby ensuring efficient and stable power transmission.

[0047] The capping drive member 112 may be a pneumatic cylinder, and the capping fixture 111 may be a cylinder fixture. The cylinder output shaft 1121 may be directly connected to the connector 113, eliminating the need for an additional transmission mechanism. This embodiment utilizes a single pneumatic cylinder to drive the first transmission rod 1211, with power transmitted via the first gear 1212 and the second gear 1222 to achieve synchronous capping of the first capping member 131 and the second capping member 132. This direct drive reduces energy loss and transmission error, thereby improving the operating efficiency of the capping mechanism 10.

[0048] In this embodiment, the capping drive assembly 11 also includes an adapter 116, one end of which is connected to the output shaft 1121, and the other end of the adapter 116 is rotatably connected to one end of the connecting member 113. The adapter 116 can convert the telescopic movement of the output shaft 1121 into the rotational movement of the connecting member 113.

[0049] Because the adapter 116 is directly connected to the output shaft 1121 and the connector 113, it accurately converts the cylinder's telescopic motion into the rotational motion of the connector 113, avoiding energy loss or transmission errors that may occur during the power transmission process. Therefore, the adapter 116 can adapt to different capping mechanisms 10 and capping requirements. Whether it is a rotary capping or a clamping capping, the adapter 116 can be adjusted according to specific needs to meet different capping operations.

[0050] Specifically, the other end of the adapter 116 is rotatably connected to one end of the connector 113 via a second pin 117. The first pin 114 and the second pin 117 are parallel to each other, and both the first pin 114 and the second pin 117 are parallel to the first transmission rod 1211 and the second transmission rod 1221 in the transmission assembly 12. The adapter 116 includes a first adapter and a second adapter, which are arranged vertically to form a T-shaped structure. One end of the first adapter is connected to the output shaft 1121, and the other end of the first adapter is connected to the second adapter. The second adapter is rotatably connected to one end of the connector 113 via the second pin 117. Among them, the whole formed by the capping drive 112 (including the output shaft 1121) is perpendicular to the first pin shaft 114 and the second pin shaft 117, and the connecting member 113 is perpendicular to the first transmission rod 1211 and the output shaft 1121, so that the connecting member 113, the second pin shaft 117, the adapter 116, the capping drive 112 (including the output shaft 1121), and the first pin shaft 114 constitute a connecting rod motion mechanism.

[0051] Further, such as Figure 2 As shown, the first striking cover member 131 includes a first bending portion 1311 and a first striking cover portion 1312, and the second striking cover member 132 includes a second bending portion 1321 and a second striking cover portion 1322. The two ends of the first bending portion 1311 are respectively connected to the first transmission member 121 and the first striking cover portion 1312, and the two ends of the second bending portion 1321 are respectively connected to the second transmission member 122 and the second striking cover portion 1322. Protective members are provided on the first striking cover portion 1312 and the second striking cover portion 1322.

[0052] In this embodiment, the first bending portion 1311 and the second bending portion 1321 serve as a bridge connecting the transmission assembly 12 and the first cover-strike portion 1312 and the second cover-strike portion 1322, which not only ensures the stability and reliability of the cover-strike assembly 13 during movement, but also allows the cover-strike assembly 13 to be adjusted to a certain angle according to the layout of the sealing mechanism 10, thereby ensuring that the first cover-strike portion 1312 and the second cover-strike portion 1322 can accurately and effectively seal the packaging box.

[0053] Specifically, the first striking cover part 1312 and the second striking cover part 1322 are arranged in parallel. Preferably, the first striking cover part 1312 and the second striking cover part 1322 are cylindrical structures with a longer length and a predetermined length, so that the contact area with the box cover can be increased and the sealing effect can be improved.

[0054] The protective part can be made of soft rubber material. The function of the protective part is to prevent wear, collision or scratches caused by direct contact between the first cover-striking part 1312 and the second cover-striking part 1322 and the packaging box cover during the sealing process, while improving the stability and comfort of the sealing process.

[0055] In a specific application embodiment, Figure 2 As shown, the output shaft 1121 of the cylinder is in an extended state. At this time, the first cover member 131 and the first cover member 131 are in an open state. After the air conditioner indoor unit with the package box is waiting to enter the bottom of the capping mechanism 10 through the assembly line, the output shaft 1121 of the cylinder begins to shrink. The shrinkage of the output shaft 1121 drives one end of the connecting member 113 to be pulled back. The position where the other end of the connecting member 113 is connected to the first transmission rod 1211 is used as the rotation center axis. The connecting member 113 will rotate counterclockwise along the rotation center axis. The rotation of the connecting member 113 drives the first transmission rod 1211 to rotate. The first transmission rod 1211 then transmits the signal to the first gear 1212. The second gear 1222 is engaged with the first gear 1212. The second gear 1222 is then transmitted to the second transmission rod 1221. Figure 3 As shown, at the same time, the first striking cover member 131 and the first striking cover member 131 are clamped, and the first striking cover portion 1312 and the second striking cover portion 1322 are in direct contact with the box cover, thereby completing the sealing of the packaging box.

[0056] After the capping is completed, the output shaft 1121 of the cylinder is in a retracted state. At this time, the first capping member 131 and the first capping member 131 are in a closed state. The air conditioner indoor unit with the package box is sent out from the bottom of the capping mechanism 10. At this time, the output shaft 1121 of the cylinder begins to extend. The output shaft 1121 extends to drive one end of the connecting member 113 to be pushed away. The position where the other end of the connecting member 113 is connected to the first transmission rod 1211 is used as the rotation center axis. The connecting member 113 will rotate clockwise along the rotation center axis. The rotation of the connecting member 113 drives the first transmission rod 1211 to rotate. The first transmission rod 1211 then transmits the signal to the first gear 1212. The second gear 1222 is engaged with the first gear 1212. The second gear 1222 is then transmitted to the second transmission rod 1221. Figure 3 As shown, at the same time, the first striking cover member 131 and the first striking cover member 131 are opened, waiting for the air conditioner indoor unit with the package box to enter the bottom of the sealing mechanism 10 through the assembly line and perform subsequent actions.

[0057] During the above movement process, the capping driving member 112 (including the output shaft 1121 ) itself combined with the adapter will also rotate around the first pin shaft 114 and the second pin shaft 117 as part of the connecting rod movement mechanism.

[0058] Further, combined Figure 4 and Figure 7 As shown, the packaging box covering device further includes a positioning mechanism 20, which includes a horizontal positioning mechanism 21 and a vertical positioning mechanism 22. The horizontal positioning mechanism 21 and the vertical positioning mechanism 22 are used to adjust the horizontal position and the vertical position of the covering mechanism 10 respectively;

[0059] The capping mechanism 10 is arranged on the horizontal positioning mechanism 21 , and the horizontal positioning mechanism 21 is arranged on the vertical positioning mechanism 22 . Alternatively, the capping mechanism 10 is arranged on the vertical positioning mechanism 22 , and the vertical positioning mechanism 22 is arranged on the horizontal positioning mechanism 21 .

[0060] In this embodiment, the horizontal positioning mechanism 21 and the vertical positioning mechanism 22 ensure the precise positioning of the capping mechanism 10 in the horizontal and vertical directions. The horizontal positioning mechanism 21 is responsible for adjusting the horizontal position of the capping mechanism 10 to ensure that the capping mechanism 10 can accurately align with the opening position of the packaging box. The adjustment of the horizontal position can be achieved by sliding to accommodate packaging boxes of different sizes or different capping position requirements. The vertical positioning mechanism 22 is responsible for adjusting the vertical position of the capping mechanism 10 to ensure that the appropriate spacing and angle are maintained between the capping mechanism 10 and the packaging box. The adjustment of the vertical position can be achieved by lifting to accommodate packaging boxes of different heights or different capping angle requirements.

[0061] In a specific embodiment, the capping mechanism 10 can be mounted on the horizontal positioning mechanism 21, which is then mounted on the vertical positioning mechanism 22. This allows for more flexible adaptation to different capping tasks by adjusting the horizontal position first and then the vertical position. Another approach is to mount the capping mechanism 10 directly on the vertical positioning mechanism 22, which is then mounted on the horizontal positioning mechanism 21.

[0062] Regardless of which arrangement is adopted, the positioning mechanism 20 enables the capping mechanism 10 to adapt to packaging boxes of different sizes, shapes, and heights, as well as different capping positions and angles, thereby improving production efficiency.

[0063] Specifically, the horizontal positioning mechanism 21 includes: a horizontal bracket 211, a guide rail 212, a slider 213, a horizontal drive assembly 214 and a cover support 215. The guide rail 212 is horizontally arranged on the horizontal bracket 211, the slider 213 is slidably arranged on the guide rail 212, the horizontal drive assembly 214 drives the connected slider 213, the cover support 215 is arranged on the slider 213, and the cover mechanism 10 is arranged below the cover support 215.

[0064] There are two horizontal brackets 211, and the guide rail 212 is horizontally set between the two horizontal brackets 211. The slider 213 is slidably set on the guide rail 212. The slider 213 is a component connecting the horizontal driving component 214 and the cover support 215. The horizontal driving component 214 drives the slider 213 to slide on the guide rail 212. Through the sliding of the slider 213 on the guide rail 212, the cover support 215 is set on the slider 213, so that the cover mechanism 10 can be precisely adjusted in the horizontal direction.

[0065] Combine Figures 4 to 6 As shown, in this embodiment, the horizontal drive assembly 214 includes a translation support frame 2141, a translation drive member 2142, a translation gear 2143 and a rack 2144, the rack 2144 is horizontally arranged on the horizontal support 211, the translation gear 2143 is connected to the output end of the translation drive member 2142, the translation gear 2143 and the rack 2144 are engaged, the translation drive member 2142 is arranged on the translation support frame 2141, and the translation support frame 2141 is connected to the slider 213.

[0066] The translation drive 2142 can be a motor, a cylinder, or another type of driver. A translation gear 2143 is connected to the translation drive 2142 and the rack 2144. The translation drive 2142 drives the translation gear 2143 to rotate, thereby causing the translation gear 2143 to move horizontally on the rack 2144, thereby driving the slider 213 to slide on the guide rail 212. The meshing transmission between the translation gear 2143 and the rack 2144 offers advantages such as high precision, high stability, and low noise, enabling rapid, smooth, and accurate horizontal movement of the slider 213.

[0067] Furthermore, the vertical positioning mechanism 22 includes a frame 221 , a lifting assembly 222 and a lifting carrier 223 . The lifting assembly 222 is disposed on the frame 221 . The lifting assembly 222 can drive the lifting carrier 223 to move up and down. The horizontal positioning mechanism 21 is disposed on the lifting carrier 223 .

[0068] In this embodiment, the horizontal positioning mechanism 21 is arranged on the lifting carrier 223. Since the covering mechanism 10 is connected to the covering support 215 under the horizontal positioning mechanism 21, specifically, the covering support 215 and the covering fixing member 111 are fixedly connected by square welding. When the lifting carrier 223 moves up and down driven by the lifting component 222, the horizontal positioning mechanism 21 will move up and down with the lifting carrier 223, and the covering mechanism 10 connected under the horizontal positioning mechanism 21 will also move up and down, thereby accurately positioning the height position of the covering mechanism 10 according to the height position of the packaging box.

[0069] Specifically, the lifting assembly 222 includes a lifting drive 2221, a ball screw 2222 and a guide rod 2223. The ball screw 2222 is vertically arranged on the lifting carrier 223 and can drive the lifting carrier 223 to move up and down. The guide rod 2223 is vertically arranged on the lifting carrier 223 and can guide the movement of the lifting carrier 223. The lifting drive 2221 is arranged on the frame 221 and is driven and connected to the ball screw 2222.

[0070] The lifting drive 2221 can be driven by a servo motor, hydraulic pressure, or pneumatic pressure to ensure stable and continuous power output. The ball screw 2222 is vertically arranged on the lifting vehicle 223 and can accurately control the up and down movement of the lifting vehicle 223 through the driving connection with the lifting drive 2221.

[0071] Specifically, a ball screw converts rotary motion into linear motion. Ball screw 2222 consists of three main components: a screw, a nut, and a ball. The screw and nut have helical lines on their surfaces. Driven by the motor of the lift drive 2221, the rotational force is transmitted to the screw. The ball rolls between the screw and nut, converting the screw's rotary motion into the nut's linear motion. In other words, when the screw rotates, the nut moves along the helical line, achieving linear motion.

[0072] The guide rod 2223 can adopt a linear bearing, which is used in conjunction with the guide shaft to provide low-friction guide support for the linear motion of the nut.

[0073] In specific application examples, such as Figure 7 As shown, the packaging box covering device is installed as a whole on the air-conditioning indoor unit assembly line. The installation of the packaging box covering device needs to ensure horizontal and vertical movement. The first striking cover part 1312 and the second striking cover part 1322 that are in direct contact with the packaging box are parallel to the packaging box, and the direct contact surface adopts soft protection to prevent the device from damaging the air-conditioning indoor unit packaging box during operation.

[0074] The frame 221 is formed by square welding, and the vertical positioning mechanism 22 is installed on the frame 221. The horizontal positioning mechanism 21 is arranged on the vertical positioning mechanism 22. The vertical positioning mechanism 22 uses a ball screw 2222 as a transmission mechanism and a guide rod 2223 (the guide rod 2223 can be a linear bearing) as a guide mechanism. One end of the screw is connected to the second bearing seat, and the other end is connected to the lifting drive member 2221. There are two ball screws 2222, which are distributed at the diagonal positions of the frame 221. There are also two guide rods 2223, which are distributed at the diagonal positions of the frame 221, forming a two-by-two cross distribution pattern with the two ball screws 2222. This distribution form ensures that the two screws are evenly stressed during the lifting process, thereby improving the lifting accuracy. The horizontal positioning mechanism 21 uses two horizontal brackets 211 as movable crossbeams. A guide rail 212 and a slider 213 are fixed beneath the crossbeams. A capping support 215 is attached to the slider 213. A translation driver 2142 is mounted above the slider 213. The translation servo mechanism is driven by a rack and pinion 2144 and guided by the guide rail 212 and slider 213. This allows precise control of the horizontal and vertical movement of the capping mechanism 10.

[0075] In other embodiments, because the models of air conditioner indoor units often change, the sizes of the boxes in which they are packaged may also vary. When the box changes, the positioning mechanism 20 automatically locates itself to the target position for sealing according to a pre-programmed procedure. This means that when changing to a box of a different size, there is no need to manually adjust the positioning mechanism 20; it automatically positions itself according to the pre-programmed procedure, ensuring accurate sealing. If the boxed indoor air conditioner is not guided by a guide mechanism before entering the box-sealing device, the positioning mechanism 20 can also cooperate with a vision system to confirm the position of the indoor air conditioner before entering the box-sealing device, and then move the positioning mechanism 20 to that position for sealing.
