[0037] First embodiment

[0038] See also Figure 1 , Figure 2 and Figure 3 In the first aspect, an embodiment of the present application provides a box sealing device, including a transport mechanism 10 and a box buckle mechanism 20, the transport mechanism 10 is used to transport a packaging box 30 in an opened state, and at least one material placement position is provided on the transport mechanism 10; the box buckle mechanism 20 is arranged on one side of the transport mechanism 10, and includes a top cover buckle assembly 21, the top cover buckle assembly 21 includes a first pressing plate 211, the first pressing plate 211 is located on one side of the material placement position along a first direction X, the first pressing plate 211 is rotatably arranged along a first axis, and is used to push the top cover 31 of the packaging box 30, so that the top cover body 311 of the top cover 31 covers the opening of the box body 32 of the packaging box 30 and the top tongue 312 of the top cover 31 is inserted into the interior of the box body 32, the first axis extends along a second direction Y, and the first direction X and the second direction Y are arranged to intersect.

[0039] It should be clear that the first direction X can be any one of the width direction and the length direction of the transport mechanism 10, the second direction Y can be the other, and the length direction of the transport mechanism 10 is the transport direction of the transport mechanism 10. Optionally, the transport mechanism 10 can be any one of a roller conveyor line, a chain plate conveyor line, a belt conveyor line, a flat top chain conveyor line, a flexible chain plate conveyor line, a double speed chain conveyor line and a mesh belt conveyor line. In the present application, upstream and downstream are relative, and upstream refers to an end or a distance that the packaging box 30 preferentially passes through during the process of being transported by the transport mechanism 10 relative to the downstream, and downstream refers to an end or a distance that the packaging box 30 needs to pass through after passing the upstream relative to the upstream, that is, the transport mechanism 10 transports the packaging box 30 from the upstream to the downstream direction. When the transport mechanism 10 includes a head end and a tail end, and the transport mechanism 10 transports the packaging box 30 from the head end to the tail end, the upstream is closer to the head end relative to the downstream, and the downstream is closer to the tail end relative to the upstream.

[0040] The packaging box 30 may include a box body 32 and a top cover 31. The box body 32 has an opening. The top cover 31 is arranged at the opening of the box body 32. The top cover 31 includes a top cover body 311 and a top tongue 312 arranged on the top cover body 311. The top cover body 311 includes a first side and a second side arranged opposite to each other. The first side of the top cover body 311 is connected to the box body 32, and the top tongue 312 is connected to the second side of the top cover body 311. The packaging box 30 includes an open state and a closed state. In the open state, the top cover body 311 unfolds to the side away from the opening to expose the opening of the box body 32. In the closed state, the top cover body 311 covers the opening of the box body 32, and the top tongue 312 is inserted into the opening of the box body 32 from the gap between the box body 32 and the top cover body 311.

[0041] In the transport mechanism 10 , the placement position is used to place the packaging box 30 in an opened state. When the transport mechanism 10 includes a plurality of placement positions, the plurality of placement positions can be arranged in sequence along the second direction Y at intervals. It can be understood that when the packaging box 30 in the opened state is placed at the loading position, the top cover 31 of the packaging box 30 can be located along the first direction X on the side of the box body 32 close to the first pressure plate 211. When the packaging box 30 is transported to the box buckle mechanism 20, since the first pressure plate 211 is arranged on the side of the loading position along the first direction X, and the first pressure plate 211 can rotate relative to the first axis, and the first axis extends along the second direction Y, the first pressure plate 211 can fit with the top cover body 311 of the top cover 31 during the rotation process and push the top cover body 311 to rotate together, so that the top cover body 311 can rotate to cover the opening of the box body 32. At the same time, when the top cover body 311 covers the opening of the box body 32, the top tongue 312 on the top cover 31 can be inserted into the box body 32 from the gap between the top cover body 311 and the box body 32, thereby realizing automatic sealing of the packaging box 30.

[0042] In the box sealing device provided in the embodiment of the present application, the packaging box 30 in an open state is placed on the loading position of the transportation mechanism 10, and the top cover 31 of the packaging box 30 is located on the side of the box body 32 close to the first pressure plate 211 along the first direction X. When the transportation mechanism 10 drives the packaging box 30 to move to the buckle mechanism 20, since the first pressure plate 211 is located on the side of the loading position along the first direction X, and the first axis extends along the second direction Y, therefore, during the rotation of the first pressure plate 211 along the first axis, the first pressure plate 211 can fit with the top cover body 311 of the top cover 31 and push the top cover body 311 to rotate to cover the opening of the box body 32. At the same time, the top tongue 312 of the top cover 31 can be inserted into the box body 32 from the gap between the top cover body 311 and the box body 32 when the top cover body 311 covers the opening of the box body 32, thereby realizing automatic box sealing of the packaging box 30, thereby improving box sealing efficiency and reducing labor costs.

[0043] Optionally, the top cover snap-fit ​​assembly 21 may further include a rotating shaft and a telescopic member, the first pressure plate 211 is rotatably connected to the rotating shaft, the rotating shaft extends along the second direction Y, the telescopic member is connected to the side of the first pressure plate 211 away from the material placement position along the first direction X, the telescopic member can be telescopically arranged in a direction close to or away from the material placement position, so that the first pressure plate 211 can be driven to rotate relative to the rotating shaft through the extension and retraction of the telescopic member, thereby pushing the top cover body 311 to rotate to cover the opening of the box body 32.

[0044] Please continue to refer to Figure 2 According to the first aspect of the embodiment of the present application, the carton sealing device also includes a pre-folding mechanism 40 arranged on one side of the transport mechanism 10, and the pre-folding mechanism 40 is located upstream of the buckle box mechanism 20, and is used to bend the top tongue 312 of the top cover 31 relative to the top cover body 311.

[0045] The pre-folding mechanism 40 can pre-bend the top tongue 312 on the top cover 31 of the packaging box 30 in an open state on the transportation mechanism 10 at a certain angle to form a crease between the top tongue 312 and the top cover body 311. Therefore, when the top cover buckling assembly 21 of the buckle box mechanism 20 pushes the top cover 31 and makes the top cover body 311 cover the opening of the box body 32 of the packaging box 30, the top tongue 312 can be automatically inserted into the opening from the gap between the top cover body 311 and the box body 32 to achieve the closure of the packaging box 30, thereby reducing the difficulty of the buckle box mechanism 20 to close the packaging box 30.

[0046] Please refer to Figure 4 According to the first aspect of the embodiment of the present application, the pre-folding mechanism 40 includes a fixing component 41, a top tongue pre-folding component 42 and a side ear pre-folding component 43. The fixing component 41 is located on one side of the material placement position along the first direction X, and is used to fix the top cover body 311. Part of the top tongue pre-folding component 42 is movably arranged along the first direction X, and is used to push the top tongue 312 to bend relative to the top cover body 311. The side ear pre-folding component 43 is movably arranged along the second direction Y, and is used to push the side ears 33 of the packaging box 30 to bend.

[0047] Please continue to refer to Figure 1It can be understood that the packaging box 30 can also include two side ears 33, which are arranged on opposite sides of the opening of the box body 32, and the top cover 31 is located between the two side ears 33. When the packaging box 30 is in an open state, the side ears 33 and the top cover body 311 are unfolded together to the side away from the opening to expose the opening of the box body 32. When the packaging box 30 is in a closed state, the top cover body 311 and the two side ears 33 overlap and cover the opening of the box body 32. The fixing component 41 is used to fix the top cover body 311. Optionally, the fixing component 41 can be composed of any structure that can fix the top cover body 311, such as a clamp, a suction cup, a manipulator, etc. After the fixing component 41 fixes the top cover body 311, the top tongue pre-folding component 42 is controlled to move along the first direction X so that the top tongue 312 can be pushed along the first direction X so that the top tongue 312 is bent relative to the top cover body 311, thereby achieving the pre-folding of the top tongue 312. At the same time, the side ear pre-folding component 43 is controlled to move along the second direction Y so that the side ear pre-folding component 43 pushes the side ear 33 along the second direction Y so that the side ear 33 is bent in the direction of covering the opening, thereby achieving the pre-folding of the side ear 33.

[0048] In this embodiment, before the packaging box 30 is transported to the buckle box mechanism 20, the top cover body 311 is fixed by the fixing assembly 41, and the top tongue 312 is pushed to bend along the first direction X by the top tongue pre-folding assembly 42, and the side ear 33 is pushed to bend along the second direction Y by the side ear pre-folding assembly 43, thereby realizing the pre-folding of the top tongue 312 and the side ear 33, thereby further reducing the difficulty of sealing the box by the buckle box mechanism 20.

[0049] The top tongue pre-folding assembly 42 and / or the side ear pre-folding assembly 43 may include at least one of linear driving components such as a linear guide, a linear motor, a linear cylinder and a hydraulic cylinder, or the top tongue pre-folding assembly 42 and / or the side ear pre-folding assembly 43 may also be a combination structure of a rotating driving structure such as a rotating motor, a rotating cylinder and a connecting rod, which is not limited in this embodiment.

[0050] Optionally, there may be a plurality of side ear pre-folding components 43 , and the plurality of side ear pre-folding components 43 are spaced apart along the second direction Y to ensure the pre-folding effect of the side ears 33 of the packaging box 30 .

[0051] Please continue to refer to Figure 4 According to the first aspect of the embodiment of the present application, the fixing assembly 41 includes a first limiting rod 411 and a second limiting rod 412 spaced apart along a first direction X, the first limiting rod 411 and the second limiting rod 412 extend along a second direction Y respectively, and a first clamping space is formed between the first limiting rod 411 and the second limiting rod 412 for clamping the top cover body 311, and the second direction Y is the transport direction of the transport mechanism 10.

[0052] The second direction Y is the transport direction of the transport mechanism 10, that is, the length direction of the transport mechanism 10, and the first direction X is the width direction of the transport mechanism 10. In the fixing assembly 41, the first limiting rod 411 and the second limiting rod 412 both extend along the second direction Y, and the first limiting rod 411 and the second limiting rod 412 are spaced apart along the first direction X, so that a first clamping space can be formed between the first limiting rod 411 and the second limiting rod 412, and the first clamping space can clamp the top cover body 311 along the first direction X to fix the top cover body 311 along the first direction X, and the structure is simple. Furthermore, since the first limiting rod 411 and the second limiting rod 412 both extend along the second direction Y, and the first limiting rod 411 and the second limiting rod 412 are spaced apart along the first direction X, the first clamping space can have openings on both sides along the second direction Y. During the process of the transport mechanism 10 transporting the packaging box 30 along the second direction Y, the top cover body 311 of the packaging box 30 can automatically enter the first clamping space from one opening and move from the other opening to the outside of the first clamping space, so that the top cover body 311 can be clamped in the first clamping space between the first limiting rod 411 and the second limiting rod 412 without the need for additional action, thereby reducing the difficulty of the fixing assembly 41 in fixing the top cover body 311.

[0053] Please continue to refer to Figure 4 According to the first aspect of the embodiment of the present application, the top tongue pre-folding assembly 42 includes a first driving member and a first push plate connected to the first driving member, the first driving member is used to drive the first push plate to move along the first direction X; and / or, the side ear pre-folding assembly 43 includes two pre-folding members relatively arranged along the second direction Y, the two pre-folding members are used to bend the two side ears 33 of the packaging box 30 in a one-to-one correspondence, the pre-folding member includes a first rotating driving component 431 and a second push plate 432 connected to the first rotating driving component 431, the first rotating driving component 431 rotates along the second axis, the second axis extends along the third direction Z, and the third direction Z is perpendicular to the first direction X and the second direction Y, respectively.

[0054] The third direction Z may be the height direction or the thickness direction of the transport mechanism 10. In the top tongue pre-folding assembly 42, the first driving member may include but is not limited to linear driving members such as linear guides, linear motors, linear cylinders and hydraulic cylinders. The first push plate is connected to the first driving member to move along the first direction X under the drive of the first driving member, so that the top tongue 312 of the packaging box 30 can be pushed to bend along the first direction X. The structure is simple and the operation is convenient. In the side ear pre-folding assembly 43, the two pre-folding members are relatively arranged along the second direction Y, so that the side ears 33 located on the opposite sides of the box body 32 can be pre-folded one by one through the two pre-folding members. In the pre-folding member, the first rotating driving component 431 can be any structure that can realize rotational drive, such as a rotating motor and a rotating cylinder. The first rotating driving component 431 can drive the second push plate 432 to rotate along the second axis. Since the second axis extends along the third direction Z, during the rotation of the second push plate 432, the side of the second push plate 432 away from the first rotating driving component 431 is equivalent to moving along the first direction X and the second direction Y, so that the side ear 33 can be pushed to bend along the second direction Y. The structure is simple and the operation is convenient.

[0055] Please refer to Figure 3 According to the first aspect of the embodiment of the present application, the buckle box mechanism 20 also includes a side ear buckle assembly 22, the side ear buckle assembly 22 includes a rotating drive member 221 and two third push plates 222 arranged opposite to each other along the second direction Y, the third push plates 222 are connected to the rotating drive member 221, and are used to push the side ear 33 along the second direction Y under the drive of the rotating drive member 221.

[0056] It is understandable that the side ears 33 of the packaging box 30 may rebound after being pre-folded during the process of being transported to the buckle box mechanism 20, making it difficult to cover the opening of the box body 32. Therefore, in this embodiment, a side ear buckle assembly 22 is provided at the buckle box mechanism 20, and the side ear buckle assembly 22 includes a rotary drive member 221 and two third push plates 222 arranged opposite to each other along the second direction Y. The third push plates 222 are connected to the rotary drive member 221, so that the rotary drive member 221 drives the third push plates 222 to move along the second direction Y, so as to push the side ears 33 of the packaging box 30 to bend again, so as to ensure that the side ears 33 can cover the opening of the box body 32. The rotary drive member 221 can be any structure that can realize rotary drive, such as a rotary motor, a rotary cylinder, etc., and this embodiment does not limit it.

[0057] According to the first aspect of the embodiment of the present application, the rotating driving member 221 includes a cylinder 223 and two transmission members, the transmission members include a rack, a gear and a connecting rod 224 coaxially connected to the gear, the piston rod of the cylinder 223 is connected to the rack, and the piston rod and the rack both extend along the first direction X, the rack and the gear are meshed with each other, and the two third push plates 222 are respectively connected to the connecting rods 224 of the two transmission members.

[0058] The piston rod and the rack of the cylinder 223 both extend in the first direction X, so the rack can be driven to move in the first direction X by the cylinder 223. Since the rack is meshed with the gear, the gear can be driven to rotate along the third axis by the rack, thereby driving the connecting rod 224 coaxially connected to the gear to rotate. Since the two third push plates 222 are connected to the connecting rods 224 of the two transmission members in a one-to-one correspondence, during the rotation of the connecting rod 224, the third push plates 222 can be driven by the connecting rod 224 to move in the second direction Y, thereby pushing the corresponding side ears 33 to bend, with a simple structure and stable transmission. It can be understood that since the rack extends in the first direction X, the third axis of the gear meshed with the rack can be an axis extending in the third direction Z. Of course, the third axis can also extend in other directions intersecting with the first direction X, as long as the extension direction of the third axis is located in the plane where the first direction X and the third direction Z are located.

[0059] Optionally, the second push plate 432 and / or the third push plate 222 may include a connecting portion, an intermediate portion and an abutting portion which are arranged in sequence, the connecting portion of the second push plate 432 is connected to the first rotation driving component 431, the connecting portion of the third push plate 222 is connected to the second rotation driving component, the abutting portion is used to abut the side ear 33 of the packaging box 30, and the intermediate portion can be bent toward a side away from the material placement position relative to the connecting portion and the abutting portion to form an avoidance portion to avoid other structures in the pre-folding mechanism 40 and / or the buckle box mechanism 20.

[0060] Please refer to Figure 1 and Figure 5 According to the first aspect of the embodiment of the present application, the box sealing device also includes a buckle forming mechanism 50 for pressurizing the buckle 34 on the box body 32 of the packaging box 30, the buckle forming mechanism 50 and the pre-folding mechanism 40 are arranged opposite to each other along the first direction X, the buckle forming mechanism 50 includes a forming plate 51 and a second driving member 52, the forming plate 51 includes a first sub-plate 511, a second sub-plate 512 and a third sub-plate 513 connected in sequence, the first sub-plate 511 is arranged opposite to the transportation mechanism 10 along the third direction Z, and the second sub-plate 512 is arranged at a distance from the transportation mechanism 10. The first sub-plate 511 is bent along the first direction X on a side close to the pre-folding mechanism 40, and relative to the first sub-plate 511 along the third direction Z toward a side close to the transport mechanism 10, and the third sub-plate 513 is bent along the first direction X toward a side away from the pre-folding mechanism 40 relative to the second sub-plate 512; the second driving member 52 is connected to the first sub-plate 511, and is used to drive the forming plate 51 to move along the first direction X and the third direction Z, the second direction Y is the transport direction of the transport mechanism 10, and the third direction Z is perpendicular to the first direction X and the second direction Y, respectively.

[0061] It can be understood that in the packaging box 30, in order to improve the reliability of the packaging box 30 after being sealed, a socket can be set between the top cover body 311 of the top cover 31 and the top tongue 312, and a buckle 34 can be set on the box body 32, and the buckle 34 and the top cover 31 are located on opposite sides of the box body 32. Therefore, when the top cover body 311 covers the opening of the box body 32 and the top tongue 312 is inserted into the box body 32 from the gap between the top cover body 311 and the box body 32, the buckle 34 on the box body 32 can be inserted into the socket of the top cover 31, thereby further fixing the box body 32 and the top cover 31, thereby improving the reliability of the packaging box 30 after being sealed.

[0062] The buckle forming mechanism 50 is used to form the buckle 34 on the box body 32. Specifically, the buckle forming mechanism 50 and the pre-folding mechanism 40 are arranged opposite to each other along the first direction X, and the two can be arranged on opposite sides of the first direction X close to the material placement position, respectively. At this time, the buckle 34 formed by the buckle forming mechanism 50 and the top cover 31 can be respectively located on opposite sides of the box body 32. In the buckle forming mechanism 50, the forming plate 51 includes a first sub-plate 511, a second sub-plate 512 and a third sub-plate 513 connected in sequence, the first sub-plate 511 is arranged relative to the transport mechanism 10 along the third direction Z, the second sub-plate 512 is located on the side of the first sub-plate 511 close to the pre-folding mechanism 40 along the first direction X, and is bent toward the side close to the transport mechanism 10 along the third direction Z relative to the first sub-plate 511, that is, the plane where the first sub-plate 511 is located intersects or is perpendicular to the plane where the second sub-plate 512 is located, and the second sub-plate 512 is located on the side of the first sub-plate 511 close to the transport mechanism 10 along the third direction Z, and the third sub-plate 513 ... pre-folding mechanism 40 along the first direction X, and is bent toward the side close to the transport mechanism 10 along the third direction Z relative to the first sub-plate 511, that is, the plane where the first sub-plate 511 is located is intersecting or perpendicular to the plane where the second sub-plate 512 is located, and the second sub-plate 512 is The sub-plate 513 is bent relative to the second sub-plate 512 along the first direction X toward the side away from the pre-folding mechanism 40. Therefore, when the transportation mechanism 10 drives the packaging box 30 to move to the buckle forming mechanism 50, the second driving member 52 drives the forming plate 51 to move along the first direction X and the third direction Z, so that the second sub-plate 512 and the third sub-plate 513 of the forming plate 51 move to the interior of the box body 32, and then the second driving member 52 drives the forming plate 51 to move along the first direction X toward the side away from the pre-folding mechanism 40, so that the third sub-plate 513 can push the part of the box body 32 corresponding to the buckle 34 to bend toward the side away from the pre-folding mechanism 40 to form the buckle 34.

[0063] In this embodiment, the buckle 34 on the box body 32 is automatically formed by the buckle forming mechanism 50, without the need for manual processing of the buckle 34, which can improve the box sealing efficiency and reduce labor costs. In addition, the buckle 34 can be pressed and formed by the second driving member 52 driving the forming plate 51 to move along the first direction X and the third direction Z, which has a simple structure and is easy to operate.

[0064] Optionally, the second driving member 52 may include at least two of linear driving members such as a linear guide, a linear motor, a linear cylinder, and a hydraulic cylinder; or, the second driving member 52 may also include any one of a rotary driving structure such as a rotary motor and a rotary cylinder. In this case, the rotary driving member 221 may rotate along the fourth axis, and the fourth axis extends along the second direction Y, thereby driving the forming plate 51 to move along the first direction X and the third direction Z. For example, when the second driving member 52 is a rotary cylinder, the rotary cylinder is connected to the first sub-plate 511 of the forming plate 51, and the rotary cylinder rotates along the fourth axis, thereby driving the forming plate 51 to move along the first direction X and the third direction Z.

[0065] According to the first aspect of the embodiment of the present application, the buckle box mechanism 20 also includes a buckle plug-in component, which is arranged relative to the top cover buckle component 21 along the first direction X, and part of the buckle plug-in component is movably arranged along the first direction X, and is used to push the buckle 34 on the box body 32 to be plugged into the socket of the top cover 31.

[0066] It can be understood that, since the buckle 34 and the top cover 31 are located on opposite sides of the box body 32, the buckle plug-in assembly and the top cover buckle assembly 21 are arranged relatively along the first direction X. After the top cover buckle assembly 21 buckles the top cover 31 to cover the opening of the box body 32, the buckle plug-in assembly can push the buckle 34 into the socket of the top cover 31 to achieve the buckle connection between the buckle 34 and the top cover 31. The structure is simple and the operation is convenient. In addition, the buckle 34 is automatically plugged into the socket of the top cover 31 by the buckle plug-in assembly, which can further improve the sealing efficiency and reduce the labor cost compared with manual plug-in. The buckle plug-in assembly can be any one of the linear drive components such as a linear guide, a linear motor, a linear cylinder, and a hydraulic cylinder, so as to be able to push the buckle 34 along the first direction X.

[0067] Please continue to refer to Figure 3 According to the first aspect of the embodiment of the present application, the buckle box mechanism 20 also includes a tongue forming assembly 23 arranged relative to the transport mechanism 10 along the third direction Z, the tongue forming assembly 23 includes a fourth driving member 231 and a second pressure plate connected to the fourth driving member 231, the second pressure plate includes a fourth sub-plate 232 and a fifth sub-plate 233, the fourth sub-plate 232 is connected to the fourth driving member 231, the fifth sub-plate 233 is arranged on the side of the fourth sub-plate 232 away from the material placement position along the first direction X, and protrudes relative to the fourth sub-plate 232 toward the side close to the transport mechanism 10 along the third direction Z, the fourth sub-plate 232 is used to fit with the tongue 312, the fifth sub-plate 233 is used to fit with the top cover body 311, the angle between the fourth sub-plate 232 and the fifth sub-plate 233 is less than or equal to 90°, and the third direction Z is perpendicular to the first direction X and the second direction Y, respectively.

[0068] It is understandable that after being pre-folded, the top tongue 312 of the top cover 31 may rebound during the process of being transported to the buckle box mechanism 20, making it difficult to insert into the box body 32 through the gap between the box body 32 and the top cover body 311.

[0069] Therefore, in this embodiment, the fifth sub-plate 233 is arranged on the side of the fourth sub-plate 232 away from the material placement position along the first direction X, and protrudes toward the side close to the transportation mechanism 10 relative to the fourth sub-plate 232 along the third direction Z. Therefore, the second pressure plate is driven by the fourth driving member 231 to move toward the direction close to the transportation mechanism 10 along the third direction Z, so that the fourth sub-plate 232 can be fitted with the top tongue 312, and the fifth sub-plate 233 can be fitted with the top cover body 311. Since the plane where the fourth sub-plate 232 is located is perpendicular to the plane where the fifth sub-plate 233 is located, the top tongue 312 is bent at approximately 90° relative to the top cover body 311, thereby realizing the molding of the top tongue 312, thereby facilitating the insertion of the top tongue 312 into the box body 32 from the gap between the box body 32 and the top cover body 311.

[0070] Please continue to refer to Figure 3 , and / or, the buckle box mechanism 20 also includes a guide assembly 24, the guide assembly 24 and the top cover buckle assembly 21 are arranged opposite to each other along the first direction X, the guide assembly 24 includes at least one guide plate 241, the guide plate 241 is formed with a guide surface along the second direction Y toward the side of the top cover buckle assembly 21, the guide surface is bent from the end close to the transport mechanism 10 to the end away from the transport mechanism 10 toward the side close to the top cover buckle assembly 21, and is used to resist the top tongue 312 in the process of the first pressing plate 211 pushing the top cover 31 to cover the opening of the box body 32. Therefore, in the process of the first pressing plate 211 pushing the top cover 31 so that the top cover body 311 covers the opening of the box body 32, the top tongue 312 is resisted by the guide surface of the guide plate 241, so as to prevent the top tongue 312 from rebounding.

[0071] Optionally, there may be a plurality of guide plates 241 , and the plurality of guide plates 241 are arranged at intervals along the second direction Y to improve the guiding effect.

[0072] Please continue to refer to Figure 2 The box sealing device also includes a material shaping mechanism 60, which is arranged upstream of the box buckle mechanism 20 and includes a third driving member and a third pressure plate connected to the third driving member. The third pressure plate is arranged on one side of the transportation mechanism 10 along the third direction Z. The third driving member drives the third pressure plate to be movably arranged along the third direction Z. The third pressure plate is used to press down the material in the packaging box 30 along the third direction Z.

[0073] The material shaping mechanism 60 is arranged upstream of the box buckle mechanism 20, and is used to press the material in the packaging box 30 to the ideal material placement position of the packaging box 30 before the packaging box 30 is transported to the box buckle mechanism 20, so as to prevent the material from protruding and affecting the sealing effect. In the material shaping mechanism 60, the third driving member can be a linear driving structure or a rotary driving structure, which is not limited in this embodiment. When the third driving member is a rotary driving structure, the third driving member can rotate along the fifth axis, and the fifth axis can extend along the first direction X and the second direction Y, thereby driving the third pressing plate to move along the third direction Z. The third pressing plate can be arranged relative to the transport mechanism 10 along the third direction Z. When the transport mechanism 10 drives the packaging box 30 to move to the material shaping mechanism 60, the third pressing plate is driven by the third driving member to move toward the side close to the transport mechanism 10 along the third direction Z, so that the third pressing plate can press the material in the packaging box 30 down to the ideal material placement position of the packaging box 30.

[0074] Please continue to refer to Figure 5 According to the first aspect of the embodiment of the present application, the transport mechanism 10 includes a transport component 11 and a limiting component 12, the material placement position is set on the transport component 11, the limiting component 12 includes a first limiting plate 121 and a second limiting plate 122 set on the transport component 11, the first limiting plate 121 and the second limiting plate 122 are relatively arranged along a first direction X, the material placement position is set between the first limiting plate 121 and the second limiting plate 122, the first limiting plate 121 and the second limiting plate 122 are used to clamp the packaging box 30 along the first direction X, and the first direction X is the transport direction of the transport component 11.

[0075] In this embodiment, the transport component 11 is used to transport the packaging box 30. In the limiting component 12, the first limiting plate 121 and the second limiting plate 122 are both arranged on the transport component 11, and are arranged on opposite sides of the material placement position along the first direction X. A second clamping space can be formed between the first limiting plate 121 and the second limiting plate 122 to clamp the packaging box 30, thereby limiting the packaging box 30 along the first direction X to prevent the packaging box 30 from moving.

[0076] It is understandable that the pre-folding mechanism 40 can be arranged near the first limiting plate 121, and the buckle forming mechanism 50 can be arranged near the second limiting plate 122. Optionally, the second limiting plate 122 can include a sixth sub-plate and a seventh sub-plate arranged in sequence along the third direction Z, the sixth sub-plate is located between the seventh sub-plate and the transport mechanism 10, and the seventh sub-plate can be bent in the first direction X toward the direction close to the first limiting plate 121. When the second driving member 52 of the buckle forming mechanism 50 drives the third sub-plate 513 to push the portion of the box body 32 corresponding to the buckle 34 from the inside of the box body 32 along the first direction X to bend toward the side away from the pre-folding mechanism 40, the sixth sub-plate and the seventh sub-plate can shape the buckle 34 so that the cross section of the buckle 34 along the first direction X is approximately triangular, which is convenient for plugging into the socket of the top cover 31.

[0077] like Figure 6 As shown, according to the first aspect of the embodiment of the present application, the carton sealing device also includes an adjusting mechanism 70, the adjusting mechanism 70 includes a fifth driving member 71, a first rotating shaft 72, a first connecting member 73 and a second connecting member 74, the fifth driving member 71 is connected to the first rotating shaft 72, and is used to drive the first rotating shaft 72 to rotate, the first rotating shaft 72 extends along the first direction X, and is threadedly connected to the first connecting member 73 and the second connecting member 74, respectively, and the thread rotation direction of the first connecting member 73 is opposite to the thread rotation direction of the second connecting member 74, the first connecting member 73 is connected to the first limit plate 121, and the second connecting member 74 is connected to the second limit plate 122.

[0078] The adjustment mechanism 70 is used to adjust the position of the first limit plate 121 and the second limit plate 122 along the first direction X, so as to adjust the size of the second clamping space between the first limit plate 121 and the second limit plate 122 along the first direction X, so that the sealing device can be applied to packaging boxes 30 of more sizes, thereby improving the scope of application of the sealing device. In the adjustment mechanism 70, the fifth driving member 71 can be a rotating drive structure such as a rotating motor and a rotating cylinder, or the fifth driving member 71 can also be a manual rotating component such as a rotating handle and a ratchet wrench, which is not limited in this embodiment. The fifth driving member 71 is connected to the first rotating shaft 72, thereby driving the first rotating shaft 72 to rotate. Since the first rotating shaft 72 extends along the first direction X, and the first connecting member 73 and the second connecting member 74 are both threadedly connected to the first rotating shaft 72, when the first rotating shaft 72 rotates, the first connecting member 73 and the second connecting member 74 can move along the first direction X driven by the first rotating shaft 72. Since the thread rotation direction of the first connecting member 73 is opposite to that of the second connecting member 74, the first connecting member 73 and the second connecting member 74 move in opposite directions under the drive of the first rotating shaft 72. That is to say, when the first connecting member 73 moves along the first direction X toward the side away from the second connecting member 74, the second connecting member 74 simultaneously moves along the first direction X toward the direction away from the first connecting member 73; when the first connecting member 73 moves along the first direction X toward the side close to the second connecting member 74, the second connecting member 74 simultaneously moves along the first direction X toward the direction close to the first connecting member 73. Therefore, by connecting the first limiting plate 121 with the first connecting member 73 and connecting the second limiting plate 122 with the second connecting member 74, the first limiting plate 121 and the second limiting portion can be driven to move along the first direction X in a direction close to or away from each other, thereby realizing the adjustment of the size of the second clamping space between the first limiting plate 121 and the second limiting plate 122 along the first direction X.

[0079] It can be understood that the thread rotation direction of the first connecting member 73 refers to the spiral direction of the thread between the first connecting member 73 and the first rotating shaft 72 , and the thread rotation direction of the second connecting member 74 refers to the spiral direction of the thread between the second connecting member 74 and the first rotating shaft 72 .

[0080] Please refer to Figure 7 , and / or, the transport component 11 includes a transport member 111 and a plurality of clamping members 112 arranged on the transport member 111 at intervals along the second direction Y, the clamping member 112 includes a first clamping block 113 and a second clamping block 114 arranged at intervals along the second direction Y, and the first clamping block 113 and the second clamping block 114 are used to clamp the packaging box 30 along the second direction Y.

[0081] In the transport component 11, the transport member 111 is used to transport the packaging box 30 along the first direction X, and the number of the clamping members 112 is multiple, and the multiple clamping members 112 are arranged on the transport member 111 at intervals along the second direction Y. When the transport member 111 transports multiple packaging boxes 30 synchronously, each clamping member 112 can clamp one packaging box 30 along the second direction Y to limit the packaging box 30 along the second direction Y. In the clamping member 112, the first clamping block 113 and the second clamping block 114 are arranged at intervals along the second direction Y, so that a third clamping space can be formed between the first clamping block 113 and the second clamping block 114 for clamping the packaging box 30 along the second direction Y.

[0082] Optionally, the first clamp block 113 and / or the second clamp block 114 may include a clamp block body and an elastic buffer. The elastic buffer of the first clamp block 113 is arranged on the side of the corresponding clamp block body facing the second clamp block 114 along the second direction Y, and the elastic buffer of the second clamp block 114 is arranged on the side of the corresponding clamp block body facing the first clamp block 113 along the second direction Y. Therefore, in the process of clamping the packaging box 30 along the second direction Y by the first clamp block 113 and the second clamp block 114, the packaging box 30 can apply pressure to the elastic buffer, causing the elastic buffer to shrink, so as to increase the size of the third clamping space along the second direction Y, thereby facilitating the installation of the packaging box 30. At the same time, the elastic buffer can play a certain buffering role between the clamp block body and the packaging box 30 to avoid damage to the packaging box 30.

[0083] Furthermore, the elastic buffer may include a second rotating shaft, a buffer pad and a spring. The second rotating shaft can be connected to the clamp body and extend along the first direction X. The buffer pad is rotatably set on the second rotating shaft. The spring is connected to the buffer pad and is located between the buffer and the clamp body. Therefore, when the packaging box 30 is placed in the third clamping space, the box body 32 of the packaging box 30 can apply pressure to the buffer pad to compress the spring, thereby increasing the size of the third clamping space along the second direction Y, which is convenient for the installation of the packaging box 30, with a simple structure and high reliability.

[0084] like Figure 5 As shown, according to the first aspect of an embodiment of the present application, when the transport component 11 includes a transport member 111 and a plurality of clamping members 112, the transport member 111 includes a first transport component 115 and a second transport component 116 arranged in sequence along a first direction X, a first clamping block 113 is arranged on the first transport component 115, and a second clamping block 114 is arranged on the second transport component 116.

[0085] The first transport component 115 and / or the second transport component 116 can be any one of a roller conveyor line, a chain plate conveyor line, a belt conveyor line, a flat top chain conveyor line, a flexible chain plate conveyor line, a double speed chain conveyor line and a mesh belt conveyor line.

[0086] In this embodiment, the transport member 111 includes a first transport component 115 and a second transport component 116 which are arranged in sequence along the first direction X, so that the packaging box 30 can be driven to move along the second direction Y by the first transport component 115 and the second transport component 116. Moreover, since the first clamping block 113 is arranged on the first transport component 115 and the second clamping block 114 is arranged on the second transport component 116, the distance between the first clamping block 113 and the second clamping block 114 along the second direction Y can be adjusted by controlling the running speed of the first transport component 115 and the second transport component 116, thereby adjusting the size of the third clamping space between the first clamping block 113 and the second clamping block 114 along the second direction Y, so as to clamp the packaging box 30 into the third clamping space.

[0087] It can be understood that when the running speed of the first transport component 115 is equal to the running speed of the second transport component 116, the distance between the first clamping block 113 and the second clamping block 114 along the second direction Y is constant, and the size of the third clamping space along the third direction Z is constant; when the running speed of the first transport component 115 is greater than the running speed of the second transport component 116, if the first clamping block 113 is located upstream of the second clamping block 114 along the second direction Y, the distance between the first clamping block 113 and the second clamping block 114 along the second direction Y is continuously reduced, and if the first clamping block 113 is located upstream of the second clamping block 114 along the second direction Y, the distance between the first clamping block 113 and the second clamping block 114 along the second direction Y is continuously reduced. If the first clamp block 113 is located downstream of the second clamp block 114, the distance between the first clamp block 113 and the second clamp block 114 along the second direction Y will continue to increase; when the running speed of the first transport component 115 is less than the running speed of the first transport component 115, if the first clamp block 113 is located upstream of the second clamp block 114 along the second direction Y, the distance between the first clamp block 113 and the second clamp block 114 along the second direction Y will continue to increase; if the first clamp block 113 is located downstream of the second clamp block 114 along the second direction Y, the distance between the first clamp block 113 and the second clamp block 114 along the second direction Y will continue to decrease.

[0088] Taking the example that the first clamping block 113 is located upstream of the second clamping block 114 along the second direction Y, in the process of clamping the packaging box 30 to the third clamping space, the running speed of the second transport component 116 can be controlled to be greater than the running speed of the first transport component 115, so that the distance between the first clamping block 113 and the second clamping block 114 along the second direction Y is increased, thereby increasing the size of the third clamping space along the second direction Y, so as to facilitate placing the packaging box 30 in the clamping space. When the packaging box 30 is placed in the clamping space, the running speed of the first transport component 115 can be increased. And reduce the running speed of the second transport component 116 to shorten the distance between the first clamp block 113 and the second clamp block 114 along the second direction Y, thereby reducing the size of the third clamping space along the second direction Y, so that the first clamp block 113 and the second clamp block 114 can clamp the packaging box 30 along the second direction Y, and then control the running speed of the first transport component 115 to be equal to the running speed of the second transport component 116, so that the distance between the first clamp block 113 and the second clamp block 114 along the second direction Y is constant, so that the packaging box 30 can be continuously clamped in the third clamping space.

[0089] Optionally, in the transport member 111, the number of the second transport components 116 can be two, the first transport component 115 can be arranged between the two second transport components 116 along the first direction X, the number of the second clamping blocks 114 in each clamping member 112 can be two, the two second clamping blocks 114 are arranged one-to-one on the two second transport components 116, and the distances between the two clamping blocks and the first clamping block 113 along the second direction Y are equal, so that the packaging box 30 is clamped by the first clamping block 113 and the two second clamping blocks 114, and the reliability of clamping can be improved.
