In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0042] like Figure 1-Figure 6 As shown, the embodiment of the present invention first provides a fixing mechanism 1 for a packaging box, which is suitable for a packaging box 100 that needs to fix or lock a box body 101 and a cover body 102. In this embodiment, a four-opening box is used as an example for description. Figure 7 and Figure 8 As shown, the four-open box includes a box body 101 and a cover body 102, the box body 101 includes two first side panels 1011 arranged oppositely in a first direction (X direction) and two second side panels 1012 arranged oppositely in a second direction (Y direction), and the first side panels 1011 and the second side panels 1012 are separated from each other. The first direction can be the length direction of the four-open box, and the second direction is the width direction of the four-open box, or vice versa. The first direction and the second direction are perpendicular to each other and are both perpendicular to the height direction of the four-open box. The cover body 102 includes eight adapter side panels connected to each other, namely two first adapter plates 1021, two second adapter plates 1022, and four connecting adapter plates 1023. Among them, the first adapter plate 1021 and the second adapter plate 1022 correspond to the positions of the first side panel 1011 and the second side panel 1012, respectively, and the connecting adapter plate 1023 is used to connect the adjacent first adapter plates 1021 and the second adapter plates 1022. After the bottle is placed in the box body 101, the cover body 102 is plugged into the top of the box body 101 for sealing, and then the box body 101 and the cover body 102 are fixed together. The box body 101 and the cover body 102 are connected and fixed by fixing parts or connectors, which are generally fixed and operated manually, resulting in low box packing efficiency, high labor cost, and high labor intensity of the packaging box 100.

[0043] The fixing mechanism 1 of the packaging box provided in the embodiment of the present invention is used for automatically grabbing the fixing member or the connecting member to fix the box body 101 and the cover body 102 of the packaging box 100, wherein the fixing member or the connecting member may be a buckle, and the box body through hole 1013 may be pre-set on the first side plate 1011 and the second side plate 1012, respectively, and the cover body through hole 1024 corresponding to the box body through hole 1013 may be set on the first adapter plate 1021 and the second adapter plate 1022 as an adaption structure. In other embodiments, the fixing member may also be other structural members such as an elastic pin, etc. This embodiment takes the buckle as the fixing member and inserts the fixing member into the box body through hole 1013 and the cover body through hole 1024 as an example to exemplarily illustrate the fixing mechanism 1 of the packaging box.

[0044] The fixing mechanism 1 of the packaging box provided in the embodiment of the present invention includes a mounting frame 11, a first driving member 12 and a gripping head 13, wherein the first driving member 12 is arranged on the mounting frame 11; the gripping head 13 includes a swinging driving member 131 and a gripping hand 132, wherein the swinging driving member 131 is arranged at the output end of the first driving member 12, and the gripping hand 132 is arranged at the output end of the swinging driving member 131. When the first driving member 12 drives the swinging driving member 131 to the first moving position, the swinging driving member 131 drives the gripping hand 132 to the first swing angle position to grip the fixing member, and when the swinging driving member 131 drives the gripping hand 132 to the second swing angle position, the first driving member 12 drives the swinging driving member 131 to the second moving position so that the fixing member is simultaneously inserted into the box body 101 and the cover body 102 to fix the box body 101 and the cover body 102.

[0045] like Figure 2-Figure 6 The fixing mechanism 1 of the packaging box provided by the present invention can realize the switching of the gripper 132 between the first moving position and the second moving position, and the switching between the first swing angle position and the second swing angle position of the gripper 132 by setting the first driving member 12 and the swing driving member 131, so that after the first driving member 12 drives the gripper 132 to grasp the fixing member at the first moving position and the first swing angle position, the gripper 132 is driven to the second swing angle position and the second moving position to clamp the fixing member into the box body 101 and the cover body 102 of the packaging box 100, thereby realizing automatic fixing of the box body 101 and the cover body 102 by the fixing member without manual intervention, thereby improving the packaging efficiency of the packaging box 100 and reducing the packaging cost.

[0046] like Figure 2As shown, along the length direction (X direction) of the mounting frame 11, a plurality of first driving members 12 are sequentially arranged at intervals on the mounting frame 11, so that the simultaneous fixing of a plurality of packaging boxes 100 along the X direction can be realized, thereby improving the packaging efficiency of the packaging box 100. Further, along the second direction (Y direction), the gripping head 13 is arranged in pairs, so that the two groups of first side plates 1011 and the first adapter plate 1021 arranged at the relative position of the packaging box 100 are easily fixed at the same time, and the second side plate 1012 and the second adapter plate 1022 arranged at the relative position are fixed at the same time, and the installation efficiency is high. The two gripping heads 13 arranged in pairs simultaneously and synchronously fix the packaging box 100, and the fixing member generates a relative force when contacting the packaging box 100, which is conducive to the stable fixing of the packaging box 100. The two gripping heads 13 arranged in pairs can be driven and controlled by two single-output first driving members 12 respectively, or can be controlled by a dual-output first driving member 12, which is specifically selected according to the actual structure.

[0047] In some embodiments, the gripping head 13 also includes a swinging mounting member 133 and a swinging connecting member 134. The swinging mounting member 133 is arranged at the output end of the first driving member 12, and the fixed end of the swinging driving member 131 is rotatably arranged on the swinging mounting member 133; the swinging connecting member 134 is rotatably connected to the swinging mounting member 133, and the movable end of the swinging driving member 131 is rotatably connected to the swinging connecting member 134. The gripper 132 is arranged on the swinging connecting member 134, and the telescopic movement of the movable end of the swinging driving member 131 can drive the swinging connecting member 134 to rotate, so that the gripper 132 can switch between the first swing angle position and the second swing angle position.

[0048] like Figure 5 and Figure 6 As shown, the swing driving member 131 takes a cylinder as an example, and the two ends of the swing driving member 131 are respectively hinged to the swing mounting member 133 and the swing connecting member 134. When the output end of the swing driving member 131 telescopically moves, the swing connecting member 134 rotates relative to the swing mounting member 133, and then the swing connecting member 134 can drive the gripper 132 to switch between the first swing angle position and the second swing angle position. In other embodiments, the swing driving member 131 can also be a motor, such as a motor, and the swing connecting member 134 is connected to the swing mounting member 133 through a rotating shaft. The output shaft of the motor directly drives the rotating shaft to rotate, and the driving control of the swing connecting member 134 between the first swing angle position and the second swing angle position can also be realized. It can be understood that the swing mounting member 133 and the swing driving member 131 are respectively hinged at two different positions on the swing connecting member 134 to facilitate the rotational movement of the swing connecting member 134. Preferably, the swing driving member 131 is coaxially arranged with the gripper 132 for easy positioning.

[0049] In some embodiments, the gripping head 13 further includes a limit member 136 , which is disposed on one end of the swing mounting member 133 close to the swing connecting member 134 . When the gripping hand 132 rotates from the second swing angle position to the first swing angle position, the swing connecting member 134 can abut against the limit member 136 .

[0050] like Figure 6 The limiter 136 is arranged on the swing mounting member 133, and is used to limit the rotation angle of the swing connector 134, and can limit the swing connector 134 to rotate in one direction. When the gripper 132 is located at the first swing angle position, the swing connector 134 abuts against the limiter 136, preventing the swing connector 134 from continuing to rotate, which is conducive to limiting the swing angle position of the gripper 132, so as to accurately grasp the fixed member. The limiter 136 allows the swing connector 134 to rotate in one direction from the first swing angle position to the second swing angle position, thereby allowing the two grippers 13 arranged in pairs to rotate and fix relative to each other, thereby improving the packaging efficiency.

[0051] In some embodiments, the gripper 132 includes a suction cup. The gripper 132 absorbs the fixing member through vacuum adsorption, which is conducive to grasping and releasing control, and the suction cup is made of elastic material, which can avoid bumping and damaging the fixing member and the packaging box 100. As needed, the gripper 132 can be a plurality of suction cups arranged on the swing connector 134, which are used for multiple fixing members to fix the packaging box 100 at the same time, and perform multi-point fixation. In other embodiments, the gripper 132 can also be a structure with grasping and releasing functions such as a clamp, not limited to a suction cup.

[0052] In some embodiments, the gripping head 13 further includes a protective member 135 , which is fixed on the swing connecting member 134 , and the protective member 135 is provided with an accommodating space for accommodating at least a portion of the gripping hand 132 .

[0053] like Figure 6 As shown, the protective member 135 is disposed at the end of the swing connector 134. The protective member 135 is provided with a receiving space and a through hole communicating with the receiving space. The suction cup is passed through the through hole. At least part of the structure of the suction cup is located in the receiving space to prevent the suction cup from being damaged. Specifically, the protective member 135 is a shell structure member, and has the same structural size as the end of the swing connector 134. The protective member 135 is detachably mounted on the swing connector 134.

[0054] In some embodiments, the first driving member 12 includes a double-headed cylinder, and two movable ends of the double-headed cylinder are respectively connected to a gripping head 13, so that the two gripping heads 13 can move toward or away from each other along the second direction.

[0055] like Figure 4As shown, the first driving member 12 adopts a double-headed cylinder, and two gripping heads 13 can be installed at the same time, so that the movement of the two gripping heads 13 can be easily controlled synchronously, so as to simultaneously fix the opposite sides of the packaging box 100, improve efficiency and easily control the symmetry during fixation, and ensure the stable fixation of the packaging box 100. Of course, in other embodiments, the first driving member 12 also adopts a double-output oil cylinder or a double-output motor to achieve the synchronous movement of the two gripping heads 13. The double-headed cylinder can also be formed by combining two single-output cylinders to form a coaxial drive mechanism. The first driving member 12 and the swing driving member 131 are preferably linear drive mechanisms such as cylinders or oil cylinders, which are easy to control and install.

[0056] In some embodiments, the fixing mechanism 1 of the packaging box also includes a connecting rod assembly 14, which is hinged to the mounting frame 11. A plurality of first driving members 12 are arranged on the connecting rod assembly 14. The connecting rod assembly 14 can telescopically move along a first direction to drive the plurality of first driving members 12 to move closer to or away from each other along the first direction, and the first direction is perpendicular to the second direction.

[0057] like Figure 2 and Figure 3 As shown, the connecting rod assembly 14 is arranged along the length direction of the mounting frame 11, and multiple first driving members 12 can be installed in sequence to move synchronously, so as to simultaneously fix and package multiple packaging boxes 100. One end of the connecting rod assembly 14 is hinged to the mounting frame 11, and when the connecting rod assembly 14 moves telescopically, the other end drives the multiple first driving members 12 to move closer or farther from each other to adapt the position of the packaging box 100 and the position of the fixing member. The telescopic movement of the connecting rod assembly 14 can be controlled by mechanical transmission, or a second driving member (not shown in the figure) can be set for drive control, and the second driving member is configured to drive the connecting rod assembly 14 to move telescopically. The second driving member can be a cylinder, an oil cylinder, a motor or other mechanism. The second driving member can be set at any end of the connecting rod assembly 14 on the mounting frame 11. By pulling the first driving member 12 or the connecting rod assembly 14 at the end to move by the first driving member 12, the connecting rod assembly 14 can be driven to extend and retract to enable the remaining first driving members 12 to move. By setting up the connecting rod assembly 14, the synchronous movement of multiple first driving members 12 can be achieved through only one second driving member, thereby improving movement efficiency and reducing equipment costs.

[0058] In some embodiments, a plurality of second driving members may be provided, and the plurality of second driving members are provided one by one with the plurality of first driving members 12 to respectively drive the first driving members 12 to move along the first direction, so that the gripper 132 can move along the second direction at the first moving position and the second moving position to perform a fixing operation of the packaging box 100. When there are a plurality of second driving members, the connecting rod assembly 14 may be omitted.

[0059] In some embodiments, the connecting rod assembly 14 includes multiple connecting rod units, each connecting rod unit includes two connecting rods 141 cross-hinged at an intersection, the corresponding connecting rods 141 of two adjacent connecting rod units are hinged, and a first driving member 12 is hinged at the intersection of each connecting rod unit.

[0060] like Figure 3 As shown, each connecting rod unit includes two cross-hinged connecting rods 141 of equal length, the hinge position of the two connecting rods 141 is the intersection, the first driving member 12 is hinged at the intersection, and the two connecting rods 141 drive the position of the first driving member 12 to move when they rotate relative to each other. In two adjacent connecting rod units, the ends of the two connecting rods 141 in one connecting rod unit are respectively hinged to the head ends of the two connecting rods 141 in the other connecting rod unit, so as to realize the hinged series connection of multiple connecting rod units. Through this structure, when the connecting rod assembly 14 is extended or retracted, it can drive multiple first driving members 12 to move closer to or farther from each other, so as to realize synchronous movement control.

[0061] In some embodiments, the fixing mechanism 1 of the packaging box also includes a slide rail 15 and multiple sliders 16. The slide rail 15 is arranged on the mounting frame 11, and the slide rail 15 is arranged along the first direction; the multiple sliders 16 are all slidably connected to the slide rail 15, and the multiple first driving members 12 are connected to the multiple sliders 16 one by one.

[0062] like Figure 4 As shown, in order to reduce the load of the first driving members 12 on the connecting rod assembly 14, the first driving members 12 are slidably mounted on the guide rails on the mounting frame 11 through the slider 16, so that the weight of the first driving members 12 can be carried by the mounting frame 11. In order to facilitate the installation and sliding of the first driving members 12, in this embodiment, the first driving member 12 is firstly mounted on the sliding mounting member 121, and then hinged with the connecting rod assembly 14 through the sliding mounting member 121. The sliding connecting members 122 are symmetrically arranged on both sides of the sliding mounting member 121, and the sliding connecting members 122 are fixedly connected to the slider 16. The slide rails 15 are symmetrically arranged on both sides of the mounting frame 11 along the Y direction, so that both ends of the first driving member 12 along the Y direction are slidably mounted on the mounting frame 11, ensuring the stable installation of the first driving member 12.

[0063] The embodiment of the present invention further provides a cartoning machine, which is used to load a bottle into a packaging box 100 and fix and package it. The cartoning machine includes a fixing part conveying line 4 and a fixing mechanism 1 of the packaging box provided by the embodiment of the present invention. The fixing part conveying line 4 is used to convey the fixing part to a first moving position along a first direction, and the gripping head 13 of the fixing mechanism 1 of the packaging box can move to the first moving position along a second direction to grab the fixing part. In this way, an automated packaging process of the packaging box 100 is realized, and the packaging efficiency is high.

[0064] In some embodiments, the cartoning machine further comprises a frame 2, on which two fixing mechanisms 1 for packaging boxes are provided along a first direction, a rotating mechanism 5 is provided between the fixing mechanisms 1 for the two packaging boxes, and a fixing member conveyor line 4 is provided on both sides of the fixing mechanisms 1 for the packaging boxes along a second direction.

[0065] like Figure 1 As shown, a box loading mechanism 3, a fixing mechanism 1 for a first packaging box, a rotating mechanism 5 and a fixing mechanism 1 for a second packaging box are sequentially arranged on the frame 2 along a first direction, wherein the box loading mechanism 3 is used to put the bottle body into the box body 101 and cover the cover body 102 on the box body 101, and the fixing part conveying line 4 is arranged on both sides of the fixing mechanism 1 for the first packaging box and the fixing mechanism 1 for the second packaging box, so that the gripping head 13 can grip the fixing parts for fixing along both sides of the second direction respectively. The fixing mechanism 1 of the first packaging box grabs a pair of fixing parts and fixes the relatively arranged first side plate 1011 and the first adapter plate 1021. After the rotating mechanism 5 rotates the packaging box 100 90°, the fixing mechanism 1 of the second packaging box grabs a pair of fixing parts and fixes the relatively arranged second side plate 1012 and the second adapter plate 1022. When the fixing parts are snap buckles, when the fixing parts move from the second swing angle position to the second moving position along the second direction, the fixing parts can be inserted into the box body through hole 1013 and the cover body through hole 1024 to achieve snap-fit ​​fixation, thereby realizing automatic fixed packaging of the packaging box 100, with high packaging efficiency and saving labor costs.
