Without departing from the design spirit of the application, various modifications made by those of ordinary skill in the art to the technical solutions of the application And improvements should fall within the scope of protection determined by the claims of this application.

As shown in Figures 1-3, the first implementation of this application proposes a box opening device, which includes:

Box embryo grasping unit 3 that can grasp box embryos,

The box opening unit 4 includes a side pushing member 41 provided on one side of the box blank grasping unit 3, and is connected with the side pushing member 41 to drive the side pushing member 41 to approach the box blank grasping Take the third driving member 42 that is displaced in the direction of the unit 3 in multiple stages.

As shown in Figure 6, the box blank 101 when the packaging box is not unfolded, the panel (main panel 1011 and side panel 1012) and the box cover (main cover 1013 and side cover 1014) are all folded with each other, and the main cover 1013 and the side folded in dislocation The covers 1014 are attached to each other, and there is a gap 1015 between the adjacent main cover 1013 and the side cover 1014. The side pushing member 41 is driven by the third driving member 42 to move in a direction close to the box blank grasping unit 3, and the side panel 1012 or the edge of the side panel 1012 of the box blank is pushed multiple times by the side pushing member 41, As a result, the box blank 101 undergoes multiple preset deformations, so that the box blank 101 is gradually opened, which effectively prevents the box blank 101 from being damaged due to uneven stress transmission during a deformation process. At the same time, compared to opening the box by rotating or inflating, the structure is simpler, and it is easy to control and maintain.

As a further optimization of this embodiment, as shown in FIG. 7, the side pusher 41 includes a side pusher body 411, and is arranged at one end of the side pusher body 411 and faces away from the box embryo grasping unit 3 direction A curved arc curved portion 412. The curvature of the curved portion 412 can be set as required. After the box embryo grasping unit 3 grabs the box embryo 101, it moves according to a preset path. The curved portion 412 first touches the box embryo 101, and the box embryo 101 pushes the side of the body 411 When moving in the direction, the place where the box blank 101 contacts the curved portion 412 gradually moves to the side pusher body 411. Due to the arc-shaped arrangement of the curved portion 412, the force on the side panel 1012 of the box blank transitions smoothly and gradually becomes larger. The embryo grasping unit 3 cooperates with the third driving member 42 to further ensure the smooth transition of the force received during the initial opening of the box embryo 101 and gradually increase, which effectively prevents the side pushing member 41 from performing the initial opening of the box 101 due to lack of force. Even or change too quickly, causing damage to the box embryo.

Optionally, the box embryo grasping unit 3 is two sets of suction cups arranged at intervals, and the side pusher 41 is arranged in the middle of the two sets of suction cups, so as to ensure that the position where the side pusher 41 applies force is at The main part of the box blank 101, that is, the side panel 1012 part, is not in the box cover part. At the same time, the use of suction cups can be adapted to box blanks of different sizes, without structural adjustment due to different box blank sizes, only the height of the position of the suction cup relative to the box blank needs to be adjusted.

At this time, if the side pusher 41 When a pushing force is applied to the box blank 101 from the side panel 1012 or the edge of the side panel, the box blank 101 will not open, but will be further tightened. After the second limiting member 43 is inserted into the gap 1015 between adjacent box covers, the box cover opposite to the gap 1015 can be blocked, and the part that can pass through the second limiting member 43 will continue to move according to the preset path. As a result, the box blank 101 will deform in the direction of separation. At this time, when the side pusher 41 applies a force to the box blank 101 from one side, it can ensure that the box blank 101 is deformed to the opened state. The box embryo 101 is driven by the box embryo grasping unit 3 to advance, and the second limiting member 43 is located in the gap 1015 of the two box covers opposite to the box embryo grasping unit 3, so it is opposite to the box embryo grasping unit 3. The two box covers can pass through the second limiting member 43 without obstacles, but the two box covers on the other side will be blocked by the second limiting member 43, thereby further opening the box blank 101. It should be noted here that the second limiting member is preferably tapered, and can also be provided as required.

Further, the box opening device further includes a ninth drive connected to the second limiting member 43 to drive the second limiting member 43 to move away from and/or close to the box embryo grasping unit 3 431, to control its extension or retraction when needed to prevent scratching the box embryo. The ninth driving member 431 can drive the second limiting member 43 to move away from the box embryo 101 when the box embryo 101 moves to the preset position, stop the limiting effect on the box embryo 101, and prevent the If the box embryo 101 is opened too large to cause damage, it can also prevent the second limiting member 43 from scratching the box embryo 101. In addition, it should be noted that the ninth driving member 431 may also be configured to drive the second limiting member 43 to move closer to the box embryo grasping unit 3. At this time, the second The initial position of the limiting member 43 can be set at a position where the box blank 101 cannot touch on the preset path, and the second limiting member 43 can be driven to move to the gap 1015 when the box blank 101 moves to the preset position. It can be set as required. The ninth driving member can be a driving element such as an electric cylinder, an air cylinder, or a hydraulic cylinder.

The box compartment frame 12 is provided with a accommodating space The convex first limiting member 15 has an adjustable protrusion length, and the first driving member 14 is connected to the first moving member 13. Optionally, as shown in Figures 1 and 3, a box bottom plate 16 for supporting the bottom of the box blank is also provided between the two box warehouse side plates 11, and a first guide rail is also provided between the two box warehouse side plates 11 17. The first moving member 13 can move along the first guide rail 17 under the pushing of the first driving member 14. The first driving part 14 can provide a preset pressure or thrust to the first moving part 13, so that the box blank can be pre-pressed between the first moving part 13 and the first limiting part 15. When one of the box blanks is removed , So that the pre-pressure applied by the first moving member to the box blank is reduced or disappeared, and the preset pressure or thrust provided by the first driving member 14 to the first moving member 13 makes the first moving member 13 continue to pre-press the loose box blank, A certain pre-pressure is still maintained between multiple box embryos. The multiple box blanks placed between the two box compartment side plates 11 have one side in contact with the first moving member 13 and the other side in contact with the first limiting member 15 through the first driving member 14 and the first moving With the arrangement of the member 13, the first driving member 14 provides a preset pressure or thrust to the first moving member 13, and the first moving member 13 can continuously apply the preset pressure to the box blank according to the needs, passing the first limiting member 15 To limit the box blank, the first limiting member 15 cooperates with the first driving member 14 and the first moving member 13 so that the box blank placed between the two box warehouse side plates 11 is in a balanced state, and One box blank is taken out, and the rest of the box blanks will automatically advance toward the first limiting member 15 under the pressure or thrust of the first moving member 13. At the same time, by adjusting the protruding length of the first limiting member 15 and the pressure exerted by the first driving member 14, it can be adapted to box blanks of different materials and different sizes, with a wider application range and simple structure.

10-12, a second embodiment of the present application proposes a packaging machine, including the box opening device described above, and further including: a box transport unit 2 for transporting boxes;

The box warehouse unit 1 is used to place a box blank;

The box embryo grasping unit 3 is arranged between the box warehouse unit 1 and the box transport unit 2, and is used to grasp the packaging box and place it on the box transport unit 2;

The box opening unit 4 is arranged between the box warehouse unit 1 and the box body transport unit 2 for opening the box blank;

Material grabbing unit 5, used for grabbing materials and placing them in the packing box;

The box sealing unit 6 is arranged between the box opening unit 4 and the box transport unit 2 for packaging the packaging box.

In the packaging machine described in this application, the box warehouse unit 1 is used to place the box embryos, the box embryo grasping unit 3 takes the box embryos out of the box warehouse unit 1, and the box embryo is opened by the box opening unit 4, and the box embryo grasping unit 3 Put the opened packaging box on the box transport unit 2. The box transport unit 2 transports the box according to the preset trajectory. The material grab unit 5 cooperates with the box transport unit 2 to grab the material from the preset position and The materials are placed in the packaging box, and then the box sealing unit 6 bends the box cover and seals the box with glue, thereby completing the entire packaging process without manual operation and realizing automated and streamlined packaging.

As shown in Figure 13, it is the box sealing unit 6 of the packaging machine, which can be used for the glue seal on the top of the packaging box, folding the box cover of the packaging box, and fixing the folded box cover with tape to complete the packaging of the top of the packaging box.

In order to stabilize the materials packaged in the packaging box and prevent adjacent materials in the packaging box from colliding with each other and being damaged, it is usually necessary to place a middle partition in the packaging box to separate and position the packaged materials and to prevent them from being damaged. The role of shock absorption. As shown in Figure 14, the horizontal partition 2011 and the vertical partition 2012 of the unfolded center partition 201 are perpendicular to each other, but the horizontal partition 2011 and the vertical partition 2012 of the unexpanded center partition 201 are folded each other and placed in the packing box. The horizontal partition 2011 and the vertical partition 2012 need to be expanded before. Therefore, further, as shown in Figs. 15 and 16, the packaging machine provided by the present application further includes a central partition unfolding unit 7. The central partition unfolding unit 7 includes a first base plate 71, at least one of which is connected to the first base plate. The first pressing member 72 connected to the 71 has at least one first grabbing member 73 connected to the first base plate 71 through a first rotating member 74. Here, the first pressing member 72 and the first grabbing member 73 are preferably arranged perpendicular to or similar to each other, wherein the first pressing member 72 and the first grabbing member 73 can be selected according to needs, especially the first pressing member 72 can choose a circular plate or other similar structure, which can apply force to the central partition more evenly, and the first grabbing member can choose a pneumatic suction cup. The first rotating member 74 is preferably a rotating cylinder or a rotating motor, etc., which can be selected as required. Only one displacement is required here, so it is preferably a rotary cylinder, which has low cost and light weight. The first grabbing member 73 grabs the transverse partition, and the first grabbing member 73 drives the transverse partition to rotate under the drive of the first rotating member 74, so that each transverse partition is substantially perpendicular to the longitudinal partition, thereby preliminarily unfolding the mutually folded Transverse partitions and longitudinal partitions. Through the arrangement of the first pressing member 72, the first grabbing member 73, and the first rotating member 74 connected with the first grabbing member 73, the grabbing and unfolding of a longitudinal and multi-horizontal partition is realized.
