[0002] In the cigarette processing workshop, some tobacco is transported from processing sites in other areas, usually packaged in cardboard boxes with inner lining bags. Therefore, the tobacco must be unpacked and removed before use. Currently, unpacking is entirely manual. Workers use knives to cut open the sealing tape of the boxes, then turn the entire box over and remove or empty the bags of tobacco. This method is not only slow and requires workers to perform repetitive cutting over a long period, resulting in high labor costs, but it also disrupts the production line's rhythm and carries the risk of workers being injured by knives.
[0003] Therefore, there is an urgent need for an automatic box-opening device to solve the above-mentioned technical problems. Utility Model Content

[0008] An unpacking mechanism is provided at the unloading end of the conveying mechanism and located below the unloading end. The unpacking mechanism includes a clamp and a cutting tool. The cutting tool is provided on a support surface, and the clamp is located above the cutting tool. After the packaging box is detached from the conveying mechanism, the clamp can hold the packaging box so that the sealant at the bottom of the packaging box is directly opposite the main cutting edge of the cutting tool. When the clamp pushes the packaging box along a second direction, the main cutting edge can automatically cut open the sealant. The first direction is perpendicular to the second direction.
[0009] Preferably, the unpacking mechanism further includes two support seats spaced apart along a first direction, with the cutting tool disposed between the two support seats. When the clamp moves the packaging box, the support seats can support the bottom of the packaging box.
[0010] Preferably, the unpacking mechanism further includes a driving component for driving the two support seats to detach from the bottom of the packaging box, so that the bottom plate of the packaging box can be opened and the material can be dropped.
[0011] Preferably, the orientation of the main cutting edge is opposite to that of the second direction.
[0012] Preferably, the thickness of the main cutting edge gradually increases along the second direction, and guide surfaces are formed on both sides of the main cutting edge.
[0013] Preferably, the cutting tool includes a top surface that is flat, the main cutting edge is connected to the top surface, and a secondary cutting edge is formed at the connection between the guide surface and the top surface. The secondary cutting edge is used to cut the sealant between the side wall and the bottom plate of the packaging box.

The automatic box opening device includes a conveying mechanism and a box opening mechanism; the conveying mechanism is used to convey the packaging box along a first direction; the box opening mechanism is disposed at the unloading end of the conveying mechanism and is located below the unloading end. The box opening mechanism includes a clamp and a cutter. The cutter is disposed on a support surface, and the clamp is located above the cutter. After the packaging box is separated from the conveying mechanism, the clamp can hold the packaging box so that the sealant at the bottom of the packaging box is aligned with the main blade of the cutter.

[0036] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0037] like Figures 1 to 4 As shown, this utility model provides an automatic box opening device, which includes a conveying mechanism 10 and a box opening mechanism. The conveying mechanism 10 is used to convey a packaging box 100 along a first direction. The box opening mechanism is disposed at the unloading end of the conveying mechanism 10 and is located below the unloading end. The box opening mechanism includes a clamp 20 and a cutter 30. The cutter 30 is disposed on a support surface, and the clamp 20 is located above the cutter 30. After the packaging box 100 is separated from the conveying mechanism 10, the clamp 20 can clamp the packaging box 100 so that the sealant 200 at the bottom of the packaging box 100 is directly facing the main blade 31 of the cutter 30. When the clamp 20 pushes the packaging box 100 along a second direction, the main blade 31 can automatically cut open the sealant 200. The first direction is perpendicular to the second direction.
[0038] In this device, the conveying mechanism 10 can automatically transport the packaging box 100 to the clamp 20, and the clamp 20 can hold the packaging box 100 and move it in the second direction. A cutter 30 is provided below the clamp 20, and the main cutting edge 31 of the cutter 30 is facing the movement direction of the clamp 20. Therefore, when the clamp 20 holds the packaging box 100 and moves relative to the cutter 30, the main cutting edge 31 can cut the sealant 200 in the opposite direction of the packaging box 100, so that the tobacco material inside the packaging box 100 can fall automatically under the action of gravity, thus eliminating the need for manual operation, reducing labor costs, ensuring fast production of the production line, and reducing the risk of employees being cut.
[0039] Specifically, such as Figure 1 As shown, the box-opening mechanism also includes two support seats 40 spaced apart along a first direction. A cutting tool 30 is positioned between the two support seats 40. When the clamp 20 moves the packaging box 100, the support seats 40 can support the bottom of the packaging box 100. Simultaneously, as the clamp 20 pushes the packaging box 100 forward, the main cutting edge 31 cuts open the bottom sealant 200 of the packaging box 100. At this time, under the action of the support seats 40, the bottom plate of the packaging box 100 will not open rapidly, thus preventing the internal tobacco from falling out immediately and ensuring good performance.
[0040] Furthermore, in this embodiment, the unpacking mechanism also includes a driving component, which drives the two support seats 40 to detach from the bottom of the packaging box 100, so that the bottom plate of the packaging box 100 can be opened and the material can be dropped. That is, after the unpacking task of cutting the sealant 200 is completed, the clamp 20 can drag the packaging box 100 to a suitable target position. At this time, the driving component drives the two support seats 40 to separate or move downward. At this time, the bottom plate no longer receives support force, and the tobacco inside the packaging box 100 will fall under the action of gravity, thereby completing the automatic material dropping, and the material dropping will not interfere with the normal cutting of the subsequent blade 30.
[0041] It should be noted that in this embodiment, the driving component is a cylinder. Cylinders are not only simple in structure and inexpensive, but also easy to install and use, which helps to reduce the overall cost. In addition, the clamp 20 includes a telescopic component and a clamping component. The clamping component can clamp the outer wall of the packaging box 100. The telescopic component is used to drive the clamping component to move. During material unloading, the clamping component can clamp the packaging box 100 to ensure that only the internal material can fall. After unloading, the clamping component transports the empty box to the target location for recycling, and so on.
[0042] To ensure a good unboxing experience, such as Figure 2 As shown, the orientation of the main cutting edge 31 is opposite to that of the second direction. This arrangement improves cutting efficiency, allowing the main cutting edge 31 to quickly cut through the bottom sealant 200, thus ensuring a good cutting effect.
[0043] like Figure 4 As shown, the sealant 200 includes a long side 210 at the bottom and a short side 220 connected to the side wall of the packaging box 100. If only the long side 210 at the bottom is cut, the presence of the short side 220 will affect the subsequent material cutting effect. To solve this problem, as... Figures 2-4 As shown, the thickness of the main cutting edge 31 gradually increases along the second direction, and guide surfaces 32 are formed on both sides of the main cutting edge 31. In this structure, as the thickness of the main cutting edge 31 continuously increases, the guide surfaces 32 on both sides will continuously generate supporting forces on both sides during the cutting process, thereby generating a tendency to break the short side 220, and the guide surfaces 32 can also improve the smoothness of the cutting process.
[0044] However, relying solely on external support may not be enough to cause the short side 220 to break. Therefore, as Figure 2 As shown, the cutting tool 30 includes a top surface 33, which is flat. The main cutting edge 31 is connected to the top surface 33. A secondary cutting edge 34 is formed at the connection between the guide surface 32 and the top surface 33. The secondary cutting edge 34 is used to cut the sealant 200 between the side wall and the bottom plate of the packaging box 100. That is, when opening the box, the main cutting edge 31 will cut the long side 210 first. At this time, the top surface 33 is located between the bottom plate and the side wall. As the clamp 20 pushes the packaging box 100 to move continuously, the secondary cutting edge 34 gradually contacts the short side 220 and cuts the short side 220. When all the sealant 200 is destroyed, the connection between the bottom plate and the side wall is completely lost. When the support 40 is removed from the packaging box 100, the short side 220 is no longer attached to the bottom plate, and the tobacco inside will fall under the action of gravity, thus completing the opening work.
[0045] In addition, such as Figure 2 and Figure 3 As shown, the cutter 30 also includes a bottom surface 35, the width of which along the first direction is less than the width of the top surface 33 along the first direction. The top surface 33 and the bottom surface 35 are connected by an inclined side surface 36. In this structure, since the width of the top surface 33 is greater than the width of the bottom surface 35, an inclined side surface 36 (a structure that is larger at the top and smaller at the bottom) is formed. During the cutting process, the inclined side surface 36 can generate a downward component force on the bottom of the packaging box 100. This component force can drive the bottom plate to open downwards, thereby improving the opening speed and ease of opening the box, and ensuring that the bottom plate opens quickly to achieve material unloading.
[0046] like Figure 2 and Figure 3 As shown, the length of the bottom surface 35 along the second direction is less than the length of the top surface 33 along the second direction. This structure can form an inclined main cutting edge 31, thereby further improving the ease of cutting the sealant 200 and ensuring good unpacking efficiency; at the same time, this structure can also save materials, reduce manufacturing costs, and reduce the overall weight of the cutting tool 30.
[0047] like Figure 2 and Figure 3 As shown, a rounded chamfer 37 is provided at the connection between the inclined side 36 and the top surface 33, and / or a rounded chamfer 37 is provided at the connection between the inclined side 36 and the bottom surface 35. This design can prevent workers from being scratched at the connection, and can also prevent the packaging box 100 from being damaged during the cutting process, thus preventing it from being reused.
[0048] Furthermore, the tool 30 is a one-piece molded structure. This design further reduces machining difficulty, thereby lowering machining costs. Moreover, the one-piece structure also improves the structural strength of the tool 30, ensuring its service life.
[0049] Referring to the accompanying drawings, the working process of the automatic box-opening device in this embodiment is described as follows:
[0050] First, the packaging box 100 is transferred to the loading end of the conveying mechanism 10, with the bottom of the packaging box 100 facing the conveying mechanism 10. The conveying mechanism 10 then transports the packaging box 100 bottom down to the clamp 20 at the unloading end.
[0051] Secondly, the clamp 20 holds the packaging box 100 and moves it in the second direction, and the top surface 33 of the cutter 30 can be embedded between the bottom plate and the side wall. As the clamp 20 moves, all the sealant 200 (long side 210 and short side 220) is cut open.
[0052] Finally, the drive unit drives the two support seats 40 to detach from the packaging box 100, so that the tobacco inside the packaging box 100 can be smoothly discharged.
[0053] In summary, the automatic box-opening device in this embodiment can not only automatically cut the sealant 200, but also empty the tobacco inside the packaging box 100, thereby reducing labor costs, ensuring fast-paced production on the production line, and reducing the risk of scratches.
[0054] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
