Description

Technical Field

[0001] This utility model relates to the field of packaging box processing technology, and in particular to a packaging box nailing machine. Background Technology

[0002] A packaging box stapling machine is an automated device used for assembling packaging boxes. It primarily assembles unfolded packaging boxes into finished products by stapling them together after extrusion molding. The machine typically includes a conveying mechanism, a lower die, and a pressing component. The conveying mechanism transports the unfolded packaging box to the lower die, which has a forming cavity. The pressing component presses down to engage with the lower die to ensure the packaging box maintains its correct shape during assembly.

[0003] In existing packaging box nailing machines, the downward pressure of the pressing component when pressing down on the packaging box is too large and the pressing process is too abrupt, which can easily damage the packaging box. It can also cause uneven stress on the packaging box, resulting in misalignment and failure to fit with the lower mold for forming, which seriously affects the final packaging box forming effect. Utility Model Content

[0004] Therefore, it is necessary to provide a packaging box nailing machine to solve the technical problems existing in the background art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A packaging box nailing machine includes: a conveying mechanism, a lower mold, and a pressing component located above the lower mold for pressing down the packaging box. The direction from the front end of the conveying mechanism to the rear end of the conveying mechanism is the feeding direction. The conveying mechanism is used to transport the unfolded packaging box to the lower mold. The lower mold is arranged along the feeding direction and located between the conveying mechanisms. The lower mold has a forming cavity with a rectangular horizontal cross-section. The four sides of the port of the forming cavity are provided with a vertically shaped forming component with a cane-like cross-section. An elastic component that can bounce up and down is provided inside the forming cavity.

[0007] In one embodiment, the elastic component includes: a placement member and a telescopic rod, the placement member having a placement cavity, a spring being disposed within the placement cavity, one end of the spring being connected to the bottom of the placement cavity, and the other end of the spring being connected to the telescopic rod.

[0008] In one embodiment, a support plate is provided at the upper end of the telescopic rod.

[0009] In one embodiment, the four sides of the lower mold port are provided with forming surfaces that slope inward from top to bottom.

[0010] In one embodiment, a nailing mechanism is provided at each of the four corners of the lower mold, and the nailing mechanism is used to nail at the four connecting corners of the packaging box.

[0011] In one embodiment, the packaging box nailing machine further includes a support frame, and the pressing component includes a first driver and a pressing block. The first driver is mounted on the support frame and is drivenly connected to the pressing block to drive the pressing block to press down on the packaging box.

[0012] In one embodiment, the conveying mechanism includes two clamping members and two second drivers. The two clamping members are spaced apart in the left-right direction. Each second driver is driven to be connected to one of the clamping members, and the second driver drives the clamping member to move in the feeding direction.

[0013] In one embodiment, the clamping member is provided with a limiting clamp.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a packaging box nailing machine. After a packaging box with four folded edges in an unfolded state is placed on a conveying mechanism, the conveying mechanism conveys the packaging box to the lower mold. Then, the lower pressing component presses down on the middle of the packaging box and presses the packaging box into the forming cavity. At the same time, the elastic component is also pressed and slowly moves downward to absorb part of the downward pressure of the lower pressing component, so that the packaging box moves downward smoothly, making the packaging box folding and forming process stable. In this process, the four folded edges interact with the forming components on the four sides of the port of the forming cavity, so that the four folded edges contract towards the middle of the packaging box, ensuring that the packaging box is folded and formed smoothly.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments of the present invention can be combined with each other. The technical solutions of the present invention will be further described below with reference to the accompanying drawings of the embodiments. The present invention is not limited to the specific embodiments described below.

Therefore, the terms describing positional relationships in the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0025] like Figures 2-4As shown, a packaging box nailing machine includes: a conveying mechanism 10, a lower mold 20, and a pressing component 40 located above the lower mold 20 for pressing down the packaging box. The direction in which the front end of the conveying mechanism 10 moves to the rear end of the conveying mechanism 10 is defined as the feeding direction. The lower mold 20 is arranged along the feeding direction and located between the conveying mechanisms 10. The lower mold 20 has a forming cavity 21 with a rectangular horizontal cross-section. Each of the four sides of the port of the forming cavity 21 is provided with a forming component 22 with a vertical cross-section shaped like a crutch. A nailing mechanism 60 is provided at each of the four corners of the lower mold 20. An elastic component 30 that can bounce up and down is provided inside the forming cavity 21. In use, after the packaging box is placed on the conveying mechanism 10, the conveying mechanism 10 is used to convey the packaging box to the lower mold 20. Then, the pressing member 40 presses down on the middle of the packaging box and presses the packaging box into the forming cavity 21. When the pressing member 40 presses down, it also presses down on the elastic component 30. After being pressed, the elastic component 30 moves slowly downward. The elastic component 30 can absorb part of the downward pressure when the pressing member 40 presses down, so that the packaging box moves downward smoothly, ensuring the stability of the packaging box folding and forming process. In this process, the four folded edges abut against the forming members 22 on the four sides of the port of the forming cavity 21. The upper end of the cane-shaped forming member 22 has an arc-shaped part, which protrudes from the port of the forming cavity 21. The four folded edges are squeezed by the arc-shaped part and shrink towards the middle of the packaging box, ensuring that the packaging box is folded and formed smoothly. Finally, the nailing mechanism 60 nails the corners of the folded packaging box to prevent the packaging box from falling apart, thus completing the processing of the packaging box. It should be noted that the nailing mechanism 60 is a commonly used mechanism for nailing packaging boxes by those skilled in the art; therefore, its structure and working principle will not be described in detail.

[0026] Preferred, such as Figure 4As shown, the elastic component 30 includes: a placement member 31 and a telescopic rod 32. The placement member 31 is fixedly connected to the bottom of the molding cavity 21. The placement member 31 has a placement cavity 311. A spring 33 is provided in the placement cavity 311. One end of the spring 33 is connected to the bottom of the placement cavity 311, and the other end of the spring 33 is connected to the telescopic rod 32. A support plate 34 is provided at the upper end of the telescopic rod 32. When the conveying assembly transports the packaging box to the lower mold 20, the packaging box is positioned above the support plate 34. The support plate 34 provides a supporting surface. When the pressing member 40 presses down on the middle of the packaging box, the middle of the packaging box fits against the supporting surface, preventing the packaging box from shaking and misaligning. As the pressing member 40 continues to press down, the telescopic rod 32 compresses the spring 33, and the telescopic rod 32 continues to move towards the bottom of the placement cavity 311, thereby effectively reducing the downward pressure of the pressing member 40. When the telescopic rod 32 moves to abut against the bottom of the placement cavity 311, the packaging box has been folded and formed. Then, the packaging box processing is completed by the nailing process. After the nailed packaging box is removed from the forming cavity 21, the pressing member 40 rises, the spring 33 returns to its original position, and the telescopic rod 32 drives the placement plate upward to process the next packaging box.

[0027] Preferred, such as Figure 4 As shown, the packaging box nailing machine also includes: a support frame 50, and a pressing component 40 including: a first driver 41 and a pressing block 42. The first driver 41 is mounted on the support frame 50. The support frame 50 ensures the correct installation of the first driver 41 and the stable operation of the pressing component 40 as a whole. The first driver 41 is a linear module, which drives the pressing block 42 to press down the packaging box. It should be noted that the first driver 41 can be a linear module, an electric push rod, or other types of drivers, as long as it can drive the pressing block 42 to perform lifting and lowering movements.

[0028] In this embodiment, as Figure 1 and Figure 2 As shown, the four sides of the lower mold 20 port are provided with forming surfaces 211 that slope inward from top to bottom. When the pressing member 40 presses down on the middle of the packaging box, the inclined forming surfaces 211 can evenly apply the pressure of the pressing member 40 to each fold of the packaging box, which can effectively make the packaging box shrink towards the bottom of the forming cavity 21 when folding, so as to help the packaging box fold and form better.

[0029] Preferred, such as Figure 1 and Figure 3As shown, the conveying mechanism 10 includes two clamping members 11 and two second drivers 13. The two clamping members 11 are spaced apart in the left-right direction. The packaging box is placed between the two clamping members 11. Each second driver 13 is drivenly connected to one clamping member 11. The second driver 13 is a pulley linear module, which drives the clamping members 11 to move in the feeding direction, thereby delivering the packaging box below the pressing member 40. It should be noted that the second driver 13 can be a pulley linear module, or a rotary motor or other type of driver, as long as it can drive the clamping members 11 to move in the feeding direction.

[0030] In this embodiment, the clamping member 11 is provided with limiting clamps 12. The packaging box is placed between the two limiting clamps 12, which can limit the position of the packaging box on the clamping member 11 and prevent the packaging box from being misaligned.

[0031] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this 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 describe all embodiments 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.
