Therefore, there is an urgent need to develop an automatic box-opening device to replace manual opening, freeing up labor and improving work efficiency and safety. Utility Model Content

[0003] To solve the above problems, this utility model provides a packaging box opening machine.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A packaging box opening machine includes a bed installed in an explosion-proof operating room and a rotating clamping mechanism, a cutting mechanism, and a pressing mechanism installed on the bed. The rotating clamping mechanism is used to clamp and fix the packaging box and drive the packaging box to rotate. The cutting mechanism is installed on a worktable on one side of the packaging box and is used to circumferentially cut the box body. The pressing mechanism is installed above the packaging box and is used to abut against the top of the packaging box.

[0009] Furthermore, an intermediate plate is provided at the end of the piston rod of the lifting cylinder. The intermediate plate is connected to the supporting pressure plate through a connecting short pipe. The lower end of one guide rod is connected to the intermediate plate, and the lower end of the other guide rod passes through the intermediate plate and abuts against the supporting pressure plate.

[0010] Furthermore, the cutting mechanism includes a push cylinder, a hob holder, and a hob. The movable end of the push cylinder is connected to the hob holder, and the hob is mounted on a cutter holder at the end of the hob holder. The hob is capable of cutting the top edge of the packaging box. The push cylinder and the hob holder are mounted on a support base on the worktable.

Detailed Implementation

[0027] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0028] like Figure 1 , Figure 2As shown in the figure, a packaging box opening machine provided by this utility model includes a bed 1 installed in an explosion-proof operating room (not shown in the figure), and a rotating clamping mechanism, a cutting mechanism, and a pressing mechanism installed on the bed 1. The rotating clamping mechanism is used to clamp and fix the packaging box 00 and drive the packaging box 00 to rotate. The cutting mechanism is installed on a worktable 2 on one side of the packaging box 00 and is used to cut the box body of the packaging box 00 circumferentially. The pressing mechanism is installed above the packaging box 00 and is used to abut against the top of the packaging box 00. The rotating clamping mechanism, the cutting mechanism, and the pressing mechanism are all electrically connected to a controller (not shown in the figure). The controller can be placed inside the bed under the worktable. At the same time, a control panel connected to the controller can be installed on the side of the bed to facilitate the operator to input operating parameters. After the control panel controls the equipment through a PLC, it can automatically cut the packaging box. A rotating clamping mechanism is used to hold and fix the iron packaging box, and a pressing mechanism abuts against the top of the packaging box. After the personnel secure the packaging box, they exit the explosion-proof operating room and close the explosion-proof door. Then, as the packaging box rotates, the feeding mechanism automatically cuts the packaging box. After the cutting is completed, the controller controls the pressing mechanism and the rotating clamping mechanism to release the packaging box, and the personnel can then enter the explosion-proof operating room to manually remove the packaging box. The cutting process is completed in the explosion-proof operating room, which further improves the operational safety factor and ensures the personal safety of the personnel.

[0029] As a preferred structure, such as Figure 1 As shown, the workbench 2 is also equipped with a U-shaped protective cover 3, which is positioned opposite to the cutting mechanism on both sides of the packaging box 00. The protective cover prevents metal chips from flying during the cutting process, protecting other equipment in the explosion-proof operating room and reducing the workload of cleaning up debris on the floor.

[0030] In specific embodiments of this utility model, such as Figure 1 , 3 As shown in Figure 4, the top-pressing mechanism includes a lifting cylinder 4 and a supporting pressure plate 5. The supporting pressure plate 5 is connected to the movable end of the lifting cylinder 4. The lifting cylinder 4 is mounted on a support frame 6, which is connected to the worktable 2 at the top of the bed 1. The protective cover 3 is located on the side of the support frame 6. Guide rods 7 are symmetrically arranged on both sides of the lifting cylinder 4. The upper end of each guide rod 7 passes through a guide hole in the fixed plate and slides therewith. The lower end of each guide rod 7 is connected to the supporting pressure plate 5. The two guide rods 7 are symmetrically arranged on both sides of the supporting pressure plate 5. The supporting pressure plate has the same shape as the top surface of the packaging box, and the guide rods ensure that the supporting pressure plate is completely flush with the top surface of the packaging box.

[0031] To further optimize the above structure, an intermediate plate is installed at the end of the piston rod of the lifting cylinder. The intermediate plate is connected to the supporting pressure plate via a connecting short pipe. Simultaneously, the lower end of one guide rod is connected to the intermediate plate, and the lower end of another guide rod passes through the intermediate plate and abuts against the supporting pressure plate. In actual manufacturing, the size of the intermediate plate is smaller than the size of the supporting pressure plate. This structure facilitates processing and manufacturing; simply changing the lower supporting pressure plate allows for adaptation to packaging boxes of different sizes.

[0032] Alternatively, the bottom of the connecting short tube can be connected to the top surface of the supporting pressure plate 5 via a bearing. The connecting short tube is connected to the outer ring of the bearing, and the inner ring of the bearing abuts against the top surface of the supporting pressure plate 5. This structure enables the supporting pressure plate to both press against the packaging box and rotate with the packaging box.

[0033] In specific embodiments of this utility model, such as Figure 1 , 5 As shown, the cutting mechanism includes a push cylinder 8, a roller cutter holder 9, and a roller cutter 10. The movable end of the push cylinder 8 is connected to the roller cutter holder 9. The roller cutter 10 is mounted on a cutter holder 11 at the end of the roller cutter holder 9. The roller cutter 10 can cut the top edge of the packaging box 00. The push cylinder 8 and the roller cutter holder 9 are mounted on a support base 12 on the worktable 2. The bottom sides of the support base 12 can slide and engage with the rails 13 on the worktable 2. The push cylinder 8 and the roller cutter 10 are positioned opposite each other at the front and rear ends of the support base 12. By pushing the roller cutter with the push cylinder, and maintaining air supply, the roller cutter can be moved along with the rotating pallet. The roller cutter rolls and cuts the iron packaging box according to the shape of the pallet and the packaging box. After the roller cutter reaches its position, it rotates 2-5 times and then the pallet rotates in the reverse direction 2-5 times to ensure that the packaging box is cut open. The roller cutter then retracts, and the packaging box and the pallet stop rotating.

[0034] Further optimize the above solution, such as Figure 5 As shown, the worktable 2 is equipped with a positioning block 14, and the bottom of the hob cutter holder 9 is equipped with a limiting block 20 for limiting the position of the hob cutter holder 9. The cutter holder 11 is connected to the end of the hob cutter holder 9 by a height adjusting bolt 15, and the side of the cutter holder 11 is provided with an elongated hole that mates with the height adjusting bolt 15. In actual manufacturing, the positioning block can be installed on the support with a positioning bolt, and the position of the positioning block can be finely adjusted by the positioning bolt. The cooperation between the positioning block and the limiting block can limit the stroke of the hob cutter holder, ensuring that the hob cutter moves along the designed trajectory.

[0035] In specific embodiments of this utility model, such as Figure 3 , 4As shown, the packaging box 00 is placed on a tray 16 with a similar shape to the packaging box. The rotating clamping mechanism includes a clamping component 17 and a rotating component. The clamping component 17 is located on the top surface of the tray 16 and is used to clamp the lower edge of the packaging box 00 on the tray 16. The edge of the tray 16 extends to the outside of the clamping component 17. The rotating shaft 18 of the rotating component passes through the worktable 2 and is connected to the tray 16. This structure allows the rotating shaft to drive the tray and the packaging box on it to rotate. During the rotation, the packaging box contacts the cutting roller to complete the cutting.

[0036] In the specific design, the rotating component includes a rotating shaft 18 and a motor 19. The motor 19 drives the rotating shaft 18 to rotate through a transmission assembly. The motor 19 and the transmission assembly are located below the worktable 2. The transmission assembly can be a gear drive or a belt drive, which is existing technology and will not be described further.

[0037] Meanwhile, the clamping component 17 is a gripper cylinder, and the gripper cylinder's claws can clamp the four corners of the packaging box 00. In specific manufacturing, multiple claws can be designed so that they can clamp the four bottom edges and four corners of the packaging box, ensuring that the packaging box is firmly clamped.

[0038] like Figure 6 As shown, the specific application process of this utility model is as follows:

[0039] a. Personnel enter the explosion-proof operating room, place the packaging box on a tray, remove their hands, and press the start button on the control panel to start the operation;

[0040] b. When personnel leave the explosion-proof operating room, the explosion-proof door closes automatically, and the lifting cylinder drives the support plate to descend into place, pressing against the top of the packaging box;

[0041] c. The motor starts, the tray begins to rotate, the cylinder pushes the roller cutter to advance, the cylinder maintains air supply, the roller cutter rotates with the tray, the roller cutter rolls and cuts the iron packaging box according to the shape of the tray. After the roller cutter reaches the end, the tray is kept rotating for 2-5 revolutions, then the tray is reversed for 2-5 revolutions to cut the packaging box, the roller cutter retracts, and the tray stops rotating.

[0042] d. The lifting cylinder reverses its movement, causing the support plate to rise to its position, opening the explosion-proof door and allowing personnel to enter the explosion-proof operating room.

[0043] e. Manually remove the cut packaging tin box, being careful to avoid cutting your hands.

[0044] This completes one cycle of opening and closing the metal packaging box.

[0045] After finishing work, first press the "Stop" button on the control panel, then turn off the switch of the controller inside the workbench. Finally, turn off the AC power switch. Clean up the site, remove the ignition source, wipe the bed, apply oil to the rails, and cover with the dust cover.

[0046] In summary, the landmine cutting machine provided by this utility model adopts a vertical structure and can perform the task of opening various types of gun and ammunition packaging boxes and iron boxes. The equipment has a reasonable process layout, a high degree of automation, simple operation, good reliability and safety, high operating efficiency, significant economic benefits, small size and light weight, and is especially suitable for batch cutting of packaging boxes.

[0047] The machine works in conjunction with a pressing mechanism to secure the packaging box. After activating the rotating clamping mechanism, personnel exit the explosion-proof operating room. As the packaging box rotates, the cutting mechanism cuts the box. After cutting, the controller controls the pressing and rotating clamping mechanisms to release the packaging box, the cutting mechanism retracts, and personnel enter the explosion-proof operating room to manually remove the cut packaging box. This landmine cutting machine is suitable for cutting various types of iron-cased and plastic-cased landmines.

[0048] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
