[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] This application provides a packaging box die-cutting equipment, which solves the problem that in related technologies, packaging box die-cutting mechanisms usually require manual loading and unloading, which not only consumes a lot of time and manpower, but also has a relatively slow loading and unloading speed, affecting production efficiency.

[0021] Please refer to Figures 1-3. A packaging box die-cutting device includes: a worktable 1, on which a die-cutting mechanism 2 for die-cutting packaging boxes is provided, the die-cutting mechanism 2 including a lower template 26 disposed on the worktable 1; characterized in that conveyors 3 are provided at both ends of the worktable 1, the two conveyors 3 being used for feeding and unloading cardboard respectively, and a correction mechanism 4 is provided on one end of each conveyor 3 near the worktable 1, the correction mechanism 4 being used to guide the cardboard on the conveyor 3; a pushing mechanism 5 is provided between the two conveyors 3 and the top of the worktable 1, the pushing mechanism 5 being used to push the cardboard on one side of the conveyor 3 to the lower template 26, and to push the die-cut cardboard on the lower template 26 to the other side of the conveyor 3; the pushing mechanism 5 includes two housings 51 disposed opposite to each other, a pushing rod 52 slidably disposed between the two housings 51, a lifting unit 53 connected to the pushing rod 52, the lifting unit 53 being used to drive the pushing rod 52 to rise and fall, the housings 51 An internal drive unit 54 is provided, which is used to drive the lifting unit 53 to move along the length of the housing 51.

[0022] In the initial state, the lifting unit 53 is located at one end of the conveyor 3 used for feeding, and the push rod 52 is located above the conveyor 3.

[0023] The cardboard is placed on the conveyor 3 for feeding, and the conveyor 3 transports the cardboard toward the workbench 1. When the cardboard approaches the workbench 1, the correction mechanism 4 at the end of the conveyor 3 closest to the workbench 1 starts to work. The correction mechanism 4 guides and corrects the cardboard to ensure that the cardboard can be transported accurately along the predetermined path and to avoid the cardboard from deviating during the transport process.

[0024] Once the cardboard reaches the designated position, the pushing mechanism 5 starts to operate, and the lifting unit 53 drives the pushing rod 52 to descend, so that the bottom end of the pushing rod 52 is at the same height as the bottom end of the cardboard, so that the cardboard can be pushed smoothly.

[0025] Subsequently, the drive unit 54 is activated, causing the lifting unit 53 and the push rod 52 to move together. During the movement, the push rod 52 pushes the cardboard on the conveyor 3, thereby pushing the cardboard on the conveyor 3 onto the lower template 26 on the worktable 1.

[0026] After the cardboard is pushed onto the lower template 26, the die-cutting mechanism 2 starts working to perform die-cutting on the cardboard on the lower template 26, cutting the cardboard into the required packaging box shape.

[0027] After die-cutting is completed, the drive unit 54 is activated, driving the push rod 52 to push the die-cut cardboard on the lower template 26 onto the conveyor 3 on the other side. The unloading conveyor 3 is activated, transporting the die-cut cardboard to the next process or a designated position.

[0028] Subsequently, the lifting unit 53 drives the push rod 52 to rise and restore the original height, and the driving unit 54 drives the lifting unit 53 to return to the original position, and the above process is repeated again.

[0029] By using the die-cutting mechanism 2, conveyor 3, push rod 52, lifting unit 53 and drive unit 54 together, the automatic feeding, die-cutting and unloading process of cardboard is realized. It does not require frequent manual intervention, which greatly shortens the production cycle, improves production efficiency and can meet the needs of large-scale production.

[0030] The correction mechanism 4 guides and corrects the paperboard on the conveyor 3, ensuring that the paperboard can accurately reach the designated position on the lower template 26. This avoids die-cutting quality problems caused by paperboard position deviation and improves the die-cutting accuracy and product qualification rate.

[0031] As shown in Figures 1 and 3, specifically, the die-cutting mechanism 2 in this embodiment includes four columns 21 arranged in a rectangle on the worktable 1. A fixing plate 22 is directly mounted on the top of each of the four columns 21. A servo press 23 is mounted above the fixing plate 22. A lifting plate 24 is slidably arranged between the four columns 21. A die-cutting blade 25 is mounted below the lifting plate 24. The bottom end of the piston rod of the servo press 23 is connected to the lifting plate 24. The die-cutting blade 25 and the lower template 26 are arranged vertically opposite each other.

[0032] Before the equipment is started, the servo press 23 is in standby mode with its piston rod in the retracted position. At this time, the lifting plate 24 is in the higher position of the four columns 21, and the die-cutting knife 25 is fixed below the lifting plate 24, maintaining a sufficient safe distance from the lower template 26 on the worktable 1 so that the subsequent cardboard can be smoothly placed on the lower template 26.

[0033] The external pushing mechanism 5 accurately pushes the cardboard to be die-cut from the conveyor 3 onto the lower template 26 on the worktable 1. The control system sends a working command to the servo press 23. After receiving the command, the servo press 23 starts working. Its internal motor and other power devices drive the piston rod to extend downward. The downward movement of the piston rod directly drives the lifting plate 24 to slide down along the four columns 21. The columns 21 play a guiding role to ensure that the lifting plate 24 remains stable during the sliding process. During the downward movement of the lifting plate 24, the die-cutting blade 25 set below it moves downward together. As the die-cutting blade 25 continuously approaches the lower template 26, it eventually contacts the cardboard placed on the lower template 26. The servo press 23 continuously applies pressure, causing the die-cutting blade 25 to cut the cardboard. The die-cutting blade 25 cuts the cardboard according to the preset shape and size, cutting the cardboard into the required packaging box shape.

[0034] After die-cutting is completed, the control system sends another command to the servo press 23, causing its piston rod to retract upward. The upward movement of the piston rod drives the lifting plate 24 to slide upward along the four columns 21. After the lifting plate 24 and the die-cutting blade 25 return to their initial positions, the servo press 23 stops working and waits for the next die-cutting operation.

[0035] As shown in Figure 4, in one embodiment, the conveyor 3 includes a frame 31 with two side plates 32 arranged opposite each other on the frame 31. A transmission roller 33 is arranged between the two side plates 32, and a conveyor belt 37 is connected between the outer sides of the two transmission rollers 33. A drive motor 34 and a reducer 35 are arranged on one side plate 32. The output shaft of the drive motor 34 is connected to the input shaft of the reducer 35, and the output shaft of the reducer 35 is connected to one end of the transmission roller 33 on one side. Two receiving platforms 36 are arranged opposite each other between the two side plates 32, and the two receiving platforms 36 on the same side are located at both ends of the conveyor belt 37.

[0036] After the drive motor 34 starts, its output shaft begins to rotate and transmits power to the reducer 35. The reducer 35 reduces the input speed and increases the torque, and then outputs power from its output shaft to drive the transmission roller 33 to rotate. A conveyor belt 37 is connected between the outer sides of the two transmission rollers 33. Under the action of friction, the rotation of one transmission roller 33 will drive the conveyor belt 37 to move, which in turn drives the other transmission roller 33 to rotate, realizing the cyclic operation of the conveyor belt 37.

[0037] When the cardboard is placed on the conveyor belt 37, the movement of the conveyor belt 37 will drive the cardboard forward along the space between the side plates 32, completing the movement of the cardboard on the conveyor 3.

[0038] The receiving platform 36 is located at both ends of the conveyor belt 37, at the feeding end of the conveyor 3. When the external cardboard is placed on the conveyor 3, the receiving platform 36 can serve to receive and guide it, so that the cardboard can be placed stably on the conveyor belt 37, avoiding the cardboard from falling directly or being placed unstable.

[0039] At the unloading end of conveyor 3, when conveyor belt 37 transports the die-cut cardboard to the end, receiving platform 36 can receive the cardboard falling from conveyor belt 37, preventing the cardboard from falling directly to the ground or other unsuitable locations, and facilitating the subsequent collection and processing of the die-cut cardboard.

[0040] As shown in Figures 1 and 5, it should be noted that the workbench 1 is located between the side plates 32 on both sides, and the receiving platform 36 on the side closer to the workbench 1 is connected to the workbench 1; multiple guide rods 6 are arranged opposite each other on the workbench 1 on both sides of the lower template 26, and the upper surfaces of the guide rods 6, the lower template 26, and the conveyor belt 37 are all at the same horizontal height.

[0041] The workbench 1 is located between the two side plates 32, and the receiving platform 36 on the side closer to the workbench 1 is connected to the workbench 1, so that the conveyor 3 and the workbench 1 are closely connected to form a continuous production process.

[0042] Multiple guide rods 6 ensure the high consistency of the cardboard during conveying and die-cutting, avoiding problems such as cardboard jamming and tilting caused by height differences, and ensuring the smooth operation of the production process.

[0043] As shown in Figures 2 and 5, in this embodiment, the housing 51 is disposed between the two opposite side plates 32 and the top of the worktable 1, and the housing 51 is distributed along the length of the conveyor belt 37 and the worktable 1; an opening is provided on the opposite side of the two housings 51.

[0044] The housing is positioned above the side plate 31 and the worktable 1, which facilitates the drive unit 54 to drive the lifting unit 53 to move along one side conveyor 3 to the other side conveyor 3.

[0045] In one embodiment, the lifting unit 53 includes an electric push rod 531 disposed inside the housing 51, a fixed seat 532 connected to the piston rod of the electric push rod 531, the fixed seat 532 being L-shaped, and a push rod 52 disposed on the fixed seat 532, one end of the push rod 52 extending outward through the opening of the housing 51.

[0046] The electric push rod 531, which serves as the power source for the lifting unit 53, is located inside the housing 51. When the equipment control system issues a command, the electric push rod 531 starts to work, and its piston rod will extend and retract according to the command.

[0047] When cardboard needs to be pushed off worktable 1, the control system drives the piston rod of electric push rod 531 to extend. The fixed seat 532 is connected to the piston rod of electric push rod 531. When the piston rod extends or retracts, it transmits motion to the fixed seat 532, causing it to move along with the fixed seat 532. When the piston rod of electric push rod 531 extends, the fixed seat 532 drives the push rod 52 downwards. The extended portion of the push rod 52 applies force to the end of the cardboard on worktable 1, pushing the cardboard off worktable 1. When the piston rod of electric push rod 531 retracts, the push rod 52 rises back to its initial position, awaiting the next pushing task.

[0048] As shown in Figures 5 and 6, in one embodiment, the drive unit 54 includes a lead screw 541 rotatably disposed inside the housing 51. A mounting base 542 is threadedly connected to the outer side of the lead screw 541, and an electric push rod 531 is disposed on the mounting base 542. A second drive motor 543 and a second reducer 544 are disposed on the housing 51. The output shaft of the second drive motor 543 is connected to the input shaft of the second reducer 544, and the output shaft of the second reducer 544 is connected to the lead screw 541. The mounting base 542 has a threaded groove inside that matches the outer thread of the lead screw 541.

[0049] When drive motor 2 543 starts running, its output shaft transmits power to the input shaft of reducer 2 544. Reducer 2 544 reduces and increases the torque of the high-speed rotational power output by drive motor 2 543, and its output shaft drives lead screw 541 to rotate.

[0050] Because the mounting base 542 has a threaded groove inside that matches the outer thread of the lead screw 541, when the lead screw 541 rotates, due to the interaction of the threads, the mounting base 542 will move linearly along the axial direction of the lead screw 541. When the lead screw 541 rotates clockwise, the mounting base 542 will move along the lead screw 541 in one direction; when the lead screw 541 rotates counterclockwise, the mounting base 542 will move along the lead screw 541 in the opposite direction.

[0051] The electric push rod 531 is mounted on the mounting base 542. As the mounting base 542 moves linearly, the electric push rod 531 also moves accordingly, realizing the horizontal movement of the electric push rod 531 inside the housing 51, thereby driving the push rod 52 to perform pushing operations at different positions.

[0052] As shown in Figures 1 and 2, in one embodiment, the correction mechanism (4) includes a mounting bracket (41) disposed on the side plate (32), four mounting brackets (41) are arranged in pairs facing each other, an electric push rod 42 is disposed on the mounting bracket 41, and two insert rods 43 are inserted into the mounting bracket 41; the conveyor belt 37 is provided with two guide plates 44 facing each other, one end of the insert rod 43 is connected to the corresponding guide plate 44, and the piston rod of the electric push rod 42 is connected to the corresponding guide plate 44.

[0053] Guide plates 44 are positioned opposite each other on the conveyor belt 37, and insert rods 43 are inserted into the mounting bracket 41, providing support and guidance for the guide plates 44 to maintain a relatively stable position. The piston rod of the electric push rod 42 is also connected to the corresponding guide plate 44. At this time, the entire correction mechanism is in its initial set position, and a certain channel is formed between the guide plates 44 for the cardboard to be normally conveyed on the conveyor belt 37.

[0054] When the cardboard on the conveyor belt 37 enters the preset position, the electric push rod 42 is activated, and its piston rod extends, causing the guide plates 44 on both sides to move closer to each other, correcting the cardboard on the conveyor belt 37 and keeping the cardboard on the correct conveying path. At the same time, the insert rod 43 guides the guide plate 44 to facilitate the operation of the subsequent pushing mechanism 5.

[0055] Once the cardboard is guided back to the correct position, the control system will control the electric push rod 42 to return to its initial state, causing the guide plate 44 to return to its initial position and continue to provide a stable guide channel for the subsequent cardboard conveying.
