Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper box processing technology, specifically to a high-speed die-cutting pressure adaptive adjustment structure for paper box products. Background Technology
[0002] High-speed die-cutting of paper boxes is an automated production process that utilizes advanced die-cutting equipment to complete die-cutting, creasing, and embossing of flat cardboard, corrugated cardboard, and other materials in a single pass through precise molds and powerful pressure within a very short production cycle, transforming them into foldable paper box blanks. The high-speed die-cutting pressure adaptive adjustment structure for paper boxes is an integrated mechatronics closed-loop control system that combines real-time sensing, intelligent decision-making, and precise execution. It is typically used in conjunction with a paper box die-cutting machine, and its core purpose is to automatically and continuously maintain the die-cutting pressure within the optimal range during high-speed die-cutting.
[0003] In the current use of paper box die-cutting equipment, the operator still needs to manually feed a single piece of cardboard onto the top of the workbench and cooperate with the downward movement of the die-cutting plate to carry out the die-cutting operation. This is not convenient enough, and the operator is too close to the dangerous working area, which poses a great safety risk and thus affects the production efficiency of paper box products. Utility Model Content
[0004] The purpose of this invention is to provide a high-speed die-cutting pressure adaptive adjustment structure for paper box products, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-speed die-cutting pressure adaptive adjustment structure for paper box products, comprising a die-cutting machine, an outer shell, and a control box. The outer shell is connected to both sides of the top of the die-cutting machine, and the control box is installed at the top of the outer shell. A telescopic cylinder is installed at the bottom center of the control box. A lower die-cutting plate is fixedly connected to the bottom output end of the telescopic cylinder, and a column is slidably connected inside the corner of the lower die-cutting plate. A buffer spring is sleeved in the middle of the outer wall of the column. A worktable is installed in the middle of the top of the die-cutting machine, and an optical sensing component is installed in the middle of the outer wall of the lower die-cutting plate.
[0006] A conveyor is connected to one side of the outer wall of the workbench, and limiters are fixedly connected to both sides of the bottom end of the conveyor. A base is slidably connected to the outer wall of the limiter, and the bottom end of the base is fixedly connected to the die-cutting machine. The limiter is inserted into the base for fixed connection and is used to install the conveyor.
[0007] A conveyor rod is installed above the conveyor table, and a roller is fixedly connected to the middle of the conveyor rod. The roller rotates to convey the cardboard box to the workbench to complete the automatic feeding.
[0008] By implementing automatic feeding, operators are no longer required to manually feed materials close to dangerous operating areas, thereby reducing safety risks and improving work efficiency.
[0009] Preferably, the bottom end of the column is fixedly connected to the top of the die-cutting machine, the top of the buffer spring is fixedly connected to the lower die-cutting plate, the bottom of the buffer spring is fixedly connected to the die-cutting machine, and the worktable is located below the lower die-cutting plate.
[0010] Preferably, the limiting member has an "L" shaped structure, and a base plate is connected to one side of the outer wall of the limiting member. The top of the base plate is fixedly connected to the bottom of the conveyor table. A threaded rod is threaded inside the base plate, and a threaded hole corresponding to the threaded rod is opened inside the base.
[0011] By rotating the threaded rod inside the base plate, the threaded rod is disengaged from the base, thus releasing the lock on the conveyor table. Subsequently, the conveyor table is moved to disengage the limiting component from the base, thereby completing the disassembly of the conveyor table.
[0012] Preferably, a servo motor is installed on one side of the bottom of the outer casing, and a rotating column is fixedly connected to the output end of the servo motor. The outer wall of the rotating column is provided with a sliding groove with an equal included angle, and a slider is connected inside the sliding groove.
[0013] The servo motor is started to drive the rotating column to rotate. The rotation of the rotating column will drive the fixed cylinder to rotate, and the rotation of the fixed cylinder will drive the conveyor rod to rotate. As the roller rotates, the cardboard on the top of the conveyor table is transported.
[0014] Preferably, a fixed cylinder is connected to one side of the outer wall of the slider, a return spring is fixedly connected to one side of the outer wall of the fixed cylinder, and a fixing member is fixedly connected to the other side of the outer wall of the fixed cylinder. The slider, the fixed cylinder and the fixing member form an integral structure.
[0015] The movement of the conveyor rod pushes the fixed cylinder, at which point the slider moves along the chute, guiding the fixed cylinder to move smoothly, and the movement of the fixed cylinder compresses the return spring.
[0016] Preferably, the side of the return spring away from the fixed cylinder is fixedly connected to the rotating column, and the rotating column, the fixed cylinder and the return spring form an elastic telescopic mechanism. A fixed cavity corresponding to the fixed component is opened inside one side of the conveying rod, and a limit cylinder is welded to the other side of the conveying rod.
[0017] The moving conveyor rod approaches the support column, causing the limiting cylinder to align with the support component. Then, the return spring resets, causing the fixing component to insert into the support component, thus completing the installation of the roller.
[0018] Preferably, a support member is rotatably connected inside the limiting cylinder, and the support member has a "T" shaped cross-section. A support column is fixedly connected to one side of the outer wall of the support member, and one side of the outer wall of the support column is fixedly connected to the outer shell, and the support columns are parallel to each other.
[0019] The limiting cylinder rotates around the support member as its axis, and then provides auxiliary support to the conveying rod through the support column, so that it drives the roller to rotate smoothly.
[0020] As can be seen from the above, the adaptive adjustment structure for high-speed die-cutting pressure of paper box products provided by this utility model has the following beneficial effects.
[0021] The cardboard on top of the conveyor is transported by the rotation of rollers, allowing it to enter the top of the workbench for die-cutting. This achieves automatic feeding, eliminating the need for manual intervention in high-risk areas and significantly reducing safety risks while improving work efficiency.
[0022] With simple push-in and pull-out actions, coupled with the automatic reset of the spring, the rollers can be replaced in minutes without the use of any special tools; and the conveyor table can be replaced in a short time, thereby reducing equipment downtime and improving overall operational efficiency.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0039] Please see Figures 1-14 This utility model provides a technical solution: a high-speed die-cutting pressure adaptive adjustment structure for paper box products, including a die-cutting machine 1, a housing 2, and a control box 3. The housing 2 is connected to both sides of the top of the die-cutting machine 1, and the control box 3 is installed on the top of the housing 2. A telescopic cylinder 4 is installed in the middle of the bottom of the control box 3. A lower die-cutting plate 5 is fixedly connected to the bottom output end of the telescopic cylinder 4. A column 6 is slidably connected to the inside of the corner of the lower die-cutting plate 5. A buffer spring 7 is sleeved in the middle of the outer wall of the column 6. A worktable 8 is installed in the middle of the top of the die-cutting machine 1. An optical sensing component 9 is installed in the middle of the outer wall of the lower die-cutting plate 5. The bottom of the column 6 is fixedly connected to the top of the die-cutting machine 1. The top of the buffer spring 7 is fixedly connected to the lower die-cutting plate 5, and the bottom is fixedly connected to the die-cutting machine 1. The worktable 8 is located below the lower die-cutting plate 5.
[0040] A conveyor table 10 is connected to one side of the outer wall of the workbench 8, and a limiting member 11 is fixedly connected to both sides of the bottom end of the conveyor table 10. A base 12 is slidably connected to the outer wall of the limiting member 11, and the bottom end of the base 12 is fixedly connected to the die-cutting machine 1. The limiting member 11 is inserted into the base 12 for fixed connection and is used to install the conveyor table 10. The limiting member 11 has an "L" shaped structure, and a base plate 13 is connected to one side of the outer wall of the limiting member 11. The top end of the base plate 13 is fixedly connected to the bottom of the conveyor table 10. A threaded rod 14 is threadedly connected inside the base plate 13, and a threaded hole corresponding to the threaded rod 14 is opened inside the base 12.
[0041] A conveyor rod 22 is installed above the conveyor table 10, and a roller 23 is fixedly connected to the middle of the conveyor rod 22. The roller 23 rotates to convey the paper box to the worktable 8 to complete the automatic feeding. A servo motor 15 is installed on one side of the bottom of the outer shell 2, and a rotating column 16 is fixedly connected to the output end of the servo motor 15. The outer wall of the rotating column 16 has a sliding groove 17 with an equal included angle, and a slider 18 is connected inside the sliding groove 17. A fixed cylinder 19 is connected to one side of the outer wall of the slider 18, and a return spring 20 is fixedly connected to one side of the outer wall of the fixed cylinder 19. A fixing part 21 is fixedly connected to the other side of the outer wall of the fixed cylinder 19. The slider 18, the fixed cylinder 19 and the... The fixing components 21 form an integral structure; the side of the return spring 20 away from the fixed cylinder 19 is fixedly connected to the rotating column 16, and the rotating column 16, the fixed cylinder 19 and the return spring 20 form an elastic telescopic mechanism. A fixing cavity corresponding to the fixing component 21 is opened inside one side of the conveying rod 22, and a limiting cylinder 24 is welded to the other side of the conveying rod 22; a support component 25 is rotatably connected inside the limiting cylinder 24, and the cross section of the support component 25 is a "T" shaped structure. A support column 26 is fixedly connected to one side of the outer wall of the support component 25, and one side of the outer wall of the support column 26 is fixedly connected to the outer shell 2, and the support columns 26 are parallel to each other.
[0042] In practice, the die-cutting machine 1 is placed in a designated location in the factory beforehand. The power is turned on, the control system performs a self-check, and after all moving parts return to their zero positions, a command is issued through the control box 3 on the top of the outer casing 2 to operate the telescopic cylinder 4 to drive the lower die-cutting plate 5 to move down along the column 6 until the lower die-cutting plate 5 compresses the buffer spring 7 and approaches the worktable 8. This allows the flat cardboard on the top of the worktable 8 to be die-cut by the lower die-cutting plate 5. The high-precision pressure sensor installed on the lower die-cutting plate 5, in conjunction with the optical sensing component 9, collects the pressure curve, peak pressure, and pressure distribution in real time at the moment of die-cutting and stamping, and then converts the pressure into a precise and quantifiable digital signal. Subsequently, the PLC receives the real-time pressure data from the sensor and compares it with the target value to calculate the error. The adjustment command calculated by the PLC is sent to the drive mechanism to fine-tune the overall height of the upper die frame. The slight change in the height of the upper die frame directly changes the die closing depth, thereby achieving precise control of the die-cutting pressure.
[0043] See Figure 7 , Figures 12-14 When the conveyor delivers the flat corrugated cardboard to the conveyor table 10, the servo motor 15 starts and drives the rotating column 16 and the fixed cylinder 19 connected to it to rotate synchronously. The fixed cylinder 19 drives its circumferential conveying rod 22 to rotate. At this time, the limiting cylinder 24 rotates under the constraint of the support member 25 and provides stable auxiliary support for the conveying rod 22 through the support column 26, ultimately ensuring that the roller 23 rotates smoothly. As the roller 23 rotates, it transports the cardboard on the top of the conveyor table 10, allowing the cardboard to enter the top of the worktable 8 for die-cutting.
[0044] Through the automatic feeding process formed by this transmission system, the cardboard is smoothly transported to the worktable 8 for die cutting. No manual intervention is required in high-risk areas throughout the process, which not only improves work efficiency but also significantly reduces safety risks. Furthermore, the feeding operation can be stopped when the roller 23 stops rotating.
[0045] See Figures 8-11 When roller 23 is damaged and needs to be replaced, first push the conveying rod 22 toward the rotating column 16. This operation will force the limiting cylinder 24 to disengage from the support 25 and push the fixing cylinder 19 to move together. The fixing cylinder 19 drives the slider 18 to slide along the slide groove 17, while compressing the return spring 20. Continue pushing until the conveying rod 22 is completely separated from the fixing member 21, and then the conveying rod 22 can be removed for maintenance of the roller 23 on its outer wall.
[0046] The entire process requires no special tools; the roller 23 can be replaced in minutes with simple push-in and pull-out actions, along with the automatic reset of the spring, thus shortening maintenance time and improving maintenance efficiency.
[0047] During installation, the conveyor rod 22 of the new roller 23 moves toward the support column 26, so that the limiting cylinder 24 and the support member 25 are accurately aligned. Then, it is released, and the compressed return spring 20 will automatically release its elasticity, pushing the fixing cylinder 19 to return to its original position, and finally allowing the fixing member 21 to be reinserted into the support member 25, completing the locking and installation.
[0048] See Figures 12-14 Rotate the threaded rod 14 inside the base plate 13 to disengage it from the base 12, thereby releasing the lock on the conveyor table 10. Then, move the conveyor table 10 so that the limiting member 11 at its bottom comes out of the base 12, thus completing the disassembly and facilitating replacement or maintenance.
[0049] During installation, align the limiting member 11 at the bottom of the conveyor table 10 and snap it into the base 12. Then, rotate the threaded rod 14 to screw it into the base 12 to complete the locking and installation, thereby reducing equipment downtime and improving overall operating efficiency.
[0050] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
