Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard box production technology, specifically a corrugated cardboard box rotary die-cutting production device. Background Technology

[0002] Corrugated cardboard boxes are made from corrugated cardboard through die-cutting, creasing, stapling, or gluing. Corrugated cardboard boxes are one of the most widely used packaging products, consistently ranking first in usage among all packaging materials. This includes calcium-plastic corrugated cardboard boxes. For over half a century, corrugated cardboard boxes have gradually replaced wooden crates and other transport packaging containers due to their superior performance and good processing properties, becoming the mainstay of transport packaging.

[0003] The patent application "CN220661836U" discloses a high-efficiency production device for rotary die-cutting of corrugated cardboard boxes, comprising an arc-shaped base plate, a rebound pad, a mounting groove, and a fixed shaft. The upper end of the arc-shaped base plate is equipped with a rebound pad, and several mounting grooves are provided at the upper end of the arc-shaped base plate. A fixed shaft is provided at the lower end of the arc-shaped base plate, and a cutting assembly is installed in the mounting groove. This invention, by providing a cutting assembly, facilitates stable installation and easy replacement of the blade. The blade, in conjunction with a first and second pressure plate, is clamped within the mounting base. A spring and a limiting shaft further assist in clamping and stabilizing the blade. This invention also features a movable door, allowing for manual pulling to open the second pressure plate on the other side, separating the limiting shaft from the through hole for easy removal of the blade. Simultaneously, the through groove saves on blade consumables and reduces costs.

[0004] However, the above-mentioned device still has the following problems during implementation:

[0005] In the process of corrugated cardboard box processing, a rotary die-cutting machine is used to die-cut the corrugated cardboard. During cutting, in order to facilitate transportation, multiple pieces of corrugated cardboard are stacked on the loading table to ensure that the processing is uninterrupted. However, the rotary die-cutting machine will vibrate during production, causing the corrugated cardboard on the loading table to tilt due to shaking, which will cause material blockage and thus affect production efficiency. Utility Model Content

[0006] The purpose of this invention is to provide a corrugated cardboard box rotary die-cutting production device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A rotary die-cutting production device for corrugated cardboard boxes includes a rotary die-cutting machine and a loading platform. The loading platform is fixedly installed on one side of the rotary die-cutting machine. Two limiting plates are provided on the top of the loading platform. A sliding mechanism is provided on the side of the two limiting plates that are close to each other, and a transmission frame is fixedly connected on the side of the two limiting plates that are far apart from each other. An adjustment mechanism is provided at the bottom of the loading platform.

[0009] The adjustment mechanism includes a drive rod disposed at the bottom of the loading platform. A first bevel gear is fixedly connected to one end of the drive rod. Second bevel gears are meshed with both sides of the first bevel gear. A threaded rod is fixedly connected to one end of the second bevel gear. A transmission rod is drivenly connected to the surface of the threaded rod. The top of the transmission rod is fixedly connected to the bottom of the transmission frame. A threaded hole is provided at one end of the transmission rod to cooperate with the threaded rod.

[0010] Preferably, the sliding mechanism includes two sliding grooves formed on one side of the limiting plate, the inner wall of the sliding groove is provided with a rotating groove, a rotating block is slidably connected inside the rotating groove, a rotating rod is fixedly connected to the bottom of the rotating block, the bottom of the rotating rod extends through the interior of the sliding groove and is fixedly connected with a sliding wheel.

[0011] Preferably, a first bearing is fitted onto the surface of the rotating rod, and the top of the sliding wheel is rotatably connected to the inner wall of the sliding groove through the first bearing.

[0012] Preferably, a protective ring is fixedly connected to the surface of the sliding wheel, and the protective ring is made of rubber.

[0013] Preferably, a guide rod is fixedly connected to one side of the transmission frame, and guide holes that cooperate with the guide rod are provided on both sides of the loading platform.

[0014] Preferably, the bottom of the loading platform is fixedly connected to a first support bracket and two second supports brackets. The inner wall of the first support bracket is connected to the surface of the drive rod via a second bearing, and the inner wall of the second support bracket is rotatably connected to the surface of the threaded rod via a third bearing.

[0015] Preferably, one end of the drive rod is fixedly connected to a screwing block, and the screwing block has symmetrical screwing grooves on its circumferential side.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model, by setting an adjustment mechanism, enables the corrugated cardboard to be stacked neatly on the loading platform. By rotating the twisting block, the drive rod and the first bevel gear are driven to rotate around the second bearing. The first bevel gear and the second bevel gear are in a meshing state, which drives the second bevel gear and the threaded rod to rotate around the third bearing. When the threaded rod rotates, its external thread will squeeze the internal thread of the threaded hole, causing the two drive rods to move towards each other. At the same time, it drives the drive frame and the limiting plate to move along the trajectory of the guide rod and the guide hole until the limiting plate is close to the corrugated cardboard, thereby preventing the corrugated cardboard from tilting due to shaking and causing material blockage.

[0018] 2. By setting a sliding mechanism, this utility model enables the sliding wheel to contact the surface of the corrugated cardboard when the limiting plate is close to the corrugated cardboard. When the corrugated cardboard is conveyed, the sliding wheel, rotating rod and rotating block will rotate around the first bearing. The rotation of the sliding wheel improves the conveying efficiency of the corrugated cardboard and avoids blockage due to friction. Attached Figure Description

[0025] 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.

[0026] Please see Figure 1 - Figure 5 This utility model provides a technical solution:

[0027] Example 1:

[0028] A corrugated cardboard box rotary die-cutting production device includes a rotary die-cutting machine 1 and a feeding platform 2. The feeding platform 2 is fixedly installed on one side of the rotary die-cutting machine 1. Two limiting plates 3 are provided on the top of the feeding platform 2. A sliding mechanism is provided on the side of the two limiting plates 3 that are close to each other, and a transmission frame 4 is fixedly connected on the side of the two limiting plates 3 that are far apart from each other. An adjustment mechanism is provided at the bottom of the feeding platform 2.

[0029] The adjustment mechanism includes a drive rod 5 located at the bottom of the loading platform 2. One end of the drive rod 5 is fixedly connected to a first bevel gear 6. Both sides of the first bevel gear 6 are meshed with second bevel gears 7. One end of the second bevel gear 7 is fixedly connected to a threaded rod 8. The surface of the threaded rod 8 is connected to a transmission rod 9. The top of the transmission rod 9 is fixedly connected to the bottom of the transmission frame 4. One end of the transmission rod 9 is provided with a threaded hole 10 that mates with the threaded rod 8.

[0030] In this embodiment, considering that the rotary die-cutting machine 1 will vibrate during the production process, causing the corrugated cardboard on the loading table 2 to tilt due to shaking, thus causing material blockage, an adjustment mechanism is set up so that after the corrugated cardboard is stacked on the loading table 2, the drive rod 5 and the first bevel gear 6 can be rotated around the second bearing 22 by rotating the twisting block 24. The first bevel gear 6 and the second bevel gear 7 are in a meshing state, so the second bevel gear 7 and the threaded rod 8 will be rotated around the third bearing 23. When the threaded rod 8 rotates, its external thread will squeeze the internal thread of the threaded hole 10, causing the two transmission rods 9 to move towards each other. At the same time, the transmission frame 4 and the limiting plate 3 will move along the trajectory of the guide rod 18 and the guide hole 19 until the limiting plate 3 is close to the corrugated cardboard, thereby avoiding the corrugated cardboard from tilting due to shaking and causing material blockage.

[0031] This solves the problem that the vibration generated during the production process of the rotary die-cutting machine 1 causes the corrugated cardboard on the loading table 2 to tilt due to shaking, thus causing material blockage.

[0032] A guide rod 18 is fixedly connected to one side of the transmission frame 4, and guide holes 19 that cooperate with the guide rod 18 are opened on both sides of the loading platform 2.

[0033] In this embodiment, by setting guide rod 18 and guide hole 19, when threaded rod 8 rotates to transmit power to transmission rod 9, the movement trajectory of transmission rod 9 and transmission frame 4 and other mechanisms can be restricted, so that they can only move along the trajectory of guide rod 18 and guide hole 19.

[0034] The bottom of the loading platform 2 is fixedly connected to a first support bracket 20 and two second supports brackets 21. The inner wall of the first support bracket 20 is connected to the surface of the drive rod 5 through a second bearing 22, and the inner wall of the second support bracket 21 is rotatably connected to the surface of the threaded rod 8 through a third bearing 23.

[0035] In this embodiment, by setting a first support bracket 20 and two second support brackets 21, the drive rod 5 and the threaded rod 8 can be supported, restricting the first bevel gear 6 and the second bevel gear 7 to only maintain a meshing state, while improving the smoothness of their rotation process.

[0036] One end of the drive rod 5 is fixedly connected to a screwing block 24, and screwing grooves 25 are symmetrically opened on the circumferential side of the screwing block 24.

[0037] In this embodiment, by setting the twisting block 24 and the twisting groove 25, a gripping point for rotating the first bevel gear 6 can be provided for the user, thereby facilitating the user to rotate the drive rod 5 and the first bevel gear 6.

[0038] Example 2:

[0039] Based on Embodiment 1, this embodiment uses an adjustment mechanism to control the limiting plate 3 to be close to the corrugated cardboard, thereby avoiding the situation where the corrugated cardboard tilts and causes material blockage. However, considering that direct hard contact between the corrugated cardboard and the limiting plate 3 will cause friction and affect the efficiency of normal conveying of the corrugated cardboard, the sliding mechanism in this application includes two sliding grooves 11 opened on one side of the limiting plate 3. The inner wall of the sliding groove 11 is provided with a rotating groove 12. A rotating block 13 is slidably connected inside the rotating groove 12. A rotating rod 14 is fixedly connected to the bottom of the rotating block 13. The bottom of the rotating rod 14 penetrates into the interior of the sliding groove 11 and is fixedly connected with a sliding wheel 15.

[0040] In this embodiment, considering that direct hard contact between the corrugated cardboard and the limiting plate 3 will cause friction and affect the efficiency of normal conveying of the corrugated cardboard, a sliding mechanism is set up so that when the limiting plate 3 is close to the corrugated cardboard, the sliding wheel 15 will contact the surface of the corrugated cardboard. When the corrugated cardboard is conveyed, the sliding wheel 15, the rotating rod 14 and the rotating block 13 will rotate around the first bearing 16. The rotation of the sliding wheel 15 improves the conveying efficiency of the corrugated cardboard and avoids blockage due to friction.

[0041] This solves the problem that friction would occur due to direct hard contact between the corrugated cardboard and the limiting plate 3, which would also affect the efficiency of normal corrugated cardboard conveying.

[0042] A first bearing 16 is fitted onto the surface of the rotating rod 14, and the top of the sliding wheel 15 is rotatably connected to the inner wall of the sliding groove 11 through the first bearing 16.

[0043] In this embodiment, by setting the first bearing 16, the rotating rod 14, the rotating block 13 and the sliding wheel 15 can be restricted to rotating only around the first bearing 16, while improving the smoothness of their rotation process.

[0044] A protective ring 17 is fixedly connected to the surface of the sliding wheel 15. The protective ring 17 is made of rubber.

[0045] In this embodiment, by setting a protective ring 17, wear on the surface of the corrugated cardboard can be avoided during the rotation of the sliding wheel 15, thus playing a protective role.

[0046] Working principle: After the user stacks the corrugated cardboard neatly on the loading table 2, he rotates the twisting block 24, which drives the drive rod 5 and the first bevel gear 6 to rotate around the second bearing 22. The first bevel gear 6 and the second bevel gear 7 are in a meshing state, which drives the second bevel gear 7 and the threaded rod 8 to rotate around the third bearing 23. When the threaded rod 8 rotates, its external thread will squeeze the internal thread of the threaded hole 10, causing the two transmission rods 9 to move towards each other. At the same time, it drives the transmission frame 4 and the limiting plate 3 to move along the trajectory of the guide rod 18 and the guide hole 19 until the limiting plate 3 is close to the corrugated cardboard, thereby preventing the corrugated cardboard from tilting due to shaking and causing material blockage.

[0047] When the limiting plate 3 is close to the corrugated cardboard, the sliding wheel 15 will contact the surface of the corrugated cardboard. When the corrugated cardboard is conveyed, the sliding wheel 15, the rotating rod 14 and the rotating block 13 will rotate around the first bearing 16. The rotation of the sliding wheel 15 will improve the conveying efficiency of the corrugated cardboard and avoid blockage due to friction.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
