[0002] In the modern packaging industry, the slitting and storage of cardboard boxes are key links to ensure the efficient operation of subsequent packaging production. With the booming development of e-commerce, logistics and other industries, the market demand for various types of packaging boxes continues to surge, which directly promotes the continuous expansion of the production scale of cardboard boxes. At the same time, it also puts forward higher requirements for the precision, efficiency and standardization of cardboard slitting and storage.

[0003] To address the aforementioned issues, existing patents offer solutions. However, current packaging cardboard slitting and storage devices typically lack an automatic clamping spacing adjustment structure and rely on manual adjustment. This makes it difficult to quickly adapt to cardboard of different widths, requiring frequent manual adjustments that are time-consuming and labor-intensive. Uneven clamping force can lead to easy damage to cardboard edges or displacement during slitting, affecting slitting accuracy and efficiency. Furthermore, the lack of a buffer storage structure makes it difficult to absorb impact during cardboard storage, resulting in cardboard bending and edge damage due to high-speed sliding or collisions, thus affecting the integrity of the cardboard.

[0004] To address this, a cardboard cutting and storage device for packaging boxes is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a packaging box cardboard cutting and storage device, which can solve the problems of existing packaging box cardboard cutting and storage devices that usually lack an automatic clamping spacing adjustment structure and rely on manual adjustment. This makes it inconvenient to quickly adapt to cardboard of different widths, thus requiring frequent manual adjustments, which is time-consuming and labor-intensive. The uneven clamping force leads to easy damage to the edges of the cardboard or displacement during cutting, affecting cutting accuracy and efficiency. Moreover, the lack of a buffer storage structure makes it difficult to absorb impact during cardboard storage, resulting in bending and edge damage to the cardboard due to high-speed sliding or collision, affecting the integrity of the cardboard.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a packaging box cardboard cutting and storage device, comprising a base, a cutting and clamping assembly disposed on the top of the base, and a buffer storage assembly disposed on the right side of the base. The cutting and clamping assembly includes a cutting frame fixedly connected to the top of the base, a drive motor fixedly connected to the bottom of the cutting frame, a bidirectional lead screw fixedly connected to the output end of the drive motor, connecting rods threaded to both sides of the bidirectional lead screw, a clamping frame fixedly connected to the bottom of the connecting rods, a pneumatic airbag disposed inside the clamping frame, a pressure sensing module embedded inside the clamping frame, and a silicone clamping pad adhered to the inner side of the pneumatic airbag.

[0007] Preferably, the buffered storage assembly includes an inclined guide plate fixedly connected to the right side of the base, a first buffer spring assembly fixedly connected to the left side of the inclined guide plate, and a buffer guide plate fixedly connected to the top of the first buffer spring.

[0008] Preferably, a storage frame is fixedly connected to the right side of the inclined guide plate, a second buffer spring assembly is fixedly connected to the bottom of the storage frame, and a buffer support plate is fixedly connected to the top of the second buffer spring assembly.

[0009] Preferably, a fixing bracket is fixedly connected to the outer side of the storage frame, and a baffle is engaged inside the fixing bracket.

[0010] Preferably, a lifting cylinder is fixedly connected to the top of the slitting frame, a top plate is fixedly connected to the output end of the lifting cylinder, an adjustment mechanism is fixedly connected to the bottom of the top plate, and a slitting blade is provided on the outside of the adjustment mechanism.

[0011] Preferably, a drive motor is fixedly connected to the outer side of the base, and a conveying roller assembly is fixedly connected to the output end of the drive motor.

[0012] Preferably, a waste collection rack is fixedly connected to the bottom of the base, and a waste collection box is slidably connected inside the waste collection rack.

[0013] Preferably, both sides of the top plate are fixedly connected to limit support rods, and the end of the limit support rod away from the top plate is slidably connected to the cutting frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This application achieves adaptive and stable clamping and precise cutting of cardboard of different thicknesses and materials through a slitting clamping component. The internal drive motor drives a bidirectional lead screw to automatically adjust the clamping distance. Combined with a pneumatic airbag and pressure sensor module, it forms dynamic clamping force control. Compared with traditional manual clamping devices, it can effectively avoid damage to the cardboard edge due to excessive clamping or slitting displacement due to excessive looseness. It improves the stability of the slitting process and the adaptability to various cardboard types, and solves the problems of time-consuming adjustment and low slitting accuracy caused by uncontrollable clamping force in traditional devices.

[0016] 2. This application uses a buffered storage component to achieve buffered transport and neat stacking of cut cardboard. The first buffer spring group and the buffer guide plate inside absorb the transport impact force, and the second buffer spring group and the buffer support plate work together to achieve stable support. Combined with the limiting effect of the baffle, compared with traditional storage devices without buffer or with messy stacking, it can effectively reduce bending and edge damage during cardboard transport, improve the neatness of storage and the integrity of cardboard, and solve the problems of cardboard being easily damaged and stacked crookedly during storage by traditional devices.

[0023] 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.

[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] A cardboard slitting and storage device for packaging boxes includes a base 1. A slitting and clamping assembly 4 is provided on the top of the base 1, and a buffer storage assembly 5 is provided on the right side of the base 1. The slitting and clamping assembly 4 includes a slitting frame 401 fixedly connected to the top of the base 1. A drive motor 402 is fixedly connected to the bottom of the slitting frame 401. A bidirectional lead screw 403 is fixedly connected to the output end of the drive motor 402. Connecting rods 404 are threaded to both sides of the bidirectional lead screw 403. A clamping frame 405 is fixedly connected to the bottom of the connecting rods 404. A pneumatic airbag 406 is provided inside the clamping frame 405. A pressure sensing module 407 is embedded inside the clamping frame 405. A silicone clamping pad 408 is adhered to the inner side of the pneumatic airbag 406.

[0026] In this embodiment: by starting the drive motor 402, its output end drives the bidirectional lead screw 403 to rotate. Since the threads on both sides of the bidirectional lead screw 403 are in opposite directions, the connecting rod 404 threaded onto the lead screw will move relatively closer along the axial direction, thereby driving the bottom clamping frame 405 to move closer to the two edges of the cardboard. When the silicone clamping pad 408 inside the clamping frame 405 is about to contact the cardboard, the pneumatic airbag 406 inside the clamping frame 405 begins to inflate, pushing the silicone clamping pad 408 to apply pressure to the surface of the cardboard. At this time, the pressure sensing module 407 embedded in the clamping frame 405 monitors the clamping force in real time. When the pressure reaches the preset value, the pressure sensing module 407 sends a signal, the pneumatic airbag 406 stops inflating, and the silicone clamping pad 408 stably clamps the cardboard, preventing the cardboard from shifting during slitting and avoiding damage to the cardboard due to excessive clamping. After slitting is completed, the pneumatic airbag 406 deflates and contracts, the drive motor 402 rotates in the opposite direction, and the bidirectional lead screw 403 drives the connecting rod 404 and the clamping frame 405 to move to both sides, releasing the cardboard and completing one clamping and slitting cycle.

[0027] Specifically, such as Figure 3 As shown, the buffer storage assembly 5 includes an inclined guide plate 501 fixedly connected to the right side of the base 1, a first buffer spring assembly 502 fixedly connected to the left side of the inclined guide plate 501, and a buffer guide plate 503 fixedly connected to the top of the first buffer spring.

[0028] Specifically, such as Figure 3 As shown, a storage frame 504 is fixedly connected to the right side of the inclined guide plate 501, a second buffer spring assembly 505 is fixedly connected to the bottom of the storage frame 504, and a buffer support plate 506 is fixedly connected to the top of the second buffer spring assembly 505.

[0029] Specifically, such as Figure 3 As shown, a fixing bracket 507 is fixedly connected to the outside of the storage frame 504, and a baffle 508 is snapped into the inside of the fixing bracket 507.

[0030] In this embodiment: when the slit cardboard enters the buffered storage assembly 5 under the push of the conveyor roller group 3, it slides downward along the inclined surface under its own gravity and thrust. The cardboard first contacts the buffer guide plate 503, and then the first buffer spring group 502 at the bottom of the buffer guide plate 503 is compressed and deformed by the impact force, absorbing part of the impact force and reducing the sliding speed of the cardboard. This prevents the cardboard from bending or being damaged at the edges due to excessive speed. After being buffered, the cardboard continues to slide along the inclined guide plate 501 to the storage frame 504 on the right. After entering the storage frame 504, it falls on the buffer support plate 506, thus buffering the cardboard. The second buffer spring assembly 505 at the bottom of the support plate 506 is compressed by gravity, further buffering the impact of falling and making the cardboard stable. The baffle 508 inside the fixing bracket 507 on the outside of the storage frame 504 limits the two sides of the cardboard to prevent it from shifting during stacking and ensures that the cardboard is stacked neatly along the same baseline. As the number of stacks increases, the buffer support plate 506 gradually moves down under the action of the second buffer spring assembly 505 to adapt to the height change. When the stack reaches the preset number or height, the baffle 508 can be removed from the fixing bracket 507, and the neatly stacked cardboard can be taken out from the storage frame 504.

[0031] Specifically, such as Figure 4 As shown, a lifting cylinder 6 is fixedly connected to the top of the slitting frame 401, a top plate 7 is fixedly connected to the output end of the lifting cylinder 6, an adjustment mechanism 8 is fixedly connected to the bottom of the top plate 7, and a slitting blade 9 is provided on the outside of the adjustment mechanism 8.

[0032] Specifically, such as Figure 5 As shown, a drive motor 2 is fixedly connected to the outer side of the base 1, and a conveyor roller group 3 is fixedly connected to the output end of the drive motor 2.

[0033] In this embodiment: by setting up a lifting cylinder 6, a top plate 7, an adjusting mechanism 8, and a slitting blade 9, after the cardboard is stably clamped by the slitting and clamping assembly 4, the lifting cylinder 6 is activated, and its output end pushes the top plate 7 downward, so that the top plate 7 moves down synchronously with the adjusting mechanism 8 and the slitting blade 9 at the bottom. The adjusting mechanism 8 at the bottom of the top plate 7 will adjust the lateral position and cutting angle of the slitting blade 9 according to the preset cutting size through the internal transmission structure, ensuring that the slitting blade 9 is accurately aligned with the part of the cardboard that needs to be cut. When the slitting blade 9 contacts the surface of the cardboard, the lifting cylinder 6 continuously applies pressure, and the slitting blade 9 completes the cutting operation of the cardboard under the pressure. By setting up a drive motor 2 and a conveying roller group 3, the drive motor 2 starts working after the device is started, and its output end directly drives the conveying roller group 3 to rotate. After the cardboard to be processed is placed on the conveying roller group 3, the cardboard is smoothly conveyed to the slitting and clamping assembly 4 by means of the friction between the surface of the conveying roller group 3 and the cardboard, so as to realize the automated transfer of the cardboard between each process, reduce manual intervention, and improve the overall processing efficiency.

[0034] Specifically, such as Figure 1 As shown, a waste collection rack 10 is fixedly connected to the bottom of the base 1, and a waste collection box 11 is slidably connected inside the waste collection rack 10.

[0035] Specifically, such as Figure 1 As shown, limit rods 12 are fixedly connected to both sides of the top plate 7, and the end of the limit rod 12 away from the top plate 7 is slidably connected to the cutting frame 401.

[0036] In this embodiment: by setting up a waste collection rack 10 and a waste collection box 11, when the slitting blade 9 cuts the cardboard, the generated paper scraps, offcuts and other waste will fall into the waste collection rack 10 at the bottom of the base 1 through the waste channel reserved on the base 1 under the action of gravity. The waste collection box 11 will receive the waste. When the waste accumulates to a certain amount, the waste collection box 11 can be directly pulled out from the waste collection rack 10 for unified cleaning. By setting up a limiting support rod 12, when the lifting cylinder 6 pushes the top plate 7 to move up and down, the limiting support rod 12 will slide synchronously along the slide groove of the slitting frame 401, providing precise guidance for the lifting of the top plate 7, avoiding the slitting size error caused by the offset of the top plate 7, thereby ensuring the stability and accuracy of cardboard slitting.

[0037] Working Principle: In the process of using this cardboard slitting and storage device, the cardboard to be processed is first placed stably on the conveyor roller group 3. Then, the drive motor 2 starts, and its output directly drives the conveyor roller group 3 to rotate. Using the friction between the surface of the conveyor roller group 3 and the cardboard, the cardboard is smoothly conveyed along the top of the base 1 towards the slitting and clamping assembly 4. When the front end of the cardboard moves to the preset slitting position below the slitting frame 401, the drive motor 2 stops working, and the conveyor roller group 3 stops rotating. At this time, the drive motor 402 at the bottom of the slitting frame 401 starts, and its output drives the bidirectional lead screw 403 to rotate. Since the threads on both sides of the bidirectional lead screw 403 are in opposite directions, the connecting rods threaded onto both sides of the lead screw... Under the rotation of the lead screw, rod 404 moves closer to the cardboard along the axial direction. The clamping frame 405, fixedly connected to the bottom of rod 404, also moves synchronously, gradually approaching the edges of the cardboard. When the silicone clamping pad 408 inside the clamping frame 405 is about to contact the edge of the cardboard, the pneumatic airbag 406 inside the clamping frame 405 begins to inflate. The airbag expands gradually with increasing pressure, pushing the silicone clamping pad 408 to apply pressure to the cardboard surface. Simultaneously, the pressure sensing module 407 embedded in the clamping frame 405 monitors the clamping force of the silicone clamping pad 408 on the cardboard in real time. When the pressure reaches a preset appropriate value, the pressure sensing module 407 feeds a signal back to the control system, and the pneumatic airbag 406 stops inflating. This ensures stable clamping of the cardboard to prevent displacement during slitting, while also preventing indentations or damage to the cardboard edges due to excessive clamping force. It achieves adaptive and stable clamping for cardboard of different thicknesses and materials. After the cardboard is securely clamped, the lifting cylinder 6 is activated, pushing the top plate 7 downwards. Its limiting support rod 12 slides along the inner side of the slitting frame 401, providing precise guidance for the lifting of the top plate 7 and preventing it from shifting or wobbling during movement. This ensures the verticality of the slitting blade 9. Next, the adjusting mechanism 8 begins operation, adjusting the lateral position and cutting angle of the slitting blade 9 according to the preset slitting size and shape through its internal transmission structure. This ensures that the slitting blade 9 accurately aligns with the position on the cardboard that needs to be cut. Then, the slitting blade 9 cuts the cardboard... During the cutting process, paper scraps, offcuts, and other waste materials generated fall through the waste trough on the base 1 under gravity into the waste collection rack 10 at the bottom, and finally into the waste collection box 11 that slides inside the waste collection rack 10, facilitating subsequent unified removal and cleaning, and maintaining a clean processing environment. After slitting, the lifting cylinder 6 drives the top plate 7 and the slitting blade 9 to return to their original positions, and the adjusting mechanism 8 also returns to its initial state. At the same time, the pneumatic airbag 406 deflates and contracts, the drive motor 402 rotates in the opposite direction, driving the bidirectional lead screw 403 to rotate in the opposite direction, and the connecting rod 404 and the clamping frame 405 move to both sides, releasing the clamp on the slitted cardboard. Then, the drive motor 2 starts again, and the conveyor roller group 3 continues to rotate, conveying the slitted cardboard forward.After being cut, the cardboard, under the combined action of its own weight and the thrust of the conveyor roller assembly 3, will come into contact with the buffer guide plate 503. The first buffer spring assembly 502 at the bottom of the buffer guide plate 503 will undergo compression deformation after being impacted, and absorb part of the impact force through the elasticity of the spring, reducing the sliding speed of the cardboard and preventing the cardboard from bending or being damaged at the edges due to violent collision with other parts due to excessive speed. After being buffered by the buffer guide plate 503, the cardboard continues to slide along the inclined guide plate 501 towards its storage frame 504. After entering the storage frame 504, the cardboard will fall on the buffer support plate 506, and then the second buffer spring assembly 505 at the bottom of the buffer support plate 506 will be subjected to the force of the cardboard's gravity. The compression further cushions the impact of the falling cardboard, allowing it to rest stably on the cushioning support plate 506. The outer baffle 508 of the storage frame 504 limits the sides of the falling cardboard, preventing it from shifting during stacking and ensuring each cardboard is neatly stacked along the same baseline. As the number of stacked cardboards increases, the cushioning support plate 506 gradually moves downwards under the elastic action of the second cushioning spring assembly 505 to adapt to changes in stacking height until the preset storage quantity or height is reached. Then, the baffle 508 is released from the fixing bracket 507, and the baffle 508 is removed. Finally, the stacked cardboard is removed from inside the storage frame 504.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
