Description

Technical Field

[0001] This application relates to the field of packaging material processing equipment technology, and in particular to an edge trimming device for gradient cushioned composite corrugated cardboard. Background Technology

[0002] With the rapid development of the packaging industry, gradient cushioning composite corrugated cardboard is increasingly widely used in high-end packaging fields such as electronic products and precision instruments due to its excellent cushioning performance and lightweight advantages. This type of cardboard achieves a gradient cushioning effect through a special structural design, which requires extremely high edge precision. Precise edge trimming is a key step in ensuring stable cushioning performance, aesthetic appearance, and suitability for packaging needs, and it also directly affects the overall quality and protective effect of the packaged product.

[0003] A search revealed Chinese Patent Publication No. CN222904196U, which discloses an edge trimming device for corrugated cardboard processing, relating to the field of corrugated cardboard processing technology. This invention includes a main body and a conveyor roller. A motor is mounted on the back of the main body, and a swing frame is connected to the motor's output end. A shearing blade is fixed at the bottom of the swing frame. A drive shaft is connected to the outer surface of the shearing blade, and a ratchet is connected inside the drive shaft via a torsion spring shaft. A bracket is fixed to one side of the outer surface of the main body, and a first pulley is connected inside the bracket. The inner ring of the first pulley has an inner ratchet groove. This invention, through the arrangement of the motor, swing frame, and shearing blade, allows the output end of the motor to drive the swing frame to swing up and down repeatedly after startup. This causes the shearing blade to work with the edge of the main body to form scissors, thereby cutting off the edges of the corrugated cardboard. Compared to rotary cutting, this method causes less damage to the waste edges of the corrugated cardboard, thus reducing dust generation and minimizing serious dust pollution. It facilitates edge trimming and is less prone to dust pollution.

[0004] The aforementioned patent specification mentions that "by setting up a motor, a swing frame, and a shearing blade, after the motor starts, the output end drives the swing frame to swing up and down repeatedly, so that the shearing blade cooperates with the edge of the main body of the device to form scissors, thereby cutting off the corners of the corrugated cardboard. Compared with rotary cutting, it causes less damage to the waste edges of the corrugated cardboard, so it is less likely to generate dust, and thus less likely to cause serious dust pollution; it is convenient for trimming and does not easily cause dust pollution." The above content can facilitate trimming and does not easily cause dust pollution. However, when facing the trimming needs of complex shapes, it is difficult to accurately control the movement trajectory of the blade, resulting in insufficient precision. Therefore, a gradient buffer composite corrugated cardboard edge trimming device is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this application is to provide an edge trimming device for gradient buffer composite corrugated cardboard, which aims to improve the problem of insufficient accuracy in some devices.

[0006] The edge trimming device for gradient buffer composite corrugated cardboard provided in this application adopts the following technical solution: An edge trimming device for gradient buffer composite corrugated cardboard includes a working plane, a working plate fixedly connected to the top of the working plane, multiple ventilation holes on the outside of the working plate, sliding brackets slidably connected to the inner sides of the top two side grooves of the working plane, a cutting mechanism disposed outside the sliding brackets, support bars slidably connected to the inner sides of the top two side grooves of the working plane, a fixing mechanism disposed outside the support bars, a conveying mechanism disposed outside the working plane, and a recycling mechanism disposed inside the working plane. The cutting mechanism includes a sliding housing, the inner side of which is slidably connected to the outside of the sliding brackets, a sliding wheel rotatably connected inside the sliding housing, a motor fixedly connected to the bottom of the sliding housing, a connecting frame fixedly connected to the bottom of the motor, and a transmission assembly fixedly connected to the outside of the connecting frame. The above technical solution involves placing gradient-buffered composite corrugated cardboard on the conveyor belt of the conveying mechanism. Motor 3 drives the pulley to rotate, causing the conveyor belt to transport the cardboard to the working plane. When the cardboard reaches the designated position, a photoelectric sensor triggers, and the driving component within the connecting plate of the fixing mechanism pushes the buffer pad down, fixing the cardboard to the working plane. Next, the control system, according to a preset path, drives the sliding housing of the cutting mechanism to move along the sliding grooves on both sides of the top of the working plane via sliding wheels on the sliding bracket. Simultaneously, Motor 1 drives the connecting frame and transmission components to move, and Motor 2 drives the rotating disk to rotate. Power is transmitted to the connecting column via the transmission rod, sliding plate, and slide rail, causing the cutting blade to rotate at high speed. During this process, the recycling mechanism is activated, and the fan inside the baffle generates negative pressure, sucking waste into the working plane. The cylinder pushes the push plate to send the waste to the cyclone separator for air-waste separation. This achieves full automation of the cardboard process from conveying, fixing, precise trimming to waste recycling, improving the overall product quality.

[0007] Preferably, the recycling mechanism includes a baffle, the outside of which is fixedly connected to the inside of the working plane, a second cylinder is fixedly connected to the outside of the baffle, a push plate is fixedly connected to the drive end of the second cylinder, multiple fans are arranged inside the baffle, and a cyclone separator is arranged outside the working plane. By adopting the above technical solution, the recycling mechanism starts operating synchronously. Multiple fans inside the baffle operate first, generating negative pressure suction to draw the waste generated by the cutting mechanism during cardboard trimming into the working plane through the ventilation holes of the working plate. As the waste accumulates, cylinder two starts, and its drive end pushes the push plate to further push the waste accumulated inside the working plane, allowing it to enter the cyclone separator outside the working plane through a specific channel. Inside the cyclone separator, the waste is efficiently separated from the air. Clean air is discharged outside the device, while the waste is collected centrally. This not only avoids the accumulation of waste inside the device affecting operation but also effectively prevents waste from flying and polluting the working environment. At the same time, it achieves directional collection of waste, facilitating subsequent centralized processing and ensuring that the entire trimming process is clean, efficient, and environmentally friendly, thus improving the practicality and automation level of the device.

[0008] Preferably, the outer side of the sliding wheel is slidably connected to the top of the sliding bracket, the bottom of the transmission assembly is fixedly connected to a connecting column, and the bottom of the connecting column is rotatably connected to a cutting blade; By adopting the above technical solution, the sliding wheel, through its sliding connection with the top of the sliding bracket, drives the sliding outer shell to move along the grooves on both sides of the top of the working plane, determining the trimming path. Simultaneously, the second motor in the transmission assembly starts, transmitting power to the connecting column via a rotating disk, transmission rod, and other components, driving the cutting blade to rotate at high speed. As the sliding outer shell moves, the connecting column fixed to the bottom of the transmission assembly drives the cutting blade to move synchronously. The high-speed rotating cutting blade precisely mills the edges of the cardboard. The cooperation between the sliding wheel and the sliding bracket ensures the stability and flexibility of the cutting mechanism's movement, effectively guaranteeing the flatness and smoothness of the edges of the gradient buffer composite corrugated cardboard, and improving the overall product quality.

[0009] Preferably, the transmission assembly includes a second motor, which is externally fixedly connected to the outside of the connecting frame, and a rotating disk is fixedly connected to the drive end of the second motor. By adopting the above technical solution, when the sliding shell moves the connecting frame to the trimming position, the second motor is powered on and started. The second motor is fixed outside the connecting frame, and its drive end drives the rotating disk to rotate at high speed. The rotating disk transmits power to the cutting blade through the subsequent transmission components, so that it begins to mill the edge of the cardboard. The combination design of the second motor and the rotating disk in the transmission components can output power stably and efficiently, providing a continuous and stable speed for the cutting blade, ensuring the flatness and smoothness of the edge of the gradient buffer composite corrugated cardboard, and improving the processing quality and production efficiency of the product.

[0010] Preferably, a transmission rod is rotatably connected to the outer protruding shaft of the rotating disk, and a sliding plate is rotatably connected to the other end of the transmission rod; By adopting the above technical solution, when the motor drives the rotating disk to start rotating, the external protruding shaft of the rotating disk drives the transmission rod to swing in a circular motion. The other end of the transmission rod is rotatably connected to the sliding plate. Under the drive of the transmission rod, the sliding plate slides back and forth in a straight line along the slide rail. By converting the circular motion of the rotating disk into the linear motion of the sliding plate, the power is transmitted to the connecting column in a stable and efficient manner, so that the cutting blade obtains continuous and stable rotational power, thereby improving the quality and efficiency of the trimming operation.

[0011] Preferably, a slide rail is slidably connected to the outside of the sliding plate, and the slide rail is fixedly connected to the outside of the connecting frame; By adopting the above technical solution, when the transmission rod swings under the drive of the rotating disk, the sliding plate, which is rotatably connected to the transmission rod, slides back and forth linearly along the direction of the slide rail under the constraint of the slide rail. The slide rail is fixedly connected to the outside of the connecting frame, providing a stable sliding track for the sliding plate. Through the sliding cooperation with the slide rail, the sliding plate effectively converts the swinging power of the transmission rod into linear motion power and transmits it to the connecting column, thereby driving the cutting blade to rotate stably, realizing precise milling of the cardboard edge and ensuring the trimming quality of the gradient buffer composite corrugated cardboard.

[0012] Preferably, the fixing mechanism includes a connecting plate, the outside of which is fixedly connected to the top of the support bar, and a cylinder is fixedly connected inside the connecting plate, with a buffer pad fixedly connected to the drive end of the cylinder. By adopting the above technical solution, the control system immediately issues a command to start the fixing mechanism. At this time, the cylinder in the connecting plate of the fixing mechanism starts to work. The driving end of the first cylinder pushes the buffer pad downward. Since the connecting plate is fixedly connected to the top of the support bar, it provides stable support for the entire fixing process. As the buffer pad moves downward, it fits tightly against the surface of the cardboard, and firmly presses the cardboard onto the working plane without damaging it. Through the coordinated operation of the connecting plate, the first cylinder and the buffer pad, the fixing mechanism achieves rapid and stable fixing of the cardboard, ensuring the processing quality of the gradient buffer composite corrugated cardboard.

[0013] Preferably, the conveying mechanism includes a supporting housing, the outside of which is fixedly connected to the outside of the working plane, a motor three is fixedly connected to the outside of the supporting housing, a pulley is fixedly connected to the drive end of the motor three, two pulleys are rotatably connected to the inside of the supporting housing, and a conveyor belt is coupled to the outside of the two supporting housings. By adopting the above technical solution, after the cardboard is placed on the conveyor belt, the conveying mechanism starts to work. The motor fixed outside the support shell starts, and its drive end drives the pulley to rotate. Since the two pulleys are rotatably connected inside the support shell, and the conveyor belt is coupled to the outside of the two support shells, the rotating pulleys can drive the conveyor belt to run smoothly and continuously transport the cardboard to the designated processing area on the working plane. The support shell provides stable support for the pulleys and the conveyor belt, ensuring that the conveying process is stable and reliable, laying the foundation for the efficient operation of the entire trimming process.

[0014] In summary, this application includes at least one of the following beneficial technical effects: 1. The entire unit moves via motor one, while motor two drives the transmission assembly. Through the linkage of the rotating disk and transmission rod components, power is efficiently transmitted to the cutting blade, achieving high-speed and stable milling. This significantly improves work efficiency compared to traditional trimming methods. At the same time, this modular transmission reduces maintenance difficulty, and the clear division of labor and close collaboration of each component can effectively reduce trimming errors, ensure the flatness and smoothness of the edges of the gradient buffer composite corrugated cardboard, and improve the overall quality of the product. 2. The negative pressure suction generated by the fan inside the baffle can quickly suck the waste generated during the trimming process into the working plane, preventing the waste from flying around and ensuring a clean working environment and the health of the operators. The push plate driven by the cylinder can push the waste out in a direction, preventing the waste from accumulating inside the device and affecting operation, ensuring a smooth recycling process. Combined with a cyclone separator, the waste is effectively separated from the air, which reduces air pollution, facilitates centralized collection and processing of waste, promotes resource recycling and reuse, reduces production costs, and improves the automation level and continuous working capacity of the device, achieving a highly efficient and environmentally friendly waste treatment effect.

Detailed Implementation

[0016] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail below.

[0017] Example: An edge trimming device for gradient buffer composite corrugated cardboard, as shown in the figure. Figures 1 to 3 The system includes a working plane 1, which provides an installation platform and stable working space for the entire system. A working plate 2 is fixedly connected to the top of the working plane 1. Ventilation holes on the outside of the working plate 2 cooperate with the recycling mechanism 8 to form a waste recycling channel. Multiple ventilation holes are provided on the outside of the working plate 2. Sliding brackets 4 are slidably connected to the inner side of the sliding grooves on both sides of the top of the working plane 1. The sliding brackets 4 provide a movable mounting carrier for the cutting mechanism 5. By sliding flexibly within the sliding grooves, the cutting mechanism 5 is driven to move along the working plane 1. The cutting mechanism 5 is set on the outside of the sliding brackets 4. The cutting mechanism 5 is responsible for precise edge trimming of the gradient buffer composite corrugated cardboard. Support bars 3 are slidably connected to the inside of the sliding grooves on both sides of the top of the working plane 1. The support bars 3 can be adjusted according to the cardboard size and trimming requirements. The position can be flexibly adjusted to provide a stable installation base for the fixing mechanism 6, ensuring that the fixing mechanism 6 can accurately fix the cardboard. The fixing mechanism 6 is set on the outside of the support bar 3. The fixing mechanism 6 is used to quickly and firmly clamp the cardboard after it is delivered to the position, effectively offsetting the effect of the cutting force on the cardboard during the trimming process and preventing the cardboard from shifting or shaking. The conveying mechanism 7 is set on the outside of the working plane 1. The conveying mechanism 7 is used to realize the automatic conveying function of the cardboard, which smoothly and quickly conveys the cardboard from the initial position to the designated processing area of ​​the working plane 1. The recycling mechanism 8 is set on the inside of the working plane 1. The recycling mechanism 8 is responsible for collecting and processing the waste generated during the trimming process, keeping the working environment clean, avoiding the accumulation of waste that affects the operation of the device, and facilitating the centralized recycling and processing of waste. The cutting mechanism 5 includes a sliding housing 51. The sliding housing 51 is slidably connected to the sliding bracket 4 through a sliding wheel 52, enabling it to move smoothly on the sliding bracket 4. The inside of the sliding housing 51 is slidably connected to the outside of the sliding bracket 4. The sliding wheel 52 is rotatably connected inside the sliding housing 51. The sliding wheel 52 contacts the top of the sliding bracket 4, and the rolling friction greatly reduces the resistance when the sliding housing 51 moves, making the cutting mechanism 5 move more smoothly and flexibly, and ensuring the accuracy of the trimming action. A motor 53 is fixedly connected to the bottom of the sliding housing 51. The motor 53 is used to provide power for the overall movement of the cutting mechanism 5. The drive connecting frame 54 and transmission assembly 55 move along the sliding bracket 4, enabling the cutting blade 57 to reach different cutting positions on the cardboard. The bottom of the motor 53 is fixedly connected to the connecting frame 54, which connects the motor 53 and the transmission assembly 55, transmitting power to the motor 53 and providing mounting positions for components such as the slide rail 554 in the transmission assembly 55, ensuring stable operation of the transmission assembly 55. The transmission assembly 55 is fixedly connected to the outside of the connecting frame 54, and the external sliding wheel 52 is slidably connected to the top of the sliding bracket 4. The transmission assembly 55... The power of motor 551 is converted and transmitted to drive the cutting blade 57 to rotate at high speed. It is the key transmission component for paperboard trimming. The bottom of the transmission component 55 is fixedly connected to the connecting column 56. The connecting column 56 transmits the power of the transmission component 55 to the cutting blade 57 and supports the cutting blade 57 to ensure its stability during high-speed rotation and cutting. The bottom of the connecting column 56 is rotatably connected to the cutting blade 57. The cutting blade 57 directly mills the edge of the paperboard through high-speed rotation. Its rotational accuracy and stability directly determine the trimming quality of the paperboard. The transmission assembly 55 includes a second motor 551, which provides rotational power to the entire transmission system and drives the rotating disk 552 to rotate. The second motor 551 is externally fixedly connected to the outside of the connecting frame 54. The driving end of the second motor 551 is fixedly connected to the rotating disk 552. The rotating disk 552 rotates at high speed under the drive of the second motor 551, and drives the transmission rod 553 to make circular oscillation through the external protruding shaft. One end of the transmission rod 553 is rotatably connected to the protruding shaft of the rotating disk 552, and the other end is rotatably connected to the sliding plate 555. The circular oscillation of the rotating disk 552 is converted into the linear motion of the sliding plate 555, and the rotational motion of the second motor 551 is converted into the oscillation motion of the transmission rod 553. The external protruding shaft of the rotating disk 552 is rotatably connected to the transmission rod 553, and the other end of the transmission rod 553 is rotatably connected to the sliding plate 555. The external sliding plate 555 is slidably connected to the slide rail 554, and the external sliding rail 554 is fixedly connected to the outside of the connecting frame 54. Specifically, the motor 72 of the conveying mechanism 7 drives the pulley 73 to rotate, which in turn drives the conveyor belt 74 to transport the gradient buffer composite corrugated cardboard to the designated position on the working plane 1. Then, the cylinder 62 of the fixing mechanism 6 pushes the buffer pad 63 down to firmly clamp the cardboard on the working plane 1, which is made of high-strength metal material and can withstand greater pressure and impact. Subsequently, the cutting mechanism 5 starts to operate. The motor 53 drives the sliding housing 51 and the transmission component 55 to move along the sliding bracket 4. At the same time, the motor 551 drives the rotating disk 552 to rotate. The power is transmitted to the cutting blade 57, which is made of high-hardness wear-resistant hard alloy, through the transmission rod 553 and the sliding plate 555, so that it rotates at high speed to mill the edge of the cardboard. The sliding bracket 4, support bar 3, connecting plate 61 and other components are made of lightweight high-strength aluminum alloy, while the sliding housing 51, connecting frame 54 and other key load-bearing components are made of alloy steel to enhance wear resistance. During the trimming process, the fan of the recycling mechanism 8 starts to generate negative pressure, which draws the waste into the working plane 1 through the vent holes of the working plate 2. Then, the cylinder 2 82 pushes the push plate 83 to send the waste to the cyclone separator 84 for air-dump separation. The baffle 81 and other components of the recycling mechanism 8 are made of corrosion-resistant plastic to prevent the waste from corroding. After trimming, the flexible rubber buffer pad 63 of the fixing mechanism 6 is released, and the conveyor belt 74 made of wear-resistant rubber and high-strength fiber composite material of the conveying mechanism 7 sends out the finished cardboard.

[0018] Reference Figure 1 , Figure 2 and Figure 4 The recycling mechanism 8 includes a baffle 81, which is fixed inside the working plane 1 to form a closed space and guide the flow direction of waste. The outside of the baffle 81 is fixedly connected to the inside of the working plane 1, and a cylinder 82 is fixedly connected to the outside of the baffle 81. The cylinder 82 pushes the push plate 83 to move through telescopic movement, pushing the waste accumulated inside the working plane 1 to the cyclone separator 84 to realize the directional collection and transportation of waste. The drive end of the cylinder 82 is fixedly connected to the push plate 83, which is used to physically push the waste under the drive of the cylinder 82 to ensure that the waste smoothly enters the cyclone separator 84 from inside the working plane 1 to complete the collection work. Multiple fans are installed inside the baffle 81, and the cyclone separator 84 is installed outside the working plane 1. The cyclone separator 84 efficiently separates the sucked waste and air, separates the waste from the airflow and collects it in a concentrated manner, and the purified air is discharged outside the device to realize the environmentally friendly treatment and recycling of waste. The fixing mechanism 6 includes a connecting plate 61, which is fixedly connected to the top of the support bar 3 to provide an installation platform for the cylinder 62 and the buffer pad 63. The external part of the connecting plate 61 is fixedly connected to the top of the support bar 3, and the internal part of the connecting plate 61 is fixedly connected to the cylinder 62. The cylinder 62 is used to push the buffer pad 63 up and down through telescopic movement, and realizes the clamping and releasing action of the cardboard according to the control system command. The driving end of the cylinder 62 is fixedly connected to the buffer pad 63, which is used to contact the surface of the cardboard and press the cardboard under the push of the cylinder 62. It is made of flexible material, which can firmly fix the cardboard. The conveying mechanism 7 includes a support housing 71, which is fixed to the outside of the working plane 1 to provide installation support and protection for components such as motor 72, pulley 73, and conveyor belt 74, and to protect the internal components from external interference. The outside of the support housing 71 is fixedly connected to the outside of the working plane 1. Motor 72 is fixedly connected to the outside of the support housing 71. Motor 72 is used to drive pulley 73 to rotate, providing power for the operation of conveyor belt 74. The drive end of motor 72 is fixedly connected to pulley 73. Two pulleys 73 are rotatably connected to the inside of the support housing 71. The outside of the two support housings 71 is coupled to the conveyor belt 74. The conveyor belt 74 carries and conveys cardboard. Driven by the two pulleys 73, the cardboard is smoothly and continuously conveyed from the initial position to the processing area of ​​the working plane 1. Specifically, the conveying mechanism 7 starts first, with its motor 72 driving the pulley 73 to rotate. The conveyor belt 74, made of wear-resistant rubber and high-strength fiber composite material, then rotates, smoothly conveying the cardboard to the working plane 1. Once the cardboard is in place, the metal cylinder 62 of the fixing mechanism 6 pushes the flexible rubber buffer pad 63 down, using the stable platform provided by the connecting plate 61 to firmly clamp the cardboard onto the working plane 1. Subsequently, the cutting mechanism 5 trims the edges of the cardboard. During this process, the recycling mechanism 8 operates synchronously. The fan inside the corrosion-resistant plastic baffle 81 generates negative pressure, drawing waste into the working plane 1 through the ventilation holes of the working plate 2. The high-strength metal cylinder 82 pushes the pusher plate 83, directionally conveying the waste to the metal alloy cyclone separator 84 for air-dump separation. After trimming, cylinder 62 retracts and releases buffer pad 63, and conveying mechanism 7 continues to operate. Its metal support shell 71 provides reliable protection and support for motor 72 and pulley 73, driving conveyor belt 74 to deliver the finished cardboard. Each mechanism, with its appropriate material characteristics, ensures stable and efficient operation of the device.

[0019] The implementation principle of this application embodiment is as follows: The gradient buffer composite corrugated cardboard is placed on the conveyor belt 74 of the conveying mechanism 7. The motor 72 drives the pulley 73 to rotate, which drives the conveyor belt 74 to run and smoothly transport the cardboard to the processing area of ​​the working plane 1. When the cardboard reaches the designated position in the processing area, the photoelectric sensor installed around the working plane 1 detects the cardboard and transmits the signal to the control system. After receiving the signal, the control system immediately issues an instruction to start the cylinder 62 in the connecting plate 61 to push the buffer pad 63 downward. The buffer pad 63 is in close contact with the surface of the cardboard without damaging the cardboard. The cardboard is firmly pressed onto the working surface 1 to ensure that the cardboard will not shift during the trimming process. The operator inputs the preset trimming path into the control system in advance. According to the path data, the sliding housing 51 of the cutting mechanism 5 slides on the sliding bracket 4 through the internal sliding wheel 52. Simultaneously, driven by the control system, the sliding mechanism moves along the slide grooves on both sides of the top of the working plane 1 according to the preset path. The motor 53 at the bottom of the sliding housing 51 drives the connecting frame 54 and the transmission assembly 55 to move. The rotating disk 552 is driven to rotate by the motor 551. The rotating disk 552 drives the sliding plate 555 to slide on the slide rail 554 through the transmission rod 553 on the protruding shaft, thereby transmitting power to the connecting column 56, causing the cutting blade 57 to rotate at high speed. As the cutting mechanism 5 moves, the high-speed rotating cutting blade 57 mills the edge of the cardboard, removing the excess part and achieving precise trimming. During the cardboard trimming process, multiple fans inside the baffle 81 are activated, generating negative pressure suction. Waste is sucked into the working plane 1 under negative pressure. The cylinder 82 pushes the push plate 83 to push the waste further out. At the same time, in the cyclone separator 84, the waste is separated from the air. The air is discharged outside the device, while the waste is collected in the separator for subsequent unified processing.

Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
