Description

Technical Field

[0001] This application belongs to the field of packaging box processing technology, and in particular relates to an express delivery packaging box and its processing method. Background Technology

[0002] In the express delivery industry, express packaging boxes are frequently used to pack goods. Most existing packaging boxes are made of corrugated cardboard, which is a multi-layered adhesive. It consists of at least one layer of corrugated core paper and one layer of cardboard, and has high mechanical strength, which can withstand collisions and drops during handling. In the process of forming packaging boxes from corrugated cardboard, manufacturers usually punch and process the corresponding pre-formed cardboard for assembly, and then merchants automatically assemble and package the goods manually.

[0003] Patent CN113263772B discloses a cutting device for packaging box production and processing, including a base, an adsorption mechanism, and a negative pressure mechanism. A horizontal plate is fixedly connected to the upper end of the base via a bracket. The base is provided with an adsorption mechanism for adsorbing and fixing the packaging box. A negative pressure mechanism for generating negative pressure within the adsorption mechanism is fixedly connected to the horizontal plate. The adsorption mechanism includes a vertical rod, a flat plate, a strip cavity, an air suction hole, a rotary joint, an air outlet pipe, and an air suction pipe. A flat plate is rotatably connected to the upper end of the base via a vertical rod. A strip cavity is formed on the inner wall of the flat plate.

[0004] The aforementioned patent, when cutting packaging boxes, uses a first spring on a slide bar to increase the cutting effect of the cutter on the packaging box through the elasticity of the first spring. Although the cutting effect can be achieved, relying on the spring to increase the effect can easily lead to instability during the downward cutting, causing the cutter to wobble when moving up and down, ultimately resulting in errors in the cutting edge size, which needs to be improved. Summary of the Invention

[0005] The purpose of this application is to provide an express delivery packaging box and its processing method, which can solve the above-mentioned problems.

[0006] The purpose of this application is to provide an express packaging box, including a base plate, a first side plate and a second side plate located on both sides of the base plate, a top plate being disposed on the side of the first side plate away from the base plate, and a first end plate and a second end plate being disposed at both ends of the base plate. The first side plate, the second side plate, the first end plate and the second end plate of the base plate are connected by creases. The first side plate and the top plate are connected by creases.

[0007] The aforementioned express delivery packaging box, with its bottom plate, first side plate, second side plate, first end plate, second end plate, and top plate all connected by creases, allows the box to be easily folded into a flat shape when not in use. This significantly reduces storage and transportation space requirements, lowering logistics costs and improving warehouse storage efficiency. When needed, simply unfold and assemble the parts along the creases to quickly form a complete packaging box, simplifying the packaging process and improving work efficiency.

[0008] Furthermore, the present invention also provides a method for processing express packaging boxes, including the following steps:

[0009] S1. Material Selection: Select the cardboard material required for the express packaging box;

[0010] S2. Plate making and printing: Using letterpress, offset, gravure or flexographic printing technology, the designed patterns and text are printed onto the cardboard;

[0011] S3. Surface processing: The surface of the cardboard is coated to improve the wear resistance, water resistance, sun protection and other properties of the packaging box;

[0012] S4. Die-cutting: Use a die-cutting machine to die-cut the cardboard according to the designed pattern and size;

[0013] S5. Box making: After die cutting, the cardboard is folded into a box shape using a box making machine, and the edges are trimmed by an edge trimming machine. Finally, the box is fixed in shape by gluing, pressing and other operations.

[0014] Choosing the right cardboard material is fundamental to ensuring packaging box quality, directly impacting its durability and protective performance. The choice of printing technology and its quality directly affect the box's appearance; high-quality printing enhances brand image and increases consumer purchasing desire. Surface finishing improves the box's practicality and durability, maintaining its good appearance and performance in various environments. Die-cutting determines the box's shape and size; precise die-cutting ensures smooth assembly and an aesthetically pleasing appearance. The box-making process is the final step in transforming cardboard into a finished packaging box. Through gluing, pressing, and other operations, it ensures the various parts of the box are firmly connected, forming a stable structure. Edge trimming makes the edges smoother and more even, enhancing the overall aesthetics.

[0015] Furthermore: the edge trimming machine includes:

[0016] The base has a worktable and support frame on top;

[0017] The placement mechanism, set on the workbench, is used to place cardboard and can drive the cardboard to rotate;

[0018] The cutting mechanism, mounted on the support frame, is used to cut the edges of the cardboard;

[0019] The control device is connected to the placement mechanism and the cutting mechanism and is used to control the operation of both.

[0020] The control mechanism controls the operation of the placement mechanism and drives the cardboard to rotate, while the cutting mechanism cuts the edges of the cardboard after it rotates.

[0021] The base serves as the supporting foundation for the entire edge trimming machine, bearing all components such as the worktable, support frame, placement mechanism, and cutting mechanism. The worktable is positioned on top of the base, and the placement mechanism is mounted on the worktable to ensure accurate positioning of the cardboard before cutting. The support frame, located on the base, supports the cutting mechanism, enabling it to stably cut the cardboard and ensuring a smooth cutting process. The placement mechanism, located on the worktable, fixes and rotates the cardboard, ensuring smooth and continuous rotation during cutting to meet the needs of different shapes. The cutting mechanism, located on the support frame and above the worktable, trims the edges of the rotated cardboard. Under the command of the control device, the cutting mechanism starts when the cardboard rotates to the designated position, cutting the cardboard along a preset cutting path. In this application, through the coordinated work of all components, efficient and precise edge trimming of the cardboard is achieved.

[0022] Furthermore, the cutting mechanism includes:

[0023] Drive unit, top of support frame;

[0024] The cutting blade, located below the support frame, includes a rod and a blade section, with the rod connected to the output shaft of the driver;

[0025] Guide plates are installed at the bottom of the support frame and located on both sides of the rod.

[0026] A guide assembly is mounted on a guide plate and connected to the rod.

[0027] The rod section is equipped with a guide block that connects to the guide assembly.

[0028] The actuator, located at the top of the support frame, serves as the power source for the cutting blade, driving its vertical movement via linear motion. The actuator in this application is a cylinder. The cutting blade, located below the support frame, comprises a rod and a blade. The rod connects to the actuator, while the blade is used for cutting. Driven by the actuator, the cutting blade trims the cardboard edge by moving up and down. A guide plate is located at the bottom of the support frame, on both sides of the rod, providing stable guidance for the cutting blade and preventing it from shifting or wobbling during vertical movement. Simultaneously, a guide assembly is located on the guide plate and connected to a guide block on the rod. Through the connection between the guide block and the rod, the guide assembly precisely controls the cutting blade's trajectory. During cutting, the guide assembly ensures the cutting blade moves up and down along a preset path, thereby improving the accuracy and quality of the trimming. Throughout the cutting process, the guide assembly guides the cutting blade, making its vertical movement more stable, preventing deviation, and preventing wobbling during vertical movement, ultimately ensuring trimming accuracy, improving trimming quality, reducing rework rate, and increasing processing efficiency.

[0029] Furthermore, the guiding component includes:

[0030] The first guiding structure, disposed on the guide plate, includes a main guide groove, a linkage block disposed in the main guide groove and capable of sliding in the main guide groove, and a main damping component disposed on the guide plate and connected to the linkage block.

[0031] The second guide structure is disposed on the guide plate and spaced apart from the first guide structure, including a secondary guide groove, a mating block disposed in the secondary guide groove and capable of sliding in the secondary guide groove, and a secondary damping assembly disposed on the guide plate and connected to the mating block assembly.

[0032] The main guide groove and the auxiliary guide groove are arranged parallel to each other, with the starting point of the auxiliary guide groove being higher than the starting point of the main guide groove. The linkage block located in the main guide groove and the mating block located in the auxiliary guide groove cooperate with each other.

[0033] The first guiding structure, mounted on the guide plate, includes a main guide groove, a linkage block, and a main damping assembly. The main guide groove provides a sliding track for the linkage block, restricting its horizontal movement and ensuring it moves along a preset path during cutting. The linkage block is positioned within the main guide groove and can slide within it. It is connected to the cutting blade's rod via a guide block, transmitting the driver's power to the cutting blade. The main damping assembly, mounted on the guide plate and connected to the linkage block, increases the damping of the linkage block during sliding, reducing swaying due to inertia and improving cutting stability.

[0034] The second guiding structure is spaced apart from the first guiding structure on the guide plate. It includes a secondary guiding groove, a mating block, and a secondary damping assembly. The secondary guiding groove is parallel to the main guiding groove, but its starting point is higher than that of the main guiding groove. This allows it to provide different guiding and buffering forces to the cutting blade at different stages to adapt to different needs during the cutting process. The mating block is located within the secondary guiding groove and can slide freely within it. It cooperates with the linkage block and moves with the linkage block. The secondary damping assembly is located on the guide plate and connected to the mating block. Its function is similar to that of the main damping assembly; it increases damping during the sliding process, improving cutting stability.

[0035] Although the linkage block and the mating block are located in the main guide groove and the secondary guide groove respectively, they need to cooperate with each other during the cutting process to provide a double stabilizing and buffering effect for the cutting work. At the same time, the starting point of the secondary guide groove is higher than the starting point of the main guide groove, which can also provide an initial balance state for the cutting blade before the cutting begins, which helps to reduce shaking and impact during startup.

[0036] Furthermore, the linkage block assembly includes a contact slider connected to the guide block, a support plate disposed on one side of the contact slider, and a lever disposed on the support plate;

[0037] The mating block includes a sliding plate, a first sliding protrusion disposed on one side of the sliding plate and slidably mating with the secondary guide groove, a first protrusion and a second protrusion disposed on the other side of the sliding plate, and a toggle groove that mats with the toggle block is formed between the first protrusion and the second protrusion.

[0038] The auxiliary damping component and the mating block are hinged, and the pusher block contacts the pusher groove and can drive the mating block to move along the auxiliary guide groove.

[0039] The contact slider is directly connected to the guide block, thereby transmitting the driver's power to the cutting blade. A support plate is located on one side of the contact slider, providing a mounting base for the pusher block and connecting it to the contact slider. The pusher block, mounted on the support plate, engages with the pusher groove on the mating block and drives the mating block to slide along the secondary guide groove during movement. The sliding plate, as the main body of the mating block, has a first sliding protrusion on one side that engages with the secondary guide groove to ensure stable movement of the mating block within the groove. The other side has a first protrusion and a second protrusion, forming a pusher groove that engages with the pusher block. This pusher groove allows the pusher block to move the mating block, and the pusher block is positioned within the pusher groove at the start of cutting.

[0040] In this application, the secondary damping component and the mating block are hinged, allowing the mating block to have a certain degree of freedom to turn when pushed by the pusher block, in order to adapt to changes in the sliding direction. During the cutting process, the pusher block and the pusher groove are in close contact and interact with each other. When the driver drives the cutting blade to move up and down, the linkage block moves, and under the action of the pusher block, it drives the mating block to move together, causing it to slide along the secondary guide groove. This drives the main damping component and the secondary damping component to work together to buffer the movement of the cutting blade and achieve precise control of the cutting blade's movement, making its up and down movement more stable.

[0041] Furthermore, the second guiding structure also includes:

[0042] A limiting guide groove is set on the guide plate and communicates with the secondary guide groove, and the limiting guide groove is arc-shaped;

[0043] The second sliding protrusion is located on the side of the sliding plate away from the first sliding protrusion. The second sliding protrusion cooperates with the limiting guide groove and can slide from the secondary guide groove into the limiting guide groove.

[0044] The first sliding protrusion and the second sliding protrusion both have circular cross-sections, and when the second protrusion moves into the limiting guide groove, the first protrusion no longer contacts the toggle block.

[0045] A limiting guide groove is disposed on the guide plate and communicates with the secondary guide groove. Its shape is arc-shaped and can guide the movement of the sliding plate within a certain angle range. When the second sliding protrusion enters the limiting guide groove, it moves along the arc-shaped trajectory, causing one end of the mating block to move along the bending direction of the limiting guide groove. The second sliding protrusion and the first sliding protrusion are located on opposite sides of the sliding plate, jointly supporting and guiding the movement of the sliding plate. When the sliding plate moves to a certain position, the second sliding protrusion enters the limiting guide groove. During the cutting operation, i.e., the downward movement of the cutting blade, driven by the lever, the sliding plate moves the first and second sliding protrusions along the secondary guide groove. At this time, the lever is located in the actuation groove and is in contact with the first protrusion. When the second sliding protrusion enters the limiting guide groove, it changes the direction of movement of the sliding plate, causing it to move along the bending direction of the limiting guide groove, thus generating a turning motion. At this time, the lever is no longer in contact with the first protrusion, i.e., the mating block and the linkage block no longer cooperate, and the lever leaves the actuation groove. At the same time, the cutting operation continues, changing from the influence of double buffering to single buffering. This ensures the stability of the cutting blade's movement process and reduces the damping effect received during the final cutting, thereby avoiding deviation during the cutting process and ensuring the stability of the final cutting.

[0046] Furthermore, during the cutter's reset process—that is, its upward movement—as the shifting block moves upward, the shifting lever contacts the second protrusion, causing the second protrusion to move upward and the first protrusion to move from the limiting guide groove to the secondary guide groove. At this point, the shifting lever re-enters the shifting groove, meaning the mating block and the linkage block re-engage. Simultaneously, the reset process continues, transforming the single buffer into a double buffer, ensuring the stability of the cutter's movement and preparing for the next movement, preventing deviation in the next cutting process, and ensuring the stability of the final cut.

[0047] Furthermore, the main damping assembly includes a main damper and a first spring. The telescopic end of the main damper is connected to the linkage block, and the first spring is also connected to the linkage block. The other ends of the main damper and the first spring are mounted on a guide plate.

[0048] The secondary damping assembly includes a connecting plate, a secondary damper, and a second spring. One end of the connecting plate is connected to the secondary damper, and the other end is hinged to a mating block. One end of the second spring is connected to the mating block, and the other end of the second spring and the secondary damper are mounted on a guide plate.

[0049] The main damping assembly includes a main damper and a first spring. The telescopic end of the main damper is connected to the linkage block. When the cutting blade moves up and down, the main damper extends and retracts according to the movement of the linkage block, thereby providing damping force to slow down the movement speed of the linkage block and prevent excessive movement or vibration caused by inertia. The first spring is also connected to the linkage block, but its other end is mounted on the guide plate and provides elastic support, helping the linkage block maintain a stable posture during movement and also absorbing and mitigating the impact and vibration generated during cutting to a certain extent. The secondary damping assembly includes a connecting plate, a secondary damper, and a second spring. One end of the connecting plate is connected to the secondary damper, and the other end is hinged to the mating block, thus allowing for angle changes in the mating block. The secondary damper is connected to the connecting plate at one end and mounted on the guide plate at the other end. Its function is similar to that of the main damper, providing damping force to slow down the movement speed of the mating block and prevent vibration and swaying. One end of the second spring is connected to the mating block, and the other end is mounted on the guide plate, working in conjunction with the secondary damper to provide elastic support and mitigate impact.

[0050] During the cutting process, with the cooperation of the linkage block and the mating block, the main damping component and the secondary damping component work together on the cutting blade to provide the necessary damping force and elastic support, thereby reducing the vibration and shaking of the cutting blade during movement, improving the cutting accuracy and stability, and preventing deviations or deformations caused by uneven force.

[0051] The beneficial effects of this application are:

[0052] 1. During the cutting process, the guiding component ensures that the cutting blade moves up and down along a preset path, thereby improving the accuracy and quality of the cut edge. Throughout the cutting process, the guiding component guides the cutting blade, making its up-and-down movement more stable, preventing deviation, and preventing wobbling during movement. Ultimately, this ensures the accuracy of the cut edge, improves the quality of the cut edge, reduces rework rate, and increases processing efficiency.

[0053] 2. During the cutting operation, when the second sliding protrusion enters the limiting guide groove, it changes the movement direction of the sliding plate, causing it to move along the bending direction of the limiting guide groove, thus generating a turning motion. At this time, the push block is no longer in contact with the first protrusion, that is, the mating block and the linkage block no longer cooperate. The push block leaves the pushing groove, and the cutting operation continues. The effect of double buffering is changed to single buffering, which ensures the stability of the cutting blade movement process and reduces the damping effect received during the final cutting. Thus, it avoids the deviation during the cutting process and ensures the stability of the final cutting.

[0054] 3. The main damping assembly includes a main damper and a first spring. The telescopic end of the main damper is connected to the linkage block. When the cutting blade moves up and down, the main damper extends and retracts according to the movement of the linkage block, thereby providing damping force to slow down the movement speed of the linkage block and prevent excessive movement or vibration caused by inertia. The first spring is also connected to the linkage block, but its other end is mounted on the guide plate and provides elastic support, helping the linkage block maintain a stable posture during movement and also absorbing and mitigating the impact and vibration generated during the cutting process to a certain extent.

[0075] In this embodiment, selecting suitable cardboard material is fundamental to ensuring the quality of the packaging box, directly affecting its durability and protective performance. The choice of printing technology and the quality of printing directly impact the box's appearance; high-quality printing enhances brand image and increases consumer purchasing desire. Surface finishing enhances the practicality and durability of the packaging box, ensuring it maintains a good appearance and performance in various environments. Simultaneously, die-cutting determines the shape and size of the packaging box; precise die-cutting ensures smooth assembly and an aesthetically pleasing appearance. The box-making process is the final step in transforming cardboard into a finished packaging box.

Furthermore, edge trimming makes the edges of the packaging box smoother and more even, improving its overall aesthetics.

[0076] Example 3:

[0077] This application provides a processing method, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0078] like Figures 2 to 4 As shown, the edge trimming machine includes:

[0079] The base 200 has a worktable 210 and a support frame 220 on its top;

[0080] The placement mechanism 300 is set on the workbench 210 and is used to place cardboard and can drive the cardboard to rotate;

[0081] The cutting mechanism 400 is mounted on the support frame 220 and is used to cut the edges of the cardboard;

[0082] A control device, which is connected to the placement mechanism 300 and the cutting mechanism 400 and is used to control the operation of both.

[0083] The control mechanism controls the operation of the placement mechanism 300 and drives the cardboard to rotate, while the cutting mechanism 400 cuts the edge of the cardboard after it rotates.

[0084] In this embodiment, the base 200 serves as the supporting foundation for the entire edge trimming machine, supporting all components such as the worktable 210, support frame 220, placement mechanism 300, and cutting mechanism 400. The worktable 210 is positioned on top of the base 200, and the placement mechanism 300 is mounted on the worktable 210 to ensure accurate positioning of the cardboard before cutting. The support frame 220 is positioned on the base 200 to support the cutting mechanism 400, enabling it to stably cut the cardboard and ensuring a smooth cutting process. The placement mechanism 300 is positioned on the worktable 210 to fix and rotate the cardboard, ensuring smooth and continuous rotation during cutting to meet the cutting requirements of different shapes. The cutting mechanism 400 is positioned on the support frame 220 and above the worktable 210 to trim the rotated cardboard. Under the command of the control device, the cutting mechanism 400 starts when the cardboard rotates to the designated position and cuts the cardboard along the preset cutting path. In this application, through the coordinated work of various components, efficient and precise edge cutting of the cardboard is achieved.

[0085] Furthermore, the cutting mechanism 400 includes:

[0086] Drive 410, top of support bracket 220;

[0087] The cutting blade 420 is located below the support frame 220 and includes a rod 421 and a blade 422. The rod 421 is connected to the output shaft of the driver 410.

[0088] Guide plates 430 are disposed at the bottom of the support frame 220 and located on both sides of the rod 421;

[0089] A guide assembly is disposed on the guide plate 430 and connected to the rod portion 421;

[0090] The rod 421 is provided with a guide block 440 that is connected to the guide assembly.

[0091] The actuator 410 is located at the top of the support frame 220 and serves as the power source for the cutter 420. It drives the cutter 420 to move up and down via linear motion. The actuator 410 in this application is a cylinder. The cutter 420 is located below the support frame 220 and includes a rod 421 and a blade 422. The rod 421 is connected to the actuator 410, and the blade 422 is used for cutting. Driven by the actuator 410, the cutter 420 trims the cardboard edges by moving up and down. The guide plate 430 is located at the bottom of the support frame 220 and on both sides of the rod 421. It provides stable guidance for the cutter 420, preventing it from shifting or wobbling during its up and down movement. Meanwhile, a guiding component is mounted on the guide plate 430 and connected to the guide block 440 on the rod 421. Through the connection between the guide block 440 and the rod 421, the guiding component can precisely control the movement trajectory of the cutting blade 420. During the cutting process, the guiding component ensures that the cutting blade 420 moves up and down along a preset path, thereby improving the accuracy and quality of the cut edge. Throughout the cutting process, the guiding component guides the cutting blade 420, making its up and down movement more stable, preventing it from deviating, and preventing wobbling during up and down movement. Ultimately, this ensures the accuracy of the cut edge, improves the quality of the cut edge, reduces rework rate, and increases processing efficiency.

[0092] Example 4:

[0093] This application provides a processing method, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0094] like Figures 3 to 6 As shown, the bootloader components include:

[0095] The first guide structure 500 is disposed on the guide plate 430 and includes a main guide groove 510, a linkage block 520 disposed in the main guide groove 510 and capable of sliding in the main guide groove 510, and a main damping assembly 530 disposed on the guide plate 430 and connected to the linkage block 520.

[0096] The second guide structure 600 is disposed on the guide plate 430 and spaced apart from the first guide structure 500. It includes a secondary guide groove 610, a mating block 620 disposed in the secondary guide groove 610 and capable of sliding in the secondary guide groove 610, and a secondary damping assembly 630 disposed on the guide plate 430 and connected to the mating block 620.

[0097] The main guide groove 510 and the auxiliary guide groove 610 are arranged parallel to each other on the left and right sides. The starting point of the auxiliary guide groove 610 is higher than the starting point of the main guide groove 510. The linkage block 520 located in the main guide groove 510 and the mating block 620 located in the auxiliary guide groove 610 cooperate with each other.

[0098] In this embodiment, the first guide structure 500 is disposed on the guide plate 430 and includes a main guide groove 510, a linkage block 520, and a main damping assembly 530. The main guide groove 510 provides a sliding track for the linkage block 520, restricting its movement in the horizontal direction and ensuring that it can move along a preset path during the cutting process. The linkage block 520 is disposed within the main guide groove 510 and can slide therein. It is connected to the rod portion 421 of the cutting blade 420 through a guide block 440, transmitting the power of the driver 410 to the cutting blade 420. The main damping assembly 530 is disposed on the guide plate 430 and connected to the linkage block 520, used to increase the damping of the linkage block 520 during the sliding process, reduce the shaking caused by inertia, and improve the stability of the cutting.

[0099] The second guide structure 600 is spaced apart from the first guide structure 500 on the guide plate 430. It includes a secondary guide groove 610, a mating block 620, and a secondary damping assembly 630. The secondary guide groove 610 is arranged horizontally parallel to the main guide groove 510, but its starting point is higher than that of the main guide groove 510. This allows it to provide different guiding and buffering forces to the cutting blade 420 at different stages to adapt to different needs during the cutting process. The mating block 620 is disposed within the secondary guide groove 610 and can slide freely within it. It cooperates with the linkage block 520 and can move with the movement of the linkage block 520. The secondary damping assembly 630 is disposed on the guide plate 430 and connected to the mating block 620. Its function is similar to that of the main damping assembly 530, increasing damping during the sliding process and improving cutting stability.

[0100] Furthermore, although the linkage block 520 and the mating block 620 are located in the main guide groove 510 and the secondary guide groove 610 respectively, they need to cooperate with each other during the cutting process to provide a double stabilizing and buffering effect for the cutting work. At the same time, the starting point of the secondary guide groove 610 is higher than the starting point of the main guide groove 510, which can also provide an initial balance state for the cutting blade 420 before the cutting starts, which helps to reduce shaking and impact during startup.

[0101] Example 5:

[0102] This application provides a processing method, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0103] like Figures 3 to 6 As shown, the linkage block 520 group includes a contact slider 521 connected to the guide block 440, a support plate 522 disposed on one side of the contact slider 521, and a toggle block 523 disposed on the support plate 522.

[0104] The mating block 620 includes a sliding plate 621, a first sliding protrusion 622 disposed on one side of the sliding plate 621 and slidingly mating with the secondary guide groove 610, a first protrusion 623 and a second protrusion 624 disposed on the other side of the sliding plate 621, and a toggle groove 625 that mats with the toggle block 523 is formed between the first protrusion 623 and the second protrusion 624.

[0105] The auxiliary damping component 630 and the mating block 620 are hinged, and the toggle block 523 contacts the toggle groove 625 and can drive the mating block 620 to move along the auxiliary guide groove 610.

[0106] In this embodiment, the contact slider 521 is directly connected to the guide block 440, thereby transmitting the power of the driver 410 to the cutting blade 420. The support plate 522 is disposed on one side of the contact slider 521, providing a mounting base for the toggle block 523 and connecting the toggle block 523 and the contact slider 521. The toggle block 523 is disposed on the support plate 522 and can engage with the toggle groove 625 on the mating block 620, and during movement, it drives the mating block 620 to slide along the secondary guide groove 610. The sliding plate 621 serves as the main body of the mating block 620. One side of the sliding plate is provided with a first sliding protrusion 622 that slides in conjunction with the secondary guide groove 610 to ensure the stable movement of the mating block 620 within the secondary guide groove 610. The other side is provided with a first protrusion 623 and a second protrusion 624, which together form a shifting groove 625 that engages with the shifting block 523. The shifting groove 625 engages with the shifting block 523, enabling the shifting block 523 to drive the mating block 620 to move. At the start of cutting, the shifting block 523 is located within the shifting groove 625.

[0107] In this application, the secondary damping component 630 and the mating block 620 are hinged, allowing the mating block 620 to have a certain degree of freedom to turn when pushed by the pusher block 523, in order to adapt to changes in the sliding direction. During the cutting process, the pusher block 523 and the pusher groove 625 are in close contact and interact with each other. When the driver 410 drives the cutting blade 420 to move up and down, the linkage block 520 moves, and under the action of the pusher block 523, it drives the mating block 620 to move together, making it slide along the secondary guide groove 610. This causes the main damping component 530 and the secondary damping component 630 to work together to buffer the movement of the cutting blade 420 and achieve precise control of the movement of the cutting blade 420, making its up and down movement more stable.

[0108] Example 6:

[0109] This application provides a processing method, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0110] like Figures 3 to 6 As shown, the

[0111] The second guiding structure 600 also includes:

[0112] The limiting guide groove 640 is set on the guide plate 430 and communicates with the secondary guide groove 610, and the limiting guide groove 640 is arc-shaped;

[0113] The second sliding protrusion 650 is disposed on the side of the sliding plate 621 away from the first sliding protrusion 622. The second sliding protrusion 650 cooperates with the limiting guide groove 640 and can slide from the secondary guide groove 610 into the limiting guide groove 640.

[0114] The first sliding protrusion 622 and the second sliding protrusion 650 have circular cross sections, and when the second protrusion 624 moves into the limiting guide groove 640, the first protrusion 623 no longer contacts the toggle block 523.

[0115] In this embodiment, the limiting guide groove 640 is disposed on the guide plate 430 and communicates with the secondary guide groove 610. Its shape is arc-shaped and can guide the movement of the sliding plate 621 within a certain angle range. When the second sliding protrusion 650 enters the limiting guide groove 640, it moves along the arc-shaped trajectory, thereby causing one end of the mating block 620 to move along the bending direction of the limiting guide groove 640. The second sliding protrusion 650 and the first sliding protrusion 622 are located on opposite sides of the sliding plate 621, jointly supporting and guiding the movement of the sliding plate 621. When the sliding plate 621 moves to a certain position, the second sliding protrusion 650 enters the limiting guide groove 640. During the cutting operation of the cutting blade 420, i.e., its downward movement, driven by the lever 523, the sliding plate 621 drives the first sliding protrusion 622 and the second sliding protrusion 650 to move along the secondary guide groove 610. At this time, the lever 523 is located in the actuation groove 625 and is in contact with the first protrusion 623. When the second sliding protrusion 650 enters the limiting guide groove 640, it changes the direction of movement of the sliding plate 621, causing it to move along the bending direction of the limiting guide groove 640, thus generating a turning motion. At this time, the lever 523 is no longer in contact with the first protrusion 623, i.e., the mating block 620 and the linkage block 520 no longer cooperate, and the lever 523 leaves the actuation groove 625. At the same time, the cutting operation continues, changing from the influence of double buffering to single buffering, which ensures the stability of the cutting blade 420's movement process and reduces the damping effect received during the final cutting, thereby avoiding deviation during the cutting process and ensuring the stability of the final cutting.

[0116] Furthermore, during the reset process of the cutting blade 420, i.e., its upward movement, as the toggle block 523 moves upward, the toggle lever contacts the second protrusion 624, thereby causing the second protrusion 624 to move upward and the first protrusion 623 to move from the limiting guide groove 640 to the secondary guide groove 610. At this time, the toggle lever re-enters the actuating groove 625, meaning that the mating block 620 and the linkage block 520 re-engage. Simultaneously, the reset process continues, transforming the single buffer into a double buffer, ensuring the stability of the cutting blade 420's movement and preparing for the next movement, preventing deviation in the next cutting process, and ensuring the stability of the final cut.

[0117] Example 7:

[0118] This application provides a processing method, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0119] like Figures 3 to 6 As shown,

[0120] The main damping assembly 530 includes a main damper 531 and a first spring 532. The telescopic end of the main damper 531 is connected to the linkage block 520, and the first spring 532 is also connected to the linkage block 520. The other ends of the main damper 531 and the first spring 532 are mounted on the guide plate 430.

[0121] The secondary damping assembly 630 includes a connecting plate 631, a secondary damper 632, and a second spring 633. One end of the connecting plate 631 is connected to the secondary damper 632, and the other end is hinged to the mating block 620. One end of the second spring 633 is connected to the mating block 620, and the other ends of the second spring 633 and the secondary damper 632 are mounted on the guide plate 430.

[0122] In this embodiment, the main damping assembly 530 includes a main damper 531 and a first spring 532. The telescopic end of the main damper 531 is connected to the linkage block 520. When the cutting blade 420 moves up and down, the main damper 531 will extend and retract according to the movement of the linkage block 520, thereby providing damping force to slow down the movement speed of the linkage block 520 and prevent excessive movement or vibration caused by inertia. The first spring 532 is also connected to the linkage block 520, but its other end is mounted on the guide plate 430 and provides elastic support, helping the linkage block 520 maintain a stable posture during movement, and can also absorb and mitigate the impact and vibration generated during the cutting process to a certain extent. The secondary damping assembly 630 includes a connecting plate 631, a secondary damper 632, and a second spring 633. One end of the connecting plate 631 is connected to the secondary damper 632, and the other end is hinged to the mating block 620, thereby enabling the angle change of the mating block 620. The secondary damper 632 is connected to one end of the connecting plate 631 and the other end is mounted on the guide plate 430. Its function is similar to that of the primary damper 531, providing damping force to slow down the movement speed of the mating block 620 and prevent vibration and shaking. One end of the second spring 633 is connected to the mating block 620 and the other end is mounted on the guide plate 430. It works in conjunction with the secondary damper 632 to provide elastic support and mitigate impact.

[0123] During the cutting process, with the cooperation of the linkage block 520 and the mating block 620, the main damping component 530 and the secondary damping component 630 work together on the cutting blade 420 to provide the necessary damping force and elastic support, thereby reducing the vibration and shaking of the cutting blade 420 during movement, improving the cutting accuracy and stability, and preventing deviations or deformations caused by uneven force.
