Description

Technical Field

[0001] This application belongs to the technical field of cardboard box processing equipment, and in particular relates to a cutting mechanism for a cardboard box slotting machine. Background Technology

[0002] Cardboard box slotting machines are key pieces of equipment in the cardboard box production process, mainly used to cut slots in cardboard for easy folding. However, existing cardboard box slotting machines generally have a drawback: after completing the slotting process, the slotted edges still need to be treated by separate edge cutting and trimming equipment or manual operation, resulting in a cumbersome production process and low efficiency.

[0003] Traditional slotting machines are typically designed for a single slotting function, with their cutting blades primarily focused on cutting the groove opening, making it difficult to ensure the integrity of the slotted edges. For example, existing slotting machines often use single-layer blades that only operate on the center of the cardboard section to be slotted. This often results in burrs or residual waste at the edges after slotting. These issues not only affect the quality of the finished carton but also require additional resources for post-processing, increasing production costs. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this application is to provide a cutting mechanism for a carton slotting machine that can solve the above-mentioned problems.

[0005] The purpose of this application is to provide a cutting mechanism for a carton slotting machine, including a frame and further comprising:

[0006] The chassis is mounted on the frame and has a slotting mechanism inside. There is a processing space between the chassis and the frame for the cardboard to pass through.

[0007] The edge-cutting structure is mounted on the chassis and located within the processing space, and the edge-cutting structure can move within the processing space to perform edge-cutting on the cardboard;

[0008] A guide structure, located on one side of the frame, is used to transport and guide the cardboard after the edges have been cut.

[0009] The cut-edge structure is located between the chassis and the guide structure.

[0010] The above-mentioned edge-cutting mechanism of a carton slotting machine integrates the machine casing, edge-cutting structure, and guide structure into the frame, thereby achieving integrated processing of slotting and edge-cutting processes. After the slotting mechanism inside the machine casing completes the slotting of the cardboard, the edge-cutting structure can directly cut the edges of the cardboard within the processing space, eliminating the need to transfer the cardboard to separate equipment. This eliminates the additional processing steps after slotting in traditional production, effectively shortening the production process and improving overall processing efficiency. Simultaneously, the edge-cutting structure is located between the machine casing and the guide structure, allowing the cardboard to immediately enter the edge-cutting stage after slotting, and then be conveyed and exited by the guide structure, forming a continuous processing line. This also avoids transportation time and positioning deviations caused by process separation, reducing resource waste in production.

[0011] Furthermore, the cutting structure includes a guide rail mounted on the frame, a slider movably mounted on the guide rail, a driver for driving the slider to move, and a cutting assembly mounted on the bottom of the slider.

[0012] The guide rail and slider in the trimming structure provide a stable movement path for the trimming action. The movement of the slider on the guide rail can adjust the position of the cutting component to adapt to the trimming requirements of cardboard of different widths. This solves the problem of traditional slotting machines requiring manual blade replacement or blade head adjustment to fit different sized cartons, reducing operational complexity. The driver provides power for the slider movement, realizing automated adjustment of the trimming position, reducing manual intervention, avoiding positioning deviations caused by manual adjustment, and improving trimming accuracy. The cutting component is directly mounted on the bottom of the slider and moves synchronously with it, ensuring continuous and stable trimming during cardboard transport and avoiding discontinuous cutting caused by insufficient synchronization in trimming equipment.

[0013] Furthermore: the cutting assembly includes:

[0014] The mounting base has its top connected to the slider;

[0015] The cutting cylinder is installed at the bottom of the mounting base;

[0016] A pressurizing cylinder is installed at the bottom of the cutting cylinder;

[0017] The mounting bracket is set on the output shaft of the pressurizing cylinder, and a cutting blade is installed at the bottom of the mounting bracket.

[0018] Multiple cutting blades are installed.

[0019] The combination of a cutting cylinder and a pressurizing cylinder in the cutting assembly allows for adjustment of both cutting height and cutting pressure. Both cylinders are connected to an air source. The cutting cylinder lowers the pressurizing cylinder, accommodating cutting height requirements for cardboard of varying thicknesses without the need for manual blade or shim replacement. The pressurizing cylinder adjusts the pressure of the cutting blade on the cardboard by finely adjusting the extension and retraction of its output shaft. This allows for adjustment of cutting force based on the cardboard material, preventing damage from excessive pressure or burrs from insufficient pressure, thus improving cutting quality.

[0020] Meanwhile, by installing multiple cutting blades, the edges of the cardboard can be cut in multiple segments simultaneously, reducing the stress concentration of a single cut, lowering the risk of edge deformation, improving cutting efficiency, and adapting to the needs of mass production.

[0021] Furthermore, the mounting bracket includes:

[0022] The cutter head is U-shaped, and the cutting blade is installed inside the cutter head;

[0023] A guide rod is mounted on the cutter head, and a limit head is provided at the top of the guide rod;

[0024] The mounting plate is set on the output shaft of the pressurized cylinder, and its surface has multiple through holes for the guide rod to pass through;

[0025] A spring is fitted onto the guide rod and located between the top of the cutter head and the mounting plate;

[0026] The limiting head and the guide rod are connected by threads, and the limiting head presses the spring through the mounting plate.

[0027] The U-shaped cutter head provides a mounting base for the cutting blade, ensuring precise cutting direction. The combination of the guide rod and spring allows the cutter head to move elastically relative to the mounting plate. When there are slight undulations or uneven thickness on the cardboard surface, the spring force can push the cutting blade to always maintain close contact with the cardboard surface, achieving flexible cutting and avoiding the problems of missed cuts or rough edges caused by poor contact in traditional rigid cutting.

[0028] Meanwhile, in this application, the threaded connection between the limiting head and the guide rod facilitates the adjustment of the spring preload, allowing for flexible adjustment of the elastic pressure according to the cardboard hardness, adapting to the cutting needs of different cardboard materials, and also facilitating installation, disassembly, and maintenance.

[0029] Furthermore, the top of the cutting cylinder is provided with a mounting plate, which is mounted on the mounting base by screws.

[0030] The mounting plate on top of the cutting cylinder is connected to the mounting base with screws, making it easier to disassemble and replace the cutting cylinder and the components below. When the cutting blade wears out or a different type of blade needs to be replaced, the entire cutting assembly can be removed simply by loosening the screws, without disassembling other parts of the equipment, thus reducing blade change time.

[0031] Furthermore, the guiding structure includes:

[0032] A support guide is provided, one end of which is connected to the frame, and a groove is provided on its surface;

[0033] The first guide wheel is rotatably set in the groove and there are multiple of them;

[0034] The second guide wheel is mounted on the chassis and located in the machining space;

[0035] The support guide and the second guide wheel are each equipped with multiple sets.

[0036] The guiding structure, through the cooperation of the support guide and guide wheels, ensures stable transport of the cardboard after edge trimming. One end of the support guide connects to the frame, providing stable support for the cardboard and preventing positional shifts caused by its own weight during transport. Multiple first guide wheels within the grooves rotate to move the cardboard, reducing friction during transport, protecting the cardboard's appearance quality, and these first guide wheels rotate synchronously and are connected to a driver, such as a combination of belts and motors. Second guide wheels on the chassis can guide the cardboard out of the chassis and also press the cardboard firmly during cutting, improving trimming accuracy.

[0037] The beneficial effects of this application are:

[0038] 1. It can achieve integrated grooving and edge trimming, eliminating the separate edge trimming step after traditional grooving, forming a continuous processing production line, shortening the production process, and improving overall processing efficiency.

[0039] 2. It can adapt to different specifications of cardboard. The height and pressure can be adjusted by the cutting cylinder and the pressurizing cylinder. It is practical with the flexible structure of the mounting frame, which can effectively avoid cutting damage or burrs and improve the cutting quality.

[0040] 3. The cutting components can be quickly disassembled and assembled via the mounting plate, facilitating overall replacement or repair. Attached Figure Description

[0048] The cutting mechanism of the carton slotting machine provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0049] Example 1:

[0050] like Figures 1 to 4 As shown, this application embodiment provides a cutting mechanism for a carton slotting machine, including a frame 100, and further comprising:

[0051] The chassis 200 is mounted on the frame 100 and has a slotting mechanism inside. A processing space 210 for cardboard to pass through is provided between the chassis 200 and the frame 100.

[0052] The edge-cutting structure 300 is mounted on the chassis 200 and located within the processing space 210, and the edge-cutting structure 300 can move within the processing space 210 to perform edge-cutting on the cardboard.

[0053] The guide structure 500 is located on one side of the frame 100 and is used to transport and guide the cut cardboard.

[0054] The slit structure 300 is located between the chassis 200 and the guide structure 500.

[0055] In some embodiments of this application, such as Figure 1 As shown, the above-mentioned edge-cutting mechanism of a carton slotting machine integrates the machine housing 200, the edge-cutting structure 300, and the guide structure 500 into the frame 100, thereby achieving integrated processing of slotting and edge-cutting processes. After the slotting mechanism inside the machine housing 200 completes the slotting of the cardboard, the edge-cutting structure 300 can directly cut the edges of the cardboard within the processing space 210, without transferring the cardboard to a separate device. This eliminates the extra processing steps after slotting in traditional production, effectively shortening the production process and improving overall processing efficiency. Simultaneously, the edge-cutting structure 300 is located between the machine housing 200 and the guide structure 500, allowing the cardboard to immediately enter the edge-cutting stage after slotting, and then be conveyed and exported by the guide structure 500, forming a continuous processing line. This also avoids transportation time and positioning deviations caused by process separation, reducing resource waste in production.

[0056] Example 2:

[0057] This application provides a cutting mechanism for a carton slotting machine. In addition to the above-mentioned technical features, the cutting mechanism of the carton slotting machine in this application also includes the following technical features.

[0058] like Figure 2 As shown, the cutting structure 300 includes a guide rail 310 disposed on the frame 100, a slider 320 movably disposed on the guide rail 310, a driver 330 for driving the slider 320 to move, and a cutting assembly 400 mounted on the bottom of the slider 320.

[0059] In this embodiment, the cooperation between the guide rail 310 and the slider 320 in the edge-cutting structure 300 provides a stable movement path for the edge-cutting action. The movement of the slider 320 on the guide rail 310 can drive the cutting component 400 to adjust its position, adapting to the edge-cutting requirements of cardboard of different widths. This solves the problem of traditional slotting machines requiring manual tool replacement or adjustment of the cutter head 441 to adapt to different sized cartons, reducing operational complexity. The driver 330 provides power for the movement of the slider 320, realizing automated adjustment of the edge-cutting position, reducing manual intervention, avoiding positioning deviations caused by manual adjustment, and improving edge-cutting accuracy. The cutting component 400 is directly installed at the bottom of the slider 320 and moves synchronously with the slider 320, ensuring continuous and stable edge-cutting during cardboard transport, avoiding the problem of discontinuous cutting caused by insufficient synchronization of the edge-cutting equipment.

[0060] Example 3:

[0061] This application provides a cutting mechanism for a carton slotting machine. In addition to the above-mentioned technical features, the cutting mechanism of the carton slotting machine in this application also includes the following technical features.

[0062] like Figure 3 and Figure 4 As shown, the cutting assembly 400 includes:

[0063] Mounting base 410, the top of which is connected to slider 320;

[0064] Cutting cylinder 420 is installed at the bottom of mounting base 410;

[0065] The pressurizing cylinder 430 is installed at the bottom of the cutting cylinder 420;

[0066] Mounting bracket 440 is mounted on the output shaft of pressurizing cylinder 430, and cutting blade 450 is mounted on the bottom of mounting bracket 440;

[0067] Multiple cutting blades 450 are installed.

[0068] In this embodiment, the combination of the cutting cylinder 420 and the pressurizing cylinder 430 in the cutting assembly 400 enables adjustment of the cutting height and cutting pressure. Both the cutting cylinder 420 and the pressurizing cylinder 430 are connected to an air source. The cutting cylinder 420 drives the pressurizing cylinder 430 to move downwards, adapting to the cutting height requirements of cardboard of different thicknesses without the need for manual replacement of blades or shims. The pressurizing cylinder 430 adjusts the pressure of the cutting blade 450 on the cardboard by finely adjusting the extension and retraction of its output shaft, allowing for adjustment of the cutting force according to the cardboard material. This avoids damage to the cardboard due to excessive pressure or burrs due to insufficient pressure, thereby improving the cutting quality.

[0069] Meanwhile, by installing multiple cutting blades 450, the edges of the cardboard can be cut in multiple segments at the same time, reducing the stress concentration of a single cut, lowering the risk of edge deformation, improving cutting efficiency, and adapting to the needs of mass production.

[0070] Furthermore, the top of the cutting cylinder 420 is provided with a mounting plate 460, which is mounted on the mounting base 410 by screws.

[0071] The mounting plate 460 on top of the cutting cylinder 420 is connected to the mounting base 410 by screws, which makes it easier to disassemble and replace the cutting cylinder 420 and the components below it. When the cutting blade 450 is worn or needs to be replaced with a different type of blade, the entire cutting assembly 400 can be removed simply by loosening the screws, without disassembling other parts of the equipment, thus reducing blade replacement time.

[0072] Example 4:

[0073] This application provides a cutting mechanism for a carton slotting machine. In addition to the above-mentioned technical features, the cutting mechanism of the carton slotting machine in this application also includes the following technical features.

[0074] like Figure 4 As shown, the mounting bracket 440 includes:

[0075] The cutter head 441 is U-shaped, and the cutting blade 450 is installed inside the cutter head 441;

[0076] Guide rod 442 is mounted on cutter head 441, and limit head 443 is mounted on top of guide rod 442;

[0077] Mounting plate 444 is mounted on the output shaft of pressurizing cylinder 430, and its surface has multiple through holes for guide rod 442 to pass through;

[0078] Spring 445 is sleeved on guide rod 442 and located between top of cutter head 441 and mounting plate 444;

[0079] The limiting head 443 is connected to the guide rod 442 by a thread, and the limiting head 443 presses the spring 445 through the mounting plate 444.

[0080] In this embodiment, the U-shaped cutter head 441 provides a mounting base for the cutting blade 450, ensuring precise cutting direction. The cooperation between the guide rod 442 and the spring 445 allows the cutter head 441 to move elastically relative to the mounting plate 444. When there are slight undulations or uneven thickness on the cardboard surface, the elastic force of the spring 445 can push the cutting blade 450 to always maintain close contact with the cardboard surface, achieving flexible cutting and avoiding the problems of missed cuts or burrs caused by poor contact in traditional rigid cutting.

[0081] Meanwhile, in this application, the threaded connection between the limiting head 443 and the guide rod 442 facilitates the adjustment of the preload of the spring 445, and the elastic pressure can be flexibly adjusted according to the hardness of the cardboard to adapt to the cutting needs of different cardboard materials. It is also easy to install and disassemble, and easy to maintain.

[0082] Example 5:

[0083] This application provides a cutting mechanism for a carton slotting machine. In addition to the above-mentioned technical features, the cutting mechanism of the carton slotting machine in this application also includes the following technical features.

[0087] The second guide wheel 530 is mounted on the chassis 200 and located in the machining space 210;

[0088] Multiple sets of support guide 510 and second guide wheel 530 are provided.

[0089] In this embodiment, the guide structure 500, through the cooperation of the support guide 510 and the guide wheels, ensures stable transmission of the cardboard after edge trimming. One end of the support guide 510 is connected to the frame 100, providing stable support for the cardboard and preventing positional shift caused by the cardboard sagging under its own weight during transmission. Multiple first guide wheels 520 within the groove 511 rotate to move the cardboard, reducing friction during transmission and protecting the cardboard's appearance. These first guide wheels 520 rotate synchronously and are connected to a driver 330, such as a combination of a belt and a motor.
