Description

Technical Field

[0001] This invention relates to the field of corrugated cardboard cutting technology, specifically to a corrugated cardboard processing and cutting device and method. Background Technology

[0002] Corrugated cardboard, also known as corrugated paperboard, consists of at least one layer of corrugated core paper and one layer of cardboard. Corrugated cardboard has good elasticity and extensibility, and can withstand collisions and drops during handling. It is mainly used to manufacture cartons, carton fillings, and other packaging materials for fragile goods. Before entering the production line for further processing, large-sized cardboard needs to be pre-cut according to the required dimensions to make it into individual carton boards.

[0003] For example, Chinese invention patent publication number CN 111232729 B discloses a corrugated cardboard edge collection device, including a base and a cutting blade. The base has a feeding channel, and a storage box for storing waste material is located below the base. An outlet connected to the storage box is opened on the base within the feeding channel. A pair of squeezing rollers for pulling the waste edges are rotatably installed in the storage box, with the rotation axis of the squeezing rollers perpendicular to the feeding direction of the feeding channel. The corrugated cardboard is conveyed along the feeding channel. When the corrugated cardboard passes under the cutting blade, the cutting blade rotates at high speed to cut the corrugated cardboard, guiding the waste edges through the outlet into the storage box. The squeezing rollers continuously pull the waste edges, causing the corrugated cardboard to enter the feeding channel. During the continuous cutting process, the waste edges are stored in the storage box, achieving centralized recycling of waste edges, facilitating subsequent processing, improving the production efficiency of corrugated cardboard, and ensuring the quality of the corrugated cardboard by preventing compression of the middle portion of the cardboard after cutting during the conveying process.

[0004] The aforementioned corrugated cardboard edge-cutting and collecting equipment can cut cardboard using a high-speed rotating cutting blade. However, it still has some shortcomings in use, such as poor cutting effect. Because the cutting blade has limited depth into the cardboard, it cannot cut through thicker cardboard, thus reducing the cutting effect. Therefore, a corrugated cardboard processing and cutting device and method are proposed to solve the above-mentioned technical problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a corrugated cardboard processing and cutting device and method, which has advantages such as good cutting effect and solves the problem that the cutting depth of the cutting blade is limited and cannot penetrate thicker cardboard.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a corrugated cardboard processing and cutting device, which includes a worktable with an opening on its top surface;

[0007] The workbench is provided with a horizontal cutting mechanism and a vertical cutting mechanism in sequence along the conveying direction, for cutting the cardboard horizontally and vertically.

[0008] The transverse cutting mechanism includes a cutting blade mounted on the worktable; its axis is perpendicular to the worktable in the vertical direction and is used to cut the middle layer of the corrugated cardboard in the transverse direction.

[0009] The vertical cutting mechanism includes at least one set of upper surface cutting components and lower surface cutting components; the upper surface cutting components and the lower surface cutting components are spaced apart along the transmission direction of the worktable; and both cutting components are vertically aligned with the openings on the worktable.

[0010] Both the upper surface cutting assembly and the lower surface cutting assembly include guide rollers and cutting rollers arranged vertically at intervals, with a transmission channel between them for the paperboard to pass through.

[0011] Furthermore, the guide roller is provided with a groove, and the cutting roller is equipped with a cutter, which is vertically aligned with the groove so that when the cutter rotates, it can be embedded in the groove to compress the corrugated cardboard in the transmission channel before vertical cutting.

[0012] Furthermore, the cutting roller and guide roller in the upper surface cutting assembly are respectively located above and below the transmission channel, while the cutting roller and guide roller in the lower surface cutting assembly are respectively located below and above the transmission channel.

[0013] Furthermore, the vertical height of the guide roller and the cutting roller is higher than the plane height of the worktable, so that the cardboard can be tilted after entering the conveying channel.

[0014] Furthermore, the transverse cutting mechanism includes a movable block disposed on the worktable and a first motor disposed on the movable block;

[0015] The cutting blade is mounted on the output shaft of the first motor, and a gap is left between it and the top of the worktable.

[0016] Furthermore, the moving block has an internal mounting opening for accommodating the cutting blade, and the first motor is used to drive the cutting blade to rotate.

[0017] Furthermore, a groove is provided on the outer side of the cutting roller along the x-axis, and a slider is provided in the groove. The slider is disposed on the inner peripheral wall of the cutter to limit the movement of the cutter, so that the cutting roller and the cutter rotate synchronously.

[0018] Furthermore, a positioning structure is provided on the slider to fix the position of the slider within the groove; and

[0019] The bottom end of the positioning rod is set as an arc surface, and the shape of the positioning groove is adapted to the arc surface on the positioning rod.

[0020] Furthermore, the workbench is equipped with a drive mechanism to support the vertical cutting mechanism;

[0021] The drive mechanism includes at least one set of cylinders symmetrically arranged on the worktable. The same mounting bracket is provided on the outer side of the output shaft of the two sets of cylinders. A set of two rotating rods are rotatably connected inside the mounting bracket and inside the worktable.

[0022] Based on this, a method of using a corrugated cardboard processing and cutting device, which utilizes the corrugated cardboard processing and cutting device described above, is characterized by comprising the following steps:

[0023] S1: Place the cardboard on the workbench and transport it along the x-axis.

[0024] S2: During the paperboard transport process, the paperboard first comes into contact with the transverse cutting mechanism, and under the action of the rotating cutting blade, the middle layer of the paperboard can be cut.

[0025] S3: After the middle layer of the cardboard is cut, the cardboard in the transmission will enter the vertical cutting mechanism, and the upper surface cutting component and the lower surface cutting component in the vertical cutting mechanism will cut the upper surface and the lower surface of the cardboard in sequence.

[0026] S4: Complete the cutting operation of the three structural layers of the corrugated cardboard.

[0027] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0028] 1. The corrugated cardboard processing and cutting device is equipped with a horizontal cutting mechanism and a vertical cutting mechanism. The horizontal cutting mechanism and the vertical cutting mechanism first cut the middle layer of the corrugated cardboard so that the corrugated cardboard can be cut through in subsequent cutting. After the middle layer of the corrugated cardboard is cut, the upper and lower layers of the corrugated cardboard are cut in turn to improve the cutting effect of the cardboard.

[0029] 2. This corrugated cardboard processing and cutting device, through the cooperation of a positioning rod and multiple positioning slots, enables the cutter to move on the cutting roller, so as to adjust the position of the cutter on the cutting roller and thus cut corrugated cardboard of different specifications.

[0030] 3. The corrugated cardboard processing and cutting device, under the action of the groove, allows the cutter to be embedded in the groove, and under the action of the groove, the cutter presses on the corrugated cardboard to improve the cutting effect of the cutter on the corrugated cardboard.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figure 1-7 The preferred embodiment of the present invention provides a corrugated cardboard processing and cutting device, which, based on the structural differences between corrugated cardboard and other cardboard, can cut the upper surface, lower surface and middle layer of the corrugated cardboard separately, thereby achieving a fast and efficient cutting operation of the corrugated cardboard.

[0042] It should be noted that, in existing technologies, corrugated cardboard generally consists of an upper layer, a lower layer, and an intermediate structural layer; such as Figure 8 As shown in the diagram, due to its three-layer structure, the traditional cutting device cannot achieve a good cutting effect on corrugated cardboard when cut by conventional cutting equipment.

[0043] Specifically, in a preferred embodiment of the present invention, the cutting device includes a worktable 1 with an opening on its top surface. A transverse cutting mechanism 5 and at least one vertical cutting mechanism 3 are sequentially arranged on the worktable 1 along its transmission direction. The transverse cutting mechanism 5 is used to cut the middle layer of the corrugated cardboard in the transverse direction. The vertical cutting mechanism 3 includes an upper surface cutting component and a lower surface cutting component, which are used to perform vertical cutting operations on the upper and lower surfaces of the cardboard, respectively. A driving mechanism 4 is provided on the worktable 1, which is connected to the vertical cutting mechanism 3 in a transmission manner, and is used to drive the vertical cutting mechanism 3 to move so as to vertically cut the cardboard.

[0044] In actual use, the operator first places the cardboard on the workbench 1. When the cardboard is transported along the z-axis on the workbench 1, it first passes through the transverse cutting mechanism 5, which can cut the middle layer of the corrugated cardboard. Then the cardboard enters the vertical cutting mechanism 3 and passes through the upper surface cutting component and the lower surface cutting component in sequence to cut the upper and lower surfaces of the cardboard. In this way, the three-layer structure of the corrugated cardboard is cut three times to achieve good cutting of the corrugated cardboard.

[0045] Furthermore, multiple sets of vertical cutting mechanisms 3 can be set up during the actual cutting process to improve the effect of vertical cutting of cardboard.

[0046] Please see Figure 2-3 In a preferred embodiment of the present invention, in order to adapt to corrugated cardboard of different widths and sizes and to allow the cutter 2 to change its cutting position, the cutter 2 is preferably slidably connected to the cutting roller 301.

[0047] Furthermore, to allow the cutter 2 to rotate together with the cutting roller 301, in a preferred embodiment of the present invention, the vertical cutting mechanism 3 further includes a groove 7 disposed along the x-axis on the outer side of the cutting roller 301. A slider 6 is disposed within the groove 7 and is disposed on the inner circumferential wall of the cutter 2 to limit the movement of the cutter 2, thereby ensuring that the cutting roller 301 and the cutter 2 rotate synchronously.

[0048] Therefore, during the movement of the cutter 2, the slider 6 and the groove 7 can limit the movement of the cutter 2, so that the cutter 2 can rotate synchronously when the cutting roller 301 rotates.

[0049] Furthermore, a positioning structure is provided on the corresponding slider 6 to fix the position of the slider 6 in the slide groove 7. The positioning structure includes a connecting chamber 12 opened inside the slider 6, a support plate 10 is provided inside the connecting chamber 12, a spring 11 is provided between the support plate 10 and the connecting chamber 12, a positioning rod 8 is provided on the support plate 10, and at least two positioning grooves 9 located on the cutting roller 301 are opened on the inner wall of the slide groove 7. The end of the positioning rod 8 away from the support plate 10 passes through and extends into the interior of the positioning groove 9, and the positioning rod 8 is slidably connected inside the positioning groove 9.

[0050] In a specific embodiment, such as Figure 1-3 As shown, the groove 7 is disposed on the outer side of the cutting roller 301 along the x-axis direction. A slider 6 is slidably connected inside the groove 7. The slider 6 is fixed to the inner peripheral wall of the cutter 2, and the width of the slider 6 is adapted to the width of the inner cavity of the groove 7. Furthermore, in order to enable the slider 6 to be positioned more quickly within the groove 7 after its position is adjusted, a positioning structure is provided on the slider 6 to fix its position.

[0051] Specifically, such as Figure 1-3 As shown, the positioning structure includes a connecting chamber 12 inside the slider 6, a support plate 10 slidably connected inside the connecting chamber 12, a spring 11 fixed between the support plate 10 and the connecting chamber 12, a positioning rod 8 fixed on the side of the support plate 10 away from the cutter 2, and at least two positioning grooves 9 located on the cutting roller 301 opened on the inner side wall of the slide groove 7. The end of the positioning rod 8 away from the support plate 10 passes through and extends into the interior of the positioning groove 9, and the positioning rod 8 is slidably connected inside the positioning groove 9.

[0052] Therefore, after the cutter 2 is positioned, the elastic force of the spring 11 can press the positioning rod 8 tightly against the positioning groove 9. The position of the cutter 2 is positioned by the cooperation of the positioning rod 8 and the positioning groove 9. Furthermore, the multiple positioning grooves 9 make the distance of the cutter 2 during movement controllable. After the positioning rod 8 moves to correspond with the positioning groove 9, the elastic force of the spring 11 can connect the positioning rod 8 and the positioning groove 9, thereby fixing the position of the slider 6.

[0053] Preferably, the bottom end of the positioning rod 8 can be set as an arc surface, and the positioning groove 9 can be adapted to the arc surface on the positioning rod 8, so that when the cutter 2 moves, the positioning rod 8 can move from the positioning groove 9 to the slide groove 7 and extend into the connecting chamber 12 after the slider 6 moves, through the arc surface on the positioning rod 8 and the positioning groove 9 adapted to the arc surface.

[0054] Please see Figure 4-5In a preferred embodiment of the present invention, the vertical cutting mechanism 3 includes at least one set of upper surface cutting components and lower surface cutting components; the upper surface cutting components and lower surface cutting components are spaced apart along the transmission direction of the worktable 1; and both cutting components are aligned vertically with the openings on the worktable 1.

[0055] Specifically, in the preferred embodiment of the present invention, both the upper surface cutting assembly and the lower surface cutting assembly include guide rollers 303 and cutting rollers 301 arranged vertically at intervals, with a transmission channel between them for the paperboard to pass through.

[0056] In the actual vertical cutting operation of cardboard, the upper surface of the cardboard is cut first, and then the lower surface of the cardboard is cut, under the action of the upper surface cutting component and the lower surface cutting component that are set at intervals.

[0057] Furthermore, with the cooperation of guide roller 303 and cutting roller 301, the cutting work on the upper and lower surfaces of the cardboard is completed.

[0058] In a specific embodiment, such as Figure 1 As shown, the cutting roller 301 and guide roller 303 in the upper surface cutting assembly are respectively located above and below the transmission channel, while the cutting roller 301 and guide roller 303 in the lower surface cutting assembly are respectively located below and above the transmission channel.

[0059] Furthermore, the vertical height of the guide roller 303 and the cutting roller 301 located inside the opening of the workbench 1 is greater than the plane height of the workbench 1, so that the cardboard can be tilted after entering the transmission channel.

[0060] Therefore, during the vertical cutting of the cardboard, the lower guide roller 303 and the cutting roller 301, which are higher than the plane of the worktable 1, can cause the cardboard to tilt upwards when it is cut by the upper surface cutting component, so that the upper cutter 2 can move deeper into the cardboard, thereby improving the cutting effect of the upper cutter 2 on the cardboard. When the cardboard is cut by the lower surface cutting component, it tilts downwards, so that the lower cutter 2 can move deeper into the cardboard, thereby improving the cutting effect of the lower cutter 2 on the cardboard.

[0061] More specifically, the cutter 2 is mounted on the cutting roller 301. Corresponding to the cutter 2, a groove 302 is provided on the guide roller 303. There are no fewer than two grooves 302, which are linearly and equidistantly distributed on the guide roller 303. The cutter 2 is vertically aligned with the corresponding groove 302. When the cutter 2 rotates, it can be embedded in the corresponding groove 302 to compress the corrugated cardboard before vertical cutting.

[0062] Preferably, when the cutter 2 cuts the cardboard, the cutter 2 first squeezes the cardboard into the corresponding groove 302, and then cuts the cardboard under the pressure of the cutter 2 in conjunction with the groove 302, so as to improve the cutting effect of the cardboard.

[0063] Please see Figure 6 In a preferred embodiment of the present invention, in order to cut the middle layer of the cardboard, the transverse cutting mechanism 5 in the preferred embodiment of the present invention includes a cutting blade 502 mounted on the worktable 1; its axial direction is perpendicular to the worktable 1 in the vertical direction, and it is used to cut the middle layer of the corrugated cardboard in the transverse direction.

[0064] In the actual cutting process, the cardboard can be cut horizontally first using the cutting blade 502 to facilitate subsequent vertical cutting.

[0065] Furthermore, in order to adjust the position of the cutting blade 502 on the worktable 1, the transverse cutting mechanism 5 includes a moving block 503 disposed on the worktable 1.

[0066] Furthermore, the transverse cutting mechanism 5 includes a first motor 504 mounted on the moving block 503, and a cutting blade 502 mounted on the output shaft of the first motor 504; and there is a gap between it and the top of the worktable 1.

[0067] Specifically, by setting the cutting disc 502 on the plane of the worktable 1, the cutting disc 502 can correspond to the middle structural layer of the cardboard when performing the cutting operation.

[0068] In a specific embodiment, such as Figure 1 As shown, the transverse cutting mechanism 5 includes a movable block 503 slidably connected to the upper surface and moves linearly along the x-axis on the worktable 1. The movable block 503 has an installation port 501 for accommodating the cutting disc 502 inside. A first motor 504 is fixed on the upper surface of the movable block 503. The cutting disc 502 is fixed to the outside of the output shaft of the first motor 504 by a drive rod.

[0069] Furthermore, when the cardboard is cut laterally by the transverse cutting mechanism 5, the degree of transverse cutting can be controlled by adjusting the depth of the cutting blade 502 embedded in the cardboard.

[0070] Specifically, when adjusting the position of the cutting disc 502, the position of the moving block 503 on the worktable 1 can be adjusted by connecting the positioning plate with different lower grooves 302, thereby realizing the adjustment of the position of the cutting disc 502.

[0071] Furthermore, a linear module connected to the moving block 503 can be installed on the top surface of the worktable 1 to drive the moving block 503 to move along the x-axis on the worktable 1.

[0072] In one specific embodiment, at least one mounting port 501 is sequentially provided on the moving block 503 along the cardboard conveying direction, and a cutting blade 502 with its axis direction perpendicular to the worktable 1 is assembled in the mounting port 501. There are at least two cutting blades 502 arranged sequentially, and their thickness increases sequentially.

[0073] Specifically, by sequentially arranging no fewer than two cutting blades 502 with progressively increasing thickness along the cardboard conveying direction, the thinner cutting blade 502 can first cut the middle layer of the cardboard, and then the thicker cutting blade 502 can destroy the middle layer of the cardboard, thereby reducing the thickness during subsequent vertical cutting and improving the cutting effect.

[0074] Please see Figure 7 In a preferred embodiment of the present invention, an independent driving mechanism 4 is provided for the upper surface cutting component and the lower surface cutting component respectively; the driving mechanism 4 includes a second motor 405; the output shaft of the second motor 405 is connected to the rotating rod 402 of the guide roller 303 or the cutting roller 301, so that when the second motor 405 is working, it can drive the two rotating rods 402 located on the same y-axis and the guide roller 303 and the cutting roller 301 on their surfaces to move towards each other.

[0075] In a specific embodiment, such as Figure 1 As shown, the drive mechanism 4 also includes four rotating rods 402 arranged along the x-axis direction. The four rotating rods 402 are divided into upper and lower groups. The cutting roller 301 and guide roller 303 located below the transmission channel are mounted on the worktable 1 through the two lower rotating rods 402. The two rotating rods 402 in each group are distributed on the same y-axis. The outer side of one group of rotating rods 402 is respectively provided with a driving wheel 404 and a driven wheel 403. The driving wheel 404 is fixed to the outer side of the output shaft of the second motor 405. The driving wheel 404 and the driven wheel 403 are connected by belt drive.

[0076] In one specific embodiment, a gear is provided on the outer periphery of the output shaft of the second motor 405; when the output shaft of the second motor 405 is directly connected to one of the rotating rods 402, a driven gear is provided on the other rotating rod 402 and meshes with the gear on the output shaft of the second motor 405. Thus, in use, the second motor 405 can simultaneously drive the two rotating rods 402 located on the same y-axis and the guide roller 303 and cutting roller 301 on the surface to move towards each other.

[0077] Furthermore, in order to accommodate corrugated cardboard of different thicknesses, the vertical height of the transmission channel, i.e. the vertical distance between the cutting roller 301 and the guide roller 303, is adjusted. The drive mechanism 4 also includes cylinders 406 that are symmetrically distributed on the left and right sides of the upper surface of the worktable 1. The same mounting frame 401 is fixed on the outer side of the output shaft of the two sets of cylinders 406. The cutting roller 301 and the guide roller 303 located above the transmission channel are mounted on the mounting frame 401 through two upper rotating rods 402.

[0078] Specifically, when the drive mechanism 4 drives the vertical cutting mechanism 3 to vertically cut the cardboard, the second motor 405 operates, and in conjunction with the drive wheel 404 and the driven wheel 403, the lower cutting roller 301 and guide roller 303 can rotate. When the vertical cutting mechanism 3 vertically cuts the cardboard, the cardboard will move into the transmission channel. Under the action of the cylinder 406, the upper cutting roller 301 and guide roller 303 will move towards the worktable 1, and the upper and lower cutting rollers 301 and guide roller 303 will clamp the cardboard. The rotation of the lower cutting roller 301 and guide roller 303 can cause the upper cutting roller 301 and guide roller 303 to rotate under the action of the cardboard. The cardboard is also transmitted and cut by the rotating cutting roller 301 and guide roller 303.

[0079] The working principle of the above embodiments is as follows:

[0080] (1) When it is necessary to cut the cardboard, place the cardboard on the workbench 1 and make the cardboard abut against the moving block 503. Then push the cardboard to move along the y-axis. As the cardboard moves, the cardboard will contact the cutting blade 502. The cutting blade 502 is driven to rotate by the first motor 504. As the cardboard is pushed, the middle layer of the cardboard will contact the high-speed rotating cutting blade 502. The high-speed rotating cutting blade 502 will destroy the middle layer of the cardboard so that the cardboard can be cut through in subsequent vertical cutting. The position of the moving block 503 on the workbench 1 can be adjusted by the cooperation of the positioning plate and the lower groove 302.

[0081] As the cardboard is pushed, the middle layer of the cardboard is broken. After the cardboard is pushed into the upper surface cutting assembly, the cylinder 406 operates and the output shaft retracts. The cylinder 406 drives the mounting frame 401 to move downward. As the mounting frame 401 moves, the cutting roller 301 and guide roller 303 inside the mounting frame 401 also move downward. At the same time, the second motor 405 runs and drives the drive wheel 404 to rotate through the lower rotating rod 402. The drive wheel 404 then drives the driven wheel 403 to rotate through the belt drive, so that the two lower connecting rods rotate. After the two lower rotating rods 402 rotate, the lower cutting roller 301 and guide roller 303 also rotate.

[0082] (2) After the cutting roller 301 drives the cutter 2 to contact the cardboard, it will squeeze the cardboard into the groove 302 in the guide roller 303. With the cooperation of the cutter 2 and the groove 302, the upper surface of the cardboard will be cut. When the cardboard enters the left conveying space from the worktable 1, the cardboard will be tilted, so that the cardboard can tilt upward and downward respectively when entering the upper surface cutting component and the lower surface cutting component. This allows the upper cutter 2 to move deeper into the cardboard, thereby improving the cutting effect of the upper cutter 2 on the cardboard. After the cardboard enters the lower surface cutting component, the cardboard will enter the right conveying space and contact the upper groove 302 and the lower cutter 2. The lower surface of the cardboard can be cut by the cooperation of the upper groove 302 and the lower cutter 2. After the cardboard enters the worktable 1 from the right conveying space, the cardboard will tilt towards the worktable 1, so that the lower cutter 2 can move deeper into the cardboard, thereby improving the cutting effect of the lower cutter 2 on the cardboard.

[0083] Simultaneously, the position of the cutter 2 needs to be adjusted. When cutting cardboard of different specifications, the position of the cutter 2 on the cutting roller 301 can be adjusted. During adjustment, the cutter 2 is pushed to move on the cutting roller 301. After the cutter 2 moves, the slider 6 can move in the groove 7. Through the external pushing force applied to the cutter 2, and under the action of the positioning groove 9 and the positioning rod 8, the positioning rod 8 can move from the corresponding positioning groove 9 into the connecting chamber 12. After the positioning rod 8 moves, it will also compress the spring 11 through the support plate 10. The spring 11 contracts, and as the cutter 2 moves, the bottom end of the positioning rod 8, which enters the connecting chamber 12, also moves within the slide groove 7. After the slider 6 moves the positioning rod 8 to the next positioning groove 9, the positioning rod 8 moves back into the positioning groove 9. The spring 11 is no longer under force and rebounds to its original position. Under the elastic force of the spring 11, the positioning rod 8 is also tightly fixed within the positioning groove 9. By connecting the positioning rod 8 with different positioning grooves 9, the position of the cutter 2 can be adjusted so that the cutter 2 can cut cardboard of different specifications.

[0084] Based on this, the present invention also provides an operation method for a corrugated cardboard processing and cutting device, which is implemented using the corrugated cardboard processing and cutting device equipment in the above preferred embodiment, and includes the following steps:

[0085] S1: Place the cardboard on workbench 1 and transfer the cardboard along the x-axis;

[0086] S101: When the cardboard is being transported, the cardboard is attached to the moving block 503, and the moving block 503 positions the cardboard during transport.

[0087] S2: During the transfer of the cardboard, the cardboard first comes into contact with the transverse cutting mechanism 5. Under the action of the rotating cutting blade 502, the middle layer of the cardboard can be cut.

[0088] S201: After the cardboard is conveyed to contact the cutting blade 502, the first motor 504 drives the cutting blade 502 to rotate;

[0089] S202: The rotating cutting blade 502 corresponds to the middle layer of the cardboard during transmission and cuts and destroys the middle layer of the cardboard;

[0090] S3: The vertical cutting mechanism 3 is driven by the drive mechanism 4 to vertically cut the cardboard;

[0091] S301: After the second motor 405 starts running, the cutting roller 301 and the guide roller 303 can be rotated by the rotating rod 402;

[0092] S4: After the middle layer of the cardboard is cut, the cardboard in the transmission will enter the vertical cutting mechanism 3, and the upper surface cutting component and the lower surface cutting component in the vertical cutting mechanism 3 will cut the upper surface and the lower surface of the cardboard in sequence.

[0093] S401: After the paperboard enters the conveying channel, the upper surface of the paperboard is first cut by the cutting roller 301 and guide roller 303 in the upper surface cutting assembly;

[0094] S402: The cardboard entering the upper surface cutting assembly will be tilted to improve the cutting effect on the upper surface of the cardboard;

[0095] S403: After the upper surface of the cardboard is cut, the cardboard will enter the lower surface cutting assembly;

[0096] S404: The cardboard entering the lower surface cutting assembly will be tilted, and the upper surface of the cardboard will be cut by the cutting roller 301 and guide roller 303 in the lower surface cutting assembly to improve the cutting effect on the lower surface of the cardboard.

[0097] S5: When vertically cutting cardboard, the position of cutter 2 can be adjusted to cut cardboard of different specifications;

[0098] S501: When the slider 6 moves within the slide groove 7, the position of the cutter 2 can be adjusted;
