Description

Technical Field

[0001] This invention relates to the field of cardboard cutting equipment technology, specifically to a high-precision cardboard cutting and processing equipment with adjustable distance. Background Technology

[0002] Corrugated cardboard is a multi-layered adhesive, consisting of at least one layer of corrugated core paper and one layer of cardboard. It has high mechanical strength and can withstand collisions and drops during handling. Corrugated cardboard requires cutting during production, and the cutting equipment used varies depending on the process.

[0003] Common corrugated cardboard thicknesses include 3mm, 5mm, 7mm, 9mm and above. Thick corrugated cardboard is mainly used for packaging, transporting machinery, equipment and other heavy goods. The diameter of the holes on this type of corrugated cardboard is larger. When the cutting scissors descend to contact the corrugated cardboard during the cutting process, the holes are easily bent, causing deformation at the cut edge of the corrugated cardboard. This significantly reduces the protective ability of the corrugated cardboard edges.

[0004] To address the aforementioned technical problems, the applicant has retrieved some existing technologies to prevent the edges of corrugated paper from deforming due to compression during cutting. For example, patent application publication number CN112936376A primarily employs two guide cutting ports to cut the support plates at the upper and lower ends of the corrugated paper core, achieving targeted cutting of the corrugated cardboard. Simultaneously, a pressure roller is inserted into the through-hole in the center of the corrugated paper core and rolls inside, providing support for the cutting position. However, the applicant's analysis reveals a drawback to this technical solution: the cutting position of the blade assembly varies depending on the cutting size. When the cut is made at the crest of the middle layer of corrugated paper, the holes under the crest need to be precisely supported to prevent the blade assembly from flattening the holes as it descends, thus reducing the protective performance at that point. However, in existing technologies, longitudinal support is used when making lateral cuts, which can easily cause the edges of the holes under the crest to curl up, resulting in wrinkles at the cut. Once wrinkles appear, they will exacerbate the deformation at the cut, and the holes around the cut will also be subjected to varying degrees of compression deformation, resulting in a significant reduction in the protective performance around the cut. Based on this, the present invention provides a smart water meter with a simple and ingenious structure that can monitor water seepage from the source and automatically alarm for leaks. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a high-precision cardboard cutting and processing equipment with adjustable distance, thereby solving the technical problem that large areas of holes around the cutting point are prone to deformation due to the difference between the cutting direction and the support direction.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A high-precision cardboard cutting and processing device with adjustable distance includes:

[0008] A base on which a conveyor for conveying a limiting plate is mounted, on which a cardboard to be cut is placed, and a cutting assembly for cutting the cardboard on the limiting plate is mounted on the base.

[0009] A support assembly, corresponding to a corrugation on the cardboard located below the cutting assembly, comprises several support blocks with gaps between adjacent blocks. Each support block is slidably connected to a positioning rod, and the support blocks are elastically connected to the positioning rod via several elastic elements. The positioning rod is fixedly mounted on a base. When the elastic elements are in a free state, the top of the support block contacts the bottom surface of the corrugation below the cutting assembly.

[0010] The transmission component is mounted on the limiting plate. When the limiting plate is transported to the bottom of the cutting component, the transmission component drives the support block to descend until the support block enters the hole under the corrugation of the cardboard. When the support block descends to the bottom of its movement path, the bottom of the support block is above the bottom paper of the cardboard, and there is a gap between the two.

[0011] As a further aspect of the present invention: multiple support components are provided, and the multiple support components are respectively aligned with the holes below the multiple crests on the cardboard.

[0012] As a further aspect of the present invention, the support block is provided with a plurality of slits that cooperate with the cutting component.

[0013] As a further aspect of the present invention: the transmission assembly includes a bracket fixed to the limiting plate and a pressure rod rotatably mounted on the bracket, and the pressure rod contacts the support block before the cardboard on the limiting plate; when the cardboard on the limiting plate moves to contact the support block, the pressure rod presses the support block, the support block descends, the elastic element deforms, until the pressure rod moves away from the support block, at which point the support block is located in the hole below the crest, and after the support block resets, it contacts the bottom surface of the crest.

[0014] As a further aspect of the present invention: the transmission assembly further includes a limiting strip fixed to the limiting plate, and the limiting strip is aligned with the hole below the crest at the edge of the cardboard.

[0015] As a further aspect of the present invention: the transmission assembly further includes a support plate fixed to the limiting plate. The support plate is made of elastic material and is located below the pressure rod. When the pressure rod pushes the support block down, the support block pushes the support plate, and the adjacent support blocks of the support block contact the support plate.

[0016] As a further aspect of the present invention: the support assembly further includes side support rods made of magnetic material. A side support rod is rotatably installed on each side of the support block, and the two side support rods repel each other magnetically. When the support block slides down the positioning rod, the positioning rod pushes the two side support rods to flip until they are in contact with the side wall of the support block.

[0017] As a further aspect of the present invention: the cutting component includes:

[0018] A shaft body is slidably mounted on a base, and two blades are rotatably mounted on it; the number of the shaft bodies is two.

[0019] A first drive module, mounted on a base, comprises two modules corresponding to two shafts respectively, and each module is connected to a blade. These modules are used to adjust the distance between the two blades on the shaft and to drive the blades to rotate.

[0020] The second drive module is mounted on the base and connected to both shafts. It is used to adjust the distance between the two shafts and drive the shafts to rise and fall.

[0021] The beneficial effects of this invention are:

[0022] (1) In this invention, when the limiting plate conveys the cardboard to the bottom of the cutting component, the transmission component drives the support block to descend. There is a gap between the top of the support block and the bottom surface of the wave crest below the cutting component. At the same time, there is a gap between the bottom of the support block and the top surface of the bottom paper of the cardboard. This allows the support block to pass smoothly through the hole below the wave crest on the cardboard. When the cutting component descends, if the cutting position is the surface of the wave crest on the cardboard, the support block can accurately support the hole below the wave crest, avoiding the cutting component from squeezing the wave crest, causing the hole below the wave crest to deform and collapse, thus causing wrinkles at the cutting point. Furthermore, the cutting component performs longitudinal cutting, and the support block provides longitudinal support to the wave crest, which can avoid the problem of large-area holes around the cutting point deforming due to the different cutting direction and support direction.

[0023] (2) In this invention, multiple support components can simultaneously support the holes under multiple crests of the cardboard on the limiting plate. When the cutting component presses down to cut, the matrix formed by multiple support blocks can further prevent large-area collapse and deformation of the holes around the cutting point.

[0024] (3) In this invention, when the pressure rod squeezes the support block down, the positioning rod pushes the two side support rods to flip until they are in contact with the side wall of the support block, that is, the two side support rods retract, which can prevent the support block from accidentally damaging the side wall of the hole when it is inserted into the hole; when the support block separates from the pressure rod, the support block is located in the hole below the wave crest. The support block resets to support the bottom surface of the wave crest, and at the same time, the two side support rods reset under the action of magnetic repulsion to support the side wall of the hole, thereby improving the firmness of the hole support.

[0034] 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.

[0035] Please see Figures 1-7As shown, this invention is a high-precision paperboard cutting and processing device with adjustable distance, comprising:

[0036] A base 1 is provided with a conveyor 2 for conveying a limiting plate 3, on which a cardboard to be cut is placed. A cutting assembly 4 for cutting the cardboard on the limiting plate 3 is also provided on the base 1.

[0037] A support assembly, corresponding to the crest on the cardboard located below the cutting assembly 4, includes several support blocks 5 with gaps between adjacent blocks 5. Each support block 5 is slidably connected to a positioning rod 6, and the support blocks 5 are elastically connected to the positioning rod 6 via several elastic elements. The positioning rod 6 is fixedly mounted on the base 1. When the elastic elements are in a free state, the top of the support block 5 contacts the bottom surface of the crest below the cutting assembly 4.

[0038] The transmission component 7 is installed on the limiting plate 3. When the limiting plate 3 is transported to the bottom of the cutting component 4, the transmission component 7 drives the support block 5 to descend until the support block 5 enters the hole under the corrugation of the cardboard. When the support block 5 descends to the bottom of its movement path, the bottom of the support block 5 is above the bottom paper of the cardboard, and there is a gap between the two.

[0039] Specifically, the bottom of the support block 5 is provided with a locking block, which cooperates with the locking groove provided at the bottom of the positioning rod 6, and the locking block and the locking groove are connected by an elastic element; the elastic element can be a spring, or other elastic components can be used instead, such as silicone pillars, spring sheets, etc., which are not specifically limited in this embodiment; the conveyor 2 includes a conveyor belt and a driving component, which are existing technologies and have not been improved in this application. Therefore, it is not necessary to disclose its specific mechanical structure and circuit structure, and it does not affect the integrity of this application.

[0040] It should be noted that the elastic element is in a free state, that is, the elastic element is not subject to external force. At this time, the top of the support block 5 contacts the bottom surface of the crest below the cutting component 4, and the two abut against each other. In addition, there are gaps between the multiple support blocks 5, and the cutting component 4 aligns with the gaps when it descends to cut. At the same time, the support blocks 5 are made of elastic materials, specifically, sponge or rubber and other elastic materials can be used. When the cutting component 4 contacts the cardboard to cut, the cutting component 4 contacts two adjacent support blocks 5 and squeezes the support blocks 5 to deform until the cutting component 4 descends to contact the bottom paper of the cardboard and cuts the bottom paper in the gap. The specific size of the gap can be designed according to the size of the cutting end of the cutting component 4, which will not be elaborated here. Of course, in actual use, the size of the cutting end can also be set to be smaller than the gap length between two adjacent support blocks 5, as long as the cutting component 4 can penetrate the cardboard to cut. No specific limitation is made here.

[0041] In one embodiment, the feeding end of the base 1 is detachably connected to a baffle 10, which can limit the movement of the cardboard before cutting; the baffle 10 can also be removed to connect the feeding end of the base 1 to a collecting device to collect the cut cardboard, without specific limitations here; the baffle 10 and the base 1 can be connected by bolts, or a snap-fit ​​assembly method can be used, without further details here.

[0042] In practical application, the elastic element is initially in a free state. At this time, the top height of the support block 5 is the same as the bottom height of the corrugation below the cutting component 4. When the limiting plate 3 conveys the cardboard to the bottom of the cutting component 4, the transmission component 7 drives the support block 5 to descend. There is a gap between the top of the support block 5 and the bottom surface of the corrugation below the cutting component 4. At the same time, there is a gap between the bottom of the support block 5 and the top surface of the bottom paper of the cardboard. This allows the support block 5 to pass smoothly through the holes below the corrugations on the cardboard. Subsequently, when the cutting component 4 descends, if the cutting position is the surface of the corrugations on the cardboard, the support block 5 can accurately support the holes below the corrugations, preventing the cutting component 4 from squeezing the corrugations and causing the holes below the corrugations to deform and collapse, thus causing wrinkles at the cutting point. Furthermore, the cutting component 4 performs longitudinal cutting, and the support block 5 provides longitudinal support to the corrugations, which can prevent the large area of ​​holes around the cutting point from deforming due to the different cutting and support directions.

[0043] like Figures 1-3 As shown, in a preferred embodiment of the present invention, multiple support components are provided, and the multiple support components are respectively aligned with the holes below the multiple crests on the cardboard.

[0044] In one embodiment, multiple support components are arranged in parallel at equal intervals, and multiple support blocks 5 of the support components are arranged at equal intervals. The multiple support components are arranged horizontally, and the support blocks 5 within them are arranged vertically.

[0045] In practical application, multiple support components can simultaneously support the holes under multiple crests of the cardboard on the limiting plate 3. When the cutting component 4 presses down to cut, the matrix formed by multiple support blocks 5 can further prevent large-area collapse and deformation of the holes around the cutting point.

[0046] like Figures 4-6 As shown, in a preferred embodiment of the present invention, the support block 5 is provided with a plurality of cuts 9 that cooperate with the cutting component 4.

[0047] In practical applications, when the cutting component 4 descends and contacts the cardboard for cutting, the cut 9 can be adapted to the cutting end of the cutting component 4, reducing damage to the support block 5 caused by the cutting end.

[0048] like Figures 3-6 As shown, in a preferred embodiment of the present invention, the transmission assembly 7 includes a bracket 701 fixed on the limiting plate 3 and a pressure rod 702 rotatably mounted on the bracket 701. The pressure rod 702 contacts the support block 5 before the cardboard on the limiting plate 3. When the cardboard on the limiting plate 3 moves to contact the support block 5, the pressure rod 702 presses the support block 5, causing the support block 5 to descend and the elastic element to deform until the pressure rod 702 moves away from the support block 5. At this time, the support block 5 is located in the hole below the crest. After the support block 5 is reset, it contacts the bottom surface of the crest.

[0049] In practical application, when the conveyor 2 moves the limiting plate 3 to a position about to contact the support block 5, the pressure rod 702 first contacts the support block 5. Since the height of the pressure rod 702 is lower than the top height of the support block 5 in its free state, the pressure rod 702 presses the support block 5 downwards, causing relative sliding between the support block 5 and the positioning rod 6. At this time, the top height of the support block 5 is lower than the height of the lowest point of the wave crest, preventing wear on the wave crest when the support block 5 is inserted into the hole to support it, or misalignment and impact with the wave crest, thus improving the safety and accuracy of the support function during device use. After the pressure rod 702 moves away from the support block 5, the elastic element resets, causing the support block 5 to reset. The support block 5 can then contact the top of the hole below the wave crest, thus supporting the wave crest and preventing the hole from collapsing due to the descending pressure during cutting.

[0050] like Figures 1-5 As shown, in a preferred embodiment of the present invention, the transmission component 7 further includes a limiting strip 703 fixed on the limiting plate 3, and the limiting strip 703 is aligned with the hole below the crest at the edge of the cardboard.

[0051] In practical application, when placing cardboard on the limiting plate 3, align the hole below the crest at the edge of the cardboard with the limiting strip 703, and insert the limiting strip 703 into the hole. Then, the supporting blocks 5 can be aligned with the holes below the crests, thereby providing precise support for each crest.

[0052] like Figures 2-5 As shown, in a preferred embodiment of the present invention, the transmission assembly 7 further includes a support plate 704 fixed on the limiting plate 3. The support plate 704 is made of elastic material and is located below the pressure rod 702. When the pressure rod 702 presses the support block 5 down, the support block 5 presses the support plate 704, and the adjacent support block 5 contacts the support plate 704.

[0053] In one embodiment, the support plate 704 can be made of sponge, or other elastic materials such as rubber, without specific limitations.

[0054] In practical application, when the pressure rod 702 presses the support block 5 down, the support block 5 simultaneously presses the support plate 704 to deform. At the same time, the adjacent support block 5, that is, the support block 5 located outside the cardboard hole, comes into contact with the support plate 704. The elastic force of the support plate 704 to recover its deformation can ensure that the support block 5 about to enter the hole can be smoothly reset. At the same time, it can prevent the support block 5 outside the hole from being pulled down when it descends, ensuring that the support block 5 can accurately enter the hole and provide precise support for the crest.

[0055] like Figure 6 As shown, in a preferred embodiment of the present invention, the support assembly further includes side support rods 8 made of magnetic material. A side support rod 8 is rotatably installed on each side of the support block 5, and the two side support rods 8 repel each other magnetically. When the support block 5 slides up and down the positioning rod 6, the positioning rod 6 pushes the two side support rods 8 to flip until they are in contact with the side wall of the support block 5.

[0056] In practical application, the angle between the two side support rods 8 on the support block 5 is at its maximum in the initial state. When the pressure rod 702 pushes the support block 5 down, the positioning rod 6 pushes the two side support rods 8 to flip until they fit against the side wall of the support block 5, that is, the two side support rods 8 retract, which can prevent the support block 5 from accidentally damaging the side wall of the hole when it is inserted into the hole. When the support block 5 separates from the pressure rod 702, the support block 5 is located in the hole below the crest. The support block 5 resets to support the bottom surface of the crest, and at the same time, the two side support rods 8 reset under the action of magnetic repulsion to support the side wall of the hole, thereby improving the stability of the hole support.

[0057] like Figures 1-7 As shown, in a preferred embodiment of the present invention, the cutting component 4 includes:

[0058] A shaft 401 is slidably mounted on a base 1, and two blades 402 are rotatably mounted on it. The number of shafts 401 is two.

[0059] A first drive module 403 is mounted on a base 1. Two first drive modules 403 correspond to two shafts 401 respectively, and the first drive modules 403 are connected to blades 402. They are used to adjust the distance between the two blades 402 on the shafts 401 and to drive the blades 402 to rotate.

[0060] The second drive module 404 is mounted on the base 1 and connected to both shafts 401. It is used to adjust the distance between the two shafts 401 and drive the shafts 401 to rise and fall.

[0061] In one embodiment, the first drive module 403 includes a motor assembly, or a gear assembly or pulley assembly driven by a motor, as long as it can make the blade 402 rotate. No specific limitation is made here. It also includes a hydraulic cylinder or other mechanism that can realize linear motion and drive the two blades 402 to translate. No specific limitation is made here in this embodiment. The second drive module 404 includes a hydraulic cylinder or other mechanism that can realize linear motion and drive the shaft 401 to translate.

[0062] In practical applications, this embodiment can adjust the position of the blade 402 and the spacing between adjacent blades 402 by using the first drive module 403 in conjunction with the second drive module 404, thereby adapting to different cutting requirements.

[0063] Working principle of the invention: The above embodiments of the invention provide a high-precision paperboard cutting and processing device with adjustable distance. When the limiting plate 3 conveys the paperboard to the area below the cutting component 4, the transmission component 7 drives the support block 5 to descend. There is a gap between the top of the support block 5 and the bottom surface of the wave crest below the cutting component 4, and at the same time, there is a gap between the bottom of the support block 5 and the top surface of the bottom paper of the paperboard. This allows the support block 5 to pass smoothly through the holes below the wave crest on the paperboard. Subsequently, when the cutting component 4 descends, if the cutting position is the surface of the wave crest on the paperboard, the support block 5 can accurately support the holes below the wave crest, avoiding the cutting component 4 from squeezing the wave crest, which would cause the holes below the wave crest to deform and collapse, resulting in wrinkles at the cutting point. Furthermore, the cutting component 4 performs longitudinal cutting, and the support block 5 provides longitudinal support for the wave crest, which can avoid the problem of large-area deformation of the holes around the cutting point due to the different cutting direction and support direction.

[0064] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
