Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to a corrugated board cutting device. 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. The actual performance of corrugated cardboard depends on three factors: the characteristics of the core paper and the cardboard, and the structure of the carton itself.

[0003] Patent document CN219054478U discloses a corrugated cardboard cutting device, including a support plate for placing corrugated cardboard; a cutting blade disposed above the support plate, the cutting blade being driven by an electric push rod; and a first nozzle for spraying air onto the cutting blade. The first nozzle is disposed on a first pipe, to which a second pipe is connected. One end of the second pipe is connected to the air outlet of a fan, and both ends of the first pipe are closed. The first nozzle and the first pipe are in communication, as are the second and first pipes. This invention is convenient and quick to use. The air generated by the fan is delivered to the first nozzle through the second and first pipes, and then blown onto the cutting blade by the first nozzle, effectively blowing away paper scraps adsorbed on the cutting blade and preventing these scraps from affecting the next cut.

[0004] When using the above-mentioned technology, the following technical problems were found in the existing technology: When cutting corrugated cardboard with a cutting blade, due to the lack of a corresponding fixing structure, if the corrugated cardboard is accidentally touched by external force during the cutting process, it is easy to deviate, causing the cutting blade to shift from the pre-cutting position. This not only affects the cutting quality but may even damage the cutting blade. In addition, during the cutting process, paper scraps easily adhere to the blade, affecting the cutting accuracy and increasing cutting resistance, thus accelerating blade wear. Therefore, a corrugated board cutting device is designed to provide an alternative technical solution to the above-mentioned technical problems. Utility Model Content

[0005] Therefore, it is necessary to provide a stable, efficient and easy-to-maintain corrugated cardboard cutting device to address the aforementioned technical problems, thereby solving the issues of easy deviation of corrugated cardboard during the cutting process and the adhesion of paper scraps to the blade.

[0015] In a preferred embodiment of the corrugated board cutting device provided by this utility model, the first base is fixed between one side of the knife holder and the slider of a set of second guide members.

[0020] As a preferred embodiment of the corrugated board cutting device provided by this utility model, the contact part includes a set of brush bristles arranged in a transverse direction and opposite to each other, and a guide plate fixed on the set of brush bristles, the guide plate being inclined with its bottom end gradually approaching the cutting groove.

[0021] The collection section includes a cavity fixed inside the cutting groove and a chip discharge port opened on the cavity;

[0022] The bottom of the cavity forms a chip removal channel that slopes to one side, and the chip removal port is located at the bottom of the chip removal channel.

[0023] It is clear without a doubt that the technical solution described above in this application can solve the technical problem that this application aims to address.

[0024] At the same time, through the above technical solutions, this utility model has at least the following beneficial effects:

[0025] The corrugated board cutting device provided by this utility model can firmly clamp the corrugated board through a fixing mechanism, effectively preventing the corrugated board from shaking or shifting during the cutting process, thereby significantly improving the cutting accuracy and efficiency.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0037] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0038] like Figure 1 As shown, this corrugated board cutting device includes a table 1, a cutting mechanism 2, a set of fixing mechanisms 3, and a cleaning mechanism 4. The table 1 serves as the support platform for the entire device, ensuring stable operation. The cutting mechanism 2 is mounted on the table 1 and is used for precise cutting of the corrugated board. The set of fixing mechanisms 3 are distributed at appropriate positions in the cleaning mechanism 4 to fix the corrugated board, preventing movement during cutting and ensuring cutting accuracy. The cleaning mechanism 4 is located between the table 1 and the cutting mechanism 2 to promptly clean up debris generated during cutting, maintaining a clean working environment and improving work efficiency.

[0039] like Figure 2 As shown, and for reference Figure 1 The cutting mechanism 2 includes a bracket 21 fixed on the table 1, a cutter 24 that can move vertically on the bracket 21 via a set of first guide members 22 and a set of second guide members 23, and a brake member 26 that drives the cutter 24 to move vertically via a cutter holder 25.

[0040] The cutting mechanism 2 further includes a support 21, a set of first guide members 22 and a set of second guide members 23, a cutter 24, a blade holder 25, and a brake 26. Specifically, the support 21 is securely mounted on the table 1, providing a solid foundation for the entire cutting mechanism 2. The set of first guide members 22 is arranged longitudinally along the support 21 to ensure the stability and accuracy of the cutter 24 during vertical movement. The set of second guide members 23 complements the first guide members 22, further enhancing the guiding nature of the cutter 24's movement and reducing deviations during the cutting process. The blade holder 25 is tightly connected to the cutter 24, providing stable support for the cutter 24. The brake 26, by driving the blade holder 25, achieves precise control over the vertical movement of the cutter 24, ensuring cutting accuracy and efficiency.

[0041] Furthermore, since the tabletop 1 has a slot 11 that can accommodate the cutter 24, when the corrugated board is covered by the slot 11, the cutter 24 can accurately cut into the corrugated board as it enters the slot 11, thus completing the cutting operation.

[0042] Based on the above, the cleaning mechanism 4 further includes a contact part 41 and a collection part 42. Specifically, the contact part 41 is fixed to the bracket 21 and is designed to be made of a soft and wear-resistant material so that it can closely adhere to the surface of the cutting mechanism 2 after the cutting mechanism 2 has been operated, especially the path of the cutter 24, thereby effectively removing contaminants such as paper scraps, dust, or glue remaining on the cutter 24. The collection part 42 is located at the bottom of the groove 11, forming a collection chamber. When contaminants removed by the contact part 41 fall, they can be directly received by the collection part 42, preventing contaminants from scattering on the work surface 1 and maintaining a clean working environment. In some embodiments, the collection part 42 is designed to be detachable, making it convenient for users to regularly clean the collected contaminants and maintain the continuous and efficient operation of the cleaning mechanism 4.

[0043] like Figure 3 As shown, and for reference Figure 2 Each of the first guide members 22 is further composed of guide rods 221, and one end of the guide rod 221 passes through the bracket 21 and is fixed to the knife holder 25, thereby ensuring the stability of the knife holder 25 during the cutting process. It not only plays a guiding role, but also effectively prevents the knife holder 25 from shaking due to uneven force, thus ensuring cutting accuracy.

[0044] Each set of second guide members 23 further includes a guide rail 231 and a slider 232. Specifically, the guide rail 231 is a strip structure vertically fixed to the inner side of the bracket 21, with its length direction aligned with the tangent direction, ensuring that the cutter holder 25 can move smoothly along a preset trajectory during the cutting process. The slider 232 is firmly fixed to both ends of the cutter holder 25, with its inner surface closely fitting the outer surface of the guide rail 231, and a sliding connection is used to achieve relative movement between the cutter holder 25 and the guide rail 231. The second guide members 23 further improve the stability and accuracy of the cutter holder 25 during the cutting process. The strip structure design of the guide rail 231 not only enhances its load-bearing capacity but also ensures the straightness of the cutter holder 25 during movement, avoiding cutting quality problems caused by deviation.

[0045] The braking component 26 is further preferably a cylinder 261, which is inverted and fixed in the middle of the bracket 21. This arrangement allows the piston shaft of the cylinder 261 to directly act on the cutter holder 25, providing it with a stable and powerful braking force. That is, the piston shaft of the cylinder 261 passes through the bracket 21 and is firmly fixed to the cutter holder 25, ensuring the effective transmission of braking force. When braking is required, the cylinder 261 responds quickly, and through the extension and retraction of the piston shaft, it achieves rapid and precise braking control of the cutter holder 25, thereby driving the cutter 24 on the cutter holder 25 to cut the corrugated plate located on the cutting groove 11.

[0046] like Figure 4 As shown, and for reference Figure 1 and Figure 2 Each set of fixing mechanisms 3 further includes a first base 31, a pressure body 32, and a limiting member 33; specifically, the first base 31 has a U-shaped structure, with its vertical part located on the side of the cutting mechanism 2 and fixed to one side of the knife holder 25, and its horizontal part extending inward to the side of a set of second guide members 23 and slider 232, thereby providing a stable support point for the subsequent rotation of the pressure body 32 through the connection between the first base 31 and the cutting mechanism 2;

[0047] Based on the above, one end of the pressure body 32 is rotatably connected to the horizontal part of the first base 31 through a pivot pin or other rotatable connector, so that the pressure body 32 can rotate flexibly around the pivot pin.

[0048] The limiting member 33 connects the first base 31 and the pressing body 32. In its natural state, the limiting member 33 keeps the pressing body 32 at a preset first angle, which facilitates the contact between the pressing body 32 and the table surface 1. When the pressing body 32 moves with the tool holder 25 and contacts the table surface 1, it is subjected to the reaction force of the table surface 1, and the pressing body 32 will rotate around the pin. At this time, the limiting member 33 moves and forms a second angle. This angle design allows the pressing body 32 to fit tightly against the table surface 1, achieving effective fixation of the corrugated board.

[0049] The press body 32 includes a plurality of second bases 321 arranged in a vertical direction and rotatably connected to the first base 31 at their top ends, a wheel 322 fixed to the bottom ends of the plurality of second bases 321, and a third base 323 fixed at intervals between the plurality of second bases 321 so that the plurality of second bases 321 are connected as one unit.

[0050] The pressing body 32 further includes multiple second bases 321, multiple wheels 322, and multiple third bases 323. Specifically, the second bases 321 are arranged vertically to ensure that the pressing body 32 has a certain height, so that the wheels 322 and the table surface 1 maintain an appropriate distance, which facilitates the placement and cutting of corrugated sheets. The top of the second base 321 is rotatably connected to the first base 31, which allows the entire pressing body 32 to flexibly adjust its angle to adapt to the fixing requirements of corrugated sheets of different thicknesses.

[0051] The wheel 322 is fixed to the bottom of multiple second bases 321. Its design not only reduces the friction between the pressure body 32 and the table 1, allowing the pressure body 32 to rotate more smoothly when it contacts the table 1, but also ensures that the pressure body 32 is evenly stressed when it is in contact with the table 1, thus enhancing the stability of the fixation.

[0052] The third base 323, which is fixed at intervals between the multiple second bases 321, serves to connect and strengthen the structural strength of the second bases 321. The arrangement of multiple third bases 323 allows the multiple second bases 321 to be connected into a whole, forming a more stable overall structure, which improves the stability and durability of the press body 32 during use.

[0053] The limiting component 33 further comprises multiple tension springs 331, which are evenly distributed between the first substrate 31 and the third substrate 323. This arrangement not only ensures the stability of the pressure body 32 when adjusting the angle, but also, through the elastic force of the tension springs 331, allows the pressure body 32 to automatically adjust and maintain appropriate pressure when adhering to corrugated sheets of different thicknesses, further enhancing the stability and adaptability of the fixation. Simultaneously, the elastic characteristics of the tension springs 331 can also buffer the impact force generated during the cutting process to a certain extent, protecting the corrugated sheet from damage and improving cutting accuracy and efficiency.

[0054] It should be noted that the first angle is the shape in which the first base 31 is not rotated by the tension spring 331; the second angle is the shape in which the first base 31 is rotated by the tension spring 331.

[0055] In both configurations, the pressure body 32 can flexibly adapt to the cutting needs of corrugated sheets of different thicknesses. When the pressure body 32 is at the first angle, it maintains a near right angle with the first substrate 31, so that the pressure body 32 contacts the corrugated sheet first when the cutter 24 moves downward. When cutting corrugated sheets of greater thickness, the pressure body 32 can smoothly rotate to the second angle through the elastic force of the tension spring 331, so that the first substrate 31 and the pressure body 32 form an obtuse angle greater than a right angle, ensuring that the cutting tool and the corrugated sheet always maintain good contact and achieve precise cutting.

[0056] like Figure 5 As shown, and for reference Figure 2 The contact part 41 further includes a set of bristles 411 and a set of guide plates 412. Specifically, a set of bristles 411 is arranged along the transverse direction (i.e., the length direction of the cutter 24) and opposite to each other on both sides of the cutter 24. Both ends of the set of bristles 411 are fixed to the inner sides of the bracket 21 to ensure that the set of bristles 411 can contact the initially unmoved cutter 24. Thus, when the cutter 24I cuts the corrugated board downward, the debris generated by the cutting will adhere to the cutter 24. Subsequently, when the cutter 24 moves upward, the debris on the cutter 24 will be blocked by the bristles 411, thereby effectively removing the debris and dust generated during the cutting process and preventing them from adhering to the cutter 24 and affecting subsequent cutting operations.

[0057] The guide plate 412 is inclined at its bottom, gradually approaching the cutting groove 11. This inclination angle guides debris and dust to slide down into the cutting groove 11, preventing debris from interfering with the cutting tool and maintaining a clean working area. Furthermore, the guide plate 412 is preferably made of a wear-resistant and smooth material, further reducing debris adhesion to its surface and improving cleaning efficiency.

[0058] The collecting part 42 further includes a cavity 421 and a chip discharge port 422 opened on the cavity 421, so that the chips falling into the cutting groove 11 can be effectively collected by the cavity 421 and smoothly discharged through the chip discharge port 422.

[0059] In some embodiments, as shown in the figure, the bottom end of the cavity 421 forms a chip removal channel inclined to one side, and the chip removal port 422 is located at the bottom end of the chip removal channel. This arrangement ensures that the debris in the cavity 421 can smoothly slide down the chip removal channel to the chip removal port 422 under the action of gravity, effectively avoiding the accumulation of debris in the cavity 421 and improving the chip removal efficiency. At the same time, the position of the chip removal port 422 allows the debris to be directly discharged outside the device, further simplifying the chip handling process and improving the overall work efficiency.
