This invention designs the sheet-shaped cutter to vibrate periodically along the thickness direction of the honeycomb core panel. When the cutter moves along a set trajectory, it only contacts the bottom of the honeycomb core panel when it moves downwards to its lowest point, and then immediately moves upwards again, disengaging from the bottom of the honeycomb core panel.

Description

Technical Field

[0001] This invention relates to the field of honeycomb core panel technology, and in particular to a honeycomb core panel cutting mechanism and equipment. Background Technology

[0002] Honeycomb cores are made based on the structure of honeycombs found in nature. They consist of multiple layers of foil-like materials. These multiple layers of foil-like materials are bonded and pressed together in specific locations using specific adhesives and a special process, and then cut and processed to form the honeycomb core.

[0003] The stretched honeycomb core forms a honeycomb core panel, which is a sheet material with a hexagonal mesh structure. It is used as the core layer of the composite board, giving the composite board excellent properties such as high strength, weight reduction, and sound insulation.

[0004] like Figure 1 As shown, the outer contour A of the honeycomb core board formed after the honeycomb core is stretched is usually irregular in shape. In actual use, the outer contour of the honeycomb core board needs to be cut and trimmed according to the specifications B of the composite board.

[0005] In existing technology, a disc cutter is used to cut and trim honeycomb core panels. The disc cutter is fixed on the frame and moves along a set track on the frame under the drive of the drive mechanism to cut the honeycomb core panels.

[0006] The above method has the following problems:

[0007] On the one hand, the cuts are always uneven and have burrs, and there is also the problem of incomplete cutting at the bottom of the honeycomb core board. It is not completely cut off, and the two sides of the cut will stick together, which greatly affects the cutting effect and the product quality cannot be guaranteed.

[0008] On the other hand, the disc cutter must move forward at a very slow speed during cutting. If the speed is too fast, it will be impossible to effectively cut the honeycomb core panel. At the same time, the honeycomb core panel will be moved forward by the forward force of the disc cutter, causing deformation and extremely low cutting efficiency. Summary of the Invention

[0009] In view of this, the purpose of the present invention is to provide a honeycomb core panel cutting mechanism to solve the technical problems of burrs on the cut surface, incomplete cutting, and low cutting efficiency in the prior art when using a disc cutter.

[0010] In view of the above objectives, in a first aspect, the present invention provides a honeycomb core panel cutting mechanism, comprising:

[0012] A vibration drive module is connected to the upper end of the sheet-shaped cutter and is used to drive the sheet-shaped cutter to perform periodic vibrations with adjustable frequency and amplitude along the thickness direction of the honeycomb core board in order to cut the honeycomb core board.

[0013] Preferably, the vibration drive module includes a mounting shaft, and the sheet-like cutter is disposed at the lower end of the mounting shaft; and the height of the portion of the sheet-like cutter protruding outside the mounting shaft is not less than the thickness of the honeycomb core board;

[0014] The vibration drive module is provided with a vibration drive unit and / or a mounting shaft drive unit; the vibration drive unit is connected to the sheet-shaped cutter to drive the sheet-shaped cutter to vibrate periodically along the thickness direction of the honeycomb core board, thereby cutting the honeycomb core board; the mounting shaft drive unit is connected to the mounting shaft to drive the mounting shaft to rotate, thereby adjusting the cutting direction of the sheet-shaped cutter.

[0015] Preferably, one side of the blade-shaped tool has at least one second cutting edge formed upwards along the first cutting edge, and the angle between each cutting edge and the horizontal direction gradually increases from bottom to top. When the second cutting edge comprises multiple segments, the angle between each segment of the second cutting edge and the horizontal direction gradually increases from bottom to top, and the angle between the lowest second cutting edge and the horizontal direction is greater than the angle between the first cutting edge and the horizontal direction.

[0016] Furthermore, the angle between the first blade and the horizontal direction is 0° to 20° (the angle between the first blade and the horizontal direction can be 0° or 20°).

[0017] Preferably, the vibration drive module is provided with a pressure-applying component for pressing against the honeycomb core panel.

[0018] Furthermore, the pressure application component includes:

[0019] An elastic element, one end of which is fixed to the vibration drive module;

[0020] The pressure plate abuts against the other end of the elastic member; the end of the pressure plate near the sheet-shaped cutter is provided with a contact surface for pressing against the honeycomb core board; the contact surface is provided with a cutter groove for the sheet-shaped cutter to pass through.

[0021] Furthermore, the pressure application assembly includes at least two pressure rollers, respectively disposed on both sides of the sheet-like cutter, for pressing against the honeycomb core panel.

[0022] This application also provides a honeycomb core panel cutting device, comprising:

[0023] A movable support, which is connected to a support drive mechanism, and the movable support can move along a set trajectory under the drive of the support drive mechanism;

[0024] The aforementioned cutting mechanism is mounted on the movable support to cut the honeycomb core board along a set trajectory under the action of the support driving mechanism.

[0025] Preferably, the device further includes:

[0026] A honeycomb core panel support platform is used to support honeycomb core panels.

[0027] The movable support spans across the honeycomb core panel support platform and can reciprocate along the length of the honeycomb core panel support platform.

[0028] The movable support is equipped with a guide rail, and the vibration drive module of the cutting mechanism is located on the guide rail and can reciprocate along the width direction of the honeycomb core board support platform on the guide rail.

[0029] Furthermore, the honeycomb core panel support platform is provided with a damping pad layer to dampen the honeycomb core panel placed thereon and prevent the honeycomb core panel from shifting.

[0030] Furthermore, the honeycomb core panel support platform is provided with a hollow support surface, and a negative pressure generating device is provided below the hollow support surface. A thin film is provided on the upper surface of the honeycomb core panel.

[0032] Preferably, the honeycomb core panel support platform is divided into multiple independent cavities, and a control component is provided between the negative pressure generating mechanism and each cavity. By controlling different control components, the negative pressure adsorption effect of different areas on the honeycomb core panel support platform can be controlled.

[0033] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0034] (1) The honeycomb core panel cutting mechanism provided by the present invention, by setting a sheet-shaped cutter, can perform periodic vibration with adjustable frequency and amplitude along the thickness direction of the honeycomb core panel under the drive of the vibration drive module, thereby cutting the honeycomb core panel. When the cutter body moves forward along the set trajectory, the vibration drive module drives the cutter body to reciprocate in the vertical direction. The same position on the honeycomb core panel will undergo several cuts from different parts of the cutter body. Therefore, the cut is very neat, there are no burrs, the cutting is very thorough, there is no adhesion, and the forward speed of the cutter body can also be increased, which improves the cutting efficiency.

[0035] (2) The honeycomb core panel cutting mechanism provided by the present invention designs the blade to vibrate periodically along the thickness direction of the honeycomb core panel. When the blade moves forward along the set trajectory, it will only contact the bottom of the honeycomb core panel when it moves downward to the lowest point. Then the blade moves upward again and disengages from the bottom of the honeycomb core panel. This achieves intermittent contact with the bottom of the honeycomb core panel and prevents the honeycomb core panel from moving forward with it. At the same time, a horizontal or nearly horizontal cutting edge is designed at the bottom of the blade to avoid a cutting blind zone.

[0036] (3) The honeycomb core panel cutting equipment provided by the present invention has improved the flexibility of the cutting tool in cutting the honeycomb core panel by setting a movable bracket to install the cutting tool. The movable bracket drives the sheet-like tool to move, thereby enabling the cutting of any contour.

[0037] (4) The honeycomb core panel cutting equipment provided by the present invention positions the honeycomb core panel based on the pressure component of the cutting mechanism, eliminating the previous positioning structure of pressing the honeycomb core panel by the upper and lower plates, thereby avoiding the deformation or collapse of the honeycomb core panel caused by the pressure force, resulting in finished product defects, and effectively ensuring the cutting effect.

[0038] (5) The honeycomb core panel cutting equipment provided by the present invention positions the honeycomb core panel by setting a damping pad with high friction or a negative pressure conveyor belt, which further improves the cutting effect. Attached Figure Description

[0050] Figure 11 for Figure 10 Top view. Detailed Implementation

[0051] This application provides a honeycomb core panel cutting mechanism, which solves the technical problems of burrs on the cut surface, incomplete cutting, and low cutting efficiency in the prior art when using a disc cutter.

[0052] The technical solution in this application is to solve the above-mentioned technical problems, and the general idea is as follows:

[0053] A honeycomb core panel cutting mechanism was designed, including a vibration drive module and a sheet-shaped blade. The sheet-shaped blade can perform periodic vibrations with adjustable frequency and amplitude along the vertical direction (thickness direction of the honeycomb core panel) under the drive of the vibration drive module, thereby cutting the honeycomb core panel.

[0054] Thus, as the cutter moves along the set trajectory, the vibration drive module drives the cutter to reciprocate vertically. The same location on the honeycomb core board undergoes several cuts from different parts of the cutter, resulting in a very clean cut without burrs, a thorough cut, and no adhesion. Simultaneously, the cutter's forward speed can be increased, improving cutting efficiency. In contrast, with traditional disc cutters, the same location on the honeycomb core board only undergoes one cut, resulting in weaker cutting force.

[0055] On the other hand, as the cutter moves along the set trajectory, it only contacts the bottom of the honeycomb core panel when it reaches its lowest point. Immediately afterwards, the cutter moves upward, disengaging from the bottom of the honeycomb core panel. This achieves intermittent contact with the bottom of the honeycomb core panel, preventing the panel from shifting forward. Furthermore, the cutter's bottom is designed with a horizontal or near-horizontal cutting edge to avoid blind spots. In contrast, with traditional disc cutters, the circular outer contour of the disc cutter's bottom is always in contact with the honeycomb core panel, generating a larger forward force that causes the panel to shift forward and deform.

[0056] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0057] Example 1

[0058] Figure 2 This is a schematic diagram of the overall structure of an exemplary honeycomb core panel cutting mechanism in this embodiment. The honeycomb core panel cutting mechanism includes a vibration drive module 32 and a sheet-shaped cutter 50. The sheet-shaped cutter 50 can perform reciprocating motion with adjustable frequency and amplitude in the vertical direction (thickness direction of the honeycomb core panel) under the drive of the vibration drive module 32, thereby cutting the honeycomb core panel.

[0059] Specifically, the vibration drive module 32 is provided with a mounting shaft 33, and a recessed groove is opened at the end of the mounting shaft 33, and the sheet-shaped cutter 50 is fixed in the groove.

[0060] The vibration drive module 32 is provided with a vibration drive unit, which is connected to the sheet-shaped cutter 50 so that the sheet-shaped cutter 50 can perform reciprocating motion with adjustable frequency and amplitude in the vertical direction, thereby cutting the honeycomb core board 6.

[0061] The vibration drive module 32 is provided with a mounting shaft drive unit, which is connected to the mounting shaft to drive the mounting shaft to rotate, thereby adjusting the cutting direction of the blade 50 and realizing directional adjustment within a controllable angle.

[0062] In one optional embodiment, the vibration drive unit and the mounting shaft drive unit of the vibration drive module 32 are drive motors.

[0063] like Figure 4 As shown, the blade-shaped cutter 50 includes a thin blade body 51, which is formed by grinding and is made of cemented carbide, high-speed steel, or ceramic. The upper end of the blade body 51 is fixed in the groove at the end of the mounting shaft 33 of the vibration drive module 32, and the blade body 51 has a cutting edge formed on one side and the lower end.

[0064] Furthermore, a portion of the blade body 51 ( Figure 2 The upper middle part) is located in the groove at the end of the mounting shaft 33 of the vibration drive module 32, and the other part ( Figure 2 The lower middle part is exposed outside the groove. The height of the part of the cutter body 51 exposed outside the groove is not less than the thickness of the honeycomb core plate 6.

[0065] Depending on the cutting requirements, the cutting edge can be a single piece or composed of multiple straight cutting edges connected sequentially, with the angle between each cutting edge and the horizontal direction increasing progressively from bottom to top. For example, such as... Figure 4 As shown, the blade body 51 has at least a first blade 53 and a second blade 52 arranged sequentially from bottom to top. The first blade 53 is located at the lower end of the blade body 51, and the second blade 52 is located on one side of the blade body 51. The angle α between the first blade 53 and the horizontal direction is smaller than the angle β between the second blade 52 and the horizontal direction.

[0066] The larger the angle α between the first cutting edge 53 and the horizontal direction, the larger the cutting "blind zone" (the triangular shaded area between two cuts) of the stroke. Figure 5 As shown.

[0067] One way to reduce this blind zone is to increase the "overcutting amount", that is, to increase the cutting depth, but this is easy to damage the padding layer at the bottom of the honeycomb core board 6, causing the padding layer to be consumed faster.

[0068] Another method is to reduce the angle α between the first cutting edge 53 and the horizontal direction, such as... Figure 6 As shown, the α setting is relatively small, which enables the end of the blade body 51 to form a small, relatively flat, straight section. The design principle of α is: the first blade 53 is horizontal or nearly horizontal (usually within the range of 0-10°, α can be 0° or 10°). This setting can eliminate or reduce the cutting blind zone of the cutting tool and effectively avoid the problems of incomplete cutting and adhesion of the honeycomb core board.

[0069] For example, such as Figure 7As shown, the blade body 51 is constructed with at least a first blade 53, a second blade 1 52a, and a second blade 2 52b in sequence from bottom to top. The first blade 53 is located at the lower end of the blade body 51, and the second blade 1 52a and the second blade 2 52b are located on one side of the blade body 51. The angles between the first blade 53 and the horizontal direction, the angles between the second blade 1 52a and the horizontal direction, and the angles between the second blade 2 52b and the horizontal direction increase sequentially.

[0070] In another alternative implementation, such as Figure 8 As shown, the first cutting edge 53 is a curved edge, and the angle between the tangent at each point of the curved edge and the horizontal direction increases sequentially from bottom to top.

[0071] The aforementioned mechanism offers high precision in adjusting the flatness of the processed surface and the processing depth. This embodiment of the application ensures good surface flatness by incorporating a pressure-applying component, and achieves precise adjustment of the processing depth through precise control of the vertical movement of the cutting power module.

[0072] Specifically, such as Figure 2 As shown, in some embodiments, the mounting shaft 33 of the vibration drive module 32 is provided with a pressure-applying component for pressing against the honeycomb core plate 6, so as to generate a certain positioning effect on the honeycomb core plate 6 during cutting, and at the same time make the honeycomb core plate at both ends of the blade body flat when the sheet cutter 50 cuts, so as to make the cut neat.

[0073] Specifically, the pressure-applying components include:

[0074] The elastic element 34 is sleeved on the output shaft 33, and one end of the elastic element 34 ( Figure 2 The upper middle part is connected to the output shaft 33; and

[0075] Pressure plate 35, and the other end of the elastic member 34 ( Figure 2 (Middle and lower end) connection.

[0076] One end of the pressure plate 35 near the blade 50 ( Figure 2 The lower middle section has a contact surface 36 for pressing against the honeycomb core panel 6. This contact surface 36 has a groove for the sheet-like cutter 50 to pass through. The contact surface 36 curves upwards at both ends along the traveling direction of the sheet-like cutter 50, forming a transition arc shape. The transition arc shape of the contact surface 36 makes it easier to guide the honeycomb core panel 6 into the contact surface 36, reducing the resistance felt when pressing against the honeycomb core panel 6 during the process.

[0077] In the above embodiments, the elastic element 34 can be a spring. The elastic potential energy of the elastic element 34 should not be too large or too small. If the elastic potential energy is too large, it will cause the honeycomb core plate 6 to deform. If the elastic potential energy is too small, it will not exert a pressing effect on the honeycomb core plate 6. The elastic potential energy of the elastic element 34 should be selected so that the pressure plate 35 just presses against the honeycomb core plate 6.

[0078] In other embodiments, such as Figure 3 As shown, the pressure application assembly can also adopt the following structure: the pressure application assembly includes two pressure rollers 37, which are respectively placed on the front and rear sides of the sheet-shaped cutter 50.

[0079] Specifically, in use, the vibration drive module 32 is mounted on the bracket 31, and the pressure roller 37 is also mounted on the bracket 31. Each of the pressure rollers 37 is connected to the bracket 31 through an elastic element so that the pressure roller 37 can elastically press against the honeycomb core panel 6.

[0080] In other embodiments, the aforementioned pressure plate 35 and pressure roller 37 are present simultaneously to provide a more stable pressing effect on the honeycomb core panel 6.

[0081] When the honeycomb core panel cutting mechanism provided in this embodiment is used, the vibration drive module 32 is mounted on the bracket 31 and can move forward along the set trajectory. When the blade 50 moves forward along the set trajectory, the vibration drive module 32 drives the blade body to reciprocate in the vertical direction. The same position on the honeycomb core panel will undergo several cuts from different parts of the blade body. Therefore, the cut is very neat and there are no burrs. The cutting is very thorough and there is no adhesion. At the same time, the forward speed of the blade body can also be increased, improving the cutting efficiency.

[0082] On the other hand, as the blade cutter 50 moves along the set trajectory, the vibration drive module 32 drives the blade cutter 50 to reciprocate vertically. Only when the cutter body moves downward to the lowest point will it contact the bottom of the honeycomb core panel. Immediately afterwards, the cutter body moves upward and disengages from the bottom of the honeycomb core panel. This achieves intermittent contact with the bottom of the honeycomb core panel, preventing the honeycomb core panel from shifting forward. Simultaneously, a horizontal or near-horizontal cutting edge is designed at the bottom of the cutter body to avoid blind spots during cutting. In contrast, during traditional disc cutter cutting, the circular outer contour of the disc cutter's bottom is always in contact with the honeycomb core panel, which generates a large forward force that causes the honeycomb core panel to shift forward and deform.

[0083] Example 2

[0084] Honeycomb core panels are typically prone to deformation. For example, the aluminum honeycomb core panels used in ceiling aluminum honeycomb composite panels generally have an aluminum foil thickness of less than 0.1 mm, a hexagonal side length of more than 3 mm, and a density of approximately 25 kg / m³ after stretching. 3 ~100kg / m3 Between these, the shape stability is extremely poor.

[0085] In traditional circular blade cutting, the cutting force of the blade always causes the honeycomb core to move forward, resulting in deformation. The solution is to use upper and lower plates to press the honeycomb core panel in place, achieving basic positioning and clamping to prevent deformation. However, controlling the clamping force is difficult. If the clamping force is too low, the honeycomb core panel is easily deflected and forcibly deformed during cutting, failing to achieve the preset contour and creating burrs on the cut edge. If the clamping force is too high, the aluminum foil is easily deformed, causing the honeycomb core to "collapse," affecting the quality of the finished product, resulting in poor cutting effect and low cutting efficiency. Furthermore, specialized clamping plates need to be manufactured according to different cutting contour requirements, leading to high costs and limited versatility.

[0086] Based on the honeycomb core panel cutting mechanism in Embodiment 1, this embodiment designs a honeycomb core panel cutting device. The device positions the honeycomb core panel based on the pressure component of the cutting mechanism, eliminating the need for the previous positioning structure that uses upper and lower plates to press the honeycomb core panel. This avoids deformation or collapse of the honeycomb core panel due to pressure, thus preventing defects in the finished product and effectively ensuring the cutting effect.

[0087] In addition, a movable bracket is designed to mount the cutting tool, which improves the flexibility of the cutting tool in cutting the honeycomb core board, thereby enabling cutting effects with different contours.

[0088] Furthermore, by setting up a damping pad with high friction or a negative pressure conveyor belt to position the honeycomb core panel, the cutting effect is further improved.

[0089] like Figures 9-11 As shown, this embodiment provides a honeycomb core panel cutting device, including:

[0090] The honeycomb core panel support platform 5 is used to support the honeycomb core panel 6 to be cut;

[0091] The movable support 31 is connected to the support drive mechanism and can move along a set trajectory under the drive of the support drive mechanism.

[0092] The cutting mechanism described in Embodiment 1 is mounted on the movable support 31 to cut the honeycomb core board 6 along a set trajectory under the action of the support driving mechanism.

[0093] Furthermore, the movable bracket 31 spans across the honeycomb core panel support platform 5 and can reciprocate along the length direction of the honeycomb core panel support platform 5 under the drive of the bracket drive mechanism. Figure 11 center Y direction).

[0094] The movable support 31 is equipped with a guide rail and a tool drive mechanism. The vibration drive module 32 of the cutting mechanism is located on the guide rail on the movable support 31 and is connected to the tool drive mechanism. Under the drive of the tool drive mechanism, the vibration drive module 32 can slide along the guide rail in the width direction of the honeycomb core board support platform 5. Figure 11 (in the X direction).

[0095] The mounting shaft 33 of the vibration drive module 32 can rotate in a direction perpendicular to the honeycomb core panel support platform 5. Figure 9 (Z-direction) to adjust the cutting direction of the blade 50.

[0096] During use, under the pressure of the cutting mechanism's pressure components, the honeycomb core panel is positioned on the honeycomb core panel support platform 5 and will not shift.

[0097] In one optional embodiment, a damping pad 51 is provided on the honeycomb core panel support platform 5, and the honeycomb core panel 6 is disposed on the damping pad 51, which can further prevent the honeycomb core panel 6 from shifting during the cutting process. For example, the damping pad 51 can be made of felt.

[0098] In another optional embodiment, the honeycomb core panel support platform 5 is provided with a hollow support surface, and a negative pressure generating mechanism is provided below the hollow support surface. The honeycomb core panel 6 is placed on the hollow support surface, and a thin film is provided on the upper surface of the honeycomb core panel 6. When working, the negative pressure generating mechanism generates negative pressure, which adsorbs the thin film, so that the honeycomb core panel located between the thin film and the hollow support surface is adsorbed and adhered to the hollow support surface, which can further prevent the honeycomb core panel 6 from shifting during the cutting process.

[0099] In another alternative implementation, such as Figure 10 As shown, the honeycomb core panel support platform 5 has a hollow support surface, and a negative pressure generating mechanism is set below the hollow support surface. A movable conveyor belt 21 is covered on the hollow support surface, and the honeycomb core panel 6 is placed on the conveyor belt 21.

[0100] During cutting, the negative pressure generating device is activated, creating a negative pressure adsorption effect. The honeycomb core panel 6 is then flatly attached to the conveyor belt 21. At this time, the conveyor belt 21 does not move and serves as a damping pad. When not cutting, the negative pressure generating device stops, the negative pressure adsorption effect is released, and the conveyor belt 21 can move to transport the honeycomb core panel 6.

[0101] It should be noted here that the terms "above" and "below" in the embodiments of this application refer to... Figure 8 The directions shown are explained in the diagram. Figure 10 In the middle, the honeycomb core panel 6 is located above the conveyor belt 21, and the honeycomb core panel support platform 5 is located below the conveyor belt 21.

[0102] In some embodiments, the honeycomb core panel support platform 5 is internally divided into multiple independent cavities. A control valve is provided between the negative pressure generating mechanism and each cavity, and the cavity is connected to the negative pressure generating mechanism in a switchable manner through the control valve. Here, the negative pressure generating mechanism can be an existing mature negative pressure generator. The negative pressure connection port of the negative pressure generator is connected in parallel to multiple cavities through a transfer pipeline. The pipeline between each cavity and the negative pressure generator is controlled by a control valve to control the on / off state. By controlling the on / off state of different control valves, the negative pressure adsorption effect of different areas on the honeycomb core panel support platform 5 can be achieved. When the negative pressure generator is activated, it can generate negative pressure in the required partition cavity. If there is a covering on the upper surface of the corresponding partition, the covering will be adsorbed onto the upper surface of the platform.

[0103] To further facilitate the control of different cavities, a PLC circuit board can be used to program and control the negative pressure adsorption area of ​​the negative pressure generator. For example, the hollow support surface corresponding to multiple cavities on the honeycomb core board support platform 5 is divided into different areas. Each area has one or more cavities. All control valves in the area are opened by external commands, so that the cavities are connected to the negative pressure generator to form the adsorption state of the area.

[0104] In some embodiments, the conveyor belt 21 is made of a breathable material, and a set of conveying rollers is provided on the honeycomb core panel support platform 5. The conveyor belt 21 is driven to move relative to the honeycomb core panel support platform 5 by the set of conveying rollers.

[0105] To further improve the conveying effect of the conveyor belt 21, a conveying roller group can be formed by an active roller 22, a driven roller 23, and a tension roller 24 on the honeycomb core panel support platform 5. The conveyor belt 21 covers the conveying roller group to achieve the conveying effect. The conveyor belt 21 needs to have a uniform thickness to ensure that it does not affect the function of the negative pressure adsorption platform during cutting, and it also needs to have a certain degree of air permeability. To prevent the honeycomb core from easily moving on it during processing, the conveyor belt 21 needs to have a certain degree of roughness and flexibility. Therefore, the material selection of the conveyor belt 21 should follow the following principles: the surface friction coefficient of the conveyor belt 21 needs to be sufficiently high so that the honeycomb core is not easily displaced when placed on the conveyor belt 21. This setting can ensure that the honeycomb core panel 6 is not easily deformed during cutting. For example, the conveyor belt 21 can be made of a felt material with a certain degree of air permeability.

[0106] An exemplary usage process of the aforementioned honeycomb core panel cutting equipment is as follows:

[0107] The honeycomb core board 6 to be cut is placed at the front end of the conveyor belt 21. When it is transported to the processing station by the conveyor belt 21, the negative pressure generator is turned on and the hollow support surface of the corresponding area is controlled to generate negative pressure, so that the honeycomb core board 6 is adsorbed and attached to the conveyor belt 21. The moving bracket 31 and the vibration drive module 32 are controlled to move to perform the cutting work of the preset contour.

[0108] For example, the cutting device is started, causing the sheet-like blade to vibrate up and down; first, the moving bracket 31 moves along the length of the honeycomb core board support platform 5, and the cutting mechanism cuts one long side of the honeycomb core board 6; then the cutting mechanism moves along the guide rail on the moving bracket 31 and cuts one wide side of the honeycomb core board 6; next, the moving bracket 31 returns to its original position along the length of the honeycomb core board support platform 5, and the cutting mechanism cuts another long side of the honeycomb core board 6; finally, the cutting mechanism returns to its original position along the guide rail on the moving bracket 31 and cuts another wide side of the honeycomb core board 6, thus completing the cutting of a rectangular trajectory.

[0109] After cutting, the negative pressure generator is turned off, and the honeycomb core board 6 is sent out via conveyor belt 21. The products and scraps are sorted out, the table is cleaned, and the next honeycomb core board 6 is prepared for processing.

[0110] It should be understood that although quantifiers such as "first," "second," etc., may be used herein to describe various units, these units should not be limited by these terms.
