Description

Technical Field

[0001] This utility model relates to the field of aerogel die-cutting technology, and in particular to an aerogel clamping and fixing device for a die-cutting table. Background Technology

[0002] In the processing of aerogel materials, die-cutting is a key step, requiring precise cutting of the aerogel to obtain a specific shape.

[0003] Because aerogel is lightweight, has a loose structure, and is easily deformed, traditional mechanical clamps or manual pressing can easily cause material damage and wrinkles due to excessive local pressure, affecting cutting accuracy. Negative pressure fixing is usually used to fix it, which generates a uniform adsorption force through air pressure difference, allowing the aerogel to adhere flatly to the work surface and avoid damage caused by mechanical contact.

[0004] However, considering that placing the aerogel on the cutting platform requires shutting down the negative pressure system, adjusting the aerogel's position, and then restarting the negative pressure system to fix the aerogel, the operation process is not only cumbersome, requiring manual intervention to shut down and restart the negative pressure system, adding extra steps, extending the preparation time for each processing cycle, and reducing overall processing efficiency, but also that repeated starting and stopping of the negative pressure system can easily cause equipment wear and tear. Frequent pressure fluctuations can accelerate the aging of core components such as the negative pressure pump, shortening the equipment's service life. Therefore, an aerogel clamping and fixing device for the die-cutting table is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an aerogel clamping and fixing device for a die-cutting table. It aims to solve the problem that in the existing technology, the negative pressure fixing process requires turning off the negative pressure system to adjust the position and then restarting the system to fix the aerogel. This is not only cumbersome to operate, requiring manual intervention to start and stop the negative pressure system, adding extra steps, extending the preparation time for each processing, and reducing overall efficiency, but also causes core components such as the negative pressure pump to age faster due to frequent pressure fluctuations due to repeated start and stop, thus shortening the service life of the equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an aerogel clamping and fixing device for a die-cutting table, comprising a base, a top plate fixedly connected to the top of the outer surface of the base by bolts, a negative pressure hole opened at the top of the outer surface of the top plate, a sealing plate slidably connected to the top of the inner surface of the base, the inner surface of the sealing plate being elastically connected to the top of the inner surface of the base by spring B, the top of the outer surface of the sealing plate being inserted into the bottom of the outer surface of the top plate, a sealing element fixedly connected to the bottom of the outer surface of the top plate, a sealing groove opened on the outer surface of the sealing plate, the outer surface of the sealing element being inserted into the inner surface of the sealing groove, and a die-cutting assembly provided on the top of the outer surface of the top plate; The die-cutting assembly includes a telescopic motor, a support frame is fixedly connected to the top of the outer surface of the top plate, the outer surface of the telescopic motor is fixedly connected to the top of the outer surface of the support frame, the output shaft of the telescopic motor is fixedly connected to a cutting mold, and the bottom of the outer surface of the cutting mold is in contact with the top of the outer surface of the top plate.

[0007] As a further description of the above technical solution: The outer surface of the cutting mold is elastically connected to a lower pressure plate via spring A, and the outer surface of the sealing plate is fixedly connected to an action plate. The bottom end of the outer surface of the lower pressure plate is in contact with the top end of the outer surface of the action plate.

[0008] As a further description of the above technical solution: A guide post is fixedly connected to the top of the inner surface of the base, and the outer surface of the guide post penetrates and is slidably connected to the inner surface of the sealing plate.

[0009] As a further description of the above technical solution: One end of the spring B is fixedly connected to the top of the inner surface of the base, and the other end of the spring B is fixedly connected to the bottom of the outer surface of the sealing plate.

[0010] As a further description of the above technical solution: One end of the spring A is fixedly connected to the outer surface of the cutting mold, and the other end of the spring A is fixedly connected to the top of the outer surface of the lower pressure plate.

[0011] As a further description of the above technical solution: An air intake pipe is fixedly connected to the front end of the outer surface of the base.

[0012] As a further description of the above technical solution: Ventilation slots are provided on both the left and right sides of the outer surface of the base.

[0013] As a further description of the above technical solution: Both the pressure plate and the action plate are provided in two sets, and are arranged symmetrically.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the sealing plate and spring B work together to automatically switch between blocking and exposing the negative pressure hole. When not cutting, the sealing plate blocks the negative pressure hole under the elastic force of spring B, which facilitates free adjustment of the aerogel position. When cutting, the sealing plate is driven to move down by external force to open the negative pressure channel. There is no need to manually intervene in the start and stop of the negative pressure system throughout the process, which reduces the number of operation steps and avoids the impact of frequent start and stop on the equipment life, significantly improving the continuity and efficiency of processing.

[0015] 2. In this utility model, when the cutting mold moves down, the spring A drives the lower pressure plate to contact the action plate first, triggering the sealing plate to move down and open the negative pressure adsorption. The elastic characteristics of the spring A not only ensure that the negative pressure is activated in time before cutting, but also continuously apply pressure to the action plate to maintain the stability of the negative pressure when the cutting mold continues to move down to complete the cutting action. This realizes the continuous linkage between fixing and cutting, and improves the degree of automation and processing accuracy. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3This utility model provides an embodiment of an aerogel clamping and fixing device for a die-cutting table, comprising a base 1, with a top plate 2 fixedly connected to the top of the outer surface of the base 1 by bolts. The bolted connection ensures the stability of the connection between the base 1 and the top plate 2, preventing loosening during device operation. Simultaneously, the bolted connection facilitates later disassembly, maintenance, component replacement, or structural adjustment of the device. A negative pressure hole 8 is provided at the top of the outer surface of the top plate 2. The negative pressure hole 8 is a key channel for achieving negative pressure adsorption of the aerogel, transmitting the negative pressure environment between the base 1 and the top plate 2 to the bottom of the aerogel, thereby generating adsorption force. A sealing plate 11 is slidably connected to the top of the inner surface of the base 1. The sliding connection design of the sealing plate 11 allows it to change its position according to the force, thereby blocking or exposing the negative pressure hole 8, thus controlling the opening and closing of the negative pressure adsorption. The inner surface of the sealing plate 11 is elastically connected to the top of the inner surface of the base 1 through a spring B12. The elastic connection of the spring B12 provides the reset force for the sealing plate 11. When the sealing plate 11 is not under downward pressure, it can move upward under the elastic force of the spring B12, restore the initial position to block the negative pressure hole 8, and ensure that the negative pressure adsorption is in the closed state when not in operation.

[0020] Reference Figures 2-4 The top of the outer surface of the sealing plate 11 is inserted into the bottom of the outer surface of the top plate 2. The insertion of the two enhances the sealing of the contact surface, reduces the leakage of negative pressure during transmission, and ensures that sufficient adsorption force can be generated when the negative pressure is adsorbed. A sealing element 15 is fixedly connected to the bottom of the outer surface of the top plate 2. The sealing element 15 can fill the gap between the top plate 2 and the sealing plate 11, further improving the sealing performance of the contact part and preventing the negative pressure from being lost from the gap. A sealing groove 14 is opened on the outer surface of the sealing plate 11. The sealing groove 14 cooperates with the sealing element 15. When the two are inserted, they can form a good sealing structure, blocking the transmission path of negative pressure. When separated, the transmission path is opened, realizing precise control of the negative pressure on and off. The outer surface of the sealing element 15 is inserted into the inner surface of the sealing groove 14. This insertion structure can effectively prevent the negative pressure from passing through when sealed, ensuring the stability of the non-adsorption state. When separated, it allows the negative pressure to be transmitted smoothly, ensuring the normal realization of the adsorption function.

[0021] Reference Figures 1-2The top surface of the top plate 2 is equipped with a die-cutting assembly 4. The die-cutting assembly 4 is the core execution component of the device to realize the aerogel cutting function, providing the necessary structural and power support for the cutting operation. The die-cutting assembly 4 includes a telescopic motor 401. A support frame 3 is fixedly connected to the top surface of the top plate 2. The support frame 3 provides a stable installation base for the telescopic motor 401, which can withstand the vibration and force generated by the telescopic motor 401 during operation, ensuring its stable operation. The outer surface of the telescopic motor 401 is fixedly connected to the top surface of the support frame 3 to prevent displacement or shaking during operation, thereby ensuring the movement accuracy of the cutting mold 402. The output shaft of the telescopic motor 401 is fixedly connected to the cutting mold 402, so that the cutting mold 402 can move up and down accurately with the output shaft to complete the cutting action. The bottom end of the outer surface of the cutting mold 402 is in contact with the top end of the outer surface of the top plate 2 to ensure the thoroughness and accuracy of the cutting, and to avoid problems such as incomplete cutting or positional deviation.

[0022] Reference Figures 1-2 The outer surface of the cutting mold 402 is elastically connected to the lower pressure plate 5 via spring A6. When the cutting mold 402 is cutting, the lower pressure plate 5 contacts the action plate 7 before cutting, moving the sealing plate 11 downward and fixing the aerogel with negative pressure through the negative pressure hole 8 before cutting. Due to the elasticity of spring A6, the cutting mold 402 can continue to move the lower pressure plate 5 to the designated position while cutting. However, the elastic force of spring A6 can still continuously press down on the action plate 7. The action plate 7 is fixedly connected to the outer surface of the sealing plate 11. As a force transmission medium, the action plate 7 can effectively transmit the pressure applied by the lower pressure plate 5 to the sealing plate 11, thereby driving the sealing plate 11 to move accordingly. The bottom end of the outer surface of the lower pressure plate 5 is in contact with the top end of the outer surface of the action plate 7. This contact connection method can ensure that the pressure of the lower pressure plate 5 is smoothly transmitted to the action plate 7, thereby driving the sealing plate 11 to move and realize the opening control of negative pressure adsorption.

[0023] Reference Figure 2 A guide post 13 is fixedly connected to the top of the inner surface of the base 1. The guide post 13 provides a precise guide trajectory for the up and down movement of the sealing plate 11, preventing the sealing plate 11 from shifting or tilting during the movement. The outer surface of the guide post 13 penetrates and slides through the inner surface of the sealing plate 11, ensuring the sealing fit accuracy between the sealing plate 11 and the top plate 2, and avoiding the negative pressure effect due to the offset of the sealing plate 11.

[0024] Reference Figures 1-2One end of spring B12 is fixedly connected to the top of the inner surface of base 1, and the other end of spring B12 is fixedly connected to the bottom of the outer surface of sealing plate 11, so that spring B12 can stably apply an upward elastic force to sealing plate 11. When the downward pressure on sealing plate 11 disappears, it can push sealing plate 11 to quickly reset and restore the blocking state of negative pressure hole 8. One end of spring A6 is fixedly connected to the outer surface of cutting mold 402, and the other end of spring A6 is fixedly connected to the top of the outer surface of lower pressure plate 5. The fixed connection of both ends of spring A6 can ensure that it moves synchronously with cutting mold 402, and at the same time provide continuous and stable pre-pressure to lower pressure plate 5, ensuring the pre-pressure effect of lower pressure plate 5 on aerogel.

[0025] Reference Figures 1-2 The outer surface of the base 1 is fixedly connected to the front end of the suction pipe 9. The suction pipe 9 is a channel connecting the negative pressure pump and the inside of the device. It can introduce the negative pressure generated by the negative pressure pump into the interlayer between the base 1 and the top plate 2 to provide a power source for negative pressure adsorption. Ventilation slots 10 are provided on the left and right sides of the outer surface of the base 1. The ventilation slots 10 can balance the air pressure inside the base 1 and the outside, so as to avoid the negative pressure pump's suction efficiency being affected by the low air pressure inside the base 1, and ensure the smoothness of the negative pressure extraction process. The lower pressure plate 5 and the action plate 7 are provided in two sets and are symmetrically arranged. The symmetrical arrangement can make the pressure on the sealing plate 11 evenly distributed, avoid the sealing plate 11 tilting due to uneven force, ensure the stability of the movement of the sealing plate 11, and improve the overall operational stability of the device.

[0026] Working principle: When cutting the aerogel, first start the negative pressure pump connected to the suction pipe 9 to continuously extract the air from the gap between the top of the base 1 and the top plate 2. Then, place the aerogel on the surface of the top plate 2. At this time, the bottom of the negative pressure hole 8 on the top plate 2 will be blocked by the sealing plate 11, preventing the aerogel from being fixed by negative pressure. The position of the aerogel can be adjusted at will. When the position of the aerogel is adjusted, start the telescopic motor 401 to move the cutting mold 402 downward. At the same time, it will move the lower pressure plate 5 downward through the spring A6. When the bottom of the lower pressure plate 5 contacts the top of the action plate 7 on the sealing plate 11, the sealing plate 11 will be moved downward as well, thereby releasing the sealing plate 11 from the bottom of the negative pressure hole 8. The sealing plate 11 blocks the ventilation slot 10, allowing the negative pressure to be applied only through the sealing groove 14 on the sealing plate 11 to fix the bottom of the aerogel with negative pressure. This prevents the aerogel from shifting when the cutting mold 402 cuts it. When the cutting mold 402 moves upward, the lower pressure plate 5 stops pressing the top of the action plate 7 on the sealing plate 11, allowing the sealing plate 11 to reset upward under the elastic force of the spring B12, reconnecting with the bottom of the top plate 2 and blocking the bottom of the negative pressure hole 8, thus facilitating the removal of the cut aerogel from the top plate 2.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
