Description

Technical Field

[0001] This utility model relates to the field of bubble elimination devices, specifically a bubble elimination device for epoxy resin processing. Background Technology

[0002] When potting epoxy resin, a curing agent is usually used to cure it. When epoxy resin and curing agent are mixed, a lot of air bubbles are generated. When these air bubbles fill the cured epoxy resin, they will cause a decrease in the tensile strength, compressive strength, hardness, heat resistance and chemical corrosion resistance of the epoxy resin. When air bubbles appear on the surface of the cured epoxy resin, they will affect the surface smoothness of the epoxy resin.

[0003] Therefore, a bubble elimination device for epoxy resin processing is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: An epoxy resin processing bubble elimination device of this utility model includes a base, a tank on the top of the base, a cover plate on the top of the tank, a power component for controlling the lifting and lowering of the cover plate on the top of the base, a motor fixedly connected to the top of the cover plate, a rotating shaft fixedly connected to the output end of the motor, the rotating shaft and the cover plate being through-connected and rotatably connected, multiple stirring frames fixedly connected to the middle of the rotating shaft, multiple stirring blades fixedly connected to the inner wall of the stirring frames, the stirring blades being inclined and having multiple openings symmetrically formed on their surfaces, the openings having sharp corners; through the combined action of the stirring blades and the openings, the epoxy resin in the tank is continuously stirred by the stirring blades to uniformly discharge and break up the internal bubbles, thereby improving the device's effect on eliminating bubbles in epoxy resin.

[0006] Preferably, multiple ultrasonic transducers are fixed to the outer wall of the tank; the ultrasonic transducers are arranged in a circumferential array; by setting ultrasonic transducers, the epoxy resin inside the tank will be subjected to additional ultrasonic waves during stirring, which accelerates the elimination rate of internal bubbles and improves the effect of the device on eliminating bubbles in the epoxy resin.

[0007] Preferably, one side of the tank is connected to an air extraction port; the other side of the tank is connected to an air inlet. After the material inside the tank is added, it is sealed with a cover plate. Then, the valve of one side air extraction port can be opened and connected to a vacuum pump to put the inside of the tank under negative pressure. Under negative pressure, the escape of bubbles can be accelerated, especially the bubbles on the surface of epoxy resin are more likely to expand and burst. This can reduce the number of bubbles remaining on the surface of epoxy resin after curing, and also reduce the number of bubbles on the surface of epoxy resin that fail to burst quickly and are brought into the epoxy resin during stirring. After stirring, the tank can be pressurized by filling it with air through the air inlet on the other side to restore it to normal pressure. It is worth mentioning that the tank and cover plate can be made of steel and should have a certain compressive strength, such as the container should not deform when the negative pressure inside the container is ≤-0.5Mp.

[0008] Preferably, a sealing bearing is installed on the top of the cover plate; the sealing bearing and the rotating shaft are in a mating relationship; by setting the sealing bearing, the sealing bearing can seal the connection between the rotating shaft and the tank, reducing leakage when the device draws air from the inside of the tank through the air extraction port, and improving the airtightness of the device during operation.

[0009] Preferably, the power assembly includes a hydraulic cylinder; the hydraulic cylinder and the base are fixedly connected; ear plates are symmetrically fixedly connected to both sides of the cover plate; one ear plate is fixedly connected to the output end of the hydraulic cylinder; a telescopic rod is fixedly connected to the bottom of the other ear plate; the telescopic rod and the base are also fixedly connected; by setting the hydraulic cylinder, when the cover plate needs to be opened or closed, the cover plate and ear plates can be raised and lowered by activating the hydraulic cylinder, and the telescopic rod will provide additional guiding and supporting functions to ensure that the cover plate can move stably and improve the convenience of the device for adding and removing materials from the tank.

[0010] Preferably, a gasket is fixed to the inner wall of the cover plate; the surface of the gasket has an arc-shaped structure; by setting the gasket, the gasket will seal the connection between the tank and the cover plate when the tank and the cover plate are connected, and the gasket can be made of rubber or nylon.

[0021] 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 scope of protection of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figures 1 to 5As shown in the embodiment of this utility model, an epoxy resin processing bubble elimination device includes a base 1, a tank 12 on the top of the base 1, a cover plate 13 on the top of the tank 12, a power assembly for controlling the lifting and lowering of the cover plate 13 on the top of the base 1, a motor 14 fixedly connected to the top of the cover plate 13, a rotating shaft 15 fixedly connected to the output end of the motor 14, the rotating shaft 15 and the cover plate 13 being through-connected and rotatably connected, a plurality of stirring racks 16 fixedly connected to the middle of the rotating shaft 15, a plurality of stirring blades 17 fixedly connected to the inner wall of the stirring racks 16, the stirring blades 17 being inclined and having a plurality of openings 18 symmetrically opened on their surfaces, the corners of the openings 18 being sharp; during operation, the lifting of the cover plate 13 can be controlled by the power assembly, and after material is added into the tank 12, the cover plate 13 can be driven to lower. The tank 12 is then sealed. The motor 14 is then activated, causing the rotating shaft 15 to drive multiple stirring racks 16 to rotate. As the stirring racks 16 rotate, they work in conjunction with the stirring blades 17. Because the stirring blades 17 are angled, they push the epoxy resin from the bottom and middle of the tank 12 to the surface, accelerating the diffusion of air bubbles to the surface and their removal. Furthermore, because the multiple stirring blades 17 are at different distances from the rotating shaft 15, the stirring areas complement each other, resulting in more uniform stirring. Simultaneously, the sharp opening 18 effectively breaks up air bubbles encountered during stirring. Through the combined action of the stirring blades 17 and the opening 18, the epoxy resin inside the tank 12 is continuously stirred by the stirring blades 17 to evenly remove and break up internal air bubbles, improving the device's effectiveness in eliminating air bubbles from the epoxy resin.

[0024] Please see Figure 2 As shown, multiple ultrasonic transducers 2 are fixed to the outer wall of the tank 12; the ultrasonic transducers 2 are arranged in a circumferential array; by setting the ultrasonic transducers 2, the ultrasonic waves emitted after the ultrasonic transducers 2 are energized can eliminate air bubbles inside the epoxy resin in the container, thereby improving the device's effect on removing air bubbles from the epoxy resin. At the same time, due to the centrifugal effect when the rotating shaft 15 rotates, the stirring blades 17 can continuously push the epoxy resin in the middle part of the tank 12 towards the outer part where ultrasonic bubble elimination is most effective. By setting the ultrasonic transducers 2, the epoxy resin in the tank 12 will be subjected to additional ultrasonic waves during stirring, which accelerates the elimination rate of air bubbles inside the resin and also improves the device's effect on eliminating air bubbles from the epoxy resin.

[0025] Please see Figure 1 and Figure 2As shown, one side of the tank 12 is connected to an air extraction port 3; the other side of the tank 12 is connected to an air inlet 32. After the material inside the tank 12 is added, it is sealed by the cover plate 13. Then, the valve of the air extraction port 3 on one side can be opened and connected to a vacuum pump to make the inside of the tank 12 under negative pressure. Under negative pressure, the escape of bubbles can be accelerated, especially the bubbles on the surface of epoxy resin are more likely to expand and burst, thereby reducing the residual bubbles on the surface of epoxy resin after curing, and also reducing the risk of bubbles on the surface of epoxy resin failing to burst quickly and being carried into the epoxy resin during stirring. After stirring, the tank 12 can be pressurized by filling it with air through the air inlet 32 ​​on the other side to restore it to normal pressure. It is worth mentioning that the tank 12 and the cover plate 13 can be made of steel and should have a certain compressive strength, such as the container not deforming when the negative pressure inside the container is ≤-0.5Mp.

[0026] Please see Figure 4 As shown, a sealing bearing 4 is installed on the top of the cover plate 13; the sealing bearing 4 and the rotating shaft 15 are in a mating relationship; by setting the sealing bearing 4, the sealing bearing 4 can seal the connection between the rotating shaft 15 and the tank body 12, reduce the leakage that occurs when the device draws air from the inside of the tank body 12 through the air extraction port 3, and improve the airtightness of the device during operation.

[0027] Please see Figure 2 and Figure 3 As shown, the power assembly includes a hydraulic cylinder 5; the hydraulic cylinder 5 and the base 1 are fixedly connected; ear plates 52 are symmetrically fixedly connected to both sides of the cover plate 13; one ear plate 52 is fixedly connected to the output end of the hydraulic cylinder 5; a telescopic rod 53 is fixedly connected to the bottom of the other ear plate 52; the telescopic rod 53 and the base 1 are also fixedly connected; by setting the hydraulic cylinder 5, when the cover plate 13 needs to be opened or closed, the cover plate 13 and the ear plates 52 can be driven to rise and fall by activating the hydraulic cylinder 5, and the telescopic rod 53 will provide additional guiding and supporting functions to ensure that the cover plate 13 can move stably and improve the convenience of the device for adding and removing materials from the tank 12.

[0028] Please see Figure 3 As shown, a gasket 6 is fixed to the inner wall of the cover plate 13; the surface of the gasket 6 is an arc-shaped structure; by setting the gasket 6, when the tank body 12 and the cover plate 13 are connected, the gasket 6 will seal the connection between the tank body 12 and the cover plate 13. The gasket 6 can be made of rubber or nylon.

[0029] Working principle: The power unit controls the lifting of the cover plate 13. After material is added into the tank 12, the cover plate 13 is driven to descend to seal the tank 12. Then, the motor 14 is started, causing the rotating shaft 15 to drive multiple stirring racks 16 to rotate. When the stirring racks 16 rotate, they will rotate together with the stirring blades 17. Because the stirring blades 17 are inclined, they can push the epoxy resin at the bottom and middle of the tank 12 to the surface when rotating, thereby accelerating the diffusion of air bubbles to the surface and their elimination. In addition, because the multiple sets of stirring blades 17 are at different distances from the rotating shaft 15, they form complementary stirring parts, which can make the stirring more uniform. The opening 18 is designed with a sharp point to better break up air bubbles encountered during stirring. An ultrasonic transducer 2, when energized, emits ultrasonic waves to eliminate air bubbles inside the epoxy resin in the container, improving the device's ability to remove air bubbles. Simultaneously, due to the centrifugal force of the rotating shaft 15, the rotating impeller 17 continuously pushes the epoxy resin in the middle of the tank 12 towards the outermost area where ultrasonic bubble elimination is most effective. After the material inside the tank 12 is fully added, it is sealed by the cover plate 13. Then, by opening the valve of one side's exhaust port 3 and connecting it to a vacuum pump, the inside of the tank 12 is kept in a vacuum. Under negative pressure, the escape of bubbles is accelerated, especially bubbles on the surface of epoxy resin, which expand and burst more easily. This reduces the amount of residual bubbles on the surface of the cured epoxy resin and also reduces the risk of bubbles failing to burst quickly and being introduced into the epoxy resin during stirring. After stirring, the tank 12 can be pressurized through the air inlet 32 ​​on the other side to restore it to normal pressure. It is worth mentioning that the tank 12 and the cover plate 13 can be made of steel and should have a certain compressive strength, such as not deforming the container when the negative pressure inside the container is ≤-0.5Mp. By setting a sealed bearing 4, the sealed bearing 4 can support the rotating shaft 15. The connection between the cover plate 12 and the tank body 12 is sealed to reduce leakage when the device evacuates air from the tank body 12 through the evacuation port 3, thereby improving the airtightness of the device during operation. By setting up the hydraulic cylinder 5, when it is necessary to open or close the cover plate 13, the cover plate 13 and the ear plate 52 can be raised and lowered by activating the hydraulic cylinder 5. The telescopic rod 53 will provide additional guidance and support to ensure that the cover plate 13 can move stably, thereby improving the convenience of the device for adding and removing materials from the tank body 12. By setting up the gasket 6, when the tank body 12 and the cover plate 13 are connected, the gasket 6 will seal the connection between the tank body 12 and the cover plate 13. The gasket 6 can be made of rubber or nylon.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
