Description

Technical Field

[0001] This utility model belongs to the field of resin treatment technology, specifically referring to a resin vacuum defoaming machine. Background Technology

[0002] Resin generally refers to an organic polymer that softens or melts when heated, tends to flow under external force when softened, and is solid, semi-solid, or sometimes liquid at room temperature. In a broad sense, any polymer compound that can be used as a raw material for processing plastic products is called resin. During the resin processing, it is usually necessary to defoam the resin.

[0003] Traditional methods for eliminating bubbles generated during resin solution mixing and stirring include hot water baths, hot air blowing, and the use of industrial vacuum pumps. However, these methods are not only inefficient but also pose certain safety risks. Existing equipment for creating a vacuum environment is often industrial in nature, requiring a large footprint and specific material requirements for containers, making it difficult to meet users' actual needs. Current defoaming machines require users to manually close the air inlet rubber plug before vacuuming, which is not only extremely inconvenient and prone to omissions, but also causes resin to splash out of the container during venting, negatively impacting the user experience. Utility Model Content

[0004] To solve the above problems, this utility model provides a resin vacuum defoaming machine.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: a resin vacuum defoaming machine, including a chamber and a top cover, wherein the chamber and the top cover are detachably connected, the top of the top cover is provided with a function key, the top cover is provided with a portable pressure relief valve and a power interface, and a diaphragm vacuum pump is provided inside the top cover.

[0006] As a preferred embodiment of this utility model, a silicone pad is fitted at the bottom of the cabin, and the bottom of the silicone pad is uniformly provided with hollowed-out round holes.

[0007] As a preferred technical solution of this utility model, the upper cover is made of ABS material and the cabin is made of PC material.

[0008] Compared with existing technologies, the present invention achieves the following beneficial effects by adopting the above structure: The unique hand-held pressure relief valve design allows for pressure relief by simply lifting the handle upwards. After pressure relief, the valve automatically returns to its original position. This design avoids the need to manually close the valve before vacuuming, ensuring successful vacuuming and improving user experience. Simultaneously, the pressure relief valve design allows for slow pressure release, preventing resin solution splashing due to excessively rapid pressure relief. Gas is injected into the chamber, maintaining a high-pressure working environment within the chamber. The principle of airflow degassing is used to purify the liquid. When the airflow contacts the liquid, it creates negative pressure on the air bubbles, forcing them out and separating, thus purifying the liquid. Users only need to activate degassing with a single button by lifting the pressure relief valve. After pressure relief, there is no need to manually close the valve. The maximum negative pressure value is -95 kPa, effectively eliminating air bubbles in the resin solution, significantly improving the quality and clarity of resin crafts. The overall design is lightweight and easy to carry, while also meeting strength requirements during use. Attached Figure Description

[0013] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0014] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.

[0015] like Figure 1-3 As shown, this utility model provides a resin vacuum defoamer, including a chamber 1 and a top cover 2. The top cover 2 is made of ABS material, and the chamber 1 is made of PC material. The overall design is lightweight, portable, and easy to use, while meeting strength requirements during use. The chamber 1 and the top cover 2 are detachably connected and held together by negative pressure. A function key 3 is located on the top of the top cover 2, which also features a portable pressure relief valve 4 and a power interface 5. The unique portable pressure relief valve 4 design allows for pressure relief by simply lifting the handle upwards. After pressure relief, the valve automatically returns to its original position, avoiding the need to manually close the valve before vacuuming. This ensures successful vacuuming and improves user experience. At the same time, the pressure relief valve is designed to release pressure slowly, avoiding excessive pressure release that could cause resin solution to splash. Gas is injected into the chamber 1, and the airflow degassing principle is used to purify the liquid. When the airflow comes into contact with the liquid, it creates negative pressure on the bubbles in the liquid, forcing the bubbles to be squeezed out and separated, thus purifying the liquid. A diaphragm vacuum pump 6 is installed inside the top cover 2. The diaphragm vacuum pump 6 can reach the maximum negative pressure value in about 105 seconds when the equipment container is unloaded. A silicone pad 7 is fitted on the bottom of the chamber 1, and the bottom of the silicone pad 7 is evenly provided with perforated round holes.

[0016] In practical use, the power interface 5 uses a Type-C connector. Press the function button to turn it on, and press it again to pause. The default working time is 10 minutes, which can meet the effective defoaming requirements of processing 10 ounces of resin solution each time. At the same time, users can extend the working time according to the characteristics and quality of the resin. Simply lift the portable pressure relief valve 4 to complete the pressure relief operation. After the pressure relief is completed, the pressure relief valve will automatically return to its original position. The diaphragm vacuum pump 6 can reach the maximum negative pressure value in about 105 seconds when the equipment container is unloaded.

[0017] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
