Description

Technical Field

[0001] This utility model relates to the field of soluble substance detection in plastic products, and more specifically, to an extraction device for soluble substance detection in plastic products. Background Technology

[0002] The detection of soluble substances in plastic products involves simulating actual usage conditions and using specific solvents (such as water, alcohols, or simulated solutions) to extract chemical substances from plastics under controlled temperature, time, and liquid-solid ratio conditions. This is combined with analytical techniques such as chromatography and spectroscopy to quantitatively detect potentially harmful substances such as migrated additives, residual monomers, degradation products, and heavy metals. The aim is to assess the safety of these substances to human health and the environment, ensure compliance with domestic and international regulations, and provide crucial data support for material research and development, production quality control, and product compliance. To extract soluble substances, an extraction device specifically designed for the detection of soluble substances in plastic products is required.

[0003] A search revealed that Chinese patent CN221889220U discloses an "Intelligent Extraction Device for Soluble Content in Asphalt Waterproofing Membranes," which includes a test bench. The test bench is equipped with an extraction device, a sample placement device, a condenser placement device, and a four-axis robot. The extraction device, sample placement device, and condenser placement device are distributed around the four-axis robot, and the robot's drive end can move above these devices. The extraction device includes an automatic heating jacket, a round-bottom flask, a solenoid extraction tube, a condenser, and a mesh bag. The bottom of the round-bottom flask is fitted onto the output end of the automatic heating jacket. This extraction device not only reduces the operation time required for solution addition, waste liquid recovery, condenser clamping and placement, and sample clamping and placement, thus improving the efficiency of the extraction process and the efficiency of asphalt waterproofing membrane soluble content testing, but also reduces environmental pollution and protects the health and safety of operators. However, it still has the following drawbacks: (1) Most of the plastic product soluble extractor detection and extraction devices on the market are not very quick to use. They do not provide the structure with the effect of quickly separating soluble and insoluble substances, which reduces the working speed of subsequent work, affects the overall work process, reduces the overall work efficiency, and is not conducive to the rapid use of plastic product soluble extractor detection and extraction devices.

[0004] The existing methods do not provide a quick way to remove soluble substances from the structure, requiring manual removal by staff. This reduces the overall workflow, increases the workload for staff, and hinders the rapid completion of the task. Therefore, an extraction device for detecting soluble substances in plastic products is proposed. Utility Model Content

[0020] 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.

[0021] As shown in 1-5, this embodiment proposes an extraction device for detecting soluble substances in plastic products, including a support plate 1. A positioning motor 2 is fixedly connected to one side of the support plate 1. The output shaft of the positioning motor 2 is fixedly connected to a transmission gear 3 via a coupling. A toothed block 4 meshes with the outer wall of the transmission gear 3. A connecting frame plate 5 is fixedly connected to one side of the toothed block 4. A side connecting block 6 is fixedly connected to one side of the connecting frame plate 5. A long plate 7 is fixedly connected to one side of the side connecting block 6. A stirring motor 8 is fixedly connected to the top of the long plate 7. A stirring column 9 is fixedly connected to the output shaft of the stirring motor 8 via a coupling.

[0022] A stirring blade 10 is fixedly connected to the outer wall of the stirring column 9. A bearing 11 is fixedly connected to the outer wall of the stirring column 9. An inner plate 12 is fixedly connected to the outer wall of the bearing 11. An outer rubber ring 13 is fixedly connected to the outer wall of the inner plate 12. A heating tube column 14 is fixedly connected inside the stirring column 9. An extraction circular frame 15 is movably connected to the outer wall of the outer rubber ring 13. This makes the extraction device for detecting and extracting soluble substances in plastic products easier to use. It can provide a rapid separation effect between soluble and insoluble substances in the structure, speed up the subsequent work, and improve the overall work efficiency. This is conducive to the rapid use of the extraction device for detecting and extracting soluble substances in plastic products.

[0023] As shown in 1-5, in a preferred embodiment, based on the above method, a side connecting plate 16 is fixedly connected to the outer wall of the extraction circular frame 15, and a side motor 17 is fixedly connected to one side of the side connecting plate 16, which allows the direction of the extraction circular frame 15 to be adjusted, so that the internal material can be quickly obtained. A short plate 18 is fixedly connected to one side of the side motor 17, and the height of the short plate 18 is less than the height of the extraction circular frame 15, providing support for the connection structure. A base plate 19 is fixedly connected to the bottom of the short plate 18, and the length and width of the base plate 19 are both greater than the diameter of the extraction circular frame 15, providing support for the overall structure.

[0024] The coupling of the adjusting motor 2 passes through the support plate 1 and is fixedly connected to one side of the transmission gear 3. There are two adjusting motors 2 and two transmission gears 3, which allows the connecting frame plate 5 to rise stably. The outer wall of the inner plate 12 is fixedly connected to the inner wall of the outer rubber ring 13. The top of the inner plate 12 is provided with a leakage hole to prevent the inside of the extraction frame 15 from sticking when separating insoluble substances. It also facilitates the flow of liquid into the bottom of the inner plate 12 when it rises. The inside of the stirring column 9 is fixedly connected to the bottom of the heating tube column 14. The height of the heating tube column 14 is less than the height of the stirring column 9, which facilitates the control of the working temperature inside the extraction frame 15.

[0025] Specifically, in use, the extraction device for detecting soluble substances in plastic products involves placing all the required test material and solvent into the extraction frame 15. The heating column 14 heats the material to the appropriate test temperature. Simultaneously, the stirring motor 8 operates, and its output shaft rotates, causing the stirring column 9 to drive the stirring blades 10, thus ensuring uniform mixing of the internal materials. Due to the bearing 11, the inner plate 12 does not rotate within the extraction frame 15. After the leaching test is completed, the adjustment motor 2 starts operating. The rotation of the output shaft of the motor 2 causes the transmission gear 3 to rotate. The rotation of the transmission gear 3 causes the tooth block 4 to move the connecting frame plate 5 upward, thereby moving the stirring column 9 and the inner plate 12 upward. This allows the inner plate 12 to carry out the insoluble matter inside, thus completing the rapid separation of insoluble and soluble matter. Afterward, the side motor 17 works, and the rotation of the output shaft of the side motor 17 causes the side connecting plate 16 to drive the extraction frame 15 to rotate, thereby tilting the extraction frame 15 and causing the solvent and soluble matter inside to be quickly poured out.

[0026] All technical features in this embodiment can be freely combined according to actual needs.

[0027] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
