Description

Technical Field

[0001] The invention specifically relates to the technical field of chemical raw material detection, and in particular to a chemical raw material detection device. Background Art

[0002] At present, there are five common methods for detecting chemical raw materials, namely high performance liquid chromatography (HPLC), ultraviolet absorption spectrometry (UV), thin layer chromatography (TLC), gas chromatography (GC) and atomic absorption spectrometry (AAS).

[0003] Each method has different working principles and applications; among them, HPLC and UV are commonly used detection methods for standard plant extracts, TLC is used for the detection of proportional plant extracts, GC is used to detect volatile liquids or oils, and AAS is used to detect the heavy metal content of extracts.

[0004] Among them, thin layer chromatography is a very important experimental technique for rapid separation and qualitative analysis of small amounts of substances. It combines the advantages of column chromatography and paper chromatography. On the one hand, it is suitable for the separation of small amounts of samples; on the other hand, when making thin layer plates, the adsorption layer is thickened and enlarged, so it can also be used to refine samples. This method is particularly suitable for raw materials with low volatility or that are prone to change at high temperatures and cannot be analyzed by gas chromatography.

[0005] However, when traditional chemical raw materials are tested by thin layer chromatography, they need to go through multiple steps. In this way, during the testing process, the slides cannot be automatically moved between each device. Therefore, they need to be placed in the device manually and wait for the process in the corresponding step to be completed. This will waste a lot of time for the staff and cannot effectively improve the testing efficiency of chemical raw materials.

[0006] The present invention is designed to provide a chemical raw material detection device. In the device, a sample solution tank and a developing agent tank are arranged in the same equipment frame body as a chromatographic analyzer. The electric push cylinder drives the slider to move, so that the fixed rod on the slider drives the flip head to move along the guide groove on the moving frame. In the process of moving up and down, the sleeve is fitted with the inner wall of the guide groove to realize a small swing of the moving frame. The rotating wheel on the moving frame drives the flip head to move the same distance while rotating. When the fixed rod moves to the arc section of the guide groove, the flip head realizes rotation by cooperating with the rotating wheel, and the fixed rod moves from In the process of moving one straight section of the guide groove to another straight section, the flip head realizes a 180° rotation by cooperating with the rotating wheel, and the paddle between the two carriers is adsorbed by the suction cup installed on the flip head. When the flip head moves downward, the carrier is driven to move downward by the paddle, so that the two loading racks can be rotated at the same time, and the adsorption position of the suction cup that moves the next paddle is realized. The T-plate is driven by the driving motor to move along the guide column, so that the glass slide passes through the sample solution tank and the developer tank in turn, and is finally placed in the placement tank, and the raw materials on the glass slide are detected by the chromatograph analyzer.

[0046] By adopting the above technical solution, when in use, the sample solution tank 6, the developing agent tank 7 and the placement tank 9 are placed in sequence, wherein the placement tank 9 is placed inside the chromatographic analyzer 4, so that the chromatographic analyzer 4 can effectively detect and analyze the raw materials on the glass slide;

[0047] Furthermore, during operation, a plurality of paddles are placed on the supporting columns 880 between the loading racks 88, and the suction cups 811 are driven to move by the flipping heads 810, so that the loading racks 88 can automatically rotate and load materials;

[0048] In this embodiment, a fixing rod 870 is fixedly installed on one side of the moving frame 89 away from the slider 87; a sleeve 871 is provided on the fixing rod 870; the fixing rod 870 passes through a guide slot 890 provided on the moving frame 89;

[0049] Specifically, the sleeve 871 is fitted with the inner wall of the guide groove 890; the top of the fixing rod 870 also passes through the through groove 8101 provided on the flip head 810 and is connected by a bearing; a sliding groove 8100 is also provided on the side where the flip head 810 is fitted with the moving frame 89, and the rotating wheel 892 provided on the moving frame 89 is located inside the sliding groove 8100;

[0050] By adopting the above technical scheme, when loading, the electric push cylinder 85 fixedly installed on one side of the bottom plate 84 drives the slide block 87 to move upward along the slide frame 86. In the process of the slide block 87 moving upward, the fixed rod 870 drives the flip head 810 to move. At this time, the sleeve 871 arranged on the fixed rod 870 moves along the inner wall of the guide groove 890 provided on the moving frame 89. When the sleeve 871 passes through the arc section of the guide groove 890 through the fixed rod 870, the moving frame 89 swings slightly through the rotating shaft 812. In the process of the swinging of the moving frame 89, the rotating wheel 892 installed on the moving frame 89 cooperates with the sliding groove 8100 provided on the flip head 810, so that the flip head 810 rotates along the rotating wheel 892, and the flip head 810 reverses 180°, and then moves upward through the straight section of the guide groove 890, so that the suction cup 811 contacts the glass slide on the loading frame 88, and the glass slide is loaded.

[0051] In this embodiment, the bottom of the flip head 810 is fixedly mounted on the suction cup 811; two symmetrical loading racks 88 are arranged above the flip head 810; a plurality of supporting columns 880 are arranged on the edge of the loading rack 88; a glass slide is placed between two adjacent supporting columns 880 in the two loading racks 88; the loading rack 88 is mounted in cooperation with the mounting shell 814 through a rotating shaft; the mounting shell 814 is fixedly mounted on the bottom plate 84 through a support rod;

[0052] The T-shaped plate 80 is also fixedly mounted with a spray pipe 10 and an air pipe 11 by means of buckles, wherein the spray pipe 10 is connected to the pump body 5; the air pipe 11 is connected to the negative pressure machine 2 fixedly mounted on the top of the frame body 1;

[0053] By adopting the above technical solution, after the loading is completed, the electric push cylinder 85 drives the slider 87 to move in the opposite direction, and the flip head 810 is reset through the cooperation with the moving frame 89, and the glass slide is moved to the working position. At this time, the pump body 5 is connected with the spray pipe 10 to realize the spraying of the adsorbent on the surface of the pick. After the spraying is completed, it is connected with the air pipe 11 through the negative pressure machine 2 to achieve the drying effect;

[0054] In this embodiment, the two ends of the guide slot 890 provided on the moving frame 89 are straight line segments, and the matching segment between the two straight line segments is arranged in an arc shape;

[0055] The mounting post 891 and the rotating wheel 892 are located on one side of the arc-shaped guide groove 890 .

[0056] By adopting the above technical solution, the driving motor 83 drives the T-shaped plate 80 to move along the guide column 81, so that the glass slide is placed in the sample solution tank 6, and then the T-shaped plate 80 is moved to place the dried or blown glass slide in the developer tank 7, wherein the immersion depth of the pick is effectively controlled, and the glass slide is taken out. At this time, the T-shaped plate 80 moves again to place the processed glass slide in the placement tank 9, and the chemical raw materials on the pick are detected and analyzed by the chromatographic analyzer 4;

[0057] Furthermore, when the device is testing chemical raw materials, the material is automatically loaded, sprayed and passed through the sample solution tank 6 and the developing agent tank 7 in sequence, thus reducing the manual participation. The chromatographic analyzer 4 realizes automatic detection and analysis of the sliding raw materials placed on the tank 9, greatly improving the work efficiency.

[0058] The working principle of the present invention is: when in use, the sample solution tank 6, the developing agent tank 7 and the placement tank 9 are placed in sequence, wherein the placement tank 9 is placed inside the chromatographic analyzer 4, so that the chromatographic analyzer 4 can effectively detect and analyze the raw materials on the glass slide;

[0059] During operation, a plurality of paddles are placed on the supporting columns 880 between the loading racks 88, and the suction cups 811 are driven to move by the flipping heads 810, so that the loading racks 88 can automatically rotate and load materials;

[0060] When loading, the electric push cylinder 85 fixedly installed on one side of the bottom plate 84 drives the slide block 87 to move upward along the slide frame 86. During the upward movement of the slide block 87, the fixed rod 870 drives the flip head 810 to move. At this time, the sleeve 871 arranged on the fixed rod 870 moves along the inner wall of the guide groove 890 provided on the moving frame 89. When the sleeve 871 passes through the arc section of the guide groove 890 through the fixed rod 870, the moving frame 89 swings slightly through the rotating shaft 812. During the swinging process of the moving frame 89, the rotating wheel 892 installed on the moving frame 89 cooperates with the sliding groove 8100 provided on the flip head 810, so that the flip head 810 rotates along the rotating wheel 892, and the flip head 810 reverses 180°, and then moves upward through the straight section of the guide groove 890, so that the suction cup 811 contacts the glass slide on the loading frame 88, and the glass slide is loaded.

[0061] After the loading is completed, the electric push cylinder 85 drives the slider 87 to move in the opposite direction, and the flip head 810 is reset through the cooperation with the moving frame 89, and the glass slide is moved to the working position. At this time, the pump body 5 is connected with the spray pipe 10 to spray the adsorbent on the surface of the pick. After the spraying is completed, it is connected with the air pipe 11 through the negative pressure machine 2 to achieve the drying effect;

[0062] Then, the driving motor 83 drives the T-shaped plate 80 to move along the guide column 81 to place the glass slide in the sample solution tank 6, and the cylinder 815 drives the bottom plate 84 to move upward as a whole, and moves the glass slide to one side of the air pipe 11 for drying. Then, the driving motor 83 drives the T-shaped plate 80 to move, and the dried or blown glass slide is placed in the developing agent tank 7. When the glass slide is immersed in the developing agent tank 7, the immersion depth is 0.5 cm. When the front edge of the developing agent is 1 cm away from the top of the glass slide, the glass slide is taken out. At this time, the T-shaped plate 80 moves again to place the processed glass slide in the placement tank 9, and the chemical raw materials on the pick are detected and analyzed by the chromatographic analyzer 4. The setting of the cylinder 815 effectively avoids the situation that there is a flip gap between the glass slide on the suction cup 811 during the flipping process of the flip head 810, thereby effectively ensuring that the glass slide is placed in the sample solution tank 6 and the developing agent tank 7.

[0063] When the device is testing chemical raw materials, the whole process is automatically loaded, sprayed and passed through the sample solution tank 6 and the developing agent tank 7 in sequence, thus reducing the manual participation, and the sliding raw materials on the placement tank 9 are automatically tested and analyzed by the chromatographic analyzer 4, which greatly improves the work efficiency.
