Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid alkali detection technology, specifically an automatic sampling device. Background Technology
[0002] Liquid caustic soda is a major auxiliary material required for the company's production process. It is sold in various concentrations on the market, including 30%, 32%, 45%, 48%, and 50%. The quality of the liquid caustic soda directly affects the company's production efficiency and economic benefits; therefore, monitoring the quality of liquid caustic soda is one of the key points of the company's quality control management. The original liquid caustic soda quality control process was "manual on-site sampling + manual laboratory monitoring," with the results of multiple sampling and testing of a single vehicle representing the overall results.
[0003] For example, patent application number 202323278578.7 discloses an automatic sampling device. This utility includes a fixed base, on which is provided a sampling mechanism for driving a sampling tube to take samples and a rotating mechanism for facilitating the replacement or placement of the sampling tube by the operator. The rotating mechanism is located below the sampling mechanism. The sampling mechanism includes two sets of first clamping components, a lifting cylinder, and a mounting plate. The two sets of first clamping components are respectively installed on both sides of the mounting plate. The lifting cylinder drives the mounting plate to rise and fall. By using an automated mechanical structure to replace manual sampling of alkali solution, it effectively ensures the safety of workers and makes the sampling process more standardized, ensuring the accuracy of sampling and testing. However, this automatic sampling device requires two clamping operations during the sampling of liquid alkali. When performing large-scale and multiple sampling, it will increase the waiting time for the experimenter.
[0004] Therefore, in view of this, we studied and improved the existing structure to address its shortcomings and proposed an automatic sampling device. Utility Model Content

Detailed Implementation
[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 protection scope of the present utility model.
[0022] like Figures 1-3 As shown, an automatic sampling device includes a base 1, a support frame 101 on the upper surface of the base 1, and a drive motor 102 mounted on the lower surface of the support frame 101. A gear set 103 is provided at the output end of the drive motor 102, and a rotating rod 2 is provided on the upper surface of the gear set 103. Through the configuration of the drive motor 102 and the gear set 103, the drive motor 102 can drive the gear set 103 to rotate the rotating plate 201 to complete the precise angle adjustment, so that the test tube 4 can be accurately stopped below the alkaline solution to be poured for alkaline solution sampling.
[0023] Furthermore, a rotating plate 201 is provided on the upper surface of the rotating rod 2, and clamping components 1 202 are fixedly installed through both sides of the surface of the rotating plate 201, and clamping components 203 are fixedly installed through the middle of the surface of the rotating plate 201. The advantage of this arrangement is that by providing two clamping components 1 202 and clamping components 203 with opposite working strokes on both sides of the rotating plate 201, the sampling efficiency of the equipment can be improved.
[0024] Furthermore, the clamping assembly 202 includes a push cylinder 204 disposed on both sides of the surface of the rotating plate 201, and a clamping cylinder 205 is disposed at the output end of the push cylinder 204. A clamping plate 206 is disposed on the clamping surface of the clamping cylinder 205, and the clamping plate 206 and the clamping cylinder 205 are configured to be slidably connected. This configuration is existing in the device and will not be described in detail.
[0025] Furthermore, an anti-slip pad 100 is provided on the lower surface of the base 1, and the anti-slip pad 100 is circular for adhesive fixation. The advantage of this setting is that the placement stability of the base 1 can be improved by setting the anti-slip pad 100.
[0026] like Figure 4 As shown, a limiting slide rod 3 is slidably installed through the surface of the clamping plate 206, and a limiting plate 301 is provided at the end of the limiting slide rod 3 away from the clamping cylinder 205. The advantage of this setting is that, by setting the limiting slide rod 3, the sliding direction of the compression spring 302 can be limited by friction generated by sliding.
[0027] Furthermore, a compression spring 302 is provided on the outer circular surface of the limiting slide bar 3, and the compression spring 302 is fixedly connected to the clamping plate 206. The advantage of this setting is that, by setting the compression spring 302, the rubber clamping plate 303 of the pressing belt can further adhere to the test tube 4, preventing the test tube 4 from slipping off during the rotation of the rotating plate 201.
[0028] Furthermore, a rubber clamp 303 is provided at one end of the limiting slide bar 3 near the clamping cylinder 205, and a test tube 4 is clamped and installed on the inner surface of the rubber clamp 303. The advantage of this arrangement is that the friction between the rubber clamp 303 and the test tube 4 can be increased.
[0029] Working Principle: When using this automatic sampling device, firstly, the test tube 4 is placed in the middle of the clamping plate 206. The clamping cylinder 205 then moves the clamping plate 206 inwards, causing the rubber clamping plate 303 to adhere to the surface of the test tube 4, thus completing the clamping. Simultaneously, the compression spring 302 further compresses, ensuring the rubber clamping plate 303 adheres to the test tube 4. Next, the drive motor 102 drives the gear set 103 to rotate the rotating rod 2, moving the clamping component 1 202 on the rotating plate 201 into the alkali solution for sampling. While sampling, the test tube 4 is placed in the middle of the clamping plate 206 of the clamping component 2 203 for clamping. After clamping, the drive motor 102 resets the clamping component 1 202 on the rotating plate 201, moving the clamping component 2 203 into the alkali solution for sampling, repeating the sampling process. This is the working principle of the automatic sampling device.
