Description

Technical Field

[0001] This utility model relates to the field of chemical experiment and pharmaceutical research and development technology, specifically a quantitative dispensing device for chemical impurity reference standards. Background Technology

[0002] Chemical impurity reference standards play a crucial role in many fields such as drug development and quality control. Their purity and the precision of their dosage have a decisive impact on experimental results.

[0003] Existing dispensing methods are mostly manual, which has many drawbacks. On the one hand, manual weighing makes it difficult to ensure consistent dispensing accuracy each time. Due to factors such as the precision of weighing tools and human error, deviations in the amount of reference standard used are easily caused. For example, in some high-precision detection experiments, even small differences in dosage can lead to significant deviations in experimental results. On the other hand, manual dispensing is inefficient, and for applications requiring large-scale dispensing, it is time-consuming and labor-intensive. Therefore, a quantitative dispensing device for chemical impurity reference standards is needed to improve upon these problems. Utility Model Content

[0004] To address the numerous drawbacks of existing manual dispensing methods, which rely heavily on manual operation, the following points are crucial. Firstly, manual weighing makes it difficult to guarantee consistent dispensing accuracy each time. Factors such as the precision of weighing tools and human error can easily lead to deviations in the dosage of reference standards. For example, in some high-precision testing experiments, even slight differences in dosage can cause significant deviations in experimental results. Secondly, manual dispensing is inefficient, time-consuming, and labor-intensive for applications requiring large-scale dispensing. The purpose of this invention is to provide a quantitative dispensing device for chemical impurity reference standards to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A quantitative dispensing device for chemical impurity reference standards includes a main body, a movable component disposed on the top of the main body, and a conveying component fixedly connected to the top of the main body.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] For examples, please refer to Figures 1-4 This utility model provides a technical solution: A quantitative dispensing device for chemical impurity reference standards includes a main body 1, a moving component 2 disposed on the top of the main body 1, and a conveying component 3 fixedly connected to the top of the main body 1.

[0019] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the main body 1 includes a support base 101, with a mounting groove 104 on its side. The moving component 2 includes a telescopic rod 201, with a connecting plate 202 driven to the output end of the telescopic rod 201. A slider 203 is fixedly connected to the side of the connecting plate 202, and a bearing plate 204 is fixedly connected to the top of the slider 203. The conveying component 3 includes a mounting plate 301, with a mounting hole 304 inside the mounting plate 301. A conveying cylinder 305 is welded to the mounting hole 304, and a motor 306 is mounted on the side of the conveying cylinder 305. The output end of the motor 306 is driven to a screw conveyor 307 via a coupling. By using the motor 306 to drive the screw conveyor 307, continuous material conveying can be achieved. As long as the material is continuously supplied, the conveying process will not be interrupted. Compared with intermittent conveying methods, this continuity greatly improves the material conveying efficiency. The screw conveyor 307 uses spiral blades for feeding, which can maintain high-efficiency conveying performance under various material forms and working conditions. It can effectively transport materials in powder, granular, or small block form.

[0020] The conveying cylinder 305 is fixedly connected to the side of the discharge hopper 308. The spiral conveying rod 307 is rotatably supported inside the conveying cylinder 305. The top of the mounting plate 301 is provided with an inlet 302. The top of the conveying cylinder 305 is provided with a connecting port 303. The inlet 302 and the connecting port 303 are connected. There are two sliders 203. The bearing plate 204 is inserted with a dispensing container 205. Several dispensing containers 205 are provided. The support base 101 is provided with a sliding groove 103. The slider 203 slides in the sliding groove 103. The support base 101 is provided with a limiting groove 105. The connecting plate 202 is slidably supported in the limiting groove 105 by the slider 203. The telescopic rod 201 is installed inside the mounting groove 104. The telescopic rod 201 can achieve precise telescopic control and thus drive the bearing plate 204 to move to the set precise position. This ensures that the dispensing container 205 is always accurately positioned directly below the discharge hopper 308, avoiding inaccurate material dispensing due to container position deviation.

[0021] In this embodiment, as Figure 1 and Figure 3 As shown, the bottom of the support base 101 is fixedly connected with an anti-slip pad 102. There are four anti-slip pads 102. Using the anti-slip pads 102 can ensure the stability of the equipment during operation, which helps to improve work efficiency and operating accuracy, and also reduces the safety hazards caused by the equipment sliding.

[0022] The working process of this utility model is as follows: When using the quantitative dispensing device for chemical impurity reference standards designed in this scheme, the dispensing containers 205 are placed on the support plate 204 according to the number and specifications of the containers to be dispensed. If the container layout needs to be adjusted, the position of the support plate 204 can be moved by controlling the extension and retraction of the telescopic rod 201. Through the extension and retraction control of the telescopic rod 201, the slider 203 slides within the slide groove 103, thereby moving the support plate 204 and accurately moving the first dispensing container 205 directly below the discharge hopper 308. During dispensing, the motor 306 is started, driving the screw conveyor 307 to rotate. The chemical impurity reference standards are sequentially fed into the conveying cylinder 305 through the inlet 302 and the connecting port 303. The screw conveyor 307 rotates within the conveying cylinder 305, beginning the conveying of the chemical impurity reference standards. The material moves forward along the spiral blades of the screw conveyor 307 and is finally discharged from the discharge hopper 308, entering the dispensing container 205 below. Due to the continuous conveying performance of the screw conveyor 307, the material can be discharged stably and continuously from the discharge hopper 308, completing the filling of the first filling container 205. Once the first filling container 205 is full, the telescopic rod 201 is extended or retracted again, causing the support plate 204 to move and move the next filling container 205 directly below the discharge hopper 308. The motor 306 is then started again to fill the next filling container 205. This process is repeated until all filling containers 205 are filled with chemical impurity reference standards.

[0023] The telescopic rod 201 and motor 306 used in this utility model are both existing known electrical devices, and both can be purchased and used directly on the market. Their structure, circuit and control principle are all existing known technologies. Therefore, the structure, circuit and control principle of the telescopic rod 201 and motor 306 will not be described in detail here.

[0024] All standard parts used in this application can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art and are also general components, which are common knowledge in this field.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
