DETAILED DESCRIPTION

The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.
[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0021] The utility model embodiment provides a device for quantitatively adding raw materials for drug synthesis, such as Figure 1-4 As shown, the device for quantitatively adding raw materials for drug synthesis includes: a lifting assembly plate 1, on which are arranged a plurality of material tanks 2 for storing raw materials for drug synthesis; a quantitative material valve 3 arranged at a discharge port at the bottom of the material tank 2; a feed pipe 4 fixedly installed on the discharge end of the quantitative material valve 3; a conveying cylinder 5 arranged on the discharge end of the feed pipe 4, on which a telescopic discharge pipe 6 is fixedly installed; a conveying mechanism arranged on the conveying cylinder 5 for conveying raw materials; and a stirring mechanism arranged on the material tank 2 for stirring the raw materials to prevent congestion.
[0022] It should be noted that in the process of drug synthesis, the precise addition of raw materials is a key factor in ensuring the quality of the final product and the efficiency of synthesis. Although there are some quantitative raw material addition devices on the market, which do improve the accuracy of raw material addition to a certain extent, these devices often have some obvious limitations in practical applications. Among them, the most prominent problem is the single-channel addition method. This design means that all raw materials need to be added through the same channel, without considering the possible differences in properties and interactions between different raw materials. In fact, different types of raw materials may have significant differences in their physical state, chemical properties and compatibility with other raw materials. When these raw materials are mixed together and added through the same channel, they are likely to have adverse interactions, resulting in changes in the properties of the raw materials, and may even trigger chemical reactions, thereby affecting the effect and safety of drug synthesis. In addition, the single-channel addition method may also cause cross-contamination between raw materials. In the continuous synthesis process, different batches or different types of raw materials often need to be added continuously in a short period of time. If only a single channel is relied on for addition, it is difficult to avoid the residue of the previous raw material from contaminating the next raw material, which will also have an adverse effect on the results of drug synthesis. Therefore, in order to overcome these problems, the utility model proposes a quantitative raw material addition device for drug synthesis.

At the same time, the controllability of the motor also enables the conveying speed of the raw material to be adjusted as needed, improving the flexibility of the device; the coupling 9 is assembled on the output rod of the first motor 8, and the other end is fixedly connected to one end of the shaft of the spiral conveying roller 7, playing a transmission role; the use of the coupling 9 ensures that the power of the first motor 8 can be smoothly and efficiently transmitted to the spiral conveying roller 7, avoiding the loss and fluctuation in the power transmission process, and improving the efficiency and stability of the entire conveying mechanism.

This design not only improves the stirring efficiency, but also enhances the uniformity of stirring, and further prevents the agglomeration and deposition of the raw materials.
[0028] In a further preferred embodiment of the utility model, a plurality of mounting seats 15 are symmetrically arranged below the assembly plate 1, and an electric telescopic rod 16 for regulating the lifting and lowering of the assembly plate 1 is fixedly installed on the top of the mounting seat 15, and the top of the output rod of the electric telescopic rod 16 is fixedly connected to the bottom of the assembly plate 1.

The symmetrical arrangement of the mounting seat 15 ensures the stability of the assembly plate 1 during the lifting process, and prevents shaking or tilting due to uneven force. At the same time, the solid structure of the mounting seat 15 also ensures the stability and reliability of the electric telescopic rod 16 during operation; the electric telescopic rod 16 is fixed to the top of the mounting seat 15, and the top end of its output rod is fixedly connected to the bottom of the assembly plate 1. By controlling the extension and retraction of the electric telescopic rod 16, precise control of the lifting and retraction of the assembly plate 1 can be achieved; the use of the electric telescopic rod 16 makes the lifting and retraction of the assembly plate 1 simple, convenient and precise.

This design not only improves the flexibility and adaptability of the device, but also reduces the difficulty of operation and improves work efficiency.
[0030] In a further preferred embodiment of the present invention, a universal wheel 17 for movement is fixedly mounted on the bottom of the mounting seat 15, and the universal wheel 17 is a brakeable type.
[0031] In this embodiment, the universal wheels 17 are fixedly mounted at the bottom of the mounting seat 15, so that the entire device can be easily moved on the ground. At the same time, these universal wheels 17 have a braking function, which can lock the position of the device when necessary to prevent it from sliding or moving; by adding universal wheels 17, the device can be easily moved to any desired position, greatly improving its flexibility and convenience. Whether it is transferred between different laboratories or moved between different synthesis reactors in the same laboratory, it can be achieved by simple pushing and braking, greatly reducing the trouble and cost of manual handling. In addition, the braking function ensures the stability of the device during operation, prevents the movement of the device due to misoperation or external factors, thereby ensuring the stability and safety of the drug synthesis process; when used in combination with the lifting mechanism of the lifting assembly plate 1, the introduction of the universal wheels 17 further enhances the adaptability and flexibility of the entire device.
