Description

Technical Field

[0001] This utility model relates to the field of drug feeding technology, specifically a precise feeding structure for the synthesis of an important drug intermediate. Background Technology

[0002] Pharmaceutical intermediates are key chemical substances produced during the synthesis of active pharmaceutical ingredients (APIs). They are an important step in the preparation of the final active pharmaceutical ingredient. They are usually produced from basic chemicals through a series of reactions (such as esterification, nitration, reduction, etc.) and have specific chemical structures and functional groups. The addition of pharmaceutical intermediates is a critical step in the synthesis process. The order, speed and reaction conditions of the addition of materials must be strictly controlled to make the processing more efficient and convenient.

[0003] According to the feeding mechanism in a pharmaceutical intermediate reaction with application number CN202120215400.X, this solution solves the problems of delaying the cleaning time of the staff and reducing the protection of the entire device.

[0004] However, the following problems still exist in actual use:

[0005] During feeding, the screw feed roller is driven directly by a motor. However, the amount of material fed cannot be uniformly controlled, and the angle of discharge cannot be repeatedly changed to control the amount of material fed. This leads to the accumulation of raw materials after feeding, affecting the processing effect. Furthermore, the qualified parts of the raw materials cannot be screened during feeding, which will affect subsequent processing operations and hinder the efficient operation of the equipment.

[0006] Therefore, this utility model introduces a precise feeding structure for the synthesis of important drug intermediates. Utility Model Content

[0007] To address the shortcomings of existing technologies, this invention provides a precise feeding structure for the synthesis of important pharmaceutical intermediates. It has the advantages of being able to simultaneously control the feeding and discharge, and is able to collect and process unqualified raw materials after screening, thus solving the problems mentioned in the background technology.

[0008] This utility model provides the following technical solution: a precise feeding structure for the synthesis of an important pharmaceutical intermediate, comprising a feeding box, a linkage control mechanism provided on the back of the feeding box, the linkage control mechanism comprising a rotating rod, a conveying blade, a pulley, a transmission belt, a pulley, a rotating rod, and an adjusting plate. The outer surface of the rotating rod is rotatably connected to the inner wall of the feeding box. One side of the conveying blade is fixedly installed to the outer surface of the rotating rod. The inside of the pulley is fixedly installed to the outer surface of the rotating rod. The inner ring of the transmission belt is drively connected to the outer surface of the pulley. The outer surface of the pulley is drively connected to the inner ring of the transmission belt. The outer surface of the rotating rod is fixedly installed to the inside of the pulley. The inside of the adjusting plate is fixedly installed to the outer surface of the rotating rod.

[0009] Preferably, a screen is fixedly installed inside the feeding box, and a blocking block is engaged inside the feeding box.

[0010] Preferably, a discharge box is fixedly installed inside the feeding box, and the inner wall of the discharge box is rotatably connected to the outer surface of the rotating rod.

[0013] Preferably, the adjusting plate is disposed inside the discharge box, and the discharge box is fixedly installed on the left side inside the feeding box.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The precise feeding structure in the synthesis of this important drug intermediate achieves stable feeding and precise adjustment of raw materials through the linkage control of the conveyor blades and the adjustment plate driven by the servo motor. This ensures that the feeding amount is controllable during the synthesis of the drug intermediate, improves reaction accuracy, and adopts a linkage mechanism of pulley one, pulley two and transmission belt to make the conveyor blades and adjustment plate move synchronously, reduce mechanical errors, and ensure the continuity and stability of the feeding process. This solves the problem of how to link feeding with the adjustment of discharge, making the equipment more convenient to use, reducing energy consumption, and reducing the complexity of actual operation.

[0016] 2. The precise feeding structure in the synthesis of important drug intermediates features a sieve that filters out large particles or lumps in the raw materials, ensuring uniform particle size of the material entering the conveyor blades, avoiding blockages or uneven feeding, and improving the reaction consistency of drug intermediate synthesis.

This solves the problem of how to feed raw materials after sieving, and can avoid excessive impurities during feeding, further improving the reliability and cleanliness of the feeding structure.

[0022] 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.

[0023] Please see Figure 3A precise feeding structure for the synthesis of an important pharmaceutical intermediate includes a feeding box 1. A linkage control mechanism 15 is located on the back of the feeding box 1. The linkage control mechanism 15 includes a rotating rod 8, a conveying blade 9, a pulley 10, a transmission belt 11, a pulley 12, a rotating rod 13, and an adjusting plate 14. The outer surface of the rotating rod 8 is rotatably connected to the inner wall of the feeding box 1. One side of the conveying blade 9 is fixedly installed to the outer surface of the rotating rod 8. The inside of the pulley 10 is fixedly installed to the outer surface of the rotating rod 8. The inner ring of the transmission belt 11 is drively connected to the outer surface of the pulley 10. The pulley 12... The outer surface of the rotating rod 13 is connected to the inner ring of the transmission belt 11. The outer surface of the rotating rod 13 is fixedly installed inside the pulley 12. The inner surface of the adjusting plate 14 is fixedly installed to the outer surface of the rotating rod 13. The discharge box 5 is fixedly installed inside the feeding box 1. The inner wall of the discharge box 5 is rotatably connected to the outer surface of the rotating rod 13. An L-shaped plate 6 is fixedly installed on the back of the feeding box 1. A servo motor 7 is fixedly installed on the back of the L-shaped plate 6. The output shaft of the servo motor 7 is fixedly connected to one end of the rotating rod 8. The adjusting plate 14 is located inside the discharge box 5, and the discharge box 5 is fixedly installed on the left side inside the feeding box 1.

[0024] By controlling the speed and running time of the servo motor 7, the number of rotations and conveying volume of the conveying blade 9 can be precisely controlled. Simultaneously, the pulley 10 on the rotating rod 8 drives the pulley 12 via the transmission belt 11, causing the rotating rod 13 and the adjusting plate 14 to rotate accordingly. The adjusting plate 14 is located inside the discharge box 5, and its rotation angle can adjust the size of the discharge port of the discharge box 5, thereby further controlling the discharge volume. The rotating rod 8 is rotatably connected to the inner wall of the feeding box 1, and the rotating rod 13 is rotatably connected to the inner wall of the discharge box 5. This design provides stable support for the rotating components, reducing swaying and deviation during rotation.

[0025] Please see Figure 4 A screen 3 is fixedly installed inside the feeding box 1, and a blocking block 4 is snapped into the inside of the feeding box 1.

[0026] The screen 3 is fixedly installed inside the feeding box 1. When the material is added to the feeding box 1, it will pass through the screen 3. The screen 3 has a specific aperture, which only allows material particles that meet the requirements to pass through, while larger impurities, lumps, etc. will be blocked above the screen 3. The block block 4 is attached to the inside of the feeding box 1 and can be installed or removed at any time according to production needs. It can be used for centralized processing of unqualified raw materials.

[0027] Please see Figure 1 and Figure 2 The feeding port 2 is located on the right side of the upper surface of the feeding box 1.

[0028] This design facilitates the entry of raw materials into the feeding box 1, making feeding more convenient.

[0029] Working principle: During use, the servo motor 7 is started by the electrical connection of an external power source, enabling it to rotate in both directions. After starting the servo motor 7, it drives the rotating rod 8 to rotate, which in turn drives the conveying blades 9 fixed on it to rotate synchronously. This conveys the raw materials fed into the feeding box 1 through the inlet 2 to the left. At the same time, the rotating rod 8 transmits power to the rotating rod 13 through a belt drive system consisting of a fixed pulley 10, a transmission belt 11, and a pulley 12. This causes the adjusting plate 14 fixed on the rotating rod 13 to reciprocate within the discharge box 5. After being filtered by the screen 3, the raw materials are pushed to the discharge box 5 area by the conveying blades 9. At this time, the rotating adjusting plate 14 achieves precise quantitative feeding by reciprocating the discharge channel, avoiding material blockage. The blockage block 4 can be removed from the inside of the feeding box 1 to collect the raw materials that fail to pass the sieve.
