Description

Technical Field

[0001] This utility model relates to the technical field of aminobenzoic acid processing equipment, and more specifically, to a weighing device for p-aminobenzoic acid. Background Technology

[0002] In the production and experimental stages of p-aminobenzoic acid, accurate weighing of its powder is a crucial operation. Traditional weighing equipment faces numerous technical challenges when handling powdered p-aminobenzoic acid. On the one hand, the powder is easily affected by external airflow during the pouring process, such as indoor ventilation and airflow generated by personnel movement, causing the powder to scatter, resulting in material waste, potential pollution of the operating environment, and increased cleaning costs. On the other hand, powder is prone to accidental leakage during pouring, spilling onto the weighing equipment and surrounding areas, affecting weighing accuracy and increasing the cleaning burden on operators. Therefore, to address these issues, a p-aminobenzoic acid weighing device is proposed. Utility Model Content

[0003] To overcome the aforementioned deficiencies of the prior art, embodiments of this utility model provide a p-aminobenzoic acid weighing device. A rotating handle and a rotatably connected guard plate are located at the top of the weighing device body. When the powder is poured, the guard plate forms a physical barrier, blocking external airflow from disturbing the powder and preventing accidental powder leakage. Since the guard plate and the aminobenzoic acid powder container have no contact surface, they do not interfere with the natural weighing process of the container, ensuring the accuracy of the weighing data. The guard plate adopts a semi-circular arc design and is fixed in place by magnetic connection between magnetic blocks and magnetic grooves, ensuring the guard plate remains stable during weighing and powder handling, preventing displacement due to external impacts, and continuously providing protection.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a weighing device for para-aminobenzoic acid, comprising a weighing device body, an aminobenzoic acid powder container placed at the top of the weighing device body, a rotating handle fixedly connected to the top of the weighing device body, a protective plate rotatably disposed on the outside of the rotating handle, the protective plate being disposed above the aminobenzoic acid powder container, the protective plates being symmetrically arranged on the weighing device body, and both sets of the protective plates being rotatably connected to the rotating handle.

[0005] In a preferred embodiment, the protective plate is arranged in a semi-circular arc shape, and the annular diameter of the combination of the two sets of protective plates corresponds to the diameter of the container holding aminobenzoic acid powder. A magnetic block is fixedly connected to one end of one set of protective plates, and a magnetic groove is opened at one end of the other protective plate. The magnetic groove and the magnetic block are magnetically connected.

[0006] In a preferred embodiment, the guard plate has a movable groove inside, a push rod is movably disposed inside the movable groove, a spring is disposed inside the movable groove, and a scraper is fixedly connected to the push rod through the movable groove.

[0007] In a preferred embodiment, the bottom end of the scraper is wedge-shaped, and the scraper is in contact with the inner wall of the guard plate.

[0008] In a preferred embodiment, a stabilizing rod is fixedly connected inside the moving groove, and the stabilizing rod is slidably connected to the pushing rod. One end of the spring is fixedly connected to the pushing rod, and the other end of the spring is fixedly connected to the inner wall of the moving groove.

[0009] In a preferred embodiment, a pressing pad is fixedly connected to the top end of the push rod, and the pressing pad is made of rubber.

[0010] The technical effects and advantages of this utility model are as follows: The rotating handle and rotatably connected guard plate at the top of the weighing equipment body form a physical barrier when the powder is poured, blocking external airflow from disturbing the powder and preventing accidental powder leakage. Since the guard plate has no contact surface with the container holding the aminobenzoic acid powder, it does not interfere with the natural weighing process of the container, ensuring the accuracy of the weighing data. The guard plate adopts a semi-circular arc design and is fixed by magnetic connection between magnetic blocks and magnetic grooves, ensuring the guard plate remains stable during weighing and powder handling, preventing displacement due to external impacts, and continuously providing protection. The scraping and recycling structure composed of the moving groove, pushing rod, spring, and scraper inside the guard plate allows the operator to push the pushing rod after use, moving the scraper along the inner wall of the guard plate to scrape away and recycle any remaining powder. The wedge-shaped design at the bottom of the scraper ensures a tight fit with the inner wall of the guard plate, reaching into corners and gaps, improving scraping efficiency and reducing material waste.

[0016] 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.

[0017] Refer to the instruction manual appendix Figure 1-4 A weighing device for para-aminobenzoic acid includes a weighing device body 1, a container 2 for holding para-aminobenzoic acid powder placed at the top of the weighing device body 1, a rotating handle 3 fixedly connected to the top of the weighing device body 1, and a protective plate 4 rotatably mounted on the outside of the rotating handle 3. The protective plate 4 is positioned above the container 2 for holding para-aminobenzoic acid powder and is symmetrically arranged on the weighing device body 1. Both sets of protective plates 4 are rotatably connected to the rotating handle 3. In actual use, when pouring para-aminobenzoic acid powder, the powdered para-aminobenzoic acid will be poured into ammonia... During the process of placing aminobenzoic acid powder into container 2, the protective plate 4 can effectively block the flow of air. Specifically, the protective plate 4 can prevent external airflow from disturbing the powder and avoid the powder from being scattered due to the airflow. At the same time, it can prevent the powder from accidentally leaking out during pouring, reducing material waste and cleaning work. Since the protective plate 4 and the aminobenzoic acid powder container 2 only have a lid-and-guide relationship and there is no contact surface between them, it will not interfere with the natural weighing process of the aminobenzoic acid powder container 2, ensuring the accuracy of the weighing data.

[0018] The protective plates 4 are arranged in a semi-circular arc shape. The annular diameter of the two sets of protective plates 4 after combination corresponds to the diameter of the container 2 for aminobenzoic acid powder, and can completely cover the container 2. One set of protective plates 4 is fixedly connected to a magnetic block 5 at one end. The magnetic block 5 is made of neodymium iron boron permanent magnet material and has strong magnetism. The other set of protective plates 4 has a magnetic groove 6 at one end. The size of the magnetic groove 6 is adapted to the magnetic block 5, and a magnetic material with opposite polarity to the magnetic block 5 is embedded inside. When the two sets of protective plates 4 are assembled into a whole, the magnetic connection between the magnetic block 5 and the magnetic groove 6 is used to fix the protective plates 4, ensuring that the protective plates 4 can maintain a stable state during weighing and powder handling and will not shift due to slight external impacts or other factors.

[0019] The guard plate 4 has a movable groove 7 inside, which is a long, narrow groove extending along the arc of the guard plate 4. A push rod 8 is movable inside the movable groove 7. The push rod 8 has a cylindrical design, and its diameter matches the width of the movable groove 7, allowing it to slide flexibly within the groove 7. At the same time, a spring 11 is installed inside the movable groove 7. The spring 11 is made of stainless steel, which has good elasticity and corrosion resistance. After the push rod 8 passes through the movable groove 7, one end is fixedly connected to a scraper 9. The scraper 9 is made of hard plastic, which has good wear resistance and chemical stability. After use, the operator pushes the push rod 8 to move it within the movable groove 7, which in turn moves the scraper 9 along the inner wall of the guard plate 4 to scrape off and recover the residual aminobenzoic acid powder on the inner wall of the guard plate 4, effectively saving material costs.

[0020] The scraper 9 has a wedge-shaped bottom end, which allows it to fit tightly against the inner wall of the guard plate 4. As the scraper 9 moves with the push rod 8, the wedge-shaped bottom end can penetrate into the corners and gaps of the inner wall of the guard plate 4 to scrape away the residual powder as completely as possible. Compared with scrapers of ordinary shape, it has a better scraping effect.

[0021] To ensure the stability of the push rod 8 within the moving groove 7, a stabilizing rod 10 is fixedly connected inside the moving groove 7. The stabilizing rod 10 is a slender cylindrical rod, arranged parallel to the length direction of the moving groove 7. The push rod 8 has a through hole that matches the stabilizing rod 10, forming a sliding connection with the stabilizing rod 10 through the through hole. One end of the spring 11 is fixedly connected to the end of the push rod 8 near the scraper 9, and the other end is fixedly connected to the inner wall of the moving groove 7. When the push rod 8 moves within the moving groove 7, the stabilizing rod 10 acts as a guide and limiter, while the spring 11 provides a restoring force, ensuring that the push rod 8 can automatically reset after completing the scraping operation for easy use next time.

[0022] In addition, a pressing pad is fixedly connected to the top of the push rod 8. The pressing pad is made of rubber. The surface of the rubber pressing pad is designed with anti-slip texture. When the operator presses the push rod 8, it can increase the friction between the hand and the pressing pad, which can play an anti-slip and anti-drop effect, so that the operator can control the movement of the push rod 8 more easily and stably, and improve the convenience and efficiency of the scraping operation.
