Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical processing, specifically a vibrating screen for pharmaceutical processing. Background Technology

[0002] The pharmaceutical manufacturing process consists of two parts: the production of active pharmaceutical ingredients (APIs) and the production of pharmaceutical formulations. During the production of APIs, most drugs require cleaning, pulverizing, grinding, and sieving before being synthesized into finished pharmaceutical products. The main purpose of sieving is to remove larger particles after pulverization, thus making the drug raw materials finer and facilitating subsequent processing.

[0003] Vibrating screens are used in the manufacturing process of pharmaceuticals. The beating action of the vibrating screen causes the material to continuously tumble and stratify on the screen surface, increasing the contact opportunity between fine particles and the screen mesh, effectively improving screening efficiency. This is especially true for moist or sticky materials that are prone to clogging the screen. To further improve efficiency, existing vibrating screens have multi-layered screens. Users need to place the powder into the screen mesh before placing it into the vibrating screen for screening. Due to the stacked screens and the powder inside, the screens are quite heavy, making placement cumbersome. Furthermore, the stacked screens are prone to collapse if the center of gravity is unstable during handling, causing inconvenience to the user in processing the pharmaceuticals. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, current vibrating screens have multiple layers of screens. When using them, users need to put the powder into the screens and then place the screens into the vibrating screen to sieve the medicine. Because of the stacked screens and the powder inside, the screens are quite heavy, making it cumbersome to place them into the vibrating screen. Furthermore, the stacked screens are prone to collapse if the center of gravity is unstable during handling, causing inconvenience to the user in processing the medicine. This invention proposes a vibrating screen for pharmaceutical processing.

An insert plate 201 is fixedly connected to one side of the first support plate 203. By setting up the feeding mechanism 2, the user can easily feed the screen into the receiving plate 6 when using the vibrating screen body 1 to sieve the medicinal powder. This avoids the instability and collapse of the stacked screens caused by the user moving them, thus preventing waste of medicinal powder and achieving the purpose of conveniently feeding the screen into the receiving plate 6.

[0023] Reference Figure 2 A baffle 8 is fixedly connected to the top of the receiving plate 6, and a suction cup 11 is fixedly connected to one side of the baffle 8. There are several suction cups 11. By setting the baffle 8 and the suction cups 11, the screen can be limited and adsorbed, thereby increasing the stability of the screen.

[0024] Reference Figure 4 Both sides of the receiving plate 6 are fixedly connected to the housing 10. The inner wall of the housing 10 is provided with a limiting pin 14. One end of the limiting pin 14 passes through to the outside of the housing 10 and is fixedly connected to a pull ring 15. By setting the baffle 8 and the suction cup 11 in cooperation, the screen fed into the receiving plate 6 can be limited and adsorbed, thereby increasing the stability and firmness of the screen in the receiving plate 6 and preventing the screen from shifting.

[0025] Reference Figure 4 One end of the limiting pin 14 is fixedly connected to a pin head 12. One end of the pin head 12 passes through the housing 10 and the receiving plate 6 in sequence and is movably connected to the inner wall of the support column 3. Limiting plates 17 are fixedly connected to both sides of the limiting pin 14. A spring 13 is sleeved on the surface of the limiting pin 14. One end of the spring 13 is in close contact with one side of the limiting plate 17, and the other end of the spring 13 is in close contact with the inner wall of the housing 10. By setting the pin head 12, the receiving plate 6 can be limited, increasing the stability and firmness of the receiving plate 6. By setting the limiting plate 17 and the spring 13 in cooperation, the limiting pin 14 can be reset after movement, thus facilitating the user to fix the receiving plate 6 again.

[0026] Reference Figure 4The support column 3 has several limiting holes 9. The inner cavity of the limiting hole 9 is in contact with the surface of the pin head 12. By setting the limiting hole 9, the pin head 12 can be inserted into the limiting hole 9 under the action of the limiting hole 9, thereby fixing the receiving plate 6. This increases the stability and firmness of the receiving plate 6 during use and achieves the purpose of facilitating the insertion of the pin head 12 into the support column 3 to limit the position of the receiving plate 6.

[0027] Reference Figure 4 The inner wall of the receiving plate 6 is provided with a circular hole 18, and the inner cavity of the circular hole 18 is movably connected to the surface of the pin head 12. The inner wall of the housing 10 is provided with a movable hole 16, and the inner cavity of the movable hole 16 is movably connected to the surface of the limiting pin 14. By providing the circular hole 18, the pin head 12 can easily pass through the receiving plate 6 under the action of the circular hole 18, thereby limiting the receiving plate 6. By providing the movable hole 16, the movement of the limiting pin 14 can be provided with a trajectory under the action of the movable hole 16, so as to avoid the limiting pin 14 from getting stuck when moving.

[0028] Reference Figure 1 The inner wall of the base 7 is provided with two mounting grooves 5. The inner cavity of the mounting groove 5 is fixedly connected to the surface of the first electric telescopic rod 205. By setting the mounting groove 5, the user can easily install the first electric telescopic rod 205 in the base 7, which increases the stability and firmness of the first electric telescopic rod 205 during use and achieves the purpose of making it convenient for the user to install the first electric telescopic rod 205 in the base 7.

[0029] Working Principle: When sieving the powder, the user first places the stacked screens into the insert plate 201, ensuring the screens are in contact with the push plate 204. Then, the user starts the vibrating screen body 1. Next, the user activates the first electric telescopic rod 205 via an external power supply and switch. The telescopic end of the first electric telescopic rod 205 moves the first support plate 203 and the second support plate 206. The moving insert plate 201 moves the screens with the assistance of the push plate 204. When the screens move above the base 7, they contact the roller 4. The roller 4 facilitates smoother movement of the screens. When the screens reach the receiving plate 6, the user activates the second electric telescopic rod 202 via an external power supply and switch. The telescopic movement of the second electric telescopic rod 202 moves the push plate 204, causing the screens to move closer to the baffle 8. The screen is adsorbed by the disc 11, which increases the stability and firmness of the screen in the receiving plate 6. To facilitate the user's adjustment of the position of the receiving plate 6, the user pulls the pull ring 15. The movement of the pull ring 15 drives the limit pin 14 to move. The moving limit pin 14 drives the pin head 12 to disengage from the limit hole 9. At the same time, the moving limit pin 14 drives the limit plate 17 to compress the spring 13. The compressed spring 13 deforms, which increases the movement space of the limit pin 14. After the pin head 12 is completely moved out of the limit hole 9, the limit of the receiving plate 6 can be released. When the position of the receiving plate 6 is adjusted to a suitable position, the user releases the pull ring 15, so that the limit pin 14 and the pin head 12 enter another limit hole 9 under the push of the reaction force of the spring 13, which can fix the moved receiving plate 6, thereby fixing the screen placed in the receiving plate 6.

[0030] It should be noted that the body 1 of the impact-type vibrating screen is existing technology.
