Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical raw material processing, and in particular to a screening device for pharmaceutical raw materials. Background Technology

[0002] Drugs are substances used to prevent, treat, and diagnose diseases. In theory, drugs refer to any chemical substance that can affect the physiological functions of organs and the metabolic activities of cells. Drug processing refers to the process by which drug raw materials are transformed into drug preparations with therapeutic effects through a series of technological processes. Drug processing involves the extraction, separation, purification, synthesis, preparation manufacturing, and quality control of drugs.

[0003] Traditional Chinese medicine (TCM) materials are diverse and widely sourced, each containing a variety of chemical components. Based on their pharmacological effects and composition, TCM materials can be broadly categorized into many types. When processing TCM materials into medicinal raw materials, they need to be cleaned and pulverized, followed by sieving to ensure uniformity of the crushed material. However, current sieving equipment often involves pouring the raw materials into the equipment all at once, causing them to accumulate on the screen and easily leading to clogging and affecting sieving efficiency. Therefore, we propose a new sieving device for medicinal raw materials to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a screening device for pharmaceutical raw materials to solve the problems mentioned in the background art.

[0006] A screening device for pharmaceutical raw materials includes a screening mechanism. Two toothed plates are fixedly mounted on the outer surface of the screening mechanism. A feeding hopper is provided above the screening mechanism. Two support plates are fixedly connected to the outer surface of the feeding hopper. A rotating shaft is rotatably connected inside the feeding hopper via bearings. Both ends of the rotating shaft pass through the feeding hopper and are rotatably connected to the support plates via bearings. Two gears are mounted on the outer surface of the rotating shaft. The outer surface of each gear meshes with the upper surface of the toothed plates. A drive motor is mounted on one side of one of the support plates. The output end of the drive motor is connected to one end of the rotating shaft. Multiple material-pulling plates are provided inside the feeding hopper. The outer surface of each material-pulling plate is connected to the outer surface of the rotating shaft.

[0007] In a further embodiment, the outer surface of the screening mechanism has two grooves, and each groove has a slider slidably connected inside it. The ends of the two sliders that are far apart from each other are connected to the inner wall of the support plate.

[0008] In a further embodiment, the screening mechanism includes a housing, a screen frame is installed on the inner wall of the housing, a screen mesh is installed inside the screen frame, and a vibration motor is installed on the bottom surface of the screen frame.

[0010] In a further embodiment, a slag discharge pipe is installed on the outer surface of the screening mechanism, and one end of the slag discharge pipe is connected to the machine casing.

[0011] In a further embodiment, a controller is mounted on the front of the screening mechanism, and the controller is electrically connected to a drive motor and a vibration motor via wires.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The screening mechanism of this device is equipped with a vibration motor, which causes the screen frame and screen to vibrate, promoting rapid grading and screening of drug raw materials. At the same time, the feeding hopper maintains stable movement during vibration through the meshing of gears and toothed plates, and the sliding cooperation design of the chute and slider, avoiding equipment deviation or jamming caused by vibration. By setting up a material-pushing plate and a drive motor, the feeding hopper drives the material-pushing plate to rotate during the feeding process, evenly dispersing the drug raw materials, preventing raw materials from accumulating on the screen, reducing the risk of blockage, and improving screening efficiency.

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.

[0022] Please see Figure 1-4 In this utility model, a screening device for pharmaceutical raw materials includes a screening mechanism 1. The screening mechanism 1 includes a housing 101. A sieve frame 102 is installed on the inner wall of the housing 101. A screen 103 is installed inside the sieve frame 102. A vibration motor 104 is installed on the bottom surface of the sieve frame 102. When the screening mechanism 1 is started, the vibration motor 104 in the housing 101 vibrates in coordination with the sieve frame 102. The sieve frame 102 screens the pharmaceutical raw materials through the screen 103. A slag discharge pipe 6 is installed on the outer surface of the screening mechanism 1. One end of the slag discharge pipe 6 is connected to the housing 101. Substances in the pharmaceutical raw materials that have not passed through the screen 103 are discharged along the slag discharge pipe 6. A collection frame is set at the bottom of the housing 101 to collect the pharmaceutical raw materials after screening.

[0023] Two toothed plates 8 are fixedly mounted on the outer surface of the screening mechanism 1. A feeding hopper 10 is provided above the screening mechanism 1. Two support plates 9 are fixedly connected to the outer surface of the feeding hopper 10. A rotating shaft 13 is rotatably connected inside the feeding hopper 10 via bearings. Both ends of the rotating shaft 13 pass through the feeding hopper 10 and are rotatably connected to the support plates 9 via bearings. Two gears 11 are mounted on the outer surface of the rotating shaft 13. The outer surface of each gear 11 meshes with the upper surface of the toothed plates 8. A drive motor 12 is mounted on one side of one of the support plates 9. The output end of the drive motor 12 is connected to one end of the rotating shaft 13. Multiple material-pushing plates 14 are provided inside the feeding hopper 10. The outer surface of each material-pushing plate 14 is connected to the outer surface of the rotating shaft 13. While the screening mechanism 1 is running, the drive motor 12 drives the gear 11 and the material-discharging plate 14 in the hopper 10 to rotate. The rotation of the material-discharging plate 14 cooperates with the material-discharging hopper 10 to discharge material. At the same time, the material-discharging hopper 10 can reciprocate along the top of the screening mechanism 1 with the cooperation of the gear 11 and the toothed plate 8, so as to enter and evenly disperse the drug raw materials, avoid the raw materials from accumulating on the screen 103, and reduce the risk of blockage. Two sliding grooves 7 are opened on the outer surface of the screening mechanism 1. A slider 2 is slidably connected inside each sliding groove 7. The ends of the two sliders 2 that are far apart from each other are connected to the inner wall of the support plate 9. Through the sliding grooves 7 and the sliders 2 cooperating with the support plate 9, the support plate 9 can cooperate with the material-discharging hopper 10 to slide and discharge material under the meshing action of the gear 11 and the toothed plate 8.

[0024] Two sets of support legs 4 are fixedly connected to the bottom of the screening mechanism 1. Each set of support legs 4 is fixedly connected to a support base 5 at its bottom. The equipment is installed through the support legs 4 and the support base 5. Fixing holes are provided on the support base 5 to facilitate the fixing of the equipment. A controller 3 is installed on the front of the screening mechanism 1. The controller 3 is electrically connected to the drive motor 12 and the vibration motor 104 through wires. The drive motor 12 is a servo motor. The controller 3 centrally controls the drive motor 12 and the vibration motor 104, and can adjust the vibration frequency and feeding speed to adapt to the screening requirements of different drug raw materials. The controller 3 can be programmed to control the drive motor 12 to rotate in both directions, so that the feeding hopper 10 reciprocates during feeding, reducing manual intervention and improving production efficiency.

[0025] The working principle of this utility model is as follows:

[0026] In use, the screening device is first supported by the support base 5 and the support leg 4. Then, the raw materials to be screened are poured into the feeding hopper 10. The screening mechanism 1 is started, and the vibration motor 104 in the housing 101 vibrates in conjunction with the screen frame 102. The screen frame 102 screens the raw materials through the screen 103. While the screening mechanism 1 is running, the drive motor 12 drives the gear 11 and the material-pulling plate 14 in the feeding hopper 10 to rotate. The rotation of the material-pulling plate 14 cooperates with the feeding hopper 10 to discharge the material. At the same time, with the cooperation of the gear 11 and the toothed plate 8, the feeding hopper 10 can reciprocate along the top of the screening mechanism 1 to uniformly disperse the raw materials, avoid the accumulation of raw materials on the screen 103, and reduce the risk of blockage.
