Description

Technical Field

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

[0002] In the pharmaceutical manufacturing industry, raw material screening is a key pretreatment step to ensure the purity, uniformity, and stability of drugs and subsequent processes. Although existing raw material screening equipment, such as vibrating screens and rotary screens, is widely used, there are still several technical bottlenecks that need to be addressed in actual production.

[0003] First, the screening efficiency and accuracy are insufficient. Traditional screening machines mostly use a single screen for primary screening, which is difficult to meet the process requirements of multi-stage and fine grading of raw materials. If multi-stage screening is required, multiple machines usually need to be connected in series or a complex multi-layer screen box needs to be used. This not only increases the equipment footprint and cost, but also easily causes cross-contamination and material loss during material transfer, and the process is interrupted, making continuous operation impossible. In addition, a single vibration or rotation mode can easily lead to uneven distribution of raw materials on the screen, resulting in material accumulation. Fine particles cannot effectively contact the screen holes, resulting in incomplete screening and low yield of qualified raw materials.

[0004] Secondly, screen clogging is a prominent problem, and the operation is unstable. Pharmaceutical raw materials are often sticky or clump together due to moisture, which easily clogs the screen holes during the screening process. Existing methods mostly rely on passive methods such as vibration or bouncing ball impact to clean the screen, which have limited effectiveness. Once clogging occurs, it will not only drastically reduce screening efficiency and output, but also require frequent shutdowns for manual cleaning, seriously interrupting the production process and increasing the labor intensity of operators. In addition, some pharmaceutical raw materials are not broken up during screening, making them difficult to screen. In view of this, this utility model provides a pharmaceutical raw material screening and processing device. Utility Model Content

[0005] The purpose of this application is to provide a pharmaceutical raw material screening and processing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a pharmaceutical raw material screening and processing device, comprising a processing frame and a processing box installed inside the frame, a screening disc movably disposed on the top of the processing box, a screening cylinder connected to the bottom of the screening disc via an arc-shaped rod, a rotary motor fixedly installed at the bottom of the processing box, a rotating rod fixedly installed at the output end of the rotary motor, a rotating gear fixedly installed on the rotating rod, and a rotating tooth block fixedly installed on the outer periphery of the top of the screening cylinder, wherein the rotating tooth block and the rotating gear are movably meshed; A support frame is fixedly installed on the top of the processing box. Inside the support frame is a swing assembly for sieving and moving the raw materials inside the sieving disc. The swing assembly includes a U-shaped support plate, a rotating disc, and a U-shaped swing rod. The U-shaped support plate is fixedly installed inside the support frame. A fixed rotating rod is movably connected to one end of the U-shaped support plate near the sieving disc. The U-shaped swing rod is fixedly installed on the fixed rotating rod. A connecting rotating rod is movably connected to the center of the end of the U-shaped support plate away from the sieving disc. The rotating disc is fixedly installed at one end of the connecting rotating rod, and a first bevel gear is fixedly installed at the other end of the connecting rotating rod. A T-shaped swing rod is movably connected to the U-shaped swing rod, and the T-shaped swing rod moves within the rotating disc.

[0007] Preferably, an arc-shaped discharge hopper is fixedly installed at the bottom of the processing box, and a discharge pipe with a valve is connected to the bottom of the screening cylinder, with the discharge pipe movably passing through the bottom of the arc-shaped discharge hopper.

[0008] Preferably, the top of the processing box is provided with a T-shaped groove, and a T-shaped slip ring that matches the T-shaped groove is fixedly installed on the outer periphery of the screening disc, and the T-shaped slip ring moves in the T-shaped groove.

[0009] Preferably, the bottom of the screening disc is provided with a plurality of first screening holes evenly distributed, and the bottom of the screening cylinder is provided with a plurality of second screening holes evenly distributed around its perimeter, wherein the inner diameter of the first screening holes is a multiple of the inner diameter of the second screening holes.

[0010] Preferably, the top end of the rotating rod extends through into the interior of the support frame, and a second bevel gear is fixedly installed on the top end of the rotating rod, and the second bevel gear is movably engaged with the first bevel gear.

[0011] Preferably, a swing plate is fixedly installed on the side of the fixed rotating rod away from the rotating disk, and the swing plate moves at the top of the screening disk. A plurality of arc-shaped connecting rods are evenly installed on the swing plate, and a plurality of actuating rods are evenly installed at the bottom of the arc-shaped connecting rods, and the actuating rods move in the screening disk.

[0012] Preferably, the support frame has a movable groove on the side near the screening disc, and the swing rod moves within the movable groove.

[0013] In summary, the technical effects and advantages of this utility model are as follows: 1. In this utility model, the reciprocating swing of the lever deep inside the screening disc creates dynamic sorting and disturbance of the material layer, effectively breaking up the raw material clumps that are easily formed during the initial screening and promptly cleaning particles that may be stuck in the first screening holes. This achieves a self-cleaning effect to actively prevent screen blockage, ensuring continuous and stable operation of the screening process. The swinging action of the component forces the raw material to be continuously redistributed and turned over on the screen surface, increasing the contact opportunity between each particle and the screening holes, allowing fine particles to pass through the screen holes more quickly and evenly, thereby significantly shortening the screening time and improving the utilization rate of the screening disc and the single-pass throughput.

[0014] 2. In this utility model, by setting up screening discs and screening cylinders with different apertures and using centrifugal force as the main driving force, forced and highly efficient multi-stage screening of pharmaceutical raw materials is achieved. This ensures that particles of different sizes can be accurately separated at different levels, significantly improving screening accuracy and the purity of finished products. The entire screening process, from preliminary screening to secondary fine screening and then to residue discharge, is automatically completed in the continuous operation of the rotating mechanism. The material flows naturally by gravity and centrifugal force, without the need for intermediate transfer or manual intervention, which greatly improves production efficiency.

[0020] See Figures 1-5An arc-shaped discharge hopper 12 is fixedly installed at the bottom of the processing box 11. A discharge pipe 13 with a valve is connected to the bottom of the screening cylinder 22, and the discharge pipe 13 moves through the bottom of the arc-shaped discharge hopper 12.

The inner diameter of the first screening hole 23 is 1.2 times the inner diameter of the second screening hole 24.

[0021] See Figures 1-5 The top end of the rotating rod 31 extends through into the interior of the support frame 40, and a second bevel gear 33 is fixedly installed at the top end of the rotating rod 31. The second bevel gear 33 is movably meshed with the first bevel gear 34. A swing plate 46 is fixedly installed on the side of the fixed rotating rod 42 away from the rotating disk 44.

This application does not elaborate on the existing structures and technologies.

[0022] The working principle of this utility model is as follows: The raw materials to be screened are added to the screening disc 20. The rotary motor 30 is started, driving the rotating rod 31 to rotate. The rotating rod 31 drives the screening cylinder 22 to rotate via the rotating gear 32 and rotating tooth block 25. The screening cylinder 22 drives the screening disc 20 to rotate synchronously via the arc-shaped rod 21. The bottom of the screening disc 20 has a first screening hole 23. The raw materials are initially screened within the screening disc 20, with larger particles retained and smaller particles falling into the screening cylinder 22 below through the first screening hole 23. The bottom of the screening cylinder 22 has a second screening hole 24 around its perimeter. When the screening cylinder 22 rotates, the raw materials inside are thrown against the cylinder wall under centrifugal force. Smaller particles are discharged through the second screening hole 24, achieving secondary screening. The remaining larger raw materials are discharged through the discharge pipe 13, achieving multi-stage screening of the raw materials and improving the screening effect. The top end of the rotating rod 31 extends into the support frame 40 and is fixedly mounted with a second bevel gear 33. The second bevel gear 33 meshes with the first bevel gear 34 in the swing assembly. Therefore, the rotation of the rotating rod 31 will drive the first bevel gear 34 to rotate. The first bevel gear 34 is fixedly connected to the rotating disk 44 through the connecting rod 35, thereby causing the rotating disk 44 to rotate. A T-shaped swing rod 45 is movably connected inside the rotating disk 44. The other end of the T-shaped swing rod 45 is movably connected to the U-shaped swing rod 43. The U-shaped swing rod 43 is mounted on the U-shaped support plate 41 through the fixed rotating rod 42. The fixed rotating rod 42 is also fixed with... When the rotating disk 44 rotates, the swing plate 46, through the transmission of the T-shaped swing rod 45, causes the U-shaped swing rod 43 to generate a reciprocating swing motion, which in turn drives the swing plate 46 to swing at the top of the screening disk 20. The arc-shaped connecting rod 47 and the multiple actuating rods 48 at the bottom of the swing plate 46 are evenly installed on the swing plate 46 and penetrate into the screening disk 20 as the swing plate 46 swings, continuously agitating and stirring the raw materials in it. The reciprocating swing motion effectively breaks up the raw material clumps, prevents the clogging of the screening holes, and promotes a more uniform distribution of the raw materials in the screening disk 20, thereby greatly improving the efficiency and quality of the initial screening.

[0023] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
