Description
Technical Field
[0001] This utility model relates to the field of drug preparation equipment technology, specifically to a raw material pulverizing device for preparing cilostazol tablets. Background Technology
[0002] Cilostazol tablets are an antiplatelet aggregation drug. During its preparation, the cilostazol raw material needs to be pulverized to meet certain particle size requirements to ensure the smooth progress of subsequent mixing, tableting and other processes, thereby ensuring the quality and efficacy of cilostazol tablets.
[0003] However, existing equipment for pulverizing cilostazol raw materials is usually a fully enclosed structure, with only the upper feed inlet and the lower discharge outlet exposed. After the pulverization process is completed, in order to prevent the residual slag inside from contaminating the proportion and purity of the next batch of raw materials, it is generally necessary to flush the inside. However, this fully enclosed structure makes it easy to create cleaning dead corners during the flushing process, making it difficult to see the internal cleaning situation. There is a high probability that some residue will still remain, which will have an adverse effect on the pulverization of the next batch of raw materials.
[0004] Therefore, it is necessary to provide a new raw material pulverizing device for the preparation of cilostazol tablets to solve the above-mentioned technical problems. Utility Model Content

[0018] The raw material pulverizing equipment for cilostazol tablet preparation includes: a pulverizing chamber 1 and two pulverizing rollers 9 rotatably installed inside the pulverizing chamber 1. The pulverizing chamber 1 has openings on both sides and the top, and a discharge port at the bottom. Two arc-shaped guide plates are fixedly installed on the inner walls of both sides of the pulverizing chamber 1, located between the upper cover 7 and the pulverizing rollers 9, which can smoothly guide the raw material to be pulverized onto the pulverizing rollers 9 for pulverization. A pulverizing motor is fixedly installed on the outer wall of one side of the pulverizing chamber 1, and its output shaft is fixedly connected to one end of one of the pulverizing rollers 9. The ends of both pulverizing rollers 9 away from the pulverizing motor extend outside the pulverizing chamber 1. Two crushing rollers 9 are each fixedly fitted with a first sprocket, which meshes with each other. Both first sprockets are located outside the crushing chamber 1. A U-shaped rotating frame 3 is provided on one side of the crushing chamber 1, with a crossbeam 4 fixedly installed on its top. A hydraulic cylinder 5 is fixedly installed on the bottom of the crossbeam 4, and a connecting frame 6 is fixedly installed on its output shaft. To ensure the stability of the hydraulic cylinder 5, two guide columns are slidably installed on the crossbeam 4, and the bottom ends of the two guide columns are fixedly connected to the connecting frame 6. An upper cover 7 is fixedly installed on the bottom of the connecting frame 6, and its bottom contacts the top of the crushing chamber 1 to form a sealing effect. A connecting frame 6 is fixedly installed on the top of the upper cover 7 by bolts. The feed hopper 8 inside the frame 6 is designed for easy disassembly and cleaning or replacement. A feed inlet is located on the upper cover 7, directly below the feed hopper 8. Side covers 15 are provided on both sides of the upper cover 7. Sealing gaskets 16 are fixedly installed on the sides of the two side covers 15 that are close to each other, and the sides of the two sealing gaskets 16 abut against the sides of the crushing chamber 1. L-shaped folding plates 10 are fixedly installed on the outer walls of both sides of the connecting frame 6. Cylinders 11 are fixedly installed on the inner walls of the sides of the two L-shaped folding plates 10 that are far apart from each other. Linkage bars 12 are fixedly installed on the output shafts of both cylinders 11. The bottoms of the two linkage bars 12 are fixedly... Hollow boxes 13 are fixedly installed. To ensure the stability of cylinder 11 operation, reinforcing crossbeams are fixedly installed on the inner walls of the two L-shaped folding plates 10 on the side away from each other. The ends of the two reinforcing crossbeams that are close to each other are fixedly connected to the outer walls of the two sides of the connecting frame 6. The two reinforcing crossbeams pass through the corresponding linkage bar 12 and are slidably connected to the corresponding linkage bar 12. The side away from each other and the bottom of the two hollow boxes 13 are set as openings. Rotating shafts 14 are rotatably installed in the two hollow boxes 13. The tops of the two side covers 15 extend into the two hollow boxes 13 respectively. The two rotating shafts 14 pass through the corresponding side covers 15 and are fixedly connected to the corresponding side covers 15.
[0019] In the above method, in order to remove the upper cover 7 and the side cover 15 from above the crushing box 1 and maximize the field of vision, an outer bracket 17 is fixedly installed on the support side plate 2 near the U-shaped rotating frame 3. A steering shaft 18 is rotatably installed on the outer bracket 17. A turntable is fixedly installed at the top of the steering shaft 18. The top of the turntable is fixedly connected to the U-shaped rotating frame 3. A first rotating motor is fixedly installed on the support side plate 2 near the U-shaped rotating frame 3. A second spherical gear is fixedly sleeved on both the output shaft and the steering shaft 18. The two second spherical gears mesh with each other. Four support feet are fixedly installed at the bottom of the turntable. The bottom end faces of the four support feet are all spherical, and the bottoms of the four support feet are in contact with the outer bracket 17, which plays a role in providing stable support.
[0020] In this method, in order to unfold the side cover 15 and make its rotation not interfered with by the crushing box 1, a second rotary motor is fixedly installed on one side of the outer wall of each of the two hollow boxes 13. The output shafts of the two second rotary motors are respectively fixedly connected to one end of the two rotary shafts 14. The side of the two side covers 15 that are close to each other are respectively attached to the inner wall of the side of the two hollow boxes 13 that are close to each other.
[0021] The working principle of the raw material pulverizing equipment for preparing cilostazol tablets provided by this utility model is as follows: In the initial state, the output shafts of hydraulic cylinder 5 and air cylinder 11 are both extended; When the equipment is performing raw material crushing operations normally, the raw material is fed into the feed hopper 8 and enters the crushing box 1 through the feed port on the upper cover 7. Under the guidance of the arc-shaped guide plate, it falls accurately between the two crushing rollers 9. The crushing motor starts, and its output shaft drives one of the crushing rollers 9 to rotate. Since the two crushing rollers 9 are fixedly fitted with the first sprockets that mesh with each other, the other crushing roller 9 rotates in the opposite direction under the transmission action of the first sprockets. The two crushing rollers 9 work together to crush the raw material, and the crushed raw material is discharged from the discharge port at the bottom of the crushing box 1. When it is necessary to clean the residue inside the crushing box 1, first start the cylinder 11 to retract its output shaft, thereby pulling the linkage bar 12 to move away from the crushing box 1. The linkage bar 12 drives the hollow box 13 and the side cover 15 to move synchronously until the sealing gasket 16 separates from the two sides of the crushing box 1, opening the two sides of the crushing box 1. During this process, the crossbeam plays a guiding and stabilizing role on the movement of the linkage bar 12, ensuring that the side cover 15 moves smoothly. Then, the hydraulic cylinder 5 is activated, causing its output shaft to retract, thereby pulling the connecting frame 6 upward. The connecting frame 6 drives the upper cover 7 and the feed hopper 8 to move upward synchronously, opening the top opening of the crushing box 1. At this time, the top and side openings of the crushing box 1 are opened. Next, the two second rotary motors are activated, and their output shafts drive the two rotary shafts 14 to rotate, thereby causing the two side covers 15 to unfold in opposite directions. Finally, the two side covers 15 are attached to the top inner walls of the two hollow boxes 13. At this time, the upper cover 7 and the two side covers 15 are located above the crushing box 1. Then, the first rotary motor is started in the forward direction. The meshing of the two second spur gears drives the steering shaft 18 to rotate, which in turn drives the U-shaped rotating frame 3 to rotate, thereby driving the entire upper cover 7 and the two side covers 15 to rotate until the upper cover 7 and the side covers 15 rotate away from the top of the crushing box 1 and then the first rotary motor is turned off. At this point, the separate crushing chamber 1, upper cover 7, and side cover 15 are fully exposed, allowing for direct cleaning of residues. After cleaning, the steps described above are reversed to return each component to its original position.
[0022] Compared with related technologies, the raw material pulverizing equipment for preparing cilostazol tablets provided by this utility model has the following beneficial effects: I. This utility model, through the set cylinder 11 and hydraulic cylinder 5, can control the opening and closing of the side cover 15 and the upper cover 7 respectively. Combined with the second rotary motor to unfold the side cover 15 and the first rotary motor to rotate the entire cover assembly, the crushing box 1 is fully exposed, which is convenient for intuitive cleaning of internal residues. There are no dead corners for cleaning, so it will not affect the crushing of different batches of raw materials. II. This utility model utilizes double crushing rollers 9 that rotate in opposite directions via gear transmission, and works in conjunction with an arc-shaped guide plate to precisely feed materials, thereby achieving efficient crushing and smooth discharge of raw materials and ensuring normal operating efficiency.
