Description

Technical Field

[0001] This utility model belongs to the field of screening equipment technology, and in particular relates to a screening equipment for coarse-particle building blocks. Background Technology

[0002] Coarse-grained lumps are solid, irregularly shaped lumps or granules formed by the aggregation of drug molecules due to their inherent characteristics or process influences during drug research and production. These substances are not single drug molecule forms, but rather coarse-grained aggregates formed by the aggregation of drug molecules. Their particle sizes often vary significantly and may contain lumps far exceeding standard sizes or non-compliant fine powders. Because the particle size of a drug directly affects its subsequent application efficacy and safety, uneven particle size can lead to large differences in the rate of drug dissolution, thus affecting the body's absorption efficiency and causing unstable efficacy. At the same time, excessively large coarse particles may be difficult to mix uniformly during formulation, leading to inaccurate drug dosage and increasing the risk of drug use. Sieving can screen out drug molecule particles that meet the size standard, remove excessive lumps and impurity powders, ensure stable drug quality and accurate dosage, and meet the strict requirements for uniformity of drug molecule particles in clinical use or subsequent production processes.

[0003] However, existing screening equipment often uses rotation for screening. During rotation, the material forms a relatively fixed trajectory inside the equipment. If there is adhesion or impurities between the particles, it is difficult to break the accumulation state by rotation, thus affecting the screening effect. Utility Model Content

[0004] The purpose of this utility model is to provide a coarse particle block screening device. By setting up a shaking part, it solves the problem that existing screening devices often use rotation to screen during use. During rotation, the material forms a relatively fixed movement trajectory inside the device. If there is adhesion or impurities between the particles, it is difficult to break the accumulation state by rotation, thus affecting the screening effect.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a coarse particle block screening device, comprising a support frame, and further comprising: a main body mounted on the support frame; a swaying part mounted on the right side of the support frame; a limiting part mounted on the main body; the swaying part comprising a swaying assembly mounted on the support frame; and a driving assembly mounted on the right side of the support frame; the swaying assembly comprising two guide rails fixedly connected to the inner wall of the right side of the support frame, each guide rail having a sliding rod slidably connected to its inner wall, a movable ring fixedly connected to the left side of each sliding rod, and a plurality of toothed blocks fixedly connected to the top of the movable ring, with a transmission component positioned above the plurality of toothed blocks; the plurality of toothed blocks are arranged in a linear array.

[0007] Furthermore, the main body includes a rotating shaft 1 rotatably connected to the inner walls of the left and right sides of the support frame, and a housing is fixedly connected between the two rotating shafts 1; the housing is disposed above the support frame, and the transmission component includes a gear fixedly connected to the outer wall of the right rotating shaft 1, the gear being adapted to a plurality of tooth blocks 1; the gear is located above the moving ring.

[0008] Furthermore, the limiting part includes a disassembly and assembly component installed inside the housing; and a limiting component installed at the bottom of the rotating shaft; the disassembly and assembly component is used for disassembly and assembly, and the limiting component is used for limiting.

[0009] Furthermore, the drive assembly includes a motor fixedly connected to the right side of the support frame. The output shaft of the motor is fixedly connected to a second rotating shaft via a coupling. The left side of the second rotating shaft extends into the support frame. A half gear is fixedly connected to the outer wall of the second rotating shaft. Several second tooth blocks are fixedly connected to the inner wall of the moving ring. The several second tooth blocks are located on the top inner wall and bottom inner wall of the moving ring, respectively, and each of the several second tooth blocks is adapted to the half gear.

[0010] Furthermore, the disassembly and assembly assembly includes a screen disposed inside the housing, with guide rails two fixedly connected to the left and right sides of the screen, and sliding rods two slidably connected to the outer walls of the two guide rails two; the two sliding rods two are fixedly connected to the housing on opposite sides, and the two sliding rods two are respectively located on the left and right sides of the screen.

[0012] This utility model has the following beneficial effects:

[0013] 1. By setting up a shaking part, the motor can drive the half gear to cooperate with the tooth block two, allowing the moving ring to move left and right under the restriction of the guide rail one and the slide rod one. Then, with the cooperation of the tooth block one and the gear, the shell and screen shake, thereby breaking the relatively fixed motion state of the material, making it easier to disperse the sticky particles and break up the accumulation of impurities. This allows the coarse particles of the drug molecules to come into more full contact with the screen, reducing the situation of incomplete screening caused by accumulation. It also allows for more flexible adjustment of the distribution and stratification of the material in the screen, further optimizing the screening effect and avoiding the impact of accumulation problems during rotation on screening efficiency and quality.

By setting a limiting part, the arc-shaped guide rail and arc-shaped limiting rod can guide the movement direction of the shell when it shakes, avoiding structural damage caused by shell displacement. At the same time, it ensures that the screen shakes stably with the shell, ensuring that the material always moves within the effective screening area during the screening process, reducing the impact of uncontrolled shell shaking on the screening effect. The screen can be reinstalled by the cooperation of guide rail two and slide rod two. The operation is convenient and the positioning is accurate. The equipment can be quickly reset to prepare for the next screening.

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.

[0025] Please see Figure 1-5 As shown, this utility model is a coarse particle block screening device, including a support frame 111, and further including: a main body 1, which is mounted on the support frame 111, the main body 1 including a rotating shaft 112 rotatably connected to the inner walls of the left and right sides of the support frame 111 respectively, and a housing 113 fixedly connected between the two rotating shafts 112; the housing 113 is disposed above the support frame 111; a swaying part 2, which is mounted on the right side of the support frame 111; and a limiting part 3, which is mounted on the main body 1.

[0026] The swaying part 2 includes a swaying assembly 21, which is mounted on the support frame 111; and a driving assembly 22, which is mounted on the right side of the support frame 111. The swaying assembly 21 includes two guide rails 211 fixedly connected to the inner wall of the right side of the support frame 111. Slide rods 212 are slidably connected to the inner walls of both guide rails 211. Moving rings 213 are fixedly connected to the left side of the two slide rods 212. Several toothed blocks 214 are fixedly connected to the top of the moving rings 213. A transmission component is provided above block 214; several toothed blocks 214 are arranged in a linear array. The drive assembly 22 includes a motor 221 fixedly connected to the right side of the support frame 111. The output shaft of the motor 221 is fixedly connected to a rotating shaft 222 via a coupling. The left side of the rotating shaft 222 extends into the support frame 111. A half gear 223 is fixedly connected to the outer wall of the rotating shaft 222. Several toothed blocks 224 are fixedly connected to the inner wall of the moving ring 213. The several toothed blocks 224 are respectively located on the moving ring 213. The top and bottom inner walls of the moving ring 213 have several toothed blocks 224 that are adapted to the half gear 223. The transmission component includes a gear 215 fixedly connected to the outer wall of the right rotating shaft 112. The gear 215 is adapted to several toothed blocks 214. The gear 215 is located above the moving ring 213. By setting the wobbling part 2, the motor 221 can drive the half gear 223 to cooperate with the toothed blocks 224, allowing the moving ring 213 to move left and right under the restriction of the guide rail 211 and the slide rod 212. The movement, aided by the engagement of toothed block 214 and gear 215, causes the housing 113 and screen 311 to shake, thereby breaking the relatively fixed motion state of the material. This makes it easier to disperse adhering particles and break up the accumulation of impurities, allowing the coarse drug molecule particles to come into more full contact with the screen 311. This reduces incomplete screening caused by accumulation, allows for more flexible adjustment of the distribution and stratification of the material within the screen 311, further optimizes the screening effect, and avoids the impact of accumulation during rotation on screening efficiency and quality.

[0027] The limiting part 3 includes a disassembly and assembly component 31, which is installed inside the housing 113; and a limiting component 32, which is installed at the bottom of the rotating shaft 112. The disassembly and assembly component 31 is used for disassembly and assembly, and the limiting component 32 is used for limiting. The disassembly and assembly component 31 includes a screen 311 disposed inside the housing 113. Guide rails 312 are fixedly connected to the left and right sides of the screen 311. Sliding rods 313 are slidably connected to the outer walls of the two guide rails 312. The sides of the two sliding rods 313 that are far apart from each other are fixedly connected to the housing 113. The two sliding rods 313 are located on the left and right sides of the screen 311, respectively. The limiting component 32 includes two arc-shaped guide rails 32 fixedly connected to the outer wall of the support frame 111. 1. Two arc-shaped guide rails 321 are slidably connected to the inner walls of each of the two arc-shaped guide rails 321. Both arc-shaped guide rails 322 are fixedly connected to the outer wall of the housing 113. By setting the limiting part 3, the arc-shaped guide rails 321 and the arc-shaped guide rails 322 can guide the movement direction of the housing 113 when it shakes, avoiding structural damage to the housing 113 due to displacement. At the same time, it ensures that the screen 311 shakes stably with the housing, ensuring that the material always moves within the effective screening area during the screening process, reducing the situation where the screening effect is affected by the uncontrolled shaking of the housing. The screen 311 can be reinstalled by the cooperation of the guide rail 2 312 and the slide bar 2 313. The operation is convenient and the positioning is accurate. The equipment can be quickly reset to prepare for the next screening.

[0028] It should be noted that the control of motor 221 in this application can be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be implemented using existing technologies, such as PLC.

[0029] A specific application of this embodiment is as follows: In use, firstly, the coarse drug molecule particles to be screened are placed into the screen 311. Then, the motor 221 is started, causing it to drive the half gear 223 to rotate via the second rotating shaft 222. At this time, the second toothed block 224 will cooperate with the half gear 223, causing the moving ring 213 to move left and right under the constraints of the first guide rail 211 and the first sliding rod 212. During this process, the first toothed block 214 will also cooperate with the gear 215, causing the housing 113 to shake via the first rotating shaft 112, which in turn causes the screen 311 to shake, thus sieving the coarse drug molecule particles. During sieving, particles smaller than the sieve holes on sieve 311 will pass through the sieve holes and fall into the housing 113, while particles larger than the sieve holes on sieve 311 will remain inside sieve 311. During the shaking of housing 113, arc-shaped guide rail 321 and arc-shaped limiting rod 322 will guide and limit housing 113. After sieving, sieve 311 is removed. Then, small particles and coarse particles are removed from housing 113. Then, larger particles and coarse particles are removed from sieve 311. Then, guide rail 2 312 is inserted into slide rod 2 313, and sieve 311 is placed back into housing 113.
