Description

Technical Field

[0001] The utility model relates to the technical field of screening of solid tablet raw and auxiliary materials, and particularly relates to a screening device for processing solid tablet raw and auxiliary materials. Background Technique

[0002] A screening device is a mechanical device used to separate and classify solid materials according to parameters such as particle size, density or shape. The performance and quality of tablets largely depend on the particle size distribution of their raw materials and auxiliary materials. Particle size uniformity is the basis for producing high-quality tablets. As one of the key devices for the pretreatment of raw materials and auxiliary materials, the performance and precision of the screening device directly affect the quality and stability of the final product. Therefore, using a screening device to screen solid tablet raw materials and auxiliary materials is one of the important measures to ensure product quality.

[0003] In the existing screening devices, the feeding position is fixed, that is, the material can only fall at the same position on the screen mesh. For example, the powder screening device disclosed in the patent with the publication number CN220005993U, in which the material enters the screening mechanism through the feeding port, but the position of the feeding port is fixed. The fixed feeding position will cause uneven thickness and density of the material on the screen mesh, thereby affecting the screening effect. At the same time, due to the uneven distribution of the material, the material in some areas may be fully screened, while the screening capacity in other areas of the screen mesh may not be fully utilized, resulting in waste of resources. Being under the impact of the material at a fixed position for a long time will cause increased wear of this area of the screen mesh and shorten the service life of the screen mesh.

[0004] Therefore, it is necessary to invent a screening device for processing solid tablet raw and auxiliary materials to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a screening device for processing solid tablet raw and auxiliary materials to solve the problem in the technology that the material can only be concentrated and sent to a certain position, resulting in uneven distribution of the material and affecting the screening effect.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A screening device for processing solid tablet raw and auxiliary materials, including a screening box body, a support platform, a feeding mechanism, an X-axis moving mechanism and a screening mechanism. A support platform is arranged above the screening box body, and a feeding mechanism is arranged above the support platform. The feeding mechanism includes a storage hopper, the storage hopper is fixedly installed on the support platform, a feeding port is arranged at the bottom of the storage hopper, a spiral auger is arranged inside the feeding port, an X-axis moving mechanism is arranged below the support platform, the X-axis moving mechanism includes a second motor, the second motor is arranged on one side of the outer wall of the screening box body, a second bevel gear assembly is arranged on the second motor, a reciprocating lead screw is arranged on the second bevel gear assembly, and a screening mechanism is arranged inside the screening box body.

[0007] Preferably, the feeding mechanism further includes a first motor disposed outside the storage hopper. The output end of the first motor is fixedly connected to a rotating shaft, and a first bevel gear assembly is fixedly installed on the rotating shaft. By providing power through the first motor to drive the rotation of the rotating shaft, the active feeding function of the feeding mechanism is realized.

[0008] Preferably, the first bevel gear assembly is located at the top of the storage hopper. The first bevel gear assembly is composed of two meshing bevel gears. One of the bevel gears is connected to the rotating shaft, and the other bevel gear is connected to the driving end of the screw auger. The first bevel gear assembly is used to realize the vertical conversion of power, so that even if the first motor is installed outside the storage hopper, it can effectively drive the screw auger located below it.

[0009] Preferably, the second bevel gear assembly is composed of two meshing bevel gears. One of the bevel gears is connected to the output end of the second motor, and the other bevel gear is connected to the reciprocating lead screw. The second bevel gear assembly cooperates with the second motor to realize the vertical conversion of power and drive the reciprocating lead screw to rotate.

[0010] Preferably, there are 2 reciprocating lead screws. The two reciprocating lead screws are located at the front and rear ends outside the screening box body. A support platform is threadedly connected to the reciprocating lead screw, and the side wall of the support platform is slidably connected to the screening box body. By the rotation of the reciprocating lead screw, the support platform and the feeding mechanism thereon are driven to perform horizontal reciprocating movement. This design helps to evenly distribute the position of the material on the sieve, improving the screening efficiency and uniformity.

[0011] Preferably, the screening mechanism includes a first sieve and a second sieve. Both the first sieve and the second sieve are arranged inside the screening box body. The first sieve and the second sieve are designed to be inclined. The first sieve is arranged above the second sieve. The inclined design of the first sieve and the second sieve enables the material to slide naturally, accelerating the screening speed and at the same time reducing the accumulation and blockage of the material on the sieve.

[0012] Preferably, one end of the first sieve is provided with a first discharge port through the side wall of the screening box body, and one end of the second sieve is provided with a second discharge port through the side wall of the screening box body. The aperture of the first sieve is larger than that of the second sieve, realizing the classification screening of the material, meeting the requirements for separating materials with different particle sizes, and improving the purity and quality of the product.

[0013] Preferably, a vibration motor is provided at the bottom of the No. 1 screen and the No. 2 screen, and the vibration force generated by the vibration motor helps the material to separate and slide on the screen faster, thereby improving the screening efficiency and effect. At the same time, the vibration can also effectively prevent the screen from being blocked, and maintain the continuity and stability of the screening process.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] 1. Through the setting of the spiral auger, a spiral auger is set inside the discharge port. Through the rotation of the spiral blade, the spiral auger can smoothly push the material and can continuously transport the material from the discharge port to the designated position, ensuring the continuity and stability of the production process, avoiding the blockage and accumulation of materials during the transportation process, and ensuring the transportation efficiency;

[0016] 2. Through the setting of the X-axis moving mechanism, the X-axis moving mechanism can drive the feeding port to perform left and right reciprocating or continuous linear motion above the screen, so as to ensure that the material falls into the screen evenly from multiple positions. This uniform material distribution method effectively avoids excessive accumulation of materials at a certain position of the screen, so that each sieve hole on the screen can be fully utilized, thereby improving the screening efficiency and screening quality. The uniform material distribution reduces the burden on the local area of ​​the screen, and avoids the local wear of the screen caused by excessive concentration of materials.

[0024] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] The present invention provides a screening device for processing raw and auxiliary materials of solid tablets as shown in Figures 1-5 Figure 10, which includes a screening box 1. A support platform 2 is arranged above the screening box 1. A feeding mechanism 3 is arranged above the support platform 2. The feeding mechanism 3 includes a storage hopper 301. The storage hopper 301 is fixedly installed on the support platform 2. A discharge opening 302 is arranged at the bottom of the storage hopper 301. A screw auger 306 is arranged inside the discharge opening 302. An X-axis moving mechanism 4 is arranged below the support platform 2. The X-axis moving mechanism 4 includes a second motor 401. The second motor 401 is arranged on one side of the outer wall of the screening box 1. A second bevel gear assembly 402 is arranged on the second motor 401. A reciprocating lead screw 403 is arranged on the second bevel gear assembly 402. A screening mechanism 5 is arranged inside the screening box 1.

[0026] The feeding mechanism 3 further includes a first motor 303. The first motor 303 is arranged outside the storage hopper 301. The output end of the first motor 303 is fixedly connected with a rotating shaft 304. A first bevel gear assembly 305 is fixedly installed on the rotating shaft 304. The first bevel gear assembly 305 is located at the top of the storage hopper 301. The first bevel gear assembly 305 is composed of two meshing bevel gears. One of the bevel gears is connected to the rotating shaft 304, and the other bevel gear is connected to the driving end of the screw auger 306.

[0027] The feeding mechanism 3 is a key part to ensure the continuous and uniform feeding of materials into the screening box 1. When the first motor 303 is started, it drives the rotating shaft 304 to rotate, and then transmits the power to the screw auger 306 through the first bevel gear assembly 305, so that the screw auger 306 rotates at the bottom of the storage hopper 301, pushes the materials to move downward, and enters the screening box 1 through the discharge opening 302. Through the coordinated work of the first motor 303 and the screw auger 306, the stable and continuous feeding of materials is realized, and the accumulation and blockage of materials in the storage hopper 301 are avoided.

[0028] The second bevel gear assembly 402 consists of two meshing bevel gears. One bevel gear is connected to the output end of the second motor 401, and the other bevel gear is connected to the reciprocating lead screw 403. There are 2 reciprocating lead screws 403, which are located at the front and rear ends outside the screening box body 1. A support platform 2 is threadedly connected to the reciprocating lead screw 403, and the side wall of the support platform 2 is slidably connected to the screening box body 1.

[0029] One reciprocating lead screw 403 is provided at each of the front and rear ends outside the screening box body 1. The support platform 2 is threadedly connected to the two reciprocating lead screws 403. When the second motor 401 is started, it drives the reciprocating lead screw 403 to rotate through the second bevel gear assembly 402, so that the support platform 2 and the feeding mechanism 3 thereon perform horizontal reciprocating movement above the screening box body 1. Through the reciprocating movement of the support platform 2, the materials under the feeding mechanism 3 can be evenly distributed on the first sieve mesh 501, improving the uniformity and efficiency of screening. The reciprocating movement helps to reduce the accumulation and blockage of materials on the first sieve mesh 501.

[0030] The screening mechanism 5 includes a first sieve mesh 501 and a second sieve mesh 503. Both the first sieve mesh 501 and the second sieve mesh 503 are arranged inside the screening box body 1. The first sieve mesh 501 and the second sieve mesh 503 are designed to be inclined. The first sieve mesh 501 is arranged above the second sieve mesh 503. One end of the first sieve mesh 501 is provided with a first discharge port 502 through the side wall of the screening box body 1, and one end of the second sieve mesh 503 is provided with a second discharge port 504 through the side wall of the screening box body 1. The aperture of the first sieve mesh 501 is larger than that of the second sieve mesh 503. A vibration motor 505 is arranged at the bottom of the first sieve mesh 501 and the second sieve mesh 503.

[0031] The screening mechanism 5 is the core part of the solid tablet raw material processing and screening equipment. Through the different aperture designs of the first sieve mesh 501 and the second sieve mesh 503, the classification screening of materials is realized, meeting the requirements for separating materials with different particle sizes. Moreover, the inclined designs of the first sieve mesh 501 and the second sieve mesh 503 and the application of the vibration motor 505 enable the materials to pass through the sieve holes faster during the screening process, improving the screening efficiency. And the vibration effect of the vibration motor 505 helps to prevent the sieve holes from being blocked, ensuring the continuity and stability of the screening process.

[0032] The working principle of the present utility model:

[0033] Refer to the attached instruction manual Figures 1-2, when using the present utility model, first add the solid tablet raw materials into the storage hopper 301, start the first motor 303 to drive the rotation of the rotating shaft 304, and the first bevel gear assembly 305 on the rotating shaft 304 transmits the rotational power to the spiral auger 306. The spiral auger 306 rotates at the bottom of the storage hopper 301, pushes the material to move downward, and evenly discharges it through the feeding port 302 above the screening box body 1. Synchronously start the second motor 401 to drive the rotation of the second bevel gear assembly 402. The second bevel gear assembly 402 transmits the rotational power to the reciprocating lead screw 403, so that the two reciprocating lead screws 403 rotate synchronously. The support platform 2 is on the reciprocating lead screw 403 and makes a horizontal reciprocating movement above the screening box body 1 as the reciprocating lead screw 403 rotates. In this way, the material at the feeding port 302 is evenly distributed inside the screening box body 1;

[0034] Refer to the attached instruction manual Figures 3-5 , when using the present utility model, when the material falls into the screening box body 1, it first contacts the first screen 501. The vibration motor 505 is started to drive the vibration of the first screen 501 and the second screen 503. The material smaller than the aperture of the first screen 501 falls onto the second screen 503, while the material with a larger particle size remains on the first screen 501 and slides down along the first screen 501 to be discharged from the first discharge port 502. And the material on the second screen 503 is further screened. In this way, the material remaining on the second screen 503 slides down along the second screen 503 to be discharged from the second discharge port 504, thereby realizing the screening work of the solid tablet raw materials.
