Abstract
Description
Technical Field
[0001] This utility model relates to the field of pharmaceutical granule production, specifically a screening device for continuous pharmaceutical granule production equipment. Background Technology
[0002] Screening is an important step in the production of pharmaceutical granules. Screening is the process of separating materials of different particle sizes into two or more parts with relatively uniform particle size using a screen tool. In continuous production equipment for pharmaceutical granules, screening is usually carried out by using single or multiple layers of screens to classify the mixed pharmaceutical granules according to particle size in order to obtain a product with uniform particle size that meets production requirements.
[0003] Particle sieving can effectively remove impurities such as coarse particles, foreign objects, or fine powder from raw materials, improving the purity and quality of the product. Generally, when sieving pharmaceutical granules, the sieving screen is vibrated up and down or moved horizontally back and forth. However, using only up and down vibration or horizontal back and forth movement is not very effective. While horizontal back and forth movement can achieve sieving, it is easy for the sieving screen to get stuck due to larger particles or impurities, further affecting the sieving effect. Utility Model Content
[0004] The screening effect of using only up-and-down vibration or horizontal reciprocating movement to screen medicine granules is not high. At the same time, although horizontal reciprocating movement can achieve the screening effect, the screening screen is prone to being stuck due to large particles or impurities, which further affects the screening effect. In order to overcome the shortcomings of the existing technology, this utility model proposes a screening device for continuous production equipment of medicine granules.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a screening device for a continuous production equipment of pharmaceutical granules, including a processing box, an installation box fixedly connected to one side of the processing box, a dual-shaft motor fixedly connected to the inner cavity of the installation box, a movable box slidably connected to the inner cavity of the processing box, a screening box slidably connected to the inner cavity of the movable box, a first screening mechanism provided on one side of the screening box, and a second screening mechanism provided in the inner cavity of the processing box;
[0006] The first screening mechanism includes a rotating disk. One side of the rotating disk is fixedly connected to the output of a dual-axis motor. A connecting rod is fixedly connected to the top of the rotating disk. A connecting plate is rotatably connected to the surface of the connecting rod. An installation rod is rotatably connected to the inner cavity of the connecting plate. A fixing plate is rotatably connected to the bottom of the installation rod. One side of the fixing plate is fixedly connected to one side of the movable housing. A drive assembly is provided at the bottom of the rotating disk.
[0007] Preferably, the second screening mechanism includes a rotating rod, one end of which is rotatably connected to the inner cavity of the processing box. A cam is fixedly connected to the surface of the rotating rod. A fixing block is fixedly connected to the inner cavity of the moving box. A mounting plate is fixedly connected to the bottom of the fixing block. A rotating roller is rotatably connected to the inner cavity of the mounting plate.
[0008] Preferably, the drive assembly includes a drive rod, one end of which is fixedly connected to the output end of a dual-axis motor. A first bevel gear is fixedly connected to the surface of the drive rod, and one end of the rotating rod passes through the processing box and the mounting box and is fixedly connected to a second bevel gear. The teeth of the first bevel gear mesh with the teeth of the second bevel gear.
[0009] Preferably, a limiting block is fixedly connected to the inner cavity of the processing box, a slider is fixedly connected to one side of the movable box, a groove is provided on the top of the limiting block, and the surface of the slider is slidably connected to the inner cavity of the groove.
[0010] Preferably, the inner cavity of the movable box is provided with a limiting groove, and a limiting block is fixedly connected to one side of the screening box, with the surface of the limiting block slidingly connected to the inner cavity of the limiting groove.
[0011] Preferably, a reinforcing ring block is fixedly connected to one side of the processing box, the inner cavity of the reinforcing ring block is rotatably connected to the surface of the rotating rod, and a reinforcing hollow block is fixedly connected to the surface of the fixing plate, with one side of the reinforcing hollow block fixedly connected to one side of the movable box.
[0012] Preferably, a reinforcing plate is fixedly connected to the inner cavity of the mounting box, the inner cavity of the reinforcing plate is rotatably connected to the surfaces of the drive rod and the rotating rod, and a rubber block is movably bonded to the inner cavity of the limiting groove.
[0013] The advantages of this utility model are:
[0014] This invention utilizes a dual-axis motor to simultaneously drive a rotating disk and a drive rod. The rotation of the rotating disk drives the sieving box and the moving box to reciprocate through a connecting plate and a fixed plate. The rotation of the drive rod, through the meshing of a first bevel gear and a second bevel gear, drives a cam to rotate, thereby enabling the sieving box to move up and down simultaneously during reciprocating motion. This achieves a significant improvement in sieving efficiency by combining reciprocating motion with up-and-down vibration when sieving medicinal particles, and reduces the clogging caused by larger particles and impurities. It solves the problems of low sieving efficiency when using only up-and-down vibration or horizontal reciprocating motion, and the tendency for the sieving screen to become stuck due to larger particles or impurities, further affecting the sieving effect, even though horizontal reciprocating motion can achieve sieving.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0025] This application discloses a screening device for a continuous pharmaceutical granule production system. (Refer to...) Figure 1 and Figure 2 A screening device for a continuous production line of pharmaceutical granules includes a processing box 1, a mounting box 2 fixedly connected to one side of the processing box 1, a dual-shaft motor 3 fixedly connected to the inner cavity of the mounting box 2, a movable box 4 slidably connected to the inner cavity of the processing box 1, a screening box 5 slidably connected to the inner cavity of the movable box 4, a first screening mechanism 6 provided on one side of the screening box 5, and a second screening mechanism 7 provided in the inner cavity of the processing box 1.
[0026] The first screening mechanism 6 includes a rotating disk 601. One side of the rotating disk 601 is fixedly connected to the output of the dual-axis motor 3. A connecting rod 602 is fixedly connected to the top of the rotating disk 601. A connecting plate 603 is rotatably connected to the surface of the connecting rod 602. An installation rod 604 is rotatably connected to the inner cavity of the connecting plate 603. A fixing plate 605 is rotatably connected to the bottom of the installation rod 604. One side of the fixing plate 605 is fixedly connected to one side of the movable housing 4. A drive assembly 606 is provided at the bottom of the rotating disk 601.
[0027] The processing box 1 serves to install and connect the mounting box 2 and the movable box 4. The screening box 5 inside the movable box 4 temporarily stores the granules and, through its subsequent vibration, screens them. The dual-shaft motor 3, through one of its output ends, drives the rotating disk 601 to rotate. The rotating disk 601, connected to the connecting plate 603 and the mounting rod 604 via the connecting rod 602, smoothly moves the mounting rod 604 and the fixed plate 605 connected to one end of the mounting rod 604. The continuous rotation of the rotating disk 601 causes the fixed plate 605 and the movable box 4 to reciprocate, thus enabling the movable box 4 to smoothly drive the screening box 5 to reciprocate as well, achieving the screening of the granules.
[0028] Reference Figure 2 and Figure 3 The second screening mechanism 7 includes a rotating rod 701, one end of which is rotatably connected to the inner cavity of the processing box 1. A cam 702 is fixedly connected to the surface of the rotating rod 701. A fixing block 703 is fixedly connected to the inner cavity of the movable box 4. A mounting plate 704 is fixedly connected to the bottom of the fixing block 703. A rotating roller 705 is rotatably connected to the inner cavity of the mounting plate 704. When the rotating rod 701 is driven to rotate by the drive assembly 606, it can smoothly drive the cam 702 to rotate together. The screening box 5 can use the fixing block 703 to control the mounting plate 704 and the cam 702. The rotating roller 705 is connected, and because the screening box 5 and the moving box 4 are slidably connected, the cam 702 can lift the screening box 5 through the rotating roller 705 when it rotates, and the screening box 5 can fall smoothly by its own weight. Then, through the continuous rotation of the rotating rod 701, the screening box 5 is vibrated. While the screening box 5 is moving back and forth, it can further improve the screening of drug particles through its own vibration. At the same time, through up and down vibration, the drug particles or impurities stuck inside the screening box 5 are reduced.
[0029] Reference Figure 2 and Figure 4The drive assembly 606 includes a drive rod 6061, one end of which is fixedly connected to the output end of the dual-axis motor 3. A first bevel gear 6062 is fixedly connected to the surface of the drive rod 6061. One end of the rotating rod 701 passes through the processing box 1 and the mounting box 2 and is fixedly connected to a second bevel gear 6063. The teeth of the first bevel gear 6062 and the teeth of the second bevel gear 6063 mesh with each other. The drive rod 6061 is connected to the other output end of the dual-axis motor 3. Through the operation of the dual-axis motor 3, the drive rod 6061 and the first bevel gear 6062 connected to the surface of the drive rod 6061 are smoothly driven to rotate. When the first bevel gear 6062 rotates, it can use the connection between itself and the second bevel gear 6063 to smoothly drive the rotating rod 701 to rotate while the rotating disk 601 rotates. This allows the first screening mechanism 6 and the second screening mechanism 7 to operate simultaneously, improving the screening effect of the screening box 5.
[0030] Reference Figure 4 and Figure 6 A limiting block 8 is fixedly connected to the inner cavity of the processing box 1, and a slider 10 is fixedly connected to one side of the movable box 4. A groove 9 is provided on the top of the limiting block 8, and the surface of the slider 10 is slidably connected to the inner cavity of the groove 9. The limiting block 8 can provide a certain support for the movable box 4, so that it is not easy to slip or fall when it moves. The connection between the groove 9 and the slider 10 can effectively limit the movement of the movable box 4, so that it can be stable enough when it moves back and forth.
[0031] Reference Figure 5 and Figure 6 The inner cavity of the movable box 4 is provided with a limiting groove 12, and a limiting block 13 is fixedly connected to one side of the screening box 5. The surface of the limiting block 13 is slidably connected to the inner cavity of the limiting groove 12. The setting of the limiting groove 12 and the limiting block 13 can limit the up and down movement of the screening box 5, and increase the stability and smoothness of the screening box 5 when screening the medicine particles by its own up and down movement.
[0032] Reference Figure 2 and Figure 4A reinforcing ring block 15 is fixedly connected to one side of the processing box 1. The inner cavity of the reinforcing ring block 15 is rotatably connected to the surface of the rotating rod 701. A reinforcing hollow block 16 is fixedly connected to the surface of the fixing plate 605. One side of the reinforcing hollow block 16 is fixedly connected to one side of the moving box 4. The reinforcing ring block 15 can increase the stability of the rotating rod 701 when rotating, and reduce the tilting and sliding of the rotating rod 701 after long-term use. The reinforcing hollow block 16 can increase the stability of the connection between the fixing plate 605 and the moving box 4 by utilizing its connection with the fixing plate 605 and the moving box 4, so that the connection between the fixing plate 605 and the moving box 4 is not prone to breakage.
[0033] Reference Figure 2 and Figure 6 A reinforcing plate 11 is fixedly connected to the inner cavity of the mounting box 2. The inner cavity of the reinforcing plate 11 is rotatably connected to the surfaces of the drive rod 6061 and the rotating rod 701. A rubber block 14 is movably bonded to the inner cavity of the limiting groove 12. The reinforcing plate 11 can simultaneously limit the drive rod 6061 and the rotating rod 701, increasing the stability of their rotation and reducing the possibility of the first bevel gear 6062 and the second bevel gear 6063 failing to mesh smoothly due to tilting or shaking of the drive rod 6061 or the rotating rod 701. The rubber block 14 can provide a certain buffering effect on the falling of the limiting block 13 and the screening box 5, reducing the possibility of damage to the moving box 4 caused by repeated falling of the screening box 5 due to its own weight.
[0034] Working Principle: When using this device, the operator adds the granules to be screened into the screening chamber 5 and places it inside the movable chamber 4. Then, the operator starts the dual-axis motor 3. During operation, the dual-axis motor 3 simultaneously drives the rotating disk 601 and the drive rod 6061 to rotate. As the rotating disk 601 rotates, it drives the mounting rod 604 and the fixed plate 605 connected to its bottom to reciprocate through the connection between the connecting plate 603, the connecting rod 602, and the mounting rod 604. This reciprocating motion moves the movable chamber 4 and the screening chamber 5, allowing the screening chamber 5 to move through the reciprocating mechanism. The system automatically sieves the drug particles. Simultaneously, the rotation of the drive rod 6061, through the meshing of the first bevel gear 6062 and the second bevel gear 6063, smoothly drives the rotating rod 701 and the cam 702 to rotate. The rotation of the cam 702 continuously and repeatedly pushes the rotating roller 705, thereby achieving up-and-down reciprocating vibration of the sieve box 5. This allows the sieve box 5 to vibrate up and down while reciprocating, making the sieve box 5 more effective in sieving drug particles. The sieved particles will be stored inside the sieve box 5, while the sieved impurities will fall into the processing box 1.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
