[0007] The granulation drive mechanism includes a motor, the output end of which is fixedly connected to a spline rod.

This achieves the production and processing of drug granules of different sizes. This design solves the problem of frequently changing the granulation cylinder when processing different drug granules, greatly improving the equipment's flexibility and production efficiency. Furthermore, by setting two conical obstruction rings inside the lower circular shell, the falling speed of the granular material can be slowed down.

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] Reference Figures 1 to 4 This application provides a high-quality drug granulation device, comprising: a feeding hopper 1, wherein the feeding hopper 1 is fixedly connected from top to bottom to an upper circular shell 2, a lower circular shell 3 and a hollow conical discharge cover 4, a hot air pipe 6 is fixedly sleeved at the center of the hollow conical discharge cover 4, a granulation cylinder 7 is fixedly installed inside the upper circular shell 2, two conical material blocking rings 31 are fixedly provided inside the lower circular shell 3, and a granulation drive mechanism 5 is installed between the feeding hopper 1 and the lower circular shell 3;

[0031] The granulation drive mechanism 5 includes a motor 51, the output end of which is fixedly connected to a splined rod 52. The splined rod 52 is driven by a spiral conveyor blade 54, a fan-shaped blade 57, an arc-shaped extrusion plate 58, a baffle plate 59, and a hollow spherical column 55, which are sequentially connected from top to bottom. The fan-shaped blade 57, the arc-shaped extrusion plate 58, and the baffle plate 59 are rotatably disposed inside the granulation cylinder 7, and the hollow spherical column 55 is rotatably disposed inside the lower cylindrical shell 3. The outer surface of the hollow spherical column 55 is fixedly sleeved with... There are two conical material-blocking rings 56 and multiple horizontal tubes 61. Multiple porous stirring tubes 611 are fixedly sleeved on the horizontal tubes 61. The conical material-blocking rings 31 and 56 are alternately arranged, and two horizontal tubes 61 are arranged between each of the conical material-blocking rings 31 and 56. The bottom end of the hollow spherical column 55 is rotatably sleeved with the hot air pipe 6. The device is connected by adding material into the feed hopper 1. The feed hopper 1 extends downward in sequence to form an upper circular shell 2, a lower circular shell 3, and finally a hollow structure. The conical discharge hood 4 forms a complete closed-loop system. The spline rod 52 is driven by the motor 51 to rotate, causing the spiral conveyor blade 54, fan-shaped blade 57, arc-shaped extrusion plate 58, baffle 59, and hollow ball column 55 to rotate. The height of the mounting plate 511 can be precisely adjusted by rotating the threaded rod 512, thereby changing the position of the baffle 59 in the granulation cylinder 7 and moving the arc-shaped extrusion plate 58 to different granulation hole positions, thus achieving the purpose of producing and processing drug granules of different sizes. This design solves the problem of frequently changing the granulation cylinder 7 when processing different drug granules, greatly improving the flexibility and production efficiency of the equipment. Furthermore, by setting conical material blocking ring 1 31 and conical material blocking ring 2 56 inside the lower circular shell 3, the falling speed of the granular material can be slowed down. By setting the hot air pipe 6 and the horizontal pipe 61 structure, the purpose of re-stirring and dispersing the granular material and uniformly drying it can be achieved, thus stabilizing product quality.

[0032] Reference Figure 1 and Figure 2 A feed pipe 11 is fixedly connected between the feed hopper 1 and the upper circular shell 2. The spiral conveyor blade 54 is rotatably installed inside the feed pipe 11. A horizontal plate 53 is rotatably connected to the upper end of the shaft of the spiral conveyor blade 54. The horizontal plate 53 is fixedly installed at the upper port of the feed hopper 1. The spiral conveyor blade 54 is installed inside the feed pipe 11, which can smoothly transport the loose material in the feed hopper 1 to the granulation cylinder 7. The shaft of the spiral conveyor blade 54 is rotatably connected to the horizontal plate 53, so that it rotates stably and achieves the purpose of continuous material conveying.

[0033] Reference Figure 1 and Figure 2 The motor 51 is fixedly connected to the mounting plate 511, and a threaded rod 512 is threadedly installed on the mounting plate 511. The bottom end of the threaded rod 512 is rotatably connected to the horizontal plate 53. The user can adjust the position of the motor 51 by rotating the threaded rod 512 according to actual needs, thereby changing the particle size processing production requirements.

[0034] ReferenceFigure 2 and Figure 4 The spline rod 52 is connected to the spiral conveyor blade 54 and the hollow ball column 55 by insertion. The fan-shaped blade 57, the arc-shaped extrusion plate 58 and the baffle 59 are fixedly sleeved on the spline rod 52. The arc-shaped extrusion plate 58 and the baffle 59 rotate and fit against the inner wall of the granulation cylinder 7. The rotational power of the spline rod 52 can simultaneously drive the spiral conveyor blade 54, the hollow ball column 55, the fan-shaped blade 57, the arc-shaped extrusion plate 58 and the baffle 59 to rotate. It is made of high-strength material, and by carefully setting the length ratio of each section, it ensures that each connection point can obtain appropriate torque transmission efficiency.

[0035] Reference Figure 1 and Figure 2 The granulation cylinder 7 has a conical structure at the top and its upper end is fixedly connected to the feed pipe 11. The granulation cylinder 7 is provided with multiple rings of granulation holes 1 71, granulation hole 2 72 and granulation hole 3 73 from top to bottom. The upper part of the granulation cylinder 7 has a conical contraction shape, which is conducive to guiding the material to slide naturally to the working area below. Three small holes of different diameters are regularly arranged on the cylinder body, namely granulation hole 1 71, granulation hole 2 72 and granulation hole 3 73. The size of these holes increases sequentially. The position of the arc extrusion plate 58 can be adjusted according to production needs to achieve different drug particle processing purposes.

[0036] Reference Figure 1 and Figure 2 The upper round shell 2 is provided with a transparent observation port 21. The presence of the transparent observation port 21 greatly facilitates daily operation and management. The operator can observe the position of the baffle 59, which makes it easy to adjust the position of the arc extrusion plate 58. Moreover, the operator can intuitively understand the internal operation without frequently opening the machine, and promptly detect abnormalities and take corresponding measures to correct them.

[0037] Working principle: Based on the required granulation size, rotating the threaded rod 512 causes the mounting plate 511 to drive the motor 51 and splined rod 52 downwards, causing the fan-shaped blades 57, the arc-shaped extrusion plate 58, and the baffle 59 to move along the granulation cylinder 7. The baffle 59 can be observed moving to the granulation hole 71, granulation hole 72, or granulation hole 73 of the granulation cylinder 7 through the transparent observation port 21. This utilizes the different aperture positions of the arc-shaped extrusion plate 58 in the granulation cylinder 7 to achieve the production and processing of different sized drug granules, solving the problem of frequently changing the granulation cylinder 7 when processing different drug granules. When the drug raw material is added to the feed hopper 1 and the motor 51 is started, it drives the splined rod 52 to rotate at high speed, causing the spiral conveyor blades 54 located in the feed pipe 11 to start working, pushing the raw material from the feed hopper 1 along the axial direction into the granulation cylinder 7. The fan-shaped blades 57 further disperse it, and then the arc-shaped extrusion plate 58... The extrusion plate 58 applies pressure to force the drug through the granulation zone of the granulation cylinder 7 with specific apertures, including three granulation apertures: granulation aperture 1 71, granulation aperture 2 72, and granulation aperture 3 73. This cuts the drug into particles of the required size, which fall from the granulation cylinder 7 between the upper shell 2 and the lower shell 3. The falling of the granules is slowed by alternating conical blocking rings 1 31 and 2 56. The hollow spherical column 55 rotates at high speed, causing the horizontal pipe 61, which is equipped with multiple porous stirring tubes 611, to rotate between the conical blocking rings 1 31 and 2 56, further stirring and dispersing the granules. The high-temperature airflow blown in from the hot air pipe 6 enters the hollow spherical column 55 and is conveyed by the porous stirring tubes 611 on the horizontal pipe 61, so that the granules are uniformly dried and heated to help remove excess moisture and produce fresh granules. Finally, the qualified granule drug product is discharged and collected through the hollow structure of the hollow conical discharge cover 4.
