Description

Technical Field

[0001] This utility model relates to the field of granulator technology, specifically to an anti-sticking dry granulator. Background Technology

[0002] A dry granulator is a molding device that uses mechanical extrusion granulation technology to directly compress powdered materials into granules. Its core feature is that it does not require the addition of binders or solvents and achieves the conversion of powder into granules through physical pressure.

[0003] In traditional dry granulation processes, air inclusion and uneven density often exist in the material before it enters the granulation stage. The presence of air can lead to defects such as voids and uneven particle size during subsequent tableting and crushing processes, affecting the quality of the final product. Moreover, materials with uneven density are difficult to form into tablets of consistent thickness and stable quality during tableting, which in turn affects the particle size distribution of the crushed particles. Utility Model Content

[0004] The purpose of this invention is to provide an anti-sticking dry granulation machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-sticking dry granulator, comprising a shell, wherein a feed hopper is fixedly installed on the top of the shell, and further comprising: A mixing assembly installed on the feed hopper for mixing and stirring materials; a tableting assembly for tableting materials is installed inside the housing; and a box is fixedly installed on one side of the housing. A crushing component for shredding materials is installed inside the housing and below the tableting assembly, and a screening component for screening materials is installed below the crushing component.

[0006] Preferably, the stirring assembly includes a motor fixedly installed on the top of the feed hopper, a rotating shaft fixedly installed at the output end of the motor, and a stirring paddle fixedly installed on the outer side of the rotating shaft.

[0007] Preferably, the tablet pressing assembly includes two pressure rollers rotatably mounted inside the housing, each pressure roller having a gear fixedly mounted on it, and a motor mounted on one side of one of the pressure rollers.

[0008] Preferably, the output end of the second motor is fixedly connected to the gear via a connecting rod.

[0009] Preferably, the crushing component includes a rotating rod rotatably installed inside the housing, a blade fixedly mounted on the rotating rod, and pulleys fixedly mounted on both the connecting rod at the output end of the motor and the rotating rod.

[0010] Preferably, the screening assembly includes a sieve plate installed inside the housing, a spring fixedly installed at the bottom of the sieve plate, the bottom of the spring being fixedly connected to the inner wall of the housing via a support, and two symmetrical cams fixedly installed on the outer side of the rotating rod.

[0011] Preferably, a conical hopper is fixedly installed inside the housing, and a feed pipe is fixedly installed on the top of the feed hopper.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses a stirring assembly to force-push and degas the material, increasing material density and eliminating residual air to ensure uniform tableting. The tableting assembly uses two rollers to press synchronously, combined with gear transmission to achieve precise pressure control and reduce tablet thickness deviation. The crushing assembly shares a power source with the tableting assembly, and through belt pulley transmission, the high-speed rotation of the blades quickly cuts the tablets into particles. The screening assembly uses a cam for vibratory screening, with a rotating rod driving the cam to periodically lift the screen plate, and a spring to achieve high-frequency vibration while improving screening efficiency.

[0015] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-6 As shown, an anti-sticking dry granulator includes a shell 1, a feed hopper 2 fixedly installed on the top of the shell 1, and a solenoid valve (not shown) installed at the bottom of the feed hopper 2. It also includes: a stirring assembly 3 installed on the feed hopper 2 for mixing materials; a pressing assembly 5 installed inside the shell 1 for pressing materials into tablets; a box 4 fixedly installed on one side of the shell 1; a crushing assembly 6 installed inside the shell 1 and below the pressing assembly 5 for crushing materials; and a screening assembly 7 installed below the crushing assembly 6 for screening materials.

[0017] Material is fed into hopper 2 and stirred by agitator 3. Air is expelled, and the material is forced to move downwards, gradually increasing its density. This material is then forced into tableting assembly 5, which presses it into thin tablets. Simultaneously, the tablets are cut into desired particle sizes by a high-speed rotating crushing assembly 6. The resulting particles are then passed through screening assembly 7 and fed into a vibrating screen to obtain the desired particle size and density. This completes the entire granulation process.

[0018] Based on the above implementation scheme, the stirring assembly 3 includes a motor 31 fixedly installed on the top of the feed hopper 2, a rotating shaft 32 fixedly installed at the output end of the motor 31, and a stirring paddle 33 fixedly installed on the outside of the rotating shaft 32.

[0019] After the material enters the feed hopper 2, the motor 31 is turned on, which drives the rotating shaft 32 to rotate. The rotating shaft 32 drives the stirring paddle 33 on its outer side to stir the material. While removing air, the material gradually forms a forced push as it moves downward.

[0020] Based on the above implementation plan, and referring to Figure 4 The tablet pressing assembly 5 includes two pressure rollers 51 rotatably mounted inside the housing 1. Gears 52 are fixedly mounted on both pressure rollers 51. A second motor 53 is mounted on one side of one of the pressure rollers 51. The output end of the second motor 53 is fixedly connected to the gear 52 through a connecting rod. A connecting rod is fixedly mounted on the output end of the second motor 53, and the connecting rod is fixedly connected to one of the gears 52.

[0021] When the material is tableted, one of the pressure rollers 51 is driven to rotate by motor 53. The pressure roller 51 drives the other pressure roller 51 to rotate through two meshing gears 52. The material is tableted by the two pressure rollers 51.

[0022] Based on the above implementation scheme, the crushing component 6 includes a rotating rod 61 rotatably installed inside the housing 1, a blade 62 fixedly installed on the rotating rod 61, and pulleys 63 fixedly installed on the connecting rod at the output end of the motor 2 53 and the rotating rod 61; the two pulleys 63 are connected by a belt (not shown in the figure), and the pulleys 63 are selected with appropriate size.

[0023] The motor 53 drives the pulley 63 on its output end to rotate. The two pulleys 63 drive the rotating rod 61 to rotate. The rotating rod 61 drives the outer blade 62 to rotate, crushing the tableted material into granules.

[0024] Based on the above implementation scheme, the screening component 7 includes a sieve plate 71 installed inside the housing 1, a spring 72 fixedly installed at the bottom of the sieve plate 71, the bottom of the spring 72 being fixedly connected to the inner wall of the housing 1 through a support, and two symmetrical cams 73 fixedly installed on the outer side of the rotating rod 61.

[0025] When the rotating rod 61 rotates, it drives the two cams 73 on it to rotate. When the cams 73 rotate to contact the screen plate 71, the screen plate 71 vibrates up and down through the spring 72, thus screening the material on the screen plate 71.

[0026] Based on the above implementation scheme, a conical hopper 8 is fixedly installed inside the shell 1, and a feed pipe 9 is fixedly installed on the top of the feed hopper 2.

[0027] The conical hopper 8 conveys the mixed material between the two pressure rollers 51, and the feed pipe 9 is used to add material to the feed hopper 2.

[0028] It should be noted that in this solution, motor 1 (31), motor 2 (53), and solenoid valve are all electrically connected to the control terminal via wires. The control terminal can be set as a PLC programmable logic controller to control the above-mentioned electrical equipment to work. The above should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can adopt conventional choices in this field. This technical solution will not be further elaborated in detail.
