Description

Technical Field

[0001] This utility model relates to the field of granulator technology, and in particular to a circulating pressing mechanism for a granulator. Background Technology

[0002] Initially used primarily in the feed industry, roller pellet mills have expanded their applications with continuous technological advancements. In the pharmaceutical industry, they are used to granulate drug powders for easy administration, coating, and storage. Publication number CN218689214U discloses a dry pellet mill, relating to the field of pelleting equipment technology. This utility model discloses a dry pellet mill, relating to the field of pelleting equipment technology, including a housing, and further comprising: moving wheels; a fixing mechanism; a feed inlet; a conveying mechanism; an extrusion mechanism; a connecting ring; a crushing blade; a limiting mechanism; a screen; a discharge outlet; and a pelletizing blade. This invention uses movable wheels to move the shell, a fixing mechanism to fix the shell, and a limiting mechanism to fix and limit the screen. Raw materials enter the shell through the feed inlet, are conveyed by a conveying mechanism, and are extruded into flakes by an extrusion mechanism. A third drive unit rotates a crushing blade to crush the flakes, and the crushed material falls into the screen. A fourth drive unit rotates a granulating blade to granulate the material. This solves the problems of existing technologies where the thickness of the extruded material cannot be adjusted, and where the use of gears for granulation results in a short extrusion time and poor extrusion effect. For substandard materials that do not meet the particle size requirements after dry granulation, manual collection and processing are necessary, affecting production efficiency and increasing the labor intensity of operators, which is detrimental to improving material utilization and production efficiency. Therefore, improvements are needed. Utility Model Content

The material screening tray 12 has a guide plate 13 fixedly installed on its surface to guide qualified forming materials for easy collection. The screening box 10 has a second discharge port 14 on its surface. The lower surface of the screening box 10 has a collection box 15 fixedly installed to store substandard materials and material powder. The side of the collection box 15 has a suction pipe 16 fixedly installed. One end of the suction pipe 16 is fixedly installed with a vacuum pump 17. The output end of the vacuum pump 17 is fixedly installed with an exhaust pipe 18, which is responsible for conveying the collected material powder to the discharge port 3. The surface of the pressure roller 4 is slidably connected to the scraper 5 to facilitate scraping off the material on the surface of the pressure roller 4. The guide plate 13 is fixedly installed between the surface screening box 10 and the material screening box 10. The guide plate 13 can effectively guide the material into the screening box 10 to ensure the smooth progress of the screening process. One end of the exhaust pipe 18 is fixedly installed between the discharge port 3 to facilitate the conveying of substandard materials and powdery materials to the discharge port 3 for further processing.

[0025] Example 2

[0026] Please see Figure 4-5 The inside of the discharge port 3 is rotatably connected to a movable plate 19, which facilitates the control of the discharge speed. A connecting block 20 is fixedly installed on the surface of the movable plate 19, and a rotating block 21 is rotatably connected to the inner surface of the connecting block 20, which allows the size of the discharge port 3 to be adjusted by rotating the movable plate 19. A fixing groove 22 is opened on the surface of the rotating block 21, and a fixing block 23 is fixedly installed on the surface of the discharge port 3 to support the rotating block 21. The connecting block 20 and the rotating block 21 are slidably connected to the discharge port 3, which facilitates more flexible adjustment of the movable plate 19. The surface of the fixing groove 22 is slidably connected to the fixing block 23, which flexibly fixes the movable plate 19, which facilitates precise adjustment under different working conditions.

[0027] Working principle: In the granulation process, the material is first poured into the feed inlet 3, and then enters the protective cover 2 below. It is formed by the extrusion of two pressure rollers 4. The scraper 5 is responsible for scraping off the material that does not fall naturally from the pressure rollers 4 and it falls into the screening tray 12 below through the first discharge port 6. The vibration of the vibrating motor 11 allows the qualified and unqualified materials and material powder to be screened out. The qualified formed material will move to the second discharge port 14 under the guidance of the guide plate 13 for subsequent collection, while the unqualified formed material and material powder will fall into the collection box 15. The collection box 15 is arc-shaped to facilitate the collection of materials. It is convenient to use the vacuum pump 17 to suck the material into the feeding port 3 through the cooperation of the suction pipe 16 and the exhaust pipe 18 for the next round of granulation until the standard is met. When it is necessary to adjust the size of the feeding port 3, you can hold the handle of the rotating block 21 and rotate it upward until the fixing groove 22 leaves the surface of the fixing block 23. Then, move the rotating block 21 outward a little to facilitate subsequent fixing. Finally, rotate the rotating block 21 to the required position to align the fixing groove 22 with the fixing block 23 to achieve the effect of fixing the movable plate 19.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
