Technical Field

[0001] This utility model belongs to the technical field of single-screw granulators, specifically, it relates to a feeding mechanism and a single-screw granulator thereof. Background Technology

[0002] The main function of the feeding mechanism is to feed powdery or granular raw materials into the screw barrel of the single screw granulator at a set speed and amount to ensure the smooth progress of subsequent processing.

[0003] The prior art discloses a single-screw granulator (CN219543723U), including a base, a spiral extrusion channel mounted on the upper side of the base, a drive shaft and spiral extrusion blades rotatably mounted in the middle of the spiral extrusion channel, an extrusion port, a mounting groove and an extrusion template mounted at one end of the spiral extrusion channel, multiple mounting holes opened inside the extrusion template, a detachable die head installed in the mounting holes, and an extrusion die orifice opened inside the die head, the die head being provided with extrusion die orifices of various specifications. This utility model has a mounting groove and an extrusion template opened at one end of the extrusion port, and a detachable sealing end cap installed at one end of the extrusion port, so that the extrusion template can be disassembled and positioned by rotating and adjusting the sealing end cap. Moreover, the multiple mounting holes inside the extrusion template are equipped with detachable dies, and the dies have extrusion die orifices opened inside the dies, making it easy to disassemble individual extrusion die orifices, thereby facilitating the cleaning or replacement of individual die orifices and improving the flexibility of extrusion use.

[0004] Research revealed that existing feeding mechanisms cannot uniformly mix and process materials during use, resulting in uneven particle size at the feed hopper. Consequently, the granulated particles produced by the device are also uneven in size. Furthermore, the feed hopper cannot process the raw materials, which prevents it from assisting the granulator in its operation during the feeding process. This not only reduces the efficiency of granulation but also diminishes the practicality of the device.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments will be described clearly and completely below with reference to the drawings of the embodiments of the present application, and the following embodiments are used to illustrate the present application.

[0029] A feeding mechanism, such as Figure 1 ,Figure 2 and Figure 4 As shown, the system includes a feeding hopper 10, with a top plate 11 fixedly mounted on its top surface by bolts; and a processing structure rotatably disposed within the feeding hopper 10. The processing structure includes a conveying screw 14, a bottom scraper plate 16, a top scraper plate 17, a stirring screw 18, a shaft 19, and a grinding disc 20. The conveying screw 14, bottom scraper plate 16, top scraper plate 17, and grinding disc 20 are all fixedly disposed on the curved surface of the shaft 19. The stirring screw 18 is fixedly disposed between the bottom scraper plate 16 and the top scraper plate 17. The shaft 19 is rotatably disposed within the top plate 11. Figure 2 As shown, a feed pipe 12 for pouring materials is fixedly installed on the top surface of the top plate 11, and the feed pipe 12 is located at a position off-center from the center of the top plate 11; as Figure 1 and Figure 5 As shown, the feeding hopper 10 has a Y-shaped cylindrical structure. The inside of the feeding hopper 10 is provided with a frustum-shaped annular heating chamber 21. A spiral heating tube 22 is provided inside the heating chamber 21. A controller 13 is fixedly installed on the outer wall of the feeding hopper 10. The control end of the controller 13 is connected to the heating tube 22.

[0030] Specifically, this device, by setting up a heating tube 22 and a stirring auger 18, allows materials to be poured into the feeding hopper 10 through the feed pipe 12 during use. The controller 13 is then activated, controlling the heating of the heating tube 22 to start and stop. As the shaft 19 rotates, the stirring auger 18 mixes different materials in the feeding hopper 10. Simultaneously, when materials need to be heated, the stirring auger 18 helps prevent continuous contact between the materials and the heating tube 22 in the feeding hopper 10, thus helping to achieve uniform heating. In this way, the device can be used to granulate materials that need to be heated, as well as to granulate different mixtures. This not only improves the practicality of the device but also speeds up the granulation process to a certain extent.

[0031] like Figure 3 and Figure 4 As shown, a motor 15 is fixedly installed at the center of the top surface of the top plate 11. The output end of the motor 15 is connected to the top surface of the shaft column 19, which movably passes through the top plate 11. Figure 4 As shown, the bottom scraper plate 16 and the top scraper plate 17 have similar shapes but different orientations. Both the bottom scraper plate 16 and the top scraper plate 17 have an L-shaped structure and are symmetrically arranged on both sides of the shaft column 19. Both the bottom scraper plate 16 and the top scraper plate 17 correspond to the inner wall surface of the feed hopper 10; Figure 4 and Figure 5 As shown, the conveying screw 14 is fixedly mounted on the bottom curved surface of the shaft column 19, the bottom scraper plate 16 and the top scraper plate 17 are both fixedly mounted on the top curved surface of the shaft column 19, and the grinding disc 20 is fixedly mounted between the conveying screw 14 and the bottom scraper plate 16;Figure 4 As shown, the grinding disc 20 is a circular truncated block corresponding to the shape of the feeding hopper 10, the upper and lower edges of the grinding disc 20 are provided as arc surfaces, the stirring spiral strip 18 is arranged above the grinding disc 20, and the overall cross section of the stirring spiral strip 18 is similar to a cone.

[0032] Specifically, the center of the top plate 11 is provided with a bearing opening, a bearing is arranged in the bearing opening, and the top plate 11 is rotationally connected to the shaft column 19 through the bearing. In use, the motor 15 is started, the motor 15 controls the rotation of the shaft column 19, the shaft column 19 controls the bottom scraping wall plate 16 and the top scraping wall plate 17 to rotate and scrape the inner wall surface of the feeding hopper 10, at this time, the stirring spiral strip 18 stirs the materials and scrapes the materials attached in the feeding hopper 10. The device is provided with the grinding disc 20, the bottom scraping wall plate 16 and the top scraping wall plate 17, so that the materials sent out by the conveying spiral 14 are uniform in size and more delicate, thereby assisting the single-screw granulator body to granulate uniformly in size. The materials flow into the top arc surface of the grinding disc 20 through the wall surface of the bottom scraping wall plate 16 and the top scraping wall plate 17, and then flow into the position between the grinding disc 20 and the feeding hopper 10 and are ground more delicately, and then the materials are conveyed into the single-screw granulator body by the rotation of the conveying spiral 14.
