[0002] A puffing pellet mill is a machine used to process puffed foods, such as rice, corn, soybeans, and wheat. Its primary operating principle is to convert mechanical energy into thermal energy, using the heat generated by the machine's rotation to cook the food. The most obvious characteristic of puffed food is its increased volume. During production, the puffing pellet mill is connected to a feeding mechanism, which is a feeder. Its primary function is to feed unprocessed material into the pellet mill.

[0003] The existing feeding mechanism is prone to material accumulation at the bottom, causing the material to stick inside the feeding mechanism, resulting in uneven particle size of the material after granulation.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] A feeding mechanism of an extruding granulator, combined with Figure 1 As shown, it includes a feeding bucket 1, a stirring mechanism 2, a scraping mechanism 3, a bulking mechanism 4, an air circulation mechanism 5, a feed hopper 6, a spring rod 7, a hinge 8, and a valve plate 9. The stirring mechanism 2 includes a stirring motor 21, a rotating shaft 22, and a stirring rod 23; the scraping mechanism 3 includes a connecting rod 31, a scraper 32, and a mounting rod 33; the bulking mechanism 4 includes a bulking motor 41, a bulking roller 42, and a bulking box 43; and the air circulation mechanism 5 includes a filter 51, a fan 52, and a vent pipe 53.

[0017] The feeding bucket 1 is cylindrical in top and conical in bottom. A stirring mechanism 2 is mounted on the top of the feeding bucket 1. This stirring mechanism 2 includes a stirring motor 21 positioned at the center of the top surface of the feeding bucket 1. The stirring motor 21 is positioned vertically downward, with its rotating shaft 22 located on the central axis of the feeding bucket 1. A plurality of stirring rods 23 are mounted evenly on the rotating shaft 22. The stirring rods are arranged horizontally, with the lowest stirring rod approximately equal to the distance between the mounting rods.

[0018] The lower portion of the feeding bucket 1 is provided with a scraping mechanism 3, which is connected to the stirring mechanism 2. Therefore, no additional power device is required, saving costs. The scraping mechanism 3 includes a connecting rod 31 connected to the stirring mechanism 2. The connecting rod 31 is connected to the bottom end of the rotating shaft 22 and is arranged vertically. The connecting rod 31 is provided with a plurality of mounting rods 33, and the other end of the mounting rod 33 is connected to a scraper 32. The scraper 32 is closely attached to the inner wall of the tapered portion of the feeding bucket 1, promptly scraping off material that is squeezed and stuck to the inclined inner wall. The scraper 32 is connected to a mounting rod at each end, and a mounting rod can also be connected to the middle of the scraper to increase the stability of the scraper.

[0019] The bottom of the feeding bucket 1 is the discharge port, where a dispersing mechanism 4 is located. This mechanism disperses the extruded and bonded material and crushes and disperses the material scraped from the inclined inner wall. Dispersing mechanism 4 includes a bulking box 43 connected to the discharge port of the feeding bucket 1. A horizontally mounted bulking roller 42 is hingedly mounted within this box. This roller 42 is equipped with several evenly spaced dispersing bumps and is connected to a bulking motor 41 mounted on the outer wall of the box 43.

[0020] The sidewall of the bulking mechanism 4 is connected to an air circulation mechanism 5, the other end of which is connected to the upper portion of the feeding bucket 1. The air circulation mechanism 5 includes a through-hole provided on the sidewall of the bulking box 43, on which a filter 51 is installed. This through-hole is connected to a vent pipe 53, the other end of which is connected to the middle portion of the feeding bucket 1 and is equipped with a fan 52.

[0021] A feed hopper 6 is provided on the top of the feeding barrel 1. A valve plate 9 is provided at the connection between the feed hopper 6 and the feeding barrel 1. The valve plate 9 is connected to the feeding barrel 1 via a hinge 8. A spring rod 7 is connected between the valve plate 9 and the feeding hopper 6. When feeding, the material presses the valve plate downward to open. When not feeding, the spring rod returns the valve plate to its original position to prevent heat in the feeding barrel from dissipating.

[0022] In actual use, the utility model enters the feeding barrel from the feed hopper, where the stirring device stirs the material. The material then enters the scraping mechanism, where the scraper promptly scrapes away the material on the inclined side wall of the feeding barrel. The material then enters the bulking mechanism along with other materials. The bulking roller disperses the adhered material, and the material is discharged from the bulking mechanism outlet and enters the puffing granulator for granulation. During use, the fan circulates the heat dissipated from the puffing granulator through the ventilation pipe to the feeding barrel, so that the heat circulates in the feeding barrel, reducing heat loss.
