[0002] The size of pet food pellets directly affects palatability. Pellets that are too large may cause chewing difficulties or digestive problems, while pellets that are too small may cause respiratory problems. In pet food manufacturing, pelleting is necessary to improve digestion and absorption, enhance palatability, and optimize production efficiency.

[0003] Application No. 202420710810.5 discloses a pelletizing device for pet food production. By setting up a collection box, a drying plate, a heating rod, a heating plate and a transmission line, the device can transfer heat from the heating plate to the heating rod, and then from the heating rod to the drying plate, thereby drying the pet food on the drying plate.

[0004] The extruder head of the aforementioned application is located inside the device. When the extruder head is damaged or needs to be replaced with one of different orifice diameters, manual operation is inconvenient and affects work efficiency. In addition, food particles accumulate on the heating plate, which can easily lead to uneven heating. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please see Figures 1 to 4This utility model provides a technical solution: a pelletizing device for pet food production, including a pelletizing box 1, a pelletizing chamber 2 inside the pelletizing box 1, an extrusion mechanism 3 installed inside the pelletizing chamber 2, a feed inlet 21 inside the pelletizing box 1 and located at the top of the extrusion mechanism 3, a feed pipe 22 fixedly connected to the bottom of the feed inlet 21, one end of the feed pipe 22 being fixedly connected to the extrusion mechanism 3 to facilitate feeding materials into the extrusion mechanism 3, the extrusion mechanism 3 including an extrusion cylinder, a convex groove 4 inside the pelletizing box 1 and located at the top of the pelletizing chamber 2, two convex sliders 5 slidably connected inside the convex groove 4, and an extrusion head 6 fixedly connected to the bottom of each of the two convex sliders 5, one of the extrusion heads 6 being located at the discharge port of the extrusion mechanism 3 and attached to it. The two convex sliders 5 are fixedly connected. An electric push rod 15 is installed on the outer wall of the pelletizing box 1. The output end of the electric push rod 15 is fixedly connected to one of the convex sliders 5, pushing the convex slider 5 to move, so as to adjust the position of the two extrusion heads 6, so that the required extrusion head 6 is aligned with the extrusion mechanism 3, and it is convenient to replace the extrusion head 6. A support shaft 7 is rotatably connected inside the pelletizing chamber 2 and on one side of one of the extrusion heads 6. A cutter 8 is installed at one end of the support shaft 7 and fits against one of the extrusion heads 6. A motor 9 is installed on one side of the pelletizing box 1. The output end of the motor 9 is fixedly connected to the support shaft 7 through a coupling, driving the support shaft 7 to rotate, so that the cutter 8 cuts the extruded material and pelletizes it. The bottom of the pelletizing chamber 2 is provided with a spherical annular drying trough 10. A support plate 11 is rotatably connected inside the drying trough 10. Heating plates 12 are installed inside the pelletizing chamber 1 on both sides corresponding to the drying trough 10 to facilitate heating and drying of the material entering the drying trough 10. Guide plates 20 are installed on both sides corresponding to the pelletizing chamber 2 and at the bottom of the extrusion mechanism 3 and the support shaft 7 to facilitate guiding and buffering the falling particles. The support plate 11 is located on the center line of the drying trough 10, and both ends of the support plate 11 are in contact with the drying trough 10. The rotation axis of the support plate 11 is on the same horizontal axis as the center point of the drying trough 10, so that the support plate 11 can maintain contact with the drying trough 10 when rotating, preventing particles from falling. A base 13 is fixedly connected to the bottom of the pelletizing chamber 1. A hydraulic rod 14 is rotatably connected to the top of the base 13. One end of the hydraulic rod 14 is rotatably connected to the support plate 11, causing the support plate 11 to swing. This increases the shaking of the material, making it more evenly heated and dried. The angle of the support plate 11 can also be adjusted to extend it to the outside of the drying trough 10, allowing the material to be discharged. An air chamber 16 is provided inside the pelletizing box 1 and on one side of the pelletizing cavity 2. Multiple exhaust holes 17 are provided inside the pelletizing box 1 and between the pelletizing cavity 2 and the air chamber 16. A hot air blower 18 is installed on one side of the pelletizing box 1 and at the bottom of the motor 9. A filter screen and an air inlet pipe 19 are fixedly connected to the input and output ends of the hot air blower 18, respectively. One end of the air inlet pipe 19 is fixedly connected to the air chamber 16. Under the action of the hot air blower 18...Hot air is drawn into the air chamber 16 and then enters the pelletizing chamber 2 through multiple exhaust holes 17 to facilitate the drying of the falling pellets. A cold water tank 23 is installed on the top of the base 13 and on one side of the pelletizing chamber 1. A guide pipe 24 is fixedly connected between the cold water tank 23 and the pelletizing chamber 2. An exhaust pipe 25 and a drain pipe 26 are fixedly connected to one side of the cold water tank 23. The discharged hot air is guided into the cold water tank 23 through the guide pipe 24. The resistance of the water in the cold water tank 23 helps to reduce the discharge speed and temperature of the hot air before it is discharged through the exhaust pipe 25. A valve is installed on one side of the drain pipe 26. A control panel 27 is installed on one side of the pelletizing chamber 2 and on the top of the cold water tank 23.

[0019] In summary, in use, the electric push rod 15 drives one of the convex sliders 5 in the convex groove 4 to move. Since the two convex sliders 5 are fixedly connected, and extrusion heads 6 are installed at the bottom of both convex sliders 5, the positions of the two extrusion heads 6 can be adjusted so that the required extrusion head 6 is moved to the discharge port position of the extrusion cylinder in the extrusion mechanism 3. The material is then poured into the extrusion cylinder of the extrusion mechanism 3 through the feed port 21 and feed pipe 22. Under the action of the internal spiral conveying mechanism, it is pushed towards the extrusion head 6 and discharged through multiple extrusion holes in the extrusion head 6. At the same time, the motor 9 drives the support shaft 7 to rotate, causing multiple inclined cutters 8 at one end of the support shaft 7 to rotate accordingly, cutting the extruded material and performing pelleting. Simultaneously, the hot air blower 18 introduces the airflow heated by the heating element through the air inlet pipe 19 to the... Inside the air chamber 16, the air is then fed into the pelletizing chamber 2 through multiple exhaust holes 17 to dry the falling particles. When the pressure inside the pelletizing chamber 2 is too high, the airflow is guided into the cold water tank 23 through the air guide pipe 24 for cooling, and then discharged through the exhaust pipe 25. The two guide plates 20 inside the pelletizing chamber 2 guide the falling particles to enter the drying tank 10. The heating plate 12 heats and dries the drying tank 10 and the particles a second time. The hydraulic rod 14 drives the support plate 11 to swing repeatedly at the required angle, shaking the particles above it, and ensuring that the support plate 11 does not exceed the drying tank 10 during the swing, so that the particles do not fall out of the drying tank 10. After the drying is finished, the hydraulic rod 14 pushes the support plate 11 to tilt significantly, and one end of the support plate 11 extends to the outside of the drying tank 10, thereby opening the drying tank 10 and discharging the material.
