[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] This utility model embodiment provides a pelletizing mechanism for a pellet mill, such as... Figure 1-3 As shown, the device includes a ring mold 1, which comprises an annular mesh plate 11 and a first ring plate 12 and a second ring plate 13 coaxially mounted at both ends of the annular mesh plate 11. The first ring plate 12 is detachably connected to the base plate 2 via several first fixing components 3. A rotating shaft 4 is rotatably mounted on the base plate 2. An mounting plate 5 is mounted on one end of the rotating shaft 4 inside the ring mold 1. Pressure rollers 6 are rotatably mounted on both ends of the mounting plate 5. The sidewalls of the pressure rollers 6 abut against the inner wall of the annular mesh plate 11. The end of the rotating shaft 4 outside the ring mold 1 is connected to a driving device 7 for driving the rotating shaft 4 to rotate. Next, the driving device 7 is one of an electric motor, a hydraulic motor, or a pneumatic motor. The second ring plate 12 and the mounting plate 8 are detachably connected by several second fixing components 9. The mounting plate 8 is provided with a feeding hopper 81 on the side away from the ring die 1. The raw material can be poured into the ring die 1 through the feeding hopper 81. The driving device 7 can drive the rotating shaft 4 to rotate. The rotating shaft 4 can drive the mounting plate 5 to rotate. The mounting plate 5 can drive the pressure roller 6 to roll along the inner wall of the annular mesh plate 11 to squeeze the raw material, so that the raw material is squeezed out through the granulation holes on the side wall of the annular mesh plate 11 to form granules.

[0022] In this embodiment, as Figure 4-5As shown, mounting holes are provided on the first ring plate 12, the second ring plate 13, the base plate 2, and the mounting plate 8. The first fixing component 3 is fixed inside the mounting holes of the first ring plate 12 and the base plate 2, and the second fixing component 9 is fixed inside the mounting holes of the second ring plate 13 and the mounting plate 8. The first fixing component 3 and the second fixing component 9 have the same structure and both include a fixing block 31. The fixing block 31 is cylindrical and has a first mounting cavity 311 inside. Two connecting rods 32 are provided inside the fixing block 31 along its central axis. A limit block 33 is installed at one end of each connecting rod 32. Two first through holes 312 are provided on the side wall of the fixing block 31, and two limit blocks... Block 33 is movably disposed inside the two first through holes 312. A hand-held block 34 is installed at one end of the fixed block 31. The fixed block 31 and the hand-held block 34 are integrally formed and form a T-shaped structure. The hand-held block 34 has a second mounting cavity 341 that communicates with the first mounting cavity 311. The other ends of the two connecting rods 32 extend into the second mounting cavity 341 and are connected by an elastic element 35. The elastic element 35 is either a spring or a metal sheet. A button block 36 is also installed at one end of the two connecting rods 32 inside the second mounting cavity 341. The side wall of the hand-held block 34 has two second through holes 342. The two button blocks 36 are movably disposed inside the two second through holes 342.

[0023] When the ring mold 1 is installed on the base plate 2, the operator presses the button 36 on the first fixing component 3 to retract the limiting block 33 into the first mounting cavity 311. Then, the fixing block 31 is inserted into the mounting holes of the first ring plate 12 and the base plate 2. Finally, the button 36 is released, and under the elastic force of the elastic element 35, the limiting block 33 extends out from the first mounting cavity 311, fixing the limiting block 33 and the hand-held block 34 between the first ring plate 12 and the base plate 2. The operation is convenient. Similarly, the mounting plate 8 can be installed on the ring mold 1 in the same way, which makes it easy to assemble and disassemble the ring mold 1.

[0024] In this embodiment, as Figure 6-7As shown, two first arc-shaped protrusions 21 are evenly arranged on the edge of the mounting hole on the base plate 2 away from the first ring plate 12. After the first fixing component 3 is fixed on the first ring plate 12 and the base plate 2, rotating the hand block 34 causes both ends of the hand block 34 to press on the two first arc-shaped protrusions 21 respectively, which can make the base plate 2 and the first ring plate 12 more firmly fixed. Two second arc-shaped protrusions 82 are evenly arranged on the edge of the mounting hole on the mounting plate 8 away from the second ring plate 13. After the second fixing component 9 is fixed on the second ring plate 13 and the mounting plate 8, rotating the hand block 34 causes both ends of the hand block 34 to press on the two second arc-shaped protrusions 82 respectively. This makes the second ring plate 13 more securely fixed to the mounting plate 8. At the same time, one end of the first arc-shaped protrusion 21 and the second arc-shaped protrusion 82 is provided with a chamfer 211, which makes it easier for the hand block 34 to press on the first arc-shaped protrusion 21 or the second arc-shaped protrusion 82 when rotating the hand block 34. Meanwhile, the other end of the first arc-shaped protrusion 21 and the second arc-shaped protrusion 82 is provided with a stop block 212, which can restrict the hand block 34 on the first arc-shaped protrusion 21 or the second arc-shaped protrusion 82 after rotating the hand block 34 to press on the first arc-shaped protrusion 21 or the second arc-shaped protrusion 82, so as to facilitate rotating the hand block 34 to a suitable position.

[0025] Specific principle: When the ring mold 1 is installed on the base plate 2, the operator presses the button 36 on the first fixing component 3 to retract the limiting block 33 into the first mounting cavity 311. Then, the fixing block 31 is inserted into the mounting holes of the first ring plate 12 and the base plate 2. Then, the button 36 is released. Under the elastic force of the elastic element 35, the limiting block 33 extends out from the first mounting cavity 311, fixing the limiting block 33 and the hand-held block 34 between the first ring plate 12 and the base plate 2. Then, the hand-held block 34 is rotated so that both ends of the hand-held block 34 press against the two first arc-shaped protrusions 21, which makes the base plate 2 and the first ring plate 12 more firmly fixed. Similarly, the mounting plate 8 can be installed on the ring mold 1 in the same way. When the ring mold 1 is removed from the base plate 2 or the mounting plate 8 is removed from the ring mold 1, the operation is reversed.

[0026] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
