Description

Technical Field

[0001] This utility model relates to the field of pellet mill technology, and in particular to a feed production pellet mill. Background Technology

[0002] A granulator is a highly efficient piece of equipment that processes liquid, powdery, or lumpy materials into granules of a specific shape through processes such as heating, extrusion, and cutting. It is widely used in industries such as chemicals, plastics, food, pharmaceuticals, and fertilizers. Its core function is to shape materials into uniform granules through mechanical action (such as screw extrusion, roller rolling, and spray atomization) and thermal action (such as heating and melting or drying), thereby improving the material's flowability, storage properties, transportability, and subsequent processing performance. In feed production, granulation operations are often required.

[0003] To address this, the existing utility model patent with application number CN202022389059.8 proposes a feed production pelleting machine, which includes a box and a support at the bottom of the box. A feeding port is provided at the upper right side of the box, and a conical conveying roller is installed in the inner cavity of the box. A first motor is connected to the right side of the conveying roller through one end of the box. A storage box is also provided at the bottom of the shearing roller. Its structure is simple, the manufacturing and operating costs are low, and the production efficiency is greatly improved compared with the existing equipment.

[0004] While the pellet mill disclosed in the prior art possesses the aforementioned advantages, its use of multiple cutters to pulverize materials has revealed a problem in actual production: the cut feed tends to adhere to or accumulate in the gaps between adjacent cutters, preventing timely discharge and thus affecting the continuity and stability of subsequent pelleting operations. To address this technical problem, this invention provides an optimized and improved feed pellet mill. Utility Model Content

[0005] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a feed production pelleting machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A feed pellet mill includes a second servo motor, a housing, a feeding port, a conveying roller, and a discharge pipe. A mounting block is fixedly embedded inside the discharge pipe near its top. A storage groove is provided at the lower end of the mounting block. The top of the storage groove and the upper end of the mounting block are both semi-circular. Multiple feed outlets are evenly distributed at the top of the storage groove. A longitudinally arranged movable column is rotatably connected to the inner sidewall of the storage groove. A first servo motor is fixedly connected to the back of the discharge pipe. The output shaft of the first servo motor passes through the discharge pipe and the mounting block sequentially and is fixedly connected to the movable column. The output shaft of the first servo motor is rotatably connected to the discharge pipe and the mounting block. A second servo motor is fixedly embedded on the outer sidewall of the movable column. A plurality of ring-shaped cutters are fixedly connected, and a push block is provided between each cutter. A connecting rod is fixedly connected to the end of the push block facing the movable column. A spring is sleeved on the connecting rod, and the two ends of the spring are fixedly connected to the push block and the outer side wall of the movable column, respectively. A connecting groove is provided in the movable column. The end of the connecting rod away from the push block slides through the movable column and is fixedly connected to a connecting block. The connecting block is located in the connecting groove. A longitudinally arranged support rod is provided in the connecting groove near the center. A semi-circular stop block is fixedly connected to the lower end of the support rod. The end of the support rod away from the first servo motor passes through the movable column and is fixedly connected to the inner side wall of the storage slot. The support rod and the movable column are rotatably connected.

[0008] Preferably, a guide rod is fixedly connected to the side of the connecting block facing the connecting rod, and a sliding hole corresponding to the guide rod is provided on the inner side wall of the connecting groove, and the end of the guide rod away from the connecting block slides into the sliding hole.

[0009] Preferably, the lower end of the abutment block is provided with a groove, and a ball is rolled on the inner sidewall of the groove, with the lower end of the ball penetrating the groove.

[0010] Preferably, a support ring is rotatably sleeved on the support rod, and the side of the support ring away from the first servo motor is fixedly connected to the inner sidewall of the connecting groove.

[0011] Preferably, a rubber sleeve is fitted around the outside of the spring, and the two ends of the rubber sleeve are fixedly connected to the push block and the movable column, respectively.

[0012] Preferably, the thickness of the rubber sleeve is 1-3 mm.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention uses a first servo motor to drive a movable column to rotate the cutter, thereby cutting the extruded long strip of feed and completing the pelleting process. At the same time, an automatic cleaning mechanism composed of a support rod, a stop block, a connecting block, a connecting rod, a spring, and a push block can promptly remove feed particles from the gap between adjacent cutters, effectively preventing material accumulation and ensuring the continuity and stability of the pelleting operation.

[0015] This utility model uses a rubber cylinder to provide external protection for the spring, preventing feed residue from adhering and accumulating on the spring surface, ensuring the long-term stable operation of the spring. Furthermore, by setting ball bearings, the contact friction between the stop block and the connecting block is reduced, significantly improving the smoothness of the operation and service life of the moving part.

[0016] This invention can automatically clean feed particles from the gaps in the cutter blades, effectively preventing feed accumulation, ensuring continuous and stable operation of subsequent pelleting operations, and significantly improving the practicality and convenience of the equipment.

The specific structure and principle of the second servo motor, housing 1, feeding port, conveying roller, and discharge pipe 2 have been disclosed in the prior art and will not be repeated here.

[0024] In this embodiment, a mounting block 3 is fixedly embedded in the discharge pipe 2 near the top position for mounting the movable column 4. The lower end of the mounting block 3 is provided with a storage groove. The inner top of the storage groove and the upper end of the mounting block 3 are both semi-circular. Multiple feed outlets are evenly distributed in the top of the storage groove for extruding feed in strip form. The movable column 4 is rotatably connected to the inner side wall of the storage groove for driving the cutter 5 to rotate. A first servo motor 9 is fixedly connected to the back of the discharge pipe 2 for driving the movable column 4 to rotate. The end of the output shaft of the first servo motor 9 passes through the discharge pipe 2 and the mounting block 3 in sequence and is fixedly connected to the movable column 4. The output shaft of the first servo motor 9 is rotatably connected to the discharge pipe 2 and the mounting block 3.

[0025] In this embodiment, multiple annularly distributed cutters 5 are fixedly connected to the outer wall of the movable column 4 for cutting long strips of feed. A pusher block 6 is provided between each cutter 5 for cleaning up the feed particles accumulated between each cutter 5. A connecting rod 15 is fixedly connected to one end of the pusher block 6 facing the movable column 4 for driving the pusher block 6 to move. A spring 16 is sleeved on the connecting rod 15 for pulling the pusher block 6 to move and reset. The two ends of the spring 16 are fixedly connected to the pusher block 6 and the outer wall of the movable column 4, respectively. A rubber cylinder 7 is sleeved on the outside of the spring 16 for external protection of the spring 16. The two ends of the rubber cylinder 7 are fixedly connected to the pusher block 6 and the movable column 4, respectively. The thickness of the rubber cylinder 7 is 1-3 mm. The thinner thickness allows the rubber cylinder 7 to have good deformation ability.

[0026] In this embodiment, the movable column 4 is provided with a connecting groove. The end of the connecting rod 15 away from the push block 6 slides through the movable column 4 and is fixedly connected to the connecting block 13, which is used to drive the connecting rod 15 to move. The connecting block 13 is located in the connecting groove. The connecting rod 15 and the movable column 4 are slidably connected. The side of the connecting block 13 facing the connecting rod 15 is fixedly connected to the guide rod 14, which is used to guide the movement of the connecting block 13 in conjunction with the sliding hole. The inner side wall of the connecting groove is provided with a sliding hole corresponding to the guide rod 14. The end of the guide rod 14 away from the connecting block 13 slides into the sliding hole.

[0027] In this embodiment, a longitudinally arranged support rod 8 is provided in the connecting groove near the center position to support the abutment block 11 and the movable column 4. The lower end of the support rod 8 is fixedly connected to the semi-circular abutment block 11 to push the connecting block 13 downward. The lower end of the abutment block 11 is provided with a groove, and a ball bearing 12 is rolled on the inner side wall of the groove to reduce the friction between the abutment block 11 and the connecting block 13. The lower end of the ball bearing 12 passes through the groove. The end of the support rod 8 away from the first servo motor 9 passes through the movable column 4 and is fixedly connected to the inner side wall of the storage groove. The support rod 8 and the movable column 4 are rotatably connected. A support ring 10 is rotatably sleeved on the support rod 8 to support the support rod 8. The side of the support ring 10 away from the first servo motor 9 is fixedly connected to the inner side wall of the connecting groove.

[0028] In this embodiment, feed is first fed into the box 1 through the feeding port. The second servo motor is started to drive the conveying roller to transport the material in the box 1 to the discharge pipe 2. As the feed is continuously conveyed, the feed is extruded in strip form through the feed outlet. At the same time, the first servo motor 9 is started to drive the movable column 4 to rotate. The movable column 4 drives multiple cutters 5 to rotate synchronously, cutting the strip feed into granules. The cut feed granules are displaced as the movable column 4 rotates. When the feed moves to a position diagonally below or directly below the movable column 4, the feed granules fall naturally under the action of gravity and can be collected below the discharge pipe 2. Since some feed particles are prone to sticking or accumulating in the gaps between the cutters 5, when the movable column 4 rotates, it will synchronously drive the connecting block 13 to rotate and move. When the connecting block 13 passes under the abutment block 11, the semi-circular abutment block 11 will push the connecting block 13 down. The connecting block 13 drives the push block 6 down through the connecting rod 15, thereby pushing the feed particles to fall and preventing them from sticking and accumulating in the gaps between the cutters 5. After the connecting block 13 has completely passed the abutment block 11, the spring 16 pulls the push block 6 to reset and move through the elastic force.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
