Description

Technical Field

[0001] This invention relates to the field of granulation technology, specifically to an anti-clogging granulation device and granulation process for piglet feed processing. Background Technology

[0002] This anti-clogging pelleting equipment for piglet feed is an integrated molding and processing device adapted to the characteristics of piglet formula feed that is high in sugar and whey, highly viscous, and prone to sticking and clogging. Relying on the coordinated linkage of various functional structures such as feeding, conditioning, extrusion, pelleting, and cooling reflux, it avoids material sticking, bridging, and mold clogging and blockage problems from multiple dimensions such as material properties, feed flow rate, and discharge environment. It can continuously extrude pre-treated powder into piglet feed pellets of uniform specifications, and simultaneously complete pellet cooling and shaping and reprocessing of broken materials. The whole process achieves long-term anti-clogging and stable pelleting production.

[0003] "Whey powder, sucrose, glucose, and milk powder": If these ingredients make up more than 10% of piglet compound feed, it will be difficult to pellet, and they will not easily pass through the die holes of the pellet mill. Even if they do pass through, the pellets will be hard. Generally, high-grade piglet compound feed (creep feed) contains 15%-30% of the above four ingredients.

[0004] In existing anti-clogging pelleting equipment for piglet feed processing, after the material is shaped and cut, it is easy for the material to collide with the components during the falling process, resulting in pellet breakage and affecting the forming effect. Secondly, if the material is not cleaned in time during the extrusion process, it is easy to cause blockage inside the extrusion port.

[0014] This invention provides an anti-clogging pelleting device and pelleting process for piglet feed processing. It has the following beneficial effects: I. This anti-clogging pelleting equipment and pelleting process for piglet feed processing involves material falling from the top of the feeding trough and being fed into and out of the receiving shell through a discharge mechanism. The receiving shell is connected to the feeding trough and adopts a funnel shell structure to guide and collect the feeding material particles. Cold air generated by a compressor flows counter-currently upward from the bottom of the receiving shell through a connecting pipe, cooling the falling particles through contact heat exchange. The cold air carries away the heat and surface moisture of the particles, causing them to cool, shrink, and harden to complete their shaping. The exhaust gas carrying the humid heat is discharged from the top of the equipment, and the cooled and shaped particles are discharged from the bottom of the receiving shell. The perforated plate acts as a barrier to prevent particles from entering the pipe and thus ensuring smooth airflow.

[0015] II. The anti-clogging pelleting equipment and pelleting process for piglet feed processing uses a flexible material at the soft joint end for connection between the receiving shell and the limiting plate, thereby improving the flexibility of the components. When the pellets fall from the top of the receiving shell, the limiting plate supports them from both sides of the receiving shell, thereby limiting the material's descent speed and providing time for subsequent shaping. Secondly, when the material pellets hit the limiting plate, the limiting plate drives the support rod to slide to both sides of the receiving shell, causing the support rod to compress and contract the first spring, thereby playing a shock-absorbing and buffering role, reducing the impact force of the pellets falling, preventing the hot and soft piglet pellets from falling from a height and cracking into powder, improving the integrity rate of the finished product, slowing down the material's descent rate, extending the contact time with cold air, facilitating sufficient cooling and shaping, and reducing pellet adhesion.

[0016] III. The anti-clogging pelleting equipment and pelleting process for piglet feed processing utilizes a first motor to control the support shaft, which drives the discharge plate to rotate. By controlling the angle between the discharge plate and the bottom of the receiving shell, the opening and closing angle of the components is controlled, thereby controlling the material descent speed. This extends the contact time with cold air, allowing the pellets to dissipate heat and dehydrate fully, improving cooling and shaping efficiency, reducing pellet softening and sticking, and preventing material accumulation and blockage, as well as localized heat and moisture buildup. Additionally, plastic shells are installed on both sides of the discharge plate, with spherical blocks inside. These spherical blocks support the plastic shells, allowing them to engage with limiting blocks, further improving the sealing effect and preventing cold air leakage. Furthermore, the plastic material increases the wear resistance of the components, reducing wear and extending their service life. The limiting blocks restrict the deformation range of the plastic shells from both sides, improving the stability of the sealed components.

[0017] IV. The anti-clogging granulation equipment and granulation process for piglet feed processing: The material enters the extrusion shell from the top of the feed pipe and continuously accumulates inside the extrusion shell. The second motor controls the rotation of the extrusion support shaft, which drives the spiral blade to rotate, thereby conveying the material. The spiral blade pushes the material to one side of the extrusion groove. The opening of the extrusion groove is small. The spiral blade continuously pushes the material to squeeze and extrude it from one side of the extrusion groove. The material is squeezed and shaped through the extrusion groove, which facilitates subsequent shaping and granulation. The receiving block supports the extrusion support shaft, and the other side of the receiving block is connected to the cutting device to maintain the stability of the cutting device operation.

[0018] V. The anti-clogging pelleting equipment and pelleting process for piglet feed processing, during the cutting and pelleting operation, the sliding block drives the component to slide away from the center of the anti-clogging frame, so that the support plate is away from the center of the anti-clogging frame, avoiding affecting the component's cutting operation and preventing the component from colliding. When the equipment stops operating, some impurities remain inside the extrusion groove. The sliding block drives the support plate to align and close from both sides. The distance between the support plate and the extrusion groove is controlled by the first electric push rod, which facilitates subsequent cleaning of the component. The insertion rod is set on the support plate, and at the same time, the insertion rod is correspondingly set to the extrusion groove. The support plate drives the insertion rod to insert into the extrusion groove, thereby extruding the material and cleaning the groove, preventing the material from solidifying and clogging inside the groove, and preventing affecting the efficiency of subsequent operation of the component. After the operation is completed, the component moves to both sides or retracts. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] First embodiment, such as Figures 1 to 2 As shown, the present invention provides a technical solution: an anti-clogging pelleting device and pelleting process for piglet feed processing, comprising: Workbench 1 has a square block structure and fixed support legs at the bottom of the square block.

The bottom of the support base 2 is fixedly connected to the top of the worktable 1 away from the extrusion device 3. The top of the support base 2 is fixedly connected to the bottom of the cutting device 5. A feeding trough 4 is provided on the top of the worktable 1 near the center of the extrusion device 3 and the cutting device 5. A receiving device 6 is fixedly connected to the bottom of the worktable 1 near the feeding trough 4. The side of the extrusion device 3 opposite to the support base 2 is rotatably adapted to the cutting device 5. The extrusion device 3 pushes the material to move continuously to one side of the cutting device 5. The material is continuously squeezed by the screw conveyor, and the material is squeezed into strips and discharged. Then, the cutting device 5 divides the strip material, thereby playing a role in shaping and granulation. The granules cut off move from the feeding trough 4 to the receiving device 6. The receiving device 6 temporarily stores the material, which facilitates subsequent collection and processing.

[0023] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 2 to 6 As shown, the extrusion device 3 includes an extrusion housing 31, a support frame 39 fixedly connected to the outside of the extrusion housing 31, a second motor 33 fixedly connected to one side of the outside of the extrusion housing 31, an extrusion support shaft 34 rotatably connected to the center of the inner wall of the extrusion housing 31, a receiving block 37 rotatably connected to the end of the extrusion support shaft 34 away from the second motor 33, the output end of the second motor 33 fixedly connected to one end of the extrusion support shaft 34, an extrusion groove 36 is provided on the outside of the extrusion housing 31 near the receiving block 37, a spiral blade 35 is fixedly connected to the outside of the extrusion support shaft 34, a feed pipe 32 is fixedly connected to the outside of the extrusion housing 31 away from the support frame 39, and an anti-blocking mechanism 38 is fixedly connected to the outside of the extrusion housing 31 near the cutting device 5. Material enters the extrusion housing 31 from the top of the feed pipe 32. The material continuously accumulates inside the extrusion housing 31. The second motor 33 controls the rotation of the extrusion support shaft 34, which drives the spiral blade 35 to rotate, thereby conveying the material. The spiral blade 35 pushes the material towards one side of the extrusion groove 36. The opening of the extrusion groove 36 is relatively small. The spiral blade 35 continuously pushes the material, causing it to be squeezed and extruded from one side of the extrusion groove 36. The material is squeezed and shaped by the extrusion groove 36, which facilitates subsequent shaping and granulation. The receiving block 37 supports the extrusion support shaft 34. The other side of the receiving block 37 is connected to the cutting device 5 to maintain the stability of the cutting device 5 during operation.

[0024] The anti-blocking mechanism 38 includes an anti-blocking frame 381. A slide rail 382 is fixedly connected to the outside of the anti-blocking frame 381. A sliding block 383 is slidably connected to the inside of the slide rail 382. A connecting rod 384 is fixedly connected to the outside of the sliding block 383. A first electric push rod 385 is fixedly connected to the outside of the connecting rod 384 away from the sliding block 383. A support plate 386 is fixedly connected to the output end of the first electric push rod 385. An insert rod 387 is fixedly connected to the outside of the support plate 386. During the cutting and granulation operation, the sliding block 383 drives the component to slide away from the center of the anti-clogging frame 381, so that the support plate 386 is away from the center of the anti-clogging frame 381, avoiding affecting the component's cutting operation and preventing collisions. When the equipment stops operating, some impurities remain inside the extrusion groove 36. The sliding block 383 drives the support plate 386 to align and close from both sides. The distance between the support plate 386 and the extrusion groove 36 is controlled by the first electric push rod 385, which facilitates subsequent cleaning of the component. The insertion rod 387 is set on the support plate 386 and is correspondingly set to the groove of the extrusion groove 36. The support plate 386 drives the insertion rod 387 to insert into the extrusion groove 36, thereby extruding the material and cleaning the groove, preventing the material from solidifying and clogging inside the groove, and preventing it from affecting the efficiency of subsequent operations of the component. After the operation is completed, the component moves to both sides or retracts.

[0025] The cutting device 5 includes a mounting housing 51. A door panel 52 is hinged to one side of the mounting housing 51. A third motor 53 is fixedly connected to the inner wall of the mounting housing 51 away from the door panel 52. A cutting support shaft 54 ​​is rotatably connected inside the mounting housing 51 near the anti-blocking mechanism 38. The output end of the third motor 53 is fixedly connected to one side of the cutting support shaft 54. A cutting tool 55 is fixedly connected to the outer side of the cutting support shaft 54 ​​away from the third motor 53. The third motor 53 is located inside the mounting housing 51 and controls the rotation of the cutting support shaft 54. The cutting support shaft 54 ​​drives the cutting tool 55 to rotate, and the cutting tool 55 cuts the material extruded from the extrusion groove 36, thereby achieving the function of shaping and granulation.

[0026] The cutting tool 55 includes a second electric push rod 551. One end of the second electric push rod 551 is fixedly connected to a plug-in housing 552. A housing groove 556 is provided on the inner side of the plug-in housing 552. A connecting end 555 is plugged into the inner side of the housing groove 556. A cutting tool 554 is fixedly connected to the outer side of the connecting end 555. A buffer mechanism 553 is fixedly connected to the outer side of the cutting tool 554 near the plug-in housing 552. One side of the cutting tool 554 is rotatably connected to the receiving block 37. At the same time, the receiving block 37 supports the cutting tool 554. The second electric push rod 551 controls the insertion housing 552 to press and align with the cutting tool 554. This facilitates subsequent rotation and maintains the stability of the cutting tool 554 by pressing, avoiding affecting the rotation effect of subsequent components. In addition, it facilitates the disassembly of components and improves the convenience of component replacement or maintenance. The insertion housing 552 has a housing groove 556 inside. When the insertion housing 552 moves and aligns with the cutting tool 554, the housing groove 556 is inserted and aligned with the connecting end 555, thereby further improving the fitting effect and stability between components.

[0027] The buffer mechanism 553 includes a buffer base 5531, a guide rod 5532 fixedly connected to the inner side of the buffer base 5531, a third spring 5533 sleeved on the outer side of the guide rod 5532, a ring frame 5535 fixedly connected to the outer side of the buffer base 5531, and a buffer housing 5534 slidably connected to the outer side of the ring frame 5535. When the insertion housing 552 pushes the cutting tool 554 toward the receiving block 37, the component pressure causes the buffer housing 5534 to move appropriately toward the buffer base 5531, compressing and contracting the third spring 5533, thereby playing a role in shock absorption and buffering, thus reducing the vibration amplitude of the component and improving the stability of the component during operation. Secondly, the guide rod 5532 restricts the third spring 5533 to prevent the spring from shaking excessively. At the same time, the guide rod 5532 plays a limiting role to prevent the buffer housing 5534 from contracting excessively. In addition, the ring frame 5535 is set on the outside of the buffer base 5531 and slides on the inside of the buffer housing 5534, thereby increasing the connection effect between the components and preventing the components from derailing during sliding.

[0028] The cutting tool 554 includes a cutting housing 5541, a tool base 5542 fixedly connected to the outer circumference of the cutting housing 5541, and pressing rods 5543 slidably connected to both sides inside the tool base 5542. A pressing plate 5544 is fixedly connected to one side of the pressing rods 5543, and a tool block 5545 is inserted and detachably fitted onto the pressing plate 5544. The bottom of the tool block 5545 is inserted into the tool base 5542. The pressing rods 5543 push the pressing plate 5544 to press and clamp the tool block 5545 from both sides of the tool base 5542, thereby quickly fixing the component and maintaining its stability. This facilitates subsequent tool replacement and installation, and prevents the component from affecting its cutting performance after prolonged operation.

[0029] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 7 to 9 As shown, the receiving device 6 includes: The receiving shell 61 has a funnel shell structure, and the bottom of the receiving shell 61 is fixedly connected to the discharge mechanism 63. The compressor 64 has a square shell structure. The outer side of the compressor 64 is fixedly connected to the lower outer side of the receiving shell 61. A connecting pipe 65 is fixedly connected to one side of the compressor 64. The outer side of the connecting pipe 65 is fixedly connected to the outer side of the receiving shell 61. A perforated plate 66 is fixedly connected to the inner wall of the receiving shell 61 near the connecting pipe 65. Material falls from above the feeding trough 4 and is fed into and out of the receiving shell 61 by the discharge mechanism 63. The receiving shell 61 is connected to the feeding trough 4 and adopts a funnel shell structure to guide and collect the material particles. Cold air generated by the compressor 64 flows counter-currently upward from the bottom of the receiving shell 61 through the connecting pipe 65 to cool the falling particles. The cold air carries away the heat and surface moisture of the particles, causing them to cool down, shrink, and harden to complete the shaping. The exhaust gas carrying the humid heat is discharged from the top of the equipment. The cooled and shaped particles are discharged from the bottom of the receiving shell 61. The mesh plate 66 prevents particles from entering the pipe and avoids affecting the smooth flow of air.

[0030] The receiving device 6 also includes a flexible connector 62, which is disposed inside the receiving housing 61. One side of the flexible connector 62 is fixedly connected to the upper side of the inner wall of the receiving housing 61, and the other side of the flexible connector 62 is fixedly connected to a limiting plate 67. The support rod 68 has a cylindrical structure. One end of the support rod 68 is fixedly connected to the outside of the limiting plate 67, and the outside of the support rod 68 is slidably connected to the outside of the receiving shell 61. A first spring 69 is sleeved on the outside of the support rod 68 near the limiting plate 67. The flexible connector 62 is made of flexible material and is used to connect the receiving shell 61 and the limiting plate 67 to improve the flexibility of the component. When the particles fall from the top of the receiving shell 61, the limiting plate 67 supports them from both sides of the receiving shell 61 to limit the falling speed of the material and provide time for subsequent shaping. Secondly, when the material particles hit the limiting plate 67, the limiting plate 67 drives the support rod 68 to slide towards both sides of the receiving shell 61, so that the support rod 68 compresses and contracts the first spring 69, thereby playing a shock absorption and buffering role, reducing the impact force of the falling particles, preventing the hot and soft piglet particles from falling from a height and breaking into powder, improving the integrity rate of the finished product, slowing down the falling speed of the material, extending the contact time of the cold air, facilitating sufficient cooling and shaping, and reducing particle adhesion.

[0031] The discharge mechanism 63 includes a discharge frame 631, a support shaft 633 rotatably connected to the opposite side of the discharge frame 631, a first motor 632 fixedly connected to one side of the discharge frame 631, the output end of the first motor 632 fixedly connected to one end of the support shaft 633, a discharge plate 634 fixedly connected to the outside of the support shaft 633, plastic shells 637 fixedly connected to both sides of the outside of the discharge plate 634, a spherical block 636 is provided inside the plastic shell 637, a limit block 635 is plugged into the outside of the plastic shell 637, and the outer side of the limit block 635 is fixedly connected to the lower side of the inner wall of the receiving shell 61. The first motor 632 controls the support shaft 633 to drive the discharge plate 634 to rotate. By controlling the angle between the discharge plate 634 and the bottom of the receiving shell 61, the opening and closing angle of the component is controlled, thereby controlling the material descent speed. This extends the contact time with the cold air, allowing the particles to dissipate heat and dehydrate fully, improving cooling and shaping efficiency, reducing particle softening and sticking, and preventing material accumulation and blockage, as well as localized heat and moisture buildup. Plastic shells 637 are installed on both sides of the discharge plate 634, with spherical blocks 636 inside each shell. The spherical blocks 636 support the plastic shells 637, allowing them to engage with the limiting blocks 635, further improving the sealing effect and preventing cold air leakage. Furthermore, the plastic material increases the wear resistance of the component, reducing wear and extending its service life. The limiting blocks 635 restrict the plastic shells 637 from both sides, limiting their deformation range and improving the stability of the sealed component.

[0032] An anti-clogging pelleting process for piglet feed processing includes the following steps; S1, the material enters the extrusion shell 31 from the feed pipe 32, and the second motor 33 controls the extrusion support shaft 34 to drive the spiral blade 35 to rotate, pushing the material to be continuously squeezed and moved to one side of the extrusion groove 36, thereby achieving the function of extrusion discharge. S2, the third motor 53 controls the cutting support shaft 54 ​​to drive the cutting tool 55 to rotate, and the cutting tool 55 cuts the extruded material to achieve the granulation effect; S3, the material particles generated by cutting fall from the feed chute 4 at the top of the workbench 1, and the collecting device 6 is aligned with the feed chute 4 to collect the material. S4, the second electric push rod 551 of the cutting device 5 controls the retraction of the component, and inserts it into the hole of the extrusion groove 36 through the anti-clogging mechanism 38, thereby pushing the material inside the hole and preventing the material from clogging inside the hole after the operation is completed.

[0033] When in use, an extrusion device 3 and a cutting device 5 are installed on both sides of the top of the workbench 1. During operation, the cutting device 5 is connected to the extrusion device 3. The extrusion device 3 is equipped with a receiving block 37, and the receiving device 6 is equipped with a cutting blade 554. The receiving block 37 supports the cutting blade 554. The material enters the extrusion device 3 and is pushed towards the cutting device 5. The extrusion device 3 squeezes the material to shape and discharge it. Then, the cutting device 5 cuts the material to achieve granulation. The granules enter the receiving device 6 from the feeding trough 4 and are collected and shaped by the receiving device 6. The extrusion device 3 controls the rotation of the extrusion support shaft 34 through the second motor 33, which drives the spiral blade 35 to rotate. The spiral blade 35 pushes the material towards the extrusion groove 36, pushing the compressed material into the interior of the extrusion groove 36. The material is compressed and shaped by the extrusion groove 36, thereby achieving the function of discharging the material. The cutting device 5 controls the rotation of the cutting support shaft 54 ​​through the third motor 53. The cutting support shaft 54 ​​drives the cutting tool 55 to rotate, and the cutting tool 55 cuts the material, thereby playing the role of shaping and granulation. After the operation is completed, the anti-clogging mechanism 38 moves from both sides of the extrusion shell 31 toward the center. Then, the first electric push rod 385 controls the support plate 386 to drive the insertion rod 387 to insert into the hole of the extrusion groove 36, thereby pushing out the material inside the hole, preventing the material from solidifying inside the hole, preventing blockage of the hole, and preventing the part from being affected in terms of material output. When the cutting tool 554 needs to be replaced, the second electric push rod 551 controls the cutting tool 554 to move away from the receiving block 37, so as to facilitate the disassembly of the tool. Secondly, the material particles enter the inside of the receiving device 6. Compressors 64 are installed on both sides of the outside of the receiving shell 61. Air is sent into the receiving shell 61 through the compressors 64 to achieve counter-current air cooling, thereby enabling the particles to dissipate heat and dehydrate fully, improving the cooling and shaping efficiency, and reducing the softening and sticking of particles.

[0034] Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
