Technical Field
[0001] This invention belongs to the technical field of feed extrusion equipment, and particularly relates to an extrusion feed extrusion unit. Background Technology
[0002] Extruded feed equipment can extrude powdered feed raw materials through high temperature and high pressure to form extruded feed with a certain shape and structure. It consists of a feeding system, an extrusion system, a heating and cooling system, a cutting system, and a control system. The principle is that the material enters the conditioner through the feeding system, where it is mixed with steam, water, etc. to improve the starch gelatinization degree and material plasticity. Then it enters the extrusion chamber. Under the push of the screw, the material moves forward and is squeezed and sheared. The temperature and pressure continuously increase. When the material passes through the die, the pressure drops sharply, the moisture evaporates rapidly, and the feed volume expands rapidly to form a porous structure.
[0003] When materials are expanded, they may clump or stick together, resulting in uneven material sizes. This requires workers to transport the clumps into a crusher for processing, which is quite troublesome. Additionally, because the material temperature is high after expansion, it needs to be cooled down before crushing, which consumes a lot of manpower and time, resulting in low efficiency. Summary of the Invention
[0004] To address the aforementioned problems, this invention proposes an extruded feed extrusion unit to more precisely resolve the problems described above.
[0005] This invention is achieved through the following technical solution: This invention proposes an extruded feed extrusion unit, including a base plate. An extrusion device, a cooling device, and a crushing device are installed on the upper surface of the base plate. The extrusion device is connected to the cooling device, and the cooling device is connected to the crushing device. A horizontal pipe is fixedly connected to one side of the extrusion device, and a circular cylinder is fixedly connected to one end of the horizontal pipe. The circular cylinder and the horizontal pipe are connected to the extrusion device. The cooling device is installed below the circular cylinder. A discharge pipe is fixedly connected to one side of the circular cylinder, and the discharge pipe is connected to the crushing device.
[0006] In one example, the cooling device includes a support frame, which is fixedly connected to a base plate. A circular shell is fixedly connected to the inner side of the support frame. Both the upper and lower surfaces of the circular shell are provided with through holes. A cooling fan is installed inside the circular shell. A circular cylinder is fixedly connected to the circular shell and communicates with the circular shell.
[0007] In one example, a first drive motor is fixedly connected to the upper surface of the cylinder, and a rotating rod is fixedly connected to the main shaft of the first drive motor. The rotating rod passes through the cylinder and is rotatably connected to the cylinder. A spiral conveyor plate is fixedly connected to the outer side of the rotating rod.
[0008] In one example, the crushing equipment includes a housing, which is fixedly connected to a discharge pipe and communicates with the discharge pipe. The upper surface of the housing is provided with a square through groove, in which a filter screen is fixedly connected. Two extrusion rollers are rotatably connected to the inner wall of the housing. A second drive motor is installed on one side of the housing, and the main shaft of the second drive motor is fixedly connected to one of the extrusion rollers. A first round rod is fixedly connected to the other side of each of the two extrusion rollers. The first round rod passes through the housing, and a gear is fixedly connected to one end of each first round rod. The two gears mesh.
[0009] In one example, the inner wall of the box is fixedly connected to two guide rods above the extrusion rollers, and a tapered tube is slidably connected to the two guide rods. A horizontal plate is fixedly connected to the inner wall of the tapered tube, and a flexible hose is fixedly connected between the horizontal plate and the discharge pipe. The flexible hose is provided with a vent hole and passes through the horizontal plate.
[0010] In one example, the inner wall of the housing is rotatably connected to a threaded rod that passes through the housing and through a tapered tube. The tapered tube is threadedly connected to the threaded rod. One end of the threaded rod is fixedly connected to a first circular plate. Multiple first actuating blocks are fixedly connected to the outer side of the first circular plate in a circular array. The first actuating blocks are arranged in a ring array. A second circular block is fixedly connected to one side of the two gears. Multiple second actuating blocks are fixedly connected to the outer side of the two second circular blocks in an arc array. The arc distribution area of the second actuating blocks is 90°.
[0011] In one example, a square through groove is provided on one side of the box, a circular rod is rotatably connected to the inner wall of the box, the circular rod passes through the box, a fixed frame is fixedly connected to the outer side of the circular rod, a vibrating screen is provided on the fixed frame, a support plate is fixedly connected to the inner side of the box, a rubber block is fixedly connected to one side of the fixed frame, and a discharge port is provided on one side of the box.
[0012] In one example, a servo motor is mounted on one side of the housing. The main shaft of the servo motor is fixedly connected to a circular rod. Two mounting blocks are fixedly connected to one side of the housing. A second circular rod is rotatably connected between the mounting blocks. A torsion spring is provided at the connection point. A rotating plate is fixedly connected to the outer side of the second circular rod. A vertical plate is fixedly connected to one end of the second circular rod. A push plate is fixedly connected to the outer side of the first circular rod.
[0013] The extruded feed extrusion unit proposed in this invention can bring the following beneficial effects: Firstly, by setting up cooling and crushing equipment, the feed is expanded by the extrusion equipment and then discharged into the horizontal pipe. The cooling equipment at the bottom of the cylinder cools the expanded feed. The cooled extruded material enters the crushing equipment through the discharge pipe, where larger materials are crushed, making the expanded material more uniform. Thus, when the material is discharged from the crushing equipment, the material temperature is suitable and the size is appropriate, so the staff can directly package it without transporting the material for processing, which is more convenient, faster, and saves time. Secondly, by setting up a spiral conveyor plate, the first drive motor drives the rotating rod to rotate, and the spiral conveyor plate rotates to transport the material upwards to the discharge pipe. At the same time, the cooling fan starts to generate an upward airflow, which further accelerates the upward movement of the material. The airflow and the spiral conveyor plate push the material upwards, avoiding the material being too heavy and causing it to accumulate at the bottom of the cylinder and not be able to approach the discharge pipe. Thirdly, by setting a rotating plate, when the material on the vibrating screen is discharged, the servo motor starts, driving the fixed frame to rotate and tilt. At the same time, the push plate on one side of the first round rod on the fixed frame rotates, pushing the vertical plate, causing the second round rod to rotate. The second round rod drives the rotating plate to rotate outward, opening the square through slot, which facilitates the material to slide out. When the discharge is completed, the servo motor reverses, the fixed frame resets, and the rotating plate resets under the action of the torsion spring, blocking the square through slot and preventing the material from being vibrated out.

[0023] To more clearly illustrate the overall concept of the present invention, a detailed description will be provided below with reference to the accompanying drawings and examples.
[0024] like Figures 1 to 7 As shown in the figure, an embodiment of the present invention proposes an extruded feed extrusion unit, including a base plate 1. An extrusion device 2, a cooling device 3, and a crushing device 4 are installed on the upper surface of the base plate 1. The extrusion device 2 is connected to the cooling device 3, and the cooling device 3 is connected to the crushing device 4. A horizontal pipe 5 is fixedly connected to one side of the extrusion device 2, and a circular cylinder 6 is fixedly connected to one end of the horizontal pipe 5. The circular cylinder 6, the horizontal pipe 5, and the extrusion device 2 are connected. The cooling device 3 is installed below the circular cylinder 6, and a discharge pipe 7 is fixedly connected to one side of the circular cylinder 6. The discharge pipe 7 is connected to the crushing device 4. After the feed is extruded by the extrusion device 2, it is discharged into the horizontal pipe 5 and then into the circular cylinder 6. At this time, the cooling device 3 at the bottom of the circular cylinder 6 cools the extruded feed. The cooled extruded material enters the crushing device 4 through the discharge pipe 7, crushing larger materials and making the extruded material more uniform. Thus, when the material is discharged from the crushing device 4, the material temperature is suitable and the size is appropriate. The staff can directly package it without transporting the material for processing, which is more convenient, faster, and saves time.
[0025] like Figure 1 and Figure 2As shown, the cooling device 3 includes a support frame 31, which is fixedly connected to the base plate 1. A circular shell 32 is fixedly connected to the inner side of the support frame 31. Both the upper and lower surfaces of the circular shell 32 are provided with through holes. A cooling fan 33 is installed inside the circular shell 32. A circular cylinder 6 is fixedly connected to the circular shell 32 and the circular cylinder 6 communicates with the circular shell 32. After the material enters the circular cylinder 6, the cooling fan 33 starts and generates an upward airflow to blow and cool the puffed material. At the same time, the upward airflow blows the puffed material to move towards the discharge pipe 7 with the airflow. The material enters the crushing device 4 through the discharge pipe 7. By using air cooling to dissipate heat, the puffed material can be cooled while the material can be accelerated to approach the discharge pipe 7, thus speeding up the processing speed of the puffed material.
[0026] like Figure 1 and Figure 2 As shown, a first drive motor 8 is fixedly connected to the upper surface of the cylindrical cylinder 6. The main shaft of the first drive motor 8 is fixedly connected to a rotating rod 9. The rotating rod 9 passes through the cylindrical cylinder 6 and is rotatably connected to the cylindrical cylinder 6. A spiral conveyor plate 10 is fixedly connected to the outer side of the rotating rod 9. After the material enters the cylindrical cylinder 6, the first drive motor 8 drives the rotating rod 9 to rotate, and the spiral conveyor plate 10 rotates, transporting the material upwards towards the discharge pipe 7. At the same time, the cooling fan 33 starts, generating an upward airflow, which further accelerates the upward movement of the material. The airflow and the spiral conveyor plate 10 push the material upwards, preventing the material from being too heavy and causing it to accumulate at the bottom of the cylindrical cylinder 6, making it unable to approach the discharge pipe 7.
[0027] like Figure 3 As shown, the crushing equipment 4 includes a housing 41, which is fixedly connected to a discharge pipe 7. The housing 41 communicates with the discharge pipe 7. A square through groove is provided on the upper surface of the housing 41, and a filter screen is fixedly connected in the square through groove. Two extrusion rollers 42 are rotatably connected to the inner wall of the housing 41. A second drive motor 43 is installed on one side of the housing 41. The main shaft of the second drive motor 43 is fixedly connected to one of the extrusion rollers 42. A first round rod is fixedly connected to the other side of each of the two extrusion rollers 42. The first round rod passes through the housing 41, and a gear 44 is fixedly connected to one end of each first round rod. The two gears 44 mesh, and the airflow pushes the material through the discharge pipe 7 into the housing 41, where it falls between the two extrusion rollers 42. The second drive motor 43 drives one of the extrusion rollers 42 to rotate. The two extrusion rollers 42 rotate synchronously through the two gears 44, crushing the material falling between the extrusion rollers 42 and preventing the agglomeration of the expanded material.
[0028] like Figure 4 and Figure 5As shown, two guide rods 11 are fixedly connected to the inner wall of the box 41 above the extrusion roller 42. A tapered tube 12 is slidably connected to the two guide rods 11. A horizontal plate 13 is fixedly connected to the inner wall of the tapered tube 12. A flexible hose 14 is fixedly connected between the horizontal plate 13 and the discharge pipe 7. The flexible hose 14 is provided with a vent hole. The flexible hose 14 passes through the horizontal plate 13. Part of the airflow is discharged through the vent hole on the flexible hose 14, and another part of the airflow is discharged through the bottom of the flexible hose 14. At the same time, the material is blown into the tapered tube 12 and then falls between the two extrusion rollers 42. The tapered tube 12 can move on the guide rods 11 and constantly change its position to avoid the material from accumulating in the tapered tube 12. At the same time, the airflow is discharged from one end of the flexible hose 14 in a downward direction, which can accelerate the speed at which the material falls between the extrusion rollers 42.
[0029] like Figure 4 and Figure 5 As shown, a threaded rod 15 is rotatably connected to the inner wall of the housing 41. The threaded rod 15 passes through the housing 41 and through a tapered tube 12. The tapered tube 12 is threadedly connected to the threaded rod 15. One end of the threaded rod 15 is fixedly connected to a first circular plate 16. Multiple first actuating blocks 17 are fixedly connected to the outer side of the first circular plate 16. The first actuating blocks 17 are arranged in a ring array. A second circular block 18 is fixedly connected to one side of the two gears 44. Multiple second actuating blocks 19 are fixedly connected to the outer side of the two second circular blocks 18. The second actuating blocks 19 are arranged in an arc array. The arc distribution area of the second actuating blocks 19 is 90°. The distribution area of the first actuating blocks 17 is the entire ring, while the distribution area of the second actuating blocks 19 only occupies one-quarter of the side of the second circular block 18. Each of the second actuating blocks 19 can interact with the first actuating blocks 18. When the extrusion roller 42 rotates, the two second circular blocks 18 rotate in different directions. The second actuating block 19 on one of the second circular blocks 18 first contacts the first actuating block 17, causing the first circular plate 16 to rotate clockwise, which in turn causes the threaded rod 15 to rotate, causing the tapered tube 12 to move and distribute the material to the center of the extrusion roller 42. After the first actuating block 17 disengages from the second actuating block 19 on the second circular block 18, the second actuating block 19 on the other second circular plate contacts the first actuating block 17. Since the two second circular blocks 18 rotate in opposite directions, the second actuating block 19 pushes the first circular plate 16 to rotate in reverse, and the tapered tube 12 moves in the opposite direction to distribute the material. In this way, when the extrusion roller 42 starts to extrude the material, the tapered tube 12 can be controlled to move back and forth to distribute the material and prevent the material from accumulating in the same position.
[0030] like Figure 6 and Figure 7As shown, a square through-slot is provided on one side of the box body 41. A circular rod 20 is rotatably connected to the inner wall of the box body 41, and the circular rod 20 passes through the box body 41. A fixed frame 21 is fixedly connected to the outer side of the circular rod 20. A vibrating screen 22 is provided on the fixed frame 21. A support plate 23 is fixedly connected to the inner side of the box body 41. A rubber block 24 is fixedly connected to one side of the fixed frame 21. A discharge port is provided on one side of the box body 41. After the material is crushed by the extrusion roller 42, it passes through the extrusion roller 42 and falls onto the vibrating screen 22 for screening. Material fragments fall through the vibrating screen 22. Materials that meet the requirements gather on the vibrating screen 22. After a period of time, the fixed frame 21 is rotated and tilted. Materials that meet the requirements slide down the tilted fixed frame 21, pass through the square through-slot, and are discharged from the box body 41 for collection. Smaller material fragments are discharged through the discharge port. By setting up the vibrating screen 22, the material is screened according to the particle size of the puffed material, which facilitates the grading and packaging of the material.
[0031] like Figure 6 and Figure 7 As shown, a servo motor 25 is installed on one side of the housing 41. The main shaft of the servo motor 25 is fixedly connected to a circular rod 20. Two mounting blocks 26 are fixedly connected to one side of the housing 41. A second circular rod 27 is rotatably connected between the mounting blocks 26. A torsion spring is provided at the connection point. A rotating plate 28 is fixedly connected to the outer side of the second circular rod 27. A vertical plate 29 is fixedly connected to one end of the second circular rod 27. A push plate 30 is fixedly connected to the outer side of the first circular rod. When the fixed frame 21 is horizontal inside the housing 41, the rotating plate 28 remains vertical under the action of the torsion spring. When material is discharged from the vibrating screen 22, the servo motor 25 starts, driving the fixed frame 21 to rotate and tilt. At the same time, the push plate 30 on one side of the first round rod on the fixed frame 21 rotates, pushing the vertical plate 29, causing the second round rod 27 to rotate. The second round rod 27 drives the rotating plate 28 to rotate outward, opening the square passage and facilitating the material to slide out. After the material is discharged, the servo motor 25 reverses, the fixed frame 21 resets, and the rotating plate 28 resets under the action of the torsion spring, blocking the square passage and preventing the material from being vibrated out.
[0032] Working principle: After being expanded by the extrusion equipment 2, the feed is discharged into the horizontal pipe 5 and then into the circular cylinder 6. The cooling fan 33 is started, generating an upward airflow to blow and cool the extruded material. At the same time, the upward airflow blows the extruded material towards the discharge pipe 7. The first drive motor 8 drives the rotating rod 9 to rotate, and the screw conveyor plate 10 rotates, transporting the material upward towards the discharge pipe 7. Part of the airflow is discharged through the through hole on the hose 14, and the other part is discharged through the bottom of the hose 14. At the same time, the material is blown into the conical tube 12 and then falls between the two extrusion rollers 42. The second drive motor 43 drives the extrusion rollers 42 to rotate and crush the material. The two second circular blocks 18 rotate in different directions. The second actuating block 19 on one of the second circular blocks 18 first contacts the first actuating block 17, causing the first circular plate 16 to rotate clockwise, which in turn causes the threaded rod 15 to rotate, causing the conical tube 12 to move towards the extrusion pipe 7. Material is distributed in the middle of the pressure roller 42. After the first actuating block 17 disengages from the second actuating block 19 on the second circular block 18, the second actuating block 19 on the other second circular plate contacts the first actuating block 17. The two second circular blocks 18 rotate in opposite directions. At this time, the second actuating block 19 pushes the first circular plate 16 to reverse, and the conical tube 12 moves in the opposite direction to distribute the material. After the material is crushed by the pressure roller 42, it passes through the pressure roller 42 and falls onto the vibrating screen 22 for screening. The material fragments fall through the vibrating screen 22, and the qualified materials gather on the vibrating screen 22. The servo motor 25 starts and drives the fixed frame 21 to rotate and tilt. At the same time, the push plate 30 on one side of the first round rod on the fixed frame 21 rotates and pushes the vertical plate 29, causing the second round rod 27 to rotate. The second round rod 27 drives the rotating plate 28 to rotate outward, opening the square through groove to facilitate the material to slide out, while smaller material fragments are discharged through the discharge port.
