Description

Technical Field

[0001] This invention relates to the field of material mixing and processing, specifically to a processing device for the internal void structure of pet granular food. Background Technology

[0002] There are many types of pet food, such as pet kibble, chew sticks, and pet treats. Apart from treats like jerky and meat bones, other pet foods are made by crushing and mixing various ingredients, then pelleting and drying them. These food pellets are dense and hard, making them difficult for puppies or senior pets to chew. Furthermore, felines and canines typically swallow food whole, which can cause puppies or senior pets to vomit due to indigestion. Soaking the food pellets in milk or water to soften them before feeding them doesn't provide the necessary teeth-grinding benefits.

[0003] The existing technology typically increases the porosity of pet food by improving the uniformity of material mixing, i.e., increasing the mixing time. This prolonged mixing incorporates air into the material. When the mixture is expelled during pelleting, the resulting food has internal pores, increasing its crispness and making it easier for pets to digest. However, this method of increasing porosity by extending mixing time is uncontrollable. The number of pores in the final pellets, or the proportion of pores within the pellet's internal space, is unpredictable, making it impossible to guarantee that the crispness of pet food pellets from the same batch is consistent. Summary of the Invention

[0004] The purpose of this invention is to provide a processing device for the internal void structure of pet granular food, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a processing device for the internal void structure of pet granular food, comprising: a machine base, a vertical mixing extruder fixedly mounted on the top of the machine base, and a plurality of extrusion nozzles equidistantly distributed in a straight line fixedly mounted on the side wall of the machine base, the plurality of extrusion nozzles being interconnected with the vertical mixing extruder, and the vertical mixing extruder being used to quantitatively extrude mixed pet food raw materials through the plurality of extrusion nozzles. The vertical mixing extruder is a commonly used device in the prior art, capable of mixing multiple food raw materials to form a paste, and then quantitatively extruding the paste through the extrusion nozzles;

[0006] It also includes: a receiving unit for receiving pet food mixture raw materials extruded quantitatively from a plurality of the extrusion nozzles, the receiving unit being located below the extrusion nozzles;

[0007] A pore-forming unit is used to create pores in the pet food mixture in the receiving unit, and the pore-forming unit is located inside the receiving unit.

[0008] Preferably, the receiving unit includes a fixed slide distributed at the bottom of the machine base, and the fixed slide is fixed in position relative to the machine base. A frame is slidably fitted onto the outside of the fixed slide, the frame is located directly below the extrusion nozzle, and the fixed slide is located to one side of the frame. The end face of the frame away from the fixed slide is open, and a positioning shaft is rotatably mounted on the open end face of the frame. Several forming plates are arranged in parallel inside the frame, and the end of each forming plate away from the fixed slide is fixedly fitted onto the positioning shaft. Externally, each of the molding plates has a support plate placed below the end away from the positioning axis, and the support plate is fixedly assembled with the sleeve frame. The top surface of the molding plate has several molding cavities arranged in a matrix. The molding cavities are used to receive pet food mixture raw materials extruded quantitatively by the extrusion nozzles. The sleeve frame can slide on the fixed slide frame. It can be driven to slide on the fixed slide frame by the cooperation of the electric motor, threaded rod and threaded slider in the prior art, so as to realize the addition of mixture raw materials into each molding cavity by several extrusion nozzles.

[0009] Preferably, the pore-forming unit includes several receiving cavities formed inside the molding plate. Each receiving cavity is located between two adjacent molding cavities that are distributed laterally. Inside each molding cavity, two symmetrically distributed docking rods are slidably assembled. The end faces of the two docking rods that are far apart from each other are fixedly provided with sliding shafts that are slidably embedded inside the molding cavity. The end faces of the two docking rods that are close to each other are fixedly provided with first racks, and the two first racks are distributed vertically and alternately. The molding plate is equipped with a rotating shaft that rotates longitudinally inside. The outer surface of the rotating shaft is fixedly fitted with a first gear that meshes with the two first racks. Each molding plate is provided with an actuating component and an ejecting component at the end near the fixed slide. Since the sliding shafts are embedded inside the molding cavity, when the mixed raw material is added into the molding cavity, the mixed raw material will wrap around the ends of several sliding shafts.

[0010] Preferably, the actuating component includes a limiting frame that is slidably mounted on the end face of the molding plate near the fixed slide. A second rack is slidably embedded inside the molding plate, and the second rack is perpendicular to the rotating shaft. A second gear that meshes with the second rack is fixedly fitted on the outer surface of each rotating shaft. A connecting rod that is perpendicularly distributed is fixedly provided on the end face of the second rack away from the positioning shaft. A stepped groove with a hollow shape is opened on the outer wall of the limiting frame, and the connecting rod slides through the stepped groove. A connecting piece is fixedly provided on the end face of the molding plate near the fixed slide, and a first spring is fixedly provided between the top of the connecting piece and the limiting frame. A limiting component is also provided on the top of the limiting frame. The steps of the stepped groove are inclined. When the limiting frame moves downward, the second rack can be pushed by the engagement of the connecting rod with the stepped groove.

[0011] Preferably, the limiting component includes a rotating column rotatably mounted on the top of the limiting frame, and a limiting piece is fixedly sleeved on the lower outer surface of the rotating column. Each molded plate has a handle fixedly installed on its upper surface. The handle is located on the side of the molded plate near the limiting frame and is used to lift and swing the molded plate. The side wall of the handle near the limiting frame has an axially distributed annular groove, which limits the limiting piece. The handle makes it easy for workers to flip the entire structure on the molded plate. Moreover, through the action of the annular groove, when the limiting frame is pressed by the rotating column, the limiting piece is locked in the position of the annular groove by the deflection of the rotating column, which can prevent the limiting frame from automatically resetting.

[0012] Preferably, the ejector component includes a tray slidably fitted inside each of the molding cavities. Movable plates are distributed directly below the molding plate, and connecting posts are fixedly arranged between several trays and the movable plates. The connecting posts slidably pass through the molding plate. Four pins arranged in a matrix are fixedly arranged at the bottom of the molding plate, and the pins slidably pass through the movable plates. A retaining ring is fixedly arranged on the end face of each pin away from the molding plate, and a tension spring is fixedly arranged between the end of the retaining ring near the molding plate and the movable plate. A knocking rod is rotatably suspended from the lower end face of the molding plate. The striking rods are distributed on the side of the molding plate near the fixed slide. A connecting rod is fixedly installed on the lower end face of the movable plate, and the connecting rod is also located on the side of the movable plate near the fixed slide. The two ends of the striking rod are directly below the limiting frame and the connecting rod, respectively. The bottom of the limiting frame is arc-shaped. When the limiting frame moves downward, after several sets of sliding shafts exit from the inside of the molding cavity, the continued downward movement of the limiting frame can press the striking rod, and push the connecting rod and the movable plate upward through the other end of the striking rod. The movable plate can then push several trays upward through the connecting column.

[0013] Preferably, a vibration component is further provided between each of the molding plates and the sleeve frame. The vibration component includes a retainer located below each of the movable plates. Each retainer is fixed to the sleeve frame. A first rotating shaft is rotatably arranged inside each retainer. A turntable is fixedly fitted onto the end face of the first rotating shaft near the molding plate. A top column is fixedly arranged at the center of the end face of the movable plate away from the molding plate. A plurality of arc-shaped right-angled trapezoidal blocks are fixedly arranged on the end face of the turntable near the molding plate. The arc-shaped right-angled trapezoidal blocks push the top column. A second rotating shaft is rotatably mounted on the side wall of the sleeve frame. The second rotating shaft and the first rotating shaft are connected by a synchronous gear belt. A rubber wheel is fixedly fitted on the outer surface of the second rotating shaft. The rubber wheel extends movably out of the sleeve frame and contacts the fixed slide. The rubber wheel and the side wall of the fixed slide frame are in compression contact. That is, when the sleeve frame slides on the fixed slide frame, the rubber wheel can roll due to friction.

[0014] Preferably, the length of the top column is less than the height of the arc-shaped right-angled step block, that is, after the arc-shaped right-angled step block pushes the top column as the turntable rotates, the top column will not collide with the turntable when it resets under the action of the tension spring.

[0015] Preferably, each of the molding plates has an auxiliary feeding component on its top surface. The auxiliary feeding component includes a thin sheet that slides against the top surface of the molding plate. The sliding direction of the thin sheet is the reciprocating sliding of the fixed slide to the positioning shaft. The thin sheet also has several straight grooves that are equidistantly distributed in a straight line. A transmission component is also provided between the thin sheet and the positioning shaft. Each straight groove covers the outside of several molding cavities. When the molding plate is flipped, the thin sheet slides a short distance on the surface of the molding plate, touching the granular pet food.

[0016] Preferably, the transmission component includes a gear differential fixedly mounted on the end of the sleeve frame away from the fixed carriage. The end of the positioning shaft is driven and assembled with the input end of the gear differential. The outer surface of the positioning shaft is rotatably fitted with drive gears of the same number as the thin plates. The drive gears are also provided with concentrically distributed concentric annular grooves. The end face of the thin plate near the forming plate is provided with a tooth groove. The thin plate is movably meshed with the drive gears through the tooth grooves. One arc surface of the concentric annular groove is fixedly provided with a plurality of circumferentially equidistant teeth. The output end of the gear differential is fixedly provided with a drive shaft. The drive shaft movably passes through the concentric annular groove. The outer surface of the drive shaft is fixedly fitted with a third gear. The third gear is meshed with the concentric annular groove through its teeth. When the forming plate deflects with the positioning shaft, the gear differential can cause the drive shaft to rotate with the third gear. The third gear can then cause the thin plate to slide through the drive gears.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This invention can receive a quantitative mixture of pet food from the extrusion nozzle through a receiving unit. Since the pore-forming unit is located inside the receiving unit, there will be a certain number of pores in the granular pet food that has been steamed and formed inside the receiving unit. The number of pores is constant. After the steamed granular pet food is baked and hardened, a finished product of granular pet food with pores can be obtained. The number of pores in each pet food is consistent, which can ensure the crispness of the same batch of pet granular food and facilitate the digestion of the food by pets.

[0030] 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.

[0031] Example 1: Please refer to Figures 1-4 , Figures 8-10 The diagram shows a processing device for the internal void structure of pet food pellets, comprising: a machine base 1, a vertical mixing extruder 2 fixedly mounted on the top of the machine base 1, and several extrusion nozzles 3 fixedly mounted on the side wall of the machine base 1 in a straight line at equal intervals. The several extrusion nozzles 3 are interconnected with the vertical mixing extruder 2, and the vertical mixing extruder 2 is used to quantitatively extrude the mixed pet food raw materials through the several extrusion nozzles 3. The vertical mixing extruder 2 is a commonly used device in the prior art, capable of mixing multiple food raw materials, mixing them into a paste, and then quantitatively extruding the paste through the extrusion nozzles 3.

[0032] It also includes: a receiving unit for receiving the pet food mixture extruded quantitatively from several extrusion nozzles 3, the receiving unit being located below the extrusion nozzles 3;

[0033] The pore-forming unit is used to create pores in the pet food mixture inside the receiving unit.

[0034] The receiving unit includes a fixed slide 4 distributed at the bottom of the machine base 1, and the fixed slide 4 is fixed in position relative to the machine base 1. A sleeve frame 5 is slidably fitted on the outside of the fixed slide 4. The sleeve frame 5 is located directly below the extrusion nozzle 3, and the fixed slide 4 is located on one side of the sleeve frame 5. The end face of the sleeve frame 5 away from the fixed slide 4 is open, and a positioning shaft 9 is rotatably mounted on the open end face of the sleeve frame 5. Several forming plates 6 are arranged in parallel inside the sleeve frame 5, and the end of the forming plate 6 away from the fixed slide 4 is fixedly fitted on the outside of the positioning shaft 9. Each forming plate 6 A support plate 8 is placed below each end away from the positioning shaft 9, and the support plate 8 is fixedly assembled with the sleeve 5. The top surface of the forming plate 6 has several forming cavities 7 arranged in a matrix. The forming cavities 7 are used to receive the pet food mixture extruded quantitatively by the extrusion nozzle 3. The sleeve 5 can slide on the fixed slide 4. The sleeve 5 can be driven to slide on the fixed slide 4 by the cooperation of the electric motor, threaded rod and threaded slider in the prior art, so that the mixture can be added into each forming cavity 7 by several extrusion nozzles 3.

[0035] The hole-making unit includes several receiving cavities 44 formed inside the molding plate 6. Each receiving cavity 44 is located between two adjacent molding cavities 7 that are distributed laterally. Inside each molding cavity 7, two symmetrically distributed docking rods 32 are slidably assembled. The end faces of the two docking rods 32 that are far apart from each other are fixedly provided with sliding shafts 33 that are slidably embedded inside the molding cavity 7. The end faces of the two docking rods 32 that are close to each other are fixedly provided with first racks 35, and the two first racks 35 are staggered vertically. The interior of the molding plate 6 is equipped with a rotating shaft 34 that rotates longitudinally. The outer surface of the rotating shaft 34 is fixedly fitted with first gears 36 that mesh with the two first racks 35. Each molding plate 6 is provided with a triggering component and an ejector component at the end near the fixed slide 4. Since the sliding shafts 33 are embedded inside the molding cavity 7, when the mixed raw material is added into the molding cavity 7, the mixed raw material will wrap around the ends of the several sliding shafts 33.

[0036] The actuating component includes a limiting frame 10 that is slidably mounted on one end face of the molding plate 6 near the fixed slide 4. A second rack 37 is also slidably embedded inside the molding plate 6, and the second rack 37 is perpendicular to the rotating shaft 34. A second gear 38 that meshes with the second rack 37 is also fixedly mounted on the outer surface of each rotating shaft 34. A connecting rod 12 that is perpendicularly distributed is fixedly provided on the end face of the second rack 37 away from the positioning shaft 9. A hollow stepped groove 11 is opened on the outer wall of the limiting frame 10, and the connecting rod 12 slides through the stepped groove 11. A connecting piece 19 is also fixedly provided on one end face of the molding plate 6 near the fixed slide 4, and a first spring 18 is fixedly provided between the top of the connecting piece 19 and the limiting frame 10. A limiting component is also provided on the top of the limiting frame 10. The steps of the stepped groove 11 are inclined. When the limiting frame 10 moves downward, the second rack 37 can be pushed by the engagement of the connecting rod 12 with the stepped groove 11.

[0037] The limiting component includes a rotating column 16 rotatably mounted on the top of the limiting frame 10, and a limiting piece 17 is fixedly sleeved on the lower outer surface of the rotating column 16. Each molded plate 6 has a handle 14 fixedly installed on its upper end face. The handle 14 is located on the side of the molded plate 6 near the limiting frame 10, and the handle 14 is used to lift and swing the molded plate 6. The side wall of the handle 14 near the limiting frame 10 has an axially distributed annular groove 15, and the annular groove 15 limits the limiting piece 17. The handle 14 makes it easy for the operator to flip the entire structure on the molded plate 6. Moreover, through the action of the annular groove 15, when the limiting frame 10 is pressed by the rotating column 16, the limiting piece 17 is locked in the position of the annular groove 15 by the deflection of the rotating column 16, which can prevent the limiting frame 10 from automatically resetting.

[0038] The ejector component includes a tray 20 slidably fitted inside each molding cavity 7. Movable plates 21 are distributed directly below the molding plate 6, and connecting posts are fixedly installed between several trays 20 and the movable plates 21. The connecting posts slide through the molding plate 6. Four pins 22 arranged in a matrix are fixedly installed at the bottom of the molding plate 6, and the pins 22 slide through the movable plates 21. Each pin 22 has a retaining ring fixedly installed on its end face away from the molding plate 6, and a tension spring 23 is fixedly installed between the end of the retaining ring near the molding plate 6 and the movable plate 21. A knocking rod 31 is rotatably suspended from the lower end face of the molding plate 6. The knocking rods 31 are distributed near the fixed plate 6. On one side of the fixed slide 4, a connecting rod 32 is fixedly installed on the lower end face of the movable plate 21, and the connecting rod 32 is also located on the side of the movable plate 21 close to the fixed slide 4. The two ends of the striking rod 31 are directly below the limiting frame 10 and the connecting rod 32, respectively. The bottom of the limiting frame 10 is arc-shaped. When the limiting frame 10 moves downward, after several sets of sliding shafts 33 exit from the inside of the forming cavity 7, the continued downward movement of the limiting frame 10 can press the striking rod 31, and push the connecting rod 32 and the movable plate 21 upward through the other end of the striking rod 31. The movable plate 21 can then push several trays 20 upward through the connecting column.

[0039] Working principle: The pet food pelleting process is as follows: the pet food mixture is stirred into a paste, the paste mixture is extruded into the forming cavity 7, the mixture in the forming cavity 7 is steamed and shaped, the steamed and shaped pellets are cooled and then baked, and finally a hard pellet pet food product is obtained.

[0040] Based on the above granulation process, the forming plate 6 is inside the frame 5. The frame 5 slides to move the forming plate 6 to below the extrusion nozzle 3. The extrusion nozzle 3 quantitatively delivers the paste mixture into the forming cavity 7. At this time, the frame 5 carries the forming plate 6 to the high-temperature steaming station to steam the paste mixture in the forming cavity 7 and make it into a granular whole. Since several sliding shafts 33 are inserted inside each forming cavity 7, after the paste mixture in the forming cavity 7 is formed, several holes will be formed inside the granular whole. After the steamed granular whole cools down, it can be taken out and baked hardened.

[0041] When the cooled granular product is removed from the molding cavity 7, the operator can press the limiting frame 10 through the rotating column 16. During the pressing process, the connecting rod 12 is limited by the stepped groove 11, and the connecting rod 12 can push the second rack 37. Through the meshing transmission of the second gear 38, the rotating shaft 34 can drive the two first racks 35 to move synchronously in opposite directions through the first gear 36, so that the sliding shaft 33 in the molding cavity 7 retracts into the interior of the receiving cavity 44. At this time, the holes inside the granular product can be exposed. When the sliding shaft 33 is completely retracted, and the limiting frame 10 continues to move downward, the docking rod 32 can be pushed upward by the knocking rod 31. When the movable plate 21 moves upward, the tray 20 inside each molding cavity 7 can be moved upward, and the granular product in the molding cavity 7 can be removed.

[0042] Furthermore, by rotating the rotating column 16, the limiting piece 17 at the bottom of the rotating column 16 can be locked in the position of the annular groove 15, preventing the limiting frame 10 from resetting due to the elastic force of the first spring 18. Moreover, when the limiting piece 17 is locked in the position of the annular groove 15, the upper end surface of the tray 20 and the upper end surface of the molding plate 6 are at the same level, so that the workers can unload the ejected granular products.

[0043] Example 2: Please refer to Figure 6 and Figure 7 This embodiment is a further explanation of Embodiment 1. A vibration component is also provided between each molding plate 6 and the sleeve frame 5. The vibration component includes a retainer 24 located below each movable plate 21. Each retainer 24 is fixed to the sleeve frame 5. A first rotating shaft 26 is rotatably mounted inside each retainer 24. A turntable 25 is fixedly fitted onto the end face of the first rotating shaft 26 near the molding plate 6. A top column 30 is fixedly mounted at the center of the end face of the movable plate 21 away from the molding plate 6. A plurality of circumferentially equidistant rings are fixedly mounted on the end face of the turntable 25 near the molding plate 6. The distributed arc-shaped right-angled trapezoidal blocks 29 push the top column 30. The side wall of the sleeve frame 5 is equipped with a second rotating shaft 27, and the second rotating shaft 27 is connected to the first rotating shaft 26 through a synchronous gear belt. The outer surface of the second rotating shaft 27 is fixedly fitted with a rubber wheel 28, and the rubber wheel 28 extends out of the sleeve frame 5 to contact the fixed slide 4. The rubber wheel 28 is in extrusion contact with the side wall of the fixed slide 4, that is, when the sleeve frame 5 slides on the fixed slide 4, the rubber wheel 28 can roll due to friction.

[0044] The length of the top post 30 is less than the height of the arc-shaped right-angled step block 29. That is, after the arc-shaped right-angled step block 29 follows the rotation of the turntable 25 to push the top post 30, the top post 30 will not collide with the turntable 25 when it is reset under the action of the tension spring 23.

[0045] In this embodiment: when the molding cavity 7 is filled with the mixed material, as the sleeve 5 moves towards the steaming station with the molding plate 6, the rubber wheel 28 will rotate due to contact with the fixed slide 4, thereby rotating the turntable 25 through the first rotating shaft 26. During the rotation, the turntable 25 can continuously push and release the top column 30 through the arc-shaped right-angled trapezoidal block 29. There are two ways in this process:

[0046] Method 1: If the elastic force of the four tension springs 23 is less than the overall weight of the molding plate 6, the position of the molding plate 6 will not move, while the movable plate 21 will frequently axially reciprocate under the action of the tension springs 23. Each time the movable plate 21 elastically and quickly resets under the action of the tension springs 23, the tray 20 will collide with the bottom of the molding cavity 7, thereby making the paste mixture in the molding cavity 7 more flat and compact.

[0047] Method 2: If the elastic force of the four tension springs 23 is greater than the overall weight of the molding plate 6, when the arc-shaped right-angled step block 29 lifts the top column 30 and then releases it instantly, it can deflect the entire molding plate 6 around the positioning shaft 9 at a small angle and then instantly reset it. During the reset process, it will hit the receiving plate 8. The vibration generated by the hitting can also make the paste mixture in several molding cavities 7 more flat and compact.

[0048] Example 3: Please refer to Figure 4 and Figure 5 This embodiment is a further explanation of Embodiment 1. Each molding plate 6 has an auxiliary feeding component on its top surface. The auxiliary feeding component includes a thin sheet 13 that slides against the top surface of the molding plate 6. The sliding direction of the thin sheet 13 is the reciprocating sliding of the fixed slide 4 to the positioning shaft 9. The interior of the thin sheet 13 also has several straight grooves that are equidistantly distributed in a straight line. A transmission component is also provided between the thin sheet 13 and the positioning shaft 9. Each straight groove covers the outside of several molding cavities 7. When the molding plate 6 is flipped, the thin sheet 13 will slide a short distance on the surface of the molding plate 6 to touch the granular pet food.

[0049] The transmission components include a gear differential 39 fixedly mounted at the end of the sleeve 5 away from the fixed slide 4. The end of the positioning shaft 9 is connected to the input end of the gear differential 39 for transmission. The outer surface of the positioning shaft 9 is rotatably fitted with drive gears 40, the same number as the thin plate 13. The drive gears 40 also have concentric annular grooves 41 arranged concentrically inside. The end face of the thin plate 13 near the forming plate 6 has a toothed groove, and the thin plate 13 engages with the drive gears 40 through the toothed groove. One arc surface of the concentric annular groove 41 is fixed. The gear differential 39 is equipped with several teeth that are equidistantly distributed in a circle. The output end of the gear differential 39 is fixedly equipped with a drive shaft 43, which movably passes through the concentric ring groove 41. A third gear 42 is fixedly sleeved on the outer surface of the drive shaft 43, and the third gear 42 is meshed with the concentric ring groove 41 through the teeth. When the forming plate 6 deflects with the positioning shaft 9, the gear differential 39 can make the drive shaft 43 rotate with the third gear 42, and the third gear 42 can make the thin plate 13 slide through the drive gear 40.

[0050] In this embodiment: when unloading the granular products ejected from the tray 20, because the granular products adhere tightly to the upper surface of the tray 20 during the steaming and forming process, they are prone to sticking. When the forming plate 6 is tilted at a certain angle by the handle 14, all the granular products will not automatically roll off and separate from the tray 20. Therefore, in this solution, when the forming plate 6 deflects with the positioning shaft 9, the rotation of the positioning shaft 9 can activate the gear differential 39, thereby causing the drive shaft 43 to rotate with the third gear 42. Since the drive gear 40 and the gear differential 39 are rotated, the gear differential 39 can be activated. The lower end face of the thin plate 13 meshes, and the third gear 42 meshes with one of the arc surfaces of the concentric ring groove 41. Therefore, the rotation of the third gear 42 can cause the drive gear 40 to change the position of the thin plate 13. When the thin plate 13 slides on the surface of the forming plate 6, it can cut the connection between the tray 20 and the granular product. By cutting, when the granular product is separated from the tray 20, several granular products can roll directly into the collection box when the operator flips the forming plate 6 with the handle 14, and there will be no sticking or falling off.
