Description

Technical Field

[0001] The invention belongs to the technical field of feed expansion, and in particular relates to an anti-blocking screw extrusion feed expansion machine. Background Art

[0002] Existing feeds are puffed during processing, which expands the volume of the feed, gelatinizes starch, and changes the structure of protein and fat, making it easier to digest. In addition, the puffing process can reduce the content of bacteria, mold and fungi in the raw materials, and improve the hygienic quality of the feed.

[0003] At present, a Chinese invention with the announcement number of CN104939289B discloses a quick-locking device for a screw extrusion type extruder. Existing feed extruders generally use an auger-shaped screw to extrusion-transport feed. When the screw is extruding and transporting feed, the feed at the front end will be continuously extruded backwards, thereby pushing the feed at the rear end into the extruder. Therefore, the originally very fluffy feed will become very compact after continuous extrusion. Not only is the air permeability poor, it is difficult to quickly transfer heat, resulting in low extrusion efficiency, but the mutual extrusion of feeds also easily causes the feed to agglomerate, resulting in the agglomerated feed being difficult to expand, thereby clogging the inside of the extruder, affecting the feed expansion effect. At the same time, the feed is generally discharged directly from the extruder after expansion. Since the particle size of the feed after expansion is not uniform, it cannot be directly packaged. The extruded feed needs to be crushed into particles of uniform size to facilitate subsequent feeding of livestock. Therefore, the processing efficiency of the feed will be reduced, which is not convenient for actual production and use. Summary of the invention

[0004] The purpose of the present invention is to provide an anti-clogging screw extrusion feed puffing machine, which has the advantages of ensuring the fluffiness of the feed after extrusion and transportation, preventing the puffing machine from being blocked, and improving the feed puffing effect. At the same time, the puffed feed can be crushed into particles of uniform size, which is convenient for subsequent packaging.

[0005] The above technical purpose of the present invention is achieved through the following technical solutions: an anti-clogging screw extrusion feed puffing machine, comprising a fixed base plate, a first support seat and a second support seat are bolted to both sides of the top of the fixed base plate, an puffing outer cylinder and a material conveying cylinder are respectively installed between the first support seat and the second support seat, the material conveying cylinder is installed on the top of the puffing outer cylinder, a driving motor is bolted to the side of the first support seat away from the second support seat, and a puffing mechanism and a material conveying mechanism are respectively installed inside the puffing outer cylinder and the material conveying cylinder.

[0006] By adopting the above technical solution, the second rotating rod drives the extrusion spiral disc to rotate and extrude the feed, which can not only ensure the stable transportation of the feed. At the same time, the rotating rod and the rotating blade rotate synchronously to break up the squeezed feed and chop the feed to make the feed particles uniform in size. This prevents the feed from agglomerating, ensures the fluffiness of the feed when it is transported to the inside of the extruder, prevents blockage, and improves the feed puffing effect. The first rotating rod drives the extrusion spiral ring to transport the feed, so that the feed produces a puffing reaction inside the puffing inner cylinder. After the feed is discharged from the inside of the puffing inner cylinder through the chopping hole, the sliding plate can drive the chopping hole to slide back and forth left and right, cutting the puffed feed into particles of uniform size, thereby facilitating the subsequent packaging of the feed and improving the feed processing efficiency.

[0007] The present invention is further configured as follows: the puffing mechanism includes a first rotating rod that is arranged through the inside of a puffing outer cylinder, the two ends of the first rotating rod are respectively rotatably connected to the inside of a first support seat and a second support seat, the surface of the first rotating rod is fixedly sleeved with an extrusion screw ring, and the extrusion screw ring is spirally sleeved on the surface of the first rotating rod, one end of the first rotating rod close to the first support seat and the output end of the driving motor are bolted with synchronous wheels, the surfaces of the two synchronous wheels are transmission sleeved with synchronous belts, and the inside of the puffing outer cylinder is bolted with a puffing inner cylinder sleeved on the surface of the first rotating rod.

[0008] By adopting the above technical solution, the extrusion screw ring generates heat by squeezing and rubbing the feed during the process of moving the feed, thereby heating and pressurizing the feed. When the extrusion screw ring moves the feed into the second support seat, the feed will be discharged from the inside of the puffing inner cylinder through the extrusion through hole and the cutting through hole, causing the pressure to drop suddenly, thereby causing the water inside the feed to evaporate quickly, the volume to expand rapidly, and produce a puffing reaction.

[0009] The present invention is further configured as follows: an elliptical disc is bolted to one end of the first rotating rod close to the second supporting seat, a sliding plate is slidably connected to one side of the elliptical disc inside the second supporting seat, an extrusion through hole and a chopping through hole that are interconnected are respectively provided inside the second supporting seat and the sliding plate, a side of the extrusion through hole away from the chopping through hole is connected to the interior of the puffing inner cylinder, an arc-shaped groove that is slidably connected to the elliptical disc is provided inside the sliding plate, return springs are bolted to both sides of the sliding plate, an end of the return spring away from the sliding plate is bolted to the interior of the second supporting seat, a feeding channel bolted to the first supporting seat is welded on one side of the puffing outer cylinder close to the first supporting seat, the feeding channel is connected to the interior of the puffing inner cylinder, and a first disc gear is fixedly sleeved on one end of the surface of the first rotating rod close to the first supporting seat.

[0010] By adopting the above technical solution, the first rotating rod drives the extrusion screw ring to rotate during the feed movement and puffing process, and the elliptical wheel is synchronously driven to rotate, so that the elliptical wheel slides inside the arc-shaped groove, and the action force and the rebound force of the reset spring are used to push the sliding plate to slide back and forth left and right inside the second support seat, so that the chopping through hole chop the feed entering the inside, and cut the puffed feed into particles of uniform size.

[0011] The present invention is further configured as follows: the feeding mechanism includes a second rotating rod that is arranged through the inside of the feeding cylinder, and two ends of the second rotating rod are respectively rotatably connected to the first support seat and the second support seat, and one end of the surface of the second rotating rod close to the first support seat is fixedly sleeved with a second disc gear meshing with the first disc gear, and the surface of the second rotating rod is fixedly sleeved with an extrusion screw disk, and the inside of the second rotating rod is rotatably connected to a fixed inner rod bolted to the inside of the second support seat, and the surface of the fixed inner rod is fixedly sleeved with the first bevel gear, and the surface of the second rotating rod passes through and is rotatably connected with the rotating rod, and the surface of the rotating rod is fixedly sleeved with a rotating blade, and the end of the rotating rod away from the rotating blade is bolted with the second bevel gear meshing with the first bevel gear, and the end of the feeding cylinder close to the first support seat is welded with a connecting channel bolted to the first support seat, and the connecting channel is respectively connected with the inside of the feeding cylinder and the feeding channel.

[0012] By adopting the above technical solution, the rotating rod is synchronously driven to rotate during the rotation of the second rotating rod, so that the rotating rod can break up the squeezed feed. At the same time, the second bevel gear is driven to engage with the first bevel gear that is fixed differently during the rotation of the rotating rod, thereby driving the rotating blade to rotate on the surface of the rotating rod, so that the rotating blade can crush large pieces of feed.

[0013] The present invention is further configured as follows: one side of the top of the feeding cylinder is fixedly connected to a feeding funnel, and one side of the top of the feeding funnel is hinged to a sealing cover plate.

[0014] The above technical solution makes it easy to pour the feed into the interior of the feeding cylinder, and at the same time the poured feed is filtered to reduce internal impurities.

[0015] The present invention is further configured as follows: a filter screen is bolted to the top of the inner cavity of the feed funnel.

[0016] By adopting the above technical solution, the top of the feed funnel can be covered when not in use to prevent dust and moisture from entering the interior.

[0019] The present invention is further configured as follows: a heat-insulating inner liner used in conjunction with the puffing inner cylinder is bonded to the inner surface of the puffing outer cylinder.

[0020] The above technical solution is adopted to prevent heat from being dissipated from the surface of the conveying barrel, reduce heat loss and improve the heating effect.

[0021] The present invention is further configured as follows: a ball bearing slidably connected to the sliding plate is rotatably connected inside the second support seat, and a discharge notch communicating with the shearing through hole is provided on one side of the second support seat away from the first support seat.

[0022] By adopting the above technical solution, the friction of the sliding plate sliding inside the second support seat is reduced, and the sliding stability is improved. At the same time, the expanded feed particles can be discharged through the discharge slot.

[0023] The present invention is further configured as follows: an inspection door is bolted to one side of the exterior of the first support seat and the second support seat, and a ventilation grille is bolted to the interior of the inspection door.

[0024] By adopting the above technical solution, the interior of the first support seat and the second support seat can be opened to repair and replace the internal parts, and at the same time, it is convenient to ventilate and dissipate heat for the internal equipment.

[0025] In summary, the present invention has the following beneficial effects: 1. The second rotating rod drives the extrusion screw to rotate and push the feed, which can not only ensure the stable delivery of the feed. At the same time, the rotating rod and the rotating blade rotate synchronously to break up the squeezed feed and chop the feed to make the feed particles uniform in size. This prevents feed from agglomerating, ensures the fluffiness of the feed when it is transported to the extruder, prevents blockage, and improves the feed extrusion effect; 2.

[0034] refer to Figure 1 , Figure 2 , the top of the inner cavity of the feed funnel 9 is bolted with a filter screen 10. The top of the feed funnel 9 can be covered when not in use to prevent dust and moisture from entering the interior.

[0035] refer to Figure 1 , Figure 6 The end of the puffing outer cylinder 4 close to the second support seat 3 is bolted to a fixing seat 12 bolted to the second support seat 3, a heater 13 is bolted inside the fixing seat 12, and an electric heating network 14 electrically connected to the heater 13 is mounted on the surface of the puffing inner cylinder 705.

[0038] refer to Figure 1 An inspection door 18 is bolted to one side of the outside of the first support seat 2 and the second support seat 3, and a ventilation grille 19 is bolted to the inside of the inspection door 18. The inside of the first support seat 2 and the second support seat 3 can be opened to repair and replace internal parts. At the same time, it is convenient to ventilate and dissipate heat for internal equipment.

[0039] Brief description of the use process: First, the driving motor 6 is turned on to drive the synchronous wheel 702 to rotate, and the synchronous belt 703 is used for transmission, thereby synchronously driving the first rotating rod 701 to rotate, and at the same time, the first rotating rod 701 drives the first disc gear 712 to rotate and mesh with the second disc gear 802, thereby driving the second rotating rod 801 to rotate in the opposite direction of the first rotating rod 701. Then, the feed is poured into the inside of the feeding cylinder 5, so that the second rotating rod 801 can use the extrusion screw 803 to drive the feed to move inside the feeding cylinder 5, so that the feed moves to the inside of the connecting channel 809 and falls downward into the feeding channel 711. While the feed moves inside the feeding cylinder 5, the second rotating rod 801 rotates and synchronously drives the rotating rod 806 to rotate, so that the rotating rod 806 can break up the squeezed feed. At the same time, the rotating rod 806 drives the second bevel gear 807 to engage with the first bevel gear 804 which is fixed differently during the rotation process, thereby driving the rotating blade 808 to rotate on the surface of the rotating rod 806, so that the rotating blade 808 can crush the large pieces of feed.

[0040] After that, the feed falls into the inside of the feeding channel 711. Since the first rotating rod 701 rotates in opposite directions to the second rotating rod 801, the first rotating rod 701 will use the extrusion screw ring 704 on the surface to drive the feed to move in the inside of the puffing outer cylinder 4 in the opposite direction to the feed in the puffing inner cylinder 705. The feed inside the puffing inner cylinder 705 is auxiliary heated by the electric heating network 14, and the extrusion screw ring 704 generates heat by squeezing and rubbing the feed during the process of moving the feed, thereby heating and pressurizing the feed. When the extrusion screw ring 704 moves the feed to the inside of the second support seat 3, the feed will be discharged from the inside of the puffing inner cylinder 705 through the extrusion through hole 707 and the cutting through hole 708, causing the pressure to drop suddenly, thereby causing the water inside the feed to evaporate quickly, and the volume to expand rapidly, resulting in a puffing reaction. At the same time, the first rotating rod 701 rotates and drives the extrusion screw ring 704 to move and expand the feed, thereby synchronously driving the elliptical wheel 713 to rotate, so that the elliptical wheel 713 slides inside the arc groove 709, and the action force and the rebound force of the reset spring 710 are used to push the sliding plate 706 to slide back and forth left and right inside the second support seat 3, so that the chopping through hole 708 cuts the feed entering the inside, and cuts the expanded feed into particles of uniform size.
