[0030] The extruder is a common equipment in feed, food and other industries, which is used to expand the material after high temperature and high pressure treatment, so as to change the shape of the material, improve the taste, sterilization and other purposes. The traditional extruder adopts a double shaft structure, wherein the double shaft extruder can improve the mixing effect and expansion quality of the material to a certain extent due to the two intermeshing screws. However, with the increase of production demand, the production capacity of the traditional double shaft extruder has been difficult to meet the needs of large-scale production. Although there are three shaft extruders on the market, their production capacity and mixing effect still have room for improvement.

[0031] Referring to Figures 1 to 6 The utility model provides a kind of five-axis extruder, it adopts the structure of five screw combinations, including one center screw 310 and four peripheral screws 320, four peripheral screws 320 are surrounded in the periphery of center screw 310, form at least four meshing areas 301, can greatly improve the production capacity of extruder, and improve the mixing quality of material, while reducing the volume and manufacturing cost of extruder.

[0032] The five-axis extruder includes a power unit 100, a screw cylinder 200 and a conveying assembly 300. The power unit 100 includes a motor 110 and a gearbox 120, the shaft of the motor 110 is connected with the input shaft of the gearbox 120, the conveying assembly 300 is connected with the output shaft of the gearbox 120, and the gearbox 120 is used to change the speed and torque to transmit the power of the motor 110 to the conveying assembly 300. The gearbox 120 can be a gear gearbox, which has the advantages of stable transmission, high carrying capacity, high conversion efficiency, compact structure and low running noise, which meets the needs of the five-axis extruder.

[0033] The screw cylinder 200 is arranged on one side of the output end of the gearbox 120, and the inside of the screw cylinder 200 forms an extrusion cavity 201 for accommodating and conveying the material. The conveying assembly 300 is arranged in the extrusion cavity 201 of the screw cylinder 200, and the material is extruded and conveyed by the cooperation of the conveying assembly 300 and the screw cylinder 200.

[0034] The conveying assembly 300 is the core point of the improvement of the extruder, which includes a center screw 310 and four peripheral screws 320. The four peripheral screws 320 are arranged around the periphery of the center screw 310, and the four peripheral screws 320 can be uniformly distributed or non-uniformly distributed in the circumferential direction of the center screw 310. The four peripheral screws 320 and the center screw 310 form at least four meshing areas 301. The meshing area 301 is the main area for mixing and expanding the material. Through the rotation and intermeshing of the screws, the material in the meshing area 301 is subjected to strong shearing, extrusion and stretching, thereby realizing efficient mixing and expansion.

[0035] The number of meshing areas 301 has a significant impact on the performance of the bulking machine, and the five-axis bulking machine disclosed by the utility model adopts five screw rods, and at least four meshing areas 301 can be formed. During the conveying of the material, the motor 110 transmits power to the conveying assembly 300 through the gearbox 120, and the central screw rod 310 and the four peripheral screw rods 320 of the conveying assembly 300 rotate together. The material moves forward in the extrusion cavity 201 of the screw cylinder 200 under the pushing of the conveying assembly 300. Since the five screw rods of the conveying assembly 300 form at least four meshing areas 301, the material will transfer between the multiple meshing areas 301 and be subjected to more shearing, extruding and stretching, thereby improving the bulking effect and mixing quality. At the same time, since the structure of the five screw rod combination is adopted, the productivity of the bulking machine is also greatly improved.

[0036] The five-axis bulking machine can be widely applied to the material bulking and mixing process in the feed and food industries. In particular, in the field of feed production, since the types of feed raw materials are various and the formula is complex, the mixing effect and productivity of the bulking machine are required to be higher, and the five-axis bulking machine can significantly improve the mixing quality and production efficiency of the feed product and reduce the production cost.

[0037] Compared with the prior art, the five-axis bulking machine disclosed by the utility model has the following advantages:

[0038] 1. Productivity is greatly improved: the structure of the five screw rod combination is adopted, at least four meshing areas 301 are formed, which is equivalent to the productivity of four double-screw bulking machines or two three-screw bulking machines, and can meet the needs of large-scale production.

[0039] 2. Improve the mixing quality: at least four meshing areas 301 can significantly improve the mixing effect of the material, so that the feed product is more uniform and delicate.

[0040] 3. Reduce the volume: since the structure of the five screw rod combination is adopted, small-diameter and small-length-diameter-ratio screw rods can be selected, and the volume and installation space of the five-axis bulking machine are close to those of the double-screw bulking machine or the three-screw bulking machine, thereby reducing the requirements on the production site.

[0041] 4. Reduce the manufacturing cost: the five-axis bulking machine can meet the requirements of high productivity and high quality while avoiding a significant increase in manufacturing cost, which helps to improve market competitiveness.

[0042] Referring to Figures 4 to 6 , the four peripheral screw rods 320 are arranged in two groups, and the relative positional relationship between each group of peripheral screw rods 320 and the central screw rod 310 is limited to an isosceles triangle or an equilateral triangle.

[0043] When a group of peripheral screws 320 and the central screw 310 are defined as an isosceles triangle, the base angle a of the isosceles triangle is a key parameter, which is set between 30° and 60°, and the angle range is based on in-depth research on material flow characteristics, screw shear force and puffing effect. For example, as shown in Figure 5 When the base angle a is 30°, the two peripheral screws 320 on the left also form a meshing area 301; as shown in Figure 6 When the base angle a is 45°, four evenly distributed meshing areas 301 are formed, the flow of the material is more uniform, and the shear force distribution is more reasonable, so that better puffing effect and higher production efficiency can be obtained.

[0044] Referring to Figure 4 When a group of peripheral screws 320 and the central screw 310 are defined as an isosceles triangle, due to the symmetry of the isosceles triangle, the flow of the material between the screws is more stable, and the risk of material jamming and screw wear can be reduced.

[0045] Referring to Figure 2 and Figure 4 In some embodiments of the utility model, two groups of peripheral screws 320 are distributed on the upper and lower sides of the central screw 310, and the height of the screw cylinder 200 will increase accordingly, but the vertical flow path of the material between the screws is optimized.

[0046] Referring to Figure 5 and Figure 6 In other embodiments of the utility model, two groups of peripheral screws 320 are distributed on the left and right sides of the central screw 310, and the width of the screw cylinder 200 will increase accordingly, but the horizontal flow path of the material between the screws is optimized.

[0047] Referring to Figure 4 and Figure 5 Each group of peripheral screws 320 and the central screw 310 form three meshing areas 301, and the five-axis puffing machine has six meshing areas 301, and the shear and mixing effect of the material is optimal, which not only improves the puffing efficiency, but also makes the taste of the puffing product more delicate and uniform.

[0048] Referring to Figure 6 In some embodiments of the utility model, each peripheral screw 320 and the central screw 310 form a meshing area 301, and four meshing areas 301 are evenly distributed along the circumference of the central screw 310. In the conveying of the material, the material can experience multiple extrusion and shearing of the four meshing areas 301, and better puffing effect and production efficiency can be obtained.

[0049] Referring to Figure 2In some embodiments of the utility model, the inner sleeve 210 is arranged in the screw cylinder 200, the inner hole shape of the inner sleeve 210 is matched with the peripheral screw 320, that is, the inner hole of the inner sleeve 210 forms the extrusion cavity 201. The inner sleeve 210 can simplify the structure of the screw cylinder 200 and reduce the cost, improve the wear resistance and service life of the screw cylinder 200, the inner sleeve 210 can be used in plurality and is sequentially arranged in the screw cylinder 200. The inner sleeve 210 is usually made of wear-resistant material, such as hard alloy or high-strength stainless steel, the inner hole shape of the inner sleeve 210 is matched with the spiral shape of the peripheral screw 320, so that the screw can cooperate with the inner sleeve 210 to realize the conveying of materials when rotating. In addition, the inner sleeve 210 can also play the role of heat insulation and heat preservation to prevent the temperature of the screw cylinder 200 from being too high.

[0050] Referring to Figure 1 The screw cylinder 200 is provided with a feeding port 220 and a discharging port 230, wherein the feeding port 220 is arranged on the outer wall of one end of the screw cylinder 200 close to the gearbox 120, and the material can smoothly enter the extrusion cavity 201. The feeding port 220 is usually connected with a hopper with a conical or funnel-shaped structure to facilitate the input and dispersion of the material. A vibrator or a mixer and other auxiliary equipment can also be arranged at the feeding port 220 to ensure that the material can be uniformly dispersed. The feeding port 220 can also be equipped with a metering device to accurately control the amount of material input. The discharging port 230 is arranged at one end of the screw cylinder 200 away from the gearbox 120. A cutting device or a box for receiving the material can also be arranged at the discharging port 230 to receive the extruded material.
