AI Technical Summary
The existing feather expander has a large wear on the inner wall of the puffing mechanism during use, so the entire inner wall of the puffing mechanism needs to be replaced, which is relatively expensive. At the same time, the feathers need to be cut and crushed in advance, which adds time to waste additional processes and will lose a certain amount of feather powder during the transfer and transportation process, resulting in an increase in cost.
An efficient single-screw feather extrusion expander is designed. The expansion mechanism connected in segments is convenient for the internal threaded sleeve to be replaced in segments, reducing the replacement cost, and the feather cutting effect is achieved by pushing between the push screw and the internal threaded sleeve, avoiding premature crushing.
Reduces wear and replacement costs of the inner wall of the puffing mechanism, improves service life, and saves time and reduces feather losses, improves productivity and reduces costs by reducing the crushing steps before feather treatment.

Technical Field
[0001] The utility model belongs to the technical field of feather puffing machines, and in particular relates to a high-efficiency single-screw feather extrusion puffing machine. Background Art
[0002] Puffed feather powder is a high-quality animal protein feed made by selecting animal feathers, washing feathers with water, and adding appropriate puffing agents to broiler white feathers, and puffing them with a special feather puffing machine. It is in yellow granular (or powdery) form, and a puffing machine is required in the process of feed processing. The feather puffing machine increases the pressure and temperature of the material by extruding and heating it, and the material becomes a melted plastic colloid. The moment the material is discharged from the discharge template, the pressure suddenly drops to normal pressure, and the water in the material quickly turns into superheated steam to do work and increase the volume. The volume of the material also expands rapidly to form puffed feed.
[0003] When the common feather puffing machine is in use, the spiral conveying rod is used for conveying inside the puffing mechanism, and the material is in close contact and pressurized with the inner wall of the puffing mechanism. After long-term use, the inner wall of the puffing mechanism is greatly worn, and the inner wall of the entire puffing mechanism needs to be replaced, which is costly. In addition, the existing feather puffing machine needs to cut and crush the feathers in advance before puffing, which not only adds extra processes and wastes time, but also loses a certain amount of feather powder during transportation, resulting in increased costs.

[0023] Embodiment 1:
[0024] As the instruction manual Figure 1-2 As shown, a high-efficiency single-screw feather extrusion puffing machine includes a feeding mechanism and a puffing mechanism. The feeding mechanism is composed of an inclined hanging plate conveyor 1 and a horizontal feeder 2 connected in sequence.

A double-axis feeding hopper 3 is arranged below the discharge end of the horizontal feeder 2, and the bottom of the double-axis feeding hopper 3 is connected to the puffing mechanism.
[0025] In the utility model, the puffing mechanism is composed of a feed chamber 4, an extrusion chamber 5 and a puffing chamber 6 which are connected in sequence, and the feed chamber 4, the extrusion chamber 5 and the puffing chamber 6 are all spliced together by a plurality of outer sleeves 28. A push screw 7 is arranged inside the puffing mechanism, and the bottom of the puffing mechanism is supported by a bracket 18, and a high-power reducer 19 is arranged on one side of the bracket 18 located at the feed chamber 4, one end of the push screw 7 is connected to the high-power reducer 19 through a core shaft 20, and the other side of the high-power reducer 19 is connected to a main drive motor 21.
[0026] In the utility model, an internal threaded sleeve 8 is provided inside the puffing mechanism and on the outside of the pushing screw 7. The internal thread inside the internal threaded sleeve 8 is tangent to the thread on the pushing screw 7. The length of the puffing chamber 6 is equal to the sum of the lengths of the feeding chamber 4 and the extrusion chamber 5. The internal threaded sleeve 8 is replaced with an internal sleeve 22 with holes at the end of the puffing chamber 6 close to the extrusion assembly 11. The pushing screw 7 is provided with a blocking disk 9 in the middle position of the puffing chamber 6, and the thread on the pushing screw 7 is located at the end of the blocking disk 9 away from the feeding chamber 4, and the pitch gradually decreases.
[0027] In the utility model, an electromagnetic heating coil 10 is wound around the outside of the puffing chamber 6, and an extrusion assembly 11 is provided at one end of the puffing chamber 6 away from the feeding chamber 4. The extrusion assembly 11 is composed of a material guiding chamber 23 and an extrusion plate 24. The material guiding chamber 23 is connected to the puffing chamber 6, and the diameter gradually decreases from one end of the puffing chamber 6 to the outside to match the diameter of the pushing screw 7. The extrusion plate 24 is located on the side of the material guiding chamber 23 away from the puffing chamber 6.
[0028] As the instruction manual Figure 3 As shown, the double-axis feeding hopper 3 is located on a side protrusion close to the discharge end of the horizontal feeder 2, and a second anti-arching feeding rod 15 is horizontally arranged at the protrusion of the double-axis feeding hopper 3 directly below the discharge end of the horizontal feeder 2, and two staggered spiral feeding rods 16 perpendicular to the ground are arranged inside the double-axis feeding hopper 3, and one end of the two spiral feeding rods 16 are connected by mutually meshing gears 17.
[0029] As the instruction manual Figure 4 As shown, the puffing chamber 6 is located on the outside of the extrusion component 11 and is provided with a cutting knife 12. The cutting knife 12 is arranged parallel to the extrusion component 11, and the cutting knife 12 is located on the outside of the extrusion component 11 and is provided with a collecting cover 25. A cutting motor 26 is arranged on one side of the collecting cover 25, and the output shaft of the cutting motor 26 is fixedly connected to the cutting knife 12 through a connecting rod 27.
[0030] In the specific implementation of the utility model, the main driving motor 21 drives the high-power reducer 19, and the high-power reducer 19 transmits power to the push screw 7 inside the puffing mechanism through the core shaft 20 to rotate at a high speed. The feather raw hair is lifted by the inclined hanging plate conveyor 1 to the horizontal feeder 2, and then sent to the double-axis feeding hopper 3 by the horizontal feeder 2. The feather enters the inside of the feeding cavity 4 through the feeding hopper. The high-speed rotating push screw 7 continuously and quickly shears and pushes the feather through the pusher and the thread in the internal thread sleeve 8. In this process, the feather rubs against the inner wall of the cavity to generate high temperature and high pressure, and the feather is heated and cooled in the inner wall with holes. The sleeve 22 greatly increases the friction time between the material and the inner cavity through the gradually decreasing pitch of the inner sleeve 22 and the push screw 7, thereby increasing the heating temperature of the material here and making the material expand better. At the same time, the material is molten under the dual effect of the external electromagnetic heating of the expansion chamber 6, and the high-temperature and high-pressure material is pushed to the extrusion assembly 11. The material extruded by the extrusion plate 24 is quickly cooled to normal pressure and temperature. The material undergoes molecular reorganization in this process to form an expanded material with a fluffy appearance and an internal microporous structure. The cutting knife 12 on one side cuts the expanded material into blocks, and then makes it into powder through a subsequent pulverizer.
[0031] The above describes the utility model and its implementation methods, which are not restrictive. The specific implementation method is only one of the implementation methods of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it, without departing from the purpose of the invention of the utility model, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the utility model.
