Abstract
Description
Technical Field
[0001] This utility model relates to the field of feed processing technology, and in particular to a feed extruder. Background Technology
[0002] An extruder (also known as an extruder) is a key piece of equipment in feed processing. Its working principle is based on the plasticization of materials under high temperature and pressure and the instantaneous depressurization and extrusion process. Through physical and chemical changes, the material's structure is significantly altered (e.g., expansion and porosity). When the material is extruded from the high-pressure barrel through the small holes of the die to an atmospheric pressure environment, the internal moisture instantly vaporizes (flash evaporation), causing the material to expand in volume (expansion rate can reach 3-10 times), forming a porous and loose structure. A cutting mechanism is usually installed in front of the die to cut the material to produce products of different specifications and shapes. A typical cutting mechanism has a frame containing a motor, a cutter cover, and cutters housed within the cutter cover.
[0003] Depending on the product requirements, the size and shape of the cut feed will vary, necessitating adjustments to the distance between the cutter and the die head. Current technology requires stopping the machine to open the cavity, removing the cutter cover, and then separating the universal coupling from the cutter shaft. This cumbersome disassembly and assembly process results in excessively long downtime each time, impacting production. Utility Model Content
[0004] In view of this, the purpose of this utility model is to provide a feed extruder that solves the problem in the prior art that requires stopping the machine to open the chamber, opening the cutter cover, and then separating the universal coupling and the cutter shaft; the cumbersome disassembly and assembly steps make each shutdown take too long, causing a disruption to production.
[0005] This utility model provides a feed extruder, including an extrusion mechanism, a transfer mechanism, a cutting mechanism, and a hopper mechanism. The cutting mechanism and the hopper mechanism are both disposed on the transfer mechanism, with the cutting mechanism located above the hopper mechanism. The transfer mechanism is used to drive the cutting mechanism and the hopper mechanism to move closer to or away from the power output end of the extrusion mechanism. The extrusion mechanism is used to apply shearing and extruding forces to the material and extrude the material. The cutting mechanism is used to cut the material extruded by the extrusion mechanism. The hopper mechanism is used to receive the material cut by the cutting mechanism.
[0006] Furthermore, the transfer mechanism includes a guide rail, guide wheels, and a frame. The cutting mechanism and the hopper mechanism are both mounted on the frame. The guide rail extends along the direction of the extrusion mechanism. The guide wheels are located below the frame and are rotatably connected to the guide rail.
[0007] Furthermore, the cutting mechanism includes a first motor, a motor cover, and a cutter. The cutter is located at the power output end of the first motor and inside the motor cover. The motor cover is connected to the frame via a support rod. The motor cover has a through hole, which allows the power output end of the extrusion mechanism to be inserted.
[0008] Furthermore, a window is provided on the side of the motor cover, and a protective plate is hinged to the window to cover it.
[0009] Furthermore, the motor cover has a clamp at one end near the extrusion mechanism, the through hole is provided on the clamp, and the clamp is provided with a fastening component, which is used to lock the clamp to the power output end of the extrusion mechanism.
[0010] Furthermore, the fastening assembly includes a bolt and a nut, the bolt being threadedly connected to the nut.
[0011] Furthermore, a positioning post is provided on the end face of the motor cover near the extrusion mechanism, and a positioning hole adapted to the positioning post is provided on the extrusion mechanism. The positioning post is used to be inserted into the positioning hole to position the extrusion mechanism and the motor cover.
[0012] Furthermore, the extrusion mechanism includes a third motor, a screw, a barrel, and a die head. The screw is located on the power output end of the third motor and inside the barrel. The die head is located at the end of the barrel and corresponds to the position of the cutter.
[0013] Furthermore, the screw is a twin-screw screw.
[0014] Furthermore, the hopper mechanism includes a discharge hopper, a conveyor belt, and a second drive motor. The second drive motor and the discharge hopper are both mounted on the transfer mechanism. The discharge hopper is inclined, and the conveyor belt is inclinedly mounted inside the discharge hopper and connected to the power output end of the second drive motor.
[0015] Beneficial Effects: This utility model provides a feed extruder, including an extrusion mechanism, a transfer mechanism, a cutting mechanism, and a hopper mechanism. Both the cutting mechanism and the hopper mechanism are mounted on the transfer mechanism, with the cutting mechanism positioned above the hopper mechanism. Because the transfer mechanism of this application can drive the cutting mechanism and the hopper mechanism closer to or further away from the power output end of the extrusion mechanism, the distance between the cutting mechanism and the extrusion mechanism can be adjusted without stopping the machine to open the chamber, thereby changing the size and shape of the feed and effectively improving production efficiency.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0021] Please see Figures 1 to 3 This utility model provides a feed extruder, including an extrusion mechanism 1, a transfer mechanism 2, a cutting mechanism 3, and a hopper mechanism 4. The cutting mechanism 3 and the hopper mechanism 4 are both disposed on the transfer mechanism 2, with the cutting mechanism 3 located above the hopper mechanism 4. The transfer mechanism 2 is used to drive the cutting mechanism 3 and the hopper mechanism 4 to move closer to or away from the power output end of the extrusion mechanism 1. The extrusion mechanism 1 is used to apply shearing and extruding forces to the material and extrude the material. The cutting mechanism 3 is used to cut the material extruded by the extrusion mechanism 1. The hopper mechanism 4 is used to receive the material cut by the cutting mechanism 3.
[0022] In this application, since the transfer mechanism 2 can drive the cutting mechanism 3 and the hopper mechanism 4 to move, the distance between the cutting mechanism 3 and the extrusion mechanism 1 can be quickly adjusted. Furthermore, since the hopper mechanism 4 moves together with the cutting mechanism 3, it can be ensured that the feed cut by the cutting mechanism 3 falls precisely into the hopper mechanism 4.
[0023] In one feasible embodiment, the transfer mechanism 2 includes a guide rail 21, guide wheels 22, and a frame 23. The cutting mechanism 3 and the hopper mechanism 4 are both mounted on the frame 23. The guide rail 21 extends along the direction of the extrusion mechanism 1, and the guide wheels 22 are located below the frame 23 and are tactilely connected to the guide rail 21. In this embodiment, the guide rail 21 guides and supports the guide wheels 22, ensuring that the guide wheels 22 move along a predetermined trajectory, reducing unnecessary deviations or vibrations. By providing a fixed path, the accuracy of the movement of the cutting mechanism 3 and the hopper mechanism 4 can be guaranteed, preventing deviation from the extrusion mechanism 1. The guide wheels 22 roll to reduce friction and ensure smooth movement.
[0024] In one feasible embodiment, the cutting mechanism 3 includes a first motor 31, a motor housing 32, and a cutter 33. The cutter 33 is disposed at the power output end of the first motor 31 and is located inside the motor housing 32. The motor housing 32 is connected to the frame 23 via a support rod 34. The motor housing 32 has a through hole, which allows the power output end of the extrusion mechanism 1 to be inserted. The through hole in this application allows the power output end of the extrusion mechanism 1 to be inserted, thereby providing space for the cutter 33 to cut.
[0025] In one feasible embodiment, a window 321 is provided on the side of the motor cover 32, and a protective plate 322 is hinged to the window 321 to cover it. In this embodiment, the protective plate 322 prevents feed from splashing when cut by the cutter 33. When it is necessary to replace the cutter 33 or perform maintenance, the protective plate 322 can be opened, allowing for replacement or maintenance through the window 321.
[0026] In one feasible embodiment, the end of the motor cover 32 near the extrusion mechanism 1 is a clamp 326, with a through hole provided on the clamp 326. The clamp 326 is equipped with a fastening component 323, which is used to lock the clamp 326 onto the power output end of the extrusion mechanism 1. The clamp 326 engages with the extrusion mechanism 1, ensuring that the distance between the cutter 33 and the extrusion mechanism 1 remains constant during the operation of the cutter 33, thus guaranteeing that the cut feed is uniform in size and dimensions.
[0027] In one possible embodiment, the fastening assembly 323 includes a bolt 324 and a nut 325, the bolt 324 being threadedly connected to the nut 325.
[0028] In one feasible embodiment, a positioning post 35 protrudes from the end face of the motor cover 32 near the extrusion mechanism 1. The extrusion mechanism 1 has a positioning hole 11 adapted to the positioning post 35. The positioning post 35 is inserted into the positioning hole 11 to position the extrusion mechanism 1 and the motor cover 32. This embodiment achieves precise positioning through the positioning hole 11 and the positioning post 35, and also avoids radial displacement of the entire cutting mechanism 3 during the cutting process.
[0029] In one feasible embodiment, the extrusion mechanism 1 includes a third motor 12, a screw 13, a barrel 14, and a die 15. The screw 13 is located at the power output end of the third motor 12 and is situated inside the barrel 14. The die 15 is located at the end of the barrel 14, and its position corresponds to that of the cutter 33. Specifically, raw materials (such as corn, soybean meal, etc.) enter the barrel 14 and can be pre-conditioned (by adding steam, water, or additives) using a conditioner to increase the material's moisture content (15%–30%) and flowability. The screw 13 includes a conveying section, a compression section, and a melting section. In the extrusion section, the screw 13 pushes the material forward for initial compression. In the compression section, the screw pitch decreases, the material is strongly compressed, friction generates heat, and this heat, combined with external heating from the barrel 14, raises the temperature to the gelatinization / denaturation critical point. In the melting section, the material is fully plasticized, forming a viscous flow state, and the pressure continues to rise. When the molten material passes through the small holes of the die head 15 (the hole diameter and shape determine the product form), the pressure drops sharply to atmospheric pressure, the moisture evaporates rapidly, and a honeycomb-like porous structure forms inside the material. The rotating cutter 33 cuts the extruded strip material into granules, and subsequent processes such as drying, cooling, and spraying are used to adjust the moisture and nutritional properties of the finished product.
[0030] In one feasible embodiment, the screw 13 is a twin-screw extruder. Compared to a single-screw extruder, the twin-screw extruder allows the two screws to rotate in coordination, resulting in more uniform mixing of different raw materials. This is particularly beneficial for materials with high viscosity and high moisture content, where the twin-screw extruder can achieve uniform mixing in a shorter time. Furthermore, the twin-screw extruder can efficiently expand materials in a shorter time, and due to the interaction of the screws, the plasticizing effect of the material is better, contributing to improved expansion quality and speed.
[0031] In one feasible embodiment, the hopper mechanism 4 includes a discharge hopper 41, a conveyor belt 42, and a second drive motor 43. Both the second drive motor 43 and the discharge hopper 41 are mounted on the transfer mechanism 2. The discharge hopper 41 is inclined, and the conveyor belt 42 is inclinedly positioned within the discharge hopper 41 and connected to the power output end of the second drive motor 43. In this application, the conveyor belt 42 is used to transport the cut feed, improving the convenience of feed transport and thus reducing the labor intensity of workers.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description.
