Description
Technical Field
[0001] This invention relates to the field of feed processing equipment technology, specifically to an adjustable high-efficiency extrusion device for puffed feed. Background Technology
[0002] In modern animal husbandry and aquaculture, extruded feed has been widely used due to its advantages such as good palatability, high digestibility, balanced nutrition, and ease of storage and transportation. In the production process of extruded feed, extrusion molding is a key step, and the performance of the extrusion device directly affects the quality of the feed and production efficiency.
[0003] In the production of extruded feed, the extrusion templates of some existing extrusion devices have fixed apertures, making it difficult to flexibly adjust the feed particle size according to the different growth stages and feeding needs of different animals. When it is necessary to produce feed of different diameters, the staff must manually replace the entire extrusion template. This operation is not only cumbersome but also time-consuming and labor-intensive. Therefore, it is necessary to design an adjustable and efficient extrusion device for extruded feed to solve the above problems.
[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention
[0005] The purpose of this invention is to provide an adjustable, high-efficiency extrusion device for puffed feed to solve the problems mentioned in the background art.
[0006] The technical solution adopted by this application to solve its technical problem is: an adjustable high-efficiency extrusion device for puffed feed, including a support and a feed extrusion body, the feed extrusion body being fixed on the support, and also including a feeding hopper, the feeding hopper being fixed at the discharge port at the front end of the feed extrusion body, a connecting plate being fixed at the front end of the feed extrusion body, a connecting frame being fixed on the connecting plate, a one-way screw being driven and rotated on one side of the connecting frame by a power source, a slider being sleeved on the one-way screw, an intermediate frame being fixed on the slider, a guide rod being fixed on the other side of the connecting frame, and a guide sleeve being fixed on the intermediate frame that can move along the axial direction of the guide rod.
[0007] An installation plate is fixed on the intermediate frame, and at least three extrusion templates arranged vertically are fixed on the installation plate. The diameter of the extrusion holes of the extrusion templates increases in a stepped manner from bottom to top, and the extrusion templates are adapted to the discharge port of the feed hopper.
[0008] Furthermore, an assembly ring is fixed to the front end of the feed hopper, and an assembly groove is provided on the assembly ring. Multiple springs are fixed in the circumferential direction of the assembly groove, and a sealing ring that can slide along the assembly groove is fixed to the other end of each spring. At least three sealing grooves arranged vertically and adapted to the sealing rings are provided on the mounting plate.
[0009] Furthermore, the spring causes the sealing ring to maintain a tendency to move towards the sealing groove.
[0010] Furthermore, an adjusting motor is fixed to the upper end of the connecting frame, and the output end of the adjusting motor passes through the connecting frame and is connected to the one-way lead screw.
[0011] Furthermore, limit frames are fixed on both sides of the feeding hopper, and limit plates that can slide along the limit frames are fixed on both sides of the mounting plate.
[0012] Furthermore, a connecting frame is fixed on the connecting plate, and a cutting motor is fixed on the connecting frame. A cutter is installed at the output end of the cutting motor, which is suitable for cutting the feed discharged from the extrusion hole of the extrusion template.
[0013] Furthermore, a feed hopper is fixedly connected to the rear end of the feed extruder.
[0014] By adopting the above technical solution, the problem of cumbersome operation and time-consuming and labor-intensive operation caused by the need to manually replace the extrusion template hole diameter in some existing extrusion feed extrusion devices has been solved.
[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the adjustable extruded feed high-efficiency extrusion device sets multiple extrusion templates with different apertures and installs them on the mounting plate. It uses power to drive the unidirectional screw to rotate, which drives the slider, intermediate frame and mounting plate to move in the vertical direction, thereby realizing the switching of extrusion templates with different apertures on the mounting plate. This eliminates the need for staff to manually replace the entire template, simplifies the operation process and saves time and manpower. Attached Figure Description

[0022] 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.
[0023] Please see Figure 1-5 This invention provides a technical solution: an adjustable high-efficiency extrusion device for puffed feed, comprising a support 1, a feed extrusion body 2, a feed hopper 3, a connecting plate 4, a connecting frame 5, a one-way screw 7, a sealing groove 12, a guide rod 17, and a guide sleeve 18. The support 1 serves as the supporting structure for the entire device, used to fix and support the feed extrusion body 2 and other components, ensuring the stability of the device. The feed extrusion body 2 is welded and fixed to the support 1 and is the component for extruding and processing feed. It contains an extrusion chamber, spiral extrusion blades, and related extrusion mechanisms for extruding and puffing feed raw materials.
[0024] The feed hopper 3 is welded and fixed to the discharge port at the front end of the feed extruder 2. Its function is to guide the feed raw materials extruded from the feed extruder 2 into the extrusion template 11. The connecting plate 4 is welded and fixed to the front end of the feed extruder 2 and is used to connect components such as the connecting frame 5. The connecting frame 5 is welded and fixed to the connecting plate 4, and an adjusting motor 6 is bolted to one side of it. The output end of the adjusting motor 6 is keyed to the one-way screw 7. By adjusting the rotation of the motor 6, the one-way screw 7 can be driven to rotate coaxially.
[0025] A slider 8 is threaded onto the one-way lead screw 7. When the one-way lead screw 7 rotates, the slider 8 moves along the axial direction of the lead screw 7. An intermediate frame 9 is welded and fixed to the slider 8. The other side of the intermediate frame 9 is welded and fixed to a guide sleeve 18. The guide sleeve 18 is fitted onto a guide rod 17, which is welded and fixed to the other side of the connecting frame 5. In this way, when the slider 8 moves, the intermediate frame 9 and the guide sleeve 18 move along the guide rod 17, thereby ensuring the stability of the movement of the intermediate frame 9.
[0026] A mounting plate 10 is welded and fixed to the intermediate frame 9. At least three extrusion templates 11 arranged vertically are welded and fixed to the mounting plate 10. The diameter of the extrusion orifice of these extrusion templates 11 increases in a stepped manner from bottom to top. For example, the diameter of the extrusion orifice of the bottom extrusion template 11 is 2mm, that of the middle one is 4mm, and that of the top one is 6mm. This allows for the selection of extrusion templates 11 with appropriate orifice diameters according to different production needs. The extrusion templates 11 are adapted to the discharge port of the feed hopper 3. When it is necessary to replace the extrusion template 11, the motor 6 drives the one-way screw 7 to rotate, which in turn moves the slider 8, the intermediate frame 9, and the mounting plate 10, moving the extrusion template 11 with the required orifice diameter to the discharge port of the feed hopper 3.
[0027] An assembly ring 13 is welded and fixed to the front end of the feed hopper 3. The assembly ring 13 has an assembly groove 14. Multiple springs 15 are welded and fixed to the circumference of the assembly groove 14. A sealing ring 16 is welded and fixed to the other end of the springs 15. The sealing ring 16 can slide along the assembly groove 14. The mounting plate 10 has a sealing groove 12 that matches the sealing ring 16. When the mounting plate 10 moves to the discharge port of the feed hopper 3, the sealing ring 16 will be embedded in the sealing groove 12 under the elastic action of the springs 15, thereby ensuring the sealing between the feed hopper 3 and the extrusion template 11. The sealing ring 16 is made of fluororubber, and the fit clearance with the sealing groove 12 is designed to be 0.1-0.2mm. Under the preload force (5-10N) of the springs 15, it can withstand an extrusion pressure of 0.8MPa, reducing feed raw material leakage.
[0028] Limiting frames 19 are welded and fixed on both sides of the feeding hopper 3, and limiting plates 20 are welded and fixed on both sides of the mounting plate 10. The limiting plates 20 can slide along the limiting frames 19. The setting of the limiting frames 19 and the limiting plates 20 further guides and limits the movement of the mounting plate 10, ensuring that the mounting plate 10 can move accurately to the designated position, so that the extrusion template 11 can be precisely connected with the discharge port of the feeding hopper 3.
[0029] A connecting frame 21 is welded and fixed to the connecting plate 4. A cutting motor 22 is bolted to the connecting frame 21, and a cutter 23 is keyed to the output end of the cutting motor 22. When the feed is discharged from the extrusion hole of the extrusion template 11, the cutting motor 22 drives the cutter 23 to rotate, cutting the feed into appropriate lengths. By adjusting the speed of the cutting motor 22, the cutting speed of the cutter 23 can be controlled, thereby obtaining feed particles of different lengths. The cutting motor 22 adopts frequency conversion speed regulation, with a speed range of 0-3000 r / min, corresponding to a linear speed of 0-15 m / s for the cutter 23, which can cut the extruded feed into particles of 5-50 mm with a particle length error ≤ ±1 mm.
[0030] The feed extruder 2 has a feed hopper fixed at its rear end. The feed raw materials to be processed enter the feed extruder 2 through the feed hopper. After being extruded and expanded in the feed extruder 2, they enter the feed hopper 3 from the discharge port at the front end, are then extruded through the extrusion template 11, and finally cut into finished feed by the cutter 23.
[0031] Working principle: When it is necessary to produce extruded feed of different particle sizes, firstly, the aperture of the extrusion template 11 to be used is determined according to the required feed particle size. The adjustment motor 6 is started by connecting an external power supply and the corresponding control button. The adjustment motor 6 drives the one-way screw 7 to rotate. The rotation of the one-way screw 7 causes the slider 8 to move along the axial direction of the one-way screw 7. The movement of the slider 8 drives the intermediate frame 9, the mounting plate 10 and the extrusion template 11 to move together in the vertical direction. During the movement, the guide sleeve 18 moves along the guide rod 17 and the limiting plate 20 slides along the limiting frame 19 to ensure the stability of the movement of the mounting plate 10.
[0032] When the extrusion template 11 with the required aperture is aligned with the discharge port of the feed hopper 3, the adjustment motor 6 is stopped. At this time, under the action of the spring 15, the sealing ring 16 is embedded in the sealing groove 12 on the mounting plate 10 to achieve the seal between the feed hopper 3 and the extrusion template 11.
[0033] Then, the feed raw materials to be processed are fed into the feed extruder 2 through the feed hopper. After the feed extruder 2 extrudes and puffs the raw materials, they enter the feed hopper 3 from the discharge port at the front end and are then extruded through the extrusion hole of the extrusion template 11. At the same time, the cutting motor 22 is started by the external power supply and the corresponding control button. The cutting motor 22 drives the cutter 23 to rotate and cut the extruded feed into a suitable length to obtain the required puffed feed.
[0034] If it is necessary to replace the extrusion template 11 with a different aperture, the above operation can be repeated, thus eliminating the need for workers to manually replace the entire extrusion template 11 and reducing the labor intensity of workers.
[0035] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
