Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, specifically to an aquatic feed production and processing device. Background Technology

[0002] Aquatic feed is feed specifically designed for feeding aquatic animals such as fish and shrimp. Its quality and performance directly affect the efficiency and product quality of aquaculture. With the rapid development of the aquaculture industry, the demand for aquatic feed is constantly increasing, and the quality requirements for feed are also becoming higher and higher.

[0003] In the production and processing of aquatic feed, extrusion puffing technology is a key process. It can extrude raw materials through screws and die holes under high temperature and high pressure to form puffed pellets, thereby improving the digestibility, palatability and nutritional value of the feed.

[0004] After prolonged use, the friction between the material and the extrusion plate and the inner wall of the extrusion chamber during the extrusion process, as well as the material fatigue under high temperature and high pressure, cause the gap between the extrusion plate and the inner wall of the extrusion chamber to increase, resulting in feed scrap flying off the edges, wasting raw materials and affecting the quality of feed pellets. Utility Model Content

[0005] The purpose of this invention is to provide an aquatic feed production and processing device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides an aquatic feed production and processing device, including an extrusion chamber, an extrusion plate that slides against the inner wall of the extrusion chamber, the extrusion plate including a fixing plate, and an adjustment mechanism fixedly installed at the center of the inner wall of the fixing plate;

[0007] The adjustment mechanism includes a sleeve fixedly installed on the inner wall of the fixed plate, a bolt threaded on the inner wall of the sleeve, a rotating ring rotatably installed on the outer wall of the bolt, a support plate rotatably installed on the side wall of the rotating ring, and an adjustment plate rotatably installed at the end of the support plate.

[0008] A spring is snapped onto the outer wall of the adjusting plate, a guide post is snapped onto the end of the spring, a compression ring is fixedly installed at the end of the guide post, and an elastic cover is wrapped around the outer wall of the compression ring;

[0009] The inner wall of the fixed plate is provided with a guide groove, and the inner wall of the guide groove is slidably connected to the outer wall of the guide column.

[0010] Furthermore, a limiting plate is fixedly installed at the end of the side wall of the guide column, the outer wall of the limiting plate is slidably connected to the inner wall of the guide groove, a pressing column is fixedly installed on the top of the extrusion plate, and an extrusion device is connected to the top of the pressing column.

[0011] Furthermore, the inner wall of the extrusion chamber is provided with an extrusion cavity, and a perforated plate is snapped into the bottom of the extrusion cavity. The elastic cover is made of polyurethane rubber, and its tensile strength ranges from 30 to 50 MPa.

[0012] Furthermore, the number of guide grooves is three, and the three guide grooves are evenly distributed around the adjustment mechanism, with an angle of 120° between two adjacent guide grooves.

[0013] Furthermore, a second locking post is fixedly installed on the side wall of the adjusting plate, and the outer wall of the second locking post is engaged with the inner wall of the spring. A first locking post is fixedly installed at the end of the guide post away from the compression ring, and the outer wall of the first locking post is engaged with the inner wall of the spring.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The elastic cover on the extrusion plate, under the elastic action of the spring, always fits against the inner wall of the extrusion chamber, so that when the device is started, a good sealing and extrusion environment can be quickly formed, effectively preventing the material from overflowing from the gap before it is fully extruded and formed, ensuring the initial effect of feed extrusion processing and improving the forming rate of feed pellets.

[0016] 2. By turning the bolt, the adjusting plate moves in the opposite direction of the sleeve, thereby adjusting the elastic space of the spring and making the elastic cover fit against the inner wall of the extrusion chamber. This effectively addresses the problem of increased gap after long-term use, avoids the phenomenon of feed edge material flying out due to increased gap, reduces raw material waste, and ensures the quality and appearance of feed pellets.

[0017] 3. The guide column slides in the guide groove on the inner wall of the fixed plate, ensuring the stability of the elastic cover during movement. This allows it to move along a predetermined trajectory when subjected to external forces without deviation or shaking, further ensuring the fitting accuracy between the elastic cover and the inner wall of the extrusion chamber and improving the quality of the extrusion process.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5This utility model provides a technical solution: an aquatic feed production and processing device, including an extrusion chamber 1, an extrusion plate 2 slidingly abutting against the inner wall of the extrusion chamber 1, the extrusion plate 2 including a fixed plate 205, and an adjustment mechanism 4 fixedly installed at the center of the inner wall of the fixed plate 205; the adjustment mechanism 4 includes a sleeve 406 fixedly installed on the inner wall of the fixed plate 205, and a bolt 405 threadedly installed on the inner wall of the sleeve 406. By rotating the bolt 405, the bolt 405 and the sleeve 406 are threadedly installed. The bolt 405 moves within the sleeve 406, causing the rotating ring 404 to move. A support plate 403 is rotatably mounted on the side wall of the rotating ring 404, and an adjusting plate 401 is rotatably mounted at the end of the support plate 403. The rotating ring 404 drives the adjusting plate 401 to move via the support plate 403. A spring 204 is snapped onto the outer wall of the adjusting plate 401. One end of the spring 204 is snapped onto the snap post 402 on the side wall of the adjusting plate 401, and the other end is snapped onto the guide post 203 away from the compression ring 202. On one end of the locking post 208, this locking method allows the spring 204 to function stably, providing continuous elastic support for the elastic cover 201. The movement of the adjusting plate 401 can change the compression of the spring 204, thereby adjusting the elastic space of the spring 204. A compression ring 202 is fixedly installed at the end of the guide post 203, and the elastic cover 201 is wrapped around the outer wall of the compression ring 202. A guide groove 206 is opened on the inner wall of the fixing plate 205. The inner wall of the guide groove 206 is slidably connected to the outer wall of the guide post 203. In actual use, when the elastic cover 201 does not fit well with the inner wall of the compression chamber 101, the operator can easily adjust it by rotating the bolt 405. During the compression process, under the elastic action of the spring 204, the elastic cover 201 always tends to fit against the inner wall of the compression chamber 101, so that the elastic cover 201 fits tightly against the inner wall of the compression chamber 101 again, ensuring the sealing during the compression process, preventing material leakage, and thus ensuring the compression effect.

[0029] It should be noted that since spring 204 is engaged with locking pin 208 and locking pin 402, when spring 204 itself completely loses its elasticity, it can be directly removed and replaced with a new spring 204.

[0030] Please see Figure 3 This utility model provides a technical solution: an aquatic feed production and processing device, including three guide grooves 206. The three guide grooves 206 are evenly distributed around the adjustment mechanism 4, and the interval angle between two adjacent guide grooves 206 is 120°. The guide column 203 slides in the guide grooves 206 on the inner wall of the fixed plate 205, ensuring the stability and accuracy of the guide column 203 during movement. Due to this layout of the guide grooves 206, the guide column 203 can only move along the direction of the guide grooves 206, thereby avoiding the elastic cover 201 from deviating or shaking during movement, ensuring the fitting accuracy between the elastic cover 201 and the inner wall of the extrusion chamber 101, and thus improving the quality of extrusion processing.

[0031] Please see Figure 5 This utility model provides a technical solution: an aquatic feed production and processing device, including a limiting plate 207 fixedly installed at the end of the side wall of a guide column 203. The outer wall of the limiting plate 207 is slidably connected to the inner wall of a guide groove 206. The presence of the limiting plate 207 provides additional restriction on the movement of the guide column 203 within the guide groove 206. During equipment operation, the guide column 203 may be subjected to various external forces. Without the limiting plate 207, the guide column 203 may detach from the guide groove 206 in extreme cases, causing the entire structure to fail. This sliding connection between the limiting plate 207 and the inner wall of the guide groove 206 effectively prevents the guide column 203 from detaching from the guide groove 206, ensuring the integrity and reliability of the structure.

[0032] Please see Figure 1 This utility model provides a technical solution: an aquatic feed production and processing device, including a pressing column 3 fixedly installed on the top of the pressing plate 2, and a pressing device connected to the top of the pressing column 3. The pressure applied by the pressing device can be directly and efficiently transmitted to the pressing plate 2 through the rigid connecting parts of the pressing column 3. In the process of force transmission, the pressing column 3 can reduce energy loss and ensure that the pressure generated by the pressing device is fully applied to the pressing plate 2, thereby achieving effective extrusion of materials.

[0033] Please see Figure 4 This utility model provides a technical solution: an aquatic feed production and processing device, including a second locking post 402 fixedly installed on the side wall of an adjusting plate 401, and a first locking post 208 fixedly installed at the end of a guide post 203 away from the extrusion ring 202. Through the locking method of the second locking post 402 and the first locking post 208 with the inner wall of the spring 204, the spring 204 can be firmly fixed between the adjusting plate 401 and the guide post 203, avoiding the spring 204 from loosening or falling off during equipment operation, ensuring that the spring 204 is always in an effective working state. Furthermore, the spring 204, fixed by the second locking post 402 and the first locking post 208, can accurately transmit elastic force, so that the elastic cover 201 can maintain appropriate deformation when subjected to material extrusion, thereby effectively preventing material leakage.

[0034] Please see Figure 2This utility model provides a technical solution: an aquatic feed production and processing device, including an extrusion chamber 1 with an extrusion cavity 101 on the inner wall of the extrusion chamber 1. A perforated plate 102 is snapped into the bottom of the extrusion cavity 101. The perforated plate 102 is snapped into the bottom of the extrusion cavity 101, which increases the overall structural stability of the extrusion chamber 1. It can withstand the pressure and extrusion force of the material and prevent the bottom of the extrusion cavity 101 from deforming or being damaged due to excessive force. At the same time, the snap-fit ​​installation method makes the perforated plate 102 easy to disassemble and install. When the equipment needs cleaning or maintenance, the perforated plate 102 can be easily removed for thorough cleaning or replacement. In addition, the presence of the perforated plate 102 can generate a certain resistance to the material, so that the material is subjected to more uniform extrusion force during the extrusion process. This helps to improve the degree of extrusion of the material and make the shape, size and density of the material more in line with the requirements.

[0035] Please see Figure 2 This utility model provides a technical solution: an aquatic feed production and processing device, including an elastic cover 201 made of polyurethane rubber with a tensile strength range of 30-50 MPa. The hard and soft segments are arranged alternately in the molecular chain of polyurethane rubber. This unique molecular structure enables the elastic cover 201 to maintain structural integrity and stability when subjected to external pressure or stretching, and it is not easy to break or be damaged.

[0036] It should be noted that although there is a slight gap between the three extrusion rings 202 during the process of the extrusion rings 202 supporting the elastic cover 201, this will not have a negative impact on the normal operation of the elastic cover 201. Due to the extremely fine gap, the elastic cover 201 can maintain good integrity and sealing when supported by the extrusion rings 202. The extrusion plate 2 will continuously and stably apply extrusion pressure to the material, ensuring that the material is always within the effective extrusion range throughout the entire extrusion process, so that the material will not be squeezed out from the tiny gaps between the extrusion rings 202. This ensures the smooth progress of the extrusion operation and effectively avoids material waste and leakage, thereby improving the quality and efficiency of the extrusion process.

[0037] It should be noted that a damping rod is fixedly installed between the first clamp 208 and the second clamp 402. The damping rod passes through the inner wall of the spring 204. The damping rod can limit the excessive compression or stretching of the spring 204 when subjected to external force. The damping rod and the spring 204 work together to prevent the spring 204 from losing its elasticity or being damaged due to excessive deformation, thereby ensuring the long-term stable operation of the entire spring structure.

[0038] Working principle: Under the elastic action of spring 204, the elastic cover 201 on the extrusion plate 2 is always in contact with the inner wall of the extrusion chamber 101. One end of spring 204 is engaged with the second locking post 402 on the side wall of the adjusting plate 401, and the other end is engaged with the first locking post 208 on the guide post 203 away from the extrusion ring 202. The guide post 203 slides in the guide groove 206 on the inner wall of the fixed plate 205 to ensure the positional stability of the elastic cover 201. When the device is started, the extrusion plate 2 is pressed down, and the elastic cover 201 is in contact with the inner wall of the extrusion chamber 101, extruding the material and preventing feed edges from flying away. After long-term use, the extrusion plate 2 As the gap between the elastic cover 201 and the inner wall of the extrusion chamber 101 increases, the elasticity of the spring 204 may decrease due to prolonged use. However, the elastic cover 201 will still try to fit against the inner wall of the extrusion chamber 101 under the residual elasticity of the spring 204. When it is found that the elastic cover 201 does not fit well against the inner wall of the extrusion chamber 101, the bolt 405 is turned. The bolt 405 moves in the thread of the sleeve 406, which drives the rotating ring 404 to move. The rotating ring 404 drives the adjusting plate 401 to move in the opposite direction of the sleeve 406 through the support plate 403, thereby adjusting the elastic space of the spring 204 and making the elastic cover 201 fit against the inner wall of the extrusion chamber 101 again.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
