Description

Technical Field

[0001] This invention relates to the field of food processing and production, specifically to a cleaning mechanism for an extruder used for processing squid paste. Background Technology

[0002] Squid paste is a paste-like product made from squid through a series of processing steps. It can be used to make various squid products, such as squid balls, squid sausages, and squid cakes, to meet consumers' diverse food needs. For example, when making squid balls, squid paste is mixed with starch, egg whites, and other ingredients. After stirring evenly, it needs to be extruded into ball shapes. When using an extruder to process squid paste, in order to ensure the hygiene of the production process and the quality of the product, the extruder needs to be effectively cleaned. The function of this cleaning mechanism is to clean all parts of the extruder, remove residual squid paste, grease, seasonings, and contaminants such as bacteria that may grow, in order to meet customers' strict requirements for food hygiene and quality.

[0003] Existing squid surimi extruders typically include a hopper, drive shaft, and screw propeller. The hopper holds the squid surimi raw material to be processed. The drive shaft rotates under the drive of a power system, which in turn drives the screw propeller connected to it. When the screw propeller rotates, the squid surimi in the hopper is pushed forward along the barrel by the screw threads. The squid surimi is subjected to squid compression and pushing forces and is extruded through the outlet to form the desired shape or state. After using the squid surimi extruder, there is residual squid surimi on the surface of the hopper, drive shaft, and screw propeller. During cleaning, these parts need to be disassembled and cleaned manually. However, because the upper part of the hopper is cylindrical and the lower part is conical, with a relatively high depth, it is impossible to guarantee that it can be thoroughly cleaned manually. Moreover, disassembly and cleaning increases the efficiency of manual cleaning. Secondly, the screw propeller has deep and dense threaded grooves, and the space at the connection with the drive shaft is narrow, making it difficult to clean later. If cleaning is not thorough, the residual squid surimi will breed bacteria and microorganisms, affecting the hygienic quality of the squid surimi processed later.

[0004] Therefore, it is necessary to propose a cleaning mechanism for an extruder used for squid paste processing to solve the above-mentioned technical problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a cleaning mechanism for an extruder used for squid paste processing. This mechanism solves the technical problems of the squid paste extruder, such as the special shape and depth of the hopper making it difficult to clean thoroughly by hand, which affects cleaning efficiency; and the deep and dense threaded grooves of the screw propeller, with a narrow space at the connection with the drive shaft, making cleaning difficult, easy for bacteria to grow, and affecting the hygiene quality of subsequent processing.

[0013] Preferably, an inclined limiting plate is installed at the end of the slot away from the rotating rod, with the bottom end of the limiting plate facing the center of the hopper.

[0014] Preferably, the horizontal rotating assembly includes a protrusion slidably connected to the end of the fixed disk away from the central axis of the threaded rod.

[0019] Beneficial effects:

[0020] (1) By setting up a material barrel cleaning assembly, the first nozzle is arranged at an angle. During the descent, it can spray the residual material on the cylindrical part of the hopper along the bottom of the hopper, effectively preventing the residual material from leaking to the outside of the hopper. The second nozzle can clean the residual material in the conical part of the hopper.

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] like Figures 1-4As shown, a cleaning mechanism for an extruder used for processing squid paste includes an extrusion seat 1. A rotatable drive shaft 11 is disposed on one side of the extrusion seat 1, and a spiral propulsion plate 12 is disposed on one side of the drive shaft 11. A transversely arranged cross seat 13 is snapped onto the side of the extrusion seat 1 away from the drive shaft 11. A rotatable hopper 14 is snapped onto the cross seat 13. The hopper 14 includes a cylindrical body and a conical body installed below the cylindrical body. Multiple first nozzles 15 and multiple second nozzles 16 are disposed on the hopper 14. The barrel cleaning assembly 2, mounted on the drive shaft 11, synchronously drives the first nozzle 15 and the second nozzle 16 to move along the interior of the hopper 14. The barrel cleaning assembly 2 includes two electric push rods 21 mounted above the extrusion seat 1. A movable disk 22 is snapped onto the moving end of each electric push rod 21. A threaded rod 23 is slidably connected to the middle of the movable disk 22. The lower part of the drive shaft 11 is fixedly connected to the top of the threaded rod 23. A turntable 24 is slidably connected above the threaded rod 23 and below the movable disk 22. Turntable 24 is closely attached to the lower part of movable disc 22. A positioning head, which slides along the threaded hole of threaded rod 23, is snapped onto the inside of turntable 24. A connecting block 25 is installed on the left side of turntable 24. A water tank 26 is snapped onto the end of connecting block 25 facing away from turntable 24. Auxiliary blocks 27 are snapped onto the outer side of movable disc 22 in a circular array. A fixed disc 28 is snapped onto the lower part of auxiliary blocks 27. A rotating disc 29 is rotatably connected to the inner side of fixed disc 28. The end of water tank 26 furthest from the central axis of threaded rod 23... The water tank 26 is fixedly connected to the inner side of the rotating disk 29. Multiple first nozzles 15 are arranged in a ring array on the side wall of the fixed disk 28, and the first nozzles 15 are arranged in a downward inclined manner. The output end of the water tank 26 passes through the rotating disk 29 through a pipe and is connected to the first nozzles 15. Multiple second nozzles 16 are arranged in a ring array below the fixed disk 28, and the second nozzles 16 are arranged vertically at the top of the conical hopper 14. The output end of the water tank 26 passes through the rotating disk 29 through a pipe and is connected to the second nozzles 16.

[0037] It should be noted that when the electric actuator 21 is activated, its moving end will drive the moving disk 22 to move downward. At this time, the moving disk 22 slides along the outside of the threaded rod 23, causing the turntable 24 to slide downward as well. Since the positioning head on the turntable 24 slides along the threaded hole of the threaded rod 23, the turntable 24 will move downward as the threaded rod 23 rotates. The movement of the turntable 24 drives the water tank 26 to move through the connecting block 25. The water tank 26 is connected to the rotating disk 29, and the rotating disk 29 is rotatably connected to the fixed disk 28. Under the coordinated action of the entire mechanism, the water tank 26 can drive the first nozzle 15 and the second nozzle 16 to rotate and move along the inside of the hopper 14.

[0038] The first nozzle 15 is arranged at an angle. During the descent, it can spray the residual material on the cylindrical part of the hopper 14 along the bottom of the hopper 14, effectively preventing the residual material from leaking to the outside of the hopper 14. Specifically, when some stubborn residual material is attached to the cylindrical part of the hopper 14, the strong water flow sprayed by the first nozzle 15 at an angle will wash away and guide the residual material to the bottom of the hopper 14.

[0039] The second nozzle 16 can clean the residual substances in the conical part of the hopper 14. Specifically, the concentrated and efficient spraying of the second nozzle 16 can completely remove some difficult-to-clean residual substances accumulated in the conical part of the hopper 14.

[0040] Through the above series of coordinated operations, a comprehensive, efficient and automated cleaning of the inside of hopper 14 is achieved, effectively ensuring that the extruder remains in good working condition for the next use.

[0041] like Figure 3 , Figure 5 and Figure 6 As shown, a radial rotation assembly 211 is provided on the rotating disk 29 for driving the first nozzle 15 to clean along the conical part of the hopper 14. The radial rotation assembly 211 includes a spiral spring 212, two of which form a group. A slot 213 is opened on the side of the rotating disk 29 corresponding to the second nozzle 16. A group of spiral springs 212 are symmetrically snapped onto the side wall of the slot 213. The second nozzle 16 is rotatably connected in the slot 213. One end of the group of spiral springs 212 is snapped onto the side wall of the second nozzle 16. A vertically arranged rotating rod 214 is rotatably connected to the end of the slot 213 away from the central axis of the rotating disk 29. A cam 215 that is in close contact with the front end of the second nozzle 16 is snapped onto the lower part of the rotating rod 214. The top of the rotating rod 214 rotates through the rotating disk 29 and is fitted with a gear 216. A ring array of gear teeth 217 is installed on the inner side of the fixed disk 28. The gear teeth 217 and the gear 216 mesh with each other.

[0042] It should be noted that when the rotating disk 29 rotates, the gear 216 on it will contact the gear teeth 217 arranged in a ring on the inner side of the fixed disk 28. Due to the action of the gear teeth 217, the gear 216 rotates, which in turn drives the rotating rod 214 and the cam 215 below it to rotate together. During this process, the cam 215 squeezes the second nozzle 16, so that the second nozzle 16 is subjected to pressure towards the inside of the slot 213, thereby compressing the spiral spring 212. At this time, the second nozzle 16 will perform radial cleaning along the conical part below the hopper 14.

[0043] When gear 216 disengages from tooth 217, the squeezing effect of cam 215 on second nozzle 16 disappears, and the compressed spiral spring 212 releases its spring potential energy, pushing second nozzle 16 to reset.

[0044] Specifically, at a certain moment when the rotating disk 29 rotates, the gear 216 just contacts the tooth 217. As the rotation continues, the gear 216 rotates continuously, causing the cam 215 to gradually squeeze the second nozzle 16 inward. The spiral spring 212 is continuously compressed until the gear 216 disengages from the tooth 217. The spiral spring 212 then quickly rebounds, pushing the second nozzle 16 back to its initial position. By setting the radial rotation component 211, this invention enables the second nozzle 16 to better adapt to the shape changes of the conical part of the hopper 14, ensuring comprehensive cleaning of this part and improving the cleaning coverage and effect. Through the compression and rebound of the spiral spring 212 and the action of the cam 215, the cleaning action of the second nozzle 16 is made more flexible and versatile, enabling precise cleaning of residual substances at different positions and angles, thus enhancing the targeting and effectiveness of the cleaning.

[0045] It is worth noting that when using the radial rotation component 211, the rotating disk 29 is constantly rotating inside the hopper 14, which further improves the cleaning efficiency.

[0046] like Figure 6 As shown, an inclined limiting plate 218 is installed at the end of the slot 213 away from the rotating rod 214, with the bottom end of the limiting plate 218 facing the center of the hopper 14.

[0047] It should be noted that, since the bottom end of the limiting plate 218 faces the center of the hopper 14, its inclined shape can guide and restrict the cleaning, allowing the second nozzle 16 to clean between the conical parts inside the hopper 14, thus ensuring the accuracy and stability of the cleaning operation.

[0048] like Figures 3-7 As shown, a horizontal rotating assembly 221 is provided on the rotating disk 29 for driving the water tank 26 to clean along the cylindrical part of the hopper 14. The horizontal rotating assembly 221 includes a protrusion 222 slidably connected to one end of the fixed disk 28 away from the central axis of the threaded rod 23. One end of the protrusion 222 extends into the inside of the fixed disk 28 and is equipped with a connecting spring. The end of the connecting spring away from the protrusion 222 is fixedly connected to the inside of the fixed disk 28. A pair of limiting grooves 223 are provided on the top of the fixed disk 28. A limiting rod 224 that slides through the inside of the limiting grooves 223 is installed on one end of the protrusion 222 extending into the fixed disk 28. A driving block 226 is installed above the multiple connecting blocks 25. A return spring 227 is rotatably connected between the bottom of the first nozzle 15 and the bottom surface of the rotating disk 29.

[0049] It should be noted that when the rotating disk 29 rotates, the drive block 226 contacts the protrusion 222 slidably connected to the fixed disk 28. Once the drive block 226 contacts the protrusion 222, it applies a pushing force to the protrusion 222. At this time, the end of the protrusion 222 extending into the fixed disk 28 compresses the connecting spring. Simultaneously, the first nozzle 15 rotates on the rotating disk 29, causing the return spring 227 to be stretched. As the rotating disk 29 continues to rotate, the protrusion 222 is continuously pushed by the drive block 226, and the connecting spring is continuously compressed.

[0050] After the protrusion 222 retracts into the fixed plate 28 and disengages from the drive block 226, the potential energy stored in the connecting spring and the return spring 227 is released. The rebound of the connecting spring pushes the protrusion 222 to reset, and the contraction of the return spring 227 drives the first nozzle 15 to reset. In this continuous reciprocating process, the first nozzle 15 can spray at different angles, which facilitates the comprehensive cleaning of the cylindrical part of the hopper 14. The comprehensive and efficient cleaning of the cylindrical part of the hopper 14 helps to maintain the cleanliness and hygiene of the extruder and reduce the impact of residual substances on subsequent production.

[0051] like Figures 2-3 As shown, the spiral cleaning assembly 3 is located on one side of the drive shaft 11 and is used to clean the residual substances on the surface of the spiral propulsion plate 12. The spiral cleaning assembly 3 includes a spray plate 31 that is inclinedly snapped onto the bottom of the water tank 26. The length of the spray plate 31 is greater than the maximum radius of the spiral propulsion plate 12. The threaded hole path on the threaded rod 23 is consistent with the threaded edge path of the spiral propulsion plate 12. The upper and lower ends of the spray plate 31 are snapped onto the third nozzle 32 arranged in a linear array. The end of the spray plate 31 away from the water tank 26 is set with an arc-shaped surface. A fourth nozzle 33 is snapped onto the arc-shaped surface. The bottom of the water tank 26 passes through the spray plate 31 through a pipe and is connected to the third nozzle 32 and the fourth nozzle 33. The fourth nozzle 33 is aligned along the axial direction of the threaded rod 23.

[0052] It should be noted that when the connecting block 25 and the water tank 26 rotate downwards, because the length of the spray cleaning plate 31 is greater than the maximum radius of the spiral propulsion plate 12, and its end away from the water tank 26 is set with an arc-shaped surface, the spray cleaning plate 31 can pass through the edge of the maximum radius of the spiral propulsion plate 12. During the passage, the spray cleaning plate 31 will pass through the gap of the threaded edge of the spiral propulsion plate 12. At this time, the third nozzles 32, which are linearly arrayed and snapped onto the upper and lower ends of the spray cleaning plate 31, will spray cleaning fluid to clean the upper and lower ends of the spiral propulsion plate 12. As the movement continues, it will reach the lowest end of the spiral propulsion plate 12, thereby achieving a comprehensive cleaning of the spiral propulsion plate 12. At the same time, the fourth nozzle 33, which is snapped onto the arc-shaped surface, can clean the drive shaft 11 part on the spiral propulsion plate 12, achieving a comprehensive and in-depth cleaning of the spiral propulsion plate 12 and its connection with the drive shaft 11, ensuring that there are no dead corners in the cleaning, and greatly improving the quality and effect of the cleaning.

[0053] like Figures 8-9 As shown, the limiting component 4 is located on one side of the drive shaft 11 and is used to limit the spiral propulsion plate 12. The limiting component 4 includes an inner cylinder 41 installed inside the threaded rod 23. A linkage groove 42 is opened on the inner side of the inner cylinder 41. A compression spring 43 is installed on the inner side of the linkage groove 42. A limiting block 44 is snapped on the top of the drive shaft 11 and slides through the inner side of the linkage groove 42. U-shaped grooves 45 are opened at the front and rear ends of the inner cylinder 41. The limiting block 44 is tightly attached to one of the vertical ends of the U-shaped groove 45.

[0054] It should be noted that when the spiral propulsion plate 12 needs to be moved upward from inside the hopper 14 so that the spray cleaning plate 31 can pass through the interval of the spiral propulsion plate 12, the drive shaft 11 is manually rotated. The rotation of the drive shaft 11 drives the limit block 44 connected to it to enter the horizontal end along one of the vertical ends of the U-shaped groove 45. Then, the spring potential energy of the compression spring 43 is released. Due to the spring's thrust, the drive shaft 11 will retract inside the inner cylinder 41. Then, the drive shaft 11 is rotated again, driving the limit block 44 to enter along the other vertical end of the U-shaped groove 45. At this time, the compression spring 43 is still in a compressed state, thus fixing the spiral propulsion plate 12. This facilitates the rapid extension of the spiral propulsion plate 12 from inside the hopper 14 and creates favorable conditions for the subsequent cleaning of the spray cleaning plate 31, ensuring smooth cleaning and improving the efficiency and quality of the entire cleaning process.

[0055] like Figures 8-9As shown, the bottom end of the inner cylinder 41 is threadedly connected to an extrusion plate 411, and the inner side of the extrusion plate 411 is rotatably connected to a rotating plate. Two extrusion rods 412 are installed on the rotating plate. The bottom end of the inner cylinder 41 is provided with an extrusion groove 413 that is compatible with the extrusion rods 412. The top end of the extrusion rod 412 slides through the extrusion groove 413 and then is in close contact with the limiting block 44.

[0056] It should be noted that when the extrusion disc 411 rotates in a threaded manner, it drives the rotating plate connected to it to move. The extrusion rod 412 mounted on the rotating plate moves along with the movement of the rotating plate.

[0057] Since the top end of the extrusion rod 412 slides through the extrusion groove 413 at the bottom of the inner cylinder 41, when the extrusion disc 411 rotates and causes the extrusion rod 412 to move, the top end of the extrusion rod 412 will slide in the extrusion groove 413 and eventually come into contact with the limiting block 44 and extrude it, which can enhance the fixation and restriction of the limiting block 44, thereby preventing the spiral propulsion plate 12 from becoming unstable during rotation.

[0058] like Figures 8-9 As shown, a telescopic plate 414 is movably connected to the side wall of the inner cylinder 41 below and at one of the vertical ends of the U-shaped groove 45, and the telescopic plate 414 is in close contact with the side wall of the limiting block 44.

[0059] It should be noted that by setting the telescopic plate 414, the stability of the limiting block 44 can be increased. At the same time, when the extrusion plate 411 rotates, the extrusion rod 412 disengages downward from the extrusion groove 413. Under the action of the telescopic plate 414, the limiting block 44 can be driven to enter the vertical end of the U-shaped groove 45 at a faster speed, thus improving the limiting effect.

[0060] The working principle of this invention is as follows: First, the transmission shaft 11 is manually rotated, causing the limiting block 44 to enter the horizontal end along one vertical end of the U-shaped groove 45, releasing the potential energy of the compression spring 43. The transmission shaft 11 retracts within the inner cylinder 41. Then, the transmission shaft 11 is rotated again, causing the limiting block 44 to enter along the other vertical end. The compression spring 43 remains compressed. The spiral propulsion plate 12 is fixed, and the electric push rod 21 is activated. Its moving end drives the moving disk 22 to move downward. The moving disk 22 slides along the threaded rod 23, causing the turntable 24 to slide downward accordingly. Because the positioning head on the turntable 24 slides along the threaded hole of the threaded rod 23, the turntable 24 moves downward as the threaded rod 23 rotates. The turntable 24 drives the water tank 26 to move through the connecting block 25. The water tank 26 is connected to the rotating disk 29, and the rotating disk 29 is rotatably connected to the fixed disk 28, driving the first nozzle 15 and the second nozzle 16 to rotate and move inside the hopper 14.

[0061] When the rotating disk 29 rotates, the gear 216 contacts the gear teeth 217 on the inner side of the fixed disk 28, driving the rotating rod 214 and cam 215 to rotate. The cam 215 presses against the second nozzle 16, compressing the spiral spring 212, causing the second nozzle 16 to clean radially along the conical part of the hopper 14. When the gear 216 disengages from the gear teeth 217, the spiral spring 212 rebounds, causing the second nozzle 16 to return to its original position. The limiting plate 218 in the slot 213 guides and restricts the second nozzle 16, ensuring the accuracy and stability of the cleaning process.

[0062] When the rotating disk 29 rotates, the drive block 226 contacts the protrusion 222, applying force to the protrusion 222, causing the protrusion 222 to compress the connecting spring. The first nozzle 15 rotates, and the return spring 227 is stretched. After the protrusion 222 disengages from the drive block 226, the connecting spring and the return spring 227 rebound, and the first nozzle 15 returns to its original position, achieving spraying at different angles to thoroughly clean the cylindrical part of the hopper 14.

[0063] As the connecting block 25 and water tank 26 rotate downwards, the spray plate 31, because its length is greater than the maximum radius of the spiral propulsion plate 12 and one end is arc-shaped, can pass through the threaded edge interval along the maximum radius edge of the spiral propulsion plate 12. The third nozzle 32 sprays cleaning fluid to clean the upper and lower ends of the spiral propulsion plate 12, and the fourth nozzle 33 cleans the drive shaft 11, achieving comprehensive and thorough cleaning.

[0064] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by the present invention. The scope of protection of the present invention is defined by the appended claims and their equivalents.
