Description

Technical Field

[0001] The invention relates to the field of food processing and production, in particular to a cleaning mechanism of an extruder for processing minced squid. Background Art

[0002] Minced squid is a minced product made from squid after a series of processing. It can be used to make various squid products, such as squid balls, squid sausages, squid cakes, etc., to meet consumers' demand for diversified food. For example, when making squid balls, the squid minced squid is mixed with starch, egg white and other ingredients. After stirring evenly, an extruder is needed to form the shape of balls. When using an extruder to process squid minced squid, in order to ensure the hygiene of the production process and product quality, the extruder needs to be effectively cleaned. The function of the cleaning mechanism is to clean the various parts of the extruder and remove residual squid minced squid, grease, seasonings, and possible bacteria and other contaminants to meet customers' strict requirements for food hygiene and quality.

[0003] Existing squid mince processing extruders usually include a hopper, a transmission shaft, a screw propeller, etc. The hopper is used to hold the squid mince raw material to be processed. The transmission shaft rotates under the drive of the power system, driving the screw propeller connected thereto to rotate. When the screw propeller rotates, the squid mince in the hopper is pushed by the thread and moves forward along the barrel. The squid mince is squeezed and pushed, and is extruded through the outlet to form a desired shape or state. When the squid mince extruder is used, there is residual squid mince on the surface of the hopper, the transmission shaft, and the screw propeller. When cleaning, they need to be manually disassembled and cleaned one by one. However, since the upper part of the hopper is cylindrical and the lower part is conical, the depth is relatively high, it cannot be guaranteed that it can be fully and thoroughly cleaned during manual cleaning, and the manual cleaning efficiency will be increased during disassembly and cleaning. Secondly, the thread grooves of the screw propeller are deep and dense, and the space of the part connected to the transmission shaft is narrow, which makes it difficult to clean it later. If the cleaning is not thorough, the residual squid mince will breed bacteria and microorganisms, affecting the sanitary quality of the squid mince processed later.

DETAILED DESCRIPTION In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0021] like Figure 1-Figure 4As shown, a cleaning mechanism of an extruder for processing squid paste includes an extruder seat 1, a rotatable transmission shaft 11 is arranged on one side of the extruder seat 1, a spiral propulsion plate 12 is arranged on one side of the transmission shaft 11, a transversely arranged horizontal seat 13 is clamped and installed on the side of the extruder seat 1 away from the transmission shaft 11, a rotatable hopper 14 is clamped and installed on the horizontal seat 13, the hopper 14 includes a cylindrical body and a conical body installed below the cylindrical body, and a plurality of first nozzles 15 and a plurality of second nozzles 16 are arranged on the hopper 14, The barrel cleaning assembly 2 is arranged on the transmission shaft 11, and is used for synchronously driving the first nozzle 15 and the second nozzle 16 to move along the inside of the hopper 14. The barrel cleaning assembly 2 includes two electric push rods 21 installed above the extrusion seat 1, and the moving end of the electric push rod 21 is clamped and installed with a moving disk 22. The middle of the moving disk 22 is slidably connected with a threaded rod 23. The lower part of the transmission shaft 11 is fixedly connected to the top of the threaded rod 23, and a rotating disk 24 is slidably connected above the threaded rod 23 and below the moving disk 22. The turntable 24 is tightly attached to the lower part of the movable disk 22. A positioning head is mounted inside the turntable 24 and is slidably connected to the threaded hole of the threaded rod 23. A connecting block 25 is mounted on the left side of the turntable 24. A water tank 26 is mounted on the end of the connecting block 25 facing away from the turntable 24. An auxiliary block 27 is mounted on the outer side of the movable disk 22 in a circular array. A fixed disk 28 is mounted below the auxiliary block 27. A rotating disk 29 is rotatably connected to the inner side of the fixed disk 28. The end of the water tank 26 away from the central axis of the threaded rod 23 is It is fixedly connected to the inner side of the rotating disk 29, a plurality of first nozzles 15 are arranged in a circular 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, a plurality of second nozzles 16 are arranged in a circular array below the fixed disk 28, and the second nozzles 16 are vertically arranged at the conical top end of the hopper 14, and 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.

[0022] It should be noted that when the electric push rod 21 is started, 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. Since the positioning head on the turntable 24 slides along the threaded hole of the threaded rod 23, the turntable 24 will move downward with the rotation of the threaded rod 23. The movement of the turntable 24 drives the water tank 26 to move through the connecting block 25, and 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 synergistic effect 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; The first nozzle 15 is arranged in an inclined manner, and can spray the residual material on the cylindrical part of the hopper 14 along the bottom of the hopper 14 during the descending process, effectively preventing the residual material from leaking to the outside of the hopper 14. Specifically, when there are some relatively stubborn residual materials attached to the cylindrical part of the hopper 14, the strong water flow sprayed by the first nozzle 15 at an inclined angle will flush these residual materials and guide them to the bottom of the hopper 14. 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 residual substances that are difficult to clean accumulated in the conical part of the hopper 14.

[0023] Through the above series of coordinated operations, comprehensive, efficient and automatic cleaning of the inside of the hopper 14 is achieved, which effectively ensures that the extruder remains in good working condition when it is used next time.

[0024] like Figure 3 , Figure 5 and Figure 6 As shown, a radial rotating component 211 for driving the first nozzle 15 to clean along the conical part of the hopper 14 is provided on the rotating disk 29, and the radial rotating component 211 includes a vortex spring 212, two of which are in a group. A slot 213 is opened on one side of the rotating disk 29 corresponding to the second nozzle 16, and a group of vortex springs 212 are symmetrically clamped and installed on the side wall of the slot 213, and the second nozzle 16 is rotatably connected in the slot 213, and one end of a group of vortex springs 212 is clamped and installed on the side wall of the second nozzle 16, and the slot 213 is rotatably connected to one end of the central axis of the rotating disk 29 with a vertically arranged rotating rod 214, and a cam 215 that is tightly attached to the front end of the second nozzle 16 is clamped and installed below the rotating rod 214, and the top of the rotating rod 214 rotates through the rotating disk 29 and is installed with a gear 216, and the inner side of the fixed disk 28 is installed with gear teeth 217 in a ring array, and the gear teeth 217 and the gear 216 are meshed.

[0025] It should be noted that when the rotating disk 29 rotates, the gear 216 thereon will contact the gear teeth 217 in the annular array on the inner side of the fixed disk 28. Due to the action of the gear teeth 217, the gear 216 rotates, thereby driving the rotating rod 214 and the cam 215 below it to rotate together. In this process, the cam 215 squeezes the second nozzle 16, so that the second nozzle 16 is subjected to pressure toward the inside of the notch 213, thereby compressing the volute spring 212. At this time, the second nozzle 16 will perform radial cleaning along the conical portion below the hopper 14; When the gear 216 is disengaged from the gear teeth 217 , the squeezing effect of the cam 215 on the second nozzle 16 disappears, and the compressed volute spring 212 releases its spring potential energy to push the second nozzle 16 to reset.

[0026] Specifically, at a certain moment when the rotating disk 29 rotates, the gear 216 just contacts the gear teeth 217. As the rotation continues, the gear 216 keeps turning, causing the cam 215 to gradually squeeze the second nozzle 16 inward, and the volute spring 212 is continuously compressed until the gear 216 is disengaged from the gear teeth 217. The volute spring 212 quickly rebounds and pushes the second nozzle 16 back to its initial position. By providing a radial rotating component 211, the present invention enables the second nozzle 16 to better adapt to the shape change of the conical part of the hopper 14, thereby ensuring comprehensive cleaning of the part and improving the cleaning coverage and effect. Through the compression and rebound of the volute spring 212 and the action of the cam 215, the cleaning action of the second nozzle 16 is more flexible and changeable, and can accurately clean residual materials at different positions and angles, thereby enhancing the targetedness and effectiveness of the cleaning.

[0027] It is worth noting that when the radial rotating assembly 211 is used as above, the rotating disk 29 is always rotating inside the hopper 14, thereby further improving the cleaning efficiency.

[0028] like Figure 6 As shown, an inclined limiting plate 218 is installed at one end of the slot 213 away from the rotating rod 214 , and the bottom end of the limiting plate 218 faces the center position of the hopper 14 .

[0029] It should be noted that since the bottom end of the limit plate 218 is toward the center of the hopper 14, its inclined shape can play a guiding and limiting role, so that the second nozzle 16 can clean between the conical parts in the hopper 14, ensuring the accuracy and stability of its cleaning work.

[0030] like Figure 3-Figure 7 As shown, a horizontal rotating component 221 for driving the water tank 26 to clean along the cylindrical part of the hopper 14 is provided on the rotating disk 29, and the horizontal rotating component 221 includes a protrusion 222 slidably connected to the 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 inner side of the fixed disk 28 and is installed with a connecting spring, and the end of the connecting spring away from the protrusion 222 is fixedly connected to the inner side of the fixed disk 28, and a pair of limiting grooves 223 are opened on the top of the fixed disk 28, and the protrusion 222 extends into the inner side of the fixed disk 28. A limiting rod 224 sliding through the inner side of the limiting groove 223 is installed, and a driving block 226 is installed above the multiple connecting blocks 25, and a reset spring 227 is rotatably connected between the bottom of the first nozzle 15 and the bottom surface of the rotating disk 29.

[0031] It should be noted that when the rotating disk 29 rotates, the driving block 226 will contact the protrusion 222 slidably connected to the fixed disk 28. Once the driving block 226 contacts the protrusion 222, a thrust will be applied to the protrusion 222. At this time, the end of the protrusion 222 extending into the inner side of the fixed disk 28 will compress the connecting spring. At the same time, the first nozzle 15 will rotate on the rotating disk 29, causing the reset spring 227 to be stretched. As the rotating disk 29 continues to rotate, the protrusion 222 is continuously pushed by the driving block 226, and the connecting spring is continuously compressed.

[0032] Until the protrusion 222 retracts into the fixed disk 28 and disengages from the driving block 226, the potential energy stored in the connecting spring and the reset spring 227 is released, the rebound of the connecting spring pushes the protrusion 222 to reset, and the contraction of the reset spring 227 drives the first nozzle 15 to reset. In this reciprocating process, the first nozzle 15 can achieve spraying at different angles, thereby facilitating comprehensive cleaning of the cylindrical part of the hopper 14. Comprehensive and efficient cleaning of the cylindrical part of the hopper 14 helps to keep the extruder clean and hygienic and reduce the impact of residual substances on subsequent production.

[0033] like Figure 2-Figure 3 As shown, the spiral cleaning component 3 is arranged on one side of the transmission shaft 11, and is used for cleaning the residual materials on the surface of the spiral propulsion plate 12. The spiral cleaning component 3 includes a spray plate 31 which is obliquely clamped and installed under 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 clamped and installed with third nozzles 32 in a linear array. The end of the spray plate 31 away from the water tank 26 is arranged in an arc-shaped surface, and a fourth nozzle 33 is clamped and installed in the arc-shaped surface. The bottom of the water tank 26 passes through the spray plate 31 through a pipeline 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.

[0034] It should be noted that when the connection block 25 and the water tank 26 rotate downward, since the length of the spray plate 31 is greater than the maximum radius of the spiral propulsion plate 12, and the end thereof away from the water tank 26 is arranged in an arc surface, the spray plate 31 can pass along the maximum radius edge of the spiral propulsion plate 12. In the process of passing, the spray plate 31 will pass through the interval of the thread edge of the spiral propulsion plate 12. At this time, the third nozzle 32 in a linear array mounted at the upper and lower ends of the spray plate 31 will spray the cleaning liquid to clean the upper and lower ends of the spiral propulsion plate 12. As the movement continues, the third nozzle 32 will spray the cleaning liquid until the lowest end of the spiral propulsion plate 12 is reached, thereby achieving comprehensive cleaning of the spiral propulsion plate 12. At the same time, the fourth nozzle 33 mounted in the arc surface can clean the transmission shaft 11 on the spiral propulsion plate 12, thereby achieving comprehensive and in-depth cleaning of the spiral propulsion plate 12 and the connection part with the transmission shaft 11, ensuring no dead angle in cleaning, and greatly improving the quality and effect of cleaning.

[0035] like Figure 8-Figure 9 As shown, the limit assembly 4 is arranged on one side of the transmission shaft 11 and is used to limit the spiral propulsion plate 12. The limit assembly 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 limit block 44 that slides through the inner side of the linkage groove 42 is installed above the transmission shaft 11. U-shaped grooves 45 are opened at the front and rear ends of the inner cylinder 41. The limit block 44 is tightly attached to the inside of one of the vertical ends of the U-shaped groove 45.

[0036] It should be noted that when it is necessary to move the spiral propulsion plate 12 upward from the inside of the hopper 14 so that the spray plate 31 can pass through the interval between the spiral propulsion plate 12, the transmission shaft 11 is manually rotated, and the rotation of the transmission shaft 11 drives the limit block 44 connected thereto to enter the horizontal end along one of the vertical ends of the U-shaped groove 45, and then, the spring potential energy of the compression spring 43 is released. Due to the thrust of the spring, the transmission shaft 11 will retract inside the inner cylinder 41, and then, the transmission shaft 11 is rotated again to drive 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, thereby fixing the spiral propulsion plate 12, which is conducive to driving the spiral propulsion plate 12 to quickly extend from the inside of the hopper 14, and is convenient for creating good conditions for the cleaning of the spray plate 31 in the later stage, ensuring the smooth progress of the cleaning work, and helping to improve the efficiency and quality of the entire cleaning process.

[0037] like Figure 8-Figure 9As shown, the bottom end of the inner cylinder 41 is threadedly connected to an extrusion disk 411, and the inner side of the extrusion disk 411 is rotatably connected to a rotating plate, on which two extrusion rods 412 are mounted. The bottom end of the inner cylinder 41 is provided with an extrusion groove 413 that matches the extrusion rod 412, and the top end of the extrusion rod 412 slides through the extrusion groove 413 and fits tightly against the limit block 44.

[0038] It should be noted that when the extrusion disc 411 is threadedly rotated, the rotating plate connected thereto is driven to move, and the extrusion rod 412 installed on the rotating plate moves along with the movement of the rotating plate.

[0039] Since the top end of the extrusion rod 412 slides through the extrusion groove 413 at the bottom end of the inner cylinder 41, when the extrusion disk 411 rotates to move the extrusion rod 412, the top end of the extrusion rod 412 will slide in the extrusion groove 413, and finally contact and squeeze the limit block 44, which can enhance the fixation and restriction of the limit block 44, thereby preventing the spiral propulsion plate 12 from becoming unstable during rotation.

[0040] like Figure 8-Figure 9 As shown, a telescopic plate 414 is movably connected to the side wall below the inner cylinder 41 and located at one vertical end of the U-shaped groove 45 , and the telescopic plate 414 is tightly attached to the side wall of the limiting block 44 .

[0041] It should be noted that by setting the telescopic plate 414, the stability of the limit block 44 can be increased. At the same time, when the extrusion disk 411 is rotated, the extrusion rod 412 is disengaged downward from the extrusion groove 413. The limit block 44 can be driven by the telescopic plate 414 to quickly enter the vertical end of the U-shaped groove 45, thereby improving the limiting effect.

[0042] The working principle of the present invention is: first, manually rotate the transmission shaft 11 so that the limit block 44 enters the horizontal end along one vertical end of the U-shaped groove 45, release the potential energy of the compression spring 43, and the transmission shaft 11 retracts in the inner tube 41, and then rotate the transmission shaft 11 so that the limit block 44 enters along the other vertical end, and the compression spring 43 is still in a compressed state, fix the spiral propulsion plate 12, start the electric push rod 21, and its moving end drives the moving disk 22 to move downward, and the moving disk 22 slides along the threaded rod 23, causing the turntable 24 to slide downward accordingly. Since 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, and 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 along the inside of the hopper 14; 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 the cam 215 to rotate. The cam 215 squeezes the second nozzle 16 and compresses the volute spring 212, so that the second nozzle 16 cleans radially along the conical part of the hopper 14. When the gear 216 is disengaged from the gear teeth 217, the volute spring 212 rebounds to reset the second nozzle 16. The limiting plate 218 in the notch 213 guides and limits the second nozzle 16 to ensure the accuracy and stability of cleaning; When the rotating disk 29 rotates, the driving block 226 contacts the protrusion 222, exerts force on the protrusion 222, and compresses the connection spring, the first nozzle 15 rotates, and the return spring 227 stretches. After the protrusion 222 is separated from the driving block 226, the connection spring and the return spring 227 rebound, and the first nozzle 15 is reset, so that spraying at different angles is achieved, and the cylindrical part of the hopper 14 is fully cleaned; When the connection block 25 and the water tank 26 rotate downward, the spray plate 31, because its length is greater than the maximum radius of the spiral propulsion plate 12 and one end is an arc-shaped surface, can pass through the thread edge interval along the maximum radius edge of the spiral propulsion plate 12. The third nozzle 32 sprays cleaning liquid to clean the upper and lower ends of the spiral propulsion plate 12, and the fourth nozzle 33 cleans the transmission shaft 11, achieving comprehensive and in-depth cleaning.
