Description

Technical Field

[0001] This invention relates to the field of food processing technology, specifically to a device for uniformly mixing the nutritional components of functional taro puree. Background Technology

[0002] Functional taro puree requires the addition of various nutritional supplements for uniform mixing during processing. The mixing device is the core equipment for completing this process, and its mixing effect and operating performance directly determine the quality stability of the finished product and the production efficiency. With the increasing requirements of the food processing industry for production capacity and product homogeneity, higher requirements are also placed on the operational adaptability and working condition adaptability of the mixing equipment.

[0003] Existing taro puree mixing devices generally adopt a structure in which a mixer is mounted on a stirring shaft. In order to avoid the material from sticking to the tank wall and causing uneven mixing, a scraper is usually installed on the stirring shaft. The scraper rotates synchronously with the stirring shaft to continuously scrape off the material attached to the inner wall of the tank, so that the material stuck to the wall flows back into the main material to participate in the mixing, thereby ensuring the uniform dispersion of various nutrients.

[0004] However, the scrapers of existing mixing devices are mostly fixed structures with a fixed length, which cannot be raised or lowered along the stirring shaft. The overall cantilever length of the scraper is relatively long, resulting in high running resistance during rotation, making it difficult to adapt to the high-speed rotation of the stirring shaft. Furthermore, the pressure of the scraper on the inner wall of the tank remains constant and cannot be adjusted according to the state of the material. In the later stages of mixing, after the fluidity of the taro paste increases, the excessive pressure against the wall will aggravate the friction and wear between the scraper and the tank wall, reducing the service life of the device. At the same time, the heat generated by friction can easily cause local temperature rise in the material, affecting the quality of the finished taro paste.

[0005] Therefore, it is necessary to provide a device for uniformly mixing the nutritional components of functional taro puree to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a functional taro puree nutrient uniform mixing device, which can flexibly adjust the working height and coverage of the scraper according to the mixing process stage, effectively reduce the equivalent cantilever length of the scraper, greatly reduce the running resistance when the scraper rotates circumferentially, and adapt to the high-speed rotation of the mixing shaft.

The pressure regulating component is used to adjust the pressure of the scraper on the inner wall of the mixing tank. The stirring shaft is hollow. A magnetic lifting mechanism is disposed inside the stirring shaft. The magnetic lifting mechanism drives the sliding sleeve to rise and fall by magnetic attraction.

[0008] A further configuration of the present invention is as follows: the pressure regulating assembly includes a slider one, a slider two, a slider three, a spring one, a guide post one, a slide seat one, and a hinge seat. The slider one, slider two, and slider three are all slidably installed inside the support cylinder. The slider one and slider two are elastically connected by the spring one. The guide post one is fixedly connected to the inner wall of the support cylinder and is located between the slider two and slider three. The guide post one is vertically arranged. Two slide seats one are slidably installed on the guide post one. The slider two and slider three are each fixedly installed with a hinge seat on the middle of the side wall near the guide post one. The hinge seat is drivenly connected to the two slide seats one respectively through two connecting rods.

[0009] A further feature of the present invention is that a magnetic block is embedded in the slider three, and the magnetic block is magnetically attracted to the magnetic lifting mechanism.

[0010] A further embodiment of the present invention is that the magnetic lifting mechanism includes a lifting column and an installation cylinder fixedly installed at the bottom end of the lifting column. The lifting column passes through the stirring shaft. An electromagnet is fixedly installed inside the installation cylinder. The electromagnet is magnetically attracted to a magnetic block. The can lid is provided with a lifting drive mechanism for driving the lifting column to rise and fall.

[0011] A further configuration of the present invention is as follows: the lifting drive mechanism includes a guide rail, a second motor fixedly installed at the top of the guide rail, a screw rotatably installed inside the guide rail, and a second slide block slidably installed on the inner side of the guide rail. The output end of the second motor is fixedly connected to the top end of the screw, the screw passes through the second slide block, and the screw and the second slide block are threaded together. The top end of the lifting column is fixedly connected to the second slide block, and the guide rail is fixedly connected to the can lid through a connecting bracket.

[0012] A further feature of the present invention is that a support base is fixedly installed at the end of the sliding column away from the sliding sleeve, the scraper rod slides up and down with the support base, and the scraper rod is elastically connected to the support base through two elastic connecting elements.

[0013] A further feature of the present invention is that the elastic connecting element includes a second spring, the scraper has a groove on the side wall near the support seat, a second guide post is fixedly installed inside the groove, the second guide post penetrates the support seat and slides with the support seat, and two second springs are located above and below the support seat respectively, and the two second springs are respectively sleeved on the two second guide posts.

[0014] A further configuration of the present invention is as follows: the rotary drive mechanism includes a motor, a transmission wheel, and a transmission belt. The motor is fixedly mounted on the tank lid. The output end of the motor and the top end of the stirring shaft are both fixedly fitted with transmission wheels. The transmission belt is fitted together on the two transmission wheels.

[0015] A further feature of the present invention is that the bottom of the mixing tank is connected to a discharge port, and a solenoid valve is provided on the discharge port.

[0016] A further feature of the present invention is that a limiting protrusion is fixedly provided on the outer side of the stirring shaft, and a limiting groove is formed on the inner wall of the sliding sleeve, the limiting groove being adapted to the limiting protrusion.

[0017] In summary, the present invention has the following beneficial effects: The present invention, through the cooperation of a magnetic lifting mechanism and a sliding sleeve, enables the scraper to be adjusted axially along the stirring shaft. This allows for flexible adjustment of the scraper's working height and coverage area according to the stirring process stage, effectively reducing the equivalent cantilever length of the scraper, significantly reducing the running resistance during circumferential rotation, adapting to the high-speed rotation of the stirring shaft, and improving the mixing efficiency and operational adaptability of the device. The internal pressure adjustment component of the support cylinder enables dynamic adjustment of the positive pressure of the scraper against the inner wall of the mixing tank, matching and adjusting the wall-adhering pressure according to the viscosity changes during the taro puree mixing process. In the early stage of mixing, it ensures effective scraping of material adhering to the tank wall, preventing material clumping and uneven nutrient distribution. In the later stage of mixing, it reduces the wall-adhering pressure, effectively reducing friction and wear between the scraper and the tank wall, reducing frictional heat generation, extending the overall service life of the device, and preventing quality deterioration of the taro puree due to localized temperature increases.

[0018] This invention utilizes a symmetrical linkage transmission structure within the support cylinder to achieve synchronous reverse transmission between slider three and slider two. Combined with the adjustable magnetic attraction of the electromagnet, the pre-compression of spring one can be continuously and smoothly changed, thereby achieving stepless adjustment of the scraper's wall-adhering pressure. The transmission response during pressure adjustment is synchronous and free of rigid impact. The synchronous linkage between the electromagnet's magnetic attraction and the scraper's wall-adhering pressure simultaneously enhances the magnetic attraction force on the sliding sleeve while increasing the wall-adhering pressure, offsetting the increase in scraper running resistance and preventing slippage or lag during the sliding sleeve's lifting and rotation, ensuring the stability and reliability of the device. The bidirectional elastic connection component between the scraper and the support base absorbs the impact kinetic energy of the scraper rising and falling to the end of its stroke, preventing rigid collision damage to components. It also adapts to minor axial deviations in the tank wall, improving the fit of the scraping operation. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings in the embodiments of the present invention.

[0027] Please see Figures 1-6 In this embodiment of the invention, a functional taro puree nutrient uniform mixing device includes a mixing tank 1, a tank cover 2 fixedly disposed on the top of the mixing tank 1, a stirring shaft 3 rotatably disposed inside the mixing tank 1, a stirrer 7 fixedly disposed at the bottom end of the stirring shaft 3, and a rotary drive mechanism disposed on the tank cover 2. The rotary drive mechanism is used to drive the stirring shaft 3 to rotate. The stirring shaft 3 passes through the tank cover 2. A sliding sleeve 9 is sleeved on the stirring shaft 3. A support cylinder 10 is fixedly installed on the sliding sleeve 9. The support cylinder 10 is horizontally disposed. A sliding column 11 is slidably disposed inside the support cylinder 10. A scraper 8 is installed at the end of the sliding column 11 away from the sliding sleeve 9. The scraper 8 contacts the inner wall of the mixing tank 1. A pressure regulating component is disposed inside the support cylinder 10. The pressure regulating component is used to regulate the pressure of the scraper 8 on the inner wall of the mixing tank 1. The stirring shaft 3 is hollow. A magnetic lifting mechanism is disposed inside the stirring shaft 3. The magnetic lifting mechanism drives the sliding sleeve 9 to rise and fall by magnetic attraction. The magnetic lifting mechanism achieves non-contact transmission by magnetic attraction. The drive sleeve 9 moves smoothly up and down along the axial direction of the stirring shaft 3, driving the scraper 8 to move up and down along the inner wall of the mixing tank 1. This eliminates the need for a through-drive groove on the side wall of the stirring shaft 3, ensuring the structural strength and operational rigidity of the stirring shaft 3. The axial working height and coverage area of ​​the scraper 8 can be flexibly adjusted according to the stage of the mixing process, effectively reducing the equivalent cantilever length and working area of ​​the scraper 8, significantly reducing the running resistance when the scraper 8 rotates circumferentially, adapting to the high-speed rotation of the stirring shaft 3, and improving the overall mixing and homogenization efficiency of the taro puree. With the pressure regulating component, the positive pressure of the scraper 8 on the tank wall can be dynamically adjusted according to the viscosity changes during the taro puree mixing process. In the early stage of mixing, when the material viscosity is high and it easily adheres to the tank wall, the pressure is increased to enhance the scraping effect of the adhering material, preventing material clumping and uneven nutrient distribution. In the later stage of mixing, when the material fluidity and homogenization improve, the pressure is reduced, effectively reducing friction and wear between the tank wall and the scraper 8, reducing frictional heat generation, preventing quality deterioration of the taro puree due to localized temperature rise, and extending the overall service life of the device.

[0028] In this embodiment, preferably, the pressure regulating assembly includes a slider 15, a slider 26, a slider 38, a spring 17, a guide post 20, a slide block 21, and a hinge seat 30. Slider 15, slider 26, and slider 38 are all slidably mounted inside the support cylinder 10. Slider 15 and slider 26 are elastically connected by spring 17. The guide post 20 is fixedly connected to the inner wall of the support cylinder 10 and is located between slider 26 and slider 38. The guide post 20 is vertically arranged, and two slide blocks 21 are slidably mounted on the guide post 20. Both slider 2 (16) and slider 3 (18) have hinge seats 30 fixedly installed on the middle of their side walls near guide post 1 (20). The hinge seats 30 are connected to two slide blocks 1 (21) via two connecting rods 22. A magnet 19 is embedded in slider 3 (18), and the magnet 19 is magnetically attracted to the magnetic lifting mechanism. Specifically, one end of the connecting rod 22 is hinged to slide block 1 (21), and the other end of the connecting rod 22 is hinged to the hinge seat 30. The included angle between the connecting rods 22 on both sides of the same slide block 1 (21) is less than 170°. Its working principle is that the connecting rod 22, the hinge seats 30 on both sides, and the slide blocks 1 (21) form a symmetrical arrangement. The linkage 22 transmission structure enables slider 3 18 and slider 2 16 to maintain opposite synchronous motion. When the magnetic attraction force of the electromagnet on the magnetic block 19 increases, slider 3 18 moves axially away from the guide post 20 along the support cylinder 10. This, through linkage 22, pulls the two slide blocks 21 together along the guide post 20 towards the center. Then, through the other linkage 22, slider 2 16 is pushed to move synchronously away from the guide post 20, compressing spring 17 to increase its preload. The spring force of spring 17 is transmitted to scraper 8 via slider 15 and slide post 11, causing the scraper 8 to exert normal pressure on the inner wall of the tank. When the magnetic attraction decreases, the spring 17 rebounds and pushes the slider 16 back to the direction closer to the guide post 20. The connecting rod 22 drives the two slide blocks 21 to separate along the guide post 20 to both sides. The slider 18 moves synchronously towards the direction closer to the guide post 20. The spring preload decreases, and the positive pressure of the scraper 8 on the tank wall decreases accordingly, realizing bidirectional continuous adjustment of the wall-adhering pressure. An elastic sealing cover is provided at the end of the support cylinder 10 away from the sliding sleeve 9. The sliding post 11 passes through the elastic sealing cover and is fixedly connected to the elastic sealing cover to seal the small gap between the support cylinder 10 and the sliding post 11.

[0029] In this embodiment, preferably, the magnetic lifting mechanism includes a lifting column 28 and a mounting cylinder 29 fixedly installed at the bottom of the lifting column 28. The lifting column 28 passes through the stirring shaft 3. An electromagnet (not shown in the figure) is fixedly installed inside the mounting cylinder 29. The electromagnet is magnetically attracted to the magnetic block 19. The can lid 2 is provided with a lifting drive mechanism for driving the lifting column 28 to rise and fall. The lifting drive mechanism includes a guide rail 23, a second motor 27 fixedly installed at the top of the guide rail 23, a screw 26 rotatably installed inside the guide rail 23, and a second slide block 25 slidably installed inside the guide rail 23. The output end of the second motor 27 is fixedly connected to the top end of the screw 26. The screw 26 passes through the second slide block 25, and the screw 26 and the second slide block 25 are threaded together. The lifting column 28... The top end is fixedly connected to the slide block 25, and the guide rail 23 is fixedly connected to the tank cover 2 through the connecting frame 24. The magnetic attraction force of the electromagnet can be adjusted. During operation, the motor 27 drives the screw 26 to rotate, and the rotational motion is converted into the linear lifting motion of the slide block 25 along the guide rail 23 through the screw drive. The lifting column 28 drives the mounting cylinder 29 and the internal electromagnet to move axially synchronously. The magnetic attraction force between the electromagnet and the magnetic block 19 pulls the sliding sleeve 9 to rise and fall along the stirring shaft 3, thereby adjusting the working height of the scraper 8. The magnetic attraction force can be changed by adjusting the working current of the electromagnet. The magnetic attraction force is enhanced at the same time as the wall pressure of the scraper 8 is increased, which counteracts the increased running resistance of the scraper 8 due to the increased wall pressure, avoids slippage and lag during the lifting and lowering of the sliding sleeve 9, and ensures the stability of the device operation.

[0030] In this embodiment, preferably, a support base 12 is fixedly installed at the end of the sliding column 11 away from the sliding sleeve 9. The scraper rod 8 slides vertically with the support base 12, and the scraper rod 8 is elastically connected to the support base 12 through two elastic connecting elements. The elastic connecting element includes a second spring 14. A groove is formed on the side wall of the scraper rod 8 near the support base 12. A second guide post 13 is fixedly installed inside the groove. The second guide post 13 passes through the support base 12 and slides with the support base 12. The two second springs 14 are respectively located at... Above and below the support base 12, two springs 14 are respectively sleeved on two guide posts 13; during operation, the scraper 8 can move vertically relative to the support base 12 along the guide posts 13. The springs 14 on the upper and lower sides provide bidirectional elastic support and buffer. When the scraper 8 rises and falls to the upper and lower ends of its stroke, it absorbs the impact kinetic energy and avoids rigid collision between the scraper 8 and the bottom surface of the tank cover 2 and the inner wall of the tank bottom, protecting the end of the scraper 8 and the inner wall surface of the tank. At the same time, it can adapt to the small axial deviation of the tank wall and improve the scraper wall fit.

[0031] In this embodiment, preferably, the rotary drive mechanism includes a motor 4, a transmission wheel 5, and a transmission belt 6. The motor 4 is fixedly mounted on the can lid 2. The output end of the motor 4 and the top end of the stirring shaft 3 are both fixedly fitted with transmission wheels 5. The transmission belt 6 is fitted on both transmission wheels 5. When working, the motor 4 outputs rotational power, which transmits torque through the belt drive pair formed by the two transmission wheels 5 and the transmission belt 6, driving the stirring shaft 3 to rotate around its own axis. This synchronously drives the bottom stirrer 7 to stir and mix the taro paste in the can. At the same time, the sliding sleeve 9 drives the scraper 8 to rotate circumferentially, scraping off the material adhering to the inner wall of the can and promoting the uniform dispersion of various nutrients.

[0032] In this embodiment, preferably, the bottom of the mixing tank 1 is connected to a discharge port 31, and a solenoid valve is provided on the discharge port 31. After the mixing operation is completed, the solenoid valve receives a control signal and opens, and the taro paste mixed evenly in the tank is discharged outward through the discharge port 31 under the action of gravity. The timing and duration of discharge can be precisely controlled by the solenoid valve, and the discharge can be automated in conjunction with the stirring process, which is convenient for connecting to subsequent processing processes.

[0033] In this embodiment, preferably, a limiting protrusion 301 is fixedly provided on the outer side of the stirring shaft 3, and a limiting groove 901 is provided on the inner wall of the sliding sleeve 9. The limiting groove 901 is adapted to the limiting protrusion 301. Through the circumferential engagement of the limiting protrusion 301 and the limiting groove 901, the circumferential anti-rotation transmission between the stirring shaft 3 and the sliding sleeve 9 is realized, ensuring that the rotational torque of the stirring shaft 3 can be stably transmitted to the sliding sleeve 9 and the scraper 8. At the same time, the engagement structure does not restrict the sliding sleeve 9 from sliding along the axial direction of the stirring shaft 3, ensuring the smoothness of the lifting and lowering adjustment of the scraper 8.

[0034] Working principle: When the device is working, the rotary drive mechanism drives the stirring shaft 3 to rotate continuously. The stirrer 7 at the bottom of the stirring shaft 3 performs the main stirring and mixing of taro paste in the tank. At the same time, with the circumferential cooperation of the limiting protrusion 301 and the limiting groove 901, the sliding sleeve 9, the support cylinder 10 and the scraper 8 rotate synchronously to scrape off the taro paste adhering to the inner wall of the mixing tank 1, ensuring the uniformity of the mixture. The magnetic lifting mechanism relies on the motor 27 to drive the screw 26 to rotate, which drives the lifting column 28, the mounting cylinder 29 and the electromagnet to move vertically as a whole. The magnetic attraction between the electromagnet and the magnetic block 19 pulls the sliding sleeve 9 to move axially up and down along the stirring shaft 3, thereby changing the working height of the scraper 8. This allows the scraper 8 to complete the scraping of the wall in different height ranges in the tank as needed, shortening the actual working cantilever of the scraper 8 and reducing the rotational resistance under high-speed rotation conditions. Within the lifting stroke range, the scraper 8 can rely on the spring 14 to achieve vertical floating buffer, avoiding rigid impact at both ends of the stroke.

[0035] The device can adjust the electromagnet current according to the viscosity change during the taro puree mixing process, thereby changing the magnitude of the magnetic attraction force. When the magnetic attraction force changes, the slider 18 in the pressure adjustment component is driven by the magnetic force to move, and through the connecting rod 22, the slider 16 moves in the opposite direction synchronously, changing the pre-compression amount of the spring 17. The elastic force of the spring 17 is transmitted to the scraper 8 through the slider 15 and the sliding column 11, completing the continuous adjustment of the positive pressure of the scraper 8 on the tank wall. In the early stage of mixing, the taro puree has a high viscosity, so the magnetic attraction force is increased to increase the pressure of the scraper 8 against the wall, which can reliably scrape off the high viscosity material sticking to the tank wall and prevent the material from sticking to the wall and causing uneven distribution of nutrients. In the later stage of mixing, the taro puree has better fluidity, so the magnetic attraction force is reduced to reduce the pressure of the scraper 8 against the wall, reduce friction loss and friction heat generation, and protect the quality of the taro puree material. After the mixing is completed, the solenoid valve is opened, and the mixed taro puree is discharged from the bottom outlet 31.
