Description
Technical Field
[0001] This utility model relates to the field of food processing technology, and in particular to a high-speed stirring and anti-overflow structure for raw materials used in food processing. Background Technology
[0002] In modern food processing, in order to fully and evenly blend various liquid raw materials or mixtures, it is usually necessary to use stirring equipment for high-speed stirring. However, under high-speed stirring, the raw materials inside the stirring drum will be subjected to huge centrifugal force, resulting in strong turbulence and vortex. This violent fluid movement will inevitably cause the raw material liquid level to rise sharply along the drum wall. At the same time, high-speed shearing will also generate a large number of bubbles that are difficult to break, making the overall liquid surface extremely unstable and easily out of control.
[0003] Most existing mixing equipment uses fixed-shaped mixing blades. When the liquid level rises abnormally or the foam expands violently, the only way to prevent the raw material from overflowing is to manually stop the machine or cut off the power. There is a lack of a mechanical contraction and avoidance mechanism that can automatically and dynamically adjust the mixing range according to changes in the liquid level. Even if some equipment attempts to introduce foldable moving parts to change the mixing range, the gaps between these moving parts are easily invaded and filled by food residues or viscous slurries in the deep liquid. This causes the folded structure to fail mechanically when it needs to retract and slow down, and ultimately it still cannot effectively prevent the raw material from splashing and overflowing.
[0004] Therefore, this utility model proposes a high-speed stirring and anti-overflow structure for food processing raw materials to overcome the shortcomings of the prior art. Utility Model Content
[0005] In view of the problems existing in the high-speed stirring anti-overflow structure for food processing raw materials, such as the easy overflow caused by excessive turbulence of raw material liquid due to centrifugal force and the generation of a large number of bubbles during high-speed stirring of food processing, and the easy for food residue or viscous slurry to enter and jam the storage gap of the movable folding parts when it is necessary to slow down and retract, thus causing the mechanical folding anti-overflow function to fail, this utility model aims to provide a high-speed stirring anti-overflow structure for food processing raw materials with an improved structure that can effectively solve the above problems.
[0006] This utility model provides a high-speed stirring and spill prevention structure for food processing raw materials, including: a base and a stirring drum fixedly connected to the top of the base; a drive motor fixedly connected to the inner wall of the base; a transmission rod fixedly connected to the output end of the drive motor; the transmission rod extending into the interior of the stirring drum; a rotating disk fixedly connected to the outer wall of the transmission rod; a storage groove formed on the outer wall of the rotating disk; a rotating shaft rotatably connected to the outer wall of the rotating disk; and stirring blades fixedly connected to the outer wall of the rotating shaft; as well as an elastic rope fixedly connected to the interior of the storage groove and a blocking ring slidably connected to the interior of the storage groove.
[0007] The elastic rope has a structure that is fixedly connected to the stirring blade at one end away from the inner wall of the storage tank. The bottom of the blocking ring is fixedly connected to an elastic reset rod for sealing the gap, and the end of the elastic reset rod away from the blocking ring is fixedly connected to the inner wall of the storage tank.
[0008] Furthermore, the transmission rod, the rotating disk, the stirring blade, and the blocking ring are combined through the lifting and sliding engagement of the elastic reset rod and the stretching and contracting engagement of the elastic rope. This allows the blocking ring to slide upwards to fill the gap in the collection groove after the stirring blade is unfolded by centrifugal force, and to retract and avoid obstruction when the speed decreases, in conjunction with the tension of the elastic rope. This effectively overcomes the defect in the prior art where the folding mechanism is easily jammed by residue, and achieves stable anti-overflow and avoidance actions.
[0009] Preferably, a level gauge is fixedly connected to the outer wall of the stirring drum. The detection end of the level gauge penetrates the outer wall of the stirring drum and extends directly into the interior of the stirring drum. This is used to monitor the height of the food concentrate in real time and to promptly provide a control signal when the liquid level rises too high, thereby triggering a deceleration and retraction mechanism at the bottom layer.
[0010] Preferably, the high-speed stirring anti-overflow structure for food processing raw materials also includes a lid placed on top of the stirring drum. The outer wall of the lid has an exhaust hole, which is used to create a relatively isolated anti-splash environment inside the stirring drum when stirring the raw liquid and to continuously discharge excess gas to prevent excessive sealing pressure inside the drum.
[0011] Preferably, the inner wall of the bucket lid is rotatably connected to a connecting rod, and the outer wall of the connecting rod is fixedly connected to an annular defoaming plate. The annular defoaming plate rotates at high speed coaxially with the connecting rod, which is used to physically break up and eliminate a large number of bubbles generated during the high-speed mixing of raw materials, and further prevent overflow caused by the accumulation of large amounts of foam.
[0012] Preferably, the lower part of the outer wall of the connecting rod is provided with an external thread, and a second locking block is threadedly connected to the outer wall of the connecting rod. The inner wall of the second locking block is provided with an internal thread that mates with the external thread. The connecting rod and the second locking block are connected in an adjustable threaded manner through the external thread and the internal thread. This is used to dynamically change the exact height of the second locking block on the outer wall of the connecting rod according to different raw material quantities, so as to ensure that the best defoaming effect can be achieved at each liquid level.
[0013] Preferably, a locking block one is fixedly connected to the top of the transmission rod, and the locking block two is precisely engaged into the interior of the locking block one. The stable engagement drive structure from bottom to top ensures that the rotational power of the bottom layer can be smoothly transmitted to the defoaming mechanism at the top.
[0014] Preferably, the top end of the transmission rod and the inner wall of the first locking block are provided with a receiving groove, and the bottom end of the connecting rod extends downward into the receiving groove. This is used to conceal and store the excess length when the height of the connecting rod is adjusted downward, thereby avoiding mechanical interference during rotation and ensuring the smooth operation of the overall anti-overflow and defoaming mechanism.
[0015] This utility model has the following beneficial effects:
[0016] 1. This utility model solves the problem that the existing technology is prone to overflowing when the raw material liquid level rises too high due to centrifugal force during high-speed stirring in food processing by setting a liquid level gauge in conjunction with a drive motor and a stirring blade that is expanded by centrifugal force and pulled back by an elastic rope. It achieves the effect of automatically reducing the speed and stirring range when the liquid level exceeds the standard, so as to promote the liquid surface to calm down quickly and effectively prevent the raw material from overflowing.
[0017] 2. This utility model solves the problem in the prior art where food residue easily falls into the movable folding parts during operation, causing the retraction mechanism to jam and fail, by sliding a blocking ring in the storage tank and setting an elastic reset rod at its bottom in conjunction with the squeezing slope at the bottom of the stirring blade. It achieves the effect of automatically sealing the gap when the stirring blade is fully unfolded and smoothly pressing back to the bottom of the tank during retraction, thus ensuring the long-term smooth operation of the anti-overflow folding mechanism without jamming.
[0018] 3. This utility model solves the problems of foam overflow caused by a large number of bubbles generated during high-speed stirring and the inability of the top defoaming device to adaptively adjust the height of the top defoaming device according to the actual liquid level. It achieves smooth upward transmission of the bottom driving force, synchronous physical breaking of bubbles, and flexible adjustment of the height of the defoaming plate to ensure optimal defoaming and mixing at all liquid levels.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0029] Example:
[0030] Please refer to Figures 1 to 7This utility model provides a high-speed stirring anti-overflow structure for food processing raw materials, which aims to solve the problems in the prior art where food processing stirring equipment is prone to overflow due to centrifugal force and the generation of a large number of bubbles during high-speed stirring, and where moving folding parts are prone to getting stuck with raw material residue when shrinking, leading to mechanical jamming and failure.
[0031] Please refer to Figure 1 and Figure 2 The high-speed mixing and anti-overflow structure for food processing raw materials includes a base 1 and a mixing drum 2 fixedly connected to the top of the base 1. A drive motor 3 is fixedly connected to the inner wall of the base 1, and a transmission rod 4 is fixedly connected to the output end of the drive motor 3. The transmission rod 4 extends into the mixing drum 2. The base 1 serves as a sturdy support platform and mounting base for the entire device. The mixing drum 2 is used to hold and contain the food raw liquid that needs to be mixed and processed. The drive motor 3 provides basic rotational power for the operation of the entire device. The transmission rod 4 receives the rotational torque generated by the drive motor 3 and rotates inside the mixing drum 2 to drive the operation of subsequent mechanisms.
[0032] A rotating disk 6 is fixedly connected to the outer wall of the transmission rod 4. A receiving groove 10 is opened on the outer wall of the rotating disk 6. A rotating shaft 8 is rotatably connected to the outer wall of the rotating disk 6. A stirring blade 7 is fixedly connected to the outer wall of the rotating shaft 8. An elastic rope 9 is fixedly connected to the inner wall of the receiving groove 10. The end of the elastic rope 9 away from the inner wall of the receiving groove 10 is fixedly connected to the stirring blade 7. The rotating disk 6 is used to support the internal components and rotate synchronously with the transmission rod 4. The rotating shaft 8 is used to provide a fulcrum for the stirring blade 7 to expand outward and retract inward. When the stirring blade 7 is fully expanded outward under the action of high-speed centrifugal force, it can vigorously stir the raw materials inside the stirring drum 2 over a wide range. When the speed of the drive motor 3 is reduced, so that the centrifugal force is reduced, the elastic rope 9 can provide a pulling force to retract inward, so that the stirring blade 7 retracts into the receiving groove 10 and thus reduces the stirring range.
[0033] A blocking ring 20 is slidably connected to the inner wall of the storage tank 10. An elastic reset rod 21 is fixedly connected to the bottom of the blocking ring 20. The end of the elastic reset rod 21 away from the blocking ring 20 is fixedly connected to the inner wall of the storage tank 10. The blocking ring 20 is used to slide upward to fill the gap after the stirring blade 7 is unfolded by centrifugal force and leaves the storage tank 10, thereby completely preventing food residue from mixing into the storage tank 10. The elastic reset rod 21 is used to provide a continuous elastic lifting thrust for the blocking ring 20 to slide upward to seal the gap, and to undergo elastic deformation under pressure when the stirring blade 7 retracts, thereby ensuring the stable realization of the mechanical anti-overflow and anti-jamming functions.
[0034] It also includes a level gauge 5, and the level gauge 5 and the aforementioned stirring tank 2 form a specific structural fit and connection relationship, please refer to... Figure 1 and Figure 2The level gauge 5 is fixedly connected to the outer wall of the mixing drum 2. The detection end of the level gauge 5 penetrates the outer wall of the mixing drum 2 and extends into the interior of the mixing drum 2. The function of the level gauge 5 is to monitor the height of the food raw liquid inside the mixing drum 2 in real time and to send a feedback signal to control the drive motor 3 to reduce the speed when the liquid level is too high. This reduces the centrifugal force on the stirring blade 7 and causes it to retract into the receiving tank 10 under the tension of the elastic rope 9, thereby reducing the stirring range of the stirring blade 7 and preventing the liquid level inside the mixing drum 2 from overflowing due to excessively high liquid level.
[0035] A lid 13 is placed on the top of the mixing drum 2. A vent 14 is provided on the outer wall of the lid 13. The lid 13 is used to create a relatively isolated environment inside the mixing drum 2 to prevent splashing of the raw liquid when it is being stirred. The vent 14 is used to prevent excessive air pressure inside the mixing drum 2 and to balance the air pressure.
[0036] A connecting rod 15 is rotatably connected to the inner wall of the bucket lid 13. An annular defoaming plate 16 is fixedly connected to the outer wall of the connecting rod 15. An external thread 17 is provided in the lower middle part of the outer wall of the connecting rod 15. A locking block 18 is threadedly connected to the outer wall of the connecting rod 15. An internal thread 19 is provided on the inner wall of the locking block 18 to cooperate with the external thread 17. The connecting rod 15 and the locking block 18 are threadedly connected through the external thread 17 and the internal thread 19. The function of the annular defoaming plate 16 is to physically break up and eliminate the bubbles generated during the mixing of raw materials when it rotates at high speed with the connecting rod 15 to prevent foam overflow. The function of the structure of the external thread 17 and the internal thread 19 is to adjust the height of the locking block 18 on the outer wall of the connecting rod 15 by rotating the connecting rod 15, thereby realizing the dynamic adjustment of the height position of the annular defoaming plate 16 to ensure the best defoaming and mixing effect under different liquid levels.
[0037] A locking block 11 is fixedly connected to the top of the transmission rod 4, and a locking block 2 18 is inserted into the inside of the locking block 11. The top of the transmission rod 4 and the inner wall of the locking block 11 are provided with a receiving groove 12. The bottom end face of the connecting rod 15 extends into the receiving groove 12. The locking structure of the locking block 11 and the locking block 2 18 ensures that the rotational power of the transmission rod 4 can be stably transmitted from bottom to top to the connecting rod 15 and drive the annular defoaming plate 16 to rotate synchronously. The function of the receiving groove 12 is to store the bottom part of the connecting rod 15 when adjusting the height of the connecting rod 15 to avoid mechanical interference, thereby ensuring the smooth operation of the overall anti-overflow defoaming mechanism.
[0038] A lid 13 is placed on top of the mixing drum 2. The outer wall of the lid 13 has an exhaust hole 14. In order to physically break up and eliminate the bubbles generated by high-speed rotation during the mixing of the original liquid and prevent foam overflow, a connecting rod 15 is rotatably connected to the inner wall of the lid 13. An annular defoaming plate 16 is fixedly connected to the outer wall of the connecting rod 15. The annular defoaming plate 16 rotates at high speed coaxially inside the mixing drum 2 along with the connecting rod 15, thereby quickly breaking up and eliminating the bubbles on the liquid surface.
[0039] The lower middle part of the outer wall of the connecting rod 15 has an external thread 17. The outer wall of the connecting rod 15 is threadedly connected to a second locking block 18. The inner wall of the second locking block 18 has an internal thread 19 that mates with the external thread 17. The connecting rod 15 and the second locking block 18 are threadedly connected through the external thread 17 and the internal thread 19. By manually rotating the connecting rod 15, the exact position of the second locking block 18 on the outer wall of the connecting rod 15 can be changed by utilizing the threaded engagement of the external thread 17 and the internal thread 19.
[0040] A locking block 11 is fixedly connected to the top of the transmission rod 4. A locking block 2 18 is inserted into the inside of the locking block 11. The top of the transmission rod 4 and the inner wall of the locking block 11 are provided with a receiving groove 12. The bottom end face of the connecting rod 15 extends into the receiving groove 12. The locking block 2 18 is precisely inserted into the inside of the locking block 11 to form a stable locking drive structure, thereby ensuring that the power of the bottom drive structure is smoothly transmitted to the top defoaming mechanism.
[0041] A level gauge 5 is fixedly connected to the outer wall of the mixing drum 2. The detection end of the level gauge 5 penetrates the outer wall of the mixing drum 2 and extends directly into the interior of the mixing drum 2. The detection end of the level gauge 5 is in direct contact with the food raw liquid inside and generates a control signal when it detects that the liquid level exceeds the standard. This signal then guides the relevant drive components to adjust the speed, thereby cooperating with the bottom centrifugal folding stirring mechanism to complete the speed reduction and anti-overflow closed loop.
[0042] A drive motor 3 is fixedly connected to the inner wall of the base 1. A transmission rod 4 is fixedly connected to the output end of the drive motor 3. A rotating disk 6 is fixedly connected to the outer wall of the transmission rod 4. A rotating shaft 8 is rotatably connected to the outer wall of the rotating disk 6. A collection groove 10 is opened on the outer wall of the rotating disk 6. An elastic rope 9 is fixedly connected to the inner wall of the collection groove 10. The end of the elastic rope 9 away from the inner wall of the collection groove 10 is fixedly connected to the stirring blade 7. A blocking ring 20 is slidably connected to the inner wall of the collection groove 10. An elastic reset rod 21 is fixedly connected to the bottom of the blocking ring 20. The end of the elastic reset rod 21 away from the blocking ring 20 is fixedly connected to the inner wall of the collection groove 10. Under the lifting action of the elastic reset rod 21, the blocking ring 20 slides upward to fill the gap of the collection groove 10, completely preventing food residue from mixing into the interior and ensuring the long-term stability of the mechanical anti-overflow and anti-jamming functions.
[0043] Working principle: When the device is used for food processing and mixing, the base 1 provides stable support for the overall operation. By pouring the raw materials into the mixing drum 2 and starting the drive motor 3 on the inner wall of the base 1, the drive motor 3 drives the transmission rod 4 to rotate counterclockwise inside the mixing drum 2, thus providing the basic driving force for subsequent mixing. The transmission rod 4 drives the rotating disk 6 to rotate synchronously. Since the outer wall of the rotating disk 6 is rotatably connected to the rotating shaft 8 and the outer wall of the rotating shaft 8 is fixedly connected to the stirring blade 7, the high-speed rotation of the rotating disk 6 causes the stirring blade 7 stored in the storage tank 10 to be subjected to a strong outward centrifugal force, thereby overcoming the tension of the elastic rope 9 and unfolding outward around the rotating shaft 8. The stirring blade 7 is fully unfolded inside the mixing drum 2 to vigorously stir the food raw materials in a wide range. After the stirring blade 7 is fully unfolded and leaves the storage tank 10, the blocking ring 20 slides upward under the lifting thrust of the elastic reset rod 21 until the gap between the stirring blade 7 and the storage tank 10 is completely filled and sealed, thereby preventing food residue from mixing into the storage tank 10 and causing the stirring blade 7 to be stuck and unable to retract smoothly.
[0044] When the detection end of the level gauge 5 comes into contact with the churning liquid surface, the equipment determines that the liquid level inside the stirring drum 2 is too high and there is a risk of overflow. Therefore, it controls the drive motor 3 to reduce its speed. The reduction in the speed of the drive motor 3 causes the centrifugal force on the stirring blade 7 to decrease significantly. Under the continuous contraction and tension of the elastic rope 9, the stirring blade 7 retracts back into the receiving tank 10. The inward retraction of the stirring blade 7 reduces the range of agitation of the liquid, thereby directly reducing the intensity of the movement of the raw materials inside the stirring drum 2. The liquid surface of the raw materials then quickly calms down, ultimately preventing the liquid level inside the stirring drum 2 from overflowing due to excessively high liquid level.
[0045] When stirring the stock solution, placing the lid 13 on top creates a relatively isolated environment inside the stirring drum 2 to prevent splashing. The vent 14 continuously discharges excess gas to prevent excessive sealing pressure inside the stirring drum 2. Before covering the stirring drum 2 with the lid 13, manually rotate the connecting rod 15 to adjust the height of the second locking block 18 on the outer wall of the connecting rod 15 by using the external thread 17 and the internal thread 19. Then, precisely insert the second locking block 18 downward into the first locking block 11 and hide the bottom end of the connecting rod 15 in the receiving groove 12 to complete the height self-adjustment of the annular defoaming plate 16. When the drive motor 3 drives the transmission rod 4 to rotate at high speed, the power is smoothly transmitted from bottom to top to the connecting rod 15 through the stable engagement of the first locking block 11 and the second locking block 18. The connecting rod 15 drives the annular defoaming plate 16 to rotate synchronously and coaxially at high speed, thereby physically breaking up and eliminating the bubbles generated during the high-speed stirring of the raw materials, thus ensuring the best defoaming and anti-overflow mixing effect.
