Description

Technical Field

[0001] This invention relates to the field of mixing equipment technology, specifically to an oral liquid mixing equipment with adaptive frequency conversion stirring. Background Technology

[0002] In the production of oral liquids, the uniformity of raw material mixing directly determines product quality and efficacy stability. The mixing performance of the mixing equipment is a core technical aspect. Currently, the mainstream oral liquid mixing equipment in the industry mainly adopts single-dimensional mixing and relies heavily on uniform speed motion. Some equipment requires multiple variable frequency motors and complex control systems to achieve multi-action coordination. In practical applications, this has gradually revealed many technical limitations, the specific problems of which are as follows:

[0003] Existing oral liquid mixing equipment generally adopts a single structural design of single-shaft rotary stirring or fixed frame shearing stirring. The movement trajectory of the stirring components is mostly fixed circular or linear reciprocating, which cannot create all-round, multi-dimensional disturbance to the material. In the production of oral liquids, in order to ensure efficacy, trace functional ingredients such as vitamins, minerals, and plant extracts are often added. These ingredients usually have the characteristics of low density, easy agglomeration, or poor compatibility with the base material. In the process of single-dimensional uniform speed stirring, the material only flows in a fixed direction, which easily forms flow dead zones.

[0004] Based on this, the present invention provides an oral liquid mixing device with adaptive variable frequency stirring to solve the problems mentioned in the background art. Summary of the Invention

The two stirring components are respectively disposed on the inner side of the two stirring cylinders.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. This invention utilizes a multi-system linkage of vertical and horizontal variable frequency movement, counter-rotation of the tilting frame and inner shaft, reciprocating rocking of the tilting drum, symmetrical shearing of the stirring shaft, and circumferential stirring of the rotating drum to form a comprehensive, dead-angle-free stirring pattern. This is fundamentally different from the single-dimensional stirring of existing technologies. The drive motor drives the first variable frequency wheel to achieve slow, medium, and fast stepped movement of the vertical slide through tooth segments with different center angles. Simultaneously, the second variable frequency wheel is linked by a synchronous toothed belt to drive the horizontal variable frequency movement of the transverse slide. The superposition of these two mechanisms creates a complex spatial trajectory for the stirring components, breaking the inertia of material flow. The tilting frame and inner shaft are symmetrically meshed by synchronous bevel gears. The combined coaxial reverse rotation, along with the intermittent meshing of the incomplete gear and the rocking gear in the shaking mechanism, drives the tilting drum to reciprocate around the hinge axis, avoiding the generation of flow dead zones. The two stirring shafts in the inner drum are driven to rotate in opposite directions through the core shaft, forming opposing shear forces that directly act on the agglomerates of trace components. Meanwhile, the rotating drums at both ends simultaneously stir circumferentially, further accelerating material convection. This multi-dimensional synergistic action reduces the dispersion deviation of trace components without increasing the rotation speed, effectively protecting the structure of heat-sensitive components in the oral liquid. It solves the problem that the single stirring dimension in the existing technology cannot simultaneously ensure dispersion uniformity and component stability.

[0018] 2. This invention abandons the existing technology of relying on variable frequency motors for speed regulation. Instead, it achieves adaptive frequency conversion through a purely mechanical structure design, possessing both innovative and reliable advantages. The first variable frequency tooth segment on the first variable frequency wheel, with three center angles increasing by 20° sequentially, alternately meshes with the vertical tooth plate. Combined with the vertical spring reset, this dynamically changes the upward speed of the vertical slide. The second variable frequency tooth segment on the second variable frequency wheel, with a center angle difference of 30°, drives the transverse slide to achieve differentiated horizontal movement. Furthermore, the tensioning element, through the elastic cooperation between the tensioning spring and the tensioning wheel, ensures that the synchronous toothed belt remains taut throughout the slide movement, resulting in lossless power transmission. This mechanical frequency conversion mode keeps the material in a non-uniform speed disturbance state during the stirring process, effectively disrupting the stratification conditions. Especially for base materials and functional ingredients with large viscosity differences in oral liquid production, it can prevent high-density components from depositing at the bottom, solving the inherent defect of uneven mixing caused by material stratification in existing uniform speed stirring equipment.

[0032] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0033] The present invention provides the following preferred embodiments.

[0034] like Figure 1-11 As shown, the oral liquid mixing equipment with adaptive frequency conversion stirring includes a frame 1 and a drive motor 2. The drive motor 2 is fixedly installed on the frame 1. A protective baffle 12 is installed on the frame 1, and a PLC controller 13 is installed on the protective baffle 12.

[0035] A vertical slide block 4 is slidably connected to the frame 1, and a first frequency converter is connected to the output shaft end of the transmission motor 2 to drive the vertical slide block 4 to reciprocate up and down with frequency conversion.

[0036] The first frequency converter includes a first frequency converter wheel 14 mounted on the output shaft of the drive motor 2. The first frequency converter wheel 14 has three first frequency converter tooth segments 15 and a first idle segment 16 alternately arranged along the circumferential direction. A vertical tooth plate 17 is mounted on the vertical slide 4. The three first frequency converter tooth segments 15 alternately mesh with the vertical tooth plate 17. In the clockwise direction, the central angles of the three first frequency converter tooth segments 15 increase by 20° in turn. The central angles of the three first idle segments 16 are the same.

[0037] The sum of the center angles of the three first frequency conversion tooth segments 15 and the three first idle segments 16 is 360°;

[0038] In a preferred embodiment, the center angles of the three first frequency conversion tooth segments 15 in the clockwise direction are 40°, 60° and 80° respectively, and the center angles of the three first idle segments 16 are all 60°.

[0039] A set of vertical springs 18 are installed on the bottom surface of the vertical slide 4, and the bottom end of each vertical spring 18 is fixedly connected to the frame 1.

[0040] By alternating meshing of the first frequency conversion tooth segment 15 with three center angles increasing by 20° on the first frequency conversion wheel 14 and the vertical tooth plate 17, combined with the first idle segment 16 with the same center angle, the vertical slide block 4 can achieve slow, medium and fast stepped frequency conversion vertical reciprocating motion.

[0041] The reset action of the vertical spring 18 drives the slide to fall back smoothly, forming a reciprocating frequency conversion vertical motion trajectory;

[0042] This structure eliminates the need for an additional variable frequency motor, achieving adaptive frequency conversion solely through the angle design of the mechanical tooth segments. This not only simplifies the transmission system but also improves the uniformity of mixing by changing the vertical height and speed of material mixing, thus avoiding the problems of material stratification and sedimentation in traditional uniform mixing.

[0043] A horizontal slide 5 is slidably connected to the vertical slide 4, and a second frequency converter is provided to drive the horizontal slide 5 to reciprocate horizontally.

[0044] The second frequency converter includes a second frequency converter wheel 19 and a belt shaft 20 rotatably connected to the vertical slide block 4. Both the belt shaft 20 and the second frequency converter wheel 19 are equipped with first bevel gears, and the two first bevel gears mesh orthogonally.

[0045] The second frequency conversion wheel 19 is alternately provided with two second frequency conversion tooth segments 21 and two idle segments 22 along the circumferential direction. The central angles corresponding to the two second frequency conversion tooth segments 21 differ by 30°, and the central angles corresponding to the two second idle segments 22 are the same.

[0046] The sum of the center angles of the two second frequency conversion tooth sections 21 and the two second idle sections 22 is 360°;

[0047] In a preferred embodiment, the center angles of the two second frequency conversion tooth segments 21 are 50° and 70°, respectively;

[0048] The central angles corresponding to the two first empty segments 16 are both 120°;

[0049] A flat toothed plate 23 is installed on the transverse slide 5. Two second frequency conversion tooth segments 21 alternately mesh with the flat toothed plate 23. A set of flat springs 40 is installed on the side of the transverse slide 5. The other end of each flat spring 40 is fixedly connected to the vertical slide 4. A first synchronous toothed belt is connected between the output shaft end of the drive motor 2 and the belt shaft 20.

[0050] The shaft 20 drives the second variable frequency wheel 19 to rotate through the first bevel gear. By utilizing the alternating meshing of the second variable frequency tooth segment 21 with two center angles differing by 30° and the flat tooth plate 23, and in conjunction with the reset function of the flat spring 40, the transverse slide 5 can achieve horizontal reciprocating variable frequency motion at different speeds.

[0051] At the same time, the first synchronous toothed belt can stably transmit the power of the drive motor 2, ensuring the coordination of lateral and vertical movements;

[0052] This design achieves horizontal adaptive frequency conversion through mechanical structure. When superimposed with vertical frequency conversion motion, it can drive the stirring component to form a complex spatial motion trajectory, breaking the flow inertia of the material and further enhancing the mixing effect. It is especially suitable for mixing raw materials with large viscosity differences in oral liquid production.

[0053] The frame 1 is equipped with a tensioning element to tension the first synchronous toothed belt;

[0054] The tensioning component includes a tensioning slider 24 slidably connected to the frame 1, a tensioning spring 25 mounted on the bottom surface of the tensioning slider 24, the other end of the tensioning spring 25 being fixedly connected to the frame 1, and a tensioning wheel 26 rotatably mounted on the tensioning slider 24, which is connected to the first synchronous toothed belt drive.

[0055] The tension spring 25 pushes the tension slider 24 upward through elastic force, so that the tension wheel 26 is always in close contact with the first synchronous toothed belt and applies a stable tension force. When the vertical slide 4 moves up and down, causing the length of the synchronous toothed belt to change dynamically, the tension wheel 26 can adjust its position adaptively through the sliding of the slider to avoid the synchronous toothed belt from becoming loose or slipping, and to ensure the stability and accuracy of power transmission.

[0056] This structure eliminates the need for manual adjustment, enabling automatic compensation of the synchronous toothed belt tension, reducing equipment maintenance costs, and ensuring the accuracy of the lateral carriage 5 frequency conversion motion.

[0057] The transverse carriage 5 is equipped with a tilting frame 6 and an inner shaft 7 that are driven by a transmission motor 2 and rotate in opposite directions on the same axis.

[0058] A hollow shaft 27 is rotatably mounted on the vertical slide 4. The hollow shaft 27 is connected to the first synchronous toothed belt drive. A flower shaft section 28 is fixedly provided at the tail of the inner shaft 7. The flower shaft section 28 is rotatably connected to the transverse slide 5 through a bearing. A hollow groove with open ends and slidably connected to the flower shaft section 28 is fixedly opened inside the hollow shaft 27. A synchronous shaft 29 is rotatably mounted on the transverse slide 5. A synchronous bevel gear is installed on the synchronous shaft 29. A second bevel gear is installed on both the tilting frame 6 and the inner shaft 7. Both second bevel gears are connected to the synchronous bevel gear drive.

[0059] The cross-sections of the hollow groove and the flower shaft section 28 are both regular hexagons. The two second bevel gears are respectively set on both sides of the synchronous bevel gear, and the two second bevel gears are symmetrically arranged.

[0060] The two second bevel gears are of the same specification;

[0061] The hollow hexagonal groove, in conjunction with the flower shaft section 28, can both transmit power from the hollow shaft 27 to the inner shaft 7 and allow the inner shaft 7 to slide horizontally with the transverse slide 5, thus solving the technical problem of simultaneous motion transmission and position movement.

[0062] The synchronous bevel gear on the synchronous shaft 29 meshes symmetrically with the second bevel gear on the tilting frame 6 and the inner shaft 7, which can convert the same power source into the coaxial reverse rotational motion of the tilting frame 6 and the inner shaft 7.

[0063] This transmission design is not only compact, but also drives the tilting drum 8 and the internal stirring components to move in opposite directions through the reverse rotation of the tilting frame 6 and the inner shaft 7, which intensifies the shearing and convection of the material and greatly improves the mixing efficiency.

[0064] A tilting cylinder 8 is rotatably mounted on the tilting frame 6, and a shaking mechanism is provided on the tilting frame 6 to drive the tilting cylinder 8 to reciprocate. A spindle 9 is rotatably mounted on the tilting cylinder 8, and an inner cylinder 41 is fixedly mounted on it. Two symmetrically arranged stirring components that are linked with the spindle 9 are rotatably mounted on the inner cylinder 41. Both ends of the tilting cylinder 8 are rotatably mounted with a stirring drum 10 driven by a transmission motor 2, and one end of each of the two stirring drums 10 is connected to a material valve 11.

[0065] The shaking mechanism includes a left gear shaft 39 and an intermittent shaft 30 rotatably mounted on the tilting frame 6. A third bevel gear is mounted on both the left gear shaft 39 and the inner shaft 7. The two third bevel gears mesh orthogonally. A hinge shaft 31 and a hollow rotating sleeve 32 are symmetrically mounted on the tilting cylinder 8. A toothed sleeve 33 is rotatably mounted on the hinge shaft 31. A second synchronous toothed belt is driven and connected to the left gear shaft 39. The intermittent shaft 30 and the hollow rotating sleeve 32 are both driven and connected to the third synchronous toothed belt. An incomplete gear 34 is mounted on the intermittent shaft 30. A rocking gear 35 that meshes with the incomplete gear 34 is mounted on the hinge shaft 31. A driving bevel gear is mounted on the toothed sleeve 33. A passive bevel gear ring 36 that is driven and connected to the driving bevel gear is mounted on both stirring cylinders 10.

[0066] The center angle corresponding to the effective meshing section on the incomplete gear 34 is 45°, and the radius of the incomplete gear 34 is the same as that of the rocking gear 35.

[0067] The inner shaft 7 drives the left gear shaft 39 to rotate via the third bevel gear, and then the second synchronous gear belt and the third synchronous gear belt link the intermittent shaft 30 and the hollow rotating sleeve 32.

[0068] The incomplete gear 34 intermittently meshes with the rocking gear 35, and in conjunction with the transmission action of the gear sleeve 33, enables the tilting cylinder 8 to reciprocate around the hinge shaft 31.

[0069] Among them, the 45° effective meshing section and equal radius design of the incomplete gear 34 can accurately control the shaking angle and frequency, and avoid excessive shaking of the tipping drum 8, which would cause material to splash.

[0070] This mechanism converts rotational power into reciprocating shaking motion, causing the material inside the tipping drum 8 to continuously change its posture, avoiding local dead zones, and forming a compound action of 360° flipping, reciprocating shaking and stirring with the mixing components, further optimizing the uniformity of mixing.

[0071] It also includes a right gear shaft 37 rotatably connected to the tilting frame 6, a fourth bevel gear is mounted on the right gear shaft 37, the fourth bevel gear is connected to the third bevel gear on the inner shaft 7, the spindle 9 is rotatably connected to the hollow rotating sleeve 32 through a bearing, and a fourth synchronous toothed belt is connected between the right gear shaft 37 and the spindle 9.

[0072] Both stirring components include a stirring shaft 38, which is rotatably mounted on the inner cylinder 41. A fifth bevel gear is mounted on both the stirring shaft 38 and the spindle 9. The two fifth bevel gears mesh orthogonally. Multiple sets of stirring rods 3 are mounted on the stirring shaft 38. The two stirring components are respectively located inside the two swirling cylinders 10.

[0073] The inner shaft 7 drives the right gear shaft 37 to rotate via the fourth bevel gear, and then drives the spindle 9 to rotate via the fourth synchronous gear belt;

[0074] The spindle 9 drives two symmetrical stirring shafts 38 to rotate in opposite directions via the fifth bevel gear, and the stirring shafts 38 are located inside the stirring drum 10, so they can directly act on the material entering the inner drum 41.

[0075] This transmission design enables a single power source to drive the coordinated movement of multiple components. The symmetrical rotation of the two stirring pieces can generate opposing shear forces. Combined with the rotation of the stirring drum 10 and the shaking of the tilting drum 8, a multi-dimensional stirring system with inner, outer, circumferential, and axial dimensions is constructed, which effectively solves the problem of uneven dispersion of trace components in oral liquid production and ensures the stability of product quality.

[0076] The working principle of this invention is as follows: Before operation, the raw materials for the oral liquid to be mixed are injected into the inside of the turning cylinder 8. After the raw materials are injected, the injection valve 11 is closed. During operation, the transmission motor 2 drives the first variable frequency wheel 14 to rotate. The first variable frequency tooth segment 15, whose three center angles increase by 20° in sequence, alternately meshes with the vertical tooth plate 17. With the help of the vertical spring 18 to reset, it drives the vertical slide 4 to achieve slow, medium and fast stepped vertical variable frequency motion.

[0077] Meanwhile, the drive motor 2 drives the belt shaft 20 to rotate through the first synchronous toothed belt. The belt shaft 20 is linked to the second frequency conversion wheel 19 through the first bevel gear. The second frequency conversion tooth segment 21 with a center angle difference of 30° meshes with the flat tooth plate 23 and is reset by the horizontal spring 40, realizing the horizontal frequency conversion movement of the transverse slide 5. The tensioning member pushes the tensioning wheel 26 through the tensioning spring 25 to adaptively tension the synchronous toothed belt, ensuring stable power transmission. At this time, the vertical and horizontal frequency conversion movements are superimposed, providing a basis for the complex spatial movement of the subsequent stirring components.

[0078] In terms of power transmission, the first synchronous toothed belt simultaneously drives the hollow shaft 27 to rotate. The cooperation between the regular hexagonal hollow groove and the flower shaft section 28 enables the inner shaft 7 to obtain power while moving with the transverse slide 5. The inner shaft 7 drives the tilting frame 6 to rotate in the opposite direction to the inner shaft 7 through the meshing of the synchronous bevel gear and the second bevel gear on both sides.

[0079] The inner shaft 7 then drives the left gear shaft 39 and the right gear shaft 37 respectively through the third bevel gear. The left gear shaft 39 is linked to the intermittent shaft 30 and the hollow rotating sleeve 32 through the second synchronous tooth belt and the third synchronous tooth belt. The intermittent meshing of the incomplete gear 34 and the rocking gear 35 causes the tilting cylinder 8 to reciprocate around the hinge shaft 31. The right gear shaft 37 drives the core shaft 9 to rotate through the fourth synchronous tooth belt. The core shaft 9 drives the two symmetrical stirring shafts 38 to rotate in opposite directions through the fifth bevel gear. At the same time, the stirring cylinders 10 at both ends of the tilting cylinder 8 rotate synchronously. Finally, a multi-dimensional coordinated action is formed, which includes vertical and horizontal frequency conversion movement, reverse rotation of the tilting frame 6 and the inner shaft 7, reciprocating rocking of the tilting cylinder 8, symmetrical shearing of the stirring shaft 38, and circumferential stirring of the stirring cylinder 10.

[0080] The key to achieving synchronous power transmission and position movement is the hexagonal fit between the hollow groove and the flower shaft section 28. Its necessity lies in solving the contradiction that motion and power cannot be taken into account in the traditional transmission structure. If a circular fit is used, there will be free spin and slippage. If a key connection is used, horizontal sliding cannot be achieved. This structure is directly related to the coordination between the frequency conversion motion of the transverse slide 5 and the rotational motion of the tilting frame 6 and the inner shaft 7, ensuring that the actions of each component do not interfere with each other and that the power transmission is lossless.

[0081] The aforementioned multi-system linkage ultimately solves the technical problems of existing oral liquid mixing equipment, such as uneven dispersion of trace components due to single stirring dimension, material stratification caused by uniform motion, and complex control and high maintenance costs of multiple power sources. By achieving an organic combination of adaptive frequency conversion and multi-dimensional stirring through mechanical structure, efficient mixing can be achieved without multiple frequency conversion motors, significantly improving the uniformity and stability of oral liquid raw material mixing.

[0082] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
