Double-shaft paddle mixing structure for chicken essence production

Abstract

This invention relates to the field of chicken bouillon production technology and discloses a dual-shaft paddle-type mixing structure for chicken bouillon production. The structure includes a shell, with two symmetrically arranged rods rotatably connected to the inner side of the shell. Both rods have evenly distributed crossbars inserted into their inner sides. The angle of the dual-shaft stirring components is independently adjustable to adapt to different chicken bouillon formulations. A rocker wheel drives a worm gear and screw, which in turn moves the threaded ring, support rod, and collar axially. The rack on the moving plate drives the stirring components at the ends of each crossbar to rotate around their own axis. Because the moving plates and racks within the two rods are symmetrically designed, the stirring components on the two rods rotate in opposite directions under the same external force, creating opposing pushing and shearing forces. The operator can flexibly adjust the tilt angle of the stirring components according to the particle size, moisture content, and flowability of the chicken bouillon raw materials, ensuring the mixer is always in optimal working condition and meeting diverse production needs.

Description

Technical Field

[0001] This invention belongs to the field of chicken essence production technology, and specifically relates to a dual-shaft paddle-type mixing structure for chicken essence production. Background Technology

[0002] In the production of chicken bouillon, various powdered raw materials such as salt, sugar, monosodium glutamate (MSG), maltodextrin, and spices need to be thoroughly mixed according to the formula ratio. The twin-shaft paddle mixer has become the mainstream mixing equipment in the chicken bouillon industry due to its high mixing uniformity, high efficiency, and wide adaptability to materials. This equipment has multiple sets of paddles installed on its two stirring shafts. During operation, the two shafts rotate in opposite directions, and the paddles generate shearing, scattering, and convection effects on the materials, achieving uniform dispersion of each component.

[0003] However, different chicken bouillon formulations have significantly different requirements for the mixing process: for example, chicken bouillon with coarser particles requires a larger blade pushing angle to enhance axial circulation, while formulations with high sugar content and easy adhesion require a smaller attack angle to reduce compression and clumping; materials with high moisture content require the blades to turn at a gentler angle to avoid local overheating.

[0004] However, the blade angles of most existing twin-shaft paddle mixers are fixed—the blades are rigidly fixed to the mixing shaft by welding or bolts, making it impossible to adjust them according to the characteristics of the raw materials during production. When switching between different chicken bouillon formulas, fixed-angle blades often cannot simultaneously ensure mixing uniformity and material protection: an excessively large angle can lead to excessive material breakage, resulting in powder or agglomeration; an excessively small angle results in long mixing cycles, high energy consumption, and the formation of mixing dead zones at both ends of the mixing shaft, affecting batch consistency. Although some equipment allows for blade disassembly, shim angle adjustment, and reinstallation after shutdown, the operation is cumbersome, time-consuming, and cannot accurately quantify the deflection consistency of different blades, so it is rarely used in actual production. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dual-shaft paddle-type mixing structure for chicken essence production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dual-shaft paddle-type mixing structure for chicken essence production, including a shell, wherein rod one and rod two are rotatably connected to the inner side of the shell respectively, and uniformly distributed crossbars are inserted into the inner side of rod one and rod two, and the crossbars of rod one and rod two are arranged in an alternating manner. Multiple crossbars are connected through rod one and rod two, and are rotatably connected to rod one and rod two. Both ends of each crossbar are fitted with symmetrically arranged stirring components, and the stirring components on rod one and rod two are designed in opposite directions. Gears are coaxially fixedly sleeved on the surface of each crossbar, and multiple gears are located inside rod one and rod two respectively. The surfaces of the gears are meshed with racks.

[0007] Preferably, the inner sides of both rod one and rod two are provided with shift plates, the surfaces of the gears are meshed with racks, and two adjacent racks are engaged with the shift plates. The shift plates and racks located on the inner sides of rod one and rod two are symmetrically designed. This design will enable the two racks to drive the two gears to rotate in opposite directions when moving in the same direction.

[0008] Preferably, a slide bar is snapped onto the side of the moving plate opposite to the rack, and sliding grooves are provided on the inner sides of both rod one and rod two, and the sliding grooves are used in sliding cooperation with the slide bar. The sliding connection between the sliding groove and the slide bar cooperates with the moving plate to guide its movement.

[0009] Preferably, one end of the moving plate is snapped with a moving rod, and the two moving rods pass through the outer sides of rod one and rod two respectively, and the moving rods are coaxially arranged with rod one and rod two respectively.

[0010] Preferably, the surface of the moving rod is fitted with symmetrically arranged snap-fit ​​strips, and one end of both rod one and rod two are provided with snap-fit ​​grooves. The sliding cooperation between the snap-fit ​​grooves and the snap-fit ​​strips will provide movement guidance for the moving rod.

[0011] Preferably, the ends of the two moving rods away from rod one and rod two are each rotatably fitted with collars, and the surfaces of the two collars are each fitted with symmetrically arranged support rods.

[0012] Preferably, a threaded ring is snapped together between the two support rods, and a screw is coaxially inserted into the inner side of the threaded ring. The screw and the threaded ring are threaded together, and the rotation of the screw will cause the threaded ring to move along its axial direction.

[0013] Preferably, one end of the screw extends through the inner side of the housing and is rotatably connected to the housing, and a worm gear is coaxially fixedly sleeved on the end of the screw located inside the housing.

[0014] Preferably, the surface of the worm gear is engaged with a worm, and one end of the worm passes through the outer side of the housing and is coaxially fixedly fitted with a rocker wheel.

[0015] In summary, the present invention has the following beneficial effects: 1. This invention features independently adjustable angles for the dual-shaft mixing components, adapting to different chicken bouillon formulation requirements. A rocker wheel drives a worm gear and screw, which in turn moves the threaded ring, support rod, and collar axially. The rack on the transfer plate then drives the mixing components at the ends of each crossbar to rotate around their own axis. Because the transfer plates and racks within the two rods are symmetrically designed, the mixing components on the two rods rotate in opposite directions under the same external force, creating opposing pushing and shearing forces. The operator can flexibly adjust the tilt angle of the mixing components according to the particle size, moisture content, and flowability of the chicken bouillon raw materials, ensuring the mixer is always in optimal working condition and meeting diverse production needs. 2. The opposite-angle stirring of this invention generates a complex flow field, eliminates mixing dead zones, and improves uniformity. The stirring elements on rod one and rod two are arranged at opposite angles, and when the dual shafts rotate, they push and shear the material in opposite directions. The material forms complex convection, eddies, and axial circulation in the casing, which effectively avoids mixing dead zones and significantly improves the dispersion uniformity and mixing efficiency of each component (salt, sugar, monosodium glutamate, spices, etc.) in chicken essence powder, ensuring batch consistency of products. 3. This invention features a worm gear self-locking and manual adjustment mechanism, making operation labor-saving and maintaining a stable angle. The worm gear drive for the screw component has a large reduction ratio and reverse self-locking characteristics. After adjustment, the angle of the stirring component remains stable and will not change due to material resistance or equipment vibration. Operators only need to rotate the rocker wheel to achieve stepless adjustment without stopping the machine for disassembly and assembly. This simplifies operation, saves effort, and improves the flexibility of the production line and equipment safety. 4. The multi-stage guiding structure of this invention ensures smooth transmission and improves adjustment accuracy and reliability. The moving plate slides through a sliding groove via a slide bar, and the moving rod slides through a locking strip and a locking groove. This dual guidance ensures that the moving plate and rack do not deflect or jam during movement, and the rack and gear mesh precisely, thus ensuring synchronous and consistent angle adjustment of each stirring component. This design reduces wear on transmission components and improves the repeatability and long-term reliability of the adjustment mechanism. Attached Figure Description

[0018] To make the technical means, creative features, achieved objectives, and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this invention and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.

[0019] Specific embodiments of the present invention are described below with reference to the accompanying drawings: Example: refer to Figures 1-5 A dual-shaft paddle-type mixing structure for chicken essence production includes an outer shell 1. The inner side of the outer shell 1 is rotatably connected to two rods 101 and 102 arranged symmetrically. The inner sides of the rods 101 and 102 are each inserted with a uniformly distributed crossbar 103, and the crossbars 103 of the rods 101 and 102 are arranged in an alternating manner. Multiple crossbars 103 pass through rod 101 and rod 202 and are rotatably connected to rod 101 and rod 202. Both ends of the crossbars 103 are fitted with symmetrically arranged stirring components 104, and the stirring components 104 on rod 101 and rod 202 are designed in opposite directions. Gears 2 are coaxially fixedly sleeved on the surface of the crossbars 103, and multiple gears 2 are located inside rod 101 and rod 202 respectively. The surfaces of the gears 2 are meshed with racks 3.

[0020] Specifically, the angle of the dual-shaft agitator 104 in this invention is independently adjustable to adapt to different chicken bouillon formulation requirements. The rocker wheel 9 drives the worm gear 8, worm 801, and screw 701, which in turn drives the threaded ring 7, support rod 601, and collar 6 to move the shift rod 5 axially. This movement is then driven by the rack 3 on the shift plate 4, which in turn drives the agitators 104 at the ends of each crossbar 103 to rotate around their own axes. Because the shift plates 4 and racks 3 within the two rods are symmetrically designed, the agitators 104 on the two rods rotate in opposite directions under the same external force, thus creating opposing pushing and shearing forces. The operator can flexibly adjust the tilt angle of the agitator 104 according to the particle size, moisture content, and flowability of the chicken bouillon raw materials, ensuring the mixer is always in optimal working condition and meeting diverse production needs.

[0021] Both rod 101 and rod 202 have a sliding plate 4 on their inner sides. The surface of the gear 2 is meshed with a rack 3, and two adjacent racks 3 are engaged with the sliding plate 4. The sliding plate 4 and rack 3 located on the inner sides of rod 101 and rod 202 are symmetrically designed. This design allows the two racks 3 to drive the two gears 2 to rotate in opposite directions when moving in the same direction. A slide bar 401 is engaged on the side of the sliding plate 4 away from the rack 3. Both rod 101 and rod 202 have a sliding groove 402 on their inner sides, and the sliding groove 402 is slidably engaged with the slide bar 401. The sliding connection between the sliding groove 402 and the slide bar 401 is used to guide the movement of the sliding plate 4.

[0022] Specifically, a sliding plate 4 is provided on the inner side of rod 101 and rod 202. Two adjacent racks 3 are engaged with the sliding plate 4. The sliding plate 4 and racks 3 located on the inner side of rod 101 and rod 202 are symmetrically designed, so that the two racks 3 can drive the two gears 2 to rotate in opposite directions when moving in the same direction. At the same time, the side of the sliding plate 4 away from the rack 3 is engaged with the slide bar 401. The inner side of the rod has a sliding groove 402 that slides with the slide bar 401 to guide the movement of the sliding plate 4. The above structure enables the moving plate 4 to move synchronously with the racks 3 on both sides, but the symmetrical layout causes the two gears 2 to rotate in opposite directions. The slide bar 401 and the slide groove 402 ensure the smooth movement of the moving plate 4. This achieves reverse drive adjustment of the stirring component 104 under dual-shaft conditions with a single power input. The structure is compact, the guidance is reliable, the number of transmission components is reduced, and the consistency and controllability of the stirring action adjustment requirements are improved.

[0023] One end of the sliding plate 4 is snapped with a sliding rod 5, and two sliding rods 5 extend through the outer sides of rod 101 and rod 2 102 respectively. The sliding rods 5 are coaxially arranged with rod 101 and rod 2 102 respectively. The surface of the sliding rod 5 is snapped with symmetrically arranged snap-fit ​​strips 501. One end of rod 101 and rod 2 102 is provided with a snap-fit ​​groove, and the sliding cooperation between the snap-fit ​​groove and the snap-fit ​​strip 501 will provide a moving guide for the sliding rod 5.

[0024] Specifically, by engaging two moving rods 5 at one end of the moving plate 4, the two moving rods 5 respectively extend through the outer sides of rod 101 and rod 202 and are coaxially arranged with the rods. Symmetrically arranged engaging strips 501 are engaged on the surface of the moving rods 5. Engaging grooves are provided at the ends of rod 101 to slide with the engaging strips 501, providing guidance for the movement of the moving rods 5. The moving rods 5 transmit the movement of the moving plate 4 to the external drive mechanism, and the engaging strips 501 and engaging grooves ensure that the moving rods 5 do not deflect. This allows the internal rack 3 drive interface to be led out to the outside of the rod, facilitating connection to external power while maintaining the axial movement accuracy of the shift rod 5, avoiding poor meshing between the rack 3 and gear 2 due to misalignment, and improving transmission reliability.

[0025] Two moving rods 5 are each fitted with a collar 6 at the end away from rod 101 and rod 202. Support rods 601 are symmetrically arranged and snapped onto the surface of each collar 6. A threaded ring 7 is snapped onto the two support rods 601. A screw rod 701 is coaxially inserted into the inner side of the threaded ring 7 and is threadedly engaged with the threaded ring 7. The rotation of the screw rod 701 will drive the threaded ring 7 to move along its axial direction.

[0026] Specifically, a collar 6 is rotatably fitted onto the ends of two moving rods 5 away from the rod. Symmetrically arranged support rods 601 are engaged on the surface of the collar 6, and a threaded ring 7 is engaged between the two support rods 601. A screw rod 701 is coaxially inserted into the inner side of the threaded ring 7 and threadedly engaged with the screw rod 701. This structure allows the threaded ring 7 to drive the moving rods 5 axially through the support rods 601 and the collar 6 when the screw rod 701 is rotated. The rotatable connection between the collar 6 and the moving rods 5 avoids interference. This converts the rotational motion into the linear motion of the shift rod 5, enabling the adjustment of the direction and angle of the stirring component 104. The threaded drive has good self-locking properties, and the support rod 601 and collar 6 ensure that the shift rods 5 on both sides move synchronously, improving the adjustment accuracy and stability.

[0027] One end of the screw 701 extends through the inner side of the housing 1 and is rotatably connected to the housing 1. The end of the screw 701 located inside the housing 1 is coaxially fixedly sleeved with a worm gear 8. The surface of the worm gear 8 is meshed with a worm 801, and one end of the worm 801 extends through the outer side of the housing 1 and is coaxially fixedly sleeved with a rocker wheel 9.

[0028] Specifically, a screw component 701-101 passes through the outer casing 1 and is rotatably connected. A worm gear 8 is fixedly sleeved on one end of the screw component 701 inside the outer casing 1, and the surface of the worm gear 8 meshes with the worm 801. One end of the worm 801 passes through the outer casing 1 and is fixedly sleeved with a rocker wheel 9. Rotating the rocker wheel 9 drives the worm 801, the worm gear 8, and the screw component 701 to rotate, thus driving the threaded ring 7 to move. This enables precise manual control of the stirring angle. The worm gear 8 and worm 801 transmission have a large reduction ratio and reverse self-locking characteristics to prevent loosening after adjustment. The rocker wheel 9 provides labor-saving operation, facilitates quick on-site adjustment, and improves the ease of operation and safety of the equipment.

[0029] Working principle of the invention: The outer shell 1 of the hybrid structure contains two rods, 101 and 102, arranged in parallel and symmetrical rotation. Both rods have evenly distributed crossbars 103 inserted inside, with the crossbars 103 of rod 101 and 102 arranged in an alternating pattern. A stirring element 104 is symmetrically installed at both ends of each crossbar 103. A gear 2 is coaxially fixed in the middle of each crossbar 103, located inside the rod. A sliding plate 4 is also provided inside the rod, with a rack 3 fixed on it. The gears 2 on adjacent crossbars 103 mesh with the same rack 3. The side of the sliding plate 4 facing away from the rack 3 slides through a sliding strip 401 and a groove 402 on the inner wall of the rod, achieving smooth guidance. One end of the sliding plate 4 is connected to a sliding rod 5, which slides through a locking strip 501 and a locking groove at the end of the rod, extending outwards from the outside of the rod. The ends of the two outer rods 5 are rotatably fitted with collars 6. A threaded ring 7 is connected to the collar 6 via symmetrical support rods 601. A screw rod 701 is coaxially threaded inside the threaded ring 7. A worm gear 8 is fixed to the rear end of the screw rod 701. The worm gear 8 meshes with the worm 801. One end of the worm 801 extends to the outside of the outer casing 1 and is fixed with a rocker wheel 9. Meanwhile, the driving devices for rod one 101 and rod two 102 in this hybrid structure are existing and well-known mature technologies, which will not be described in detail here.

[0030] When the angle of the stirring component 104 needs to be adjusted to accommodate the mixing requirements of different chicken essence ingredients, the operator manually rotates the rocker wheel 9. The rocker wheel 9 drives the worm gear 801 to rotate, which in turn drives the worm wheel 8 and the screw components 701-101 fixed thereto to rotate together. Since the screw component 701 is threadedly engaged with the threaded ring 7, and the threaded ring 7 is connected to the shifting rod 5 through the support rod 601 and the collar 6, the rotation of the screw component 701 is converted into the axial movement of the threaded ring 7, which in turn drives the shifting rod 5 to reciprocate axially through the support rod 601 and the collar 6. The shifting rod 5 pushes the shifting plate 4 and its rack 3 to move inside the rod, and the rack 3 drives the multiple gears 2 meshing with it to rotate simultaneously, thereby causing each crossbar 103 and the stirring component 104 at its end to rotate around its own axis by a certain angle. Because the shifting plate 4 and rack 3 inside rod 101 and rod 202 are symmetrically designed, when the same external force drives the shifting rods 5 on both sides to move in the same direction, the gears 2 inside rod 101 and rod 202 will rotate in opposite directions, ultimately causing the stirring element 104 on rod 101 and the stirring element 104 on rod 202 to form opposite angles. For example, one stirring element 104 tilts forward, while the other tilts backward.

[0031] This design with opposing angles allows the two mixing elements 104 to exert opposing pushing and shearing forces on the material during dual-shaft mixing. The material forms complex convection, vortex, and axial circulation within the casing, effectively avoiding mixing dead zones and significantly improving the dispersion uniformity and mixing efficiency of the components in the chicken bouillon powder (such as salt, sugar, monosodium glutamate, and spices). Simultaneously, due to the large reduction ratio and reverse self-locking characteristics of the worm gear 8 and worm 801 transmission, the angle of the mixing element 104 can be stably maintained after adjustment and will not change due to material resistance. The operator can flexibly adjust the tilt angle of the mixing element 104 according to different chicken bouillon formulas (such as particle size, moisture content, and flowability) using the rocker wheel 9, ensuring the mixer always operates in the optimal material pushing and shearing state, thus meeting diverse production needs. The entire adjustment process requires no machine shutdown or disassembly, is simple to operate, and the angle is continuously adjustable, greatly improving the flexibility of the chicken bouillon production line and product quality.
