Detailed Description

The invention is further described below with reference to the embodiments shown in all the drawings:

example 1:

the fully automatic milk beverage mixing production device described in the embodiment shows an innovative technology and aims to meet the increasing demands of modern markets on diversified milk beverage tastes. The following is a detailed description of this apparatus and further discusses its potential applications and advantages.

First, the carrying part of this apparatus is its supporting frame 1A, which employs a high-strength stainless steel frame, ensuring stability and durability of the apparatus, making it excellent in an industrial production environment.

The core part mounted in the support frame 1A is a chambered mixer 2A which is vertically fixed in the support frame 1A, the mixing tank is made of 30A4 stainless steel, has a structure of an outer shell 21A and an inner core 22A, and has good polishing degree (Ra is less than or equal to 0.4 mu m) so as to ensure food sanitation and quality. The housing is also provided with a 50Amm polyurethane insulation to help maintain the desired temperature conditions. The mixing tank comprises a plurality of functional chambers, each of which can be independently operated, so that milk drinks with various tastes can be processed in the same device. This flexible multi-chamber design is a great innovation in the present apparatus. The bottom of the chambered mixer 2A is provided with a gas delivery system 200.

The core drive system of the apparatus comprises a hollow main drive shaft 3A extending through the mixing tank and a plurality of sub drive shafts 5A. The main drive shaft 3A is provided with a plurality of axially extending holes 31A extending axially at intervals on the side wall, and is connected with the external power unit 4A and driven by chain reduction. The plurality of sub-transmission shafts can be glidingly nested in the main transmission shaft and can be selectively axially locked with the main transmission shaft, so that the stirring system corresponding to the chamber position is driven. The locking of the sub-transmission shafts is controlled by a cylinder-driven actuator 10A. The transmission mode realizes the power distribution and accurate control of different stirring chambers.

Each stirring chamber is internally provided with a stirring impeller 7A, and the blades adopt a modularized design convenient to replace. The driving of the blade is achieved by engagement between the driving coupling 6A and the driven coupling 8A. In this way, even if the impeller needs to be replaced, the continuity of the transmission system is not affected.

Compared with the existing mixing mode of parallel connection of multiple stirring tanks, the coaxial split chamber design of the equipment can effectively reduce the size of the equipment and reduce the cost. Meanwhile, a plurality of stirring systems share main shaft power and a low-temperature environment, so that reasonable utilization of resources is realized. In addition, the working time sequence of each stirring chamber is independently controlled, so that the mixed production of multiple milk drinks can be flexibly organized.

The structural design of the sub-transmission shaft 5A is ingenious, so that the partition driving control of different stirring chambers is realized. Specifically, one end of the sub-transmission shaft 5A corresponds to one of the axially extending holes 31A on the main transmission shaft, and the two shafts are axially locked and matched through a fixed or detachable connecting piece, so that the rotation of the main shaft can be transmitted to the sub-shaft. Meanwhile, the sub transmission shaft and the main transmission shaft 3A can slide in the axial direction, and the sliding range is limited by the size of the axial extension hole, so that the transmission is realized, and the relative independence of the sub transmission shaft is ensured. The other end of each sub-transmission shaft 5A is exposed outside the main shaft respectively, and a gap is left between the sub-transmission shafts, so that a connecting device is arranged at the outer end of each sub-transmission shaft 5A, and the sub-transmission shafts 5A are driven to move through external power.

In this embodiment, 3 sub-transmission shafts with different lengths, namely, a first sub-transmission shaft, a second sub-transmission shaft and a third sub-transmission shaft, are nested in a coaxial sleeve manner. The first sub-transmission shaft 5A1 has 3 sections of different diameters, the second sub-transmission shaft 5A2 has two sections of different diameters, the middle section of the first sub-transmission shaft 5A1 is sleeved with the lower section of the second sub-transmission shaft 5A2, the upper section of the first sub-transmission shaft 5A1 is sleeved with the upper section of the second sub-transmission shaft 5A2, and the second sub-transmission shaft 5A2 is sleeved with the third sub-transmission shaft 5A3. The design mode of the series nesting ensures that different sub-transmission shafts can rotate relatively independently, and can reasonably utilize limited axial space, thereby showing the compactness and the flexibility of the transmission system.

The drive couplings 6A provided for each sub-transmission shaft 5A are key components for realizing transmission. The driving connecting piece is sleeved on the periphery of the main transmission shaft 3A in a sliding sleeve mode, is made of stainless steel, and has high axial load capacity.

Each driving coupling member 6A is fixedly connected with the corresponding sub-transmission shaft 5A, so that the driving coupling members 6A can slide up and down along with the sub-shafts, and the rotation of the sub-transmission shafts 5A is transmitted to the driving coupling members. The lower end of the driving coupling member 6A is provided with toothed engaging portions 6A2 which engage with mating teeth of the driven coupling member 8A on the impeller 7A to form a mechanical locking transmission to drive rotation of the impeller.

By this connection, the drive coupling 6A achieves both transmission of rotation of the sub-shaft and selective engagement with the driven coupling 8A to control the stirring action of the corresponding stirring chamber. This flexible and controllable driving mode is an important component of the innovation point of the device.

A stirring impeller 7A corresponding to the stirring chamber is arranged below each driving connecting piece 6A, is fixed on the periphery of the main transmission shaft 3A in a sleeved mode, is tightly matched with the main transmission shaft, and can realize relative rotation.

The stirring impeller 7A is composed of a frame 7A1 made of stainless steel and a plurality of blades 7A2 with detachable middle. The blade is detachably mounted on the frame through bolts and the like, so that the blade is convenient and quick to realize even if the blade needs to be replaced.

Through the engagement of the driving coupling member 6A and the driven coupling member 8A, the rotation of the main transmission shaft can be precisely transmitted to the stirring impeller to drive the blades to rotate so as to stir the liquid in the container. The modularized design not only improves the universality of the stirring system, but also is convenient for maintenance.

Fixed to the upper end face of the center shaft of each stirring impeller 7A, also fitted around the outer periphery of the main drive shaft 3A, is a driven coupling 8A. The driven coupling 8A is in a tight rotatable fit with the spindle.

The upward facing surface of the top end of the driven coupling member 8A is provided with a tooth-shaped structure which matches the locking teeth 6A2 on the driving coupling member 6A. When the driving connecting piece 6A moves downwards, the driving connecting piece 6A and the driven connecting piece are meshed in a tooth shape, so that the rotation of the driving connecting piece 6A can be accurately transmitted to the driven connecting piece 8A and the stirring impeller 7A, and the driven connecting piece 8A and the stirring impeller 7A are driven to rotate to perform stirring operation.

The mating engagement of driven coupling 8A with drive coupling 6A is critical to achieving zoned drive control of each individual mixing system. When the sub-transmission shaft 5A moves up, the two connectors are disconnected, and the corresponding stirring system stops working. This flexible manner of engagement is an important component of the innovation of the present apparatus.

To achieve a zoned mixing of milk drinks of different tastes, a separate stirring chamber 9A is provided at the periphery of each stirring impeller 7A. The stirring chamber 9A is fixed to the inner wall of the inner core 22A by a connecting piece 9A 1.

At least one end of the stirring chamber 9A is of a detachable structure, so that the stirring impeller 7A inside can be conveniently detached for maintenance or replacement. The stirring chamber 9A is provided with a corresponding feed inlet and a corresponding discharge outlet, and can be connected with an external pipeline system to realize the introduction of raw materials and the discharge of products.

The design of the independent chamber structure realizes the isolation and mixing of different taste products, prevents cross contamination and greatly improves the quality stability of the products. Meanwhile, each chamber can be independently cleaned and disinfected, so that the disassembly workload of equipment is reduced.

The apparatus is provided with an actuator 10A which is movable by being forced solely in the axial direction of the sub-transmission shaft 5A. The actuator 10A includes:

(1) Ball pin rotating parts 11 respectively fixed at the exposed ends of each sub transmission shaft 5A;

(2) A lift lever 12 pivotally connected to each of the rotary members 11;

(3) A support base 13 for independently hinging one end of each lifting rod 12;

(4) A propulsion cylinder 14 powering each lift rod 12.

When the pushing cylinder 14 applies force, the lifting rod 12 drives the rotating part 11 and the sub-transmission shaft 5A to move upwards or downwards so as to separate or engage the driving and driven connecting pieces, thereby controlling the start and stop of the corresponding stirring system.

The actuator 10A may also be in other prior art forms, such as a motor drive, to achieve precise control of the movement of the sub-shaft. This flexible manner of operation is an important means of achieving zone control of each individual stirring system.

After all the equipment parts are assembled, the power device 4A is started to drive the main transmission shaft 3A in a rotating mode. At the same time, the control of the internal temperature of the split-chamber mixer 2A is achieved by means of a delivery duct for cold or hot air.

Different kinds of materials to be stirred are respectively injected into each independent stirring chamber 9A. Then, for each stirring chamber, the thrust action of the corresponding air cylinder 14 is controlled to drive the lifting rod 12 to rotate so as to push the corresponding sub-transmission shaft 5A to move downwards. In this way, the engagement teeth 6A2 of the driving coupling 6A are brought into engagement locking with the driven coupling 8A. At this time, the sub-transmission shaft 5A drives the stirring impeller 7A to rotate through the main transmission shaft 3A, and the materials in the room are stirred and mixed.

If stirring is stopped, the air cylinder 14 is released, the lifting rod 12 returns, the sub-transmission shaft 5A moves upwards, the meshing teeth of the two connecting pieces are separated, and the stirring system stops working.

Through the structural design and the accurate control, the selective stirring operation of the materials in each independent stirring chamber can be realized, and meanwhile, different stirring chambers can share the resources of the power device 4A, the low-temperature environment and the like, so that various economic and efficient mixing operations are realized. In addition, if the materials in different chambers are required to be remixed, the nearby positions between the upper chamber and the lower chamber can be directly utilized for fluid transportation, so that the operation is simplified, and the quality loss risk is reduced.

To improve the reliability of engagement between the engagement teeth 6A2 of the driving link 6A and the driven link 8A, an engagement lifting mechanism 100 is designed, which includes:

1. the driven connecting piece 8A and the locking teeth 6A2 are of rectangular tooth-shaped design and have a certain axial height extension;

2. the outer ring teeth of the driven connecting piece 8A are sleeved with a meshing enhancement assembly 20A which can slide up and down but does not rotate;

3. a convex arc section 30A is additionally arranged at the center of the upper end of the independent stirring chamber 9A, and the height transition of the section is gentle;

4. the lower end of the meshing enhancement assembly 20A is provided with an annular groove 40A which can be matched with the convex arc section 30A, and a roller 50A is radially arranged in the annular groove;

5. when engagement reinforcement assembly 20A is not rotating, the dead weight causes annular groove 40A to intersect with raised section 30A, with roller 50A at the lowest point;

6. when the engagement enhancing assembly 20A rotates, the roller 50A rolls on the convex section 30A to drive the engagement enhancing assembly 20A to move upwards as a whole;

7. at this point, engagement reinforcement members 20A enter locking teeth 6A2 and co-engage with the outer ring teeth of driven coupler 8A.

Through the structural design, the engagement part forms common transmission of three parts, so that the engagement strength and stability are greatly improved, and the device is an innovation point.

To enable engagement enhancing assembly 20A to remain stably in the operative position, the following additional structural design is implemented:

1. an annular flanging 21 is arranged on the outer ring of the upper end of the meshing enhancement assembly 20A;

2. a limiting shell 60A is added at the center of the upper end of the independent stirring chamber 9A, the upper part of the housing is opened, and the lower part of the housing is provided with a concave positioning ring 61;

3. a plurality of elastic pins 70A are arranged on the peripheral surface of the driving connecting piece 6A at intervals, the outer ends of the pin bodies are round heads, and the pin bodies can fall into the positioning rings 61;

4. the inner end of the elastic pin 70A is provided with a double inclined surface 71, and the upper inclined surface can be abutted against the lower edge of the flanging 21;

5. when the driving connecting piece 6A moves downwards, the round head enters the positioning ring 61, the elastic pin 70A stretches in, and the upper inclined surface abuts against the flanging 21;

6. at this time, engagement enhancing assembly 20A is supported by double inclined surface 71 and does not fall even if the thrust of cylinder 14 fails.

By this design, the engagement enhancing member 20A can be stably held at the operating position, and the engagement failure when the cylinder thrust is insufficient is avoided, while the noise influence when operating is reduced.
