[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1

[0033] See Figures 1 to 7 As shown, a tea beverage processing and mixing device includes a support assembly and a mixing assembly. The support assembly includes a placement frame 1, several support legs 2 installed at the lower end of the placement frame 1, and a controller 3 located at the side end of the placement frame 1. The mixing assembly includes a mixing tank 4 installed inside the placement frame 1, a power motor 5 located at the middle of the upper end of the placement frame 1, a first control line installed at the side end of the power motor 5, a stirring rod 6 rotatably installed inside the mixing tank 4, an external discharge pipe 41 located at the bottom end of the mixing tank 4, several hanging sleeves 7 equidistantly circumferentially installed at the side end of the placement frame 1, a dispensing mechanism 8 sleeved on the hanging sleeves 7, a first liquid level sensor 42 located inside the mixing tank 4, a feed pipe 43 equidistantly circumferentially installed at the top end of the mixing tank 4, a serial number plate 44 located on the mixing tank wall at the side end of the feed pipe 43, and a feeding pipe 9 connecting the dispensing mechanism 8 and the feed pipe 43.

[0034] The feed pipe 43 has an external thread at its upper end, which is threaded to a sealing cap at the top of the feed pipe 43. The sealing cap has an internal thread that matches the external thread. This allows the feed pipe 43 to be sealed when not in use to prevent foreign matter from entering.

[0035] The feeding pipe 9 is equipped with connectors at both ends that are compatible with the output port of the conveying pump and the feed pipe.

[0036] An on / off valve is provided in the middle of the external drain pipe 41. The on / off valve is a conventional pipe knob valve, such as a faucet valve.

[0037] The batching mechanism 8 includes a housing 81, a snap-fit ​​block 82 installed on the side of the housing 81, a replenishment pipe located at the top of the housing 81, a sealing cap installed on the replenishment pipe, a delivery pump located at the bottom of the housing, a second liquid level sensor 83 installed inside the housing, a second control line located at the top of the housing, a handle 84 rotated at the top of the housing 81, connecting the liquid inlet of the delivery pump to the liquid inlet pipe inside the housing 81, and one end of the feeding pipe 9 connected to the output port of the delivery pump; the snap-fit ​​block 82 snaps into the inside of the hanging sleeve 7; the second liquid level sensor 83 and the delivery pump are both electrically connected to the external control line. Through the cooperation of the snap-fit ​​block 82 and the hanging sleeve 7, modular installation and disassembly of the batching boxes are achieved, thus enabling flexible addition or removal of batching boxes as needed; through the configuration of the delivery pump and the second liquid level sensor 83, an intelligent delivery and monitoring foundation for a single batching unit is constructed, providing core execution and feedback components for active and precise control of the output of each batching box, thereby creating conditions for proportional feeding.

[0038] The first liquid level sensor 42 and the second liquid level sensor 83 are both non-contact liquid level sensors, such as ultrasonic liquid level sensors; the delivery pump is a conventional pumping pump.

[0039] The placement frame 1 includes a base frame 11, stabilizing rods 12 equidistantly arranged on the upper end of the base frame 11, a stabilizing ring 13 mounted on the upper end of the stabilizing rods 12, and a motor frame 14 mounted on the upper end of the stabilizing ring 13. The placement frame 1 covers the outside of the mixing tank 4. The inner wall of the placement frame 1 is tightly fitted to the outer wall of the mixing tank 4. Support legs 2 are equidistantly distributed on the lower end of the base frame 11, and at least three support legs 2 are provided. Hanging sleeves 7 are equidistantly distributed on the side wall of the stabilizing ring 13. The power motor 5 is mounted in the middle of the motor frame 14, and the output end of the power motor 5 is connected to one end of the stirring rod 6. The overall mechanical stability and spatial layout of the device are optimized. The design of the stabilizing rods 12 and the stabilizing ring 13 ensures that the mixing tank 4 remains stable during operation. The setting of the motor frame 14 provides a dedicated and reliable installation position for the power motor 5. The entire structural design ensures that the automated stirring process can be carried out smoothly and efficiently.

[0040] The motor frame 14 is provided with a first electrical connection hole, and the stabilizing ring 13 is provided with a plurality of second electrical connection holes 131 at equal intervals. The second electrical connection holes 131 are located at the side end of the hanging sleeve 7 and electrically connect the first electrical connection hole and the transmission wire of the controller 3, and electrically connect the second electrical connection holes 131 and the transmission wire of the controller 3. The motor frame 14, the stabilizing ring 13, the stabilizing rod 12 and the base frame 11 are all provided with guide grooves adapted to the transmission wires. Through the preset electrical connection holes and internal guide grooves, a standard and safe channel is provided for power transmission and signal communication between the controller 3, the power motor 5 and the various modular batching mechanisms 8. This solves the problem of messy wiring and inconvenient connection caused by the addition or removal of batching boxes, improves the electrical safety, aesthetics and convenience of modular connection of the equipment, and is an important auxiliary design to support the realization of modular functions.

[0041] The dimensions of the snap-fit ​​block 82 are adapted to the internal dimensions of the hook sleeve 7, ensuring the mechanical reliability and interchangeability of the modular connection and guaranteeing that each dispensing mechanism 8 can be accurately and firmly installed in place.

[0042] A pressure-sensitive sensor 71 is installed at the upper end of the mounting sleeve 7. This is key to achieving intelligent management; its purpose is to automatically detect whether a batching mechanism is attached and to feed this status signal back to the controller. This makes it possible for the system to automatically identify online batching units and activate or disable the corresponding control unit (sub-control board 32), which is the basis for realizing "plug and play" and status indication functions.

[0043] The transmitting wire is equipped with a connector plug at its end that is compatible with the first electrical connection hole and the second electrical connection hole 131. This further simplifies electrical connection operations and improves the convenience of modular assembly. The plug connection method makes the circuit connection of the dispensing mechanism 8 as simple as plugging and unplugging a household appliance, and is completed simultaneously with the mechanical snap-fit ​​action, which greatly reduces the difficulty and time of operation, and truly realizes the modular design concept.

[0044] The controller 3 includes a main control board 31 and several sub-control boards 32. The main control board 31 controls the power motor 5 and the first liquid level sensor 42. Each sub-control board 32 controls a single dispensing mechanism 8. Status lights 33 are installed on the side of the sub-control boards 32, and serial number stickers 34 are installed on the side of the status lights 33. The serial number stickers 34 indicate the serial number of the sub-control board 32, and each serial number sticker 34 corresponds one-to-one with a serial number plate 44. A distributed, intelligent control system is constructed; its core purpose is as follows:

[0045] The main control board 31 controls the mixing core (sub-control board 32, power motor 5, and first liquid level sensor 42) to achieve automation of the mixing process.

[0046] The sub-control board 32 precisely controls each batching mechanism 8 one-to-one, solving the problem of independent and proportional quantitative control of multiple batching components; each sub-control board 32 independently controls the start, stop and duration of the corresponding conveying pump according to the instructions of the main control board 31 and sensor feedback, thereby achieving precise feeding.

[0047] The corresponding design of status lights 33, serial number stickers 3, and serial number plates 44 provides an intuitive human-machine interface, enabling operators to clearly understand the material feeding status of each workstation (such as whether it is installed or whether it is feeding), which facilitates monitoring and troubleshooting.

[0048] The controller 3 is equipped with an external power supply cable on its side, which can be connected to an external power source to supply power to the device.

[0049] Both the main control board 31 and the secondary control board 32 adopt PLC control boards; the selection of the control core is clarified, the purpose of which is to ensure the reliability, stability and powerful logic function of the control system, and to facilitate the implementation of complex control processes.

[0050] Each sub-control board 32 is electrically connected to the pressure-sensitive sensor 71 of its corresponding mounting sleeve 7 via a transmission wire; the pressure-sensitive sensor 71 provides feedback to control the status light 33 to turn on and off. This completes the closed-loop control from status detection (pressure-sensitive sensor 71) to logic processing (sub-control board 32) and then to result output (status light 33). This makes the "module detection" function no longer isolated, but deeply integrated with the user interface, ultimately enabling the equipment to proactively "inform" the user of the real-time status of each batching station, greatly improving the intelligence of the equipment and the user experience.

[0051] Example 2

[0052] A method of using a tea beverage processing and mixing apparatus includes the following steps:

[0053] Step 1: Equipment preparation and connection with the batching mechanism

[0054] 1. Inspection and positioning: Ensure the device is placed stably, controller 3 is powered on (connect the external power cord to the external power source), and all components are normal;

[0055] 2. Formula planning: Based on the formula of the target tea beverage, determine the types and quantities of ingredients required;

[0056] 3. Additive loading mechanism 8: The additive loading mechanism 8, which contains different liquid ingredients (such as tea extract, sugar solution, fruit juice concentrate, etc.), is attached to the mounting sleeve 7 on the side of the stabilizing ring 13 of the placement frame 1 through the snap-fit ​​block 82 on its side end; a "click" sound indicates that the mechanical connection is in place.

[0057] 4. Electrical Connection: Insert the connector of the transmission wire on the side of the batching mechanism housing 81 into the second electrical connection hole 131 next to the mounting sleeve 7. At this time, the status light 33 of the corresponding sub-control board 32 on the controller 3 should light up, indicating that the system module has been recognized and activated.

[0058] Step 2: Parameter Setting and Association Confirmation

[0059] 1. Pipeline connection: Connect one end of the feeding pipe 9 to the outlet of the conveying pump that has been attached to the batching mechanism 8, and connect the other end to the corresponding feed pipe 43 at the top of the mixing tank 4; make sure that the serial number plate 44 corresponds one-to-one with the serial number sticker 34 on the sub-control board 32 on the controller 3. For example, the batching mechanism 8 connected to the feed pipe 43 with serial number "A001" should be controlled by the sub-control board 32 with serial number sticker "A001".

[0060] 2. Setting the proportion: On the controller 3, set the corresponding material delivery parameters (such as delivery time or delivery amount based on feedback from the second liquid level sensor) for each activated sub-control board 32; these parameters together constitute the formula proportion for this mixing.

[0061] Step 3: Perform mixed processing

[0062] 1. Start mixing: Start the power motor 5 via the main control board 31 on the controller 3, and the stirring rod 6 will start to rotate in the mixing tank 4 to perform pre-stirring or prepare for mixing;

[0063] 2. Automatic sequential feeding: Start the automatic feeding program; the main control board 31 of the controller 3 will, according to the preset formula, instruct each sub-control board 32 to control its corresponding conveying pump to pump each ingredient into the mixing tank 4 in a precise proportion.

[0064] • Operators can monitor the feeding process by observing status light 33 (such as flashing to indicate feeding, solid light to indicate standby, and off to indicate no connection);

[0065] • The second liquid level sensor 83 monitors the material level inside the tank 81 in real time. When the material level is too low, it can send a signal to the controller 3 to trigger an alarm or stop the pump from working.

[0066] 3. Liquid level monitoring and process completion: The first liquid level sensor 42 monitors the total liquid level in the mixing tank 4 in real time; when the liquid level reaches the preset height, or when all the batching mechanisms 8 have completed the conveying according to the formula, the controller 3 will automatically stop all conveying pumps to complete the feeding process; the power motor 5 continues to work to fully and evenly stir the mixture.

[0067] Step 4: Material Discharge and Subsequent Operations

[0068] 1. Mixing complete: After the set mixing time is reached (the controller 3 has a built-in timer), the controller 3 will automatically stop the power motor 5;

[0069] 2. Discharge the finished product: Open the valve in the middle of the drain pipe 41 at the bottom of the mixing tank 4 to open the drain pipe 41 and discharge the well-mixed tea beverage for subsequent filling.

[0070] 3. Modular disassembly and cleaning: After production is completed, the transmission wires can be easily disconnected, and each batching mechanism 8 can be removed from the mounting sleeve 7 for individual cleaning and material replenishment, in preparation for the next production; the batching mechanism 8 can be flexibly replaced or added or removed according to the formula of different products.
