Description

Technical Field

[0001] This invention relates to a fully automatic batching machine, and more particularly to a dual-mode batching machine for automated flavor formulation equipment. The invention also provides a batching method for the dual-mode batching machine. Background Technology

[0002] Flavors and fragrances, as volatile organic compounds that can be perceived by smell or taste, are widely used in food, daily chemicals, tobacco, pharmaceuticals, and novel heated non-combustible products. Their formulations typically exhibit the significant characteristics of being "multi-component, high-value in trace amounts, and highly precise with strong consistency." Especially in the field of tobacco flavorings and functional flavor raw materials, a single formulation often contains both milligram-level trace active ingredients and kilogram-level matrix solvents, placing extremely high demands on batching equipment in terms of metering accuracy, system stability, prevention of cross-contamination, automation level, and adaptability to a wide range of formulations. However, existing automated flavoring batching systems generally struggle to simultaneously meet the industrial demands for high-precision continuous batching across orders of magnitude—from trace to medium to large quantities—on a single equipment platform.

[0003] The invention patent document CN113289543A, entitled "Automatic Batching System and Tobacco Flavoring Batching Machine," describes an automatic batching system and a tobacco flavoring batching machine. The technical solution involves setting up a batching guide rail, with the batching container and weighing device integrally mounted on a movable base. A drive device moves the batching container sequentially to below each fixed discharge nozzle, and the raw materials are sequentially added to the same container via valves or flow meters to complete the batching process. This technical solution suffers from the following insurmountable technical defects: (1) Dynamic weighing error cannot be eliminated: The weighing device moves with the base as a whole and is continuously affected by inertial force and structural vibration during start-up, shutdown and positioning. It must be frequently zeroed and compensated, making it difficult to achieve stable mg-level micro-weighing in the long term; (2) Multiple raw materials share the same outlet and pipeline: Different flavorings need to be transported through the same pipeline and nozzle, and residual liquid is unavoidable, which is very easy to generate cross-contamination and cross-flavoring; (3) It is impossible to build a fully enclosed negative pressure weighing environment: The mixing port must be open to the outside, which is not conducive to forming a stable micro-negative pressure anti-escape environment; (4) Micro- and large-volume metering logic is separated: Micro-volume relies on flow rate calculation, while large-volume relies on dynamic weight accumulation, lacking a unified static weight closed-loop control system.

[0004] A utility model patent document with authorization announcement number CN217939993U and titled "Fully Automatic Flavor Mixing Machine" describes a fully automatic flavor mixing machine. The design employs a fixed number of flavor cylinders on a fixed plate for the mixing cylinders, and a corresponding number of mixing valves on a fixed plate for the mixing valves. An electronic scale is independently fixed at a predetermined position along the circular motion trajectory of the mixing valves. Each flavor cylinder is connected to its corresponding mixing valve via an independent mixing delivery pipe. This design integrates multiple sets of raw material tanks, valve groups, and weighing devices onto a single frame for automatic flavor mixing. Raw materials are sequentially added from fixed tanks to the same mixing container to achieve automatic flavor mixing.

[0005] This technical solution still belongs to a single-machine centralized batching structure. Its raw material tank is fixedly installed on the equipment body, and the batching path still relies on fixed pipeline connections. It does not have the ability to palletize raw material units, transport pallets back to the warehouse, and independently clean and reuse pallets. At the same time, its metering mode is mainly based on a single weighing unit, which is suitable for the automated preparation of precise small samples in the laboratory. It is difficult to take into account the dual-mode high-precision dynamic weight gain metering of trace components and bulk components on the same equipment, and it cannot realize multi-station parallel operation and pallet-level full life cycle management.

[0006] A utility model patent document with authorization announcement number CN222401297U, entitled "An Automatic Flavoring Dispensing Device," discloses an automatic flavoring dispensing device. The device includes a feeding mechanism, a barcode scanning mechanism, raw material components, and a weighing mechanism arranged around the rotating periphery of the feeding mechanism. It automatically grasps and weighs flavoring raw materials using a four-axis handling robot, electric cylinder grippers, a barcode scanning mechanism, and a precision electronic balance, achieving automatic flavoring dispensing in a laboratory setting. However, this solution still belongs to a single-machine centralized dispensing device. (1) The raw material components and weighing mechanism are fixed on the equipment base and do not have the ability to coordinate pallet return and three-dimensional warehousing. (2) The raw material storage unit and the metering execution unit were not constructed into an "integrated storage and distribution pallet", nor was a non-contact alignment injection structure formed between the pallets; (3) It does not involve multi-pallet weight-adding batching under static batching scales, nor does it solve the systemic problem of "all components reaching a precision of one part per thousand" in 1000 kg batching in the cigarette industry. The common technical bottlenecks of the above-mentioned existing technologies.

[0007] A comprehensive analysis of the mainstream ingredient mixing technologies disclosed in the aforementioned comparative documents reveals the following common technical bottlenecks in existing automatic flavor mixing systems: (1) The cross-contamination problem caused by the public pipeline structure cannot be fundamentally eliminated; (2) Micro-batch preparation generally relies on flow rate or time conversion, lacking a true static weight closed loop; (3) Micro, medium and large quantities are often measured by different devices, resulting in serious system redundancy; (4) It is difficult to achieve uniform high-precision batching across orders of magnitude from mg to kg in a single device; (5) It is difficult to simultaneously meet the comprehensive process requirements of tobacco flavoring for "high cleanliness, full enclosure, anti-escape and high repeatability".

[0008] In view of the fundamental defects of the existing technology in terms of structural principle, metering method, pollution prevention capability and process adaptability, the core technical problem to be solved by the present invention is: How can a dual-mode high-precision batching system be developed within the same equipment set, simultaneously covering both mg-level micro-batch and g-kg-level medium-to-large-range batching, while ensuring cross-contamination prevention, a fully enclosed micro-negative pressure environment, and highly automated operation, through static weight closed-loop control, under the premise of completely eliminating public delivery pipelines?

[0009] Based on the problems of existing batching machine applications, this invention proposes an innovative batching machine design structure and batching method, which can achieve a high-precision, high-efficiency, and high-stability automated working process, while also achieving a wide range of formulation effects.

The integrated storage and distribution raw material tank tray has multiple tanks of different volumes. Each tank is equipped with a syringe or a high-precision dispensing valve, or a syringe and a high-precision dispensing valve. By combining the two dispensing modes, it can meet the dispensing operation requirements of high precision, high efficiency and wide formula dispensing range. The integrated storage and distribution batching tank tray is equipped with a single tank of suitable volume, and the tank is equipped with a high-precision batching valve and a stirrer. When heating the batching tank, a heating jacket can be added. The prepared raw materials can be automatically stirred at room temperature or heated and cooled. This batching tank tray can be used as a raw material tank tray for batching, or it can be directly filled and discharged. The batching machine proposed in this invention includes two batching modes: Mode 1: Syringe-type dispensing machine, which dispenses ingredients using a syringe attached to the raw material tank and a small-range dispensing scale on the weighing mechanism of the dispensing cup; Mode 2: The batching machine with dual precision batching valve mode performs dual precision batching through a high-precision batching valve on the raw material tank, a small-range batching scale on the batching cup weighing mechanism, and a large-range batching scale on the batching tank weighing mechanism.

[0011] This invention also provides two different batching methods for the batching machine, including: Method 1: Syringe-based dispensing method. This method uses a syringe attached to the raw material container and a small-range dispensing scale on the weighing mechanism of the dispensing cup for high-precision, small-range dispensing. It includes the following steps: When the amount of a single component of raw material is small, the pallet of the integrated storage and distribution batching tank is transported back and forth by the batching tank conveying mechanism and positioned on the large-range batching scale of the batching tank weighing mechanism to carry out the weighing and tare operation of the batching tank before batching. The integrated storage and distribution raw material tank pallet is transported left and right by the raw material tank conveying mechanism to the batching position. The Y-axis linear module and X-axis linear module of the batching robot mechanism work together with the batching cup pouring mechanism to take out the batching cup from the storage mechanism and transport it to the small-range batching scale of the batching cup weighing mechanism for weighing and tareing the batching cup before batching. The syringe dispensing mechanism grabs the syringe and draws raw material from the raw material tank, moves it above the dispensing cup to dispense a small amount of raw material, and stops dispensing when the amount of raw material reaches the weight set and controlled by the weighing mechanism of the dispensing cup, and then dispenses the next batch of raw material. If the maximum capacity of the mixing cup is reached during the filling process, the mixing cup pouring mechanism will automatically grab the mixing cup and pour the raw materials into the mixing tank. Then, the mixing cup will be placed back on the small-range mixing scale for filling again until all raw materials have been filled. The solvent adding mechanism automatically adds solvent to the dispensing cup and cleans the dispensing cup with the solvent. After cleaning, the dispensing cup pouring mechanism adds the tail material to the dispensing tank, completing the high-precision small-volume dispensing in syringe mode.

[0012] Method 2: Dual-precision dispensing valve mode dispensing method. This method uses a high-precision dispensing valve on the raw material tank and a small-range dispensing scale on the dispensing cup weighing mechanism and a large-range dispensing scale on the dispensing tank weighing mechanism to perform high-precision medium-range dispensing and high-precision large-range dispensing, including the following steps: (1) When the amount of raw material in a single component is medium: The integrated storage and distribution batching tank pallet is transported back and forth by the batching tank conveying mechanism and positioned onto the large-range batching scale of the batching tank weighing mechanism for weighing and tareing the batching tank before batching. The integrated storage and distribution raw material tank pallet is transported left and right by the raw material tank conveying mechanism and positioned at the dispensing position of the dispensing cup weighing mechanism, located directly above the dispensing cup filling port; The Y-axis linear module and X-axis linear module of the batching robot mechanism work together with the batching cup pouring mechanism to take out the batching cup from the storage mechanism and transport it to the small-range batching scale of the batching cup weighing mechanism for weighing and tareing the batching cup before batching. The nitrogen filling mechanism automatically connects to the nitrogen filling check valve of the integrated storage and distribution raw material, and adds constant pressure nitrogen into the raw material tank. The batching valve opening mechanism automatically connects to the high-precision batching valve on the raw material tank. After the valve is opened, the raw materials in the raw material tank are added to the feeding cup through the feeding valve under nitrogen pressure. The feeding stops when the amount of raw materials reaches the weight set and controlled by the weighing mechanism of the feeding cup, and then the next batch of raw materials is added. If the maximum capacity of the mixing cup is reached during the filling process, the mixing cup pouring mechanism will automatically grab the mixing cup and pour the raw materials into the mixing tank. Then, the mixing cup will be placed back on the small-range mixing scale for filling again until all raw materials have been filled. The solvent adding mechanism automatically adds solvent to the dispensing cup and cleans the dispensing cup with the solvent. After cleaning, the dispensing cup pouring mechanism adds the tail material to the dispensing tank, completing the high-precision medium-range dispensing in the dual-precision dispensing valve mode. (2) When the amount of raw material in a single component is large: The integrated storage and distribution batching tank pallet is transported back and forth by the batching tank conveying mechanism and positioned onto the large-range batching scale of the batching tank weighing mechanism for weighing and tareing the batching tank before batching. The integrated storage and distribution raw material tank pallet is transported left and right by the raw material tank conveying mechanism and positioned at the dispensing position of the weighing mechanism of the batching tank, located directly above the filling port of the batching tank; The nitrogen filling mechanism automatically connects to the nitrogen filling check valve of the integrated storage and distribution raw material, and adds constant pressure nitrogen into the raw material tank. The batching valve opening mechanism automatically connects to the high-precision batching valve on the raw material tank. After the valve is opened, the raw materials in the raw material tank are directly added to the batching tank under nitrogen pressure through the batching valve. The addition stops when the batching amount reaches the weight set and controlled by the weighing mechanism of the batching tank, and then the next batch of raw materials is added until all raw materials are added. The solvent adding mechanism automatically adds solvent to the mixing tank, completing high-precision, large-range mixing in the dual-precision mixing valve mode; Furthermore, the integrated storage and distribution raw material tank tray is equipped with multiple tanks of different volumes. Each tank is equipped with a syringe, or a high-precision dispensing valve, or a syringe and a high-precision dispensing valve. By combining different dispensing modes, it can meet the dispensing operation requirements of high precision, high efficiency and wide formula dispensing range. Furthermore, the integrated storage and distribution tank tray is equipped with a single tank of suitable volume, and different volumes of tanks can be matched according to specific applications. The tank is equipped with a high-precision dispensing valve and a stirrer. A heating jacket can be added when heating the dispensing tank. The prepared raw materials can be automatically stirred at room temperature or heated and cooled. This dispensing tank tray can be used as a raw material tank tray for dispensing, or it can be directly filled and discharged.

[0013] This invention proposes a dual-mode batching machine and two different batching methods, employing an integrated storage and batching system structure. This integrates raw material storage and batching, offering greater system flexibility compared to existing technologies. It eliminates raw material transport pipelines, significantly reducing system complexity, raw material pipeline losses, and pipeline cleaning issues. Material replacement is convenient, saving investment and operating costs. It boasts superior batching accuracy and a wider accuracy range. Using the dual-mode batching method, the total batching volume (grams-tons) achieves a batching accuracy of 0.1% and a repeatability of 0.3%. The minimum batching amount for a single component is 2g, reducing fragrance pretreatment (dilution) steps and allowing direct batching to large batching tanks. For high-valent active components at the mg level in the formulation, this component can be pre-prepared into a high-concentration mother liquor, then batched at a mass accuracy of 2g or higher. This achieves indirect and precise control of mg-level effective components under static weight closed-loop conditions, eliminating the need for graded fragrance blending and realizing efficient and high-precision digital fragrance blending. The dual-mode batching machine of this invention moves the raw material tanks, which are automatically called from the high-bay warehouse to the batching machine for batching. All the high-precision scales on the batching machine are fixedly installed and operate in a static weighing mode. The high-precision scales are calibrated in place to avoid horizontal offset errors caused by moving scales. They are highly accurate, have a stabilization time of less than 2 seconds, and have a fast batching speed and high working efficiency, enabling higher output. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Those skilled in the art will understand that the embodiments described herein are only a part of the embodiments that can be implemented by the present invention, and not exhaustive of all embodiments. Other application embodiments that can implement the technical solutions of the present invention also fall within the scope of protection of the present invention. In this patent specification, "an example," "an embodiment," or "an application example" refers to a specific feature, structure, or characteristic described in the example being included in at least one example of the present invention. Therefore, the phrases "in an example," "in an embodiment," or "in an application example" appearing in different places throughout this specification do not necessarily refer to the same example. Furthermore, in one or more examples, specific features, structures, or characteristics can be combined in any suitable manner.

[0017] The following detailed description of the present invention is provided in conjunction with the accompanying drawings and embodiments provided in the present invention patent application.

[0018] Figure 1A and 1B The figure shows a cross-sectional view of the internal mechanisms of the dual-mode batching machine. As shown, the dual-mode batching machine of this invention mainly includes a batching robot unit 1, a batching valve cleaning mechanism 2, a batching cup weighing mechanism 3, a batching cup storage mechanism 4, a batching tank conveying mechanism 5, a raw material tank conveying mechanism 6, a batching tank stirring mechanism 7, an integrated storage and batching raw material tank 8, a batching tank weighing mechanism 9, an integrated storage and batching batching tank 10, and a micro-negative pressure exhaust frame 11. Detailed implementation schemes of each functional mechanism of the dual-mode batching machine proposed in this invention are described in conjunction with other accompanying drawings. (Attached) Figure 2This is a schematic diagram of the micro-negative pressure exhaust frame. As shown in the figure, the sheet metal cover 209 is installed on the outer sides of the sheet metal frame 202, forming the main structure of the micro-negative pressure exhaust frame 11 of the batching machine. The table panel 201 is installed inside the cover. Glass doors 211, with hinges 210, are installed on both sides of the front of the micro-negative pressure exhaust frame 11. When closed, door proximity switches 203 fixed to the upper and lower ends of the sheet metal frame 202 detect this and ensure the glass door 211 is closed. Simultaneously, a sealing strip 207 is installed on the front of the sheet metal frame 202 to ensure the glass door 211 is sealed and prevent air leakage. The sheet metal cover 209, installed on the top of the sheet metal frame 202, is equipped with a negative pressure exhaust port 208 to provide negative pressure adsorption and exhaust the waste gas generated during batching inside the frame. A sliding door 205 is installed on the back of the sheet metal frame 202, which, together with the sliding cylinder 206 at the top and the sliding door guide rail 204 at the bottom, controls the loading and unloading of the batching machine.

[0019] On the left side of the worktable 201, there is a fixed ingredient cup storage mechanism 4 and an ingredient cup weighing mechanism 3. On the right side, there is a U-shaped groove for dispensing ingredients from the ingredient tanks. Directly below the U-shaped groove, an ingredient tank conveying mechanism 5 is installed at the bottom of the sheet metal frame 202 to convey ingredients from the tanks. Directly below the ingredient tank conveying mechanism 5, an ingredient tank weighing mechanism 9 is installed. By controlling the ingredient tank conveying mechanism 5, the ingredient tanks are positioned on the ingredient tank weighing mechanism 9 for weighing.

[0020] A mixing mechanism 7 is installed on the right side of the U-shaped trough to agitate the mixing tank after the ingredients have been mixed. A cleaning mechanism 2 for the mixing valve is installed on the left side of the U-shaped trough. After the mixing valve on the integrated storage and mixing raw material tank 8 is used, it moves to the cleaning mechanism 2 to clean the residual fragrance at the valve port, ensuring that the fragrance is not contaminated during the next mixing.

[0021] The raw material tank conveying mechanism 6 is installed at the bottom of the sheet metal frame 202, on one side of the platform 201, above the batching tank conveying mechanism 5. It is responsible for transporting and weighing the integrated raw material tank 8, as well as avoiding the integrated batching tank 10. The batching robot unit 1 is installed on the sheet metal frame 202 in the micro-negative pressure exhaust frame 11, above the raw material tank conveying mechanism 6 and the batching tank conveying mechanism 5.

[0022] Figure 3 This is a schematic diagram of the material handling robot unit of the dual-mode material handling machine provided in this invention. Figure 4 This is a top view of the material handling robot unit structure, combined with... Figure 2 A schematic diagram of the micro-negative pressure exhaust frame shows that the Y-axis linear module 300 is installed on the upper two side beams of the sheet metal frame 202, and two sets of X-axis linear modules 301 are fixed in the middle of the Y-axis linear module 300. Figure 3As shown, the right-side X-axis linear module 301 has a syringe dispensing mechanism 302 and a raw material container clamping mechanism 303 fixed on one side, and a nitrogen injection mechanism 304 fixed on the other side. The left-side X-axis linear module 301 has a dispensing cup pouring mechanism 305 and a solvent adding mechanism 306 fixed on one side, and a dispensing container lid lifting and placing mechanism 307 and a dispensing valve opening mechanism 308 fixed on the other side. The two sets of X-axis linear modules 301 operate independently and can perform dispensing operations simultaneously, improving efficiency.

[0023] When the batching machine performs high-precision, small-volume batching, the raw material tank conveying mechanism 6 transports the integrated storage and batching raw material tank 8 to the batching position. Simultaneously, the Y-axis linear module 300 and X-axis linear module 301 of the batching robot unit 1, in conjunction with the batching cup pouring mechanism 305, move the batching cup to the batching cup weighing position of the batching cup weighing mechanism 3. At the same time, the syringe batching mechanism 302 is moved to the syringe dispensing position of the integrated storage and batching raw material tank 8, where it grips and lifts a suction syringe to extract the raw material. During extraction, negative pressure draws the raw material into the syringe pipette. Then, via the batching robot unit 1, it moves to the batching cup of the batching cup weighing mechanism 3, adding the raw material flavoring into the batching cup, with the batching control performed by the batching cup weighing mechanism 3. The prepared raw materials are then poured into the integrated mixing tank 10 via the dispensing cup pouring mechanism 305. After pouring, the dispensing cup is returned to the dispensing cup weighing mechanism 3. The solvent adding mechanism 306 then adds solvent to clean the dispensing cup, and the cleaned solution is poured into the mixing tank, completing the high-precision small-volume dispensing process.

[0024] When the batching machine performs high-precision, large-range, and medium-range batching, it can use a high-precision batching valve on the integrated storage and batching raw material tank 8 in conjunction with a batching cup and a high-precision, large-range platform scale to perform batching operations. There are two methods: Method 1: The raw material is transported from the integrated storage and batching raw material tank 8 to the batching cup weighing mechanism 3 via the raw material tank conveying mechanism 6 for batching and weighing. The nitrogen injection mechanism 304 on the batching robot unit 1 injects nitrogen into the integrated storage and batching raw material tank 8, creating a slight pressure inside the tank to facilitate the opening of the high-precision batching valve for batching, while the inert nitrogen protects the raw materials inside the tank. On the other side, the high-precision batching valve on the integrated storage and batching raw material tank 8 is opened via the batching valve opening mechanism 308 for batching. The batching cup pouring mechanism 305 pours the prepared flavoring raw materials into the integrated storage and batching batching tank 10. After pouring, the batching cup returns to the batching cup weighing mechanism 3. Next, solvent is added using the solvent adding mechanism 306 to clean the mixing cup. The cleaned solution is then poured into the integrated storage and mixing tank 10, completing high-precision medium-range mixing. Alternatively, the integrated storage and mixing raw material tank 8 is conveyed to the mixing tank feeding position via the raw material tank conveying mechanism 6. The double-precision mixing valve is aligned concentrically with the feeding port of the integrated storage and mixing tank 10 for direct mixing. The mixing is controlled by the mixing tank weighing mechanism 9 below the mixing tank conveying mechanism 5. After mixing, the high-precision mixing valve is removed, completing high-precision large-range mixing.

[0025] After each batching process, the high-precision batching valve of the integrated storage and distribution raw material tank 8 is cleaned by the batching valve cleaning mechanism 2 to ensure that the batching valve is not contaminated. After both batching methods are completed, the raw materials are stirred by the batching tank stirring mechanism 7 next to the integrated storage and distribution batching tank 10.

[0026] Figure 5 This is a right view of the weighing mechanism structure of the dispensing cup of the dual-mode dispensing machine provided in this invention. Figure 6 The diagram shows a disassembled view of the dispensing cup weighing mechanism of the dual-mode dispensing machine. As shown, the dispensing cup weighing mechanism 3 consists of a weighing protection mechanism 501 and a high-precision balance assembly 502. The high-precision balance assembly 502 is installed inside the weighing protection mechanism 501. During dispensing, the dispensing cup weighing mechanism 3 automatically opens the weighing protection mechanism 501, and the dispensing robot unit 1 places the dispensing cup 503 onto the high-precision balance assembly 502 for dispensing.

[0027] Figure 7 This is a schematic diagram of the material handling robot unit of the dual-mode batching machine provided in this invention, combined with... Figure 3Two Y-axis guide rails 707 are provided, respectively installed in the guide rail grooves on the side of the Y-axis crossbeam 701. A Y-axis rack 708 is fixed to the bottom of the Y-axis crossbeam 701. Y-axis mounting seats 704 are fixed on both sides of the Y-axis crossbeam 701 to fix the Y-axis linear module 300. The pulleys of the Y-axis guide rails 707 are fixed at the four corners of the Y-axis sliding plate 702 and are installed on the Y-axis guide rails 707 to form the linear motion component of the Y-axis linear module 300. Y-axis limiting blocks 706 are fixed at both ends of the Y-axis crossbeam 701 and located on both sides of the sliding range of the Y-axis sliding plate 702 to constrain the movement range of the Y-axis linear module 300.

[0028] The X-axis linear module 301 is mounted on the Y-axis sliding plate 702 via an X-axis crossbeam 710. An X-axis reducer 716 is mounted at the bottom center of the X-axis crossbeam 710, which is driven by an X-axis moving motor 715. Gear drive shafts 717 are connected to both sides of the X-axis reducer 716 via couplings, and the other end of the gear drive shafts 717 is connected to the Y-axis transmission assembly 720. A transmission gear 703 is mounted on the other end of the Y-axis transmission assembly 720, which, in conjunction with a Y-axis rack 708 fixed to the bottom of the Y-axis crossbeam 701, provides transmission. An X-axis slider plate motor 713 is mounted at one end of the X-axis crossbeam 710, and a synchronous pulley 719 is installed inside the other end of the X-axis crossbeam 710, which works with a synchronous belt 718. A synchronous belt puller 714 is mounted on the synchronous belt 718 and connected to the back of the X-axis slider plate 711. The X-axis slider plate motor 713 drives the synchronous belt 718 to move, which in turn moves the X-axis slider plate 711. The motion is controlled by the X-axis sensor 712 on the Y-axis slider plate 702. The X-axis guide rail 709 is installed in the guide rail groove on the side of the X-axis beam. The X-axis slider plate 711 is mounted on the X-axis guide rail 709 by pulleys at the four corners, and its motion is guided by the X-axis slider plate 711.

[0029] Figure 8 This is a schematic diagram of the dispensing cup pouring mechanism of the dual-mode dispensing machine according to the present invention. A synchronous pulley 811 is mounted on a lifting servo motor 809 installed on the back of the pouring base 807. A lifting screw 808 is connected to a synchronous belt 810, and both are installed on opposite sides of the pouring base 807. The lifting servo motor 809 drives the synchronous belt 810 to move the lifting screw 808.

26. A method for preparing ingredients, characterized in that, This method uses a syringe-style dispensing method and includes the following steps: When the amount of a single component of raw material is small, the pallet of the integrated storage and distribution batching tank is transported back and forth by the batching tank conveying mechanism and positioned on the large-range batching scale of the batching tank weighing mechanism to carry out the weighing and tare operation of the batching tank before batching. The integrated storage and distribution raw material tank pallet is transported left and right by the raw material tank conveying mechanism to the batching position. The Y-axis linear module and X-axis linear module of the batching robot mechanism work together with the batching cup pouring mechanism to take out the batching cup from the storage mechanism and transport it to the small-range batching scale of the batching cup weighing mechanism for weighing and tareing the batching cup before batching. The syringe dispensing mechanism grabs the syringe and draws raw material from the raw material tank, moves it above the dispensing cup to dispense a small amount of raw material, and stops dispensing when the amount of raw material reaches the weight set and controlled by the weighing mechanism of the dispensing cup, and then dispenses the next batch of raw material. If the maximum capacity of the mixing cup is reached during the filling process, the mixing cup pouring mechanism will automatically grab the mixing cup and pour the raw materials into the mixing tank. Then, the mixing cup will be placed back on the small-range mixing scale for filling again until all raw materials have been filled. The solvent adding mechanism automatically adds solvent to the dispensing cup and cleans the dispensing cup with the solvent. After cleaning, the dispensing cup pouring mechanism adds the tail material to the dispensing tank, completing the high-precision small-volume dispensing in syringe mode.

A method for preparing ingredients, characterized in that, This method employs a dual-precision dispensing valve mode, utilizing a high-precision dispensing valve on the raw material tank and a small-range dispensing scale on the dispensing cup weighing mechanism and a large-range dispensing scale on the dispensing tank weighing mechanism for high-precision medium-range dispensing and high-precision large-range dispensing. The method includes the following steps: (1) When the amount of raw material in a single component is medium: The integrated storage and distribution batching tank pallet is transported back and forth by the batching tank conveying mechanism and positioned onto the large-range batching scale of the batching tank weighing mechanism for weighing and tareing the batching tank before batching. The integrated storage and distribution raw material tank pallet is transported left and right by the raw material tank conveying mechanism and positioned at the dispensing position of the dispensing cup weighing mechanism, located directly above the dispensing cup filling port; The Y-axis linear module and X-axis linear module of the batching robot mechanism work together with the batching cup pouring mechanism to take out the batching cup from the storage mechanism and transport it to the small-range batching scale of the batching cup weighing mechanism for weighing and tareing the batching cup before batching. The nitrogen filling mechanism automatically connects to the nitrogen filling check valve of the integrated storage and distribution raw material, and adds constant pressure nitrogen into the raw material tank. The batching valve opening mechanism automatically connects to the high-precision batching valve on the raw material tank. After the valve is opened, the raw materials in the raw material tank are added to the feeding cup through the feeding valve under nitrogen pressure. The feeding stops when the amount of raw materials reaches the weight set and controlled by the weighing mechanism of the feeding cup, and then the next batch of raw materials is added. If the maximum capacity of the mixing cup is reached during the filling process, the mixing cup pouring mechanism will automatically grab the mixing cup and pour the raw materials into the mixing tank. Then, the mixing cup will be placed back on the small-range mixing scale for filling again until all raw materials have been filled. The solvent adding mechanism automatically adds solvent to the dispensing cup and cleans the dispensing cup with the solvent. After cleaning, the dispensing cup pouring mechanism adds the tail material to the dispensing tank, completing the high-precision medium-range dispensing in the dual-precision dispensing valve mode. (2) When the amount of a single component raw material is large: The integrated storage and distribution batching tank pallet is transported back and forth by the batching tank conveying mechanism and positioned onto the large-range batching scale of the batching tank weighing mechanism for weighing and tareing the batching tank before batching. The integrated storage and distribution raw material tank pallet is transported left and right by the raw material tank conveying mechanism and positioned at the dispensing position of the weighing mechanism of the batching tank, located directly above the filling port of the batching tank; The nitrogen filling mechanism automatically connects to the nitrogen filling check valve of the integrated storage and distribution raw material, and adds constant pressure nitrogen into the raw material tank. The batching valve opening mechanism automatically connects to the high-precision batching valve on the raw material tank. After the valve is opened, the raw materials in the raw material tank are directly added to the batching tank under nitrogen pressure through the batching valve. The addition stops when the batching amount reaches the weight set and controlled by the weighing mechanism of the batching tank, and then the next batch of raw materials is added until all raw materials are added. The solvent adding mechanism automatically adds solvent to the mixing tank, completing high-precision, large-scale mixing in the dual-precision mixing valve mode.
