[0027] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0028] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0029] See also Figure 1-Figure 9 A portable medical formula food weight and ingredient precision calibration device comprises a mixing box 1, a first feeding mechanism 2, a second feeding mechanism 3, a stirring component 4 and a discharge port, wherein the first feeding mechanism 2 and the second feeding mechanism 3 are both arranged at the upper part of the mixing box 1, the stirring component 4 is arranged inside the mixing box 1 for stirring and mixing food, and the discharge port is arranged at the lower part of the mixing box 1; the first feeding mechanism 2 is used for feeding liquid ingredients, and the first feeding mechanism 2 comprises a first feeding hopper 21, a first feeding trough 22 and a And a first flipping assembly 23, the first loading trough 22 is located at the lower part of the first loading hopper 21, and the first flipping assembly 23 is used to flip the first loading trough 22; the second feeding mechanism 3 is used for solid ingredient feeding, and the second feeding mechanism 3 includes a second loading hopper 31, a second loading trough 32 and a second flipping assembly 33, the second loading trough 32 is located at the lower part of the first loading hopper 21, and the second flipping assembly 33 is used to flip the second loading trough 32, and weighing sensors 5 are provided in the first loading trough 22 and the second loading trough 32.

[0030] The operating principle of the precise calibration device of the present invention is: The operator loads the liquid ingredients and the solid ingredients respectively through the first loading mechanism 2 and the second loading mechanism 3. The liquid ingredients enter the first loading trough 22 through the first loading hopper 21. The weighing sensor 5 monitors the weight of the added ingredients in real time and feeds back the weight information to the system. When the added ingredients reach the preset value, the operator is prompted to stop feeding. At this time, the first flipping component 23 flips the first loading trough 22, so that the liquid ingredients in the first loading trough 22 enter the mixing box 1, completing the loading operation of the first loading mechanism 2; the solid ingredients enter through the second loading hopper 31. In the second feeding chute 32, the weighing sensor 5 monitors the weight of the added ingredients in real time and feeds back the weight information to the system. When the added ingredients reach the preset value, the operator is prompted to stop feeding. At this time, the second flipping component 33 flips the second feeding chute 32 to allow the solid ingredients in the second feeding chute 32 to enter the mixing box 1, completing the feeding operation of the second feeding mechanism 3; after the liquid ingredients and the solid ingredients are added in place, the stirring component 4 starts to work to stir and mix the ingredients to ensure that the ingredients are fully and evenly mixed; after mixing is completed, the final food formula is output through the discharge port.

[0031] Since the weighing sensor 5 is arranged in the first feeding trough 22 and the second feeding trough 32, during the batching process, only the set amount of ingredients need to be used, and the first flipping mechanism and the second flipping mechanism will pour all the weighed ingredients into the mixing box 1, ensuring the full use of the ingredients and reducing the waste in the precise proportioning process of the ingredients; by setting the weighing sensor 5 and the flipping mechanism, it is ensured that only the set amount of ingredients are used in each batching process, avoiding excessive use or waste; the weighing sensor 5 can accurately monitor the weight of the ingredients, and cooperate with the flipping mechanism to pour all the weighed ingredients into the mixing box 1, ensuring that each ingredient is accurately added to the food formula according to the required proportion; although different ingredients may have different shapes, densities and other characteristics, the cooperation of the weighing sensor 5 and the flipping mechanism can ensure the consistency and stability of each batching.

[0032] At the same time, by weighing and feeding separately through different channels, precise control of solid ingredients and liquid ingredients can be achieved. The weighing sensor 5 set in each ingredient channel can accurately monitor the amount of each ingredient, ensure the accuracy and consistency of the formula, and improve the quality and stability of food processing; the split channel design separates the supply paths of liquid and solid ingredients, which facilitates the cleaning and maintenance of the equipment, avoids the problem of difficulty in cleaning after mixing different types of ingredients, and helps to keep the equipment hygienic and clean; by weighing and feeding separately through channels, the batching of solid and liquid ingredients can be carried out at the same time, improving the efficiency of medical food preparation. Weighing and feeding separately also reduces the complexity of the device, improves the portability of the batching device, simplifies the operation process, and is conducive to the rapid progress of the medical food preparation process.

[0033] See also Figure 2 , Figure 3 and Figure 5 In order to reduce the impact of residual ingredients and ensure the quality and accuracy of subsequent ingredients, in one embodiment, a first material guide valve 24 is arranged between the first loading hopper 21 and the first loading trough 22, a liquid collecting box 6 and a water tank 7 are arranged on the mixing box 1, a first collecting pipe 25 is arranged between the liquid collecting box 6 and the first loading trough 22, a water spray pipe 26 is arranged between the water tank 7 and the first loading trough 22, and a pressure pump is arranged between the first collecting pipe 25 and the water spray pipe 26.

[0034] The first material guide valve 24 is located between the first loading hopper 21 and the first loading trough 22 to control the amount of liquid ingredients discharged. The weight of the liquid ingredients in the first loading trough 22 is monitored by the weighing sensor 5. The first material guide valve 24 is connected to the weighing sensor 5 for communication. The switch is adjusted as needed to avoid excessive discharge of ingredients and ensure the accuracy and stability of ingredients. The liquid collection box 6 and the water tank 7 are used to store liquid ingredients and cleaning water respectively. When the first loading trough 22 is cleaned, the pressure pump sprays the water in the water tank 7 into the first loading trough 22 through the water spray pipe 26 to rinse the remaining ingredients. The liquid and residual ingredients after flushing are introduced into the liquid collecting box 6 through the first collecting pipe 25 to complete the cleaning of the first loading trough 22; the pressure pump increases the water pressure, ensuring that the water spray pipe 26 effectively flushes the residual ingredients in the first loading trough 22, and introduces the flushing liquid into the first loading trough 22 to ensure the cleanliness of the first loading trough 22. The above settings can effectively control the discharge amount of liquid ingredients, clean and flush the first loading trough 22, reduce the impact of residual ingredients, and ensure the quality and accuracy of subsequent ingredients through synergistic effect.

[0035] See also Figure 2 and Figure 4In order to avoid cross contamination between different ingredients and ensure the purity of raw materials in the preparation process of medical formula food, in one embodiment, a second material guide valve 34 is provided between the second upper hopper 31 and the second upper trough 32, a solid material collection box 8 is provided on the mixing box 1, a second material collection pipe 35 is provided between the solid material collection box 8 and the second upper trough 32, and a pressure pump is provided on the second material collection pipe 35. A second material guide valve 34 is provided between the second upper trough 32 and the second upper hopper 31, and its function is to control the discharge amount of solid ingredients. The valve is communicatively connected to the weighing sensor 5 and can be adjusted as needed to ensure that the required solid ingredients enter the second loading trough 32 in the correct proportion, thereby avoiding excessive or insufficient feeding. After the flipping mechanism flips the second loading trough 32 for feeding, the second collecting pipe 35 and the pressure pump adsorb the solid raw materials remaining in the second loading trough 32 into the solid collecting pipe, thereby achieving the cleaning of the second loading trough 32. By thoroughly cleaning the second loading trough 32, the mixing of ingredients from different batches and the contamination of residual impurities can be avoided, thereby ensuring that the quality of the prepared medical formula food meets the standards. Timely cleaning of the second loading trough 32 can avoid cross-contamination between different ingredients, thereby ensuring the purity of raw materials during the preparation of medical formula foods. Keeping the second loading trough 32 clean can reduce the cleaning time when changing batches of ingredients, save medical food preparation time, and improve the preparation efficiency of medical formula foods. By absorbing the solid ingredients remaining in the second loading trough 32 into the solid collecting pipe, the waste of raw materials can be minimized and costs can be saved.

[0036] See also Figure 2 and Figure 7 In order to better disperse and mix the ingredients together and effectively prevent the ingredients from agglomerating or adhering to the inner wall of the mixing box 1, in one embodiment, a jet assembly 9 is further provided on the inner wall of the mixing box 1. The jet assembly 9 includes air holes 91, air pipes and air pumps. The air holes 91 are distributed in an array on the inner wall of the mixing box 1. The air holes 91 are connected to the air pump through the air pipes. The jet direction of the air holes 91 is toward the horizontal tangent direction of the stirring of the stirring assembly 4. The jet assembly 9 can make the raw materials in the mixing box 1 more fully mixed by spraying air into the mixing box 1. The movement and action of the airflow help to better mix the raw materials with each other, ensuring uniform mixing quality; the action of the jet assembly 9 can accelerate the mixing speed of the raw materials in the mixing box 1, making the mixing process faster and more efficient. The stirring action of the airflow can improve the mixing efficiency and save the time of batching; the action of the airflow can make the ingredients better dispersed and mixed together, thereby improving the uniformity of mixing. This helps to ensure that each component is evenly distributed in the mixture, avoiding the occurrence of local uneven concentration; the jet assembly 9 can effectively prevent the ingredients from agglomerating in the mixing box 1 or adhering to the inner wall of the box. The airflow can separate the raw materials, avoid agglomeration, and ensure the smooth progress of the mixing process.

[0037] See also Figure 2 and Figure 5 In order to evenly guide the mixed food to the discharge port and reduce the residual substances in the mixing box 1, in one embodiment, a gathering plate 10 is provided on the inner bottom surface of the mixing box 1. The gathering plate 10 is tilted, and the tilted lower part of the gathering plate 10 guides the mixed food to the discharge port. A vibration motor 11 is provided at the bottom of the gathering plate 10. The gathering plate 10 provided at the bottom of the mixing box 1 is tilted, and mainly through the tilt angle and the vibration motor 11 at the bottom, the mixed food is evenly guided to the discharge port. When stirring and mixing is carried out in the mixing box 1, the mixed food will gradually flow downward along the inclined surface of the gathering plate 10. The vibration force generated by the vibration motor 11 can help the medical formula food to move better on the gathering plate 10, thereby promoting the uniform mixing of the mixture; by designing a reasonable inclination angle and the effect of vibration force, the mixed food can flow smoothly to the discharge port, reducing the time that the food stays in the box, effectively shortening the medical food preparation cycle, and improving the medical food preparation efficiency; the inclination setting of the gathering plate 10 and the operation of the vibration motor 11 help to control the time and speed of the mixing process. When the food is mixed to a certain degree, the design of the gathering plate 10 and the action of the vibration motor 11 can guide the mixed food to the discharge port in time, avoiding excessive mixing of the ingredients, thereby ensuring the quality of the medical formula food; utilizing the gathering plate 10 and the vibration motor 11, the mixed food can be effectively guided to the discharge port, reducing the residual material in the mixing box 1 and reducing the cost of cleaning and maintenance; the inclined design of the gathering plate 10 and the action of the vibration motor 11 can promote the flow of the mixed food, ensuring that the mixture can be fully contacted and stirred during the mixing process, improving the mixing efficiency and ensuring the mixing quality.

[0038] See also Figure 2 and Figure 4In order to realize multiple calibration processes and make the batching flow more accurate and stable, in one embodiment, a coarse material guide pipe 36 and a fine material guide pipe 37 are arranged between the second loading hopper 31 and the second loading trough 32, and the second material guide valve 34 includes a first discharge valve 341 and a second discharge valve 342, the first discharge valve 341 is arranged on the coarse material guide pipe 36, and the second discharge valve 342 is arranged on the fine material guide pipe 37.

[0039] See also Figure 2 and Figure 6In order to reduce the stratification phenomenon between ingredients and ensure that different types of ingredients are fully mixed, in one embodiment, a scraper assembly 12 is provided on the upper end surface of the gathering plate 10. The scraper assembly 12 includes a connecting shaft 121 and a rotating plate 122. The rotating plate 122 is rotatably mounted on the connecting shaft 121 and rotates along the gathering plate 10. The scraper assembly 12 is used to clean the ingredients adhered to the gathering plate 10. During the preparation of medical formula food, some ingredients are easily left on the surface of the gathering plate 10 due to their strong adhesion. If they are not cleaned in time, the ingredients will accumulate on the gathering plate 10, affecting the mixing efficiency and food quality. The rotation of the rotating plate 122 can effectively clean the surface of the gathering plate 10, push the adhered ingredients to one side or scrape them off, and ensure the cleanliness and purity of the ingredient mixing; through the action of the scraper assembly 12, the mixed ingredients can be effectively prevented from accumulating on the gathering plate 10. The rotation of the rotating plate 122 can push the ingredients to one side, avoid excessive accumulation or accumulation of ingredients, maintain the uniform distribution of ingredients, and help reduce the waste of ingredients; the movement of the scraper assembly 12 can help improve the mixing uniformity of ingredients. Through the rotation of the rotating plate 122, the ingredients can be evenly distributed on the gathering plate 10, reducing the stratification phenomenon between ingredients, ensuring that different types of ingredients are fully mixed, helping to improve the quality and consistency of medical food preparation, and ensuring that the product meets the ingredient ratio and quality standards required by the design; the function of the scraper assembly 12 can improve the efficiency of the medical food preparation line. By continuously cleaning the ingredients, preventing accumulation and improving the mixing uniformity, the scraper assembly 12 can ensure the stable flow of ingredients during the medical food preparation process and improve the food mixing efficiency.

[0040] See also Figure 8 and Fig. 9In order to prevent the ingredients from falling directly into the mixing box 1 and ensure the accuracy of the measurement of the weighing sensor 5, in one embodiment, the first flip assembly 23 and the second flip assembly 33 both include a cylinder 13, a connecting arm 14 and a rotating shaft 15, and the first loading chute 22 and the second loading chute 32 are both rotatably mounted on the connecting arm 14 through the rotating shaft 15, and the connecting arm 14 is mounted on the telescopic end of the cylinder 13.

During the feeding process, the cylinder 13 is compressed so that the first feeding trough 22 and the second feeding trough 32 are both engaged in the limiting groove. At this time, the materials passing through the first feeding hopper 21 and the second feeding hopper 31 all fall into the first feeding trough 22 and the second feeding trough 32 respectively. After the weighing sensor 5 detects that the indication is stable, the cylinder 13 is stretched to make the first feeding trough 22 and the second feeding trough 32 move downward and disengage from the limiting groove. The motor drives the rotating shaft 15 to drive the first feeding trough 22 and the second feeding trough 32 to flip over, and introduce the materials in the first feeding trough 22 and the second feeding trough 32 into the mixing box 1 to realize subsequent mixing operations.

The air hole 91 in the jet assembly 9 is arranged on the inner wall of the mixing box 1, connected to the air pump through the air pipe, and the jet direction is toward the horizontal tangent direction of the stirring assembly 4. When the air pump is working, the air flow is sprayed into the mixing box 1 through the air pipe and the air hole 91, forming an air flow dynamic, which prompts the raw materials in the mixing box 1 to be quickly stirred, mixed and evenly distributed. Such a design can effectively shorten the mixing time and improve the mixing efficiency, thereby accelerating the medical food preparation process; the water tank 7 is arranged at the lower part of the gathering plate 10, the air pipe is connected to the water tank 7, and a water pump is arranged. After the mixing is completed, the water pump can be used to supply water to the air pipe, sprayed through the air hole 91, and the inner wall of the mixing box 1 is sprayed with water for cleaning. This water spray cleaning function can effectively remove residual materials and dirt in the mixing box 1, keep the mixing box 1 clean and hygienic, avoid cross contamination and improve the cleanliness of the mixing space; the jet assembly 9 accelerates the mixing process and the water spray cleaning function, improves the mixing efficiency, shortens the time consumed by mixing and cleaning, and reduces the waiting time for cleaning during mixing. At the same time, the cleanliness of the equipment and the uniformity of the mixing of the raw materials are maintained, which helps to save maintenance and cleaning costs. The water tank 7 is arranged at the lower part of the material gathering plate 10, which realizes the full utilization of the space of the mixing box 1 and improves the compactness of the spatial structure of the mixing box 1.

[0042] See also Figure 2 and Figure 7 In order to ensure that the ingredients are fully mixed and stirred, and to ensure the quality and uniformity of the mixture, in one embodiment, the stirring assembly 4 includes a motor, a stirring shaft 41 and a stirring paddle 42. The stirring paddle 42 is staggered on the stirring shaft 41. The motor drives the stirring shaft 41 to rotate. The stirring shaft 41 is provided with two groups, which are respectively located at the lower part of the first feeding trough 22 and the second feeding trough 32. The first feeding trough 22 and the second feeding trough 32 are used to introduce the ingredients into the mixing box 1. By providing two groups of stirring shafts 41, each group of stirring shafts 41 is located at the lower part of different feeding troughs, it can be ensured that the ingredients are fully mixed and stirred. When the stirring paddle 42 rotates, the ingredients will be effectively stirred, pushed and mixed, so that different ingredients are evenly mixed, ensuring the quality and uniformity of the mixture; by setting the stirring shaft 41 at the position of different feeding troughs, it can ensure that different types of ingredients are fully mixed, reducing the occurrence of partial uneven mixing. The staggered distribution design of the stirring paddle 42 allows the ingredients to cover a wider range during the stirring process, ensuring the uniformity and consistency of the mixing.
