[0038] By adopting the above technical solution, when in use, the dietary raw materials to be prepared are respectively added to each raw material cylinder 12, and sufficient water is added to the proportioning water tank 11. The operation of the entire device can be controlled by the central controller 10. The central controller 10 includes an electronic touch control screen embedded in the front end surface of the carrying box 1. The names and proportion values ​​of the raw materials such as protein raw materials, carbohydrate raw materials, fat raw materials, vitamins and mineral raw materials to be prepared are input into the working system of the central controller 10 through the electronic touch control screen. The control central controller 10 can be connected to the hospital's HIS system through Bluetooth or 5G network to identify dietary prescriptions. When preparing, the valve of the corresponding valve tube 13 of the raw material cylinder 12 is opened, so that The raw materials in the raw material barrel 12 can flow into the weighing component 9 through the valve tube 13, and the weighing component 9 can realize the weighing processing of multiple raw materials; the weighing component 9 pours the weighed raw materials into the mixing collection box 709, and starts the servo motor 301. The servo motor 301 can drive the driving shaft 4 to rotate in the forward direction, and the forward rotation of the driving shaft 4 can drive the driving push rod 701 to rotate. When the driving push rod 701 rotates to the corresponding position of the rotating transmission push rod 702, the arc slope of the transmission push rod 702 and the arc slope of the top of the driving push rod 701 rotate and squeeze, thereby pushing the transmission push rod 702 to move upward, and the upward movement of the transmission push rod 702 can drive the oscillation push rod 703 to move upward, and the upward movement of the oscillation push rod 703 can promote the mixing and collection When the driving push rod 701 is separated from the transmission push rod 702, the oscillating push rod 703 will move downward under the action of the baffle 704 and the return spring 705, pushing the transmission push rod 702 to move downward. At the same time, the mixed collection box 709 will move downward under the contraction force of the buffer spring 710 without the action of the upward thrust. During the process of up and down extension and contraction, the buffer spring 710 will drive the mixed collection box 709 to vibrate up and down, thereby facilitating the mixed collection. The raw materials in the collection box 709 are mixed, and the vibration mixing action of the mixing component 7 can ensure that the raw materials are fully dispersed and evenly mixed in the mixing collection box 709; compared with the traditional stirring method, the mixing component 7 can more thoroughly break up the agglomeration and caking between the raw materials, so that the various ingredients are more evenly distributed in the mixture, and this highly uniform mixing helps to ensure the consistency and stability of the nutritional components of the final product; and the vibration mixing of the mixing component 7 usually has a faster mixing speed, and can achieve the ideal mixing effect in a shorter time; this is of great significance to improving production efficiency; in addition, rapid mixing can also reduce the risk of degradation and deterioration of the raw materials during the mixing process, ensuring the quality and safety of the product.The vibration mixing method of the mixing component 7 is applicable to various types of raw materials, including powdered, granular and liquid materials; this wide applicability enables the medical nutritional meal preparation machine to prepare various nutritionally balanced meal products as needed to meet the nutritional needs of different patients. When the servo motor 301 drives the driving shaft 4 to rotate in the forward direction, the driving shaft 4 can drive the ratchet group 302 to rotate in the forward direction, and the gear of the ratchet group 302 is meshed with the driven gear 303, so as to drive the driving shaft 304 to rotate. The cooperation between the driving shaft 304 and the driven shaft 305 can drive the conveyor belt 306 to rotate, and the meal collection bottle 6 to be contained in the nutritious meal is placed in the assembly hole 307. The conveyor belt 306 can drive the meal collection bottle 6 to move to the connecting pipe 712 through the assembly hole 307. With the cooperation of the driving limit assembly 8, the meal collection bottle 6 moves to the connecting pipe 712, and the connecting pipe 712 is opened to connect with the meal collection bottle 6, so that the meal can be transported to the meal collection bottle 6. The oscillation mixing assembly 5 is arranged at an upper position of the horizontal center line of the conveyor belt 306, so as to prevent the oscillation plate 505 from causing oscillation and knocking on the lower side of the conveyor belt 306 when the driving shaft 4 rotates in the forward direction. When the meal collection bottle 6 on the conveyor belt 306 continuously moves to the oscillation plate 505, the servo motor 301 works to drive the drive shaft 4 to rotate in the opposite direction, and the drive shaft 4 can drive the transmission lever 501 to rotate. When the transmission lever 501 rotates, it will collide with the transmission rod 502, thereby driving the transmission rod 502 to rotate a certain angle. When the transmission rod 502 rotates, it can drive the oscillation transmission shaft 503 to rotate the same angle. The oscillation transmission shaft 503 can drive the oscillation plate 505 to rotate upward, so that the oscillation plate 505 can knock and vibrate the bottom end of the meal collection bottle 6 through the knocking hole 308, thereby further vibrating and mixing the meal collected in the meal collection bottle 6. In this way, the relative movement and contact opportunities between the materials can be increased through the two oscillations of the mixing component 7 and the oscillation mixing component 5, so that the materials can undergo convection, diffusion and shear mixing in a wider area, thereby improving the uniformity of mixing. This helps to ensure that various nutrients are evenly distributed in the meal and improve the nutritional intake effect of the patient. For some materials that are easy to clump or aggregate, two oscillations can more effectively break up lumps and agglomerates, and improve the fluidity and dispersibility of the materials. This helps to reduce the granularity in the meal, improve the taste and digestion and absorption effect. The design of two oscillations of the mixing component 7 and the oscillation mixing component 5 can adapt to materials of different types and properties. Whether it is solid powder, liquid or semi-solid material, effective mixing can be achieved by adjusting the oscillation parameters. This improves the versatility and flexibility of the equipment.

[0039] Specifically, Figures 5 to 7As shown, a limiting slide groove 801 is provided inside the carrying box body 1 above the conveying channel 2, a slide 802 is slidably installed inside the limiting slide groove 801, a pulley 803 is rotatably installed above the slide 802, and a limiting ring 804 is fixedly installed on the bottom end of the side wall of the slide 802; a fixed seat 805 is fixed on the inner wall of the carrying box body 1 above the conveying channel 2, a sealing baffle 806 is rotatably installed on the upper end surface of the fixed seat 805, a positioning shaft 808 is installed at the connection between the sealing baffle 806 and the fixed seat 805, and a tension spring 807 is fixedly installed on the side wall of the sealing baffle 806. The weighing assembly 9 includes a driving motor 901 fixedly mounted on the inner wall of the assembly cavity 711, the output end of the driving motor 901 is fixedly connected to a load-bearing shaft 902, a load-bearing pallet 903 is fixedly mounted in the middle position of the load-bearing shaft 902, a weighing tray 904 is fixedly mounted on the upper end surface of the load-bearing pallet 903, and a proportioning water tank 11 is connected to the assembly cavity 711 through a water pipe and a water valve, and the end of the water pipe is located above the weighing tray 904. The addition of water and the order of adding dietary ingredients can be regulated according to the central controller 10 as required.

[0040] By adopting the above technical solution, the raw materials in the raw material barrel 12 flow into the weighing tray 904 through the valve tube 13. The weighing tray 904 can transmit the weighing data to the central controller 10 through the wire in the form of an electrical signal. When the weighing value reaches a predetermined threshold, the valve tube 13 is closed to complete the weighing of a single raw material. When the weighing of a single raw material is completed, the drive motor 901 is started. The drive motor 901 can drive the load-bearing shaft 902 to rotate, and the load-bearing shaft 902 can drive the load-bearing support plate 903 to rotate. The load-bearing support plate 903 can flip the parallel weighing tray 904, so that the raw materials in the weighing tray 904 fall into the corresponding mixed collection box 709, so that the weighing processing of multiple raw materials can be realized. When placing the meal collection bottle 6 into the assembly hole 307, it is necessary to sleeve the limiting ring 804 on the outside of the meal collection bottle 6, and insert the slide 802 into the limiting slide groove 801. At this time, the moving meal collection bottle 6 can drive the slide 802 to slide in the limiting slide groove 801 through the pulley 803, so as to ensure the stability of the meal collection bottle 6 during the movement, thereby playing an auxiliary fixing effect on the meal collection bottle 6 during the movement, and significantly enhancing the stability of the meal collection bottle 6 during the movement. Since the meal collection bottle 6 is usually loaded with food or drinks, these substances may shake due to inertia when moving, causing the bottle to tilt or even fall. The design of the limiting ring 804 effectively prevents this shaking through physical restrictions, ensuring the stability of the bottle when moving. Stable movement reduces the risk of damage or spillage of the contents due to shaking, especially for meals that are fragile, easy to spill, or need to maintain a specific temperature such as hot or cold drinks. This protection is particularly important. When the slide 802 moves to the sealing baffle 806, the continuous movement of the slide 802 can push the sealing baffle 806 to rotate, and the sealing baffle 806 can rotate on the fixed seat 805 through the positioning shaft 808, so that the bottom end of the sealed connecting pipe 712 can be opened, so that the connecting pipe 712 can be connected with the meal collection bottle 6, and the meal can be transported to the meal collection bottle 6. At this time, the conveying component 3 stops running, so that the meal collection bottle 6 has sufficient time to collect the meal. After the collection is completed, the conveying component 3 drives the meal collection bottle 6 to move, and the slide 802 pushes the sealing baffle 806 to rotate the moving angle, and then separates from the sealing baffle 806. The sealing baffle 806 is elastically reset by the tension spring 807 and returns to the initial state, thereby sealing the outlet of the connecting pipe 712. In this way, by driving the limit assembly 8 to cooperate with the meal collection bottle 6, the delivery amount and time of the meal can be accurately controlled to ensure the accurate delivery of the meal. The operator only needs to simply move the meal collection bottle 6 to the designated position, and the slide 802 can automatically open the sealing baffle 806 and transport the meal, which is easy and quick to operate; and the automated operation reduces direct contact between people and meals, reduces the risk of cross contamination, and ensures the hygiene and safety of meals.

[0041] Working principle: When in use, the dietary raw materials to be prepared are added into each raw material cylinder 12 respectively, and sufficient water is added to the proportioning water tank 11. The operation of the entire device can be controlled by the central controller 10, and the proportional value to be prepared is input into the working system of the central controller 10. When preparing, the valve corresponding to the valve tube 13 of the raw material cylinder 12 is opened, so that the raw materials in the raw material cylinder 12 can flow into the weighing component 9 through the valve tube 13. The weighing tray 904 can transmit the weighing data to the central controller 10 through the wire in the form of an electrical signal. When the weighing value reaches a predetermined threshold, the valve tube 13 is closed to complete the weighing of a single raw material. When the weighing of a single raw material is completed, the drive motor 901 is started, and the drive motor 901 can drive The bearing shaft 902 rotates, and the bearing shaft 902 can drive the bearing support plate 903 to rotate. The bearing support plate 903 can flip the parallel weighing tray 904, so that the raw materials in the weighing tray 904 fall into the corresponding mixing collection box 709, so that the weighing processing of various raw materials can be realized, and the servo motor 301 is started. The servo motor 301 can drive the driving shaft 4 to rotate forward. The forward rotation of the driving shaft 4 can drive the driving push rod 701 to rotate. When the driving push rod 701 rotates to the corresponding position of the driving push rod 702, the arc slope surface of the driving push rod 702 and the arc slope surface at the top of the driving push rod 701 rotate and squeeze, thereby pushing the driving push rod 702 to move upward. The upward movement of the driving push rod 702 can drive the oscillation push rod 703 to move upward, and the oscillation push rod 703 The rod 703 moves upward to push the mixed collection box 709 to move upward in the assembly cavity 711, which can drive the buffer spring 710 to extend. At the same time, when the oscillation push rod 703 moves upward, it will push the baffle 704 to move upward. When the baffle 704 moves, it will compress the return spring 705 in the assembly groove 708. When the driving push rod 701 is separated from the transmission push rod 702, the oscillation push rod 703 will move downward under the action of the baffle 704 and the return spring 705, pushing the transmission push rod 702 to move downward. At the same time, the mixed collection box 709 will move downward under the contraction force of the buffer spring 710 without the action of upward thrust. In the process of up and down expansion and contraction, the buffer spring 710 will drive the mixed collection box 709 to vibrate up and down. And it is convenient to mix the raw materials in the mixing and collecting box 709. The vibration mixing effect of the mixing component 7 can ensure that the raw materials are fully dispersed and evenly mixed in the mixing and collecting box 709. When the servo motor 301 drives the driving shaft 4 to rotate forward, the driving shaft 4 can drive the ratchet group 302 to rotate forward, and the gear of the ratchet group 302 is meshed with the driven gear 303, so as to drive the driving shaft 304 to rotate. The mutual cooperation between the driving shaft 304 and the driven shaft 305 can drive the conveyor belt 306 to rotate, and the meal collection bottle 6 to be filled with nutritious meals is placed in the assembly hole 307. The conveyor belt 306 can drive the meal collection bottle 6 to move to the connecting pipe 712 through the assembly hole 307. When the meal collection bottle 6 is placed in the assembly hole 307,At the same time, it is necessary to sleeve the limiting ring 804 on the outside of the meal collection bottle 6, and insert the slide 802 into the limiting slide groove 801. At this time, the moving meal collection bottle 6 can drive the slide 802 to slide in the limiting slide groove 801 through the pulley 803. When the slide 802 moves to the sealing baffle 806, the continuous movement of the slide 802 can push the sealing baffle 806 to rotate. The sealing baffle 806 can rotate on the fixed seat 805 through the positioning shaft 808, so that the bottom end of the sealed connecting pipe 712 can be opened, so that the connecting pipe 712 can be connected with the meal collection bottle 6, and the meal can be transported to the meal collection bottle 806 is in the bottle 6, at this time, the conveying component 3 stops running, so that the meal collection bottle 6 has sufficient time to collect the meal. After the meal is collected, the conveying component 3 drives the meal collection bottle 6 to move, and the slide 802 pushes the sealing baffle 806 to rotate the moving angle and separates from the sealing baffle 806. The sealing baffle 806 is reset by the elasticity of the tension spring 807 and returns to the initial state, thereby sealing the outlet of the connecting pipe 712. The oscillating and mixing component 5 is located above the horizontal center line of the conveyor belt 306, so as to avoid the oscillating plate 505 from causing oscillation and knocking on the lower side of the conveyor belt 306 when the driving shaft 4 rotates in the forward direction. When the meal collection bottle 6 on the 6 continues to move to the oscillation plate 505, the servo motor 301 works to drive the driving shaft 4 to rotate in the opposite direction, and the driving shaft 4 can drive the transmission lever 501 to rotate. When the transmission lever 501 rotates, it will collide with the transmission rod 502, thereby driving the transmission rod 502 to rotate a certain angle. When the transmission rod 502 rotates, it can drive the oscillation transmission shaft 503 to rotate at the same angle. The oscillation transmission shaft 503 can drive the oscillation plate 505 to rotate upward, so that the oscillation plate 505 can knock and vibrate the bottom end of the meal collection bottle 6 through the knocking hole 308, thereby further oscillating the meal collected in the meal collection bottle 6. Vibration mixing treatment is performed. When the drive shaft 4 rotates in the reverse direction, the drive shaft 4 cannot drive the ratchet set 302 to rotate in the reverse direction, and thus the conveyor belt 306 will not be driven to rotate in the reverse direction. At the same time, when the drive shaft 4 rotates in the reverse direction, it will also drive the driving top rod 701 to rotate in the reverse direction. The driving top rod 701 and the transmission top rod 702 are squeezed, so that the transmission top rod 702 rotates in the limited rotation groove 706 through the rotating shaft 707, and no longer drives the oscillation push rod 703 to move up and down. When the device completes the meal preparation, the hot water in the proportioning water tank 11 can be added to the device again, and the hot water circulates in the device to achieve automatic cleaning and disinfection of the device.
