Weighing sensors 32 are distributed around the lower end of the bottom plate 31 and are installed on the upper end of the first annular plate 21 through the weighing sensors 32 for detecting the weight of the ingredients. The batching assembly is provided in several groups along the mixing tank 3. The batching assembly includes a batching tank 4 and a screw feeder 41 located at the lower end of the batching tank 4. The outer end of the screw feeder 41 is provided with a bending cylinder 42, which is inserted into the corresponding opening of the mixing tank 3.

[0015] In this embodiment, the first ring plate 21 and the second ring plate 22 are arranged vertically at intervals. The first ring plate 21 and the second ring plate 22 are fixedly connected by a support column 23. The support column 23 extends to the lower end of the second ring plate 22 and is fixedly connected to the upper end cover of the liquid preparation tank 1.

[0016] In this embodiment, the mixing tank 3 is provided with a guide cylinder 33 at the lower end. The guide cylinder 33 is inserted into the guide hole corresponding to the liquid preparation tank 1 and does not contact the inner wall of the guide hole to avoid affecting the weight detection. The mixing tank 3 is provided with a valve control assembly for controlling the opening and closing of the guide cylinder 33. The valve control assembly includes a shaft 5 installed on the mixing tank 3 and a valve block 51 provided at the lower end of the shaft 5. The upper end of the mixing tank 3 is provided with an electric cylinder 52 for driving the shaft 5 to move up and down. The guide cylinder 33 is provided with a valve seat 34 that cooperates with the valve block 51 to fit and seal with the raised valve block 51.

[0017] The electric cylinder 52 is fixedly mounted on the cylinder frame 55 and is fixedly mounted on the upper end of the mixing tank 3 through the cylinder frame 55. The outer end of the output rod of the electric cylinder 52 is fixedly provided with a top plate 56, and the shaft 5 is moved up and down through the top plate 56.

[0018] In this embodiment, when the mixing tank 3 introduces the powder into the liquid preparation tank 1 through the guide cylinder 33, the powder may become clogged in the mixing tank 3 and the guide cylinder 33, and the powder will fall vertically and be unevenly distributed, resulting in low fusion and decomposition efficiency. Therefore, this embodiment provides a mechanism to facilitate the dispersion of powder.

[0019] The mixing tank 3 is provided with a sliding sleeve corresponding to the shaft 5. The top plate 56 is provided with a drive motor 58 that is connected to the shaft 5. The shaft 5 is provided with a spiral blade 59 at the upper end of the valve block 51 to facilitate the smooth introduction of raw materials in the mixing tank 3 into the liquid preparation tank 1. The top plate 56 is provided with guide sleeves on both sides and is slidably mounted on the guide rod 57. The guide rod 57 is vertically installed at the corresponding position of the mixing tank 3 to prevent the top plate 56 from rotating. The top plate 56 is controlled by the electric cylinder 52 to drive the shaft 5 to move up and down.

[0020] The upper end of the valve block 51 is provided with a sealing end face that cooperates with the valve seat 34. The lower end of the valve block 51 is integrally provided with a spray block 53. The spray block 53 has a frustum-shaped structure, and blades 54 are distributed on the inclined end face of the upper end of the spray block 53. The shaft 5 drives the spray block 53 to rotate synchronously. The blades 54 spray the falling powder so that it is evenly dispersed into the liquid mixing tank 1, thereby improving the dissolution efficiency of the powder.

[0021] In this embodiment, the upper end of the screw feeder 41 is connected to the lower end of the feeding pipe of the mixing tank 4 to receive the powder in the mixing tank 4. The lower end of the screw feeder 41 is fixedly installed on the second ring plate 22 by a frame rod. The bending cylinder 42 does not contact the inner wall of the corresponding opening of the mixing tank 3 to avoid affecting the weighing.

[0022] Specifically, various dry powder raw materials are stored in corresponding ingredient tanks 4 and guided into mixing tank 3 by screw feeder 41. When adding dry powder raw materials, electric cylinder 52 controls the top plate 56 to rise, so that the valve block 51 and valve seat 34 cooperate to seal the guide cylinder 33 to prevent the powder from falling. The screw feeder 41 moves to guide the corresponding dry powder raw materials into mixing tank 3. The weighing sensor 32 detects the weight of the added raw materials in real time. Multiple dry powder raw materials are added in sequence to achieve precise control. After the addition is completed, electric cylinder 52 controls the valve block 51 to fall to open the guide cylinder 33. At the same time, the drive motor 58 controls the shaft 5 and the scattering block 53 to rotate. The spiral blades guide the raw materials downward and scatter them through the scattering block 53 to improve the dissolution effect of the dry powder raw materials.
