[0022] To fully understand this invention, a detailed structure will be presented in the following description to illustrate the technical solution proposed by this invention. Optional embodiments of the invention are described in detail below; however, in addition to these detailed descriptions, the invention may have other embodiments.
[0023] Please see Figures 1-2A pharmaceutical raw material mixing device includes a mixing chamber 1. The top of the mixing chamber 1 has multiple inlets 2, each containing a flow sensor 3. An electromagnetic valve 4 is located at the outlet of each inlet 2. A rotary motor 5 is located in the center of the top of the mixing chamber 1. The output end of the rotary motor 5 is connected to a first rotating shaft 6. One end of the first rotating shaft 6 is fixedly connected to a support rod 7. Both ends of the support rod 7 are equipped with electric telescopic rods 8. The output end of the electric telescopic rods 8 is connected to a scraper 9. A motor housing 10 is fixedly installed at the bottom of the mixing chamber 1. A stirring motor 11 is fixedly installed inside the motor housing 10. A second rotating shaft 12 is fixedly connected to the output end of the stirring motor 11. The second rotating shaft 12 movably penetrates the bottom outer wall of the mixing chamber 1 and extends into the interior of the mixing chamber 1. Multiple stirring rods are fixedly connected to the outer walls on both sides of the second rotating shaft 12. The flow sensor 3, rotary motor 5, electric telescopic rods 8, and stirring motor 11 are all connected to a controller signal.
[0024] For example, the present invention provides a pharmaceutical raw material mixing device, the working principle of which is as follows: First, the top of the mixing chamber 1 has multiple inlets 2, each inlet 2 containing a flow sensor 3 and a solenoid valve 4. The amount and speed of raw material input can be controlled to ensure that different materials are added precisely in proportion. Different materials can include mixtures of powders or mixtures of powders and liquids. The flow sensor 3 monitors the flow rate, and the solenoid valve 4 switches on and off according to signals, automatically adjusted by the controller to prevent too much or too little raw material from entering, thus improving the accuracy of pharmaceutical formulation.
[0025] The bottom has a motor housing 10 with a built-in stirring motor 11, which is connected to a second rotating shaft 12. The shaft has multiple stirring rods of increasing length. Stirring rods of different lengths can stir different spaces, making the stirring more uniform. The stirring motor 11 drives the stirring rods to rotate, ensuring uniform mixing.
[0026] Next, a rotary motor 5 is located at the top center, connected to a first rotating shaft 6. One end of the shaft has a support rod 7, and both ends of the support rod 7 are equipped with electrically operated telescopic rods 8. These electric telescopic rods 8 are synchronously controlled by a controller and operate simultaneously. A scraper 9 is connected to the end of each electric telescopic rod 8. This scraper 9 is used to promptly clean the inner wall of the mixing chamber 1 after mixing and discharging, preventing material adhesion and waste. In particular, the rotary motor 5 drives the scraper 9 to rotate, and the electric telescopic rods 8 can move up and down to adjust the position of the scraper 9, adapting to materials of different heights or viscosities. The scraper 13 can more effectively remove residue.
[0027] Specifically, one end of the scraper 9 is provided with a scraper adhesive 13.
[0028] For example, the adhesive 13 can fit more closely to the inner wall of the box, and it is less likely to scratch the inner wall of the box during cleaning.
[0029] Specifically, the lengths of the plurality of stirring rods increase sequentially from top to bottom.
[0030] Specifically, a rotating sealing ring 14 is provided at the connection between the second rotating shaft 12 and the bottom outer wall of the mixing box 1.
[0031] For example, rotating the sealing ring 14 prevents material leakage and ensures a tight seal.
[0032] Specifically, the mixing box has a discharge port 16 on one side of its bottom.
[0033] For example, the discharge port 16 is located on the bottom side, and the mixture is discharged after it is mixed.
[0034] Specifically, the bottom of the mixing box is provided with support legs 17 on both sides, which provide stability.
[0035] It should be noted that the flow sensor 3, rotary motor 5, electric telescopic rod 8, stirring motor 11 and controller used in the above embodiments are all conventional electronic components that are known to those skilled in the art. Their specific connection circuits and how to select specific models are common knowledge that is known to those skilled in the art. The above embodiments will not be described in detail.
[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
