[0023] The principles and features of the present utility model are described below with reference to the accompanying drawings. The examples given are only used to explain the present utility model and are not intended to limit the scope of the present utility model.

[0024] It should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "linkage" in the terminology should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For those of ordinary skill in the art, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0025] As Figure 1 and Figure 2 shown in the figure, the powder stirring and mixing device of the present utility model includes a frame 1; a stirring tank 2 is installed on the frame 1, and a feeding box 3 is located directly above the stirring tank 2; a feeding hopper 4 is installed at the bottom of the feeding box 3 and is directly opposite to the upper material port of the stirring tank 2; a crushing mechanism 5 for crushing caked powder is installed in the feeding box 3, and a stirring mechanism 6 for fully mixing the powder is installed in the stirring tank 2.

[0026] Specifically, the crushing mechanism 5 includes two sets of oppositely arranged driving rollers 5.1, and crushing knives 5.2 are arranged outside the driving rollers 5.1.

[0027] The crushing mechanism 5 is designed to pre-treat the powder during the feeding process, especially to crush the possible caked parts. This mechanism is mainly composed of two sets of oppositely arranged driving rollers 5.1, which are installed in parallel at a certain distance to ensure that the powder can be effectively processed when passing through.

[0028] Crushing knives 5.2 are arranged outside each driving roller 5.1. These crushing knives usually adopt a sharp edge design to cut and crush the caked parts in the powder when the driving roller rotates. The shape and arrangement of the crushing knives are carefully designed to ensure that the caked parts can be effectively crushed during the crushing process and the normal powder particles can be avoided from being overly damaged.

[0029] Gears 5.3 that mesh with each other are provided at one end of the same side of the two sets of driving rollers 5.1, and one set of driving rollers 5.1 is connected to an external motor driving mechanism.

[0030] Gears 5.3 that mesh with each other are provided at one end of the same side of the two sets of driving rollers 5.1. This design enables the other set of driving rollers to be driven to rotate passively through the meshing action of the gears when one set of driving rollers is driven to rotate by an external motor driving mechanism, so as to realize the synchronous reverse rotation of the two sets of driving rollers. This rotation mode helps to generate shear force and extrusion force during the crushing process, further improving the crushing effect.

[0031] The stirring mechanism 6 includes a stirring shaft 6.1, stirring blades 6.2 are installed on the stirring shaft 6.1, and its input end is connected to a motor driving member 6.3.

[0032] In this embodiment, the equipment is mainly supported by the frame 1, on which a mixing tank 2 and a feeding box 3 are installed. The feeding box 3 is located directly above the mixing tank 2 and is used to store the powder medicine to be mixed, and the powder is introduced into the mixing tank 2 through the feeding hopper 4 at the bottom.

[0033] Before the powder enters the mixing tank 2, it first passes through the crushing mechanism 5 in the feeding box 3. The crushing mechanism 5 is designed to identify and crush the caked parts in the powder, ensuring that the powder particles entering the mixing tank are uniform and there are no large lumps, which is beneficial to the subsequent mixing process.

[0034] Once the powder enters the mixing tank 2, the mixing mechanism 6 is immediately started. The mixing mechanism 6 rotates under the drive of the motor through the mixing shaft 6.1 and the mixing blades 6.2 inside it, generating a strong mixing effect. This mixing effect enables the powder to flow, collide and mix fully in the mixing tank, ensuring that the powder medicine can be mixed evenly and sufficiently to achieve the expected mixing effect.

[0035] As an embodiment, the mixing tank 2 is rotatably connected to the frame 1, and a discharge pipe 2.1 is also installed on one side of the mixing tank 2. A telescopic cylinder 7 connected to the mixing tank 2 is installed on the frame 1; a guiding slope 8 located below the discharge pipe 2.1 is also provided on the frame 1; a control valve is also installed on the discharge pipe 2.1, and the control valve installed on the discharge pipe 2.1 is used to control the discharge speed and flow rate of the powder.

[0036] The mixing tank 2 and the frame 1 are connected in a rotatable manner, which allows the mixing tank to tilt or rotate within a certain range. The main purpose of this design is to facilitate the discharging operation of the powder. After mixing is completed, by adjusting the tilting angle of the mixing tank, the powder can be discharged smoothly through the discharge pipe 2.1, reducing the possibility of residue and blockage.

[0037] The telescopic cylinder 7 installed on the frame 1 is connected to the mixing tank 2 and is used to provide power to adjust the tilting angle of the mixing tank. The telescopic movement of the telescopic cylinder can accurately control the tilting degree of the mixing tank, thereby ensuring that the powder can be discharged at the best angle and speed. In addition, the telescopic cylinder also has a certain buffering and stabilizing effect, which can prevent the mixing tank from shaking violently or being damaged during the tilting process.

[0038] On the frame 1, the guiding slope 8 located below the discharge pipe 2.1 plays a role in guiding the flow direction of the powder. When the powder is discharged from the discharge pipe, the guiding slope can ensure that the powder flows in a predetermined direction, avoiding the powder from scattering everywhere or accumulating around the equipment. This not only helps to keep the production environment clean, but also improves the discharging efficiency and accuracy.

[0039] It should be noted that in this text, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent in such a process, method, article or device. Unless otherwise clearly specified and defined, the terms "install", "connect" and "couple" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
