Description

Technical Field

[0001] The utility model relates to the technical field of homogenizing heads, in particular to a homogenizing head for an emulsifying machine. Background Art

[0002] An emulsifier is a device that combines stirring, homogenizing, crushing, and dissolving. Through the high-speed rotation of the homogenizing head connected to the engine, it shears, disperses, and impacts the material, making it more delicate and promoting the blending of oil and water. It is widely used in cosmetics, shower gels, sunscreens, and many other creams. An emulsifier consists of an emulsifying tank and an emulsifying homogenizing head installed within the tank. The emulsifying homogenizing head consists of a rotor and a stator. Under the action of the stator, the stator and rotor create a combined effect of intense, reciprocating hydraulic shear, friction, centrifugal extrusion, and liquid collision in a narrow gap. The material circulates through this working process in the container to obtain the final product.

[0003] However, the rotor of the existing emulsifying homogenizing head consists of a hollow column and three square blades. The gaps between the three square blades are large, and the material residence time is short, resulting in low material fineness. If the standard is to be met, a long emulsification time is required, and the quality is unstable in large-scale production. Utility Model Content

[0004] The purpose of the utility model is to design a homogenizing head for an emulsifier, which can achieve a long residence time of the material in the rotor when being sheared, a short emulsification time, and a high degree of fineness and uniform texture of the emulsified material, and good quality stability in large-scale production, so as to solve the problems raised by the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A homogenizing head for an emulsifier includes a stator and a rotor. The stator is a cylinder with an open bottom end. A plurality of first discharge channels are provided on the cylinder at intervals along the circumferential direction. The rotor is arranged in the cylinder and connected to a motor outside the emulsification tank via a rotating shaft. The rotor includes a fixed seat, a hollow column, and at least two layers of cutting knife rings. The hollow column is mounted on the fixed seat, and the at least two layers of cutting knife rings are arranged in an alternating manner.

[0007] Furthermore, the cutting knife ring includes a plurality of knife blocks, and the plurality of knife blocks are arranged at intervals around the central axis of the hollow column and installed on the fixing seat.

[0008] Furthermore, the cross section of the blade block is a regular polygon.

[0009] Furthermore, the cross section of the blade block is an irregular polygon.

[0010] Furthermore, the first discharge channel is a through hole.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] By providing at least two layers of cutting rings, the material enters the rotor through openings at one end of the rotor and stator, respectively. The stator remains stationary, while the rotor rotates, driving the cutting rings within it. This forces the material out of the second discharge channel and into the gap between the rotor and stator for cutting and emulsification. The staggered arrangement of at least two layers of cutting rings allows for at least two cuts, significantly improving the emulsification effect. The material also retains a longer residence time, resulting in a finer material. To meet standards, a shorter emulsification time is required, ensuring stable quality during mass production. Once cutting and emulsification are complete, the material is discharged through the first discharge channel on the stator. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0019] Example 1

[0020] Please refer to Figure 1A homogenizing head for an emulsifier includes a stator 1 and a rotor 2. The stator 1 is a cylinder with an open bottom end. A plurality of first discharge channels 3 are provided on the cylinder at intervals along the circumferential direction. The first discharge channels 3 are through holes. The sheared material is discharged through the first discharge channels 3. Since a certain pressure is required to extrude the material from the through hole, the residence time of the material in the rotor 2 is increased. The rotor 2 is arranged in the cylinder and connected to the motor outside the emulsification tank via a rotating shaft. When the motor is started, the rotating shaft and the rotor 2 are driven to rotate, performing a comprehensive effect of shearing, friction, centrifugal extrusion, and liquid flow collision. The rotor 2 includes a fixed seat 4, a hollow column 5, and two layers of cutting knife rings 6. The hollow column 5 is mounted on the fixed seat 4, and the two layers of cutting knife rings 6 are staggered. The cutting knife ring 6 includes a plurality of knife blocks 7. The cross-section of the knife block 7 is a regular polygon. The plurality of knife blocks 7 are arranged and mounted on the fixed seat 4 at intervals around the central axis of the hollow column 5. The material enters rotor 2 through the openings at one end of the rotor 2 and stator 1, respectively. Stator 1 remains stationary, while rotor 2 rotates, driving the cutting ring 6 within it. This pushes the material out of the second discharge channel and into the gap between rotor 2 and stator 1 for cutting and emulsification. The staggered arrangement of the two layers of cutting rings 6 allows them to pre-cut and complete the material, greatly improving the emulsification effect. The extended material residence time ensures a finer material texture. To meet standards, a shorter emulsification time is required, ensuring stable quality during mass production. Once cutting and emulsification are complete, the material is discharged through the first discharge channel 3 on stator 1.

[0021] Example 2

[0022] Please refer to Figure 2A homogenizing head for an emulsifier includes a stator 1 and a rotor 2. The stator 1 is a cylinder with an open bottom. Multiple first discharge channels 3 are spaced apart along the circumference of the cylinder. The first discharge channels 3 are through-holes through which the sheared material is discharged. Since a certain amount of pressure is required to squeeze the material out of the through-holes, the material's residence time in the rotor 2 is increased. The rotor 2 is housed within the cylinder and connected to a motor outside the emulsifying tank via a rotating shaft. When the motor is activated, the rotating shaft and the rotor 2 rotate, producing a combination of shearing, friction, centrifugal extrusion, and liquid collision effects. The rotor 2 includes a fixed seat 4, a hollow column 5, and three-layer cutting knife rings 6. The hollow column 5 is mounted on the fixed seat 4, and the three-layer cutting knife rings 6 are staggered. The cutting knife rings 6 include multiple blade blocks 7, each with an irregular polygonal cross-section. The multiple blade blocks 7 are spaced apart around the central axis of the hollow column 5 and mounted on the fixed seat 4, thereby increasing the shear force of the homogenizing head and improving the fineness and skin feel of the material. The material enters rotor 2 through openings at one end of the rotor 2 and stator 1, respectively. Stator 1 remains stationary, while rotor 2 rotates, driving the cutting ring 6 within it. This pushes the material out of the second discharge channel and into the gap between rotor 2 and stator 1 for cutting and emulsification. The three layers of cutting rings 6 are staggered, allowing them to pre-cut and complete the material, greatly improving the emulsification effect. The extended material residence time ensures a finer material texture. To meet standards, a shorter emulsification time is required, ensuring stable quality during mass production. Once cutting and emulsification are complete, the material is discharged through the first discharge channel 3 on stator 1.

[0023] The working principle of this embodiment is as follows: During use, the rotating shaft drives the emulsifying and homogenizing head to rotate, and the material enters rotor 2 through the openings at one end of the rotor 2 and stator 1. Stator 1 remains stationary, and the rotation of rotor 2 drives the cutting ring 6 inside it to rotate, thereby pushing the material out of the second discharge channel and into the gap between rotor 2 and stator 1 for cutting and emulsification. When the cutting and emulsification is complete, the material is discharged through the first discharge channel 3 on stator 1. The working process is as follows.
