[0003] Firstly, the mixing structure is relatively simple, making it difficult to achieve sufficient mixing of silicone raw materials, resulting in uneven mixing and affecting the quality stability of silicone products. Furthermore, the high viscosity of melted silicone raw materials further complicates the mixing process.
[0004] To address these issues, this invention provides a silicone raw material mixing and stirring device. Utility Model Content

[0012] Beneficial effects
[0013] This invention provides a mixing and stirring device for silica gel raw materials. Compared with the prior art, it has the following advantages:
[0014] 1. In this silicone raw material mixing and stirring device, when the rotating disc drives the outer plate to rotate, the stirring rod and stirring blade revolve around the center, while the first gear rolls along the inner gear ring to cause the stirring rod and blade to rotate on their own axis. This compound motion greatly increases the complexity of the movement trajectory of the silicone raw material in the heating and mixing box, significantly improves the mixing efficiency of the material, ensures that the raw material can be mixed quickly, fully and evenly, and effectively shortens the mixing time.
[0015] 2. In this silicone raw material mixing and stirring device, while the motor drives the rotating drum to rotate, external gas enters the rotating drum through the air inlet pipe and rotary joint, and is sprayed into the silicone raw material liquid through the one-way nozzle. The airflow disturbance formed by the gas and the mechanical stirring of the stirring blades work together to promote the silicone raw material to move more vigorously in three-dimensional space. This not only further enhances the mixing effect, but also avoids the problem of local accumulation or uneven mixing of raw materials due to excessive viscosity, thus improving the overall quality of silicone raw material mixing.

For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.
[0023] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.
[0024] Reference Figures 1 to 4 This application provides a silicone raw material mixing and stirring device, including a heating mixing chamber 1. An auxiliary component 3 is provided on the top of the heating mixing chamber 1, and a mixing component 2 is provided inside the heating mixing chamber 1. The auxiliary component 3 includes a rotating cylinder 37, which is rotatably connected to the inner top of the heating mixing chamber 1. The mixing component 2 includes a rotating disk 24, which is fixedly installed on the outside of the rotating cylinder 37. An outer side plate 23 is fixedly installed on the outside of the rotating disk 24. A stirring rod 21 is rotatably connected to the bottom of the outer end of the outer side plate 23, and a stirring blade 22 is fixedly installed on the outside of the stirring rod 21.
[0025] Both the stirring rod 21 and the stirring blade 22 are located inside the heating mixing chamber 1. A first gear 25 is rotatably connected to the top of the outer side plate 23. The top of the stirring rod 21 moves through the interior of the outer side plate 23 and is fixedly installed below the corresponding first gear 25. An internal gear ring 26 is fixedly installed at the bottom of the heating mixing chamber 1, and the first gears 25 are all meshed on the inner side of the internal gear ring 26. A feed port 4 is fixedly installed on the outer side of the heating mixing chamber 1, and a discharge valve 5 is fixedly installed at the bottom of the heating mixing chamber 1.
[0026] In this embodiment, when mixing and stirring the silicone raw material, the raw material is fed into the heating mixing chamber 1 through the feeding port 4. The heating mixing chamber 1 heats and melts the raw material. During the heating process, the rotating cylinder 37 rotates, driving the rotating disk 24 to rotate. The rotating disk 24 rotates, driving the outer plate 23 to rotate. The rotation of the outer plate 23 drives the stirring rod 21 and the stirring blade 22 to revolve around the center. During the rotation, the first gear 25 rolls along the inner gear ring 26. The rolling of the first gear 25 along the inner gear ring 26 drives the lower stirring rod 21 and the stirring blade 22 to rotate. By rotating on its own axis while revolving inside the heating mixing chamber 1, the mixing efficiency of the material is improved during heating and mixing, ensuring that the raw material can be mixed better.
[0027] Reference Figures 1 to 4 In one aspect of this embodiment, the auxiliary component 3 includes an air inlet pipe 31, a rotary joint 32 is fixedly installed at the bottom of the air inlet pipe 31, the rotary joint 32 is fixedly installed at the top of the rotating cylinder 37, the air inlet pipe 31 and the rotating cylinder 37 are interconnected through the rotary joint 32, and a one-way nozzle 38 is fixedly installed on the outside of the rotating cylinder 37, the communication direction of the one-way nozzle 38 is from the inside of the rotating cylinder 37 to the outside.
[0028] The rotary joint 32 is divided into upper and lower sections, which are rotatably connected to each other. A bracket 36 is fixedly installed between the upper section of the rotary joint 32 and the heating mixing box 1. A third gear 35 is fixedly installed on the outer side of the lower section of the rotary joint 32. A motor 33 is fixedly installed on the top of the heating mixing box 1. A second gear 34 is fixedly installed on the output end of the motor 33. The second gear 34 and the third gear 35 mesh with each other.
[0029] In this embodiment, during mixing, the rotation of the rotating drum 37 drives the second gear 34 and the third gear 35 to rotate via the motor 33, which in turn drives the lower half of the rotary joint 32 to rotate, thereby driving the lower rotating drum 37 to rotate. The motor 33 provides power for stirring and mixing. During stirring, external gas enters through the air inlet pipe 31 and enters the interior of the rotating drum 37 through the rotary joint 32. The rotary joint 32 ensures gas delivery without affecting the rotation of the rotating drum 37. The gas entering the rotating drum 37 is sprayed out through the one-way nozzle 38 into the silicone raw material liquid being mixed inside. The introduction of gas can create airflow disturbance in the heating mixing chamber 1, which, in conjunction with the mechanical stirring action of the stirring blades 22, promotes the silicone raw material to move more violently in three-dimensional space, thereby better mixing the raw material.
[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0031] Working principle: During the mixing and stirring of silicone raw materials, the raw materials are fed into the heating and mixing chamber 1 through the feeding port 4. The heating and mixing chamber 1 heats and melts the raw materials. During the heating process, the rotating cylinder 37 rotates, driving the rotating disk 24 to rotate. The rotating disk 24 then drives the outer plate 23 to rotate. The rotation of the outer plate 23 causes the stirring rod 21 and stirring blades 22 to revolve around the center. During rotation, the first gear 25 rolls along the inner gear ring 26, which in turn drives the lower stirring rod 21 and stirring blades 22 to rotate. The stirring blades 22 rotate simultaneously within the heating and mixing chamber 1, thereby improving the mixing efficiency of the materials during heating and mixing, ensuring better mixing of the raw materials. During mixing, the rotation of the rotating drum 37 drives the second gear 34 and the third gear 35 to rotate via the motor 33, which in turn drives the lower half of the rotary joint 32 to rotate, thereby driving the rotating drum 37 below to rotate. The motor 33 provides power for stirring and mixing. During stirring, external gas enters through the air inlet pipe 31 and enters the interior of the rotating drum 37 through the rotary joint 32. The rotary joint 32 ensures gas delivery without affecting the rotation of the rotating drum 37. The gas entering the rotating drum 37 is sprayed out through the one-way nozzle 38 into the mixed silica gel raw material liquid inside. The introduction of gas can create airflow disturbance in the heated mixing chamber 1, which, together with the mechanical stirring action of the stirring blades 22, promotes the silica gel raw material to move more vigorously in three-dimensional space, thereby better mixing the raw material.
