[0013] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the utility model.

[0014] Those skilled in the art should understand that, in the disclosure of the specification, the orientation or position relationship indicated by the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0015] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0016] refer to Figure 1 A liquid silicone mixing device according to a preferred embodiment of the present invention will be described in detail below, wherein the liquid silicone mixing device comprises a mixing shell 10, a central mixing tube 20 and at least two feeding tubes 30, wherein in some cases, such as when only components A and B need to be mixed, there are two feeding tubes 30, wherein in other cases, such as when components A, B and C need to be mixed at the same time, there are three feeding tubes 30, wherein the mixing shell 10 is provided with a first end cover 11 and a discharge port at the top and bottom of the mixing shell 10, respectively. 101, and the central mixing tube 20 vertically penetrates the first end cover 11 in a rotatable manner and extends into the shell cavity 102 of the mixing shell 10, wherein the portion of the central mixing tube 20 located outside the mixing shell 10 is defined as the external tube 21, and the portion located inside the shell cavity 102 is defined as the internal tube 22, wherein the side wall of the internal tube 22 is evenly provided with a discharge port 202 connected to the tube cavity 201 of the central mixing tube 20, and the side wall of the internal tube 22 is circumferentially provided with stirring teeth 23 to stir the mixture generated by the mixing shell 10. In addition, a bearing 24 is embedded in the top pipe opening of the outer pipe 21, and a second end cover 25 is fixedly embedded in the inner ring of the bearing 24, wherein the conveying pipe 30 vertically penetrates the second end cover 25 and extends into the tube cavity 201, and the bottom end of the conveying pipe 30 is located above the discharge port 202. In this way, after the material transported by the conveying pipe 30 enters the tube cavity 201, it will be thrown out from the discharge port 202 into the shell cavity 102 under the action of the rotating centrifugal force. As the central mixing pipe 20 continues to rotate, the material is discharged from the shell cavity 102. As the shell 102 continues to rotate, the stirring teeth 23 also continue to rotate, thereby fully mixing the materials in the shell cavity 102. As a result, the materials transported by different feed pipes 30 are first gathered in the tube cavity 201 and mixed to a certain extent during the rotation process. Secondly, there is also a certain degree of mixing in the process of being thrown out under the action of centrifugal force. Finally, there is also a certain degree of stirring and mixing under the rotation of the stirring teeth 23. Compared with conventional stirring and mixing, the mixing effect is better and the mixing is more uniform. At the same time, the mixing efficiency is improved, which can fully meet the production needs of the enterprise.

[0017] During the rotation of the central mixing tube 20 , the second end cover 25 cooperates with the central mixing tube 20 via the bearing 24 . Therefore, the second end cover 25 does not rotate with the central mixing tube 20 , and thus the multiple feed pipes 30 do not rotate.

[0018] In one embodiment, the liquid silicone mixing device further includes a rotating motor 40. The output shaft of the rotating motor 40 is coaxially sleeved with a driving wheel 41, and the outer tube 21 is coaxially sleeved with a driven wheel 26, and the driving wheel 41 and the driven wheel 26 are connected by a transmission member 42, so that the central mixing tube 20 can be driven to rotate by the cooperation of the rotating motor 40, the driving wheel 41 and the driven wheel 26, wherein the transmission member 42 can be a transmission belt or a transmission chain.

[0019] In one embodiment, the mixing shell 10 is provided with a control valve suitable for controlling the discharge at the discharge port 101, which is used to control the discharge port 101 to open after a predetermined mixing time to discharge the mixed materials.

[0020] In one embodiment, the stirring teeth 23 include middle stirring teeth 231 and bottom stirring teeth 232, wherein in the height direction, the middle stirring teeth 231 are close to the middle of the internal tube 22, and the bottom stirring teeth 232 are located at the bottom of the internal tube 22, and the discharge port 202 near the top is located above the middle stirring teeth 231, so that the coordination of the middle stirring teeth 231 and the bottom stirring teeth 232 can further improve the mixing effect of the materials and shorten the mixing time.

[0021] Further preferably, the bottom stirring tooth 232 is provided with a curved portion 2321 and a parallel portion 2322, wherein the extension direction of the parallel portion 2322 is the same as the extension direction of the central mixing tube 20, and is close to the middle stirring tooth 231 and the side wall of the shell cavity 102, so that the material thrown out by the centrifugal force can be directly stirred and mixed at a position close to the top, and this part of the material basically falls gradually outward and obliquely downward in the form of a parabola, wherein the curved portion 2321 is connected to the bottom end of the parallel portion 2322 and the bottom end of the central mixing tube 20 at both ends in an arc-shaped manner, thereby cooperating with the parallel portion 2322 to receive and stir and mix the material in the entire shell cavity, thereby ensuring the mixing quality of the material.

[0022] It should be noted that the terms "first, second" in the present invention are only used for descriptive purposes and do not indicate any order. They cannot be understood as indicating or implying relative importance. These terms can be interpreted as names.

[0023] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
