The top and bottom of the stirring shell 11 are respectively provided with a feed pipe 14 and a discharge pipe 15 communicating with its own inner cavity. The discharge pipe 15 is connected to a discharge valve 16. The feed pipes 14 are evenly distributed along the circumference of the stirring shell 11.
[0040] Drive component 2 drives the stirring shaft 12 to rotate;
[0041] The diffusion assembly 3 includes a diffusion shell 31 fixed directly above the stirring shell 11. The diffusion shell 31 contains horizontally spaced diffusion cavities distributed along the vertical direction. The outer wall of the diffusion shell 31 is fixed with feeding pipes 32 that are connected to the diffusion cavities one by one and are upward. The bottom wall of each diffusion cavity protrudes downward and has a corresponding dropping pipe 33 that is set directly above the feeding pipe 14. Along the vertical direction, there is a dropping gap between adjacent dropping pipes 33, and the dropping pipe 33 at the bottom is connected to the corresponding feeding pipe 14.
[0042] The on / off assembly 4 includes a connecting pipe 41 that corresponds one-to-one with the dropping pipe 33 and is sealed to the inner wall of the dropping pipe 33 in the circumferential direction, and a lifting unit 42 that drives the connecting pipe 41 to move in the vertical direction between the connecting position and the disconnecting position.

In the disconnecting position, the connecting port 411 is separated from the dropping gap and the diffusion cavity.
[0043] The device uses initially, the communication pipe 41 is moved to the disconnected position by the lifting unit 42, so that the communication port 411 is separated from the material falling gap and the diffusion cavity, so that the production raw material particles of the heat insulation strip are put into the diffusion cavity through the feeding pipe 32 after the diffusion cavity of the diffusion shell 31 is separated, in the utility model, the diffusion cavity and the feeding pipe 32 are all provided with four, four diffusion cavities are used for temporarily storing basic resin material, reinforcing material, filler and additive respectively, of course, according to the different types of heat insulation strips, the number of diffusion cavities can be determined according to the type and number of heat insulation strip production raw materials, for example, when six kinds of production raw materials are needed for the heat insulation strip, the number of diffusion cavities in the diffusion shell 31 is designed to be six.
[0044] According to the production ratio, after different types of production raw material particles are put into and stored in the diffusion cavity through the feeding pipe 32, the lifting unit 42 in the on-off assembly 4 is operated, the communication pipe 41 is adjusted to the communication position, so that the communication port 411 on the communication pipe 41 is communicated with the material falling gap at this position, at this time, the material in the diffusion cavity enters the inner cavity of the communication pipe 41 through the communication port 411 from the material falling gap, and then falls along the inner cavity of the communication pipe 41, and then enters the feeding pipe 14 through each material falling pipe 33, and then enters the stirring shell 11 through the feeding pipe 14, and then the driving assembly 2 drives the stirring shaft 12 and the stirring plate 13 to rotate, so that the material particles diffused in the stirring shell 11 are mixed uniformly.
[0045] Because the feeding pipe 14 is distributed along the circumference of the stirring shell 11 at equal intervals, and the material falling pipe 33 at the bottom of the diffusion cavity corresponds to the feeding pipe 14 one by one, so that the material in the diffusion cavity can be uniformly diffused everywhere, and then falls through the communication pipe 41, and then enters the stirring shell 11 from the feeding pipe 14, so that the multiple different materials are uniformly diffused downward from multiple positions at the top of the stirring shell 11, and then the driving assembly 2 drives the stirring shaft 12 and the stirring plate 13 to rotate, so that the different particle materials diffused and distributed uniformly are mixed and stirred, so that the mixing uniformity and the mixing efficiency are improved, the same kind of material is avoided to be connected, the time required for mixing and uniformity is increased, and because the uniformity of the mixed different materials is improved, the production quality of the heat insulation strip after heating and forming is improved.
