[0021] The present invention has the following beneficial effects:

[0022] 1. For the raw material mixing device and process for preparing a functional film, by arranging a blanking plate in the mixing tank, through holes are formed in the blanking plate, and the raw materials enter the mixing tank through the feeding port and can continue to fall into the mixing tank through the through holes. The blanking plate divides the inside of the mixing tank to limit the falling speeds of the solid raw materials and the liquid raw materials, avoiding the driving resistance generated when falling into the bottom of the mixing tank at the same time, reducing the energy consumption required for the mixing driving force, and performing mixing in multiple small amounts, so as to ensure sufficient mixing;

[0023] 2. For the raw material mixing device and process for preparing a functional film, by arranging a driving component, an eccentric wheel is connected to one end of the driving shaft away from the motor, and the eccentric wheel drives and rotates in the support block through the driving shaft.

[0024] 3. For the raw material mixing device and process for preparing a functional film, through the forward / reverse motor, the driving shaft is driven to rotate. By the meshing of the first gear and the first rack, the first rack is driven to lift and lower in the mixing tank. At the same time, a second gear is installed at one end of the stirring shaft, and a second rack is arranged on the inner wall of the mixing tank. The second gear and the second rack are meshed. Therefore, the rotation of the stirring shaft drives the stirring blades to rotate in the mixing tank, thus realizing the stirring function of the stirring shaft in the mixing tank. By the lifting and lowering of the first rack in the mixing tank and the rotation of the stirring shaft, the contact area with the raw materials is increased, and the mixing effect of this stirring component is improved;

[0025] 4. For the raw material mixing device and process for preparing a functional film, by arranging a sliding rod at the top of the first rack, one end of the sliding rod is pin-connected with a connecting rod through a pin joint seat, and the other end of the connecting rod away from the pin joint seat is pin-connected with a dial plate with bristles.

[0026] 5. For the raw material mixing device and process for preparing a functional film, by arranging a knocking component at the top of the first rack, the first rack is lifted and lowered to drive the ejector rod and the roller to knock the bottom surface of the blanking plate. The ejector rod is pin-connected to one side of the first rack through a torsion spring and a connecting seat.

A guide sleeve (36) is installed at the position where the sliding rod (30) penetrates in the blanking plate (29). A second spring (31) is arranged between the sliding rod (30) and the guide sleeve (36).

8. A raw material mixing device for preparing a functional film according to claim 7, characterized in that: One side of the top end of the sliding rod (30) is connected with a pin joint seat (35). A connecting rod (32) is pin-jointed in the pin joint seat (35). One end of the connecting rod (32) is pin-jointed with a dial plate (33) with bristles. The dial plate (33) is slidably connected with the blanking plate (29). Limit strips (34) are arranged on the upper surface of the blanking plate (29). The dial plate (33) is slidably connected with the limit strips (34).

9. The raw material mixing device for preparing a functional film according to claim 1, characterized in that: A knocking component is arranged on the top of the first rack (22). The knocking component includes a connecting seat (39). The connecting seat (39) is fixedly connected with the first rack (22). A ejector rod (38) is pin-jointed in the connecting seat (39) through a pin shaft (41). A torsion spring (40) is arranged on the surface of the pin shaft (41). A roller (37) is arranged at one end of the ejector rod (38) away from the connecting seat (39).

10. A process, including a raw material mixing device for preparing a functional film as described in any one of claims 1-9, comprising the following steps, characterized in that: Step 1: The solid raw material and the liquid raw material are conveyed into the mixing tank (1) through the feeding port (2). Part of the solid raw material stays on the blanking plate (29). The liquid raw material can enter the bottom of the mixing tank (1) more quickly relative to the solid raw material. Step 2: Start the driving component to drive the mixing tank (1) to lift and lower in the support ring (3) to promote the falling of the solid raw material. Step 3: The driving component drives the stirring component to mix the raw materials in the mixing tank (1). At the same time, the stirring component drives the dial plate (33) at the top to move horizontally back and forth, further promoting the raw materials to fall to the bottom of the mixing tank (1) for full mixing.
