[0021] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Reference Figures 1 to 5 This utility model provides a technical solution: a foaming and mixing device for producing foam nose bridge strips for face masks, including a base 5, a mixing tank 13 on the top of the base 5, and U-shaped frames 9 symmetrically arranged on both sides of the mixing tank 13 and fastened to the base 5. A sliding seat 10 is raised and lowered inside the U-shaped frame 9. A second electric push rod 7 is vertically connected inside the U-shaped frame 9, and the top of the second electric push rod 7 is fastened to the sliding seat 10. To improve the stability of the sliding seat 10 sliding up and down, a guide rod 6 parallel to the second electric push rod 7 is vertically connected inside the U-shaped frame 9, and the guide rod 6 passes through the sliding seat 10. When the sliding seat 10 slides, under the guidance of the guide rod 6, the sliding seat 10 can be ensured to slide stably in a straight line.

[0023] like Figure 2 , 3 As shown, the mixing tank 13 is rotatably connected to the sliding seat 10 via a rotating shaft, and a mounting box 8 is connected to the outer wall of one of the sliding seats 10. A driven gear 20 is coaxially fastened on the rotating shaft on one side of the mixing tank 13, and a third motor 21 is fixedly connected inside the mounting box 8. A driving gear 22 is coaxially connected to the output end of the third motor 21. The driving gear 22 and the driven gear 20 are meshed. The third motor 21 drives the driving gear 22 to rotate, which in turn drives the driven gear 20 to rotate synchronously. This allows the mixing tank 13 to rotate and adjust along the rotating shaft on its outer wall, which facilitates the feeding of the mixed raw materials.

[0024] like Figure 1 , 4As shown in Figure 5, in order to improve the mixing efficiency of raw materials in the mixing tank 13, a rotating seat 23 is rotatably connected inside the mixing tank 13, and a stirring rod 14 is connected to the outer wall of the rotating seat 23. At the same time, in order to facilitate the installation and disassembly of the stirring rod 14, a mounting cover 24 is connected to the top of the rotating seat 23, and the stirring rod 14 is fastened to the outer wall of the mounting cover 24, and the side wall of the stirring rod 14 and the inner wall of the mixing tank 13 are fitted with a clearance.

[0025] Meanwhile, a fixed seat 19 is rotatably connected to the base 5, and a second motor 18 is fixedly connected to the bottom of the base 5. The output ends of the fixed seat 19 and the second motor 18 are connected. A retaining seat 11 is provided at the bottom of the rotating seat 23, and a retaining groove 4 is opened at the top of the fixed seat 19. The mixing tank 13 is located directly above the retaining groove 4. The retaining seat 11 and the retaining groove 4 are engaged. After the mixing tank 13 descends to the top of the fixed seat 19, the retaining seat 11 and the retaining groove 4 are engaged, and the fixed seat 19 can be driven to rotate by the second motor 18, which in turn drives the stirring rod 14 inside the mixing tank 13 to rotate, thus realizing the rapid mixing of raw materials inside the mixing tank 13.

[0026] like Figure 1 , 2 As shown, in order to further improve the efficiency of raw material mixing, a first motor 16 is connected to the top side of the base 5 via a lifting mechanism. The lifting mechanism includes a support seat 2 vertically connected to the top of the base 5. A bracket 1 is slidably connected inside the support seat 2. The bracket 1 and the support seat 2 are U-shaped structures arranged in opposite directions. A first electric push rod 3 is vertically connected between the bracket 1 and the support seat 2. A connecting shaft 15 extending into the mixing tank 13 is connected to the output end of the first motor 16. Multiple stirring blades 12 are connected to the lower outer wall of the connecting shaft 15.

[0027] In summary, when the foaming and mixing device for producing mask nose bridge strips is in use, the first motor 16 drives multiple stirring blades 12 to rotate within the mixing tank 13. The stirring blades 12 and the stirring rod 14 rotate in opposite directions, which further improves the efficiency and quality of raw material mixing. In addition, to further facilitate the movement of the device, four wheels 17 are connected to the bottom corners of the base 5. The wheels 17 are braked swivel wheels, which greatly facilitates the use of the device.
