[0002] Aluminum-plastic composite panels (also known as aluminum-plastic panels) are a new type of decorative material. Since they were introduced to China from Germany in the late 1980s and early 1990s, they have quickly gained popularity due to their cost-effectiveness, diverse color options, convenient construction methods, excellent processing performance, superb fire resistance and noble quality. Raw material mixing is a key step in the production process of aluminum-plastic panels, involving the uniform mixing of various raw materials.

[0025] Working principle: When using the mixer with the spiral limiting structure, the feeding port 14 first inputs the aluminum-plastic plate raw material into the inside of the mixing barrel 1, and then the distance sensor 18 monitors the height of the raw material in real time. When it is detected that the raw material has reached the preset position, the controller controls the feeding mechanism to stop feeding or controls the alarm device to alarm to remind the staff to stop feeding. Secondly, the controller controls the stirring motor 11 to energize and work, and drives the connecting cylinder 8 to rotate through the second transmission gear 13 and the first transmission gear 9, and then drives the scraper 7 and the stirring rod 6 to rotate to stir the raw materials. Secondly, after the stirring and covering are completed, the controller controls the discharge motor 4 to energize and work to drive the spiral auger 3 to rotate inside the discharge barrel 2, and discharge the stirred raw materials from the discharge port 5. Then the controller controls the electric push rod 10 to work and push the scraper 7 to move downward. In the process of the scraper 7 moving downward, the raw materials attached to the inner wall of the mixing barrel 1 and the raw materials attached to the stirring rod 6 are scraped off and discharged. This is the working principle of the mixer with the spiral limiting structure.
