Description

Technical Field

[0002] Rubber materials are widely used in our daily lives, from car tires to medical devices to seals for various electronic products. However, how to prepare rubber materials with excellent performance and strong durability has always been an important issue in the field of materials science. In the traditional rubber preparation process, double-roll extrusion is a commonly used technology. This technology uses two rotating rollers to extrude the rubber raw materials under high temperature and pressure to plasticize and mix them evenly. Double-roll extrusion technology can provide a continuous processing process with high production efficiency and low cost.

[0003] The SBR rubber material preparation equipment mentioned in the existing Chinese public patent authorization announcement number: CN219838034U includes a rubber mixer body, a roller is arranged on the outer surface of the rubber mixer body, a protective plate is arranged on the outer surface of the rubber mixer body, a protective mechanism is arranged on the outer surface of the protective plate for protecting the rubber material when it is placed on the outer surface of the roller, the protective mechanism includes an auxiliary plate arranged on the outer surface of the protective plate, a threaded rod is arranged on the upper surface of the rubber mixer body, the protective plate is movably plugged into the outer surface of the threaded rod, a nut cap is threadedly connected to the outer surface of the threaded rod, and the position of the protective plate corresponds to the position of the roller. The SBR rubber material preparation equipment separates the user from the position between the two groups of rollers by arranging the protective plate and the roller, and does not affect the use of the rubber mixer.

[0004] In actual use, in order to make the rubber material more dense and uniform, and eliminate the bubbles and holes therein, it is often necessary to perform multiple overlapping and rolling. Through repeated overlapping and rolling, the rubber raw materials can be further mixed, plasticized and evenly distributed, thereby improving its heat resistance and anti-aging performance. However, the rolling method in the prior art is to manually guide the rubber material through two sets of rollers for rolling, which makes the rubber raw materials only undergo short-term compression and extension, and it is difficult to fully mix and plasticize, so that the bubbles and holes in the rubber raw materials are difficult to eliminate, resulting in its density and uniformity not meeting the standards, and reducing the heat resistance and anti-aging performance of the finished rubber material.
