Technical Field

[0001] This utility model relates to the technical field of raw rubber processing equipment, and more specifically, it relates to a raw rubber plasticizing machine. Background Technology

[0002] Rubber has a wide range of applications in our daily lives. During the processing of rubber, it needs to be plasticized. Plasticization refers to the process of changing the properties of raw materials through mechanical crushing, thereby improving the plasticity, flowability and adhesion of the rubber compound. When plasticizing raw rubber, the raw rubber blocks need to be shredded first so that the rubber blocks are put into production and processing in appropriate size particles.

[0003] A search revealed that Chinese utility model patent application number CN202222276884.6 discloses a raw rubber plasticizing machine, which includes a crushing box shell, a feeding hopper, an electric crushing blade, a filter mesh plate, and a first discharge port. The first discharge port is located on the side of the crushing box shell, the feeding hopper is located on the surface of the crushing box shell, and the electric crushing blade is installed inside the crushing box shell. The raw rubber plasticizing machine also includes an elastic support assembly located inside the crushing box shell, with an installation frame connected to the outside of the elastic support assembly, and the filter mesh plate is installed inside the installation frame.

[0004] When in use, the rubber particles screened from the filter mesh plate fall onto the guide plate. Because the rubber particles are irregularly shaped, they are not easy to roll on the guide plate, and the rubber particles tend to accumulate on the guide plate. In addition, it is not easy to discharge larger rubber particles during the screening process, and it is not easy to further crush the screened rubber particles. Utility Model Content

The multiple shifting plates 7 move the rubber particles on the guide plate 4. During the movement of the rubber particles, they slide down on the guide plate 4, which can prevent the rubber particles from accumulating on the guide plate 4 and increase the sliding speed of the rubber particles on the guide plate 4.

[0024] Please see Figure 1 and Figure 2 A cover 16 is fixedly connected to the top of the crushing box shell 1. A feeding pipe 17 is fixedly connected to the top of the cover 16 at the position corresponding to the middle of the two electric crushing blades 2, which facilitates the addition of rubber raw materials into the crushing box shell 1. A first collection box 18 is placed below the filter mesh plate 3. An auger 19 is fixedly connected inside the first collection box 18. The discharge pipe of the auger 19 extends to the upper side of the feeding pipe 17, which facilitates the conveying of large rubber particles inside the first collection box 18 to the middle of the two electric crushing blades 2.

[0025] Specifically, large rubber particles on the filter mesh plate 3 slide into the interior of the first collection box 18.
