On May 17, 2026, information from the State Intellectual Property Office showed that a patent called “a rubber pretreatment mechanism” applied by Shandong Linglong Tire Co., Ltd. was authorized.
The authorization announcement number is CN224240295U, and the authorization announcement date is May 15, 2026.
The application number of this patent is CN202520836712.0, the application publication date is May 15, 2026, and the application date is April 28, 2025.
This patent involves rubber pretreatment technology, which is of great significance.
The patent abstract shows that the rubber pretreatment mechanism disclosed in the utility model includes a box body. The top and bottom ends of the box body are open-shaped. A first crushing roller and a second crushing roller are rotatably connected inside the box body, and the two are parallel to each other.
A motor is provided on one side of the box, and the output end of the motor is connected to one end of the first crushing roller. A driving gear and a driven gear are rotatably connected to the other side of the box, and the driving gear and the driven gear mesh with each other.
By driving the motor, the first crushing roller will rotate in the direction of the second crushing roller, and at the same time drive the driving gear to rotate. The driving gear meshes with the driven gear, causing the driven gear to rotate in the opposite direction to the driving gear, so that the second crushing roller rotates in the direction of the first crushing roller, thereby crushing the whole piece of rubber material, reducing the volume of the rubber material, reducing the workload of the screw inside the extruder, and conducive to long-term production and processing.
