On June 3, information from the State Intellectual Property Office showed that a patent filed by Guizhou Tire Co., Ltd. titled “An automatic rubber extruder pin extraction device” was authorized.
The authorization announcement number is CN224296515U, the authorization announcement date is May 29, 2026, the application number is CN202521216091.2, and the application date is June 13, 2025.
The patent summary shows that this utility model relates to the technical field of rubber extruders.
The device includes a motor reducer, a rotating mechanism, a moving mechanism and a pin extraction tool.
The motor reducer is used to drive the rotating mechanism to rotate. The moving mechanism is transmission connected with the rotating mechanism. The pin extraction tool is installed at the end of the moving mechanism, and the end is equipped with a bolt structure that matches the internal thread of the pin body. There is a one-way anti-rotation cover on the outside. The two cooperate to achieve one-way rotation.
By arranging the above structure, during the entire pin extraction process, the operator only needs to press the start button to remove the pin, which greatly improves the work efficiency and reduces the labor intensity of the operator.
