The invention discloses an opening mechanism for toy production. The mechanism structurally comprises protective borders, an operation platform, a transportation platform, operation buttons and a supporting and fixing plate, and is characterized in that the side surface of the operation platform is attached to the outer surface of the corresponding protective border, the protective borders are arranged on two sides of the transportation platform, and the operation platform is connected with the transportation platform through the protective borders; a protective shell, a manual rotary pushingdevice, a shaking cutting extrusion wheel, a rotary conveying device, a power fan, a rotary transmission wheel, a storage and classification cell, a hydraulic cylinder and a pushing cutting rod are included; a rotary push conveying device is embedded and installed in the protective shell, the storage and classification cell is embedded and installed in the protective shell, and the hydraulic cylinder is installed above the storage and classification cell. The opening mechanism for toy production has the advantages that cotton in toys can be subjected to secondary cutting and becomes more delicate, can be fully classified and rolled by impact, and falls into the storage and classification cell more evenly.
