A bag blowing blower is provided next to the double-screw extrusion degassing device. It is designed for ton bags with inner linings and can realize the automatic bag blowing function. Two lifting cylinders are provided next to the bag blowing blower. The lower part of the cylinder is connected to the ton bag lifting frame, which can cope with the packaging of ton bags of multiple sizes. A vibrating air hammer is provided below the ton bag lifting frame. The vibrating air hammer is installed next to the discharge pipe. After the discharge is completed, the vibrating air hammer will automatically vibrate the pipe mouth to ensure that all the residual materials in the discharge pipe enter the ton bag. A bag-clamping airbag is installed beneath the vibrating hammer. Once inflated, the airbag automatically expands and clamps the bag opening, saving time and improving efficiency. A weighing platform and automatic bag discharge roller conveyor are located beneath the ton bag. When the bag weight reaches the set value, loading stops automatically, the roller conveyor starts, and the bag is automatically discharged, facilitating the transfer of ton bags.
