Along with the strict implementation of domestic environmental protection laws and regulations, the cleaning cost of the ton barrel is improved, and more ton barrels can be additionally provided with lining bags when in use, so that the cleaning cost is reduced. The ton bucket lining bag that circulates in the existing market is mostly only applicable to and adorns promptly, just can guarantee that lining bag and bucket wall laminate completely. If the lining bags are prepared in advance, the lining bags are usually collapsed in the container when the container is transported to a loading site, and the lining bags cannot be well attached to the corresponding container walls on all sides, so that the filling is affected. The reason is that the material inlet and outlet are connected with the lining bag and are not sealed, so that vacuum air leakage between the lining bag and the barrel wall is easily caused; in addition, some viscous liquid materials have poor liquidity, so that the viscous liquid materials cannot flow out by free flow at the end of discharging, and partial lining bags need to be pulled out from a discharging port manually for auxiliary material extrusion.
