The lifting plate at the top of the piston rod is respectively provided with a suction cup for sucking the bottom of the outer woven bag of the ton bag and an annular hot-melt cutter for forming an annular incision at the bottom of the outer woven bag of the ton bag. The annular hot-melt cutter is located at the periphery of the suction cup. The present invention can realize the automated operation of powder unpacking, prevent site pollution, improve the efficiency of ton bag unloading, protect the health of site personnel, and solve the problem that harmful powder will escape or be taken out of the cage when workers are unloading, thereby causing site and air pollution and seriously affecting the health of site personnel. In addition, manual unloading also has the problem of low operating efficiency.

[0004] In daily work, it is found that when unpacking the inner bag of a ton bag, the inner bag unpacking device of the existing powder unpacking machine mostly contacts the inner bag with a cone, thereby piercing the bottom of the inner bag. However, the cone can only pierce a certain size of the bottom of the inner bag. When unloading, the powder and the cone contact and accumulate and become blocked, resulting in poor fluidity of the overall powder, affecting unloading. This leads to the problem that the inner bag unpacking device of the existing powder unpacking machine has poor unpacking effect and affects unloading. Utility Model Content
