[0002] At present, during the unloading process of the large-package powder ton bags in China, a large amount of dust will be generated, which will cause a bad environment in the workplace, affect the breathing of the staff, and seriously affect the health of the staff. The entire workplace and related instruments and equipment are covered with dust, which requires a certain amount of manpower to clean up. The cleaning labor of workers is heavy, and the labor intensity increases, which affects work efficiency and affects the economic benefits of enterprises.

[0003] The traditional bag unloading and unloading device consists of a clapper device, a pneumatic actuator, a main frame, and a bag unpacking device. When the big bag is hoisted above the main frame of the big bag, the bottom outlet of the big bag is placed in the unbagging device, which needs to be untied manually. Bag mouth, auxiliary blanking, cumbersome operation process, low degree of automation, affecting the efficiency of unpacking and blanking
