[0029] Figure 5 As shown, the structure of the removing mechanism is shown, and the telescopic cylinder is also used, which is called a removing cylinder 12 in the removing mechanism. The removing cylinder 12 can be fixed on the bottom of the mounting plate 1 or the bag breaking mounting plate 4, and the removing cylinder 12 can be fixed or arranged through the bag breaking mounting plate 4. The bottom of the bag breaking mounting plate 4 is provided with a bottom plate 16 through a vertical column 15, and the vertical column 15 can also be an adjustable component, so that the distance between the bag pushing plate 11 below and the material bag is realized. The output shaft of the removing cylinder 12 is elongated, the bag pushing plate 11 is lowered, and the waste bag is removed. At this time, the pins 10 are in the vertical state.
