Multiple cutting blades 512 are provided, and the clamping discs 513 of adjacent cutting blades 512 are separated by a spacer 515. Specifically, one or more cutting blades 512 can be installed on the cutting spindle 5031. In this embodiment, there are three cutting blades 512, and the distance between the cutting blades 512 is adjusted by multiple spacers 515. By tightening the expansion sleeve screw 5142, the expansion sleeve 5141 is made to hug and clamp the cutting spindle 5031 inwards, while simultaneously expanding and tightening the movable part outwards. The movable sleeve 5143 is axially positioned on the cutting spindle 5031, and this positioning is random. The two sides of the cutting blade 512 are clamped between the clamping discs 513. The outer side of the clamping disc 513 at the end contacts the corresponding movable sleeve 5143. By tightening the movable sleeve screw 5144, the movable sleeve 5143 is pressed against the clamping disc 513, so that all discs, sleeves and pieces between the two movable sleeves 5143 are in a clamped state. The static friction generated by the clamping makes the cutting blade 512 rotate with the cutting spindle 5031, thereby realizing the automatic cutting of the bottom of the ton bag.

The second slide groove is fixed to the rear side of the housing 1 and extends in the left-right direction. The second rack is slidably connected in the second slide groove. One end of the second crank is hinged to the right side of the rear side of the housing cover 2, and the other end is hinged to the middle of the rear side of the housing 1 and meshes with the second rack. One end of the second rocker arm is hinged to the left side of the rear side of the housing cover 2, and the other end is hinged to the left side of the rear side of the housing 1. The cylinder rod of the second cover opening / closing cylinder extends in the left-right direction and is connected to the second rack.

[0056] The first opening and closing cylinder 705 can drive the first rack 702 to slide along the first slide groove 701, and the second opening and closing cylinder can drive the second rack to slide along the second slide groove to open or close the box cover 2. In use, the opening and closing action of the box body 1 is completed by the front gear rocker arm assembly 7 and the rear gear rocker arm assembly 8. After the ton bag is hoisted into the box body 1, the box cover 2 is covered by the action of the first opening and closing cylinder 705 and the second opening and closing cylinder. An airbag sealing strip 201 is also provided at the lower opening of the box cover 2, which forms a sealed state when the cover is closed.

[0057] Furthermore, in this embodiment, a hanging ear 105 is also provided on the upper part of the box 1. When the ton bag is hoisted into the box 1, the sling of the ton bag is fastened to the hanging ear 105 so that the ton bag is always kept in the upper part of the box 1 and does not fall down.

[0058] In this embodiment, as Figure 8 As shown, the unpacking machine also includes a pushing mechanism, which includes a pushing frame 9, pushing rods 901, pushing inclined plates 902, and pushing cylinders 10. The pushing frame 9 is a square frame, horizontally arranged inside the housing 1 and below the support frame 3. Multiple pushing rods 901 are arranged in the middle of the pushing frame 9, and multiple pushing inclined plates 902 are arranged around the perimeter of the pushing frame 9. The cylinder rods of the pushing cylinders 10 are vertically upward, and four pushing cylinders 10 are provided. The cylinder rods of the four pushing cylinders 10 are respectively connected to the four right angles of the pushing frame 9, so that the pushing frame 9 can move up and down, thereby moving the pushing rods 901 and pushing... The top inclined plate 902 compresses the ton bag on the support frame 3. During use, the four top-pushing cylinders 10 work simultaneously to move the top-pushing frame 9 up and down. At the same time, the top-pushing rod 901 pierces the ton bag from the middle and squeezes the powder, enhancing the flow of the powder. The inclined surface of the top-pushing plate 902 compresses the ton bag, giving the powder inside the bag the function of being pushed by external force. This results in the ton bag having a relaxation and self-weight compression effect, promoting the sliding of the powder inside the bag. It should be noted that inside the housing 1, the top-pushing rod 901 and the top-pushing inclined plate 902 avoid the support frame 3 and are located in the empty space inside the support frame 3, so they can move up and down.
