As Figure 1 and Figure 2As shown, the material clamping unit 5 is arranged above the material suction unit 2, and the material clamping unit 5 corresponds to the clamping of the bag opening part. The material clamping unit 5 is in transmission connection with the clamping power source. The material clamping unit 5 includes oppositely arranged front clamping plates and rear clamping plates. The front clamping plate and the rear clamping plate have a clamping cavity for clamping the bag opening part. The front clamping plate and the rear clamping plate of the material clamping unit 5 adopt front-to-rear relative translation type clamping, or adopt relative swing type clamping. The front-to-rear relative translation type clamping can be that the piston rods of the double-acting cylinders are respectively connected with the front clamping plate and the rear clamping plate, so that the front clamping plate and the rear clamping plate are relatively linearly moved, thereby opening or closing the clamping cavity to realize clamping and releasing, and the clamping structure is simple. The relative swing type clamping includes a rotary driving unit (such as a rotary cylinder or a servo motor), which drives the front clamping plate and / or the rear clamping plate to relatively rotate around the connecting shaft for clamping.

[0028] In addition, the suction unit 2 generally takes the material through the suction of one side of the material, and the bag opening is prone to be opened, so that the stroke of the clamping unit 5 is too large, and space is wasted. In order to ensure that the initial state of the bag opening is closed, and facilitate clamping, the material blocking piece 7 is arranged on the upper part of the discharge port of the vertical silo 1, and the material blocking piece 7 is arranged on the side plate of the vertical silo 1 through the left and right adjustment of the guide groove.
