The vacuum pump 3 is used to evacuate the interior of the vacuum storage tank 1. When the vacuum is evacuated, the suction pipe 7 will generate a large suction force, and the suction head 8 will generate a large suction force. At this time, the material can be drawn into the top box 5. At this time, the material is sifted out from the middle of the screen 602, and other debris in the material will be sifted by the screen 602. The material will enter the vacuum storage tank 1. When the material in the vacuum storage tank 1 is stored to an appropriate amount, the electric valve 2 will be opened, and the material stored in the vacuum storage tank 1 will fall into the printing device for loading. When the screen 602 is screening, the output end of the hydraulic cylinder 601 will be extended and retracted, which will drive the mounting ring 603 to move back and forth, and the screen 602 will be driven to move up and down, so that the screen 602 can shake, and the material on the screen 602 can shake, thereby speeding up the material screening efficiency. When the screen 602 needs to be replaced, the top box 5 is removed from the upper end of the vacuum storage tank 1, and the staff rotates the rotating column 610, so that the screen 602 can be rotated. And because a number of positioning rods 604 are fixedly installed at equal distances on the four sides of the output end of the hydraulic cylinder 601, a mounting ring 603 is fixedly installed on the top of the positioning rod 604, a screen 602 is installed at the lower end of the mounting ring 603, a rotating column 610 is fixedly installed on the lower surface of the screen 602, a limiting groove 605 is provided on the lower surface of the mounting ring 603, an internal thread 606 is provided on the inner wall of the limiting groove 605, a positioning ring 607 is fixedly installed on the side of the screen 602, and a limiting ring is fixedly installed on the upper surface of the positioning ring 607 608, the limiting ring 608 is arranged inside the limiting groove 605, and the side of the limiting ring 608 is provided with an external thread 609, and the external thread 609 is meshedly connected with the internal thread 606, so that the external thread 609 can be disconnected from the internal thread 606, and the limiting ring 608 can be detached from the limiting groove 605.
