The end surface of the plug block 2 perpendicular to its extending direction is fixedly connected to the edge of the side surface of the conversion disk 1, so that the conversion disk 1 drives the plug block 2 to pass through the inlets of the two feeding channels 72. In a specific embodiment, as Figure 1As shown, the conversion disk 1 is parallel to the YZ plane, and the extending direction of the blocking block 2 is the X direction; the size of the first side surface of the blocking block 2 matches the sizes at the entrances of the two feeding channels 72, so that when the blocking block 2 is located at the entrance of one of the feeding channels 72 during operation, the material is conveyed from the incoming material channel 71 to the other feeding channel 72. In a preferred embodiment, the blocking block 2 is surrounded by a first side surface, a second side surface, and two end surfaces. The first side surface is an arc surface, the second side surface is a flat surface, the cross-section of the blocking block 2 perpendicular to its extending direction is in a bow shape, the size of the second side surface in the direction perpendicular to its extending direction is greater than or equal to the size of the feeding channel 72 entrance in the direction perpendicular to the extending direction of the second side surface, and the center of the cross-section of the blocking block 2 and the rotation center of the conversion disk 1 are on the same straight line, that is, the straight line extending along the x direction and passing through the rotation center.
