The fixing frame 1 is a frame structure, and vertical supports 11 are respectively provided on both sides thereof, and the vertical supports 11 are arranged vertically. The sliding frame 2 is slidably connected with the vertical supports 11 , and a sliding frame 2 is installed on each vertical support 11 . The sliding frame 2 and the vertical support 11 can be connected by sliding rails, so that they can slide up and down along the vertical support 11 .

The tray support 3 is used to support the material tray 6 , and two or more tray supports 3 are arranged on the vertical brackets 11 on each side, and the two or more tray supports 3 are arranged at intervals in the height direction of the vertical bracket 11 , It can be evenly distributed on the vertical support 11 . The tray supports 3 can be mounted on both sides of the vertical bracket 11 .

The tray supports 3 on the two vertical brackets 11 are arranged in pairs, and each pair of tray supports 3 is in the same plane for supporting the material tray 6 .

The tray support 3 is mounted on the vertical bracket 11 , which can be rotated on the vertical bracket 11 , so that the tray support 3 is pivotally mounted on the vertical bracket 11 .

The tray support 3 can be mounted on the vertical support 11 through a shaft, and it can rotate around the shaft or rotate together with the shaft, and these rotation modes can be set as required.

A first stop pin 111 is provided below each tray support 3 for preventing the tray support 3 from rotating downward. The tray support 3 has an initial position or a normal position. In the initial position, the tray support 3 is located on the first stop pin 111, and its end extends toward the vertical bracket 11 on the other side, so that it can support the two vertical brackets. Material tray 6 between 11.

The first stop pin 111 is fixedly installed on the vertical bracket 11, which is located below the tray support 3 and between the two ends of the tray support 3, so as to only allow the tray support 3 to rotate upwards from the initial position, but not. Turn down from the initial position.

Therefore, when the lower material tray 6 moves upward, the upper tray support 3 can be lifted up and rotated upward to avoid the material tray 6 so that the material tray 6 can move above the upper tray support 3 . After the material tray 6 is moved to the top of the upper tray support 3, after the tray support 3 is separated from the material tray 6, the tray support 3 can be automatically reset to the initial position under the action of its own weight, so as to support the movement to this position.
