The base 31 is fixedly arranged in the blanking space 11, the support frame 32 is slidably mounted on the base 31, at least one bearing position 321 for bearing materials is arranged on the support frame 32, a linear driver for driving the support frame 32 to move is arranged on the base 31, and the linear driver can be realized by a cylinder, a hydraulic cylinder, an electric cylinder or a motor matching transmission mechanism.

During the manual blanking operation, the worker places the material on the loading position 321, closes the cover structure 12, and connects the isolation device 20, at which time the support frame 32 moves toward the automated production or conveying area under the action of the linear driver, so that the conveying equipment (automatic gripping or lifting mechanism) in the automated production or conveying area takes away the material. Preferably, the conveying mechanism 30 further comprises a secondary slide table 33, the secondary slide table 33 being mounted on the base 31 and being slidable between a position close to the isolation device 20 and a position close to the cover structure 12, and the support frame 32 being mounted on the secondary slide table 33 and being slidable between a feeding position and a blanking position.

In the blanking position, the bearing position 321 of the supporting frame 32 is within the projection range of the vertical direction of the secondary sliding table 33, so that the bearing position 321 is close to the cover structure 12, and the blanking operation is convenient. In the feeding position, the bearing position 321 of the support frame 32 extends out of the projection range of the vertical direction of the secondary sliding table 33.
