Excess material ejection device

The utility model belongs to the technical field of production equipment, and discloses an excess material ejection device which comprises a bracket, a positioning plate arranged on the bracket, a plurality of ejection columns and a linear moving mechanism for driving all the ejection columns to do linear motion, a plurality of through holes are formed in the positioning plate, a jacking column is arranged in each through hole, and the jacking columns do linear motion in the corresponding through holes under the action of the linear moving mechanism; and a first air path is arranged on each top column and is communicated with the air suction interface. The fixture is placed on the positioning plate, the ejection column sucks air to suck a product on the fixture, when the suction nozzle sucks the product, the ejection column breaks air to loosen the product, meanwhile, the linear moving mechanism drives the ejection column to move towards the side of the fixture to eject the product, the suction nozzle reliabl
