Description

Technical Field

[0001] The utility model belongs to the technical field of material block screening, and more specifically, relates to a negative pressure type screening device for recycling material blocks of injection molding. Background Art

[0002] When recycling injection molding waste blocks, the blocks need to be spread flat on the conveyor belt first, and then the color of the blocks is determined by the color recognition system. When a multicolored block is identified, the system will send a signal to the negative pressure suction nozzle to suck away the multicolored block. The single-color block will be transported to the collection box by the conveyor belt, and then the injection molding waste will be re-granulated.
