The invention provides a brush with independent bristles and a manufacture device thereof. In a graph of the specification from the top to the bottom, (1) each brush bristle is put in a concave pedestal by a bristle screening device, a glue A and a glue B are injected to wait for glue solidification; (2) the bristle screening device screens each brush bristle into a pedestal filled with a normal temperature plastic, the brush bristle is knocked into the plastic by a ram, and the plastic is solidified; (3) the brush bristles are put into a channel by a cross bristle feed device and a cooling wall, jet flow drives a jet hammer to make the brush bristles to be jetted into a pedestal filled with a thermoplastic through a porous template (mesh); (4) the jet flow jets the brush bristles into the pedestal filled with a thermoplastic; (5) the jet flow jets the brush bristles into the pedestal filled with a thermoplastic through a thick porous template; and (6) the jet flow jets the brush bristles into the pedestal filled with a thermoplastic through a multi-pin jet hammer, and bristle implanting is completed after the thermoplastic is cooled.
