The utility model discloses a thermoplastic polyurethane elastomer pelletizing and noise reducing device, relates to the related field of polyurethane processing devices, and aims to solve the problems that noise is generated after an existing pelletizing device is in contact with a polyurethane elastomer, clattering fragile sound is accompanied in the blanking process, environmental protection is not facilitated when the noise is too large, and the service life of the pelletizing device is prolonged. And meanwhile, the working comfort of constructors is reduced. The device comprises a base, an operation table is fixedly connected to the top of the base, the shape of the operation table is trapezoid, first noise reduction cotton is fixedly connected to the two sides of the operation table, discharging openings are formed in the two sides of the interior of the base, a material collecting box is fixedly connected to the bottoms of the discharging openings, and hinges are arranged at the edge of the inner botto
