TECHNICAL FIELD

[0001] The application relates to the field of dicing equipment, in particular to a nanometer plastic dicing device with a self-cleaning scraper. BACKGROUND

[0002] The granulation method of nanometer plastics includes the steps of preparation, extrusion into strips, cooling, dicing and the like. The nanometer plastic dicing device is mainly used for processing the cooled nanometer plastic strips into nanometer plastic particles. The dicing blade on the cutting roller reciprocally cuts and continuously moves towards the nanometer plastic strips on the cutting roller by driving the cutting roller to rotate.

[0003] In the related art, during the cutting of the nanometer plastic strips, nanometer plastic residues will stick to the dicing blade. If the nanometer plastic residues on the dicing blade are not cleaned in time, the dicing blade will be more prone to sticking to nanometer plastics, resulting in an increasing number of nanometer plastic residues, which affects the dicing process.

[0004] Therefore, it is urgent to provide a nanometer plastic dicing device with a self-cleaning scraper to disperse multiple nanometer plastic strips. CONTENT OF THE INVENTION

[0025] The main shaft 1, the cutting roller 2 and the cutting blade 5 on the cutting roller 2 constitute a cutting structure, and the main shaft 1 rotates under the drive of an external force, thereby driving the cutting blade 5 to cut the nanometer plastic strip. The installation plate 3 is the installation basis of the scraper 15 and the elastic member 13, and the installation plate 3 and the cutting blade 5 are installed on the installation surface 9 of the cutting roller 2 through installation screws 4. The scraper 15 and the elastic member 13 constitute the core structure of the nanometer plastic cutting device with the self-cleaning scraper 15.
