Problems solved by technology

[0003] The existing granulation device extrudes the melted raw material through the spiral blade to multiple outlets, and then it is scraped off by the scraper to form a plurality of masterbatch particles. Since the particles are extruded by heat, after that Because the particles are not completely cooled, they are easy to stick together, resulting in poor granulation quality. The existing technology uses wind to cool down, the effect is not obvious enough, and the cooling speed is slow.

Abstract

The invention discloses a thermoplastic polyurethane masterbatch granulating device. The thermoplastic polyurethane masterbatch granulating device comprises an extrusion container and a helical blade,wherein the helical blade is transversely rotationally installed in the extrusion container, the helical blade is in transmission connection with a second driving motor fixed to the right side of theextrusion container, a cooling room is arranged on the left side of the extrusion container, three filter nets are obliquely fixedly welded to the bottom of the cooling room, copper pipes are fixed to the bottoms of the filter nets, and the copper pipes on the bottoms of the three filter nets are communicated with one another. A plurality of extrusion holes are formed in the left surface of the extrusion container. By arranging the three filter net on the bottom of the cooling room and fixing the copper pipes to the bottoms of the filter nets, circulating cooling water can be introduced intothe copper pipes during granulating work, after being well manufactured, granulates enter the cooling room and then can be quickly cooled by the filter nets with the cooperation of the cooling water in the copper pipes, and the off-specification quality caused when the granulates are stuck together is prevented.

Description

technical field [0001] The invention relates to the technical field of polyurethane masterbatch granulation, in particular to a granulation device for thermoplastic polyurethane masterbatch. Background technique [0002] At present, thermoplastic polyurethane elastomer (TPU) has good tear resistance, wear resistance and low temperature flexibility, and is being used in more and more fields and products, such as shoe materials, mobile phone cases, wires and cables, films, Conveyor belts, etc., thermoplastic polyurethane is manufactured into finished products through its masterbatch particles, so its raw materials need to be granulated through a granulation device for subsequent processing operations. [0003] The existing granulation device extrudes the melted raw material through the screw blade to multiple outlets, and then scrapes it off by the scraper to form a plurality of masterbatch particles. Since the particles are extruded by heat, after that Because the particles ...
