Granulating device for polyurethane film production

Abstract

The invention discloses a granulating device for polyurethane film production, and relates to the technical field of polyurethane film production. The granulating device for the polyurethane film production comprises a box body, a feeding mechanism is arranged at the top of the box body, an extrusion mechanism is arranged at the top of the inner side of the box body, and supporting plates are fixedly installed on the inner walls of the two sides of the box body. According to the granulating device for the polyurethane film production provided by the invention, through cooperative use of a first motor, a rotating column, a first gear, a second gear, a driving wheel, a fixed transverse plate, a feeding box, a stirring column, a spiral blade, a driven wheel, a transmission belt and a feedingpipe, through spiral feeding of the feeding box, repeated manual addition of polyurethane film raw materials is avoided, the labor amount of workers is reduced, and the feeding work becomes safer, time and labor are saved, the working efficiency is improved, and the situation that the extrusion work cannot be carried out due to the fact that too many polyurethane film raw materials are stored in an extrusion box is also avoided.

Description

technical field [0001] The invention relates to the technical field of polyurethane film production, in particular to a granulation device for polyurethane film production. Background technique [0002] In the production of polyurethane film, after the ingredients are mixed, the mixed material needs to be made into granules, which is convenient for material handling. At the same time, the granulated material is convenient for the film blowing process in the later stage, so it is necessary to use a granulator to make the mixed material into granules shape. [0003] On the one hand, some existing granulation devices are easy to block the granulation area during the granulation process, thus reducing the use time of the device; on the other hand, the granulation speed is slow, and there is no screening in the granulation process The function needs to be screened after the granulation is completed, and the operation steps are complicated, which reduces the work efficiency.
