Description

Technical Field

[0001] The utility model relates to the technical field of foaming polymer material processing, in particular to a granulating device which can prevent material from being stuck in a feeding cavity. Background Art

[0002] Before most polymers can be made into final products, they must be compounded and then pelletized into marketable raw materials. The power required by a pelletizer is directly proportional to the extrusion rate and exponentially related to the filter size. While there are many different pelletizer designs, all can be divided into two categories: cold pelletizers and die-face hot pelletizers. The primary difference between these two types lies in the timing of the pelletizing process. Cold pelletizers pelletize from the solidified polymer at the end of the process, while die-face hot pelletizers pelletize the molten polymer as it emerges from the die.

[0003] At present, when processing and developing foaming polymer materials on the market, it is necessary to screen, mix and granulate the foaming polymer materials. In the actual processing and development of foaming polymer materials, especially when granulating the foaming polymer materials, a granulator is needed to granulate the foaming polymer materials. At this time, the foaming polymer material needs to be placed in the feed hopper on the granulator, and then transmitted through the feed screw at the bottom of the subsequent feed hopper. Because most of the foaming polymer material inside the feed hopper naturally enters the feed screw through gravity for transmission, sometimes the feed cavity between the feed hopper and the feed screw inside the feed hopper will get stuck.
