Problems solved by technology

The diameter of the screw in the existing plastic granulator is consistent from the beginning to the end, but the depth of the thread and the pitch of the thread are very limited to change the volume of the screw groove, and the help to the rapid accumulation of extrusion force is also very limited. , which is of little help to increase the production capacity of the plastic granulator

Abstract

The invention discloses an incompletely plasticized plastic granulator which comprises a stand, a power device, a feeding device, a heating device, an extruding device, a dicing device and a discharging device, wherein the feeding device comprises a first thread sleeve section and a front part of a screw rod; and the extruding device comprises a second nut sleeve section, a third nut sleeve section and a middle-rear part of the screw rod. The plastic granulator disclosed by the invention has a reasonable structure; a granulating method is novel; the purposes of low energy consumption and high throughput can be realized in the whole production process; in addition, the quality and the value of the product can be well guaranteed; and the invention has favorable application value and market value.

Description

technical field [0001] The invention relates to a granulator and a production method thereof, in particular to an incompletely plasticized plastic granulator and a granulation method thereof. Background technique [0002] The plastic granulator is an automatic molding machine used to process waste plastic films into granular recycled plastics, which is suitable for most common waste plastics. Existing plastic granulators generally use the technology of complete plasticization to achieve the purpose of granulation. Therefore, the plastic granulator needs to provide a temperature higher than the melting point of the plastic to melt the plastic, resulting in more power consumption for heating the plastic. The current complete plasticization technology is to heat and melt the plastic and then crystallize and granulate. In this process, not only the shape of the plastic is changed, but also the molecular structure inside the plastic is also changed, that is, the plastic is comple...
