Ultra-precision thermoplastic composite material granulator

Abstract

The invention discloses an ultra-precision thermoplastic composite material granulator. The ultra-precision thermoplastic composite material granulator comprises a rack and a granulating device arranged on the rack, the granulating device comprises a bottom plate, a housing, a rotary knife roll, an upper press roll and a lower press roll, the bottom plate is fixed on the rack, the housing is arranged on the bottom plate, and the rotary knife roll, the upper press roll and the lower press roll are all arranged in the housing. The upper press roller and the lower press roller are both located on one side of the rotary knife roller and are distributed up and down, a knife holder is further arranged between the rotary knife roller and the lower press roller, a fixed knife is arranged on the knife holder and is of a cuboid structure, and two faces of the fixed knife are concave towards the center. A gap between one concave face of the fixed knife and the outer wall of the rotary knife roller is a discharging gap, a discharging barrel is further arranged at the bottom of the bottom plate, and the discharging barrel extends out of the rack.

Description

Technical field: [0001] The invention belongs to the technical field of pelletizers, in particular to an ultra-precision thermoplastic composite material pelletizer. Background technique: [0002] Thermoplastic composite materials need to be pelletized during the processing process. The pelletizer is the main equipment used for pelletizing processing. The existing pelletizer still has the material that is easy to follow the rotary knife roller when pelletizing the filament composite material. There are many defects such as secondary cutting due to rising, equipment accidents due to thermal expansion, and poor cutting accuracy of materials. [0003] The information disclosed in this Background section is only intended to increase the understanding of the general background of the present invention, and should not be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those of ordinary skill in the art. ...
