Press roller structure for biomass granulator

Abstract

The invention discloses a press roller structure for a biomass granulator. The press roller structure comprises a press roller shell, and a press roller shaft arranged at the center of the press roller shell, the press roller structure is characterized in that a plug and an oil cup are respectively arranged at two ends of the press roller shaft, four bearings are arranged at the outer ring of the pressure roller, each two bearings are symmetrically fixed in a round nut, the round nut is fixed at the outside of the press roller shaft, a circlip for hole is arranged at the outside of the round nut, and the circlip for hole is connected with a press roller close cover; the press roller close cover is arranged at the connecting part of the press roller shell and the press roller shaft; by use of the 4-bearing structure, the press roller structure disclosed by the invention breaks through the traditional structure way, and greatly improves the service life of the press roller shell and the bearings; and the service life is more than three times of that of the traditional structure. The press roller shell is high in hardenability by use of the carburizing steel material; under the condition of guaranteeing the full hardening, the press roller structure has high low-temperature impact tenacity, and the service life is longer.

Description

technical field [0001] The invention relates to a pressure roller structure, in particular to a pressure roller structure for a biomass pellet machine, and belongs to the field of pellet machine technical equipment. Background technique [0002] The granulator press roller is the heart part of the granulator. When working, the ring die is rotated by the motor through the reducer, and the pressure roller installed in the ring die passes through the material between the die rollers and the friction between the ring die to make the pressure roller rotate without revolution. Due to the rotation of the die roller, the die , the material between the rollers is clamped and squeezed, and finally it is continuously extruded from the die hole in a columnar shape, and then cut into particles of a certain length by a fixed cutter installed outside the ring die; however, the pressure roller is a vulnerable part , The traditional pressure roller has only one bearing, which is easy to wea...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to overcome that the existing pressure roller structure is a vulnerable part. The traditional pressure roller has only one bearing, which is easy to wear and tear in practical applications, and the replacement cycle is frequent, which affects the user's use cost and is not conducive to exerting The defect of the efficiency of the pellet machine, provide a feeder rotary connection device, so as to solve the above problems
