Adjustable cutting and granulating die and roller granulator

Abstract

The invention provides an adjustable cutting and granulating die and a counter-roll granulator. The adjustable material cutting and granulating die includes: a die roller, a plurality of feeding holes are arranged in the circumferential direction of the outer wall, a feeding hopper is arranged inside, the die roller can rotate around the feeding hopper; a feeding rod is installed at the opening of the feeding hopper, and It is spaced from the outer wall of the die roll, and the material-breaking rod is arranged parallel to the axial direction of the die-roller; the material-cutting control mechanism is assembled in the hopper and connected with the material-breaking rod. The material-cutting control mechanism can adjust the distance between the material-breaking rod and the die roll. spacing of inner walls. It can be seen that the adjustable material cutting and granulating mold can flexibly adjust the distance between the material cutting rod and the inner wall of the mold roll through the material cutting control mechanism, so as to flexibly adjust the length of the discharged particles, and the operation process is simple and reliable, and the mold roll can be stopped. The online adjustment of the position of the material breaking rod can be realized at the bottom, so as to ensure the high working efficiency of the pellet machine.

Description

technical field [0001] The invention relates to the technical field of pellet mills, in particular to an adjustable material cutting and pelletizing die and a counter-roll pellet mill. Background technique [0002] At present, the structure of granulator at home and abroad is mainly divided into two types: ring die granulator and double roll granulator. The ring die pellet machine appeared early, with a long development period, and the mechanical structure and functional layout tended to be stable. The material is discharged from the outside of the die and the particles are cut off by an external rotating metal blade, and the length of the cut material can be adjusted by adjusting the radial position of the blade. In the double-roller pellet mill, when the length of the discharged pellets needs to be adjusted, the whole machine and the double-roller must be disassembled and then disassembled to the state of the parts before replacement. . SUMMARY OF THE INVENTION [000...

AI Technical Summary

Problems solved by technology

[0003] The invention provides an adjustable material cutting and granulation mold, which is used to solve the problem that when the existing double-roll granulator needs to adjust the length of the discharged particles, the whole machine and the double-roll must be dismantled and continued to be disassembled to the state of parts before they can be replaced. Low efficiency, heavy workload, and it is not convenient for the defect of verification work after replacement
