[0002] Before the present invention, the heat grinding section (fiber separation section) on the medium-density wood-based panel production line adjusts the grinding disc clearance of the main machine of the thermal grinding machine by manually adjusting the worm gear. Although the labor intensity has been reduced and the production efficiency has been improved, the structure of the mechanical contact of the worm gear and the worm cannot avoid the instantaneous impact force during the gap adjustment process is still very large. Active, flexible hydraulic tensioning device for gentle adjustment without impact

Abstract

The invention relates to a hot grinding machine technique in medium-density artificial board production line, specially a hydraulic tension apparatus technique in gas adjusting mechanism of spindle millstones of hot grinding machine, the gas between tension rod and hydraulic cylinder is linked with that of the spindle millstones, where the hydraulic cylinder is composed of belt exhaust-pressure testing joint, O rings, box body, oil inlet and so on, with the assurance of the oil way of the safe and reliable hydraulic tension apparatus, the pressure variation of pressure oil of oil way system in the hydraulic cylinder makes the gas variation course of the spindle millstones become soft, not producing impact phenomenon.

Description

technical field [0001] The invention relates to a heat refiner equipment on a medium-density wood-based board production line, in particular to a hydraulic tensioning device in the gap adjustment mechanism of the main grinding disc of the heat refiner. technical background [0002] Before the present invention, the heat grinding section (fiber separation section) on the medium-density wood-based panel production line adjusts the grinding disc clearance of the main machine of the thermal grinding machine by manually adjusting the worm gear. Although the labor intensity has been reduced and the production efficiency has been improved, the structure of the mechanical contact of the worm gear and the worm cannot avoid the instantaneous impact force during the gap adjustment process is still very large. Active, flexible hydraulic tensioning device for gentle adjustment without impact. Contents of the invention [0003] The technical solution of the present invention is to bold...
