Abstract

The invention relates to the technical field of wood machining rotary cutting equipment, in particular to a small-diameter log four-roller automatic material supporting and rotary cutting mechanism for thick veneer machining. The small-diameter log four-roller automatic material supporting and rotary cutting mechanism for thick veneer machining is characterized in that the small-diameter log four-roller automatic material supporting and rotary cutting mechanism for thick veneer machining increases the friction force of rollers on a small-diameter log through the four rollers when a rotary cutting machine is used for rotary cutting of a thick veneer. According to the four-roller automatic material supporting and rotary cutting mechanism for small-diameter log and thick veneer machining, thethick veneer is obtained through rotary cutting of a rotary cutter, and the effect of automatic material supporting before rotary cutting of the small-diameter log can be achieved through a set of extrusion roller wheels, a V-shaped frame, an upper pressing roller and a cam mechanism, so that the structure is more compact, and the requirement of actual production is more advantageously met.

Description

technical field [0001] The patent of the invention relates to the technical field of wood processing rotary cutting equipment, and is a four-roller automatic supporting rotary cutting mechanism for processing small-diameter thick veneers. Background technique [0002] The rotary cutting mechanism of the existing cardless rotary cutting machine has only three rollers, which are distributed in a triangular structure. Arranged vertically up and down, the center of the pinch roller is above the vertical bisector of the center of the driving double roller, the friction force provided to the small diameter material is limited during rotary cutting, and it cannot cut thick veneer. [0003] The invention uses four rollers to fix the small-diameter material at the center of the four rollers, increases the friction of the rollers on the small-diameter material to meet the requirements of processing thick veneer, and uses a group of extrusion rollers, V-shaped frames and cams to The m...
