小径级圆木对中夹紧传动方法及装置

Small-diameter round log centering and clamping transmission method and device

Abstract

本技术提供一种适于小径级圆木纵向加工时使用的、能够对圆木在进给的同时对中夹紧、提高小径级木材出材率的小径级圆木对中夹紧传动装置和传动方法。该传动装置,包括带动圆木沿轴向移动的轴向驱动机构和至少三对对中辊;至少两对对中辊是上小下大的正圆锥形,至少一对对中辊是上大下小的倒圆锥形;每对对中辊中的两个对中辊对称分布在圆木的两侧;各对中辊转动设置在枢轴上;在工作台与枢轴之间设置有使得枢轴向圆木移动而把圆木夹紧在每对对中辊之间的枢轴驱动机构。该传动方法是,轴向驱动机构带动圆木沿轴向移动的同时,通过至少两对正圆锥形对中辊和至少一对倒圆锥形对中辊沿圆木径向对圆木进行对中夹紧。
The invention provides a small-diameter round log centering and clamping transmission method and device which are used when small-diameter round logs are longitudinally machined, can center and clamp the round logs while feeding the round logs, and can improve the percentage of outturn of the small-diameter round logs. The transmission device comprises an axial drive mechanism and at least three pairs of centering rollers, wherein the axial drive mechanism drives the round logs to move in the axial direction; at least two pairs of centering rollers are in a big-end-down conical shape; at least one pair of centering rollers is in a big-end-up inverted conical shape; the two centering rollers of each pair are symmetrically distributed on the two sides of the round logs; the centering rollers are arranged on a pivot in a rotary mode; a pivot drive mechanism is arranged between a workbench and the pivot and enables the pivot to move towards the round logs and clamp the round logs between each pair of centering rollers. According to the transmission method, the axial drive mechanism drives the round logs to move in the axial direction, and at the same time, the round logs are centered and clamped in the axial direction of the round logs through at least two pairs of conical centering rollers and at least one pair of inverted conical centering rollers.
