Numerical control card-less rotary cutter

Abstract

The invention discloses a numerical control card-less rotary cutter, which comprises a base, a front tool post, a rear tool post, a moving motor, compression rollers, a compression roller speed control system and a compression roller rotating motor, wherein two ends of the base are provided with upright brackets which are provided with round timber clamping mechanisms; the base is provided with a tool post slideway, and two ends of the front and the rear tool posts are arranged on the tool post slideway through slide blocks which are sleeved on a sliding leading screw; two compression rollers are arranged on the front tool post in parallel, one compression roller is arranged on the rear tool post, and the three compression rollers are arranged in a triangular shape; the base is provided with a rotary motor which is matched with the round timber clamping mechanisms through a triangular belt, a driven wheel and a big gear wheel, and the driven wheel is matched with a cutting feed speed reducer, a rear transmission gear box, a rear driving shaft and the sliding leading screw; the compression roller rotating motor is matched with the front tool post compression roller; and the motors are connected with a master control system of a computer control cabinet through conducting wires, and an integrated circuit chip is arranged in the computer control cabinet. The numerical control card-less rotary cutter solves the technical problems of rotary cutting bending and fluttering of thin round timbers and operation semi-automation in the prior art.

Description

technical field [0001] The invention belongs to the technical field of log veneer machinery, and in particular relates to a numerically controlled card-free rotary cutting machine. Background technique [0002] The rotary cutting machine of the prior art comprises a base, a front and rear knife table, a front and rear knife table motion motor, a pressure roller, a pressure roller speed change system and a pressure roller rotation motor; A log clamping mechanism is provided; the base is provided with a knife table slide rail, the two ends of the front and rear knife tables are respectively arranged on the knife table slide rails through sliders, and the slide block is set on the sliding screw. The rotary cutting machine with this structure will bend and vibrate when the diameter of the log is rotary cut to a thinner during the log rotary cutting process. Usually, the pressure bar is used to press the top of the knife table to reduce the vibration of the log. , due to the unb...
