Efficient self-centering rotary cutter

Abstract

The invention discloses an efficient self-centering rotary cutter. In the rotary-cut process, a first lifting drive device drives a first lifting frame to lift and lower along a first guide frame until the center of a positioning cutting knife is roughly at the same height as the center of a log, a user operates a first operating handle to push a first sleeve body to move along a thread towards the log, the first sleeve body has inward pressure on a first positioning arm through a first top abutting sleeve, the first positioning arm performs clamping through a first top abutting gripper, and top abutting grippers of three positioning arms can perform all-dimensional clamping on the log. A first advance and retreat motor drives a first advance and retreat worm wheel to rotate through a first advance and retreat worm, the first advance and retreat worm wheel drives a first shaft body to slide towards the log through a first advance and retreat screw, a first blade is in contact with thelog in a top abutting mode and the log is rotated to cut a groove corresponding to a first conical head, a first end cover is automatically in contact with the groove formed by rotary cutting in a topabutting mode, and the self-centering effect is realized.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a high-efficiency automatic centering rotary cutting machine. Background technique [0002] At present, in the field of material cutting, the existing high-precision rotary cutting machines on the market are generally large in size and complex in structure. Before using the machine, the log needs to be centered. If the centering is not accurate, intermittent veneers will be unscrewed when the rotary cutting is started. Belt or narrow veneer. The more broken veneers or narrow veneers, the more good sapwood veneers are lost, which is not conducive to continuous production. [0003] The prior art discloses a high-precision wood processing rotary cutting machine with an application number of 201621000309.1, which includes a rear side plate, a frame, a cylinder, a first inclined plate, a strut, an abutment, a first sliding sleeve, and a first movable Rods, rollers, first springs, buttons, s...

[0003] The prior art discloses a high-precision wood processing rotary cutting machine with an application number of 201621000309.1, which includes a rear side plate, a frame, a cylinder, a first inclined plate, a strut, an abutment, a first sliding sleeve, and a first movable Rods, rollers, first springs, buttons, support rollers, etc.; the bottom of the front side of the rear side plate is provided with a frame, and the top of the frame is sequentially provided with a first slant plate, a support rod and an abutment from left to right, and the first slant plate The bottom end is hingedly connected to the top of the frame, and the lower part of the left wall in the frame is inclined to be provided with a cylinder, and the bottom of the cylinder is hingedly connected to the left wall inside the frame, but this prior art lacks a centering function and cannot automatically move logs. Alignment may lead to poor quality of wood chips produced by rotary cutting, especially intermittent waste of wood chips, which increases the economic cost of raw materials
