Automatic adjustment device for rotating knife parallel to outer bamboo wall, bamboo shaping and rotary cutting machine, and method for parallel bamboo wall rotary cutting

Abstract

The invention discloses an automatic adjustment device for rotary knives parallel to the outer bamboo wall, a bamboo material shaping and rotary cutting machine and a method for parallel bamboo wall rotary cutting. end; angle adjustment seat, the other end of the knife holder is arranged on the angle adjustment seat, and the angle adjustment seat includes a brake stepping motor, and the brake stepping motor makes the knife holder rotate around the hinged end; the rotary knife parallel adjustment control system uses It is used to control the rotation of the brake stepper motor so that the rotary knife is parallel to the outer bamboo wall. The method is based on the bamboo shaping and rotary cutting method, and the bamboo veneer is rotary cut after the rotary knife is automatically adjusted to be parallel to the outer bamboo wall before the rotary cutting knife enters. The device and method of the present invention can rotary cut a very complete bamboo veneer with excellent performance, the output rate is high, and only a few fibers are cut by the rotary knife, the rotary cutting resistance is small, the quality of the bamboo veneer is good, and the energy consumption is low .

Description

technical field [0001] The invention relates to the field of wood-based panels, in particular to an automatic adjustment device for rotary knives parallel to outer bamboo walls, a bamboo shaping and rotary cutting machine and a method for parallel bamboo wall rotary cutting. Background technique [0002] In the commonly used wood rotary cutting machine, the blade of the rotary knife is parallel to the center line of the wood section. Because the wood section has a small taper, the blade of the rotary knife is approximately parallel to the longitudinal direction of the fiber of the wood section. vertical. In the rotary cutting of bamboo, in the commonly used bamboo rotary cutting machine, the blade of the rotary knife is still parallel to the rotation center line of the bamboo section, but the bamboo wall is thin, with an average thickness of only about 10mm, and the tapering of the bamboo section is relatively large, resulting in The blade of the rotating knife intersects w...

AI Technical Summary

Problems solved by technology

However, since the bamboo section is driven by friction to rotate, the surface linear velocity of the bamboo section is equal to the linear velocity of the friction roller, and the diameter of the bamboo section is different in the length direction, which will cause the rotational speed to be different along the length direction of the bamboo section, which will cause the bamboo section to twist and jump. The surface is slippery, so that the surface quality of the bamboo veneer produced by rotary cutting is poor, the thickness is uneven, and the friction torque is small, so thicker bamboo veneer cannot be produced by rotary cutting
