Description

A Rotary Cutting Process for Logs with Large Sharpness

technical field

The invention belongs to the field of wood processing, and more specifically relates to a rotary cutting process of logs with large sharpness.

Background technique

Rotary cutting is a process in which the wood section is rotated on a fixed axis until the blade is parallel to the axis of the wood section for linear feed motion, and the cutting is carried out along the direction of the wood rings. General trees have sharpness and curvature, especially artificial fast-growing trees, whose characteristics of high planting density and fast growth rate will also increase the sharpness of logs. In the production of wood-based panels, due to the large natural forest The reduction of diameter wood makes the utilization of small diameter wood and the output of processing surplus products increase. For this reason, the present invention proposes a rotary cutting process with a log with a large sharpness.

Contents of the invention

The object of the present invention is to provide a rotary cutting process of logs with a large degree of sharpness, so as to solve the problems raised in the above-mentioned background technology.

To achieve the above object, the present invention provides the following technical solutions:

A kind of rotary cutting processing technology with large sharpness logs, comprising the following steps:

S1, first measure the taper of the log, take the axis of the log as the basic line, set it to 0°, and determine the angle between the edge line of the log and the basic line;

S2. Clamp the log on the rotary cutting machine through the clamping shaft, adjust the center line of the clamping shaft to coincide with the axis of the log itself, the center line of the clamping shaft is the axis of the log, slowly approach the rotary cutting blade to the rotary shaft, and adjust the inclination angle of the blade line of the cutting blade With the size of the cutting angle, the angle between the edge line of the log and the basic line is used as a reference, and the edge line of the cutting blade is set to be consistent with the angle between the axis of rotation and parallel to the edge line of the log;

S3. The log rotates under the joint drive of a pressure roller, a transmission roller and a push wheel. The pressure roller, transmission roller and push wheel fix the log, and the transmission roller is used to drive the log to rotate. The push wheel and the rotary cutting blade are relatively fixed. And it moves together under the action of the feeding mechanism. When the log is gradually reduced during the rotary cutting process, the distance between the rotary cutting blade and the edge of the log is guaranteed to be constant. One side of the rotary cutting blade is also equipped with a pressure gauge, which is the same as the rotary cutting blade. Both are driven by the feed mechanism and move together, and the angle and position of the pressure gauge can be adjusted;

S4. The drive roller rotates under the action of the motor to drive the log to rotate, and the rotary cutting blade rotates the veneer from the log;

S5. Collect the wood fragments from the initial cutting for backup. The neatly cut veneers are stacked neatly and placed in a cool and dry environment to avoid the environment from affecting the quality of the veneers.

Preferably, after the position and angle adjustment of the rotary cutting blade in S2 is completed, the clamping shaft is returned, so that the log is separated from the clamping shaft and sent between the pressing roller, the driving roller and the driving wheel.

Preferably, a wood peeling machine is used to remove the log skin before the log sharpness measurement in S1.

Compared with the prior art, the beneficial effect of the present invention is that the rotary cutting blade is installed in the way of edge positioning, compared with the traditional way of installing in the center, more veneers can be processed, and the installation mode of edge positioning, The sapwood part of the log is more fully utilized, the processing residue generated by the sapwood part during the rotary cutting process is reduced, and the mechanical properties of the glued wood product made by cutting the veneer are improved.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

A kind of rotary cutting processing technology with large sharpness logs, comprising the following steps:

S1, first measure the taper of the log, take the axis of the log as the basic line, set it to 0°, and determine the angle between the edge line of the log and the basic line;

S2. Clamp the log on the rotary cutting machine through the clamping shaft, adjust the center line of the clamping shaft to coincide with the axis of the log itself, the center line of the clamping shaft is the axis of the log, slowly approach the rotary cutting blade to the rotary shaft, and adjust the inclination angle of the blade line of the cutting blade With the size of the cutting angle and the angle between the edge line of the log and the basic line as a reference, the edge line of the cutting blade is set to be consistent with the angle between the axis of rotation and parallel to the edge line of the log;

S3. The log rotates under the joint drive of a pressure roller, a transmission roller and a push wheel. The pressure roller, transmission roller and push wheel fix the log, and the transmission roller is used to drive the log to rotate. The push wheel and the rotary cutting blade are relatively fixed. And it moves together under the action of the feeding mechanism. When the log is gradually reduced during the rotary cutting process, the distance between the rotary cutting blade and the edge of the log is guaranteed to be constant. One side of the rotary cutting blade is also equipped with a pressure gauge, which is the same as the rotary cutting blade. All are driven by the feed mechanism and move together, and the angle and position of the pressure gauge can be adjusted;

S4. The driving roller rotates under the action of the motor to drive the log to rotate, and the rotary cutting blade rotates the veneer from the log;

S5. Collect the wood fragments from the initial cutting for backup. The neatly cut veneers are stacked neatly and placed in a cool and dry environment to avoid the environment from affecting the quality of the veneers.

Specifically, after the position and angle adjustment of the rotary cutting blade in S2 is completed, the card shaft is returned, so that the log is separated from the card shaft and sent between the pressure roller, the transmission roller and the push wheel.

Specifically, before the log sharpness measurement in S1, the log skin is removed by using a wood peeling machine.

First measure the angle between the edge line of the log and the center line as the angle adjustment standard of the rotary cutting blade, adjust the inclination angle of the rotary cutting blade on the rotary cutting machine according to this standard, make the edge line of the rotary cutting blade parallel to the edge line of the log, and start the rotary cutting machine , During the process of log rotation, the rotary cutting blade is gradually fed, and the log can be processed into a veneer.
