Abstract
The invention discloses a method for improving the artificial pine forest peeling efficiency. The method comprises the following steps: selecting artificial pine forest wood with the diameter of 10-30cm as a raw material, and before peeling the raw material with a wood peeling machine, performing the following steps in sequence: 1, carrying out sealing treatment on the raw material to prevent water used as a pressure transmitting medium from permeating into the raw material during pressure processing; and 2, carrying out pressure keeping treatment on the sealed raw material under the pressure of 200-400Mpa for 2-5 minutes. According to the method, the shearing stress of a peeling knife required for peeling the artificial pine forest can be reduced to be below 10 kgf/cm＜2＞, so that the artificial pine forest peeling efficiency can be improved.
Description
Technical field
The present invention relates to wood processing field, more particularly to a kind of method for improving artificial forest Masson Pine peeling efficiency.
Background technology
Timber peeling is the important procedure in the timber course of processing, and before the eighties in 20th century, the peeling of China timber is always
Based on artificial, high labor intensive, low production efficiency.Late 1980s, China just developed first generation log bark removing machine product
Product, so far, realize the mechanization of timber peeling substantially.However, also there is a lot, master in existing timber peeling technology
Show that technical equipment power demand is big, in high energy consumption.This is primarily due to, it usually needs larger shearing force could be realized
The peeling of timber, the spud shear pressure stress needed for usual Masson Pine peeling are 150-200kgf/cm2.This undoubtedly improves
The power requirement of peeling machine, the material performance requirement of spud and horsepower requirements.A kind of convenient, timber peeling of low energy consumption
Technology is urgently researched and developed, but this must solve the problems, such as that spud shear stress is big needed for timber peeling.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of method for improving artificial forest Masson Pine peeling efficiency, due to adopting
The spud shear stress needed for artificial forest Masson Pine peeling obtained by the method for the present invention can be reduced to 10kgf/cm2Below；Cause
This can improve artificial forest Masson Pine peeling efficiency.
In order to solve above-mentioned technical problem, the present invention provides a kind of method for improving artificial forest Masson Pine peeling efficiency：Choose
The artificial forest pine timber of a diameter of 10-30cm (5-20 lifes) is raw material, is carrying out peeling to raw material using log bark removing machine
Before, first following steps successively：
1. raw material is carried out into encapsulation process, to prevent the water in pressing process as transmission medium from penetrating into raw material (wood
Material)；
2., by the raw material after encapsulation process, under the pressure of 200-400Mpa, pressurize processes 2-5 minutes (in supertension processing
Carry out in container).
As the improvement of the method for the raising artificial forest Masson Pine peeling efficiency of the present invention：The step 1. in, raw material is entered
Row polyethylene plastic film is wrapped up, so as to realize sealing.
As the further improvements in methods of the raising artificial forest Masson Pine peeling efficiency of the present invention：2. step is by sealing
The pressurize under the pressure of 400Mpa of raw material after reason is processed 5 minutes.
The purpose of the present invention is that artificial forest Masson Pine raw material (belt leather) is entered horizontal high voltage under the high static pressure of 200-400MPa to add
Work, as a result finds, the spud shear stress needed for artificial forest Masson Pine peeling after the high voltage units for finally giving can be reduced to
10kgf/cm2Below.
In the present invention, the process chamber diameter of extra-high tension unit is typically based on, and diameter is chosen in 10-30cm (5-20
It is raw) artificial forest Masson Pine be raw material.
Mechanism of the present invention is explained as follows：
During supertension processing timber, veneer and the practical part of timber all can deform upon under stress, however, veneer and wood
The density and fibre structure of material practicality part has significantly difference, during deforming upon under stress, veneer and timber
Practical part can carry out deformation with different speed of deformation, and this causes veneer and the practical part of timber real in pressing process
Show and be separated from each other, and then the spud shear stress needed for follow-up peeling processing is significantly declined.
Artificial forest pine timber after being processed using sealing of the present invention and pressure processing, the peeling needed for its peeling
Knife shear stress can be reduced to 10kgf/cm2Below.Therefore, the present invention can easily, low energy consumption realize artificial forest Masson Pine
Peeling, so as to realize improving the efficiency of artificial forest Masson Pine peeling.
Specific embodiment
Embodiment：
From in March, 2014 fell, diameter below 10-30cm artificial forest Masson Pine, to choose artificial forest Masson Pine wood
Material carries out polyethylene plastic film parcel, sealing for raw material, is put in supertension processing container, carries out 2-5 point under 200-400MPa
The HIGH PRESSURE TREATMENT of clock dwell time, takes out after process.Using the adjustable log bark removing machine of shearing force to people before and after treatment
Work woods Masson Pine carries out peeling process, so as to obtain the spud minimum shear stress for realizing peeling processing.
Table 1～3 is the density correction data of the artificial forest Masson Pine of Jing different pressures and dwell time process.
It can be seen that, using above-mentioned process conditions, effectively the spud shear stress needed for peeling can be reduced to
10kgf/cm2Below.But pressure is too small or dwell time too short DeGrain, pressure is excessive or the dwell time long can make
Into timber crack, and then form waste material.
The artificial forest Masson Pine peeling institute that the Masson Pine Jing different pressures of 1,5 years raw 10-15cm diameters of table and dwell time are processed
Spud shear stress (the unit for needing：kgf/cm2)
The artificial forest Masson Pine peeling institute that the Masson Pine Jing different pressures of 2,12 years raw 16-22cm diameters of table and dwell time are processed
Spud shear stress (the unit for needing：kgf/cm2)
The artificial forest Masson Pine peeling institute that the Masson Pine Jing different pressures of 3,20 years raw 23-30cm diameters of table and dwell time are processed
Spud shear stress (the unit for needing：kgf/cm2)
Finally, in addition it is also necessary to it is noted that listed above is only several specific embodiments of the invention.Obviously, this
It is bright to be not limited to above example, there can also be many deformations.One of ordinary skill in the art can be from present disclosure
The all deformations directly derived or associate, are considered as protection scope of the present invention.
