Description

Wood core rail cutting former

Technical Field

The invention relates to the technical field of wood processing equipment, in particular to wood core fence cutting and forming equipment.

Background

The main raw material for producing the wood core laminated wood is the residue of eucalyptus veneer production, namely the wood core after veneer rotary cutting. Eucalyptus is the main artificial forest tree species in south China, especially in Guangdong and Guangxi provinces, and the annual harvest and production amount is about 5000 million cubic meters. Eucalyptus is mainly used for rotary cutting of veneers at present and is used as a production raw material of plywood and fine wood boards. The rotary cutting of each cubic meter of eucalyptus produces about 0.07-0.1 cubic meter of wood core residues, and the quantity of the eucalyptus wood cores is only about 400 ten thousand cubic meters per year. The raw materials mainly come from Guangxi, Shaoguan, Heyuan, peace and other areas where North and Jiangxi are in the boundary, and Jiangxi south area. The investigation shows that the yield of the eucalyptus wood core is more than 20 million cubic meters every year in North Guangdong areas which are in the junction with Jiangxi, and the requirement of the project is greatly met.

The diameter of the wood core is between 2.3cm and 3.0cm, and the wood core is directly used for production and is easy to generate warping deformation and cracking phenomena. At present, the utilization mode of the wood core is mainly that the wood core is processed into a cuboid small batten or wood block through a series of working procedures such as sawing, milling and the like, and then the small batten or wood block is glued into boards such as a core-board and an integrated board, and the added value of the product is low; when the sawing machine is used for sawing materials, the traditional sawing method has low yield due to small diameter grade. The utilization rate of the wood core is low, the produced board can not meet the requirement of a large-breadth thin plate with the thickness of 5 mm-20 mm required in the fields of furniture, floors, decoration and the like, and the wood core is mainly used for papermaking, artificial board production and the like at present. In order to improve the wood core outturn percentage, expand the application field of the wood core and improve the added value of the wood core product, researchers provide a new wood core processing and utilizing method which comprises the following steps: and planing the wood core into hexagons, simultaneously, oppositely cutting a part of the hexagons and arranging the hexagons into the honeycomb-structure laminated wood.

"a log core log piece processing dissects automatic integrative equipment" like patent No. 201520103250.8, including preceding guide slot, its upper portion installs conveyer, and two V-arrangements are planed to preceding guide slot rear portion upper and lower, and V-arrangement is planed the rear portion and is installed left and right symmetry and set up the parallelly connected two saw bits of perpendicular installation again, still installs the back guide slot at parallelly connected two saw bit rear portions, and the compression roller is installed on the upper portion of back guide slot, is equipped with the single saw bit at the compression roller rear portion. However, the feeding speed is low, the two V-shaped planers are arranged symmetrically up and down, the resistance between the wood core log block and the V-shaped planers is large, and how to ensure the cutting effect of the two V-shaped planers on the wood core log block is unknown; the machining process is rough, and the dimensional accuracy and the surface quality of the small hexagonal prism cannot be guaranteed, so that the quality of the glued integrated material is influenced. Therefore, the rough small hexagonal prism needs to be subjected to finish machining, so that the dimensional accuracy and the surface quality of the small hexagonal prism are ensured, otherwise, the small hexagonal prism is stressed unevenly during gluing, the compression ratio of wood is inconsistent, the internal stress of the glued integrated material is overlarge, and the defects of cracking, deformation and the like are easily generated.

For example, the design of a small-diameter hexagonal prism precise forming machine proposed by quan of quaggong of Nanjing forestry university, etc., the rough small hexagonal prism is finely processed, the diameter specification (inscribed circle diameter of the small hexagonal prism) of the processed wood is 70, 100 and 150mm, the maximum length of a workpiece is 3000mm, and the minimum length is 400 mm. The precise forming machine consists of 4 cutter shafts, comprises 2 vertical cutter shafts and 2 horizontal cutter shafts, wherein the vertical cutter shafts are respectively provided with a combined milling cutter with an included angle of 120 degrees for processing the left surface and the right surface of a hexagonal prism; the upper and lower horizontal cutter shafts are respectively provided with a flat planer tool for processing the upper and lower planes of the hexagonal prism. The feeding device is of a needling crawler-type structure, a small needle is arranged on the outer side face of the crawler, the needle penetrates into the upper surface of the small hexagonal prism under the compression of the cylinder, and the workpiece is driven to feed under the action of the needling occlusion force. It has a number of drawbacks: (1) during production and processing, for small hexagonal prisms of different specifications, 4 cutter shafts are required to be adjusted simultaneously, and the left and right vertical plane cutters are V-shaped combined milling cutters, so that manual adjustment is time-consuming and labor-consuming, and the precision is difficult to guarantee; (2) considering the interference condition of the workbench and the cutter, the left side and the right side of the workbench need to be partially cut off, so that the workbench is relatively narrow, a workpiece is not stable enough in the feeding process, and the installation and the arrangement of the cutter shaft need to be optimized; (3) a side pressing device is also needed to press the side of the workpiece, so that the workpiece can be tightly attached to the side backer, and the machining precision of the workpiece is improved; (4) the manufacturing and processing difficulty of the needled crawler feeding structure is high, and the needling crawler feeding structure is difficult to popularize and apply.
