Description

Wood core fence cutting and forming equipment

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 remainder of eucalyptus veneer production, namely the wood core after veneer rotary cutting. The eucalyptus is mainly used for rotary cutting single boards and used as raw materials for producing plywood and fine wood boards. After the eucalyptus is rotary-cut per cubic meter, the wood core residues of 0.07-0.1 cubic meter are produced, and the number of the eucalyptus wood cores is about 400 ten thousand cubic meters each year. The raw materials mainly originate from Shaoguan, north and Jiangxi juncture, river source, peace and other areas, and Jiangxi Gannan areas. The output of eucalyptus wood cores is more than 20 ten thousand cubic meters per year in North Guangdong region bordering Jiangxi through investigation, and the requirements of the project are met.

The diameter of the wood core is between 2.3cm and 3.0cm, and the wood core is directly used for producing the phenomenon of easy warp deformation and cracking. At present, the wood core is mainly utilized in the mode that the wood core is firstly processed into cuboid small wood strips or blocks through a series of procedures such as sawing, milling and the like, and then glued into boards such as joinery boards, integrated boards and the like, so that the added value of products is low; when the method is used for saw material production, the diameter grade is small, and the yield of the traditional sawing method is low. The utilization rate of the wood core is low, the produced board also can not meet the requirements of large-breadth thin boards with the thickness of 5 mm-20 mm required in the fields of furniture, floors, decoration and the like, and the board is mainly used for papermaking, artificial board production and the like at present. In order to improve the wood core yield, expand the application field of the wood core and improve the added value of wood core products, researchers propose a new wood core processing and utilizing method: the wood core is planed into a hexagon, and a part of the hexagon wood core is simultaneously split and arranged into the honeycomb structure integrated material.

The automatic integrated device for processing and cutting the log blocks with the wood core according to the patent number 201520103250.8 comprises a front guide groove, wherein a conveying device is arranged on the upper portion of the front guide groove, two V-shaped planes are arranged on the upper portion and the lower portion of the rear portion of the front guide groove, parallel double saw blades which are vertically arranged in a left-right symmetrical mode are arranged on the rear portion of each V-shaped plane, a rear guide groove is further arranged on the rear portion of each parallel double saw blade, a compression roller is arranged on the upper portion of each rear guide groove, and a single saw blade is arranged on the rear portion of each compression roller. However, the feeding speed is low, the two V-shaped planes are arranged symmetrically up and down, the resistance between the wood core log block and the V-shaped planes is large, and the cutting effect of the two V-shaped planes on the wood core log block is not known; the processing technology is crude, and the dimensional accuracy and the surface quality of the small hexagonal prism cannot be guaranteed, so that the quality of the glued laminated wood is affected. Therefore, the coarse small hexagonal prism is required to be finished, 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 the wood is inconsistent, the internal stress of the laminated wood after gluing is overlarge, and the defects of cracking, deformation and the like are easily generated.

For example, by adopting the design of a small-diameter six-prism accurate forming machine proposed by Hao Jingdong of Nanjing forestry university and the like, the coarse small six-prism is subjected to finish machining, the diameter specification (the inscribed circle diameter of the small six-prism) of the workable wood is 70, 100 and 150mm, the maximum length of the workpiece is 3000mm, and the minimum length is 400mm. The precise forming machine consists of 4 cutter shafts, including 2 vertical cutter shafts and 2 horizontal cutter shafts, wherein the cutter shafts are respectively provided with a combined milling cutter with an included angle of 120 degrees for processing left and right 4 faces of a hexagonal prism; the upper and lower horizontal cutter shafts are respectively provided with a planer tool for processing the upper and lower planes of the hexagonal prism. The feeding device is in a needling crawler-type structure, small needling is arranged on the outer side surface of the crawler, the needling penetrates into the upper surface of the small hexagonal prism under the compression of the air cylinder, and the workpiece is driven to feed under the action of needling meshing force. It suffers from a number of drawbacks: (1) During production and processing, for small hexagonal cylinders with different specifications, 4 cutter shafts are required to be adjusted at the same time, the left and right vertical plane cutters are V-shaped combined milling cutters, manual adjustment is time-consuming and labor-consuming, and the precision is difficult to ensure; (2) Considering the interference condition of a workbench and a cutter, the left side and the right side of the workbench are cut off to form a part, so that the workbench is narrower, a workpiece is not stable enough in the feeding process, and the cutter shaft mounting arrangement is required to be optimized; (3) The side pressing device is 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 needling track feeding structure is high, and the needling track feeding structure is difficult to popularize and apply.
