Description

A wood core fence cutting and forming equipment

technical field

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

Background technique

The main raw material for the production of wood-core veneer is the residue from the production of eucalyptus veneer—the wood core after rotary cutting of the veneer. Eucalyptus is the main plantation tree species in southern my country, especially in Guangdong and Guangxi provinces, with an annual harvest of about 50 million cubic meters. The main coating of eucalyptus at present is used for rotary cutting veneer, which is used as raw material for the production of plywood and thin wood. Each cubic meter of eucalyptus leaves about 0.07-0.1 cubic meters of wood core residue after rotary cutting, and the number of eucalyptus wood cores is about 4 million cubic meters per year. The raw materials mainly come from Shaoguan, Heyuan, Heping and other areas at the junction of Guangxi, the north and Jiangxi, as well as Jiangxi and southern Jiangxi. According to the investigation, the output of eucalyptus cores in the northern Guangdong region bordering Jiangxi is more than 200,000 cubic meters per year, which is far enough to meet the needs of this project.

The diameter of the wood core is between 2.3cm and 3.0cm, and it is easy to cause warping deformation and cracking when it is directly used for production. At present, the main way of utilizing the wood core is to first process the wood core into small rectangular wooden strips or blocks through a series of processes such as sawing and milling, and then gluing it into boards such as blockboard and integrated board. The added value of the product Low; when used for sawn timber production, due to the small diameter class, the yield rate of the traditional down sawing method is low. The utilization rate of wood core is low, and the produced boards cannot meet the needs of large-format thin boards with a thickness of 5mm to 20mm in furniture, flooring, decoration and other fields. In order to improve the yield of wood core, expand the application field of wood core, and increase the added value of wood core products, researchers proposed a new method of wood core processing and utilization: planing the wood core into hexagons, and simultaneously The hexagonal wood core is cut in half, and then arranged to form a honeycomb structure.

For example, the patent No. 201520103250.8, "a wood core log block processing and cutting automation integrated equipment", includes a front guide groove, the upper part of which is installed with a conveying device, and two V-shaped planers are arranged on the upper and lower parts of the rear of the front guide groove. After the V-shaped planer The left and right parallel double saw blades are installed symmetrically on the left and right, and a rear guide groove is installed at the rear of the parallel double saw blade. The upper part of the rear guide groove is installed with a pressure roller, and a single saw blade is installed at the rear of the pressure roller. . However, the feeding speed is small, the two V-shaped planers are arranged symmetrically up and down, and the resistance between the wood core log block and the V-shaped planer is very large. It is not known how to ensure the cutting effect of the two V-shaped planers on the wood core log block; processing; Due to the rough process, the dimensional accuracy and surface quality of the small hexagonal prism cannot be guaranteed, thus affecting the quality of the glulam after gluing. Therefore, it is also necessary to finish the rough small hexagonal prism to ensure the dimensional accuracy and surface quality of the small hexagonal prism. Otherwise, the small hexagonal prism will be subjected to uneven force during gluing, and the wood compression ratio will be inconsistent, resulting in Glulam after gluing. The internal stress is too large, which is prone to cracking, deformation and other defects.

For example, Hao Jingdong of Nanjing Forestry University and others proposed the "Design of Precision Forming Machine for Small-diameter Wood Hexagonal Cylinder", which is used for finishing the rough small hexagonal prism. 100, 150mm, the maximum length of the workpiece is 3000mm, and the minimum length is 400mm. The precision forming machine consists of 4 cutter shafts, including 2 vertical cutter shafts and 2 horizontal cutter shafts, wherein a combined milling cutter with an included angle of 120° is installed on each of the vertical cutter shafts to process the left and right sides of the hexagonal prism. 4 planes; a planing knife is respectively installed on the upper and lower horizontal cutter shafts to process the upper and lower planes of the hexagonal prism. The feeding device is of acupuncture crawler type structure. Small needles are installed on the outer side of the crawler. Under the pressing of the cylinder, the needles are inserted into the upper surface of the small hexagonal prism, and the workpiece is fed under the action of the acupuncture bite force. However, it has many defects: (1) During production and processing, for small hexagonal prisms of different specifications, 4 cutter shafts need to be adjusted at the same time, while the left and right vertical planers are V-shaped combined milling cutters. Manual adjustment is time-consuming and laborious, and the accuracy is difficult. Guarantee; (2) Considering the interference between the worktable and the tool, a part of the left and right sides of the worktable should be cut off, resulting in a narrow worktable, and the workpiece is not stable enough during the feeding process, and the installation and arrangement of the cutter shaft needs to be optimized; (3) ) It also requires a side pressing device to pressurize the side of the workpiece, so that the workpiece can be close to the side backing, thereby improving the machining accuracy of the workpiece; (4) The manufacturing and processing of the needle-punched crawler feed structure is difficult, and it is difficult to popularize and apply.
