Production method and forming device for cylindrical reconstituted bamboo lumber

Abstract

Provided is a forming device for cylindrical reconstituted bamboo lumber. A mold of the forming device is composed of an upper formwork (7), a lower formwork (25) and end covers (18). A cylindrical cavity is formed by the upper formwork (7), the lower formwork (25) and the end covers (18) in a surrounded mode. A square window with the width being D and the length being larger than or equal to L is formed in the upper formwork, guiding plates (10 and 11) are arranged on the two long sides of the square window correspondingly, the distance between the inner walls of the two guiding plates is D, an arc pressing plate (9) is arranged between the two guiding plates, and a vertical feeding channel is jointly formed by the two guiding plates and the arc pressing plate. A driving roller set (6) inclining towards the square window is mounted above the mold, and a material pressing system is composed of a motor (21), a transmission part thereof and the arc pressing plate (9). A method for producing the cylindrical reconstituted bamboo lumber includes the first step of manufacturing triangular bamboo splits, the second step of drying, gluing and re-drying, the third step of mounting special equipment, the fourth step of feeding, the fifth step of pressing, the sixth step of solidifying and the seventh step of demolding and discharging. By means of the device and method for producing the cylindrical reconstituted bamboo lumber, raw bamboo is saved, the density is low and uniform, pressure is small, stability is good, and production cost is low.

Description

technical field [0001] The invention relates to a production method of recombined bamboo and a forming device thereof, in particular to a method for producing cylindrical recombined bamboo with triangular long bamboo strips as raw materials and a special device thereof. Background technique [0002] my country's bamboo forest area ranks first in the world. Bamboo can be grown in 4 years. Under the guidance of sustainable development, the continuous development and sustainable use of biological materials is a project of great significance. [0003] At present, the utilization of bamboo is mainly used to produce decorative materials such as recombined bamboo flooring or sliced ​​thin bamboo. The molds used are cuboid steel molds of different specifications. Requirements for the production of wood grain recombined decorative materials.

AI Technical Summary

Problems solved by technology

[0003] At present, the utilization of bamboo is mainly used to produce decorative materials such as recombined bamboo flooring or sliced ​​thin bamboo. The molds used are cuboid steel molds of different specifications. Requirements for the production of wood grain recombined decorative materials

[0004] CN104589423A announced "a kind of wood forming control head", and CN102145503A announced "a production method for manufacturing artificial wooden squares and its special forming mold". The wooden squares made by the above two patented molds are all rectangular or square. , and the format is small, it is impossible to make cylindrical materials

[0005] In order to overcome the existing planed recombined bamboo and sliced ​​thin bamboo that need to be lengthened and widened to meet the production requirements of imitation wood-grain recombined decorative materials, the present invention proposes a production method of bamboo solid cylinder and its special forming mold. And market research, have not yet seen relevant reports and products on the market
