Combined cutting tool for taking inner bamboo joints and tabasheers out of intact bamboo tube

Abstract

The invention discloses a combined cutting tool for taking inner bamboo joints and tabasheer out of an intact bamboo tube. When the combined cutting tool rotates and moves in axial direction, three tabasheer cutting blades 5 synchronously open and cling to the inner wall of the bamboo tube under action of centrifugal force, plural rear cutter teeth 14 on the external curved surface of the tabasheer cutting blades 5 take the tabasheer out, at the same time, the inner bamboo joints are taken out by a small wimble 1, a large wimble 2, an end face tooth 11 on the front end face of the tabasheer cutting blades 5 and the plural front cutter teeth 12 on the external curved surface thereof; a section of depth limiting face 13 without cutter teeth is arranged in the middle of the external curved surface of the tabasheer cutting blades 5 and is used for limiting the depth of tabasheer cutting; each tabasheer cutting blade is provided with a synchronizing pin 3; the synchronizing pin 3 can slidein the radial groove of a synchronizing grooved pulley 4, thus ensuring that the three tabasheer cutting blades 5 can synchronously open under action of centrifugal force and can synchronously retractunder action of a resetting spring 8.

Description

Technical field: [0001] The invention relates to a combined cutting tool in a bamboo processing method, in particular to a combined cutting tool for removing inner nodes and yellowing of whole bamboo tubes. Background technique: [0002] Moso bamboo is an important forest resource that is fast-growing, high-yielding, high-quality, and easy to regenerate and restore. It not only has a short growth cycle, but also has superior physical and mechanical properties. However, compared with wood, bamboo has geometric characteristics such as small diameter, thin wall and hollow wall, large taper, and most of its cross-section is ellipse, which brings many problems and difficulties to its processing and utilization. In order to obtain products with good quality and high added value, expand the application field of bamboo processing products, and improve the utilization rate of bamboo, it is necessary to use unique processing technology and processing methods to carry out deep process...

AI Technical Summary

Problems solved by technology

Due to the low production efficiency, it is impossible to meet the requirements of industrial production. Therefore, in the actual production of bamboo plywood, the bamboo tube can only be split into two halves, the septum is removed, and the yellowing is removed with a planer after being flattened in a press.

In the production of bamboo flooring, the cylindrical bamboo is divided into multiple equal bamboo slices in the radial direction, the septum is removed, and the planer is used for planing processing, and the fan-shaped cross-section bamboo slices are processed into equal width and thickness. Bamboo slices with a rectangular cross-section, the utilization rate of this method of yellowing is low
