Description

Bamboo wood slitting device capable of changing tools in rotating mode

Technical Field

The utility model belongs to novel bamboo timber processing machinery specifically is a strip device is opened to bamboo timber of rotatable tool changing.

Background

China is a world with bamboo production mainly, bamboo resources are rich and the growth cycle is short, and the bamboo is an ideal material for replacing wood in various application occasions, but before raw bamboos are made into processable bamboo materials, a large number of processing procedures are involved, such as cutting, green peel removing, tabasheer removing, bamboo joint removing, planing and the like of the bamboo are involved, the processing quality and cost of the procedures directly influence the utilization efficiency and economic benefit of the bamboo, so that mechanical equipment required by each processing technology needs to be researched, and equipment support is provided for efficient and low-cost application of the bamboo.

The existing bamboo processing is mainly finished manually or simply by machinery, the traditional processing tool has the disadvantages of large workload, long consumed time and great requirement on the proficiency of operators, so that the production cost is high, the processing efficiency is low, the safety performance is poor, and the requirements on high-efficiency and high-quality bamboo processing and production cannot be met. Meanwhile, the bamboo and wood products cannot be accepted by the market due to poor working conditions and low technical level and incapability of acquiring more labor force, thereby being in a disadvantage.

In recent years, the market has recently started to research and develop numerical control bamboo splitting machines, but because the diameters of the bamboo canes are different, the cutters used for splitting and splitting the bamboo are also different, the cutters of the bamboo splitting machines in the current market mostly adopt manual cutter changing, the operation is complex, and the specification of the bamboo is not easy to control.

Aiming at the problem of tool changing, the design of an automatic tool changing mechanism of a numerical control bamboo cutting machine and the principle thereof [ J ] Western forestry science [ 2015(02):59-62] are designed according to the problems of the chen force, such as the chen force, etc. [ the design of the automatic tool changing mechanism of the numerical control bamboo cutting machine [ J ]. the automatic tool changing mechanism of the numerical control bamboo cutting machine is mainly designed into equipment for automatically changing a blade, a proper tool in a tool magazine is transversely pushed out according to the requirement, and then the tool is longitudinally fixed on a tool disc by a push rod. However, the design cannot guarantee the accuracy of tool changing, how to fix the tools accurately with the cutter head is not described in detail, and meanwhile, all the tools are placed on the tool rest and then selected, so that the overall structure is too large, the tool changing step is too complex, and the tool changing cannot be completed quickly, accurately and safely.

All Xiaoli of Nanning institute of occupational technology [ Zhuxiali, technical improvement research of bamboo breaking machine in bamboo stick forming machine

[J] 10-13, the bamboo breaking machine in the bamboo stick forming machine is researched, and an automatic modification scheme that a pneumatic manipulator and a feeding device are arranged on the original bamboo breaking machine is provided. The scheme of the device provides that a 3-degree-of-freedom mechanical arm is added in front of the feeding mechanism, so that the measurement of the mechanical centering and the diameter of the bamboo wood can be completed, and the accurate selection of the cutter is facilitated. Meanwhile, the proposal also provides that the automatic feeding is completed by a conveyor belt at the tail end. However, the slitting machine is generally used in small and medium-sized bamboo and wood processing factories, and the mechanical arm inevitably causes the equipment cost to rise, which leads to the product cost of the factories to rise. Meanwhile, after the mechanical arm measures the inner diameter, the tool still needs to be manually selected, and the fundamental problem is not solved.

Design of sun-dawn of the academy of forestry sciences of Hubei province [ Sun-dawn, Yi Hua, Dingding' an, Li Yang, bamboo wood to inner section breaking bamboo machine [ J ]. Hunan forestry science and technology [ 2009 (05); 15-18] and the like on the basis of the original impact type bamboo breaking machine, and an elastic clamping type inner-segment removing bamboo breaking machine is designed. The equipment integrates the strip cutting and inner section removing procedures, a strip cutting blade is arranged at the front end of a cutter head, and an inner section removing cutter is additionally arranged at the tail end of the cutter head, so that the inner section removing of bamboo materials is completed after the strip cutting. The cutter head structure of the equipment is complex, the bamboo breaking and inner joint removing can not be well coordinated, the quality of the inner joint removing is influenced, and the strip cutting quality can not be guaranteed.

Equally because the bamboo machine of cuing open in market adopts manual tool changing mostly, and manual heart relies on the chain drive to carry out the pay-off, and whole mechanical efficiency is not high, and the accuracy also can't guarantee, to above-mentioned problem, the high-efficient bamboo timber slitting device of this patent disclosure rotatory tool changing can accomplish quick free tool changing, adopts the high-efficient cutting bamboo timber of lead screw structure.
