Description

A bamboo slitting device capable of rotating and changing knives

technical field

The utility model belongs to the field of novel bamboo material processing machinery, in particular to a bamboo material slitting device which can rotate and change knives.

Background technique

my country is the main bamboo-producing country in the world. Bamboo is rich in resources and has a short growth cycle. It is an ideal material to replace wood in many applications. Bamboo harvesting, cutting, removing green skin, removing bamboo yellow, removing bamboo knots, planing, etc. The processing quality and cost of the above processes directly affect the utilization efficiency and economic benefits of bamboo, so it is necessary to study the mechanical equipment required by each processing technology. , to provide equipment support for the efficient and low-cost application of bamboo.

The existing bamboo processing is mainly done by hand or simple machinery. The traditional processing tools require a large amount of work and take a long time. At the same time, there are great requirements on the proficiency of the operators, so the production cost is high and the processing time is high. Low efficiency and poor safety performance cannot meet the needs of high-efficiency and high-quality bamboo processing and production. At the same time, due to poor working conditions and low technical level, it is impossible to obtain more labor, resulting in bamboo and wood products not recognized by the market, and thus at a disadvantage.

In recent years, the market has begun to develop CNC bamboo cutting machines. However, due to the different diameters of bamboo materials, the cutting tools used for cutting bamboo strips are also different. At present, the cutting tools of bamboo cutting machines on the market mostly use manual tool change, which is cumbersome to operate. Bar specifications are not easy to control.

Aiming at the problem of tool change, Xing Liping [Xing Liping, Bao Yuying, Ren Hong'e. Design and principle of automatic tool changing mechanism of CNC bamboo cutting machine [J]. Western Forestry Science. 2015(02):59-62] designed CNC bamboo cutting machine automatic tool change mechanism, this design mainly designs a device for automatic blade replacement, which pushes out the appropriate tool in the tool magazine horizontally according to the demand, and then the push rod vertically fixes the tool to the cutter head. However, this design cannot guarantee the accuracy of tool change. How to fix the tool accurately and the cutter head is not described in detail. At the same time, all the cutters are placed on the cutter holder and then selected. The overall structure is too large. Too complicated to complete the tool change quickly, accurately and safely.

Zhu Xiaoli of Nanning Vocational and Technical College

[J].Modern Manufacturing Technology and Equipment. 2014(03):10-13] The bamboo breaking machine in the bamboo stick forming machine was studied, and the automatic transformation plan of installing a pneumatic manipulator and a feeding device on the original bamboo breaking machine was proposed. The equipment plan proposes to add a 3-DOF manipulator before the feeding mechanism, which can complete the mechanical alignment of the bamboo and the measurement of the diameter of the bamboo, which is convenient for the precise selection of tools. At the same time, the scheme also proposes to use the conveyor belt to complete the automatic feeding at the end. However, the opening machine is generally used in small and medium-sized bamboo and wood processing factories, and mechanical gestures will inevitably increase the cost of equipment, resulting in an increase in the cost of factory products. At the same time, after the manipulator measures the inner diameter, it is still necessary to manually select the tool, which does not solve the fundamental problem.

Sun Xiaodong from Hubei Academy of Forestry [Sun Xiaodong, Yin Hua, Ding Dingan, Li Yang. Design of bamboo cutting machine for removing inner knots from bamboo [J]. Hunan Forestry Science and Technology. 2009(05); 15-18], etc. in the original impact type bamboo breaking machine On the basis of the transformation, the elastic clamping type bamboo breaking machine is designed. The equipment combines the two processes of slitting and removing inner knots into one. The front end of the cutter head is designed as a slitting blade, and the inner knot cutting tool is added at the end of the cutter head, so that the bamboo can be removed from the inner knot after the slitting. The structure of the cutter head of this equipment is relatively complex, and the processing of bamboo breaking and inner section removal cannot be well coordinated, which affects the quality of inner section removal, and also leads to the inability to guarantee the quality of opening.

Also, because most of the bamboo cutting machines in the market use manual tool change, manual centering, and rely on chain drive for feeding, the overall mechanical efficiency is not high, and the accuracy cannot be guaranteed. In view of the above problems, this patent discloses an efficient rotary tool change. The bamboo slitting device can complete the quick and free tool change, and use the lead screw structure to cut bamboo efficiently.
