Research Of Car Composite Molded Ultra-fine Wood-flour Grinding Equipment

Since the1980s, many of the high-performance of new materials in large numbers, people are increasingly concerned about the development and application of new materials. Superfine wood flour is emerging in recent years, eco-friendly natural material, it has a broad application prospects such as luxury car interior wood trim, wood-plastic composite material, man-made carbon fiber, artificial membranes, environmental protection and other aspects. The wood matrix material, the use of ultra-fine wood flour do inevitably to some extent able to effectively solve our environmental protection and conservation of automotive interior materials situation, improve the comprehensive utilization of timber. And wood processing residues loop reuse, should also find a reasonable and efficient way. Therefore, the design for a wood flour ultrafine processing industrial equipment has a very important significance. It is not only beneficial reuse of surplus materials in wood processing, and are of great significance to improve economic efficiency, protect the environment, reduce production costs.The main content of this paper is to ordinary wood flour processed into car superfine wood flour composite molding processing equipment works. Papers from the wood cell force to proceed with the analysis, research and trends at home and abroad in recent years. Been optimized to improve the processing method of the processing equipment of existing wood flour and process. Traditional wood flour machine design are generally experience design, the paper design to take full account of the structure is reasonable, and static and modal analysis using finite element analysis machine. Optimized design, the structural strength of the weakest link and gradually explore a brand new ultra-fine wood flour machine structure and processing methods. Determined by the characteristics of the cross-sectionai shape of the wood cell structure in the form of cutting the box and cutting power required. Superfine wood flour cooling heat exchange equation, grading collect kinetic equation. Described car craft cutting box and wood the ultrafine composite molded wood flour machine’s airflow separation cooling method. In addition, according to the car with the composite molded superfine wood powder machine processing characteristics to determine the main technical parameters of equipment and machine parts were limited analysis verify the strength. After the prototype processing a large number of experiments, affect the processing efficiency, the impact of wood flour mesh, cutting and grinding bodies superfine wood flour experimental data, to verify the correctness of the design theory.High quality mesh superfine wood flour processing the car with the best raw materials for environmentally friendly interior materials, it can be an effective solution to the problem of environmental pollution of the traditional raw materials. Structural design and structural optimization of this thesis for the car with a composite molded ultra-fine wood flour grinding equipment to provide guidance and experience laid a foundation for the industrialization of the ultra-fine wood flour machine, can be effective in improving the existing products on the problem of environmental pollution.
