Research And Design Of Engineering Straw Curtain Cloth Machine

Straw curtain is a kind of straw woven fabric widely used in industry,agriculture and business,which has great potential for development.Among them,engineering straw curtain is an important part of straw weaving fabric,thickness is thinner than insulation straw curtain,but the level of mechanization is low.A new type of finger-type engineering grass curtain cloth machine is designed,the main contents are as follows:First,by analyzing the technical utilization of rice straw and the production status of straw curtain in China,the paper puts forward that straw curtain can be divided into thermal insulation straw curtain and engineering straw curtain according to the different application occasions,and describes the characteristics of thermal insulation straw curtain and engineering straw curtain.Through the study of the grass pattern of the insulated straw curtain weaving machine,the grass curtain weaving machine could not complete the project,and the paper put forward the research and development of the automatic grass curtain weaving machine.Second,through the study of grass cloth pattern,careless careless put forward the project of cloth grass,grass curtain of the project overall structure design of the grass machine,on the basis of detailed analysis of the mechanism motion process,has carried on the systematic engineering grass cord grass machine on the mechanical structure design,drive system design and control system design,use Soildworks on engineering grass cord grass machine for 3 d modeling,this paper expounds the working principle of engineering grass cord grass machine,designs the clamp device and CAM-grass device,cancelled the pneumatic drive system and independent grass device.PLC ladder diagram was prepared by GX developer.Thirdly,static analysis was carried out on the key components such as the fingers and the cams of the engineering grass curtain grass machine.According to the Simulation results,the deformation of the key components in the working process was small and the displacement change that met the design requirementswas achieved.Taking grass clip finger as an example,the wear resistance of the key components is analyzed.By calculating the ratio of wear resistance of different materials,it is decided to choose high manganese steel to make grass clip finger,CAM and other key components.Fourth,with controlled trial method to engineering grass cord grass machine product quality and the use of textile grass compared with people,with CRT,summarized on the test data,the following conclusions: using engineering grass cord grass machine for production,reducing labor four people,careless engineering were uneven degree of 18.03% or less,the average thickness is 7 mm,various aspects are better than one worker grass,has reached the design requirements.
