Mechanical System Design And Research On Take-up And Dynamically Adjustable Control For Tubular Fabric

3D tubular carbon fiber tube with a lightweight,high strength characteristics,has a very broad application prospects.So the machine with the capability of weaving 3D tubular carbon fiber tube should be developed.3D circular loom can weave 3D tubular carbon fiber tube by 3D textile processes.Its coiling system is responsible for the fabric take-up,keeping the fabric away from the formation region of the fabric,and provide enhance traction for weaving process.Due to the introduction of carbon fibers and other special fibers,the traditional coiling traction institutions must destroy the fabric.Therefor it is very necessary to breakthrough the traditional coiling traction technology,research and development a new winding system to meet the carbon fiber need.On the other hand,with the development of weaving techniques,the need to achieve the dynamic changes of the fabric caliber developed the loom the reducers control system is also very necessary for the expansion of the type of fabric products.The purpose of this project is to develop mechanical system on take-up and dynamically adjustable control for tubular fabric.The winding traction system must provide the required traction for fabric to enhance with the destruction of the carbon fiber tube avoided and the damage to the fabric reduced.For adjustable control systems,since the yarn presence of openings in the weaving process,so interference with the pair of openings of the yarn should be avoided to change fabric caliber smoothly.With the research on winding traction system in various types of looms.we find the existing traction coiling system will damage the carbon fiber tube.So combined with the actual situation of the 3D circular loom we determine to use hand gripping traction fabric traction.On the basis of the overall program,a more detailed study and design of the core components of the robot system should be done to meet the requirements on fabric traction assurance system.Through the research and analysis on adjustable control agencies at home and abroad,the deficiencies that exist in the application of the perspective loom can be found.We determine a cam-driven adjustable control program that meet the loom yarn up and down opening fabric upward traction process requirements.In order to ensure the reliability of the drive mode of the inner cam,we analyzed theoretically the working mechanism driven by the inner cam to provide a basis for optimization of the inner cam curve.Rely on this study,we can optimize the inner cam profile and determine the technical parameters of the drive motor,which provides support for the selection of the motor and adjustable control.For the 3D circular loom weaving process traction speed is not high,the take-up and adjustable speed control mechanical systems do not ask.This article mainly checks the static checking calculation and completes the 3D model of the take-up of the 3D circular loom and adjustable control of mechanical systems by Solidworks software.
