Mechanical Design And Dynamic Analysis For Main Motive Mechanisms Of Combing Machine

Combing machine speed is an important symbol of its technological level. As the combing machine speed increase, the output and labor productivity is higher, the floor space, labor force and electricity consumption is reduced. Therefore development of high-efficacy comber has enormous economic benefit. Main motive mechanism is the main driving system in combing machine. As the combing machine speed increase, the vibration of the primary motion mechanism also increases, and the noise and shock also increases. Carding quality, stability and reliability is reduced. Therefore, high-efficiency comber subject has important practical significance.In this paper, the main mechanism of cylinder gear mechanisms and detaching roller transmission mechanism innovative design was carried out. The development present situation, the process of combing machine and the main motion mechanism is studied, and the shortage of existing comber cylinder speed change mechanism and detaching roller driving mechanism is analysed. The implementation of the new scheme can significantly reduce the combing machine primary motion mechanism design and manufacturing cost and difficulty; Using servo motor to drive new detaching roller transmission mechanism can improve the quality of combed and strengthen the optimum spinning performance of the combing machine.On this basis, using the MATLAB optimization toolbox, relevant geometric dimensions of innovative mechanism is solved. Then, on the basis of the optimization design results, considering to avoid interference in the process of movement and select widely used parts, the structure of innovative mechanism is detailedly designed and a reasonable assembly scheme is determined. The CAD assembly model of innovative mechanism is built in SolidWorks.Finally, using the SolidWorks Motion, kinematics and dynamics model is simulated. Comparing the actual output movement curve with the target process curve, innovative mechanism is feasible and structural design is effective; Using SolidWorks Simulation, the finite element stress and strain of key components is obtained and the reliability of the new scheme structure design is validated.
