In order to solve the problem that small and medium-sized dyeing and finishing enterprises need mechanical equipment to realize the fabric packaging,the axiomatic design theory was used to analyze the functional requirements and structural design elements of the folding mechanism in the fabric packaging equipment according to the user's needs.The design scheme of the mechanism that complies with the axiom independence was proposed through coupling design analysis.A six-rod mechanism consisting of a crank slider mechanism and a cam mechanism in series on the right side was chosen as the design object.The displacement matrix method was used to obtain the dimensions of the crank slider mechanism,and the relationship between the slider position and the crank angle was analyzed.The laws of equal velocity motion and sinusoidal acceleration motion were selected to design the contour of the pushing stage and the contour of the return stroke respectively.Moreover,the motion simulation of the folding mechanism was carried out to obtain the angular displacement,angular velocity and angular acceleration curves of the folding plate.Analysis reveals that the motion characteristics of the folding plate meet the design requirements and satisfy the practical needs.
