Abstract:In order to improve the transformation effect of collective doffing of FA506 spinning frame short vehicle，the structure of FA506 spinning frame and the transmission guide rail structure of tray conveying mechanism of bracing type with transmission rod and bracing type with strut collective doffing structure with single convex disc are introduced.Through the mechanical analysis of transmission guide rail and the analysis of two kinds of transformation forms，it is shown that under the same load of full yarn convex disc，the pull-force required by the bracing type with strut is smaller than that of the bracing type with transmission rod.The same specification cylinder can drive the full yarn convex disc with more spindles to work smoothly.There are two kinds of collective doffing transformation forms: no replacement of mid-wallboard and replacement of mid-wallboard，which should be selected according to user equipment conditions，factory conditions and spinning requirements，etc.Retention rate of doffing for the first mentioned of two after transformation can be controlled at 93%~98%，while retention rate of doffing for the last mentioned of two after transformation usually can be controlled at 96%~99%.
Key Words:FA506 spinning frame；short vehicle；collective doffing structure with single convex disc；bracing type with transmission rod；bracing type with strut；mid-wallboard；retention rate of doffing
