Driving device for cold cathode lamp tube powdering machine

The invention discloses a driving device for a cold cathode lamp tube powdering machine. The driving device comprises a rail which is positioned in a powdering machine shell and connected with a chuck of the rail through a shaft and rotates around the circle center of the shell, and an operating window formed on the shell; the shaft of the chuck is rotationally connected with the rail; a driving wheel is arranged on the shaft; the driving wheel is in driving connection with a drive wheel through a driving belt; and a wheel shaft of the drive wheel is movably connected with the shell. In the driving device, the shaft of the chuck is rotationally connected with the rail and is provided with the driving wheel connected with the drive wheel through the driving belt, so a lamp tube can revolve one circle around the circle center of the shell and rotate with the rail when the lamp tube of which the inner wall is coated with slurry is clamped on the chuck. Due to a centrifugal force produced by rotation, residual slurry on the inner wall of the tube is thrown away from the tube quickly; therefore, the consistency of the thickness of the slurry on the inner wall of the tube and the quality of the lamp tube can be guaranteed.
