Problems solved by technology

From the above-mentioned heating and drying process, it can be seen that the lamp tube suspended on the chuck is statically revolving with the orbit for one revolution (it does not rotate by itself). Practice has proved that the defects of this drying method are: The excess slurry flows down slowly by gravity. Therefore, the resu...

Abstract

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.

Example Embodiment

[0017] Such as figure 1 As shown, the present invention includes a rail 3 (the rail 3 runs in the heating channel 2 in the casing) located in the casing 1 of the powder filling machine and revolving around the center of the casing, and a chuck connected to the rail 3 via a shaft 4, and also includes The operating window 5 provided in the housing 1.
[0018] Such as figure 1 , 2 As shown, the chuck shaft 4 connected to the track 3 has two inner and outer rings, and the shaft 4 of the outer ring chuck is provided with a first transmission wheel 6 and a second transmission wheel 12, and the first transmission wheel 6 is connected to each other through a transmission belt 9 The driving wheel 7 is connected for transmission, and the second transmission wheel 12 meshes with the third transmission wheel 13 on the inner ring shaft for transmission. The shaft 4 of the chuck is rotationally connected to the track 3 (the rotational connection may be a bearing connection or a shaft sleeve connection, and a bearing connection is adopted in this embodiment). The axle of the driving wheel 7 is movably connected to the upper end of the housing 1 (shown in the figure).
[0019] Still as figure 1 As shown, the driving wheel 7 is arranged outside the track 3 at the operating window 5, and a power input wheel 10 is provided on the axle of the driving wheel 7 which is linked with the power output wheel 11.
[0020] Still as figure 1 As shown, a guide wheel 8 of the transmission belt 9 is provided on one side of the driving wheel 7 (as can be seen from the figure, the guide wheel 8 presses the transmission belt to the track so that it meshes with the transmission wheel on the chuck shaft again). The axle of the guide wheel 8 is fixedly connected to the housing 1, and the length of the connection between the guide wheel 8 and the center of the track 3 is less than the length of the connection between the driving wheel 7 and the center of the track 3.
[0021] In this embodiment, the transmission belt 9 is a chain.
