Fluorescent baking machine drying shaft

Abstract

The present invention provides a fluorescent baking machine drying shaft. The shaft rod outer end head of the drying shaft and a ceramic shaft are connected and fixed through a metal sleeve. The metal sleeve is provided with a screw clamp which fastens a ceramic shaft, and a fastening card is arranged between a shaft rod and the ceramic shaft. Through connecting the shaft rod and the ceramic shaft by the metal sleeve, the characteristic of reducing thermal energy loss of the ceramic shaft is maintained, and the phenomenon of a loss caused by accidental breakage can be avoided through the metal sleeve.

Description

technical field [0001] The invention relates to a roasting machine component used in producing fluorescent lamps, in particular to a drying shaft of a fluorescent lamp roasting machine. Background technique [0002] In the process of producing fluorescent lamps, a baking machine is used to bake the tube body. The traditional equipment uses a stainless steel rotating shaft to bake in rotation, but since stainless steel is a metal heat-conducting material, the equipment will be baked during the baking process. The internal heat transfers to the outside and causes heat loss. In the equipment transformation in recent years, equipment manufacturers use ceramic shafts for metal shafts to avoid heat loss. The use of such ceramic shafts greatly reduces heat loss, but in In actual use, the shaft head at the transmission end of the ceramic shaft is very easy to cause accidental breakage during uninterrupted rotation, which directly affects the normal production.
