U-shaped lamp tube powder coating device

Abstract

The invention discloses a U-shaped lamp tube powder coating device, which comprises a reciprocating conveying table, basket feeding mechanisms are arranged over the left end and the right end of the reciprocating conveying table respectively, any basket feeding mechanism is provided with a lamp tube feeding basket in a matched mode, and a plurality of U-shaped lamp tubes are arranged in the lamp tube feeding basket in an array mode. A powder injection mechanism is arranged between the two basket feeding mechanisms, a conveying frame is correspondingly arranged on the reciprocating conveying table below the powder injection mechanism, another conveying frame is correspondingly arranged on the reciprocating conveying table below one basket feeding mechanism, the two conveying frames are fixedly connected through a connecting rod, and the two conveying frames are both matched with the lamp tube feeding basket; basket pushing mechanisms matched with the basket feeding mechanisms at the corresponding ends are arranged on the front sides of the left end and the right end of the reciprocating conveying table, and basket turning mechanisms matched with the basket pushing mechanisms at thecorresponding ends and the lamp tube feeding baskets are arranged on the rear sides of the left end and the right end of the reciprocating conveying table; the problems that the U-shaped fluorescent lamp tube cannot be coated with powder in batches, the powder coating efficiency is low, and the labor cost is increased are effectively solved.

Description

technical field [0001] The invention belongs to the field of processing equipment for fluorescent lamp tubes, in particular to a U-shaped lamp tube powder coating device. Background technique [0002] The principle of the fluorescent tube is: the tube is filled with argon gas with a pressure of 400Pa-500Pa and a small amount of mercury. After electrification, liquid mercury evaporates into mercury vapor with a pressure of 0.8Pa. Under the action of an electric field, the mercury atoms are continuously excited from the original state to the excited state, and then spontaneously transition to the ground state, and radiate ultraviolet rays with wavelengths of 253.7nm and 185nm (the main peak wavelength is 253.7nm, accounting for about 70-80% of the total radiant energy. %; the second peak wavelength is 185nm, accounting for about 10% of the total radiant energy), to release excess energy. Phosphor powder absorbs the radiant energy of ultraviolet light and emits visible light....
