Embodiment Construction

[0026] The inventor first studied the existing powder coating method, and found that the existing method of static drying of the spiral lamp tube cannot make the powder slurry at the bottom of each circle of the spiral lamp tube flow out during the coating process of the fluorescent powder slurry , so that the powder slurry is deposited in the lamp tube and adheres to the bottom of the tube wall, resulting in black shadow phenomenon.

[0027] Therefore, in order to effectively solve the black shadow phenomenon caused by the powder coating of the spiral lamp tube, the inventor has innovated the powder coating method of the spiral lamp tube, and invented the horizontal water-based roller coating method for powder coating; this powder coating method is carried out sequentially according to the following steps :

[0028] 1. Phosphor powder slurry injected into the lamp tube

[0029] Inject the well-proportioned phosphor powder slurry into the clean and dry spiral lamp tube after ...

Abstract

This invention involves a screw fluorescent lamp tube to roll the type to spread the powder method and the equipment. The goalies provides spreads the powder method and the equipment ought to beagle effectively to eliminate the spiral lamp tube endophragm the luminous powder shadow, has the lamp tube light effect high, spreads the powder to be even, the economical material characteristic. The technical plan is: The spiral fluorescent lamp tube rolls the type to spread the powder method, according to following step succession: 1.The luminous powder wheat-flour paste pours into the lamp tube; 2.Pours the excessive luminous powder wheat-flour paste; 3. Carries onto the spiral lamp tube rolls spreads; Inclines the certain angle the spiral lamp tube, and causes it to be at the rotational state; Fourth, the wheat-flour paste stereotypic is dry. The spiral lamp tube rolls spreads the equipment, including a disc as well as in the disc border certain rotations organization, each rotation organization stretches out hold-down bars, in order to spiral lamp tube spatial wrap and localization; The hold-down bars spool thread and the horizontal plane angle for 0-30degree, each rotation organization under meets the powder trough. Each rotation organization above also is equipped with as soon as blows the gusty area, carries on dryly catches a chill.

Description

technical field [0001] The invention relates to a powder coating method and equipment for fluorescent lamp tubes, in particular to a rolling powder coating method and equipment for spiral fluorescent lamp tubes. Background technique [0002] Because the spiral energy-saving lamp has many advantages such as high luminous efficiency and energy saving, it has been widely promoted and applied at present. However, there will be phosphor black shadows at the bottom of each circle of the inner wall of the current spiral lamp tube. The main reason is that the powder slurry at the bottom of the inner wall of the lamp tube is too thick, resulting in the area at the bottom of the lamp tube not being able to emit light, which not only reduces the brightness of the lamp tube. Luminous efficiency, a waste of fluorescent powder, also affects the overall aesthetics of the lamp. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiency of the ab...
