[technical field]
The utility model relates to a kind of coating device of electricity-saving lamp, the rapid draing solidification equipment of the quantitative coating process of particularly a kind of full spiral type class fluorescent tube.
[background technology]
Helical type lamp is divided into the semispiral type structure by structure, full spiral-shaped structure and half full spiral-shaped structure, and shown in Fig. 1 a and 1b, the shape of glass tube two mouths of pipe of semispiral type structure fluorescent tube is the straight glass tube shape, and the axis of two mouths of pipe and fluorescent tube parallel axes; As shown in Figure 2, glass tube two orifice configuration of full spiral-shaped structure fluorescent tube are helical forms, and its axis is the helix of fluorescent tube; Shown in Fig. 3 a and Fig. 3 b, the shape of glass tube two mouths of pipe of half full spiral-shaped structure fluorescent tube is the straight glass tube shape, and from helix to fluorescent tube axis invagination certain angle, the space angle of its axis and fluorescent tube axis is less than 90 degree, and greater than 0 degree, full spiral-shaped structure and half full spiral-shaped structure fluorescent tube are generally called full spiral type class fluorescent tube.
The at present complete quantitative coating process of spiral type class fluorescent tube is: the gyroaxis of tube clamper fluorescent tube folded with it be totally one axis, and tube clamper fluorescent tube folded with it can be done forward and reverse rotation around this axis, the axis of fluorescent tube is parallel to the ground or have angle, from the glass tube of fluorescent tube wherein a mouth of pipe inject quantitative powder and starch in the glass tube, rotate fluorescent tube, the interior powder slurry of glass tube of fluorescent tube is flowed to fluorescent tube whippletree top along passage, the powder slurry arrives backward rotation fluorescent tube behind the fluorescent tube whippletree top, the interior powder slurry of glass tube of fluorescent tube is flowed out along passage another mouth of pipe of glass tube to fluorescent tube, continue the backward rotation fluorescent tube then, and the blowing mouth of blowing device is arranged on the glass tube mouth of pipe right opposite of fluorescent tube, to the blowing of glass tube the inside, steam in the glass tube of fluorescent tube is blown out outside the fluorescent tube, simultaneously fluorescent tube is heated, make the water evaporates of fluorescent material powder slurry of the glass tube inner surface of fluorescent tube, till the bisque that the inner surface of the glass tube of fluorescent tube applies is dried to curing.
Shown in Fig. 2 a, at present in the dry solidification process of full spiral type class fluorescent tube 1 ' coating process, usually the blowing mouth 22 ' of blowing device 2 ' is faced the glass tube mouth of pipe 12 ' the direction arrangement of fluorescent tube 1 ', and inside the glass tube mouth of pipe 12 ' of fluorescent tube 1 ', dry, heater 3 ' is placed in the periphery of fluorescent tube 1 '.
Please refer to the coating device of semispiral type fluorescent tube in the prior art again, in the dusting technology of present semispiral type fluorescent tube, it also is the technical scheme that adopts facing to mouth of pipe blowing in pipe of fluorescent tube, when perhaps in pipe, drying from a mouth of pipe in the technical scheme of another mouth of pipe air draught: as Chinese utility model patent 200720183782.2, a kind of semispiral type fluorescent tube power conservation type coating powder of fluorescent lamp device is proposed, shown in Fig. 2 b, it is a blowing device 2 " blowing mouth 22 " from fluorescent tube 1 " and a mouth of pipe 11 " inwardly blowing the time, with an air intake device 3 " and inlet scoop 32 " at another mouth of pipe 12 " technical scheme of carrying out air draught; Chinese invention patent 200510044030.3 for another example, propose a kind of coating process and equipment of semi-spiral fluorescent tube, and it is the technical scheme of the opening of helical lampl alternately being dried with blowing mouth.
In the above-mentioned existing technical scheme,,, will dispel near the powder slurry that flows the mouth of pipe, cause shadow stripe or trace, so blast can only be little if blast is big because the blowing mouth of blowing device is dried to the glass tube the inside towards the glass tube mouth of pipe position of fluorescent tube; When simultaneously fluorescent tube being heated, because the blowing blast is little, it is also few to blow out vapour quantity; If heat, the steam that is evaporated in a large number that produces can't in time be discharged outside the glass tube, the glass tube interior humidity of fluorescent tube is very high, the powder slurry flows easily, the powder that the glass tube mouth of pipe place of fluorescent tube then can occur is starched when also not draining off, other position bisques of the glass tube of fluorescent tube are thin partially or do not have the powder printing opacity, and the bisque dry solidification time is long, cause the mobile generation bisque thickness phenomenon of powder slurry to influence product appearance.Why electricity-saving lamp manufacturing industry that Here it is adopts low temperature, little air quantity at present in dusting, dry solidification technology guarantees the reason of fluorescent tube dusting bisque quality for a long time.Yet, so just can reduce dusting efficient widely, increased cost, in the industry the general notes powder captain degree that uses at 5~10 meters, about 5~8 minutes of the dusting time of each fluorescent tube.Therefore solve the rapid draing solidification equipment of the quantitative coating process of full spiral type class fluorescent tube, to improve dusting efficient, to reduce production costs, improve the bisque quality significant to the electricity-saving lamp industry development.
