Description
[technical field]
The utility model relates to a kind of manufacturing equipment of compact fluorescent lamp, particularly a kind of compact fluorescent lamp strip tube baking device.
[background technology]
Industry is known: the roasted tube purpose of compact fluorescent lamp is that the binding agent in the fluorescent material is dried only, its roasted tube process is, fluorescent tube after the dusting is admitted to tube-baking machine, binding agent in the fluorescent material bisque in the fluorescent tube is under the temperature of roasted tube, resolve into gases such as carbon monoxide and carbon dioxide, the blowing device of tube-baking machine is aimed at the fluorescent tube mouth of pipe towards the inner blowing of fluorescent tube, in the fluorescent tube carbon monoxide and gas such as carbon dioxide blow out outside the fluorescent tube, till binder decomposed in bisque is clean, if when binder decomposed does not thoroughly reach things such as containing hydrogen sulfide in the roasted tube atmosphere and other hydrocarbons, will directly influence the luminous flux and the lux maintenance of fluorescent tube.
Two kinds of technical schemes of the main employing of roasted tube technology in the industry and device thereof at present: first kind, a default both ends open and fixed baking oven, some mouth of blast pipes of blowing device are fixed on the baking oven, one chain-type that is mounted with tube clamper and fluorescent tube air duct loops back to transfer and send device to pass through baking oven, be mounted with compact fluorescent lamp strip on this tube clamper, fluorescent tube loops back to transfer by the chain-type of doing continuously or move intermittence and send device to send the baking oven heating to, the blowing roasted tube is behind the roasting good fluorescent tube, fluorescent tube loops back to transfer with the chain-type of doing continuously or move intermittence and send device to leave baking oven; Second kind, default fixed baking oven, the blower of blowing device is installed on the body of heater, a roasted tube rack device that has air duct of forming by several tube clampers, in the baking oven outside, fluorescent tube is placed on the tube clamper of roasted tube rack device, push baking oven then, shut behind the fire door baking oven heat up heating, blowing roasted tube, behind the roasting good fluorescent tube, the baking oven cooling is opened fire door and is withdrawed from the roasted tube rack device after the cooling.
Mainly there are following shortcoming in above-mentioned technology and device thereof: first kind of technical scheme: 1, because the looping back to transfer and send device to pass through baking oven of chain-type, make two of baking oven must opening, heat insulating ability be poor; 2, chain conveyor turnover baking oven can be taken away many heats; 3, blowing device wind blows into baking oven formation heat convection current, and heat runs off easily in the baking oven poor sealing baking oven; 4, because looping back of chain-type transfers that to send device be flexible conveying device, the position of the air duct of the tube clamper on it and the blowing mouth of blowing device is difficult for accurately, and the blowing effect is subjected to the manufacturing, influence of mounting accuracy of auto levelizer and influences the roasted tube quality of fluorescent tube; 5, the wind of blowing device is difficult for heating, and the temperature that is blown into the wind in the fluorescent tube is more much lower than the temperature that roasted tube requires, and blowing each time all makes the glass tube internal temperature of fluorescent tube reduce, and influences the efficiency of heating surface; Second kind of technical scheme: 1, can't realize continuous roasted tube, roasted tube efficient is low, 2, each time periodically in the roasted tube process, when each roasted tube finishes to take out fluorescent tube, carry out after need opening the baking oven cooling, and the time pause longlyer, baking oven is owing to repeat to heat up, temperature-fall period and cause waste of energy big.
The electricity-saving lamp baking machine that is disclosed as Chinese patent application 200610166323.3 and Chinese utility model patent 200620073800.7, and the tube-baking machine of the blowing at intermittence of Chinese utility model patent 200720108142.5 announcements, all there is above-mentioned the same technical disadvantages.Present as can be seen roasted tube technology and device thereof have expended a large amount of energy, and the fluorescent tube quality conformance of being produced is relatively poor.Therefore how to solve the steady quality of the problem of above-mentioned existence to compact fluorescent lamp tube, the cost that reduces fluorescent tube is significant.
