Abstract
The invention discloses a machine for baking a cold cathode lamp tube. The machine comprises a baking oven and a conveyer in the baking oven. An upward convex cavity is arranged at the top of the baking oven, a radiant panel is arranged at the top of the convex cavity, and heating devices are arranged at one side or opposite sides of the convex cavity. The conveyer inclines in a direction from a powder tube entry to a powder tube exit, and a horizontal included angle is at least 5 degrees. A powder tube arranged on the conveyer is provided with a sleeve. When the machine for baking the cold cathode lamp tube is used for heating the powder tube, convection, conduction heating and radiation heating exist, and the utilization rate of heat energy is high; in addition, the powder tube is provided with the sleeve, and the powder tube and the sleeve are in a rolling state during heating, thus the powder tube is heated more uniformly, oxidation, decomposition and release of a bonder in a fluorescent powder layer are facilitated, and the quality of the powder tube is ensured.
Description
Technical field
The present invention relates to the electric light source products preparation field, be specifically related to the roasted tube equipment of cold cathode fluorescent lamp.
Background technology
Coat the cold cathode fluorescent lamp of powder, be referred to as tube cell, must with the binding agent in its phosphor powder layer (being generally polyethylene glycol oxide) oxidation, decompose, disengage through high-temperature baking.The temperature of roasted tube is about 500 ℃.
Present tube-baking machine nearly all is the tunnel type tube-baking machine, in the tunnel type baking oven heater is installed, send into different humidity provinces by the tube cell that metal belt will be to be baked, maximum temperature is about 500 ℃, also is provided with blower system in the baking oven, dries in tube cell in good time, the steam that binding agent discharges when blowing away heating on the one hand, blast fresh air simultaneously, quicken the oxidation of binding agent, thereby eliminate binding agent.
Heater in the baking oven generally has electric heating or coal gas heating, no matter be electric heating or coal gas heating, heater generally all is arranged on the below or the both sides of metal belt, heat transmission has only convection current, conduction dual mode, tube cell is in heating process in addition, and remain static (self being not move), therefore, this roasted tube mode, the defective of existence is: the heat efficiency is low, the roasted tube quality can not get guaranteeing.
Simultaneously, tube cell to be sent in the tunnel baking oven, metal belt and part drive system thereof must pass in and out baking oven, and how long conveyer belt advances in baking oven, will advance equally outside baking oven the so long time, that is to say, conveyer belt is warmed to 500 ℃ in baking oven, be cooled to room temperature outside baking oven again, is constantly circulating, consumed a large amount of heats, also thermal pollution has been caused in the production scene.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of cold cathode fluorescent lamp tube-baking machine, and heat transmission not only has convection current, conduction, also has radiation, simultaneously, tube cell is kept in motion in heating process, and the conveyer of tube cell is only worked in baking oven, heat transfer efficiency height, the saving energy.
The present invention is achieved through the following technical solutions:
A kind of cold cathode fluorescent lamp tube-baking machine comprises baking oven, the conveyer in the baking oven, and the top of described baking oven is provided with protruding chamber upwards, and protruding top of chamber is provided with radiant panel, and heater is arranged at protruding chamber one side or opposite side.
The further improvement project of the present invention is that to the inclination of tube cell Way out, vertical angle is at least 5 degree to the conveyer in the baking oven from the tube cell inlet.The rolling of sleeve pipe on roller-way of tube cell is housed, the one, the roller turn in roller rest road makes the sleeve pipe Way out, and the 2nd, be that the gradient that roller-way is provided with is rolled to outlet roller by conveyer.
The present invention further improvement project is that described conveyer is a roller-way.Each roller two ends in the described roller-way are movably connected on baking oven, and the roller end is provided with drive, and the output wheel by driving-belt and power set links transmission.
The present invention further improvement project is that the tube cell that is positioned on the conveyer is provided with sleeve pipe.Described sleeve pipe is the light-wall pipe of metal material, and two tube cells are housed in every branch casing at least.
The present invention compared with prior art has following obvious advantage:
One, the present invention is owing to be provided with protruding chamber at the top of baking oven, and the top in protruding chamber is provided with radiant panel, and protruding chamber one side or opposite side are provided with heater, and therefore, when heat to tube cell, existing convection current, conduction are heated, and radiation heating are more arranged, heat energy utilization rate height.
Two, the present invention is owing to metal belt is set to tilt to the tube cell Way out from the tube cell inlet, vertical angle is at least 5 degree, therefore, is placed on the tube cell on the conveyer, in heating process,, all faces of tube cell are heated evenly always rolling to Way out.
Three, the present invention more one goes on foot in the improvement project, be contained in tube cell in the sleeve pipe and then be positioned on the conveyer, can prevent that first tube cell phase mutual friction in rolling process from causing damage, second the tube cell that is contained in the sleeve pipe conducts heat mutually, sleeve pipe accumulation of heat (temperature in the sleeve pipe is constant relatively) is arranged outside adding, the rolling of sleeve pipe and the rotation of the interior tube cell of pipe are more arranged, it is more even that tube cell is heated, be more conducive to the binding agent in the phosphor powder layer oxidation, decompose, disengage, guarantee the quality of tube cell.
Four, the present invention is improved to roller-way with conveyer belt of the prior art, and roller-way is arranged in the baking oven, has overcome the energy loss that the conveyer belt turnover baking oven of prior art brings, and the thermal pollution that causes to operating environment.
