With known technology relatively, this technology invention can make single curved Glass tubing inwall, application of suspension onto equably.
Longitudinal axes is to be made by the straight section of single curved glass tube.With regard to this invention, the axial rotation of single curved glass tube is meant around the axis rotation parallel with the single glass tube straight section, is meant the rotation of doing around by the axis of single glass tube turning point especially.
If in the process of oven dry suspension, single curved glass tube is in vertical stationary state, and is then ideal.
This invention also comprises that the mouth of pipe is downward when entering drying channel with the reversing of the single curved glass tube behind the application of suspension onto, and unnecessary suspension can drip down, and suspension can be dry equably.The drying of suspension can be from the curved position of the U type at single curved glass tube top.
Suspension if can be then better with hot dry-air blast or thermal radiation oven dry.
In coating process, as suspension can flow several times be then better back and forth in single curved glass tube, preferably two to four times.
For achieving the above object, according to the invention provides a kind of is application of suspension onto inner wall of single curved glass tube or the technology of coating luminophore suspension, after one of them mouth of pipe injects quantitative suspension, single glass tube is when pivoting commentaries on classics, also make level and wallowing motion, the pipe arm of single glass tube remains on level attitude between the reverse point that tilts to rotate, the single glass tube mouth of pipe is dried downwards then.
In the process of oven dry suspension, single glass tube remains on vertical stationary state.Single glass tube is behind application of suspension onto, and the mouth of pipe enters drying stroke downwards, allows unnecessary hanging drop walk, and makes suspension be dried equably.The dry curved position beginning of U type by the single glass tube top.Drying is to carry out with hot blast or thermal radiation.In coating process, suspension flow several times back and forth in single glass tube preferably has two to four times.The quantitative suspension of being injected just in time is the needed deal of coating.Be the single glass tube application of suspension onto of caliber above 8 millimeters.
The quantitative suspension of injecting a mouth of pipe of single curved glass tube preferably just enough is coated with application.
This invention also is included as the single curved glass tube of caliber above 8 millimeters and applies.
The invention of this technology, the application of suspension onto inner wall of single curved glass tube ideally is to be used as the discharge tube of miniature lamp.Used suspension is luminophore suspension.
The equipment that this coated technique is required comprises chain transfer, Glass tubing base, swivel arrangement, feeding metering device and drying channel.According to this invention, each Glass tubing base couples together with articulated joint and cam plate, can be for vertical movement, and base equidistantly is distributed on the endless chain.Swivel arrangement is contained in the drying channel front, so that wallowing motion is made simultaneously in glass header reverse rotation one by one again.
Swivel arrangement and chain transmission system parallel rotation.The plane at swivel arrangement place is made by chain transmission system.According to this invention, the Glass tubing base is so that the swing of Glass tubing, is that the connection drive disk assembly by cam plate and swivel arrangement orders about.Therefore, the speed of rotation of Glass tubing base and direction are that the speed of relative movement by chain transmission system and swivel arrangement decides.
