Description
Technical field
The present invention relates to glass manufacturing apparatus, especially a kind of glass lens annealing device.
Background technology
Temperature reachable more than one thousand of the high borosilicate lens when rigid molding is come out of the stove is spent, due to the principle of rising-heat contracting-cold, rapidly
Cooling can influence the rupture of glass lens itself.Traditional technique is annealed with annealing device, due to annealing device
Temperature does not reach appropraite condition, and still there are fracture phenomenas for product.
Invention content
Technical problem to be solved by the invention is to provide a kind of glass lens annealing devices, can be segmented gradual annealing,
Reduce product rupture rate.
In order to solve the above technical problems, the technical solution adopted in the present invention is：
A kind of glass lens annealing device, including annealing furnace and leer；The annealing furnace includes thermal insulation furnace body, in thermal insulation furnace body
It equipped with heat preservation conveyer belt, keeps the temperature and positioning mould is installed on conveyer belt, positioning mould is adapted with glass bar shape, above heat preservation conveyer belt
It is in series with multiple U-shaped heating tubes；The leer includes annealing furnace body, and annealing conveyer belt, annealing transmission are equipped in annealing furnace body
Band top is parallel with Elema heating unit, lower section is equipped with multiple air cooling equipments；Along length side in the annealing furnace and leer
To multiple thermocouples are evenly equipped with, thermocouple is connect with external temperature control device, U-shaped heating tube, Elema heating unit and external electrical
Source connects.
The annealing furnace and leer right angle setting, and outlet of still of annealing is tilted to leer import direction.
It is equipped with high temperature resistant cushion on changeover portion in the positioning mould, between annealing furnace and leer.
The air cooling equipment is electric fan.
Spacing distance is gradually increased by direction of transfer between the Elema heating unit.
The annealing conveyer belt is tensioned by tensioning apparatus.
A kind of glass lens annealing device of the present invention, has the following technical effects：
1）, due to high borosilicate lens need from more than 1,000 degree gradually cooling be annealed to room temperature, this need a progressive formation, pass through
Annealing furnace is set, using concatenated U-shaped heating tube heating and thermal insulation, carries out slow cooling, avoids bust and generate and expand with heat and contract with cold
Cause to rupture, be entered in leer after appropriate annealing, carries out degression type heating using Elema and electric fan is coordinated to carry out
Heat dissipation, ensures that annealing temperature continuously decreases.1.2 meters wide due to 11 meters of slow cooling furnace superintendent, length is longer to be carried out slowly being segmented drop
Temperature, wider width can continuously be put into the glass lens stick of sufficient amount, meet actual needs.
2）, due to glass bar rupture it is smaller, it is also safer in process, reduce cutting or polishing etc. processes it is unexpected
Fragmentation is hurted sb.'s feelings.
Description of the drawings
The invention will be further described with reference to the accompanying drawings and examples：
Fig. 1 is the front view of the present invention.
Fig. 2 is the vertical view of the present invention.
Fig. 3 is the sectional view of positioning mould in the present invention.
In figure：Annealing furnace 1, leer 2, thermal insulation furnace body 3, conveyer belt 4, positioning mould 5, heating tube 6, furnace body 7 of annealing, annealing
Conveyer belt 8, Elema heating unit 9, air cooling equipment 10, thermocouple 11, tensioning apparatus 12.
Specific implementation mode
As shown in Figs. 1-3, a kind of glass lens annealing device, including annealing furnace 1 and leer 2；The annealing furnace 1 includes
Thermal insulation furnace body 3, is equipped with heat preservation conveyer belt 4 in thermal insulation furnace body 3, and heat preservation conveyer belt 4 is chain drive, and array, which is equipped with, on chain drive determines
Position mould 5, slides into after glass bar is molded for the first time in positioning mould 5, carries out positioning and is fed forward.Keep the temperature 4 top series connection of conveyer belt
There are multiple U-shaped heating tubes 6, U-shaped heating tube 6 is uniformly distributed along its length, is fixed by aluminium foil bolt etc., and upper end is stretched out
Annealing furnace 1 is outer to be connect with external power, after being heated to suitable annealing temperature, the high-boron-silicon glass stick that can be spent to more than 1,000 into
Row slowly annealing；The leer 2 includes annealing furnace body 7, and annealing conveyer belt 8 is equipped in annealing furnace body 7, and annealing conveyer belt 8 is adopted
With iron net band, 8 top of annealing conveyer belt is parallel with Elema heating unit 9, lower section is equipped with multiple air cooling equipments 10.Wherein, silicon
Carbon-point heating unit 9 is made of three concatenated Elemas, and air cooling equipment 10 uses electric fan.Elema heating in parallel is single
Member 9 can be turned off or be closed according to actual needs, had preferable independence, can be carried out silicon-carbon according to the temperature in somewhere in this way
The heating or disconnection of stick heating unit 9 ensure that entire annealing section is annealed according to required temperature, more convenient in control.
Since glass bar temperature has been reduced to several Baidu at this time, by the way that Elema heating is arranged above, lower section is arranged fan and carries out
Heat transfer, helps speed up heat transfer, and temperature uniformity is higher.
In order to be monitored to the temperature in annealing furnace 1 and leer 2, it can be respectively mounted thermocouple 11 in two furnace bodies,
The temperature information detected is passed to temperature control modules, such as one-chip computer module by thermocouple 11, when temperature is except setting value
When, temperature control modules are turned off or are closed to the relay switch on heater circuit, to realize U-shaped heating tube 6, silicon-carbon
Stick heating unit 9 is powered or power-off, to realize the control of temperature, ensures that the temperature of each point reaches necessary requirement.
2 right angle setting of the annealing furnace 1 and leer, and annealing furnace 1 is exported and is tilted to 2 import direction of leer.In this way
It can be by gravity automatically into next annealing operation, without consuming excess power after carrying out first segment process annealing.
It is equipped with high temperature resistant cushion on changeover portion in the positioning mould 5, between annealing furnace 1 and leer 2.Thus it can keep away
Exempt from transfer and hits scratch glass bar.
Spacing distance is gradually increased by direction of transfer between the Elema heating unit 9.As annealing temperature reduces, lead to
The reasonable Arrangement on position is crossed, heating temperature can be made to continuously decrease, meets annealing and requires, reduces the cumbersome adjusting of the upper transition of control.
The annealing conveyer belt 8 is tensioned by tensioning apparatus 12.Tensioning apparatus 12 includes tightener sprocket, tightener sprocket
It is mounted on by screw rod in the rack of leer.The chain of annealing conveyer belt 8 bypasses tightener sprocket, is suitably adjusted by screw rod
Tightener sprocket stretches out retraction and carries out elastic adjusting to chain.
