Abstract
The invention relates to a method for controlling a glass cooling process during glass toughening. The method for controlling the glass cooling process during glass toughening has the advantages that a previous mode that cooling time is judged according to experience of operating workers is changed, and temperature sensors are set to be used for detecting temperature of glass in a glass toughening air-cooling section; when the temperature of the glass in the air-cooling section reaches or is approximate to the set temperature, a control center gives an instruction to a controller of a transmission mechanism to move the glass to a next process step, or the control center gives an instruction to a fan controller to decrease fan frequency to continue air cooling, so that dependency on the skilled workers during glass toughening is lowered; when glass toughening is completed, the fan frequency is decreased timely or the glass is moved to the next process step, so that on one hand, extra energy consumption caused by the fact that glass toughening is already completed but the glass is still under high air pressure is avoided, and on the other hand, the obtained toughened glass is high in product qualified rate and stable in product quality.
Description
Technical field
The present invention relates to glass fibre reinforced plastic equipment technical field, be specifically related to a kind of method controlling glass cools process in glass tempering process.
Background technology
The physical toughened mode of glass needs to treat that toughened glass is heated to close to softening temperature in annealing furnace, and then cooling has carried out the tempering of glass rapidly, also needs to continue cooling until glass is cooled near room temperature after tempering completes.Usually only in the process of cooling formation stress and shaping rapidly, use greater pressure, and in follow-up cooling down, only use less blast to reduce energy consumption.Traditional glass fibre reinforced plastic equipment is all use to estimate duration to control the conversion of glass size blast in cooling process or the time point terminated that is shaped, and cooling end time point.But because the kind of glass is different, color error that is different, its thickness is also different, add envrionment temperature difference, by aforesaid method we can not size blast point switching time, be shaped the end time point and cooling the end time point calculate so accurate, need operator to sum up in practice, but the experience depending on operator unduly can affect the qualification rate of product and the stability of quality or energy consumption.

The object of the invention is the deficiency for solving the problems of the technologies described above, a kind of method controlling glass cools process in glass tempering process is provided, the temperature of glass in air-cooled section is detected by set temperature sensor, when the temperature of glass in air-cooled section reach or close to setting temperature time, control center provides instruction to actuator controller, glass sliding is provided instruction to controller of fan to next operation or control center, reduces blower fan frequency and continue air-cooled.
The present invention is the deficiency solved the problems of the technologies described above, the technical scheme adopted is: a kind of method controlling glass cools process in glass tempering process, the glass shifted out from glass tempering furnace heating zone cools at air-cooled section, at least one is set in air-cooled section of glass tempering furnace for detecting the temperature sensor of glass temperature in air-cooled section, temperature sensor is connected with control center, control center is also connected with the actuator controller of air-cooled section and controller of fan, before glass cools, treat that toughened glass sets the temperature treating that the cooling of toughened glass needs arrives in advance according to different, when the temperature of glass reach or temperature close to setting time, two kinds of operating method can be had: first, control center provides instruction to actuator controller, by glass sliding to next operation, the second, control center provides instruction to controller of fan, reduces blower fan frequency and continues air-cooled.
Said temperature sensor is thermocouple temperature sensor, thermal resistance temperature sensor or infrared temperature sensor.As preferred version of the present invention, described temperature sensor is provided with 2-6.As most preferably scheme of the present invention, described temperature sensor is provided with 2-4.
The position of temperature sensor arranges as follows: the first situation: temperature sensor is all arranged on above the live rollers of glass tempering furnace; The second situation: temperature sensor is all arranged on below the live rollers of glass tempering furnace; The third situation: be at least provided with a temperature sensor respectively above and below the live rollers of glass tempering furnace.
beneficial effect
Method of the present invention is for controlling the cooling time of glass in glass tempering process, change in the past by operator in the mode of micro-judgment cooling time, the temperature of glass in air-cooled section is detected by set temperature sensor, when the temperature of glass in air-cooled section reach or close to setting temperature time, control center provides instruction to actuator controller, glass sliding is provided instruction to controller of fan to next operation or control center, reducing blower fan frequency continues air-cooled, reduce the dependence to skilled labor in glass tempering process, when glass completes tempering, the frequency of timely reduction blower fan or by glass sliding to next operation, avoid on the one hand glass tempering complete but still carry out high blast thus cause extra energy consumption, also make on the other hand the toughened glass conforming product rate that obtains high and constant product quality.
