Further, in the process of flowing down the flexible glass ribbon 200, since it is not completely solidified, the fluidity thereof can be changed by the regulation and control of the ambient temperature, so that it is cooled and solidified more quickly or slowly, thereby realizing precise thickness adjustment. Specifically, when the ambient temperature is high, the viscosity of the flexible glass ribbon 200 decreases, the fluidity increases, and the flexible glass ribbon 200 cools and solidifies more slowly, and also forms a thicker thickness, and when the ambient temperature is low, the viscosity of the flexible glass ribbon 200 increases, the fluidity decreases, and the flexible glass ribbon 200 cools and solidifies more rapidly, and also forms a thinner thickness. In the invention, the thermal radiation forming device 100 can accurately regulate the environmental temperature of the flexible glass ribbon 200 in a thermal radiation mode, so that the thickness distribution of the flexible glass ribbon 200 can be accurately regulated, and the device is stable and reliable and has high production efficiency.
The thermal radiation forming apparatus 100 includes an air outlet temperature control mechanism (not shown) and a soaking nozzle 110. The soaking nozzle 110 includes a ventilation pipe (not shown) and a soaking plate 113, one end of the ventilation pipe is connected with an air outlet temperature control mechanism, the other end of the ventilation pipe is connected with the soaking plate 113, a return air channel 114 is arranged in the ventilation pipe, the air outlet temperature control mechanism is used for introducing air flow with preset temperature, preset speed and preset flow into the ventilation pipe, so that the air flow flows out through the return air channel 114 under the blocking effect of the soaking plate 113, and the soaking plate 113 is used for forming a temperature field when the air flow passes through so as to perform heat radiation on the formed flexible glass ribbon 200. In this way, by changing the preset temperature of the air flow, the temperature field formed by the soaking plate 113 can be quickly adjusted, so that the environmental temperature of the flexible glass ribbon 200 can be accurately regulated and controlled, and the thickness distribution of the flexible glass ribbon 200 can be accurately adjusted.
Further, the ventilation pipe comprises an outer pipe 111 and an inner pipe 112, wherein the outer pipe 111 is sleeved outside the inner pipe 112, the outer pipe 111 and the inner pipe 112 are arranged at intervals, and a return air channel 114 is formed. One end of the inner tube 112 is connected with an air outlet temperature control mechanism, the other end of the inner tube is arranged at intervals with the soaking plate 113, the soaking plate 113 is connected with one end of the outer tube 111 in a sealing mode, the air outlet temperature control mechanism is used for leading air flow with preset temperature into the inner tube 112 so that the air flow flows out through the air return channel 114 under the blocking effect of the soaking plate 113, and the soaking plate 113 is used for forming a temperature field when the air flow passes through so as to carry out heat radiation on the formed flexible glass ribbon 200.
Further, the soaking plates 113 are arranged in parallel with the flexible glass ribbon 200 at intervals, so that a temperature field formed on the soaking plates 113 can uniformly radiate heat to the flexible glass ribbon 200, and the radiation effect is improved, thereby improving the temperature control precision and the thickness adjustment precision. In this embodiment, the flexible glass ribbon 200 flows downward in a vertical direction, and the soaking plates 113 are disposed on a vertical plane.
Specifically, the distance between the soaking plate 113 and the flexible glass ribbon 200 is 50mm to 180mm, and the reasonable distance between the soaking plate 113 and the flexible glass ribbon 200 can improve the uniformity of heat radiation and ensure the heat radiation effect. If the distance between the soaking plate 113 and the flexible glass ribbon 200 is too small, the heat of the soaking plate 113 can be directly transferred to the flexible glass ribbon 200 through air, and the too fast heat transfer can influence the curing effect of the flexible glass ribbon 200, so that the product quality is influenced, and if the distance between the soaking plate 113 and the flexible glass ribbon 200 is too large, the heat radiation effect of the soaking plate 113 on the flexible glass ribbon 200 is weak, the effect of accurately controlling the temperature cannot be achieved, and the thickness distribution of the flexible glass ribbon 200 cannot be accurately adjusted.
In an alternative embodiment, soaking plate 113 is made of silicon carbide soaking material and has high radiation capability, and can form a stable temperature field under the action of air flow to heat-radiate flexible glass ribbon 200.
The air outlet temperature control mechanism comprises a fan (not shown) and a heat exchanger (not shown). The fan is connected with the inner tube 112 through a heat exchanger, and the fan is used for blowing out air flow outwards, and the heat exchanger is used for exchanging heat to the air flow so that the temperature of the air flow reaches a preset temperature, thereby realizing the function of leading the air flow with the preset temperature into the inner tube 112.
Preferably, the thermal radiation forming apparatus 100 further includes a mounting frame 120. The soaking nozzle 110 is installed on the installation frame 120, the installation frame 120 is used for being arranged on the side surface of the flexible glass ribbon 200, and the installation frame 120 can fix the position of the soaking nozzle 110 so that the soaking nozzle 110 can form a stable temperature field, and therefore uniform heat radiation is carried out on the side surface of the flexible glass ribbon 200.
Further, the number of the soaking nozzles 110 is plural, the soaking nozzles 110 are divided into two groups, the two groups of soaking nozzles 110 are oppositely arranged at two sides of the flexible glass ribbon 200, the soaking nozzles 110 in each group are arranged at intervals in parallel, and the two groups of soaking nozzles 110 act together to simultaneously perform heat radiation on two sides of the flexible glass ribbon 200, so that the same positions on two sides of the flexible glass ribbon 200 are at the same ambient temperature, the uniformity of thickness adjustment of the flexible glass ribbon 200 is ensured, and the product quality is ensured.
It is to be noted that the flexible glass is classified into an equal thickness flexible glass and an unequal thickness flexible glass, and both the equal thickness flexible glass and the unequal thickness flexible glass can be molded by the heat radiation molding apparatus 100. When the thermal radiation forming device 100 is used for forming the equal-thickness flexible glass, the preset temperature of the air flow introduced into the soaking nozzles 110 is the same, and the temperature fields formed by the soaking nozzles 110 are the same, so that equivalent thermal radiation is applied to the flexible glass ribbon 200, the thickness of the flexible glass ribbon 200 is ensured to be equal everywhere, the equal-thickness flexible glass is obtained, and the thickness uniformity of the equal-thickness flexible glass is improved. When the thermal radiation forming device 100 is used for forming the flexible glass with different thickness, the preset temperature of the air flow introduced into the soaking nozzles 110 is different, and the temperature fields formed by the soaking nozzles 110 are different, so that the unequal thermal radiation is applied to the flexible glass ribbon 200, and the thickness of the flexible glass ribbon 200 is different, so that the flexible glass with different thickness is obtained.
In this embodiment, the thermal radiation forming apparatus 100 is used for forming flexible glass with different thickness, the soaking nozzle 110 includes a first soaking nozzle 130 and a second soaking nozzle 140 that are disposed at intervals, and the preset temperature includes a first preset temperature and a second preset temperature. Specifically, the first preset temperature is less than the second preset temperature, and the air outlet temperature control mechanism is configured to introduce an air flow at the first preset temperature into the first soaking nozzle 130 and also to introduce an air flow at the second preset temperature into the second soaking nozzle 140, so that a temperature field formed by the first soaking nozzle 130 is lower than a temperature field formed by the second soaking nozzle 140, and thus a thickness of a portion of the flexible glass ribbon 200 corresponding to the first soaking nozzle 130 is less than a thickness of a portion of the flexible glass ribbon 200 corresponding to the second soaking nozzle 140. In this way, two portions of flexible glass ribbon 200 having different thicknesses are formed as shaped flexible glass ribbon 200 passes through thermal radiation shaping apparatus 100, thereby providing flexible glass of unequal thickness.
However, the present invention is not limited thereto, and in other embodiments, the soaking nozzle 110 may further include a third soaking nozzle, the preset temperature may further include a third preset temperature, the second preset temperature is less than the third preset temperature, the air outlet temperature control mechanism is configured to introduce the air flow of the third preset temperature into the third soaking nozzle, so that the temperature of the temperature field formed by the second soaking nozzle 140 is lower than the temperature field formed by the third soaking nozzle, and thus the thickness of the portion of the flexible glass ribbon 200 corresponding to the second soaking nozzle 140 is smaller than the thickness of the portion of the flexible glass ribbon 200 corresponding to the third soaking nozzle, and further three portions of different thickness of the flexible glass ribbon 200 are formed, in other embodiments, the soaking nozzle 110 may further include a third soaking nozzle and a fourth soaking nozzle, the preset temperature may further include a third preset temperature and a fourth preset temperature, the second preset temperature is less than the third preset temperature, the third preset temperature is less than the fourth preset temperature, and the thermal radiation forming device 100 is capable of forming four portions of different thickness of the flexible glass ribbon 200, and further defining different amounts of air flows into different portions of the soaking nozzle 200.
It should be noted that, due to structural limitation, the temperature of the air flow output by the air outlet temperature control mechanism is within a certain temperature range, that is, the air flow output by the air outlet temperature control mechanism has the highest temperature and the lowest temperature. In the case of a conventional straight barrel soaking nozzle 110, if the air flow output by the air outlet temperature control mechanism has reached the minimum temperature, the thickness of the flexible glass ribbon 200 is still relatively thick (thinner production requirements are not met), and then an improvement in the shape of the soaking nozzle 110 is required. Accordingly, in the case of a conventional straight soaking nozzle 110, if the air flow output from the air outlet temperature control mechanism has reached the maximum temperature, the thickness of the flexible glass ribbon 200 is still relatively thin (no thicker production requirements are met), and the shape of the soaking nozzle 110 needs to be improved. Through adopting the soaking nozzle 110 of multiple shape design in this scheme, can make the temperature regulation of soaking plate 113 on the basis of the air current temperature range of original air-out temperature control mechanism output, further increase the temperature regulation scope breaks the limitation of temperature regulation that original structure restriction brought to increase the temperature range of radiation on flexible glass area 200, make the further improvement of temperature management and control of flexible glass area 200, realize accurate thickness adjustment.
In an alternative embodiment, the first predetermined temperature is lower (near or equal to the minimum temperature) and the first soaking nozzle 130 is tapered to rapidly cool the corresponding location on the flexible glass ribbon 200 and allow it to solidify more rapidly, thereby providing a thinner thickness to meet the manufacturing requirements.
Specifically, in the first soaking nozzle 130, the diameter of the inner pipe 112 gradually decreases in the air intake direction, and the diameter of the outer pipe 111 gradually increases in the air return direction, i.e., the shape of the outer pipe 111 matches the shape of the inner pipe 112, and the sectional area of the air return passage 114 is equal everywhere in the air return direction. In this way, when the air outlet temperature control mechanism outputs air, the air flow with the first preset temperature flows in the inner tube 112 towards the direction close to the soaking plate 113, in this process, the diameter of the inner tube 112 is gradually reduced, the cross-sectional area of the inner tube 112 is also gradually reduced, so that the air flow speed is increased, the pressure is reduced (according to the bernoulli principle, the air flow speed is higher, the pressure is smaller), so that the air flow can be blown to the soaking plate 113 quickly, the heat of the soaking plate 113 is taken away quickly, the flexible glass ribbon 200 is cooled quickly, the solidification speed is accelerated, the thickness is reduced, and then the air flow with the heat of the soaking plate 113 flows out through the air return channel 114. In this way, the tapered first soaking nozzle 130 enables the formation of a thinner flexible glass ribbon 200 than a conventional straight soaking nozzle 110 to meet production requirements.
In the first soaking nozzle 130, the inner tube 112 includes a first straight section 1121, a reduced mouth section 1122, and a second straight section 1123, which are connected in sequence. The necking section 1122 is disposed between the first straight section 1121 and the second straight section 1123, and in this embodiment, the first straight section 1121, the necking section 1122 and the second straight section 1123 are integrally formed to improve the connection strength. Specifically, the first straight section 1121 is disposed coaxially with the second straight section 1123, the diameter of the first straight section 1121 being larger than the diameter of the second straight section 1123, i.e., the small end of the necked-down section 1122 is connected to the second straight section 1123, and the large end of the necked-down section 1122 is connected to the first straight section 1121. The first straight section 1121 is connected with an air outlet temperature control mechanism, the second straight section 1123 is arranged at intervals with the soaking plate 113, the air outlet temperature control mechanism can introduce air flow with a first preset temperature into the first straight section 1121, the air flow speed is increased under the action of the necking section 1122, the pressure is reduced, the air flow continuously flows into the second straight section 1123, the air flow passing through the second straight section 1123 is quickly blown to the soaking plate 113, and flows back through the return air channel 114 under the blocking action of the soaking plate 113, in the process, the soaking plate 113 forms a temperature field with a lower temperature under the action of the air flow with the first preset temperature, so that the flexible glass ribbon 200 is quickly cooled, the solidification speed is accelerated, and the thickness is formed to be thinner.
In this embodiment, in the first soaking nozzle 130, the necking section 1122 is arranged in a straight line, and the necking section 1122 arranged in a straight line can stably guide the airflow when the airflow passes through, so that the flow velocity of the airflow is uniformly increased, the occurrence of turbulent flow is avoided, and the temperature uniformity of the soaking plate 113 is ensured. However, in other embodiments, the necking sections 1122 may be arranged in an arc shape, and the air flow can be stably guided, so that the temperature uniformity of the soaking plate 113 is ensured, and the shape of the necking sections 1122 is not particularly limited.
In an alternative embodiment, the second soaking nozzle 140 is tapered and then gradually expanded to keep the temperature or heat the corresponding position on the flexible glass ribbon 200, so that the position is cured more slowly, and a thicker thickness is formed to meet the production requirement.
Specifically, in the second soaking nozzle 140, the diameter of the inner pipe 112 decreases and then increases in the air intake direction, and the diameter of the outer pipe 111 decreases and then increases in the air return direction, that is, the shape of the outer pipe 111 matches the shape of the inner pipe 112, and the cross-sectional area of the air return passage 114 is equal everywhere in the air return direction.
