Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of liquid crystal glass, in particular to a heat radiation air duct for online adjustment of the thickness of liquid crystal glass. Background Art
[0002] The thermal radiation duct for online adjustment of the thickness of the liquid crystal glass is a device for heating the liquid crystal glass. The glass is heated by thermal radiation, thereby adjusting the thickness of the glass.
[0003] During the glass overflow and pull-down process, when the glass leaves the tip of the overflow brick, the glass enters the thinning area. In actual use, the thickness of the glass is mostly fine-tuned by adjusting the air flow and air temperature.
[0004] During the glass overflow and pull-down process, the middle part of the glass plate will be subjected to greater tensile force, while the edge part will be subjected to smaller tensile force. At the edge part of the glass plate, due to the smaller tensile force, the effect of adjusting the air flow and air temperature on the glass thickness is also smaller, so the adjustment amount is limited. This results in the position for fine-tuning the glass thickness being limited to the middle part of the glass plate. Utility Model Content
[0005] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a heat radiation air duct for adjusting the thickness of liquid crystal glass online, which solves the problem that in the process of glass overflow and pull-down, the middle part of the glass plate is subjected to a greater tensile force, while the edge part is subjected to a smaller tensile force. At the edge part of the glass plate, due to the smaller tensile force, the effect of adjusting the air flow and air temperature on the glass thickness is also smaller, so the adjustment amount is limited, which leads to the problem that the position for fine-tuning the glass thickness is limited to the middle part of the glass plate.
[0006] To achieve the above-mentioned purpose, the utility model proposes a heat radiation duct for online adjusting the thickness of liquid crystal glass, comprising: a storage shell, a glass plate, connectors are symmetrically fixedly arranged on both sides of the glass plate, the length of the connector is greater than the length of the glass plate, a plurality of heat radiation ducts are inserted inside the connector, a heating wire is arranged inside the heat radiation duct, a high-temperature resistant wire is welded to one end of the heating wire, and a power regulator is connected to the end of the high-temperature resistant wire away from the heating wire.
[0007] As a further solution of the utility model: a U-shaped overflow groove is opened at the upper end of the storage shell, and an overflow brick is arranged at the lower end of the storage shell.
[0008] As a further solution of the utility model: the molten glass on both sides of the U-shaped overflow trough passes through the brick tips of the overflow bricks and sticks together to form a glass plate.
[0009] As a further solution of the utility model: a plurality of heat radiation ducts are inserted at equal intervals inside the connector.
[0010] As a further solution of the utility model: the material of the heat radiation air duct is one of a temperature-resistant corundum tube, a mullite corundum tube, and a silicon nitride tube.
[0011] As a further solution of the utility model: the material of the high temperature resistant wire is high temperature fire resistant glue.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] By setting the power, the air volume for adjusting the glass plate is changed from cold air to hot air, and within the width of the effective area of the glass plate, a heat radiation air duct is installed according to the thickness adjustment needs. On the one hand, the hot air volume is adjusted, and on the other hand, the heat radiation adjustment is used to soften the glass material and reduce the high point of the glass thickness. Through the use of the heat radiation air duct, the adjustment amount is greatly increased, effectively improving the thickness grade of the glass plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] like Figure 1-2 As shown, a heat radiation duct for online adjusting the thickness of liquid crystal glass comprises: a storage shell 2, a U-shaped overflow groove 1 is opened at the upper end of the storage shell 2, high-temperature glass liquid is stored in the U-shaped overflow groove 1, and an overflow brick is arranged at the lower end of the storage shell 2.
[0019] During the glass overflow and pull-down process, when the glass liquid overflows from both sides of the U-shaped overflow groove 1 and flows to the tip of the overflow brick, the glass liquid enters the thinning area. After passing through the tip of the overflow brick, the glass liquid on both sides sticks together and forms a glass plate 3 of a certain thickness under the traction of the traction mechanism.
[0020] Due to the inconsistency between the bottom design of the U-shaped overflow trough 1 and the flow material, the thickness of the glass plate 3 will appear wavy in the non-flow direction of the glass plate 3, with high points in the thickness, a large range, and poor overall quality.
[0021] Connectors 4 are symmetrically fixed on both sides of the glass plate 3 . The length of the connector 4 is greater than that of the glass plate 3 . Several heat radiation ducts 5 are inserted at equal intervals inside the connector 4 . Heating wires 6 are arranged inside the heat radiation ducts 5 .
[0022] The material of the heat radiation air duct 5 is one of a temperature-resistant corundum tube, a mullite corundum tube, and a silicon nitride tube.
[0023] One end of the heating wire 6 is welded with a high temperature resistant wire (not shown in the figure). Welding can ensure the stability of the connection and the reliability of power transmission.
[0024] The material of the high temperature resistant wire is high temperature refractory glue. The high temperature refractory glue is specially designed and processed so as to withstand higher temperatures, thereby ensuring that the high temperature resistant wire can operate safely in a high temperature environment.
[0025] The end of the high temperature resistant wire away from the heating wire 6 is connected to a power regulator (not shown in the figure). The high temperature resistant wire can transmit electrical energy from the power regulator to the heating wire 6 to ensure stable and safe electrical energy transmission.
[0026] By setting the power of the power regulator according to the extreme difference of the thickness high point, the heating effect of the heating wire 6 can be controlled. The heating wire 6 heats the air to increase its temperature. The heated hot air has a certain heat and radiation capacity after passing through the heat radiation air duct 5. The heat and radiation of the heat radiation air duct 5 itself will soften the thickness area and reduce the thickness high point, thereby eliminating the light and dark stripes formed on the glass plate 3 due to the thickness difference.
[0027] In this way, precise control of air temperature can be achieved to meet heating needs under different environmental conditions.
[0028] Working principle:
[0029] By setting the power of the power regulator according to the extreme difference of the thickness high point, the heating effect of the heating wire 6 can be controlled. The heating wire 6 heats the air to increase its temperature. The heated hot air has a certain heat and radiation capacity after passing through the heat radiation air duct 5. The heat and radiation of the heat radiation air duct 5 itself will soften the thickness area and reduce the thickness high point, thereby eliminating the light and dark stripes formed on the glass plate 3 due to the thickness difference.
[0030] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
