Description

Technical Field

[0001] This utility model relates to the field of glass processing, specifically to a receiving device for molten glass forming. Background Technology

[0002] In current technologies, especially during the sample melting process, when casting high-temperature glass, a handheld special clamp is used to hold the crucible containing molten glass taken from the high-temperature furnace. The molten glass is then poured into a special mold. When the glass temperature drops to a certain level, it is demolded. First, the mold frame is removed, and then the glass is moved from the bottom plate of the mold to the receiving plate. The glass is then sent to a special annealing furnace for annealing to eliminate permanent and temporary stresses in the glass.

[0003] The problem with the existing technology is that annealed glass samples develop cracks of varying sizes at the edges, affecting their normal use and processing. This is due to two reasons: 1. The surface temperature of the receiving plate and the temperature of the molten glass differ too much. After the molten glass is formed, the higher temperature glass comes into contact with the lower temperature surface of the receiving plate, creating a significant temperature gradient. This temperature difference leads to variations in the formed glass samples, resulting in localized cracks during cooling. 2. The material of the receiving plate also has a certain influence on the resulting cracks. Utility Model Content

[0004] The purpose of this invention is to provide a receiving device for molten glass forming, in order to solve the problem of cracks in the glass manufacturing process in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model discloses a receiving device for molten glass forming, including a receiving plate, the bottom of which is connected to a heating device; the heating device includes a base and a heating element disposed within the base, wherein the heating element is spirally coiled within the base.

[0007] As a further improvement, the heating element is a resistance wire.

[0008] As a further improvement, the resistance wire thickness is less than 0.2 mm and the width is 2-3 mm.

[0009] As a further improvement, the base is also provided with a connector, which is connected to the resistance wire.

[0010] As a further improvement, the base is provided with a partition for spacing the resistance wires, wherein the resistance wires are spirally wound around the partition in sequence.

[0011] As a further improvement, a temperature sensor is provided inside the base.

[0016] Compared with the prior art, this utility model achieves the following technical effects:

[0017] This invention features a heating device at the bottom of the receiving plate. This device controls the surface temperature of the receiving plate to be close to the softening point of the molten glass, thus completely eliminating the temperature gradient problem caused by excessive temperature difference between the two. This device reduces the thermal stress caused by temperature differences during the receiving process of the cast glass, thereby effectively reducing the formation of cracks on the glass surface and further improving the quality of the glass.

[0026] The embodiments of this application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application. Rather, the embodiments of this application include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0027] Examples of this application are described in detail below, with examples shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The examples described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] like Figure 1 and Figure 2 The diagram shows a process diagram of the prior art. When the worker uses a hand clamp to pour the molten glass from the crucible into the mold, and the temperature of the molten glass drops to a certain temperature, it is demolded. Then the glass is moved from the bottom plate of the mold to the receiving plate, and then sent to a special annealing furnace for annealing.

[0030] like Figures 3-6 As shown, the present invention provides a receiving device for molten glass forming, including a receiving plate 1, the bottom of which is connected to a heating device; the heating device includes a base 2 and a heating element 7 disposed in the base 2, wherein the heating element 7 is spirally coiled in the base 2.

[0031] In this embodiment, a heating device is provided at the bottom of the receiving plate 1 to heat the surface temperature of the receiving plate 1 to a temperature close to the softening point of the molten glass. In this embodiment, the surface temperature of the receiving plate 1 is preferably 500°C to 600°C, while the softening point of the molten glass is 700°C to 800°C. By using the heating device to heat the receiving plate 1, the temperature difference between the receiving plate and the softening point of the molten glass is reduced, thereby reducing the occurrence of cracks on the glass.

[0032] The heating element 7 is a resistance wire. The resistance wire is less than 0.2 mm thick and 2-3 mm wide. In this embodiment, the resistance wire is nickel-chromium-aluminum, and the power can reach 3.5-5 kW. The entire resistance wire occupies the base 2, ensuring uniform heating.

[0033] The base 2 is also provided with a connector 3, which is connected to the resistance wire. In this embodiment, the resistance wire and the connector are connected, and the outer shell 4 has an opening for the connector 3 to protrude. The connector can be energized to heat the resistance wire, thereby heating the surface of the material plate 1.

[0034] The base 2 is provided with a partition 8 for spacing the resistance wires, wherein the resistance wires are spirally wound along the partition 8. Figure 5 As shown, the embodiment preferably includes five partitions 8, but it is not limited to this. The number of partitions 8 can be increased or decreased depending on the specific size of the receiving plate 1 or the application scenario. By separating the resistance wires with partitions 8, direct contact between the resistance wires can be avoided, reducing local overheating and thus improving the overall heating uniformity. At the same time, partitions 8 can effectively isolate the resistance wires, preventing short circuits caused by mutual contact and improving the safety of the equipment.

[0035] A temperature sensor is installed inside the base 2. In this embodiment, the temperature sensor is a thermocouple probe (not shown in the figure). The temperature detection part of the thermocouple probe passes through the base 2 and is connected to the receiving plate 1. The thermocouple probe is used to detect the temperature of the receiving plate 1; of course, if... Figure 6 As shown, an infrared thermometer can also be used to measure the surface temperature of the receiving plate 1, so that the surface of the receiving plate 1 reaches a suitable temperature.

[0036] It also includes a protective plate 6, which is located between the receiving plate 1 and the base 2. For example... Figure 4 As shown, in this embodiment, the protection plate 6 is specifically an insulating plate. The size of the protection plate 6 is adapted to the size of the base 2, and it completely covers the resistance wire to isolate current and prevent leakage and short circuit.

[0037] It also includes a housing 4 that is fitted over the base 2. In this embodiment, the housing 4 is designed to enclose the base 2, providing physical protection for the base 2 and internal components such as the resistance wire, preventing them from being corroded and damaged by the external environment. It also has functions such as dustproof, waterproof, and corrosion-proof, ensuring the long-term stable operation of the device.

[0038] The receiving plate 1 is connected to a handle 5 at one end. The handle 5 is designed for easy gripping.

[0039] The receiving plate 1 is a ceramic fiber board. The ceramic fiber board selected in this embodiment can remain stable in high-temperature environments and has a wide operating temperature range, typically between 600°C and 1200°C. In addition, at high temperatures, the ceramic fiber board is not easily deformed, melted, or subjected to harmful chemical reactions, thereby ensuring the stability and safety of the receiving process.
