Description

Technical Field

[0001] This utility model belongs to the field of liquid crystal glass substrate production technology, specifically relating to a furnace sealing device after the substrate glass traction roller exits. Background Technology

[0002] In the production process of LCD glass substrates, molten glass solidifies and is drawn into glass sheets of the required dimensions in a forming furnace. These sheets are then transported to the subsequent board-oriented division (BOD) for cutting. An annealing furnace is located below the forming furnace and above the subsequent BOD cross-cutting machine. As the glass sheets pass through the annealing furnace, the traction rollers overcome the influence of surface tension, allowing the glass sheets to achieve the desired width and improving the flatness of the glass surface.

[0003] In an annealing furnace with known existing equipment and technology, the glass plate is held at both ends by traction rollers and is pulled down to form an overflow. The boss surface of the traction roller contacts and holds the glass plate, and the glass plate is driven downward by friction. As the traction roller is used for a longer period, the clamping force between the roller's boss surface and the glass plate gradually weakens, and a significant deviation occurs between the roller's center and the glass plate, affecting product quality. Simultaneously, during production, unforeseen events such as plate breakage inevitably occur, requiring immediate machine shutdown and traction roller replacement. During replacement, the traction roller must be removed from the furnace. Once removed, the traction roller detaches from the furnace body, causing heat to dissipate from the exposed surface. Furthermore, due to the limited space connecting the traction roller to the furnace, personnel cannot promptly seal the gap. Prolonged sealing operations cause a rapid drop in the furnace's internal temperature, affecting the glass plate's surface temperature. This leads to the rapid cooling of the 400°C glass plate. Influenced by external temperatures, the glass plate surface may locally warp, causing cracks and preventing normal flow. This not only impacts production efficiency but also significantly delays traction roller replacement, resulting in substantial production losses. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a furnace body sealing device after the substrate glass traction roller is withdrawn, so as to solve the technical problem that in the existing device, the furnace body surface is exposed after the traction roller is withdrawn, and the lack of a special structure for rapid sealing causes the furnace body internal temperature to drop rapidly.

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

[0006] This utility model provides a furnace body sealing device after the substrate glass traction roller retracts, including a sealing component, a traction roller, and a slide rail seat. The traction roller is disposed inside the furnace body to be sealed, and two slide rail seats are provided, which are respectively disposed on both sides of the connection between the traction roller and the furnace body to be sealed. The sealing component is disposed between the two slide rail seats.

[0007] Preferably, the slide rail base has a right-angled structure.

[0008] Preferably, a connecting component for controlling the movement of the sealing component within the slide rail is connected to the outer surface of the sealing component.

[0009] Preferably, the connecting assembly includes a first telescopic rod disposed on the outer surface of the sealing component, a second telescopic rod disposed below the first telescopic rod, and a movable telescopic rod disposed between the first telescopic rod and the second telescopic rod.

[0010] Preferably, the first telescopic rod, the second telescopic rod, and the movable telescopic rod are arranged in parallel.

[0011] Preferably, the first telescopic rod and the second telescopic rod are welded to the outer surface of the sealing component, and the movable telescopic rod is connected to the outer surface of the sealing component via a connecting frame.

[0012] Preferably, the connecting frame is vertically connected to the sealing component, and the top of the connecting frame is connected to the movable telescopic rod by fixing bolts.

[0013] In the above technical solution, the vertical connection makes the sealing component bear force evenly, maximizing its load-bearing capacity, and the threaded connection facilitates the application of vertical pressure to the traction roller.

[0014] Preferably, the connecting frame has a U-shaped structure.

[0015] Preferably, a traction roller pressure block is connected at the connection port between the traction roller and the furnace body.

[0016] In the above technical solution, the traction roller pressing block enhances the connection strength between the traction roller and the furnace body, preventing the furnace body structure from deforming when the traction roller is withdrawn.

[0017] More preferably, the slide rail base, sealing component, connecting frame, first telescopic rod, second telescopic rod, and movable telescopic rod are made of high-temperature resistant stainless steel.

[0018] Preferably, the sealing component has a rounded rectangular structure.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This invention proposes a furnace body sealing device after the substrate glass traction roller retracts. A sealing component is installed on a slide rail at the connection between the traction roller and the furnace body. When the traction roller retracts from the furnace body, the sealing component slides into the slide rail, sealing the furnace opening and preventing the leakage of high-temperature gas and the entry of outside air, thus maintaining a stable temperature field and atmosphere inside the furnace. The slide rail provides a fixed movement path for the sealing component, ensuring that it quickly and accurately inserts into the furnace opening, thereby preventing a rapid drop in temperature inside the furnace.

[0021] Furthermore, the connecting component enables remote control of the sealing component, avoiding direct manual contact with high-temperature areas. The connecting component also ensures that the sealing component moves directionally along the slide rail, improving the stability and sealing efficiency of the sealing action.

[0022] Furthermore, the first and second telescopic rods serve as basic connections and supports. Users can hold the first and second telescopic rods to fix the device in place, ensuring the initial positioning and basic stability of the sealing component on the furnace body, and enabling it to withstand a certain static load.

[0023] Furthermore, the parallel structure ensures that the first telescopic rod, the second telescopic rod, and the movable telescopic rod extend and retract synchronously, improving the stability of the sealing component's movement. In addition, the parallel layout reduces the interference of the telescopic rods on the operating space, making it suitable for narrow environments around the furnace.

[0024] Furthermore, the welding of the first and second telescopic rods allows them to form a robust whole, providing high connection strength and rigidity. This meets the requirements of the sealing component under normal operating conditions, including the combined loads of furnace pressure and temperature stress, ensuring that the connection will not easily loosen or break, guaranteeing long-term reliability. It also eliminates potential gaps in bolted connections, enhancing the response speed and precision of mechanical operations. The movable connecting rod is connected to the sealing component via a connecting frame, facilitating position adjustment of the sealing component by adjusting the angle of the movable connecting rod.

[0025] Furthermore, the U-shaped structure of the connecting frame enhances its flexibility and adjustability. The U-shape allows the movable connecting rod to move or swing within a certain range, facilitating the adjustment of the sealing component's position. For example, when sliding the sealing component into the slide rail seat, it is easier to align with the holes in the slide rail seat, allowing it to adapt to minor displacements and deformations during use, ensuring the sealing component is always in the correct working position.

[0026] Furthermore, the vertical connection provides the sealing component with dual axial and radial adjustment freedom, adapting to the fitting requirements of the inner wall of the slide rail seat. The vertical structure counteracts the lateral force when the sealing component is pushed in, preventing deformation of the slide rail seat. The threaded connection supports quick disassembly and assembly, facilitating the replacement of damaged components. Millimeter-level displacement adjustment of the movable telescopic rod can be achieved by rotating the thread, improving the positional accuracy of the sealing component.

[0027] Furthermore, the function of the traction roller pressure block is to apply pressure to the traction roller, ensure the stable operation of the traction roller, guarantee the uniform tension of the substrate glass during the traction process, ensure smooth transmission, and prevent phenomena such as deviation and shaking of the glass belt.

[0028] Furthermore, the use of stainless steel material avoids structural misalignment or seal failure caused by temperature differences.

[0029] Furthermore, during the installation and disassembly of the sealing components, the rounded rectangular structure is less likely to collide or scratch with surrounding components, facilitating the placement and removal of the sealing base on equipment such as the furnace body, and reducing the risk to operators and equipment components.

[0038] The purpose of this invention is to address the issue that after the traction roller 4 exits the furnace body 1 to be sealed, the heat on the exposed surface of the furnace body 1 dissipates outwards.

[0050] The operability of the sealing component 5, the first telescopic rod 6, the second telescopic rod 7, and the movable telescopic rod 8 makes it convenient for operators to hold and seal during operation, preventing burns and reducing the need to use the hand-held velvet blanket to seal the furnace body, while also improving safety and efficiency.
