[0045] The embodiments of this application are described below with reference to the accompanying drawings:

[0046] refer to Figures 1 to 8 According to an embodiment of this application, a protective component is used to protect a molten glass body 200, which is used to contact high-temperature molten glass to limit the flow path of the high-temperature molten glass and guide it from the furnace to the rolling mill. Along a first direction, an extension 210 protrudes from one side of the molten glass body 200, and the extension 210 has an extension wall 211. The molten glass body 200 also includes a top wall 220 and a bottom wall 230. The extension wall 211 extends from the top wall 220 to the bottom wall 230 of the molten glass body 200. The extension 210 is configured to cross-sectionally bisect the extension 210 along a plane perpendicular to the first direction, and the cross-sectional area of ​​the extension 210 gradually decreases.

[0047] The calendering apparatus includes an upper calendering roll and a lower calendering roll. A portion of the extension 210 can penetrate into the area between the upper calendering roll and the lower calendering roll along a first direction. The extension 210 is used to guide the flow of high-temperature molten glass in a longer path, improve the quality of the glass sheet formed by the upper calendering roll and the lower calendering roll, and thereby reduce the size of the cleared edge of the glass sheet, which is beneficial to reducing the production cost of photovoltaic glass.

[0048] refer to Figures 1 to 7Based on the structure of the aforementioned brick-guarding body 200, the protective component of this application includes a first component 110, a second component 120, a third component 130, and a fourth component 140. Along a second direction, the first component 110 and the second component 120 are spaced apart. The second direction is perpendicular to the first direction, which should be understood as the conveying direction of the high-temperature molten glass. The third component 130 is provided with a limiting groove 131. Along the second direction, one end of the third component 130 is connected to the side of the first component 110 facing the second component 120, and the other end of the third component 130 is connected to the side of the second component 120 facing the first component 110. Along the first direction, the fourth component 140 and the third component 130 are spaced apart, and the opening of the limiting groove 131 is oriented toward the fourth component 140. Along the second direction, one end of the fourth component 140 is connected to the side of the first component 110 facing the second component 120, and the other end of the fourth component 140 is connected to the side of the second component 120 facing the first component 110. The limiting groove 131 is used to accommodate a part of the extension 210 to protect the edge area of ​​the extension 210, avoid defects such as breakage in the edge area of ​​the extension 210, and help extend the service life of the brick body 200.

[0049] Specifically, the first component 110, the second component 120, the third component 130, and the fourth component 140 are connected. The first component 110 and the second component 120 are spaced apart along a second direction, and the third component 130 and the fourth component 140 are spaced apart along a first direction. The first component 110, the second component 120, the third component 130, and the fourth component 140 together enclose a closed area surrounding the brick-guarding body 200. A portion of the brick-guarding body 200 is placed within the closed area. The first component 110, the second component 120, and the fourth component 140 are used to abut against the brick-guarding body 200 and cover the side wall of the brick-guarding body 200 near the bottom wall 230, thereby protecting the edge area of ​​the brick-guarding body 200.

[0050] refer to Figures 1 to 7For example, the sidewalls of the guard body 200 include a first sidewall 241, a second sidewall 242, and a third sidewall 243. The upper sides of the first sidewall 241, the second sidewall 242, and the third sidewall 243 are all connected to the top wall 220 of the guard body 200, and the lower sides of the first sidewall 241, the second sidewall 242, and the third sidewall 243 are all connected to the bottom wall 230 of the guard body 200. Along the second direction, the first sidewall 241 and the second sidewall 242 are located on opposite sides of the guard body 200. Along the first direction, the third sidewall 243 is disposed opposite to the extension wall 211. At least one side of the first sidewall 241 and the second sidewall 242 is used to contact and guide the flow of molten glass. The area where the molten glass contacts the first sidewall 241 and / or the second sidewall 242 includes the side of the first sidewall 241 and / or the second sidewall 242 closest to the bottom wall 230. The first component 110 abuts against the first sidewall 241 and covers the side of the first sidewall 241 near the bottom wall 230. The second component 120 abuts against the second sidewall 242 and covers the side of the second sidewall 242 near the bottom wall 230. The sides of the first sidewall 241 and the second sidewall 242 near the bottom wall 230 are the edge areas of the brick-protecting body 200. The first component 110 and the second component 120 can block the scouring and erosion of the molten glass, thereby protecting the brick-protecting body 200.

[0051] In addition, the fourth component 140 is used to abut against the third side wall 243, and cooperates with the limiting groove 131 of the third component 130 to receive the extension 210, so as to limit the brick body 200 along the first direction.

[0052] It should be noted that the first component 110, the second component 120, the third component 130, and the fourth component 140 can be connected by welding, snap-fit, bolts, or other connection methods. The protective components of this application can be made of materials with corrosion resistance and oxidation resistance, such as 0Cr25Ni20 and 0Cr25Ni20Si2, which facilitate resistance to the erosion and corrosion of molten glass, prevent defects such as breakage in the edge area of ​​the protective brick body 200, extend the service life of the protective brick body 200, and ensure the stability of photovoltaic glass production.

[0053] refer to Figures 1 to 3 In some embodiments, along a first direction, one end of the first component 110 is provided with a first tip 111, and the cross-sectional area of ​​the first tip 111 gradually decreases; one end of the second component 120 is provided with a second tip 121, and the cross-sectional area of ​​the second tip 121 gradually decreases. For example, the first tip 111 and the second tip 121 may be triangular, and the first tip 111 and the second tip 121 are used to pass through the area between the upper and lower calendering rolls. At least one of the first tip 111 and the second tip 121 is used to guide the molten glass to flow toward the calendering apparatus.

[0054] Along the second direction, one end of the third component 130 is connected to the side of the first tip 111 facing the second component 120, and the other end of the third component 130 is connected to the side of the second tip 121 facing the first component 110. The third component 130 is used to ensure the connection between the first component 110 and the second component 120. Furthermore, by providing a limiting groove 131 to accommodate the extension 210, the third component 130 ensures that after the brick guard body 200 and the protective component are assembled, along the first direction, the first tip 111, the second tip 121, and the extension 210 are on the same side (which should be understood as the side closer to the rolling device). The first tip 111, the second tip 121, and the extension 210 cooperate with each other to avoid the upper and lower rolling rollers, further extending the guiding path of the glass melt, which is beneficial to reducing the size of the glass plate cleaning edge and reducing the production cost of photovoltaic glass.

[0055] It should be noted that by setting the first tip 111 and the second tip 121, this application can avoid the upper and lower calendering rolls, so that the structure formed by the assembly of the protective component and the brick guard body 200 is closer to the calendering device, thereby extending the guiding path of the glass melt. Within the guiding path, along the second direction, the size of the glass melt coverage area remains unchanged, which is beneficial to improving the edge quality of the glass and reducing the losses caused by edge cleaning in the production of photovoltaic glass.

[0056] refer to Figures 1 to 6 In some embodiments, along a first direction, at least one of the first tip 111 and the second tip 121 protrudes outward toward the side of the third component 130 away from the fourth component 140, while a portion of the extension 210 is received in the limiting groove 131. Thus, at least one of the first tip 111 and the second tip 121 is extended relative to the extension 210, and the first tip 111 or the second tip 121 can penetrate deeper into the region between the upper calendering roll and the lower calendering roll relative to the extension 210. The region between the upper calendering roll and the lower calendering roll includes the calendering section. The extension of the first tip 111 and / or the second tip 121 shortens the distance from the first tip 111 or the second tip 121 to the calendering section, which is beneficial to further improve the forming quality of the glass sheet and reduce the material loss caused by the edge cleaning of the glass sheet.

[0057] It should be noted that molten glass tends to flow along the second direction in the area from the first tip 111 or the second tip 121 to the rolling section, which affects the forming quality of the glass sheet. Therefore, shortening the distance from the first tip 111 or the second tip 121 to the rolling section can improve the restriction on the flow of molten glass along the second direction, thereby ensuring the forming quality of the glass sheet edge and reducing the need for edge trimming of the glass sheet.

[0058] Furthermore, the fact that at least one of the first tip 111 and the second tip 121 protrudes outward toward the side of the third component 130 that is away from the fourth component 140 should be understood as the first tip 111 protruding outward toward the side of the third component 130 that is away from the fourth component 140, or the second tip 121 protruding outward toward the side of the third component 130 that is away from the fourth component 140, or both the first tip 111 and the second tip 121 protruding outward toward the side of the third component 130 that is away from the fourth component 140.

[0059] refer to Figures 1 to 6 In some embodiments, along the second direction, the first component 110 has a first thickness, the second component 120 has a second thickness, and along the first direction, the fourth component 140 has a third thickness. At least one of the first and second thicknesses is less than the third thickness, that is, at least one of the first component 110 and the second component 120 is thinner than the fourth component 140 (i.e., the fourth component 140 has a greater thickness). The fourth component 140 is used to cover the side of the third sidewall 243 near the bottom wall 230, and along the first direction, the third sidewall 243 is located on the opposite side of the extension 210. Therefore, the cooperation between the fourth component 140 and the third component 130 can restrict the movement of the brick-guarding body 200 relative to the protective assembly along the first direction. The thicker setting of the fourth component 140 is beneficial to increasing the stability of the brick-guarding body 200.

[0060] In addition, the first component 110 is used to cover the side of the first sidewall 241 near the bottom wall 230, and the second component 120 is used to cover the side of the second sidewall 242 near the bottom wall 230. For example, if the first sidewall 241 is used to contact the molten glass, the first component 110 is thinner than the fourth component 140. A part of the contact area between the first sidewall 241 and the molten glass is covered by the first component 110. The thinner design of the first component 110 allows the molten glass to be conducted to the side of the first sidewall 241 near the bottom wall 230 more quickly. As a result, in the contact area between the first sidewall 241 and the molten glass, the temperature of the part covered by the first component 110 is closer to that of the part not covered by the first component 110. This helps to reduce the thermal stress inside the brick body 200 and effectively avoids defects such as cracks caused by temperature differences in the brick body 200.

[0061] Similarly, if the second sidewall 242 is used to contact the molten glass, then the second component 120 is thinner than the fourth component 140, which helps to reduce the thermal stress on the side where the second sidewall 242 is located and ensures the integrity of the main body 200. Alternatively, if both the first sidewall 241 and the second sidewall 242 are used to contact the molten glass, then both the first component 110 and the second component 120 are thinner than the fourth component 140, which helps to reduce stress concentration inside the main body 200.

[0062] The first and second thicknesses can be in the range of 2.5mm to 5mm. For example, the first and / or second thicknesses can be any value among 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm and 5mm. The third thickness can be in the range of 5mm to 10mm. For example, the third thickness can be any value among 5mm, 6mm, 7mm, 8mm, 9mm and 10mm.

[0063] It should be noted that the height of the molten glass is insufficient to contact the side of the first sidewall 241 and / or the second sidewall 242 near the top wall 220. Therefore, it is only necessary to set up a protective barrier on the side of the first sidewall 241 and / or the second sidewall 242 near the bottom wall 230 to prevent the molten glass from scouring and eroding the edge area of ​​the brick-guarding body 200 near the bottom wall 230, thus avoiding defects in the brick-guarding body 200 that could affect the stable production of photovoltaic glass.

[0064] refer to Figures 1 to 8 According to the embodiments of this application, the brick-guarding device includes a brick-guarding body 200 and a protective component as described in any of the above embodiments. Along a first direction, an extension 210 is provided on one side of the brick-guarding body 200. The extension 210 is provided with an extension wall 211, which extends from the top wall 220 of the brick-guarding body 200 to the bottom wall 230 of the brick-guarding body 200. The extension 210 is configured to cross the extension 210 in a plane perpendicular to the first direction. The cross-sectional area of ​​the extension 210 gradually decreases. The protective component is connected to the brick-guarding body 200 and covers the side of the brick-guarding body 200 where the side wall and the bottom wall 230 are connected. This is used to block the scouring and erosion of the edge area of ​​the brick-guarding body 200 by the molten glass, effectively avoiding defects such as breakage of the brick-guarding body 200 and ensuring the stable production of photovoltaic glass.

[0065] refer to Figures 1 to 8 In some embodiments, the brick guarding device further includes a drive component 300 connected to the brick guarding body 200. The drive component 300 is configured to drive the brick guarding body 200 to move along a second direction (i.e., perpendicular to the flow direction of the molten glass) to adjust the production width of the photovoltaic glass, which is beneficial to improving the adaptability of the brick guarding device and realizing the production of photovoltaic glass of various widths.

[0066] Specifically, the drive assembly 300 includes a fixed part and a rotating part. The fixed part can be a nut with internal threads, and the rotating part can be a screw with external threads. The rotating part is threadedly connected to the brick guard body 200. The fixed part and the rotating part are connected by threads. The fixed part is used to fix to a structure that is stationary relative to the ground, such as a frame. The rotating part is driven to rotate relative to the fixed part, and at the same time drives the brick guard body 200 to move in a second direction to realize the adjustment of the glass production width.

[0067] It should be noted that the drive component 300 is not limited to the above structure. The drive component 300 can also be a gear and rack structure, a pneumatic cylinder, a hydraulic cylinder, or a linear motor module, etc., which can drive the brick-guarding body 200 to move linearly.

[0068] refer to Figures 1 to 8 In some embodiments, the extension wall 211 is a curved wall. During the photovoltaic glass production process, the brick guarding device and the rolling device are arranged adjacent to each other along a first direction. The extension wall 211 is concave towards the side away from the rolling device. The rolling device includes an upper rolling roll and a lower rolling roll. The extension wall 211 is configured to have the same curvature as the rolling roll, which facilitates the arrangement of the extension wall 211 and the rolling roll at a closer distance. Thus, the brick guarding device and the rolling device are closer together, which is beneficial to shortening the distance from the brick guarding device to the rolling section of the rolling device, thereby ensuring the production quality of photovoltaic glass.

[0069] refer to Figures 1 to 8 According to the embodiments of this application, the edge-blocking device includes a lip brick 400 and two brick-guarding devices as described in any of the above embodiments. Along the second direction, the two brick-guarding devices are spaced apart. The lip brick 400 abuts against the bottom wall 230 of the two brick-guarding devices, that is, the lip brick 400 serves as a base and simultaneously supports the two brick-guarding devices. The two brick-guarding devices and the lip brick 400 together define a flow channel 410, which is used to guide the flow of molten glass, thereby ensuring that the width of the molten glass flowing to the rolling device is basically consistent.

[0070] refer to Figures 1 to 8 In other embodiments, both brick guarding devices include a drive component 300. The two drive components 300 can drive the two brick guarding bodies 200 to move in a one-to-one correspondence, thereby adjusting the width of the drainage channel 410 (i.e., the distance between the two brick guarding devices along the second direction), which is beneficial to improving the adaptability of the edge guarding device.

[0071] refer to Figures 1 to 8 In some embodiments, the bottom of the brick guarding body 200 is provided with a limiting protrusion 250, and the lip brick 400 is provided with a positioning groove on the side facing the brick guarding device. The limiting protrusion 250 is located in the positioning groove. The cooperation between the limiting protrusion 250 and the limiting groove facilitates the determination of the installation position of the brick guarding body 200.

[0072] For example, the lip brick 400 serves as a base and has a defined relative position with the rolling device. Based on this, when installing the guard brick body 200, it is only necessary to place the limiting protrusion 250 in the positioning groove to determine the relative position between the guard brick body 200 and the lip brick 400. Consequently, the relative position between the guard brick body 200 and the rolling device can also be determined. Thus, the setting of the limiting protrusion 250 and the limiting groove is beneficial to shortening the assembly time of the edge-blocking equipment.

[0073] refer to Figures 1 to 8According to an embodiment of this application, a glass production line includes a rolling mill and a baffle device as described in any of the above embodiments. Along a first direction, the baffle device is located on one side of the rolling mill, and the flow channel 410 faces the rolling mill. The baffle device is installed at the overflow port of the furnace. The high-temperature molten glass flowing out of the furnace is guided to the rolling mill through the flow channel 410. The rolling mill is used to squeeze the molten glass to form a softened glass strip. By restricting the flow path of the high-temperature molten glass through the flow channel 410, the edge quality of the glass strip is improved, thereby reducing the edge size of the glass, saving production materials, and lowering production costs.

[0074] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
