Description

Technical Field

[0001] This invention relates to the field of photovoltaic glass production technology, and in particular to a rolled glass edge-stopping device that is adjustable in front and back and in height. Background Technology

[0002] As photovoltaic glass forming technology continues to develop, in order to enhance the cooling capacity of calendering rolls and improve the production efficiency of photovoltaic glass, large-diameter calendering rolls have gradually become the mainstream choice. When the diameter of the calendering rolls increases, if the original production height of the calendering rolls is maintained, the contact area between the upper and lower calendering rolls and the molten glass will be different, resulting in the upper roll overheating and the lower roll undercooling, causing quality defects such as hot roller marks and orange peel on the glass surface.

[0003] Currently, many photovoltaic glass manufacturers have to reduce the wall thickness of the upper roller in order to balance the temperature of the upper and lower rollers. However, this limits the forming and drawing speed of photovoltaic glass, preventing the calender from fully releasing its capacity. This is a common phenomenon in the forming process of photovoltaic glass factories and has become a technical bottleneck restricting the improvement of photovoltaic glass forming technology, which urgently needs to be solved. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a front-to-back and height-adjustable rolled glass edge-blocking device. By adding a height-adjustable edge-blocking assembly with a waist-shaped hole in the base, the edge-blocking assembly can move up and down and back and forth in coordination with the rolling mill. This allows for free adjustment of the rolling mill position to balance the temperature of the upper and lower rolling rollers and maintain the distance between the lower rolling roller and the lip brick. Furthermore, the front-to-back extension and retraction of the sealing brick assembly can compensate for the gaps generated by the front-to-back movement of the edge-blocking assembly, preventing molten glass from overflowing between the edge-blocking assembly and the sealing brick assembly. This solves the problem of temperature imbalance between the upper and lower rolling rollers in the rolled glass production process.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An adjustable rolled glass edge-stop device with front-to-back and height adjustment is installed on both sides of the rolled glass overflow outlet, comprising: A lifting edge assembly, wherein the lifting edge assembly is adjustablely installed at both ends of the lip brick; A sealing brick assembly is installed at both ends of the tail brick and dynamically compensates for the forward and backward displacement of the lifting edge assembly.

[0006] As a preferred embodiment, the lifting and lowering edge assembly includes an edge assembly and a lifting mechanism. The lifting mechanism synchronously drives the edge assembly to move up and down, so that the upper and lower arc surfaces of the edge assembly are respectively positioned close to the upper and lower calendering rolls of the calender.

[0007] As a preferred embodiment, the lifting mechanism is disposed below the sidewall assembly, and includes: The drive end is connected to the bottom of the flange assembly; and A guide section used to limit the driving direction.

[0008] As a preferred embodiment, the lifting mechanism further includes a base and a support portion, with the drive portion installed in the middle of the base; the support portion is installed on the bottom surface of the sidewall assembly, and the drive end of the drive portion is connected to the support portion; the base is provided with a plurality of mounting holes.

[0009] As a preferred embodiment, the mounting hole is an oblong hole, the length of which is consistent with the forming direction of the rolled glass.

[0010] As a preferred embodiment, the sealing brick assembly comprises: The fixing part abuts against the side wall of the overflow port, and its side facing the molten glass is located on the same plane as the side wall; The movable part includes at least a first side plate parallel to the sidewall and a second side plate perpendicular to the first side plate; and An adjustment mechanism is horizontally adjustable to connect the moving part and the fixed part, and its adjustment direction is parallel to the first side plate.

[0011] As a preferred embodiment, the adjustment mechanism includes a threaded rod vertically mounted on the inner side of the second side plate and a nut sleeved on the threaded rod.

[0012] As a preferred embodiment, the surface of the fixing part facing the second side plate includes a column hole, and the threaded rod is adapted to be installed in the column hole.

[0013] As a preferred embodiment, the rotation of the nut controls the distance between the second side plate and the fixing part, so that the second side plate remains in contact with the lifting stop assembly.

[0014] As a preferred embodiment, the movable part is L-shaped, with its first side plate and second side plate integrally formed.

[0015] The beneficial effects of this invention are as follows: (1) The present invention adds a lifting edge assembly with waist holes on the base at both ends of the lip brick, so that the edge assembly can move up and down and back and forth with the upper and lower calendering rollers, thereby removing the restriction of the edge assembly on the position of the upper and lower calendering rollers. The position of the calender can be freely adjusted to balance the temperature of the upper and lower calendering rollers and maintain the distance between the lower calendering roller and the lip brick, thereby expanding the photovoltaic glass forming operation process window, stabilizing production, further improving the drawing speed, and improving the overall production efficiency of the product.

[0016] (2) By setting a sealing brick assembly with a movable part, when the lifting and lowering edge assembly moves back and forth in coordination with the upper and lower rolling rollers, a gap will appear between the edge assembly and the sealing brick assembly. At this time, the gap can be compensated by operating the adjustment mechanism to extend and retract the movable part, thus preventing the glass liquid from leaking between the edge assembly and the sealing brick assembly.

[0017] (3) The present invention limits the minimum distance between the second side plate and the fixed part by using a nut. Rotating the nut expands this distance so that the second side plate remains in contact with the lifting edge assembly, and the fit between the fixed part and the side wall is also tighter.

[0018] (4) By setting a physical isolation layer, the present invention makes the fit of multiple workpieces tighter, reduces the precipitation and crystallization of glass liquid in the gaps, and improves the production quality of rolled glass. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] Example 1 like Figure 1-7 As shown, this embodiment provides a front-to-back and lifting adjustable rolled glass edge device, installed on both sides of the rolled glass overflow port, including: a lifting edge assembly 1, which is installed front-to-back adjustablely on both ends of the lip brick 3; and a sealing brick group 2, which is installed on both ends of the tail brick 4 and compensates for the front-to-back displacement of the lifting edge assembly 1.

[0023] like Figure 1-3 As shown, the lifting edge assembly 1 includes an edge assembly 5 and a lifting mechanism 6. The lifting mechanism 6 synchronously drives the edge assembly 5 to move up and down, so that the upper arc surface 51 and the lower arc surface 52 of the edge assembly 5 are respectively positioned close to the upper and lower calendering rolls of the calendering machine. The edge assembly includes a metal edge 53. In this embodiment, the edge assembly 5 can be an existing edge brick structure plus a bottom seat brick, with the two connected by fasteners and a physical isolation layer provided at the connection. This design can save production costs and eliminate the need to remanufacture the edge brick; alternatively, the edge brick structure and the seat brick can be integrally formed, which has greater strength and a longer service life.

[0024] The lifting mechanism 6 is disposed below the side guard assembly 5, and includes: a driving part 61 whose driving end is connected to the bottom of the side guard assembly 5; and a guide part 62 for limiting the driving direction. The lifting mechanism 6 also includes a base 63 and a support part 64. The driving part 61 is installed in the middle of the base 63; the support part 64 is installed on the bottom surface of the side guard assembly 5, and the driving end of the driving part 61 is connected to the support part 64; the base 63 is provided with a plurality of mounting holes 65. The driving part 61 can be manually or electrically controlled, and the guide part 62 restricts the movement direction of the side guard assembly 5, so that it can only move vertically.

[0025] like Figure 1 As shown, the mounting hole 65 is an oblong hole, and its length direction is consistent with the forming direction of the rolled glass. By adding a lifting baffle assembly 1 with an oblong hole on the base 63 at both ends of the lip brick 3, the baffle assembly 5 can move up and down and back and forth with the upper and lower calendering rollers, thereby removing the restriction of the baffle assembly on the position of the upper and lower calendering rollers. The position of the calender can be freely adjusted to balance the temperature of the upper and lower calendering rollers and maintain the distance between the lower calendering roller and the lip brick 3, thereby expanding the photovoltaic glass forming operation process window, stabilizing production, further improving the drawing speed, and improving the overall production efficiency of the product.

[0026] like Figure 1-3 As shown, the sealing brick assembly 2 includes: a fixing part 7, which abuts against the side wall 10 of the overflow port, and its side facing the molten glass is located on the same plane as the side wall 10; a moving part 8, which includes at least a first side plate 81 parallel to the side wall 10 and a second side plate 82 perpendicular to the first side plate 81; and an adjusting mechanism 9, which is horizontally adjustable to connect the moving part 8 and the fixing part 7, and its adjusting direction is parallel to the first side plate 81.

[0027] By setting a sealing brick assembly 2 with a movable part 8, when the lifting and lowering edge assembly 1 moves back and forth in coordination with the positions of the upper and lower rolling rollers, a gap will appear between the edge assembly 5 and the sealing brick assembly 2. At this time, the gap can be compensated by operating the adjustment mechanism 9 to extend and retract the movable part 8, thus preventing the glass liquid from leaking between the edge assembly 5 and the sealing brick assembly 2.

[0028] like Figure 1-3As shown, the adjusting mechanism 9 includes a threaded rod 91 vertically mounted on the inner side of the second side plate 82 and a nut 92 sleeved on the threaded rod 91. The surface of the fixing part 7 facing the second side plate 82 includes a post hole 71, and the threaded rod 91 is adapted to be installed in the post hole 71. The rotation of the nut 92 controls the distance between the second side plate 82 and the fixing part 7. The nut 92 limits the minimum distance between the second side plate 82 and the fixing part 7. Rotating the nut 92 increases this distance, so that the second side plate 82 remains in contact with the lifting edge assembly 1, and at the same time, the fit between the fixing part 7 and the side wall 10 is also tighter.

[0029] The movable part 8 is L-shaped, with its first side plate 81 and second side plate 82 integrally formed. The inner wall of the first side plate 81 abuts against the fixed part 7 to prevent molten glass from leaking between the first side plate 81 and the fixed part 7.

[0030] It should be noted that the reason this invention requires adjustment of the calender mill is that when the calender rolls rise, if they rise vertically, the distance between the lower roll surface and the edge of the lip brick 3 will become increasingly shorter. Figure 5-7 As shown, if the upper and lower calendering rolls are not moved forward, the distance between the calendering rolls and the lip brick will gradually decrease until interference occurs. Figure 5-7 The dashed line in the middle represents the equidistant circle between the lip brick 3 and the lower calendering roll. In order to ensure that the lower calendering roll is always tangent to this circle, it is essential for the calender to move forward.

[0031] Example 2 like Figure 1 , 3 As shown, components that are the same as or corresponding to those in Embodiment 1 are marked with the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 will be described below. The difference between Embodiment 2 and Embodiment 1 is that a physical isolation layer 11 is provided between the fixing part 7 and the first side plate 81. The physical isolation layer 11 is installed on the side of the fixing part 7, and its outer side abuts against the first side plate 81. The physical isolation layer 11 is made of fire-resistant and high-temperature resistant material, such as zirconium fiber felt. The physical isolation layer 11 can protect the fixing part 7, extend the service life of the sealing brick assembly, and make the fit between the first side plate 81 and the fixing part 7 tighter, preventing molten glass from entering the gap between the first side plate 81 and the fixing part 7 and precipitating crystals, thus affecting the quality of rolled glass production.

[0032] Example 3 like Figure 1 , 3As shown, components that are the same as or corresponding to those in Embodiment 2 are referred to using the same reference numerals as in Embodiment 2. For simplicity, only the differences from Embodiment 2 will be described below. The difference between Embodiment 3 and Embodiment 2 is that a gasket 12 is installed on the outside of the column hole 71, and the nut 92 abuts against the gasket 23, dispersing the force of the nut 92 on the fixing part 7. By increasing the force-bearing area, the pressure is reduced, thereby reducing the pressure around the column hole 71 of the fixing part and extending the service life of the fixing part 7.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
