Description

Technical Field

[0001] This invention belongs to the field of glass production technology, specifically relating to a U-shaped glass rolling forming system and rolling forming method. Background Technology

[0002] In modern architecture, glass curtain walls are an important architectural element. U-shaped glass curtain walls are one type of glass curtain wall. In addition to their application in curtain wall construction, U-shaped glass is also widely used in interior partitions, landscape walls, lobby background walls, and other architectural applications.

[0003] Currently, U-shaped glass is formed using a rolling method, specifically by pressing molten glass into flat glass strips between rollers, and then folding them into U-shaped glass using a forming machine. Patent CN101643316A discloses a method for producing architectural U-shaped glass using waste glass as raw material. Specifically, the raw material is fed into a furnace and melted, clarified, and homogenized at a temperature of 1400℃-1500℃. After being introduced into a glass forming machine, it is pressed into a strip, and then drawn and folded into a U-shape. The formed U-shaped glass strip is then fed into an annealing furnace and subjected to a gradient cooling process at a speed of 3.8 meters per minute, sequentially at temperatures of 570°C, 560°C, 550°C, 540°C, and 530°C. After cooling to 120°C, it exits the annealing furnace and is then cooled to 45°C by strong air. Finally, it is cut as needed to obtain the architectural profile - U-shaped glass product. However, the patent does not provide specific methods for calendering and bending. Current production relies entirely on the judgment and operation of staff based on years of experience, which has significant limitations.

[0004] In addition, the existing U-shaped glass forming equipment is relatively outdated, with poor stability and low control precision, making it difficult to meet the increased drawing volume, resulting in low actual production efficiency, low yield, and insufficient cooling intensity, leading to a large lateral temperature difference in the glass strip. Summary of the Invention

[0005] In view of the above-mentioned deficiencies of the prior art, the present invention provides a U-shaped glass calendering system and calendering method. The calendering system has high stability and high control precision, can standardize the production process, and can guarantee the drawing amount of U-shaped glass, resulting in high actual production efficiency and high yield.

[0006] The technical solution adopted by this invention to solve its technical problem is:

[0007] A U-shaped glass rolling forming system includes a rolling device, a conveying device, and a shaping device. The rolling device includes a pressure roller component, which includes an upper rolling roller and a lower rolling roller. The upper and lower rolling rollers cooperate to rapidly cool molten glass into a glass strip. The conveying device is located to the right of the lower rolling roller and is used to convey and cool the glass strip. The shaping device is located above the conveying device and includes a forming block component and a shaping roller component.

[0008] Furthermore, the calendering apparatus also includes a pressure control component, which includes a first elevator, a pressure sensor, a connecting frame, and a pressure rod.

The air nozzle of each air grid is aligned with the gap between the corresponding two adjacent auxiliary conveyor rollers. The cooling air blown out by the multiple air grids of each air grid cooling component is used to cool the glass ribbon and provide air cushion support for the glass ribbon.

[0011] Furthermore, the shaping device also includes a top roller assembly located on the right side of the forming block component. The top roller assembly includes two top roller assemblies that are symmetrical about the center line of the glass belt. Multiple top rollers of each top roller assembly are arranged side by side from left to right, and the outer peripheral surface of each top roller is used to abut against the flange of the corresponding side of the glass belt.

[0012] Furthermore, the shaping device also includes a control wheel component located on the right side of the top wheel component. The control wheel component includes two control wheel assemblies symmetrically arranged front and rear relative to the conveying centerline of the glass strip. Each control wheel assembly includes two control wheels arranged side by side. The gap between the two control wheels of each control wheel assembly forms a passage for the glass strip to pass through on the corresponding side flange. The outer peripheral surfaces of the two control wheels of each control wheel assembly are respectively used to abut against the corresponding side of the corresponding side flange of the glass strip.

[0013] Furthermore, the surface in each of the forming blocks that contacts the edge of the corresponding side of the glass strip is a formed curved surface with a smooth transition, and each of the forming blocks can extend and retract back and forth by a first telescopic component; each of the top wheel assemblies includes three top wheels, the leftmost top wheel in each of the top wheel assemblies can extend and retract back and forth by a second telescopic component, and the other two top wheels in each of the top wheel assemblies can extend and retract synchronously by a third telescopic component; the two control wheels in each of the edge control wheel assemblies can extend and retract synchronously by a fourth telescopic component.

[0016] A method for rolling and forming U-shaped glass, using the aforementioned U-shaped glass rolling and forming system, specifically involves: rapidly rolling and cooling molten, viscous glass liquid into a plastic glass strip through the cooperation of the upper and lower rolling rollers; conveying the plastic glass strip through the conveying device and cooling it to a certain temperature; and bending the edge of the cooled glass strip on the corresponding side upwards through each forming block of the forming block component to form a flange, thereby obtaining a brittle, solid U-shaped glass. The outer peripheral surface of the shaping roller abuts against the top surface of the glass strip to achieve shaping of the glass strip.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] The U-shaped glass rolling forming system of the present invention includes a rolling device, a conveying device, and a shaping device. The rolling device includes a pressure roller component, which includes an upper rolling roller and a lower rolling roller.

When using this U-shaped glass rolling forming system to roll and form U-shaped glass, molten, viscous glass is rapidly rolled and cooled into a plastic glass strip by the cooperation of upper and lower rolling rollers.

Detailed Implementation

[0026] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. These embodiments are for illustrative purposes only and are not intended to limit the scope of the invention.

Therefore, they should not be construed as limitations on 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.

[0028] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0029] Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0030] like Figure 1 and Figure 2 As shown, a U-shaped glass rolling forming system includes a rolling device, a conveying device, and a shaping device. The rolling device includes a pressure roller component, which includes an upper rolling roller 101 and a lower rolling roller 201. The upper rolling roller 101 and the lower rolling roller 201 cooperate to roll and rapidly cool the molten glass into a glass strip. The conveying device is located to the right of the lower rolling roller 201 and is used to convey and cool the glass strip. The shaping device is located above the conveying device and includes a forming block component and a shaping roller 4 component. The forming block component includes two forming blocks 3 symmetrically positioned front and rear relative to the conveying centerline of the glass strip. Each forming block 3 is used to bend the edge of the corresponding side of the glass strip upward to form a flange. The shaping roller 4 component includes a shaping roller 4 whose outer peripheral surface abuts against the top surface of the glass strip.

[0031] When U-shaped glass is rolled and formed using this U-shaped glass rolling system, molten, viscous glass is rapidly rolled and cooled into a plastic glass strip by the upper rolling roller 101 and the lower rolling roller 201. The plastic glass strip is then conveyed and cooled to a certain temperature by a conveying device. Each forming block 3 of the forming block component bends the edge of the cooled glass strip on the corresponding side upward to form a flange, resulting in a brittle, solid U-shaped glass. The outer circumferential surface of the shaping roller 4 abuts against the top surface of the glass strip to shape it. Therefore, this U-shaped glass rolling and forming system, through the cooperation of the rolling device, conveying device, and shaping device, can achieve the rolling and forming of U-shaped glass. This rolling and forming system has high stability and high control precision, can standardize the production process, can guarantee the drawing amount of U-shaped glass, has high actual production efficiency and high yield, and can reduce production costs.

[0032] The upper calendering roll 101 and the lower calendering roll 201 are driven by corresponding transmission components 17. The specific structure of the transmission component 17 is prior art and will not be described in detail here.

[0033] In one embodiment, the calendering apparatus further includes a pressure control component, such as... Figure 1 As shown, the pressure control component includes a first elevator, a pressure sensor 6, a connecting frame 7, and a pressure rod 8. The detection end of the pressure sensor 6 is fixedly connected to the upper end of the first lifting screw 5 of the first elevator. The housing of the pressure sensor 6 is hinged to the right end of the connecting frame 7. The left end of the connecting frame 7 is hinged to the upper end of the pressure rod 8. The lower end of the pressure rod 8 abuts against the upper end of the upper calendering roller 101.

[0034] By setting up the pressure control component, pressure can be applied to the upper calendering roller 101 and the magnitude of the applied pressure can be controlled. The pressure sensor 6 detects the pressure on the upper calendering roller 101 by detecting the output pressure of the first lifting screw 5, so as to stabilize the thickness difference of the glass strip.

[0035] The pressure sensor 6 is a high-temperature pressure sensor; the pressure control component applies up to 8T of pressure to the upper calendering roller 101; the first elevator also includes a first lifting handwheel and a first input shaft, the first lifting handwheel is fixedly connected to the first input shaft, and the first input shaft is connected to the first lifting screw 5 through a worm gear structure.

[0036] By rotating the first lifting handwheel, the first input shaft rotates, and the first input shaft drives the first lifting screw 5 to rise and fall through the worm gear structure. The housing of the pressure sensor 6 rises and falls along with the first lifting screw 5. The right end of the connecting frame 7 rises and falls along with the housing of the pressure sensor 6. When the right end of the connecting frame 7 rises, the left end falls, and when the right end of the connecting frame 7 falls, the left end rises. The pressure rod 8 rises and falls along with the left end of the connecting frame 7 to apply corresponding pressure to the upper calendering roller 101.

[0037] In one embodiment,

[0038] like Figure 1 and Figure 2 As shown, the conveying device includes a secondary conveying roller assembly and a main conveying roller assembly. The secondary conveying roller assembly is located to the right of the lower calendering roller 201 and includes multiple secondary conveying rollers 9 arranged side by side from left to right with their tops at progressively lower horizontal heights. The main conveying roller assembly is located to the right of the secondary conveying roller assembly and includes multiple main conveying rollers 10 arranged side by side from left to right with their tops at the same horizontal height. The shaping device is located above the main conveying roller assembly.

[0039] Among them, such as Figure 1As shown, the upper calendering roll 101 has an upper water core 102 inside its cavity. The gap between the roll wall of the upper calendering roll 101 and the upper water core 102 forms an upper cooling water cavity 103 for cooling water to flow through, thus achieving direct water cooling of the upper calendering roll 101. The lower calendering roll 201 has a lower water core 202 inside its cavity. The gap between the roll wall of the lower calendering roll 201 and the lower water core 202 forms a lower cooling water cavity 203 for cooling water to flow through, thus achieving direct water cooling of the lower calendering roll 201. Each auxiliary conveying roll 9 is equipped with an auxiliary cooling water pipe for cooling water to flow through, thus achieving indirect water cooling of the auxiliary conveying roll 9. Each main conveying roll 10 is equipped with a cooling water pipe for cooling water to flow through. The main cooling water pipe indirectly cools the main conveyor roller 10. A cooling fan is arranged below the auxiliary conveyor roller assembly. The cooling fan includes two cooling fan components. One cooling fan component is arranged below the gap between two adjacent auxiliary conveyor rollers 9. Each cooling fan component includes multiple cooling fan assemblies arranged side by side from front to back. Each cooling fan assembly includes a cooling fan 11 and a damper on the cooling fan 11. The nozzle of each cooling fan 11 is aligned with the gap between two adjacent auxiliary conveyor rollers 9. The cooling air blown out by the multiple cooling fans 11 of each cooling fan component is used to cool the glass ribbon and provide air cushion support for the glass ribbon.

[0040] The upper cooling water chamber 103 enables direct water cooling of the upper calendering roll 101, and the lower cooling water chamber 203 enables direct water cooling of the lower calendering roll 201. Therefore, the cooling intensity of the upper and lower calendering rolls 101 and 201 is high, thus enabling rapid cooling and forming of the glass ribbon. Furthermore, the auxiliary cooling water pipe enables indirect water cooling of the auxiliary conveying roll 9, and the main cooling water pipe enables indirect water cooling of the main conveying roll 10, thereby reducing the impact on the conveyed glass ribbon. The cooling efficiency is high; the cooling air blown out by the nozzles of the multiple air grilles 11 of each air grille cooling component can perform lateral air cooling on the glass strip, so the cooling intensity of the glass strip is large. During the cooling process of the glass strip, it can compensate for the lateral temperature difference of the glass strip, thereby reducing the lateral temperature difference of the glass strip. In addition, each air grille 11 is equipped with an independent air valve, so the air volume of each air grille 11 is adjustable. Furthermore, the cooling air blown out by the nozzles of the multiple air grilles 11 of each air grille cooling component can also provide air cushion support for the glass strip.

[0041] Among them, such as Figure 1 and Figure 2 As shown, the calendering apparatus also includes a water-cooled support plate 18 located between the lower calendering roll 201 and the auxiliary conveying roll assembly, with cooling water circulating inside the water-cooled support plate 18. The water-cooled support plate 18 serves to support and cool the glass ribbon.

[0042] The calendering device and the auxiliary conveyor roller assembly are located above the first frame 19, and the calendering device and the auxiliary conveyor roller assembly can be raised and lowered as a whole relative to the first frame 19. The main conveyor roller assembly is located above the second frame 20, and can be raised and lowered as a whole relative to the second frame 20.

[0043] In one embodiment,

[0044] The shaping device also includes a top roller assembly located on the right side of the forming block assembly. The top roller assembly includes two top roller assemblies that are symmetrical about the front and rear of the conveying centerline of the glass belt. Multiple top rollers 12 of each top roller assembly are arranged side by side from left to right, and the outer peripheral surface of each top roller 12 is used to abut against the flange of the corresponding side of the glass belt.

[0045] In this way, the multiple top rollers 12 of each top roller assembly can cooperate to prevent the flange on the corresponding side of the formed U-shaped glass from tilting outward.

[0046] The shaping device also includes a control wheel assembly located to the right of the top wheel assembly. The control wheel assembly comprises two control wheel assemblies symmetrically positioned front-to-back relative to the conveying centerline of the glass strip. Each control wheel assembly includes two control wheels 13 arranged side-by-side. The gap between the two control wheels 13 in each control wheel assembly forms a passageway 14 for the glass strip to pass through on the corresponding side flange. (See...) Figure 2 The outer peripheral surfaces of the two control wheels 13 of each control wheel assembly are respectively used to abut against the corresponding side of the corresponding flange of the glass strip.

[0047] In this way, when the formed U-shaped glass is being transported, the flanges on each side of the U-shaped glass pass through the gap between the two control wheels 13 in the corresponding side control wheel assembly, thereby preventing the flanges on both sides of the formed U-shaped glass from developing a wavy deformation.

[0048] Among them, such as Figure 2 As shown, the surface of each forming block 3 that contacts the edge of the corresponding side of the glass strip is a shaped curved surface with a smooth transition. Each forming block 3 can extend and retract back and forth by being driven by the first telescopic component. Each top wheel assembly includes three top wheels 12. The leftmost top wheel 12 in each top wheel assembly can extend and retract back and forth by being driven by the second telescopic component. The other two top wheels 12 in each top wheel assembly can extend and retract back and forth synchronously by being driven by the third telescopic component. The two control wheels 13 in each control wheel assembly can extend and retract back and forth synchronously by being driven by the fourth telescopic component.

[0049] By using two first telescopic components, the front-to-back horizontal distance between the two forming blocks 3 can be adjusted, thus adapting to U-shaped glass forming sizes of different widths. By using two second telescopic components, the front-to-back horizontal distance between the leftmost top wheel 12 of one top wheel assembly and the leftmost top wheel 12 of the other top wheel assembly can be adjusted. By using two third telescopic components, the front-to-back horizontal distance between each of the remaining two top wheels 12 of one top wheel assembly and the corresponding top wheel 12 of the remaining two top wheels 12 of the other top wheel assembly can be adjusted, thus effectively preventing the flange on the corresponding side of the formed U-shaped glass from tilting outward for U-shaped glass of different widths. By using two fourth telescopic components, the front-to-back horizontal distance between the two edge control wheel assemblies can be adjusted, thus effectively preventing the flanges on both sides of the formed U-shaped glass from developing a wavy deformation for U-shaped glass of different widths.

The molding block 3 is fixed to the other end of the first telescopic shaft 2104. Thus, by rotating the first telescopic handwheel 2101, the first screw shaft 2103 rotates, and the molding block 3 extends and retracts relative to the first screw shaft 2103 along with the first telescopic shaft 2104.

[0052] like Figure 1 and Figure 2 As shown, the second telescopic assembly includes a second telescopic handwheel 2201, a second guide bracket 2202, a second screw shaft, a second telescopic shaft 2203, a second bracket 2204, and a second flange shaft.

The two third flange shafts 2306 are arranged side by side, with their upper ends fixedly connected to the third bracket 2305. The other two top wheels 12 in the corresponding side top wheel assembly are rotatably connected to a corresponding third flange shaft 2306 via a third graphite bearing 2307.

[0055] By rotating the third telescopic handwheel 2301, the third screw shaft 2303 rotates, and the third bracket 2305 extends and retracts relative to the third screw shaft 2303 along with the third telescopic shaft 2304. The two third flange shafts 2306 extend and retract along with the third bracket 2305, and the other two top wheels 12 in the corresponding side top wheel assembly extend and retract along with the corresponding third flange shaft 2306.

The two control wheels 13 in the corresponding side control wheel assembly are rotatably connected to a corresponding fourth flange shaft 2406 via a fourth graphite bearing 2407. The front-to-back horizontal distance between the two fourth flange shafts 2406 on the fourth bracket 2405 can be adjusted to accommodate the production of U-shaped glass of different thicknesses.

[0057] By rotating the fourth telescopic handwheel 2401, the fourth screw shaft 2403 rotates, and the fourth bracket 2405 extends and retracts relative to the fourth screw shaft 2403 along with the fourth telescopic shaft 2404. The two fourth flange shafts 2406 extend and retract along with the fourth bracket 2405, and the two control wheels 13 in the corresponding side control wheel assembly extend and retract along with the corresponding fourth flange shaft 2406.

[0058] In one embodiment,

[0059] The axis of the shaping roller 4 is perpendicular to the center line of the glass belt conveyor, and the length of the shaping roller 4 is equal to the front and rear width of the top surface of the glass belt. The shaping roller 4 can be raised and lowered by the second lifting mechanism.

[0060] In this way, the shaping roller 4 can be lifted and lowered by the second elevator to adapt to the production of U-shaped glass of different thicknesses.

[0061] The second elevator includes second lifting components arranged symmetrically front and rear, such as... Figure 1 As shown, the second lifting component includes a second lifting handwheel 2501, a second input shaft, a second lifting screw 2502, and a water-cooled slider 2503. The second lifting handwheel 2501 is fixedly connected to the second input shaft, and the second input shaft is connected to the second lifting screw 2502 through a worm gear structure. The water-cooled slider 2503 is fixedly connected to the lower end of the second lifting screw 2502, and the water-cooled slider 2503 is rotatably connected to the corresponding side shaft head of the shaping roller 4 through a bearing.

[0062] By rotating the second lifting handwheel 2501, the second input shaft is rotated, and the second input shaft drives the second lifting screw 2502 to rise and fall through the worm gear structure. The water-cooled slider 2503 rises and falls along with the second lifting screw 2502, and the shaping roller 4 is driven to rise and fall by the front and rear water-cooled sliders 2503.

[0063] like Figure 6 As shown, the water-cooled slider 2503 has a cooling channel 250301 around its inner circumference. By introducing cooling water into the cooling channel 250301, the bearing installed on the water-cooled slider 2503 can be cooled.

[0064] In one embodiment, the calendering apparatus further includes a roll gap adjustment component, such as... Figure 1 As shown, the roller gap adjustment component includes a third lifting machine and an adjustment frame 15. The upper end of the third lifting screw 16 of the third lifting machine is connected to the upper calendering roller 101 through the adjustment frame 15. The upper calendering roller 101 can be raised and lowered by the drive of the third lifting machine.

[0065] In this way, the upper calendering roller 101 can be raised and lowered by the third lifting mechanism, thereby adjusting the vertical gap between the upper calendering roller 101 and the lower calendering roller 201 to adapt to the rapid cooling forming of glass strips of different thicknesses.

[0066] The third lifting mechanism also includes a third lifting handwheel and a third input shaft. The third lifting handwheel is fixedly connected to the third input shaft, and the third input shaft is connected to the third lifting screw 16 through a worm gear structure.

[0067] By rotating the third lifting handwheel, the third input shaft is rotated, and the third input shaft drives the third lifting screw 16 to rise and fall through the worm gear structure. The upper calendering roller 101 is then raised and lowered through the adjusting frame 15 under the drive of the third lifting screw 16.

[0068] A method for rolling and forming U-shaped glass, using the aforementioned U-shaped glass rolling and forming system, specifically involves: rapidly rolling and cooling molten viscous glass at 1050°C to a plastic glass strip at 800°C using an upper rolling roller 101 and a lower rolling roller 201; conveying the plastic glass strip through a conveying device and gradually cooling it to 700°C; bending the edge of the glass strip cooled to 700°C on the corresponding side upwards through each forming block 3 of the forming block component to form a flange, thereby obtaining a brittle solid U-shaped glass; wherein the outer peripheral surface of the shaping roller 4 abuts against the top surface of the glass strip to shape the glass strip; and the U-shaped glass is further conveyed by the conveying device and cooled to 600°C before being sent to an annealing furnace.

[0069] The U-shaped glass rolling forming system of the present invention can meet the continuous production of drawing capacity of 20t / d-80t / d.

[0070] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
