Abstract
Description
Technical Field
[0001] This invention relates to the field of curtain wall glass manufacturing technology, specifically a manufacturing process for scratch-resistant, high-transmittance, low-emissivity, and energy-saving curtain wall glass. Background Technology
[0002] The foundation of curtain wall glass is float glass sheet. Through a "combination process" of tempering, coating, lamination, and insulated assembly, it is made into the external protective tempered glass required for buildings. Among them, the tempering process is the initial process in the production of curtain wall glass. It heats the glass sheet to near its softening point and then cools it rapidly, so that compressive stress is formed on the glass surface and tensile stress is formed inside, thereby increasing the strength. Therefore, the tempering process is an important production process in the production of curtain wall glass.
[0003] For example, Chinese patent CN114315109A discloses a high-speed centrifugal pressing molding method for manufacturing curtain wall glass. This method uses the centrifugal force generated by high-speed rotation to shape flat glass with high-temperature plasticity into curved glass. The centrifugal force is controllable and acts evenly on every point on the glass, resulting in uniform stress, uniform glass thickness, and natural curvature.
[0004] However, existing methods of forming curved glass by applying centrifugal force have a tendency to cause the upper part of the glass to sag when heated to near its softening point due to its own gravity. This results in the upper part of the glass tending to sag under gravity during the centrifugal forming process, making it unable to fit tightly with the curved support components and causing uneven deformation of the curved glass surface. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides a manufacturing process for scratch-resistant, high-transmittance, low-emissivity, energy-saving curtain wall glass, solving the problems mentioned in the background technology.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a process for manufacturing scratch-resistant, high-transparency, low-emissivity, energy-saving curtain wall glass, comprising the following steps: Step 1, feeding the cut glass into a straight roller conveyor; Step 2, reciprocatingly feeding the glass in the straight roller conveyor, using a heating source located on the conveyor path to heat the glass to near its softening point; Step 3, adjusting the shape of the roller conveyor to match the desired shape of the tempered glass, and reciprocatingly feeding and shaping the softened glass; Step 4, after the glass shaping is completed, rapidly cooling the glass using high-pressure air cooling to achieve the tempered properties of the glass.
[0007] Furthermore, the roller conveyor includes a roller conveyor structure, with a track-changing assembly for adjusting the shape of the roller conveyor located below the roller conveyor structure, and a transmission assembly for providing its roller conveying operation located on one side of the roller conveyor path; the roller conveyor structure is arranged in a split manner, with the roller conveyor structure in the central part set to a fixed state, so that the roller conveyor structures on both sides can adjust their shape with the roller conveyor structure in the central part as the center line.
[0008] Furthermore, the roller conveyor structure includes: a support roller; and a limiting roller, which is disposed above the support roller and can move toward the support roller.
[0009] Furthermore, the track-changing assembly is used to drive the two side roller conveyor structures to adjust the roller conveyor shape with the central roller conveyor structure as the center line. The track-changing assembly includes: a track frame, located below the conveyor path of the roller conveyor structure, wherein at least one set of horizontal tracks is formed on the side wall of the track frame, and two rows of arc-shaped tracks are formed below the horizontal tracks; a top support frame, located inside the track frame and fixedly connected to the roller conveyor structure, wherein at least one end of the top support frame is provided with a guide slip, which can slide between the horizontal track and the arc-shaped track. When the guide slip slides along the horizontal track, it drives the two side roller conveyor structures to adjust their horizontal state with the central roller conveyor structure as the center zero point, and when the guide slip slides along the arc-shaped track, it drives the two side roller conveyor structures to adjust their arc-shaped state with the central roller conveyor structure as the tangent point.
[0010] Furthermore, the track-changing assembly also includes a stop structure for limiting the sliding of the guide slide buckle. The stop structure includes: a rotating shaft located on one side of the center of the horizontal track, and having two sets; and two stop rods, each set on one of the rotating shafts. The stop rods can rotate in opposite directions in response to the rotation of the rotating shafts, so that when the stop rods are horizontally unfolded, they provide the limit required for the guide slide buckle to slide along the horizontal track, and when folded in opposite directions, they provide the clearance required for the guide slide buckle to slide along the arc track.
[0011] Furthermore, the arc-shaped track is arranged in a split manner on the sliding trajectory of the horizontal track and is connected to the horizontal track. The connection part between the arc-shaped track and the horizontal track forms a chamfered opening, providing the channel required for the guide slide buckle to change track.
[0012] Furthermore, each set of support rollers is provided with a third bevel gear at one end, and adjacent third bevel gears are arranged in opposite directions; the transmission assembly is arranged separately between adjacent third bevel gears, and is used to drive the synchronous roller conveying operation during the track changing process of the roller conveyor structure. The transmission assembly includes: a first bevel gear, which is arranged on one side of the center of the distance between adjacent support rollers and can mesh with the third bevel gear on the corresponding support roller; and a second bevel gear, which is arranged on the other side of the center of the distance between adjacent support rollers and can mesh with the third bevel gear on the adjacent corresponding support roller.
[0013] Furthermore, the transmission assembly also includes: a drive shaft fixedly connected to the central shaft of the first bevel gear; a splined bushing fixedly connected to the central shaft of the second bevel gear and having a splined groove formed therein; a splined shaft slidably installed in the splined groove to provide continuous roller feeding when the horizontal shape of the roller conveyor structure is adjusted; and a universal joint disposed between the drive shaft and the splined shaft to provide continuous roller feeding when the arc shape of the roller conveyor structure is adjusted.
[0014] Furthermore, the heating source includes a heating structure, which is arranged separately between adjacent roller structures for heating the glass on the roller conveyor path. The heating structure includes: a second electromagnetic heating roller, which is arranged between adjacent support rollers; and a first electromagnetic heating roller, which is arranged above the second electromagnetic heating roller and can move closer to the second electromagnetic heating roller.
[0015] Furthermore, the heating structure also includes spring seats located on both sides of the first electromagnetic heating roller and the second electromagnetic heating roller, providing synchronous track-changing movement of the heating structure when the shape of the roller conveyor changes.
[0016] The present invention has the following beneficial effects:
[0017] (1) The scratch-resistant, high-transparency, low-emissivity, energy-saving curtain wall glass manufacturing process uses the shape adjustment of the roller structure by the track-changing component and the real-time drive of the transmission component during the shape adjustment process of the roller structure. This ensures that the glass sheet is always in the roller feeding and shaping state when it is heated to near the softening point and during the subsequent shaping process. The real-time shaping adjustment of various parts of the glass sheet maintains the uniformity and consistency of the force during the heating and shaping of the glass sheet, and ensures the accuracy and smoothness of the tempering and forming of the glass sheet.
[0018] (2) The process for preparing scratch-resistant, high-transparency, low-emissivity, energy-saving curtain wall glass involves adjusting the shape of the roller structure through the action of the track-changing component. First, the roller structure is kept straight, and the glass sheet is repeatedly heated by the roller feeding. The glass sheet is heated to near its softening point. Then, the shape of the roller structure is adjusted to match the required tempered glass shape according to the tempering shape of the glass sheet. This allows the change in the shape of the roller structure to be used for both the molding and tempering of straight glass and the molding and tempering of curved glass, making the preparation and use more flexible.
[0019] (3) The scratch-resistant, high-transparency, low-emissivity, energy-saving curtain wall glass manufacturing process uses a roller conveyor structure to repeatedly roll the glass sheet in real time, so that after heating and shaping, it can be cooled in a dynamic rolling state, so that all parts of the glass sheet can come into contact with the cold air in time, ensuring the uniformity of the tempering and cooling of the glass sheet. When it loses its plasticity after cooling, it can be autonomously transported out along the roller conveyor structure, avoiding deformation of the glass sheet by external force when it is taken out, and facilitating the picking of the glass sheet.
[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0044] 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.
[0045] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.
[0046] The following is based on Figures 1-16 This invention describes a process for manufacturing scratch-resistant, high-transmittance, low-emissivity, energy-saving curtain wall glass according to an embodiment of the present invention.
[0047] like Figure 1 As shown, a manufacturing process for scratch-resistant, high-transmittance, low-emissivity, energy-saving curtain wall glass includes the following steps:
[0048] Step 1: Feed the cut glass into a straight roller conveyor.
[0049] Step 2: After the glass is completely rolled into the roller conveyor, control the roller conveyor to roll in both the forward and reverse directions, so that the glass is rolled back and forth in the straight roller conveyor. At the same time, use the heating source set on the conveyor path to uniformly heat the dynamically rolled glass to near the softening point.
[0050] Step 3: After the glass is heated to near its softening point, adjust the shape of the roller conveyor to match the desired shape of the tempered glass. If the glass is flat, maintain the straight roller conveyor. If the glass is curved, adjust the shape of the roller conveyor's trajectory to make the roller conveyor's trajectory change to a curved state, adjust the glass from flat to curved, and make the roller conveyor reciprocate to shape the softened glass, so that the glass is kept in a dynamic rolling and shaping state.
[0051] Step four: After the glass molding is completed, the glass is rapidly cooled by high-pressure air cooling to form the tempered properties of the glass. After the glass loses its molding, it is sent out from the inner roller of the roller conveyor.
[0052] like Figures 2-3 , Figures 8-9As shown, to achieve glass conveying within the roller conveyor, the roller conveyor includes a roller conveyor structure 500, which in turn includes a support roller 505 and a limiting roller 506 positioned above the support roller 505. The support roller 505 and the limiting roller 506 are supported by a support frame 501. The support roller 505 is rotatably mounted on the support frame 501, and the limiting roller 506 is slidably mounted on the support frame 501. A first lifting slide 503 is provided on the support frame 501 to support the sliding of the limiting roller 506. A first lead screw 504, rotatably mounted on the upper end of the support frame 501 and connected to the first lifting slide 503, is used to lift and lower the first lifting slide 503 by the threaded movement of the first lead screw 504. This causes the limiting roller 506 to move closer to or further away from the support roller 505, thus forming a variable conveying track between the support roller 505 and the limiting roller 506, allowing the conveying track to be adapted to the glass thickness.
[0053] Furthermore, the roller conveyor structure 500 also includes a first gear 507 located at one end of the support roller 505 and a second gear 508 located at one end of the limiting roller 506, ensuring that the first gear 507 and the second gear 508 are always meshed. By utilizing the meshing of the first gear 507 and the second gear 508, a counter-rolling state is formed between the support roller 505 and the limiting roller 506. The support roller 505 acts as a roller support at the bottom of the glass, and the limiting roller 506 acts as a roller limit at the top of the glass, thus realizing the roller conveying of the glass within the roller conveyor structure 500. (The limiting roller 506 mainly serves as a limiting guide for the glass. It only needs to be slightly in contact with the upper surface of the glass. The pressure acting on the upper surface of the glass is less than the weight of the glass acting on the support roller 505, and will not cause indentations on the glass. Then, by utilizing the main roller conveying thrust of multiple sets of support rollers 505 acting on the bottom of the glass and the auxiliary limiting guide thrust of multiple sets of limiting rollers 506 acting on the upper part of the glass, the reciprocating roller conveying of the glass within the roller conveyor can be formed.)
[0054] like Figures 2-7 , Figures 11-14 As shown, in order to achieve the shaping adjustment of the heated glass by the roller conveyor structure 500, the roller conveyor structure 500 is arranged in a split manner, and the roller conveyor structure 500 in the center is set to a fixed state, so that the roller conveyor structures 500 on both sides adjust the shape of the roller conveyor with the roller conveyor structure 500 in the center as the center line.
[0055] Specifically: A guide adjustment assembly 100 for adjusting the shape of the roller conveyor is provided below the roller conveyor structure 500. The guide adjustment assembly 100 is used to drive the roller conveyor structures 500 on both sides to adjust the conveyor shape with the central roller conveyor structure 500 as the center line. The guide adjustment assembly 100 includes a track frame 101 located below the conveying path of the roller conveyor structure 500. Two sets of horizontal tracks 104 are formed on the side wall of the track frame 101, and two rows of arc-shaped tracks 102 are formed below each set of horizontal tracks 104. At the same time, a top support frame 106 is provided inside the track frame 101. The top support frame 106 is fixedly connected to the roller conveyor structure 500. Guide latches 108 are provided at both ends of the top support frame 106. The guide latches 108 can slide between the horizontal track 104 and the arc track 102. When the guide latches 108 slide along the horizontal track 104, they drive the roller conveyor structures 500 on both sides to adjust their horizontal state with the central roller conveyor structure 500 as the zero point. Similarly, when the guide latches 108 slide along the arc track 102, they drive the roller conveyor structures 500 on both sides to adjust their arc state with the central roller conveyor structure 500 as the tangent point. More specifically:
[0056] The arc-shaped track 102 is separately arranged on the sliding track of the horizontal track 104 and is connected to the horizontal track 104. The connection point between the arc-shaped track 102 and the horizontal track 104 forms a chamfered opening, providing a channel for the guide slider 108 to change track. When the guide slider 108 slides along the horizontal track 104, it can play a horizontal guiding role, allowing the roller conveyor structure 500 to have an adjustable horizontal shape, forming a flat roller conveying state, which acts on the flat roller conveying heating of the glass and the horizontal shaping of the heated flat glass (such as...). Figure 11 As shown), when the guide latch 108 slides into the arc-shaped track 102 along the chamfered opening, it can play an arc-shaped guiding role, so that the roller conveyor structure 500 has an adjustable arc shape, forming an arc-shaped roller conveying state, which is used to adjust the arc-shaped shaping of the heated glass (such as...). Figures 12-13 As shown), this allows the heated glass to gradually change from a flat state to a curved state, and by adjusting its curved state, different curved trajectories at different angles can be generated to adapt to the shaping of different curved glass surfaces (such as...). Figure 14 As shown in a, b, and c, the glass heated to near its softening point is kept in a flat, roller-fed state, as... Figure 14 As shown in a, when the tempered glass is flat, the roller conveyor structure 500 can be continuously maintained in a straight roller feeding state, and the flat glass can be continuously fed in a straight roller feeding state to reciprocate and shape the flat glass, thereby shaping, cooling and tempering the flat glass. Figure 14As shown in b and c, when the glass is tempered and has an arc shape, the roller structure 500 can be controlled to gradually transform into an arc shape to form the required shape of the arc glass. At the same time, the arc glass is continuously fed in an arc-shaped roller feeding state to reciprocate and mold the arc glass, thereby performing the molding, cooling and tempering of the arc glass.
[0057] It should be noted that, as Figures 4-5 As shown, a central frame 105 is provided inside the track frame 101 for fixing and supporting the central roller structure 500, so that the top support frame 106 is divided into two rows with the central frame 105 as the center for track adjustment, and the shape of the roller structure 500 is changed during the track adjustment process.
[0058] As a further embodiment, multiple rows of electric push rods 107 are arranged symmetrically in pairs within the track frame 101, and two opposing sets of electric push rods 107 are respectively connected to the top support frames 106 arranged on both sides (e.g., Figures 4-5 As shown), the electric push rod 107 can be used as a drive source to adjust the horizontal shape and arc shape of the roller conveyor structure 500. When heating glass of different thicknesses, the horizontal spacing between adjacent roller conveyor structures 500 is pre-adjusted (the spacing between rollers changes exponentially with the thickness of the glass to maintain the uniformity of energy transfer during glass heating and cooling, avoiding excessively dense rollers that would affect energy transfer; furthermore, since most rollers use quartz glass rollers, their manufacturing cost is high, and excessively dense rollers would also increase costs and make subsequent maintenance difficult). At this time, the guide slide 108 is controlled to slide along the horizontal track 104, playing a horizontal guiding role. Then, the electric push rod 107 acts on the telescopic thrust of the top support frame 106, converting the telescopic force into a horizontal force, pushing the guide slide 108 to slide along the horizontal track 104 (as shown). Figure 6 As shown), the horizontal shape of the roller conveyor structures 500 on both sides is adjusted with the central roller conveyor structure 500 as the zero point, so that the overall spacing of the roller conveyor structures 500 changes, adapting to the roller conveying work of glass of different thicknesses. Furthermore, when it is necessary to adjust the roller conveyor structure 500 to an arc shape later, the guide latch 108 is controlled to slide along the arc track 102, providing arc-shaped guidance. The telescopic thrust of the electric push rod 107 acting on the top support frame 106 can also be converted into arc-shaped tension, pulling the guide latch 108 to slide along the arc track 102 (as shown). Figure 7 As shown, the roller conveyor structures 500 on both sides are adjusted to an arc shape with the central roller conveyor structure 500 as the center point, so that the overall state of the roller conveyor structure 500 is transformed into an arc shape.
[0059] Furthermore, such as Figures 6-7As shown, to enable the guide slide 108 to slide along the arc track 102 and the horizontal track 104, the track-changing assembly 100 further includes a stop bar structure 103 for limiting the sliding of the guide slide 108. The stop bar structure 103 includes two sets of rotating shafts 1031 located on one side of the center of the horizontal track 104, and two sets of stop bars 1032 are provided on each of the two sets of rotating shafts 1031. Two sets of meshing third gears 1033 are also provided on the central shafts of the two sets of rotating shafts 1031, forming opposing driving forces acting on the two sets of rotating shafts 1031. A second motor 1034 is then installed on the track frame 101, and the second motor 1034 is connected to one of the sets of rotating shafts 1031 via a second transmission belt 1035. The second motor 1034 is used as... The drive source drives two sets of rotating shafts 1031 to rotate in opposite directions, and controls two sets of baffles 1032 to deflect in opposite directions. When the baffles 1032 are horizontally unfolded, they are flush with the horizontal track 104, providing the limit required for the guide slide 108 to slide along the horizontal track 104. This allows the roller conveyor structure 500 to have the ability to change its horizontal shape. When the baffles 1032 are folded in opposite directions and offset from the arc track 102, they provide the clearance required for the guide slide 108 to slide along the arc track 102, allowing the roller conveyor structure 500 to have the ability to change its arc shape. After the guide slide 108 is adjusted by sliding along the horizontal track 104, the guide slide 108 is always located at the chamfered opening of the horizontal track 104 and the arc track 102, so that the guide slide 108 can slide into the arc track 102 later.
[0060] like Figures 2-3 , Figures 12-13 , Figures 15-16 As shown, to achieve real-time driving during the shape adjustment process of the roller conveyor structure 500, a third bevel gear 502 is provided at one end of each set of support rollers 505, and adjacent third bevel gears 502 are arranged in positive and negative directions. A transmission assembly 400 for driving the third bevel gears 502 is provided on one side of the roller conveyor structure 500's roller feeding path. The transmission assembly 400 is separately arranged between adjacent third bevel gears 502, used to drive the synchronous roller feeding operation of the roller conveyor structure 500 during track changing. Specifically:
[0061] The transmission assembly 400 includes a first bevel gear 403 disposed on one side of the center of the spacing between adjacent support rollers 505 and a second bevel gear 407 disposed on the other side of the center of the spacing between adjacent support rollers 505. The first bevel gear 403 and the second bevel gear 407 can mesh with a third bevel gear 502 on the corresponding support roller 505. A first motor 2 is provided in the middle of the track frame 101, and a first transmission belt 3 (e.g., a first motor 2 is provided in the middle of the track frame 101, and a first transmission belt 3 connected to the middle support roller 505 is provided on the output shaft of the first motor 2.) Figures 2-3As shown), the first motor 2 serves as the drive source, and the first transmission belt 3 acts on the intermediate support roller 505 for roller feeding and transmission, driving the third bevel gear 502 on the intermediate support roller 505 to rotate. The meshing of the third bevel gear 502 with the first bevel gear 403 and the second bevel gear 407 drives the third bevel gears 502 on other support rollers 505 to rotate. (The driving force generated by the first bevel gear 403 and the second bevel gear 407 is transmitted to the two adjacent sets of third bevel gears 502 by setting the two adjacent sets of third bevel gears 502 as positive...) The reverse setting can generate a driving force acting in the same direction on the two adjacent sets of third bevel gears 502, so as to drive the adjacent support rollers 505 to rotate in the same direction. Then, it drives the split-arranged support rollers 505 to rotate in the same direction. Furthermore, the operation of the support rollers 505 can drive the limit rollers 506 to rotate in the opposite direction, forming a counter-rolling state between the support rollers 505 and the limit rollers 506, which acts on the glass. In addition, by setting the first motor 2 as a forward and reverse motor, the roller conveyor structure 500 has forward and reverse rolling capabilities, and repeatedly rolls the glass in the roller conveyor.
[0062] As a further embodiment, the transmission assembly 400 also includes a drive shaft 402 fixed to the central shaft of the first bevel gear 403 and a splined bushing 406 fixed to the central shaft of the second bevel gear 407. The drive shaft 402 and the splined bushing 406 are rotatably mounted and limited by a support base 401. By mounting the support base 401 on the support frame 501, the first bevel gear 403, the second bevel gear 407 and the third bevel gear 502 are provided in real time when the shape of the roller conveyor structure 500 changes. Furthermore, a universal joint 404 is provided between the drive shaft 402 and the splined shaft 405. Utilizing the universal transmission characteristics of the universal joint 404, the universal joint 404 provides deformation when the roller conveyor structure 500 undergoes arc deformation, and can always provide integrated transmission between the drive shaft 402 and the splined bushing 406, forming an integrated transmission between the first bevel gear 403 and the second bevel gear 407, which acts on the continuous roller conveying when the arc shape of the roller conveyor structure 500 is adjusted.
[0063] Furthermore, a spline groove is formed inside the spline bushing 406, and a spline shaft 405 is slidably installed in the spline groove. The other end of the spline shaft 405 is connected to a universal joint 404 to form a sliding transmission state, so that the roller conveyor structure 500 can always provide continuous roller feeding when the horizontal shape is adjusted.
[0064] like Figures 8-10As shown, the heating source includes a heating structure 600, which is arranged separately between adjacent roller conveyor structures 500 for heating the glass on the roller conveyor path. The heating structure 600 includes a second electromagnetic heating roller 606 disposed between adjacent support rollers 505 and a first electromagnetic heating roller 605 disposed above the second electromagnetic heating roller 606. Fixing frames 601 are provided on both sides of the first electromagnetic heating roller 605 and the second electromagnetic heating roller 606, respectively supporting the first electromagnetic heating roller 605 and the second electromagnetic heating roller 606, and the fixing frames 601 support the first electromagnetic heating roller 605 and the second electromagnetic heating roller 606. A second lifting slide 603 is slidably provided, so that the first electromagnetic heating roller 605 is installed on the second lifting slide 603. A second lead screw 604 connected to the second lifting slide 603 is rotatably installed above the fixed frame 601. The second lifting slide 603 is driven to move up and down by the thread of the second lead screw 604, pushing the first electromagnetic heating roller 605 closer to or away from the second electromagnetic heating roller 606, so that a variable heating channel is formed between the first electromagnetic heating roller 605 and the second electromagnetic heating roller 606 to adapt to the heating of glass of different thicknesses.
[0065] It should be noted that a certain gap is reserved between the second electromagnetic heating roller 606 and the upper roller surface of the support roller 505 to form a heat transfer channel when the electromagnetic heating roller is heating in non-contact mode. This channel can also be used as an adjustment gap for the first electromagnetic heating roller 605, so that when the heating structure 600 is faced with glass of different thicknesses, the first electromagnetic heating roller 605, the second electromagnetic heating roller 606 and the upper and lower surfaces of the glass always maintain the same heat transfer channel, so as to carry out uniform heat transfer.
[0066] As a further embodiment, the heating structure 600 also includes spring seats 602 disposed on both sides of the fixed frame 601, and the spring seats 602 on both sides are respectively fixed to the adjacent support frame 501. When the horizontal shape of the roller conveyor structure 500 changes, the spring seats 602 can horizontally elastically extend and retract to maintain the horizontal heating state of the two sets of electromagnetic heating rollers. When the arc shape of the roller conveyor structure 500 changes, the spring seats 602 can elastically bend and extend and retract, driving the two sets of electromagnetic heating rollers to synchronously arc-shaped deflection, so that the heating structure 600 has the ability to synchronously change track and always operates in the middle of the two adjacent sets of roller conveyor structures 500.
[0067] In addition to the above, after the glass is heated and shaped, the roller conveyor structure 500 is used to roll the glass in real time, so that the glass is kept in a dynamic plastic state. At this time, the high-pressure cold air used for glass cooling can fully and timely contact all parts of the glass to carry out uniform cooling of the glass, ensuring the uniformity of the strengthening stress formation when the glass is cooled inside and outside. Furthermore, after the glass loses its plasticity after cooling, the roller conveyor structure 500 can be used to directly roll out the strengthened glass, which is convenient for glass loading and unloading.
