Description

Technical Field

[0001] The invention relates to the technical field of glass tempering, in particular to a glass tempering curved roller structure with reliable and stable molding. Background Art

[0002] With the continuous development of the construction market, the demand for glass has become more diverse. Currently, the market demand for bent and tempered glass is increasing, especially for large-format bent and tempered glass. Existing bent and tempered glass production lines generally consist of a loading and unloading table, a heating system, a bending section, an air supply system, and an electrical control system. They are primarily suitable for tempering bent glass in applications such as construction, automobiles, home appliances, furniture, and bathroom fixtures.

[0003] After the original glass sheet is positioned on the placement table, it enters the heating furnace and is heated to the appropriate tempering temperature. The glass then flows under its own weight onto the conveyor rollers into the bending and forming equipment, where it is lifted and curved, and then swung into shape and tempered. During this lifting and curving process, the upper forming rollers press down to assist in shaping the glass. The glass is then lifted and curved by the lower forming rollers to the desired radius of curvature. Simultaneously, the glass on the lower forming rollers is rolled back and forth with the conveyor rollers, forming the desired shape and tempering it with air. However, this structure can affect the quality of the finished glass due to the dynamic friction of the upper forming rollers during the reciprocating swing. Summary of the Invention

[0004] In response to the above-mentioned defects, the purpose of the present invention is to propose a glass tempering curved upper roller structure with reliable and stable forming, which effectively reduces the dynamic friction between the glass and the upper roller shaft of the upper forming roller, avoids the upper roller shaft from scratching the glass, and improves the quality of the finished glass.

[0005] To achieve this purpose, the present invention adopts the following technical solutions: a glass tempering curved upper roller structure with reliable and stable forming, comprising an upper forming roller, an upper air grid group and a lifting and arcing mechanism, wherein the upper forming roller and the upper air grid group are bent into an arc shape by the lifting and arcing mechanism;

[0006] The upper air grille group includes multiple rows of upper air grilles arranged along the glass conveying direction;

[0007] The upper forming roller comprises a driving mechanism, a transmission shaft and an upper roller assembly, wherein the upper roller assembly is arranged below the upper air grille assembly, a driven wheel is provided at one end of the transmission shaft, and the transmission shaft is connected to the driving mechanism via the driven wheel, and a clutch is provided at the other end of the transmission shaft, and the driving mechanism and the upper roller assembly transmit power via the clutch of the transmission shaft;

[0008] The upper roller group includes a plurality of upper rollers, and the upper rollers are rotatably arranged between two adjacent rows of upper air grilles of the upper air grille group;

[0009] Each of the upper roller shafts is provided with a roller shaft transmission tooth at both ends, and the roller shaft transmission teeth at the same end of each two adjacent upper roller shafts are connected through a transition gear set; the driven wheel of the transmission shaft is also connected to the lower forming roller.

[0010] For example, a protruding shaft is provided at one end of the upper roller shaft located directly above the transmission shaft, and the protruding shaft sleeve is provided with an upper transmission roller sprocket located in the same plane as the clutch, and the upper transmission roller sprocket is transmission-connected to the clutch.

[0011] It is worth noting that the transition gear set includes multiple first transition gears and multiple second transition gears. The roller shaft transmission teeth of each upper roller shaft are meshed and connected with one end of a first transition gear opposite to it above and below, and the other ends of two adjacent first transition gears are meshed and connected through a second transition gear.

[0012] Optionally, the upper forming roller comprises a plurality of upper hinge plates hinged to each other, the upper hinge plates are used to mount an upper roller shaft, and the roller shaft transmission teeth of the upper roller shaft are arranged on the outer side of the upper hinge plates.

[0013] Specifically, the transition gear group includes a plurality of transition hinge plates hinged to each other, a transition hinge plate is arranged between each two adjacent upper hinge plates, two first transition gears and a second transition gear are installed on the outer side of the transition hinge plate, the first transition gear is located below the two second transition gears on the transition hinge plate, and the two first transition gears are meshed and connected through the second transition gear.

[0014] Preferably, the roller shaft transmission teeth, the first transition gear and the second transition gear have the same diameter.

[0015] For example, the tooth width of the first transition gear is greater than the tooth width of the roller shaft transmission teeth, and the tooth width of the first transition gear is also greater than the tooth width of the second transition gear.

[0016] It is worth noting that the lifting and arc forming mechanism is hinged to the upper forming roller, and each of the upper roller shafts is connected to the upper air grid of the corresponding upper air grid group.

[0017] Optionally, the lifting and arc forming mechanism includes an upper hinge and a driving unit located above the upper forming roller, the upper air grid is arranged on the upper hinge plate or the transition hinge plate, and the upper hinge plates corresponding to the upper rollers located at both ends of the upper forming roller are respectively connected to the driving unit through the upper hinge.

[0018] The beneficial effects of the present invention are as follows: the upper roller group of the upper forming roller can rotate synchronously with the lower roller group of the lower forming roller, and the dynamic friction between the glass and the upper roller group of the upper forming roller can be effectively reduced when the glass is rolled back and forth between the upper forming roller and the lower forming roller, thereby avoiding the upper roller group from scratching the glass and improving the quality of the finished glass.

[0019] Before the glass has completely entered the upper roller structure of the glass tempering bend with reliable and stable forming, the lower driving mechanism drives the lower roller group to rotate, driving the glass forward. At this time, the clutch is disconnected, and the upper roller group will not rotate due to the lack of power source. When the glass has completely entered the upper roller structure of the glass tempering bend with reliable and stable forming, the clutch is engaged, and the lower driving mechanism drives the lower roller group to rotate while driving the upper roller group to rotate through the transmission shaft and the clutch arranged at the other end thereof. Since the upper roller group and the lower roller group are both driven by the lower driving mechanism, they rotate synchronously, which can effectively reduce the dynamic friction between the glass and the lower roller group during reciprocating swing roller forming. The lifting and arcing mechanism lifts and bends the lower forming roller, the lower air grid group, the upper forming roller and the upper air grid group into an arc, thereby causing the glass located between the lower forming roller and the upper forming roller to bend. The lower air grid group and the upper air grid group blow cool the glass, and finally obtain a curved glass product.

[0020] After the clutch is engaged, the clutch drives one of the upper roller shafts to rotate, the roller shaft transmission teeth of the upper roller shaft drive the corresponding transition gear set to rotate, and the transition gear set drives the roller shaft transmission teeth of the next upper roller shaft to rotate, thereby realizing the rotation of all the upper roller shafts.

DETAILED DESCRIPTION

[0028] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0029] In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0030] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0031] The following combination Figures 1 to 6 , describing an embodiment of the present invention, a glass tempering curved upper roller structure with reliable and stable forming, comprising an upper forming roller 1, an upper air grid group, and a lifting and arcing mechanism 41, wherein the upper forming roller 1 and the upper air grid group are bent into an arc shape by the lifting and arcing mechanism 41;

[0032] The upper air grille group includes multiple rows of upper air grilles 32 arranged along the glass conveying direction;

[0033] The upper forming roller 1 includes a driving mechanism 11, a transmission shaft 13 and an upper roller assembly. The upper roller assembly is arranged below the upper air grille assembly. A driven wheel 131 is provided at one end of the transmission shaft 13. The transmission shaft 13 is connected to the driving mechanism 11 through the driven wheel 131. A clutch 133 is provided at the other end of the transmission shaft 13. The driving mechanism 11 and the upper roller assembly transmit power through the clutch 133 of the transmission shaft 13.

[0034] The upper roller group includes a plurality of upper rollers 12, and the upper rollers 12 are rotatably arranged between two adjacent rows of upper air grilles 32 of the upper air grille group;

[0035] Each of the upper roller shafts 12 is provided with a roller shaft transmission tooth 121 at both ends, and the roller shaft transmission teeth 121 at the same end of each adjacent two upper roller shafts 12 are connected by a transition gear set; the driven wheel 131 of the transmission shaft 13 is also connected to the lower forming roller 2.

[0036] The glass tempering curved upper roller structure with reliable and stable forming can effectively reduce the dynamic friction between the glass and the upper roller group of the upper forming roller 1 when the glass is roll-formed by reciprocating swing between the upper forming roller 1 and the lower forming roller 1, thereby preventing the upper roller group from scratching the glass and improving the quality of the finished glass.

[0037] Before the glass has completely entered the reliably and stably formed glass tempering curved upper roller structure, the lower driving mechanism 11 drives the lower roller group to rotate, driving the glass forward. At this time, the clutch 133 is disconnected, and the upper roller group will not rotate due to the lack of power source. When the glass has completely entered the reliably and stably formed glass tempering curved upper roller structure, the clutch 133 is engaged, and the lower driving mechanism 11 drives the lower roller group to rotate while driving the upper roller group through the transmission shaft 13 and the clutch 133 provided at the other end thereof. The upper roller group rotates, and since both the upper roller group and the lower roller group are driven by the lower driving mechanism 11, they rotate synchronously, which can effectively reduce the dynamic friction between the glass and the roller during reciprocating swing forming. The lifting and arc forming mechanism 41 lifts and bends the lower forming roller 1, the lower air grid group, the upper forming roller 1 and the upper air grid group into an arc, thereby causing the glass located between the lower forming roller 1 and the upper forming roller 1 to bend. The lower air grid group and the upper air grid group blow cool the glass, and finally obtain a curved glass product.

[0038] When the clutch 133 is engaged, it drives one of the upper rollers 12 to rotate. The roller drive teeth 121 of the upper roller 12 drive the corresponding transition gear set to rotate. The transition gear set then drives the roller drive teeth 121 of the next upper roller 12 to rotate, thereby achieving rotation of all the upper rollers 12. The lower drive mechanism 11 is a conventional structure, preferably a motor; the clutch 133 is a conventional structure, preferably an electromagnetic clutch.

[0039] In some embodiments, such as Figure 3As shown, a protruding shaft 122 is provided at one end of the upper roller shaft 12 located directly above the transmission shaft 13, and the protruding shaft 122 is sleeved with an upper transmission roller sprocket 123 located in the same plane as the clutch 133, and the upper transmission roller sprocket 123 is transmission-connected to the clutch 133.

[0040] When the clutch 133 is engaged, the gear on the outer wall of the clutch 133 rotates along with the transmission shaft 13. The gear on the outer wall of the clutch 133 drives the upper transmission roller sprocket 123 located directly above it to rotate via the upper conveyor belt. The upper transmission roller sprocket 123 drives its corresponding upper roller shaft 12 to rotate, which in turn drives the rotation of the other upper roller shafts 12. The above structure can simply and quickly control the rotation of the upper and lower roller shaft groups by engaging the clutch 133, with only the lower drive mechanism 11 required.

[0041] For example, Figure 4 As shown, the transition gear set includes multiple first transition gears 124 and multiple second transition gears 125. The roller shaft transmission tooth 121 of each upper roller shaft 12 is meshed and connected with one end of a first transition gear 124 opposite to it above and below, and the other ends of two adjacent first transition gears 124 are meshed and connected through a second transition gear 125.

[0042] The first transition gear 124 and the second transition gear 125 are both passively rotated and have no power source themselves. In the gear transmission, the direction of rotation will change once after passing through each gear and turn into reverse rotation. The rotation direction of the roller transmission tooth 121 is forward, and the rotation direction of the first transition gear 124 engaged with the roller transmission tooth 121 is reverse. The steering direction of the second transition gear 125 engaged with the first transition gear 124 is forward, and the rotation direction of the other first transition gear 124 engaged with the second transition gear 125 is reverse. Finally, the rotation directions of the adjacent roller transmission teeth 121 are all forward, and the rotation direction of the upper roller shaft 12 is consistent with the rotation direction of the next adjacent upper roller shaft 12, thereby achieving the purpose of transporting glass.

[0043] It is worth noting that the upper forming roller 1 includes a plurality of upper hinge plates 14 hinged to each other. The upper hinge plates 14 are used to install the upper roller shaft 12 , and the roller shaft transmission teeth 121 of the upper roller shaft 12 are arranged on the outer side of the upper hinge plates 14 .

[0044] When the lifting and arc forming mechanism 41 bends the upper forming roller 1 into an arc, the above structure only needs to lift the upper hinge plate 14 to pull its corresponding upper roller shaft 12, and the rotation of the upper roller shaft 12 will not be affected during the lifting process.

[0045] Alternatively, as Figure 5As shown, the transition gear set includes a plurality of transition hinge plates 15 hinged to each other, a transition hinge plate 15 is arranged between each two adjacent upper hinge plates 14, and two first transition gears 124 and a second transition gear 125 are installed on the outer side of the transition hinge plate 15. On the transition hinge plate 15, the first transition gear 124 is located below the two second transition gears 125, and the two first transition gears 124 are meshed and connected through the second transition gear 125.

[0046] All the upper hinge plates 14 are connected by the transition hinge plates 15. When lifting, only the two ends of the upper forming roller 1 need to be lifted to bend the entire upper forming roller 1. Through the meshing structure of the two first transition gears 124 and the one second transition gear 125, when the upper forming roller 1 is bent into an arc, the two first transition gears 124 always surround the second transition gear 125 and mesh with each other, thereby ensuring that each roller shaft can operate.

[0047] Specifically, the roller shaft transmission gear 121 , the first transition gear 124 , and the second transition gear 125 have the same diameter.

[0048] The above structure can ensure that the rotational speed of two adjacent roller transmission teeth 121 does not change during the transmission process, so that the rotational speed of each upper roller 12 is equal.

[0049] Preferably, the tooth width of the first transition gear 124 is greater than the tooth width of the roller shaft transmission gear 121 , and the tooth width of the first transition gear 124 is also greater than the tooth width of the second transition gear 125 .

[0050] During installation, the roller transmission tooth 121 is arranged on the rear side of the first transition gear 124, and the second transition gear 125 is arranged on the front side of the first transition gear 124. During rotation, the roller transmission tooth 121 can avoid collision with the second transition gear 125.

[0051] In some embodiments, such as Figure 6 As shown, the lifting and arc-forming mechanism 41 is hinged to the upper forming roller 1, and each of the upper roller shafts 12 is connected to the upper air grid 32 of its corresponding upper air grid group.

[0052] The lifting and arcing mechanism 41 pulls the upper forming roller 1 to bend, and the bending of the upper forming roller 1 simultaneously drives the bending of the upper air grille assembly. When the upper forming roller 1 and the upper air grille assembly bend simultaneously, the glass to be bent is formed. Due to the gear connection structure between the roller drive teeth 121 of the upper roller 12 of the upper forming roller 1 and the transition gear set, the roller drive teeth 121 and the transition gear set are always in a meshing state when the upper forming roller 1 is lifted. This can prevent the roller drive teeth 121 and the transition gear set from derailing, thereby preventing the upper roller 12 from stopping.

[0053] For example, Figure 1 As shown, the lifting and arc forming mechanism 41 includes an upper hinge 411 and a driving part 412 located above the upper forming roller 1, the upper air grid 32 is arranged on the upper hinge plate 14 or the transition hinge plate 15, and the upper hinge plates 14 corresponding to the upper rollers 21 at both ends of the upper forming roller 1 are respectively connected to the driving part 412 through the upper hinge 411.

[0054] The driving part 412 rotates to make the upper hinge 411 reeled on the reel of the driving part 412, so that the upper hinge plate 14 connected to the upper hinge 411 is lifted up, and the upper hinge plate 14 drives the corresponding upper roller shaft 12 and upper air grid 32 to be lifted up, and then drives the remaining upper roller shafts 12 and upper air grid 32 to be lifted up through the hinged structure between the upper hinge plate 14 and the transition hinge plate 15. After the lifting is completed, the height of the upper roller shafts 12 at both ends of the upper forming roller 1 is the highest, and the height of the upper roller shaft 12 in the middle of the upper forming roller 1 is the lowest, thereby forming a curved arc structure.
