TECHNICAL FIELD

[0001] The utility model belongs to the curved glass forming technical field, concretely relates to a kind of curved glass forming equipment and production line of rolling type overturning. BACKGROUND

[0002] Continuous hard shaft bending equipment is the bending glass tempering equipment that more is applied in current market, with high production efficiency, the advantages such as the glass quality produced is better.But because ordinary continuous hard shaft bending has great limitation, such as the glass with small radius cannot be normally sheeted, and ordinary continuous hard shaft bending forming section is high and cumbersome, overturning angle is not too large, and overturning process is also relatively dangerous.For example, the glass forming equipment in CN102826742A, the equipment is provided with rotating shaft on input side, and forming mechanism can be rotated around rotating shaft and overturn a certain angle, and then sheeted again.In addition, prior art such as CN207918695U adopts a piece connecting device to realize the connection of sheeting outlet of forming mechanism and lower sheeting table, but curved glass falls on piece connecting device from sheeting outlet of forming mechanism and has greater impact and knock, cannot realize smooth sheeting.But the equipment described in the above two prior arts cannot meet higher market demand, so we propose a new glass bending forming equipment. SUMMARY

[0003] The utility model aims at providing a kind of curved glass forming equipment and production line of rolling type overturning, glass can be horizontally sheeted, and when needing sheeting, overturning forming mechanism overturns by horizontal rolling, overturns to horizontal sheeting position, so that curved glass can be horizontally sheeted, and stably conveyed to next equipment, avoid knock and impact in sheeting process.

The possibility of falling the glass when the glass is formed into a sheet is eliminated, the glass is not damaged, and an additional inclined roller bed connecting device is not required. In addition, the traction constraint of the traction constraint allows the overturning forming mechanism to give a certain downward traction force when rolling forward, so that the overturning forming mechanism closely advances along the rolling guide mechanism, realizes non-sliding rolling overturning, eliminates the unpredictability of the sheet outlet position and the sheet outlet angle caused by sliding, and the rolling overturning process is more stable and effective.

DETAILED DESCRIPTION

[0052] The utility model will be further explained in detail in combination with the drawings and embodiments, but it is not as the basis for any limit of the utility model.

[0053] Embodiment 1

[0054] A rolling overturning curved surface glass forming equipment, including main frame 1, rolling frame 2, overturning forming mechanism 3, rolling driving mechanism 5 and rolling guide mechanism 6.

[0055] The overturning forming mechanism 3 includes lower forming mechanism, and the lower forming mechanism includes lower arc changing mechanism 302 and lower roller 301, and the lower arc changing mechanism 302 can select the chain plate type arc changing mechanism commonly used in the field of pulling arc, and the lower arc changing mechanism 302 is provided with two, is distributed in the both sides of glass conveying direction, is supported on two rolling guide mechanisms 6 respectively, and a plurality of lower rollers 301 are connected with the lower arc changing mechanism 302 at both ends respectively, and after the lower arc changing mechanism 302 is bent into arc, a plurality of lower rollers 301 are fitted to form the support forming surface for glass forming.

[0056] The rolling driving mechanism 5 is arranged on the main frame 1, and is connected with the rolling frame 2 to drive the rolling frame 2 to drive the overturning forming mechanism 3 to horizontally roll and overturn on the rolling guide mechanism 6. When the glass needs to enter the forming equipment, the overturning forming mechanism 3 is bent into an arc, the entering end is at a horizontal entering position, the tangent line of the supporting forming surface is parallel to the horizontal plane, and the glass can be horizontally entered; then the overturning forming mechanism 3 is driven by the rolling driving mechanism 5 to overturn to the outlet side of the forming equipment, until the entering end of the overturning forming mechanism 3 reaches the horizontal entering position, and the tangent line of the supporting forming surface is parallel to the horizontal plane, so that the curved glass can be horizontally entered, and the entering end of the overturning forming mechanism 3 is lifted. In this way, the overturning forming mechanism 3 is switched between the horizontal entering position and the horizontal entering position by the driving of the rolling driving mechanism 5, so that the glass can be horizontally entered, formed and horizontally entered.

[0057] It should be noted that, compared with the flat state, the outer circumferential arc length of the bottom of the lower arc changing mechanism 302 increases after being bent into an arc, and therefore the length of the lower arc changing mechanism 302 in the flat state is less than the length of the rolling guide mechanism 6, so that reliable support of the rolling guide mechanism 6 can be obtained during the overturning and rolling process after the lower arc changing mechanism 302 is bent into an arc.

[0058] Further, in the glass forming process of the glass forming equipment, the overturning forming mechanism 3 is directly placed and supported on the upper surfaces of the two rolling guide mechanisms 6, and stable support is achieved by the self-weight of the overturning forming mechanism 3. However, since the bottom of the lower arc changing mechanism 302 is a steel plate or other metal plate structure, and the rolling guide mechanism 6 is also made of metal material, sliding of the lower arc changing mechanism 302 on the rolling guide mechanism 6 is prone to occur during the overturning and rolling process, so that the entering opening or the exiting opening of the overturning forming mechanism 3 before and after overturning cannot be accurately positioned at the same position, and the connection with the upstream equipment or the downstream equipment is affected. Therefore, in order to further increase the stability during the overturning and rolling process, a traction constraint is arranged on the glass forming equipment, including a first traction constraint 4 and a second traction constraint 7. The first traction constraint 4 and the second traction constraint 7 are arranged below each lower arc changing mechanism 302. The first traction constraint 4 and the second traction constraint 7 have the same structure, and the two ends thereof are a fixed end and a movable end respectively. The fixed end of the first traction constraint 4 is fixed on the main frame 1 or the rolling guide mechanism 6 at the inlet side of the forming equipment, and the movable end of the first traction constraint 4 is connected with the exiting end of the lower arc changing mechanism 302. The fixed end of the second traction constraint 7 is fixed on the main frame 1 or the rolling guide mechanism 6 at the outlet side of the forming equipment, and the movable end of the second traction constraint 7 is connected with the entering end of the lower arc changing mechanism 302.

[0059] Specifically, when the overturning forming mechanism 3 overturns from the horizontal entering position shown in FIG. 6 to the horizontal exiting position shown in FIG. 7, the first traction constraint 4 and the second traction constraint 7 are in a state of being stretched and tensioned, and the first traction constraint 4 and the second traction constraint 7 are in a state of being stretched and tensioned. Figure 2 the horizontal entering position shown in FIG. 6 to the horizontal exiting position shown in FIG. 7, the first traction constraint 4 and the second traction constraint 7 are in a state of being stretched and tensioned, and the first traction constraint 4 and the second traction constraint 7 are in a state of being stretched and tensioned.Figure 3 In the process of the horizontal sheet-out position shown, the movable end of the first traction constraint 4 can pull the outlet end of the lower arc-changing mechanism 302, and in cooperation with the fixed end of the first traction constraint 4, give the lower arc-changing mechanism 302 a certain downward traction force while the roll-over forming mechanism 3 is rolling over, so that the lower arc-changing mechanism 302 can closely advance along the rolling guide mechanism 6, realizing non-sliding roll-over, eliminating the unpredictability of the sheet-out position and the sheet-out angle caused by sliding, and making the roll-over process more stable and effective. When the curved glass is finished with sheet-out, the roll-over forming mechanism 3 is pulled by the first traction constraint 4 to the horizontal sheet-in position shown. Figure 3 In the process of the horizontal sheet-in position shown, the movable end of the first traction constraint 4 can pull the outlet end of the lower arc-changing mechanism 302, and in cooperation with the fixed end of the first traction constraint 4, give the lower arc-changing mechanism 302 a certain downward traction force while the roll-over forming mechanism 3 is rolling over, so that the lower arc-changing mechanism 302 can closely advance along the rolling guide mechanism 6, realizing non-sliding roll-over, eliminating the unpredictability of the sheet-out position and the sheet-out angle caused by sliding, and making the roll-over process more stable and effective. When the curved glass is finished with sheet-out, the roll-over forming mechanism 3 is pulled by the first traction constraint 4 to the horizontal sheet-in position shown. Figure 2 In the process of the horizontal sheet-in position shown, the movable end of the first traction constraint 4 can pull the outlet end of the lower arc-changing mechanism 302, and in cooperation with the fixed end of the first traction constraint 4, give the lower arc-changing mechanism 302 a certain downward traction force while the roll-over forming mechanism 3 is rolling over, so that the lower arc-changing mechanism 302 can closely advance along the rolling guide mechanism 6, realizing non-sliding roll-over, eliminating the unpredictability of the sheet-out position and the sheet-out angle caused by sliding, and making the roll-over process more stable and effective. When the curved glass is finished with sheet-out, the roll-over forming mechanism 3 is pulled by the first traction constraint 4 to the horizontal sheet-in position shown.

[0060] In the process of the horizontal sheet-in position shown, the movable end of the first traction constraint 4 can pull the outlet end of the lower arc-changing mechanism 302, and in cooperation with the fixed end of the first traction constraint 4, give the lower arc-changing mechanism 302 a certain downward traction force while the roll-over forming mechanism 3 is rolling over, so that the lower arc-changing mechanism 302 can closely advance along the rolling guide mechanism 6, realizing non-sliding roll-over, eliminating the unpredictability of the sheet-out position and the sheet-out angle caused by sliding, and making the roll-over process more stable and effective. When the curved glass is finished with sheet-out, the roll-over forming mechanism 3 is pulled by the first traction constraint 4 to the horizontal sheet-in position shown.

[0061] The rolling guide mechanism, the rolling frame, the rolling drive mechanism and the arc-changing drive mechanism used in the embodiment will be described below.

[0062] Alternatively, the rolling frame 2 comprises support arms 201 and a roll-over shaft 202, the lower end of the support arm 201 is fixedly connected to the outer side of the end of the lower arc-changing mechanism 302, and each end of the lower arc-changing mechanism 302 is connected to one support arm 201, the upper ends of the two support arms 201 are obliquely intersected so as to be connected to the end of the roll-over shaft 202. A support rod is further connected between the two support arms 201 connected to the two lower arc-changing mechanisms 302 and having the same oblique direction, so as to enhance the strength of the rolling frame 2. Alternatively, the rolling frame can be further adjusted on the above structure and be provided with other similar structures, which can connect the two lower arc-changing mechanisms and facilitate the driving force of the rolling drive mechanism to be simultaneously transmitted to the two lower arc-changing mechanisms to drive the two lower arc-changing mechanisms to roll synchronously.

[0063] The rolling guide mechanism 6 is arranged at the lower part of the main frame 1, and two rolling guide mechanisms 6 are arranged on the two sides in the glass conveying direction, and the upper surface of the rolling guide mechanism 6 is a rolling surface. When the rolling surface is a horizontal surface, the length direction of the rolling guide mechanism 6 is parallel to the glass conveying direction, and the length direction of the rolling surface is parallel to the glass conveying direction. Preferably, the rolling guide mechanism 6 is a horizontal guide support structure, and the horizontal guide support structure is a limiting sliding groove with the notch facing upward.

[0064] The rolling drive mechanism 5 is a traction drive assembly arranged on the main frame 1, which includes a traction chain 501 and a traction motor. One end of the traction chain 501 is connected with the turnover shaft 202 on the rolling frame 2, and the other end is connected with the traction sprocket 502 on the traction motor. The traction motor drives the rolling frame 2 to roll by the traction chain 501. The traction drive assembly includes a left traction assembly and a right traction assembly. The left traction assembly is located at the inlet side of the forming equipment, and the traction chain 501 thereof is connected with the left side of the connecting lug at the end of the turnover shaft 202, for pulling the rolling frame 2 to the left, and driving the turnover forming mechanism 3 to roll to the inlet side. The right traction assembly is located at the outlet side of the forming equipment, and the traction chain 501 thereof is connected with the right side of the connecting lug at the end of the turnover shaft 202, for pulling the rolling frame 2 to the right, and driving the turnover forming mechanism 3 to roll to the outlet side. The left traction assembly and the right traction assembly can be connected to one drive motor, and the positive and negative rotation of the motor is used for control respectively, or one motor is arranged for control respectively.

[0065] Further, a reversing sprocket 503 is further arranged above the inlet side and the outlet side of the main frame 1 respectively, for tensioning and reversing the traction chain 501. The traction chain 501 in the left traction assembly and the right traction assembly is connected with the turnover shaft 202 after passing through the corresponding reversing sprocket 503.

[0066] Alternatively, in other embodiments, a traction steel wire can be used to replace the traction chain 501 in the rolling drive mechanism 5. The end of the traction steel wire is wound around the corresponding drum.

[0067] The variable-arc drive mechanism can adopt a chain pulling mechanism commonly used in the art, which includes a variable-arc motor and a pulling chain. The variable-arc motor is fixed on the rolling frame 2 or the main frame 1, and the pulling chain is connected with both ends of the lower variable-arc mechanism 302.

[0068] In other embodiments, the variable-arc drive mechanism can also use an electric cylinder 9. Both ends of the electric cylinder 9 are connected with both ends of the lower variable-arc mechanism 302 respectively. When the lower variable-arc mechanism 302 is in a flat state, the force moment of the electric cylinder 9 is 0, and the end of the lower variable-arc mechanism 302 cannot be pulled up. Therefore, an auxiliary pulling mechanism needs to be installed on the rolling frame 2 or the main frame 1. The auxiliary pulling mechanism pulls one end of the lower variable-arc mechanism 302 to a certain height by using a chain or a steel wire, and then drives the lower variable-arc mechanism 302 to bend into an arc by the electric cylinder 9. It should be noted that both ends of the electric cylinder 9 can be connected with both ends of the lower variable-arc mechanism 302 respectively, or can be connected through one hinged connecting piece respectively.

[0069] The plurality of lower roller beds 301 in the lower forming mechanism are driven by the roller drive chain 10 in the roller drive mechanism 8, to realize the rotation of the lower roller bed 301, and then to convey the glass.

[0070] In yet another embodiment, an upper roller track or upper roller is further provided above the lower roller track of the roll-over forming mechanism 3.

[0071] The forming apparatus of the above embodiments achieves the roll-over forming mechanism 3 to roll over in the same horizontal plane by the driving of the rolling frame 2 and the constraint of the traction constraint, better coordinates the feeding position, feeding angle of the glass when the glass is fed into the forming apparatus and the discharging position, discharging angle of the curved glass when the curved glass is discharged after forming, realizes the feeding of the hot glass in the same horizontal plane and the discharging of the curved glass in the same horizontal plane, eliminates the possibility of falling, reduces the glass bumping and deformation, does not need to set an additional inclined roller track connecting device, and can realize the forming and discharging of smaller radius glass. Moreover, the roll-over forming mechanism 3 is given a certain downward traction force when rolling over forward by the traction constraint of the traction constraint, so that the lower arc changing mechanism 302 closely advances along the rolling guide mechanism 6, realizes non-sliding roll-over, eliminates the unpredictability of the discharging position and discharging angle caused by sliding, and the roll-over process is more stable and effective.

[0072] In other embodiments, the lower arc changing mechanism 302 can also be replaced by other forms of forming units, for example, an arc plate can be used as a forming unit, the outer diameter surface of the arc plate is circular arc-shaped and matches the arc shape of the target glass, and the lower roller track is arranged on the two arc plates according to the arc shape of the target glass. After using the arc plate, the arc changing driving mechanism is not needed because the arc plate cannot change the arc.

[0073] The outer diameter surface of the arc plate matches the arc shape of the target glass, so that when the end of the outer diameter surface of the arc plate is horizontal during the roll-over of the arc plate, the forming surface inlet or outlet formed by the lower roller track is also horizontal, making the amplitude of the roll-over easier to control.

[0074] Because the arc plate cannot change the arc after using the arc plate, the shape of the forming surface of the lower roller track is fixed, so only one kind of curved glass with arc shape can be formed. If the arc needs to be changed, the arc plate with the corresponding arc surface needs to be replaced.

[0075] Embodiment 2

[0076] This embodiment is further optimized based on embodiment 1. In embodiment 1, after the lower arc changing mechanism 302 changes the arc, the spacing between the bottoms of the adjacent arc changing units increases, and the bottom of the arc changing unit will collide with the rolling guide mechanism 6 one by one during the roll-over of the roll-over forming mechanism 3. On the one hand, it will produce a lot of noise, and on the other hand, it will cause the wear of the bottom of the arc changing unit, affect the service life and rolling quality of the arc changing unit, and cannot accurately control the rolling stroke.

[0077] In order to solve the problem, the bottom of the down-arc mechanism 302 is further provided with an elastic slide plate 11 capable of being supported on the rolling guide mechanism 6, the elastic slide plate 11 extending along the length direction of the down-arc mechanism 302; the bottom of the down-arc mechanism 302 has a fixed part, the fixed part being fixedly connected with the elastic slide plate 11, and the rest part of the bottom of the down-arc mechanism 302 being provided with a limiting slide block 12, the edge of the elastic slide plate 11 in the length direction being slidably clamped on the limiting slide block 12.

[0078] It should be noted that the fixed part at the lower part of the down-arc mechanism 302 can be located at the film feeding end or the film discharging end of the down-arc mechanism 302, or can be located at the middle position of the two ends of the down-arc mechanism 302; the elastic slide plate 11 is provided with a fixed part corresponding to the fixed part, the fixed part of the elastic slide plate 11 being fixedly connected with the fixed part, and the corresponding fixed part can be located at the end of the elastic slide plate 11 or at the middle position of the elastic slide plate 11. At other positions of the elastic slide plate 11, the edge of the elastic slide plate 11 in the length direction is slidably clamped on the limiting slide block 12. That is, the elastic slide plate 11 only needs to have one position completely fixed on the down-arc mechanism 302, and the rest positions only need to be limited, the purpose being to meet the need of the elastic slide plate 11 bending into different radii along with the down-arc mechanism 302 on the basis of fixing the elastic slide plate 11, because the other positions of the elastic slide plate 11 will slide relative to the down-arc mechanism 302 at this time, so the elastic slide plate 11 cannot be completely fixed on the down-arc mechanism 302. Preferably, the limiting slide block 12 is an L-shaped slide block. Alternatively, a Z-shaped or T-shaped slide block can be used.

[0079] In the embodiment, one or two elastic sliding plates 11 are arranged at the bottom of each lower arc changing mechanism 302, and the length direction of the elastic sliding plate 11 is consistent with the length direction of the lower arc changing mechanism 302. Since the rolling guide mechanism 6 is a limiting sliding groove, when one elastic sliding plate 11 is arranged, the width of the elastic sliding plate 11 is sufficient to support the two sides of the elastic sliding plate 11 on the two sides of the sliding groove of the rolling guide mechanism 6; when two elastic sliding plates 11 are arranged, the two elastic sliding plates 11 are supported on the two sides of the sliding groove of the rolling guide mechanism 6. One end of the elastic sliding plate 11 is a fixed end, and the other end is a movable end. In the embodiment, the fixed part of the lower arc changing mechanism 302 is located at the film feeding end of the lower arc changing mechanism 302, the fixed end of the elastic sliding plate 11 is fixed at the bottom of the arc changing unit at the film feeding end of the lower arc changing mechanism 302, and the bottom of the remaining arc changing units of the lower arc changing mechanism 302 is clamped on the edge of the elastic sliding plate 11 through the limiting sliding block 12, so as to ensure that the elastic sliding plate 11 is bent during the arc forming of the lower arc changing mechanism 302. The length of the elastic sliding plate 11 is not less than the maximum outer circumferential arc length of the bottom of the lower arc changing mechanism 302 after the arc changing, so as to meet the support rolling of the lower arc changing mechanism 302 under different arc radii. The fixed part is located at the end of the lower arc changing mechanism 302, and the fixed end of the elastic sliding plate 11 is located at the end. The end is the film feeding end or the film discharging end. When the lower arc changing mechanism 302 is changed into different radii, the relative position between the fixed end of the elastic sliding plate 11 and the lower arc changing mechanism 302 is fixed, so that the film feeding position or the film discharging position can be kept consistent when the arc radius of the lower arc changing mechanism 302 is different. In addition, it should be noted that when two elastic sliding plates 11 are arranged at the lower part of each lower arc changing mechanism 302, the fixed ends of the two elastic sliding plates 11 are preferably arranged on the same side, and alternatively can be arranged on the opposite side, which can also meet the needs of film feeding, forming and film discharging.

[0080] After the elastic sliding plate 11 is adopted in the embodiment, the turnover forming mechanism 3 continuously contacts with the rolling guide mechanism 6 during the rolling process, so as to reduce the resistance in the rolling process, and the rolling process is more smooth and smooth, and the impact with the rolling guide mechanism 6 will not occur.

[0081] Further preferably, the first traction constraint 4 and the second traction constraint 7 are arranged at the bottom of the elastic sliding plate 11 and are located in the sliding groove of the rolling guide mechanism 6 in the flattened state, so as to ensure that the elastic sliding plate 11 can be in close contact with the rolling guide mechanism 6.

[0082] Specifically, when one elastic sliding plate 11 is arranged, the movable end of the first traction constraint 4 is connected with the movable end of the elastic sliding plate 11, and the movable end of the second traction constraint 7 is connected with the fixed end of the elastic sliding plate 11.

[0083] When two elastic slide plates 11 are arranged, the movable end of the first traction constraint 4 is connected with the movable end of one of the elastic slide plates 11, and the movable end of the second traction constraint 7 is connected with the fixed end of the other elastic slide plate 11.

[0084] Embodiment 3

[0085] This embodiment is further optimized on the basis of Embodiment 1 or 2, and mainly relates to the structural optimization of the turnover forming mechanism 3. The two ends of each of the plurality of lower roller tracks 301 are respectively connected with the corresponding lower arc changing mechanism 302 through an elastic plate 303.

[0086] Specifically, as shown in Figure 7 the end of each lower roller track 301 is arranged on the elastic plate 303 through a lower bearing seat 304, and the elastic plate 303 is arranged on the lower arc changing mechanism 301 through a plurality of lower connecting pieces. Preferably, the end of the lower roller track 301 is rotatably arranged on the lower bearing seat 304, and the bottom of the lower bearing seat is fixed on the elastic plate 301. Alternatively, the bottom of the lower bearing seat is clamped on the elastic plate, and the lower bearing seat and the elastic plate can slide relative to each other.

[0087] Preferably, at least one of the plurality of lower connecting pieces is fixedly connected with the elastic plate 303, and the remaining lower connecting pieces are slidably clamped on the edge of the elastic plate 303 in the length direction. The purpose of this arrangement is to meet the need that the elastic plate 303 is curved into different radii along with the lower arc changing mechanism 302, because at this time the other positions of the elastic plate 303 will slide relative to the lower arc changing mechanism 302. The lower connecting pieces and the lower bearing seat 304 are parts that play a corresponding connecting role, and the specific structure can be designed flexibly. The structure of the lower connecting piece that plays a fixedly connected role with the elastic plate 303 can be different from that of the lower connecting piece that plays a slidably clamped role with the elastic plate 303, so as to better play a corresponding role. Further preferably, one of the lower connecting pieces located at the entry end or the exit end of the lower arc changing mechanism 302 is fixedly connected with the elastic plate 303, which is more convenient for adjusting the entry position or the exit position. Preferably, the lower connecting piece that is fixedly connected with the elastic plate is a fixed plate, and the remaining lower connecting pieces can be L-shaped or T-shaped sliding blocks. It should be noted that the lower connecting piece can also be formed by splicing a plurality of sub-pieces.

[0088] In this embodiment, the elastic plate 303 is used to connect the lower roller track 301 and the lower arc changing mechanism 302, so that the installation of the lower roller track 301 is not directly dependent on the lower connecting plate of the corresponding lower arc changing mechanism 302. The center distance d between the two adjacent lower roller tracks 301 after installation can be less than the center distance D between the two adjacent lower pin shafts 302-1, so that the installation and arrangement of the thin roller track and the small-pitch roller track can be realized. In this way, the forming precision of the glass is improved, the straight edge of the glass is reduced, and the profile precision of the curved glass is improved.

[0092] Alternatively, as shown in Figure 8 The upper forming mechanism 3-2 can further comprise a plurality of upper roller tracks and two upper arc changing mechanisms, and the two upper arc changing mechanisms are respectively located above the two lower arc changing mechanisms, and the plurality of upper roller tracks are arranged on the two upper arc changing mechanisms. The structure of the upper arc changing mechanism is the same as that of the lower arc changing mechanism, and both are chain plate type arc changing mechanisms with lifting arcs. Further, an elastic plate is arranged between the upper arc changing mechanism and the upper roller track, and both ends of the upper roller track are respectively fixed on the elastic plate through upper bearing seats, and the elastic plate is connected with the upper arc changing mechanism on the same side through an upper connecting piece. The connection mode of the upper bearing seat and the upper connecting piece with the corresponding elastic plate is the same as the connection mode of the lower bearing seat and the lower connecting piece with the corresponding elastic plate in Embodiment 3.

[0093] This embodiment embodies two setting modes of the upper roller track, and both modes can realize synchronous arc changing of the upper roller track and the lower roller track, and the forming surfaces fitted by the plurality of upper roller tracks after arc changing are adapted to the forming surfaces fitted by the plurality of lower roller tracks after arc changing, so as to realize glass forming, rolling turnover and in-out sheet.

[0094] Embodiment 5

[0095] On the basis of the above embodiments, when the target radius of glass forming is different, the forming radius to be adjusted by the turnover forming mechanism is also different, and the outer peripheral arc length of the corresponding lower arc changing mechanism is different, that is, the rolling stroke from the horizontal in-sheet position to the horizontal out-sheet position in the rolling turnover process is also different, which will lead to different in-sheet positions or out-sheet positions.

[0096] To solve the problem, the adjustable roller mechanism is arranged on the basis of any of the above embodiments, the adjustable roller mechanism includes a plurality of tab roller tables, the plurality of tab roller tables can be independent and can be respectively disassembled and installed, or the plurality of tab roller tables are connected by a telescopic mechanism to adjust the horizontal distance and position between the plurality of tab roller tables, and the telescopic mechanism can adopt a scissor-type telescopic mechanism. The adjustable roller mechanism can be arranged at the inlet side or the outlet side inside the forming equipment, or independently arranged in front of or behind the forming equipment, or arranged at the inlet side of the tabbing equipment or the outlet position of the heating furnace of the downstream receiving section of the forming equipment.

[0097] Preferably, the adjustable roller mechanism is arranged at the outlet side of the forming equipment, and a telescopic adjustable roller mechanism is adopted. When the target radii of the front and rear glass forming are different, the tab inlet of the rolling and turning mechanism is turned over, the tab outlet position of the rolling and turning mechanism after turning over is different based on the same tab inlet position, and in order to compensate for the distance difference in the horizontal direction of the different tab outlet positions under different forming radii and smoothly receive the tabbed glass, the adjustable conveying roller is used to dock with the tab inlet of the rolling and turning mechanism at different positions.

[0098] Alternatively, in other embodiments, the adjustable roller mechanism can be arranged based on the same tab outlet position to realize docking with the tab inlet of the rolling and turning mechanism at different positions.
