Description

TECHNICAL FIELD

[0002] The continuous hard shaft bending equipment is a bending glass tempering equipment that is more applied in the current market, and has the advantages of high production efficiency and good glass quality. However, the ordinary continuous hard shaft bending has great limitations, such as that the glass with a small radius cannot be normally sheeted, and the forming section of the ordinary continuous hard shaft bending is high and heavy, the turning angle is not suitable to be too large, and the turning process is also relatively dangerous. For example, the glass forming equipment in CN102826742A contains a turning forming mechanism, the equipment is provided with a rotating shaft at the input side, the forming mechanism can be turned by a certain angle around the rotating shaft, and then the sheet is outputted. In addition, CN207918695U adopts an inclined roller bed sheet connecting device to realize the connection between the sheet output port of the forming mechanism and the sheet table, so as to realize the sheet output of the formed curved glass, Figure 1 The sheet output principle of the forming mechanism cooperating with the inclined roller bed sheet connecting device is given, and it can be seen from the figure that when the forming mechanism 100 is turned to the sheet output position, the tangent line 400 of the formed curved surface in the forming mechanism 100 at the sheet output port and the roller bed surface of the inclined roller bed sheet connecting device 200 still have a large included angle β, β≥50°, at this time, the formed curved glass 500 cannot be stably outputted on the sheet connecting device 200, and there is still a large impact and collision. However, the equipment described in the above two prior arts cannot meet the higher market demand, and therefore a new glass bending forming equipment is proposed. CONTENT OF THE UTILITY MODEL

The connection relationship between the elastic slide plate and the lower arc changing mechanism can realize the function of bending the elastic slide plate into different radii along with the lower arc changing mechanism on the basis of fixing the elastic slide plate.

When the lower arc changing mechanism changes the arc to different radii, the relative position of the fixed end of the elastic slide plate and the lower arc changing mechanism remains fixed, so that the film feeding position or the film discharging position can remain consistent when the arc radius of the lower arc changing mechanism changes.

[0014] Further, the two ends of the plurality of lower roller ways are connected with the lower arc changing mechanisms on the corresponding sides through the elastic plates.

[0018] In addition, the outer diameter surface of the lower arc plate is an arc surface, and is matched with the arc of the target glass. Thus, when the end of the outer diameter surface of the arc plate is horizontal during the rolling and overturning process, the forming surface inlet or outlet formed by the lower roller is also horizontal, so that the rolling and overturning range is easier to control.

[0019] Further, the lower arc plate is provided with a first traction constraint and a second traction constraint.

DETAILED DESCRIPTION

[0058] The utility model will be further explained in detail in combination with the drawings and examples, but it is not as the basis for any limit of the utility model.

[0059] Example 1

[0060] As Figure 2 shown, a kind of glass forming equipment, including main frame 4, rolling frame 5, turnover forming mechanism 1, rolling drive assembly 7 and rolling guide mechanism 8.

[0061] The flipping forming mechanism 1 includes a lower forming mechanism for glass bending forming, and the bottom of the flipping forming mechanism 1 is supported on the rolling surface of the rolling guide mechanism 8. In this embodiment, the lower forming mechanism includes two lower arc-changing mechanisms 104 and multiple lower roller conveyors 103. The lower arc-changing mechanisms 104 are chain plate type arc-changing mechanisms commonly used in the art that can be lifted into an arc. Two lower arc-changing mechanisms 104 are provided, distributed on both sides of the glass conveying direction, and respectively supported on the two rolling guide mechanisms 8. The two ends of the multiple lower roller conveyors 103 are respectively connected to the two lower arc-changing mechanisms 104. After the lower arc-changing mechanisms 104 are bent into an arc, the multiple lower roller conveyors 103 fit together to form a forming curved surface for glass forming.

[0062] Furthermore, in the glass forming equipment described in this embodiment, the flipping forming mechanism 1 is directly placed and supported on the upper surface of the two rolling guide mechanisms 8, achieving stable support through its own weight. However, since the bottom of the lower arc-changing mechanism 104 is a steel plate or other metal plate structure, after contacting the rolling guide mechanism 8 made of the same metal material, the lower arc-changing mechanism 104 is prone to sliding on the rolling guide mechanism 8 during the rolling and flipping process. This makes it impossible to ensure that the inlet or outlet of the flipping forming mechanism 1 falls accurately in the same position before and after flipping, thus affecting the connection with upstream or downstream equipment. Therefore, to further increase the stability during the rolling and flipping process, traction constraint members are also provided on the glass forming equipment, including a first traction constraint member 6 and a second traction constraint member 9. A first traction constraint member 6 and a second traction constraint member 9 are provided below each lower arc-changing mechanism 104. The first traction constraint 6 and the second traction constraint 9 have the same structure, with a fixed end and a movable end at their two ends, respectively. The fixed end of the first traction constraint 6 is fixed to the main frame 4 or the rolling guide mechanism 8 on the inlet side of the molding equipment, and the movable end of the first traction constraint 6 is connected to the sheet-out end of the lower arc-changing mechanism 104. The fixed end of the second traction constraint 9 is fixed to the main frame 4 or the rolling guide mechanism 8 on the outlet side of the molding equipment, and the movable end of the second traction constraint 9 is connected to the sheet-in end of the lower arc-changing mechanism 104.

[0063] Specifically, when the flipping forming mechanism 1 moves from... Figure 3 The horizontal feed position shown is flipped to Figure 4 During the horizontal glass ejection process, the movable end of the first traction constraint 6 can tighten the exit end of the lower arc-changing mechanism 104. In conjunction with the fixed end of the first traction constraint 6, while the flipping forming mechanism 1 is rolling and flipping, the first traction constraint 6 provides a certain downward traction force, allowing the lower arc-changing mechanism 104 to advance closely along the rolling guide mechanism 8, achieving non-slip rolling and flipping. This eliminates the unpredictability of the ejection position and angle caused by slippage, making the rolling and flipping process more stable and effective. After the curved glass is ejected, the flipping forming mechanism 1...Figure 4 The horizontal sheet-out position shown is Figure 3 When the horizontal sheet-in position shown is rolling, the main constraint is provided by the second traction constraint 9, whose principle is the same as that of the first traction constraint 6.

[0064] In this embodiment, the first traction constraint 6 and the second traction constraint 9 can be steel wire ropes or chains.

[0065] In this embodiment, the glass forming device drives the rolling frame 5 and the traction constraint, and then drives the overturning forming mechanism 1 to roll along the rolling surface 3, so that the hot glass can be adjusted in the sheet-out position and the sheet-out angle after rolling and overturning after entering the overturning forming mechanism 1 horizontally, the curved glass after horizontal sheet-in and forming can be sheeted out at a smaller angle, the falling height is reduced or eliminated, and the forming and sheeting out of smaller radius glass can be realized.

[0066] The rolling guide mechanism 8, the rolling frame 5, the rolling drive mechanism and the arc changing drive mechanism used in this embodiment are described below.

[0067] The rolling guide mechanism 8 is arranged at the lower part of the main frame 4, and two rolling guide mechanisms 8 are arranged on both sides of the glass conveying direction, and the upper surface of the rolling guide mechanism 8 is the rolling surface. When the rolling surface is a horizontal surface, the length direction of the rolling guide mechanism 8 is parallel to the glass conveying direction, and the length direction of the rolling surface is parallel to the glass conveying direction, and preferably, the rolling guide mechanism 8 is a horizontal guide support structure, and the horizontal guide support structure is a limiting sliding groove with the notch facing upward.

[0068] The rolling frame 5 is connected to the overturning forming mechanism 1, and the rolling frame 5 includes a support arm 501 and an overturning shaft 502, the lower end of the support arm 501 is fixedly connected to the outer side of the end part of the lower arc changing mechanism 104, and each end of the lower arc changing mechanism 104 is connected to one support arm 501, and the upper ends of the two support arms 501 on the same side are obliquely intersected so as to be connected to the end part of the overturning shaft 502. A support rod is further connected between the two support arms 501 with the same oblique direction connected to the two lower arc changing mechanisms 104 respectively, so as to enhance the strength of the rolling frame 5. Alternatively, the rolling frame 5 can be further adjusted on the above structure to be arranged as other similar structures, which can connect the two lower arc changing mechanisms 104, facilitate the driving force of the rolling drive mechanism to be transmitted to the two lower arc changing mechanisms 104 simultaneously, and drive the two lower arc changing mechanisms 104 to roll synchronously.

[0069] The rolling drive assembly 7 is a traction drive assembly arranged on the main frame 4, comprising a traction chain 701 and a traction motor.

[0070] The arc changing drive mechanism is connected with the end of the lower arc changing mechanism 104 to drive the lower arc changing mechanism 104 to bend into an arc. Figure 9 The electric cylinder 12 is used as the arc changing drive mechanism, and the two ends of the electric cylinder 12 are connected with the two ends of the lower arc changing mechanism 104 respectively.

[0071] The plurality of lower roller ways 103 in the lower forming mechanism are driven by the roller way drive chain 13 in the roller way drive mechanism 10 to realize the rotation of the lower roller way 103 and then to convey the glass.

[0072] It should be noted that the rolling type overturning of the overturning forming mechanism 1 in the utility model means that the overturning forming mechanism 1 rolls along the lower rolling surface under the drive of external force, so as to realize the overall overturning and the conversion between the sheet feeding state and the sheet discharging state.

[0073] In the embodiment, the rolling surface of the rolling guide mechanism 8 is a horizontal rolling surface, so that the central axis of the forming curved surface moves along the horizontal plane during the rolling type overturning of the overturning forming mechanism. Figure 5As shown, the center axis of the molding curved surface is in the center horizontal plane 11 during the process that the flip molding mechanism 1 flips from the left side sheet feeding position to the right side sheet discharging position.

[0074] In other embodiments of the present embodiment, the rolling surface of the rolling guide mechanism 8 can also be an inclined surface or a curved surface.

[0075] Further, in other embodiments, a baffle protruding from the rolling surface can be further arranged outside the rolling surface of the rolling guide mechanism 8, and a limiting plate protruding from the rolling surface can be further arranged at each of the front and rear ends of the rolling surface. The arrangement of the limiting plate can prevent the flip molding mechanism from straying out of the rolling surface when an error occurs, and the baffle can prevent the flip molding mechanism from moving left and right and leaving the rolling surface during the flipping process.

[0076] The technical principles and effects of the present application will be further illustrated below with reference to the accompanying drawings. Figures 6-8 The way of feeding and discharging glass by the glass molding equipment described in the present embodiment will be explained to better understand the technical principles and effects of the present application.

[0077] When the glass molding equipment is used to mold curved glass, the hot flat glass 600 enters the flip molding mechanism 1 through the feeding port 101 of the flip molding mechanism 1 along the horizontal conveying surface and is bent to form a curved surface, and then the flip molding mechanism 1 rolls along the rolling surface 3 to the discharging position of the glass molding equipment, and when the flip molding mechanism 1 reaches the discharging position, the tangent line 400 of the molding curved surface in the flip molding mechanism 1 at the discharging port forms an angle α with the sheet connecting horizontal plane 2, preferably, the sheet connecting horizontal plane 2, -15°≤α≤15°, and when discharging, the molded curved glass 500 leaves the flip molding mechanism 1 from the discharging port 102 of the flip molding mechanism 1 and enters the sheet connecting horizontal plane 2.

[0078] As shown in FIG. 4, when the tangent line 400 of the molding curved surface at the discharging port coincides with the sheet connecting horizontal plane 2, α=0°, and the curved glass 500 can be horizontally discharged. Figure 6 As shown in FIG. 5, when the tangent line 400 of the molding curved surface at the discharging port is above the sheet connecting horizontal plane 2, 0°<α≤15°, and the curved glass 500 has a larger upward amplitude when discharged compared with the horizontal discharging. Figure 7 As shown in FIG. 6, when the tangent line 400 of the molding curved surface at the discharging port is below the sheet connecting horizontal plane 2, -15°≤α<0°, and the curved glass 500 is discharged in a relatively diving posture. Compared with the horizontal discharging, the three discharging modes have different advantages. Figure 8 Figure 1 ​The existing sheet-out mode shown has a smaller sheet-out angle, which can greatly reduce the falling sheet height and even eliminate the falling sheet, has a small impact on the glass quality, and has a smaller risk of glass breakage. In addition, when forming a glass with a small radius, the forming equipment of the prior art CN102826742A and CN207918695U has a larger included angle β between the tangent line 400 of the forming curved surface at the sheet-out port and the roller surface of the inclined roller interface device (as shown in Figure 1 The present application can achieve smooth sheet-out of a small-radius glass.

[0079] It should be noted that the forming curved surface is a forming surface of the glass received by the plurality of lower rollers, and the target arc of the curved glass is the arc of the surface of the target curved glass in contact with the lower rollers. Alternatively, the interface plane can not be a completely horizontal interface plane, but can be an inclined plane with a certain inclination angle, and the interface can also be achieved.

[0080] Embodiment 2

[0081] This embodiment is further optimized on the basis of Embodiment 1, as shown in Figure 10 The bottom of each lower arc-changing mechanism 104 of the turnover forming mechanism 1 is provided with an elastic sliding plate 14, and the length direction of the elastic sliding plate 14 is consistent with the length direction of the lower arc-changing mechanism 104. The first traction constraint 6 and the second traction constraint 9 are arranged at the bottom of the elastic sliding plate 14. The bottom of the lower arc-changing mechanism 104 has a fixed portion, and the fixed portion is fixedly connected with the elastic sliding plate 14. The remaining portions of the bottom of the lower arc-changing mechanism 104 are provided with a plurality of limiting sliding blocks 15, and the edges of the elastic sliding plate 14 in the length direction are slidably clamped on the limiting sliding blocks 15.

[0082] It should be noted that the fixed part of the lower part of the lower arc changing mechanism 104 can be located at the film feeding end or the film discharging end of the lower arc changing mechanism 104, or can be located at the middle position of the two ends of the lower arc changing mechanism 104. The elastic slide plate 14 is provided with a fixed part corresponding to the fixed part, and the fixed part of the elastic slide plate 14 is fixedly connected with the fixed part. The corresponding fixed part can be located at the end of the elastic slide plate 14, or can be located at the middle position of the elastic slide plate 14. At other positions of the elastic slide plate 14, the length direction edge of the elastic slide plate 14 is slidably clamped on the limiting slide block 15. That is, the elastic slide plate 14 only needs to have one position completely fixed on the lower arc changing mechanism 104, and the remaining other positions only need to be limited. The purpose is to meet the needs of the elastic slide plate 14 bending with the lower arc changing mechanism 104 into different radii on the basis of fixing the elastic slide plate 14. Because the other positions of the elastic slide plate 14 will slide relative to the lower arc changing mechanism 104 at this time, the elastic slide plate 14 cannot be completely fixed on the lower arc changing mechanism 104. Preferably, the limiting slide block is an L-shaped slide block. Alternatively, a Z-shaped slide block can also be used.

[0083] Further, in other embodiments, the fixed part of the lower arc changing mechanism 104 is located at the film feeding end of the lower arc changing mechanism 104, and one end of the elastic slide plate 14 is a fixed end and the other end is a movable end. The fixed end of the elastic slide plate 14 is fixed on the fixed part at the bottom of the film feeding end of the lower arc changing mechanism 104, and the length direction edge of the elastic slide plate 14 is slidably clamped on the plurality of limiting slide blocks 15 to ensure that the lower arc changing mechanism 104 drives the elastic slide plate 14 to bend during the arc forming process. The length of the elastic slide plate 14 is not less than the maximum outer edge arc length of the bottom of the lower arc changing mechanism 104 after the arc changing, so as to meet the support rolling of the lower arc changing mechanism 104 under different arc radii. The fixed part is located at the end of the lower arc changing mechanism 104, and the fixed end of the elastic slide plate 14 is located at the end. The end is the film feeding end or the film discharging end. When the lower arc changing mechanism 104 is changed into different radii, the relative position between the fixed end of the elastic slide plate 14 and the lower arc changing mechanism 104 is fixed, so that the film feeding position or the film discharging position can remain unchanged when the arc radius of the lower arc changing mechanism 104 is different. In addition, it should be noted that when two elastic slide plates 14 are arranged at the lower part of each lower arc changing mechanism 104, the fixed ends of the two elastic slide plates 14 are preferably arranged on the same side, or alternatively can be arranged on the opposite side, which can also meet the needs of film feeding, forming and film discharging.

[0084] After the elastic slide plate 14 is used in the present embodiment, the turnover forming mechanism 1 continuously contacts the rolling guide mechanism 8 through the elastic slide plate 14 during the rolling process, so that the rolling process is smoother and more smooth, and the impact with the rolling guide mechanism 8 will not occur. The rolling resistance can also be reduced.

[0085] More preferably, the first traction constraint 6 and the second traction constraint 9 are disposed at the bottom of the elastic slide plate 14 and located in the groove of the rolling guide mechanism 8, so as to ensure that the elastic slide plate 14 can be in close contact with the rolling guide mechanism 8.

[0086] Specifically, when one elastic slide plate 14 is provided at the bottom of each lower arc mechanism 104, the movable end of the first traction constraint 4 is connected to the movable end of the elastic slide plate, and the movable end of the second traction constraint 7 is connected to the fixed end of the elastic slide plate.

[0087] When two elastic slide plates 14 are provided at the bottom of each lower arc mechanism 104, the movable end of the first traction constraint 4 is connected to the movable end of one of the elastic slide plates, and the movable end of the second traction constraint 7 is connected to the fixed end of the other elastic slide plate.

[0090] like Figure 11 As shown, the two ends of the lower roller conveyor 103 are respectively connected to the corresponding lower arc-changing mechanism 104 via an elastic plate 16. Specifically, the end of each lower roller conveyor 103 is mounted on the elastic plate 16 via a lower bearing seat 17, and the elastic plate 16 is mounted on the lower arc-changing mechanism 104 via multiple lower connecting members.

[0091] Preferably, the end of the lower roller conveyor 103 is rotatably mounted on the lower bearing seat 17, and the bottom of the lower bearing seat 17 is fixed on the elastic plate 16. Alternatively, the bottom of the lower bearing seat 17 is engaged with the elastic plate 16, and the lower bearing seat 17 and the elastic plate 16 can slide relative to each other.

[0092] Preferably, at least one of the plurality of lower connectors is fixedly connected to the elastic plate 16, and the remaining lower connectors are slidably arranged on the edges of the elastic plate 16 in the length direction. The purpose is to meet the need that the elastic plate 16 is curved into different radii along with the lower arc changing mechanism 104, on the basis of fixing the elastic plate 16, because the other positions of the elastic plate 16 will slide relative to the lower arc changing mechanism 104. The lower connectors and the lower bearing seat 17 are parts for corresponding connection, and the specific structure can be designed flexibly. The lower connector for fixedly connecting the elastic plate 16 can be different from the lower connector for slidably arranging on the elastic plate 16, so as to better play the corresponding role. Further preferably, one of the lower connectors at the entry end or the exit end of the lower arc changing mechanism 104 is fixedly connected to the elastic plate 16, which is more convenient for adjusting the entry position or the exit position. Preferably, the lower connector fixedly connected to the elastic plate is a fixed plate, and the remaining lower connectors can be L-shaped or T-shaped sliders. It should be noted that the lower connector can also be formed by splicing a plurality of sub-parts.

[0093] In the embodiment, the elastic plate 16 is used to connect the lower roller 103 and the lower arc changing mechanism 104, so that the lower roller 103 is not directly attached to the corresponding lower connecting plate of the lower arc changing mechanism 104, and the center distance d between the two adjacent lower rollers 103 after installation is less than the center distance D between the two adjacent pin shafts 104-1, so that the installation of the thin roller and the small-pitch roller can be realized, the pitch between the rollers is reduced, 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.

[0094] Embodiment 4

[0095] On the basis of any one of the above-mentioned embodiments 1-3, the flip forming mechanism further comprises an upper forming mechanism, as shown in Figure 12 The upper forming mechanism comprises a plurality of upper rollers 108.

[0096] Optionally, the upper roller 108 can be arranged on the fixed seat connected with the lower roller 103 by the air cylinder 107, so as to realize the installation of the upper roller 108, and the position of the upper roller 108 can be adjusted by the air cylinder, so as to realize the adjustment of the distance between the upper roller 108 and the lower roller 103.

[0097] Alternatively, the upper forming mechanism includes a plurality of upper roller tables 108 and two upper arc changing mechanisms, the two upper arc changing mechanisms are respectively located above the two lower arc changing mechanisms 104, and the plurality of upper roller tables 108 are arranged on the two upper arc changing mechanisms.

[0099] Embodiment 5

[0100] As shown in Figure 13 , 14 , the difference between the embodiment and Embodiment 1 is that the lower forming mechanism in the overturning forming mechanism 1 includes two lower arc plates 105 and a plurality of lower roller tables 103 arranged on the two lower arc plates 105, the plurality of lower roller tables 103 fit to form a forming curved surface which is matched with the curved surface of the target curved surface glass; the bottom of the lower arc plate 105 is an arc surface supported on the rolling guide mechanism 8.

The fixed end of the first traction constraint 6 is connected with the main rack 4 or the rolling guide mechanism 8 on the inlet side of the glass forming equipment, and the movable end of the first traction constraint 6 is connected with the out sheet end of the lower arc plate 105. The movable end of the second traction constraint 9 is connected with the in sheet end of the lower arc plate 105, and the fixed end of the second traction constraint 9 is connected with the main rack 4 or the rolling guide mechanism 8 on the outlet side of the glass forming equipment.

[0102] The lower forming mechanism in the embodiment adopts the lower arc plate 105, and also can realize the rolling overturning, so that the overturning of the lower arc plate 105 and the overturning of the forming curved surface are synchronous. When one end of the bottom arc surface of the lower arc plate 105 overturns to the out sheet position, the tangent line of the corresponding out sheet port of the forming curved surface is parallel to the horizontal plane, realizing the horizontal in sheet and horizontal out sheet, so that the overturning of the overturning forming mechanism is easier to control.

[0103] Further, with reference to Figure 14As shown, the turnover forming mechanism 1 further comprises an upper forming mechanism, which has the same structure as the lower forming mechanism and comprises two upper arc plates 109 and a plurality of upper roller tracks 108 arranged on the two upper arc plates 109. The plurality of upper roller tracks 108 fit into an upper forming surface which is adapted to the forming curved surface, and a channel for the glass to enter the bending forming is formed between the upper forming surface and the forming curved surface.

[0104] Further, a lifting mechanism is further connected to the upper arc plate 109 to control the lifting of the upper arc plate 109 and adjust the distance between the upper roller track 108 and the lower roller track 103. The lifting mechanism comprises a lifting motor 110, a chain and a guide assembly. The lifting motor 110 is fixed on the rolling frame 5, the chain is connected to the lifting motor 110 and the two ends of the upper arc plate 109, and the upper arc plate 109 is lifted vertically by the lifting motor 110 through the chain. The guide assembly comprises a guide rod 111 and a sliding block 112. The upper end of the guide rod 111 is fixed on the rolling frame 5, the lower end of the guide rod 111 is fixed on the outer side of the lower arc plate 105, and the sliding block 112 is slidingly installed on the guide rod 111 and fixed on the outer side of the upper arc plate 109. The vertical lifting of the upper arc plate 109 is ensured by the sliding of the sliding block 112 along the guide rod 111.

[0105] In this embodiment, the arc plate structure is adopted, and the arc shape of the forming curved surface is determined by the shape of the arc plate. Therefore, the variable-arc driving mechanism is not needed, and when the curved surface glass with different bending radii needs to be produced, the arc plate with the corresponding shape can be replaced.

[0106] Embodiment 6

[0107] As shown in Figure 15 , 16 The difference between this embodiment and embodiment 5 is that the lower arc-shaped tooth plate 106 is used instead of the lower arc plate 105 in the turnover forming mechanism which only comprises the lower forming mechanism, and the upper arc plate 109 is still used when the turnover forming mechanism further comprises the upper forming mechanism. The upper arc plate 109 and the lower arc-shaped tooth plate 106 cooperate. The lower arc-shaped tooth plate 106 is provided with a tooth-shaped curved surface, and a plurality of teeth are arranged on the tooth-shaped curved surface. The plurality of teeth fit into the curved surface supported on the rolling guide mechanism 8. The rack 113 is arranged on the rolling surface of the rolling guide mechanism 8. Through the meshing of the lower arc-shaped tooth plate 106 and the rack 113, the non-sliding rolling turnover of the turnover forming mechanism is realized. Therefore, the first traction constraint 6 and the second traction constraint 9 are not needed in this embodiment.

[0108] Embodiment 7

[0109] Due to different target radii of the glass forming, the forming radius of the roll-over forming mechanism needs to be adjusted, and the outer edge arc length of the corresponding down arc mechanism or the outer edge arc length of the down arc plate is different, that is, the rolling stroke from the horizontal feeding position to the horizontal output position during the roll-over is different, which will cause different feeding positions or output positions.

[0111] Preferably, the adjustable roller mechanism is arranged at the end of the main rack of the glass forming apparatus, and a telescopic adjustable roller mechanism is used. When the target radii of the two types of glass forming are different, the output position of the output port of the roll-over forming mechanism after the roll-over is different based on the same feeding position of the feeding port of the roll-over forming mechanism. In order to compensate for the distance difference in the horizontal direction of different output positions under different forming radii, and smoothly receive the output glass, the conveying surface length of the adjustable roller mechanism is adjusted to be connected with the output port of the roll-over forming mechanism at different positions.

[0112] Alternatively, the adjustable roller mechanism can be arranged at the above-mentioned different devices or positions, and can be connected with the feeding port of the roll-over forming mechanism at different positions based on the same output position.
