Technical Field

[0001] This utility model belongs to the field of glass bending and forming, and specifically relates to a composite mold forming production line for forming curved glass. Background Technology

[0002] There are three common types of hyperboloid glass molding equipment: gravity forming, compression molding, and vacuum adsorption forming. These are suitable for bending curved glass of different thicknesses, radii, arch heights, and shapes with different precision requirements.

[0003] In the automotive industry, different mold forming equipment is required for the bending and tempering of high-, medium-, and low-quality double-curved or complex curved glass. Common mold forming equipment has low integration and can only achieve one forming method, unable to combine two or three forming methods. Manufacturers often need to set up two or three production lines to meet different production processes, resulting in high equipment costs. Utility Model Content

[0004] The purpose of this invention is to provide a composite mold forming production line for curved glass forming, which solves the problem of low integration of the original production line and realizes the flexible combination of various molds.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a composite mold forming production line for curved glass forming, including forming equipment and a reciprocating trolley, wherein the reciprocating trolley includes a horizontal moving mechanism; The molding equipment includes a molding frame, a conveying mechanism, a mold system, an upper lifting mechanism, and a lower lifting mechanism; the upper lifting mechanism is located at the upper part of the molding frame, and the lower lifting mechanism is located at the lower part of the molding frame; the mold system includes a pressing upper mold, an adsorption upper mold, a vehicle-mounted pressing lower mold, a lower heating mold, and a vehicle-mounted self-weight lower mold; The upper adsorption mold is detachably mounted on the upper lifting mechanism, and the lower hot mold is detachably mounted on the lower lifting mechanism for vacuum adsorption forming of curved glass. In the vacuum adsorption forming process, the transport ring for conveying the formed curved glass is detachably mounted on the horizontal moving mechanism. The upper pressing mold is detachably mounted on the upper lifting mechanism, and the vehicle-mounted lower pressing mold is detachably mounted on the horizontal moving mechanism of the reciprocating trolley, for molding and extruding curved glass. The vehicle-mounted self-weight lower mold is detachably mounted on the horizontal moving mechanism of the reciprocating trolley and is used for the self-weight forming and sheet output of curved glass.

[0006] The middle part of the vehicle-mounted pressing lower mold, the lower hot mold, the vehicle-mounted self-weight lower mold, and the transport ring is a hollow structure that allows the conveying mechanism to rise and fall relative to each other; Its beneficial effects are as follows: This composite mold forming production line, through the systematic integration design of multiple molds, enables flexible combination and selection of multiple molds. It can flexibly select different molds to be used according to the different requirements of different batches of glass to be bent, such as thickness, arch height of the target shape, shape complexity, and shape accuracy. It can also achieve continuous loading, forming, and unloading of sheets. The equipment has a high degree of integration and is flexible in use. One machine can continuously bend and form curved glass with different thicknesses, radii, arch heights, and shape accuracy requirements, thus expanding the forming capacity of the equipment.

[0007] Furthermore, the horizontal moving mechanism includes two guide rails, a portion of which extends into the molding frame and is fixed to the molding frame.

[0008] Its beneficial effects are: the guide rail extends into the molding frame, which can reliably and effectively support the vehicle-mounted self-weight mold and the vehicle-mounted pressing mold, and prevent the mold from being suspended in the air.

[0009] Furthermore, depending on the glass forming method, the conveying mechanism is connected to the forming frame or the lower lifting mechanism via a fixing member; the lower lifting mechanism includes a fixed frame, a lifting frame, and a conveyor frame, the lifting frame being driven by a lifting drive mechanism to vertically lift along the fixed frame; the conveyor frame is used to connect to and support the conveying mechanism, and the conveyor frame is connected to the forming frame or the lifting frame via a fixing member; the lifting frame is used to connect to the lower hot mold.

[0010] Its beneficial effects are as follows: When vacuum adsorption molding is performed, the lifting frame is connected to the lower hot mold and used to drive the lower hot mold to rise and fall, while the conveying mechanism is fixedly mounted on the molding frame. When self-weight or compression molding is performed, the lower hot mold is disassembled, at which point the lower lifting frame is connected to the conveyor frame and used to drive the conveying mechanism to rise and fall.

[0011] Furthermore, the dimensions of the conveyor frame are larger than the dimensions of the lifting frame.

[0012] Its beneficial effect is that when the conveyor frame is fixed on the forming frame, it will not affect the lifting of the lifting frame.

[0013] Furthermore, the conveyor frame is slidably connected to the forming frame via a sliding assembly.

[0014] Its beneficial effects are: it can reduce the frictional resistance of the conveyor frame as it moves up and down along the forming frame, and at the same time, it can provide guidance for its movement.

[0015] Furthermore, the conveying mechanism includes multiple flexible shaft roller conveyors.

[0016] Its beneficial effect is that it provides a commonly used form of conveying mechanism in this field, which is easy to implement.

[0017] Furthermore, the conveying mechanism includes multiple centralized transmission units arranged perpendicular to the glass conveying direction, wherein at least three of the centralized transmission units are respectively provided with multiple independent transmission units in their respective length directions. The independent transmission units are connected to conveying elements, and the multiple conveying elements arranged perpendicular to the glass conveying direction form a conveying group. The multiple conveying groups arranged in the glass conveying direction together form a conveying surface. A lifting mechanism is also connected below each centralized transmission unit to control the independent lifting of each centralized transmission unit. The multiple centralized transmission units are connected to a main transmission mechanism to realize centralized power input.

[0018] Its beneficial effects are as follows: This conveying system, through a three-stage transmission setup of centralized transmission units, independent transmission units, and conveying elements, enables the modular assembly of conveying elements. By controlling the raising and lowering of multiple centralized transmission units to specific heights, the position of each conveying element and the posture of each conveying group can be further controlled, thereby forming a conveying surface of a specific shape from multiple conveying groups. When the shape of the glass to be bent or the shape of the forming mold changes, by selecting a centralized transmission unit connected to an independent transmission unit, adjusting the position of the independent transmission unit in the glass conveying direction, the specifications of the conveying elements, the number of conveying elements, and controlling the raising and lowering of the centralized transmission unit, conveying surfaces of different shapes can be formed. This facilitates replacement and adjustment and allows for better matching with the forming mold.

[0019] Furthermore, at least one conveying element in at least one conveying group is a tiltable drive roller, which includes a roller body, a universal drive assembly, and an intermediate shaft; the intermediate shaft is connected to the roller body through a bearing, and one end of the intermediate shaft is disposed in the roller body, while the other end is machined into a ball head and extends out of the outside of the roller body; the inner end of the universal drive assembly is embedded in the roller body.

[0020] Its beneficial effects are: the roller can drive the roller body to rotate through the universal transmission component, while the intermediate shaft does not rotate, thus satisfying the installation and rotation of the roller under different degrees of tilt. The intermediate shaft does not wear under long-term use in an tilted posture, and the structure is simple and durable.

[0021] Furthermore, this utility model also includes a tempered section, which includes an upper air grille and a lower air grille.

[0022] Its beneficial effects are: the tempering section can achieve rapid cooling of the glass after thermoforming, and the air blowing of the lower air grille can be used to separate the glass from the vehicle-mounted pressing mold, the vehicle-mounted self-weight lower mold, or the transport ring, thus completing the unloading.

[0023] Furthermore, it also includes splicing units.

[0024] Its beneficial effect is that the splicing unit can realize the splicing of glass after the glass is separated from the vehicle-mounted pressing mold, the vehicle-mounted self-weight mold, or the transport ring.

[0025] The beneficial effects of this utility model are as follows: By systematically integrating and designing multiple molds, this utility model enables flexible combination and selection of various molds. It allows for the selection of different molds to be used in combination based on the varying requirements of different batches of glass to be bent, such as thickness, arch height, shape complexity, and shape precision. The equipment is highly integrated and flexible in use; a single machine can continuously bend curved glass of different thicknesses, radii, arch heights, and shape precision requirements, thus expanding the equipment's forming capacity.

Detailed Implementation

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention in any way.

[0028] Example 1 See attached document Figure 1-4 As shown, a composite mold forming production line for curved glass includes a forming device 100 and a reciprocating trolley 200. The forming device 100 includes a forming frame 1, a conveying mechanism 2, a mold system, an upper lifting mechanism 3, and a lower lifting mechanism 4. The upper lifting mechanism 3 and the lower lifting mechanism 4 are respectively located at the upper and lower parts of the forming frame 1. The mold system includes a pressing upper mold 11, an adsorption upper mold 12, a vehicle-mounted pressing lower mold 13, a lower heating mold 14, and a vehicle-mounted self-weight lower mold 15. The required mold is selected and installed according to the glass forming method. The reciprocating trolley 200 includes a horizontal moving mechanism 6, which includes guide rails 61 and a screw drive assembly. Two guide rails 61 are provided, and a portion of the guide rails 61 extends into the forming frame 1 and is fixed to the forming frame 1. The screw drive assembly is located on the reciprocating trolley 200. The mold required for glass forming or the transport ring 5 used for conveying glass is detachably connected to the slider on the guide rail on one hand and to the moving part of the lead screw drive assembly on the other hand, thereby realizing the linear movement of the mold or the transport ring.

[0029] In other embodiments, the lead screw drive assembly of the horizontal moving mechanism 6 may also employ mechanisms commonly used in the art, such as the cooperation of pulleys and grooves, the drive of a linear motor, etc.

[0030] The conveying mechanism 2 is connected to the forming frame 1 or the lower lifting mechanism 4 via a fixing component, depending on the glass forming method. For example... Figure 4As shown, the lower lifting mechanism 4 includes a fixed frame 41, a lifting frame 42, and a conveyor frame 43. The fixed frame 41 is fixedly installed at the bottom of the forming frame 1, and a lifting drive mechanism 44 is provided at the lower part of the fixed frame 41 for driving the lifting frame 42 to move vertically up and down on the fixed frame 41. The conveyor frame 43 is used to connect to and support the conveying mechanism 2, and the conveyor frame 43 can be connected to the forming frame 1 or the lifting frame 42 through fasteners such as bolts or adapter plates. When the conveying mechanism 2 needs to be lifted, the conveyor frame 43 is fixedly connected to the lifting frame 42; when the conveying mechanism 2 does not need to be lifted, the conveyor frame 43 is fixedly connected to the forming frame 1. The size of the conveyor frame 43 is larger than the size of the lifting frame 42, so that when the conveyor frame 43 is fixed to the forming frame 1, it will not affect the lifting of the lifting frame 42. Alternatively, the lower lifting mechanism can be set to two, namely a lower mold lifting mechanism and a lower conveyor lifting mechanism, which can be controlled independently. When the conveyor needs to be lifted, the lower mold lifting mechanism is not connected to the mold. When the lower hot mold needs to be lifted, the conveyor remains stationary.

[0031] Furthermore, the conveyor frame 43 is slidably connected to the forming frame 1 via a sliding assembly. This sliding assembly can be a slider and a slide rail structure, reducing the frictional resistance of the conveyor frame 43 as it moves up and down along the forming frame 1, while also providing guidance for its movement. When the conveyor frame 43 needs to drive the conveying mechanism 2 to move up and down, the lock between the slider and the slide rail can be released, and the conveyor frame 43 can be fixedly connected to the lifting frame 42. When the conveyor frame 43 does not need to drive the conveying mechanism 2 to move up and down, the connection between the conveyor frame 43 and the lifting frame 42 can be released, and the slider can be fixed to the slide rail using bolts or similar means. In other embodiments, a guide sleeve and guide rod structure can also be used as the sliding assembly.

[0032] The vehicle-mounted pressing lower mold 13, lower hot mold 14, vehicle-mounted self-weight lower mold 15, and transport ring 5 are all hollow structures. This structure allows for better integration with the conveying mechanism 2, which can move up and down within the hollow structure, enabling relative lifting and lowering of the curved glass on the vehicle-mounted pressing lower mold 13, lower hot mold 14, vehicle-mounted self-weight lower mold 15, and transport ring 5.

[0033] The following is in conjunction with the appendix Figure 1-3 The three molding methods are explained.

[0034] (1) The first forming method is vacuum adsorption forming, which is mainly suitable for thin glass, glass with high target arc arch height, complex shape, or high shape precision requirements. The forming mold involved in this forming method includes an upper adsorption mold 12 and a lower heating mold 14. For example Figure 1As shown, the upper adsorption mold 12 is detachably mounted on the upper lifting mechanism 3, and the upper lifting mechanism 3 drives the upper adsorption mold 12 to rise and fall. The lower hot mold 14 is detachably mounted on the lifting frame 42 of the lower lifting mechanism 4. The "detachable mounting" can be a bolt-fixed method. In the vacuum adsorption molding method, the conveyor frame 2 does not need to rise and fall with the lifting frame 42; therefore, the conveyor frame 43 of the lower lifting mechanism 4 is fixed on the molding frame 1.

[0035] Hot glass from the previous station or hot glass pre-bent in a pre-bending furnace is transported to the conveying mechanism 2 and placed into position. Then, the lower hot mold 14 is lifted by the lower lifting mechanism 4, which lifts the hot glass on the conveying mechanism 2 until it is adsorbed by the upper adsorption mold 12. The lower hot mold 14 then descends below the conveying mechanism 2. Next, the horizontal moving mechanism 6 on the reciprocating trolley 200 sends the transport ring 5 to the top of the conveying mechanism 2. The upper lifting mechanism 3 drives the adsorption mold 12 to fall, placing the formed glass on the transport ring 5. Finally, the horizontal moving mechanism 6 transfers the transport ring 5 along with the formed glass to the next station.

[0036] During this process, while the lower lifting mechanism 4 lifts the lower hot mold 14, the upper lifting mechanism 3 can also lower the upper adsorption mold 12 a certain distance to reduce the height at which the lower hot mold 14 is lifted and improve production efficiency.

[0037] (2) The second forming method is compression molding, which is mainly applicable to glass forming with a high arch height or complex shape. The forming mold required for this method is an upper pressing mold 11 and a vehicle-mounted lower pressing mold 13. The upper pressing mold 11 is detachably installed on the upper lifting mechanism 3, and the vehicle-mounted lower pressing mold 13 is detachably installed on the horizontal moving mechanism 6 of the reciprocating trolley 200. The conveyor frame 43 of the lower lifting mechanism 4 is fixedly connected to the lifting frame 42 and is used to drive the supported conveyor mechanism 2 to move vertically.

[0038] During the forming process, firstly, the horizontal moving mechanism 6 moves the vehicle-mounted pressing lower mold 13 to the forming frame 1 to the position to be formed. Then, the lower lifting mechanism 4 rises, driving the conveying mechanism 2 to rise, which is used to receive the hot glass transferred from the previous station or the hot glass pre-bent by the pre-bending furnace. Subsequently, the lower lifting mechanism 4 drives the conveying mechanism 2 to descend, and the conveying mechanism 2 places the received hot glass on the vehicle-mounted pressing lower mold 13. Then, the upper lifting mechanism 3 drives the pressing upper mold 11 to press down, cooperating with the vehicle-mounted pressing lower mold 13 to press the glass into shape. After forming, the horizontal moving mechanism 6 moves the vehicle-mounted pressing lower mold 13 out of the forming frame and transfers the formed glass to the next station, thereby realizing the forming and transfer of the glass sheet.

[0039] (3) The third forming method is gravity forming, which is mainly suitable for forming thick glass or glass with a low arch height. The forming mold involved in this forming method is a vehicle-mounted gravity lower mold 15, which is detachably installed on the horizontal moving mechanism 6 of the reciprocating trolley. The conveyor frame 43 of the lower lifting mechanism 4 is fixedly connected to the lifting frame 42 and is used to drive the supported conveyor mechanism 2 to rise and fall vertically. In this method, the upper lifting mechanism 3 does not participate in the glass forming, or the upper lifting mechanism 3 is not provided.

[0040] During the forming process, firstly, the horizontal moving mechanism 6 moves the vehicle-mounted self-weight lower mold 15 to the position to be formed. Then, the lower lifting mechanism 4 rises, driving the conveying mechanism 2 to rise, which is used to receive the hot glass that has been pre-bent in the pre-bending furnace. Subsequently, the lower lifting mechanism 4 drives the conveying mechanism 2 to descend, and the conveying mechanism 2 places the received hot glass on the vehicle-mounted self-weight lower mold 15, and the glass is formed by its own weight. Finally, the horizontal moving mechanism 6 moves the vehicle-mounted self-weight lower mold 15 out of the forming frame and transfers the formed glass to the next station, thereby realizing the forming and transfer of the glass sheet.

[0041] This composite mold forming production line integrates multiple molds into a systematic design, enabling flexible combination and selection of various molds. It can flexibly select different molds to be used according to different requirements such as the thickness, arch height, shape complexity, and shape accuracy of different batches of glass, and achieve continuous loading, forming, and unloading. The equipment has a high degree of integration and is flexible in use. A single machine can continuously bend and form curved glass with different thicknesses, radii, arch heights, and shape accuracy requirements, expanding the equipment's forming capacity and greatly saving the investment cost of the production line.

[0042] It should be noted that this composite mold forming production line cannot simultaneously achieve three forming methods to form glass. When bending and forming glass, only one mold corresponding to one forming method can be selected for use.

[0043] Example 2 In addition to the conventional flexible shaft conveying mechanism in the art, the conveying mechanism in Embodiment 1 can also employ, for example... Figure 5 The structure shown. Figure 5The conveying mechanism includes multiple centralized transmission units 23 arranged perpendicular to the glass conveying direction. At least three of these centralized transmission units 23 each have multiple independent transmission units 22 along their respective length directions. Each independent transmission unit 22 is connected to a conveying element 21. The multiple conveying elements 21 arranged perpendicular to the glass conveying direction form a conveying group, and the multiple conveying groups arranged in the glass conveying direction together form a conveying surface. A lifting mechanism 25 is also connected below each centralized transmission unit 23 to control the independent lifting of each centralized transmission unit 23, allowing the multiple conveying elements 21 of the conveying group to conform to a specific shape adapted to the glass shape. The multiple centralized transmission units 23 are collectively connected to a main transmission mechanism 24 for power input.

[0044] Specifically, the centralized transmission unit is as follows: Figure 6 As shown, the system includes a support pipe 230, on which a power output assembly 233 is arranged, and at its lower part is a transmission tensioning mechanism 231. The transmission tensioning mechanism 231 and the power output assembly 233 each include their own transmission pulleys and transmission belts. The transmission belts of both the transmission tensioning mechanism 231 and the power output assembly 233 are connected to a common transmission assembly 232 at the lower part of the support pipe 230. The transmission belt of the transmission tensioning mechanism 231 is also connected to the main transmission mechanism 24. By controlling the tension of its transmission belt, the main transmission mechanism 24 transmits power to multiple centralized transmission units 23 with different lifting degrees. Through the connection design of the two annular transmission belts of the transmission tensioning mechanism 231 and the power output component 233, the engagement between the transmission tensioning mechanism 231 of the centralized transmission unit 23 and the main transmission mechanism 24 is more stable at different lifting heights, resulting in more stable power transmission. This ensures the tension of the transmission belts when the main transmission mechanism 24 transmits power to multiple centralized transmission units 24 at different lifting levels, guaranteeing smooth power transmission from the active transmission wheel and making power transmission more stable. In this embodiment, the transmission belt of the centralized transmission unit 23 is selected as a chain or synchronous belt, and the transmission wheel is selected as a sprocket or pulley. The shared transmission component 232 includes a double-row sprocket or double-row pulley. When a double-row sprocket is used, the double-row sprocket is connected to the chain of the power output component 233 and the chain of the transmission tensioning mechanism 231, respectively.

[0045] The transmission tensioning mechanism 231 is located below the support tube 230 and includes a linear telescopic mechanism 2311, a slider 2312, a belt drive component 2313, a reversing wheel 2314, a slide rail 2315, and a tensioning wheel 2316. One end of the belt drive component 2313 is connected to the common transmission assembly 232, and the other end is connected to the tensioning wheel 2316. The tensioning wheel 2316 is rotatably mounted on the slider 2312, and the slider 2312 is slidably mounted on the slide rail 2315. The slide rail 2315 and the linear telescopic mechanism 2311 are both fixed to the lower surface of the support tube 230. The telescopic end of the linear telescopic mechanism 2311 is hinged to the slider 2312 to drive the slider 2312 to move along the slide rail 2315, thereby controlling the tension of the belt drive component 2313 and facilitating power transmission. The reversing wheel 2314 meshes with the lower layer of the belt drive component 2313, so that the belt drive component 2313 can mesh with the drive wheel on the main drive shaft in the main drive mechanism 24. Figure 6 (at point A in the diagram), thereby enabling the power of the main transmission mechanism 24 to be transmitted via the belt-type transmission component 2313 to the common transmission assembly 232, and then to the power output assembly 233. The transmission belts of the belt-type transmission component 2313 and the power output assembly 233 are preferably chains, but can also be synchronous belts. When using synchronous belts, the synchronous belt of the power output assembly 233 is a double-sided toothed synchronous belt. Multiple independent transmission units 22 mounted on the centralized transmission unit 23 draw power from the power output assembly 233 to drive the connected conveying element 21.

[0046] like Figure 7As shown, the independent transmission unit 22 includes a mounting plate 220, a lower shaft 221, a lower transmission wheel 222, a meshing transmission wheel 223, an upper shaft 225, and an upper transmission wheel 224. The lower shaft 221 is rotatably mounted on the lower part of the mounting plate 220. The meshing transmission wheel 223 and the lower transmission wheel 222 are fixedly mounted on the lower shaft 221. The meshing transmission wheel 223 and the lower transmission wheel 222 can be located on the same side of the mounting plate 220 or on opposite sides of the mounting plate 220. The upper shaft 225 is rotatably mounted on the upper part of the mounting plate 220. The upper transmission wheel 224 is fixedly mounted on one end of the upper shaft 225, and the other end of the upper shaft 225 is connected to the conveying element 21. The upper transmission wheel 224 and the lower transmission wheel 222 are connected by a transmission belt. The lower end of the mounting plate 220 is fixed to the support tube 230 of the corresponding centralized transmission unit 23 with screws. After the mounting plate 220 is fixed to the centralized transmission unit 23, the lower part of the meshing transmission wheel 223 meshes with the power output component (such as a chain) of the power output assembly 233 of the centralized transmission unit 23, realizing power access. Therefore, the required number of independent transmission units 22 can be selected and installed on the centralized transmission unit 23 as needed. After the independent transmission units 22 are installed, power can be transmitted from the centralized transmission unit 23 to the independent transmission units 22. The structure is simple and the power access is stable. The transmission belt in the independent transmission unit 22 is a chain or a synchronous belt, and the upper transmission wheel 224 and the lower transmission wheel 222 are selected as sprockets or pulleys.

[0047] The conveying element 21 is a roller or a wheel. When the conveying element 21 is a roller, each end of the roller is provided with a fixed support and an independent transmission unit 22. Multiple conveying groups can choose the same composition structure or different composition structures. Each conveying group can have an independent selection. The conveying group can optionally include 3 rollers, of which two rollers are symmetrically inclined and the middle roller is horizontally positioned; alternatively, the conveying group includes multiple wheels that fit into a specific shape, or the conveying group includes several rollers and multiple wheels, with the rollers horizontally positioned and located in the middle, and multiple wheels provided on both sides of the rollers. Multiple conveying elements 21 together form a specific posture, and multiple conveying groups form a conveying surface of a specific shape, such as a conveying surface that together forms a "︺" shape.

[0048] In this embodiment, the conveying system utilizes a three-stage transmission configuration consisting of a centralized transmission unit 23, independent transmission units 22, and conveying elements 21. This allows for the modular assembly of the conveying elements 21. By controlling the multiple centralized transmission units 23 to rise and fall to specific heights, the position of each conveying element 21 and the posture of each conveying group are further controlled, thereby forming a conveying surface of a specific shape from the multiple conveying groups. When the shape of the glass to be bent changes or the shape of the forming mold changes, different conveying surfaces can be formed by selecting a centralized transmission unit 23 connected to an independent transmission unit 22, adjusting the position of the independent transmission unit 22 in the glass conveying direction, adjusting the specifications and number of conveying elements 21, and controlling the rise and fall of the centralized transmission unit 23. This facilitates replacement and adjustment, and allows for better matching with different forming molds.

[0049] Example 3 Based on Example 2, such as Figure 8 As shown, the roller is a tiltable transmission roller, which includes a roller body 211, a universal transmission assembly 212, and an intermediate shaft 213. The intermediate shaft 213 is connected to the roller body 211 through a bearing 214, and one end of the intermediate shaft 213 is disposed in the roller body 211, while the other end is machined into a ball head and extends out of the roller body 211. The inner end of the universal transmission assembly 212 is embedded in the roller body 211, and the rotation of the universal transmission assembly 212 drives the roller body 211 to rotate, while the intermediate shaft 213 does not rotate.

[0050] This tiltable transmission roller can drive the roller body 211 to rotate via the universal transmission assembly 212, while the intermediate shaft 213 does not rotate, thus satisfying the installation and rotation of the roller under different tilting degrees. Under long-term use in a tilted posture, the ball end of the intermediate shaft 213 does not wear, and the structure is simple and durable.

[0051] Example 4 Based on the above embodiments, the composite mold forming production line also includes a tempering section and a sheet-joining unit. The tempering section includes an upper air grille and a lower air grille, and is located behind the forming equipment. The sheet-joining unit is also a hollow structure. The vehicle-mounted pressing lower mold 13, the vehicle-mounted self-weight lower mold 15, or the transport ring 5 are linked with the sheet-joining unit and mounted on the horizontal moving mechanism, and the two move synchronously.

[0052] The vehicle-mounted pressing mold 13, the vehicle-mounted self-weight lower mold 15, or the transport ring 5 bring the formed glass to the tempering section and swings and blows it. After the blowing is completed, the lower air grille continues to blow, so that the lower surface of the formed glass is exposed to the wind and blown upward to detach from the trolley. Then, the glass is moved to the bottom of the glass by the joining unit, the lower air grille stops blowing, the glass falls on the joining unit, and the joining unit moves the glass out of the tempering section.

[0053] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Those skilled in the art should understand that modifications or equivalent substitutions can be made to the specific implementation of this utility model with reference to the above embodiments. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model are within the protection scope of the pending claims.
