Description

Technical Field

[0001] This utility model belongs to the technical field of automotive glass processing equipment, specifically relating to a transmission and conveying device for automotive glass forming. Background Technology

[0002] Automotive glass hot bending typically uses hollow molds. When heated to a softened state, the glass is conveyed into the hollow mold, where its edges are supported around the mold. This, combined with the closing of the upper mold, ensures precise mold-forming. Generally, a liftable conveyor system is installed inside the hollow mold to coordinate with an external conveyor system, transporting the hot glass into the mold. Belt conveyor technology is commonly used to improve synchronization and prevent relative slippage between rollers and the glass; however, design flaws in existing belt drive systems still limit their efficiency.

[0003] First, traditional belt-driven conveyor systems use an integrated main drive shaft, requiring the complete disassembly of the transmission assembly for synchronous belt replacement. This leads to increased downtime and higher maintenance costs, making it difficult to meet the maintenance needs of automotive glass production lines. Second, the number and spacing of existing belt-driven pulley sets are fixed, preventing rapid adjustments to the transmission and conveyor unit layout based on different automotive glass sizes, thus hindering flexible upgrades for multi-specification glass production lines. These issues severely impact the yield rate and production line changeover efficiency of automotive glass forming processes, necessitating improvements to the transmission and conveyor system to enable rapid equipment maintenance and dynamic combination functions during production. Utility Model Content

[0004] The purpose of this invention is to provide a transmission and conveying device for automotive glass forming, which can meet the differentiated driving requirements of different glass sizes, reduce energy consumption, and reduce the time required for equipment maintenance.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a transmission and conveying device for automotive glass forming, comprising a conveying mechanism and a main transmission mechanism; the conveying mechanism includes a transmission profiles spaced apart along a direction perpendicular to the glass conveying direction, and a centralized transmission pulley and a centralized transmission synchronous belt are provided inside the transmission profiles; b first conveying components are selectively arranged above the transmission profiles along a direction perpendicular to the glass conveying direction; the centralized transmission synchronous belt provides power to the first conveying components, where a ≥ b; the main transmission mechanism includes a main transmission motor, a main transmission shaft, m transition shafts and a transition pulleys, the transition pulleys are arranged on the transition shafts, where 1 < m ≤ a; the main transmission motor drives the transition shafts and transition pulleys to rotate through the main transmission shaft, and the centralized transmission synchronous belt and b transition pulleys in the b transmission profiles with the first conveying components are connected one-to-one.

[0006] Its beneficial effects are: the number and location of the first conveying components can be selected according to the size of the glass being processed, avoiding idle power and thus reducing the energy consumption of the entire equipment.

[0007] Furthermore, the main transmission mechanism also includes multiple main transmission units, each equipped with a short transmission shaft, and the short transmission shafts of the multiple main transmission units are connected in series via couplings to form the main transmission shaft.

[0008] Its beneficial effects are: the main drive shaft adopts a disconnected structure, and multiple main drive units are connected in series through couplings. In this way, when forming glass of different sizes, the number of main drive units can be increased or decreased, improving the adaptability of the equipment. It can also avoid the power being idle in non-working areas, further reducing the energy consumption of the equipment.

[0009] Furthermore, the main transmission unit also includes a support, on which the short transmission shaft and the transition shaft are mounted, and within the support is a transmission wheel assembly connecting the short transmission shaft and the transition shaft.

[0010] Its beneficial effect is that by utilizing the integrated design of the internal space of the support, the volume of the main drive unit can be reduced.

[0011] Furthermore, the transmission wheel assembly includes a first transmission wheel, a second transmission wheel, and a transmission tension wheel. The first transmission wheel is fixedly connected to the short transmission shaft, the second transmission wheel is fixedly connected to the transition shaft, and the transmission tension wheel is used to adjust the tension of the transmission belt between the first transmission wheel and the second transmission wheel.

[0012] Its beneficial effects are: it clarifies the structure of the transmission pulley set and ensures that the transmission belt is always in the best working condition by the transmission tensioner.

[0013] Furthermore, the first conveying assembly includes a plurality of first conveying units arranged along the glass conveying direction. Each first conveying unit includes a support frame and first conveying members symmetrically installed on both sides of the support frame. The first conveying members are used to convey the glass into the hollow mold of the forming device.

[0014] Its beneficial effects are: for narrow glass, the first conveying components on both sides of the first conveying unit provide good transmission and support.

[0015] Furthermore, the conveying mechanism also includes a second conveying assembly located outside the hollow mold of the forming device, for receiving glass conveyed from the pre-bending furnace; the second conveying assembly includes at least one second conveying unit, the second conveying unit including a support frame and a second conveying component mounted on the support frame.

[0016] Its beneficial effects are: the multiple conveying components on the transmission profile are divided into a first conveying component and a second conveying component according to their positional relationship with the hollow mold on the forming device. The second conveying component is used to connect to the pre-bending furnace, and the first conveying component is used to cooperate with the hollow mold. The dense arrangement of the first conveying components can ensure the forming accuracy, and the second conveying component can avoid interference with the mold during lifting. The number and installation position of the first conveying unit and the second conveying unit can be selected according to the size of the glass being processed.

[0017] Furthermore, the second conveying assembly also includes at least one third conveying unit, which includes a pair of support frames and a third conveying member mounted therebetween, the length of which is greater than the sum of the lengths of the two second conveying members in the second conveying unit.

[0018] Its beneficial effects are: the third conveyor can have a larger contact area with the glass, ensuring the safety of the splicing, and is suitable for the smooth splicing of large-size glass.

[0019] Furthermore, the support frame is fixedly connected to the transmission profile, and a transmission assembly for driving the first or second conveyor to rotate is provided inside the support frame. The centralized transmission pulley and the centralized transmission synchronous belt can provide power to the transmission assembly.

[0020] Its beneficial effects are: effective use of the internal space of the support frame through integrated design.

[0021] Furthermore, the transmission profile is provided with a side-opening installation space, within which the centralized transmission pulley and centralized transmission synchronous belt are arranged. The centralized transmission pulley includes multiple support pulleys, which are used to support the upper layer of the centralized transmission synchronous belt and transmit power to the transmission components in the support frame one-to-one through the side opening of the installation space.

[0022] Its beneficial effects are: each conveying unit is independently controlled, avoiding slippage caused by uneven power transmission; the spacing of the support pulleys is adjustable to adapt to the density requirements of different conveying units; the side opening design facilitates the connection between the transmission components of the support frame and the centralized transmission pulleys in the transmission profile, and also facilitates the quick assembly and disassembly of the synchronous belt.

[0023] Furthermore, the second conveying group is also equipped with a photoelectric switch for detecting the position of the glass.

[0024] Its beneficial effects are: by detecting the glass position in real time through photoelectric switches, the equipment can be started and stopped precisely and speed can be easily adjusted.

[0025] Furthermore, the conveying mechanism also includes a transmission tensioning mechanism, which is disposed on the lower surface of the transmission profile and is used to tension the centralized transmission synchronous belt; the centralized transmission synchronous belt extends from the opening on the lower surface of the transmission profile and is connected to the transmission tensioning mechanism.

[0026] Its beneficial effects are: the transmission tensioning mechanism can ensure the tension of the centralized transmission synchronous belt to adapt to the changes in distance between the transmission profile and the main drive motor caused by the lifting of the transmission profile, and the transmission tensioning mechanism can loosen the centralized transmission synchronous belt to realize quick disassembly and assembly of the centralized transmission synchronous belt, which is convenient for maintenance and replacement.

[0027] Furthermore, the transmission tensioning mechanism includes a telescopic mechanism, a slider rail assembly, and a tensioning synchronous pulley. The slide rails in the telescopic mechanism and the slider rail assembly are disposed on the lower surface of the transmission profile. The telescopic end of the telescopic mechanism is hinged to the slider in the slider rail assembly. The tensioning synchronous pulley is rotatably disposed on the slider.

[0028] Its beneficial effects are: it provides a specific structure for the transmission tensioning mechanism, facilitating implementation; this structure can ensure a smooth tensioning process and reduce vibration through the slider and slide rail assembly. The tensioning mechanism can be used to replace the synchronous belt or to disconnect the power; for non-working areas, only the telescopic mechanism needs to be adjusted to disconnect the synchronous belt.

[0029] Furthermore, it also includes a lifting mechanism, which is connected to the transmission profile to control the lifting of the first conveying component and the second conveying component above the transmission profile. The lifting mechanism is mounted on the support beam.

[0030] By controlling the independent lifting of the first and second conveying components through the lifting mechanism, multiple conveying components can be raised and lowered to different heights, thereby adjusting the shape of the conveying surface formed by the conveying components to match the curved surface of the glass output from the pre-bending furnace, thus improving the safety and reliability of pre-bent glass conveying.

[0031] The beneficial effects of this utility model are as follows: 1. This utility model adopts a centralized multi-point transmission method, in which a main drive motor simultaneously drives the centralized transmission synchronous belts in multiple profiles to rotate. The centralized transmission synchronous belts then transmit power to each conveying group installed on the transmission profile, finally driving the conveying components on the conveying group to rotate, thereby realizing the conveying of glass. This structure allows for the selection of the number and position of the conveying components, as well as the number and position of the conveying components on the conveying components, according to the size of the glass being processed, avoiding idle power in the conveying units and thus reducing the energy consumption of the entire equipment.

[0032] 2. For the main drive mechanism, the main drive shaft adopts a disconnected structure, and multiple main drive units are connected in series through couplings. In this way, when forming glass of different sizes, the number of main drive units can be increased or decreased, improving the adaptability of the equipment, and also avoiding power idleness in non-working areas, further reducing the energy consumption of the equipment.

[0033] 3. The conveying mechanism and the main drive unit are connected by a centralized synchronous belt. The centralized synchronous belt can be quickly engaged and disengaged by controlling the sliding of the slider through the transmission tensioning mechanism, thereby improving the speed of synchronous belt replacement and maintenance.

[0034] 4. The transmission profile is independently raised and lowered by the lifting mechanism, and multiple conveying components can be raised and lowered to different heights to adjust the shape of the conveying surface formed by the conveying components, so as to match the curved surface of the glass output from the pre-bending furnace, thereby improving the safety and reliability of pre-bent glass conveying.

[0036] 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.

[0037] See attached document Figure 1 As shown, a transmission and conveying device for automotive glass forming includes a conveying mechanism 1, a main transmission mechanism 2, a lifting mechanism 3, and a support beam 4. Two support beams 4 are provided and arranged perpendicular to the glass conveying direction, used to connect the device to a corresponding frame.

[0038] like Figure 2 , 3As shown, the conveying mechanism 1 includes a conveying assembly, a transmission profiles 12 spaced apart perpendicular to the glass conveying direction, and a transmission tensioning mechanism 13. The conveying assembly is divided into a first conveying assembly 11 and a second conveying assembly 15 depending on whether it is located inside a hollow mold. b first conveying assemblies 11 are selectively arranged above the transmission profiles 12 along the perpendicular to the glass conveying direction, where a ≥ b. Each first conveying assembly 11 has multiple first conveying units arranged along the length of the transmission profile 12. The first conveying unit includes a support frame 18 and first conveying components 17 symmetrically arranged on the left and right sides of the upper end of the support frame 18. The first conveying components 17 are rollers, wheels, etc., used to support and convey the glass to be formed. The second conveying assembly 15 is used to connect with the pre-bending furnace, for joining pieces of glass to be formed, and to deliver the glass to the first conveying assembly 11. The second conveying assembly 15 includes at least one second conveying unit, which includes a support frame 18 and second conveying components 19 installed on both sides of the support frame. The second conveying components can have the same structure as the first conveying components. Preferably, the second conveying assembly 15 further includes at least one third conveying unit. The third conveying unit includes a pair of support frames 18 and a third conveying member 110 positioned therebetween. The third conveying member 110 employs a long roller conveyor, the length of which is greater than the sum of the lengths of the two second conveying members 19 in the second conveying unit. The long roller conveyor allows for a larger contact area with the glass, ensuring the safety of the splicing process. Therefore, the second conveying assembly 15 may include only the second conveying unit or the third conveying unit, or it may include both.

[0039] According to the size of the glass to be formed, each conveying unit is installed at a predetermined position along the length of the transmission profile 12. The conveying component is fixed to the transmission profile 12 along its length by a support frame 18. The multiple first conveying units of the first conveying assembly 11 are arranged in a concentrated and dense manner, but the spacing between adjacent first conveying units is preferably such that it does not affect the rotation of each first conveying component 17 and the first conveying assembly 11 as a whole can move up and down from the center of the hollow mold. The second conveying assembly 15 is arranged away from the first conveying assembly 11, so that the second conveying assembly 15 is located outside the hollow mold to avoid interference with the hollow mold when the conveying mechanism 1 moves up and down.

[0040] Lifting connecting plates 14 are respectively provided at both ends of the transmission profile 12 for connecting with the lifting mechanism 3 to realize the overall lifting of the entire conveying mechanism 1. The lifting mechanism 3 can be a hydraulic cylinder, pneumatic cylinder or electric push rod, etc. The fixed part of the lifting mechanism 3 is fixed on the support beam 4, and the lifting part of the lifting mechanism 3 passes through the support beam 4 and is connected to the lifting connecting plate 14.

[0041] like Figure 3 , 4As shown, the transmission profile 12 has an open side mounting space 121. The mounting space 121 contains a centralized transmission synchronous belt 25 of the main transmission mechanism 2 and a centralized transmission pulley 24 for cooperating with the centralized transmission synchronous belt 25. The centralized transmission pulley 24 includes multiple support pulleys 241. A single power source drives a transition shaft 23, which in turn drives all the support pulleys 241 to operate synchronously through the centralized transmission synchronous belt 25, thereby realizing centralized distribution and management of the power source. The centralized transmission synchronous belt 25 extends from the opening on the lower surface of the transmission profile 12 and is connected to the transmission tensioning mechanism 13. The transmission tensioning mechanism 13 is used to ensure the tension of the centralized transmission synchronous belt 25 to adapt to the changes in distance between the conveyor mechanism 1 and the main transmission motor caused by the lifting and lowering of the conveyor mechanism 1.

[0042] Preferably, the transmission tensioning mechanism 13 includes a telescopic mechanism 131, a slider-rail assembly 132, and a tensioning synchronous pulley 133. The telescopic mechanism 131 can be an electric push rod, hydraulic rod, cylinder, etc.; in this embodiment, an electric push rod is used. The fixed end of the telescopic mechanism 131 is hinged to the lower surface of the transmission profile 12, and the telescopic end of the telescopic mechanism 131 is hinged to the slider in the slider-rail assembly 132. The slide rail of the slider-rail assembly 132 is fixed to the lower surface of the transmission profile 12, and the tensioning synchronous pulley 133 is rotatably mounted on the slider. The centralized transmission synchronous belt 25 of the main transmission mechanism 2 is wound around the tensioning pulley 133, and the slider is driven to slide linearly by the telescopic mechanism 131, ensuring that the centralized transmission synchronous belt 25 is tensioned before and after lifting and lowering the conveying mechanism 1, thereby ensuring reliable power transmission.

[0043] like Figure 5 As shown, the centralized transmission pulley 24 inside the transmission profile 12 includes a support pulley 241 supporting the upper layer of the centralized transmission synchronous belt 25 and a reversing pulley 242 located at both ends of the transmission profile 12 and at the opening on the lower surface of the transmission profile 12.

[0044] The support frame 18 has an internal cavity containing a conveyor transmission assembly, including a power input wheel, a power output wheel, and a transmission belt. The power input wheel is located at the bottom of the support frame 18 and is coaxially connected to the support pulley 241 on the open side of the transmission profile. The support pulley 241 drives the power input wheel one-to-one, and the transmission belt transmits the power to the power output wheel, which in turn drives a roller or roller conveyor coaxially mounted with the power output wheel. This allows for multi-point transmission of multiple conveyor components simultaneously driven by a centralized synchronous belt 25.

[0045] Preferably, the power input wheel and the support pulley 241 are integrated into a synchronous pulley and mounted on the transmission profile 12, which facilitates the quick connection or disconnection of the transmission belt on the support frame 18 with the centralized transmission synchronous belt 25.

[0046] Furthermore, the conveying mechanism 1 is also equipped with a photoelectric switch on the second conveying assembly 15 for detecting the glass position. The photoelectric switch 16 is located on one side of the roller conveyor of the second conveying assembly 15, preferably at the glass input end of the second conveying assembly 15.

[0047] Continue to refer to Figure 5 , Figure 7 As shown, the main transmission mechanism 2 also includes a main transmission motor 21, a power output shaft 22, a main transmission unit 26, and a coupling 27. The main transmission unit 26 includes a support 262, a short transmission shaft 261, and transition pulleys 263. The middle part of the short transmission shaft 261 is connected to the middle part of the support 262. A transition shaft 23 is provided on the upper part of the support 262. The short transmission shaft 261 and the transition shaft 23 are connected by a transmission wheel set inside the support 262, realizing the rotational drive of the short transmission shaft 261 on the transition shaft 23. The transition pulleys 263 are mounted on the transition shaft 23 and rotate with the transition shaft 23. The number of transition pulleys 263 can be determined according to the length of the transition shaft 23. In the main transmission mechanism 2, there are m transition shafts 23 and a transition pulleys 263, where 1 < m ≤ a. In this embodiment, each main transmission unit 26 is provided with four transition pulleys 263, and the transition pulleys 263 are symmetrically distributed on both sides of the support 262. Multiple main drive units 26 are fixed on the base of the main drive mechanism 2 along a direction perpendicular to the glass conveying direction. The short drive shafts 261 of adjacent main drive units 26 are connected together by couplings 27 to form a relatively long main drive shaft. The main drive shaft is connected to the power output shaft 22 of the main drive motor 21 via couplings 27. In this way, the main drive motor 21 can drive the short drive shafts 261 of each main drive unit 26 to rotate synchronously through the connection of couplings 27. The power is then transmitted to the transition shaft 23 by the transmission wheel set in the main drive unit 26, which drives the transition pulleys 263 on the transition shaft 23 to rotate. The centralized transmission synchronous belts 25 and the b transition pulleys 263 in the b transmission profiles 12 of the first conveying assembly 11 are connected one-to-one.

[0048] Figure 6 for Figure 5 A sectional view of the support of the main drive unit 26, by Figure 6 As shown, the transmission wheel assembly within the support 262 includes a first transmission wheel 2621, a second transmission wheel 2622, and a transmission tension wheel 2623. The first transmission wheel 2621 is connected to the short transmission shaft 261 by a key, and the second transmission wheel 2622 is connected to the transition shaft 23 by a key. The transmission tension wheel 2623 is used to adjust the tension of the transmission belt between the first transmission wheel 2621 and the second transmission wheel 2622.

[0049] In this embodiment, the transmission mechanisms within the main transmission mechanism 2, the main transmission mechanism 2 in relation to the conveying mechanism 1, and the support frame 18 of the conveying assembly all adopt synchronous belt mechanisms. In other embodiments, chain drive mechanisms can also be used instead.

[0050] 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.
