Description

Technical Field

[0001] This application belongs to the technical field of float glass production, and more specifically, relates to a glass conveying device and glass production equipment. Background Technology

[0002] Glass conveying devices are one of the key pieces of equipment in a float glass production line. They are mainly used to transport the formed glass sheets between different production stages. For example, the glass conveying device is located between the tin bath and the annealing furnace, and is responsible for smoothly conveying the formed glass sheets in the tin bath to the annealing furnace for cooling.

[0003] Glass conveying devices typically consist of a base and rollers rotatably connected to the base. The rotation of the rollers conveys the glass sheets. However, due to the harsh environment of high temperature and humidity, coupled with the weight of the glass sheets and the continuous load, the rollers are prone to various malfunctions, such as gear tooth loss and clutch jamming. These malfunctions not only affect production efficiency but also damage the surface of the glass sheets, resulting in quality problems such as chrome scratches, burrs, and tin adhesion. Regular maintenance and replacement of the rollers are necessary.

[0004] Currently, when maintaining and replacing the rollers in the glass conveying device, the entire glass production line needs to be shut down. The maintenance time is long, a large amount of waste is generated during the shutdown process, which increases production costs and poses significant safety hazards. Utility Model Content

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0037] In a first aspect, embodiments of this application provide a glass conveying device, such as... Figure 1 and Figure 2 As shown, the glass conveying device includes a frame 100, a conveying mechanism 200, and a lifting mechanism 300. Both the conveying mechanism 200 and the lifting mechanism 300 are mounted on the frame 100. The frame 100 can be a frame structure, and both the conveying mechanism 200 and the lifting mechanism 300 can be mounted above the frame 100, providing stable support for them. The conveying mechanism 200 is used to carry and convey glass plates 400. Multiple conveying mechanisms 200 should be provided, arranged at intervals along a first direction to convey glass plates 400 along that direction. Optionally, the first direction is horizontal, meaning the multiple conveying mechanisms 200 convey glass plates 400 horizontally. The number of lifting mechanisms 300 can be one or more. The lifting mechanism 300 is located between two adjacent conveying mechanisms 200. It is used to lift the glass plate 400 upward when needed, and continue to convey the glass plate 400 after lifting it from the conveying mechanism 200. This allows for the maintenance and replacement of the conveying mechanism 200 below the glass plate 400 without affecting the normal conveying of the glass plate 400.

[0038] The conveying mechanism 200 may include a first base 210 and conveying rollers 220 disposed on the first base 210. Specifically, the first base 210 may be a vertically arranged column or frame, and the bottom of the first base 210 may be fixed to the frame 100 by bolts or other fasteners. The axis of the conveying rollers 220 is perpendicular to the first direction and is rotatably connected to the top of the first base 210 through bearings, for supporting the glass plate 400, and realizing the conveying function of the glass plate 400 by the rotation of the conveying rollers 220. The conveying rollers 220 may be made of graphite material to have high temperature resistance and wear resistance, be able to withstand the high temperature environment during the forming of the glass plate 400, and reduce friction loss. The conveying rollers 220 in the multiple conveying mechanisms 200 should be of the same height to ensure that the glass plate 400 remains horizontal during the conveying process and avoid bumps or jamming due to height differences.

[0039] like Figure 3 and Figure 4As shown, the lifting mechanism 300 may include a second base 310, a roller bracket 320, a support roller 330, and a lifting assembly 340. The second base 310 is mounted on the frame 100, the roller bracket 320 is located above the base, the support roller 330 is disposed on the roller bracket 320, and the lifting assembly 340 is disposed between the second base 310 and the roller bracket 320 for driving the roller bracket 320 to move up and down relative to the second base 310, so that the support roller 330 has a clearance position with a height lower than or level with the conveyor roller 220 and a lifting position with a height higher than the conveyor roller 220.

[0040] Specifically, the second base 310 can be a support structure of any shape and can be fixed to the frame 100 by bolts or other fasteners to facilitate the installation and maintenance of the entire lifting mechanism 300. Optionally, the second base 310 can be a C-shaped channel steel with the opening facing upwards to form a certain volume of accommodating space inside the second base 310, providing an installation position for the lifting assembly 340.

[0041] The idler bracket 320 can also be a support structure of any shape. The extending direction of the idler bracket 320 should be the same as the extending direction of the second base 310. The lifting assembly 340 is disposed between the idler bracket 320 and the second base 310, and the support roller 330 is disposed on the top of the idler bracket 320. Optionally, the idler bracket 320 can also be a channel steel with a C-shaped cross-section, with the opening of the channel steel facing downward, so as to form a cavity of a certain volume inside the idler bracket 320, which also provides an installation position for the lifting assembly 340.

[0042] The support roller 330 is mounted on the idler roller bracket 320 to support the glass plate 400 and continue to convey the glass plate 400 after it is lifted. The support roller 330 may include a mounting base 331, a support shaft 332, and a graphite sleeve 333. The mounting base 331 is connected to the idler roller bracket 320, the support shaft 332 is rotatably connected to the mounting base 331, and the axial direction of the support shaft 332 is parallel to the extension direction of the idler roller bracket 320. The graphite sleeve 333 is sleeved on the support shaft 332 to reduce friction loss during conveying by utilizing the heat resistance and wear resistance of the graphite sleeve 333.

[0043] The number of support rollers 330 can be multiple, and the multiple support rollers 330 are arranged at intervals along the extension direction of the roller bracket 320 so as to evenly distribute the weight of the glass plate 400, ensure the stability of the glass plate 400 during lifting and conveying, and prevent damage or deformation caused by uneven local stress.

[0044] The lifting assembly 340 drives the roller bracket 320 to move up and down, thereby changing the height of the support roller 330 on the roller bracket 320. When multiple conveying mechanisms 200 are used to convey glass plates 400, the support roller 330 should be in a clearance position, at which point the height of the support roller 330 is lower than or level with the conveying roller 220, so that the conveying roller 220 can be used to support and convey the glass plate 400. When the conveying mechanism 200 needs maintenance, the lifting assembly 340 drives the roller bracket 320 to move upward, causing the support roller 330 to move to a lifting position higher than the conveying roller 220. This allows the glass plate 400 to be lifted upward, moving under the action of the support roller 330. At the same time, the glass plate 400 is separated from the conveying mechanism 200, allowing maintenance and replacement of the conveying mechanism 200 without stopping the machine. The number of lifting components 340 can be one or more. For example, there can be two lifting components 340 arranged symmetrically on both sides of the second base 310 to provide a more stable support effect for the roller bracket 320.

[0045] In this way, the conveying mechanism 200 below the glass plate 400 can be repaired and replaced without affecting the normal conveying of the glass plate 400, greatly improving the reliability and stability of the equipment. At the same time, the design of the lifting component 340 also allows the roller support 320 to be lowered relative to the second base 310, so that the height of the support roller 330 is lower than or level with the conveying roller 220, so that the glass plate 400 can smoothly transition from the conveying mechanism 200 to the roller support 320.

[0046] like Figure 4 and Figure 5 As shown, in some embodiments, the lifting assembly 340 may include a first support rod 341, a second support rod 342, and a driving member. One end of the first support rod 341 is rotatably connected to the second base 310, and the other end is movably connected to the roller bracket 320; one end of the second support rod 342 is rotatably connected to the roller bracket 320, and the other end is movably connected to the second base 310; the first support rod 341 and the second support rod 342 intersect and are hinged to each other at the intersection; the driving member is connected to the first support rod 341 or the second support rod 342 to drive the first support rod 341 or the second support rod 342 to rotate.

[0047] The bottom end of the first support rod 341 is rotatably connected to the inner side of the second base 310 via a rotating shaft, and its top end is movably connected to the roller bracket 320. Specifically, as shown... Figure 6As shown, a slidable first sliding member 311 may be provided on the inner side of the second base 310. The first sliding member 311 may be a block structure with a cross-sectional shape matching the internal shape of the roller bracket 320. The first sliding member 311 may be slidably connected to the inner wall of the roller bracket 320 via a slide rail, pulley, or other structure. The end of the first support rod 341 facing away from the second base 310 is rotatably connected to the first sliding member 311, so that the first support rod 341 can slide along the roller bracket 320 while rotating. Optionally, the second base 310 may be provided with a first slide rail 312, and the first sliding member 311 may be slidably connected to the first slide rail 312.

[0048] The top end of the second support rod 342 can be connected to the inside of the roller bracket 320 via a pivot, and the bottom end is movably connected to the inside of the second base 310. Specifically, as shown... Figure 7 As shown, a slidable second sliding member 321 may be provided on the inner side of the roller bracket 320. The second sliding member 321 may be a block structure with a cross-sectional shape matching the internal shape of the second base 310, and is slidably connected to the inner wall of the second base 310 through a slide rail, pulley, or other structure. The end of the second support rod 342 facing away from the roller bracket 320 is rotatably connected to the second sliding member 321, so that the second support rod 342 can slide relative to the second base 310 while rotating. Optionally, the roller bracket 320 is provided with a second slide rail 322, and the second sliding member 321 is slidably connected to the second slide rail 322.

[0049] The intersection of the first support rod 341 and the second support rod 342 can be hinged together via a hinge shaft to allow relative rotation. Each lifting assembly 340 can have one or more first support rods 341 and second support rods 342. For example, there can be two first support rods 341 and two second support rods 342, with the two first support rods 341 and two second support rods 342 arranged axially at intervals along the hinge shaft, and the two second support rods 342 located between the two first support rods 341, to improve the structural strength of the lifting assembly 340.

[0050] A driving component can be disposed on the second base 310 and connected to the second sliding component 321 to drive the second sliding component 321 to move, thereby driving the first support rod 341 to rotate. When the driving component drives the second sliding component 321 to move, the second support rod 342 slides accordingly and rotates due to the restriction of the hinge shaft, simultaneously driving the first support rod 341 to rotate synchronously, thereby increasing or decreasing the distance between the ends of the first support rod 341 and the second support rod 342 on one side of the second base 310. When the distance between the ends of the first support rod 341 and the second support rod 342 on one side of the second base 310 increases, the roller bracket 320 lowers accordingly; conversely, when the distance decreases, the roller bracket 320 rises, thereby driving the support roller 330 to switch between a clearance position and a lifting position.

[0051] In addition, the driving component can also be disposed on the roller bracket 320 and connected to the first sliding member 311, so as to drive the second support rod 342 to rotate by driving the first sliding member 311 to move. Of course, the driving component can also be installed on both the second base 310 and the roller bracket 320 at the same time, so as to drive the first sliding member 311 and the second sliding member 321 to move simultaneously.

[0052] In some embodiments, when the driving member is installed on the second base 310, the driving member can be a driving screw 343, which is rotatably connected to the second base 310, and the second sliding member 321 is threadedly connected to the driving screw 343. Specifically, the driving screw 343 can be horizontally disposed inside the second base 310 and rotatably connected to the second base 310 through at least one bearing seat. The second sliding member 321 is provided with a threaded hole that matches the driving screw 343. The driving screw 343 passes through the threaded hole. By rotating the driving screw 343, the second sliding member 321 is driven to move along the second slide rail, thereby realizing the lifting and lowering movement of the first support rod 341 and the second support rod 342. In addition, the driving member can also be a cylinder, a hydraulic cylinder, or other power devices.

[0053] It is understandable that when there are two lifting components 340, the two drive screws 343 should operate simultaneously to drive the two lifting components 340 to move at the same time, so that the two sides of the roller support 320 can move upward smoothly. The lifting mechanism 300 may include a drive component 350 connected to both drive screws 343 simultaneously, so as to drive the two drive screws 343 simultaneously, thereby controlling the movement of the lifting components 340 on both sides at the same time, ensuring that the roller support 320 rises smoothly as a whole. Of course, it is also possible to set two drive components 350 respectively connected to the drive screws 343 on both sides, and use a synchronous control system to coordinate the operation of the two drive components 350 to ensure that the lifting components 340 on both sides move synchronously.

[0054] In some embodiments, the drive assembly 350 includes a connecting shaft 351 and a drive motor 352. The connecting shaft 351 is located between two lifting assemblies 340, and both ends of the connecting shaft 351 are respectively connected to the drive screw 343 on the corresponding side. The drive motor 352 is disposed on the second base 310 and connected to the connecting shaft 351, and is used to drive the connecting shaft 351 to rotate.

[0055] Specifically, the connecting shaft 351 can be horizontally set inside the second base 310. The two ends of the connecting shaft 351 are connected to the ends of the drive screws 343 on both sides through couplings, so as to synchronously drive the drive screws 343 on both sides by rotating the connecting shaft 351, thereby ensuring the synchronicity and stability of the lifting of the roller bracket 320 on both sides.

[0056] The drive motor 352 can be a variable frequency motor or a servo motor. The drive motor 352 can be fixed to the second base 310 by a support member and connected to the connecting shaft 351 by a transmission component. The transmission component can be a belt drive component, a chain drive component or a gear drive component, so that the drive motor 352 can drive the connecting shaft 351 to select, thereby simultaneously driving the drive screws 343 on both sides to rotate, so as to achieve the purpose of simultaneous operation of the lifting components 340 on both sides.

[0057] Secondly, this application also provides glass production equipment, such as... Figure 8 As shown, the glass production equipment includes the glass conveying device provided in the first aspect embodiment for conveying the glass sheet 400. For example, the glass production equipment may also include a tin bath 500 and an annealing furnace 600, with the glass conveying device disposed between the tin bath 500 and the annealing furnace 600 for conveying the glass sheet 400 formed in the tin bath 500 into the annealing furnace 600.

[0058] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
