Description

Technical Field

[0001] This invention relates to the field of glass manufacturing technology, and in particular to a polishing mechanism, an annealing furnace roller polishing device, and an annealing furnace roller polishing method. Background Technology

[0002] In continuous production lines for float glass and photovoltaic glass, the annealing furnace roller conveyor is a crucial process. As the core support and transmission component of this system, the surface condition of the annealing roller directly determines the quality of the glass product. Under long-term high-temperature, high-load operating conditions, the roller surface is highly susceptible to problems such as condensation of glass volatiles, oxide scale formation, minor scratches, and even deformation. These surface defects are directly transferred to the softened underside of the glass sheet at high temperatures, causing quality defects such as optical distortion, pitting, and continuous scratches, severely impacting product grade, yield, and market value.

[0003] Currently, the maintenance of annealing rolls mainly relies on traditional offline processing methods. This method requires the online removal of the annealing rolls, disassembling and transporting each roll to a specific maintenance site for manual or semi-mechanical grinding and polishing. This method has many drawbacks: First, changing rolls on the production line results in direct output loss, disrupting production plans and significantly impacting economic efficiency; second, disassembling and installing rolls is a heavy and dangerous operation, requiring high skill levels, involving high labor intensity, and posing safety hazards; third, the alignment accuracy of the offline polished rolls during reinstallation may be problematic, potentially causing new operational malfunctions. Japanese patent document JPS60190557U discloses a conveyor roller polishing device, which includes sandpaper, a sandpaper pressing member, and a retainer. The retainer fixes the sandpaper pressing member, which presses the sandpaper to polish the conveyor roller. However, its function is often relatively simple, or it can only perform simple cleaning and cannot achieve fine polishing; or its structure is complex and has poor adaptability, making it difficult to promote its application on production lines of different specifications. A more common problem is that these devices lack effective temperature control and sealing measures. The heat generated during the polishing process may cause local stress changes in the roller, and the resulting grinding debris can easily contaminate the kiln environment and even damage the glass products.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] The technical problem to be solved by this invention is to solve the problem of poor online polishing effect of annealing rollers.

[0006] The present invention solves the above-mentioned technical problems through the following technical means: This invention claims protection for a polishing mechanism, including a frame, a linear drive structure, a water tank, and a polishing structure; the linear drive structure is provided inside the frame, and the linear drive structure forms a sliding guide engagement with the frame along the length of the frame; one end of the water tank is provided at the output end of the linear drive structure, and the other end of the water tank is provided with a polishing structure, the polishing structure including a polishing surface that slides circumferentially.

[0007] The linear drive structure drives the rotating surface to move along the axial direction of the annealing roller, while the polishing surface slides circumferentially to polish the surface of the annealing roller.

[0008] Preferably, the polishing structure includes at least two polishing wheels, a rotating shaft, a second transmission unit, and a polishing belt. At least two polishing wheels are connected to one end of the water tank. The at least two polishing wheels are symmetrically arranged along the width direction of the water tank. A polishing belt is fitted on the at least two polishing wheels. The outer surface of the polishing belt forms a polishing surface, and the surfaces of two adjacent polishing wheels form a rotating surface. The rotating shaft is connected to the inner part of the water tank. A second transmission unit for synchronous transmission is provided between the rotating shaft and any polishing wheel. The second transmission unit passes through the water tank.

[0009] Only one polishing wheel needs to be connected to the second transmission unit. By inputting power to one end of the rotating shaft, the polishing wheel can be rotated, driving the polishing belt to polish the annealing roller.

[0010] Preferably, the linear drive structure includes a rack, a connecting plate, a first motor, and a gear. The rack is arranged inside the frame along the length of the frame. The connecting plate is arranged inside the frame, and the first motor is arranged on the connecting plate inside the frame. The output shaft of the first motor is connected to the gear, and the gear meshes with the rack. The water tank is arranged on the connecting plate outside the frame.

[0011] Preferably, the frame is a T-shaped slide rail, and the T-shaped slide rail and the connecting plate form a sliding guide fit along the length of the T-shaped slide rail.

[0012] The T-shaped slide rail and the connecting plate slide together to guide the water bag when it moves. The water bag and the top of the T-shaped slide rail work together to prevent the water bag from flipping or slipping during sliding.

[0013] Preferably, it also includes a cooling water circulation passage, wherein the cooling water circulation passage is provided inside the water tank, and the cooling water circulation passage winds around the length of the water tank at least once.

[0014] The arrangement and number of cooling channels are not limited, but they must extend at least one full circle along the length of the water tank to ensure proper cooling of the shaft. Additionally, the cooling channels must be staggered from the second sprocket to prevent scratching and damage.

[0015] This invention claims protection for an annealing kiln roller polishing device employing a polishing mechanism, including a stop mechanism and a polishing mechanism. The stop mechanism is provided on the annealing kiln wall, and a space is provided through the stop mechanism for the annealing roller neck and water bath to pass through. The annealing roller is in contact with the polishing surface.

[0016] Introducing two stops offers two advantages. First, the moving water bath provides guidance and support, ensuring the polishing wheel remains in close contact with the annealing roller, improving polishing efficiency and cleanliness. Second, when the polishing mechanism extends into the annealing furnace, the two stops maintain a sealed environment, ensuring temperature control and preventing heat from causing localized stress changes on the rollers. This also prevents grinding debris from contaminating the furnace environment and potentially damaging the glass products.

[0017] Preferably, the stop mechanism includes at least two symmetrical stops, each of which has at least two slots on its adjacent surfaces, and the at least two slots interlock to form a space.

[0018] Preferably, the slot located on the upper side of the adjacent surface of the stop block is defined as the first slot, and the first slots are aligned with each other to form a first space for transition and cooperation with the neck of the annealing roller.

[0019] The first space not only supports the annealing rollers, but also matches their shape, which allows the annealing furnace to remain sealed.

[0020] Preferably, the slot located on the lower side of the adjacent surface of the stop is defined as the third slot, and the third slots are aligned with each other to form a second space that slides with the water bag.

[0021] The second space not only supports and guides the water tank, but also keeps the annealing furnace sealed.

[0022] This invention claims protection for an annealing kiln roller polishing method using an annealing kiln roller polishing apparatus, comprising the following steps: The annealing roller neck and water bath pass through the space, and a baffle mechanism is installed on the annealing kiln wall; The annealing roller rotates, activating the polishing structure. The rotating surface polishes around the annealing roller, and the linear drive structure drives the rotating surface to move axially along the annealing roller.

[0023] The advantages of this invention are: by integrating the cooling channel inside the water tank, it can effectively cool the rotating shaft and simultaneously cool the annealing rollers during conveying and grinding. The overall structure is compact and rationally arranged, achieving the dual advantages of functional integration and space optimization. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1 See Figure 1 and Figure 2 This embodiment requires protection of the polishing mechanism for online polishing of the annealing roller b. The polishing mechanism includes a frame 40, a wheel structure 41, a rack 42, a connecting plate 43, a first motor 44, a gear 45, a water tank 46, a second motor 47, a rotating shaft 48, a mounting plate 49, a bracket 50, a polishing wheel 51, a first sprocket 52, a second sprocket 53, a chain 54, and a polishing belt 55.

[0027] The frame 40 serves as the mounting reference for the entire mechanism, and a wheel structure 41 is provided at its bottom to facilitate the movement of the frame 40, which is existing technology. The frame 40 is a T-shaped slide rail, and racks 42 are provided on one side of the bottom inner wall of the frame 40 along the length of the frame 40. The racks 42 and the wheel structure 41 are staggered.

[0028] The frame 40 is not limited to a T-shaped slide rail; it can also be a dovetail-shaped slide rail, as long as it provides a certain guiding function. Alternatively, it can be a U-shaped or square slide rail, with additional guiding structures provided, all of which serve as protection in this embodiment.

[0029] The connecting plate 43 is partially slidably fitted within the frame 40. A first motor 44 is mounted on one side of the connecting plate 43 within the frame 40. A gear 45 is coaxially mounted on the first motor 44 and its output shaft. The axis of the gear 45 is vertical, and the gear 45 meshes with a rack 42. A water tank 46 is mounted on the connecting plate 43 outside the frame 40. The water tank 46 is a hollow, elongated box structure, with its long side parallel to the long side of the frame 40. A water inlet 460 and an outlet 461, both connected to a cooling source and a power source (not shown in the figure), are located on one side of the top of the water tank 46. A cooling channel (not shown in the figure) winds inside the water tank 46. The power source is typically a water pump. The two ends of the cooling water circulation channel are connected to the water inlet 460 and the outlet 461, respectively, forming a complete cooling water circulation path, which is existing technology.

[0030] See Figure 3 and Figure 4 and Figure 5 A second motor 47 is installed at one end of a water tank 46. A rotating shaft 48 is connected inside the water tank 46, with its axis parallel to the long side of the water tank 46. One end of the rotating shaft 48 is connected to the output shaft of the second motor 47. A mounting plate 49 is connected to the top of the other end of the water tank 46. Two brackets 50 are bolted to the mounting plate 49. The two brackets 50 are symmetrically arranged along the width of the mounting plate 49. Both brackets 50 have a U-shaped frame structure, and polishing wheels 51 are mounted on each bracket. The axis of the polishing wheels 51 is parallel to the long side of the water tank 46. Polishing belts 55 are fitted onto the two polishing wheels 51. A first sprocket 52 is coaxially mounted at one end of each polishing wheel 51. A corresponding perforation is made on the surface of the water tank 46. A second sprocket 53 is coaxially mounted on the rotating shaft 48. A chain 54 meshes with the second sprocket 53, passing through the perforation and engaging with the first sprocket 52.

[0031] The arrangement and number of cooling channels are not limited, but they must extend at least one full circle along the length of the water tank 46 to ensure cooling of the rotating shaft 48. Additionally, the cooling channels must be staggered from the second sprocket 53 to prevent scratching and damage.

[0032] In this embodiment, during operation, the frame 40 and wheel structure 41 ensure that the polishing mechanism moves to the position of the annealing roller b; then, with the meshing of the rack 42 and gear 45, the water tank 46 can slide along the length direction of the frame 40, so that the water tank 46 extends and drives the polishing wheel 51 to move axially along the annealing roller b; at the same time, the first sprocket 52 and chain 54 mesh, so that the polishing belt 55 on the polishing wheel 51 polishes the surface of the annealing roller b.

[0033] Therefore, by rubbing the polishing belt 55 circumferentially along the annealing roller b and moving it axially along the annealing roller b, a full coverage of the annealing roller b is achieved, resulting in uniform polishing. The entire process does not require disassembling the annealing roller b, nor does it affect the conveying and production of the annealing roller b itself. The polishing operation can be completed online, ensuring both the comprehensiveness and consistency of the polishing, and completely avoiding production interruptions caused by disassembly and maintenance. This design significantly improves the continuous operation efficiency of the equipment, reduces maintenance costs, and also helps extend the service life of the annealing roller b, while ensuring the stability of the surface treatment quality of the sheet material.

[0034] Furthermore, the cooling channel is integrated inside the water tank 46, which can effectively cool the rotating shaft 48. The overall structure is compact and reasonable, achieving the dual advantages of functional integration and space optimization.

[0035] Example 2 See Figure 6 and Figure 7 This embodiment, based on Embodiment 1, requires protection of the annealing kiln roller polishing device, including a left stop block 1, a right stop block 2, a ceramic fiber blanket 3, and a polishing mechanism. The walls of the annealing kiln a on both sides of the annealing roller b are respectively connected to the left stop block 1 and the right stop block 2 by screws. The left stop block 1 and the right stop block 2 have the same shape and structure. The left stop block 1 and the right stop block 2 have a first groove 10 and a third groove 12 on their sides. The first groove 10 has a semi-circular groove structure, and the third groove 12 has a square groove structure. The third groove 12 and the first groove 10 are not connected to each other.

[0036] Left stop 1 and right stop 2 are arranged symmetrically along the annealing roller b and are joined together so that the first slot 10 is joined to form a first space for accommodating the neck of the annealing roller b, and the third slot 12 is joined to form a second space that slides with the water tank 46. A ceramic fiber blanket 3 is pressed at the joint for sealing.

[0037] In actual use, the ceramic fiber blanket 3 can also be replaced with a ceramic fiber pad, which can also achieve the same sealing effect. Therefore, the material is not limited.

[0038] In this embodiment, the introduction of two stops offers two advantages. First, the water bath 46's movement provides guidance and support, ensuring the polishing belt 55 on the polishing wheel 51 remains in close contact with the annealing roller b, improving polishing efficiency and cleanliness. Second, when the two stops extend into the annealing furnace a during polishing, the furnace a remains sealed, ensuring temperature control and preventing heat from causing localized stress changes on the rollers. This also prevents the generated grinding debris from contaminating the furnace environment or even damaging the glass products.

[0039] Example 3 This embodiment, based on Embodiment 2, requires the provision of a method for polishing roller a in an annealing furnace, specifically including the following steps: First, move the frame 40 to the side of the annealing roller b, so that the polishing mechanism extends along the axial direction of the annealing roller b to the underside of the annealing roller b.

[0040] Next, install the left stop 1 and the right stop 2 so that they fit together, with the first space engaging at the neck of the annealing roller b and the second space engaging at the water tank 46.

[0041] Then, the first motor 44 is started, causing the gear 45 to mesh with the rack 42, which drives the connecting plate 43 to move along the frame 40, further driving the water tank 46 to move along the frame 40, that is, the polishing wheel 51 moves along the annealing roller b axial direction; at the same time, the second motor 47 is started, driving the rotating shaft 48 to rotate, and the first sprocket 52 meshes with the chain 54, causing the polishing wheel 51 to drive the polishing belt 55 to contact and polish the surface of the annealing roller b. Simultaneously, the cooling water circulation passage cools the rotating shaft 48.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
