Abstract
Description
Technical Field

[0002] Float glass is a flat glass produced by the float process, which has a wide range of uses and broad market prospects. In the production process of float glass, the forming link is particularly critical: in the tin bath with protective gas, the molten glass flows continuously from the tank kiln and floats on the surface of the relatively dense tin liquid; thanks to the precise balance of gravity and surface tension, the glass liquid gradually expands and flattens on the surface of the tin liquid, and is thinned or thickened to a suitable thickness, and finally solidified into a glass ribbon; after cooling, the glass ribbon is led onto the transition roller table, and driven by the rollers of the roller table, it is sent to the annealing kiln for annealing.
[0003] During the process of thinning, accumulating thickness and annealing, the edges of the glass ribbon are prone to deformation, such as thinning, bending, and wrinkling. The thinner the glass, the more obvious the deformation. The deformation makes the edges uneven, uneven in strength, and easy to be damaged. At the same time, due to factors such as the temperature of the tin liquid, the lateral temperature difference of the float glass ribbon in the tin bath, and the deviation of the transition roller table or the annealing furnace roller, the glass ribbon is prone to plate swing. The rollers used to transport the glass ribbon in the F area of most float glass production lines are ring rollers. There are gaps between the multiple roller rings on the ring roller. When the glass ribbon is swaying, the deformed edge of the glass ribbon is easily blocked by the side of the roller ring, causing the glass ribbon to explode or crack longitudinally, seriously affecting the glass quality and production stability, resulting in low production efficiency.

[0027] The utility model discloses a glass ribbon edge supporting device and a ring roller, which solves the technical problem that when the glass ribbon has a plate swing phenomenon, the edge of the glass ribbon is easily blocked by the side of the ring roller, causing damage to the glass ribbon and thus resulting in low production efficiency.
[0028] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0030] Unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
[0031] See also Figures 1 to 3, Embodiment 1 of the present utility model provides a glass ribbon edge support device, which is used to be arranged between adjacent roller rings 21 on the ring roller of a glass production line;
[0032] The glass ribbon edge supporting device comprises a supporting ring 11;
[0033] The outer diameter of the support ring 11 is equal to the outer diameter of the roller ring 21;
[0034] The width of the outer ring surface of the support ring 11 is equal to the distance between adjacent roller rings 21 .
[0035] It can be understood that the roller ring 21 of the ring roller is generally an annular cylinder having an outer ring surface, an inner ring surface and left and right side surfaces; the support ring 11, the roller ring 21 of the ring roller and the roller shaft 22 are coaxially arranged, and the outer ring surface of the support ring 11 and the outer ring surface of the roller ring 21 are on the same closed curved surface; after the support ring 11 is installed between adjacent roller rings 21, it can fill the space between the adjacent roller rings 21 to ensure that the glass ribbon passes through the roller smoothly.
[0036] The device has been put into actual production. After years of use and acceptance, it avoids the contact between the edge of the glass ribbon and the side of the roller ring 21. It can solve the problem of edge breakage and plate explosion caused by the edge of the glass ribbon being blocked by the side of the roller ring 21 after the glass ribbon swings, effectively improving the glass production efficiency. For example, in a glass production line, when the glass ribbon width is 4200mm and the plate swing amplitude on both sides is greater than 40mm, the edge of the glass ribbon is often blocked by the roller ring and causes plate explosion, which makes process control difficult. After adding the device, the above problems are significantly improved, and the production stability is greatly improved. In addition, the device can be fully applied to other rollers with similar structures for conveying glass ribbons and related production environments.
[0037] Furthermore, in order to facilitate installation and disassembly, the support ring 11 is a detachable split circular ring. The support ring 11 may include two or more ring segments, each of which can be disassembled independently. The technicians can install the glass ribbon edge support device on the ring roller according to the actual glass ribbon plate swing position range at the production site without stopping the machine; the connection between the segments can be provided with a connection component to enhance the connection stability between the segments.
[0038] In a specific embodiment, the support ring 11 includes two half rings; a magnetic block 12 is installed at the connection surface of the half ring. The connection surface of the half ring refers to the connection surface where two half rings are connected to form a complete ring; the magnetic block 12 can be embedded or covered on the connection surface of the half ring, or other installation methods that can ensure the annular integrity of the support ring 11, so that the two half rings can be tightly connected by suction; the magnetic block 12 can be fixed by fastening screws, welding, embedding grooves, bonding, etc., preferably fixed by fastening screws 13, the magnet has suction force on the fastening screws 13, and the stability is higher; the half ring can be made of ferromagnetic material, the magnetic block 12 is not easy to fall off after installation, and carbon steel is preferably used, which has high wear resistance and is easy to be processed into various shapes; in order to prevent the two half rings from separating when the ring roller is running, the magnetic block 12 is preferably a strong magnetic block.
[0039] In order to fix the roller ring 21 so that it does not move relative to the roller shaft 22, a fixing pin 23 is generally fixed on the roller shaft 22. The fixing pin 23 is partially inserted into the roller ring 21 and partially fixed on the surface of the roller shaft 22 outside the roller ring 21. After the support ring 11 is installed, its inner ring surface cannot completely fit with the surface of the roller shaft 22 between adjacent roller rings 21. Moreover, since the sizes of the fixing pins 23 are usually not uniform, if only an avoidance space is provided on the inner ring surface of the support ring 11, it cannot be guaranteed that the avoidance space can meet the sizes of different fixing pins 23, making the applicability of the glass ribbon edge support device poor. Therefore In a preferred embodiment, the glass ribbon edge support device provided by the utility model also includes a gap column 14 arranged on the inner side of the support ring 11. The number of the gap columns 14 is multiple, and the multiple gap columns 14 are evenly distributed on the inner side of the support ring 11 along the circumference of the support ring 11; the position of the gap column 14 is staggered with the fixing pin 23. The gap column 14 can be used to enable the support ring 11 to avoid the fixing pin 23 and hold the roller shaft 22, thereby offsetting the gap caused by the fixing pin 23. After the glass ribbon edge support device is installed as a whole, the outer diameter of the support ring 11 is the same as the outer diameter of the roller ring 21, thereby ensuring that the glass ribbon passes through the roller smoothly.
[0040] More preferably, the side of the gap column 14 that contacts the roller shaft 22 of the ring roller is an arc surface that matches the surface of the roller shaft 22, which is beneficial for the glass ribbon edge support device to hold the roller shaft 22 tightly, and increases the friction between the glass ribbon edge support device and the roller shaft 22, reducing the possibility of relative rotation between the glass ribbon edge support device and the roller shaft 22.
[0041] See also Figure 3 , Embodiment 2 of the present utility model provides a ring roller for conveying a glass ribbon 3, the ring roller comprising a roller shaft 22, a plurality of roller rings 21 and a plurality of glass ribbon edge supporting devices as described in any one of the above items;
[0042] Glass ribbon edge supporting devices are provided between the roller rings 21 on the ring roller that may contact the side edge of the glass ribbon 3 or on both sides of the roller rings 21 .
[0043] It should be noted that the ring roller provided in this embodiment can be used in production and processing environments such as the annealing furnace F zone and transition roller table of a float glass production line that require the transportation of a glass ribbon, wherein a graphite ring roller is usually used in the annealing furnace F zone; glass ribbon edge support devices need to be provided near both sides of the glass ribbon 3 on the ring roller to prevent the edges of the glass ribbon 3 from being blocked by the side of the roller ring 21, and the specific number of glass ribbon edge support devices can be set according to the actual swing amplitude and swing position range of the glass ribbon 3 at the production site.
[0044] The above is a detailed introduction to a glass ribbon edge support device and a ring roller provided by the present invention. For a person skilled in the art, according to the idea of the embodiments of the present invention, there may be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
