Abstract
Description
Technical Field
[0001] The present application relates to the field of glass manufacturing, and in particular to a lever-type float glass transition roller table tin wiping device. Background Art
[0002] Between the end of the tin bath and the annealing furnace, the transition roller table is responsible for supporting the glass from the tin bath and smoothly introducing it into the annealing furnace. Although the transition roller table is short, from the perspective of glass technology, it is actually a very critical stage for the glass to change from a plastic free state to an elastic frozen state. This short transition zone will affect the internal (stress structure) and external (surface performance) quality of the glass, affect the forming and annealing of the glass, and further affect the yield of the glass.
[0003] The transition roller table mainly includes a slag box, a sealing cover, a transition roller, a transmission part and a tin-wiping device. In the prior art, the surface quality of the transition roller table has a direct impact on the quality of the glass, because the glass will contact the surface of the transition roller when passing through the transition roller table, and the adhesive on the surface of the transition roller may scratch the lower surface of the glass. This requires that the tin-wiping device and the surface of the transition roller should maintain long-term contact and a certain pressure. If it is too tight, the transition roller will easily lock, and if it is too loose, the tin-wiping function will not be achieved.
[0004] The graphite strip in the tin-wiping device will be gradually worn after long-term friction with the transition roller, and the height of the graphite strip will decrease. In order to make the graphite strip closely contact with the surface of the transition roller, the height of the graphite strip needs to be raised. The commonly used method is to adjust the height of the graphite strip by adjusting the bolt. The number of mechanisms that need to be adjusted on a general transition roller table is 15 to 18. If the adjustment screw is used, the operation is very troublesome. Utility Model Content

[0030] The following is a further detailed description of a lever-type float glass transition roller tin wiping device proposed by the utility model in combination with the accompanying drawings and specific embodiments. The advantages and features of the utility model will become clearer according to the following description and claims.
[0031] See also Figures 1 to 4 This embodiment provides a lever-type float glass transition roller tin wiping device, including a roller body 1, a plurality of transition rollers 2 and a plurality of adjustment components; the transition rollers 2 are all arranged on the roller body 1, and the transition rollers 2 are arranged along the glass conveying direction. The adjustment components correspond to the transition rollers 2 one by one; the adjustment components include a graphite strip 3, a guide block 4, a push rod 5 and a counterweight. Among them, the guide block 4 is arranged on the roller body 1, and a guide groove is opened on the guide block 4, and the graphite strip 3 is located in the guide groove. The push rod 5 is arranged on the roller body 1, and the first end of the push rod 5 extends into the guide groove. The first end of the push rod 5 abuts against the graphite strip 3 and prompts the graphite strip 3 to press against the roller body 1; the counterweight is arranged on the roller body 1, and the counterweight is connected to the second end of the push rod 5, prompting the push rod 5 to push the graphite strip 3.
[0032] Furthermore, the axes of the transition rollers 2 are parallel to each other, and the transition rollers 2 are arranged in sequence. In the prior art, the roller table body 1 is located between the tin bath and the annealing furnace, so the glass conveying direction in this solution refers to the direction from the tin bath to the annealing furnace.
[0033] It is further arranged that the transition roller 2, the guide block 4 and the push rod 5 are arranged in sequence from top to bottom.
[0034] The tin wiping device can quantify the force of the push rod 5 through the counterweight part, so that the push rod 5 is always in contact with the graphite strip 3, and then the graphite strip 3 is pressed against the transition roller 2, which can effectively and conveniently make the graphite strip 3 fit the roller surface; this structure can ensure that the graphite strip 3 is in close contact with the roller surface at all times without excessive friction causing abnormal rotation of the roller, and its structure is simple, easy to operate and easy to maintain.
[0035] The specific structure of the lever-type float glass transition roller two tin-wiping devices of this embodiment is further described below:
[0036] In this embodiment, the counterweight part includes a connecting rod 6, an adjusting rod 7 and a counterweight block 8; the connecting rod 6 is rotatably connected to the roller platform body 1, the first end of the connecting rod 6 is rotatably connected to the first end of the adjusting rod 7, the second end of the adjusting rod 7 is rotatably connected to the second end of the push rod 5, and the counterweight block 8 is arranged at the second end of the connecting rod 6.
[0037] To further explain, the second end of the push rod 5 is the end of the push rod away from the transition roller 2 .
[0038] Further explanation, the implementation process of the counterweight part is: the staff adjusts the gravity on the second end of the connecting rod 6 through the counterweight block 8, and the second end of the connecting rod 6 moves downward, which will drive the first end of the connecting rod 6 to move upward, and then push the push rod 5, and the push rod 5 acts on the graphite strip 3, and the graphite strip 3 achieves the effect of pressing against the transition roller 2. The function of the adjustment rod 7 is to enable the push rod 5 to move up and down stably without getting stuck.
[0039] In this embodiment, the push rod 5 is vertically arranged, and the counterweight portion is located below the transition roller 2 .
[0040] In this embodiment, the second end of the connecting rod 6 is rotatably connected to the supporting rod 9 , and a containing plate 10 is fixed to one end of the supporting rod 9 away from the connecting rod 6 , and the counterweight 8 is located on the containing plate 10 .
[0041] It is further explained that the placing plate 10 makes it more convenient to adjust the counterweight 8 .
[0042] In this embodiment, the weight of the counterweight 8 is W, and the value range of W is [100, 150] Kg.
[0043] In this embodiment, a plurality of guide columns 11 are provided on the roller platform body 1, and the guide columns 11 correspond to the transition rollers 2 one by one, and the guide columns 11 are located between the corresponding transition rollers 2 and the counterweight part; wherein, a mounting groove is opened at one end of the guide block 4 facing the transition roller 2, the guide block 4 is located in the mounting groove, and the push rod 5 is located in the guide column 11, and the second end of the push rod 5 extends outward and is connected to the counterweight part.
[0044] Further, the guide column 11 is vertically arranged and fixed on the roller table body 1 , and the guide block 4 is embedded in one end of the guide column 11 ; of course, in order to facilitate observation of the graphite strip 3 , the guide block 4 can protrude from the guide column 11 .
[0045] In this embodiment, a slag box 13 and a cover body 14 are provided on the roller platform body 1. The slag box 13 is located below the transition roller 2. The cover body 14 matches the slag box 13 to form a sealed space. The transition roller 2 is located in the sealed space, and both ends of the transition roller 2 extend out of the sealed space. A plurality of bearing seats 12 are provided on the roller platform body 1. The bearing seats 12 are all located at one end of the corresponding transition roller 2, and both ends of the transition roller 2 are provided on the corresponding bearing seats 12.
[0046] In the prior art, the end of the transition roller 2 is usually close to the sealed space, but due to the high temperature in the sealed space, a water cooling jacket must be added to the end bearing of the transition roller 2 to reduce the bearing operating temperature. The bearing is water-cooled, and the cooling water pipeline system is in a long-term high-temperature environment, which often leaks, causing damage to the transition roller 2; in addition, the transition roller 2 must be replaced regularly. Due to the influence of the cooling water pipe, it is inconvenient to disassemble the transition roller 2, and the replacement time of the transition roller 2 is extended. The longer the replacement time of the transition roller 2 is, the greater the impact on the glass ribbon transmission. If the operation is improper, it will cause the glass plate to break, causing huge losses to production.
[0047] In this solution, the installation position of the bearing seat 12 is changed, and the bearing seat 12 is away from the sealed space. On the one hand, the problem of excessively high ambient temperature of the bearing seat 12 is solved, the service life of the bearing is extended, and the space environment for bearing maintenance is improved; on the other hand, the transition roller 2 is supported separately, and the slag box 13 is no longer used as a support, so as to avoid deformation of the transition roller 2 caused by deformation of the lower slag box 13 under high temperature.
[0048] In this embodiment, an observation window is provided on the cover body 14. A gas pipeline extending into the observation window is provided on the roller platform body 1 for introducing inert gas to reduce the possibility of gas overflowing from the sealed space.
[0049] Furthermore, there is an observation window on the side of the transition roller cover 14. Under normal circumstances, the observation window is closed, but under special circumstances, the observation window needs to be opened. At this time, cold air in the surrounding environment will enter the transition roller 2, destroying the atmosphere in the transition roller 2 and affecting production. Therefore, nitrogen with a certain pressure (slightly higher than the pressure of air) is introduced into the sealed mine near the observation window to prevent the entry of cold air.
[0050] The above is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they still fall within the protection scope of the present invention.
