Description

Technical Field

[0001] The utility model relates to the technical field of float glass production, in particular to an annealing roller cleaning device for float glass production. Background Art

[0002] During the production of float glass, tin slag marks are a common quality problem. It refers to irregular spots or stripes caused by tin slag on the lower surface of the glass plate. These defects not only affect the appearance quality of the glass, but may also affect the optical and mechanical properties of the glass. There is no cleaning device for the annealing roller in the ordinary float glass annealing furnace. When tin oxide impurities adhere to the annealing roller, the glass scrap rate will be very high. In order to ensure the quality of the glass plate, the annealing roller must be replaced, or the annealing roller must be pulled out for polishing before replacement. However, the operation is very time-consuming and labor-intensive, and the site temperature is high and the labor intensity is high.

[0003] In order to improve the above problems, after searching, the patent publication number CN115889257A provides a high-end float glass production line annealing roller cleaning device, including a working support, the working support is horizontally rotatably mounted with an annealing roller, and the working support is provided with a cleaning component for cleaning the surface of the annealing roller; the cleaning component includes a U-shaped plate and a graphite bar, a base is installed on the working support, a support rod is fixedly arranged on the base, and the U-shaped plate is horizontally arranged and fixedly installed on the support rod. Through the setting of the driving member, the driving member can drive the pad and the graphite bar to move upward, so that the graphite bar moves upward until it is pressed against the surface of the annealing roller. During the pressing contact process, the graphite bar can wipe and remove impurities such as tin oxide attached to the surface of the annealing roller, and the wiping and removal effect is good. During the normal use of the annealing roller, the surface of the annealing roller is treated to remove impurities without delaying the production progress.

[0004] Based on the above search and in combination with the prior art, it is found that due to the long length of the annealing roller, it is difficult for the annealing roller cleaning device similar to the above disclosed in the prior art to collect the impurities cleaned by the annealing roller, which makes the subsequent cleaning more troublesome. Therefore, an annealing roller cleaning device for float glass production is proposed to improve the above problem. Utility Model Content
