Description

Technical Field

[0001] The utility model relates to the field of glass production, in particular to an online cleaning device for a calendering upper roller. Background Art

[0002] Solar cell modules require patterned glass to be encapsulated on the front or both sides of the solar cell. Patterned glass is produced using the calendering process, where high-temperature molten glass is pressed and stretched between the upper and lower rollers of a calender. Generally, both rollers are engraved with patterns.

[0003] Because the upper and lower calendering rollers are affected by the gas and glass liquid composition in the glass melting furnace for a long time, a layer of white oxide will adhere to the surface of the calendering rollers that are cooled by water after a long period of operation. When the upper and lower calendering rollers are partially detached during operation, they will leave marks on the glass plate surface, seriously affecting the quality of the glass. At this time, the calendering rollers need to be washed.

[0004] At present, there are two main ways to clean the calender upper roller. One is to manually wash the calender upper roller. This washing method requires the cooperation of at least 5 people. The temperature is high when washing the roller, the work intensity is high, and it takes about 20 minutes to wash the roller once, which seriously affects normal production. In addition, the roller is easily damaged when washing the roller, and improper speed control of the roller washing gun will lead to missed washing. The roller needs to be washed multiple times, and the washing effect is poor. The other is to use an online cleaning device to clean the calender upper roller. For example, Chinese patent CN104668225A discloses an online cleaning device for the calender upper roller of a glass calender. The patent installs the online cleaning device on the base of the calender through a U-shaped card slot. The distance here is close to the calender upper roller, and the working environment temperature is high (nearly 1000°C). The material requirements of the cleaning device are high (high temperature resistant material), resulting in high cost. In addition, the cleaning device adopts a fixed multi-nozzle group structure, which disperses the water pressure and is inconvenient for later maintenance. Utility Model Content
