AI Technical Summary
During the photovoltaic glass production process, the lubricating grease on the calendering roller journal dries into powder at high temperatures, causing the oil residue powder to fall onto the glass plate, resulting in stone defects and glass plate falling, increasing labor intensity and reducing production.
An oil-blocking and insulating water bag for the calendering roller journal is designed. By attaching the water bag to the outer side of the calendering roller shaft and letting water flow through it, the cooling water is circulated through the connecting water tank and the inlet and outlet water pipes, thereby increasing the heat exchange area, reducing the journal temperature, and preventing grease powder from splashing.
It effectively reduces the temperature of the calender roller journal, prevents grease powder from splashing onto the glass plate, reduces stone defects, improves production efficiency and reduces labor intensity.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of glass production, and specifically relates to an oil-blocking and water-insulating water bag for a calendering roller journal. Background Art
[0002] Because the photovoltaic glass calendering machine is exposed to high temperatures for a long time, the bearings need to be heated and lubricated with grease every week, causing the old grease to overflow on the journal. Under the high temperature of 300 degrees for a long time, the grease becomes dry. Since the calendering roller is always in a rotating state, the dry grease is rubbed into powder. The air flow fluctuations around the calendering roller will cause the oil residue powder to fall onto the glass plate, causing stone defects and other abnormalities, resulting in the falling of the glass plate, causing huge losses in production and increasing the labor intensity of personnel.
[0003] Patent No. 202211604967.1, published on August 20, 2024, discloses a calender roller cooling device for a calendering machine, which relates to the field of calender rollers for calendering machines. The invention comprises: a first vertical plate and a second vertical plate, wherein a plurality of calendering shafts are rotatably connected between the first vertical plate and the second vertical plate, and one end of the plurality of calendering shafts extends to the outside of the first vertical plate, and the two calendering shafts are connected by a transmission belt. The present invention, through the action of a rotating cleaning mechanism and a circulating water blowing mechanism, can, on the one hand, wipe off the residual glass liquid on the calendering roller to prevent the glass liquid from adhering to the outer wall of the calendering roller after cooling, thereby improving the flatness of the outer wall of the calendering roller and improving the use effect of the calendering roller on the "extrusion" molding of photovoltaic glass; on the other hand, it can circulate the cooling water inside the calendering shaft, thereby improving the fluidity of the cooling water inside the calendering shaft and reducing the temperature rise rate of the cooling water inside the calendering shaft, thereby improving the use effect of the cooling water used by the staff to cool the calendering roller.
[0004] As the specifications of photovoltaic glass in the current market are getting larger and larger, in order to meet the market demand for large-sized glass plates, the width of the overflow port is getting wider and wider, the original glass plate and the edge fire are getting closer and closer to the shaft neck, and the temperature at the shaft neck is getting higher and higher. Since the calendering roller is always in a rotating state, the dry grease is rubbed into powder. The air flow fluctuations around the calendering roller will cause the oil residue powder to fall onto the glass plate, causing stone defects and other abnormalities, resulting in the falling of the glass plate, causing huge losses in production and increasing the labor intensity of personnel.

[0018] The following is a further detailed description of the specific implementation methods of the present invention by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the utility model concept and technical solution of the present invention and to facilitate its implementation.
[0019] See also Figure 1-3 A calendering roller shaft neck oil-blocking and insulating water bag, the water bag 1 is attached to the outside of the calendering roller shaft 2, water flows in the water bag 1, and a connecting water tank 6 is provided in the water bag 1. The connecting water tank 6 is arranged along the inside of the water bag 1, and the two ends of the connecting water tank 6 are respectively connected to the water inlet pipe 4 and the water outlet pipe 5, and the water bag 1 is semicircular.
[0020] The water bag 1 is wrapped around the outside of the calendering roller 2, and water is passed through the water bag 1 to cool the water bag 1, thereby achieving the effect of cooling the calendering roller 2, and because the water bag 1 is in contact with the surface of the calendering roller 2, the cooling effect can be better achieved by increasing the heat exchange area; the cooling water is transported to the inside of the water bag 1 by the connecting water tank 6, so that the water bag 1 is heat exchanged through the connecting water tank 6 to complete the cooling of the water bag 1, and the calendering roller 2 is cooled by the water bag 1, and because the connecting water tank 6 is located inside the water bag 1, the cooling water can be avoided from overflowing, causing pollution to the equipment and the environment, and the cooling water can be recycled to avoid waste; the water inlet pipe 4 and the water outlet pipe 5 are used to complete the water inlet and outlet of the connecting water tank 6; so that the water bag 1 can be more in contact with the calendering roller 2, and the cooling and heat dissipation work can be better completed.
[0021] An extension rod 3 is provided at the end of the water bag 1, and a water inlet pipe 4 and a water outlet pipe 5 are provided at the end of the extension rod 3; water is exchanged through the water inlet pipe 4 and the water outlet pipe 5 to achieve the purpose of long-term and efficient cooling.
[0022] An oil retaining ring 7 is provided on the inner side of the water bag 1; the oil retaining ring 7 is used to block the overflowing grease to prevent leakage and coking.

The inlet section 61 is closer to the calendering roller 2, which can better carry out heat exchange. At the same time, the cooling water in the outlet section 62 has a relatively high temperature and is slightly farther away from the calendering roller 2, reducing the impact on heat exchange.
[0025] A heat-insulating pipe 11 is provided in the water outlet section 62 to reduce the influence of the high-temperature cooling water in the water outlet section 62 on the cooling side.
