Description

Glass calender

Technical Field

The utility model relates to a glass makes technical field, especially relates to a glass calender.

Background

The main structure of the existing calender for producing glass is composed of two main rollers (an upper main roller 101 and a lower main roller 102), a pallet water bag 103 for receiving glass, or a conveying roller 104 (as shown in fig. 1) which drives the glass to move forward. The two main rollers are internally filled with water and have the function of quickly pressing the glass liquid with the temperature of more than 1000 ℃ into a plate with certain thickness and patterns. The temperature of the plate pressed by the two main rollers is rapidly reduced to 620-880 ℃. The water cooling in the two main rollers is very critical, on one hand, the glass liquid is cooled rapidly, and on the other hand, the thickness deviation of the plate can be strictly controlled. Because the surface temperature of the roller is very high due to the heat conduction influence of the high-temperature liquid material, if the water inside the roller is not well cooled, the phenomenon that the thickness of the whole sheet of plate is not uniform can occur. When the thickness deviation is serious, even the plate can not be normally picked and boxed because the thickness deviation of the plate can not meet the national standard or the industrial standard, so that the finished product rate is very low, and the production cost is greatly increased.

On the other hand, from the manufacturing process perspective, when the high-temperature liquid material is pressed and formed by a calender with a structure of two main rollers, the material temperature before the rollers is generally over 1200 ℃ due to the high material temperature, especially in the field of microcrystalline glass, and if the pattern (pattern density and depth) engraved on the surface of the upper main roller for calendering is not proper, the liquid material is rolled up by the rotating upper main roller for calendering, and even wraps the upper main roller for calendering, so that the damage of the glass calender equipment is caused. For this reason, the glass calender having the two main roll structure is greatly limited in producing desired products (types of patterns of products).
