Detailed Description
Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. It should be noted that in the description of the present invention, the terms "front", "back", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate directions or positional relationships based on those shown in the drawings, which are merely for convenience of description, but do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
The utility model provides a glass tempering furnace air return prevention compression roller, sets up respectively in the top of the conveying roller 9 that is close to glass tempering furnace grid inlet and grid outlet for prevent that stove interior hot-blast spills over, outside cold wind gets into. In this embodiment, only one side of the gate outlet of the glass tempering furnace is taken as an example, and the same principle is applied to one side of the gate inlet.
As shown in fig. 1, the press roll comprises a steel roll body 1, a roll sleeve 2 is tightly sleeved on the roll surface of the roll body 1, and the roll sleeve 2 is made of aramid fiber. Aramid fiber is a novel high-tech synthetic material, has excellent performances such as ultrahigh strength, high modulus and high temperature resistance, acid and alkali resistance, light weight and the like, the strength of the aramid fiber is 5-6 times that of steel wires, the modulus of the aramid fiber is 2-3 times that of steel wires or glass fibers, the toughness of the aramid fiber is 2 times that of the steel wires, the weight of the aramid fiber is only about 1/5 times that of the steel wires, and the aramid fiber is not decomposed or melted at the temperature of 560 ℃. Therefore, the roller sleeve 2 made of aramid fiber meets the requirements of glass toughening production, can avoid damaging the surface of glass, and can prevent the glass from being burst due to local quenching.
Specifically, the roller sleeve 2 is formed by weaving aramid fibers, is tightly sleeved on the roller surface of the roller body 1, and the wall thickness of the roller sleeve 2 is 8 mm. In order to prevent the roller sleeve 2 from slipping on the roller surface, the shaft heads at the two ends of the roller body 1 are provided with the anchor ears 3, the two ends of the roller sleeve 2 are hooped on the shaft heads by the anchor ears 3, and the roller sleeve 2 is braced on the roller surface of the roller body 1 through tension. In addition, the roller shell 2 can also be formed by winding aramid cloth, and the cloth head is integrated with the rest parts by sewing.
As shown in fig. 2, the pressing roller is connected to one end of the lever 6, the other end of the lever 6 is connected to the counterweight 8, and the lever 6 is rotatably connected to the fixed lever rotating shaft 7. The moment of the compression roller end is slightly larger than that of the counterweight block 8 end, so that the compression roller is pressed on the corresponding conveying roller 9. In order to enable the moment at the end of the balancing weight 8 to be adjustable, the balancing weight 8 is connected with the lever 6 through threads, and the moment at the end of the balancing weight 8 is adjusted by adjusting the moment arm from the balancing weight 8 to the lever rotating shaft 7.
At ordinary times, the compression roller is pressed on the conveying roller 9, and the compression roller and the conveying roller 9 can block most of cooling air from entering the grid outlet 4. When the glass 5 comes out of the grid outlet 4 of the glass 5 toughening furnace, the glass 5 touches the press roller, and the touch force is enough to lift the press roller because the moment of the end of the press roller is slightly larger than that of the end of the balancing weight 8. After the glass 5 enters, the press roll lightly presses the glass 5, and the press roll and the conveying roll 9 block the cooling air again.
The conveying roller 9 is also a steel roller, and in order to prevent damage to the glass 5 caused by the roller surface of the conveying roller 9, particularly, in the conveying roller 9 on the side of the grid outlet 4, the glass 5 is cracked by the contact of the cold conveying roller 9 with the hot glass 5, and therefore, a fire rope is wound around the roller surface of the conveying roller 9. Due to the existence of the fire-resistant rope, a gap exists between the roller surface and the glass 5, so that when the glass 5 enters and exits the glass 5 toughening furnace, hot air in the furnace overflows from the gap, and the electric energy consumption of the glass 5 toughening furnace is undoubtedly increased. Therefore, the conveying roller 9 is also of the same structure as the compression roller, the roller sleeve 2 is also tightly sleeved on the roller surface of the conveying roller 9, and the material of the roller sleeve 2 is also aramid fiber. Thus, the cooling air below the glass 5 can be further reduced from entering the grid outlet 4, and the heat loss in the furnace can be reduced.
The part of the utility model not detailed is prior art. Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
