Description

Technical Field

[0001] This utility model relates to the technical field of tempered glass production equipment, specifically to a smooth air return air grate roller conveyor. Background Technology

[0002] The function of the air grid section in a horizontal roller conveyor glass tempering unit is to cool the heated glass under a certain air pressure, thereby obtaining tempered or semi-tempered glass. To ensure glass quality, the glass must not only cool uniformly on the same side during cooling in the air grid section, but also have a uniform temperature across both the top and bottom surfaces. Centrifugal fans are commonly used for cooling the glass in the air grid section, and the cooling efficiency during the glass cooling process has a significant impact on the overall energy consumption of the equipment.

[0003] Currently, existing technologies for wind grating sections generally employ a steel roller conveyor structure wound with aramid rope, such as... Figure 1 As shown, glass 7 is conveyed via an existing roller conveyor 5. Lower nozzles 6 and upper nozzles 8 simultaneously cool the upper and lower surfaces of the glass. The existing roller conveyor 5 is a steel body with heat-resistant ropes wound around it. During the blowing process, due to the limited thickness of the outer heat-resistant ropes of the existing roller conveyor 5, the cooling air blown by the lower nozzles 6 onto the lower surface of the glass 7 cannot be effectively and promptly discharged, thus affecting the cooling efficiency of the lower surface of the glass 7. Simultaneously, when the air pressure is relatively high, the glass 7 moves unstablely within the air grid, even exhibiting a jumping phenomenon. To address this, existing technologies typically add air pressure plates 9 between the upper nozzles 8. These air pressure plates 9 correspond to the lower existing roller conveyor 5, making the cooling return air from the upper part of the glass nearly identical to that from the lower part. However, adding air pressure plates 7 further reduces the upper return air effect, further decreasing the cooling efficiency and significantly increasing the energy consumption of the equipment. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a smooth air return grate roller conveyor. By optimizing the structure of the transmission roller conveyor, the return air on the lower surface during glass cooling is effectively enhanced, thereby reducing the energy consumption of the equipment.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a smooth return air grate roller conveyor, including a roller core for bearing and driving the roller conveyor and a spiral steel belt, wherein the spiral steel belt is fixed on the roller core and a heat-resistant rope is wrapped on the spiral steel belt.

[0006] Preferably, the roller core is provided with a plurality of fixing blocks at intervals, and the spiral steel strip is spirally wound and fixed on the roller core through the fixing blocks.

[0007] Preferably, the connection between the fixing block and the roller core and the spiral steel strip is a welded connection.

[0008] Preferably, the length of the spiral steel belt from the roller core is the same as the length of the fixed block.

[0009] Preferably, the spiral steel belt is directly welded on the roller core.

[0010] Preferably, the roller core is a solid steel rod or a hollow steel tube.

[0011] Preferably, the temperature-resistant rope is made of aramid rope or ceramic glass fiber rope.

[0012] Preferably, the width of the temperature-resistant rope is the same as the width of the spiral steel belt, the pitch of the temperature-resistant rope is the same as the pitch of the spiral steel belt, and the temperature-resistant rope and the spiral steel belt are glued and bonded.

[0013] According to the above technical scheme, the beneficial effects of the utility model are:

[0014] 1. The utility model provides a wind grate roller way of smooth return air, adds spiral steel belt on main body roller core, winds temperature-resistant rope on spiral steel belt, and temperature-resistant rope directly contacts glass, reduces the influence of direct contact of steel parts on glass cooling, simultaneously, the rigidity and deflection of the roller way core and spiral steel sleeve ensure that the rigidity and deflection of the roller way meet use requirements.

[0015] 2. The utility model in the glass cooling process, cooling air can be discharged smoothly from the return air space formed between spiral steel belt and roller core, greatly enhances the cooling effect of the lower surface of glass. Since the lower cooling return air is smooth, the upper part can cancel the air pressure plate assembly, which reduces the equipment cost on the one hand, reduces the cooling energy loss on the other hand, and improves the energy utilization rate. In addition, the spiral steel belt has a mature processing technology, is easy to form and has low manufacturing cost, so the application has strong practicality. BRIEF DESCRIPTION OF DRAWINGS
