AI Technical Summary
Existing fiber felt hot roller devices lack preheating equipment, resulting in uneven heating of materials, affecting product quality. Furthermore, traditional hot air preheating methods may cause the fiber felt to curl up and fail to enter the hot roller device smoothly.
A continuous hot rolling device for fiber felt was designed, comprising a preheating box, heating plates, lifting blocks, and a pressure roller system. The heating plates preheat the fiber felt, the lifting blocks adjust the coverage of the insulation cloth, and the pressure rollers adjust their height according to the thickness of the fiber felt to ensure that the fiber felt enters the hot rolling device flat.
This process achieves uniform preheating and leveling of the fiber felt, improves product quality, prevents heat loss, and ensures that the fiber felt is conveyed smoothly within the hot roller device.
