Single-sided corrugated preheating device

The utility model relates to a single-sided corrugation preheating device, which belongs to the field of corrugated board production equipment, and comprises a bracket, a preheating cylinder rotationally connected with the bracket, and a heat preservation cover covering the preheating cylinder, and the heat preservation cover is fixedly connected with the bracket. The heat insulation cover is arranged, so that the heat loss can be reduced, more heat can be transferred to the raw material paper, the preheating effect is improved, and meanwhile, the purposes of reducing the loss and saving energy are achieved. In addition, the arrangement of the heat preservation cover can reduce heat diffusion to an external working environment, so that nearby workers can work comfortably, and the possibility of heatstroke of the workers is reduced. 本申请涉及一种单面瓦楞预热装置，属于瓦楞板生产设备的领域，包括支架、与支架转动连接的预热缸，还包括罩设在预热缸外部的保温罩，且保温罩与支架固定连接。保温罩的设置可降低热量的损耗，以使得更多的热量传递至原料纸处，提高预热效果，同时达到降低损耗节约能源的目的。此外，保温罩的设置可减少热量扩散至外界工作环境中，以便附近工作人员可较为舒适的工作，降低了工作人员中暑的
