Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of paper product processing, in particular to a drying device for paper product processing. Background Art
[0002] Paper products refer to products made from paper and cardboard as raw materials and further processed. Paper products are cost-effective and have good elasticity and toughness. However, during use, the produced paper products are easily affected by the environment, causing the paper products to become damp and moldy. At this time, a dryer is needed to dehumidify and dry the paper products to remove moisture from them. The heat sources currently used by dryers include coal, electricity, gas, and microwaves. At present, microwave dryers are generally used to dry paper products. Microwave dryers use microwave radiation to dry the moisture in paper products from the inside to the outside, which can ensure that the paper products are dried evenly and the outside will not be dried while the inside is still wet.
[0003] For paper product dryers, box-type dryers are generally used. Paper products are transported from the inlet to the outlet of the dryer by a conveyor belt. The paper products are heated by microwave radiation or other heat sources in the box to heat the ambient air, and the temperature in the box reaches an appropriate level for dehumidification. The moisture in the material is continuously evaporated, reducing the humidity of the paper products and keeping the paper products dry.
[0004] During the drying process of paper products, the dried paper products are prone to stick to the surface of the conveyor belt, causing damage to the paper products. In addition, the dried paper products are prone to wrinkles after drying, affecting the subsequent use of the paper products. Utility Model Content
