It includes at least more then one forming device, sizing device, drying device and cooling device which are successively mounted on the machine frame from front to rear. Said sizing device includes at least more than two sizing devices and box type drying box. Between the forming device and sizing device an embossing device and pre-presing hot roller unit can be added, and between drying device and cooling device a calendaring device is added. Besides, it also includes fluff pulp fluffer, fibrids opening, conveying and metering device and powder additive device.

Description

technical field [0001] The invention relates to the technical field of papermaking equipment, in particular to an air-laid dry-laid paper machine. Background technique [0002] The traditional papermaking technology uses water as the medium to disperse and transport fibers. It is dehydrated by a cylinder or fourdrinier to form a paper web, and the fibers are bonded by hydroxyl bonds. Therefore, the production process requires a large amount of water, causing serious damage to the water environment. pollution. With the continuous progress and development of society, economy, and culture, as well as the increasing awareness of environmental protection, the pollution of the paper industry has become a serious social problem. However, the demand for paper and its products is increasing, and the contradiction is very prominent. [0003] Since the 1970s, non-woven fabric production technologies represented by carding, airflow, and spunbonding have been widely used. Among them, t...
