Description

Technical Field

[0001] The utility model relates to the field of non-woven fabrics, in particular to a composite pre-pressing device for PET non-woven fabrics. Background Art

[0002] Non-woven fabric, also known as non-woven fabric, is a kind of cloth-like material produced by processing various fiber raw materials with needle-pressing machinery or carding machinery, and forming or bonding them with high pressure. One of the links in the production process of non-woven fabric is pre-pressing the non-woven fabric, which is very important in the non-woven fabric process.

[0003] At present, it is inconvenient to lift the pre-pressing mechanism of non-woven fabrics. When facing non-woven fabrics of different thicknesses, most of them adopt manual adjustment of the height of the pressing roller, which is rather troublesome. In addition, in the process of pre-pressing the non-woven fabrics, there is a lack of a device to clean the dust on the non-woven fabrics, resulting in poor cleanliness of the non-woven fabrics. At the same time, after the friction between the pre-pressing roller and the non-woven fabric, static electricity will be generated, causing dust and lint to be adsorbed on the pre-pressing roller, which has a great impact on the subsequent pre-pressing of the non-woven fabrics and greatly increases the workload of cleaning the pre-pressing roller in the later stage. Utility Model Content

[0004] The purpose of the utility model is to address the deficiencies in the prior art and provide a PET non-woven fabric composite pre-pressing device, which adjusts the distance between the pre-pressing rollers by an adjusting component, vacuums the non-woven fabric by a dust suction component, and simultaneously drives a cleaning component to clean the pre-pressing rollers while pre-pressing the fabric by the pre-pressing component. The distance between the pre-pressing rollers is conveniently adjusted to adapt to fabrics of different thicknesses, and the non-woven fabric and the pre-pressing rollers can be cleaned at the same time, saving time and effort.
