Description

Technical Field

[0001] The invention relates to the field of non-woven fabrics, in particular to a non-woven fabric drying device. Background Art

[0002] Non-woven fabrics are made of directional or random fibers. They are usually made of polyester and polyester fibers, and are made through a needle punching process. They are moisture-proof, breathable, flexible, thin, flame-retardant, non-toxic and tasteless, and are inexpensive and recyclable.

[0003] Non-woven fabric drying equipment is an indispensable part of the non-woven fabric production process. It is mainly used to dry the produced non-woven fabric to remove moisture from it so that it has better physical properties and service life. The existing Chinese public patent document: CN116123848B discloses a non-woven fabric drying and shaping equipment. The non-woven fabric is conveyed by a drying conveyor roller, and the dry hot air passes through the vents on the drying roller to dry the non-woven fabric with hot air. The contact between the non-woven fabric and the drying conveyor roller can be effectively dried; the auxiliary drying device sprays hot air in the horizontal direction along the non-woven fabric from both ends to keep the non-woven fabric from expanding horizontally. The auxiliary drying device reduces the deformation of the non-woven fabric, increases the contact area between the hot air and the non-woven fabric, improves the drying effect, and shortens the drying time; the humidity of the air used to dry the non-woven fabric increases and is recovered by the air collecting hood to the air heating and dehumidification equipment after passing through the breathable membrane for heating and dehumidification treatment and then recycled to reduce heat loss. Although the non-woven fabric can be dried quickly, multiple drying conveyor rollers are located below the non-woven fabric, and the air evaporates from bottom to top. The bottom of the non-woven fabric has a relatively high temperature, which can easily cause uneven temperature between the top and bottom of the non-woven fabric. In addition, the non-woven fabric is laid flat on the drying conveyor roller, and there is a lack of stretching of the non-woven fabric, which can also cause wrinkles. Summary of the invention
