Efficient drying system for non-woven fabric

Abstract

The invention discloses an efficient drying system for non-woven fabric. The efficient drying system comprises a closed box body, a fabric inlet and a fabric outlet are formed in the top and the bottom of one side of the box body respectively, and an upper pressing roller and a lower pressing roller which are used for clamping the non-woven fabric are arranged at the positions, located at the fabric inlet and the fabric outlet, in the box body respectively; a plurality of steering rollers are sequentially arranged in the box body in a staggered mode from top to bottom, the two ends of each steering roller are rotationally installed in the box body, and an inner cavity is formed in each steering roller; the inner cavities of every two adjacent steering rollers are sequentially in sealed communication end to end through connecting pipes, and the connecting pipes are in sealed communication with the inner cavities of the steering rollers from the axes of the steering rollers; and air outlet holes communicating with the inner cavities of the steering rollers are uniformly formed in the surfaces of the steering rollers, and the end parts of the steering rollers at the bottom are in sealed communication with a hot drying fan. The efficient drying system has the advantages that hot dry air is directly conveyed to the surface of the non-woven fabric through the interiors of the steering rollers, and the drying efficiency is greatly improved.

Description

technical field [0001] The application relates to the processing of non-woven fabrics, in particular to a high-efficiency drying system for non-woven fabrics. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of directional or random fibers. They are a new generation of environmentally friendly materials. Low cost, recyclable and so on. For example, polypropylene (pp material) pellets are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. It is called cloth because of its appearance and certain properties. [0003] It is not interwoven and braided by one yarn, but the fibers are directly bonded together through physical methods, so when you get the sticky scale in your clothes, you will find that, It is impossible to pull out a single thread. Nonwovens have broken through the traditional textile principles, and have the charac...

Problems solved by technology

[0004] After the non-woven fabric is colored and cleaned, it needs to be dried. The existing drying device will have problems such as incomplete drying and poor efficiency.

[0005] Patent No. 201720953795.7 discloses a drying device for non-woven fabrics. The device can hardly pass through the non-woven fabrics. The hot dry air basically floats upward from both sides of the non-woven fabrics and then goes out. The drying efficiency is particularly high. Low
