A non-woven fiber cooling mechanism

Abstract

The invention relates to the technical field of non-woven fabrics, in particular to a non-woven fabric fiber cooling mechanism, comprising a cooling cylinder, a water inlet tank and a water outlet tank are fixedly installed on the cooling cylinder, and a water inlet tank and a water outlet tank are fixedly installed on the cooling cylinder. Waterproof bearings, a driving shaft is rotatably installed on the water inlet tank, and a driven shaft is rotatably installed on the water outlet tank, heat-absorbing rollers are fixedly installed on the driving shaft and driven shaft, and a water inlet tank is arranged on the driving shaft , the water inlet tank is connected with a through hole, and the driven shaft is provided with a through groove; the first step of rapid cooling and shaping of the hot-melt fine flow is performed by the heat-absorbing roller kept at a low temperature, and the second step is performed by the wind generated by the fan. Cooling, complete the cooling process quickly and efficiently. The cooling water can take away the heat during the circulation process. The cooling water has a larger specific heat capacity than the air, has a strong heat absorption capacity, and is less affected by the external temperature, so it can ensure stable cooling. Effect.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to a non-woven fabric fiber cooling mechanism. Background technique [0002] Non-woven fabric refers to an ordered or disordered fiber non-woven sheet obtained by arranging or spraying the fibers formed by spinning onto the substrate and curing them in different forms. Therefore, non-woven fabrics have low cost, The advantages of wide range of uses, the forming process of non-woven fabrics mainly include spunbond method, melt blown method and composite method, and no matter which method is used, it starts with the preparation of fibers. After the textile raw material is heated into a melt, it is extruded or sprayed out from the machine, and then cooled to make a fiber. [0003] The current fiber cooling process mostly adopts the direct air-cooling cooling method, blowing the cold wind onto the melt stream for cooling and molding. This cooling method is too simple.

[0003] The current fiber cooling process mostly adopts the direct air-cooling cooling method, blowing the cold wind onto the melt stream for cooling and molding. This cooling method is too simple. Since the heat is completely dissipated by air circulation, it is easily affected by the external temperature environment. At the same time, the cooling time for one round is short and the cooling effect is poor. In view of this, we propose a non-woven fiber cooling mechanism
