Non-woven fabric 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. The non-woven fabric fiber cooling mechanism comprises a cooling barrel.A water inlet tank and a water outlet tank are fixedly installed on the cooling barrel, and water-sealed bearings are fixedly installed on the water inlet tank and the water outlet tank. A driving shaft is installed on the water inlet tank in a rotating mode, and a driven shaft is installed on the water outlet tank in a rotating mode. Heat absorption rollers are fixedly installed on the driving shaft and the driven shaft, and a water inlet groove is formed in the driving shaft. The water inlet groove communicates with a through hole, and a through groove is formed in the driven shaft. Hot-molten trickle can be subjected to primary fast cooling formation through the heat absorption rollers which are kept in a low-temperature state; meanwhile, a fan is adopted to produce wind power so thatsecondary cooling can be conducted, and the cooling process can be completed rapidly and efficiently; and cooling water can take away heat in the circulation process, the specific heat capacity of thecooling water is high relative to that of the air, heat absorption capacity is high, the influence by the air temperature from the outside is small and thus the cooling effect can be stably guaranteed.

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.

Problems solved by technology

[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
