Technical Field

The invention belongs to the technical field of melt-blown fabric manufacturing, and particularly relates to a special high-efficiency air-jet spinning system for melt-blown superfine fibers.

Background

The melt-blown superfine fiber is formed by extremely stretching a thermoplastic material under the blowing of high-temperature hot air, the average diameter of the melt-blown fiber is between 0.5 and 5 mu m, and a common melt-blown device directly spreads the superfine fiber after being sprayed to form melt-blown cloth, so that single fiber or fiber bundles cannot be collected, and the performance of the fiber bundles cannot be utilized. The superfine fiber bundle is composed of a plurality of superfine fibers, so the superfine fiber bundle has a very large specific surface area, is a filtering and heat-insulating material with excellent performance, and can make up for the problem of insufficient strength of single fibers.

Meltblown microfiber is produced by conveying a high polymer through a screw extruder to a meltblowing die and spraying it onto a receiving web to form a meltblown web. When the melt-blown die head is used for a long time, the high polymer melt remained in the melt-blown die head is easy to block a melt-blown pipeline after being dried and solidified, so that the non-uniformity of the injection quantity of the melt-blown die head can be caused, and the melt-blown quality is influenced; simultaneously at melt-blown in-process, the too high degree of adhesion between the fibre that leads to on the net curtain of melt-blown filament temperature of traction out easily makes fibrous structure become too fine and close, thereby can influence the air permeability of melt-blown cloth, and easy adhesion forms on the cylinder to remain, consequently need cool down the processing to the melt-blown fibre of injection, current cooling device only adopts the cold air duct to cool down the fibre of eruption, because melt-blown fibre jet velocity is too fast, the cold air duct cooling effect is limited, can not effectively cool down.

The working principle is as follows:

when the melt-blowing device works, the screw extruder extrudes the high polymer melt into a melt-blowing die head through a pipeline, and the high polymer melt is sprayed out through temperature spinneret orifices in a spinneret plate, and meanwhile, the high polymer in the spinneret orifices is heated and insulated by electric heating wires; the hot-blast main in the locating plate passes through first hot-blast main and second hot-blast main and from air current channel and crack groove blowout to draft the high polymer that erupts, cooling water spouts from the atomizer on the spray plate in cooling device's the cold water pipe, and the cold air of cooperation gas transmission board orifice spun simultaneously cools down to melt the blown fiber, carries out direct cooling to melt the blown fiber while, and the drop of water on the blown fiber evaporates the heat absorption under cold wind blows. When the melt-blown die head is cleaned, the air channel adjusting plate is adjusted in the movable groove, so that the air channel adjusting plate moves and closes the first hot air channel and the second hot air channel, the hot air pipe conveys hot air to the spinneret orifice through the cleaning pipeline and the movable groove, and high polymers remained in the spinneret orifice are heated and discharged from the spinneret orifice to achieve the effect of clearing.

The curtain net receiving device in the receiving device collects the melt-blown superfine fibers sprayed by the melt-blown die head, the bundling device bundles the superfine fibers and forms fiber bundle strips, and a guide strip roller is arranged below the bundling device and guides the fiber bundle strips to the air jet spinning device.

The fiber bundle strip in the air jet spinning device is drafted through the drafting roller, and when the fiber bundle strip passes through the inner cavity of the yarn spraying nozzle, twisting is obtained through vortex airflow in the inner cavity of the yarn spraying nozzle, so that the fiber bundle strip forms yarn, and the yarn is guided to the impurity removing device through the yarn guide roller.
