Description
Technical Field
The invention belongs to the technical field of synthetic fiber production equipment, and particularly relates to a blowing and cooling device for melt-spun filaments.
Background
The melt-spun filaments are also called melt-spun, and are formed by extruding a high polymer spinning melt such as PA or PE from a spinneret orifice of a spinneret plate of a spinning machine, cooling the extruded melt stream by blowing air, stretching, and finally solidifying into filaments, and the filaments are used as post-spun drawn filaments or other purposes. The air-blowing cooling device belongs to the category of a side-blowing cooling device.
As is known in the art, since the fine and dense melt filaments just extruded from the spinneret holes of the spinneret are in a high-temperature molten state because they are not yet solidified and formed and the melt temperature is much higher than the ambient air temperature, and since the melt filaments are very delicate, air cooling is performed by a cooling device, that is, air cooling is performed by an air-blowing cooling device to solidify the melt filaments from fluid fibers into solid fibers.
For melt-spun filaments, it is common to use a unidirectional side-blown cooling device for side-blown cooling, specifically, cooling air blown from one side (usually the rear side) of the spun fibers toward the fibers to be cooled. The unidirectional side-blowing cooling device has the advantages of simple structure and convenient operation, but because the inner side of one bundle of fibers is close to the cooling air, the cooling speed of the fibers close to the cooling air side is high, and the cooling speed of the fibers far away or back to the cooling air side is low, so that the cooling among a plurality of single fibers in one bundle of fibers is uneven, the quality of the fibers is influenced, for example, the deviation rate of indexes such as linear density, elongation, strength and the like of the fibers is high, and the dyeing effect is also influenced.
Perhaps one would think as such; the adoption of the circular blowing cooling device can ensure that the fibers can obtain uniform cooling effect which is consistent inside and outside, however, because each position of the filament is provided with a plurality of (generally 6 to 16) spinning assemblies, if each spinning assembly is provided with a corresponding circular blowing head, the spinning assembly is inconvenient to start and operate, and the filament bundle of other assemblies can be influenced by one broken filament; and because the melt spinning staple fibers usually adopt a single large and round spinneret plate, the circular blowing cooling device with small blowing area and limited height can meet the circular blowing cooling requirement of melt trickle of spinneret orifices on the single large and round spinneret plate, but the melt spinning filaments generally adopt a group of spinneret plates arranged in the linear direction, so the circular blowing cooling device with small blowing area and limited height cannot be applied. Since the circular air blowing cooling device can be seen in published chinese patent documents such as CN202925169U (circular air blowing cooling device), CN103820868A (a circular air blowing device for producing ultra-fine denier, high quality spinning), CN2793105Y (fully enclosed circular air blowing device for cooling melt spinning), CN203923476U (a circular air blowing cooling device) and CN202809026U (a new circular air blowing device), etc., the applicant is not repeated.
Technical information of the aforementioned side-blowing cooling devices, typically "side-blowing device for cooling melt-spun filaments" as recommended in CN2151158Y, is also found in the published chinese patent literature, and since the patent appears to be single-side blowing, there are technical problems mentioned above by the applicant.
