BACKGROUND OF THE INVENTION
In general, Nylon is a synthetic polymer polyamide, a synthetic fiber developed by DuPont in 1935, in an attempt to substitute synthetic plastic for a substitute for natural silk. In 1938, it was the world's first full- It was sold as synthetic fiber.
Such synthetic fibers, nylon, are used in various fields such as tire cords, automobile parts, and the like, which are manufactured from yarn of fabric, that is, yarn, for women's stockings, military parachutes, armor, fire extinguisher, underwear and socks.
On the other hand, nylon, which is a synthetic fiber, is spun by fibers made of nylon yarn, and nylon yarns such as fibers are produced during the production of fibers by nylon yarns. And is recycled.
Conventional mixed-paced reproduction apparatuses for reproducing various synthetic fiber materials such as nylon and polyester are disclosed in Patent Registration No. 10-0355004 (published on Oct. 10, 2002).
Such conventional reproducing apparatus of the mixed-pacer is for making fibers by mixing fibers of various kinds of synthetic fiber materials, polyester, nylon, acryl, etc., and recycling the remaining pa- per, so that the reproducing apparatus of the mixed- So that the molten liquid in the molten chamber 18 is discharged into the discharge port 16 by means of the rotary tool 17. In this case,
However, since the above-described conventional mixing-type regenerating apparatus merely mixes and melts the mixture to be discharged, it is difficult to reuse the original recycled material because it contains foreign substances.
Conventionally, there is a device for regenerating nylon filament. However, since there is a problem as described below, the nylon filament regenerated by a conventional apparatus is merely recycled as an engineering plastic, Has not been reused.
First, the conventional nylon-pacer reproducing apparatus has a problem in that the melting time of the nylon pacer is not constant since the uneven nylon pacer raw material mixed in a lump form or the like is manually introduced into the regenerating apparatus.
Second, in the conventional nylon-pacer reproducing apparatus, since the diameter of the extruding die for extruding the liquid nylon in which the nylon pascals are melted is large and the strand of extruded nylon is not constant because the extrusion pressure is not constant, There is a problem that the size is not uniform.
Third, the conventional nylon-pacer reproducing apparatus has a problem that nylon chips are not in good quality due to foreign substances mixed in the nylon pads.
Therefore, there is a demand for development of a recycling apparatus and a regeneration method of nylon pacer in order to solve the above problems and reuse the nylon papa as a raw material for the original nylon company.
Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made in order to solve the above problems, and it is an object of the present invention to provide a nylon filament yarn which is produced by cutting nylon filaments, It is an object of the present invention to provide a nylon pacifier reproducing apparatus which minimizes foreign matter in molten nylon and uniformizes the size of nylon chips so that the nylon chips can be reused as raw materials for producing original nylon yarns.
It is another object of the present invention to provide a method for regenerating nylon papa which can be reused as a raw material for producing original nylon yarn produced in the process of producing fibers by nylon yarn.
The present invention relates to a pulverizer for pulverizing nylon pulp to a predetermined size; A crushing feeder for uniformly feeding the pulverized powder to the extruder by means of a screw conveyor; An extruder which melts and extrudes the supplied pulverized powder by an electric heater; A pre-filter for primarily removing foreign matters from melt-extruded molten nylon; A gear pump for compensating an extruding pressure of the molten nylon melt extruded by the extruder and performing a volume feed to maintain a constant flow rate; A fine filter for secondarily removing foreign matter from molten nylon which is pressure-fed by the gear pump; An extrusion die for extruding molten nylon into a strand having a thickness of 2.5 mm; A strand cooling unit for water-cooling the nylon strand extruded from the extrusion die in a water tank; A strand drying unit for drying the nylon strand cooled in the strand cooling unit; A strand cutting unit for cutting a nylon strand dried by the strand drying unit into a predetermined length and processing the nylon strand into a nylon chip; And a controller for controlling the operation of the above-described configuration.
In the present invention, an extrusion pressure sensor is further provided between the extruder and the pre-filter to control the rotation speed of the motor of the extruder in accordance with the pressure of the molten nylon to be extruded.
In addition, the present invention provides a method for producing a nylon filament yarn, A pulverized powder supplying step of uniformly supplying pulverized powder to the extruder by means of a screw conveyor; A melt extrusion process in which the supplied pulverized powder is melted and extruded by an electric heater; A primary foreign matter removing process for removing foreign substances in the extruded molten nylon; A volumetric pumping process for volumetrically feeding the molten nylon by a gear pump to back up the discharge pressure; A second foreign matter removing process for removing foreign substances in the molten nylon to be volume pumped; A nylon strand extrusion process for extruding the extruded molten nylon into a strand having a thickness of 2.5 mm; A strand cooling process for submerging the nylon strand in a water tank; Strand drying process for drying nylon strands; And a strand cutting process for cutting the nylon strand into a predetermined length and processing the strand into a regenerated nylon chip.
In the present invention, the melt extrusion process further includes a pressure interlocking extrusion control process for controlling the rotation speed of the motor of the extruder in conjunction with the pressure of the molten nylon extruded from the extruder.
The present invention has the following effects by means of solving the above-mentioned problems.
First, according to the present invention, nylon paraffin raw material is pulverized into a predetermined size and shape by a pulverizer which cuts and pulverizes nylon pulp to a predetermined size, and the pulverized pulp is uniformly supplied to an extruder by a pulverizer feeder, which is a screw conveyor, There is an effect that the melting of the nylon layer can be performed uniformly and quickly.
Secondly, since the volume pumping is performed by the gear pump that compensates the extrusion pressure of the molten nylon melt-extruded in the extruder and performs volume-pushing so as to maintain a constant flow rate, extrusion in the extrusion die is constantly performed, A pre-filter is provided at the front end and a fine filter is provided at the rear end of the gear pump to remove foreign matter in a first and a second order, thereby minimizing the foreign matter content of the regenerated nylon chip.
Thirdly, the present invention has an extrusion die having a nozzle of 2.5 mm so that the thickness of the extruded nylon strand is reduced by extruding the molten nylon so that the size of the regenerated nylon chip becomes uniform, and the extruder and the pre- the pressure of the molten nylon extruded from the extruder controls the rotation speed of the motor of the extruder in accordance with the pressure of the molten nylon extruded by the extruder so that the flow rate of the molten nylon extruded from the extruder is kept constant, The nylon strand is uniformly maintained.
