[0002] Spandex is the abbreviation of polyurethane fiber, which is an elastic fiber. Spandex is generally composed of multiple filaments. The full name of spandex fiber is spandex fiber, which is the abbreviation of polyurethane fiber. It is polymerized by PTMEG and MDI. It is a modern clothing industrial material. Recycled spandex is recycled spandex waste yarn on the market and reprocessed. For this purpose, a corresponding system is needed to convert spandex waste yarn into recycled spandex fiber.

[0003] In the existing regeneration process of spandex waste, it needs to be low-temperature crushed. Before crushing, the low-temperature treated spandex waste needs to be scattered. After crushing the spandex waste, most devices are unable to remove the fibers attached to the surface of their blades, increasing the subsequent cleaning burden, and are unable to effectively grind the blade surface, affecting the subsequent breaking up operation, and are unable to collect the debris generated by grinding. In addition, before using liquid nitrogen low-temperature treatment, the low-temperature storage end is not pre-cooled, which can easily cause large deformation of the device.

[0016] The present invention also discloses a method for preparing high-stability regenerated spandex fiber based on spandex waste yarn, which specifically comprises the following steps:

[0017] Step 1: During use, the user starts the first motor, the air compressor, and the second motor. The first motor drives the stirring rod and the conveying column to rotate. The air compressor draws in and compresses the outside air. Then the air compressor injects the compressed air into the vortex tube through the first three-way valve. The vortex tube converts the compressed air into cold air and hot air through vortex conversion. The cold air is introduced into the interlayer in the cooling shell through the cold air pipe to pre-cool the cooling shell. Finally, the cold air is discharged from the release pipe at the side end of the cooling shell. The second motor drives the gear assembly to operate through the first bevel gear assembly and rotates the cutting roller assembly. The gear assembly drives the first crushing knife to rotate. The other end of the cutting roller assembly drives the second bevel gear assembly to operate. The lower end of the second bevel gear assembly drives the second crushing knife to rotate, and the spandex waste silk is introduced into the cooling shell through the slot at the upper end of the cooling shell. The stirring in the cooling shell The mixing rod and the conveying column stir the spandex waste, and a proper amount of liquid nitrogen is sprayed from the nozzle at the upper end of the cooling shell into the cooling shell to accelerate the cooling and solidification of the spandex waste. After cooling, the liquid nitrogen vaporizes. After the spandex waste is completely cooled, the first cylinder is started, and the first cylinder drives the baffle to open. The solidified spandex waste gradually moves downward under the action of the rotating conveying column. When the spandex waste passes through the cutting roller assembly, the rotating cutting roller assembly breaks up the solidified spandex waste. Finally, the spandex waste is crushed by the blade when passing between the first crushing knife and the second crushing knife. The crushed spandex waste falls into the degreasing system. The degreasing system washes and degreases the spandex waste, and then transports it to the drying and dissolving system. After the drying and dissolving system dries the spandex waste mixture, it performs dissolution, degassing and other operations, and finally transports the formed spandex fiber to the recovery system.

[0018] Step 2: In step 1, after the precooling of the cooling shell is completed, the first three-way valve is reversed, and the first three-way valve injects compressed air into the jet plate through the conduit and the second three-way valve. The jet plate sprays compressed gas to blow the first crushing knife and the second crushing knife to promote the fall of the spandex fiber attached to the surface of the first crushing knife and the second crushing knife. After step 1 is completed, the first cylinder drives the baffle to reset, and the second cylinder is started. The second cylinder drives its extended end to reciprocate in the horizontal direction. The second cylinder drives the blade to reciprocate through the traction rod. When the blade passes through the rotating plate, the cleaning sponge on the inner side of the rotating plate cleans the impurities attached to the surface of the blade to promote the fall of impurities on the surface of the blade. When the blade end of the blade enters the cylinder, the rotating plate is reset under the action of the torsion spring to cover the blade. At this time, the third cylinder is started, and the third cylinder drives the brake pad to press the positioning column, and then fixes the grinding roller. The grinding roller is tightly fitted with the surface of the blade under the action of the sliding rod and the spring, and the blade end is polished to make the blade surface sharp;

[0019] Step three: In step two, when the blade surface has not entered the first crushing knife and the third cylinder has not been started, the grinding roller rotates under the action of the friction force of the blade. After the first three-way valve is reversed, the second three-way valve is reversed at a fixed time. The second three-way valve introduces compressed air into the connecting shell through the delivery pipe, and the connecting shell introduces compressed air into the connecting plate through the filter. The iron filings generated by grinding in the connecting plate are blown to the other end, and the magnet sheet absorbs the iron filings. At the same time, when the compressed air passes through the anti-blocking part, the impeller rotates under the action of the compressed air, and the impeller drives the cleaning brush to rotate under the action of the connecting shaft, and the bristle end of the cleaning brush cleans the impurities attached to the surface of the filter.

[0020] Preferably, in step one, the hot air generated by the vortex conversion in the vortex tube is introduced into the drying and dissolving system through the hot air pipe to accelerate the drying of the mixture, and the bristles of the shedding brush at the end of the rotating stirring rod clean the spandex waste threads attached to the inner wall of the cooling shell, thereby promoting the shedding of the spandex waste threads.

[0023] (1) The high-stability regenerated spandex fiber system based on spandex waste yarn is characterized by arranging a second cylinder in the cutting roller assembly, starting the second cylinder, and driving its extended end to reciprocate in the horizontal direction. The second cylinder drives the blade to reciprocate and retract through the traction rod. When the blade passes through the rotating plate, the cleaning sponge on the inner side of the rotating plate cleans the impurities attached to the surface of the blade, promoting the removal of impurities on the surface of the blade. When the blade end of the blade enters the cylinder, the rotating plate is reset under the action of the torsion spring to cover the blade to prevent the blade from being attached with impurities and affecting subsequent cutting.

[0024] (2) The high-stability regenerated spandex fiber system based on spandex waste yarn is achieved by arranging a grinding part in the cutting roller assembly, starting the third cylinder, and driving the brake pad to press the positioning column, thereby fixing the grinding roller. The grinding roller is tightly fitted to the surface of the blade under the action of the sliding rod and the spring, and the blade end is ground to make the blade surface sharp.

[0025] (3) The high-stability regenerated spandex fiber system based on spandex waste yarn is characterized by arranging a magnet sheet in the cylinder. After the first three-way valve is switched, the second three-way valve is switched at a fixed time. The second three-way valve introduces compressed air into the connecting shell through the delivery pipe, and the connecting shell introduces compressed air into the connecting plate through the filter screen. The iron filings generated by grinding in the connecting plate are blown to the other end, and the magnet sheet absorbs the iron filings.

[0026] (4) The high-stability regenerated spandex fiber system based on spandex waste yarn is characterized by arranging an interlayer in the device, and the vortex tube converts compressed air into cold air and hot air through vortex conversion, wherein the cold air is introduced into the interlayer in the cooling shell through the cold air pipe to pre-cool the cooling shell, thereby avoiding large deformation of the cooling shell caused by direct addition of liquid nitrogen.

The degreasing system 18 washes and degreases the spandex waste, and then transports it to the drying and dissolving system 19. After the drying and dissolving system 19 dries the spandex waste mixture, it performs dissolution, degassing and other operations to finally transport the formed spandex fiber to the recovery system 20.

[0048] Step 2: In step 1, after the precooling of the cooling shell 2 is completed, the first three-way valve 9 is reversed, and the first three-way valve 9 injects compressed air into the jet plate 13 through the conduit 10 and the second three-way valve 11. The jet plate 13 sprays compressed gas to blow the first crushing knife 173 and the second crushing knife 176, so as to promote the fall of the spandex fibers attached to the surfaces of the first crushing knife 173 and the second crushing knife 176. After step 1 is completed, the first cylinder 3 drives the baffle 4 to reset, and the second cylinder 1742 is started. The second cylinder 1742 drives its extended end to reciprocate in the horizontal direction. The second cylinder 1742 drives the blade 1747 to reciprocate through the traction rod 1746. When the blade 174 When passing through the rotating plate, the cleaning sponge on the inner side of the rotating plate cleans the impurities attached to the surface of the blade 1747, promoting the impurities on the surface of the blade 1747 to fall off. When the blade end of the blade 1747 enters the cylinder 1744, the rotating plate is reset under the action of the torsion spring to cover the blade 1747. At this time, the third cylinder 17487 is started, and the third cylinder 17487 drives the brake pad 17488 to press the positioning column 17486, thereby fixing the grinding roller 17485. The grinding roller 17485 is closely attached to the surface of the blade 1747 under the action of the sliding rod 17482 and the spring 17483, and grinds the blade end, so that the blade 1747 becomes sharp.

[0049] Step three: in step two, when the blade 1747 has not entered the first crushing blade 173 and the third cylinder 17487 has not been started, the grinding roller 17485 rotates under the action of the friction force of the blade 1747. After the first three-way valve 9 is reversed, the second three-way valve 11 is reversed at a fixed time. The second three-way valve 11 introduces compressed air into the connecting shell 177 through the delivery pipe 14. The connecting shell 177 introduces compressed air into the connecting plate 1743 through the filter screen, and the iron filings generated by grinding in the connecting plate 1743 are blown to the other end. The magnet sheet 1745 absorbs the iron filings. At the same time, when the compressed air passes through the anti-blocking member 1749, the impeller 17491 rotates under the action of the compressed air. The impeller 17491 drives the cleaning brush 17493 to rotate under the action of the connecting shaft 17492, and the bristle end of the cleaning brush 17493 cleans the impurities attached to the surface of the filter screen.

[0050] At the same time, the contents not described in detail in this specification belong to the existing technology known to those skilled in the art. In step one, the hot air generated by the vortex conversion of the vortex tube 15 is introduced into the drying and dissolving system 19 through the hot air pipe to accelerate the drying of the mixture. The bristles of the shedding brush at the end of the rotating stirring rod 6 clean the spandex waste yarns attached to the inner wall of the cooling shell 2, thereby promoting the shedding of the spandex waste yarns.
