Description

Technical Field

[0001] This application relates to the field of nylon production equipment technology, and in particular to a special-shaped, moisture-absorbing, quick-drying, multi-functional fine denier nylon filament production equipment and method. Background Technology

[0002] Nylon is a synthetic fiber primarily made of polyamide polymers, first invented by DuPont in the 1930s. Its molecular structure contains repeating amide groups, giving it high strength, lightweight, good elasticity, and wrinkle resistance. Nylon's abrasion resistance makes it widely used in sportswear, outdoor gear, car seats, and industrial products. Its UV resistance and chemical resistance make it suitable for various environments, especially excelling in outdoor use. Furthermore, nylon's quick-drying properties and low moisture absorption keep it comfortable in humid environments, but it may deform at high temperatures, requiring care during washing and ironing. In summary, nylon, due to its unique physical and chemical properties, has become an important and versatile material in the modern textile industry.

[0003] Chinese patent discloses a spinneret inspection equipment and method (authorization announcement number CN105547182A), which makes it less likely to miss micro-holes in the spinneret.

[0004] However, in the aforementioned patent, the spinneret needs to be disassembled for inspection. In actual production, when the sensor detects a blockage and issues an alarm, the staff often cannot determine whether the blockage is caused by the spinneret or other components (such as the raw material discharge pipe). Therefore, the staff can only eliminate the possibility of blockage by first disassembling the spinneret for inspection and then repairing it through elimination. However, this method can only be carried out by shutting down production and turning off the power, which seriously affects work efficiency. Therefore, the applicant proposes a special-shaped moisture-absorbing and quick-drying multifunctional fine denier nylon filament production equipment and method. Summary of the Invention

[0005] To quickly determine whether the spinneret is clogged and improve maintenance efficiency, this application provides a special-shaped moisture-absorbing and quick-drying multifunctional fine denier nylon filament production equipment and method.

[0006] The technical solution provided in this application for a non-standard moisture-absorbing and quick-drying multifunctional fine denier nylon filament production equipment and method adopts the following:

[0007] A special-shaped moisture-absorbing and quick-drying multifunctional fine denier nylon filament production equipment and method includes a raw material extrusion assembly, which includes a fixed box. A pump housing is fixedly connected inside the fixed box. Two meshing gears are rotatably connected inside the pump housing. A detection assembly is fixedly connected between one of the gears and the fixed box. A transmission assembly for transmission and a replacement assembly for replacement are provided at the lower end of the raw material extrusion assembly. A power-off assembly is fixedly connected to the side wall of the fixed box.

[0008] The detection assembly includes a fixed cylinder fixedly connected to a gear, a rotating shaft rotatably connected to the end of the fixed cylinder away from the gear, and the rotating shaft rotatably connected to the inner wall of the fixed box. A torsion spring is fixedly connected between the rotating shaft and the fixed cylinder. A magnet is fixedly connected to the lower wall of the rotating shaft. A cylinder is fixedly connected to the lower wall of the fixed cylinder. A magnetic plug that is magnetically attracted to the magnet is slidably connected inside the cylinder. A tension spring is fixedly connected between the magnetic plug and the lower inner wall of the cylinder. A push rod that passes through the lower end of the cylinder is fixedly connected to the lower wall of the magnetic plug. An outer cylinder is rotatably connected between the pump housing and the inner wall of the fixed box.

[0009] By adopting the above technical solution, when blockage occurs inside the spinneret assembly or pipe, the torsion spring of the fixed cylinder is deformed due to the increased rotational torque, causing the rotating shaft and the fixed cylinder to begin to misalign. This causes the magnetic plug to shift under the magnetic attraction of the lost magnet, ultimately enabling the fixed cylinder to drive the outer cylinder to rotate through the push rod.

[0010] Preferably, the raw material extrusion assembly also includes a motor fixedly connected to the right side wall of the fixed box, a suction pipe fixedly connected to the upper side wall of the pump casing, a raw material heating box fixedly connected to the upper side wall of the fixed box, and the suction pipe connected to the raw material heating box, a drain pipe rotatably connected to the lower side wall of the pump casing, a leak-proof plate provided on the lower side of the fixed box, two support frames fixedly connected between the fixed box and the leak-proof plate, and an air duct fixedly connected to the lower side wall of the leak-proof plate.

[0011] By adopting the above technical solution, the motor is started, which drives two gears to rotate in opposite directions, generating suction at the straw to draw in the raw material, and then discharges the raw material through the pipe.

[0012] Preferably, the transmission assembly includes a first bevel gear fixedly connected to the pipe, a rotating rod rotatably connected to the side wall of the fixed box, a pulley fixedly connected to one end of the rotating rod inside the fixed box, a guide rod fixedly connected to the side wall of the pulley, a second bevel gear meshing with the first bevel gear rotatably connected to the guide rod through a one-way bearing, and a belt sleeved between the pulley and the outer cylinder.

[0013] By adopting the above technical solution, after the outer cylinder rotates, the belt drives the pulley to rotate, and then drives the pipe to rotate through the second bevel gear and the first bevel gear.

[0014] Preferably, the replacement component includes a valve housing fixedly connected to the pipe, with delivery pipes connected to both the front and rear side walls of the valve housing, a spinneret fixedly connected to the end of the delivery pipe away from the valve housing, a valve core rotatably connected inside the valve housing, a T-shaped cavity being cut inside the valve core, and a pressure relief component fixedly connected to the lower side wall of the valve core.

[0015] By adopting the above technical solution, the rotation of the pipe will drive the valve shell to rotate, and the valve shell and the delivery pipe will drive the two spinneret assemblies to rotate, thereby replacing the two spinneret assemblies.

[0016] Preferably, the power-off assembly includes a switch cylinder fixedly connected to the side wall of the fixed box, a rotating rod inserted into the inside of the switch cylinder, a circular plate fixedly connected inside the switch cylinder, a square rod inserted into the circular plate, a return spring fixedly connected between the square rod and the pulley, a threaded groove carved into the inner side wall of the rotating rod, a short rod located inside the threaded groove fixedly connected to the side wall of the square rod, a switch button electrically connected to the motor fixedly connected to the inner side wall of the end of the switch cylinder away from the fixed box, and a spherical airbag fixedly connected to the end of the square rod near the switch button.

[0017] By adopting the above technical solution, when the source of the blockage is not the spinneret, the torque of the fixed tube rotation is still relatively large. Therefore, the outer tube will still drive the pulley and rotating rod to rotate through the belt, causing the rotating rod to drive the short rod and square rod to move through the threaded groove until the spherical airbag presses the switch button and turns off the power to the motor.

[0018] Preferably, the spinneret assembly includes a pressure box fixedly connected to the lower end of the delivery pipe, a spinneret plate fixedly connected to the lower end of the pressure box, and multiple evenly distributed spinneret holes drilled on the spinneret plate.

[0019] By adopting the above technical solution, the conveying raw material can be squeezed into a cross shape, which increases the gap between nylon monofilaments and improves the moisture absorption and quick-drying performance of nylon monofilaments.

[0020] Preferably, the pressure relief assembly includes a pressure relief pipe fixedly connected to the lower side wall of the valve core, the lower end of the pressure relief pipe is connected to a thick pipe, the thick pipe is fixedly connected to the anti-leakage disc through multiple support rods, a spring plate is fixedly connected inside the thick pipe, a sealing plate is fixedly connected to the upper side wall of the spring plate, and a thrust spring is fixedly connected between the sealing plate and the spring plate.

[0021] By adopting the above technical solution, the pressure relief component can play a pressure relief role when the spinneret is rotating, preventing excessive pressure inside the pump casing from damaging the gears.

[0022] A method for producing irregularly shaped, moisture-wicking, quick-drying, multifunctional fine denier nylon filament includes the following steps:

[0023] S1. Add raw materials into the raw material heating box and heat the raw materials into a liquid state, i.e., a gel state, through the raw material heating box. Then, the staff starts the motor and injects the liquid into the spinneret assembly.

[0024] S2. Under pressure, the liquid raw material is squeezed into multiple cross-shaped nascent fibers through multiple spinneret holes inside the spinneret assembly, and gradually solidifies and solidifies as the temperature decreases.

[0025] S3. After the staff observes the two spinnerets being rotated and replaced, the replaced spinnerets are tested by the testing equipment and then cleaned by the cleaning equipment. After cleaning, the spinnerets are then installed.

[0026] S4. Multiple nascent fibers are rotated and wound together using a synthesis device to synthesize a single nylon monofilament. The nylon monofilament is then packaged into rolls and subsequently dyed and used to produce fabrics.

[0027] In summary, this application includes at least two of the following beneficial technical effects:

[0028] 1. By utilizing the pressure changes in the spinneret assembly and tubing when blockage occurs, the torque of the gear rotation is altered. This allows for the replacement of the two spinneret assemblies via a transmission assembly and a replacement assembly, effectively shortening the maintenance time for the spinneret assembly.

[0029] 2. The square rod is moved by the rotation angle of the pulley. When the rotation angle of the pulley is too large, it means that the current blockage is not caused by the spinneret assembly. At this time, the motor is turned off by pressing the switch button on the square rod, which makes it easier for staff to come for further inspection.

[0030] 3. By adjusting the shape of the spinneret holes, the gaps between nylon monofilaments can be increased, thereby improving their moisture absorption and quick-drying properties. Attached Figure Description

[0046] The following is in conjunction with the appendix Figure 1 —8 provides further details regarding this application.

[0047] This application discloses a special-shaped, moisture-wicking, quick-drying, multifunctional fine denier nylon filament production equipment and method.

[0048] Example 1

[0049] Reference Figure 1-2A special-shaped moisture-absorbing and quick-drying multifunctional fine denier nylon filament production equipment and method includes a raw material extrusion assembly 1. The raw material extrusion assembly 1 includes a fixed box 101. A pump housing 102 is fixedly connected between the inner walls of the front and rear sides of the fixed box 101. Two meshing gears 103 are rotatably connected between the inner walls of the left and right sides of the pump housing 102. One end of one of the gears 103 is fixedly connected to the inner wall of the right side of the fixed box 101 and a detection assembly 2 for driving the outer cylinder 209 to rotate. A transmission assembly 3 for transmission and a replacement assembly 5 for replacing the spinneret assembly 6 are provided at the lower end of the raw material extrusion assembly 1. A power-off assembly 4 for powering off the motor 104 is fixedly connected to the side wall of the fixed box 101.

[0050] Raw materials are added inside the raw material heating box 105 and heated to a liquid state (gel state) by the raw material heating box 105. Then, the operator starts the motor 104. The motor 104 drives the fixed cylinder 201 to rotate through the rotating shaft 202 and the torsion spring 203. At this time, the rotational torque of the gear 103 is not large, and the torsion spring 203 will not deform. The fixed cylinder 201 drives one of the gears 103 to rotate. Under the meshing action, the two gears 103 rotate relative to each other and generate suction above, similar to the principle of a gear pump.

[0051] Reference Figure 3-4 The detection component 2 includes a fixed cylinder 201 fixedly connected to one end of one of the gears 103. A cylindrical cavity is formed at the end of the fixed cylinder 201 away from the gear 103. A rotating shaft 202 is rotatably connected to one end of the cylindrical cavity in the gear 103 via a bearing. The rotating shaft 202 is rotatably connected to the inner wall of the fixed housing 101. The output end of the motor 104 is fixedly connected to the rotating shaft 202. A torsion spring 203 is fixedly connected between the end of the rotating shaft 202 located inside the fixed cylinder 201 and the inner wall of the fixed cylinder 201. A magnet 204 is fixedly connected to the lower wall of the rotating shaft 202. A cylinder 205 is fixedly connected to the lower wall of the fixed cylinder 201. A sliding connection is made inside the cylinder 205. The magnetic plug 206, which is magnetically attracted to the magnet 204, is initially in contact with the side wall of the fixed cylinder 201 under the magnetic force of the magnet 204. The tension spring 207 is in a stretched state. The tension spring 207 is fixedly connected between the magnetic plug 206 and the lower inner wall of the cylinder 205. A push rod 208, which passes through the lower end of the cylinder 205, is fixedly connected to the lower side wall of the magnetic plug 206. An outer cylinder 209 is rotatably connected between the pump housing 102 and the inner side wall of the fixed box 101. The end of the push rod 208 away from the magnetic plug 206 and the inner side wall of the outer cylinder 209 are both roughened to increase the friction between the push rod 208 and the outer cylinder 209.

[0052] When the spinneret assembly 6 or the pipe 107 is blocked, the raw material inside the pump housing 102 cannot be discharged in time, making it difficult for the gear 103 to rotate. This leads to an increase in the rotational torque of the fixed cylinder 201. When the rotating shaft 202 drives the fixed cylinder 201 to rotate through the torsion spring 203, the torsion spring 203 will deform. At this time, the rotating shaft 202 and the fixed cylinder 201 will start to misalign. This causes the magnetic plug 206 to be displaced under the elastic force of the tension spring 207 after losing the magnetic attraction of the magnet block 204, and to contact the inner wall of the outer cylinder 209. Finally, when the fixed cylinder 201 rotates, it can drive the outer cylinder 209 to rotate through the push rod 208.

[0053] Reference Figure 2-3 The raw material extrusion assembly 1 also includes a motor 104 fixedly connected to the right side wall of the fixed box 101. A suction pipe 106 is fixedly connected to the upper side wall of the pump housing 102. A raw material heating box 105 is fixedly connected to the upper side wall of the fixed box 101, and the pump housing 102 is connected to the raw material heating box 105 through the suction pipe 106. A drain pipe 107 is rotatably connected to the lower side wall of the pump housing 102 through a mechanical seal. Since the mechanical seal is installed in a conventional and existing manner, its installation method will not be described in detail. A leak-proof plate 108 is provided on the lower side of the fixed box 101. Two support frames 109 are fixedly connected between the side wall of the fixed box 101 and the leak-proof plate 108. An air duct 110 is fixedly connected to the lower side wall of the leak-proof plate 108.

[0054] The raw material is absorbed inside the heating box 105 and discharged from the drain pipe 107. The raw material is then discharged through the T-shaped cavity 504 to the conveying pipe 502. Finally, when injected into the pressure box 601, the raw material is squeezed into nascent fibers through multiple spinneret holes 603 inside the spinneret assembly 6 under pressure.

[0055] Reference Figure 5 The transmission assembly 3 includes a first bevel gear 301 sleeved and fixed on the middle part of the pipe 107. A rotating rod 302 is rotatably connected to the side wall of the fixed box 101. A pulley 303 is fixedly connected to one end of the rotating rod 302 located inside the fixed box 101. A guide rod 305 is fixedly connected to the side wall of the pulley 303. A second bevel gear 307 that meshes with the first bevel gear 301 is rotatably connected to the guide rod 305 through a one-way bearing 306. The pulley 303 can only drive the second bevel gear 307 to rotate through the guide rod 305 when rotating in one direction. A belt 304 is sleeved between the pulley 303 and the outer cylinder 209.

[0056] When the outer cylinder 209 rotates, the belt 304 drives the pulley 303 to rotate, which in turn drives the pipe 107 to rotate through the second bevel gear 307 and the first bevel gear 301.

[0057] Reference Figure 7The replacement component 5 includes a valve housing 501 fixedly connected to the pipe 107. The front and rear side walls of the valve housing 501 are connected to and fixedly connected to a delivery pipe 502. The end of the delivery pipe 502 away from the valve housing 501 is connected to and fixedly connected to a spinneret 6. A valve core 503 is rotatably connected inside the valve housing 501. A T-shaped cavity 504 is carved inside the valve core 503. A pressure relief component 7 is fixedly connected to the lower side wall of the valve core 503.

[0058] When the pipe 107 rotates, it drives the valve housing 501 to rotate. This, in turn, drives the two spinneret assemblies 6 to rotate via the valve housing 501 and the delivery pipe 502, effectively replacing the two spinneret assemblies 6. If the blockage occurs in the previous spinneret assembly 6, once the replaced spinneret assembly 6 connects to the T-cavity 504, the pressure inside the pump housing 102 decreases. At this point, the rotational torque of the fixed cylinder 201 returns to normal. The fixed cylinder 201 then resets via a torsion spring, aligning the magnet 204 with the magnetic plug 206. Under magnetic force, the magnetic plug 206 moves and resets, and the push rod 208 no longer engages with the external... The inner wall of the cylinder 209 is in contact, preventing the fixed cylinder 201 from driving the outer cylinder 209 to rotate via the push rod 208 when rotating. Consequently, the outer cylinder 209 will not drive the pulley 303 to rotate via the belt 304, keeping the valve housing 501 stationary. Simultaneously, the friction between the sealing ring between the valve housing 501 and the valve core 503 is used to fix the valve housing 501. The sealing ring is horizontally fixed to the upper and lower ends of the valve core 503. The sealing ring is not shown in the figure, but it is similar to the ball valve structure in the prior art. Finally, the replacement and fixation of the spinneret assembly 6 are achieved by fixing the valve housing 501.

[0059] The implementation principle of the non-linear moisture-absorbing and quick-drying multifunctional fine denier nylon filament production equipment in this application embodiment is as follows: During normal use, the raw material is conveyed through the raw material extrusion component 1, so that the raw material can be squeezed into a fixed shape when passing through the spinneret component 6. When the resistance of conveying increases, the detection component 2 drives the transmission component 3 and the replacement component 5 to directly replace the spinneret component 6.

[0060] Example 2

[0061] Reference Figure 5-8 The difference between this embodiment and embodiment 1 is that when the source of the blockage is not the spinneret assembly 6, the power will be automatically turned off until the staff comes to conduct further inspection and maintenance.

[0062] Reference Figure 6The power-off assembly 4 includes a switch cylinder 401 fixedly connected to the side wall of the fixed box 101. A rotating rod 302 is inserted into the switch cylinder 401. A circular plate 402 is fixedly connected inside the switch cylinder 401. A square rod 403 is inserted into the circular plate 402. The circular plate 402 can restrict the square rod 403 from rotating. A return spring 404 is fixedly connected between the end of the square rod 403 near the pulley 303 and the side wall of the pulley 303. A threaded groove 405 is carved into the inner side wall of the rotating rod 302. A short rod 406 located inside the threaded groove 405 is fixedly connected to the side wall of the square rod 403. When the threaded groove 405 rotates, it will drive the short rod 406 to move. The groove 405 is designed so that when the second bevel gear 307 drives the first bevel gear 301 to rotate one revolution, the short rod 406 moves through the threaded groove 405, allowing the square rod 403 to press the switch button 407 through the spherical airbag 408. The switch button 407, which is electrically connected to the motor 104, is fixedly connected to the inner wall of the end of the switch cylinder 401 away from the fixed box 101. The spherical airbag 408 is fixedly connected to the end of the square rod 403 near the switch button 407. The spherical airbag 408 can play a buffering role, effectively preventing the square rod 403 from making hard contact with the switch button 407 due to excessive rotation of the pulley 303, which would damage the switch button 407.

[0063] When the pulley 303 rotates, it drives the rotating rod 302 to rotate, which in turn drives the short rod 406 to move through the threaded groove 405 on the inner wall of the rotating rod 302, and then drives the square rod 403 to move. After the spinneret 6 is replaced, the pressure inside the pump housing 102 is reduced, indicating that the previous spinneret 6 was blocked. Under the reset of the torsion spring 203, the rotating shaft 202 and the fixed cylinder 201 no longer cross. At this time, the magnet block 204 and the magnetic plug 206 are attracted together again under the action of magnetic force, so that the outer cylinder 209 no longer contacts the top rod 208. The square rod 403 will be reset under the action of the reset spring 404. When the square rod 403 is reset, it will drive the pulley 303 to rotate. Since the one-way bearing 306 is a one-way bearing, the pulley 303 will not drive the second bevel gear 307 to rotate through the guide rod 305.

[0064] Reference Figure 8 The spinneret 6 includes a pressure box 601 fixedly connected to the lower end of the conveying pipe 502. A spinneret plate 602 is fixedly connected to the lower end of the pressure box 601. The spinneret plate 602 has multiple evenly distributed spinneret holes 603, which can squeeze the conveyed raw material into a cross shape, increase the gap between nylon monofilaments, and improve the moisture absorption and quick-drying performance of nylon monofilaments.

[0065] Even after the spinneret 6 is replaced, the pressure inside the pump housing 102 remains unchanged, and the torque of the rotating fixed cylinder 201 is still relatively large. Therefore, the shaft 202 and the fixed cylinder 201 will continue to be misaligned, and the outer cylinder 209 will continue to contact the push rod 208. The outer cylinder 209 will continue to drive the pulley 303 and the rotating rod 302 to rotate via the belt 304, causing the rotating rod 302 to drive the short rod 406 and the square rod 403 to move through the threaded groove 405 until the spherical airbag 408 presses the switch button 407 to turn off the power to the motor 104, waiting for the staff to come and conduct further testing.

[0066] Reference Figure 7 The pressure relief assembly 7 includes a pressure relief pipe 701 fixedly connected to the lower side wall of the valve core 503. The lower end of the pressure relief pipe 701 is connected to a thick pipe 702. The thick pipe 702 is fixedly connected to the anti-leakage plate 108 through multiple support rods 703. A spring plate 704 is fixedly connected inside the thick pipe 702. A sealing plate 705 is fixedly connected to the upper side wall of the spring plate 704. A thrust spring 706 is fixedly connected between the sealing plate 705 and the spring plate 704.

[0067] When the spinneret 6 rotates, the pressure relief component 7 can relieve pressure, preventing excessive pressure inside the pump housing 102 from damaging the gear 103. During the replacement of the two spinnerets 6, the material inside the pump housing 102 cannot be discharged and the pressure becomes too high. When the pressure reaches a certain level, the thrust spring 706 is compressed a certain distance, so that some material will be discharged through the pressure relief pipe 701 and the thick pipe 702 to the anti-leakage plate 108, which effectively protects the gear 103.

[0068] A method for producing irregularly shaped, moisture-wicking, quick-drying, multifunctional fine denier nylon filament:

[0069] S1. Add raw material, which is polyamide fiber, into the raw material heating box 105. Heat the raw material into a liquid state, i.e. a gel state, through the raw material heating box 105. Then, start the motor 104 and inject the liquid raw material into the spinneret 6 through the raw material extrusion component 1.

[0070] S2. Under pressure, the liquid raw material is squeezed into multiple cross-shaped nascent fibers through multiple spinneret holes 603 inside the spinneret assembly 6, and the wind force generated by the air duct 110 is used to gradually solidify and shape these nascent fibers.

[0071] S3. After the staff observes the two spinneret assemblies 6 being rotated and replaced, the replaced spinneret assemblies 6 are inspected by the testing equipment, and finally cleaned by the ultrasonic cleaning equipment. After cleaning, the spinneret assemblies 6 are installed.

[0072] S4. Multiple nascent fibers are rotated and wound together using a synthesis device to synthesize a single nylon monofilament. After multiple cross-shaped nascent fibers are synthesized into a single nylon monofilament, a large number of gaps remain inside the monofilament, thereby improving the moisture absorption performance of the nylon monofilament. After the nylon monofilament is packaged into rolls, subsequent dyeing and fabric production processes are carried out.

[0073] The implementation principle of Example 2 is as follows:

[0074] When the spinneret 6 is replaced, the resistance to the material transport decreases, and production continues. However, when the resistance to the material transport remains high after the spinneret 6 is replaced, the power is cut off directly through the power-off component 4, and the equipment is left for further inspection by the staff.

[0075] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
