Description

Technical Field

[0001] This invention relates to the field of chemical fiber production equipment technology, and in particular to a system for cleaning impurities from a dye-free ultra-black fiber spinneret. Background Technology

[0002] The dye-free super black fiber is a functional special fiber spun by directly adding high-concentration carbon black masterbatch and inorganic auxiliaries to the spinning solution. It has significant advantages such as high color fastness, good sun resistance, short production process and no dyeing wastewater discharge.

[0003] However, as Figure 1 As shown, because carbon black masterbatch contains a large number of nano-sized carbon black particles, inorganic fillers, and polymeric dispersants, these substances gradually deposit on the inner wall of the spinneret, the surface of the spinneret, and within the micropores during continuous spinning, forming a hard and difficult-to-remove composite impurity layer. This impurity layer can lead to problems such as spinneret blockage, uneven fiber output, increased fiber breakage rate, and increased fiber fineness deviation, seriously affecting fiber product quality and production efficiency. Typically, the continuous service life of spinnerets used for dye-free super black fibers is short.

[0004] However, in actual use, the inventors found that manual disassembly was extremely inefficient, labor-intensive, and lacked control over the striking force, which could easily cause damage to the spinneret and deformation of the micropores. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a dye-free ultra-black fiber spinneret reuse impurity cleaning system. This system can achieve automated feeding, precise disassembly, classified temporary storage, multi-stage deep cleaning, and automatic conveying of spinneret components. The cleaning effect is thorough, environmentally friendly, and pollution-free, which can significantly improve the reuse rate of spinnerets and spinnerets. It has important practical significance for improving the reuse rate of spinneret components and reducing production costs.

[0006] To address the above technical problems, the following technical solution is adopted: A system for cleaning impurities from a dye-free ultra-black fiber spinneret, comprising: The disassembly and feeding device includes a separation mechanism for automatically separating the spinneret and the spinneret plate in the spinneret assembly to be cleaned, a first temporary storage and conveying mechanism for receiving the disassembled spinneret plate and conveying it to the subsequent work station and stacking it neatly according to a preset rule, and a second temporary storage and conveying mechanism for receiving the disassembled spinneret and conveying it to the subsequent work station and stacking it neatly according to a preset rule.

[0007] As an improvement, the separation mechanism includes a first worktable, a self-centering three-jaw chuck unit that is horizontally slidably mounted on the first worktable via a first linear guide pair, an induction heating component that is located directly above the self-centering three-jaw chuck unit and reciprocates vertically via a second linear guide pair, an elastic buffer adapter cylinder that is coaxially fixed to the end of the first bracket and coaxially arranged with the self-centering three-jaw chuck unit, and a first pneumatic push rod assembly that is located outside the discharge end of the elastic buffer adapter cylinder and fixedly mounted on the first worktable.

[0008] As an improvement, the separation mechanism further includes a sequential feeding assembly disposed on the other side of the self-centering three-jaw chuck unit relative to the first pneumatic push rod assembly, the sequential feeding assembly comprising: The feeding hopper includes an integrally formed and interconnected vertical storage hopper section and an inclined guiding hopper section; The receiving component has an arc-shaped receiving groove at its upper end that matches the outer diameter of the spinneret assembly. It is rotatably mounted on the first worktable via a slewing bearing and is driven to rotate intermittently by a stepper motor. The outer side of the arc-shaped receiving groove is higher than the inner side, so as to laterally limit the spinneret assembly that slides down from the outlet and prevent it from falling out. The second pneumatic push rod assembly is located on one side of the receiving component, and its pushing direction coincides with the axis of the self-centering three-jaw chuck unit. It is used to coaxially push a single spinneret assembly in the arc-shaped receiving groove to the clamping position of the self-centering three-jaw chuck unit.

[0009] As an improvement, the first pneumatic push rod assembly, the receiving bin, the self-centering three-jaw chuck unit, the elastic buffer adapter cylinder, and the second pneumatic push rod assembly are arranged coaxially in sequence along the same horizontal axis.

[0010] As an improvement, the first temporary storage conveying mechanism is used to receive and stack spinnerets, and includes: The first transmission unit includes a first flat belt conveyor and two sets of first guide baffles arranged symmetrically in a figure-eight shape on both sides of the first flat belt conveyor and extending along its conveying direction. The sorting unit includes a third pneumatic push rod assembly disposed at the output end of the first transmission unit and whose pushing direction is perpendicular to the conveying direction of the first transmission unit, and a fourth pneumatic push rod assembly disposed at the output end of the third pneumatic push rod assembly and whose pushing direction is perpendicular to the pushing direction of the third pneumatic push rod assembly. Both the third pneumatic push rod assembly and the fourth pneumatic push rod assembly are fixedly installed on the second worktable. The second transmission unit is located at the output end of the third pneumatic push rod assembly, and its transmission direction is perpendicular to the transmission direction of the first transmission unit. The first pneumatic gripper assembly is mounted on the second three-axis translation device and is used to grip the spinnerets on the second transmission unit one by one and neatly stack them in the first standard tray according to the preset stacking rules.

[0011] As an improvement, the second temporary storage conveying mechanism is used to receive and stack spinnerets, and includes: The third transmission unit includes a second flat belt conveyor, two sets of second guide baffles arranged symmetrically in a figure-eight shape on both sides of the second flat belt conveyor and extending along its conveying direction, and an axial positioning pin set at the output end of the second flat belt conveyor. The second pneumatic gripper assembly is mounted on the dual-axis translation device via a rotary joint. It is used to grip the spinnerets that have been axially positioned on the third transmission unit one by one and neatly stack them in the second standard tray according to a preset stacking rule. The fourth transmission unit is located below the second pneumatic gripper assembly and is used to drive the second standard pallet to move outward gradually along the conveying direction of the third transmission unit.

[0012] As an improvement, the system also includes a conveying device whose running track covers all stations of the first temporary storage conveying mechanism, the second temporary storage conveying mechanism, and the multi-stage deep cleaning device, for conveying the palletized first and second standard pallets to the corresponding stations of the segmented quenching and calcining mechanism, the high-pressure flushing mechanism, and the ultrasonic cleaning mechanism.

[0013] As an improvement, the quenching and calcining mechanism includes a calcining furnace and a porous air distribution plate fixedly laid on the inner wall of the calcining furnace; The porous air distribution plate forms a closed annular pressure equalization air inlet chamber with the inner wall of the calcining furnace. High-purity nitrogen output from the external nitrogen protection system is introduced into the annular pressure equalization air inlet chamber. After pressure equalization, it is evenly diffused to the heating working area of ​​the calcining furnace through the ventilation holes on the porous air distribution plate. Multiple ventilation holes are evenly distributed in a matrix on the perforated air distribution plate, and each ventilation hole has an inclined through-hole structure that is tilted towards the center of the heating working area of ​​the calcining furnace, with an inclination angle of 15°-30°.

[0014] As an improvement, the high-pressure flushing mechanism includes a vibrating plate, a flushing groove mounted on the vibrating plate, and a high-pressure rotary nozzle assembly disposed above the flushing groove, wherein the high-pressure rotary nozzle assembly is mounted on a first three-axis translation device. As an improvement, the high-pressure flushing mechanism also includes a high-pressure plunger pump with an output pressure of 50-80 MPa; As an improvement, the high-pressure rotary nozzle assembly includes 4-6 high-pressure fan-shaped nozzles that can rotate continuously in 360°. The high-pressure water output by the high-pressure plunger pump forms a fan-shaped water jet through the high-pressure fan-shaped nozzles, which can thoroughly wash away the inorganic ash and loose calcined products remaining on the inner wall of the spinneret, the surface of the spinneret plate, and the micro-orifice inlet.

[0015] As an improvement, it also includes an ultrasonic cleaning mechanism for deeply removing residual insoluble inorganic impurities and microparticles in micropores through ultrasonic cavitation effect. The mechanism includes a stainless steel ultrasonic cleaning tank, a multi-frequency ultrasonic generator connected to the bottom of the stainless steel ultrasonic cleaning tank, an immersion electric heating component, and a vacuum hot air drying oven located on one side of the stainless steel ultrasonic cleaning tank.

[0016] The beneficial effects of this invention are: (1) The present invention employs a three-stage deep cleaning process consisting of quenching and calcination, high-pressure water jet rinsing, and multi-frequency ultrasonic cleaning, which can sequentially remove organic polymers, carbon black deposits, inorganic ash, and residual microparticles in micropores, resulting in a high cleaning rate. The cleaned spinneret and spinneret have a high surface finish, are free from oxidation and discoloration, and can be reused multiple times, thus improving the reuse rate. (2) By setting up a disassembly and feeding device, the invention realizes the full-process automated control of feeding the spinneret assembly one by one, induction heating disassembly, classification and temporary storage, automatic conveying and multi-level cleaning. No manual intervention is required. More than 100 sets of spinneret assemblies can be processed in a single shift, and the production efficiency is improved compared with manual cleaning. (3) In this invention, the disassembly method of local softening of adhesive by induction heating combined with self-centering three-jaw chuck and loosening separation, combined with flat pushing force control technology, is accurate and avoids damage to the connection of the spinneret assembly and micropores caused by traditional violent disassembly. Nitrogen protection is used during the calcination process to prevent high-temperature oxidation of the spinneret assembly and extend its service life. In summary, this equipment integrates functions such as disassembly, temporary storage, transportation, and cleaning into one unit, with smooth connections between each process and a small footprint.

[0027] Figure 10 This is a structural diagram of the storage components. Detailed Implementation

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] Example 1 like Figure 2-4 As shown, a system for cleaning impurities from a dye-free ultra-black fiber spinneret includes: The disassembly and feeding device 1 includes a separation mechanism 11 for automatically separating the spinneret 101 and the spinneret plate 102 in the spinneret assembly 100 to be cleaned, a first temporary storage and conveying mechanism 12 for receiving the disassembled spinneret plate and conveying it to the subsequent work station and stacking it neatly according to a preset rule, and a second temporary storage and conveying mechanism 13 for receiving the disassembled spinneret and conveying it to the subsequent work station and stacking it neatly according to a preset rule. The multi-stage deep cleaning device 2 includes, along the material flow direction, a segmented quenching and calcining mechanism 21 for high-temperature pyrolysis of residual organic polymers, carbon black and additive deposits on the inner wall of the spinneret, the surface of the spinneret and the micropores, and a high-pressure flushing mechanism 22 for high-pressure jet flushing to remove residual inorganic ash and loose deposits after calcination.

[0030] It should be noted that the spinneret has a boss structure and is interference-fitted with the spinneret cylinder.

[0031] Furthermore, such as Figure 5 As shown, the separation mechanism 11 includes a first worktable 111, a self-centering three-jaw chuck unit 112 that is horizontally slidably mounted on the first worktable 111 via a first linear guide pair 117, an induction heating component 113 that is located directly above the self-centering three-jaw chuck unit 112 and reciprocates vertically via a second linear guide pair 118, an elastic buffer adapter cylinder 114 that is coaxially fixed to the end of the first bracket 119 and coaxially arranged with the self-centering three-jaw chuck unit 112, and a first pneumatic push rod assembly 115 that is located outside the discharge end of the elastic buffer adapter cylinder 114 and fixedly mounted on the first worktable 111.

[0032] It should be noted that by setting the elastic buffer adapter 114 in conjunction with the first guide baffle 1212 of the first transmission unit 121, the spinneret 102 pushed out by the first pneumatic push rod assembly 115 enters the elastic buffer adapter 114 for position guidance and limitation, and falls smoothly into the first transmission unit 121, so that the feeding is stable and the direction is controllable.

[0033] As an improvement, the self-centering three-jaw chuck unit is driven to rotate by a servo motor, which can achieve precise clamping and fixation of the spinneret assembly.

[0034] As an improvement, the induction heating component 113 uses a high-frequency induction heating coil, with the heating temperature controlled at 150-200℃ and the heating time at 30-60 seconds.

[0035] It should be noted that an interference fit utilizes the dimensional difference between two components. The spinneret is slightly larger than the inner wall of the spinneret tube, and a tight fit is achieved by pressing it in with external force. After assembly, a clamping force is generated between the shaft and the hole, achieving a fixing effect. When the connection is heated, the metal expands due to the heat, and the inner diameter of the hole increases accordingly. The shaft component, however, experiences less heat and expands less. When the inner diameter of the hole expands to be larger than the outer diameter of the shaft, the original interference fit becomes a clearance fit, and the clamping force between the components is significantly reduced, allowing for easy disassembly.

[0036] Furthermore, such as Figure 2-4As shown, the separation mechanism 11 further includes a sequential feeding assembly 116 disposed on the other side of the self-centering three-jaw chuck unit 112 relative to the first pneumatic push rod assembly 115. The sequential feeding assembly 116 includes: The feeding bin 1161 includes an integrally formed and interconnected vertical storage bin section 1161a and an inclined guiding bin section 1161b; The receiving component 1162 has an arc-shaped receiving groove 1162a at its upper end that is adapted to the outer diameter of the spinneret assembly. It is rotatably mounted on the first worktable 111 via a slewing bearing and is driven to rotate intermittently by a stepper motor. The outer side of the arc-shaped receiving groove 1162a is higher than the inner side to provide lateral restraint for the spinneret assembly that slides out of the outlet, preventing it from coming out. It should be noted that when the receiving component 1162 rotates toward the feeding bin 1161, the spinneret 100 located at the output end of the inclined guide bin section 1161b enters into the arc-shaped receiving groove 1162a of the receiving component 1162, the receiving component 1162 resets, and the arc-shaped solid part of the receiving component 1162 limits and blocks the output end of the inclined guide bin section 1161b.

[0037] The second pneumatic push rod assembly 1164 is disposed on one side of the receiving member 1162, and its pushing direction coincides with the axis of the self-centering three-jaw chuck unit 112. It is used to coaxially push a single spinneret assembly in the arc-shaped receiving groove 1162a to the clamping position of the self-centering three-jaw chuck unit 112.

[0038] As an improvement, the second pneumatic push rod assembly 1164 is also used to push the spinneret in the heated spinneret assembly out of the spinneret tube.

[0039] Furthermore, the first pneumatic push rod assembly 115, the receiving bin 1163, the self-centering three-jaw chuck unit 112, the elastic buffer adapter cylinder 114, and the second pneumatic push rod assembly 1164 are arranged coaxially along the same horizontal axis.

[0040] Furthermore, the first temporary storage and conveying mechanism 12 is used to receive and stack spinnerets, and includes: The first transmission unit 121 includes a first flat belt conveyor 1211 and two sets of first guide baffles 1212 arranged symmetrically in a figure-eight shape on both sides of the first flat belt conveyor 1211 and extending along its conveying direction, which can guide and correct the spinneret. Sorting unit 122 includes a third pneumatic push rod assembly 1221 disposed at the output end of the first transmission unit 121 and whose pushing direction is perpendicular to the conveying direction of the first transmission unit 121, and a fourth pneumatic push rod assembly 1222 disposed at the output end of the third pneumatic push rod assembly 1221 and whose pushing direction is perpendicular to the pushing direction of the third pneumatic push rod assembly 1221. The third pneumatic push rod assembly 1221 and the fourth pneumatic push rod assembly 1222 are both fixedly installed on the second workbench 125. In this process, the sorting unit 122 outputs spinnerets with different front and back states one by one, and then uses the existing detection equipment of the flipping clamping assembly 120 to identify and flip them so that the larger diameter is facing up and the smaller diameter is facing down, thereby improving the high-temperature calcination effect.

[0041] The second transmission unit 123 is disposed at the output end of the third pneumatic push rod assembly 1221, and its transmission direction is perpendicular to the transmission direction of the first transmission unit 121. A flip clamping assembly 120 is disposed between the second transmission unit and the third pneumatic push rod assembly. The first pneumatic gripper assembly 124 is mounted on the second three-axis translation device 126 and is used to grip the spinnerets on the second transmission unit 123 one by one and neatly stack them in the first standard tray 128 according to the preset stacking rules.

[0042] As an improvement, the first pneumatic gripper assembly 124 is mounted on the second three-axis translation device 126, which can achieve precise movement in the X, Y and Z directions, clamping the spinnerets on the second transmission unit 123 one by one and neatly arranging them in a 10×10 array in the first standard tray 129.

[0043] Furthermore, such as Figure 6 As shown, the second temporary storage and conveying mechanism 13 is used to receive and stack spinnerets, and includes: The third transmission unit 131 includes a second flat belt conveyor 1311, two sets of second guide baffles 1312 arranged symmetrically in a figure-eight shape on both sides of the second flat belt conveyor 1311 and extending along its conveying direction, and an axial positioning pin 1313 disposed at the output end of the second flat belt conveyor 1311. The axial positioning pin 1313 is used to position the output position of the spinneret. The second pneumatic gripper assembly 132 is mounted on the dual-axis translation device 135 via a rotary joint 134. It is used to grip the spinnerets that have been axially positioned on the third transmission unit 131 one by one and neatly stack them in the second standard tray 139 according to a preset stacking rule. The fourth transmission unit 133 is located below the second pneumatic gripper assembly 132 and is used to drive the second standard pallet to move outward gradually along the conveying direction of the third transmission unit 131.

[0044] It should be noted that the first guide baffle 1212 and the second guide baffle 1312 are both designed to achieve horizontal output of the spinneret and spinneret.

[0045] As an improvement, the second pneumatic gripper assembly clamps and flips the spinneret positioned on the third transmission unit 131 so that it is in a vertical position and neatly stacked in a 15×15 array in the second standard tray.

[0046] The fourth transmission unit 133 uses a screw drive mechanism to move the slide plate, and the second standard pallet is placed on the slide plate to achieve full-load stacking of the second standard pallet.

For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows: Furthermore, the system also includes a conveying device 3, the running track of which covers all the workstations of the first temporary storage conveying mechanism 12, the second temporary storage conveying mechanism 13 and the multi-stage deep cleaning device 2, for conveying the palletized first standard pallet and second standard pallet to the corresponding workstations of the segmented quenching and calcining mechanism 21, the high-pressure flushing mechanism 22 and the ultrasonic cleaning mechanism 23.

[0048] As an improvement, the conveying device 3 can be equipped with a robotic arm.

[0049] Not limited to the above-mentioned robotic arm transfer method, as an improvement, the conveying device 3 adopts a truss-type automatic conveying device, including a truss track, a traveling trolley, and a lifting robotic arm. The truss track covers all workstations of the first temporary storage conveying mechanism 12, the second temporary storage conveying mechanism 13, and the multi-stage deep cleaning device 2. The traveling trolley can move horizontally along the truss track, and the lifting robotic arm can achieve vertical lifting and pallet gripping, sequentially conveying the first and second standard pallets that have been stacked to each cleaning workstation.

[0050] As an improvement, this system also includes a PLC control system, which is electrically connected to the disassembly and feeding device 1, the multi-stage deep cleaning device 2 and the conveying device 3 respectively, and can realize the automated operation, parameter setting, status monitoring and fault alarm of the entire system.

[0051] Example 3 like Figure 7As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 3 and Embodiment 1 is as follows: Furthermore, the quenching and calcining mechanism 21 includes an electrically heated segmented calcining furnace 211 and a porous air distribution plate 212 fixedly laid on the inner wall of the calcining furnace 211; The porous air distribution plate 212 and the inner wall of the calcining furnace 211 form a closed annular pressure equalization air inlet chamber 213. The high-purity nitrogen output from the external nitrogen protection system is introduced into the annular pressure equalization air inlet chamber 213. After being equalized, it is evenly diffused to the heating working area of ​​the calcining furnace 211 through the ventilation holes 214 on the porous air distribution plate 212. Multiple ventilation holes 214 are evenly distributed in a matrix on the porous air distribution plate 212, and each ventilation hole 214 has an inclined through hole structure that is inclined towards the center of the heating working area of ​​the calcining furnace 211, with an inclination angle of 15°-30°.

[0052] As an improvement, the porous air distribution plate 212 is made of 304 stainless steel plate and is laid on the inner side wall of the calcining furnace 211, forming an annular pressure equalization air intake chamber 213 between it and the furnace wall.

[0053] As an improvement, the high-purity nitrogen output from the external nitrogen protection system, with a purity of ≥99.99%, is introduced into the annular pressure equalization inlet chamber 213. After pressure equalization, it is evenly diffused into the heating working area of ​​the calcining furnace through the ventilation holes 214 on the porous air equalization plate 212.

[0054] As an improvement, the ventilation holes 214 are evenly distributed in a matrix, with a diameter of 8 mm and a spacing of 50 mm. Each ventilation hole is tilted 20° toward the center of the furnace cavity, which can form a uniform nitrogen atmosphere in the furnace cavity and effectively prevent the high-temperature oxidation of the spinneret assembly.

[0055] Example 4 like Figure 8 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as those in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 4 and Embodiment 1 is as follows: Furthermore, the high-pressure flushing mechanism 22 includes a vibrating plate 221, a stainless steel flushing groove 222 mounted on the vibrating plate 221, and a high-pressure rotary nozzle assembly 223 disposed above the stainless steel flushing groove 222. The high-pressure rotary nozzle assembly 223 is mounted on the first three-axis translation device 225.

[0056] As an improvement, the vibratory plate 221 can drive the flushing tank 222 to generate high-frequency vertical vibration, thereby creating a momentary suspension state between the spinneret and the spinneret tube and the standard tray, so that the high-pressure rotating nozzle assembly 223 can thoroughly flush and clean them.

[0057] Furthermore, the high-pressure rotary nozzle assembly 223 can automatically adjust the nozzle position and angle according to the size and shape of the spinneret assembly, and the sprayed material is dry ice.

[0058] Example 5 like Figure 1 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as those in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below.

[0059] As an improvement, the stainless steel ultrasonic cleaning tank 231 has a volume of 500L and contains a sodium hydroxide alkaline cleaning solution with a mass concentration of 4%.

[0060] As an improvement, the immersion electric heating element uses a stainless steel heating tube with a power of 15kW, which can precisely control the temperature of the cleaning fluid at 70±2℃.

[0061] Example 6 Components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as those in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 6 and Embodiment 1 is as follows: A system for cleaning impurities from a dye-free, ultra-black fiber spinneret, with the following specific workflow: Loading and Disassembly: The spinnerets to be cleaned are batched into the vertical storage bin section 1161a of the feeding bin 1161. The spinnerets slide down the inclined guide bin section 1161b to the receiving bin 1163, and then fall into the arc-shaped receiving groove 1162a of the receiving component 1162. The receiving component 1162 rotates to align the spinnerets with the self-centering three-jaw chuck unit 112, and the second pneumatic push rod assembly 1164 pushes the spinnerets to the chuck clamping position.

[0062] The self-centering three-jaw chuck unit 112 clamps the spinneret assembly, and the induction heating unit 113 descends to the outer shaft of the spinneret assembly connection for localized heating. After heating is completed, the self-centering three-jaw chuck unit 112 moves toward the second pneumatic push rod assembly 1164, which pushes the spinneret plate from front to back and slides it down along the elastic buffer adapter cylinder 114 onto the first flat belt conveyor 1211 of the first temporary storage conveyor mechanism 12.

[0063] Next, the self-centering three-jaw chuck unit 112 moves toward the first pneumatic push rod assembly 115, the self-centering three-jaw chuck unit 112 releases the spinneret, the first pneumatic push rod assembly 115 pushes the spinneret out, and the spinneret is pushed onto the second flat belt conveyor 1311 of the second temporary storage conveyor mechanism 13. Sorting, Temporary Storage, and Palletizing: The spinnerets are conveyed to the output end via the first flat belt conveyor 1211. The third pneumatic pusher assembly 1221, in conjunction with the fourth pneumatic pusher assembly 1222, separates the spinnerets one by one and identifies the front and back sides. Finally, they are sent to the second transmission unit 123, where the first pneumatic gripper assembly 124 clamps each spinneret group and stacks them in the first standard pallet.

[0064] Synchronously, the spinnerets are conveyed to the output end via the second flat belt conveyor 1311, and the axial positioning pin 1313 is inserted into the spinnerets for positioning. The second pneumatic gripper assembly 132 clamps each spinneret and flips it to a vertical position before stacking it in the second standard pallet. When the pallet is full, it is conveyed to the material picking station of the conveying device 3.

[0065] Multi-stage deep cleaning: The conveying device 3 sequentially transports the fully loaded pallet to the segmented quenching and calcining mechanism 21, the high-pressure flushing mechanism 22, and the ultrasonic cleaning mechanism 23 for cleaning treatment.

[0066] Quenching and calcination: The tray enters the calcination furnace 211, where organic polymers and carbon black deposits are pyrolyzed into gases and ash at high temperature. At the same time, the nitrogen protection system continuously supplies nitrogen to prevent the spinneret assembly from oxidizing.

[0067] High-pressure flushing: The calcined tray enters the high-pressure flushing tank 222. The vibrating plate 221 drives the flushing tank to vibrate at high frequency, and the high-pressure rotating nozzle group 223 sprays out high-pressure water jets to flush away the residual inorganic ash in all directions.

[0068] Ultrasonic cleaning and drying: After rinsing, the tray enters the ultrasonic cleaning tank 231 for deep cleaning and rinsing, and finally enters the vacuum hot air drying oven for drying.

[0069] Discharge: After cleaning and drying, the conveyor 3 transports the tray to the discharge station, where the cleaned spinneret and spinneret plate are removed manually or automatically and then reassembled for reuse.
