[0002] After a period of time, high-temperature polyester melt is squeezed out of the micropores of the spinneret by pressure, and coke that affects the spinning quality will form on the spinneret surface, so the spinneret surface must be cleaned regularly. The traditional practice is to manually clean the spinneret when the spinning is stopped. When the spinneret is stopped, the temporary stop of a metering pump will cause fluctuations in the internal pressure of the elbow and the pressure difference between the inlet and outlet of other metering pumps, which will directly affect the spinning quality. Summary of the invention

[0026] At the same time, a laser cleaning mechanism is used to emit a laser to the plate surface of the spinneret to perform laser cleaning on the plate surface of the spinneret;

[0027] According to the cleaning plan route, move to the next spinneret station and repeat the above steps until all spinnerets are cleaned.

[0028] Preferably, the laser cleaning mechanism emits laser to the surface of the spinneret to clean the surface of the spinneret by laser, comprising:

At the same time, the laser cleaning mechanism emits laser to the plate surface of the spinneret, and a mobile method can be adopted to make the laser cleaning mechanism emit laser to various positions of the spinneret, gasify the coke particles on the plate surface of the spinneret, and discharge them out of the workshop through air flow. According to the workshop conditions, the cleaning process route can be planned, and each spinneret can be cleaned one by one to achieve the purpose of cleaning the spinneret without stopping spinning.

[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] See also Figure 1 and Figure 2 As shown, this embodiment is a laser cleaning device for a non-stop spinning chemical fiber spinneret 4, comprising:

[0052] The yarn recovery mechanism 8 is used to suck the fiber yarn 5 in the spinneret 4 into a bundle;

[0053] A laser cleaning mechanism, used for emitting laser to the plate surface of the spinneret 4, so as to perform laser cleaning on the plate surface of the spinneret 4;

[0054] The oil and gas output mechanism is used to blow off the bundled fiber yarns sucked out by the suction funnel so that the suction recovery mechanism 8 can absorb the recovered fiber yarns, and output the silicone oil release agent to the spinneret 4.

[0055] When cleaning the spinneret 4 in this embodiment, the wire suction recovery mechanism 8 can be placed under the spinneret 4, and the fiber yarn in the spinneret 4 is first sucked by the wire suction recovery mechanism 8, so that the fiber yarn is sucked out into bundles, wherein the wire suction recovery mechanism 8 can have various suction principles and shapes, and can be set according to various different shapes and sizes of spinnerets 4, and the principle of the wire suction recovery mechanism 8 can also have various suction methods. For example, the wire suction recovery mechanism includes a wire suction funnel and a suction module, and the suction module can use negative pressure to perform suction.

[0056] After being sucked by the above-mentioned suction funnel, the fiber yarns sucked out of the suction funnel are blown off by the oil and gas output mechanism, and the blown-off fiber yarns enter the suction recovery mechanism 8 for recovery. At the same time, the laser cleaning mechanism emits laser to the plate surface of the spinneret 4, and the laser cleaning mechanism can be moved to emit laser to various positions of the spinneret 4 to gasify the coke particles on the plate surface of the spinneret 4 and discharge them out of the workshop through air flow.

[0057] By adopting the above method, it is possible to clean each spinneret 4 on each spinning position one by one while the spinning process is in operation without stopping the spinning process.

[0058] In this embodiment, the oil and gas output mechanism may have various structural forms. For example, in one embodiment, the oil and gas output mechanism includes:

[0059] The air knife nozzle 6 is used to output a high-pressure airflow to blow off the fiber yarns sucked out of the suction funnel into bundles;

[0060] The silicone oil gas nozzle 7 is used to output oil mist gas containing silicone oil release agent.

[0061] In this embodiment, an oil and gas output mechanism can be set next to the wire suction recovery mechanism 8, and a high-pressure airflow is output through the wind knife air nozzle 6 in the oil and gas output mechanism, thereby blowing off the bundled fiber yarns sucked out of the wire suction funnel. Under the action of gravity and the absorption force of the wire suction recovery mechanism 8, the blown-off fiber yarns fall into the wire suction recovery mechanism 8.

[0062] The silicone oil nozzle 7 can output oil mist gas containing silicone oil release agent, which can take away the waste silk slurry hanging on the spinneret 4 and blow away cleaning impurities during laser cleaning.

[0063] In this embodiment, the laser cleaning mechanism has various structural forms, and various existing structural forms can be adopted. In one embodiment, the laser cleaning mechanism includes:

[0064] Laser galvanometer, used for emitting laser;

[0065] The laser channel 2 is used to output the laser emitted by the laser galvanometer to the plate surface of the spinneret 4, and is arranged obliquely relative to the laser galvanometer lens 11 of the laser galvanometer.

[0066] like Figure 3 As shown, in this embodiment, when the spinneret 4 is cleaned, since it is located below the spinneret 4, by emitting laser from bottom to top, in order to prevent the chemical fiber waste and the like on the spinneret 4 from falling onto the laser galvanometer lens 11 and contaminating the laser galvanometer lens 11 during the cleaning process, therefore, in this embodiment, the laser channel 2 is arranged obliquely relative to the laser galvanometer lens 11 of the laser galvanometer, so that the laser emitted to the surface of the spinneret 4 is incident obliquely, and the generated chemical fiber waste and other impurities fall freely from the other side of the laser channel 2, thereby avoiding contamination of the laser galvanometer lens 11.

[0067] In one embodiment, it further includes:

[0068] The waste yarn collecting tank 3 is used to receive the chemical fiber waste yarns remaining on the spinneret 4 after the recovery fiber yarns are sucked by the recovery mechanism 8 .

[0069] If the waste chemical fiber yarns blown off by the air knife nozzle are not sucked away by the yarn suction recovery mechanism 8, they can also be collected by the waste yarn collection tank 3, which can improve the cleaning effect.

[0070] In one embodiment, the waste wire collection groove 3 is located above the laser galvanometer, and the laser channel 2 separates the waste wire collection groove 3 and the wire suction recovery mechanism 8 and the oil and gas output mechanism into two sides, so that the wire suction recovery mechanism 8 and the oil and gas output mechanism are located on one side of the laser channel 2, and the waste wire collection groove 3 is located on the other side of the laser channel 2.

[0071] In this embodiment, when cleaning, it can move along the surface of the spinneret 4 to clean various positions on the surface of the plate. After being sucked by the suction recovery mechanism 8, the fiber yarns sucked out of the suction funnel are blown off by the oil and gas output mechanism so that the suction recovery mechanism 8 can absorb and recover the fiber yarns, and output silicone oil release agent to the spinneret 4. At the same time, the laser cleaning mechanism performs laser cleaning, and then the waste silk collection tank 3 further receives the remaining waste silk, thereby completing cleaning and recycling. Among them, the generated chemical fiber waste silk and other impurities fall freely from the other side of the laser channel 2, which can be seen in Figure 3 The black triangle area shown is used to avoid contamination of the laser galvanometer lens 11 .

[0072] In one embodiment, it further includes:

[0073] Robot for moving and adjusting the laser cleaning angle.

[0074] In this embodiment, a robot operation method can be adopted to move and adjust the laser cleaning angle through the robot. The robot can have many forms, which will not be described in detail here.

[0075] In one embodiment, the laser cleaning mechanism further includes a laser cable channel 10, and the laser cable channel 10 is mounted on a robot connecting flange 9 connected to the robot.

[0076] In this embodiment, a robot connecting flange 9 can be installed on the laser cable channel 10, and connected to the robot through the robot connecting flange 9. The robot connecting flange 9 is arranged on the laser cable channel 10, so that the structure is compactly installed, space is saved, and it is easy to disassemble and assemble.

[0077] In this embodiment, the inclination angle of the laser channel 2 relative to the laser galvanometer lens 11 of the laser galvanometer can be changed according to actual conditions. In one embodiment, the inclination angle of the laser channel 2 relative to the laser galvanometer lens 11 of the laser galvanometer is 70 degrees.

[0078] In order to further illustrate the cleaning working mode of the above-mentioned non-stop spinning chemical fiber spinneret 4 laser cleaning device, the present invention also provides a non-stop spinning chemical fiber spinneret 4 laser cleaning method using the above-mentioned non-stop spinning chemical fiber spinneret 4 laser cleaning device, comprising:

[0079] At the first spinneret 4 station in the working area, the fiber yarn in the spinneret 4 is first sucked out into a bundle by the suction recovery mechanism 8;

[0080] The fiber yarns sucked out of the suction funnel into bundles are blown off by the oil and gas output mechanism so that the suction recovery mechanism 8 can absorb the recovered fiber yarns, and the silicone oil release agent is output to the spinneret 4;

[0081] At the same time, a laser cleaning mechanism is used to emit a laser to the plate surface of the spinneret 4 so as to perform laser cleaning on the plate surface of the spinneret 4;

[0082] According to the cleaning plan route, move to the next spinneret 4 station and repeat the above steps until all spinnerets 4 are cleaned.

[0083] In this embodiment, the cleaning planning route can be set according to actual needs. For example, when cleaning several spinnerets 4 in a spinning position, it is possible to start from the spinneret 4 at one end of the spinning position and clean the spinnerets 4 at the other end one by one.

[0084] In this embodiment, the laser beam is emitted at an angle of 70 degrees, and a triangular blind area is generated at the four corners of the spinneret (see Figure 8 ), which cannot be cleaned under normal circumstances. Therefore, in one embodiment, the laser cleaning mechanism emits laser to the plate surface of the spinneret 4 to perform laser cleaning on the plate surface of the spinneret 4, including:

[0085] The laser channel 2 of the laser cleaning mechanism is arranged obliquely relative to the laser galvanometer lens 11 of the laser galvanometer to prevent the chemical fiber waste falling freely from the spinneret 4 from falling onto the laser;

[0086] During laser cleaning, when cleaning the two ends of the spinneret 4 respectively, the laser cleaning device for the non-stop spinning chemical fiber spinneret 4 is rotated to a set angle so that the laser emitted by the laser channel 2 vertically penetrates into the two ends of the spinneret 4, thereby cleaning the cleaning blind areas at both ends of the spinneret 4.

[0087] like Fig. 9 and Fig.10 As shown, in this embodiment, when the spinnerets 4 at both ends are cleaned respectively, the angle can be rotated, for example, to 20 degrees, to complete the blind area cleaning, and then return to the position and work normally. When running to the other end of the spinneret 4, the laser galvanometer rotates 20 degrees in the opposite direction of the working direction to clean the blind area, and then returns to the normal working posture after completion.

[0088] Several spinnerets 4 are arranged in a spinning position, and the maximum distance from the edge of the spinneret 4 at both ends to the side baffle is generally only 50 mm, while the width of the laser galvanometer is much larger than 50 mm, so it is impossible to start working in the direction of the arrow. Figure 4Therefore, in one embodiment, the laser cleaning mechanism emits laser to the surface of the spinneret 4 to clean the surface of the spinneret 4 by laser, including:

[0089] When cleaning several spinnerets 4 in one spinning position, if the distance from the spinnerets 4 at both ends of the spinning position to the side baffle is less than the width of the laser galvanometer, then at the spinneret 4 station at the head end, the laser cleaning device for the non-stop spinning chemical fiber spinneret 4 is rotated 90 degrees, that is, the spinneret 4 at the head end is cleaned along the depth of the laser galvanometer;

[0090] After the spinneret 4 at the head end is cleaned, the laser cleaning device for the non-stop spinning chemical fiber spinneret 4 is rotated 90 degrees and returned to the lateral position, and the spinneret 4 is cleaned along the lateral direction of the laser galvanometer until the spinneret 4 at the end is cleaned. Then, the laser cleaning device for the non-stop spinning chemical fiber spinneret 4 is rotated 90 degrees, that is, it moves forward along the longitudinal depth of the laser galvanometer to clean the spinneret 4 at the end.

[0091] In this embodiment, the robot can be rotated 90 degrees, that is, the laser galvanometer lens 11 is rotated 90 degrees, and the laser galvanometer lens 11 moves forward in depth to clean the first spinneret 4. Figure 5 After completing the cleaning work of the first spinneret 4, the robot rotates 90 degrees, returns to normal working state, and cleans the next spinneret 4 horizontally. Figure 6 After reaching the last spinneret 4, the robot rotates 90 degrees and works in the first working position. Figure 7 Finally, the cleaning work of the spinneret 4 of one spinning position is completed.

[0092] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
