Description

Technical Field

[0001] This utility model relates to the technical field of the chemical fiber industry, specifically to a laser cleaning device for non-stop spinning chemical fiber spinnerets. Background Technology

[0002] After the high-temperature polyester melt is extruded under pressure from the micro-orifices of the spinneret and spun for a period of time, coking deposits will form on the spinneret surface, affecting the spinning quality. Therefore, the spinneret surface must be cleaned regularly. The current traditional practice is to manually clean the spinneret by scraping it when spinning is stopped. However, when cleaning the spinneret after stopping spinning, the temporary cessation of one metering pump will cause fluctuations in the internal pressure of the bend and the pressure difference between the inlet and outlet of other metering pumps, which will directly affect the spinning quality. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a laser cleaning device for spinnerets of chemical fibers that can clean the spinnerets without stopping spinning.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A laser cleaning device for non-stop spinning chemical fiber spinnerets includes:

[0006] The yarn extraction and recovery mechanism is used to draw out the fiber yarn from the spinneret and bundle it together.

[0007] A laser cleaning mechanism is used to emit a laser to the surface of the spinneret to perform laser cleaning on the surface of the spinneret.

[0008] The oil and gas output mechanism is used to blow off the bundled fiber yarns sucked out by the fiber suction and recovery mechanism so that the fiber suction and recovery mechanism can absorb and recover the fiber yarns, and output silicone oil release agent to the spinneret.

[0009] Preferably, the laser cleaning mechanism includes:

[0010] Laser galvanometer, used to emit laser light;

[0011] A laser channel is used to output the laser emitted by the laser galvanometer to the surface of the spinneret, and is arranged at an angle relative to the laser galvanometer lens.

[0012] As a preferred option, it also includes:

[0013] The waste fiber collection tank is used to receive the chemical fiber waste fibers remaining on the spinneret after the fiber recovery mechanism has absorbed and recovered the fiber yarn.

[0014] Preferably, the waste filament collection trough is located above the laser galvanometer, and the laser channel separates the waste filament collection trough, the filament suction and recovery mechanism, and the oil and gas output mechanism into two sides, so that the filament suction and recovery mechanism and the oil and gas output mechanism are located on one side of the laser channel, and the waste filament collection trough is located on the other side of the laser channel.

[0015] Preferably, the oil and gas output mechanism includes:

[0016] The air knife nozzle is used to output high-pressure airflow to break the bundle of fiber yarn sucked out by the suction funnel.

[0017] Silicone oil nozzles are used to output oil mist gas containing silicone oil release agent.

[0018] As a preferred option, it also includes:

[0019] Robots are used to move and adjust the angle of laser cleaning.

[0020] Preferably, the laser cleaning mechanism further includes a laser cable channel, on which a robot connection flange connected to the robot is mounted.

[0021] Preferably, the laser channel is tilted at an angle of 70 degrees relative to the laser mirror lens of the laser mirror.

[0022] Preferably, the wire-collecting and recycling mechanism includes a wire-collecting funnel and a suction module.

[0023] The advantages of this utility model compared with the prior art are:

[0024] In this invention, the yarn suction and recovery mechanism is placed below the spinneret. First, the yarn suction and recovery mechanism draws in the fibers from the spinneret. Then, the oil and gas output mechanism draws out bundles of yarn through the suction funnel and breaks them. The broken yarn then enters the yarn suction and recovery mechanism for recycling. Simultaneously, a laser cleaning mechanism emits a laser beam onto the surface of the spinneret. This mechanism can be moved to reach various positions on the spinneret, vaporizing any coking particles on the surface and expelling them from the workshop via airflow. The cleaning process can be planned according to the workshop conditions, cleaning each spinneret one by one, achieving continuous spinning and cleaning. This invention has a simple structure and is economical and practical. The cleaning angle can be flexibly changed, allowing for the cleaning of blind spots and improving the cleaning effect.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0040] Please see Figure 1 and Figure 2 As shown, this embodiment is a laser cleaning device for a non-stop spinning chemical fiber spinneret 4, comprising:

[0041] The yarn extraction and recovery mechanism 8 is used to draw out the fiber yarns 5 from the spinneret 4 and bundle them together.

[0042] A laser cleaning mechanism is used to emit a laser to the surface of the spinneret 4 to perform laser cleaning on the surface of the spinneret 4.

[0043] The oil and gas output mechanism is used to blow off the bundled fiber yarns sucked out by the fiber suction and recovery mechanism so that the fiber suction and recovery mechanism 8 can absorb and recover the fiber yarns, and output silicone oil release agent to the spinneret 4.

[0044] In this embodiment, when cleaning the spinneret 4, the fiber collection mechanism 8 can be placed below the spinneret 4. First, the fiber collection mechanism 8 sucks up the fiber yarn inside the spinneret 4, so that the fiber yarn is sucked out into a bundle. The suction principle and shape of the fiber collection mechanism 8 can be varied and can be set according to various shapes and sizes of spinnerets 4. The principle of the fiber collection mechanism 8 can also have various suction methods. For example, the fiber collection mechanism includes a suction funnel and a suction module. The suction module can use negative pressure to suck up the fiber.

[0045] After being drawn in by the aforementioned suction funnel, the bundled fiber yarns are then blown out by the oil and gas output mechanism. The blown-out fiber yarns then enter the suction and recovery mechanism 8 for recycling. Simultaneously, a laser cleaning mechanism emits a laser onto the surface of the spinneret 4. This laser can be moved to different positions on the spinneret 4, vaporizing the coking particles on the surface of the spinneret 4 and expelling them from the workshop through airflow.

[0046] Using the above method, the spinning process can be carried out without stopping the spinning process, and each spinneret 4 at each spinning station can be cleaned one by one while the process is in operation.

[0047] In this embodiment, the oil and gas output mechanism can have various structural forms. For example, in one embodiment, the oil and gas output mechanism includes:

[0048] The air knife nozzle 6 is used to output high-pressure airflow to blow off the bundle of fiber yarn sucked out by the suction funnel.

[0049] Silicone oil nozzle 7 is used to output oil mist gas containing silicone oil release agent.

[0050] In this embodiment, an oil and gas output mechanism can be set up next to the yarn suction and recovery mechanism 8. High-pressure airflow is output through the air knife nozzle 6 in the oil and gas output mechanism, which then sucks out the bundle of fiber yarn from the yarn suction funnel and blows it off. Under the action of gravity and the absorption force of the yarn suction and recovery mechanism 8, the blown-off fiber yarn falls into the yarn suction and recovery mechanism 8.

[0051] The silicone oil nozzle 7 can output oil mist gas containing silicone oil release agent, which can carry away the waste slurry suspended on the spinneret 4 and blow away cleaning impurities during laser cleaning.

[0052] In this embodiment, the laser cleaning mechanism can have various structural forms, and various existing structural forms can be adopted. In one embodiment, the laser cleaning mechanism includes:

[0053] Laser galvanometer, used to emit laser light;

[0054] Laser channel 2 is used to output the laser emitted by the laser galvanometer to the surface of the spinneret 4, and is arranged at an angle relative to the laser galvanometer lens 11 of the laser galvanometer.

[0055] like Figure 3 As shown, in this embodiment, when cleaning the spinneret 4, since it is located below the spinneret 4, a laser is emitted from bottom to top. In order to avoid the chemical fiber waste filaments on the spinneret 4 falling onto the laser galvanometer lens 11 during the cleaning process and contaminating the laser galvanometer lens 11, the laser channel 2 is arranged at an angle relative to the laser galvanometer lens 11 of the laser galvanometer. In this way, the laser emitted to the surface of the spinneret 4 is obliquely incident, while the generated chemical fiber waste filaments and other impurities fall freely from the other side of the laser channel 2, thereby avoiding contamination of the laser galvanometer lens 11.

[0056] In one embodiment, it further includes:

[0057] Waste yarn collection tank 3 is used to receive the chemical fiber waste yarn remaining on the spinneret 4 after the fiber yarn is absorbed and recycled by the fiber recovery mechanism 8.

[0058] If the chemical fiber waste filaments broken by the air knife nozzle are not sucked away by the filament collection mechanism 8, they can still be collected by the waste filament collection tank 3, which can improve the cleaning effect.

[0059] In one embodiment, the waste filament collection trough 3 is located above the laser galvanometer, and the laser channel 2 separates the waste filament collection trough 3, the filament suction and recovery mechanism 8, and the oil and gas output mechanism into two sides, so that the filament suction and recovery mechanism 8 and the oil and gas output mechanism are located on one side of the laser channel 2, and the waste filament collection trough 3 is located on the other side of the laser channel 2.

[0060] In this embodiment, during cleaning, the spinneret 4 can be moved along its surface to clean various locations. First, the yarn is sucked up by the yarn-absorbing and recycling mechanism 8, then the bundled fibers are blown out of the suction funnel by the oil and gas output mechanism for the yarn-absorbing and recycling mechanism 8 to collect and recycle. Silicone oil release agent is output to the spinneret 4, while a laser cleaning mechanism performs laser cleaning. Finally, the waste yarn collection tank 3 further collects the remaining waste yarn, thus completing the cleaning and recycling process. Impurities such as chemical fiber waste yarn generated fall freely from the other side of the laser channel 2. (See [reference needed]). Figure 3 The black-marked triangular area shown is to prevent contamination of the laser galvanometer lens 11.

[0061] In one embodiment, it further includes:

[0062] Robots are used to move and adjust the angle of laser cleaning.

[0063] In this embodiment, a robot can be used to operate the robot, which can move and adjust the laser cleaning angle. There are many other types of robots, which will not be described in detail here.

[0064] In one embodiment, the laser cleaning mechanism further includes a laser cable channel 10, on which a robot connection flange 9 connected to the robot is mounted.

[0065] In this embodiment, a robot connecting flange 9 can be installed on the laser cable channel 10 to connect with the robot. By placing the robot connecting flange 9 on the laser cable channel 10, the structure is compact, saves space, and is easy to assemble and disassemble.

[0066] In this embodiment, the tilt angle of the laser channel 2 relative to the laser galvanometer lens 11 of the laser galvanometer can be varied according to the actual situation. In one embodiment, the tilt angle of the laser channel 2 relative to the laser galvanometer lens 11 of the laser galvanometer is 70 degrees.

[0067] The working principle of the above-mentioned non-stop spinning chemical fiber spinneret laser cleaning device is as follows:

[0068] At the first spinneret 4 station in the work area, the fiber yarn inside the spinneret 4 is first drawn out into a bundle by the yarn suction and recovery mechanism 8.

[0069] The oil and gas output mechanism draws out bundles of fiber yarn from the suction funnel and blows them off so that the fiber yarn can be collected and recovered by the suction and recovery mechanism 8, and outputs silicone oil release agent to the spinneret 4.

[0070] Simultaneously, a laser is emitted to the surface of the spinneret 4 through a laser cleaning mechanism to perform laser cleaning on the surface of the spinneret 4;

[0071] Following the cleaning plan, move to the next spinneret 4 station and repeat the above steps until all spinnerets 4 are cleaned.

[0072] In this embodiment, the cleaning route can be set according to actual needs. For example, when cleaning several spinnerets 4 in a spinning station, you can start from the spinneret 4 at one end of the spinning station and clean them one by one to the spinneret 4 at the other end.

[0073] In this embodiment, the laser beam is emitted at a 70-degree angle, creating a triangular blind zone at the four corners of the spinneret (see...). Figure 8 Under normal circumstances, it cannot be cleaned. Therefore, the laser channel 2 of the laser cleaning mechanism is arranged at an angle relative to the laser galvanometer lens 11 of the laser galvanometer to prevent the chemical fiber waste filaments falling freely from the spinneret 4 from falling onto the laser. During laser cleaning, when cleaning both ends of the spinneret 4, 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 is perpendicularly injected into both ends of the spinneret 4, thereby cleaning the cleaning blind areas at both ends of the spinneret 4.

[0074] like Figure 9 and Figure 10 As shown, in this embodiment, when cleaning the spinnerets 4 at both ends, the angle can be rotated, for example, to 20 degrees, to complete the blind area cleaning, and then return to the normal working position. 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 position.

[0075] Several spinnerets 4 are arranged within a spinning station. The maximum distance from the edge of the spinnerets 4 at both ends to the side baffle is generally only 50mm, while the width of the laser galvanometer is much greater than 50mm, making it impossible to start working in the direction of the arrow. Figure 4 Therefore, when cleaning several spinnerets 4 in a spinning station, if the distance from the spinnerets 4 at both ends of the spinning station to the side baffle is less than the width of the laser galvanometer, then at the spinneret 4 station at the beginning, the non-spinning chemical fiber spinneret 4 laser cleaning device is rotated 90 degrees, that is, it moves along the depth of the laser galvanometer to clean the spinneret 4 at the beginning.

[0076] After the first spinneret 4 is cleaned, the laser cleaning device for the non-stop spinning chemical fiber spinneret 4 is rotated 90 degrees to return to the lateral position and cleans the spinneret 4 along the lateral direction of the laser galvanometer until it reaches the last spinneret 4. Then, the laser cleaning device for the non-stop spinning chemical fiber spinneret 4 is rotated 90 degrees to clean the last spinneret 4 along the depth of the laser galvanometer.

[0077] In this embodiment, the robot can rotate 90 degrees, thus rotating the laser galvanometer lens 11 by 90 degrees, and advance along the depth of the laser galvanometer lens 11 to clean the first spinneret 4. (See...) Figure 5 After completing the cleaning of the first spinneret 4, the robot rotates 90 degrees, returns to normal operation, and then horizontally cleans the next spinneret 4. Figure 6 After reaching the last spinneret 4, the robot rotates 90 degrees and resumes its first working posture. (See...) Figure 7 Finally, the cleaning of the spinneret 4 at one spinning station is completed.

[0078] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
