Abstract
Description
Technical Field
[0001] This invention relates to the field of maintenance technology for chemical fiber spinning equipment, specifically to an online laser plate cleaning device that allows continuous spinning, which is particularly suitable for spinning box areas with limited space and obstructions from pipe columns. Background Technology
[0002] Chemical fiber spinning is an industrial manufacturing process that produces continuous chemical fibers by melting or dissolving fiber-forming polymers such as polyester and polyamide into a fluid, extruding it through micropores in a spinneret, and then cooling, stretching, and heat setting. It is mainly divided into three categories: melt spinning, wet spinning, and dry spinning. It is widely used in textiles, industrial materials, medical fields, etc. Currently, the mainstream adopts continuous and automated production lines, with melt spinning as the main production method. The production process focuses on issues such as fluid stability, uniform forming, consistent fiber performance, and low consumption and environmental protection. It is a core and fundamental link in the modern textile and new materials industry.
[0003] In the chemical fiber spinning process, the spinneret is the core component that determines the quality of fiber formation. Its surface is uniformly distributed with tens to thousands of micron-sized micropores. Under high pressure, the spinning melt is extruded through the micropores of the spinneret to form continuous filaments, which are then cooled and stretched to produce finished fibers. During long-term continuous production, low-molecular-weight volatiles, impurities, and thermal degradation products of the melt at high temperatures gradually deposit on the inner walls and surface of the spinneret's micropores, forming melt residues and coking deposits. This leads to reduced micropore size, blockage, or uneven filament output, resulting in quality problems such as broken fibers, fuzzy fibers, and defects, seriously affecting the stability of spinning production and the product qualification rate. Therefore, the spinneret needs to be cleaned regularly to maintain its normal working condition.
[0004] Traditional spinneret cleaning methods mostly involve manual cleaning after machine shutdown or offline mechanical cleaning, which suffers from drawbacks such as production interruption, low efficiency, high labor intensity, and difficulty in controlling cleaning accuracy. Existing online spinneret cleaning technologies often employ mechanical scraping or high-temperature burning, which can easily damage the microporous structure of the spinneret and cannot achieve precise cleaning while spinning continues, failing to meet the demands of the chemical fiber industry for efficient, continuous, and high-quality production. Therefore, developing an automated, high-precision, and non-destructive online spinneret cleaning device that can achieve cleaning without stopping spinning is of great significance for improving the efficiency and quality of chemical fiber production.

[0007] Preferably, a cleaning component is provided on the top of the wire pushing assembly. The cleaning component includes a cleaning head and a drive module for adjusting the displacement of the cleaning head. The lower end of the cleaning head is provided with a rotating adsorption roller for rotation and a positioning cleaning seat sleeved in the rotating adsorption roller for positioning, for automated cleaning of the surface of the laser cleaning head.
[0008] Preferably, the drive module includes a vertically connected longitudinal push rod and a transverse push rod. The longitudinal push rod is vertically mounted on the wire pusher assembly, and the telescopic end of the transverse push rod extends above the laser cleaning head for intelligent switching of laser cleaning head cleaning operations.
[0009] Preferably, the cleaning head includes a drive motor disposed at the telescopic end of the transverse top rod, and a rotary joint is disposed at the lower end of the drive motor. The rotating end of the rotary joint is connected to the drive motor and the rotating adsorption roller, and the stationary end of the rotary joint is connected to the positioning cleaning seat for dust removal of the laser cleaning head.
[0010] Preferably, the rotating adsorption roller has a ring structure, the top of the rotating adsorption roller is provided with a protective cover with an opening facing downwards, the lower end of the rotating adsorption roller is provided with a gathering part, and an elastic sleeve is provided on the outer side of the rotating adsorption roller, and a wool loop is provided on the outer side of the elastic sleeve for electrostatic adsorption to remove impurities.
[0011] Preferably, the diameter of the protective cover is larger than the diameter of the loop, the height of the protective cover is less than half the height of the rotating adsorption roller, the rotating adsorption roller is made of rubber material, and the loop is made of fabric.
[0012] Preferably, the positioning cleaning seat is provided with a water outlet and an air outlet in the middle. The outer side of the rotary joint is provided with a water supply pipe that is connected to the water outlet and an air supply pipe that is connected to the air outlet. An air pump is connected to the outside of the air supply pipe for mixed cleaning of the laser cleaning head surface in a dry and wet manner.
[0013] Preferably, the laser cleaning system includes two reflectors located inside the laser cleaning head and distributed at an angle, and the fiber laser is distributed opposite to one of the reflectors, and the two reflectors are rotated for use. A light-transmitting mirror is provided on the top of the laser cleaning head for comprehensive cleaning of the spinneret surface in both the horizontal and vertical directions.
[0014] How to use the plate cleaning device: Equipment positioning and placement: The carrier trolley is used to move the position of the cleaning device and precisely park the carrier trolley at the target spinning position to complete the initial position calibration; the robot arm carrying the laser cleaning head is moved to the safe area outside the spinneret station to be cleaned, and the equipment position is ready; Pre-treatment and straightening of the spinning bundle: The robotic arm drives the laser cleaning head to move to a position diagonally below the target spinneret position. The push rod on the pushing assembly extends synchronously, pushing the spinning bundle at the corresponding spinning position forward by a preset length. The spinning bundle is separated from the laser cleaning head without stopping spinning, ensuring the continuity of spinning production, maintaining a safe distance between the spinning bundle and the laser cleaning head, and stably straightening the two ends of the spinning bundle from the spinneret. Laser scanning cleaning operation: The laser cleaning head uses a combination of fiber laser and galvanometer system to emit a laser beam that forms a cleaning area. The laser beam is emitted through a lens and directed at the spinneret. By adjusting the angle and direction of the reflector, the laser scanning range covers the entire micro-orifice area of the spinneret. It precisely targets impurities such as melt residue and coking material in the micro-orifice of the spinneret, and uses laser irradiation to achieve non-contact vaporization and decomposition, thus completing the online cleaning of the micro-orifice of the spinneret. Multi-station continuous cleaning and space avoidance: After cleaning a single spinneret station, a robotic arm exits the station and moves to the next adjacent spinneret station with the laser cleaning head. To address the issue of limited space at the edge of the spinneret station, a path planning approach of "moving to the outer station first + rotating and cleaning obliquely with the angle adjustment seat" is adopted to avoid collisions between the robotic arm and the spinneret station structure. Equipment Reset and Recycling: After all spinnerets at the target spinning station have been cleaned, the robotic arm carrying the laser cleaning head is reset to the initial position, and the carrier trolley moves to the next set of target spinning stations. The above steps are repeated to achieve online spinneret cleaning without interrupting spinning on the entire production line. Gas cleaning and impurity collection: The horizontal push rod in the drive module moves the cleaning head above the laser cleaning head, and the vertical push rod brings the lower end of the cleaning head into contact with the lens of the laser cleaning head. Through the cooperation of the drive motor and the rotary joint, the positioning cleaning seat can blow air or spray a small amount of liquid onto the surface of the lens. When the positioning cleaning seat blows air onto the lens, the gas separates impurities from the surface of the lens. With the rotation of the drive motor, the rotating adsorption roller can centrifugally adhere to the elastic sleeve and wool coil for collection, completing dry cleaning. The small amount of liquid sprayed onto the lens by the positioning cleaning seat wets the wool coil. The rotating wool coil wetly rotates and cleans stubborn stains on the surface of the lens, adhering and collecting them. Finally, the drive module separates the laser cleaning head from the lens, completing the cleaning and impurity transfer.
[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides an online laser plate cleaning device for continuous spinning, which has the following beneficial effects: This non-stop spinning online laser cleaning device uses a carrier trolley as a mobile device. With the help of a robotic arm and an angle adjustment seat, the device can accurately position and adjust the posture of the laser cleaning head. The inclined push rod on the push assembly can push the spinning bundle away from above the laser cleaning head. In conjunction with the air intake, the spinning bundle is limited, allowing the laser cleaning head to be exposed in the working space for cleaning impurities on the spinneret surface.
[0016] This non-stop spinning online laser cleaning device, through the use of a cleaning component set on the top of the yarn pushing assembly, can rotate and clean impurities that fall onto the surface of the laser cleaning head, as well as collect the cleaned impurities, realizing automated cleaning and intelligent switching of the surface of the laser cleaning head 6.
[0017] This non-stop spinning online laser plate cleaning device, by simultaneously setting dry and wet cleaning modes on the cleaning component, facilitates the cleaning component's adaptation to different operating environments. Utilizing high-pressure gas or a combination of high-pressure gas and a small amount of liquid, it simultaneously cleans dust and stubborn sticky impurities from the laser cleaning head, and can be dried without affecting subsequent cleaning work. It also ensures laser emission accuracy and adapts to different types of impurity cleaning needs, further improving cleaning effect and process versatility. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.
[0034] Please see Figure 1-10This embodiment provides an online laser cleaning device for continuous spinning, which is used to clean melt residue and coking material on the spinneret during the continuous production of chemical fiber spinning, and to improve problems such as uneven yarn output. Using an existing online spinning workshop carrier trolley 1 as the mobile device, a robotic arm 2 (e.g., an existing Cartesian coordinate robotic arm with 3-6 axes) is mounted on top of the carrier trolley 1. The height of the robotic arm 2 is adjusted to serve as a displacement device. Next, an angle adjustment seat 3 is used at the end of the robotic arm 2. The angle adjustment seat 3 is driven to rotate by an internal motor. A yarn pushing assembly 4 is mounted on the rotating end of the angle adjustment seat 3, and a laser cleaning head 6 is mounted on the outer side of the yarn pushing assembly 4. By controlling the rotation direction and angle of the motor, the angle of the yarn pushing assembly 4 and the laser cleaning head 6 can be adjusted around the angle adjustment seat 3 as the axis, thus adjusting their working posture corresponding to the spinneret. Simultaneously, a yarn pushing rod 5, inclined towards the laser cleaning head 6, is used on the top of the yarn pushing assembly 4. An air intake 8 is mounted on the outer side of the yarn pushing rod 5. In some embodiments, the yarn pushing rod 5 can be rotatably mounted on the yarn pushing assembly 4 to adjust the angle between it and the laser cleaning head 6, and push... The length of the lead screw 5 is greater than the length of the laser cleaning head 6. As a yarn bundle pushing structure, the lead screw 5 is adjusted to push the yarn bundle and the laser cleaning head 6 to expose the laser cleaning head 6 for subsequent cleaning. The air intake 8 is externally connected to the air pump 26. The negative pressure of the air pump 26 creates a negative pressure at the outer opening of the air intake 8, which makes the pushed yarn bundle adhere to the air intake 8, restricting the position of the yarn bundle and preventing it from becoming tangled. This increases the cleanliness and quality of the yarn bundle production, allowing for continuous spinning without interruption. During the cleaning process, the laser cleaning head 6, in conjunction with the fiber laser 7 and the galvanometer system 9, achieves precise cleaning of the spinneret micropores without stopping the machine, greatly improving production efficiency. Furthermore, laser cleaning does not damage the micropore structure of the spinneret, ensuring the service life of the spinneret and the quality of yarn output. It avoids interruption of yarn bundle production during cleaning, improves cleaning accuracy, and meets the high-efficiency, continuous, and high-quality production needs of chemical fiber textile workshops.
[0035] Furthermore, after the laser cleaning head 6 has been working for a period of time, impurities and a small amount of melt residue will adhere to its surface. To ensure the cleaning quality and safety of the laser cleaning head 6, a cleaning component 12 can be installed on the top of the wire pushing assembly 4. The cleaning component 12 includes a cleaning head 15 and a drive module for adjusting the displacement of the cleaning head 15. The drive module includes a vertically connected longitudinal push rod 13 and a transverse push rod 14 (the longitudinal push rod 13 and the transverse push rod 14 can be telescopic devices such as electric push rods or cylinders). The longitudinal push rod 13 is vertically installed on the wire pushing assembly 4. During the use of the transverse push rod 14, the movement threshold of the telescopic end of the transverse push rod 14 is greater than the distance between it and the laser cleaning head 6, so that it can extend above the laser cleaning head 6 when telescopic, moving the cleaning head 15 above the laser cleaning head 6. The drive module drives the position of the cleaning head 15 to move, which is convenient for cleaning the laser cleaning head 6. It can also be quickly moved away from above the laser cleaning head 6, realizing the intelligent switching between cleaning and working of the laser cleaning head 6.
[0036] Next, the cleaning head 15 uses a drive motor 16 fixedly connected to the telescopic end of the transverse top rod 14 as a driving device. A rotary joint 17 is fixedly installed at the lower end of the drive motor 16. The power output end of the drive motor 16 is fixedly connected to the rotating end of the rotary joint 17. The lower end of the rotating end is connected to the rotating adsorption roller 18, so that the drive motor 16 can drive the rotating adsorption roller 18 to rotate synchronously when cleaning, which can realize rotation cleaning and centrifugal collection of dust. When setting the structure of the rotating adsorption roller 18, the rotating adsorption roller 18 is set as a ring structure. The top of the rotating adsorption roller 18 uses a protective cover 20 with an opening facing downward. The lower end of the rotating adsorption roller 18 is set as a gathering part 21. The outer side of the rotating adsorption roller 18 is covered with an elastic sleeve 22 of rubber material. The outer side of the elastic sleeve 22 is provided with a wool loop 23 of fabric structure. The protective cover 20 on the top of the rotating adsorption roller 18 prevents impurities from splashing during cleaning. The diameter of the protective cover 20 is larger than the diameter of the loop 23, ensuring it fully covers the working area of the loop 23. The height of the protective cover 20 is less than half the height of the rotating adsorption roller 18, so it does not affect the fit between the loop 23 and the laser cleaning head 6, ensuring normal cleaning operation. The converging part 21 at the lower end of the rotating adsorption roller 18 allows the bottom of the roller 18 to fit more closely to the corners of the laser cleaning head 6, ensuring thorough cleaning. The elastic sleeve 2 on the outer side of the rotating adsorption roller 18... 2. It can adaptively adjust according to the surface curvature of the laser cleaning head 6 to further improve the fit; by utilizing the elastic characteristics of the rubber material, the elastic sleeve 22 has good elasticity and fit. In conjunction with the fabric structure loop 23 on the outside of the elastic sleeve 22, it can adsorb small impurities on the surface of the laser cleaning head 6 through electrostatic action, adsorb and clean the impurities on the surface of the laser cleaning head 6, collect the cleaned impurities, and prevent impurities from falling onto the spinning bundle or spinneret to ensure the cleanliness of the cleaning process, while avoiding damage to the laser cleaning head 6 and improving the impurity cleaning effect.
[0037] Meanwhile, the stationary end of the rotary joint 17 is set as the positioning cleaning seat 19. The positioning cleaning seat 19 is used stationary when the cleaning head 15 is cleaning impurities. Then, a water outlet and an air outlet are opened in the middle of the positioning cleaning seat 19. A water supply pipe 24 is connected to the water outlet on the outer side of the rotary joint 17, and an air supply pipe 25 is connected to the air outlet. An air pump 26 is connected to the outside of the air supply pipe 25 (the air pressure delivered by the air pump 26 is suitable for cleaning impurities in the laser cleaning head 6). A water source is connected to the outside of the water supply pipe 24. By turning on the air pump 26 or delivering a small amount of water, it is convenient to perform mixed cleaning of the surface of the laser cleaning head 6 using both dry and wet methods. During dry cleaning, the air pump 26 delivers high-pressure gas to the air supply pipe 25, and the air outlet of the positioning cleaning seat 19 sprays high-speed gas towards the laser cleaning head 6. High-speed gas impacts the surface of the laser cleaning head 6, causing impurities to separate from the surface. As the gas flows, it rushes towards the protective cover 20. The impurities are adhered to by the rotating adsorption roller 18 or thrown to the inner wall of the protective cover 20 for collection, achieving dry cleaning of the surface of the laser cleaning head 6. During wet cleaning, a small amount of liquid is delivered to the outlet, and the air pump 26 delivers gas in conjunction with the synchronous delivery of a small amount of water. This allows the liquid to be sprayed out with the high-speed gas, simultaneously rinsing the laser cleaning head 6. The small amount of liquid wets the loops 23 on the surface of the rotating adsorption roller 18, removing stubborn stains from the surface of the laser cleaning head 6 and enhancing the cleaning effect on sticky impurities. Then, the gas is blown again to dry the liquid on the surface of the laser cleaning head 6, and at the same time dry the loops 23, making it convenient for the cleaning head 15 to repeat the cleaning work.
[0038] To achieve the cleaning of impurities on the spinneret, in some embodiments, the galvanometer system 9 uses two angled reflectors 10 as the laser emission direction adjustment structure. The two reflectors 10 are installed inside the laser cleaning head 6. The fiber laser 7 is distributed opposite to one of the reflectors 10. The top of the laser cleaning head 6 is sealed and protected by a light-transmitting mirror 11, which facilitates the penetration and irradiation of the laser. During the use of the laser cleaning head 6, a motor is used as an angle driving device at one end of the reflector 10. By adjusting the operating angle of the two reflectors 10 by the motor, the laser emitted by the fiber laser 7 can be emitted, passing through the light-transmitting mirror 11 and directed towards the spinneret. Then, by controlling the rotation angle and rotation range of the motor through the control system, the rotation adjustment of the two reflectors 10 is achieved, changing the laser reflection direction, thereby adjusting the laser irradiation angle and range, so that the laser can cover the entire surface of the spinneret, achieving comprehensive cleaning of the spinneret surface in both the horizontal and vertical directions, and improving the comprehensiveness and uniformity of the cleaning of the spinneret.
[0039] When cleaning the spinneret using a spinneret cleaning device, the following steps can be performed: Equipment positioning and placement: Through the movement control of the carrier trolley 1, the carrier trolley 1 can travel along the preset path of the spinning production line in the chemical fiber workshop and accurately stop at the target spinning position to complete the initial position calibration; then, with the cooperation of the robot arm 2 and the angle adjustment seat 3, the laser cleaning head 6 is moved to the safe area outside the spinneret station to be cleaned, and the pusher assembly 4 and the laser cleaning head 6 are adjusted to the appropriate angle, and the equipment position is ready; Pre-treatment and straightening of the spinning bundle: The robotic arm 2 drives the laser cleaning head 6 to move to a position diagonally below the target spinneret position. The push rod 5 on the push assembly 4 extends synchronously, pushing the spinning bundle at the corresponding spinning position forward to a preset length, so that the spinning bundle separates from the laser cleaning head 6 while spinning continues. The air pump sets the outside of the air inlet 8 to a negative pressure environment, and the spinning bundle adheres to the air inlet 8 and the push rod for stable positioning, providing working space for the laser cleaning head 6, ensuring the continuity of spinning production, maintaining a safe distance between the spinning bundle and the laser cleaning head 6, and at the same time, the two ends of the spinning bundle are stably straightened between the spinneret and the ends of the spinning bundle. Laser scanning cleaning operation: The laser cleaning head 6 uses the fiber laser 7 and galvanometer system 9 in combination. The laser beam emitted by the fiber laser 7 forms a cleaning area and is emitted towards the spinneret through the light transmission lens 11. The angle and direction of the motor at the end of the reflector 10 are adjusted so that the laser scanning range covers the entire micro-hole area of the spinneret. The laser beam is precisely applied to the melt residue, coking material and other impurities in the micro-holes of the spinneret in a reciprocating manner. The laser irradiation is used to achieve non-contact vaporization and decomposition, and the online cleaning of the micro-holes of the spinneret is completed. Multi-station continuous cleaning and space avoidance: After cleaning a single spinneret station, the robot arm 2 exits the station and moves with the laser cleaning head 6 to the next adjacent spinneret station to repeat the cleaning work; In response to the problem of narrow space at the edge of the spinneret station, a path planning of "first move to the outer station + angle adjustment seat 3 to rotate and clean obliquely" is adopted to avoid collision between the robot arm 2 and the spinneret station structure and increase the stability of the cleaning work; Equipment reset and recycling: After all the spinnerets at the target spinning station have been cleaned, the robotic arm 2 carrying the laser cleaning head 6 is reset to the initial position, and the carrier trolley 1 moves to the next set of target spinning stations, so that the above steps can be repeated to achieve online cleaning of the entire production line without stopping spinning. Gas cleaning and impurity collection: When the equipment is used for a long time, the horizontal push rod 14 in the drive module can be used to move the cleaning head 15 above the laser cleaning head 6, and the vertical push rod 13 can be used to bring the lower end of the cleaning head 15 into contact with the light transmission lens 11 of the laser cleaning head 6. Through the cooperation of the drive motor 16 and the rotary joint 17, the air pump 26 uses the positioning cleaning seat 19 to blow air onto the surface of the light transmission lens 11 for dry cleaning, or a small amount of liquid can be introduced through the water pipe 25 for wet cleaning. During dry cleaning, when the positioning cleaning seat 19 blows air onto the light transmission lens 11, the gas separates the impurities from the surface of the light transmission lens 11. With the rotation of the drive motor 16, the rotating adsorption roller 18 can centrifugally adhere the impurities to the elastic sleeve 22 and the wool loop 2. 3. During dry cleaning, some impurities will remain inside the protective cover 20, thus achieving impurity collection and completing dry cleaning and impurity collection. During wet cleaning, a small amount of liquid is sprayed onto the light-transmitting mirror 11 through the positioning cleaning seat 19 while the gas is being delivered. The liquid is sprayed onto the laser cleaning head 6, and the small amount of liquid can wet the wool coil 23. The rotating wool coil 23 performs wet rotation cleaning on the stubborn stains on the surface of the light-transmitting mirror 11 and collects the adhering impurities. Then, by spraying gas again, the laser cleaning head 6 and the wool coil 23 can be dried. The impurities are collected inside the wool coil 23 and the protective cover 20, completing wet cleaning and impurity collection. Finally, the drive module separates the laser cleaning head 6 from the light-transmitting mirror 11, completing cleaning and impurity transfer.
