Description

Technical Field

[0001] This invention relates to a cleaning device and method for spinnerets. Background Technology

[0002] In the production of synthetic fiber filaments such as polyester filament, spinning assemblies with spinnerets are typically used, through which the filaments are extruded through numerous micro-holes. To ensure the spinnability and weight stability of the fiber filaments, the spinnerets are cleaned regularly to prevent accumulated contaminants from clogging the micro-holes and causing the equipment to malfunction. This cleaning process is commonly known as "scraping," which involves using a scraper to remove contaminants from the spinneret, thus eliminating monomers produced by the high-temperature decomposition or degradation of the polymer, as well as any coking residue from the release agent (usually silicone oil) sprayed during cleaning.

[0003] To avoid the problems associated with manual scraping, such as high skill requirements for operators, low production efficiency, impact on operator health, and uneven scraping quality, existing technologies have proposed using automated scraping robots for mobile scraping. However, these technologies still have the following drawbacks: 1. During the cleaning process, silicone oil still needs to be sprayed, which causes pollution, and the silicone oil sprayed on the panel forms coke, affecting the cleaning effect; 2. When the size of the spinneret changes, the size and position of the scraper on the automated scraping robot need to be adjusted or replaced accordingly, limiting the robot's usability; 3. The automated scraping robot can only move in a single straight line. When multiple spinning boxes of the spinning assembly are distributed in different directions, multiple scraping robots need to be configured or the scraping robots need to be manually switched, wasting manpower and affecting overall production efficiency.

[0060] The technical solutions in the embodiments of this application will now be clearly and completely described with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art. Obviously, the embodiments described in this application are only a part of the embodiments of this application, and not all of the embodiments.

[0061] See Figures 1 to 15 The illustrated spinneret cleaning device is used to clean the spinneret 102 of the spinning assembly 100, wherein, as shown... Figure 2 As shown, the spinning assembly 100 has a spinning box 101, and a spinneret panel 102 is disposed on the upper part of the spinning box 101. The spinneret panel 102 is provided with a plurality of spinneret holes 103, and each spinneret hole 103 is provided with densely packed micropores for spinning outward. This cleaning device is mainly used to clean each spinneret hole 103 on the spinneret panel 102 to prevent dirt from clogging the micropores and affecting spinning.

[0062] The cleaning equipment includes a laser cleaning device, which includes a laser main unit 3, a laser working head 5, and a robotic arm 4. The laser working head 5 is connected to the laser main unit 3 via optical fiber. The laser working head 5 has a light outlet 52 facing the spinneret panel 102. The robotic arm 4 has an installation end 41 and a free end 42 located at opposite ends along its length. The laser working head 5 is installed on the free end 42 and moves with the robotic arm 4.

[0063] The cleaning equipment also includes a guiding and carrying device, which includes a guide rail 22 and a mounting base 1. The laser cleaning device is mounted on the mounting base 1, which is suspended on the guide rail 22 and can move along the guide rail 22, thereby carrying the laser cleaning device to move along the length extension direction of the guide rail 22, and traveling relative to the length extension direction of the spinneret panel 102 of the spinning assembly 100.

[0064] When the cleaning equipment is in operation, the laser main unit 3 operates, projecting a laser beam outward from the light outlet 52 of the laser working head 5 onto the spinneret panel 102. The robotic arm 4 moves the laser working head 5, changing the relative position between the laser working head 5 and the spinneret panel 102, so that different positions along the width of the spinneret panel 102 can be cleaned by the laser beam. Simultaneously, the entire laser cleaning device moves along the guide rail 22 relative to the spinneret panel 102, thereby continuously cleaning the spinneret panel 102 along its length. This cleaning process directly uses laser to remove contaminants from the spinneret panel 102, eliminating the need for silicone oil used in traditional cleaning processes, resulting in no pollution and superior cleaning performance. Furthermore, the laser working head 5 moves with the robotic arm 4 relative to the spinneret panel 102, making it suitable for cleaning spinnerets 102 of different sizes and positions. When the position or size of the spinneret panel 102 needs adjustment, no parts of the cleaning equipment need to be replaced.

[0065] Referring to the accompanying drawings, in this embodiment, the guiding and transporting device further includes a rack 23, a gear 6, and a drive unit 60. The rack 23 and the guide rail 22 are fixedly arranged relative to each other, and the rack 23 and the guide rail 22 are spaced apart in the horizontal direction, with the distance between the rack 23 and the guide rail 22 being a constant value. The gear 6 is rotatable around its own axis. The drive unit 60 is specifically a motor. Both the gear 6 and the drive unit 60 are mounted on the mounting base 1, and the gear 6 meshes with the rack 23. When the drive unit 60 drives the gear 6 to rotate, the gear 6 meshes with the rack 23, which in turn drives the mounting base 1 to automatically move along the guide rail 22 with the laser cleaning device.

[0066] Referring to the accompanying drawings, the guiding and transporting device also includes a fixed frame 21. A rack 23 and a guide rail 22 are respectively fixed to the bottom of the fixed frame 21. The rack 23 has teeth that mesh with the gear 6, and these teeth are located on the side of the rack 23 facing away from the guide rail 22. This arrangement allows the gear 6 to be positioned on the side of the rack 23 facing away from the guide rail 22, leaving only a small gap between the guide rail 22 and the rack 23, thus reducing the need for an excessively large fixed frame 21. Furthermore, the meshing of the gear 6 and the rack 23 allows the rack 23 to withstand a certain lateral force, reducing the force during the sliding connection between the guide rail 22 and the laser cleaning device, thereby making the movement of the laser cleaning device along the guide rail 22 smoother.

[0067] Multiple fixing seats 25 are fixedly installed on the aforementioned fixed frame 21. A crossbeam 200 is installed at the top of the spinning workshop. The fixed frame 21 is fixed to the crossbeam 200 through the multiple fixing seats 25, so that the fixed frame 21 and guide rail 22 are suspended in the upper part of the workshop, forming the ceiling rail assembly 2. The laser cleaning device is correspondingly suspended in the upper space of the workshop. The spinning box 101 of the spinning assembly 100 can be arranged along the ceiling rail assembly 2 in the workshop, specifically so that the length extension direction of the spinneret 102 is as parallel as possible to the length extension direction of the guide rail 22. In this way, the laser cleaning device will not be affected by waste yarn and other objects on the ground during operation, and can move unimpeded in the air, safely and stably. Meanwhile, when cleaning and processing the existing spinning assembly 100, it is only necessary to suspend and install the ceiling rail assembly 2 in the corresponding spinning workshop, arrange its guide rail 22 along the length extension direction of the spinneret panel 102, then connect the mounting base 1 to the ceiling rail assembly 2, and then install the laser cleaning device on the mounting base 1. No changes or settings are required to the spinning assembly 100, making it convenient to add and use.

[0068] The overhead track assembly 2 also includes a power supply sliding contact line 24, which is provided with a conductive element extending along its length. The power supply sliding contact line 24 is connected to a power source. The power supply line on the laser cleaning device is slidably connected to the conductive element in the power supply sliding contact line 24, so that the power supply line of the laser cleaning device is always electrically connected to the power supply sliding contact line 24 as the laser cleaning device moves along the guide rail 22. In this way, the laser cleaning device can move freely in the spinning workshop without being restricted by the need for the power supply line to be connected to electricity.

[0069] See Figures 3 to 6 As shown, the guiding and transporting device also includes a first guiding assembly 7 with a first guiding seat 71. The first guiding seat 71 is rotatably mounted on the mounting base 1 around a first axis (not shown in the figure). The first axis extends vertically. The first guiding assembly 7 has two or more sets arranged at intervals, and all the first guiding seats 71 are slidably connected to the guide rail 22. In this way, multiple first guiding seats 71 are simultaneously slidably mounted with the guide rail 22 and simultaneously bear the weight of the laser cleaning device. At the same time, when there is a curved part in the length extension direction of the guide rail 22, the first guiding seats 71 rotate around the first axis when running to the curved part, thereby ensuring that multiple first guiding seats 71 are stably slidably mounted with the guide rail 22 at the same time, ensuring that the entire mounting base 1 can smoothly move along the length extension direction of the guide rail 22 without jamming.

[0070] Specifically, see Figure 12 As shown, each of the first guide seats 71 includes a rotating part 7a and a sliding engagement part 7b that are fixedly arranged with each other. The sliding engagement part 7b is provided with a guide groove that cooperates with the guide rail 22. The cross-section of the guide rail 22 is "I" shaped. The guide groove allows the guide rail 22 to be inserted along the length direction, thereby connecting it to the guide rail 22 in a suspended manner. The rotating part 7a is rotatably connected to the mounting base 1, and a bearing is provided between the two.

[0071] See Figures 3 to 15 As shown, the guiding and transporting device also includes a second guiding assembly 8, which has a second guiding seat 82 and a sliding seat 81. The second guiding seat 82 is rotatably mounted on the sliding seat 81 about a second axis. The second guiding assembly 8 and all the first guiding assemblies 7 are spaced apart from each other in the first direction. The sliding seat 81 is slidably mounted on the mounting base 1 in the second direction. The second guiding seat 82 is slidably connected to the guide rail 22. The first axis and the second axis are parallel to each other, and the first direction, the second direction, and the first axis / second axis are perpendicular to each other. The gear 6 is rotatably connected to the sliding seat 81 about its own axis. Correspondingly, the driving member 60 is also mounted on the sliding seat 81. The structure of the second guiding seat 82 and its connection with the guide rail 22 are similar to those of the first guiding seat 71, and will not be described in detail here.

[0072] During the process of the mounting base 1 running along the length of the guide rail 22, when the gear 6 runs to the curved part of the guide rail 22, the sliding seat 81 slides relative to the mounting base 1 in the second direction, so that the distance between the gear 6 and the rack 23 is adjusted accordingly, so that the gear 6 can always maintain meshing with the rack 23, and prevent the gear 6 from disengaging from the rack 23, thereby ensuring the automatic movement of the laser cleaning device along the entire length extension direction of the guide rail 22.

[0073] Referring to the accompanying drawings, in this embodiment, the guide rail 22 has a first straight extension segment 22a, a curved extension segment 22c, and a second straight extension segment 22b connected sequentially along its length extension direction. The length extension direction of the first straight extension segment 22a is perpendicular to the length extension direction of the second straight extension segment 22b. The length extension trajectory of the curved extension segment 22c extends in an arc shape. The first extension line where the first straight extension segment 22a is located and the second extension line where the second straight extension segment 22b is located are tangent to the arc extension line of the curved extension segment 22c.

[0074] The above-mentioned curved extension segment 22c is mainly set to realize the transition connection between the first straight extension segment 22a and the second straight extension segment 22b. In specific settings, it should be ensured that during the movement of the mounting base 1 along the guide rail 22, at most two of the first guide seats 71 and the second guide seats 72 are located on the curved extension segment 22c at the same time.

[0075] When the second guide seat 82 is engaged with the first straight extension segment 22a, the first direction extends along the length direction of the first straight extension segment 22a, and the second direction is perpendicular to the length direction of the first straight extension segment 22a; when the second guide seat 82 is engaged with the second straight extension segment 22b, the first direction extends along the length direction of the second straight extension segment 22b, and the second direction is perpendicular to the length direction of the second straight extension segment 22b; and when the second guide seat 82 is engaged with the curved extension segment 22c, the second direction extends radially along the arc extension trajectory of the curved extension segment 22c.

[0076] When the second guide seat 82 engages with the first straight extension segment 22a or the second straight segment 22b, the sliding seat 81 does not need to move along the second direction, and the gear 6 can maintain meshing with the rack 23 corresponding to the straight extension segment. However, when the second guide seat 82 engages with the curved extension segment 22c, the sliding seat 81 slides along the second direction, which is radial movement along the curved extension segment 22c, causing the gear 6 to move toward or away from the rack 23, thereby ensuring that the gear 6 and the rack 23 maintain a stable meshing state and do not disengage or jam. In this way, the spinning assembly 100 can include multiple spinning boxes 101, which can be distributed along the first straight extension segment 22a and along the second straight extension segment 22b. This allows the spinneret panels 102 on the spinning boxes 101 at different locations in the spinning workshop to be cleaned by a single laser cleaning device, facilitating the layout and space utilization of the spinning assembly 100 in the workshop and saving on the number of cleaning devices.

[0077] See here. Figure 12 As shown, the mounting base 1 is also provided with two sets of guide members 83, which are specifically guide rails. Both sets of guide members 83 extend along the second direction and are spaced apart. The two sides of the sliding base 81 are respectively slidably engaged with the two sets of guide members 83 to improve the stability and accuracy of sliding. The motor, which serves as the driving member 60, is installed below the sliding base 81. The gear 6 is located above the sliding base 81, and its axis extends vertically. The rack 23 corresponds to the curved part of the curved extension section 22c, and its teeth are set on the outwardly arched side of the curved part.

[0078] The second guide component 8 is located between the two sets of first guide components 7. When passing through the curved extension section 22c, under the action of the first guide seats 71 on both sides, the second guide seat 82 remains engaged with the guide rail 22, and moves the sliding seat 81 and its gear 6 toward or away from the guide rail 22, so that the gear 6 and the rack 23 always remain engaged, thereby making the automatic operation of the mounting base 1 along the length extension direction of the guide rail 22 more stable and reliable.

[0079] Referring to the accompanying drawings, in this embodiment, the mounting base 1 includes a first support 11 and a second support 12 fixedly connected by a rigid connector 13. The laser host 3 is suspended on the first support 11, and the robotic arm 4 is suspended on the second support 12. The laser host 3 is box-shaped and has a large overall weight. The mounting end 41 of the robotic arm 4 is connected to the second support 12.

[0080] Each of the first support 11 and the second support 12 is provided with at least two sets of first guide components 7, and a second guide component 8 is disposed on the first support 11, and is located on the first support 11 between the two sets of first guide components 7. This not only makes full use of the length of the first support 11, but also allows the motor of the drive unit 60 to be connected to the power supply of the laser host 3, etc., which facilitates the wiring layout.

[0081] The guiding and carrying device also has a positioning bar (not shown in the figure), which is set along the length of the guide rail 22. The laser cleaning device is also equipped with a scanner for acquiring position information on the positioning bar, and the scanner is communicatively connected to the drive unit 60 in the guiding and carrying device. Since the position of the guide rail 22 relative to the spinneret panel 102 is fixed, the position information on the positioning bar corresponds to the position information along the length of the spinneret panel 102. Based on the position information on the positioning bar acquired by the scanner, the corresponding position on the spinneret panel 102 can be determined. The drive unit 60 controls the gear 6 to rotate a specified number of revolutions according to the current position information and the target position information, so that the laser cleaning device can move along the guide rail 22 to the target position. This allows the entire laser cleaning device to be positioned on the guide rail 22 and to correct its deviation after running for a period of time, ensuring processing accuracy. In specific settings, the positioning bar can be fixed to the guide rail 22 or the fixed frame 21 by pasting, and the scanner can be set on the upper part of the laser host 3.

[0082] See the accompanying figures, especially Figure 7 , Figure 8 As shown, the laser working head 5 includes a body 51, which is mounted on the robotic arm 4. A connecting seat 50 is provided at the bottom of the body 51, which can be detachably connected to the free end 42 of the robotic arm 4. A connecting end 54 is also provided on one side of the body 51 for connection to the laser host 3 via an optical fiber cable. The body 51 is provided with a light output channel (not shown in the figure) for laser beam projection, and a light output port 52 is located at one end of the light output channel.

[0083] The laser working head 5 also includes a purging assembly for blowing out a gas stream containing positive and negative ions. This purging assembly is mounted on the body 51 and has an air outlet 53, which consists of multiple spaced-apart small holes. When the laser working head 5 is used in conjunction with the spinneret panel 102 for processing, both the air outlet 53 and the light emission port 52 face upwards toward the spinneret panel 102. Specifically, the purging assembly includes a fan and an ion generator capable of generating positive and negative ions. Both the fan and the ion generator are located within the cavity of the body 51. The fan is configured to blow the positive and negative ions generated by the ion generator outwards through the aforementioned air outlet 53.

[0084] In this way, by blowing a stream of positive and negative ions onto the spinneret 102 before or during laser cleaning of contaminants, static electricity on the spinneret 102 can be eliminated, avoiding the risk of fire caused by sparks generated by static electricity during laser processing. This is mainly because during the spinning process, friction occurs as the filament is extruded from the spinneret orifice 103, easily accumulating static electricity; at the same time, laser processing is a high-energy thermal processing method, which can easily generate electric sparks during processing, and the contaminants in the micropores of the spinneret 102 and most of the materials in the spinning workshop are flammable. Using laser to clean the spinneret 102 can easily cause a fire hazard. This also makes the use of laser to clean contaminants on the spinneret 102 truly widespread in actual production.

[0085] Specifically, the laser beam projected from the light outlet 52 acts on a first region on the spinneret panel 102, and the airflow containing positive and negative ions blown out from the air outlet 53 acts on a second region on the spinneret panel 102. The first region and the second region at least partially overlap. In some embodiments, the first region can be completely contained within the second region, that is, the area of ​​the spinneret panel 102 where the laser beam acts is swept by the airflow containing positive and negative ions, eliminating static electricity in the laser-acting area in real time and avoiding fire hazards. In a specific configuration, there is a gap greater than 0 between the light outlet 52 and the air outlet 53, wherein the air outlet 53 has multiple outlets spaced apart.

[0086] In this embodiment, the laser cleaning device has a control system, the specific components of which can be integrated into the housing containing the laser host 3. This control system is used at least to control the opening and closing of the laser host 3. The laser working head 5 is also equipped with a leak detector 55 for detecting biphenyl concentration, and this leak detector 55 is communicatively connected to the control system. During laser processing, if the leak detector 55 detects biphenyl in the environment, it sends a signal to the control system, which then controls the laser host 3 to shut down, stopping the laser beam emission and thus preventing a fire.

[0087] In this embodiment, a rangefinder 56 is also provided on the laser working head 5, and the robotic arm 4 has a motion controller for controlling the movement trajectory of the free end 42 of the robotic arm 4. The motion controller is communicatively connected to the rangefinder 56. The distance between the light outlet 52 and the part to be cleaned is measured by the rangefinder 56. The motion controller controls the movement of the robotic arm 4 to adjust the distance between the laser working head 5 and the part to be cleaned, so that the laser beam is projected onto the spinneret panel 102 according to preset parameters to ensure the cleaning effect.

[0088] When cleaning the spinneret panel 102 of the spinning assembly 100 using the cleaning equipment of this embodiment, the specific steps are as follows:

[0089] The laser working head 5 moves with the free end 42 of the robotic arm 4 to the bottom of the spinneret panel 102, so that the light outlet 52 faces upward toward the spinneret panel 102, and the laser beam is projected from the light outlet 52 onto the spinneret panel 102; the robotic arm 4 moves along the width direction of the spinneret panel 102 with the laser working head 5, and cleans the dirt on the spinneret panel 102 and its spinneret holes 103 in sequence along the width direction; the laser cleaning device moves along the length extension direction of the guide rail 22, so that the robotic arm 4 moves accordingly along the length direction of the guide rail 22, thereby changing the position of the laser working head 5 in the length direction of the spinneret panel 102, and cleaning and processing it in sequence along the length direction of the spinneret panel 102.

[0090] During actual processing, since the spinning assembly 100 includes multiple spinning boxes 101, when the laser cleaning device moves along the guide rail 22 to a certain set position, the robotic arm 4 can move with the laser working head 5 to clean the spinneret panel 102 on the spinning box 101 in both the length and width directions. Subsequently, the drive unit 60 moves again to make the gear 6 mesh with the rack 23, so that after the laser cleaning device moves a certain distance along the guide rail 22, the laser working head 5 can clean the spinneret panel 102 on the next spinning box 101 in both the length and width directions.

Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it. They should not be used to limit the scope of protection of the present invention.
