Description

Technical Field

[0001] This invention relates to the field of carbon fiber production equipment maintenance technology, specifically a carbon fiber spinneret cleaning device. Background Technology

[0002] As a high-performance structural material, the production quality of carbon fiber is highly dependent on the stability of the spinning process. The spinneret is the core component of the spinning machine. During the high-temperature spinning process, its thousands of micron-sized channels are easily clogged by hard, dense carbonized residues generated from the pyrolysis of the precursor fiber. This clogging can lead to yarn breakage and uneven fineness, severely affecting product quality and production efficiency. Therefore, regularly cleaning the spinneret efficiently and without damage is a key step in ensuring continuous and stable carbon fiber production.

[0003] Existing cleaning technologies are simplistic and overly crude, failing to accurately diagnose blockages during cleaning. This leads to a lack of precision in the cleaning process, resulting in either insufficient cleaning (leaving residual blockages) or over-cleaning (causing damage and resource waste). Therefore, the industry urgently needs a new method and device for spinneret cleaning that can achieve precise diagnosis and targeted cleaning to improve the quality stability and economic efficiency of carbon fiber production. Summary of the Invention

[0006] Furthermore, a cylinder for controlling the lifting and lowering of the mounting frame is fixedly installed inside the box, and a fixing plate is fixedly connected to the box. The fixing plate is located above the mounting frame, and a side plate one and a side plate two are fixedly connected to the bottom of the fixing plate.

[0007] Furthermore, both side plate one and side plate two are slidably connected to a retraction rod, and slide plate one and slide plate two are fixedly connected to the two retraction rods respectively. The top ends of slide plate one and slide plate two are slidably connected to a groove opened in the bottom surface of the fixed plate.

[0008] Furthermore, a second spring is fixedly connected between the first side plate and the first sliding plate, and a second spring is also fixedly connected between the second side plate and the second sliding plate. Both second springs are sleeved on the retraction rods, and the opposite ends of the two retraction rods are both arc-shaped surfaces.

[0009] Furthermore, a telescopic rod is provided through the top of the fixed plate, a spring is sleeved on the telescopic rod, and a conical stop block is fixedly connected to the bottom end of the telescopic rod. A lever is fixedly installed on the mounting frame. When the mounting frame is located in the ultrasonic cleaning tank, the conical stop block is located between the two retracting rods and is in contact with the arc-shaped surface of the retracting rod. When the mounting frame is raised to the highest position, the lever is located between the two retracting rods, and the top of the lever is in contact with the bottom of the conical stop block, and the side of the lever is in contact with the arc-shaped surface of the two retracting rods.

[0010] Furthermore, the mounting bracket has a sliding groove, the end of the upper jaw is slidably connected in the sliding groove, a limit rod is fixedly connected to the lower jaw, the upper middle part of the limit rod is inserted in the upper jaw, the upper part of the limit rod has a threaded part, a locking screw is threadedly connected to the threaded part, and a spring is fixedly connected between the upper jaw and the lower jaw, the spring being sleeved on the limit rod.

[0011] Furthermore, a square insert rod is rotatably connected to the first slide plate, and a square cylinder is rotatably connected to the second slide plate, with the square insert rod slidably inserted into the square cylinder.

[0012] Furthermore, the second slide plate is provided with a drive gear driven by a drive motor, a drive rod is rotatably connected to the second slide plate, a driven gear that meshes with the drive gear is fixedly connected to the drive rod, a rotating rod is rotatably connected to the first slide plate, the rotating rod is connected to the square insert rod through a transmission belt one, and the drive rod is connected to the square cylinder through a transmission belt two.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: Pressure sensors are installed in both the inner groove of the jet assembly and the air collection groove of the cleaning assembly in the present invention, which can monitor pressure data P and Q respectively. By measuring the changes in pressure data, the blockage status of the micron-level channels of the spinneret can be accurately determined, and the blockage area can be further refined. This solves the problem that the prior art cannot diagnose blockage, and the cleaning is either insufficient (residual blockage) or excessive (damage to components and waste of resources). Furthermore, the inner groove of the jet assembly can be used to treat the blockage area in a targeted manner, thereby improving the cleaning effect. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] This invention provides a technical solution: such as Figures 1-9 A carbon fiber spinneret cleaning device is shown, comprising a housing 1, on which an ultrasonic cleaning tank 2 is provided; a liftable mounting frame 3 is installed on the housing 1, and the mounting frame 3 is provided with an upper clamp 5 and a lower clamp 6, which clamp the spinneret body 7; the two ends of the spinneret body 7 are respectively provided with a synchronously rotating air jet assembly 19 and a cleaning assembly 20, the outline of the air jet assembly 19 is smaller than that of the cleaning assembly 20, the air jet assembly 19 has an inner groove 34, and the cleaning assembly 20 has an air collection groove 39 corresponding to the inner groove 34; when the air jet assembly 19 and the cleaning assembly 20 rotate synchronously, the inner groove 34 and the corresponding air collection groove 39 are always aligned in the axial direction of the spinneret body 7; the side of the cleaning assembly 20 is provided with a slanted shovel 38, and in the rotation direction of the air jet assembly 19 and the cleaning assembly 20, the angular position of the slanted shovel 38 is always ahead of the angular position jointly defined by the inner groove 34 and the air collection groove 39.

[0020] In this invention, the spinneret body 7 is clamped between the upper clamp 5 and the lower clamp 6 (the sides of the upper clamp 5 and the lower clamp 6 that contact the spinneret body 7 are made of silicone, which not only provides an anti-slip effect but also protects the spinneret body 7 from damage) and mounted on a liftable mounting frame 3. Each end face of the spinneret body 7 corresponds to an air jet assembly 19 and a cleaning assembly 20. These two assemblies can rotate synchronously. The side of the cleaning assembly 20 has a slanted shovel 38. During rotation, the slanted shovel 38 will first contact the surface of the spinneret body 7. Moreover, the inner groove 34 inside the air jet assembly 19 and the air collection groove 39 inside the cleaning assembly 20 will always be aligned in the axial direction of the spinneret body 7 and will not be misaligned. In addition, the overall outline of the jet assembly 19 is smaller than that of the cleaning assembly 20. This is because the discharge end of the spinneret body 7 has a lot of dirt, so the cleaning assembly 20 with a larger outline is used to fit this end face. The feed end has less dirt, so the jet assembly 19 with a smaller outline can fit this end face.

[0021] A cylinder 8 for controlling the lifting and lowering of the mounting bracket 3 is fixedly installed inside the housing 1. A fixing plate 4 is fixedly connected to the housing 1, located above the mounting bracket 3. Side plate 12 and side plate 2 13 are fixedly connected to the bottom of the fixing plate 4. Retraction rods 14 are slidably connected to both side plate 12 and side plate 2 13. Slide plates 17 and 18 are fixedly connected to the two retraction rods 14 respectively. The tops of slide plates 17 and 18 are slidably connected to grooves opened on the bottom surface of the fixing plate 4. A spring 2 15 is fixedly connected between side plate 12 and slide plate 17, and another spring 2 15 is fixedly connected between side plate 2 13 and slide plate 2 18. All are fitted onto the retraction rods 14, with the opposite ends of the two retraction rods 14 being arc-shaped surfaces; a telescopic rod 9 is provided through the top of the fixing plate 4, and a spring 10 is fitted onto the telescopic rod 9. A conical stop block 11 is fixedly connected to the bottom end of the telescopic rod 9. A lever 16 is fixedly installed on the mounting frame 3. When the mounting frame 3 is located inside the ultrasonic cleaning tank 2, the conical stop block 11 is located between the two retraction rods 14 and is in contact with the arc-shaped surface of the retraction rod 14. When the mounting frame 3 rises to the highest position, the lever 16 is located between the two retraction rods 14, and the top of the lever 16 is in contact with the bottom of the conical stop block 11, and the side of the lever 16 is in contact with the arc-shaped surface of the two retraction rods 14.

[0022] In this invention, cylinder 8 is installed inside housing 1 and can move the mounting bracket 3 up and down. Fixing plate 4 is fixed on housing 1 and positioned above mounting bracket 3. Side plate 12 and side plate 2 13 are also fixed to the bottom of fixing plate 4. Sliding retraction rods 14 are installed on both side plates. Sliding plate 17 and sliding plate 2 18 are respectively fitted onto the two retraction rods 14, and the tops of sliding plate 17 and sliding plate 2 18 can slide in the grooves opened on the bottom surface of fixing plate 4. Between side panel 12 and slide plate 17, and between side panel 2 and slide plate 2, spring 2 15 is fitted on the retraction rod 14. The opposite ends of the two retraction rods 14 are curved surfaces. The telescopic rod 9 passes through the top of the fixed plate 4, and spring 10 is fitted on the rod. The bottom end of the telescopic rod 9 is fixed with a conical stop block 11. The mounting bracket 3 is equipped with a lever 16. When the mounting frame 3 is inside the ultrasonic cleaning tank 2, the conical stop 11 is locked between the two retraction rods 14 and is in contact with the arc-shaped surface of the retraction rods 14, thus holding the retraction rods 14 in place (in fact, during the descent of the mounting frame 3, the jet assembly 19 and the cleaning assembly 20 do not fix the spinneret body 7, thus not affecting its descent); when the mounting frame 3 rises to the highest position, the lever 16 will move between the two retraction rods 14, lifting the conical stop 11 at the top and making its side contact with the arc-shaped surface of the retraction rods 14, so that the conical stop 11 no longer holds the retraction rods 14. The sliding plate 17 and the sliding plate 28 move towards each other under the elastic force of the spring 2 15, thereby making the jet assembly 19 and the cleaning assembly 20 fit against the end face of the spinneret body 7.

[0023] The mounting bracket 3 has a sliding groove 25. The end of the upper jaw 5 is slidably connected to the sliding groove 25. A limit rod 26 is fixedly connected to the lower jaw 6. The upper middle part of the limit rod 26 is inserted into the upper jaw 5. The upper part of the limit rod 26 has a threaded part 27. A locking screw block 28 is threaded onto the threaded part 27. A spring 3 29 is fixedly connected between the upper jaw 5 and the lower jaw 6. The spring 3 29 is sleeved on the limit rod 26. A square insert rod 21 is rotatably connected to the first slide plate 17. A square insert rod 21 is rotatably connected to the second slide plate 18. A square cylinder 23 is movably connected, and a square insert rod 21 is slidably inserted into the square cylinder 23; a drive gear 31 driven by a drive motor 30 is provided on the second slide plate 18, a drive rod 33 is rotatably connected to the second slide plate 18, and a driven gear 32 meshing with the drive gear 31 is fixedly connected to the drive rod 33; a rotating rod 36 is rotatably connected to the first slide plate 17, and the rotating rod 36 is connected to the square insert rod 21 through a first transmission belt 22; the drive rod 33 is connected to the square cylinder 23 through a second transmission belt 24.

[0024] In this invention, the mounting bracket 3 has a sliding groove 25, and the end of the upper clamp 5 can slide in the sliding groove 25. The position can be adjusted according to the size of the spinneret body 7. The lower clamp 6 has a fixed limiting rod 26, the upper part of which is inserted into the upper clamp 5. The upper part of the limiting rod 26 has a threaded part 27. By screwing the locking screw 28 onto the threaded part 27, the spinneret body 7 can be clamped between the upper clamp 5 and the lower clamp 6. Moreover, the limiting rod 26 between the upper clamp 5 and the lower clamp 6 is fitted with a spring 29, which can play a buffering role and prevent the spinneret body 7 from being damaged by clamping too tightly. A rotatable square insert rod 21 is mounted on slide plate 17, and a rotatable square cylinder 23 is mounted on slide plate 28. The square insert rod 21 can be directly inserted into the square cylinder 23. The drive motor 30 on slide plate 28 can drive the drive gear 31 to rotate. The drive gear 31 will drive the meshing driven gear 32 and drive rod 33 to rotate together. The drive rod 33 drives the square cylinder 23 to rotate through transmission belt 24. The square cylinder 23 then drives the square insert rod 21 inserted inside to rotate. The square insert rod 21 then drives the rotating rod 36 to rotate through transmission belt 22. In this way, the jet assembly 19 connected to the drive rod 33 and the sweeping assembly 20 connected to the rotating rod 36 can rotate synchronously.

[0025] The drive rod 33 has an air inlet 35 that communicates with the inner groove 34. The other end of the drive rod 33 is fixedly connected to the jet assembly 19. A pressure sensor is installed in the inner groove 34 to monitor pressure data P. The other end of the rotating rod 36 is fixedly connected to the cleaning assembly 20. The cleaning assembly 20 has an exhaust pipe 37 that communicates with the air collection groove 39. A pressure sensor is installed in the air collection groove 39 to monitor pressure data Q.

[0026] In this invention, an air inlet 35 is opened inside the drive rod 33. This air inlet 35 is connected to the inner groove 34 of the jet assembly 19. An external high-pressure air source can directly enter the inner groove 34 through the air inlet 35. A pressure sensor is installed in the inner groove 34 to monitor the pressure data P in the groove in real time. The rotating rod 36 and the cleaning assembly 20 are fixed together. The air collection groove 39 of the cleaning assembly 20 is connected to the exhaust pipe 37. A pressure sensor is also installed in the air collection groove 39 to monitor the pressure data Q in the groove. The high-pressure gas passing through the micro-holes of the spinneret body 7 will enter the air collection groove 39, which is directly opposite the inner groove 34, and finally be discharged from the exhaust pipe 37. This can prevent the gas from accumulating in the air collection groove 39 and ensure that the Q value measured by the pressure sensor is accurate. By comparing the P value of the inner groove 34 and the Q value of the air collection groove 39, the blockage of the micro-holes on the spinneret body 7 can be determined.

[0027] Working principle: First, the spinneret body 7 is clamped, then ultrasonic cleaning is performed, and finally high-pressure gas precise positioning cleaning is performed (removing moisture and specifically flushing the blocked areas). When clamping the spinneret body 7, the operator places the spinneret body 7 to be cleaned between the upper jaw 5 and the lower jaw 6. According to the thickness of the spinneret body 7, the upper jaw 5 slides into the position of the slide groove 25, and then the locking screw 28 is tightened. The locking screw 28 moves downward along the threaded part 27 of the limiting rod 26, causing the upper jaw 5 to move downward to fit against the spinneret body 7, thus completing the clamping and fixing of the spinneret body 7. During this process, the spring 3 29 is compressed, and the resulting elastic reaction force can play a buffering and energy absorption role, avoiding damage to the spinneret body 7 caused by excessive clamping force. At the same time, the limiting rod 26 can ensure that the clamping positions of the upper jaw 5 and the lower jaw 6 are always aligned, preventing the spinneret body 7 from being clamped off-center. After clamping, cylinder 8 drives mounting bracket 3 to move downwards, immersing spinneret body 7 into ultrasonic cleaning tank 2. Ultrasonic cleaning tank 2 contains cleaning agent or water, etc., and through the cavitation effect of ultrasound, it performs preliminary cleaning of the shallow, loose carbonized residues on the surface and within the micropores of spinneret body 7. This step can remove most of the easily detachable dirt. After ultrasonic cleaning, cylinder 8 drives mounting bracket 3 to move upwards. During the upward movement of mounting bracket 3, lever 16 on mounting bracket 3 gradually approaches conical stop block 11. Finally, the top of lever 16 contacts the bottom of conical stop block 11, and the side contacts the arc-shaped surfaces of the two retraction levers 14. As mounting bracket 3 continues to move upwards, lever 16 pushes the conical stop block... As the abutment 11 moves upward along the telescopic rod 9, the conical abutment 11 moves upward, and the two retracting rods 14 lose the squeezing restriction of the conical abutment 11. Under the elastic force of the second spring 15, the two retracting rods 14 move towards the middle, while driving the first slide plate 17 and the second slide plate 18 to move closer to each other. This allows the air jet assembly 19 and the cleaning assembly 20 to precisely fit against the two end faces of the spinneret body 7. The cleaning assembly 20 fits against the discharge end of the spinneret body 7, where dirt accumulates and is stubborn. The air jet assembly 19 fits against the feed end of the spinneret body 7, where dirt accumulates less. As the first slide plate 17 and the second slide plate 18 move closer to each other, the square insert rod 21 is further inserted into the square tube 23. The drive motor 30 is started, which drives the drive gear 31 to rotate. The drive gear 31 meshes with the driven gear 32, driving the driven gear 32 to rotate. The driven gear 32 then drives the drive rod 33 to rotate. The drive rod 33 drives the square cylinder 23 to rotate via the second transmission belt 24. Simultaneously, the square cylinder 23 drives the square insert rod 21 inserted inside it to rotate synchronously. The square insert rod 21 then drives the rotating rod 36 to rotate via the first transmission belt 22. The rotating rod 36 ultimately drives the cleaning assembly 20 to rotate, thus achieving synchronous rotation of the air jet assembly 19 and the cleaning assembly 20. During the synchronous rotation of both, the inclined shovel 38 on the side of the cleaning assembly 20, due to its leading angle position, will first physically clean the discharge end plate surface of the spinneret body 7, loosening and removing the hardened carbonized residue on the plate surface. An external air source is connected to the air inlet 35 of the drive rod 33. The high-pressure airflow from the external air source enters the inner groove 34 of the jet assembly 19 through the air inlet 35. The pressure sensor in the inner groove 34 monitors the pressure data P in real time. The high-pressure airflow is ejected from the inner groove 34, impacting the micropores of the spinneret body 7. On the one hand, it blows away the residual moisture in the micropores, and on the other hand, it impacts and removes the blockages in the micropores. The high-pressure airflow passing through the micropores enters the air collection groove 39 of the cleaning assembly 20. The pressure sensor in the air collection groove 39 monitors the pressure data Q in real time. The airflow within the air chamber 39 is ultimately discharged to the outside of the equipment through the exhaust pipe 37. Operators can classify the state of the micro-orifices in the spinneret body 7 based on the pressure data P and Q monitored by the pressure sensors in the inner chamber 34 and the air collection chamber 39. When the micro-orifices are unobstructed, pressure data P is low and pressure data Q is high; when there is slight adsorption blockage, pressure data P is slightly high and pressure data Q is slightly low; when the micro-orifices are partially blocked, pressure data P is high and pressure data Q is low; when the micro-orifices are completely blocked, pressure data P is close to the pressure of the external air source and pressure data Q is close to zero. This method allows for precise marking and division of blocked areas on the spinneret body 7. Then, the drive motor 30 is stopped, allowing the jet assembly 19 to remain in the marked blocked area for an extended period, prolonging the impact time of the high-pressure airflow on the blocked micro-orifices. This achieves precise positioning and unblocking, ensuring effective unblocking while avoiding over-cleaning of unobstructed micro-orifices and reducing damage to the spinneret body 7.
