Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of carbon fiber spinneret aperture detection, in particular to a separated high-performance carbon fiber spinneret aperture pressure deformation resistance device. BACKGROUND

[0002] As a key component in the production process of carbon fiber, the micron-level aperture size precision and structural stability of the carbon fiber spinneret directly determine the quality and performance of the final carbon fiber product. In actual production process, the spinneret is in an extreme working environment of high temperature and high pressure for a long time, and the aperture may be plastically deformed or damaged due to continuous pressure impact, resulting in uneven spinning, broken filament and a series of quality problems. Therefore, it is crucial to detect the pressure deformation resistance of the aperture under simulated working conditions before the spinneret leaves the factory or during its service life. However, the traditional detection methods have obvious limitations. First, many detection devices use fixed clamping structures, which are difficult to adapt to spinnerets of different sizes and thicknesses, have poor universality, and the replacement procedure of the detected parts is complicated, which seriously affects the detection efficiency. Second, the installation of sensors for monitoring key parameters such as pressure and deformation is often not stable enough, and may be displaced or loosened in a high-pressure environment, resulting in inaccurate data collection and affecting the reliability of the detection results. Third, the sealing performance of the detection cavity, especially the sealing design that can be self-adaptively enhanced under high pressure, is the core of ensuring stable pressure and simulating real working conditions, but the sealing structure of traditional devices is often simple and prone to leakage when the pressure rises. In addition, the entire detection process has low automation and strong dependence on manual operation, making it difficult to achieve fast, accurate and repeatable standardized detection.

[0034] 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.

[0035] This invention provides a technical solution: such as Figure 1 - Figure 8 The device shown is a split high-performance carbon fiber spinneret aperture pressure-resistant deformation device, including a detection tube 1 and a spinneret body 8 installed in the inner cavity of the detection tube 1. The top of the detection tube 1 is threaded with a top cover 2 for top sealing. The top of the inner cavity of the detection tube 1 is provided with a sensor assembly 5 for sensor installation by rotation clamping. The middle and lower part of the inner cavity of the detection tube 1 is provided with a clamping assembly 6 for fixing the spinneret body 8 by rotation. The bottom of the detection tube 1 is provided with an installation assembly 7 for sealing and supporting the bottom of the detection tube 1.

[0036] like Figure 3 , Figure 4 and Figure 5 As shown, the sensor assembly 5 includes an annular tube 501 disposed inside the detection tube 1. The annular tube 501 is clamp-shaped. An array of mounting blocks 502 are fixedly mounted on the outer side of the annular tube 501 and fixed to the inner wall of the detection tube 1. A mounting plate 511 is disposed in the middle of the inner cavity of the annular tube 501, and a recessed storage groove 512 is opened at the center of the top of the mounting plate 511. The smart sensor is installed by the mounting plate 511 in conjunction with the storage groove 512 opened at its top.

[0037] Furthermore, the inner side of the ring tube 501 is provided with a triangular array of clamping plates 503, and the ring tube 501 is fitted with a transmission plate 507 through the clamping plates 503. The transmission plate 507 has a mounting groove 508 that extends through the outer side of the transmission plate 507 at one end near the ring tube 501. The transmission plate 507 is fixedly mounted with a connecting shaft 509 through the mounting groove 508. The other end of the transmission plate 507 has an inwardly extending placement groove 510. The transmission plate 507 is fitted with the mounting plate 511 through the placement groove 510. The placement groove 510 at one end of the transmission plate 507 facilitates the snap-fit ​​installation of the mounting plate 511, thereby facilitating the replacement and maintenance of the mounting plate 511 and the replacement of the smart sensor mounted on the top of the mounting plate 511 through the storage groove 512.

[0038] Furthermore, the three sets of transmission plates 507 are fitted with rotating ring plates 504 through mounting grooves 508, and the middle part of the rotating ring plates 504 is provided with arc-shaped grooves 505 in a triangular array. The arc-shaped grooves 505 are inclinedly distributed. The rotating ring plates 504 are sleeved with connecting shafts 509 through the arc-shaped grooves 505. The outer side of the rotating ring plates 504 is partially fitted with teeth 506. The teeth 506 are located at the opening of the ring tube 501. The opening of the ring tube 501 is fitted with a worm gear 513. One end of the worm gear 513 is fixedly installed with a servo motor 514, and the servo motor 514 is fixedly connected to the outer side of the detection tube 1.

[0039] In use, the servo motor 514, in conjunction with the worm gear 513 fixedly installed at its output end, drives the meshing teeth 506 to rotate, thereby pushing the rotating ring plate 504 to rotate. At this time, the arc-shaped groove 505 arrayed in the middle of the rotating ring plate 504 pushes the connecting shaft 509 to shift, thereby driving the transmission plate 507 to move through the connecting shaft 509. Then, the mounting plate 511 is clamped and installed through the placement groove 510 opened at one end of the transmission plate 507, which facilitates the fixing of the smart sensor installed inside the storage groove 512 on its top. The reverse operation can replace the smart sensor.

[0040] like Figure 6 As shown, the clamping assembly 6 includes a mounting ring plate 606 fixedly installed in the middle of the inner cavity of the detection tube 1. The top of the mounting ring plate 606 is equipped with connecting blocks 607 arranged in a triangular array. The top of the connecting blocks 607 is rotatably sleeved with an inclined rotating block 608. The inner side of the rotating block 608 is rotatably sleeved with an inclined transmission block 609. The top of the inner side of the rotating block 608 is provided with an inwardly recessed snap-fit ​​groove 610. The snap-fit ​​groove 610 is used to clamp spinneret bodies 8 of different thicknesses.

[0041] Furthermore, the other end of the three sets of transmission blocks 609 is rotatably sleeved with a connecting sleeve shaft 605, and the mounting ring plate 606 is sleeved with the connecting sleeve shaft 605. The transmission shaft 602 is sleeved inside the connecting sleeve shaft 605.

[0042] Furthermore, a mounting sleeve 603 is provided below the connecting sleeve 605, and the mounting sleeve 603 is sleeved on the outside of the transmission shaft 602. A return spring 604 is fixedly installed on the top of the mounting sleeve 603, and the return spring 604 is sleeved on the outside of the transmission shaft 602. The top of the return spring 604 is connected to the bottom of the connecting sleeve 605. The transmission shaft 602 extends through the mounting assembly 7 to its bottom, and a cylinder 601 is fixedly installed on the bottom of the transmission shaft 602. The return spring 604 facilitates buffering during clamping and avoids high pressure affecting the detection.

[0043] The cylinder 601 drives the transmission shaft 602 fixedly installed at its output end and the mounting sleeve shaft 603 fixedly sleeved on its outer side to move upward. This causes the return spring 604 installed on its top to retract and simultaneously push the connecting sleeve shaft 605 upward. Then, the upward-moving connecting sleeve shaft 605 pushes the transmission block 609 rotatedly sleeved on its outer side to tilt. In turn, the transmission block 609 pushes the rotating block 608 rotatedly sleeved with it to tilt. Then, the three sets of rotating blocks 608 and the snap-fit ​​grooves 610 opened on their inner sides can quickly clamp the spinneret body 8 of different sizes. Conversely, it can be quickly disassembled and replaced.

[0044] like Figure 7 and Figure 8 As shown, the mounting assembly 7 includes a base plate 703 located at the bottom of the inner cavity of the detection tube 1, and the outer side of the base plate 703 is provided with threaded grooves 704. Bolts 708 are installed on the outer side of the detection tube 1, the bolts 708 penetrate the side wall of the detection tube 1 and are threadedly connected to the threaded grooves 704. Support rods 705 are installed on the top of the base plate 703, and a pad 706 is fixedly sleeved on the outer side of the support rod 705. An arc-shaped ring plate 707 is provided on the top of the pad 706, and the bottom of the arc-shaped ring plate 707 is fixedly connected to the bottom of the support rod 705. Sealing rubber is pre-set on both the inner and outer sides of the arc-shaped ring plate 707.

[0045] Furthermore, an arc-shaped mounting bracket 702 is installed on the bottom array of the base plate 703, and the other side of the mounting bracket 702 is fixedly connected to the outer side of the cylinder 601. An inclined support bracket 701 is fixedly installed on the outer side of the mounting bracket 702.

[0046] In use, the mounting assembly 7 is installed inside the detection tube 1 using bolts 708, and the cylinder 601 and clamping assembly 6 are installed using mounting bracket 702. After the installation of the intelligent sensor and spinneret body 8 is completed, the connection between the inner and outer sides of the pad 706 is sealed by the preset arc-shaped ring plate 707 and the sealing rubber on its inner and outer sides, thereby sealing the bottom of the inner cavity of the detection tube 1. At the same time, as the pressure in the inner cavity of the detection tube 1 continues to increase, the arc-shaped ring plate 707 can be bent, thereby pressing the inner and outer sides of the arc-shaped ring plate 707 against the joint between the inner and outer sides of the pad 706, thereby increasing the degree of sealing.

[0047] like Figure 2 As shown, an air pump 3 is fixedly installed on the top of the top cover 2. The output end of the air pump 3 is connected to an air pipe 4. The air pipe 4 extends through the top cover 2 to the inside of the detection tube 1. The air pump 3 and the air pipe 4 facilitate pressurization of the inside of the detection tube 1, thereby simulating the working environment of the spinneret body 8 under high pressure, and then performing pressure resistance testing on its aperture.

[0048] Working principle: First, the spinneret body 8 to be tested is placed in the lower middle of the inner cavity of the detection tube 1 at a predetermined position; then, the cylinder 601 inside the clamping assembly 6 is activated; the cylinder 601 drives the transmission shaft 602 to move upward, causing the mounting sleeve shaft 603 sleeved on its outer side to move upward synchronously, and compressing the return spring 604 sleeved on the transmission shaft 602; this action further pushes the connecting sleeve shaft 605 connected to the top of the return spring 604 to move upward; the upward movement of the connecting sleeve shaft 605 forces its three sets of The rotating transmission block 609 tilts, which in turn pushes the hinged rotating block 608 to rotate around the connecting block 607. This causes the locking grooves 610 on the inner side of the three sets of rotating blocks 608 to clamp the outer edge of the spinneret body 8 evenly and stably in the circumferential direction. The return spring 604 not only provides the necessary preload but also acts as a highly efficient buffer mechanism to absorb overload energy when the system pressure fluctuates, effectively preventing clamping damage to the precision spinneret caused by rigid impact.

[0049] While fixing the spinneret body 8, the sensor module is installed; the intelligent sensor (including pressure and deformation sensors) is precisely placed in the storage slot 512 on the top of the mounting plate 511 of the sensor assembly 5; by starting the servo motor 514, the worm 513 at its output end is driven to rotate, and the worm 513 meshes with the teeth 506 on the outer side of the rotating ring plate 504, causing the rotating ring plate 504 to rotate; the triangular array and inclined distribution of the arc-shaped grooves 505 on the rotating ring plate 504 pushes the connecting shaft 509 sleeved with it to generate displacement during rotation, and the connecting shaft 509 drives the three sets of transmission plates 507 to move synchronously; the transmission plate 507 is sleeved with the mounting plate 511 through the placement slot 510 at its end, thereby uniformly transmitting the clamping force and realizing the firm locking of the mounting plate 511 and the intelligent sensor above it.

[0050] Finally, the bottom of the test tube 1 is sealed and supported by the installation component 7; the base plate 703 is placed into the bottom of the test tube 1, and the arrayed bolts 708 are used to penetrate the tube wall and screw into the threaded grooves 704 on the side of the base plate 703 to achieve initial fastening; the support rods 705 and the pads 706 on the base plate 703 constitute a load-bearing structure.

[0051] Once all components are installed, the top cover 2, which includes the air pump 3 and air pipe 4, is screwed onto the top of the detection tube 1 via a threaded connection to form an upper seal. At this point, the inner cavity of the detection tube 1 becomes a closed pressure vessel. The air pump 3 is started, and compressed gas is continuously injected into the sealed cavity through the air pipe 4. The internal pressure steadily increases, accurately simulating the high-pressure working environment that the carbon fiber spinneret experiences during the actual spinning process.

[0052] Under continuous and stable high pressure, the micron-sized pores of the spinneret body 8 will withstand enormous fluid pressure. During this stage, the intelligent pressure and deformation sensors, which are firmly clamped on the mounting plate 511, begin to play a key role, monitoring and collecting key parameter data such as pressure changes in the cavity and possible microscopic deformations of the spinneret in real time and with high precision. These data are transmitted to an external analysis system to evaluate the pressure resistance and structural integrity of the spinneret pores. At the same time, as the pressure inside the cavity continues to rise, the pressure on the arc-shaped ring plate 707 in the mounting assembly 7 also increases, resulting in downward elastic bending deformation. This deformation causes the sealing rubber on its inner and outer sides to be pressed more tightly against the mating surface of the pad 706, forming an adaptive and self-reinforcing sealing effect of "the higher the pressure, the tighter the seal," ensuring no leakage during the entire high-pressure maintenance stage and greatly improving the reliability and authenticity of the detection.

[0053] After the testing task is completed, first turn off the air pump 3 and slowly release the residual pressure in the test tube 1; then, reverse control cylinder 601 and servo motor 514 drive clamping assembly 6 and sensor assembly 5 to release the lock on spinneret body 8 and mounting plate 511 in sequence; the operator can then safely and conveniently remove the spinneret sample and smart sensor to complete the entire testing process.

[0054] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0055] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
