Description

Technical Field

[0001] The invention relates to the textile industry, and in particular to an air-spinning device and a system monitoring method. Background Art

[0002] As an industry with a long history, the textile industry has been pursuing technological innovation to improve production efficiency and product quality, while the demand for safety and reliability is also increasing. As an important equipment in the modern textile industry, the main function of the air-spinning device is to use the centrifugal force generated by the high-speed rotating vortex to tear the fiber bundle into single fibers and reassemble them into yarn. However, the existing air-spinning device has the following shortcomings in practical applications:

[0003] (1) Severe fiber damage: Due to the high surface roughness of the inner wall of the vortex tube and the yarn guide tube, the fiber is easily damaged during high-speed rotation and friction. This damage will not only reduce the strength and wear resistance of the yarn, but also affect the uniformity and appearance quality of the yarn.

[0004] (2) Insufficient component accuracy and stability: In existing devices, the processing accuracy of key components such as the air jet tube, cone and yarn guide tube is not high, which is prone to dimensional deviation and shape instability. This inaccuracy will lead to unstable vortex during air spinning, thus affecting the quality and production efficiency of the yarn.

[0005] (3) Difficult to clean and maintain. Fibers and dust easily accumulate in the vortex tube and the jet tube. If not cleaned in time, the equipment operation efficiency will decrease and the failure rate will increase. Most of the existing equipment relies on manual cleaning, which is time-consuming and labor-intensive, and cannot guarantee the thoroughness and timeliness of cleaning.

[0006] (4) Insufficient safety and reliability. Existing air-spinning devices operate under high temperature and high pressure, which are prone to equipment failure or damage, and may even lead to safety accidents in serious cases. In addition, there is a lack of effective monitoring and redundant control systems. When the main control system fails, the continuous operation and safe shutdown of the device cannot be guaranteed. Summary of the invention

[0007] The present invention provides an air-spinning device, which is provided with a guide body, a vortex tube, a conical body, a yarn guide tube and an air-spinning main control system. The vortex tube is connected with an air jet tube, which is used to spray high-pressure gas into the vortex tube. The vortex tube comprises a high-temperature resistant material layer and an outer explosion-proof shell covering the surface of the high-temperature resistant material layer. The inner walls of the vortex tube and the yarn guide tube are both provided with nano coatings.

[0010] The automatic cleaning system is used to regularly clean the inside of the vortex tube and the jet tube to prevent fiber and dust accumulation.

[0011] The redundant control module is connected with the temperature and pressure monitoring system and the air-spinning main control system. When the data of the temperature and pressure monitoring system and the air-spinning main control system are abnormal, the redundant control module takes over the air-spinning main control system.

The dust collection pipe is provided with a filter, and the dust collection unit and the jet cleaning unit operate synchronously;

[0026] The automatic detection unit is connected to the jet cleaning unit and the dust collection unit. The automatic detection unit is equipped with a cleanliness sensor for monitoring the cleanliness of the inner wall of the vortex tube and the jet tube. If the cleanliness sensor detects that the fiber and dust accumulation in the vortex tube and the jet tube exceeds the threshold, the automatic detection unit immediately triggers the jet cleaning unit and the dust collection unit. The cleanliness sensor includes a laser sensor and an infrared sensor.

[0037] The automatic cleaning system cleans the inner wall of the vortex tube and the jet tube, and automatically cleans the inner wall of the vortex tube and the jet tube according to the cleanliness of the inner wall;

[0038] The redundant control module is connected to the main control system of the air-spinning.

Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative labor.

[0047] Figure 1 The present invention is a simplified structural diagram of an air-spinning device.

[0048] Figure 2 It is a schematic diagram of the monitoring system of the air-jet spinning device of the present invention. DETAILED DESCRIPTION

[0049] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present invention. However, it is apparent to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features well known in the art are not described.

[0050] In order to fully understand the present invention, detailed steps and detailed structures will be proposed in the following description to illustrate the technical solution of the present invention. The preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other implementations.

[0051] Reference Figure 1 As shown, the present invention provides an air-spinning device, which is provided with a guide body 1, a vortex tube 3, a conical body 4, a yarn guide tube 5 and an air-spinning control system, and the vortex tube 3 is connected to an air jet tube 2, and the air jet tube 2 is used to spray high-pressure gas into the vortex tube 3. It should be noted that the structure of the air-spinning device does not involve the inventive point of the present invention, and the detailed structure is not repeated here.

[0052] In an optional embodiment, the guide body 1, the vortex tube 3, the cone body 4, and the yarn guide tube 5 can be integrally formed by 3D printing technology, and the material of each layer is manufactured layer by layer by 3D printing technology. When printing, the thickness and printing accuracy of each layer need to be accurately controlled to ensure that the shape and size of the structures such as the air jet tube 2, the cone body 4 and the yarn guide tube 5 meet the design requirements. Through the precise 3D printing process, the initial shape of the vortex tube 3 is formed, which provides a good foundation for subsequent hardening and processing.

[0053] (2) Based on the initial model completed by 3D printing, the parts are further processed using precision laser cutting technology. The laser cutting equipment uses a high-power fiber laser with a power range of 500 watts to 6000 watts, which can achieve micron-level cutting accuracy. The laser cutting parameters, including laser power, cutting speed, and focal position, are adjusted to ensure the final dimensional accuracy and shape stability of the air jet tube 2, the conical body 4, and the yarn guide tube 5.

[0054] (3) The vortex tube 3 or corresponding parts after laser cutting are surface treated, and ultrasonic cleaning is used to remove the tiny particles and impurities generated during the processing. The size and shape of the air jet tube 2, the cone body 4 and the yarn guide tube 5 are tested using high-precision measuring instruments to ensure that the diameter, tolerance and shape of each air jet tube 2, cone body 4 and yarn guide tube 5 meet the design requirements. If any deviation is found during the test, it is adjusted through a precision laser correction process to meet the design specifications.

[0055] (4) Assemble the vortex tube 3 or corresponding parts that have been processed and tested and qualified, and perform functional verification under a simulated working environment to ensure that the performance of the jet tube 2 is stable and reliable in actual work.

[0056] In an optional embodiment, the vortex tube 3 of the present invention is provided with a high temperature resistant material layer and an outer explosion-proof shell covering the surface of the high temperature resistant material layer. After the high temperature resistant material layer and the outer explosion-proof shell of the vortex tube 3 are formed separately by 3D printing process, the outer explosion-proof shell is installed on the surface of the high temperature resistant material layer. As an option, the high temperature resistant material layer and the outer explosion-proof shell can be tightly combined by high temperature sintering, adhesive coating bonding or mechanical pressing to prevent the two from falling off.

[0057] In an optional embodiment, nano coatings are provided on the inner walls of the vortex tube 3 and the yarn drawing tube 5. The nano coatings are treated to reduce the friction between the fiber and the inner walls of the vortex tube 3 and the yarn drawing tube 5, thereby reducing the damage to the fiber. The steps for preparing the nano coatings on the inner walls of the vortex tube 3 and the yarn drawing tube 5 are as follows:

[0058] (1) Chemical cleaning and ultrasonic cleaning are performed on the inner walls of the vortex tube 3 and the yarn drawing tube 5 to remove oil, oxides and other impurities to ensure that the inner wall surface is clean and pollution-free. The inner wall surface is further treated using plasma cleaning technology to increase the surface activity and improve the adhesion of the nano-coating. The outer shell of the vortex tube 3 is made of explosion-proof material to ensure strength. In order to achieve chemical cleaning and ultrasonic cleaning of the inner walls of the vortex tube 3 and the yarn drawing tube 5, the following steps can be taken: 1) Chemical cleaning: A cleaning agent (such as a degreasing agent or an acidic solution) can be injected into the vortex tube 3 and the yarn drawing tube 5 to ensure that the cleaning agent fully contacts the inner wall to remove oil, oxides and other impurities. 2) Ultrasonic cleaning: After chemical cleaning, the vortex tube 3 and the yarn drawing tube 5 are placed in an ultrasonic cleaning tank to further remove residual contaminants on the inner wall surface using the vibration effect of ultrasound. Ultrasonic cleaning is usually more thorough and helps to achieve a clean inner wall state.

[0059] (2) Select a composite coating material containing high-hardness nanoparticles, such as a mixture of nano-tungsten carbide and nano-titanium dioxide, with a particle size between 10-50 nanometers. Use an electrophoretic deposition process to deposit nano-coatings on the inner walls of the vortex tube 3 and the yarn drawing tube 5. Immerse the vortex tube 3 in a nano suspension and apply a uniform electric field to uniformly deposit the nanoparticles on the inner wall surface. Control the voltage and time of the electrophoretic deposition to ensure that the thickness of the coating is between 50-100 nanometers and uniformly covers the entire inner wall surface. In order to ensure that the nanolayer is only attached to the inner wall, the following methods are used: 1) Local coating technology: Before the nano coating is deposited, a masking material (such as a special tape or coating film) can be used to cover the outer surface, exposing only the inner wall area to prevent the nanoparticles from adhering to the outer surface. 2) Electrophoretic deposition process: When performing electrophoretic deposition, ensure that the vortex tube 3 and the yarn drawing tube 5 are immersed in the nano suspension, and apply a uniform electric field at the same time, so that the nanoparticles are mainly deposited in the inner wall area, and the outer surface is not coated because it does not contact the suspension. 3) Post-treatment: After coating, the outer surface is cleaned to remove the nanoparticles that may be attached, thereby further ensuring the cleanliness of the outer surface.

[0060] (3) The coated vortex tube 3 and the yarn drawing tube 5 are dried at low temperature to remove the solvent in the solution and preliminarily solidify the nano coating. The vortex tube 3 and the yarn drawing tube 5 are placed in a vacuum sintering furnace and sintered at high temperature in an argon protection environment at a temperature of 800-1000° C. for 1-2 hours to fully combine the nano coating with the inner wall and form a dense protective layer.

[0061] (4) The inner walls of the sintered vortex tube 3 and the yarn guide tube 5 are finely polished using nano-grinding technology to obtain an excellent mirror effect and significantly reduce the friction between the fiber and the inner wall. The surface is moderately roughened or pre-treated to ensure that the coating can adhere firmly. Subsequently, the inner wall is hardened using plasma spraying technology to enhance the adhesion of the nano-coating and improve its wear resistance and corrosion resistance, thereby ensuring long-term stable performance.

[0062] The vortex tube 3 is an important structure of the air-spinning device of the present invention, and its structure is specially designed. The vortex tube 3 of the present invention is provided with a three-layer protective structure including an outer explosion-proof shell, a middle high-temperature resistant material layer, and an inner corrosion-resistant nano-coating. The nano-coating is attached to the inner wall surface of the middle high-temperature resistant material layer. The outer explosion-proof shell and the middle high-temperature resistant material layer are tightly combined by using efficient bonding technology to ensure the integrity and stability of the multi-layer protective structure. The bonding technology can include high-temperature sintering, adhesive coating bonding or mechanical pressing methods to ensure that each layer of material does not delaminate or peel off under high temperature and high pressure environment. The three-layer protective structure is as follows:

[0063] (1) Outer explosion-proof shell: The outer layer of the vortex tube 3 is made of explosion-proof material to improve strength and impact resistance and prevent bursting caused by high pressure or accidental impact. The material of the explosion-proof shell can be selected from ASTM A572 high-strength alloy or carbon fiber composite material, which has excellent impact resistance and durability.

[0064] (2) Middle layer of high temperature resistant material: The middle layer of the vortex tube 3 is made of high temperature resistant material to resist high temperature environment and ensure the stability and safety of the vortex tube 3 under high temperature operation conditions. The middle layer material can be made of ceramic fiber composite material or high temperature resistant alloy material, which has excellent thermal stability and heat resistance.

[0065] (3) Inner corrosion-resistant nano-coating: The inner layer of the vortex tube 3 is treated with a corrosion-resistant nano-coating to prevent chemical corrosion and physical wear, thereby improving the service life and performance stability of the vortex tube 3. The coating thickness is controlled at a submicron level to ensure coating uniformity and adhesion, while not affecting the inner diameter and fluid dynamics of the vortex tube 3.

[0066] In addition, the air spinning device of the present invention also includes a temperature and pressure monitoring system, an automatic cleaning system and a redundant control module to improve safety and reliability. Figure 2 As shown, the specific composition and principle of the temperature and pressure monitoring system, automatic cleaning system and redundant control module are further explained below.

[0067] Temperature and pressure monitoring system

[0068] The temperature and pressure monitoring system consists of a temperature monitoring system and a pressure monitoring system.

[0069] Embodiment 1

[0070] In the first embodiment, both the temperature monitoring system and the pressure monitoring system are provided with a sensor module, a central control unit, an alarm unit, a sensor data recording unit, and a system self-checking and maintenance unit.

[0071] The sensor module of the temperature monitoring system includes multiple temperature sensors 7 installed at different parts of the air-jet spinning device, and the sensor module of the pressure monitoring system includes multiple pressure sensors 6 installed in the vortex tube 3. The temperature sensor or pressure sensor transmits the collected temperature data and pressure data to the central control unit.

[0072] The central control unit receives and processes real-time pressure or temperature data from the pressure sensor or each temperature sensor, determines whether the temperature or pressure of any part is within a safe range, and activates the alarm unit based on the pre-set safety pressure or temperature thresholds of each part when it detects that the pressure or temperature threshold of any part exceeds the set safety threshold.

[0073] The alarm unit includes an audible and visual alarm and an information push module, and the information push module is used to push the alarm information to the air spinning control system.

[0074] The sensor data recording unit is connected to the temperature sensor module, the pressure sensor module, and the alarm unit. The sensor data recording unit is used to record the temperature data of each temperature sensor, the pressure data of each pressure sensor, the alarm record of the alarm unit in real time, and generate a pressure monitoring log.

[0075] The system self-check and maintenance unit is used to perform regular self-checks on the sensor module, central control unit, alarm unit, and sensor data recording unit.

[0076] Embodiment 2

[0077] In the second embodiment, the temperature and pressure monitoring system includes a temperature sensor module, a pressure sensor module, a central control unit, an alarm unit, a sensor data recording unit, and a system self-checking and maintenance unit. The temperature sensor module and the pressure sensor module share a set of central control unit, alarm unit, sensor data recording unit, system self-checking and maintenance unit, which simplifies the system.

[0078] Automatic cleaning system

[0079] The automatic cleaning system 9 can regularly clean the vortex tube 3 and the jet hole to prevent fiber and dust accumulation, thereby reducing the failure rate and improving the operational reliability. In the present invention, the automatic cleaning system 9 includes a jet cleaning unit, a dust collection unit, a cleaning time control unit, an automatic detection unit and a cleaning data recording unit.

[0080] A cleaning time control unit is connected to the jet cleaning unit and the dust collection unit and is used for timingly triggering the jet cleaning unit and the dust collection unit.

[0081] The jet cleaning unit is equipped with a nozzle, one end of which is connected to the vortex tube 3 and / or the jet tube 2, and the other end is connected to the high-pressure air pump. The dust suction unit is equipped with a dust suction pipe, one end of which is connected to the vortex tube 3 and / or the jet tube 2, and the other end is connected to the negative pressure device. The dust suction pipe is provided with a filter, and the dust suction unit and the jet cleaning unit operate synchronously.

[0082] The automatic detection unit is connected to the jet cleaning unit and the dust collection unit. The automatic detection unit is equipped with a cleanliness sensor for detecting the cleanliness of the inner wall of the vortex tube 3 and the inner wall of the jet tube 2. If the cleanliness sensor detects that the fiber and dust accumulation in the vortex tube 3 and the jet tube 2 exceeds the threshold, the automatic detection unit immediately triggers the jet cleaning unit and the dust collection unit. In an optional embodiment, a laser sensor and an infrared sensor are selected to detect the cleanliness of the vortex tube 3 and the jet tube 2. In one embodiment, the cleanliness sensor can be directly built into the vortex tube 3 and the jet tube 2 for detection. In another embodiment, the cleanliness sensor is set outside the vortex tube 3 and the jet tube 2. When it is necessary to stop the machine for inspection, the cleanliness sensor can be sent into the vortex tube 3 and the jet tube 2 for detection by a robotic arm.

[0083] The cleaning data recording unit is used to record the time, duration and effect of each cleaning operation and generate a cleaning log.

[0084] The cleaning data recording unit of the automatic cleaning system 9 and the sensor data recording unit of the temperature and pressure monitoring system are configured in a hybrid solution. The shared components are core data (such as equipment operating status, key fault information), which are processed by a centralized data recording unit to ensure that the data of each system can be uniformly stored and managed, thereby improving the overall reliability and fault tolerance of the system. The non-shared components are other non-critical data (such as detailed operating parameters of each system), which are independently configured by each system and processed through their respective recording units. Specifically, the independent data recording unit of the cleaning data recording unit is used to record parameters such as cleaning time and effect; the sensor data recording unit of the temperature monitoring system records temperature data and alarm records; the sensor data recording unit of the pressure monitoring system records pressure data and alarm records. This hybrid configuration scheme optimizes the data processing process, ensuring that the system can effectively reduce costs while ensuring efficient operation.

[0085] Redundant control modules

[0086] When the main control system fails, the redundant control module 8 can immediately take over the control to ensure the continuous operation and safe shutdown of the device. The redundant control module 8 includes the following components.

[0087] 1) Fault detection and redundancy control unit. The fault detection and redundancy control unit is provided with a fault detection module and a redundant control module 8. The fault detection module is connected to the main air-spinning control system to detect whether the system is abnormal. If there is an abnormality, a fault signal is sent to the redundant control module 8. The redundant control module 8 takes over the main air-spinning control system and continues to operate according to preset logic and parameters;

[0088] 2) Safety shutdown and automatic recovery module. The safety shutdown and automatic recovery module is provided with a safety shutdown module and an automatic recovery module. After the redundant control module 8 takes over the control, the safety shutdown module determines whether a safety shutdown is required according to the operating status and executes it according to the preset program. If the operating parameters of the air-spinning main control system return to normal, the automatic recovery module transfers the control right of the redundant control module 8 back to the air-spinning main control system;

[0089] 3) Data synchronization and backup module. The data synchronization and backup module is provided with a data synchronization module and a data backup module. The data backup module is used to regularly back up the operating parameter data and logs of the main control system of air-jet spinning, which are promptly synchronized to the redundant control module 8 by the data synchronization module. When the redundant control module 8 takes over the control, it takes over the control with the operating parameters of the most recent normal operation of the system.

[0090] The above-mentioned automatic cleaning system 9, temperature monitoring system and pressure monitoring system are configured in a hybrid solution. The shared components are core data (such as equipment operating status, key fault information), which are processed by a centralized data recording unit to ensure that the data of each system can be uniformly stored and managed, thereby improving the overall reliability and fault tolerance of the system. Non-shared components are other non-critical data (such as detailed operating parameters of each system), which are independently configured by each system and processed through their respective recording units. Specifically, the automatic cleaning system 9 will record parameters such as cleaning time and effect; the temperature monitoring system records temperature data and alarm records; and the pressure monitoring system records pressure data and alarm records. This configuration scheme optimizes the data processing process, ensuring that the system can effectively reduce costs while ensuring efficient operation.

[0091] The system monitoring method of the present invention ensures the safe operation of the overall air-spinning system through the coordinated work of various modules, as follows:

[0092] 1) The temperature and pressure data of key components are detected in real time through the temperature and pressure monitoring system, and the data is transmitted to the central control unit. The central control unit receives and processes the pressure or temperature data, determines whether the temperature or pressure of any part is within the safe range, and according to the pre-set safety pressure or temperature threshold of each part, when it is detected that the pressure or temperature threshold of any part exceeds the set safety threshold, the alarm unit is activated, the data recording unit records the temperature data, pressure data, alarm records, and generates a pressure monitoring log;

[0093] 2) The automatic cleaning system 9 uses a timing trigger principle to clean the inner walls of the vortex tube 3 and the jet tube 2 on the one hand, and uses sensors to check the cleanliness of the inner walls of the vortex tube 3 and the jet tube 2 on the other hand. When the fiber and dust accumulation in the vortex tube 3 and the jet tube exceeds the threshold, the jet cleaning unit and the dust collection unit are immediately triggered to perform a cleaning procedure.

[0094] 3) When the operating data of the main control system of air-spinning (including but not limited to temperature, pressure, current, voltage, and speed) are abnormal, the redundant control module 8 will take over the main control system of air-spinning. When the redundant control module takes over the control, it will run with the operating parameters of the most recent normal operation of the main control system of air-spinning and take over the control. If the operating status is still abnormal after the redundant control module 8 takes over, the shutdown procedure will be executed immediately, and the machine will shut down slowly to avoid causing greater losses. When the data of the main control system of air-spinning returns to normal, the redundant control module 8 will transfer the control back to the main control system of air-spinning.
