Description
The application is application number: 201810210613.6, filing date: 2018-03-14, entitled "functional coating fabric precision coating and scraping mechanism".
Technical Field
The invention relates to a coating fabric coating and scraping mechanism.
Background
The functional coated fabric is a product which is formed by uniformly coating one (or more) layers of high molecular compounds on the surface of fabric and forming one or more layers of films on the surface of the fabric through adhesion so as to endow the fabric with specific functions of water and oil repellency, flame retardance, antibiosis, radiation protection, static resistance and the like, wherein the used film-forming high polymer is called a coating agent, and the used fabric is called a base fabric. The fabric can meet the requirement of modern society on high functionalization of textiles, and is widely applied to the fields of industry, military, disaster relief, daily life, medical care, special protection, field operation and the like. Compared with the common printing and dyeing finishing technology, the functional coating fabric has certain special functions while endowing the fabric with unique style, hand feeling and appearance, thereby greatly improving the added value of the product and having better market demand.
In order to obtain the functional coating fabric with stable quality and excellent performance, an advanced coating processing technology and high-performance processing equipment play a decisive role in the quality of products besides selecting a high-quality and proper coating agent. The coating method of the fabric is various, including direct coating, transfer coating, setting coating, foam coating, lamination and the like, wherein the direct coating is widely applied due to the simplicity of the coating process and equipment, and the method mainly comprises the steps of uniformly coating the coating agent on the fabric by using an applicator, and then drying to volatilize the solvent or moisture, so that the coating agent forms a continuous and tough film on the surface of the fabric, thereby preparing the functional coated fabric meeting the use requirement. With the continuous development of social economy, people have higher and higher performance requirements on the functional coating fabric, which promotes the development of the production technology of the functional coating fabric, particularly the precision of production equipment. The coating and scraping system of the coating agent is one of important functional components in direct coating equipment, and is required to be capable of accurately, uniformly, continuously and stably coating the coating agent on the surface of a fabric, while the traditional coating and scraping system does not have the function of self-adaptive adjustment of the height of a scraper, and deviates from a balance position when being subjected to external disturbance force, so that the coating amount of the coating agent on the fabric deviates from a theoretical value, the product quality is unstable, and the production efficiency is reduced. Therefore, if modern mechanical design theory and control technology can be applied to a traditional direct coating scraping system, the self-adaptive adjustment function of the height of the scraper in the working process is realized, the scraper can be quickly restored to a balance position when being disturbed by the outside, and the coating precision and the uniform stability of the coating agent on the fabric are ensured.
The giant magnetostrictive material is a novel smart material developed in recent years, and has the excellent characteristics of large strain, strong force, high electromechanical coupling coefficient, quick response and the like. The giant magnetostrictive actuator based on the magnetostrictive effect has wide application prospect, can be widely applied to the fields of precise positioning, ultra-precision machining, micromotor robots, vibration and noise reduction, sonar, micro-electro-mechanical systems and the like, is a potential novel actuator, receives attention of developed countries and regions in the U.S., Japan, Europe and the like, and has made important progress in the aspects of theoretical models, dynamic and static characteristics, development and application of new devices and the like. The piezomagnetic sensor is a new type of sensor emerging at home and abroad in recent years, and the action principle is based on the magnetoelastic effect, namely when a ferromagnetic material receives the action of mechanical force, strain is generated in the ferromagnetic material, so that stress is generated, and the magnetic conductivity is changed. The sensor converts the acting force into the change of the sensor magnetic permeability and outputs an electric signal with corresponding change through the change of the magnetic permeability, and has the advantages of large output power, strong signal, simple structure, superior anti-interference performance, strong overload capacity, simple manufacturing process and the like. Compared with a piezoelectric sensor, the piezoelectric sensor has the advantages of simple signal amplification circuit, no need of a charge amplifier and a special coaxial cable and the like; compared with a resistance strain sensor, the sensor has the advantages of no need of adhesion, simple installation method and the like. Therefore, the giant magnetostrictive material and the piezomagnetic sensor are combined and applied to a coating and scraping system of functional coated fabric, the position height of the scraper can be adjusted in real time according to a detection signal of the piezomagnetic sensor to the actual working position of the scraper so as to ensure that the scraper is always in an ideal balance position, and the precise coating of slurry by the scraper is realized.
At present, the research on a precision coating and scraping mechanism of functional coated fabrics is less, and particularly, the research on the self-adaptive adjustment of the height of a scraper is realized by combining a giant magnetostrictive driver and a piezomagnetic sensor. For example, patent document 201320543700.6 by scholar et al proposes a high-precision kiss coater, which is mainly provided with a precision scraping device and a vacuum adsorption device at the rear of an anilox roller, wherein the precision scraping device is provided with a precision scraper bar which is supported by a roller bracket, the roller bracket is connected with a return pipe, a bracket flow guide opening is arranged at a position where the precision scraper bar is tangent to the roller bracket, the precision scraping device is provided with a lifting device, and the lifting device is connected with a precision guide roller. From the description, it is clear that this patent does not use a giant magnetostrictive material and a piezomagnetic sensor, let alone that the combination of both allows a real-time adjustment of the height of the doctor blade to ensure a precise application of the coating agent on the fabric.
Royal courage et al in patent 200910144074.1 propose a combination device for improving the working accuracy of a comma scraper, which is capable of accurately and rapidly adjusting the tightening torque of nuts at both ends of an auxiliary shaft according to the gravity and the working load applied to the scraper to generate a predetermined axial load, and applying a required torque to the comma scraper to ensure that the straightness of the edge of the high-precision scraper can be maintained at a high working accuracy in a working state. From the description, it is clear that this patent does not use a giant magnetostrictive material and a piezomagnetic sensor, let alone that the combination of both allows a real-time adjustment of the height of the doctor blade to ensure a precise application of the coating agent on the fabric.
Jinguohua in patent document 201320161634.6 proposes a novel high-precision MG coating unit, which can make the coating amount of the whole film surface of the substrate uniform, is easy to control, has high coating precision, is not easy to generate glue drawing on the film surface, and improves the qualified rate of coating film. From the description, it is clear that this patent does not use a giant magnetostrictive material and a piezomagnetic sensor, let alone that the combination of both allows a real-time adjustment of the height of the doctor blade to ensure a precise application of the coating agent on the fabric.
In conclusion, no patent application related to a precise coating and scraping mechanism of the functional coated fabric is found at present.

When the giant magnetostrictive actuator works, the alternating current coil 3 and the direct current coil permanent magnet 4 generate heat, so that the working temperature of the giant magnetostrictive rod 7 is increased, the expansion performance of the giant magnetostrictive rod is greatly influenced by the working temperature, therefore, in order to ensure that the giant magnetostrictive rod is always in a normal working state when working, a cooling system is required to be arranged in the giant magnetostrictive actuator, the coil framework 5 is set to be a hollow structure, cooling grooves for cooling liquid to flow are formed in the lower end cover 2 and the outer sleeve 6, the cooling grooves are connected with the coil framework 5, so that the cooling liquid flows in from the cooling grooves in the lower end cover 2, flows out from the cooling grooves in the outer sleeve 6 after flowing through the wire coil framework 5, and the circulating flow of the cooling liquid is realized. Meanwhile, in order to ensure that the working temperature of the giant magnetostrictive rod is constant, a magnetic pump and an electric regulating valve are installed on a flow channel of the cooling liquid, and the magnetic pump and the electric regulating valve can regulate the flow speed and the flow of the cooling liquid according to a feedback signal of a temperature sensor 19 installed on the giant magnetostrictive rod 7. When the temperature sensor 19 detects that the working temperature of the giant magnetostrictive rod 7 rises, after the working temperature is identified and processed by the controller, the controller sends an instruction to the magnetic pump and the electric regulating valve, so that the flow speed and the flow of the cooling liquid in the cooling tank are increased, the heat dissipation speed of the alternating current coil 3 and the direct current coil permanent magnet 4 is increased, after the temperature sensor 19 detects that the working temperature of the giant magnetostrictive rod 7 falls, the controller sends an instruction to the magnetic pump and the electric regulating valve, and the flow speed and the flow of the cooling liquid in the cooling tank are gradually reduced.
Because the tensile strength of the giant magnetostrictive rod is low, the giant magnetostrictive rod must work under a stressed condition, and the appropriate pre-pressure can increase the magnetostrictive amount of the giant magnetostrictive rod. Therefore, in the invention, the magnetostrictive rod 7 is in a compressed state through the combined action of the locking nut 11, the pre-pressing spring 9, the output rod 8 and the lower end cover 2, and the giant magnetostrictive rod 7 is still in the compressed state when the upper surface of the stop block 25 is in contact with the protection block 26.
The present invention will be described in detail below with reference to the accompanying drawings, taking one working cycle as an example:
before working, the balance position of the scraper 18 is firstly determined according to the production process requirement, then the giant magnetostrictive rod 7 is in a compressed state under the action of the locking nut 11 and the pre-pressing spring 9, the lower surface of the stop block 25 is in contact with the protection block 26, and then the bias current I is introduced into the alternating current coil 3 and the direct current coil permanent magnet 4, so that the giant magnetostrictive rod 7 generates a certain elongation to drive the scraper 18 to rise to the balance position along the vertical upward direction, namely the elongation enables the scraper connecting frame 14 to be just in contact with the steel ball 21 in the two piezomagnetic pressure sensors without generating pressure. At the same time, the cooling system is started and the cooling liquid circulates in the coil bobbin 5.
When the pressure sensor works, if the scraper 18 does not have any disturbing force in the vertical direction, the scraper connecting frame 14 does not generate any pressure on the two piezomagnetic pressure sensors, and the current in the alternating current coil 3 and the direct current coil permanent magnet 4 is not changed; if the scraper 18 is subjected to a downward disturbing force in the vertical direction, the giant magnetostrictive rod 7 is shortened, the scraper connecting frame 14 generates pressure on the piezomagnetic pressure sensor positioned below the scraper connecting frame, so that the piezomagnetic pressure sensor generates induced potential, the signal is processed by the controller, and then a control current ic1 is sent to the alternating current coil 3 and the direct current coil permanent magnet 4, so that the electrifying currents of the two are increased, the giant magnetostrictive rod 7 is extended until the pressure generated by the scraper connecting frame 14 on the two piezomagnetic pressure sensors is zero, namely the scraper 18 is restored to a balance position; if the scraper 18 is subjected to an upward disturbing force in the vertical direction, the giant magnetostrictive rod 7 extends, the scraper connecting frame 14 generates pressure on the piezomagnetic pressure sensor positioned above the scraper connecting frame to enable the piezomagnetic pressure sensor to generate induced potential, the signal is processed by the controller, and then a control current ic2 is sent to the alternating current coil 3 and the direct current coil permanent magnet 4 to reduce the electrifying current of the two, so that the giant magnetostrictive rod 7 contracts until the pressure generated by the scraper connecting frame 14 on the two piezomagnetic pressure sensors is zero, namely the scraper 18 is restored to the balance position. When the temperature sensor 19 detects that the working temperature of the giant magnetostrictive rod 7 is higher, the flow speed and the flow rate of the cooling liquid in the cooling tank are increased through the action of the cooling system controller on the magnetic pump and the electric regulating valve, the heat dissipation speed of the alternating current coil 3 and the direct current coil permanent magnet 4 is increased, and the working temperature of the giant magnetostrictive rod 7 is reduced to a normal value.
After the work is finished, the current in the alternating current coil 3 and the direct current coil permanent magnet 4 is gradually reduced, and the cooling system is closed.
