Description

Technical Field

[0001] The present invention relates to the field of fiberglass mesh cloth processing, and more specifically, to an automated coating device for fiberglass mesh cloth. Background Art

[0002] Fiberglass mesh cloth is made of fiberglass woven fabric as the base material and is treated by soaking and coating with a polymer emulsion. Fiberglass is an excellent inorganic non-metallic material with high strength, high modulus, high temperature resistance, corrosion resistance, insulation and other properties, and the mesh structure of the mesh cloth makes it have relatively uniform mechanical properties in all directions.

[0003] In the wall insulation system, it can enhance the mechanical strength of the insulation layer and prevent the insulation layer from cracking and falling off; in the interior and exterior wall plastering, it can improve the crack resistance and integrity of the plastering layer; in the roof waterproofing project, it can be used as a reinforcing material for waterproofing membranes to improve the tensile strength and puncture resistance of the waterproofing membranes.

[0004] The "Spraying Device and Process for Processing Fiberglass Alkali-Resistant Coated Mesh Cloth" disclosed in Chinese Invention Patent 202411673283.6 has a specification that discloses: including a horizontally arranged base, and an installation roller and a winding roller are provided above the base; when the mesh cloth contacts the detection structure, the mesh cloth is in extrusion contact with the extrusion ring, squeezing the first extrusion spring and driving the extrusion ring to move downward. When the extrusion ring moves downward, it squeezes the corresponding first extrusion telescopic rod, relies on the first joint to communicate with the fixed cylinder, drives the moving plate to move, the moving plate drives the first connecting rod and the second connecting rod to move synchronously. When the first connecting rod moves, it squeezes the sealing plate and drives the sealing plate to move, so that the opening is communicated with the liquid inlet channel. When the second connecting rod moves, it drives the baffle to move, so that the second air outlet hole corresponds to the first air outlet hole, so as to facilitate automatically adjusting the spraying range and the drying range according to the width of the mesh cloth; the above patent can prove the defects existing in the prior art. However, in the process of solving its defects, the above patent only solves the problems of adjusting the spraying range and the drying range, and does not deal with the influence of air bubbles and the angle of the scraper on the coating effect during the coating process.

[0005] During coating, when the angle between the scraper and the mesh cloth is small, the coating material flows slowly under the push of the scraper, resulting in a thinner coating thickness. At the same time, due to the weak extrusion effect of the scraper on the coating material, the combination between the material and the mesh cloth is not tight enough, and phenomena such as hollowing and delamination are likely to occur, affecting the coating effect;

[0006] When the angle between the scraper and the fiberglass mesh is too large, the shearing force of the scraper on the coating material will increase, resulting in uneven distribution of the coating material on the surface of the fiberglass mesh and inconsistent thickness. Moreover, an excessive angle may cause a large frictional force on the fiberglass mesh during the movement of the scraper, damaging the surface of the fiberglass mesh and affecting its mechanical properties;

[0007] In addition, during the coating process, if the coating speed is too fast, the air between the coating material and the fiberglass mesh will not have time to escape, thus forming bubbles. In addition, improper stirring method or stirring speed of the coating equipment may also entrain air into the coating material, generating a large number of bubbles.

[0008] Therefore, we made improvements and proposed an automatic coating equipment for fiberglass mesh. Summary of the Invention

[0045] As a preferred technical solution of the present application, an automatic coating dynamic adjustment system for fiberglass mesh cloth is characterized by including a detection unit, a control system, and an execution unit;

[0046] Thickness sensors: Usually, non-contact laser ranging sensors or capacitive sensors are used. The laser ranging sensor determines the distance between the surface of the mesh cloth and the sensor by emitting a laser beam and measuring the time of the reflected light, so as to accurately obtain the coating thickness information; the capacitive sensor utilizes the relationship between the capacitance and the distance between the plates to detect the position change of the surface of the mesh cloth, and thus obtains the coating thickness data. These sensors are distributed at different positions in the coating area to continuously monitor the coating thickness of the fiberglass mesh cloth and feed the data back to the control system.

[0047] Angle sensors: Rotary encoders or inclination sensors are adopted. The rotary encoder is installed on the rotating shaft of the scraper, and the actual angle of the scraper is accurately measured by recording the rotation angle of the rotating shaft; the inclination sensor can directly detect the inclination angle of the scraper relative to the horizontal plane. The angle sensor transmits the measured angle information to the control system in a timely manner for angle adjustment.

[0048] Control system

[0049] Data processing module: Receives data from the thickness sensor and the angle sensor, analyzes and processes it. Through specific algorithms, such as calculations based on mathematical models or machine learning algorithms, according to the preset coating thickness standard and the ideal scraper angle range, calculates the deviation between the current coating thickness and the target thickness, and the difference between the current scraper angle and the optimal angle.

[0050] Control algorithm module: According to the calculation results of the data processing module, combined with factors such as the running speed of the fiberglass mesh and the characteristics of the coating material, uses a dynamic adjustment algorithm to generate corresponding control instructions to achieve precise adjustment of the scraper angle and coating thickness.

[0051] Human-machine interaction interface: Operators can set the target value of the coating thickness, the initial value of the scraper angle, adjustment parameters, etc. through this interface. At the same time, this interface can also display information such as the current coating thickness, scraper angle, and system operating status in real time, facilitating operators to monitor and intervene in the system operation.

[0052] As a preferred technical solution of this application, the detection module:

[0053] Temperature sensor: Usually uses thermocouples or resistance temperature detectors, distributed at different positions in the air-drying area, such as the entrance, middle, and exit. Thermocouples are based on the thermoelectric effect, converting temperature changes into potential differences; resistance temperature detectors measure temperature based on the change characteristics of resistance with temperature. They continuously monitor the temperature of the mesh surface and the surrounding environment and transmit the data to the control module;

[0054] Humidity sensor: Mostly uses capacitive or resistive humidity sensors to monitor the humidity in the air-drying environment. Capacitive humidity sensors work based on the principle that the capacitance of the humidity-sensitive material changes with humidity; resistive humidity sensors utilize the characteristic that the resistance value of the humidity-sensitive resistor changes with humidity. Humidity data provides a reference for the control module to adjust temperature and time because humidity affects the water evaporation rate and thus the air-drying effect;

[0055] Wind speed sensor: Commonly used mechanical and ultrasonic wind speed sensors. Mechanical wind speed sensors drive the shaft to rotate through the rotation of the impeller, converting wind speed into an electrical signal; ultrasonic wind speed sensors measure wind speed based on the relationship between the propagation speed of ultrasonic waves in the air and wind speed. Wind speed data affects the heat transfer and water evaporation rate and is also an important basis for dynamic adjustment;

[0056] Control module:

[0057] Data processing unit: Receives data from temperature, humidity, and wind speed sensors, uses signal processing techniques such as filtering and amplification to remove noise interference and improve data accuracy. At the same time, compares and analyzes the processed data with the preset standard values;

[0058] Control algorithm unit: According to the analysis results of the data processing unit, algorithms such as PID control algorithm are adopted. Taking the PID algorithm as an example, by calculating the proportional, integral, and differential relationships between the actual value and the set value, the control parameters are dynamically adjusted, and control instructions are output to the execution module to achieve precise control of temperature and time;

[0059] Human-machine interaction interface: Operators can set parameters such as target temperature, humidity range, wind speed threshold, and air-drying time here, and can also view information such as the system operation status and historical data records in real time. In addition, when the system has an abnormality, fault diagnosis and parameter adjustment can be carried out through this interface.

[0060] Compared with the prior art, the beneficial effects of the present invention are:

[0061] In the solution of this application:

[0062] 1. When exhausting and adjusting the angle of the scraper, the hydraulic rod expands and contracts to drive the connecting plate to rise and fall. The rise and fall of the connecting plate drive the rise and fall of the toothed plate, and then drive the rotation of the gear. During the rotation of the gear, the rotating shaft and the scraper are driven to rotate, thereby realizing the adjustment of the scraper angle;

[0063] 2. When exhausting, the pressure roller descends. During the descending process, due to the elastic action of the spring rod, the roller shaft moves in the reverse direction, and then rises. At this time, the cloth is located between the roller shaft and the pressure roller. When coating, the roller shaft and the pressure roller squeeze the cloth so that the raw materials on its surface are squeezed to discharge the bubbles. Description of the drawings

[0123] An automatic coating dynamic adjustment system for fiberglass mesh cloth includes a detection unit, a control system, and an execution unit.

[0124] Thickness sensors: Usually, non-contact laser ranging sensors or capacitive sensors are used. The laser ranging sensor determines the distance between the surface of the mesh cloth and the sensor by emitting a laser beam and measuring the time of the reflected light, so as to accurately obtain the coating thickness information; the capacitive sensor uses the relationship between the capacitance and the distance between the plates to detect the position change of the surface of the mesh cloth, so as to obtain the coating thickness data. These sensors are distributed at different positions in the coating area to monitor the coating thickness of the fiberglass mesh cloth in real time and feed the data back to the control system.

[0125] Angle sensor: A rotary encoder or an inclination sensor is used. The rotary encoder is installed on the rotating shaft 103 of the squeegee 108. By recording the rotation angle of the rotating shaft 103, the actual angle of the squeegee 108 can be accurately measured; the inclination sensor can directly detect the inclination angle of the squeegee 108 relative to the horizontal plane. The angle sensor transmits the measured angle information to the control system in a timely manner for angle adjustment.

[0126] Control system

[0127] Data processing module: Receives data from the thickness sensor and the angle sensor, analyzes and processes it. Through specific algorithms, such as calculations based on mathematical models or machine learning algorithms, according to the preset coating thickness standard and the ideal angle range of the squeegee 108, calculates the deviation between the current coating thickness and the target thickness, and the difference between the current angle of the squeegee 108 and the optimal angle.

[0128] Control algorithm module: According to the calculation results of the data processing module, combined with factors such as the running speed of the fiberglass mesh cloth and the characteristics of the coating material such as viscosity and fluidity, uses dynamic adjustment algorithms such as the PID control algorithm to generate corresponding control instructions to achieve precise adjustment of the angle of the squeegee 108 and the coating thickness.

[0129] Human-machine interface: Operators can set the target value of the coating thickness, the initial value of the angle of the squeegee 108, adjustment parameters, etc. through this interface. At the same time, this interface can also display information such as the current coating thickness, the angle of the squeegee 108, and the system operation status in real time, facilitating operators to monitor and intervene in the system operation.

[0130] The thickness sensor continuously monitors the coating thickness of the fiberglass mesh cloth and transmits the data to the control system. When it detects a deviation between the coating thickness and the preset target thickness, the data processing module calculates the deviation value. The control algorithm module generates adjustment instructions using the control algorithm based on the deviation value and other relevant parameters such as the mesh cloth speed and material characteristics. This instruction is sent to the thickness adjustment mechanism to gradually make the coating thickness approach the target value by adjusting the gap between the squeegee 108 and the mesh cloth or the supply amount of the coating material. During the adjustment process, the thickness sensor continuously monitors the thickness change to form a closed-loop control to ensure the accuracy and stability of the coating thickness.

[0131] Dynamic Angle Adjustment of the Scraping Blade 108: The angle sensor measures the angle of the scraping blade 108 in real time and feeds the information back to the control system. The control system calculates the angle adjustment amount based on the difference between the current angle and the optimal angle determined according to coating process requirements and material properties, etc., through the control algorithm module, and issues a control command. After receiving the command, the angle adjustment mechanism of the scraping blade 108 adjusts the angle of the scraping blade 108 through the motor and transmission device, so that the scraping blade 108 maintains the optimal working angle, ensuring that the coating material can be evenly coated on the fiberglass mesh cloth and avoiding problems such as uneven thickness and bubbles. At the same time, the angle sensor continuously monitors the angle of the scraping blade 108 to achieve dynamic and precise control of the angle.

[0132] An automated coating dynamic adjustment system for fiberglass mesh cloth further includes

[0133] Detection module:

[0134] Temperature sensors: Usually thermocouples or resistance temperature detectors are used, distributed at different positions in the air-drying area, such as the entrance, middle, and exit. Thermocouples are based on the thermoelectric effect, converting temperature changes into potential differences; resistance temperature detectors measure temperature based on the characteristic that resistance changes with temperature. They monitor the temperature of the mesh surface and the surrounding environment in real time and transmit the data to the control module;

[0135] Humidity sensors: Mostly capacitive or resistive humidity sensors are used to monitor the humidity in the air-drying environment. Capacitive humidity sensors work based on the principle that the capacitance of the humidity-sensitive material changes with humidity; resistive humidity sensors utilize the characteristic that the resistance value of the humidity-sensitive resistor changes with humidity. The humidity data provides a reference for the control module to adjust temperature and time because humidity affects the water evaporation rate and thus the air-drying effect;

[0136] Wind speed sensors: Commonly used ones include mechanical types such as vane anemometers and ultrasonic wind speed sensors. Mechanical wind speed sensors drive the shaft to rotate through the rotation of the impeller, converting wind speed into an electrical signal; ultrasonic wind speed sensors measure wind speed based on the relationship between the propagation speed of ultrasonic waves in the air and wind speed. Wind speed data affects the heat transfer and water evaporation rate and is also an important basis for dynamic adjustment;

[0137] Control module:

[0138] Data processing unit: Receives data from temperature, humidity, and wind speed sensors, uses signal processing techniques such as filtering and amplification to remove noise interference and improve data accuracy. At the same time, compares and analyzes the processed data with preset standard values;

[0139] Control algorithm unit: According to the analysis results of the data processing unit, algorithms such as PID proportional-integral-derivative control algorithm are adopted. Taking the PID algorithm as an example, by calculating the proportional, integral, and derivative relationships between the actual value and the set value, the control parameters are dynamically adjusted, and control instructions are output to the execution module to achieve precise control of temperature and time;

[0140] Human-machine interaction interface: Operators can set parameters such as target temperature, humidity range, wind speed threshold, and air-drying time here, and can also view information such as the system operation status and historical data records in real time. In addition, when the system malfunctions, fault diagnosis and parameter adjustment can be carried out through this interface.

[0141] Initial stage: After the system is started, the detection module collects temperature, humidity, and wind speed data in real time. The control module calculates the initial heating power, ventilation volume, and moving speed of the fiberglass mesh cloth according to the preset parameters and algorithms, so that the system quickly reaches a state close to the target.

[0142] Operation stage: As the air-drying process progresses, the detection module continuously monitors various parameters. If the temperature is too high, the control module instructs the heating equipment to reduce the power; if the humidity is higher than the set range, on the one hand, the ventilation volume is increased to accelerate the discharge of moisture, and on the other hand, the temperature may be appropriately increased to accelerate evaporation; if the wind speed does not meet the requirements, the ventilation equipment is adjusted. At the same time, according to the moving speed of the fiberglass mesh cloth and the air-drying effect, the moving speed is dynamically adjusted to ensure an appropriate air-drying time.

[0143] End stage: When the detection module feedbacks that all parameters reach the preset end conditions, such as the temperature and humidity are stable within the target range and the set shortest air-drying time is reached, the control module instructs the execution module to stop heating, reduce the ventilation volume, and stop the transmission device to complete the current air-drying process.

[0144] The usage process of an automated coating device for fiberglass mesh cloth provided by the present invention is as follows:

[0145] When exhausting gas and adjusting the angle of the scraper 108, the hydraulic rod 302 expands and contracts to drive the connecting plate 105 to rise and fall. The rise and fall of the connecting plate 105 drives the rise and fall of the toothed plate 104, and then drives the rotation of the gear 102. During the rotation of the gear 102, the rotating shaft 103 and the scraper 108 are driven to rotate, thereby realizing the adjustment of the angle of the scraper 108;

[0146] When exhausting gas, the pressing roller 107 descends. During the descending process, due to the elastic action of the spring rod 203, the roller shaft 202 moves in the reverse direction. At this time, it rises. At this time, the cloth is located between the roller shaft 202 and the pressing roller 107. When coating, the roller shaft 202 and the pressing roller 107 squeeze the cloth so that the raw materials on its surface are squeezed to discharge air bubbles.
