Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wall cloth production, and particularly relates to a coating impregnation setting system for intelligent production of glass fiber wall cloth. BACKGROUND

[0002] Glass fiber wall cloth (also known as glass fiber wall cloth) is an important building and decoration material, which is widely used in wall reinforcement, crack prevention, thermal insulation system and high-end interior decoration due to its excellent properties such as high strength, corrosion resistance, fire and mildew resistance, and dimensional stability. Its typical production process includes coating impregnation (usually using acrylic emulsion and other adhesives) of glass fiber cloth substrate and subsequent drying and setting. In this process, the impregnated cloth belt needs to pass through the drying tunnel and go through pre-drying, curing, cooling and other stages to achieve uniform coating, full curing and final setting of the adhesive.

[0003] The impregnation setting device in the prior art usually includes an impregnation tank, a pre-drying zone, a curing zone and a cooling zone arranged in sequence. The cloth belt is supported and pulled forward by a series of supporting rollers when passing through the drying tunnel. However, in actual production, due to uneven tension of the cloth base, hot air impact, parallel error of the supporting rollers and other factors, the cloth belt is prone to local wrinkles or transverse deviation during high-temperature drying. The existing device mainly relies on the experience of operators to macroscopically adjust the tension and supporting rollers, which has a lagging response and is difficult to eliminate the local defects that have been formed in real time and accurately. Wrinkles not only lead to uneven distribution of adhesive in the area, insufficient drying, and affect the uniformity of product performance, but also cause permanent damage to the cloth surface, which becomes a weak point in subsequent winding and use. In addition, for the areas that have wrinkles, the existing continuous drying process lacks targeted remedial measures, resulting in local quality defects in the product.

[0004] Therefore, there is an urgent need for a coating impregnation setting system that can intelligently identify defects in cloth belt conveying and actively correct and compensate for online drying in real time, in order to improve the product quality stability and production efficiency of glass fiber wall cloth.

[0033] In one embodiment, as shown in FIG. 1, the cloth belt 100 is arranged in the impregnation assembly 200, and the cloth belt 100 is impregnated with rubber material in the impregnation tank 210. Figures 1-3As shown, a coating impregnation setting system for intelligent production of glass fiber wall body cloth, comprising an impregnation assembly 200, a central control module 300, a drying tunnel mechanism 400 and a tunnel shell 600, the impregnation assembly 200 is connected to the feeding device, which is used to impregnate the cloth tape 100 from the cloth unwinding device; The drying tunnel mechanism 400 is arranged on the side of the impregnation assembly 200 and comprises a tunnel shell 600 and a plurality of functional areas distributed inside the tunnel shell 600, the functional areas are pre-drying area 620, curing area 630 and cooling area 640 in turn, each functional area is equipped with a heating assembly 700 and a plurality of pull-up roller assemblies 800, a plurality of defect monitoring units 900 are arranged on the heating assembly 700 along the cloth tape 100 conveying path, the defect monitoring unit 900 is used to monitor the cloth tape 100 by vision, to obtain conveying monitoring data and transmit to the central control module 300, wherein the conveying monitoring data at least includes wrinkle defect data, a plurality of said pull-up roller assemblies 800 are arranged at equal intervals, which is used to roll and support the cloth tape 100 and eliminate the wrinkles and deviation on the surface of the cloth tape 100 by symmetrically pulling the edges of the cloth tape 100;

[0034] The pre-drying area 620, the curing area 630 and the cooling area 640 have two heat insulation curtains 610 between each other and form a compensation area 650 between the two heat insulation curtains 610, the compensation area 650 is provided with a supplementary drying assembly 660 inside, the supplementary drying assembly 660 is used to perform supplementary drying on the wrinkle area of the cloth tape 100 passing through the inside of the compensation area 650; The central control module 300 is in communication connection with the pull-up roller assembly 800, the defect monitoring unit 900 and the supplementary drying assembly 660, the central control module 300 issues execution action instructions to the pull-up roller assembly 800 and the supplementary drying assembly 660 based on the conveying monitoring data transmitted by the defect monitoring unit 900, to eliminate the wrinkle defects of the cloth tape 100 and perform supplementary drying on the position of the wrinkle defects.

[0035] In the embodiment of the present application, the two ends of the cloth belt 100 are connected with the cloth unwinding device and the winding device respectively, so as to realize that the cloth belt 100 passes through the impregnation assembly 200 and the drying tunnel mechanism 400. When the cloth belt 100 passes through the impregnation assembly 200, the impregnation assembly 200 performs coating impregnation on the cloth belt 100, so that the glue material is attached to the surface of the cloth belt 100. The impregnated cloth belt 100 is transported into the drying tunnel mechanism 400 and sequentially passes through the pre-drying area 620, the curing area 630 and the cooling area 640. The pre-drying area 620, the curing area 630 and the cooling area 640 are internally provided with a heating assembly 700, which performs drying treatment on the surface of the cloth belt 100. During the drying treatment process of the cloth belt 100, the cloth belt 100 is supported by the pulling roller assembly 800 in a rolling manner, so as to ensure parallel transportation and avoid the occurrence of recesses, which causes uneven distribution of the glue material on the surface of the cloth belt 100. At the same time, the defect monitoring unit 900 performs real-time visual monitoring on the surface of the cloth belt 100, so as to obtain transportation monitoring data of the cloth belt 100 and transmit the transportation monitoring data to the central control module 300. The central control module 300 determines whether the cloth belt 100 has the problems of wrinkles and deviation during the transportation process based on the transportation monitoring data. If the surface of the cloth belt 100 has the problems of wrinkles and deviation, the positions of the wrinkles and the deviation are determined, the central control module 300 issues a correction instruction to the two groups of pulling roller assemblies 800 near the wrinkles and the deviation, the pulling roller assemblies 800 symmetrically pull the edges of the cloth belt 100 after receiving the correction instruction, and the cloth belt 100 is transported in a tensioned state, so as to eliminate the problems of wrinkles and deviation. The central control module 300 also issues a supplementary drying instruction to the supplementary drying assembly 660 in the compensation area 650 where the wrinkles and the deviation will enter. After the area of the surface of the cloth belt 100 with wrinkles and deviation enters the compensation area 650, the supplementary drying assembly 660 starts to work, adjusts the drying data, the position and the drying time, effectively supplements the drying effect of the cloth belt 100 caused by the covering of the wrinkles and the deviation, so as to ensure the uniformity of the drying and shaping of the surface of the cloth belt 100. If the problems of wrinkles and deviation occur, the pulling roller assemblies 800 and the supplementary drying assembly 660 remain in the original state. The pre-drying area 620 adopts medium-low temperature (such as 120-160℃), mainly for rapid evaporation of water, prevention of coating “sagging” and preliminary shaping. The curing area 630 is a high-temperature area (such as 180-220℃), so that the glue material occurs cross-linking reaction, completely forms a film and is cured, and finally gives the product the properties of alkali resistance and mechanical properties. The cooling area 640 is a cooling area (80-100℃), which is a natural cooling or forced cooling section, so that the temperature of the cloth surface is reduced to a safe range before the drying oven, so as to realize stable cooling of the glue layer and avoid thermal stress cracking. The feeding device, the cloth unwinding device and the winding device all adopt the existing technology and do not belong to the improvement field of the present application, so they are not described here.

[0036] In one embodiment, as Figures 1-3As shown, each functional area is further provided with a dehumidification fan 670, which is arranged at the top of the drying tunnel mechanism 400 and connected with the corresponding heating assembly 700. The dehumidification fan 670 can blow heated air into each functional area through the heating assembly 700. The defect monitoring unit 900 further comprises a temperature sensor and an air force sensor. The dehumidification fan 670 and the heating assembly 700 are in communication connection with the central control module 300. The central control module 300 is further configured to receive temperature data and air force data transmitted by the temperature sensor and the air force sensor in the defect monitoring unit 900, and issue power adjustment instructions to the dehumidification fan 670 and the heating assembly 700 based on the environmental preset parameters of the functional area. In the embodiment of the present application, the airflow and temperature combination method is used for drying in each functional area, which improves the drying and shaping effect. The temperature and airflow flow rate of drying are controlled by the central control module 300, which effectively adapts to the drying environment of each functional area and ensures the orderly drying and shaping of the cloth body belt 100.

In the embodiment of the present application, the length of the heating pipe 720 is consistent with the conveying direction of the cloth body belt 100 in the functional area. The dehumidification fan 670 directs the airflow to the two flow distribution plates 730 through the air outlet pipe 680 to be sprayed to the surface of the cloth body belt 100 in an inclined manner, so as to realize the airflow flowing in the transverse direction. The airflow also passes between the heating pipe 720 and the cloth body belt 100 to realize the heating of the airflow. The two heating assemblies 700 are arranged symmetrically above and below, which can realize the synchronous drying of the upper and lower surfaces of the cloth body belt 100. The airflow flows transversely and carries away the moisture of the cloth body belt 100. The airflow mixed with the moisture returns to the dehumidification fan 670 through the air return pipe 690. After the dehumidification fan 670 removes the moisture, the airflow is directed to the flow distribution plate 730 through the air outlet pipe 680, so as to realize the circulation of the hot airflow and improve the utilization rate of the heat resource.

[0044] The above embodiment provides a coating impregnation and shaping system for intelligent production of glass fiber wall cloth, and the working principle is as follows:

[0045] The system mainly comprises three stages of impregnation, drying and shaping, intelligent monitoring and regulation, and cooperatively completes the continuous, uniform and high-quality coating impregnation and drying and curing of the glass fiber cloth body belt (hereinafter referred to as "cloth body belt 100").

[0046] First stage: coating impregnation and pretreatment

[0047] Cloth body introduction and impregnation: the cloth body belt 100 is introduced from the cloth body unwinding device and firstly passes through the impregnation assembly 200; the cloth body belt 100 passes around the guide roller 220 and enters above the impregnation tank 210.

[0048] Impregnation depth adjustment: the central control module 300 can control the height of the roller frame 243 and the guide roller 244 therein through the air cylinder 242 to accurately press down the cloth body belt 100 to immerse in the glue in the impregnation tank 210, so as to ensure the impregnation depth.

[0049] Sizing Condition Maintenance: Sizing monitoring probes 245 (including liquid level meter and vibration viscometer) inside the impregnation tank 210 monitor the liquid level and viscosity of the sizing in real time. When the liquid level is too low, the feeding device is triggered to replenish; the viscosity data is sent to the central control module 300, which controls the vibration frequency of the vibrator 260 to keep the sizing in the appropriate and uniform viscosity range, preventing sedimentation or stratification, and ensuring the uniformity of coating adhesion.

[0050] Initial Control of Sizing Layer Thickness: After impregnation, the fabric belt 100 is drawn out of the impregnation tank 210 and passes through the filter zone formed by the guide roller 230 and the sizing roller 250; the pressure between the two can be adjusted to squeeze excess sizing liquid from the surface of the fabric belt 100, achieving initial and precise control of the attached sizing layer thickness.

[0051] Second Stage: Intelligent Drying and Shaping with Process Control

[0052] After the fabric belt 100 is impregnated, it enters the drying tunnel mechanism 400 for segmented drying and curing.

[0053] Segmented Drying Process:

[0054] Pre-drying area 620: The fabric belt 100 first enters this area. The central control module 300 controls the heating components 700 (heating pipes 720) symmetrically arranged above and below to generate medium-low temperature (e.g. 120-160°C), while starting the dehumidification fan 670 to blow the heated dry air uniformly and obliquely to the upper and lower surfaces of the fabric belt 100 through the diffuser plate 730. The main purpose is to quickly evaporate the water or solvent in the coating, allowing the coating to be initially shaped and preventing "sagging" phenomenon.

[0055] Curing area 630: The fabric belt 100 enters the high temperature area (e.g. 180-220°C). In this area, higher temperature promotes the cross-linking and curing reaction of the sizing, forming a stable film layer and giving the product final alkali resistance and mechanical properties. The heating and air circulation mode is similar to that of the pre-drying area 620, but the temperature is higher.

[0056] Cooling area 640: After the fabric belt 100 enters this area, the heating components 700 stop heating or maintain low temperature, and through natural cooling or lower temperature circulating air, the temperature of the fabric belt 100 gradually decreases to a safe range (e.g. below 80°C) to avoid thermal stress causing the sizing layer to crack, achieving stable shaping.

[0057] Compensation area 650: Located between the pre-drying area 620 and the curing area 630, and between the curing area 630 and the cooling area 640, this is a heat-insulated area. The supplementary drying components 660 inside do not work or maintain basic heat preservation under normal circumstances. The main function is to respond to the instructions of the central control module 300 to perform supplementary drying on specific areas.

[0058] Intelligent process regulation and environment maintenance:

[0059] Hot air circulation: In each functional area, the dehumidification fan 670 drives the airflow to pass through the heating assembly 700 for heating, and then blows to the cloth belt 100, after taking away the moisture, part of the humid airflow is extracted back through the return air pipe 690, and after dehumidification by the dehumidification fan 670, it is heated and recycled, improving the heat energy utilization efficiency.

[0060] Closed-loop control of environmental parameters: The temperature sensor and air force sensor integrated in the defect monitoring unit 900 in each functional area monitor the temperature and airflow speed of the area in real time, and feed back the data to the central control module 300. The central control module 300 compares the real-time data with the environmental preset parameters (target temperature, air speed) of each area, dynamically adjusts the power of the heating assembly 700 and the speed of the dehumidification fan 670, and ensures that each functional area is always in the optimal drying environment.

[0061] Intelligent detection and active elimination of wrinkles and deviation:

[0062] Real-time visual monitoring: All the defect monitoring units 900 (visual monitoring part) arranged on the heating assembly 700 continuously capture and analyze the images of the surface of the cloth belt 100 in conveying, identify whether there are defects such as wrinkles and deviation, and transmit the conveying monitoring data containing the defect position information to the central control module 300 in real time.

[0063] Active pulling and deviation correction: When the central control module 300 determines that there is a wrinkle or deviation at a certain position, it will immediately calculate the pulling roller assembly 800 where the defect position will arrive. The pulling unit 830 of the two pulling roller assemblies 800 at this position and nearby is instructed. The upper electromagnetic plate 834 of the pulling unit 830 is powered on to generate magnetic repulsion, pushing the pulling frame 832 to press down, so that the pulling pressure roller 836 and the lower supporting roller piece 820 jointly clamp the edge of the cloth belt 100. Then, the pulling air cylinder 833 acts to drive the two movable rod seats 831 to move synchronously and reversely along the width direction of the cloth belt 100, thereby symmetrically pulling the edges of the cloth belt 100 on both sides, generating a transverse tension in the local area, and rapidly flattening the wrinkles and correcting the deviation.

[0064] Additional drying for wrinkled areas: Simultaneously with the traction command, the central control module 300 calculates the compensation zone 650 into which the wrinkled / offset area will enter, and issues a command to the additional drying component 660 within the compensation zone 650. The adjusting motor 665 drives the adjusting screw 663 to rotate, causing the upper and lower fixed-area drying trays 661 to precisely move to the position corresponding to the wrinkled area in the width direction of the fabric belt 100. When this area of ​​the fabric belt 100 enters the compensation zone 650, the fixed-area drying tray 661 starts, using adjusted power to perform targeted additional drying on this localized area, compensating for the uneven drying of the original functional area that might have been caused by previous wrinkles, ensuring uniform and consistent overall drying and shaping quality.

[0065] Online thickness monitoring and feedback:

[0066] Thickness monitoring components 500 are installed before the entrance and after the exit of the drying tunnel mechanism 400, with roller supports 520 providing a flat fabric surface for monitoring. A thickness monitor 540 (combining laser and ultrasonic technology) non-contactly measures the thickness of the adhesive layer on the surface of the fabric strip 100. Monitoring data at the entrance can be used to verify the impregnation and extrusion effects and as a reference for process adjustments.

[0067] Monitoring data at the outlet is a key indicator of final product quality. The data is fed back to the central control module 300, where the system can combine the inlet data to analyze the impact of the drying process on thickness. If necessary, it can provide fine-tuning suggestions for front-end impregnation parameters (such as the pressure of the extrusion roller 250) or drying parameters (such as the temperature profile), achieving closed-loop quality control of thickness throughout the entire process.

[0068] Phase 3: Finished product winding

[0069] After complete impregnation, intelligent drying and shaping, and quality control, the fabric belt 100 is led out from the end of the drying tunnel mechanism 400. Its coating has been uniformly cured and stabilized. Finally, it is neatly wound up by the winding device, completing the entire intelligent production process.

[0070] In summary, this system achieves a high degree of automation, intelligence, and high quality in the impregnation and drying process of fiberglass wall fabric through precise adhesive control of the impregnation component 200, zoned precise temperature control and efficient heat circulation of the drying tunnel mechanism 400, online intelligent defect detection based on machine vision, active correction of deviation by the traction roller assembly 800, local remediation by the supplementary drying assembly 660, and thickness monitoring throughout the entire process. This effectively improves product uniformity, stability, and production efficiency.
