Description

Technical Field

[0001] This utility model relates to the field of mesh fabric processing technology, and in particular to a multi-sided adhesive coating device for mesh fabric. Background Technology

[0002] Fiberglass mesh, also known as fiberglass reinforcing mesh, is made from medium-alkali or alkali-free fiberglass yarn woven into a fiberglass mesh base. This mesh features structural stability, high strength, good alkali resistance, corrosion resistance, and crack resistance, providing optimal reinforcement. Furthermore, it is simple and easy to install. Fiberglass mesh is primarily suitable for laying on the interior and exterior surfaces of cement, plaster, walls, buildings, and other structures to prevent cracking. During production, one or more layers of mesh are coated with an adhesive to improve its mechanical properties.

[0003] Traditional mesh fabric coating processes often employ single-sided coating or impregnation methods, resulting in uneven coating, low efficiency, and the inability to simultaneously coat both sides or multiple sides. Furthermore, adhesive thickness control relies on manual experience, making precise adjustment difficult and leading to adhesive waste or substandard coating results. In continuous production, adhesive flowability, temperature control, and curing efficiency directly impact coating quality and production efficiency. Existing equipment often lacks integrated adhesive quantity detection, thickness adjustment, and rapid curing functions, making it difficult to meet the process requirements of high-performance mesh fabric coating.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0023] like Figure 1 and Figure 2 As shown, this embodiment provides a multi-sided adhesive coating device for mesh fabric. The processing device includes a support base 10, a multi-sided adhesive coating mechanism 20 disposed on the support base 10, a guiding and traction mechanism 30 disposed at the inlet and outlet ends of the multi-sided adhesive coating mechanism 20, and a baking and curing mechanism 40 disposed at the outlet end of the multi-sided adhesive coating mechanism 20. An adjustment mechanism 50 is also provided on the support base 10, and the multi-sided adhesive coating mechanism 20 is disposed on the adjustment mechanism 50. The position of the multi-sided adhesive coating mechanism 20 can be adjusted by the adjustment mechanism 50. The multi-sided adhesive coating mechanism 20 consists of an upper layer... The system consists of an upper coating assembly 21 and a lower coating assembly 22. The mesh fabric's degree of freedom is introduced through the guide traction mechanism 30 at the feed end of the multi-faceted coating mechanism 20, passing between the upper coating assembly 21 and the lower coating assembly 22. The upper coating assembly 21 and the lower coating assembly 22 apply adhesive to the mesh fabric. After the mesh fabric is coated with adhesive, it is pulled to the baking and curing mechanism 40 by the guide traction mechanism 30 at the feed end of the multi-faceted coating mechanism 20. The baking and curing mechanism 40 cures the adhesive on the mesh fabric to a certain extent, preventing the adhesive from dripping from the mesh fabric.

[0024] The adjustment mechanism 50 includes a slide rail assembly 51 located on the end face of the support base 10 and a slide block 52 located on the slide rail assembly 51. The upper glue application assembly 21 and the lower glue application assembly 22 are respectively located on the slide block 52. The slide block 52 is provided with a screw push block 53. The support base 10 is provided with an adjustment screw 54 rotatably connected to the support base 10 via a bearing shaft. The adjustment screw 54 is threadedly connected to the screw push block 53. A handwheel is provided on the end of the adjustment screw 54 away from the screw push block 53. By rotating the handwheel, the adjustment screw 54 is adjusted, causing the screw push block 53 connected to the adjustment screw 54 to push the slide block 52, thereby moving the multi-sided glue application mechanism 20 back and forth along the slide rail assembly 51. This adjusts the position of the multi-sided glue application mechanism 20 and the guide traction mechanisms 30 on both sides, preventing deviations in the position where the guide traction mechanisms 30 introduce the mesh cloth.

[0025] In this embodiment, the guide traction mechanism 30 is used to guide the direction of the mesh fabric, and includes a support 31 and guide rollers 32 arranged side by side on the top of the support 31.

[0026] In this embodiment, the baking and curing mechanism 40 is used to dry the adhesive on the mesh cloth. It includes a support 41, a heat-concentrating cover 42 disposed on the support 41, and a heating element 43 disposed in the heat-concentrating cover 42. The mesh cloth passes through the port of the heat-concentrating cover 42, and the heat emitted by the heating element 43 passes through the port of the heat-concentrating cover 42 to cure the adhesive on the mesh cloth to a certain extent, so as to prevent the adhesive from falling off the mesh cloth.

[0027] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the upper coating assembly 21 is used to coat the upper surface of the mesh cloth. The upper coating assembly 21 includes a height adjustment component 210, an upper glue base 211, a pouring shaft 212, an upper coating shaft 213, an upper actuation unit 214, an upper shaft drive unit 215, and a detection unit 216. The upper glue holder 211 has a receiving groove 2111 at its bottom. The upper glue holder 211 has a first mounting hole 2112 and a second mounting hole 2113 for connecting to the pouring shaft 212 and the upper glue-coating shaft 213. The first mounting hole 2112 is located above the second mounting hole 2113. The pouring shaft 212 is rotatably connected to the first mounting hole 2112 via a bearing and is driven to rotate by the upper actuating unit 214. The upper glue-coating shaft 213 is rotatably connected to the second mounting hole 2113 via a bearing and is driven to rotate by the upper shaft driving unit 215. Part of the pouring shaft 212 is located within the receiving groove 2111, and the pouring shaft 212 has an upper glue-bearing groove. 2120; The upper glue holder 211 is provided with two first glue inlet channels, which intersect with the upper glue outlet. The outlet of the upper glue outlet is connected to the receiving groove 2111. The two first glue inlet channels are respectively connected to the first connectors 2114. The upper glue holder 211 is provided with first blocking cylinders 2115 to block the two first glue inlet channels respectively. The output end of each first blocking cylinder 2115 is provided with a first plug to block the first glue inlet channel. The upper glue holder 211 is provided with a clearance groove 2116 that gradually slopes inward from top to bottom on the side. The clearance groove 2116 corresponds to the detection unit 216. The bottom of the clearance groove 2116 is flush with the end face of the lower glue coating shaft 221. When the above-mentioned upper coating assembly 21 is working, the upper actuation unit 214 drives the pouring shaft 212 to rotate, so that the upper glue-bearing groove 2120 corresponds to the upper glue outlet, so that the glue flowing into the upper glue outlet through the first glue inlet channel flows into the upper glue-bearing groove 2120. When a certain amount of glue is delivered, the first sealing cylinder 2115 drives the first plug to block the first glue inlet channel to prevent the glue from being delivered further. When the upper glue-bearing groove 2120 is filled with a certain amount of glue, the upper actuation unit 214 drives the pouring shaft 212 to rotate, so that the glue in the upper glue-bearing groove 2120 is poured onto the upper coating shaft 213. When the detection unit 216 detects that there is glue on the upper coating shaft 213, the upper shaft drive unit 215 drives the upper coating shaft 213 to rotate, so that the glue is coated onto the mesh cloth during the rotation of the upper coating shaft 213, thereby achieving the coating of glue on the upper side of the mesh cloth.

[0028] The height adjustment component 210 is used to adjust the height of the upper glue seat 211. The height adjustment component 210 includes a guide rail 2101 vertically mounted on the slide 52 and an adjustment seat 2102 slidably mounted on the guide rail 2101. The adjustment seat 2102 is provided with a vertical adjustment screw 2103 threadedly connected to the slide 52. The upper glue seat 211 is mounted on the adjustment seat 2102. By rotating the vertical adjustment screw 2103, the height of the upper glue seat 211 can be adjusted, thereby cooperating with the lower glue coating component 22 to meet the glue coating requirements of different sizes of mesh cloth.

[0029] In this embodiment, the detection unit 216 includes an L-shaped plate 2160 fixed on the adjustment seat 2102. The L-shaped plate 2160 has a small-angle bend, and the bend has a sensor 2161 corresponding to the clearance groove 2116. The sensor 2161 can accurately detect whether there is glue on the upper adhesive shaft 213. When the upper adhesive shaft 213 rotates to the detection position corresponding to the sensor 2161, if there is glue on the shaft, the sensor 2161 will immediately send a signal. This signal is transmitted to the upper shaft drive unit 215, triggering the upper shaft drive unit 215 to start, thereby driving the upper adhesive shaft 213 to rotate at a set speed and direction, ensuring that the glue is evenly and stably coated on the upper side of the mesh cloth.

[0030] In an optional embodiment, the upper shaft drive unit 215 includes an upper shaft drive motor fixed on the adjusting seat 2102, a drive sprocket located at the output end of the upper shaft drive motor, and a driven sprocket located at one end of the upper adhesive application shaft 213. The drive sprocket and the driven sprocket are connected by a chain, and a movable slot is provided on the slide 52 for the output shaft of the upper shaft drive motor to move up and down. The upper shaft drive motor drives the drive sprocket to rotate, and the drive sprocket then drives the driven sprocket to rotate via the chain, thereby driving the upper adhesive application shaft 213 to rotate stably at a set speed and direction, achieving uniform coating of adhesive on the side of the mesh fabric. This sprocket and chain drive method has a simple and reliable structure, high transmission efficiency, and can ensure that the upper adhesive application shaft 213 maintains a stable speed during long-term operation, thereby improving the quality and consistency of adhesive application. In other embodiments, the upper shaft drive unit 215 can use a combination of synchronous pulleys, synchronous belts, and motors to achieve transmission, or a combination of gears and motors to achieve transmission, or a rotary cylinder, etc., which will not be described in detail in this embodiment.

[0031] like Figure 7 , Figure 8 and Figure 9 As shown, the lower adhesive application assembly 22 is used to apply adhesive to the lower side of the mesh fabric. The lower adhesive application assembly 22 includes an adhesive support 220, a lower adhesive application shaft 221, an adhesive scraper shaft 222, a lower actuation unit 223, and a lower shaft drive unit 224. The adhesive support 220 has a lower adhesive support groove 2201 at its top, which communicates with the lower adhesive outlet. A liquid level sensor 2202 for detecting the adhesive level is located on the side wall of the lower adhesive support groove 2201. The upper side of the adhesive support 220 has a third mounting hole 2203 and a fourth mounting hole 2204 for connecting to the lower adhesive application shaft 221 and the scraper shaft 222. The third mounting hole 2203 is located at the upper end of the fourth mounting hole 2204. The lower adhesive application shaft 221 is rotatably connected to the third mounting hole 2203 via a bearing and is driven to rotate by the lower shaft drive unit 224. The scraper shaft 2202... 22 is rotatably connected to the fourth mounting hole 2204 via a bearing, and the scraper shaft 222 is located in the lower glue-bearing groove 2201 and is driven to rotate by the lower actuating unit 223; in addition, the glue-bearing seat 220 is provided with two second glue inlet channels, which intersect with the downstream glue outlet; the two second glue inlet channels are respectively connected to a second connector 2205; the downstream glue outlet is provided with a second sealing cylinder 2206 to block the two second glue inlet channels respectively, and the output end of each second sealing cylinder 2206 is provided with a second plug to block the second glue inlet channel; When adhesive application is required, the second sealing cylinder 2206 is activated, causing the second plug to leave the second adhesive inlet channel. The adhesive enters the two second adhesive inlet channels through the second connector 2205, and then flows into the lower adhesive receiving tank 2201 through the downstream adhesive outlet. The liquid level sensor 2202 monitors the height of the adhesive in the lower adhesive receiving tank 2201 in real time and feeds the signal back to the control system. When the adhesive reaches the set height, the control system controls the second sealing cylinder 2206 to activate again, causing the second plug to block the second adhesive inlet channel and prevent the adhesive from continuing to flow in and causing overflow. The lower shaft drive unit 224 is started, driving the lower adhesive application shaft 221 to rotate at the set speed and direction, so as to evenly coat the adhesive in the lower adhesive receiving tank 2201 onto the lower side of the mesh cloth.

[0032] To avoid excessive adhesive thickness on the lower side and ensure uniform adhesive application, a scraper groove 2220 is provided on the scraper shaft 222. The scraper shaft 222 is driven to rotate by the lower actuation unit 223, causing the scraper groove 2220 to scrape off the adhesive on the surface of the lower adhesive shaft 221. The scraped adhesive flows back into the lower adhesive receiving groove 2201 through the scraper groove 2220, making the adhesive layer more uniform and flat, and improving the uniformity of adhesive application.

[0033] In an optional embodiment, the lower shaft drive unit 224 includes a lower shaft drive motor fixed on the slide 52, a drive sprocket located at the output end of the lower shaft drive motor, and a driven sprocket located at one end of the upper adhesive application shaft 213. The drive sprocket and the driven sprocket are connected by a chain. The lower shaft drive motor drives the drive sprocket to rotate, and the drive sprocket then drives the driven sprocket to rotate via the chain, thereby driving the lower adhesive application shaft 221 to rotate stably at a set speed and direction, achieving uniform coating of adhesive on the upper side of the mesh fabric. This sprocket and chain drive method has a simple and reliable structure, high transmission efficiency, and can ensure that the upper adhesive application shaft 213 maintains a stable speed during long-term operation, thereby improving the quality and consistency of adhesive application. In other embodiments, the lower shaft drive unit 224 can use a combination of synchronous pulleys, synchronous belts, and motors to achieve transmission, or a combination of gears and motors to achieve transmission, or a rotary cylinder, etc., which will not be described in detail in this embodiment.

[0034] To ensure rapid flow of the adhesive within the upstream glue holder 211 and the downstream glue holder 220, and to prevent the adhesive from solidifying and clogging the flow channels, heating tubes 60 are installed in both spaces. These heating tubes 60 heat the upstream glue holder 211 and the downstream glue holder 220, maintaining the adhesive within a suitable flow temperature range. This not only accelerates the flow rate of the adhesive within the flow channels, improving coating efficiency, but also effectively prevents the adhesive from solidifying due to excessively low temperatures, thus avoiding channel blockage. The heating tubes 60 can be electrically heated, with precise temperature control via a temperature controller to ensure the stability and reliability of the heating process, thereby guaranteeing the normal operation of the entire adhesive coating process and the quality of the coating.

[0035] In this embodiment, the upper actuation unit 214 and the lower actuation unit 223 adopt the same structure. The upper actuation unit 214 and the lower actuation unit 223 drive the corresponding pouring shaft 212 and the scraping shaft 222 to rotate. The upper actuation unit 214 and the lower actuation unit 223 both include a swing arm 2140 and a telescopic cylinder 2141 that drives the swing arm 2140. The telescopic cylinder 2141 is fixed on the corresponding upper glue seat 211 and glue receiving seat 220 through the mounting base. One end of the swing arm 2140 is fixedly connected to the corresponding pouring shaft 212 and the scraping shaft 222, and the other end is pivotally connected to the telescopic cylinder 2141. Then, the telescopic cylinder 2141 drives the swing arm 2140, thereby driving the pouring shaft 212 and the scraping shaft 222 to rotate.

[0036] In summary, this multi-sided adhesive coating device for mesh fabric achieves simultaneous and uniform adhesive coating on both the upper and lower sides of the mesh fabric through its ingenious structural design. The support base 10 serves as the foundation of the entire device, providing a stable support platform for the multi-sided adhesive coating mechanism 20, the guiding and traction mechanism 30, the baking and curing mechanism 40, and the adjustment mechanism 50. In the multi-sided adhesive coating mechanism 20, the upper adhesive coating component 21 and the lower adhesive coating component 22 cooperate with each other. The upper adhesive coating component 21 uses components such as the pouring shaft 212 and the upper adhesive coating shaft 213 to precisely apply adhesive to the upper side of the mesh fabric. The lower adhesive coating component 22 uses components such as the lower adhesive coating shaft 221 and the scraper shaft 222 to evenly apply adhesive to the lower side of the mesh fabric. The scraper shaft 222 effectively avoids the problem of excessive adhesive thickness, ensuring the uniformity and smoothness of the adhesive coating. The guiding traction mechanism 30 plays a crucial guiding role in the mesh fabric adhesive application process. The support 31 and guide roller 32 ensure that the mesh fabric can accurately and smoothly enter and exit the multi-faceted adhesive application mechanism 20, avoiding deviations in the mesh fabric's orientation that could affect the adhesive application quality. The baking and curing mechanism 40 promptly dries the adhesive-coated mesh fabric. The combination of the heat-concentrating cover 42 and the heating element 43 allows heat to be concentrated and effectively applied to the adhesive on the mesh fabric, curing the adhesive to a certain extent, preventing adhesive dripping, and ensuring convenience for subsequent processing and use. The existence of the adjustment mechanism 50 makes this processing device more adaptable. By rotating the adjusting screw 54 with the handwheel, the slide 52 and the multi-faceted adhesive application mechanism 20 are moved back and forth along the slide rail assembly 51, allowing for convenient adjustment of the positional relationship between the multi-faceted adhesive application mechanism 20 and the two guiding traction mechanisms 30, thereby meeting the adhesive application requirements of different specifications of mesh fabric. The height adjustment component 210 further enhances the flexibility of the device. By rotating the vertical adjustment screw 2103, the height of the upper glue holder 211 can be adjusted to match the lower glue coating assembly 22, adapting to glue coating operations of different sized mesh fabrics. The heating tube 60 reflects the meticulous and comprehensive design of the device, heating the upper glue holder 211 and the glue receiving seat 220 to ensure smooth flow of glue in the flow channel, avoiding the problem of glue solidification and blockage of the flow channel, and improving the glue coating efficiency and the stability of device operation. The upper actuation unit 214 and the lower actuation unit 223 adopt the same simple and effective structure. The telescopic cylinder 2141 drives the swing arm 2140, which in turn drives the pouring shaft 212 and the glue scraper shaft 222 to rotate, realizing precise control of glue delivery and coating process. The entire processing device has a compact structure and reasonable design. The components work together to provide an efficient, stable, and reliable solution for multi-sided glue coating of mesh fabric, improving production efficiency while ensuring glue coating quality.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
