Abstract

This utility model discloses a mesh fabric coating device, relating to the field of mesh fabric production technology. The device includes a support frame, with a liquid storage tank fixedly connected to the outer wall of the support frame. A nozzle is fixedly connected to the bottom outer wall of the liquid storage tank. A smoothing mechanism is provided on the outer wall of the support frame, including an electric push rod.

Description

Technical Field

[0001] This utility model belongs to the field of mesh fabric production technology, and in particular relates to a mesh fabric coating device. Background Technology

[0002] According to the published patent CN210522972U, a mesh fabric gluing device is provided. The worktable is equipped with an intermittent feeding assembly, which includes two rotatably mounted first and second rollers. The first rollers are equipped with transmission gears, and intermittent gears mesh with these transmission gears. The gluing assembly includes a glue cylinder mounted on a top plate, with two symmetrical glue outlet pipes fitted on both sides of the bottom of the glue cylinder. Each glue outlet pipe penetrates the top plate downwards and has a glue nozzle at its bottom. An electric switching valve is installed on each glue outlet pipe. The extrusion assembly includes a cylinder and a telescopic piston rod extending through the axial end of the cylinder. The other end of the telescopic piston rod is connected to an extrusion plate. The leveling assembly includes a leveling seat fixedly mounted on the top plate, with a leveling plate fixed to its lower end. This achieves the goal of evenly applying glue to the mesh fabric. However, the following shortcomings still exist: After the above equipment is completed, it simply uses a cylinder to push a piston to make the leveling seat contact the mesh cloth to spread the glue evenly. However, because the pressure generated when the piston rod is pushed is difficult to control precisely, if the pressure on the piston rod is too great after the leveling structure contacts the mesh cloth, it is easy to break the mesh cloth, thus increasing the cost of using the device.

[0007] Furthermore, the adhesive application mechanism includes a motor, the outer wall of which is fixedly connected to the inner wall of the bracket, the output end of which is fixedly connected to a connecting shaft via a coupling, a half gear fixedly connected to the outer wall of the connecting shaft, the outer wall of the half gear being rotatably connected to the inner wall of the bracket, a gear meshing with the outer wall of the half gear, the outer wall of the gear being rotatably connected to the inner wall of the bracket, and a feeding shaft fixedly connected to the outer wall of the gear, the outer wall of the feeding shaft being rotatably connected to the outer wall of the bracket.

[0008] Furthermore, a first pulley is fixedly connected to the outer wall of the connecting shaft, a belt is driven to the inner wall of the first pulley, a second pulley is driven to the outer wall of the belt away from the first pulley, and a fixing plate is fixedly connected to the outer wall of the bracket.

[0009] Furthermore, the outer wall of the fixed plate is rotatably connected to the outer wall of the second pulley, the outer wall of the second pulley is fixedly connected to a support plate, the outer wall of the support plate is rotatably connected to the outer wall of the fixed plate, and the outer wall of the fixed plate is rotatably connected to a second support plate.

[0010] Furthermore, the outer walls of both the support plate and the second support plate are rotatably connected to a first connecting rod, one end of the outer wall of the first connecting rod is rotatably connected to a second connecting rod, the outer wall of the second connecting rod away from the first connecting rod is rotatably connected to a limiting plate, and the outer wall of the limiting plate is rotatably connected to a plurality of paint rollers.

[0011] Furthermore, a limiting block is rotatably connected to the outer wall of the second connecting rod on the side away from the limiting plate.

[0012] This utility model has the following beneficial effects: 1. This utility model incorporates a damper and a spring.

The interaction between the damper and spring can alleviate the instantaneous pressure when the V-shaped scraper plate contacts the mesh cloth, preventing the mesh cloth from breaking due to excessive pressure. The interaction between the damper and spring can also alleviate and absorb the pressure generated when the connecting plate moves, preventing the problem of difficulty in accurately controlling the pressure generated when the piston rod is pushed. If the pressure on the piston rod is too high after the leveling structure contacts the mesh cloth, it may break the mesh cloth, thus increasing the operating cost of the device.

[0013] 2. This utility model incorporates a first connecting rod and a paint roller. The rotation of the support plate drives the first connecting rod to rotate. Since the first connecting rod is located on the outermost side of the support plate, its rotation range is greater than that of the support plate. The rotation of the first connecting rod pushes the second connecting rod to move, which in turn pushes the limiting plate to move back and forth. The movement of the limiting plate drives the two paint rollers to move, and the two paint rollers clamp the mesh fabric. The movement of the paint rollers causes them to rotate on the surface of the mesh fabric. The rotation of the first connecting rod pushes the two paint rollers to move back and forth on the upper and lower sides of the mesh fabric. This prevents the glue from becoming uneven on the surface of the mesh fabric due to gravity and other factors after the glue is sprayed, thus avoiding poor glue application results.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figures 1-5 As shown, this utility model is a mesh cloth adhesive application device, including a support 1, a liquid storage tank 101 is fixedly connected to the outer wall of the support 1, and a nozzle 102 is fixedly connected to the bottom outer wall of the liquid storage tank 101, and the liquid inside the liquid storage tank 101 is sprayed out by the nozzle 102. A smoothing mechanism 2 is provided on the outer wall of the support 1. The smoothing mechanism 2 includes an electric push rod 201. The outer wall of the electric push rod 201 is fixedly connected to the outer wall of the support 1. A connecting plate 202 is fixedly connected to the bottom outer wall of the electric push rod 201. A V-shaped scraper 203 is fixedly connected to the bottom outer wall of the connecting plate 202. The extension of the electric push rod 201 controls the movement of the connecting plate 202, thereby pushing the V-shaped scraper 203 at the bottom of the connecting plate 202 to make slight contact with the surface of the mesh fabric, and using the V-shaped scraper 203 to scrape off the excess glue on the surface of the mesh fabric. Several dampers 205 are fixedly connected to the top outer wall of the connecting plate 202. Springs 206 are fixedly connected to the outer wall of the dampers 205. Due to the dampers 205... 05 is connected to spring 206 and connecting plate 202. During the movement of connecting plate 202, damper 205 and spring 206 are pulled to extend. The cooperation between damper 205 and spring 206 can relieve and absorb the instantaneous pressure between V-shaped scraper 203 and mesh cloth, preventing excessive pressure from causing V-shaped scraper 203 to break the mesh. A fixing block 204 is fixedly connected to the outer wall of the end of damper 205 away from connecting plate 202. Several first connecting rods 207 are rotatably connected to the outer wall of connecting plate 202. Second connecting rods 208 are rotatably connected to the outer wall of the first connecting rods 207. During the movement of connecting plate 202, the first connecting rods 207 are rotated while the second connecting rods 208 are pulled. 08 allows it to rotate around the outside of the fixed block 204, thereby stabilizing the movement of the connecting plate 202 through the interconnection and rotation of the first connecting rod 207 and the second connecting rod 208. The outer wall of the bracket 1 is provided with an adhesive applicator 3. The outer wall of the first connecting rod 207 is rotatably connected to a third connecting rod 209. The outer wall of the third connecting rod 209, away from the first connecting rod 207, is rotatably connected to a first slider 211. As the third connecting rod 209 rotates around the first connecting rod 207, it drives the first slider 211 to slide along the interior of the connecting plate 202. The third connecting rod 209 also shares the pressure of the first connecting rod 207, stabilizing its rotation. The outer wall of the first connecting rod 207 is rotatably connected to a fourth connecting rod. The outer wall of the fourth link 210 is rotatably connected to the second slider 213. As the fourth link 210 rotates around the first link 207, it drives the second slider 213 to move. The fourth link 210 also limits the rotation range of the first link 207 and the second link 208. The bottom of the inner wall of the bracket 1 is fixedly connected to the collection box 212, which collects the scraped excess glue. The outer wall of the spring 206 is fixedly connected to the outer wall of the fixing block 204. The outer wall of the fixing block 204 is fixedly connected to the inner wall of the bracket 1. The outer wall of the first slider 211 is slidably connected to the inner wall of the connecting plate 202. The outer wall of the second slider 213 is slidably connected to the inner wall of the bracket 1.

[0020] The adhesive application mechanism 3 includes a motor 301. The motor 301 is fixedly connected to the inner wall of the bracket 1 via a starting motor. A connecting shaft 302 is fixedly connected to the output end of the motor 301 via a coupling. A half-gear 303 is fixedly connected to the outer wall of the connecting shaft 302. The outer wall of the half-gear 303 is rotatably connected to the inner wall of the bracket 1. The motor 301 drives the half-gear 303 to rotate inside the bracket 1. A gear 304 meshes with the outer wall of the half-gear 303, and the outer wall of the gear 304 rotates with the inner wall of the bracket 1. The connecting shaft 302 is connected to the outer wall of the gear 304, which is fixedly connected to the feeding shaft 305. The half-gear 303 meshes with the gear 304, causing the gear 304 to rotate intermittently, thus controlling the feeding speed of the feeding shaft 305. The outer wall of the feeding shaft 305 is rotatably connected to the outer wall of the support 1. A first pulley 306 is fixedly connected to the outer wall of the connecting shaft 302. A belt 307 is driven through the inner wall of the first pulley 306. The outer wall of the belt 307 furthest from the first pulley 306... A second pulley 308 is movably connected. Since both ends of the belt 307 are connected to the first pulley 306 and the second pulley 308, the belt 307 drives the first pulley 306 and the second pulley 308 to rotate. A fixing plate 309 is fixedly connected to the outer wall of the bracket 1. The outer wall of the fixing plate 309 is rotatably connected to the outer wall of the second pulley 308. The fixing plate 309 stabilizes the rotation of the second pulley 308. A support plate 310 is fixedly connected to the outer wall of the second pulley 308. The outer wall of the support plate 310 is rotatably connected to the outer wall of the fixing plate 309. A second support plate 318 is rotatably connected to the outer wall of the fixing plate 309. Since the support plate 310 and the second support plate 318 have the same external structure, when the second pulley 308 drives the support plate 310 to rotate, the operation of the structure on the outside of the support plate 310 will drive the second support plate 318 to rotate simultaneously. Thus, the rotation of the second support plate 318 drives the same structure to operate, thereby stabilizing the movement of the paint roller 314.

[0021] Both the support plate 310 and the second support plate 318 are rotatably connected to the outer walls of a first connecting rod 311. A second connecting rod 312 is rotatably connected to one end of the outer wall of the first connecting rod 311. As the support plate 310 rotates, the first connecting rod 311 rotates. Since the first connecting rod 311 is located on the outermost side of the support plate 310, its rotation range is greater than that of the support plate 310. The outer side of the second support plate 318 is connected to another identical first connecting rod 311 in the same manner, with corresponding connection positions. The rotation of the first connecting rod 311 can move the second connecting rod 312. A limit plate 313 is rotatably connected to the outer wall of the second connecting rod 312 away from the first connecting rod 311. Several paint rollers 314 are rotatably connected to the outer wall of the limit plate 313. The second connecting rod 312 pushes the limit plate 313... The movement of the limiting plate 313 pushes the two paint rollers 314 to move. The outer wall of the second connecting rod 312 away from the limiting plate 313 is rotatably connected to the limiting block 315. The outer wall of the limiting block 315 is slidably connected to the inner wall of the fixed plate 309. The inner wall of the limiting block 315 is slidably connected to the slide rod 316. The outer wall of the slide rod 316 is fixedly connected to the inner wall of the fixed plate 309. During the movement of the second connecting rod 312, it pushes the limiting block 315 to move along the inside of the bracket 1. At the same time, the slide rod 316 limits the movement range of the limiting block 315. The outer wall of the limiting block 315 is fixedly connected to the pressure spring 317. The outer wall of the pressure spring 317 is fixedly connected to the inner wall of the fixed plate 309. The movement of the limiting block 315 compresses the pressure spring 317, and the elasticity of the pressure spring 317 relieves the pressure when the limiting block 315 moves.

[0022] One specific application of this embodiment is: When the operator needs to use the equipment, the mesh fabric is placed over the outside of the feeding shaft 305. Then, the motor 301 is started, causing the connecting shaft 302 to rotate while simultaneously rotating the half gear 303. Since the half gear 303 meshes with the gear 304, the half gear 303 intermittently drives the gear 304 to rotate, causing the gear 304 to periodically rotate the feeding shaft 305, thus controlling the feeding speed of the mesh fabric. Simultaneously, one end of the mesh fabric is pulled to pass through the rotating shaft and secure it to the other end. The mesh fabric is then horizontally suspended in the middle of the device. Next, the nozzle 102 at the bottom of the liquid storage tank 101 is activated, causing it to periodically spray glue at a frequency matching the rotation frequency of the feeding shaft 305. During the rotation of 02, the first pulley 306 will rotate, and the first pulley 306 will drive the transmission. Since both ends of the belt 307 are connected to the first pulley 306 and the second pulley 308, the transmission of the belt 307 can drive the second pulley 308 and the first pulley 306 to rotate simultaneously. The second pulley 308 will drive the support plate 310 to rotate. The rotation of the support plate 310 will drive the first connecting rod 311 to rotate. Since the first connecting rod 311 is located at the outermost edge of the support plate 310, the rotation range of the first connecting rod 311 is greater than that of the support plate 310. The rotation of the first connecting rod 311 will push the second connecting rod 312 to move, and the second connecting rod... 312 pushes the limiting plate 313 to move back and forth. The movement of the limiting plate 313 drives the two paint rollers 314 to move, and the two paint rollers 314 clamp the mesh cloth. The movement of the paint rollers 314 makes them rotate on the surface of the mesh cloth, thereby spreading the glue evenly on the surface of the mesh cloth. Since a second support plate 318 with the same size as the support plate 310 is provided on the outer side of the fixing plate 309 on the other side of the device, and the second support plate 318 and the support plate 310 drive two identical structures to operate, when the limiting plate 313 moves, an identical structure at the other end will be pushed by the second support plate 318 to operate, thereby stabilizing the movement of the limiting plate 313 and preventing shaking. In the second connecting rod 312 During the movement, the limiting block 315 is pushed to move along the interior of the fixed plate 309. At the same time, the sliding rod 316 limits the movement range of the limiting block 315, allowing the limiting block 315 to fully compress the pressure spring 317. The elasticity of the pressure spring 317 relieves the pressure of the limiting block 315 during movement. Then, the electric push rod 201 is activated to extend downwards, pushing the connecting plate 202 to move the V-shaped scraper 203. The V-shaped scraper 203 makes slight contact with the surface of the mesh fabric. The special shape of the V-shaped scraper 203 scrapes off the excess glue from the mesh surface and collects it in the collection box 212 below. During the movement of the connecting plate 202, the damper 205 and the spring 206 are pulled.The damper 205 and spring 206 work together to alleviate the instantaneous pressure when the V-shaped scraper 203 contacts the mesh fabric, preventing the mesh fabric from breaking due to excessive pressure. During the movement of the connecting plate 202, multiple first connecting rods 207 rotate, while simultaneously causing the second connecting rod 208 to rotate around the outside of the fixed block 204. The connection between the first connecting rods 207 and the second connecting rod 208 stabilizes the movement of the connecting plate 202, and the rotation of the first connecting rod 207 pushes the third connecting rod 209 to rotate around the first connecting rod 204. While the first connecting rod 207 rotates, it drives the first slider 211 to move inside the connecting plate 202. This, combined with the connection and rotation of the third connecting rod 209, stabilizes the movement of the connecting plate 202 and shares the pressure of the first connecting rod 207. The rotation of the first connecting rod 207 pushes the fourth connecting rod 210 to rotate, causing the fourth connecting rod 210 to pull the second slider 213 to move at the bottom of the bracket 1. This, in turn, allows the fourth connecting rod 210 to share the pressure of the first connecting rod 207 and the second connecting rod 208 and limits the range of movement of the connecting plate 202.
