The second cleaning roller is rotated by the second transmission shaft, and the first cleaning rollers on both sides rotate symmetrically, laying the film flat on both sides, thereby removing wrinkles from the film. The cleaning and laying are carried out simultaneously. The dust raised is sucked up by the vacuum cleaner, thus completing the cleaning work and ensuring the cleanliness of the film. The spring rod generates elasticity when the film is guided by the first guide roller, which generates a pulling force on the film, so that the film has a tension effect and avoids shrinkage and wrinkles.

[0022] (3) During operation, by rotating the threaded rod, the distance between the two flat scraper rods is adjusted. The film enters the coating box through the feed trough. The glue guide tube sprays the glue onto the surface of the film through the atomizing nozzle. The glue on the film surface is smoothed by the flat scraper rod to fix the thickness of the glue. The excess glue flows along the guide shroud to the recycling tank. The glue in the recycling tank can be recovered and reused through the external pipeline, so as to obtain wrinkle-free films with uniform glue thickness everywhere, so as to facilitate one-time, high-quality pressing and molding.

[0032] Please see Figure 1-6 As shown: A laminating device for a composite film includes a worktable 101. A first mounting frame 102, a second mounting frame 103, and a third mounting frame 104 are sequentially mounted on the worktable 101. A plurality of leveling components 200 are vertically mounted side-by-side on the first mounting frame 102. A plurality of adhesive application components 300 are vertically mounted side-by-side on the second mounting frame 103. A pressure roller 400 is mounted in the middle of the third mounting frame 104. Each leveling component 200 corresponds one-to-one with an adhesive application component 300. The leveling assembly 200 includes a leveling plate 217. A C-shaped mounting box 207 is provided above the leveling plate 217. A plurality of first cleaning rollers 210 are rotatably mounted on one side of the C-shaped mounting box 207, and a second cleaning roller 214 is rotatably mounted on the other side of the C-shaped mounting box 207. The plurality of first cleaning rollers 210 are parallel to the flow direction of the composite film, and the rotation directions of the first cleaning rollers 210 are symmetrical about the center line of the film. The second cleaning roller 214 is perpendicular to the flow direction of the composite film.

[0033] In this embodiment, each layer of the composite film is installed and exported through the leveling component 200. Various adhesives are evenly applied to both sides of the corresponding film through the corresponding adhesive coating component 300. The film is then pressed together by the pressing roller 400 and formed in one step. When the film passes through the leveling plate 217, the second cleaning roller 214 cleans the surface of the film, raising dust for suction. The first cleaning roller 210, which rotates symmetrically about the center line of the film, rolls the film to both sides to flatten it.

[0034] The leveling component 200 is mounted on the first mounting bracket 102 via a positioning bracket 201. A feeding support bracket 202 is mounted on the side of the positioning bracket 201 away from the second mounting bracket 103. A support seat 204 for mounting the film roll is mounted on the feeding support bracket 202. A leveling support bracket 203 is mounted on the other side of the positioning bracket 201. A leveling table 217 is mounted on the leveling support bracket 203. A vacuum cleaner 205 is located above the leveling table 217. The vacuum cleaner 205 is connected to a C-shaped mounting box 207 via a connecting bracket 206. A leveling motor 208 is mounted in the middle of the inner side of the C-shaped mounting box 207. First transmission shafts 209 are mounted at both ends of the drive shaft of the leveling motor 208. A number of first bevel gears 211 are fixedly sleeved on the shaft 209. A second bevel gear 212 is installed on the end of the first cleaning roller 210 located inside the C-shaped mounting box 207. The first bevel gears 211 and the second bevel gears 212 correspond one-to-one and mesh for transmission. A second drive shaft 213 is installed on both ends of the second cleaning roller 214. A drive sprocket 215 is sleeved on the ends of the two second drive shafts 213 and the corresponding ends of the first drive shafts 209. A drive chain 216 is sleeved on each pair of drive sprockets 215 for transmission. A first guide roller 219 is provided below the flattening plate 217. The two ends of the first guide roller 219 are connected to the flattening support frame 203 through spring rods 218.

[0035] In this embodiment, the film roll is positioned by the support base 204, and the film is laid flat on the flat plate 217. The flat motor 208 rotates the first drive shaft 209, which drives each of the first cleaning rollers 210 through the first bevel gear 211 and the second bevel gear 212. This drives the second drive shaft 213 to rotate the second cleaning roller 214, causing the first cleaning rollers 210 on both sides to rotate symmetrically, spreading the film flat to both sides, thereby removing wrinkles from the film. This achieves simultaneous cleaning and spreading. The dust and debris raised are sucked up by the vacuum cleaner 205, thus completing the cleaning work and ensuring the cleanliness of the film. The spring rod 218 generates elasticity when guiding the film with the first guide roller 219, which generates a pulling force on the film, giving the film a tension effect and preventing shrinkage and wrinkles.

[0036] The glue application assembly 300 is mounted on the second mounting bracket 103 via a positioning seat 301. A glue application box 302 is rotatably mounted in the center of the positioning seat 301, and the positioning seat 301 positions the rotation angle of the glue application box 302 to adjust its posture. A feed chute 303 is provided at one end of the glue application box 302 near the first mounting bracket 102, and a discharge chute 304 is provided at the other end. Second guide rollers 305 are mounted on both sides of the glue application box 302 near the feed chute 303. Glue guide tubes 306 are installed inside the glue application box 302 on both sides near the feed chute 303. Several symmetrically arranged and evenly distributed atomizing nozzles 307 are installed on the opposite sides of the two guide tubes 306. The glue application box 302 is located in the middle of both sides... Each container is equipped with a recycling box 308. The side of the recycling box 308 away from the inner wall of the coating box 302 is open. A support plate 309 is installed in the middle of the inner side of the recycling box 308. A flow guide 311 is movably covered on the side of the support plate 309 near the opening of the recycling box 308. A recycling groove 310 is embedded in the bottom inner side of the recycling box 308 and on both sides of the support plate 309. The recycling groove 310 is connected to the inside of the recycling box 308. A flat scraper 312 is installed on the top of the flow guide 311. A threaded cylinder 313 is fixedly inserted through the middle of the support plate 309. The threaded cylinder 313 is sealed and fixed through the side wall of the coating box 302. A threaded rod 314 is threaded through the middle of the threaded cylinder 313. The end of the threaded rod 314 is hinged to the flow guide 311.

[0037] In this embodiment, by rotating the threaded rod 314, the distance between the two flat scraper rods 312 is adjusted. The film enters the coating box 302 through the feed trough 303. The adhesive guide tube 306 sprays the adhesive onto the surface of the film through the atomizing nozzle 307. The adhesive on the surface of the film is smoothed by the flat scraper rods 312 to fix the thickness of the adhesive. Excess adhesive flows along the guide cover 311 to the recycling tank 310. The adhesive in the recycling tank 310 can be recovered and reused through the external pipeline, thereby obtaining wrinkle-free films with uniform adhesive thickness in each layer, so as to facilitate one-time, high-quality pressing and molding.

[0038] In use, during operation, the various layers of the composite film are installed and exported through the leveling component 200. Various adhesives are evenly applied to both sides of the corresponding film through the corresponding gluing component 300. The film is then pressed together by the pressing roller 400 in one step. When the film passes through the leveling plate 217, the second cleaning roller 214 cleans the surface of the film, raising dust for suction. The first cleaning roller 210, which rotates symmetrically about the center line of the film, rolls the film to both sides to flatten it, thereby keeping the film flat and preventing wrinkles.

[0039] During operation, the film roll is positioned by the support base 204, and the film is laid flat on the flat table 217. The flat motor 208 rotates the first drive shaft 209, which drives each first cleaning roller 210 through the first bevel gear 211 and the second bevel gear 212. This drives the second drive shaft 213 to rotate the second cleaning roller 214, causing the first cleaning rollers 210 on both sides to rotate symmetrically, laying the film flat on both sides, thereby removing wrinkles from the film. This achieves simultaneous cleaning and laying. The dust and debris raised are sucked up by the vacuum cleaner 205, thus completing the cleaning work and ensuring the cleanliness of the film. The spring rod 218 generates elasticity when the film is guided by the first guide roller 219, which generates a pulling force on the film, giving the film a tension effect and preventing shrinkage and wrinkles.

[0040] During operation, by rotating the threaded rod 314, the distance between the two flat scraper rods 312 is adjusted. The film enters the coating box 302 through the feed trough 303. The adhesive guide tube 306 sprays the adhesive onto the surface of the film through the atomizing nozzle 307. The adhesive on the film surface is smoothed by the flat scraper rods 312 to fix the thickness of the adhesive. Excess adhesive flows along the guide shroud 311 to the recycling tank 310. The adhesive in the recycling tank 310 can be recovered and reused through the external pipeline, thereby obtaining wrinkle-free films with uniform adhesive thickness in each layer, so as to facilitate one-time, high-quality pressing and molding.

[0041] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
