[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] Example 1, by Figures 1-4 The present invention relates to a lamination device for rapid curing of film and cardboard, comprising a base 1, a lamination assembly 2 disposed at the top center of the base 1, a film roll-out mechanism 3 mounted on the base 1 for rolling out the film, and cardboard conveying assemblies 4 symmetrically disposed on both sides of the lamination assembly 2.

[0016] The composite lamination assembly 2 includes a central mounting frame 201 fixedly mounted on the base 1. A hot press roller 202 is symmetrically rotatably arranged on the inner side of the central mounting frame 201. A heater is installed inside the hot press roller 202. A driven gear 203 is coaxially mounted on one end of the rotating shaft of the hot press roller 202. The upper and lower driven gears 203 are meshed and connected. The lower driven gear 203 is meshed and connected to a driving gear 204. The driving gear 204 is fixedly connected to the output shaft of a rotating motor 205. The rotating motor 205 is fixedly mounted on the base 1. Through the two hot press rollers 202 and the heater installed inside them, when the film and the cardboard pass through the upper and lower hot press rollers 202, a high temperature and high pressure environment is formed, thereby rapidly curing and laminating the film and the cardboard.

[0017] The paper conveying assembly 4 includes a side mounting bracket 401 fixedly mounted on the base 1. Conveying rollers 402 are rotatably mounted at equal intervals on the inner side of the side mounting bracket 401. The top wall of the conveying rollers 402 is flush with the top wall of the hot press rollers 202 below. A transmission component 403 is installed between each conveying roller 402. A paper jam limiting assembly 5 is provided on the top of the side mounting bracket 401 near the feeding side of the two hot press rollers 202. The transmission component 403 includes a first sprocket 4031 and a second sprocket 4032. The first sprocket 4031 and the second sprocket 4032 are respectively mounted on the rotating shafts of two adjacent conveying rollers 402. A chain 4033 is meshed with the outer sides of the first sprocket 4031 and the second sprocket 4032.

[0018] The paper jam limiting assembly 5 includes a baffle housing 501 fixedly installed on the top of the side mounting bracket 401. The baffle housing 501 is located on the side of the side mounting bracket 401 near the hot press roller 202. A bottom groove 502 is opened at the bottom end of the baffle housing 501. A support plate 508 is symmetrically installed at the bottom end of the baffle housing 501. The support plate 508 is fixedly installed on the side mounting bracket 401. A limiting roller 504 is rotatably installed inside the baffle housing 501. The conveying roller 402 and the limiting roller 504 can limit the conveyed paper jam. By the synchronous reverse rotation of the conveying roller 402 and the limiting roller 504, the conveying friction of the paper jam is increased, and the conveying stability of the paper jam is improved. When the film and the paper jam pass between the two hot press rollers 202, lamination is achieved through high temperature and high pressure.

[0019] The limiting roller 504 has an adhesive cavity inside. One end of the limiting roller 504 is fixedly connected to the output shaft of the servo motor 505. The servo motor 505 is fixedly installed at one end of the baffle housing 501. The outer wall of the limiting roller 504 is in close contact with the inner wall of the baffle housing 501. Adhesive outlet holes 506 are evenly distributed on the circumferential sidewall of the limiting roller 504. A feed pipe 503 is fixedly installed at the end of the baffle housing 501 away from the servo motor 505. One end of the feed pipe 503 is inserted into the inner cavity of the limiting roller 504. A rotating... The sealing ring and the feed pipe 503 are connected to an adhesive storage tank containing the pump body. An infrared detector 507 is installed on one of the support plates 508. During the rotation of the limiting roller 504, the adhesive is continuously squeezed from the glue outlet 506 on the limiting roller 504 to the surface of the cardboard, which facilitates the subsequent bonding and lamination of the film and the cardboard. At the same time, since the bottom wall of the baffle housing 501 has a bottom groove 502, the outer wall of the limiting roller 504 is in close contact with the inner wall of the baffle housing 501, so that the adhesive can only be squeezed out from the glue outlet 506 located inside the bottom groove 502, which improves the adhesive extrusion effect.

[0020] Working principle: In use, first install the film roll onto the film roll-out mechanism 3, place a cardboard above the cardboard conveying assembly 4 on the feeding side between the two hot press rollers 202 for conveying. During conveying, since one of the conveying rollers 402 is connected to a drive motor at its shaft end, under the transmission action of the drive motor and the transmission component 403, each conveying roller 402 is driven to rotate, thereby conveying the cardboard between the two hot press rollers 202 and passing one end of the film between the upper and lower hot press rollers 202. When the paper passes between the conveying roller 402 and the limiting roller 504, the paper is limited to ensure that the paper and film fit more closely between the upper and lower hot press rollers 202. At the same time, after the servo motor 505 is turned on, it drives the limiting roller 504 to rotate, so that the conveying roller 402 and the limiting roller 504 rotate synchronously and in opposite directions, thereby improving the stability of paper conveying. When the paper enters below the limiting roller 504, the infrared detector 507 detects the paper moving below the limiting roller 504 through infrared sensing. At this time, the controller controls the pump in the adhesive storage tank containing the pump body to open, driving the adhesive in the adhesive storage tank containing the pump body into the limiting roller 504, and extruding the adhesive from the adhesive outlet 506 onto the surface of the paper. When the film and the paper are fed together between the upper and lower hot press rollers 202, the heaters inside the hot press rollers 202 generate high temperature and high pressure on the film and the paper, thereby achieving rapid curing and lamination of the film and the paper. When the paper passes below the limiting roller 504, the infrared detector 507 detects that the paper has left through infrared sensing, and the controller controls the pump in the adhesive storage tank containing the pump body to close. After the film and cardboard undergoing lamination leave between the two hot press rollers 202, they enter another cardboard conveying assembly 4 for discharge.
