[0025] Specifically: support frame 1 and mounting plate 101 support and install the other devices; conveying device 2 conveys the foam base; feeding device 3 installs the composite film; heating device 4 heats and strengthens the bonding of the film; cutting device 5 performs the cutting work; and linkage device 6 connects and meshes, causing the mounting roller 302 to rotate with motor 201.

[0026] In one embodiment, a sprocket 102 is mounted on one side of one of the mounting plates 101.

[0027] Specifically, such as Figure 1-3 As shown: Sprocket 102 is connected to one of the motors 201 and rotates synchronously with motor 201.

[0028] In one embodiment, one side of the motor 201 is fixedly mounted on one side of one of the mounting plates 101. The two ends of the two drive rollers 202 are respectively mounted on both sides inside the two mounting plates 101 through bearings. The output end of the motor 201 passes through the surface of the mounting plate 101 through the bearing and is connected to one side of one of the drive rollers 202. One end of the sprocket 102 passes through the surface of the mounting plate 101 through the connecting shaft and is connected to one side of the other drive roller 202. A conveyor belt 203 is sleeved on the surface of the two drive rollers 202, and a plurality of metal sheets 204 are fixedly fixed around the surface of the conveyor belt 203.

[0029] Specifically, such as Figure 1-3 As shown: Motor 201 plays a driving role, driving one of the transmission rollers 202 to rotate, and driving the conveyor belt 203 and the other transmission roller 202 to rotate synchronously. The metal sheet 204 facilitates the cutting of the electric hot knife 503.

[0030] In one embodiment, the bottoms of two mounting plates 301 are fixedly mounted on the tops of two mounting plates 101, and mounting bearings 303 are embedded on the surfaces of both mounting plates 301. Square-hole circular plates 304 are fixedly embedded inside the interiors of both mounting bearings 303. A collar 305 is fixedly mounted on one side of one of the square-hole circular plates 304, and a toothed ring 306 is fixedly mounted on one side of the collar 305. Square plates 307 are fixedly mounted on both ends of the surface of the mounting roller 302. The two square plates 307 are movably embedded inside the two square-hole circular plates 304. Threaded grooves 308 are opened on the surfaces of both ends of the mounting roller 302. Support plates 309 are fixedly mounted on the lower side of one side of both mounting plates 301, and a limit roller 310 is rotatably mounted in the middle of the two support plates 309.

[0031] Specifically, such as Figure 1-4 As shown: Mounting plate 301 provides support for the installation. Mounting roller 302 is installed within the square-hole circular plate 304 via threaded grooves 308. Mounting bearing 303 facilitates the rotation of mounting roller 302. Mounting roller 302 is fixed in place by nuts mounted on the surface of the threaded grooves 308 at both ends. Figure 3 As shown, the collar 305 does not affect the installation of the toothed ring 306 while the nut is installed. The support plate 309 supports the installation of the limiting roller 310. The limiting roller 310 limits the composite film, making it easier for it to pass under the heating device 4.

[0032] In one embodiment, the heating device 4 includes two L-shaped mounting bases 401. The opposite sides of the two L-shaped mounting bases 401 are respectively fixedly mounted on the outer sides of two mounting plates 101. Two movable grooves 402 are opened on one side of each of the two L-shaped mounting bases 401. Two springs 403 are fixedly mounted on the upper side of the other side of each of the two L-shaped mounting bases 401. An L-shaped mounting plate 404 is movably embedded in the two movable grooves 402 on one side of each of the two L-shaped mounting bases 401. An electromagnetic heating roller 405 is rotatably mounted in the middle of the two L-shaped mounting plates 404.

[0033] Specifically, such as Figure 1 , 2 As shown in Figures 3 and 5: The L-shaped mounting base 401 serves to mount the spring 403 and the L-shaped mounting plate 404. The movable groove 402 facilitates the movement of the L-shaped mounting plate 404 and also serves as a limit. The L-shaped mounting plate 404 is normally located in the middle position within the movable groove 402. When the foam base passes the bottom of the electromagnetic heating roller 405, it will push the L-shaped mounting plate 404 to rise. While avoiding damage to the foam base, it will press the composite film and the foam base together and strengthen the bonding by heating with the electromagnetic heating roller 405. The electromagnetic heating roller 405 is a common device in the prior art. Its internal structure is not described in detail.

[0034] In one embodiment, the cutting device 5 includes a U-shaped mounting base 501. The two ends of the bottom of the U-shaped mounting base 501 are respectively fixedly mounted on the top of two mounting plates 101. A hydraulic telescopic rod 502 is fixedly embedded in the top of the U-shaped mounting base 501. An electric heating knife 503 is fixedly mounted on the telescopic end of the hydraulic telescopic rod 502.

[0035] Specifically, such as Figure 1-3 As shown: The U-shaped mounting base 501 serves to install the hydraulic telescopic rod 502. The hydraulic telescopic rod 502 drives the electric heating knife 503 to cut in a regular manner through a pre-set program, so that the electric heating knife 503 lands on the surface of the metal sheet 204 each time. The electric heating knife 503 is a common device in the prior art. While cutting the composite film, it heats and adheres to both sides of the foam base.

[0036] In one embodiment, the linkage device 6 includes a double sprocket 601 and a double meshing wheel 602. The double sprocket 601 consists of two sprocket structures fixedly connected together, and the double meshing wheel 602 consists of a sprocket and a gear structure fixedly connected together. One end of the double sprocket 601 is rotatably mounted on one side of one of the mounting plates 101 via a connecting shaft, and one end of the double meshing wheel 602 is rotatably mounted on one side of one of the mounting plates 301 via a connecting shaft. A chain is fitted between the sprocket on the inner side of the surface of the double sprocket 601 and the surface of the sprocket 102. A chain is fitted between the sprocket on the outer side of the surface of the double sprocket 601 and the sprocket on the outer side of the surface of the double meshing wheel 602. The gear on the inner side of the surface of the double meshing wheel 602 meshes with the surface of the gear ring 306.

[0037] Specifically, such as Figure 2 As shown: The double sprocket 601 and the double meshing wheel 602 are common meshing wheel structures in the prior art. The inner gear of the double sprocket 601 is connected to the sprocket 102 by a chain, and the outer gear is connected to the outer gear of the double meshing wheel 602 by a chain. The inner gear of the double meshing wheel 602 meshes with the gear ring 306, so that the gear ring 306 drives the mounting bearing 303 and the square hole round plate 304 to rotate synchronously with the transmission roller 202.

[0038] Working principle: Foam base trays are regularly conveyed onto the surface of conveyor belt 203 via an external conveying device. Driven by motor 201 and drive roller 202, the conveyor belt 203 rotates, carrying the foam base trays past the bottom of the feeding device 3 and covering them with a composite film. Subsequently, the foam base trays are pressed and heated by electromagnetic heating roller 405, ensuring a tighter bond between the composite film and the foam base trays. After passing the bottom of the cutting device 5, a pre-set program is executed, and hydraulic telescopic rod 502 drives electric heating knife 503 to cut the composite film onto the metal sheet 204, completing the lamination process. This is an automated process. Operation is efficient and labor-saving. The installation roller 302 is installed by mounting the square plate 307 inside the two square hole round plates 304 and fixing it with bolts on the surface of the threaded grooves 308 at both ends. The installation roller 302 meshes with the double meshing wheel 602 through the toothed ring 306. The double meshing wheel 602 and the double sprocket 601 are driven by a chain. The double sprocket 601 and the sprocket 102 are driven by a chain. The sprocket 102 rotates synchronously with the transmission roller 202 driven by the motor 201, so that the installation roller 302 and the conveyor belt 203 rotate at the same speed, making the composite film adhere more stably to the foam base.
