Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] This detailed implementation manner is a film laminating device for sheets, and its structural schematic diagram is as shown in Figure 1 、 Figure 2 It includes a bearing table 7, a pressing belt 4, a support frame 5 and a heating roller 12. The inner side of the bearing table 7 has a conveying cavity for the sheet and the film to pass through. Inside the conveying cavity, a plurality of clamping rods 3 are arranged symmetrically in pairs, and a pressing belt 4 is arranged between the clamping rods 3. The pressing belt 4 and the clamping rods 3 are arranged in a corresponding upper and lower double-layer manner. The support frame 5 is arranged on the opposite side of the two pressing belts 4, and the support frame 5 is fixedly connected to the surface of the bearing table 7. The upper surface and the bottom end surface of the bearing table 7 are both convexly provided with driving blocks 8. The inside of the driving blocks 8 is hollow, and a motor is fixedly embedded. A driving shaft 9 is rotatably installed between the driving blocks 8. The driving shaft 9 is connected to the output shaft of the motor, and a film roll 1 is installed on the driving shaft 9. The film rolls 1 are arranged symmetrically at upper and lower intervals.

[0024] Referring to Figure 3 , the surface of the support frame 5 facing the pressing belt 4 is provided with a hollow, and a plurality of heating rollers 12 are fixedly embedded in the hollow. The plurality of heating rollers 12 are arranged side by side at intervals, and the heating rollers 12 are rotatably connected to the support frame 5. A plurality of rotating rollers are arranged inside the pressing belt 4, and a second motor 6 for driving the rotating rollers to rotate is fixedly installed on the outer wall of the bearing table 7.

[0025] Referring to Figure 2 、 Figure 4, the inner wall of the carrier table 7 has a perforation 14, and the end of the clamping rod 3 passes through and extends into the interior of the carrier table 7. A transmission gear 13 is fixedly connected to the end of the clamping rod 3, and the clamping rods 3 symmetrically distributed up and down are engaged with each other through the transmission gear 13. A sprocket 10 is fixedly connected to the end of the clamping rod 3 away from the transmission gear 13, and the sprocket 10 penetrates into the interior of the carrier table 7. Multiple groups of sprockets 10 are spaced apart inside the carrier table 7, and a drive chain 11 is connected between the multiple groups of sprockets 10. A first motor 2 fixed to the sprocket 10 is installed on the outer wall of the carrier table 7. When the drive chain 11 rotates, all the multiple groups of sprockets 10 rotate, and thus the clamping rod 3 inside the carrier table 7 has a rotational force to quickly convey the sheet material and the film.

[0026] Working principle: When in use, first place the sheet material to be laminated into the carrier table 7 from the direction of the film roll 1, and clamp it with the clamping rods 3 distributed at intervals in the upper and lower layers. The first motor 2 is started to drive the sprocket 10 to rotate. A drive chain 11 is sleeved outside the sprocket 10. When the drive chain 11 rotates, all the multiple groups of sprockets 10 rotate, and thus the clamping rod 3 inside the carrier table 7 has a rotational force. At this time, the motor inside the drive block 8 is also started synchronously, and the drive shaft 9 rotates. The film roll 1 releases on both the upper and lower sides of the sheet material. After the film and the sheet material enter between the clamping rods 3, they are pressed against each other under force. The upper clamping rod 3 is the power source and is driven through the cooperation of the drive gear at the end. The clamping rods 3 in the upper and lower layers rotate relative to each other to convey the sheet material. The film and the sheet material are synchronously conveyed into the pressing belt 4, and the pressing belt 4 presses the whole surface. Compared with the conveying pressure of the clamping rod 3, the overall contact surface of the pressing belt 4 is larger, so that the pressing force between the film and the sheet material is higher. Then start the heating roller 12, and the heat generated by the heating roller 12 warms the pressing belt 4, so that the film begins to soften under the influence of high temperature and has a higher degree of fit with the sheet material, and can be more tightly connected after cooling.

[0027] All the technical features in this embodiment can be freely combined according to actual needs.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
