[0020] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0021] like Figures 1 to 3As shown, in this embodiment, an electromagnetic induction thermal lamination system includes a frame 1, a bubble sheet feeding roller 2, a kraft paper feeding roller 3, a traction roller 4, a heating pressure roller 5, an auxiliary pressure roller 6 and a receiving roller 7. A support frame 8 is provided at the front end of the frame 1, the bubble sheet feeding roller 2 is installed on the support frame 8, the kraft paper feeding roller 3 is located at the front end of the frame 1, the heating pressure roller 5 and the auxiliary pressure roller 6 are both installed in the frame 1, the heating pressure roller 5 and the auxiliary pressure roller 6 are pressed against each other, a reflective cover 9 is provided in the middle of the frame 1, an electromagnetic induction heater 10 is fixedly installed in the reflective cover 9, the reflective cover 9 covers the heating pressure roller 5, the traction roller 4 is located between the kraft paper feeding roller 3 and the heating pressure roller 5, and the receiving roller 7 is provided at the rear end of the frame 1.

[0022] The bubble sheet feeding roller 2 rolled with bubble sheet and the kraft paper feeding roller 3 rolled with kraft paper are placed. Specifically, the bubble sheet feeding roller 2 is placed on the support frame 8 outside the frame 1, and the kraft paper feeding roller 3 is directly installed on the frame 1. The bubble sheet and kraft paper are output respectively. The traction roller 4 is responsible for providing the conveying power of the kraft paper. The electromagnetic induction heater 10 starts to generate heat after being started. After being reflected by the reflective cover 9, most of the heat is supplied to the heating pressure roller 5, so that the surface temperature of the heating pressure roller 5 increases. After the bubble sheet and the kraft paper are bonded, they pass between the heating pressure roller 5 and the auxiliary pressure roller 6. The high temperature makes the bubble sheet and the kraft paper overlap, preparing for the subsequent bubble bag cutting, and then the receiving roller 7 is responsible for rolling them up.

[0023] A front rocker arm 11 is provided between the heating pressure roller 5 and the traction roller 4 , one end of the front rocker arm 11 is swingably connected to the frame 1 , and a plurality of first pressure rollers 12 are provided on the front rocker arm 11 .

[0024] Since the feeding positions of kraft paper and bubble sheet are different, the front rocker arm 11 is added for synchronization. The kraft paper first passes through the first pressure roller 12 on the front rocker arm 11 and then is laminated with the bubble sheet. When the front rocker arm 11 swings down, it proves that the moving speed of the kraft paper is faster than that of the bubble sheet, and the rotation speed of the traction roller 4 will slow down. Conversely, when the front rocker arm 11 tilts up, it proves that the moving speed of the kraft paper is slower than that of the bubble sheet, and the rotation speed of the traction roller 4 will speed up. The purpose is to keep the conveying speed of kraft paper and bubble sheet consistent and fit perfectly.

[0025] A rear swing arm 13 is provided between the heating pressure roller 5 and the receiving roller 7 , one end of the rear swing arm 13 is swingably connected to the frame 1 , and a plurality of second pressure rollers 14 are provided on the rear swing arm 13 .

[0026] The receiving roller 7 is driven to rotate by a power source, and the moving speed of the bubble bag sheet heat-laminated between the heating pressure roller 5 and the auxiliary pressure roller 6 may be faster or slower than the rotation speed of the receiving roller 7. The rear swing arm 13 and the second pressure roller 14 located on the rear swing arm 13 are additionally provided, and the bubble bag sheet after heat lamination passes through the second pressure roller 14 and is then rolled up by the receiving roller 7. When the rear swing arm 13 swings down, it proves that the moving speed of the bubble bag sheet is faster than the rotation speed of the receiving roller 7, and the rotation speed of the heating pressure roller 5 will slow down. Conversely, when the rear swing arm 13 tilts up, it proves that the moving speed of the bubble bag sheet is slower than the rotation speed of the receiving roller 7, and the rotation speed of the heating pressure roller 5 will speed up.

[0027] Specifically, a pressure roller motor 15 is disposed on one side of the frame 1 , and a driving end of the pressure roller motor 15 is transmission-connected to one end of the heating pressure roller 5 .

[0028] A traction motor 16 is disposed on one side of the frame 1 , and a driving end of the traction motor 16 is transmission-connected to one end of the traction roller 4 .

[0029] The pressure roller motor 15 controls the rotation speed of the heating pressure roller 5 , and the traction motor 16 controls the rotation speed of the traction roller 4 , so that the overall operation process is controlled and stable.

[0030] The frame 1 is provided with a creasing frame 17 , which is swingably connected to the frame 1 , and a pressing wheel 18 is provided in the middle of the creasing frame 17 .

[0031] In addition, an indentation cylinder 19 is installed on the indentation frame 17 , and the pressing wheel 18 is connected to the driving end of the indentation cylinder 19 .

[0032] The creasing frame 17 is installed on the frame 1, and the creasing frame 17 swings at a certain angle, and then the creasing cylinder 19 extends out of the driving end, forcing the pressing wheel 18 to press a creasing on the bubble bag sheet, which is convenient for subsequent production.

[0033] It should be stated that the above-mentioned specific implementation methods are only preferred embodiments of the present invention and the technical principles used. Within the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of by technicians familiar with this technical field should be included in the protection scope of the present invention.
