Technical Field

[0001] The utility model relates to the technical field of laminating machines, in particular to a hot pressing laminating machine. Background Art

[0002] The hot press laminator is a widely used pre-coating laminator in China. Its operating principle is to first apply adhesive to the plastic film using a roller coating device. The film is then softened by heating with a hot press roller. The printed material, coated with primer, is then pressed together with the film to form a laminated product that combines paper and plastic. Since adhesive coating and drying are unnecessary, the machine is compact, small, low-cost, and easy to operate. It is widely used in photo agencies, printing factories, advertising, design, and self-adhesive labeling.

During the replacement, a series of operations such as film application and mold insertion are required before the machine can be started. The whole process takes a long time, which affects the efficiency of hot pressing laminating. Utility Model Content

The model of the distance measuring sensor 4 is KJT-TLS-30C-E1, which has high detection accuracy.

[0023] T-slots 12 are provided on the inner walls on both sides of the frame 1, and pneumatic blocks are installed inside the two T-slots 12. The four pneumatic blocks all include a cylinder 7, and the cylinder 7 is fixedly installed on the inner wall of the T-slot 12. The movable end of the cylinder 7 is fixedly connected to the mounting block 11 that is slidably connected to the T-slot 12. The T-slot 12 has a limiting effect on the mounting block 11, and can package the stability of one end of the mounting block 11.

[0024] A heating roller is connected to the two pneumatic blocks on the same side for rotation. Both heating rollers include a roller body 5, and the roller body 5 is rotationally connected to two adjacent mounting blocks 11. A plurality of heating wires 13 are fixedly installed inside the roller body 5. The heating wires 13 can heat the roller body 5, thereby heating the passing film.

[0025] The two pneumatic blocks located in the same T-slot 12 are jointly installed with a rotating assembly between the adjacent heating rollers. The two rotating assemblies include a drive motor 16, and the drive motor 16 is fixedly embedded in the outer wall of the adjacent mounting block 11. The driving end of the drive motor 16 is fixedly connected to the first gear 15, and the outer surface of the first gear 15 is meshed with the second gear 17, and the mounting shaft of the second gear 17 passes through the adjacent mounting block 11 and is fixedly connected to the adjacent roller body 5. The drive motor 16 drives the first gear 15 to rotate, and can drive the roller body 5 to rotate through the second gear 17. The two roller bodies 5 rotate in opposite directions, which is convenient for compacting and conveying the film.

[0026] A vacuum adsorption assembly is installed between a single T-slot 12 and the two heating rollers. The vacuum adsorption assembly includes a vacuum pump 8. The vacuum pump 8 is the core of the vacuum adsorption assembly, which is conducive to the operation of the vacuum adsorption assembly. The vacuum pump 8 is fixedly installed on the inner top of the adjacent T-slot 12. The air inlet of the vacuum pump 8 is fixedly penetrated by a connecting pipe 9. Two hoses 10 are symmetrically fixedly penetrated at the bottom of the connecting pipe 9, and the hoses 10 and the roller body 5 are sealed and rotated. The vacuum adsorption assembly also includes a plurality of through holes 14 opened on the outer wall of the roller body 5, and the plurality of through holes 14 are designed in a straight line, which is convenient for adsorbing and fixing one end of the unused film. The connection between the two hoses 10 and the connecting pipe 9 is installed with an electromagnetic valve. The opening and closing of the connection between the hose 10 and the connecting pipe 9 can be controlled by the set solenoid valve.

[0027] Working principle: First, install the film on one of the unwinding rollers 3, and then perform the laminating operation. During the hot pressing laminating process, the spare film can be installed on the other unwinding roller 3, and then one end of the film can be passed through the roller body 5. Then the vacuum pump 8 is operated, and the roller body 5 on this side is vacuumed through the connecting pipe 9 and the hose 10. Then the film is adsorbed on the roller body 5 on this side through the through hole 14, and then the vacuum pump 8 stops running. When the distance sensor 4 detects that the film on the unwinding roller 3 placed for the first time is about to run out, the two cylinders 7 on the same side are operated, and the roller body 5 adsorbed with the film is pushed to fit the other roller body 5 through the mounting block 11 until the two films fit together, and at the same time the heating wire 1 3 runs synchronously with the rotating assembly, the heating wire 13 heats the film, the driving motor 16 drives the first gear 15 to rotate, and then drives the roller body 5 to rotate through the second gear 17. The two roller bodies 5 rotate relative to each other to compress and transport the two films. At the same time, the other hose 10 is connected to the connecting pipe 9 through the electromagnetic valve, so that air can pass through the roller body 5 where the film is adsorbed, thereby releasing the adsorption. After the two films are pressed together, they enter the hot pressing roller for hot pressing and laminating. At this time, waste samples can be put in to facilitate hot pressing of the membrane joint on the waste sample. When the end of the initial film passes through the roller body 5, the roller body 5 on this side is reset, and the heating wire 13 and the rotating assembly both stop running.
