Description

Technical Field

[0002] The laminating machine is an auxiliary machine of the die-cutting machine. The die-cutting process production line mainly includes die-cutting material laminating, laminating material flat-pressing die-cutting and die-cutting material film cutting. When producing die-cut products, different die-cutting materials to be processed need to be placed on the input end of the laminating machine respectively. Through the action of the laminating machine, the different die-cutting materials to be processed are laminated to each other and output from the output end of the laminating machine. Then the laminated die-cutting materials are input into the flat-pressing die-cutting machine for flat-pressing die-cutting, and finally cut into the required specifications and sizes through the cutting machine.

[0003] like Figure 1 As shown, the laminating components of the existing three-seat laminating machine generally include a laminating feed frame assembly 100, three sets of laminating seat assemblies 200, and a laminating transition frame assembly 300 disposed between the laminating seat assemblies 200. In the working process of the laminating machine, waste discharge, laminating, and winding are three important steps. During the laminating step, if the die-cutting material to be laminated itself is not sticky, or requires a stronger adhesive force, then in order to ensure that different material layers can be firmly bonded together, glue or other adhesives may need to be used. The gluing structure adopted by the existing three-seat laminating machine is: a connecting shaft perpendicular to the feeding direction is installed on the laminating transition frame assembly 300, and then a brush roller is rotatably arranged on the connecting shaft, and the glue is evenly applied to the material to be bonded by the brush roller. The disadvantages of this gluing structure are: when applying glue, it is necessary to manually add glue to the brush roller, and the brush roller cannot continuously provide glue for a long time; the brush roller is not convenient to disassemble, and it is not convenient to replace brush rollers of different lengths for die-cutting materials to be processed with different widths.
