Laminating device of die cutting machine

Abstract

The invention discloses a laminating device of a die cutting machine. A film guiding roller device comprises film guiding roller upper side plates, a first film guiding roller shaft, a second film guiding roller shaft, a first film guiding roller, a second film guiding roller, a tension air bellow and a draught fan. The film guiding roller upper side plates are oppositely arranged. The first filmguiding roller shaft and the second film guiding roller shaft are sequentially arranged between the film guiding roller upper side plates. The two ends of the first film guiding roller shaft and the two ends of the second film guiding roller shaft are connected with the film guiding roller upper side plates through bolts. The first film guiding roller and the second film guiding roller are correspondingly in cup joint to the first film guiding roller shaft and the second film guiding roller shaft through bearings. An interval is reserved between the first film guiding roller and the second film guiding roller. The tension air bellow is arranged under the interval between the first film guiding roller and the second film guiding roller. The draught fan is arranged at the lower end of the tension air bellow. The wind direction of the draught fan acts on the interval between the first film guiding roller and the second film guiding roller. The draught fan and the tension air bellow applydownward pressure to a laminating material, constant tension of the laminating material is guaranteed, and main material bending and deforming after laminating and combining are avoided.

Description

technical field [0001] The invention relates to the field of die-cutting machines, in particular to a film covering device of a die-cutting machine. Background technique [0002] The die-cutting machine is mainly the main equipment for printing and paper packaging. The working principle of the die-cutting machine is to use the template carved by steel knife, metal mold, steel wire or steel plate, and apply a certain pressure through the embossing plate to convert the printed matter or cardboard Cut into certain shapes. The main parts of the die-cutting machine are the die-cutting platen and the press-cutting mechanism. Among them, the working principle of the die-cutting device is: the die-cutting work is completed under the action of pressure. Simply speaking, the die-cutting pressure is controlled by the movable platform. The press fit with the upper fixed platform takes place. [0003] However, since the paper feeding mode of the die-cutting machine is one stop and one ...

Problems solved by technology

[0003] However, since the paper feeding mode of the die-cutting machine is one stop and one stop, it will have an impact on the material. When the film lamination process is required, because the material thickness of the film itself is very thin, it is easy to cause the film to be stretched. The shrinkage of the back film will deform and bend the main material, resulting in the occurrence of defective products
