[0002] Food cover film, i.e. composite plastic cover film for food packaging, is a material widely used in food packaging. This material is mainly used as a composite film for sealing food containers with plastic as the heat-sealing layer. It is classified according to the conditions of use, heat-sealing strength with the container, water vapor permeability, oxygen permeability, etc. For example, it is divided into ordinary grade, boiling grade, semi-high temperature cooking grade and high temperature cooking grade according to the conditions of use. The food cover film die-cutting device is a special equipment used in the field of food packaging. It is mainly used for the production of easy-to-peel cover films. The main function of these devices is to efficiently and accurately die-cut food packaging films to meet different types of packaging needs.

[0003] However, the existing customized die-cutting devices for food cover films have the following problems: When the food cover film is die-cut, a large amount of dust and impurities may adhere to the surface of the food cover film raw materials during the production and processing. These dust and impurities will remain on the upper and lower surfaces of the food cover film after the die-cutting of the food cover film is completed, thereby reducing the production and processing quality of the food cover film and affecting its subsequent use. In addition, during the die-cutting process, the food cover film may be wrinkled, which will also greatly affect its subsequent use after the die-cutting process and affect its aesthetics.

[0027] like Figure 7As shown, the dust collecting structure 10 includes an exhaust fan 1001, a dust collecting box 1002, a dust collecting pipe 1003, a mounting plate 1004 and a dust collecting cover 1005. The exhaust end of the exhaust fan 1001 is connected to one side of the dust collecting box 1002. A box door 1006 is hingedly connected to one side of the dust collecting box 1002. The box door 1006 is sealedly connected to the dust collecting box 1002 when closed. A filter plate 1007 is installed in the internal movable card of the dust collecting box 1002. One end of the dust collecting pipe 1003 is connected to the side of the dust collecting box 1002 away from the exhaust fan 1001. The dust collecting pipe 1003 passes through the mounting plate 1004 and is fixedly connected to the mounting plate 1004. The dust collecting cover 1005 is fixed to one end of the dust collecting pipe 1003. The fixed connection allows the exhaust fan 1001 to work in conjunction with the dust box 1002 and the dust pipe 1003 to generate suction at the dust hood 1005, thereby sucking the floating dust and impurities generated by the cleaning work into the dust box 1002, where they are intercepted and filtered by the filter plate 1007, leaving the dust and impurities in the dust box 1002, and the clean air is discharged through the air outlet of the exhaust fan 1001. Subsequently, the box door 1006 can be opened to centrally clean the dust and impurities inside the dust box 1002, thereby effectively preventing the dust and impurities from attaching to the raw materials of the food cover film for the second time and effectively preventing the dust and impurities from endangering the health of nearby workers.

[0028] The exhaust fan 1001 and the dust box 1002 are both fixedly installed on the top of the first mounting frame 801, the mounting plate 1004 is fixedly installed on one side of the first mounting frame 801, and the dust hood 1005 faces the cleaning roller 802, so that the dust hood 1005 can better extract dust and impurities.

[0029] Working principle: During operation, the food cover film raw material roll is put on the unwinding mechanism 4, and one end of the roll is passed through the two cleaning rollers 802, then through the first caressing plate 903 and the second caressing plate 908, and then through the upper surface of the supporting seat 2, and finally wound and fixed on the rewinding mechanism 5. At this time, the two cleaning rollers 802 can be driven to rotate by the driving motor 804, in cooperation with the two pulleys 805 and the transmission belt 806. When the two cleaning rollers 802 rotate, they can cooperate with the soft bristles arranged on the outside to clean the dust and impurities on the upper and lower surfaces of the cover film raw material passing between the two cleaning rollers 802, so as to avoid the subsequent die-cutting of the cover film. After processing, a large amount of dust and impurities are still attached to the surface, which affects the production and processing quality of the food cover film. At the same time, the movable plate 905 can be driven downward by the extension and contraction of the cylinder 904, so as to adjust the distance between the second caressing plate 908 and the first caressing plate 903. When the bottom of the first caressing plate 903 abuts against the top of the food cover film raw material, the movable plate 905 continues to move downward until the first caressing plate 903 abuts against the second caressing plate 908 through the food cover film. At this time, multiple spring sheets 906 are compressed to apply a downward elastic force to the second caressing plate 908 to ensure that when the food cover film raw material passes between the first caressing plate 903 and the second caressing plate 908, the upper surface of the food cover film The lower surface can be elastically pressed against the first smoothing plate 903 and the second smoothing plate 908 respectively, so as to improve the smoothing effect. When the food cover film raw material passes between the two cleaning rollers 802, the dust and impurities on the upper and lower surfaces of the food cover film can be cleaned and processed by the two rotating cleaning rollers 802. When the food cover film passes between the first smoothing plate 903 and the second smoothing plate 908, the first smoothing plate 903 and the second smoothing plate 908 can be used to smooth the food cover film well, so as to avoid wrinkles on the food cover film and affect the subsequent die-cutting quality and the aesthetics after die-cutting. In this process, the exhaust fan 100 can also be used to 1, in cooperation with the dust collecting box 1002 and the dust collecting pipe 1003, suction is generated at the dust collecting cover 1005, so that the floating dust impurities generated by the cleaning work are sucked into the dust collecting box 1002, and are intercepted and filtered by the filter plate 1007, leaving the dust impurities in the dust collecting box 1002, and the clean air is discharged through the air outlet end of the exhaust fan 1001, and then the box door 1006 is opened to centrally clean the dust impurities inside the dust collecting box 1002, so that it is not only effective to prevent the dust impurities from attaching to the raw materials of the food cover film for a second time, but also to effectively prevent the dust impurities from endangering the health of nearby workers.
