In order to save the using steps when the mask is applied, the film tearing operation is carried out on the aluminum strip to be processed at the moment. The film tearing operation is an operation of tearing the protective film on one side surface of the aluminum strip to be processed from the main body of the aluminum strip to be processed by using a film tearing machine, and it should be understood that the main body herein and the main body mentioned hereinafter refer to the aluminum material itself, i.e., the aluminum strip not including other substances such as the protective film.

After the film tearing operation is completed, the single-side film aluminum strip is obtained, namely, only one side of the aluminum strip is provided with the protective film, then the gluing operation needs to be carried out on the side surface of the single-side film aluminum strip which is not covered with the film, namely, glue for pasting the aluminum strip on the mask cloth layer is smeared on the side surface of the single-side film aluminum strip which is not covered with the film, and after the gluing operation is completed, the glued aluminum strip is obtained. It can be understood that the aluminum strip is subjected to the gluing operation, so that the steps of finally attaching the aluminum strip to the mask cloth layer are reduced.

And finally, rolling the glued aluminum strip towards the side coated with the glue, and obtaining an aluminum strip roll after the rolling operation is completed. The aluminum strip coil can be used as a standard part and supplied to a mask manufacturing place, and the protective film can always protect the aluminum strip in the transportation process, so that the aluminum strip applied to the mask can be well cleaned. And through the operation of tearing the membrane in advance, the rubber coating operation, then effectively reduced the use step of aluminium strip for the gauze mask, and then improved the production rate of gauze mask.

The film winding drum 200 is connected to the frame 100 and can rotate around the frame 100, and the film winding drum 200 is used for winding the film. The driving unit 300 is fixed to the frame 100, an output end of the driving unit 300 is fixed to the film winding drum 200, and the driving unit 300 is configured to rotate the film winding drum 200 with respect to the frame 100.

Specifically, as shown in fig. 3, the frame 100 is used to provide support for the film winding drum 200 and the driving part 300, and the film winding drum 200 is cylindrical, and the drum shaft thereof is inserted into a through hole of the frame 100 through a bearing or directly, so that the film winding drum 200 can be rotated in a fixed axis manner relative to the frame 100. The driving portion 300 may be a simple motor, or a belt transmission structure driven by a motor, and the output end of the driving portion 300 is fixed at one end of the shaft of the film winding drum 200, so that the driving portion 300 can drive the film winding drum 200 to rotate.

The film tearing machine further comprises a winding roller, the direction of the cylinder shaft of the winding roller is the same as that of the film rolling roller 200, and the winding roller can be fixed on the rack 100 or arranged on a support frame at a certain distance from the rack 100.

In a specific using process, a worker firstly winds the aluminum strip to be processed, and the axis direction of the wound aluminum strip to be processed is the same as the cylinder shaft direction of the winding roller. Then fix an end of treating processing aluminium strip of rolling at the tube side of rolling cylinder for when rolling cylinder rotated, the aluminium strip of having torn the protection film can twine on rolling cylinder, and the side that does not tectorial membrane this moment of aluminium strip can be towards the tube side of rolling cylinder.

The film rolling roller 200 is arranged between the rolled aluminum strip to be processed and the rolling roller, the side face of the aluminum strip to be processed, which needs to be subjected to film tearing, faces the film rolling roller 200, a worker needs to manually tear off a protective film from one section, and the protective film is fixed on the surface of the film rolling roller 200.
