[0054] A control box is installed on the frame of the invention. A control system and a touch screen are arranged in the control box. A PLC program is embedded in the control system. The operation of the whole device is controlled by the PIC program.

[0055] The edge material recovery mechanism of the present invention is a fan, and the edge material is recovered by the suction force of the fan.

[0056] The surfaces of the upper roller body and the lower roller body of the present invention are engraved with patterns, and the mask material is side-sealed, circumferentially sealed, and circumferentially cut through the patterns.

[0057] When the present invention is used, first, the operating program of the mask machine is set through the touch screen, the speed of the servo motor is controlled, and the air expansion shaft rotates to realize the material discharge operation of the meltblown cloth roll, the ear hanging layer material roll, the outer layer material roll, and the lining material roll. At the same time, the side sealing roller transmission mechanism, the smooth pressing roller mechanism, the peripheral sealing roller transmission mechanism, the peripheral cutting roller transmission mechanism, the wind bucket component one, the wind bucket component two, the wind bucket component three, the edge material recovery mechanism, the traction wheel combination one, the cutting device, and the traction wheel combination two work.

[0058] At the same time, the meltblown cloth runs to the traction wheel assembly 2 through the material exchange device 1, the swing arm assembly 1, and the deviation corrector 1;

[0059] At the same time, the hanging ear layer material is moved to the traction wheel assembly 2 through the material exchange device 2, the swing arm assembly 2, the traction wheel assembly 1, the deviation corrector 2, the cutting device, the material distribution bracket, and the deviation corrector 3;

The folded and flattened mask material is circumferentially embossed by the circumferential sealing roller transmission mechanism. The circumferentially embossed mask material is finally circumferentially cut and shaped by the circumferential cutting roller transmission mechanism. The edge materials are uniformly recovered by the edge material recovery mechanism, and the finished products are directly disinfected and packaged.

[0063] During the process of making masks from mask materials, the wind bucket assembly works, and the suction force generated by the wind bucket makes the mask material move on the conveyor belt, effectively preventing the mask material from deviating during the movement.

[0064] When the meltblown cloth roll, ear layer material roll, outer layer material roll and lining material roll are about to run out, the material switching device works, and the cylinder 1 on one side of the material switching device pushes the upper splint on one side to squeeze the switching material onto the middle plate. At the same time, the cylinder 1 on the other side pushes the upper splint on one side to squeeze the mask material that is about to run out onto the middle plate. Then, the two cylinders 2 work synchronously to push the two lower splints toward the middle, so that the two rolls of material are in contact and fixed (usually double-sided tape is pasted on both sides of the spare material, and the fixation is completed by the action of the double-sided tape). Then, the blade is pushed by the action of cylinder 1 to cut off the mask material that is about to be used up, thereby realizing the automatic material switching operation.

[0065] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
