[0040] Furthermore, the unwinding mechanism 1 includes a material roll and an inflation shaft.

[0041] The material roll is fixed on the inflation shaft. When the mask machine is working, the ear band material of the material roll passes through the material exchange device and the swing rod assembly in turn, and then is folded through the three-fold folding mechanism. The folded ear band material part is then dotted by the dotting and fixing mechanism to fix the folded part. The ear band material after dotting and fixing is placed in the deviation corrector, and the position is adjusted by the deviation corrector. The adjusted ear band material enters the glue dispensing machine and is glued by the glue dispensing machine. The glued ear band material passes through the wind bucket assembly and enters the ear band slitting mechanism. The ear band material is cut by the ear band cutting mechanism to form a strip ear band 51. At the same time, the negative pressure generated by the surface of the lower knife wheel makes the ear band adhere to the surface of the lower knife wheel. The ear band moves with the rotation of the lower knife wheel. When it moves to the upper end of the second wind bucket component, the ear band is adsorbed from the lower knife wheel to the mask body 52 at the upper end of the second conveyor belt of the second wind bucket component by the higher level negative pressure of the second wind bucket component. Finally, the ear band moves with the ear band body to the ear band pressure point mechanism, and the fixed connection between the ear band and the mask body is completed by the action of hot pressing.

[0042] One end of the fixed shaft 2 and the fixed shaft 4 of the present invention are both connected to the servo motor.

[0043] When the ear band of the present invention is cut, the fixed shaft four drives the gear three to rotate through the action of the gear five, so that the lower cutter wheel and the upper cutter wheel rotate synchronously, and the slicing work of the ear band material is completed through the cooperation of the cutting blade on the upper cutter wheel and the lower cutter wheel. The sliced ​​ear band is directly driven by the lower cutter wheel to the conveyor belt two.

[0044] The material discharge mechanism, material exchange device, swing arm assembly, three-fold wrinkle mechanism, deviation corrector, glue dispenser, and air bucket assembly of the present invention are all conventional structures, so they are not described in detail.

[0045] The material changing device of the present invention is mainly used for switching between material rolls to realize material changing operation without stopping the machine.

[0046] The swing rod assembly of the present invention is mainly used for tensioning ear strap materials.

[0047] The ear band main body of the present invention is a general term for other materials for making the ear band. When the mask machine runs to the fixation of the ear band, the other materials for making the mask are moved to this point and the fixed connection is completed.

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.
