Referring to fig. 10, the mask sheet discharging device 8 includes a bottom frame 81, a conveyor belt 82, an ejecting roller mechanism 83 and a nip roller mechanism 84, the conveyor belt 82 is mounted on the bottom frame 81, the ejecting roller mechanism 83 is disposed across the front end of the conveyor belt 82 and in front of the nip roller mechanism 84, the nip roller mechanism 84 and the ejecting roller mechanism 83 are spaced apart in the front-rear direction, and the nip roller mechanism 84 is attached to the conveying surface of the conveyor belt 82 in a manner of being spanned. The conveyor belt 82 drives the pinch roller mechanism 84 in a rotational motion.

Referring to fig. 11, the ejecting roller mechanism 83 includes a first sheet metal part 831, a first roller 832 and a first sleeve 833, two ends of the first roller 832 are respectively installed on the conveying belt 82 through the first sheet metal part 831, the first sleeve 832 is sleeved on the first roller, and the sleeve is used for ejecting the mask sheet from the mask sheet belt.

The first roller 832 comprises a fixed shaft and a second sleeve, two ends of the fixed shaft are respectively installed on the conveying belt 82 through a second sheet metal part 841, and the second sleeve is rotatably sleeved outside the fixed shaft.

Referring to fig. 12, the nip roller mechanism 84 includes a second sheet metal component 841 and a second roller 842, two ends of the second roller 842 are respectively mounted on the conveyor belt 82 through the second sheet metal component 841, the outer peripheral wall of the second roller 842 is pressed on the conveyor belt 82, and the conveyor belt 82 drives the second roller 842 to rotate.

Referring to fig. 12, the second sheet metal part 841 is in a barb shape, a long circular hole 8411 is formed in the second sheet metal part 841, and the end of the second roller 842 is inserted into the long circular hole 8411 and can rotate.

The working principle of the mask sheet discharging device 8 is as follows:

the mask sheet material band cut by the mask sheet cutting device 7 bypasses the lower parts of the first roller 832 and the first sleeve 833 along the oblique rear lower part and then bypasses the rear parts of the first roller 832 and the first sleeve 833, the outer diameter of the first sleeve 833 is larger than that of the first roller 832, in the process, the mask sheet on the mask sheet strip is extruded by the first sleeve 833 and then ejected out of the mask sheet strip, the mask sheet is then inserted between the second roller 842 and the conveying belt 82, the second roller 842 presses the mask sheet on the conveying belt 82 through self weight to increase the friction force between the mask sheet and the conveying belt 82, the conveying belt 82 drives the mask sheet to move backwards through the friction force to completely separate the mask sheet from the mask sheet strip, and finally, the mask sheet discharging work is finished, the mask sheet strip of the mask sheet to be taken out is a waste strip which moves forwards along the oblique front upper direction and is finally wound on the waste strip recycling device 9.

The waste material belt recovery device 9 comprises an air expansion shaft and a first rotary driving mechanism, the air expansion shaft is installed on the first rotary driving mechanism, the first rotary driving mechanism drives the air expansion shaft to do rotary motion, and the waste material belt is wound outside the air expansion shaft.

Still include gauze mask sheet strip drive arrangement 10, it is used for the motion of auxiliary drive gauze mask sheet strip, and gauze mask sheet strip drive arrangement 10 is installed on lower frame 3 and is located between gauze mask strap welding set 6 and the gauze mask cutting device.

The mask sheet material belt driving device 10 comprises an upper rubber coating roller, a lower rubber coating roller, a roller seat and a second rotary driving mechanism, wherein the upper rubber coating roller and the lower rubber coating roller can be rotatably connected in the roller seat, the upper rubber coating roller is pressed on the lower rubber coating roller, the right end of the upper rubber coating roller or the lower rubber coating roller extends rightwards out of the roller seat and is in driving connection with the second rotary driving mechanism, and the second rotary driving mechanism drives the upper rubber coating roller or the lower rubber coating roller to do rotary motion so as to drive the mask sheet material belt passing between the upper rubber coating roller and the lower rubber coating roller to move.

The technical scope of the present invention is not limited to the above embodiments, and any modifications, equivalent variations and modifications made to the above embodiments according to the technical spirit of the present invention still fall within the technical scope of the present invention.
