Description

Technical Field

[0001] This utility model relates to the field of improved design technology of mask machines, and in particular to a fully automatic single-layer cup-shaped mask machine. Background Technology

[0002] The production process of cup-shaped masks mainly includes mask body forming and nose wire and ear loop fixing. Conventional mask machines first form the mask body and then transfer it to the nailing device. Then, the cut ear loop ends are placed manually at the two nailing positions on the mask body. The nailing device then works to fix the ear loops to the mask body. Finally, the finished mask is taken out. The structure used for ear loop nailing and fixing in the above-mentioned device is complex. The nailing method may have problems such as ventilation holes, poor comfort, or lower production efficiency than welding. It also does not involve the ear loop conveying and welding fixing structure.

[0003] In the prior art, patent CN213798141U discloses a cup-shaped mask machine, including a mask body conveying device, a nose wire welding device, a nose wire pressing device, a pad printing device, an ear loop fastening device, an O-ring welding device, a punching device, a breathing valve mounting device, and a material discharge device. The ear loop fastening device includes a fastening frame, an ear loop supply mechanism mounted on the fastening frame, a fastening mechanism mounted on the fastening frame, an ear loop clamping robot located on one side of the fastening mechanism, and an ear loop cutting device located below the ear loop clamping robot. The ear loop cutting device is used to cut the ear loop material strip supplied by the ear loop supply mechanism to form ear loops. The ear loop clamping robot is used to clamp both ends of the ear loop and transport the ear loop to the bottom of the fastening mechanism. This utility model automatically realizes the production of masks with breathing valves, with high production efficiency. Moreover, by fastening the ear loops to the mask body, the connection between the ear loops and the mask body is stable, resulting in high-quality masks.

[0004] In order to solve one of the above problems, this application provides a fully automatic single-layer cup-shaped mask machine. Utility Model Content
