An arcuate nose bridge strip cutting unit

Abstract

This utility model discloses a nose bridge strip processing technology, specifically a curved nose bridge strip cutting assembly, including a connecting frame. A mounting frame and a fixing frame are respectively connected to the top and bottom of the connecting frame. A connecting plate is provided on the top of the connecting frame, and multiple sets of wire guide wheels are rotatably connected to the connecting plate. A conveying wheel is rotatably connected inside the fixing frame, and the conveying wheel and the wire guide wheel are correspondingly arranged. A conveying component is connected to the connecting frame to convey the nose bridge strip. A cutting component is connected to the top of the connecting frame to cut the nose bridge strip conveyed by the conveying component. A motor drives a drive gear to rotate, which in turn drives a driven gear that is in transmission with the drive gear to rotate, causing the pulling wheel to work synchronously. This pull wheel, in conjunction with the wire guide wheel and the conveying wheel, assists in conveying the nose bridge strip. After the strip is conveyed to the correct position, the cutting motor drives a swing arm to deflect, causing the slide to slide along the outside of the guide seat, thus changing the position of the cutting blade and performing the nose bridge strip cutting operation.

Description

Technical Field

[0001] This utility model relates to the field of nose bridge strip processing technology, specifically to a curved nose bridge strip cutting assembly. Background Technology

[0002] A face mask is a hygiene product, generally worn over the mouth and nose to filter the air entering the mouth and nose. To ensure a better fit, most face masks on the market have a nose bridge strip installed.

[0003] Before the nose bridge strip is attached to the mask, it needs to be cut into strips of equal length from a roll. This action is usually done manually, which is inefficient and prone to large deviations in length. Therefore, there is an urgent need to provide a curved nose bridge strip cutting assembly. Utility Model Content
