Ultrasonic cut-off mechanism of ear ribbons and nose bridge bars of full-server masks

Abstract

The invention provides an ultrasonic cut-off mechanism of ear ribbons and nose bridge bars of full-server masks, and belongs to the field of mask processing. The mechanism comprises an ultrasonic cutting mechanism, a cutter supporting mechanism is fixedly supported at the bottom of the ultrasonic cutting mechanism, transport mechanisms are fixedly mounted at the four corners of the bottom of the cutter supporting mechanism, and a traction mechanism is fixedly arranged in the middle of the bottom end of the ultrasonic cutting mechanism. The ultrasonic cutting mechanism, a machine body, an ultrasonic generator and an ultrasonic amplitude-change pole are arranged, so that high-intensity ultrasonic cutting energy is conveniently generated at the cutting end, and the energy is converted into high-frequency ultrasonic vibration under the action of a transducer so as to be transmitted to the ultrasonic amplitude-change pole; and then the high-frequency ultrasonic vibration is transmitted to an ultrasonic cutter through the ultrasonic amplitude-change pole, and due to the high-frequency vibration generated at the ultrasonic cutter, when the to-be-cut ear ribbons make contact with the nosebridge bars, the ultrasonic cutting aim is achieved.

Description

technical field [0001] The invention belongs to the technical field of mask processing, and in particular relates to an ultrasonic cutting mechanism for ear hooks and nose wires for full-servo masks. Background technique [0002] 1) In the existing mask production process, it is not convenient to ultrasonically cut the ear loops and nose wires in the mask production process. The traditional manual cutting process is cumbersome and cannot improve the stability of the cutting process. The existing cutting process is inconvenient. Carry out assembly line cutting production, the traditional cutting efficiency is low, unable to support a huge production supply chain; [0003] 2) The cutting section in the existing manual cutting process is relatively rough, and the thread end is easy to pill and collapse when cutting, which seriously affects the overall quality of the mask in the subsequent production process. During the subsequent wearing process, the mask that is attached to th...
