Mask ear loop line stretching swing arm

Abstract

The invention relates to a mask ear loop line stretching swing arm. A servo motor is vertically installed at the top of a lifting support; a rotating shaft is in butt joint with an output port in thebottom of the servo motor; the top of the rotating shaft is in transmission butt joint with a sleeve shaft installed at the top of a bearing pedestal; and the bottom of the bearing pedestal is in buttjoint with an output port of an air cylinder through a second transmission rod; the upper end and the lower end of the sleeve shaft are transversely sleeved with a first carrying arm and a second carrying arm respectively; a sliding mechanism is connected and installed between the first carrying arm and the second carrying arm; and a line shifting stamping column is installed at the bottom of a bottom plate fixedly connected with the bottom of the sliding mechanism and makes stamping contact with an ear loop line butt joint base. According to the mask ear loop line stretching swing arm provided by the invention, a multi-dimensional automatic stretching structure is adopted, and the length of an ear belt line can be adjusted according to any size of the mask, so that the technical problemsare solved to achieved the effects that the sizes of masks are in one-to-one correspondence, and raw materials are saved; and meanwhile, a full-automatic production structure is adopted, so that theadding of some manual mask ear loop line stretching processing procedures or other imprecise mask ear loop line stretching processing procedures is avoided, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mask processing auxiliary equipment, in particular to a stretching swing arm for mask ear loops. Background technique [0002] Medical surgical masks are suitable for the basic protection of medical personnel or related personnel, as well as the protection against the spread of blood, body fluids and splashes during invasive operations. The protection level is medium and it has certain respiratory protection performance. It is mainly worn in a clean environment with a cleanliness of less than 100,000, working in an operating room, nursing patients with low immune function, and performing body cavity puncture and other operations. Medical surgical masks can block most bacteria and some viruses, prevent medical staff from being infected, and at the same time prevent the microorganisms carried in the exhalation of medical staff from being discharged directly, posing a threat to patients undergoing surgery. ...

AI Technical Summary

Problems solved by technology

Disposable medical surgical masks should also be issued to suspicious respiratory patients to prevent infection threats to other hospital personnel and reduce the risk of cross-infection, but the effect of preventing infection is not as good as medical protective masks
