Description

Technical Field

[0001] The invention belongs to the technical field of mask equipment, and in particular relates to a method for manufacturing a safety protective mask. Background Art

[0002] In industrial production, people's faces are often harmed by high-speed particles, molten metal, chemical liquid splashes and harmful light, and various protective masks must be used for protection.

[0003] A protective mask is a device used to protect the face and neck from flying metal debris, harmful gases, liquid splashes, metal and high-temperature solvent flying powder.

[0004] There are many types of protective masks, but according to their uses they can be roughly divided into four types: anti-impact masks, anti-corrosive liquid splash masks, anti-dust, smoke and various toxic gas masks, and anti-radiation masks. These masks must be equipped with observation windows.

[0005] When in use, the protective mask should be clean, transparent, and free of scratches or cracks. The connection between the mask and the hat stand should be secure. The straps of the hat stand should be easy to adjust so that it is appropriately tight, safe, and comfortable to wear on the head.

[0006] However, in the prior art, the manufacture of protective masks is usually carried out by manual assembly. At the same time, the manual assembly of protective masks has low precision and low processing efficiency, and cannot achieve mass production, which can no longer meet the existing production needs. Summary of the invention

[0007] The purpose of the present invention is to solve the above-mentioned technical problems existing in the prior art, and provide a manufacturing method of a safety protective mask. The protective mask is assisted in manufacturing by using an assembly table. First, various components required for manufacturing the protective mask are prepared, and then the various components are clamped and fixed. The back of the elastic fixed rear seat is clamped upward in the flip clamping assembly of the assembly table, and the elastic fixed front seat is fixed on the top of the lifting assembly mechanism. The transparent face cover plate is adsorbed on the bottom of the lifting assembly mechanism. The back of the elastic fixed rear seat is clamped and fixed to facilitate the installation of the elastic band. After the elastic band is installed, the flip clamping assembly drives the elastic fixed rear seat to flip, and then the lifting assembly mechanism installs the adsorbed transparent face cover plate on the elastic fixed rear seat. After the lifting assembly mechanism is reset, the elastic fixed front seat is driven to rotate, so that the elastic fixed front seat rotates from the top to the bottom, and the elastic fixed front seat is driven to descend again by the lifting mechanism, so that the transparent face cover plate is fixed between the elastic fixed front seat and the elastic fixed rear seat, and then the fastening screws are screwed in to fix it, and the manufacturing of the protective mask is completed, the manufacturing accuracy of the protective mask is improved, the manufacturing efficiency of the mask is greatly improved, and the mass production of the protective mask is realized.
