Mechanism for nose bridge strip cutting-off and mask flanging

Abstract

The invention discloses a mechanism for nose bridge strip cutting-off and mask flanging. The mechanism comprises a mounting plate, a bottom plate is arranged on the mounting plate, a mask guide plateis arranged on the upper part of the bottom plate, a gap allowing a mask to pass through is formed between the bottom plate and the mask guide plate, vertical plates for driving two sides of the maskto be erected are arranged on two sides of the bottom plate, and a pressing and folding mechanism for driving the two sides of the mask to be pressed and folded immediately after being erected is disposed at the tail end of the bottom plate; a nose bridge strip conveying plate is further arranged above the mask guide plate, a nose bridge strip conveying mechanism for driving the nose bridge stripto move on the nose bridge strip conveying plate and a nose bridge strip cutting-off mechanism for cutting off the nose bridge strip are sequentially arranged on the mounting plate in the movement direction of the nose bridge strip, the tail end of the nose bridge strip conveying plate is equipped with a guide conveying mechanism for driving the nose bridge strip to move to the inside of mask flanging. According to the invention, by arranging the pressing and folding mechanism, smooth folding of two sides of the mask is guaranteed, and meanwhile the cut-off nose bridge strip can precisely enter the inner side of the folded edge through the arrangement of the guide conveying mechanism.

Description

technical field [0001] The invention relates to a production equipment of a mask machine, in particular to a mechanism for cutting off a bridge of the nose and turning over the edge of a mask. Background technique [0002] In the production process of masks, it is necessary to go through steps such as shaping, cutting the nose bridge strip, turning the mask edge, welding the edge of the mask, welding the ear strap line, and folding the ear strap. The flanging on both sides cannot be turned in place, so that the bridge of the nose cannot accurately enter the inside of the flanging, which affects the subsequent welding of the edge of the mask, thereby affecting the yield of the mask production. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a mechanism for cutting the bridge of the nose and for turning the mask, which can ensure the yield rate of the turning operation. [0004] The technical solution adopted by t...
