After adopting above-mentioned technical scheme, when carrying out gauze mask production, the bridge of the nose blowing of gauze mask can be carried to the rotor direction through the rotation of preceding carry out with back carry out under the elastic compression effect of pinch roller, the bridge of the nose is guided by the guide slot on carry out the surface of carry out, with the accuracy of guaranteeing bridge of the nose mounted position, after the bridge of the nose reachs the below of rotor and moves ahead certain distance (the front end of bridge of the nose has got into the double-layered in situ of gauze mask cover body this moment), the carry is stopped to the carry by the carry, simultaneously the rotation of break knife block can utilize and cut off the cutting tool block and carry out the fixed length to the bridge of the nose and cut off, the bridge of the nose that is cut off is walked along with the gauze mask body together, finally be scalded and fix in the gauze mask cover body, decide the action in order.

In order to guarantee the service life of cutting off, as preferred, the blade holder is equipped with the stereoplasm inserted block in the position that corresponds the cutting off cutter piece, and the blade holder both ends are fixed in on the mechanism wallboard.

In order to ensure the synchronism of the front traction roller and the rear traction roller for conveying the nose bridge, the belt wheels are connected with the inner shaft ends of the front traction roller and the rear traction roller as the optimization, and the servo motor drives the front traction roller and the rear traction roller simultaneously through the synchronous belt.

Preferably, the guide slots are arranged on the left side and the right side of the first outer circle surface of the traction roller, and the cutting knife blocks are correspondingly arranged in two. Carry when above-mentioned design can accomplish two bridge of the nose and decide to accomplish the simultaneous production of gauze mask machine to two gauze masks, improve gauze mask machine production efficiency.

In order to facilitate the installation and the disassembly of the cutting knife block and simplify the structure, the cutting knife block is preferably fixedly inserted on the surface of the knife roller in a pin mode.

In order to enable the nose bridge discharging of the mask to smoothly enter the guide groove of the traction roller and be guided by the guide groove, the nose bridge conveying guide plate is fixedly arranged on the mechanism wall plate on the feeding side of the front traction roller as the optimal selection, and the guide plate is provided with a guide hole.
