Thus, when the nose bridge strip is continuously output by the conveying roller 300, the lower pressing roller 1300 can stably press the bent nose bridge strip, so that the cut finished product of the nose bridge strip is more straight, and the aim of improving the production quality of the mask is fulfilled; during actual production, the downward pressure can be adjusted according to the specification of the nose bridge strip, and the pressure of the downward pressing roller 1300 on the nose bridge strip can be realized by rotating the adjusting screw 1100 during adjustment, so that the nose bridge strips with different specifications can be straighter and tidier before shearing.

In order to improve the shearing efficiency of the lower shearing head 1500, the lower shearing head 1500 arranged opposite to the upper shearing head 420 is arranged below the shearing table 100 corresponding to the shearing head. When the upper shearing head 420 is matched with the lower shearing head 1500, the nose bridge strip can be cut off quickly, and the condition that the nose bridge strip is cut off irregularly is avoided.

The nose bridge piece deflects and leads to the circumstances such as shearing irregularity, length are inhomogeneous easily to appear when transmitting the nose bridge piece through transfer roller 300, and this embodiment is equipped with a plurality of transmission tracks 1400 between corresponding lower pinch roll 1300 of shearing platform 100 and lower shearing head 1500, and transmission tracks 1400 arrange along nose bridge piece extending direction. Like this, can transmit to shearing frame 400 below through transmission track 1400 and carry out quick shearing after nose bridge strip is straightened through lower pinch roller 1300, avoid nose bridge strip to take place to squint in the data send process.

When transfer roller 300 rotated, utilize the frictional force between transfer roller 300 and the bridge of the nose strip to drive the bridge of the nose strip and continue to remove to shearing frame 400 one side, in order to avoid transfer roller 300 to skid and lead to bridge of the nose strip conveying efficiency to descend, the outer peripheral face is equipped with the skid resistant course with bridge of the nose strip face contact on transfer roller 300 of this embodiment. The nose bridge strip can be stably promoted to move towards the shear frame 400 under the action of the anti-slip layer.
