Description

Mask nose bridge strip destressing straightening device and mask production line

Technical Field

The utility model relates to a gauze mask bridge of the nose strip destressing coalignment and gauze mask production line.

Background

In order to fix the mask on the face conveniently, a nose bridge strip is pasted on the upper edge of the mask, and the mask is attached to the nose wing through the deformation of the nose bridge strip, so that the mask is prevented from falling. At present, a nose bridge strip of a mask is generally a metal product, and a layer of resin or cotton yarn is wrapped outside a metal strip in some cases, so that the nose bridge strip of the mask has good plasticity, is nonconductive in appearance and can prevent static electricity. However, in the production process of the mask, the nose bridge strip is not straight, such as bent and upwarped, and the nose bridge strip which is too soft and too hard is not favorable for the stable operation of the mask production line, or the nose bridge strip cannot enter the folded edge of the non-woven fabric after being chopped, or the non-woven fabric cannot be punctured, or the nose bridge strip is in a plane arc shape, or the nose bridge strip is in an arch arc shape, and the like, which makes the operation difficult to grasp, causes a lot of waste and defective products, and seriously affects the production. For example, the nose bridge strip of the mask cut by the automatic cutting device for the nose bridge strip of the mask disclosed in chinese patent publication No. CN 206966761U is in a planar arc shape or an arched arc shape. The automatic shearing device for the nose bridge strip of the mask comprises a base, a material conveying device, a clamping device and a rotating device, wherein a through groove is formed in the middle of the upper end of the base, the material conveying device is arranged at the bottom end in the groove of the through groove, supporting plates are symmetrically arranged at the top ends of two rods of a U-shaped supporting frame on the material conveying device, the clamping device is arranged at the upper end of each supporting plate, L-shaped supporting columns are symmetrically arranged in the middle of the two side faces of the base, vertical electric telescopic columns are arranged at the top ends of the L-shaped supporting columns, bent rods are arranged at the top ends of the vertical electric telescopic columns, the top ends of the bent rods are fixedly connected with the side faces of the rotating device, a rotating motor is arranged at the top end of a second rotating shaft in the rotating device, an output shaft of the rotating motor is fixedly connected with one end of the rotating shaft through a coupler, the other, the input electricity of PLC controller is connected external power source, the input of vertical electric telescopic column and rotating electrical machines is connected to the output electricity of PLC controller.

The nose bridge strip of the mask cut out in this way is warped due to the action of stress, or is in a plane arc shape, or is in an arch-forming arc shape, and the like, so that the arch of the mask is in an arc shape, and the skin of a user can be stabbed to become a defective product.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to avoiding the bridge of the nose strip at present because the effect of stress or become plane arc, or become to encircle the arc and so on, some upwarp of the gauze mask bridge of the nose strip of producing cause the gauze mask to arch and be the arc, can stab user's skin and become the substandard product, provide a gauze mask bridge of the nose strip destressing coaling device and gauze mask production line, at the in-process destressing of alignment.

The utility model discloses a realize that it uses the technical scheme that novel purpose adopted is: a stress-relieving straightening device for a nose bridge strip of a mask comprises a bracket, wherein a feeding guide wheel, a front wire passing device, at least two adjustable pressure guide wheels and a rear wire passing device are sequentially arranged on the bracket from front to back, and an upper traction roller and a lower traction roller which are mutually extruded in the vertical direction are arranged behind the rear wire passing device; the nose bridge strip of the mask is guided by the feeding guide wheel to enter the front wire passing device, then sequentially and alternately enters the rear wire passing device from the upper side and the lower side of the adjustable pressure guide wheel, and then passes through the space between the upper traction roller and the lower traction roller after coming out of the rear wire passing device and is drawn out by the upper traction roller and the lower traction roller.

The utility model discloses in, under the traction force effect of last carry over pinch rolls and carry over pinch rolls down, gauze mask bridge of the nose strip utilizes more positive adjustable pressure guide pulley to carry out the destressing after, can avoid the crooked phenomenon of warping up etc. of bridge of the nose strip, improves the stability and the speed and the quality of gauze mask production line.

Further, among the above-mentioned gauze mask nose bridge strip destressing straightener: the support is a back plate, and the feeding guide wheel, the at least two adjustable pressure guide wheels, the upper traction roller and the lower traction roller are respectively fixed on the back plate through respective shafts.
