Abstract
The utility model provides a gauze mask ear area shear structure, including cylinder, first shear blade and second shear blade are articulated and set up the one end at the cylinder, the handle end of first shear blade and second shear blade stretches into and sets up in the cylinder, the cutting edge of first shear blade is crescent moon sword and arc angle is 156 °, and the edging angle is 55. The utility model provides a pair of gauze mask ear area shearing mechanism, simple structure, convenient to use, wherein the circular arc angle is 156, and the angle of opening a knife edge is 55, can general all gauze mask ear area stable shearing of material on the market, and can guarantee even also can accomplish not block the line, not wire drawing, not fluffy, not askew line and not slide line in high-speed production process.
Description
Technical Field
The utility model relates to a gauze mask production facility, in particular to gauze mask ear area shear structure.
Background
In the existing individual product mask machines and ear belt machines, in the ear belt shearing link, the multi-purpose processing type mechanical structure shearing tool or the single-action pneumatic scissors (one side of a shear blade is in action, and the other side of the shear blade is fixed) or the cylinder welding shear blade and other assembly type processing shearing tools are adopted. At present, all shearing structures are unstable in long-term shearing, and are easy to clamp, cut and draw wires and fuzz cut. And the cutting edge is a notch under the long-term operation condition. All cutting tool edging modes are flat straight edging modes, so that a round ear belt (taking a plane mask as an example) or a large-diameter round ear belt (taking a cup-shaped mask as an example) or a large-width flat wire ear belt (taking a KN95 mask as an example) is cut to be a skew wire, the wire slides, the wire head is deviated seriously and is deviated randomly, and the wire head is not well welded when the ear belt is welded, the welding is not accurate, the welding is incomplete, and the yield in the production process is not high.
SUMMERY OF THE UTILITY MODEL
Not enough to the above-mentioned among the prior art, the utility model provides a gauze mask ear area shear structure, its simple structure, convenient operation can guarantee even also can accomplish not block the line, not the wire drawing in high-speed production process.
In order to achieve the above object, the utility model adopts the following technical scheme:
the utility model provides a gauze mask ear area shear structure, includes cylinder, first shear blade and second shear blade are articulated and set up the one end at the cylinder, the handle end of first shear blade and second shear blade stretches into the cylinder and sets up, the cutting edge of first shear blade is crescent blade and circular arc angle and is 156 °, and the angle of opening a knife is 55.
The utility model has the advantages that:
the utility model discloses simple structure, convenient to use, wherein the circular arc angle is 156, and the angle of cutting edge is 55, can general all gauze mask ear area material on the market stable cut, and can guarantee even also can accomplish not block the line, not wire drawing, not fluffy, askew line and not slide the line in high-speed production process.
