Description

Hot air cotton slitting device

Technical Field

The utility model relates to a technical field is cut to hot-blast cotton, concretely relates to device is cut to hot-blast cotton.

Background

The slitting machine is mainly used for trimming or slitting the non-woven fabric equal-width coiled materials, slitting the wound roll base material non-woven fabric with the inner diameter of a paper tube of 75 mm, the outer diameter of the non-woven fabric of 600 mm and the length within 2000 mm into a plurality of rolls with actual required sizes, and slitting the narrowest roll base material non-woven fabric into edge wrapping strips of 18 mm. The general non-woven fabric has high strength, low elasticity and low bulkiness, and the non-woven fabric is usually subjected to soft cutting, is suspended in the air without a support, and is cut above the non-woven fabric by a cutter.

The hot blast cotton is a new type of heat insulating material, and is a new generation product of spray-bonded cotton and silk-like cotton. The hot air cotton is different from the glue-sprayed cotton. The fixing method is not to adopt latex, but to mix a certain amount of low-melting-point fiber or bi-component fiber in the raw material, and the fibers are sintered after being heated in the production process. Therefore, the hot-air cotton has high production speed, high yield and low cost. The hot air cotton non-woven fabric is a filling material of an N95 mask, and belongs to one of synthetic fiber filter cotton. Has the characteristics of high filling power, good elasticity, soft hand feeling, strong heat retention, good air permeability and water permeability and the like. The ES hot-air cotton is light and fluffy non-woven fabric and is very soft. If soft cutting is used when the hot air cotton is cut, because the hot air cotton is small in strength, large in elasticity and high in filling power, a large amount of filamentous or flocculent fibers can appear in the cut edge of the non-woven fabric after cutting, so that the cut edge is not clean, and the subsequent use is seriously influenced. Hard cutting is the placement of a support under the nonwoven in the form of a cutter/nonwoven/support from top to bottom, and if soft cutting is equivalent to slitting suspended in the air, hard cutting is equivalent to cutting the nonwoven on a chopping board. The cutting speed and the winding speed of the existing splitting machine are the same, and one speed is always kept. However, in the actual winding process, the winding speed is also increased because the non-woven fabric is wound more and more. If the rolling speed is constant all the time, the hot-air cotton can be stretched continuously until the hot-air cotton is broken due to the larger elasticity; even if the hot-blast cotton is not broken during rolling, after the final rolling, an oval coiled material instead of a perfect circle can be formed, the oval coiled material is caused by the hot-blast cotton with uneven rolling tension and continuous stretching, the strength of the hot-blast cotton is reduced after the hot-blast cotton is cut, the width of the hot-blast cotton is narrowed, the obtained oval coiled material can seriously influence the production of a subsequent mask, and the production efficiency of the mask is reduced. Therefore, a hot air cotton slitting device is needed at present, so that slits of slit hot air cotton are tidy and have no burrs, an obtained slit roll is in a perfect circle shape, tension is tight, and the strength of the slit hot air cotton is not damaged.
