Non-woven fabric slitting equipment

Abstract

The invention relates to non-woven fabric slitting equipment. The non-woven fabric slitting equipment is suitable for slitting non-woven fabrics such as spunbonded fabrics, needle-punched fabrics and melt-blown filter fabrics made of high-molecular polymers and the like. The non-woven fabric slitting equipment comprises an unwinding frame, a slitting rack, a magnetic damping tension controller, a non-woven fabric winding roller, a first fabric guide roller, a fabric expanding roller mounting frame, a cutter mounting frame, a fabric expanding roller, a second fabric guide roller, an adjustable fabric cutter, a fabric cutter shaft, a cutter motor, a winding roller, a winding motor, a frequency converter, a fabric receiving roller, a rapid clamping device, an air cylinder, a guide rod and a collecting plate; the non-woven fabric winding roller is mounted on one side of the unwinding frame; the non-woven fabric winding roller is connected with the magnetic damping tension controller through two gears which are meshed together; the first fabric guide roller is arranged at the other end of the unwinding frame; the cutter mounting frame is arranged at the front end of the slitting rack; the fabric expanding roller mounting frame is arranged at one end of the cutter mounting frame; the air cylinder and and the fabric expanding roller are mounted on the fabric expanding roller mounting frame; and when non-woven cloth passes through the lower portion of the fabric expanding roller, the fabric expanding roller is driven to rotate.

Description

Technical field [0001] The present invention relates to a nonwoven cloth division cutting device, suitable for dividing the nonwoven fabric, such as a spunbond, a needle, a meltblown filter cloth such as a polymer polymer. Background technique [0002] At present, the nonwoven cloth is generally used in thin film slitting equipment. During the division process, due to the mechanical vibration, the phenomenon of nonwoven layers is close to the middle, resulting in a nonwoven fabric in the rear end divide and the winding end Cut wrinkles, slit, wool, and hood, etc., causing a midway stop. At the same time, there is a phenomenon that the release tension is not stable, causing unevenness inside and outside the cloth, and the improvement of the finished resistance change fluctuates, which is easy to cause reduction in manufacturing and increased waste. Artificial loading and unloading rolls, workers' labor intensity, labor efficiency needs to be improved. Inventive content [0003] I...

AI Technical Summary

Problems solved by technology

[0002] At present, non-woven fabrics are generally cut by film cutting equipment. During the cutting process, due to mechanical vibration, the non-woven fabric will move closer to the middle, causing the non-woven fabric to appear split at the back-end slitting and winding end. Wrinkled cutting, uneven cutting, rough edges, convex caps, etc., resulting in midway stoppage

At the same time, the cloth tension is not stable, resulting in uneven tightness of the cloth roll inside and outside, and the phenomenon of large fluctuations in the resistance of the finished product, which may easily lead to a decrease in the production rate and an increase in waste.

Manually loading and unloading the cloth receiving rollers, the labor intensity of the workers is high, and the labor efficiency needs to be improved
