AI Technical Summary

Technical Problem

In the long-term operation of existing hot-press laminating machines for the preparation of antibacterial composite nonwoven fabrics, the wear of the cleaning cotton causes gaps between it and the hot-press rollers, affecting the pressing effect of the equipment. Furthermore, the operators fail to detect or adjust the position of the cleaning cotton in time, resulting in the failure of the cleaning operation.

Method used

A composite device for preparing antibacterial composite nonwoven fabric is designed. By installing cleaning cotton with elastic connection on both sides of the hot press roller, the spring force ensures that the cleaning cotton is in contact with the hot press roller, automatically compensates for wear, prevents gaps from forming, and monitors the wear of the cleaning cotton through the control panel.

Benefits of technology

It effectively prevents gaps between the cleaning cotton and the hot press roller, ensuring the cleaning effect of the equipment, keeping the surface of the hot press roller clean, avoiding the accumulation of foreign matter that affects the performance of the equipment, and improving the stability and pressing effect of the equipment.

Abstract

The utility model discloses a kind of composite device for antibacterial composite nonwoven fabric preparation, including hot-pressing compound machine, the upper side of the inside of hot-pressing compound machine is equipped with one upper press roll in both ends, the lower side of the inside of hot-pressing compound machine is equipped with one lower press roll in both ends.The utility model upper press roll and the side of lower press roll outer surface are equipped with one and it is attached to the cleaning cotton, and two cleaning cottons are indirectly elastic between spring respectively, through the spring force of spring, when two cleaning cottons are worn off a layer because the outer surface of rotating upper press roll or lower press roll, the thickness of itself is reduced, two cleaning cottons can be automatically pushed to the direction of upper press roll and lower press roll, through the above technical scheme, it can be ensured that two cleaning cottons are attached to between upper press roll and lower press roll at all times, to prevent cleaning cotton outer surface from being worn off, so that the gap between two cleaning cottons and upper press roll and lower press roll is generated, and the situation that the outer surface of rotating upper press roll and lower press roll cannot be cleaned occurs.
