AI Technical Summary

Technical Problem

During cigarette production, the high temperature generated when the alloy cutter comes into contact with the high-hardness filter tip during high-speed rotation causes the glue to melt and accumulate on the cutting edge, which is difficult to remove. This results in high burr defects in the cut high-hardness filter tip, reducing the cutting quality.

Method used

Design a blade cleaning device, including a support plate, an arm plate and a scraper. The arm plate is tightened by an elastic element so that the adhesive removal surface of the scraper clamps the blade edge, and combined with a blower mechanism, the accumulated adhesive is removed.

Benefits of technology

It effectively removes accumulated glue from the cutting edge, improves the cutting quality of high-hardness filter tips, reduces burr defects in high-hardness filter tips after cutting, and lowers production costs.

Abstract

本实用新型涉及切刀清洁技术领域，尤其涉及一种切刀清洁装置及卷烟机。切刀清洁装置包括支撑板、臂板、刮刀和弹性件，支撑板被配置为安装于卷烟机的支架。支撑板转动安装有两个相对设置的臂板。刮刀的外周设置有除胶面，每个臂板的第一端均伸出支撑板并安装有刮刀。每个臂板的第二端与支撑板之间均设置有弹性件，以通过弹性件拉紧对应的臂板，以使两个臂板的第一端始终具有相互靠近的趋势，且两个刮刀的除胶面能够夹紧卷烟机的切刀的刃口。卷烟机包括上述的切刀清洁装置，当切刀旋转时，两个刮刀的除胶面能够将切刀的刃口两侧的积胶刮除，提高了卷烟机对高硬度滤嘴的切割质量，改善了切割后的高硬度滤嘴毛口缺陷。
