AI Technical Summary

Technical Problem

The fuser film in existing printers is prone to misalignment on the pressure bar, leading to problems such as friction noise, deformation, wrinkling, wear, and paper jams.

Method used

It adopts a fixing roller structure, with a contact layer on the outer sleeve that is designed to be roughened and made of fluororubber material. The mounting plate is changed to bearing mounting holes, and the fixing roller is installed through bearing components to ensure smooth rotation.

Benefits of technology

It effectively prevents the fuser film from shifting, reduces the damage rate, improves the user experience, and prevents problems such as fuser film wrinkles and paper jams.

Abstract

本实用新型公开了一种防定影膜工作中跑偏的定影辊结构，包括安装板和定影辊，所述安装板两个为一组，且互为镜像设计，每个安装板上均开设有轴承安装孔位；所述定影辊外套置有定影膜，而安装板则通过轴承件配装在带有定影膜的定影辊的两侧；所述定影辊于安装板上是为活动装配。本实用新型通过对传统压条及配装压条的安装板作出改进以避免以往套装薄膜型定影膜所出现的跑偏、易褶皱、破裂和卡纸等问题，具体是将其替换为带摩擦力好的接触层的定影辊，其能与套置在外的定影膜在工作时产生更显著的摩擦力，从而避免定影膜跑偏，且所述安装板亦作出了改进，改为能配套轴承件进行安装的轴承安装孔位，能定影辊在工作时转动更顺畅，提高使用体验的同时降低定影膜的损坏率。
