AI Technical Summary

Technical Problem

During use, the existing printer seal structure has accelerated wear due to the direct contact between the powder and the sealing ring, which has a short service life and high maintenance cost.

Method used

A heating table sealing structure in the printing cylinder is designed, and a barrier is used to set up a barrier between the sealing ring and the powder to reduce direct contact between the powder and the sealing ring. Through the design of removable connection and fluorescent ring, it is easy to replace the barrier ring and sealing ring, and reduce maintenance costs.

Benefits of technology

It effectively reduces the wear of the powder on the sealing ring, extends the service life of the sealing structure, reduces maintenance costs and time, and improves sealing performance, avoids powder leakage and heat loss.

Abstract

The invention relates to the technical field of printers, and discloses a heating table sealing structure in a printing cylinder, which comprises a sealing ring, the outer side of the upper part of the sealing ring is detachably connected with a barrier ring, a mounting groove is formed in the sealing ring, the bottom surface of the mounting groove is fixedly connected with a plurality of supporting rods, and the tops of the supporting rods are detachably connected with the bottom surface of the barrier ring. A guide ring is fixedly connected to the bottom face of the mounting groove, the surface of the guide ring inclines towards the middle of the sealing ring, a clamping ring is fixedly connected to the inner wall of the blocking ring, and a clamping groove corresponding to the clamping ring in position is formed in the top of the sealing ring. According to the heating table sealing structure in the printing cylinder body, a barrier is arranged between the sealing ring and the powder through the blocking ring, direct contact between the powder and the sealing ring is effectively reduced, abrasion of the powder to the sealing ring is greatly reduced, when the blocking ring is seriously abraded, the blocking ring can be conveniently detached and replaced with a new blocking ring, and the working efficiency is improved. And the maintenance cost and time are reduced.
