AI Technical Summary

Technical Problem

The existing conveyor belt correction device for tunnel furnaces causes severe wear on the conveyor belt during the correction process, resulting in a short service life. Furthermore, the low coefficient of friction and limited frictional force affect equipment stability and production efficiency.

Method used

By employing a roller chain and an adjustment mechanism, the conveyor belt is reversed and corrected through frictional contact between the correction sleeve and the conveyor belt, thus avoiding sliding wear. The adjustment mechanism also adjusts the movement distance of the roller chain according to the offset, ensuring effective transmission of frictional force.

Benefits of technology

This reduces the tension requirement of the conveyor belt, extends its service life, reduces wear on transmission components, and improves the operational stability and production efficiency of the tunnel furnace.

Abstract

The present application relates to material conveying technical field, specifically to a kind of tunnel type heating conveying equipment, and tunnel type heating conveying equipment includes furnace seat and adjusting mechanism;Furnace seat is provided with conveying belt and roller chain, and conveying belt is formed with closed conveying loop on furnace seat;Roller chain extends along the width direction of conveying belt, and is formed with closed movement loop on furnace seat;Roller chain has a plurality of first and last articulated chain rollers, and chain roller extends along the movement path of roller chain;Each chain roller is all sleeved with deviation correction sleeve, deviation correction sleeve can rotate around its axis, and and conveying belt friction contact;Adjusting mechanism is configured to adjust the distance of roller chain movement in reverse according to the offset of conveying belt.When conveying belt appears offset, through the reverse axial movement of deviation correction sleeve, and under the action of friction force, conveying belt is moved synchronously, deviation correction of conveying belt is realized, so that it can effectively avoid the wear of conveying belt caused by relative sliding, and also can avoid that conveying belt bears high stress for a long time.
