New correcting method and device of metal conveyor belt

Abstract

The invention discloses new correcting method and device of a metal conveyor belt, belonging to the correction field of mechanical devices. In the invention, by adopting a correction mode of a permanent magnet or an electromagnet, the conveyor belt is limited in deviation by magnetic force or the deviated conveyor belt is pulled back to a normal track, i.e. grooves or convex edges are arranged at two ends of a driving roller of the metal conveyor belt, magnetic correcting devices with magnetism opposite to or same as that of the corresponding sides of the metal conveyor belt are arranged on two inner sides of the grooves or the convex edges, two sides of the metal conveyor belt are folded into folded edges with the depth corresponding to the depths of the grooves or the convex edges or small magnets are arranged at intervals on two sides of the metal conveyor belt so as to increase the magnetic action and strengthen the magnetic action effect. The invention is simple and feasible, effectively overcomes the defects of side deformation and cracking of the metal conveyor belt caused by the deviation in the background art and ensures normal production.

Description

technical field [0001] The invention belongs to the category of deviation correction of mechanical devices, in particular to a new deviation correction method and device for metal transmission belts. Background technique [0002] The metal conveyor belt is often supported by many transmission rollers on the machine for circular motion. If the processing accuracy of the transmission rollers and the horizontal parallelism of the installation do not meet the requirements, this will cause the conveyor belt to deviate and affect normal production. For example, metal conveyor belts are used in the production lines of coatings, sulfur, solid surfactants, wooden press plates, and paperless thermal transfer printing and dyeing machines. At present, the deviation correction of these metal conveyor belts adopts mechanical correction methods. Since the metal conveyor belt is very thin, mechanical deflection correction is likely to cause deformation or even cracking of the side of the me...

AI Technical Summary

Problems solved by technology

Because the metal conveyor belt is very thin, mechanical correction is prone to the disadvantages of deforming the side of the metal conveyor belt, or even cracking

In order to solve this problem, the invention patent 02159175.X of Beijing Institute of Fashion Technology proposed a magnetic force and friction roller rectification method, but this method has the following disadvantages: 1. Since the magnetic force mainly acts on the direction perpendicular to the magnetic force line, in the direction of the magnetic force line The tangential direction is very weak. The magnetic correction device set in this patent is realized by relying on the magnetic force in the tangential direction, so the magnetic force is very weak, and it is difficult to correct the deviated belt; 2. If the friction resistance of the rubbing roller is too small , the correcting effect is weak, if the correcting effect is too strong, it will easily cause the belt to wrinkle, especially the thin belt
