AI Technical Summary

Technical Problem

Existing balance roller adjustment methods suffer from asymmetrical tension compensation and fluctuations in total tension caused by the adjustment process, which can lead to defects such as material shifting, wrinkling, tensile deformation, or even breakage during operation.

Method used

A left and right adjustment device with gears and racks in opposite directions is set at both ends of the balance roller. The central shaft is driven to rotate by a servo motor, so that the two ends of the roller produce equal and opposite lifting and lowering, synchronously increasing the tension on one side while decreasing the tension on the other side by the same amount. Real-time adjustment is achieved by using a tension sensor and controller.

Benefits of technology

It achieves stable and rapid adjustment of the tension on both sides of the material, avoids fluctuations in total tension and secondary disturbances, and improves the stability of material operation and the quality of finished products.

Abstract

This invention discloses an automatic adjustment mechanism for a balance roller, relating to the field of material processing and conveying equipment technology. The mechanism includes a balance roller and left and right adjustment devices respectively located at both ends of the balance roller. The balance roller consists of a roller drum and a central shaft fixed to both ends of the roller drum. Each of the left and right adjustment devices includes a base, an outer fixed base, an inner rotating base, a rack and pinion fixed base, a transmission rack, and a transmission gear. The transmission gears are fixedly connected to the ends of the central shafts at both ends of the roller drum. The engagement direction of the left transmission gear and the left transmission rack is opposite to that of the right transmission gear and the right transmission rack. This causes the roller drum to experience equal and opposite vertical lifting and lowering displacements when the servo motor drives the central shaft to rotate. This compensates for the lateral tension difference of the material without changing the total tension of the material, solving the problem of total tension fluctuations caused by existing unilateral adjustment methods.
