AI Technical Summary

Technical Problem

Traditional plate rolling machines are difficult to adapt to mirror aluminum coils with different thicknesses and curvatures, and are prone to damaging the surface of mirror aluminum during the rolling process, causing scratches and indentations.

Method used

A scratch-resistant pressure roller structure for a mirror aluminum coil machine was designed, including a fixed base, a fixed pressure roller, an adjusting slide, a limiting mounting bracket, and an adjusting pressure roller. The gap between the pressure rollers is adjusted through gear and rack transmission and a drive motor to prevent indentations.

Benefits of technology

It enables precise rolling of mirror aluminum materials of different thicknesses, preventing the pressure rollers from damaging the surface of the mirror aluminum during the rolling process, and has a good adjustment and protection effect.

Abstract

This utility model discloses an anti-scratch pressure roller structure for a mirror aluminum coiling machine, including a fixed base, a fixed pressure roller mounted on top of the fixed base, a coil thickness adjustment slide mounted on one side of the fixed pressure roller, a limit mounting frame mounted on the coil thickness adjustment slide, and a first adjustment pressure roller and a second adjustment pressure roller respectively mounted on the limit mounting frame. The front end of the coil thickness adjustment slide is connected to the fixed base through a limit plate, and the coil thickness adjustment slide is slidably connected to a groove set on the inner wall of the fixed base through a drive slider. This utility model, by providing a coil thickness adjustment slide with convenient drive control, can be used to adjust the thickness of the coil gap between the adjustment pressure roller and the fixed pressure roller on the limit mounting frame, thereby enabling coiling operations for mirror aluminum materials of different thicknesses, better adjusting the tightness between the pressure rollers, preventing the pressure rollers from scratching the surface of the mirror aluminum, and providing good adjustment and protection effects.
