Abstract
Description
An acrylic heating structure Technical Field
[0001] This utility model relates to the field of acrylic sheet processing technology, and in particular to a heating structure for acrylic. Background Technology
[0002] Acrylic (polymethyl methacrylate, PMMA) sheets are widely used in advertising signage, decorative materials, and industrial products due to their excellent transparency, weather resistance, and processing performance.
[0003] During processing, localized heating is often required to bend and shape acrylic sheets. Traditional acrylic heating methods typically employ hot air guns, infrared radiation, or direct contact heating with heating wires to soften the target area before bending. However, these methods have several significant drawbacks in practical applications: existing heating methods (such as hot air guns or large-area heating elements) easily cause heat to diffuse into non-target areas, resulting in an unintended heating zone on the acrylic sheet. An excessively large heat-affected zone reduces the local rigidity of the material, leading to uneven stress distribution during bending and causing unintended deformations (such as warping and wrinkling), especially noticeable when processing thin sheets or complex shapes. Traditional techniques usually rely on natural cooling or simple air cooling, which cannot quickly reduce the temperature of the sheet outside the heated area. During bending, residual heat may continue to transfer to adjacent areas, blurring the boundaries of the softened area, affecting bending accuracy, and even requiring repeated heating and adjustments, increasing energy consumption and time costs. Summary of the Invention

[0029] An acrylic heating structure is disclosed for processing acrylic. The acrylic is placed at a conveying unit 2 and moved to a heating position.
