常温挤出糖霜3D打印机设计

The design of 3D icing sugar printer based on room temperature extrusion

目的:设计一款满足安全、卫生、操作便捷、结构性能稳定等要求的糖霜制品3D打印机。方法:打印机主要包括机械结构和控制系统,机械结构方面采用龙门架结构,并对传统的打印料罐进行改良。控制系统采用“工控机+运动控制卡”的模式。结果:该打印机可快速更换料罐(30 s内),打印机成型速度快(≥5000 mm/min),速度可调;成型精度控制在1 mm以内;成型件的强度、膨胀率和表面粗糙度指标均较好。自带光源的图像识别及处理系统能够识别产品形状、个数及完整性等。结论:改良后的料罐提高了半流体食品打印的卫生性、生产效率,且便于耗材的更换,能加工出复杂糖画模型以满足造型独特的个性化糖艺制品的需求。

Objective:The paper aims to design a 3D icing sugar printer that meets the requirements of safety,hygiene,convenient operation,and stable structural performance.Methods:The 3D icing sugar printer includes the mechanical mechanism and control system.The mechanical structure adopts a gantry structure and reforms the food can.The control system adopts"Industrial PC+Motion control card"mode.Results:Fast food can replacement(<30 s);fast printing speed(≥5000 mm/min),adjustable speed;printing accuracy(<1 mm);good strength,expansion rate and surface roughness of the printed objects.The image recognition and processing system with the self-light source can identify the shape,number and integrity of the printing objects.Conclusion:The reformed food can improves the hygiene,production efficiency of semi-fluid food printing and is replaced quickly.The 3D icing sugar printer has stable structural performance and convenient operation,and can print icing sugar products that meet different design requirements.
