| 为了解决当下专用食品3D打印机可打印食材种类单一的问题，课题组设计了一款可打印巧克力和面点类的通用挤出型食品3D打印机。通过SolidWorks软件设计了笛卡尔坐标系形式的机械结构，并对其滚珠丝杠螺母传动机构进行了分析计算，详细介绍了其选型过程。通过气压供料、活塞挤出的方式，实现了打印喷头的连续供料功能。针对巧克力类熔融挤出低温冷却及面点类常温挤出加热熟化的食材成型特性，设计了可实现制冷和加热切换的恒温打印平台温控系统，实现了食品3D打印成型的通用性。研究结果表明该型食品3D打印机能以连续性供料的方式打印巧克力及面点类食品，顺应了多功能发展的理念。所设计的食品3D打印机可以完成一机多用的个性化食品打印，具有一定的实用价值。 |

| In order to solve the shortcomings of the single type of printed food materials of the current special food 3D printer, a general extrusion food 3D printer that can print chocolate and pastry was designed. The mechanical structure of Cartesian coordinate system was designed by SolidWorks software. The transmission mechanism of ball screw and nut was analyzed and calculated, and the selection process was introduced in detail. By means of pneumatic feeding and piston extrusion, the continuous feeding function of print nozzle was realized. The thermostatic printing platform temperature control system with refrigeration and heating switching functions was introduced to realize the generality of food 3D printing and moulding according to the characteristics of low temperature cooling in chocolate melt extrusion and heating ripening in pastry extrusion at room temperature. The results show that this type of food 3D printer can print chocolate and pastry food in a continuous way, which conforms to the concept of multi functional development. The designed 3D food printer can accomplish multi purpose personalized food printing, which has a certain practical value. |
