Design And Research Of Double Cylinder Incense 3D Printing Equipment

A variety of incense products,currently mostly based on mold manufacturing.In view of the long-term development cycle,low efficiency,high labor demand and high scrap rate in the traditional manual process of producing incense in the domestic market,there is an urgent need for research and development incense manufacturing equipment with high degree of automation,good appearance quality,various forms,personalized customization and mass production compatibility.With the rapid development of 3D printing technology,the development of incense 3D printing equipment has important practical value for improving the production efficiency of incense,reducing the processing difficulty and reducing the production cost.It has far-reaching significance for promoting the upgrading and upgrading of traditional industries of incense manufacturing and processing in China.In this paper,the design and experimental research of incense 3D printing equipment based on slurry mixed with incense ingredients and water was carried out.(1)The technical problems of the incense printing equipment under development are analyzed.Through optimization and innovative design,the technical bottlenecks such as low production efficiency of incense,unevenness of the extruded slurry,and poor precision of product molding are solved.The design scheme of the double cylinder incense 3D printing device was formulated.(2)The hydraulic power system matched with the double cylinder incense 3D printing equipment was designed,and the working conditions were analyzed.The parameters of the hydraulic cylinder,hydraulic pump and motor were designed.Based on this,the components of the hydraulic power system are selected by components,so that the hydraulic power system can continuously and stably provide pressure during the working process,and finally achieve uniform discharge.(3)A double cylinder feeding extrusion device is designed,which solves the problem that the current incense printing device cannot realize continuous production.The slide rail is used as a base,and a limiting device is mounted on the slide rail to realize the concentric connection between the cylinder and the hydraulic cylinder piston push rod.(4)Redesigned control software according to optimized mechanical design.Through the comparison of the filling method of printing,the linear filling method with moderate intensity and stability is selected,the G code of the 3D printing model is generated by the Creatbot slicing software,and the converted G code is appropriately modified according to the actual situation.(5)Based on the criterion of line width,four factors affecting the forming effect of the incense model: water mixing ratio,nozzle diameter,printing speed and extrusion pressure were comprehensively tested.Among them,the single factor experiment analyzed the influence trend of each factor on the line width value,and determined the three superior levels of each factor;The data of the five-factor and three-level orthogonal test were analyzed.It was determined that when the incense model was printed on the 300 mm×300 mm table,the optimal level combination of the process parameters was the water-material mixing ratio of 3:1,and the nozzle diameter was 0.8 mm,printing speed 2000 mm/min,extrusion pressure 1.0 MPa;significant influence factors are water-material mix ratio,printing speed,extrusion pressure.
