液滴腔涂布嘴的研磨加工与生产验证

Grinding process and production verification of droplet cavity coating nozzle

涂布嘴是相纸涂布生产中最重要的设备,其性能、精度直接影响着相纸的质量。三号机引进了柯达的新涂布嘴加工制作技术,液滴结构腔体与阶梯坡流面设计,打破了传统衣架腔设计思路,为涂布技术的发展做了巨大贡献。自2006年起至今,三号机装备技术团队与乐凯制安公司深入交流,细化分解了液滴腔涂布嘴加工的工艺技术,为三号机加工了三套涂布嘴。加工过程中,全程跟盯了三套涂布嘴设计方案论证与加工检验工作,从前期选材调质、机械加工、研磨、检测、组装,到后期出口间隙检测和生产性能横向统一性检测等,积累了较为丰富的工作经验,为相纸生产提供了高性能、高精度的装备技术保障。

Coating mouth is the most important equipment in the production of paper coating,its performance,precision directly affect the quality of paper.No.3 machine introduced kodak's new coating nozzle processing technology,droplet structure cavity and stepped slope flow surface design,broke the traditional hanger cavity design ideas,made a great contribution to the development of coating technology.Since 2006 until now,no.3 machine equipment company technical team and a lucky Ann in-depth communication breakdown the droplet mouth cavity coating processing technology,for the three sets of no.3 machining coated mouth,machining process,the whole and stared at the three sets of coated mouth design scheme comparison and the processing and inspection work,from the previous selection conditioning,machining,polishing,testing,assembly,In the later stage,we have accumulated rich working experience in export clearance detection and horizontal uniformity detection of production performance,providing high performance and high precision equipment technical support for the production of photographic paper.
