Description

一种单张纸转移表面处理设备 技术领域
本发明涉及纸张的表面处理工艺的设备，特别是一种单张纸转移表面处理设备。
 背景技术
转移表面处理是一种纸张表面处理的先进工艺，具体有上光、镭射转印、冷烫印等工艺类型，不同的工艺类型可以通过不同转移膜来实现，即通过光膜产生纸面的上光效果，通过镭射转印膜产生纸面的激光全息纹理效果，通过冷烫印膜产生纸面的金银色效果。转移表面处理设备可以分为单张纸转印设备和卷筒纸转印设备两种，结构上有一定区别；转移表面处理工艺有整版表面处理和局部表面处理之分，主要是通过涂布紫外线固化涂料（也称UV胶或UV光油）的版辊的版面设计来解决。
中国专利第201010120892.0号公开的一种单张承印物的激光图案压印转移、冷烫两用设备，结构包括机架和分别安装在机架上的膜料放卷装置、膜料收卷装置和压印转移装置，上述膜料放卷装置和膜料收卷装置分别设在压印转移装置的上方；上述压印转移装置包括压印机构、紫外光固化机构和剥离机构，上述剥离机构设在压印机构的前方；激光图案压印转移、冷烫两用设备还包括一个间歇式膜料控制装置；上述压印机构与剥离机构之间设有一个弧形输送机构，上述紫外光固化机构设在弧形输送机构的上方；上述膜料放卷装置采用间歇式放卷驱动机构，上述膜料收卷装置采用间歇式收卷驱动机构，上述弧形输送机构采用间歇式输送驱动机构，上述间歇式放卷驱动机构、间歇式收卷驱动机构、间歇式输送驱动机构的信号输入端分别与上述间歇式膜料控制装置的三个信号输出端电连接。这一方案的缺点：一是采用弧形输送机构，输送纸张的阻力大，影响到纸张的表面处理成型质量；二是单张纸在表面处理过程没有定位，容易偏移，也影响到纸张的表面处理成型质量；三是产生效率低，造成生产成本较高。
中国专利第200710111893.7号公开的一种单张印刷机，结构是该单张印刷机具备：用于对来自供纸部的单张纸进行印刷的印刷部；和用于将转印用薄膜按压在经该印刷部进行了印刷的单张纸上而进行该单张纸的表面加工的表面加工部，该表面加工部具备：下游侧的筒体，该下游侧的筒体具备抓钳，所述抓钳抓住来自上游侧的筒体的单张纸，所述上游侧的筒体对所述印刷后送出的单张纸进行输送；该单张印刷机具备：薄膜转印机构，该薄膜转印机构向与该下游侧的筒体相同方向输送所述转印用薄膜，同时将所述转印用薄膜压到该筒体上的单张纸上；该单张印刷机具备：涂漆部，到所述表面加工部完成表面加工为止的期间，对印刷后的单张纸涂敷紫外线固化型树脂漆；以及紫外线照射部，其用于使由该涂漆部涂敷的紫外线固化型树脂漆固化。这一方案的缺点：一是转移表面处理部分的涂布紫外线固化胶的版辊20B和转移膜5（15）机构各配合不同的压印辊21B和11E，中间还设有送纸辊11D，经过的机构比较多，不利于单张纸高质量的精准转移表面处理；二是没有设置对紫外线照射部10造成压印辊11E发热的冷却措施，转移表面处理的生产效率受到限制，产量不高；三是在压印辊11E转动过程，压力辊17、18会进入叼牙槽11K，让转移膜5（15）接触到叼牙机构12，容易使转移膜5（15）受到损坏。
 技术问题
为了克服现有技术存在单张纸的转移表面处理质量不高、产生效率无法提高、转移膜的压力辊会进入叼牙槽，容易使转移膜受到损坏等问题，本发明的目的是提供一种改进的单张纸转移表面处理设备，可以克服现有技术的缺陷。

 有益效果
本发明的有益效果是：一是将送纸单元、涂布单元、转移成型单元和出纸单元都布置在一个中心压印滚筒周围并按其前后顺序与所述中心压印滚筒进行工作配合，简化了已有单张纸转移表面处理设备的结构，而且单张纸在整个转移表面处理过程都是被叼牙机构固定在一个中心压印滚筒筒面上进行，不用再转接固定在其他机构上，大大提高了单张纸转移表面处理的质量和精准程度。二是中心压印滚筒上的叼牙槽上设有与所述中心压印滚筒的筒面齐平的压力辊支撑板，使得中心压印滚筒上的叼牙槽经过转移成型单元的压力辊时，有叼牙槽上压力辊支撑板托住压力辊，避免了压力辊进入叼牙槽接触到叼牙机构，造成压力辊上转移膜被损坏；三是中心压印滚筒上还设置有筒面冷却结构，使得中心压印滚筒在作业过程长时间受到紫外线照射装置的照射后，不会产生过热变形，有效保证了中心压印滚筒周围的送纸单元、涂布单元、转移成型单元和出纸单元的良好工作状态，从而保证了转移表面处理的高质量、质量稳定性，且有效提高了转移表面处理产量。
