Description

一种大图型花式反光图案上胶装置和上胶方法 技术领域
本发明涉及反光材料生产技术领域，更具体的说涉及一种大图型花式反光图案上胶装置和上胶方法。
背景技术
现有技术中的反光材料制作工艺中使用的凹版上胶辊是通过腐蚀的方法制作上胶凹坑，因为同一辊面的花型图案有大有小，在腐蚀制辊时，面积大的图案腐蚀的深度深，面积小的图案腐蚀的深度浅。腐蚀深的地方上胶量大，浅的地方上胶量小，反映在产品出现胶层厚度不均匀，从而产生产品质量问题，为保证产品质量，要求在制作时以小图案的深度为基准，这样大图案的深度过深，耗胶量大，产生浪费，同时由于上胶量大，容易产生图案溢胶的问题。
原凹版上胶辊上胶凹坑的大小，是由图案大小决定——图案大的上胶凹坑面积也大。由于凹坑面积大，胶辊在上胶凹坑中的变形量大，把上胶凹坑中的胶水挤出凹坑后，产生图案溢胶的问题。图案越大，产品的溢胶问题越严重。所以原凹版上胶对图案的大小有限制，不能生产大花纹的图案。
原凹版上胶辊图案中有横向的线段，由于刮胶刀刀口和横向线段重叠，在压力的作用下，刮胶刀刀口变形，伸入横向线段的上胶凹坑中，把上胶凹坑中的胶水刮走，使这处产生缺胶，反映到产品时，这线段出现断胶。
为此，申请人设计了在先专利201610502217.1，通过N个小圆点构成一个大图案进行上胶的结构，解决了花式反光面料生产过程中出现的上胶层厚度不均匀、图案溢胶及图案断胶等问题。但却改变了图案的设计风格，而且最后形成的大花型图案不连续，有断点，导致客户并不接受。而且原凹版印刷由各个独立的结构单元构成，设计过程无法避免结构单元本身结构对设计带来的难题。
为了综合解决现有技术中的上述问题，本发明对上胶的生产工艺做了改变，采用正六边形/三角形/菱形/正方形微凹槽替代原有的圆点，从而很好地解决花式反光面料生产过程中出现的上胶层厚度不均匀、图案溢胶及图案断胶等问题；同时也解决了专利201610502217.1生产方式对设计风格改变的问题，可以做大花型且最后转移出的大花型图案连续，无断点并保留了原有的设计风格。
发明内容
本发明的目的是为了解决原凹版上胶辊在制作过程中的深度不均匀的问题；解决生产 过程中溢胶问题；解决生产中产生的断胶问题；解决设计风格改变的问题；以及解决图案设计问题；从而提供一种用相同的很小的图案组成设计的大图案、使胶辊在上胶凹坑中的变形可以忽略不计，使刮胶刀刀口在上胶凹坑中的变形很小，不会把上胶凹坑中的胶水带走，通过在设计图案内部填充微结构从而保证设计风格不变，设计图案能完整的呈现的大图型花式反光图案上胶装置和上胶方法。
本发明实现其第一个发明目的所采用的技术方案是：一种大图型花式反光图案上胶装置，包括上压辊、凹版上胶辊、刮胶刀及用于储存并提供胶水的供胶机构，所述的刮胶刀位于凹版上胶辊一侧，刮胶刀口与凹版上胶辊表面接触，所述的凹版上胶辊表面设有花型图案，所述的凹版上胶辊置于供胶机构内并与供胶机构内的胶水接触；所述的花型图案被分割成若干微型多边形结构凹槽或者由若干微型多边形结构凹槽组合而成，所述的微型多边形结构凹槽之间由微型薄壁阻隔，所述的微型薄壁相互之间彼此连接，所述的花型图案通过微型多边形结构凹槽内部胶水的流平作用填补微型薄壁壁厚形成的间隙以实现花型图案满图式涂胶转移。
该大图型花式反光图案上胶装置，通过对申请人现有的大图型花式反光图案进行涂胶存在转移后的花式图案给人视觉上是N个小点点构成的图案的问题，将现有的不连接的单个的凹槽为上胶凹槽组成花型图案的设计方式，改为将上胶的花型图案进行分割设计或者组合设计，花型图案可以是通过分割的方法设计，即将花型图案通过分割法设计为被分割成若干微型多边形结构凹槽的形式，也可以是通过组合设计，即花型图案设计成由若干微型多边形结构凹槽组合而成的形式，而微型多边形结构凹槽相互之间通过微型薄壁相互阻隔，且微型薄壁相互之间彼此连接，在移胶过程中，花型图案通过微型多边形结构凹槽内部胶水的流平作用填补微型薄壁壁厚形成的间隙以实现花型图案满图式涂胶转移。也就是说，本发明将凹版上胶辊上的花型图案通过分割设计或组合设计，使花型图案由同一种微型多边形结构凹槽构成的连续凹槽结构或者使花型图案由两种或两种以上多种微型多边形结构凹槽共同构成的连续凹槽结构，微型薄壁的壁厚减到一定值时，当进行涂胶转移时，由于微型薄壁的阻隔，微型多边形结构凹槽相互之间内部互不连通，上胶后，每个微型多边形结构凹槽内部都盛满胶水，在微型薄壁的壁厚处无胶水形成壁厚间隙，在上胶转移过程中，通过胶水的流平作用，将微型薄壁的壁厚宽度形成的间隙流平填平，反映在植珠膜上就是整体花型图案形成一个整体大图案，从而实现了花型图案满图式涂胶转移，转移后的花型图案能够按照最先的设计要求完整呈现，不再是给人视觉上是N个小点点构成的图案。该大图型花式反光图案上胶装置，新型凹版上胶辊是用一种或多种被分割形成微型多边形结构凹槽的花型图案或者是通过一种 或多种微型多边形结构凹槽图案组合而成的花型图案，从而将大图案分割成若干小图案，或用小图案连接组成大图案，每个微型多边形结构凹槽凹坑的深度能够根据产品对胶层厚度的要求进行设计，不存在有的凹槽深浅不一的问题；由于微型多边形结构凹槽凹坑面积很小，上压辊在微型多边形结构凹槽中的变形量可以忽略不计，解决了生产过程中的溢胶问题，也解决了不能生产大花纹图案的问题；同时很好的避免胶水因粘度过低产生的流延现象，胶水粘度使用范围更广；由于微型多边形结构凹槽的阻隔微型薄壁的壁厚足够小，刮胶刀刀口在微型多边形结构凹槽中的变形很小，不会把微型多边形结构凹槽中的胶水带走，避免了产生断胶现象的发生；微型多边形结构凹槽能无缝地被分割或者组合成各种大的设计图案，当微型薄壁的壁厚减少到一定值时，通过胶水的流动性，能填补微型薄壁的壁厚在微型多边形结构凹槽胶水转移过程中因壁厚而产生的断开间隙，即解决了胶水在微型多边形结构凹槽之间断开不连接的问题，使胶水能够在转移过程通过流平填充满整个花型图案，使得花型图案能呈满图形式完整的转移到植珠膜上，得到设计的大图型花式图案，解决了现有的凹版上胶辊上胶凹槽在移胶过程中对设计风格改变的问题。
作为优选，所述的微型多边形结构凹槽由三角形、正方形、六边形或八边形凹槽中的一种或多种组合而成。微型多边形结构凹槽可以设计成三角形凹槽、正方形凹槽、六边形凹槽或八边形凹槽，其形状的变化是根据花型图案的设计要求而变化的，而且同一图案中可以是一种微型多边形结构凹槽也可以是两种及以上微型多边形结构凹槽的组合设计，以满足不同大图型花式的设计要求。
作为优选，所述的微型多边形结构凹槽深度相同。微型多边形结构凹槽是将大图型的花型图案进行分割或组合，通过微型薄壁均化分割而成的微小凹槽，或者将微小凹槽进行组合，对微型多边形结构凹槽进行同深度设计，既方便腐蚀制作，又能够通过转移后胶水的流平作用，使得整个图案呈满图上胶，且上胶均匀一致。
作为优选，所述的微型薄壁的壁厚小于等于0.5mm。微型薄壁的壁厚优选小于等于0.5mm，是为了解决现有的凹槽相互独立，制作出的花式图案给人在视觉上是N个小点点构成图案的问题，通过这种微型薄壁的设计能够有效保留原设计风格，并且在移胶过程中可以通过胶水的流平作用解决因壁厚间隙构成的不连续问题实现满图上胶，得到原设计图案。当微型薄壁的壁厚减少到一定值时，例如小于等于0.5mm时，通过胶水的流动性，能填补微型薄壁的壁厚在上胶过程中产生的空隙，使胶水填充满花型图案，图案能完整的呈现。
作为优选，所述的微型薄壁的高度同凹版上胶辊的辊面齐平或低于凹版上胶辊辊面。这样的设计使得上压辊在凹版上胶辊上由微型薄壁分割或组合形成的微型多边形结构凹槽内 部的变形量接近零变形，上压辊在微型多边形结构凹槽中的变形可以忽略不计，有效解决了生产过程中的溢胶问题，也解决了现有技术不能生产大花纹图案或者生产出的大花纹图案呈间断的不连接的点点视觉结构的问题。同时，可以使得上胶过程中微型多边形结构凹槽内部胶水在刮胶刀刮胶过程中为零带走量。原凹版上胶辊图案中由于凹槽面积较大有横向的线段，在刮胶过程中刮胶刀刀口和横向线段重叠，在压力的作用下，刮胶刀刀口变形，伸入横向线段的上胶凹坑中，把上胶凹坑中的胶水刮走，使这处产生缺胶，反映到产品时，这线段出现断胶。而本发明中由于用微型薄壁分割或组合微型多边形结构凹槽，将大图案分割成小图案或者将小图案组成大的花型图案，因此，由于微型薄壁的格栅壁厚存在，刮胶刀刀口在微型多边形结构凹槽这种微型上胶凹坑中的变形很小，可以忽略不计，不会把上胶凹坑中的胶水带走，因而不会产生断胶现象。
作为优选，大图型是由若干微型多边形结构凹槽组合成的任意大小图案构成，或者大图型是由被分解成若干微型多边形结构凹槽的任意大小图案构成。大图型可以是由微型多边形结构凹槽组合成任意大小的图案构成，也可以是将任意大小图案分解成一定数量微型多边形结构凹槽而成，不论采用哪种方式，花型图案都可以根据需要任意设计成一种形状或者多种形状，然后再通过花型图案组成需要设计的大图型，实现在移胶过程中的满图式涂胶转移。
本发明实现其第二个发明目的所采用的技术方案是：一种大图型花式反光图案上胶的方法，包括以下步骤：
(1)植珠膜由凹版上胶辊和上压辊组牵引传送；
(2)凹版上胶辊位于供胶机构内与胶水接触，组成花型图案的微型多边形结构凹槽内部填满胶水后，在转动过程中利用刮胶刀将凹版上胶辊辊面上多余的胶水铲刮去除并落入胶槽中，仅使由微型薄壁阻隔形成的微型多边形结构凹槽内部充满胶水，其他部位无胶水；
(3)接着凹版上胶辊转动带动填满胶水的微型多边形结构凹槽与牵引传送的植珠膜经上压辊施压接触，使微型多边形结构凹槽内部的胶水被转移到植珠膜上，实现胶水转移；
(4)已转移胶水植珠膜由于微型薄壁的壁厚薄，壁厚形成的间隙通过转移后胶水的流平作用使整个花型图案呈满图式，因此在转移过程中由微型薄壁分割形成的微型多边形结构凹槽内部的胶水则清晰完整地实现涂胶转移，转印到植珠膜上形成整体设计图案；即完成整个上胶过程。
本发明的有益效果是：(1)本发明凹版上胶辊是用相同的、相互连接的不间断地连续小图案，即微型薄壁分割形成若干微型多边形结构凹槽组成大图案即花型图案，或者将若干微型多边形结构凹槽通过微型薄壁组合成花型图案，有效解决了原凹版上胶辊在制作过程中 的深度不均匀的问题，使微型多边形结构凹槽的深度能够更好地适应产品对胶层厚度的要求；
(2)本发明凹版上胶辊是使用微型薄壁分割形成很小微型多边形结构凹槽图案的组合，或者将若干微型多边形结构凹槽通过微型薄壁组合成花型图案，上压辊在微型多边形结构凹槽凹坑中的变形可以忽略不计，在上胶过程中上压辊不会将微型多边形结构凹槽中的胶水挤出，有效解决了生产过程中的溢胶问题，也解决了不能生产大花纹图案的问题；此外，本发明还很好的避免胶水因粘度过低产生的流延现象，使胶水粘度使用范围更广；
(3)本发明凹版上胶辊是使用微型薄壁分割形成很小的微型多边形结构凹槽图案的组合，或者将若干微型多边形结构凹槽通过微型薄壁组合成花型图案，刮胶刀刀口在微型多边形结构凹槽上胶凹坑中的变形很小，可以忽略不计，刮胶刀不会把微型多边形结构凹槽中的胶水带走，因而产品不会产生断胶现象；
(4)本发明由于采用微型薄壁分割形成微型多边形结构凹槽，或者将若干微型多边形结构凹槽通过微型薄壁组合成花型图案，且微型多边形结构凹槽相互之间通过微型薄壁连接成一体，不间断，不独立，通过微型多边形结构凹槽能够无缝地组合成大图案，当微型多边形结构凹槽之间的微型薄壁的壁厚减少到一定值时，在转移过程中通过胶水的流动性，能填补微型薄壁的壁厚产生的空隙，使胶水填充满我们所需要的图案，图案能完整的呈现。有效解决了生产方式对设计风格改变的问题。
(5)本发明在设计图案微型多边形结构凹槽内部通过微型薄壁连接，有效地解决了原凹版印刷由各个独立的结构单元构成，设计过程无法避免结构单元本身结构对设计带来的难题。

具体实施方式：
下面通过具体实施例并结合附图对本发明的技术方案作进一步详细说明。
实施例1：
在图1所示的实施例中，一种大图型花式反光图案上胶装置，包括上压辊1、凹版上胶辊2、刮胶刀及用于储存并提供胶水的供胶机构，所述的刮胶刀位于凹版上胶辊2一侧，刮胶刀口与凹版上胶辊2表面接触，所述的凹版上胶辊2表面设有花型图案11，所述的凹版上胶辊2置于供胶机构内并与供胶机构内的胶水接触；所述的花型图案11被分割成若干微型多边形结构凹槽5或者由若干微型多边形结构凹槽5组合而成，所述的微型多边形结构凹槽5之间由微型薄壁12阻隔，所述的微型薄壁12相互之间彼此连接，所述的花型图案11通过微型多边形结构凹槽5内部胶水的流平作用填补微型薄壁12壁厚形成的间隙以实现花型图案满图式涂胶转移。本发明中，大图型是由若干微型多边形结构凹槽5组合成的任意大小图案构成，或者所述的大图型是由被分解成若干微型多边形结构凹槽5的任意大小图案构成。
该大图型花式反光图案上胶装置，上压辊1与凹版上胶辊2上下设置且上压辊1与凹版上胶辊2之间设置间隙，该间隙形成用于通过植珠膜3的传输通道4，植珠膜3分别与上压辊1、凹版上胶辊2辊面接触，刮胶刀位于凹版上胶辊一侧，刮胶刀口与凹版上胶辊表面接触。
刮胶刀包括用于切断植珠膜与微型多边形结构凹槽5之间胶水拉丝的第一刮胶刀6以及用于刮除微型多边形结构凹槽5上胶后溢出胶水的第二刮胶刀7，第一刮胶刀6设置于植珠膜3与微型多边形结构凹槽5移胶后的脱离处并与凹版上胶辊2转动方向逆向，第二刮胶刀7设于微型多边形结构凹槽后与供胶机构的脱离处并与凹版上胶辊2转动方向同向，第一刮胶刀6的刀口、第二刮胶刀7的刀口均与凹版上胶辊辊面接触，第一刮胶刀6与凹版上胶辊2接触面之间的锐角夹角为10℃～30℃，第二刮胶刀7与凹版上胶辊接触面之间锐角夹角为10℃～30℃。
微型多边形结构凹槽5由三角形凹槽、正方形凹槽、六边形凹槽或八边形凹槽中的一种或多种组合而成。微型薄壁12的壁厚以实现胶水的流平为设计标准；微型薄壁12的壁厚 小于等于0.5mm。本实施例中，微型薄壁12的壁厚为0.2mm。微型薄壁12高度同凹版上胶辊的辊面齐平或低于凹版上胶辊辊面。
微型多边形结构凹槽5的槽体大小规格一致，槽体深度相同，微型多边形结构凹槽5的槽体深度为0.06～0.45mm。微型多边形结构凹槽5采用三角形凹槽、正方形凹槽、六边形凹槽或八边形凹槽等各种形状，其具体形状是由微型薄壁12的形状决定的。本实施例中微型多边形结构凹槽5采用的是正六边形凹槽结构。
上压辊1在凹版上胶辊2上的微型多边形结构凹槽5内部的变形量为零变形。刮胶刀刀口在微型多边形结构凹槽5中的产生细微变形，微型多边形结构凹槽5内部胶水在刮胶刀刮胶过程中为零带走量。
供胶机构包括胶罐8、胶槽9及胶管10，胶槽9固定于凹版上胶辊2下方，胶罐8固定于胶槽9的上方，胶管10固定于胶槽底部，胶罐8与胶槽9通过胶管10连通，凹版上胶辊的辊面置于胶槽内并与胶槽内的胶水接触。
利用上述大图型花式反光图案上胶装置进行上胶的方法：
(1)待转印的植珠膜3由凹版上胶辊2和上压辊组牵引传送，经过导辊输送到上压辊1与凹版上胶辊2之间的传输通道4；
(2)凹版上胶辊2位于供胶机构内与胶水13接触，组成花型图案11的微型多边形结构凹槽5内部填满胶水13后，在转动过程中利用第二刮胶刀4将凹版上胶辊2辊面上多余的胶水13铲刮除并落入胶槽9中，仅使由微型薄壁12阻隔形成的微型多边形结构凹槽5内部充满胶水13，其他部位无胶水；
(3)接着凹版上胶辊2转动带动填满胶水的的微型多边形结构凹槽5与牵引传送的通过传输通道4的植珠膜3经上压辊施压接触，使微型多边形结构凹槽5内部的胶水13被转移到植珠膜3上实现涂胶复合；
(4)已转移胶水植珠膜由于微型薄壁12的壁厚薄，壁厚形成的间隙通过转移后胶水的流平作用使整个花型图案呈满图式，因此在转移过程中由微型薄壁阻隔的微型多边形结构凹槽5内部的胶水则清晰完整地实现涂胶转移，转印到植珠膜上形成整体设计图案；即完成整个上胶过程。在凹版上胶辊2转动过程中，第一刮胶刀6切断胶水拉丝，由微型多边形结构凹槽5相互之间通过转移后胶水13的流平作用使整个花型图案11呈满版满图式，因此在转移过程中微型多边形结构凹槽5内部的胶水则清晰完整地实现涂胶转移，转印到植珠膜3上形成整体设计图案。
其中，第一刮胶刀6与凹版上胶辊辊面之间的压力为10±2kg/m 2,第二刮胶刀7与凹版 上胶辊辊面之间的压力为15±2kg/m 2。
图8是通常规上胶辊生产得到的花式反光面料上一种大花纹图案印刷效果示意。
而常规上胶辊生产得到的花式反光面料其制造工艺如下(见图12)：
(1)植入玻璃微珠：将PE/PET或PE和纸张复合膜置于热辊中，单层玻璃微珠沉降在PE膜上，实现植珠；
(2)聚焦层：将涂料涂布在上述玻璃微珠的表面，形成与玻璃微珠同球心的聚焦层，烘干为植珠膜；
(3)镀层：通过真空电阻加热蒸镀方式，制成传统植珠膜；
(4)将传统植珠膜放卷，经过导辊至复合胶涂覆机构，复合胶涂覆机构中的胶水罐将胶加热成流体状，流入胶槽中或者利用胶槽直接加热液体胶水，涂胶辊转动将涂胶辊上的花式移胶槽中填满胶水经过刮刀装置将涂胶辊辊面多余胶水刮掉，实现只有移胶槽中有胶水，其他地方没有胶水，和传统植珠膜复合，实现花式移胶槽中胶水大部分转移到传统植珠膜上，通过刮刀装置将花式移胶槽中没有完全转移的胶水，刮到花式移胶槽中，由此实现传统植珠膜凹版辊或者网线辊的上胶及转移动态过程，形成花式复合胶植珠膜；或者经过烘箱烘干后形成花式复合胶植珠膜(使用常温液体胶辊时，由于要把液体胶水中的挥发性溶剂烘干之后，再和基材复合，所以传统植珠膜在完成凹版辊或者网线辊的上胶及转移动态过程后，需要经过烘道进行烘干)。
(5)基材层：将花式复合植珠膜在复合部与基材复合，得到花式反光面料半成品。
(6)将花式反光布半成品，经过剥离部由于复合膜PE表面具有离型效果，使得PE和玻璃微珠的结合力较差，而珠子和基材之间通过胶水结合力很大，在剥离复合膜时同时没有带胶水的玻璃微珠也被复合膜带离，而有胶水的局部玻璃微珠会保留在基材上，形成大花纹图案反光，得到花式反光面料成品。
图9是通过申请人在先申请的专利花式反光面料大花纹图案凹版上胶辊装置进行上胶转印后得到的效果图。
图10是图中相同图案通过本发明的大图型花式反光图案上胶装置进行上胶转印后得到的效果图。
通过比对可知：
(一)本发明有效解决了原凹版上胶辊在制作过程中的深度不均匀的问题；
凹版上胶辊是通过腐蚀的方法制作上胶凹坑，因为同一辊面的花型图案有大有小，在腐蚀制辊时，面积大的图案腐蚀的深度深，面积小的图案腐蚀的深度浅。腐蚀深的地方上胶量大， 浅的地方上胶量小，反映在产品出现胶层厚度不均匀，从而产生产品质量问题，为保证产品质量，要求在制作时以小图案的深度为基准，这样大图案的深度过深，耗胶量大，产生浪费，同时由于上胶量大，容易产生图案溢胶的问题。
本发明采用的新型凹版上胶辊2是通过微型薄壁阻隔(分割或者组合)形成微型多边形结构凹槽，用相同的连续的小图案(微型薄壁及微型多边形结构凹槽)组成大图案，解决在制版辊中产生的深浅不均匀问题，使凹坑的深度更好地适应产品对胶层厚度的要求。
(二)本发明有效解决了生产过程中溢胶问题：
原凹版上胶辊上胶凹坑的大小，是由图案大小决定——图案大的上胶凹坑面积也大。如图5所示，由于凹坑面积大，胶辊在上胶凹坑中的变形量大，把上胶凹坑中的胶水挤出凹坑后，产生图案溢胶的问题。图案越大，产品的溢胶问题越严重。所以原凹版上胶对图案的大小有限制，不能生产大花纹的图案。
本发明采用的新型凹版上胶辊是使用微型薄壁阻隔形成很小的微型多边形结构凹槽组合成所需要的图案，如图2所示，上压辊在微型多边形结构凹槽中的变形可以忽略不计，解决了生产过程中的溢胶问题，也解决了不能生产大花纹图案的问题。
此外，对胶水粘度使用范围更广，原凹坑面积较大，对胶水的粘度要求较高，粘度太低涂布过程容易受重力作用或者刮胶刀拖延作用，产生流延现象，影响图案结构；本发明的新结构(微型薄壁及微型多边形结构凹槽)很好的避免了胶水因粘度过低产生的流延现象，胶水粘度使用范围更广。
(三)本发明有效解决了生产中产生的断胶问题：
原凹版上胶辊图案中有横向的线段，由于刮胶刀刀口和横向线段重叠，如图6、图7所示，在压力的作用下，刮胶刀刀口变形，伸入横向线段的上胶凹坑中，把上胶凹坑中的胶水刮走，使这处产生缺胶，反映到产品时，这线段出现断胶。
本发明采用的新凹版上胶辊，由于用小图案(微型薄壁及微型多边形结构凹槽)组成大图案，刮胶刀刀口在微型多边形结构凹槽中的变形很小，如图3、图4所示，不会把微型多边形结构凹槽中的胶水带走，而不会产生断胶现象。
(四)本发明有效解决了申请人在先专利版本设计风格问题：
连续设计的微型多边形结构凹槽通过微型薄壁分割或连接，能无缝地组合成各种需要的设计图案，当微型多边形结构凹槽之间的微型薄壁的厚度减少到一定值时，通过胶水的流动性，能填补微型薄壁的壁厚产生的空隙，在移胶过程中，使胶水填充满所需要的图案，图案能完整的呈现。有效解决了申请人的在先专利201610502217.1方式生产方式对设计风格改变的问 题。
(五)有效解决了图案设计问题：
原凹版印刷由各个独立的结构单元构成，设计过程无法避免结构单元本身结构对设计带来的难题，本发明新的方法是微型多边形结构凹槽通过微型薄壁连接填充，使微型多边形结构凹槽不再独立，而是连续连接成为一体，并通过胶水的流平作用实现了移胶过程中花型图案的连续的、整体式上胶，很好的解决了上胶改变设计的这一问题。
通过以上比对，本发明凹版上胶辊上的花型图案能够通过转移后胶水的流平作用，使得整个图案呈满图的方式印刷到植珠膜上，能够清晰完整的呈现原有的设计风格和设计花样，无论是大图案还是小图案都能够适用，大图型有微型多边形组合成任意大小图案，也可以是将任意大小图案分解成一定数量微型多边形，同时，对于胶水的粘度没有严格的限制，大大提高了胶水的使用范围，本发明还有效避免了生产过程中的溢胶、断胶问题。
以上所述的实施例只是本发明的一种较佳的方案，并非对本发明作任何形式上的限制，在不超出权利要求书所记载的技术方案的前提下还有其他变体及发型，都在本发明的保护范围之内。

  4. 根据权利要求1所述的一种大图型花式反光图案上胶装置，其特征在于：所述的微型薄壁(12)的壁厚小于等于0.5mm。
  5. 根据权利要求1至4任意一项所述的一种大图型花式反光图案上胶装置，其特征在于：所述的微型薄壁(12)的高度同凹版上胶辊(2)的辊面齐平或低于凹版上胶辊(2)辊面。
  6. 根据权利要求1至4任意一项所述的一种大图型花式反光图案上胶装置，其特征在于：大图型是由若干微型多边形结构凹槽组合成的任意大小图案构成，或者大图型是由被分解成若干微型多边形结构凹槽的任意大小图案构成。
  7. 一种大图型花式反光图案上胶的方法，其特征在于包括以下步骤：
    植珠膜由凹版上胶辊(2)和上压辊组牵引传送；
    凹版上胶辊(2)位于供胶机构内与胶水接触，组成花型图案(11)的微型多边形结构凹槽(5)内部填满胶水后，在转动过程中利用刮胶刀将凹版上胶辊辊面上多余的胶水铲刮去除并落入胶槽中，仅使由微型薄壁(12)阻隔形成的微型多边形结构凹槽(5)内部充满胶水，其他部位无胶水；
    接着凹版上胶辊(2)转动带动填满胶水的微型多边形结构凹槽(5)与牵引传送的植珠膜(3)经上压辊施压接触，使微型多边形结构凹槽(5)内部的胶水被转移到植珠膜上，实现胶水转移；
    已转移胶水植珠膜由于微型薄壁(12)的壁厚薄，壁厚形成的间隙通过转移后胶水的流平作用使整个花型图案呈满图式，因此在转移过程中由微型薄壁(12)阻隔的微型多边形结构凹 槽(5)内部的胶水则清晰完整地实现涂胶转移，转印到植珠膜上形成整体设计图案；即完成整个上胶过程。
