实施例1
一种微型辊涂机，图1、图2所示，所述辊涂机包括有机体100、辊涂布装置、驱动机构以及传动机构。

辊涂布装置包括主胶辊21、定量辊22、第一下托胶辊23和若干个支承辊24，定量辊22、主胶辊21依次沿工件行进方向安装于上墙板101上，且两辊表面紧贴在一起，紧贴位置设于主胶辊21的轴线水平面上方；第一下托胶辊23和支承辊24安装于下墙板102上，且第一下托胶辊23位于所述主胶辊21的下方。
传动机构通过齿形带，齿形轮传动组件连接所述主胶辊21和第一下托胶辊23的辊轴；驱动机构连接于所述主胶辊21，使工件在主胶辊21和第一下托胶辊23之间被驱动通过，支承辊24起到辅助支撑作用，支承辊24的数量不做限定，根据设备实际使用情况的稳定做调节，本实施例中优选为3个，见图4。
驱动机构包括减速电机31和调速器，减速电机31固定上墙板101的板面，且其输出轴连接主胶辊21的辊轴，直接驱动主胶辊21。主胶辊21和定量辊22之间靠挤压摩擦传动。
图5所示，具体的，所述齿形带，齿形轮传动组件包括主胶辊齿轮421、中间齿轮422、中间齿形皮带轮423a、公共齿形皮带轮424a、第一下托胶辊齿形皮带轮425a、第一齿形皮带426a和第二齿形皮带427a。所述公共齿形皮带轮424a的转轴与所述连接销轴112同轴安装；所述主胶辊齿轮421与中间齿轮422相啮合，所述中间齿形皮带轮423a与中间齿轮422同轴安装，且通过第一齿形皮带426a连接驱动所述公共齿形皮带轮424a，所述公共齿形皮带轮424a通过第二齿形皮带427a连接驱动第一下托胶辊齿形皮带轮425a。
主胶辊21和第一下托胶辊23的直径比是8∶5，可以是主胶辊21直径80mm，第一下托胶辊23直径50mm；主胶辊21与第一下托胶辊23的传动比是5∶8，保证主胶辊21与第一下托胶辊23的表面线速度一致，共同带动地板等工件移动。
主胶辊升降机构包括位于机体100两侧的调整轴61、弹簧62、指旋螺母63以及支撑块64；见图2。所述调整轴61下端与下墙板102前端部固定连接，所述弹簧62套在调整轴61上，所述支撑块64套在调整轴61上并压住弹簧62上端，且其固定连接于上墙板101；指旋螺母63与调整轴61上端连接并压住所述支撑块64；所述指旋螺母63的旋转改变支撑块64与调整轴61之间的弹簧长度，从而带动上墙板101绕连接销轴112转动，使安装于上墙板101上的主胶辊21升降，进而实现主胶辊21与下托胶辊23之间间隙的调整。
本实施例的辊涂机还包括有定量辊调整及锁紧机构，图6-8所示，所述定量辊调整及锁紧机构包括偏心轴71、扇形锁紧板72以及调整旋钮73。所述扇形锁紧板72由环形的轴套部721和与轴套部721轴线垂直的扇形部722组成，所述轴套部721的外径可转动安装于上墙板101，内径与偏心轴71固定连接。所述定量辊22通过轴承安装在偏心轴71上，偏心轴71上对应定量辊22的轴段与对应轴套部721的轴段形成偏心；所述调整旋钮73固定安装在偏心轴71的端部，可带动偏心轴71旋转，从而使得定量辊22的转动轴线偏移，达到调整其与主胶辊21之间间隙的目的。
所述扇形部722具有第一圆弧形通槽82，通过将锁紧螺钉穿过第一圆弧形通槽82与上墙板101连接，调整时，扇形部722与偏心轴71同步转动，调整到位后用锁紧螺钉将扇形锁紧板72锁紧在墙板上。

所述扇形板具有第二圆弧形通槽83，通过将锁紧螺钉穿过第二圆弧形通槽83与上墙板101连接，调整到位后用锁紧螺钉将扇形板锁紧在墙板上。

本实用新型还提供了微型辊涂机的另一种实施方式，除辊涂布装置和传动组件与实施例1不同之外，其他结构均相同。图9-11所示，所述辊涂布装置还包括有安装于上墙板101上的扫平辊25和刮刀10、安装于下墙板102上的第二下托胶辊26。本实施例的微型辊涂机适用于腻子辊涂；如果要用其涂布底漆或面漆，需要将扫平辊25升起。
沿工件行进方向，所述扫平辊25设于主胶辊21的前方，且其表面与主胶辊21表面紧邻在一起，所述紧邻位置设于主胶辊21的轴线水平面下方，具体为两辊表面相距0.1-1mm；所述刮刀10安装于扫平辊25的前侧上方，其下端向扫平辊25和主胶辊21的紧靠位置倾斜，并紧贴扫平辊25的表面；所述第二下托胶辊26设于所述扫平辊25的下方。
本实施例辊涂机的链轮链条传动组件包括主胶辊齿轮421、中间齿轮422、中间齿形链轮423b、公共齿形链轮424b、第一下托胶辊齿形链轮425b、第一齿形链条426b、第二齿形链条427b、扫平辊齿轮429、第二中间齿轮428、第二下托胶辊齿形链轮431以及第三齿形链条430。
所述公共齿形链轮424b的转轴与所述连接销轴112同轴安装；所述主胶辊齿轮421与中间齿轮422相啮合，所述中间齿形链轮423b与中间齿轮422同轴安装，且通过第一齿形链条426b连接驱动所述公共齿形链轮424b，所述公共齿形链轮424b通过第二齿形链条427b连接驱动第一下托胶辊齿形链轮425b，所述第二中间齿轮428分别与扫平辊齿轮429、中间齿轮422相啮合，所述第一下托胶辊齿形链轮425b通过第三齿形链条430连接并带动第二下托胶辊齿形链轮431。
其中主胶辊21与第一下托胶辊23的直径比为8∶5；所述主胶辊21与第一下托胶辊23的传动比为5∶8；所述第一下托胶辊23与第二下托胶辊26的直径相同，传动比为1∶1。
图12、13所示，所述辊涂机还包括有分别安装在两侧的上墙板101的扫平辊调整机构，其中，上墙板101的下侧部开有矩形凹槽，凹槽的顶部通过阶梯孔与上墙板101的顶部连通，所述矩形凹槽与所述扫平辊25轴向端部的安装支架154配合，所述安装支架154的顶部与连杆152连接，所述连杆152穿过所述阶梯孔，连杆152上套有螺旋弹簧153，弹簧153的一端抵住所述安装支架154的顶部，另一端抵住所述阶梯孔的肩台部，所述连杆152的顶端与指旋螺母151连接，指旋螺母151压在上墙板101上，由此通过指旋螺母151的转动调整扫平辊25升降。
工作时，扫平辊25和主胶辊21进行向上的反向转动，扫平辊25压平木材后会沾附腻子，其向上转动时通过刮刀进行清洁，同时刮下来的腻子被主胶辊21带走，进入再涂覆利用，使涂覆木材的表面平滑整洁。
一般地，一次完整的平板样品制作通常过程包括如下步骤：1.素板打磨；2.着色；3.涂布腻子(次数不定，根据基材)；4.涂布底漆(次数不定，根据基材)；5.打磨；6.涂布面漆(一般两次)。本实用新型的微型辊涂机适于完成其中的腻子、底漆和面漆的辊涂工作，且经实际使用可知，该辊涂机的使用方便且效果好。
以上所述实施例仅仅是本实用新型的优选实施方式进行描述，并非对本实用新型的范围进行限定，在不脱离本实用新型设计精神的前提下，本领域普通技术人员对本实用新型的技术方案作出的各种变形和改进，均应落入本实用新型的权利要求书确定的保护范围内。
