Description

大容量防堵双向收纸机 技术领域
本实用新型涉及收纸设备技术领域，尤其涉及一种大容量防堵双向收纸机。
背景技术
在造纸、印刷、包装等行业中，收纸机是一种用于覆面机、覆膜机、丝网印刷机、喷码机、上光机等各种工纸面加工设备的重要部分，用于将纸顺利收集成纸垛。随着前端印刷机、喷码机等设备速度的不断提高，对收纸机的收纸速度提出了更高的要求。现有的收纸机一般采用直线式单向收纸结构，在机架内设置直线输送机构并在末端配备单个收纸台进行收集码垛，收纸量和收纸速度都非常有限，往往会发生纸张堵塞、卷边、褶皱等现象，严重影响了纸品的生产质量。
实用新型内容
本实用新型所要解决的技术问题在于克服上述问题，而提出了一种大容量防堵双向收纸机。
本实用新型的技术方案为：本实用新型所述的一种大容量防堵双向收纸机，包括机架、设于机架上的纸张输送机构以及衔接于纸张输送机构末端的收纸台，其特征在于：所述纸张输送机构呈Y型布设，包括依次连接的进纸输送段、分流输送段和自分流输送段分流形成的两个出纸输送段，所述收纸台为两个且一一对应连接出纸输送段；所述进纸输送段上平行设有多个第一输送带组；所述机架在分流输送段上可转动设有一个旋转架，还设于用于驱动旋转架转动的的旋转驱动装置；所述旋转架上端面呈圆形且间隔设有多道平行的安装空隙，且每个安装空隙内设有一个第二输送带组；所述出纸输送段平行设有多个第三输送带组；由此通过旋转架的旋转带动，第二输送带组可择一地与其中一个出纸输送段的第三输送带组连接并保持相同的输送方向；
其中，每个第二输送带组包括主动轮、两个从动轮和输送带，所述主动轮可转动设于旋转架上且所有第二输送带组的主动轮均通过一主动轴共轴联动并连接有输送驱动电机，所述从动轮分别可转动安装在安装空隙的两端，所述输送带绕设在主动轮、两个从动轮上形成传动连接；
所述旋转架内还设有负压腔和与负压腔连通的负压装置且输送带环绕负压腔设置，所述负压腔上端面开设有多道与各个输送带相对应的负压气道，输送带上设有多个负压气孔，输送带上端面覆盖在负压气道上且负压气孔与负压气道连通。
借助上述结构，本实用新型通过进纸输送段的第一输送带组实现纸张按序输送，此时分流输送段上的第二输送带组与第一输送带组同向引导纸张进入分流输送段并被负压气流吸附 在输送带上输送；旋转驱动装置驱动旋转架正转使得第二输送带组的输送方向与其中一个出纸输送段的第三输送带组相同，引导纸张进入第三输送带组继续输送到对应的收纸台上；其后，旋转架回位接下一纸张，并反转使第二输送带组与另一个出纸输送段的第三输送带组同向，纸张沿该第三输送带进入另一收纸台；由此往复交替，实现双向收纸。
进一步地，在本实用新型所述的大容量防堵双向收纸机中，所述旋转驱动装置采用步进电机。
进一步地，在本实用新型所述的大容量防堵双向收纸机中，所述旋转架在与主动轴两端对应位置处分别开设有安装口，所述安装口上设有张紧板，所述主动轴可转动连接在两个张紧板之间且输送驱动电机固定在其中一个张紧板上；所述安装口内设有至少一个上下延伸的导向条，所述张紧板上对应设有滑扣，所述滑扣与导向条形成上下滑移扣合；所述旋转架在安装口下侧还螺纹连接有调节螺钉，所述调节螺钉上端部与张紧板底部顶推配合。可通过旋转两侧的调节螺钉使其上伸长度变化，顶推张紧板沿导向条上下滑移，从而改变主动轮在机架内的高度，以达到调节输送带张紧度的目的。
进一步地，在本实用新型所述的大容量防堵双向收纸机中，所述收纸台可上下升降地活动连接在机架末端，随着纸张不断输出，不断降低收纸台的高度以保证收纸不间断地进行。
进一步地，在本实用新型所述的大容量防堵双向收纸机中，所述第一输送带组、第二输送带组、第三输送带组的输送面等高。
本实用新型的有益效果是：
1、本实用新型结构新颖，设计合理，具有双向收纸功能，设计了Y形可双向分流的纸张输送机构，利用可旋转换向的分流输送段来衔接进纸输送段和两个出纸输送段，切换输送方向实现纸张的顺畅分流过渡，并配合双收纸台完成双向收纸，显著提高收纸效率和收纸容量，能够有效避免收纸堵塞、纸张褶皱等现象。在分流换向的同时，还通过负压腔形成的负压气流将纸张吸附在输送带上，保证其旋转换向输送时不会因为旋转作用力发生偏移歪斜，确保后续收纸整齐度。
2、第二输送带的各个输送带采用共轴联动方式，保证其输送运转的一致性；同时增设了可上下滑移的张紧板结构用于安装主动轴和输送驱动电机，配合调节螺钉的旋转顶推张紧板以调节各个主动轮的高度，从而调节输送带张紧状态，收纸更为平稳，保证收纸质量。
