所述压轮15能够相对连接轴14转动的具体实施方式如下：所述压轮15与连接轴14之间设置有轴承，使得所述压轮15能够相对连接轴14转动。所述连接轴14一端固定设置在转接件上，另一端外设置有轴承，所述连接轴14将轴承内圈固定，所述压轮15套设在轴承的另一端部外，所述压轮与轴承外圈相对于轴承内圈转动。所述压轮机构还包括用于限制压轮15脱离轴承的卡紧件16，所述卡紧件16能够挡住轴承的外侧，以限制所述压轮15转动过程中脱离轴承，卡紧件16优选为卡簧，其为具有缺口的环形结构。

进一步地，所述压轮15的外周向面设置有环形皮带17，环形皮带17形成圆形结构，环形皮带17由橡胶材质制成，压轮上的圆皮带与待输送件直接接触可有效保护PCB板表面，避免划伤。
所述固定座12为倒T形结构，参见图13，所述压轮15和转接件13分别设置在固定座12的相对两侧，即所述压轮15和转接件13不在固定座12的同一侧。或所述固定座12为L形结构，参见图14，所述压轮15和转接件13位于固定座12的同一侧。所述压轮15和转接件13设置在固定座12的同一侧，或者不在固定座12的同一侧，根据位置需求进行设置，且均可实现。
所述固定座12的底部与转接件13远离压轮15的侧面均设置有紧固件19，紧固件优选为螺栓螺母组件，所述紧固件用于固定连接弹性件，一个紧固件设置在固定座12的底部，另一个紧固件设置在转接件13远离压轮15的侧面。
本发明还提供一种输送装置，其包括输送轨道1、正反双面清洁装置，所述 压轮机构设置在输送轨道1长度方向的边沿。为保证皮带上待输送件(PCB板)的清洁效果，传输皮带需要低速传送且清洁毛刷滚轮具有较高转速，在增加了压轮机构后，相对降低了PCB的传输速度，使得清洁时间更长，清洁效果得到大大改善；且压轮机构不会卡在间隙不会出现卡板现象，在有限长度空间内平稳传送待输送件，不会对待输送件造成伤害。
本发明提供的正反双面清洁装置，通过设置压轮机构，可相对降低待输送件的传输速度，延长清洁时间，同时结合模块化的清洁机构，全面清除待输送件表面灰尘，大大改善清洁效果。本发明提供的压轮机构，待输送件不会卡在间隙不会出现卡板现象，在有限长度空间内平稳传送待输送件，不会对待输送件造成伤害。
以上所述仅为本发明的较佳实施例，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
