一种一道超重型清扫器用聚氨酯刀片
本技术涉及皮带清扫器
,尤其涉及一种一道超重型清扫器用聚氨酯刀片。
技术介绍
一道清扫器,又称头道清扫器,一般用于清扫卸载滚筒处皮带上粘附的物料,应用时需要自动调节清扫器刮板与输送机胶带之间的接触压力,保证了刮板与运行的胶带受力在一定合适的范围之内,使清料既干净,又不损坏胶带。现有一道清扫器的刀片主要采用聚氨酯材质,利用模具一体加硫成形,刮刀面平整,直线度好,低摩擦、高耐磨、高强度,具有稳定的刮料效果;可有效清除残留皮带上之细粒、湿粘物料;预压式调压器确保刮刀与皮带的稳定接触压力。现有市场上皮带机用一道清扫器种类很多,仍然存在如下缺陷:1)现有清扫器刀片不能很好的贴实皮带,清扫效果不佳;2)现有清扫器刀片硬度不能根据需要定制;3)现有清扫器刀片用合金骨架不能很好的贴实横梁,刀片易晃动;4)现有清扫器刀片不能满足超大带宽、超大载荷等需求。虽然现有的一道清扫器虽然已经采用预压式调压器使刮刀与皮带具有较稳定的接触压力,但对于一道超重型清扫器而言,由于皮带上的物料粘黏性 ...
