移动, 待布料器高度调整到位后, 再控制自动紧固件 60 使其处于夹持状态, 安装架 20和摊铺机后立板 70在自动紧固件 60的夹持作用下, 摩擦力较大, 使得布料器保持 在调整后的高度, 而且整个调整过程方便快捷、 节省了大量的人力, 从而克服了现有 技术中布料器通过大量紧固螺栓和摊铺机后立板连接, 导致调整布料器高度的过程费 时、 费力的问题, 进而达到了提高摊铺效率的效果。 另外, 可以理解, 也可以将纵向 滑动槽 22设置在摊铺机后立板 70上, 并将安装孔 72设置在安装架 20 上。 优选地, 由图 2中可以看出, 布料器驱动装置 11上安装的安装架和螺旋叶片支撑 装置 17上安装的安装架为一体式结构。这样较容易安装且可以有效减少安装架驱动装 置 90的数量。 优选地, 安装架驱动装置 90为液压油缸, 液压油缸的一端与摊铺机后 立板 70铰接, 另一端与安装架 20铰接, 通过控制液压油缸 90的活塞杆的伸缩, 实现 对布料器整体的高度调整。优选地, 如图 2中所示出的, 在布料器驱动装置 11的两侧 各设置有一个液压油缸, 且两个液压油缸对称, 以使安装架 20受力均匀, 移动平稳。 需要说明的是, 在本实施例中, 布料器驱动装置 11上安装的安装架和螺旋叶片支 撑装置 17上安装的安装架以一体式结构为例, 当然, 在实际应用中, 布料器驱动装置 11上安装的安装架和螺旋叶片支撑装置 17上安装的安装架也可以是分体式结构, 对 于分体式结构的安装架来说, 各安装架均需有驱动装置驱动, 且需保证各安装架的驱 动装置同步运行。 结合参考图 2、 图 3和图 4, 示出了自动紧固件 60的优选实施方式。 该自动紧固 件 60为蓄能液缸,包括蓄能液缸缸体 61和由蓄能液缸缸体 61—端穿出的第二活塞杆 63。蓄能液缸缸体 61具有连通油源的无杆腔油口 69。第二活塞杆 63穿设在安装孔 72 和滑动槽 22中, 且第二活塞杆 63的外端安装有第二锁紧件 67。 蓄能液缸缸体 61的 无杆腔内安装有弹性复位件 65。 例如, 第二活塞杆 63 的外端具有外螺纹段, 第二锁 紧件 67为锁紧螺母; 弹性复位件 65为弹簧, 套设在第二活塞杆 63上。 优选地, 蓄能 液缸缸体 61安装至摊铺机后立板 70上, 这样能保证蓄能液缸缸体 61与安装孔 72的 配合稳定。 该自动紧固件 60的松开状态是这样实施的: 当需要调整布料器高度时,控制蓄能 液缸缸体 61的无杆腔油口 69进油,在油压作用下推动第二活塞杆 63的活塞朝压缩弹 簧 65的方向运动, 此时锁紧螺母 67松开安装架 20和摊铺机后立板 70, 即自动紧固 件 60处于松开状态。此时, 可以控制液压油缸 90的活塞杆伸缩, 调整安装架 20至合 适的高度, 同时锁紧螺母 67随着液压油缸 90的活塞杆伸缩相对滑动槽 22移动。
该自动紧固件 60的夹持状态是这样实施的: 当安装架 20带动布料器调整至合适 高度后, 蓄能液缸卸载, 即蓄能液缸缸体 61 的无杆腔油口 69排油, 此时在弹簧 65 的弹性回复力作用下,第二活塞杆 63的活塞回位,将安装架 20和摊铺机立板 70夹持 在蓄能液缸缸体 61和锁紧螺母 67之间, 即自动紧固件 60处于夹持状态。此时, 布料 器保持在调整后的高度。 优选地, 在一种未示出的方式中, 自动紧固件 60还可以为液压油缸。该液压油缸 包括液压油缸缸体和由液压油缸缸体一端穿出的第一活塞杆。 液压油缸缸体安装至摊 铺机后立板 70上, 具有有杆腔油口和无杆腔油口。 第一活塞杆穿设在安装孔 72和滑 动槽 22中, 且第一活塞杆的外端安装有第一锁紧件,第一锁紧件例如为与第一活塞杆 外端螺纹配合的锁紧螺母。 通过分别控制液压油缸缸体的有杆腔油口或者无杆腔油口 的进出油, 控制第一活塞杆的伸缩, 改变锁紧螺母与安装架 20的关系, 很容易地使自 动紧固件 60处于夹持状态或松开状态, 以方便地调整布料器的高度。 优选地, 在摊铺机后立板 70上设置有限位台阶 75, 以对安装架 20的下端限位, 防止自动紧固件 60失效, 造成布料器从摊铺机后立板 70上脱落并引发危险。 需要说明的是,本发明中的安装架驱动装置 90还可以采用双向棘轮扳手或行程调 节机构代替。 另外, 上述实施例中, 以纵向滑动槽 22设置在安装架 20上, 安装孔 72 设置在摊铺机后立板 70上为例, 容易理解,还可以将纵向滑动槽设置在摊铺机后立板 70上, 安装孔设置在安装架 20上, 同样不影响本发明的实施。 通过上述实施例可知, 采用本发明的技术方案, 布料器是用液压 (蓄能液压缸和 液压油缸) 升降调整和紧固, 各液压缸的进油排油只需要通过操作控制面板的开关就 可以完成调整布料器高度的工作, 达到了布料高度调整的自动化控制, 不用再反复拧 紧固螺栓和调节螺栓了, 不仅劳动强度降到最低, 而且调整时间也最少。 根据本发明的另一个方面, 还提供了一种摊铺机, 包括上述的摊铺机的布料器的 安装结构。 以上所述仅为本发明的优选实施例而已, 并不用于限制本发明, 对于本领域的技 术人员来说, 本发明可以有各种更改和变化。 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。
