进一步的，输送管1包括套筒11和直管12，直管12两端分别通过管接头与套筒11和淋浇单元相连，多个进料口设于套筒11上。通过树脂进料口向套筒11中送入一定量的树脂，通过固化剂进料口向套筒11中送入 一定量的固化剂，通过控制树脂和固化剂的通入量，实现胶黏剂淋浇量的控制，且按一定配比通入的树脂和固化剂在搅拌单元的搅拌下混合均匀。树脂可为环氧树脂、乙烯基酯树脂或不饱和聚酯树脂。
如图3和4所示，搅拌单元包括搅拌驱动机构3和搅拌叶片4，搅拌驱动机构3与搅拌叶片4连接，搅拌叶片4伸入到输送管1的套筒11中以对输送至套筒2中的胶黏剂进行搅拌。
具体的，搅拌驱动机构3为气动机构，搅拌驱动机构3通过搅拌轴与搅拌叶片4连接，搅拌轴与搅拌驱动机构3相连，搅拌叶片4设置在搅拌轴上。
如图3所示，淋浇单元包括淋浇头5和淋浇盘6，淋浇头5的下端设有多个用于将胶黏剂输送至淋浇盘6处的出料口；淋浇盘6用于将胶黏剂淋浇至缠绕中的竹缠绕复合产品上；淋浇盘6设置在淋浇头5的下端。具体的，淋浇头5上的出料口沿横向等距离分布。
在一个实施例中，如图5所示，淋浇头5由横管和竖管组合而成，其中横管水平设置，竖管垂直设于横管上方的中部，竖管与横管连通；多个出料口沿着横管的轴向分布，并位于横管的下方。
在一个实施例中，淋浇单元下方设置有回收单元，通过回收单元实现多余胶黏剂的回收利用。回收单元包括回收容器7，回收容器7与回收物料输送泵8连接，回收物料输送泵8连接有回收物料输料管9，回收物料输料管9与进料口2连接。
在一个实施例中，回收单元还包括接料台10，接料台10位于淋浇单元的下方，用于接收从竹缠绕复合产品上滴落的胶黏剂和固化剂，并将其输送至回收容器7中予以回收，接料台10为倾斜平面，接料台10较低的一端设置有出料通道，该出料通道用于将接料台收集的余料导流至回收容器7中，回收容器7设置在出料通道的下方。
在一个实施例中，回收容器7内设置有上限液位传感器和下限液位传 感器，胶黏剂输送泵和回收物料输送泵8均连接有接触器，上限液位传感器和下限液位传感器与接触器电连接。

利用上述回收单元，当回收容器7中的胶黏剂达到液位上限值时，即回收容器7接满时触发上限液位传感器，上限液位传感器控制与回收物料输送泵8连接的接触器接通，则回收物料输送泵8工作，通过回收物料输料管9将回收容器7中的胶黏剂输送至输送管1中进行淋浇；当回收容器7中的胶黏剂下降到液位下限值时触发下限液位传感器，下限液位传感器控制与回收物料输送泵8连接的接触器断开，则回收物料输送泵8停止工作，并控制与树脂和固化剂输送泵连接的接触器接通，则树脂和固化剂输送泵开始工作，树脂和固化剂通过原物料输料管输送至输送管1，搅拌均匀后进行淋浇；当回收容器7中的胶黏剂再达到液位上限值时，触发上限液位传感器，上限液位传感器控制与树脂和固化剂输送泵连接的接触器断开，则树脂和固化剂输送泵停止工作，并控制回收物料输送泵8开始工作，如此往复，实现自动控制胶黏剂从两种途径中交替输送。
进一步的，接料台10包括支架和台面，台面架设在支架上，台面与支架为分体式，台面的端部设置有手抓部，便于更换、清洗台面。当然，接料台不限于上述实施例的具体结构，可以根据实际需要进行具体选择与设计。
下面将具体解释本发明方法的具体操作过程。
首先，根据竹缠绕复合产品的制备需要，设定树脂和固化剂的通入量，向胶黏剂输送设备中通入树脂和固化剂，其中树脂的通入流量与固化剂的通入流量按照胶黏剂的配比通入；开启搅拌单元对树脂和固化剂进行充分搅拌，使其搅拌均匀，获得所需的胶黏剂；
然后，搅拌后的胶黏剂依次通过输送管1和淋浇头5，经过淋浇头5上的出料口输送至淋浇盘6上；淋浇盘6将胶黏剂均匀的淋浇到竹篾带14上，保证胶黏剂浸透竹篾带14；
接着，开启竹篾带14输入设备，将浸有胶黏剂的竹篾带14从芯模13的下方输入并缠绕在芯模13上；
最后，从竹篾带14上滴落的多余的胶黏剂由接料台接收，接收后的胶黏剂通过接料台上的出料通道导流至回收容器中，以实现余料的回收利用。
当回收容器中的胶黏剂达到液位上限值时，触发上限液位传感器，控制回收物料输送泵8工作，将回收容器中的胶黏剂输送至淋浇单元中进行喷淋，并且使树脂和固化剂输送泵停止工作；当回收容器中的胶黏剂下降到液位下限值时，触发下限液位传感器，控制回收物料输送泵停止工作，并控制树脂和固化剂输送泵开始工作，实现胶黏剂的交替输送。
通过本发明添加胶黏剂，可使得竹篾带上的竹篾被胶黏剂完全包覆，浸胶率高，有效提高生产效率，降低生产成本。
本领域的技术人员容易理解，以上所述仅为本发明的较佳实施例而已，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、等同替换和改进等，均应包含在本发明的保护范围之内。
