【摘要】 随着我国经济的发展,对木材的需求越来越大。寻求一种非木材的人造板原料已势在必行。棉杆的木质化程度较高,且来源丰富,具有较大的开发前景。本文首先对回转型棉杆重组材铺装机进行了性能试验试验研究,通过二因素四水平正交试验,研究了不同喂料方式和铺装速度对铺装均匀性的影响,为直线型棉杆重组材板坯铺装机的设计提供了基础数据;其次,对直线型棉杆重组材板坯铺装机进行了整体方案设计和结构设计;再次,应用三维造型软件对直线型棉杆重组材板坯铺装机进行了三维设计;最后应用Soildworks对主要传动部件进行了有限元分析。主要结论如下:(1)通过试验得到:回转型棉杆重组材铺装机在喂料施胶机构线速度为1.2m/s、带式输送装置线速度为1.25m/s、铺装装置线速度为0.9m/s时,铺装效果最均匀。(2)所设计的直线型棉杆重组材板坯铺装机由喂料施胶机、分支输送机、汇总铺装机三部分组成。根据回转型铺装机的试验结果,喂料施胶机的线速度选取1.2 m/s,分支输送机的速度选取0.8m/s,汇总铺装机的速度为0.9m/s。(3)汇总铺装机的总长度为40m,由10个独立铺装单元组成。每个独立铺装单元由两条相向运动的水平输送机和三条在两侧起夹持作用的输送带组成,两边有8个施胶喂料系统。(4)完成了直线型棉杆重组材板坯铺装机独立铺装单元的二维装配图。(5)运用软件对直线型棉杆重组材铺装机进行了三维实体造型。完成三维造型图并进行了静干涉检验。(6)运用SoildWorks软件对主要传动轴进行了有限元分析。三个主要传动轴均满足传动要求。
【Abstract】 With the economic development of our nation, the demand for wood is more and more big. Seek another raw material of man made board to instead of wood is imperative. The lignification of the cotton stalk is heigh and the source of cotton stalk is rich ,so the cotton stalk has larger development prospects.This paper first did some performance tests on slab forming machine of cotton stalk scrimber, using two factors four levels orthogonal test ,did some research about influence of different feeding type and feeding speed on forming uniformity. The test provide basic data to design the rectilinear slab forming machine of cotton stalk scrimber; Secondly, useing mechanical design theory made the integral and the structure design of the straight slab forming machine of cotton stalk scrimber; Again, using 3d modeling software to establish the three-dimensional modeling of slab forming machine; Finally, using Soildworks software did the finite element analysis about the the main transmission parts. The main conclusions are as follows:(1)Through the test ,the slab forming machine has the best forming result when the feeding speed of the slab forming machine is 1.2m/s,the transportation system’s speed is 1.25m/s,the line speed of the forming department is 0.94m/s.(2)The slab forming machine of cotton stalk scrimber is consist of three parts:feeding and gluing machine、branch conveyor、summary forming machine.the speed of the feeding and gluing machine is 1.2m/s,the speed of the branch conveyor is 0.8 m/s, the speed of summary forming machine is 0.94m/s.(3) Straight forming department has two horizontal conveyor which has relative movement and three conveyor belt on the side to gripping the materials. The length of the forming machine is 40m.The whole summary forming machine is consist of 10 independent forming unit, each unit have 8 feeding and gluing machine.(4) Drew the two-dimensional map of the linear slab forming machine of cotton stalk scrimber.(5) Using CATIA software to establish the three-dimensional modeling of slab forming machine. (6) Using Soildworks software did the finite element analysis about the main transmission parts.
