Description

一种熔体流动速率测试装置 技术领域
本发明涉及高分子材料性能检测技术领域，特别是涉及一种熔体流动速率测试装置。
背景技术
熔体流动速率用于判定高分子材料处于熔融状态时的流动性，作为材料后期质量监控和成型工艺条件参数选择的依据，高分子材料的熔体流动速率通常需要采用熔体流动速率仪进行测试。目前，现有的熔体流动速率仪在测试时存在如下缺点：
测试时加料、压料、清理等工序均需要人工来完成，由于熔体流动速率测试过程中，过程动作较多，测试影响因素也多，采用人工操作测试时，各环节同一人员不同时间及不同人员的操作，会存在较大差异，使测试结果波动性较大，重复性差。
发明内容
本发明的目的在于提供一种自动化程度高的熔体流动速率测试装置，以解决人工操作误差大会影响测试结果的问题。
为了实现上述目的，本发明提供了一种熔体流动速率测试装置，包括安装平台、压料棒及清机杆，所述安装平台上设有熔体流动速率仪、料筒清洁组件、轨道驱动组件、料斗组件、压料棒清洁组件、称量组件、清机布取放组件、口模更换模组及压料组件；
所述轨道驱动组件上设有夹持组件；
所述熔体流动速率仪上设有料筒及位于所述料筒下端的口模，所述压料组件用于驱动所述压料棒在加料时伸入所述料筒内，所述料筒清洁组件用于驱动所述清机杆伸入所述料筒内对所述料筒清洁，所述清机布取放组件用于在所述清机杆伸入所述料筒前将清机布置于所述 料筒的上端。

所述轨道驱动组件包括两个平行分布的X轴移动轨道，两个所述X轴移动轨道之间设置有Y轴移动轨道，所述Y轴移动轨道上设置有Z轴移动轨道，所述压料棒取放组件和所述上料组件分别与所述Z轴移动轨道连接。
进一步的，所述料斗组件包括料斗支架，所述料斗支架上设有储料斗组，所述储料斗组的下方设有上料料斗，所述上料料斗的下方设有加热装置。

上述技术方案所提供的一种熔体流动速率测试装置，与现有技术相比，其有益效果在于：通过设置轨道驱动组件驱动夹持组件移动，夹持组件从料斗组件上夹取物料后自动向熔体流动速率仪的料筒内上料，在上料过程中压料组件驱动压料棒将料筒内的物料压实；测试时物料从口模下落，测试结束后将下落的物料置于称量组件上称量；在进行下次测试加料前，口模更换模组用于更换干净的口模，清机布取放组件将清机布置于料筒上端，料筒清洁组件驱动清机杆向下移动并将清机布带入料筒内部，清机杆上下移动将料筒清理干净后移出，进行下一物料的测试；压料棒清洁组件用于清理压料棒，夹持组件将清理完的压料棒再移动至压料组件上；因此，上述熔体流动速率测试装置实现了从加料、压料到清理的自动化，通过机器代替人工，保证了测试过程中操作的标准化，避免了同一人员不同时间及不同人员操作会造成测试结果差异大的现象，使测试结果更准确。

在熔体流动速率仪2中的控制平台21上设定测试温度，准备好测试负荷放到砝码加载台24上；待料筒26温度稳定后，夹持组件5移动并夹持上料料斗63，将物料加入料筒26中，在加料过程中，压料组件13驱动压料杆边加料边压实，样品添加完成后，夹持组件5将上料料斗63复位，并夹持测试压杆27到料筒26中，此时，系统传输信号给熔体流动速率仪2启动并计时。
熔体流动速率仪2计时达到规定时间后，夹持组件5将位移传感器25放到测试工位，熔体流动速率仪2上的砝码加载台24下降加载负荷，当样品从口模流出，测试压杆27下降达到规定位置后，熔体流动速率仪控制系统自动开始测试，并自动切割样品，切割后的样品，用接料盒收集，并由夹持组件5夹持到称量组件10上进行称量，称量结果自动传输给测量数据系统，并与样品入信息一一对应。
口模挡板插拔气缸23拔出口模档板，测试压杆27向下压出口模后，夹持组件5拔出测试压杆27，放到放置架上。
