Description

一种密封胶自动化生产线 技术领域
本发明涉及一种智能自动化连续生产设备，尤其涉及一种密封胶自动化生产线。
背景技术
在现有技术中，密封胶的生产分为间歇式生产和连续化生产。其中，间歇式生产操作方便，生产控制相对简单，但工序之间不连贯，每个工序得到的中间产品都需要人工运输至下一个工序，造成前后工序的物料转移损耗大；并且由于前后工序之间的衔接会引起物料转移时间较长，物料暴露在空气中容易产生结皮等现象，对季节性特别敏感。因此生产可靠性差，每批质量参差不齐，不利于产品的质量控制。
目前，连续化生产线逐步得到了普及。密封胶自动化生产线主要由制胶工序与分包装胶工序组成，包括计量系统、混合系统、冷却器、过滤器、缓冲罐以及分装堆垛设备。虽然可以在一定程度上解决间歇式生产线存在的问题，但自动化生产线的各系统、各设备之间依然存在一些亟待解决的问题。如螺杆机系统压力过高，喂液存储条件不佳导致连续化生产线的生产中断或废品率增加，还有的是色料静态混合器压力过高，导致定量缸液压系统过热而生产中断。
发明内容

实施例一
如图1所示，于本实施例中，本发明所述的一种密封胶自动化生产线，包括制胶设备和包装设备。制胶设备包括储料装置1、储液装置2、送料装置3、侧喂料装置4、一阶螺杆机组5、喂液装置一6、喂液装置二7、冷热交换器8、二阶螺杆机组9、色料喂入装置10、冷却器12和缓冲罐装置13。其中，储料装置1、送料装置3、侧喂料装置4、一阶螺杆机组5、冷热交换器8、二阶螺杆机组9、冷却器12和缓冲罐装置从上游到下游依次连接。喂液装置一6包括计量斗和计量泵，通过失重精确计量。储液装置2通过喂液装置一6分别于侧喂料装置4和一阶螺杆机组5连接，将一部分液料输送至侧喂料装置4与来自储料装置1的物料进行搅拌混合，另一部分液料则直接输送至一阶螺杆机组5，与来自侧喂料装置4的经混合的物料继续搅拌混合。此外，还设置有喂液装置二7，包括计量斗和计量泵，通过失重精确计量。储液装置2通过喂液装置二7与一阶螺杆机组5连接。喂液装置二7作为喂液装置一6的辅助，可以进行更精确的液料计量，实现喂液装置一6进行粗计量，喂液装置二7进行辅助细计量的送料模式。
图2示出了本发明的储液装置的具体结构图。图中，储液装置2包括两个储液罐201，在储液罐201的下方设置有液位压力计202。液位压力计202用于监测储液罐201的液位。此外，还设置有储料高粘度泵203，其连接外部液料。本实施例中，储料高粘度泵203连接原料液体在线预配系统205。原料液体在线预配系统205包括反应釜、高粘度泵、导热油加热装置、冷却器和电气控制系统。其中反应釜安装有称重模块测量各种混合料液的重量，冷却器通冷却水，可以实现对出料降温，满足在线常温供料。当液位压力计202监测到储液罐201需要补充液料时，原料液体在线预配系统205向储料高粘度泵203供料，储料高粘度泵203启动并向储液罐201输送液料。此外，还设置有出料高粘度泵 204，用于将储液罐201的液料泵送至喂液装置一6，并经喂液装置一6输送至侧喂料装置4和一阶螺杆机组5。
优选的，各种料液存储计量都使用氮气密封。本实施例中，以储液装置为例，如图3所示，氮气密封系统包括有制氮机2011、储气罐2012、自力式减压阀2013、卸氮阀和安全阀。其中自力式减压阀2013以各个工作罐或计量斗的压力为取压点调节，取压压力控制在千帕范围内，不会对生产在线计量产生影响。
图4示出了本发明的冷热交换器的结构示意图。冷热交换器8包括一储罐801，储罐801内设置有若干铜管。储罐801的入口端连接一阶螺杆机组5的出料口，出口端连接二阶螺杆机组9的入料口。在储罐801上设置有冷冻水入口阀802、热水入口阀803、冷冻水出口阀804、热水出口阀805和料温探头806。冷冻水入口阀802和热水入口阀803采用互锁方式控制，即冷冻水入口阀802开启/关闭时，热水入口阀则处于关闭/开启状态。冷冻水入口阀802和冷冻水出口阀804采用串联方式控制，热水入口阀803和热水出口阀805也采用串联方式控制。初始时刻，料温探头806温度较低，由一阶螺杆机组5产生的热水来供给冷热交换器8。热水由热水入口阀803进入冷热交换器8内的若干铜管，并加热冷热交换器8内的原来剩余的物料。待料温探头806到达设定温度时，一阶螺杆机组5开始供给物料至冷热交换器，并输送物料至二阶螺杆机组9做准备。通过熔压探头807来监测输送物料的情况，一旦冷热交换器8内原来剩余的物料清空后，就可以按工艺要求，改为向冷热交换器8供给冷冻水。此时，热水入口阀803关闭，由于互锁控制，冷冻水入口阀802和冷冻水出口阀804开启，冷冻水经冷冻水入口阀802进入储罐801内的若干铜管，实现自动冷热转移。通过这种自带热水加热的功能，既节约了能源，又可以彻底把储罐内 原有的残余物料熔融并全部排空，使得冷冻水输入时，冷热交换器处于冷却效果最佳的状态。
如图5所示为本发明密封胶自动化生产线的色料喂入装置示意图。色料喂入装置10包括色料储料装置和计量泵。色料储料装置包括压料机1001、色料储料罐1002和阀门1003。在压料机上安装有超声波探头(图中未示出)。色料通过计量泵定量输送到二阶螺杆机组9，通过二阶螺杆机组9的均匀搅拌混合，避免了加入色料使用静态混合的高压力。同时，在压料机1001上安装的超声波探头，可以测量压盘下降位置并显示色料的储存状态。当色料储料罐1002中的色料处于低位时，可以及时报警并实现快速更换，保障连续化生产。
如图6所示为本发明密封胶自动化生产线的喂液装置三的示意图。喂液装置三11输送的是助剂，是一种易燃易爆和易挥发的液体，容易与空气反应。因此，喂液装置三11包括气动搅拌储液罐1101、计量斗1102、气动阀1103和气动隔膜泵1104，通过预定设置计量斗1102的储存量，以失重计量的方式，由气动隔膜泵1104精确地供给固定的容积量，精确的完成助剂的加入。而气动搅拌储液罐1101能均匀搅拌生产时需要的助剂，不会因为部分物质沉淀而引起助剂成分的不均匀而影响产品。并且，由于计量斗具有预存一定量助剂的功能，可以在更换储液罐时依然保持连续化生产。
优选的，本实施例中的缓冲罐装置13包括三组氮封缓冲罐装置，外围加装氮气密封。
实施例二
在本发明的又一实施例中，其余结构与上述实施例基本相同，区别在于：在缓冲罐装置13的下游，还设置有灌装装置14、自动装箱装置15和自动码垛装置16。密封胶从缓冲罐装置13中输出至灌装装置14进行定量灌装，形成瓶 装密封胶。再经自动装箱装置15对瓶装密封胶进行打包整理，将瓶装密封胶包装在纸箱中。最后装箱后的瓶装密封胶被输送至自动码垛装置16，进行自动码垛，等待运输。
其中，自动装箱装置15包括纸箱折叠装置、装箱机械手、合格证放入装置、封箱装置等。
需要声明的是，上述具体实施方式仅仅为本发明的较佳实施例及所运用技术原理，在本发明所公开的技术范围内，任何熟悉本技术领域的技术人员所容易想到的变化或替换，都应涵盖在本发明的保护范围内。
