Description

PVB树脂增塑挤出一体化装置
技术领域
本实用新型涉及一种PVB树脂增塑挤出一体化装置，该装置用于将PVB树脂与增塑剂进行精确配比并混炼挤出。
背景技术
在PVB树脂加工的过程中，须将粉状PVB树脂与增塑剂以一定比例配混造粒，目前传统的加工方式是：将粉状PVB树脂与增塑剂以一定比例投入搅拌机进行搅拌，使树脂与增塑剂混合均匀，然后通过双螺杆挤出机造粒，再通过单螺杆挤出机熔融挤出加工成片材。这种加工方式存在的缺陷是：树脂与增塑剂混合搅拌后，树脂体积膨胀比重变小，使得双螺杆挤出机造粒时下料困难；同时所制得颗粒黏度很大，须保证存储温度在12℃以下，否则将造成颗粒抱团，后续加工时无法投料。另外，造好的颗粒还须再用单螺杆挤出机熔融挤出，物料二次受热，将造成物料中降解物的增加，导致产品发黄、发暗，产品性能遭受影响。
实用新型内容
本实用新型要解决的技术问题是：对粉状PVB树脂进行增塑加工，目前采用的传统加工方式存在工序多、加工效果不佳的缺陷，为克服该缺陷，提供一种PVB树脂增塑挤出一体化装置，该装置能够将粉状PVB树脂与增塑剂进行精确配比并混炼挤出，且一体化完成。
本实用新型采用的技术方案是：一种PVB树脂增塑挤出一体化装置，用于PVB树脂与增塑剂的精确配比并混炼挤出，其具有由PLC控制器控制的双螺杆挤出机及分别用于存装粉状PVB树脂与增塑剂的料仓，存装粉状PVB树脂的料斗其下端设置有由PLC控制器控制的出料计量螺杆，出料计量螺杆的出料口对准双螺杆挤出机的进料口；存装增塑剂的料斗其下端设置有由PLC控制器控制的高压注液泵，高压注液泵的出液管头端带有喷枪，喷枪连接双螺杆挤出机注液口。
本实用新型的有益效果是：该装置实现了PVB树脂加工过程中增塑、熔融混炼及挤出三工序的一体化，减少了生产流程，提高了生产效率。装置通过PLC控制器对出料计量螺杆与注液泵的精确控制，实现了树脂与增塑剂的精确配比，物料在双螺杆挤出机一次受热，熔融混炼一次完成，物料降解率显著降低，产品质量得到了有效提高。
附图说明
下面结合附图和实施例对本实用新型作进一步说明。
图1是本实用新型的结构示意图；
图中1.双螺杆挤出机  2.出料计量螺杆  3.高压注液泵  4.喷枪
具体实施方式
如图1所示，一种PVB树脂增塑挤出一体化装置，用于PVB树脂与增塑剂的精确配比并混炼挤出，其具有由PLC控制器控制的双螺杆挤出机1及分别用于存装粉状PVB树脂与增塑剂的料仓，存装粉状PVB树脂的料仓其下端设置有由PLC控制器控制的出料计量螺杆2，出料计量螺杆2的出料口对准双螺杆挤出机1的进料口；存装增塑剂的料斗其下端设置有由PLC控制器控制的高压注液泵3，高压注液泵3的出液管头端带有喷枪4，喷枪4连接双螺杆挤出机1注液口。
装置被启动后，存放于料仓内的粉状PVB树脂在出料计量螺杆的控制下稳定、连续地输入到双螺杆挤出机内，增塑剂在高压注液泵及喷枪作用下，以雾状喷注入双螺杆挤出机内。PLC控制器精确控制计量螺杆与高压注液泵的输出功率，实现树脂与增塑剂的精确配比。树脂和增塑剂在双螺杆挤出机的溶涨段混合溶胀，在混炼段反复混炼后挤出。
