【摘要】：非PVC多层共挤膜输液用袋(简称非PVC软袋)是目前大输液最新式的包装形式,因该输液采用全封闭输液系统,仅利用外界大气压缩袋体即可顺利滴注和加压输液,排除了空气污染和空气栓塞的危险,是最健康的输液包装形式之一。目前市面上的非PVC软袋输液产品虽都符合国家质量标准,但部分产品在装卸及来回搬运过程中易出现漏液情况,这是产品生产企业面临的大难题。这主要是因为非PVC软袋是由非PVC多层共挤膜、聚丙烯接口及聚丙烯组合盖通过高温焊接制成,而部分产品焊接部位较脆弱,在装卸和搬运过程中断裂造成漏液。而且目前生产非PVC软袋的物料厂家众多,在使用不同的物料时没有明确的工艺参数,仅是靠生产经验来保证产品质量。非PVC软袋是由全自动制袋灌封机生产出来的。设备工位包括接口预热、周边热合、接口焊接、口盖焊接等。本课题主要是根据使用不同厂家的物料调整焊接模具并制定明确的焊接参数,从而对焊接工艺进行优化,提高产品焊接质量。本课题在接口预热工位、周边热合工位、接口焊接工位及口盖焊接工位先是明确了模具的组装及调整的要求,再是对各个工位的焊接标准进行明确,最后针对不同厂家的物料在各个工位时对不同的焊接温度进行效果试验,最终确定在使用各个厂家物料时在各个工位的最佳焊接参数,从而指导生产操作。优化焊接工艺后,使用优化后的工艺生产三批产品,检测各项指标并与优化前的三批产品进行对比,确认优化后的工艺切实可行且达到优化目的。
[Abstract]:Non-#en0# multi-layer coextrusion film infusion bag (referred to as non-#en1# soft bag) is the most new packing form of large infusion at present, because the infusion adopts the completely closed infusion system. Only the external air compression bag can be smoothly dripped and pressurized to remove the danger of air pollution and air embolism. It is one of the healthiest transfusion packaging forms. Although the non-#en0# soft bag infusion products on the market meet the national quality standards, some of the products are prone to leakage during loading and unloading and back and forth handling. This is a major problem faced by product manufacturers. This is mainly due to the fact that non-#en0# soft bags are made from non-#en1# multilayer co-extrusion films, polypropylene interfaces and polypropylene composite covers are welded at high temperature. Some of the welding parts are fragile, and the breakage in the loading and unloading and handling process leads to leakage. And at present, there are many manufacturers of non-#en0# soft bags, there are no clear process parameters when using different materials. The non-PVC soft bag is produced by the automatic bag filling and sealing machine. The equipment position includes interface preheating, peripheral heating, interface welding. This topic is based on the use of different manufacturers of materials to adjust the welding die and make clear welding parameters, so as to optimize the welding process. Improve the quality of product welding. This topic in the interface preheating station, peripheral thermal station, interface welding station and mouth cover welding station first clear the mold assembly and adjustment requirements. Then the welding standard of each station is clear, and finally the effect test of different welding temperature is carried out according to the materials of different manufacturers in each station. Finally determine the best welding parameters in each station when using the materials of each manufacturer, so as to guide the production operation. After optimizing the welding process, use the optimized process to produce three batches of products. The indexes were tested and compared with the three batches of products before optimization, and the optimized process was confirmed to be feasible and to achieve the purpose of optimization.
