１、泡罩成型 1. Blister molding 根据泡罩成型是ＰＶＣ薄膜（硬片）加热后通过模具并利用压缩空气或真空成型为所需要形状、大小的泡罩的原理，因此当成型出的泡罩出现问题时需要从以下几方面着手解决： According to the molding blister is a PVC film (film) after heating through the mold and the use of compressed air or vacuum forming bubble principle required shape and size, so when the bubble forming problems of need to be addressed from the following aspects: （１） ＰＶＣ薄膜（硬片）是否为合格产品； (1) PVC film (film) is a qualified product; （２） 加热装置的温度是否过高或过低； (2) whether the temperature of the heating device is too high or too low; （３） 加热装置的表面是否粘连ＰＶＣ； (3) whether the surface of the heating device is adhered to PVC; （４） 成型模具是否合格，成型孔洞是否光滑，气孔是否通畅； (4) whether the molding die is qualified, whether the molding hole is smooth and the stoma is unobstructed; （５） 成型模具的冷却系统是否工作正常、有效； (5) whether the cooling system of the die is working properly and effectively; （６） 滚筒式负压成型的真空度、排气速率能否达到正常值，管路有无非正常损耗； (6) the vacuum degree and the exhaust rate of the roller negative pressure molding can reach the normal value, and the pipeline has no more than normal consumption; ２、热压封合 2, hot sealing 在滚筒式铝塑泡罩包装的热压封合过程中，ＰＶＣ带与铝箔是由相互平行的滚筒状热封辊和网纹辊在一定温度和压力作用下作啮合式对滚来完成热压封合的。热封辊和网纹辊的接触为线性接触，所需要的压力相对较小。 In the drum type blister packaging heat sealing process, PVC belt and foil is composed of a cylinder shaped heat parallel sealing roller and roller under certain temperature and pressure under the effect of mesh type of roll to complete the heat sealing. The contact between the heat sealing roller and the anilox roller is linear contact, and the required pressure is relatively small. 在平板式铝塑泡罩包装的热压封合过程中，ＰＶＣ带与铝箔是由相互平行的平板状热封板和网纹板在一定温度和压力作用下在同一平面内来完成热压封合的。热封板和网纹板的接触为面状接触，所需要的压力相对较大。 In a plate type blister packaging heat sealing process, PVC belt and foil is composed of planar parallel heat sealing plate and anilox plate at a certain temperature and pressure in the same plane to complete the heat sealing. The contact between the heat seal plate and the checkered plate is surface contact, and the required pressure is relatively large. 不论是滚筒式还是平板式热压封合，当出现热封网纹不清晰、网纹深浅不一、热合时ＰＶＣ带跑位造成硌泡等问题时需要从以下几方面着手解决： Whether the drum type or plate type heat sealing, when heat sealing is not clear, reticulate reticulate shades, heat PVC with movement caused by global issues such as GE needs to be dealt with from the following aspects: （１） 铝箔是否为合格产品，热合面是否涂有符合要求的热溶胶； (1) whether the aluminum foil for qualified products, sealing surface is coated with hot melt adhesive meets the requirements; （２） 加热装置的温度是否过高或过低； (2) whether the temperature of the heating device is too high or too low; （３） ＰＶＣ带或铝箔的运行是否有非正常的阻力； (3) is there any abnormal resistance in the operation of PVC belt or aluminum foil?; （４） 热封模具是否合格，表面是否平整、光滑，ＰＶＣ带上成型出的泡罩能否顺利套入热封辊（板）的孔洞内；（５）网纹辊（板）上的网纹是否纹路清晰、深浅一致； (4) heat sealing mold is qualified, the surface is smooth, smooth, PVC belt is formed on the bubble can be smoothly set into the heat sealing roller (plate) of the hole; (5) the roller (board) on the net is clear lines, consistent depth; （６） 热封模具的冷却系统是否工作正常、有效； (6) whether the cooling system of the heat sealing die is working properly and effectively; |
