1工艺要求立式成型制袋式包装机可完成制袋、纵封(搭接或对接)、充填、封口及切断等工作,其结构见图1。薄膜经多道导辊引上翻领成型器,由纵封器封合定形,搭接或对接成圆筒状,计量装置计量后的物料由加料斗通过加料管导入袋底,横封器在封底同时拉袋向下,并对前一满袋封口,再在两袋间切断使之分开。为了能使包装袋连续塑封,需要控制拉膜电动机和放卷电动机以指定的速度进行工作。
1 process requirements Vertical forming bag making machine can be completed bagging, vertical sealing (lap or docking), filling, sealing and cutting work, the structure shown in Figure 1. The film is introduced into the lapel former by a plurality of guide rollers and is sealed and set by the vertical sealing device. The materials measured by the metering device are introduced into the bag bottom through the feeding hopper through the feeding hopper. The horizontal sealing device is sealed on the back cover At the same time pull the bag down, and the previous one full bag seal, then cut off between the two bags to separate. In order to continuously wrap the package, the pull-film motor and the unwinding motor need to be controlled to work at the specified speed.
