Zhejiang Ruitai Packaging Machinery Co., Ltd. is one of the leading manufacturers and suppliers of automatic pre-opened rolling bag making machine in China. With abundant experience, we warmly welcome you to wholesale premium automatic pre-opened rolling bag making machine from our factory. We also accept customized orders.
Automatic pre-opened rolling bag making machine. Engineered to process plain or custom-printed PE film into bottom-seal bags, this dedicated converter serves parcel delivery and industrial packaging sectors. Eleven independent patents safeguard its core technologies. Its full automation suite encompasses digital length regulation, visual tracking, auto pre-opening, film rewinding, punch processing, no-feed emergency halt and real-time tension management. Automatic pre-opened rolling bag making machine, It stands as a premium, future-ready production system in the packaging machinery field.
Automatic pre-opened rolling bag making machine has the following advantages:
1. Loading part: ① First, cylinders perform rapid lifting to avoid wasted feeding time. Meanwhile, the structure bears working loads and keeps film stable during operation, which makes automatic control easy to operate. With a 750mm maximum unwinding diameter for film rolls, manual labor for lifting is fully saved. ② Once materials run short or get damaged, an automatic shutdown will be initiated. This avoids the production of unqualified items and saves operators from tedious re-threading work, cutting down overall time and labor expenditure. You can pick from two modes: one is touch shutdown (A), the other is roll diameter calculation shutdown (B).
2. Host part: High-performance domestic PLC serves as the control core, with all programs being our exclusive intellectual property. Touch-based parameter setting brings great convenience to operators. The system monitors production processes continuously and views electronic fault data. Analog feed synchronization makes feeding speed fully coordinated with other working steps. The front-rear dual servo structure prevents film stretching during conveying. One servo controls the lamination of two film layers, while the second drives the post-cutter rubber roller. Precise film delivery control achieves standard high-precision cutting and hot pressing.
3. Discharge section: This intelligent system counts finished items and production batches automatically. You may set unlimited length or quantity alarm points for auto stop and hold. The dwell time can be specified directly on the operating screen.
