Automated paper bag machines are integrated industrial equipment that completes automatic paper feeding, gluing, folding, forming and optional rope attaching in one continuous process, based on servo-driven motion control and PLC intelligent control systems, capable of mass producing paper packaging bags across multiple material and size specifications. As a core solution in the environmental packaging machinery sector, it has become an indispensable technical support for the digital transformation and industrial upgrading of global paper packaging production lines.
To meet diverse industry and working condition requirements, Wenzhou Ruizhi Machinery Co., Ltd. offers three mainstream series of automated paper bag machines, with customizable solutions for special scenarios:
1. Pointed-bottom paper bag machines: High-precision standard series, suitable for food packaging factories, baking plants and fast food chain packaging suppliers, with core features including servo numerical control mold adjustment and compatibility with oil-proof laminated paper.
2. Square-bottom paper bag machines: High-speed production series, suitable for supermarket and apparel shopping bag manufacturing, with core features including integrated dust suction system and stable production of thick paper materials.
3. Handle paper bag machines: High-end customization series, suitable for gift and luxury brand packaging, with core features including automatic rope attaching and compatibility with 180-350g thick art card paper.
The products are designed with core principles of high reliability, high precision, easy maintenance and long service life, fully considering the harsh working conditions of industrial production scenarios. The company strictly follows full lifecycle reliability design standards, providing clients with stable, low-maintenance and cost-effective technical solutions.
The core working principle of automated paper bag machines is based on servo-driven synchronous motion control, integrated with photoelectric detection and automatic fault diagnosis systems. The complete implementation workflow is as follows:
1. Automatic paper feeding system: Precisely conveys paper materials of different weights, with photoelectric sensors detecting alignment to avoid offset during production.
2. PLC control system: Coordinates the synchronous operation of gluing, bottom folding and forming stations, with numerical control mold adjustment to quickly switch bag specifications.
3. Finished product output: Automatically detects defective products, while a dust-free waste suction system cleans paper scraps to maintain a clean production environment.
The system architecture is optimized with modular design to improve performance, stability and scenario adaptability. Core modules include:
1. Imported servo drive module: Equipped with ABB, Lenze and Rexroth precision transmission components, ensuring transmission accuracy and 24-hour continuous operation stability.
2. Intelligent detection module: Integrated with SICK, Baumer photoelectric sensors, reducing paper jam and detection failure faults by 87% compared to conventional equipment.
3. Remote diagnosis module: Supports 24-hour fault warning and remote technical support, reducing offline on-site repair frequency by 85%.
Compared to conventional single-function paper bag machines, the technology achieves core breakthroughs addressing long-standing industry pain points:
1. Conventional equipment requires over 1 hour for mold adjustment, while the new series reduces mold change time to 10 minutes, improving production efficiency by 30%.
2. Conventional equipment has a defect rate of over 6%, while the new series reduces the defect rate to below 0.7%, cutting raw material waste by 15%.
3. Conventional production lines require multiple devices to complete all processes, while a single new machine replaces 3 single-function devices, reducing factory space occupation by 40 square meters.
