Product Description

Product Description

 The machine is a high-performance semi-automatic machine designed for eco-friendly square bottom paper bags. It processes blank or printed paper rolls (e.g., kraft paper, food-grade paper) in one continuous cycle, covering center gluing, printing tracking, fixed-length cutting, bottom creasing, folding, gluing, forming, and finishing. Equipped with Mitsubishi servo systems, Sick photoelectric eyes, and a Willon touchscreen, it ensures precise size tracking and easy operation. Hydraulic loading, auto tension control, and servo deviation correction optimize efficiency. With a production speed of 30-120 bags/min, it handles bags 220-450mm wide and 380-760mm long (80-150gsm paper). Ideal for snack, bread, and dried fruit bags, it combines reliability and versatility for diverse packaging needs.

Product Details

Unloading Magnetic Powder Brake: The Core of Stable Tension

Deviation Correcting Sensor: The Intelligent Guardian of Precise Alignment

This machine is equipped with an unloading magnetic powder brake system, whose core function is to precisely control the tension of the paper during the unwinding process, ensuring that the paper is always transported smoothly and evenly.
 
In high-speed printing or processing scenarios, stable tension can effectively prevent issues like stretching, wrinkling, or tearing of the paper. It provides a reliable foundation for subsequent processes such as die-cutting and printing, making it ideal for handling various industrial papers including kraft paper and coated paper.

The integrated deviation correcting sensor is a key component for ensuring accurate material conveying. It can detect the edge position of the paper in real time. As soon as it detects any material deviation, it immediately sends a signal to the control system, which drives the actuator to quickly adjust the material position, ensuring the paper always stays on the preset central path.
 
This function is critical for production processes requiring high-precision overprinting or die-cutting, as it effectively reduces scrap rates caused by material misalignment and significantly improves production efficiency and finished product quality.

Gusset Inner Folding Disc and Pressure Guide Rollers: The Precision Folding Core

Paper Sleeve Cutting Unit: Efficiently Converting Sleeves into Individual Bags

The gusset inner folding disc and pressure guide rollers are responsible for shaping the paper into the characteristic bottom gusset of the bag. The precisely engineered folding discs crease the paper, while the pressure guide rollers ensure consistent tension and alignment throughout the process. This results in neat, uniform gussets that enhance the bag's structural stability and capacity, laying the foundation for a high-quality finished product.
 

The paper sleeve cutting unit uses sharp, precision blades to automatically cut the continuous paper sleeve into individual bag blanks. This high-speed cutting process ensures clean, straight edges and consistent bag dimensions, eliminating manual trimming and reducing waste. By integrating seamlessly with upstream and downstream processes, it significantly boosts overall production efficiency and ensures a steady flow of uniform bag components ready for final assembly.
