Open Mouth Bagging Machine – Wuxi Jianying A4 and A5 series – are specifically designed for quantitative filling of open-mouth small bags weighing 20–50 kg. Unlike tonnage bag models, they feature a compact design with minimal space occupation, making them ideal for handling fine powders, granules, and sheet materials, as well as woven bags, paper-plastic composite bags, and inner-membrane composite open pouches. These machines can operate semi-automatically independently or be integrated with conveyors, sealing machines, and palletizing robots to form fully automated small-pouch packaging lines.

Feature and Application
The gravity-type Open Mouth Bagging Machine comprises: a gravity arc-door feeding system (specifically designed for granules) and a dual-arc-door feeding system with coarse and fine-stage feeding, featuring minimal impact and no clogging, suitable for highly fluid particles such as urea and plastic pellets; the discharge channel is widened to prevent bridging, enabling rapid bag filling without material obstruction.
Spiral variable-frequency feeding system (standard for powder materials): Small-diameter spirals are designed for fine powders, with variable-speed regulation enabling rapid coarse filling followed by precise supplementary dosing; the material hopper can be equipped with a vibration arch-breaking motor to prevent powder bridging and uneven discharge, while its polished inner surface resists powder adhesion.
The open mouth bagging equipment series features high-precision imported weighing sensors combined with an integrated load-bearing bag platform, demonstrating significant advantages in powder processing conditions. Equipped with a self-developed dynamic weight compensation algorithm, it real-time compensates for material drop impacts, density fluctuations, and variations in empty bag weights, ensuring stable packaging weight over extended continuous operation periods.
Pneumatic bag clamping and dust removal system: The annular pneumatic clamp automatically secures the bag opening for a tight seal, ensuring no powder leakage during filling; compatible with bags of varying widths with one-touch adjustment of clamping travel. Equipped with a standard integrated negative-pressure dust collection flange that connects to dust collectors for centralized dust recovery, achieving workshop dust concentrations well below industry standards and powder loss below 0.5%.
Intelligent control system: 7-inch industrial touchscreen; packaging capacities of 20/25/40/50 kg; one-touch switching without mechanical adjustment; visualizable adjustable parameters for coarse and fine feeding speeds; automatic shift output statistics; audible and visual alarms for deviation; self-diagnostic records for bag shortages, material blockages, or insufficient air supply.
