In the valve bag making machine sector, Gachn Group's new generation FK008-III valve bag making machine, with its numerous innovative technologies and superior performance, has become an industry leader. It not only breaks through traditional limitations in key processes such as bag making, transfer, bag opening, and conveying, but also demonstrates significant advantages in technical parameters and equipment configuration, providing businesses with an efficient, stable, and cost-effective production experience

Core Innovative Technologies Break Through Traditional Production Bottlenecks

Gachn Group's valve bag making machines feature innovative designs in several key mechanisms, effectively resolving numerous issues with traditional equipment.

In the bag transfer process, the Gachn Group utilizes a proprietary vacuum suction bag steering mechanism, enabling high-speed, vertical bag transfer for rapid and stable operation. Unlike the "claw-type" bag steering mechanisms used by other manufacturers, Gachn Group possesses its own core technology and intellectual property, avoiding patents held by renowned international equipment manufacturers and eliminating the risk of intellectual property infringement lawsuits.

The triangular bag opening mechanism is a further highlight, lacking consumable suction cups, significantly reducing ongoing maintenance costs. This mechanism utilizes a combination of negative pressure and a conveyor system to efficiently open the bag bottom while reducing noise and ensuring efficient and stable operation. Similarly, this proprietary core technology avoids international patents, eliminating the risk of intellectual property infringement lawsuits and providing peace of mind for manufacturers.

In terms of suction roller transfer, the bottom tape belt conveyors used by other valve bag making machines on the market are prone to bending, resulting in scrap. Furthermore, the higher the production speed, the more severe the kinking problem becomes. The belts also wear easily, making replacement difficult. Gachn Group's innovative suction roller conveyor mechanism is less prone to corner bending, significantly improving bag yields, enhancing equipment stability, and reducing production costs. This feature is unique to Gachn Group and is patented.

In addition, Gachn Group utilizes a professionally designed heat-sealing welding mechanism and unique technology, equipped with three hot air mechanisms, to ensure uniform air blowing and consistent dimensions. Servo-controlled switching of the air blow reversing axis allows for precise control of the welding on/off timing. Compared to other manufacturers' pneumatic cylinder control mechanisms, this system offers higher welding quality, precise adjustment of the air blow angle, and flexible adjustment of the heat seal width without requiring downtime, significantly enhancing production flexibility and efficiency.

Excellent Technical Parameters, Meeting Diverse Production Needs

The Gachn Group FK008-III valve bag making machine excels in bag making specifications and equipment parameters, adapting to diverse production needs.

It offers a wide range of bag specifications, with bag center length (L) ranging from 330-730 mm, bag width (W) from 300-620 mm, and bottom width (W1) from 80-120 mm, respectively. The valve opening length ranges from 80-200 mm.

The machine's specifications are equally impressive, with the main unit measuring 12.0 m (L) x 7.5 m (W) x 2.5 m (H), featuring a height adjustment mechanism at the bottom. The machine weighs approximately 17,000 kg. It utilizes a 3-phase, 380 Vac ±5%, 50 Hz, three-phase, five-wire system (CE standard), with an installed capacity of approximately 150 kW. The bag-making speed reaches a stable 130 bags/minute, with a maximum operating speed of 140 bags/minute.

Gachn Group's new-generation FK008-III valve bag bag-making machine integrates a visual inspection and waste removal system with core bag-making technology, creating a truly fully automated AI-powered closed-loop production system. Equipped with a 4K line-array infrared high-speed industrial camera and a black-and-white high-speed industrial camera, the visual inspection system accurately detects cosmetic defects in bags at a speed of 120 bags/minute. With a waste rejection rate of ≥96.5% and a false rejection rate of <0.15%, it enables real-time monitoring and intelligent screening of bag quality. Its detection logic is efficiently integrated with the core bag-making technology. When the visual system identifies a defective bag, a signal is instantly fed back to the bag-making unit's servo control system, triggering a cutting mechanism to precisely separate the defective bag. Simultaneously, the bag transfer unit's vacuum suction and dual servo drive systems immediately adjust the conveying rhythm to ensure that subsequent qualified bags are not affected.

Superior Equipment Configuration Ensures Stable and Efficient Operation.
