HDS Series Automatic Weighing & Bagging Machine
Our HDS automatic bagging machine supports both valve bags and open mouth bags, equipped with self-developed intelligent weighing control system. It realizes full automatic procedures including auto feeding, precision weighing, pneumatic bag clamping, quantitative filling and finished bag conveying.
This weigh filler works for all kinds of powder and granular bulk materials, fully replacing manual weighing and filling. It ensures consistent bag weight and complies with international weighing inspection standards. Widely adopted by manufacturers in grain & oil, chemical, construction, mining and feed industries. The machine can work alone or be integrated with other equipment to build a fully automatic packaging production line for mass production.

Machine Structure
The whole machine consists of six core modular parts for easy installation and on-site maintenance:
- Top buffer silo
Stably store incoming materials to avoid weighing deviation caused by uneven material flow
- Two-stage gravity feeder
Coarse & fine dual-speed feeding design to reduce impact error from falling materials
- High precision load cell set
Dust-proof & impact-resistant for long-term industrial operation
- Pneumatic bag clamp unit
Automatically clamps and releases empty bags
- Intelligent control cabinet
Digital display shows real-time bag weight and operating parameters
- Bottom bag support conveyor
Directly transport filled bags to bag sewing machine
Compact overall layout. Staff can complete assembly, wiring and connection to your existing production line without complicated modification.
Key Machine Benefits
- Stable Weighing Accuracy, Cut Material Waste
Two-speed feeding plus closed-loop weighing algorithm counteracts weight impact error. Weighing accuracy meets international industrial filling standards. Effectively avoid underweight or overweight bags, lower raw material waste, keep uniform finished bag weight and easily pass third-party metering inspection.
- Full Automatic Operation, Reduce Labor Cost
Operators only need to sleeve empty bags. The machine automatically finishes feeding, weighing, filling and bag dropping. A single unit can replace 2–3 packing workers, with standard output of 300–600 bags per hour, matching high-volume production workshops perfectly.
- Heavy-duty Frame, Stable Performance Under Harsh Conditions
The frame is made of thickened carbon steel with anti-corrosion spray coating. All pneumatic components are dustproof and waterproof, and load cells resist dust and collision. It can run continuously in high-dust factories such as dry mortar plants, chemical powder workshops and mineral processing plants, featuring low failure rate, simple daily maintenance and longer service life.
- Wide Material Adaptability, Adjustable Weight Range
Workers can switch packaging weight from 10kg to 50kg by simply adjusting parameters on the control panel, no mechanical disassembly required. Compatible with ultra-fine powder, regular powder, hard granules and light flocculent materials. Custom 304 stainless steel sanitary version is available for food and pharmaceutical industries.
