Pressure Flow Packing Machine with Visible Window - High-Efficiency Valve Bag Filling Equipment

Working Principle

1. Material is fed by gravity into the product feed inlet, and the storage bin’s visible window allows real-time observation of material status;

2. When a valve bag is placed on the discharge spout, a fill cycle is initiated automatically;

3. The butterfly inlet valve closes immediately, trapping the product in the pressure chamber;

4. Air generated by the positive displacement blower is directed primarily into the top of the pressure chamber, passes through the product and flows out the spout, carrying the product into the bag;

5. Once the bag achieves the preset filled weight, a cross pinch valve closes to prevent product from passing out the spout;

6. The air pressure in the pressure chamber is relieved, and the butterfly valve opens again to recharge the pressure chamber with materials for the next fill cycle;

7. The filled bag is discharged manually or with optional conveyor equipment, and the whole cycle can be repeated continuously.

Core Features

• Visible window design: Equipped with a visible window on the storage bin, customers can check the material level, flow status and residue in real time, facilitating timely material supplement and ensuring continuous production;

• Pressure flow filling: Adopts advanced pressure flow technology, matched with positive displacement blower, ensuring fast and uniform filling, suitable for flaked, powdery and granular materials with positive flow characteristics;

• High filling precision: Equipped with automatic electronic scale gross weighing filler, which simultaneously fills and weighs the product directly into the bag, ensuring filling precision and consistent product weight;

• Complete configuration: Integrates machine controls, electronic scale, dust collection device, bag clamp and other necessary components, no need for additional equipment investment;

• Wide applicability: Suitable for a variety of materials, including concrete, stucco, grout, sand, refractory materials, bentonite, TIO2, iron oxide, carbon black, plastic pellets, fertilizer and seeds;

• Stable and reliable: Adopts high-quality valves (butterfly valve, cross pinch valve) and blower, with stable performance, low failure rate and long service life;

• Easy operation: Simple control system, clear operation interface, operators can get started quickly without professional technical training;

• Customizable options: Custom options available upon request to meet the diverse production needs of different customers;

• Warranty guarantee: Provides 1 year limited warranty and perfect after-sales service, solving customer worries about equipment use and maintenance.
