Working Principle
Different feeding mechanisms are adapted according to the particle characteristics of materials. For materials with larger particles, impeller feeding is adopted— the impeller rotates to scoop materials from the storage bin and push them to the filling port. For materials with smaller particles (such as dry-mixed mortar components), screw feeding is used, where spiral blades transport materials along the screw shaft to the filling channel, ensuring stable transportation of materials with different properties.
After the packaging starts, the motor drives the impeller or screw to rotate at high speed. At the same time, the compressed air in the filling tube assists in enhancing material fluidity, quickly pressing the materials into the valve bag. This stage fills at a high flow rate, rapidly completing most of the filling volume and significantly shortening the basic packaging time.
When the material weight reaches approximately 70% of the target value, the control system automatically triggers "deceleration adjustment" — the feeding motor slows down to reduce the material conveying volume, the compressed air pressure decreases simultaneously, and the cylinder mechanism reduces the cross-sectional area of the filling tube to slow down the material flow rate. When the weight reaches the preset value, the feeding and air flow stop completely, achieving a weighing accuracy of within ±0.5%.
Product Features
Through the design of a large-diameter filling tube and a high-speed initial feeding mechanism, more bags can be packed per unit time.
Integrating high-precision weighing sensors, variable-frequency motor speed regulation, air pressure adjustment and filling channel diameter change technology, the packaging error is strictly controlled within ±0.5% (some high-end models can achieve even lower error). This ensures uniform weight of each bag of products, which not only meets quality control standards but also avoids market disputes caused by weight deviation.
A dust collection hood is installed at the filling outlet, which can capture the dust escaping during the filling process, reducing dust emissions by more than 90%. At the same time, a closed filling process is adopted to reduce material leakage and noise diffusion, fully complying with national green production standards and improving the workshop working environment.
It can not only handle dry-mixed mortar (including ordinary masonry mortar, thermal insulation mortar, waterproof mortar, etc.) but also be compatible with various powder and granular materials in industries such as building materials, mining and chemical engineering. By adjusting feeding speed, air flow parameters, etc., it can adapt to the packaging needs of materials with different specific gravities and particle sizes, featuring strong versatility.
Adopting a computer control system, packaging parameters (such as weight and speed) can be preset to realize full-process automation including automatic bag clamping, automatic filling, automatic weighing and automatic bag releasing. Workers only need to load empty bags and monitor the equipment, greatly reducing manual intervention, cutting labor costs and avoiding human operation errors.

Frequently Asked Questions (FAQ)
What feeding methods are available for this valve port packing machine?
The machine offers versatile feeding options including screw, gas, vibration, and impeller feeding. The feeding mechanism is selected based on your material's particle characteristics, such as impeller feeding for larger particles and screw feeding for smaller particles like dry-mixed mortar.
What is the packing weight range and hourly capacity?
The machine is designed to handle packing weights of 5~10kg, 10~25kg, and 25~50kg. It features a packaging capacity of 120 to 360 bags per hour, depending on the material and configuration.
How accurate is the weighing and filling system?
The overall packing error is strictly controlled within ≤0.3%FS. Through a phased control process (rapid initial filling followed by deceleration adjustment and air pressure reduction), the machine achieves a final weighing accuracy of within ±0.5%.
Does the machine help in controlling workshop dust and pollution?
Yes. The machine features an environmentally friendly design with a dust collection hood at the filling outlet, which captures escaping dust and reduces emissions by more than 90%. The closed filling process also minimizes material leakage and noise.
