Working Principle
The valve port packing machine completes material packaging through a highly automated and precise operation process, with the core focusing on "differentiated feeding + phased control" to achieve efficient and accurate filling. The specific process is as follows:
Feeding Method Selection
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.
Rapid Initial Filling
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.
Precise Final Control
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
Efficient Filling
Suitable for large-scale production. Through the design of a large-diameter filling tube and a high-speed initial feeding mechanism, more bags can be packed per unit time.
Controllable Precision
Ensuring product consistency. 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.
Environmentally Friendly
Reducing production pollution. 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.
Flexible Adaptability
Covering various materials. 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.
Automated Operation
Reducing labor costs. 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)
Q
What is the packing capacity and weight range of this machine?
The machine features a capacity of 120 to 360 bags per hour. It supports adjustable packing weight specifications including 5~10kg, 10~25kg, and 25~50kg.
Q
How does the machine ensure weighing and packing accuracy?
The packing error is strictly controlled within ≤0.3%FS. This is achieved by utilizing high-precision weighing sensors combined with a phased control system that automatically slows down feeding and reduces air flow when the weight reaches approximately 70% of the target value.
Q
What feeding methods are available, and how do I choose one?
The machine supports screw, gas, vibration, and impeller feeding methods. The method is selected based on material characteristics: for example, impeller feeding is ideal for larger particles, while screw feeding is preferred for smaller particles like dry-mixed mortar components.
Q
Does the machine have dust control features for green production?
Yes, a dust collection hood is installed at the filling outlet to capture escaping dust, reducing dust emissions by more than 90%. Combined with a closed filling process, it significantly reduces material leakage and noise, meeting green production standards.
