The weighing Feeding machine is a material conveying system that uses air flow as power to transport materials through a pipeline system. It is a technology that conveys solid granular materials through air flow. It adopts a closed pipeline for conveying, which can effectively prevent moisture and debris from contaminating the materials. It is fully sealed, pollution-free for conveying, and the conveying pipeline layout is flexible. The conveying pipeline can be arranged according to the specific terrain, and materials can be loaded in one place. Then, unloading is carried out at multiple locations, which is suitable for centralized transportation to one place from multiple locations. The feeding points can be one or several, and remote operation can be achieved. During the transportation process, multiple process operations can be carried out simultaneously, such as drying, etc.

The feeding machine mainly uses weighing instruments and PLC as the auxiliary control system. The computer human-machine interface displays the proportioning parameters (formula) and monitors and records real-time data. In the automatic control mode, click the "Start" button for automatic batching on the front process screen or the "Start" button on the front control cabinet, and the weighing instrument will open the material valve according to the set formula. If the system detects that a certain batching valve is not closed, an alarm will be triggered and the system will enter a pause state. Each weighing valve is equipped with a lead time for its speed. When the control instrument detects that the weight has reached the set value, the Electronic scale will subtract the lead time, and the control weighing instrument will close the feed valve. The lead time can be manually corrected or automatically corrected to ensure that the weighing instrument controls the batching scale to achieve the set target value for each batching accuracy.

Structural composition of the weighing and feeding machine

The feeding system is responsible for evenly and stably feeding the materials into the conveying pipeline. It is usually installed at the beginning of the system. By using the negative or positive pressure formed by the air source device, the material and air are mixed in a certain proportion and then sent into the pipeline. Common feeding devices include rotary valves, screw conveyors, rotary Feeders, screw pumps, bin pumps and Venturi nozzles, etc. The selection of the feeding device should be comprehensively considered based on the characteristics of the materials and the conveying requirements.

The air source device is the power core of the adjustable weighing and feeding machine system, providing the air flow power required for conveying. Common air source equipment includes Roots blowers, compressors, centrifugal blowers and water ring vacuum pumps, etc. These devices can generate a stable airflow, providing sufficient power for the transportation of materials.

The control system is the "brain" of the adjustable weighing and feeding machine system, responsible for monitoring and controlling the entire system. Through control devices such as programmable controllers, precise regulation and control of parameters like air flow velocity, feeding volume, and system pressure can be achieved, ensuring the stable operation of the system and meeting production requirements.

The conveying pipeline is the channel through which materials are conveyed after being mixed with the airflow. It is made of wear-resistant and corrosion-resistant materials to ensure that the materials will not be contaminated or damaged during the conveying process. The diameter, shape and length of the pipeline will be designed based on the characteristics of the conveyed materials and the conveying volume. In addition, the piping system may also include some accessory pipe fittings, such as valves, elbows, expansion joints, etc., which are used to regulate the airflow and pipe connections.

The dust removal system is crucial to the environmental performance of the adjustable weighing and feeding machine system. It is responsible for handling the dust and waste gas generated during the conveying process to ensure that the emissions meet environmental protection requirements. A dust removal system typically consists of components such as dust collectors, fans, and exhaust pipes. According to the different material characteristics and environmental protection requirements, different dust removal equipment and technical solutions can be selected.
