STRUCTURAL COMPOSITION
Weighing System: It is usually composed of two high - precision weighing sensors and supporting weighing hoppers, etc., which can accurately weigh the materials. Each weighing unit can work independently or cooperate with each other to ensure the accuracy and stability of weighing.
Material Conveying System: It includes the feeding conveyor belt, discharging conveyor belt, etc. The feeding conveyor belt transports the materials to be packaged to the weighing position. After weighing, the discharging conveyor belt transports the packaged products to the next process. Generally, a speed - regulating device is installed on the conveyor belt, which can adjust the conveying speed according to production requirements.
Packaging System: It is mainly composed of a packaging forming mechanism, a heat - sealing device, a cutting knife, etc. The packaging forming mechanism can shape the rolled packaging material into the required packaging bag shape. The heat - sealing device seals the packaging bag, and the cutting knife cuts the continuous packaging material into individual packaging bags.
Control System: It adopts an advanced PLC controller and human - machine interface. Operators can easily set various parameters on the touch screen, such as weighing range, packaging speed, sealing time and temperature, etc. The control system also has functions of data recording and statistics, which can monitor and analyze production data in real - time.
WORKING PRINCIPLE
Weighing Process: Materials enter the dual - scale automatic packaging machine through the feeding port and are evenly distributed into two weighing hoppers. The weighing sensors measure the weight of the materials in the hoppers in real - time and convert the weight signals into electrical signals, which are then transmitted to the control system. The control system compares the data from the two weighing sensors according to the preset target weight. When the set weight is reached, the supply of materials is stopped.
Packaging Process: After weighing is completed, the materials fall into the pre - formed packaging bags below. Driven by the traction mechanism, the packaging material is continuously conveyed forward. Through processes such as bag - making, sealing, and cutting, one packaging cycle is completed. At the same time, the discharging conveyor belt sends out the packaged products, which then enter subsequent processes such as boxing and palletizing.
PERFORMANCE CHARACTERISTICS
High weighing accuracy: The dual - scale design can further improve the weighing accuracy through comparison and complementarity. Generally, the weighing error can be controlled within ±1 gram, meeting the requirements of industries with high demands for product weight accuracy.
Fast packaging speed: The two scales work alternately and cooperate with an efficient packaging system, greatly improving the packaging efficiency. It can complete 15 - 60 packaging operations per minute. The specific speed depends on the product specifications and packaging requirements.
Good stability: With high - quality components and advanced manufacturing processes, the equipment has a solid structure and operates stably and reliably. It is equipped with complete fault - alarm and protection functions, which can promptly detect and handle problems during the equipment operation, reducing downtime.
High flexibility: Parameters such as the weighing range, packaging size, and packaging form can be flexibly adjusted according to different material characteristics and packaging requirements. It can adapt to various packaging materials, such as plastic films and composite films, and can also achieve multiple packaging forms, such as three - side sealing, four - side sealing, and back - sealing.
