The GQ-90L packaging scale is an electromechanical integration device featuring a dual independent measurement control system that incorporates multiple cutting-edge technologies. With performance metrics leading among domestic counterparts, it is designed for automated quantitative packaging of granular materials in production lines across the sugar, salt, food, feed, and chemical industries.
I. Structure and Working Principle
The entire system consists of two components: the mechanical part and the electrical control part. The electrical control part comprises pressure sensors and an electrical control box; the mechanical part includes a multi-stage feeding mechanism, a force-measuring hopper with weighing function, a bag-clamping mechanism, and a frame structure.
During operation, under the controllers command, the discharge door first closes to initiate automatic peeling and zeroing before activating the feeding mechanism. Materials continuously flow into the measuring hopper, where a pressure sensor converts their weight into corresponding electrical signals transmitted to the controller. The controller displays the material weight value on its interface and sequentially outputs control signals based on preset parameters, enabling the feeding mechanism to dispense materials at three speeds (fast, medium, slow). Previously using a three-stage pneumatic cylinder system caused significant equipment vibration; this has now been replaced with a single-stage separation mechanism combined with vibration-assisted feeding, ensuring precise quantitative dosing without shaking or damaging material integrity. Upon completion of feeding, all components close: the lower discharge door opens to allow materials to be bagged via gravity through the bag-clamping cylinder. After discharge, the discharge door closes while the bag-clamping mechanism opens to release bags. A manual switch controls the mechanisms opening/closing states for bag insertion operations, with the controller only triggering bag-filling commands when the clamping mechanism is engaged.
II. Characteristics
It employs an independent measurement system with no mutual interference and features rapid packaging speed.
The measurement control system employs high-precision force sensors, a display controller with a conversion rate of 500 cycles per second, and a specially designed multi-stage feeding mechanism, combined with advanced control algorithms, ensuring exceptional measurement accuracy and stability.
The operation is simple: the operator only needs to place the bag and activate the bag-clamping switch, while all processes—including feeding, filling, and unloading—are automatically performed by the weighing scale.
It features a manual control switch that allows manual operation of the feeding and discharging mechanisms, facilitating waste removal.
