Working Principles
Working Principle of Rotor Pump: The rotor pump is primarily composed of a pair of synchronously rotating rotors (such as gear rotors, cam rotors, etc.). These rotors spin within the pump body and transport liquids by periodically changing the volume of the pump cavity. Take a gear rotor pump as an example: two meshing gears rotate inside the pump casing, drawing liquid into the meshing area of the gears. As the gears turn, the liquid is conveyed to the outlet through the space between the gears and the pump casing. In the servo rotor pump fukubukuro seafood filling machine, seafood fillings are transported from the storage hopper to the filling head via the rotor pump.
Principle of Servo Control: The servo motor precisely controls the rotational speed, direction, and angle of the rotor pump, thereby accurately regulating the conveying volume of the fillings and the filling speed. For instance, when filling fukubukuro of different specifications, the filling volume for each cycle can be precisely controlled by adjusting the parameters of the servo motor to achieve high-precision filling. When the container reaches the filling position, the valve of the filling head opens, and the fillings flow into the fukubukuro skin under the pressure of the pump. The filling volume can be accurately controlled by adjusting the valve opening time or the pump's rotational speed.
Structural Features
Filling Conveying System: Comprises a hopper, servo rotor pump, and metering device. The hopper stores seafood fillings; the servo rotor pump transfers the fillings from the hopper to the metering device, which—under the control of the servo system—precisely regulates the filling volume for each cycle.
Filling Mechanism: Mainly consists of a filling head, lifting device, and valve. The filling head moves up and down via the lifting device. When the fukubukuro skin is in position, the filling head descends, the valve opens, and the fillings are injected into the fukubukuro skin under the pressure of the rotor pump. After filling is complete, the valve closes, and the filling head rises.
Fukubukuro Skin Conveying and Positioning System: Typically includes a conveyor belt and positioning fixtures. The conveyor belt sequentially transports fukubukuro skins to the filling position, while the positioning fixtures ensure accurate positioning during filling to prevent misalignment of the fillings.
Control System: Generally uses a PLC controller combined with a servo driver. It enables automated control of the filling machine, including functions such as setting filling volume, adjusting filling speed, controlling fukubukuro skin conveying speed, and fault alarm. The operation is simple and convenient, enhancing production efficiency and product quality.
Purchase Considerations
Production Capacity: Select equipment with appropriate filling speed and output based on your production needs. For example, large food factories may require machines capable of filling thousands of fukubukuro per hour, while small workshops can opt for models with lower output.
Filling Accuracy: For fukubukuro seafood filling machines, filling accuracy is critical as it directly affects product quality and taste. Choose equipment with high filling accuracy, such as those with an error margin controlled within ±1%.
Material and Hygiene: The equipment’s materials must comply with food hygiene standards. Parts in contact with the fillings should be made of 304 or 316L stainless steel for easy cleaning and disinfection, preventing bacterial growth.
Automation Level: Highly automated filling machines reduce manual operations and improve production efficiency and product quality stability. Depending on actual needs, select equipment with functions such as automatic feeding, automatic filling, and automatic sealing.
After-Sales Service: Choose manufacturers with excellent after-sales service to ensure timely maintenance and repair in case of equipment failures, minimizing downtime and ensuring smooth production.
