Solution

Packaging equipment mainly consists of five parts: weighing, pneumatic, control, electric, and mechanical. The weighing part mainly includes weighing sensors, weighing hoppers, and twin-screw feeders; the pneumatic part includes air sources, cylinders, and air supply pipes; the control part includes PLCs, plug-in bus busbars, universal switches, and control buttons; the electric part includes solenoid valves; and the mechanical part includes feeding hoppers and hopper gates

Process Flow

Product preparation and delivery

       Materials enter the packaging line via manual or automated conveying systems (such as conveyor belts and vibratory feeders). They are then oriented by a sorting machine to ensure accuracy in subsequent packaging processes

Product loading

       A counting device (such as a photoelectric sensor) controls the quantity, and then a solenoid valve is controlled by a direct-insertion manifold to load the material into the packaging box by the clamp

Packaging sealing

       The cardboard box is sealed with glue

Auxiliary processing

       Labeling machines affix product information labels or barcodes

Detection

       Check the seal integrity, label position, printing quality, and net weight

Packing and palletizing

       The controller controls the solenoid valves via a plug-in bus busbar, causing the clamps to clamp the products and stack them according to the set pattern

Solution

This packaging equipment uses a PLC + plug-in bus bus board, which can control the operation of the solenoid valve through plug-in. The main body also comes with 16 power supplies and 16 DI inputs, which can supply power to the limit switches at both ends of the cylinder and read the limit switch signals

Application effect

Reduce costs and make the equipment more aesthetically pleasing

       The plug-in bus busbar eliminates the need for external output modules; the solenoid valve can be directly plugged into the bus bus busbar, reducing the labor costs for electricians in wiring. Limit switches can also be wired locally without needing to be connected to the input module, resulting in cleaner wiring and easier installation
