V. Process Details (Fully Automatic, No Manual Intervention Required)
- Startup and Debugging: Preheat for 5-10 minutes after startup, set bag length, heat sealing temperature (120-180℃, adjusted according to packaging materials), counting quantity and packaging speed through the touch screen, thread the film and debug the bag maker, cutter and color mark tracking to complete the startup preparation of the hardware screw packaging machine;
- Automatic Feeding: Pour screws into the Marchi customized vibrating plate, high-frequency vibration makes screws arrange directionally and discharge one by one, and send them to the counting area through the conveying track to avoid screw entanglement and jamming, ensuring smooth feeding of the hardware screw packaging machine;
- Accurate Counting: Fiber optic sensors count screws one by one, and after reaching the set quantity, a blanking signal is triggered, and screws fall accurately into the formed bag through the chain bucket slideway, reflecting the core counting advantage of the hardware screw packaging machine;
- Bag Making and Filling: Roll film is automatically formed into corresponding bag types (three-side seal/back seal/four-side seal) by the bag maker, and screw filling is completed synchronously to avoid material splashing and improve the packaging efficiency of the hardware screw packaging machine;
- Sealing and Coding: Heat sealing device seals the bag mouth, and completes date, specification and batch number coding synchronously, cutter cuts into independent finished bags, realizing integrated packaging operation of the hardware screw packaging machine;
- Finished Product Output: Finished bags are sent to the collection area via conveyor belt, which can be directly connected to subsequent boxing processes. The whole process is automated without manual sorting and sealing, highlighting the unmanned advantage of the hardware screw packaging machine.
VI. Explosion-Proof / Anti-Oxidation Adaptation
- Anti-Oxidation: Standard reinforced sealing design of packaging film, optional Marchi vacuum nitrogen filling module (vacuum pumping + high-purity nitrogen filling to create an oxygen-free environment), matched with aluminum foil composite film, effectively isolating oxygen and water vapor, preventing screws from rusting and oxidation, extending the shelf life to 18-24 months, suitable for anti-oxidation packaging needs of hardware screw packaging machines;
- Explosion-Proof: Equipment body adopts anti-static material, electrical system meets explosion-proof standards (Exd II BT3). Aiming at static electricity generated by screw friction in dry environment, equipped with static elimination device to avoid potential safety hazards caused by dust accumulation, meeting the requirements of explosion-proof hardware screw packaging machines for hardware processing workshops.
