Description
Automatic Weighing Counting Hardware Packing Machine

This automatic packaging machine combines weighing and counting dual measuring system, specially customized for small bulk metal hardware accessories including screws, bolts, nuts, rivets and furniture fasteners. It adopts vibrating storage hopper feeding matched with magnetic lifting conveyor to achieve uninterrupted automatic feeding, supports compound plastic film back sealing bag making, suitable for mass continuous packaging of hardware manufacturing factories.
Machine Configuration & Technical Specifications

Working feeding principle: Large vibrating storage hopper conveys raw materials via vibration, magnetic elevator transports hardware parts to weighing box for rough weighing, counting vibration tray supplements tiny quantity difference to ensure accurate piece count and weight for each finished bag.
Machine Structural Details & Factory Production Workshop

Core Machine Advantages & Structure Features
- Large capacity vibrating storage bin with shock absorption springs, realize long-time continuous feeding without frequent manual material adding
- Magnetic lifting material conveyor, stable transportation for metal small parts, effectively avoid material jamming and blockage
- Human-machine touch screen PLC control system, freely set bag length, target weight and packing speed, equipped with emergency stop button for operation safety
- Integrated vertical film unwinding frame, automatic film pulling, bag forming, heat sealing and cutting all-in-one mechanism
- Outfeed conveyor for finished packaging bags, convenient for manual collection or docking with subsequent automatic boxing production line
- All material contact components adopt stainless steel material, anti-rust, corrosion resistant and easy to clean for metal hardware processing environment
Full Automatic Packing Production Process
- Raw hardware materials are poured into large vibrating storage hopper for buffering and storage
- Vibration bin evenly discharges metal parts to magnetic lifting elevator
- Magnetic elevator upward conveys materials into precision weighing box for rough weight measurement
- Vibration counting tray supplements small quantity of parts to correct weight deviation and guarantee accurate piece number
- Measured hardware materials fall into pre-formed plastic film bag
- Machine automatically pulls roll film, shapes bag, seals back edge and cuts finished bag
- Sealed packaging bag falls onto outfeed conveyor and outputs to collection area
