2 Bowl Nut And Bolt Counting Packing Machine

The nut and bolt counting packing machine is a highly efficient automatic packaging machine designed for small fasteners such as nuts and bolts. It integrates automatic sorting, counting, printing and packaging functions, and is widely used in hardware, electronics, electrical appliances and other industries to improve production efficiency and reduce labor costs for enterprises.


  • Hardware manufacturing: automatic counting and packaging of screws and nuts of various specifications.
  • Electronic industry: accurate counting and packaging of electronic components and parts.
  • Auto parts: automatic packaging of small auto parts.
  • Others: suitable for counting and packaging needs of various small parts.


Dual-channel design: equipped with two independent vibration plates, each of which can be set separately to meet the counting requirements of screws of different specifications, greatly improving production efficiency.

High-precision counting: Using advanced fiber optic sensing technology to ensure that every screw can be accurately counted. The error rate is extremely low to ensure packaging quality

Intelligent control system: equipped with human-machine interface (HMI), easy to operate. Users can set parameters and monitor operations through the touch screen, supporting multiple counting and packaging modes。

Strong compatibility: Suitable for small parts such as screws and nuts of different sizes and materials. The flexible adjustment capabilities of the vibration plate and counting system enable it to meet a variety of production needs.

Stability and durability: The equipment has a solid structure and is made of high-quality materials to ensure long-term stable operation and durability.

High degree of automation: From feeding, counting, packaging to sealing, the whole process is automated, reducing manual intervention and improving production efficiency and stability.

Working principle

  1. Vibration plate feeding: Two vibration plates are responsible for bolts of different specifications, and the bolts are transported to the counting channel in an orderly manner through vibration.
  2. Counting system: Each vibration plate is equipped with an independent sensor and counting device. When the screw passes the counting point, the sensor accurately records the number.
  3. Central collection: The counted screws are collected to the packaging area through the guide rail.
  4. Packaging and sealing: The packaging machine automatically puts the counted screws into the packaging bag and seals it. The whole process is efficient and smooth.


  • Improve production efficiency: Multi-channel design and high degree of automation significantly improve production speed and reduce labor costs.
  • Ensure packaging quality: High-precision counting system ensures the accurate number of screws in each bag to avoid missing or overpacking.
  • Flexible and adaptable: It can be flexibly adjusted according to different production needs, with strong adaptability and a wide range of applications.

Two bowl nut and bolt counting packing machine can greatly improve production efficiency and reduce the labor cost of enterprises.
