Small Spring for Agarbatti Making Machine

Small Spring for Agarbatti Making Machine :

• Function:

  The small spring in an agarbatti machine typically serves as a tension or compression component responsible for maintaining pressure, returning parts to their original positions, or controlling feed mechanisms. It plays a critical role in the stick feeding unit, powder pressing unit, or ejection mechanism depending on the specific machine design.

  Material:

  • Spring Steel (High Carbon Steel, Grade C60/C80)

  • Optional: Stainless Steel (SS304 or SS316) for corrosion resistance in humid environments

  • Finish: Zinc-plated or Black Oxide Coated (to prevent rust)

  ---

  ---

  Type of Spring:

  • Compression Spring (most commonly used in agarbatti machines)

  • In some designs: Torsion Spring or Extension Spring

  ---

  Load Capacity:

  • Designed to handle light to medium axial loads, typically in the range of 0.2 kg to 1.5 kg

  • Load-deflection characteristics engineered to match the machine’s feed rate and return force requirements

  ---

  Mounting Style:

  • Housed within a cylindrical guide or mounted on a rod

  • Preloaded or placed under slight compression when assembled to ensure consistent operation

  ---

  Applications Within the Machine:

  1. Stick Feeding Unit: Ensures constant pressure on the agarbatti sticks for automatic feeding into the pressing chamber.

  2. Pressing Die Return Mechanism: Helps the upper die return to its original position after pressing.

  3. Ejection System: Provides the force to eject the finished stick from the die cavity.

  4. Powder Compaction Unit: Assists in maintaining uniform pressure on the agarbatti mix.

  Performance Characteristics:

  • High cycle life (up to 100,000+ cycles depending on quality and maintenance)

  • Excellent fatigue resistance under repeated use

  • Maintains dimensional stability under working temperatures (typically up to 50–60°C in most environments)

  ---

  Maintenance:

  • Periodic inspection for corrosion, fatigue cracks, or loss of elasticity

  • Lubrication (if applicable) to reduce wear

  • Replace if length is permanently compressed or force drops below operational requirement
