Fully Automatic Nail Gluing Machine

Automatic Folding & Stitching Integrated Machine Overview

The fully automatic folding and stitching machine integrates paper feeding, folding, stitching, and output into one highly automated system. Controlled by a PLC and touch‑panel digital interface, it features dual‑servo drive synchronization, with accurate, efficient, and energy‑saving operation.
Automation covers every stage—from feeding, folding, gluing, and stitching to carton output. Average box length can reach 140 m/min, and folding speed can reach 50–60 boxes/min, improving productivity while reducing labor cost.

Feeding Section

1. Front feeding rack adjusts left and right synchronously for improved alignment accuracy.
2. Dual‑belt paper feeding system ensures stable sheet delivery; the feeding pressure is digitally regulated.
3. Imported guide shafts and bearings guarantee stable, durable performance.
4. Connected with the folding section through variable frequency control with design speed 0–150 m/min, feeding speed 0–140 m/min.
5. Front and side regulation plates are electrically adjustable for precise sheet alignment.

Folding and Gluing Section

1. The main motor features variable frequency control for stable and quiet operation.
2. Imported friction‑drive belts ensure smooth and automatic folding.
3. Stainless‑steel gluing system applies glue evenly with electrically adjustable right/left positions.
4. Equipped with upper / lower glue wheels and correction rollers for accurate folding.
5. Digital temperature and glue‑volume control maintain consistent coating.
6. PLC controls for real‑time synchronization between folding and feeding.
7. Built‑in alignment sensors achieve high‑speed, precise gluing and folding.
8. Energy‑saving design reduces adhesive consumption by ≥20%.

Stitching Section

1. Servo‑driven head lifting system increases stitching accuracy and box‑type transition speed.
2. Imported servo motors for high precision and reliable mechanical control.
3. Touch screen enables parameter switching (nails, spacing, head type, rear stopper) quickly and conveniently.
4. Controlled entirely through the PLC system for precise coordination between feeding and stitching.
5. Electrical rear stopper driven by step motor for more accurate adjustments.
6. Japanese‑made alloy cutter blades ensure wear resistance and long life.
7. Machine head structure made from hardened steel with CNC precision processing.
8. Optional single, dual, or manual stitching modes to suit various customer needs.
9. Carton size and nail spacing adjustment can be completed within one minute.
10. Mechanical speed reaches 800 nails/min, with stitch range adjustable 120–200 mm.
11. Stitch spacing: 20–120 mm, freely adjustable.
12. Glue roller gap electrically adjustable.
13. Built‑in transformer for voltage protection.
14. Automatic wire feeding system – 20 kg roll, improving uptime.

Counting and Stacking Section

1. Operated through PLC with digital display—easy setup, continuous counting, and automatic stacking.
2. Variable‑frequency main motor provides smooth and stable control.
3. Conveying and stacking speed adjustable 0–140 m/min.
4. Independent sensor control ensures accuracy and reliability.
5. Upper / lower conveying pressure bands maintain carton alignment for compact stacking.
6. Carton height adjustable ±50 mm.
7. Upper conveyor plate with lifting motor for height adjustment.
