YK-600 Pre-opened Courier Bag Roll Making Machine

Machine operation video：

 

· Suitable for HDPE, LDPE tubular film to produce plain or color‑printed pre‑opened courier bags.

· Effectively reduce sealing stretching phenomenon of film bags during machine operation.

· Achieve 1‑2 mm bag welding width to enhance bag welding strength.

· Computer PLC control with servo‑motor feeding.

· Photo‑electric eye tracks color marks for accurate graphic positioning on printed films.

· Bag‑making length and speed set via computer, generating fewer waste scraps for easy operation.

· Full‑automatic functions: tooth opening, 3.0‑mode feeding, sealing‑cutting, counting, rewinding and alarm reminder.

· Pneumatic loading, air‑expansion shaft and magnetic‑powder tension for stable unwinding.

· Automatic web deviation correction and tension adjustment.

· Dual‑servo motor dual‑rubber‑roller non‑stretch feeding system.

· Servo‑controlled copper cutter vertical movement; copper cutter fixed by linear copper sleeve.

· Automatic rewinding roll‑diameter‑linked tension control.

· Auto‑alarm and auto‑stop when material runs out.

1. Anti‑stretching Sealing Performance

Optimized mechanical structure avoids bag sealing stretching in high‑speed running, keeping sealing edges flat and neat for courier bags.

2. Reinforced Welding Strength

1‑2 mm hot welding width improves sealing firmness, preventing bag seam cracking for logistics usage.

3. Dual‑servo Non‑stretch Feeding

Dual‑servo plus dual rubber roller feeding avoids film pulling, keeps consistent bag dimension and uniform film thickness.

4. Precise Color‑mark Positioning

Photoelectric eye tracking ensures accurate printing pattern registration for color‑printed bags.

5. Intelligent PLC Touch‑screen Operation

Easy setting for bag length and production speed, lower skill requirement for operators and less material waste.

6. Stable Full‑line Tension Control

Pneumatic loading, air‑expansion shaft, magnetic‑powder tension and automatic deviation correction keep film flat without wrinkle or offset.

7. Reliable Safety Protection

No‑material auto‑alarm & auto‑stop prevent idle running and reduce unexpected loss.

8. Neat Finished Roll Output

Rewinding with automatic roll‑diameter‑based tension control produces tight, tidy roll goods, convenient for storage, transport and further conversion.
