Core Technologies & Innovative Features

Six core advantages optimized for reconstituted tobacco processing, combining advanced domestic and international technologies.

Stepper Motor Precision Feed

Knife feed is driven by a stepper motor for stable and adjustable operation. The integral knife roll design facilitates maintenance and significantly improves assembly and cutting precision for long-term stability.

Adjustable Compression Angle

The upper chain compression angle can be adjusted according to material characteristics. Using a specific adjustment device, the compression angle can be set to 12°, 15°, or 18°.

Adjustable Pressure Technology

The compression unit utilizes a lever amplification principle with adjustable pressure. It precisely controls material density to ensure a tight "tobacco cake" structure, enhancing cutting quality.

Advanced Cylindrical Grinding

Uses cylindrical grinding to ensure linear contact between the grinding wheel and knife edge, maximizing efficiency. Stepper motor feed control paired with diamond dressing keeps blades extremely sharp.

Siemens S7-1500 Control

Powered by a Siemens S7-1500 PLC with remote I/O and Profinet bus for a layered control network. Supports networking with downstream machines and central control rooms for intelligent management.

Upgraded HMI

Comprehensive menus, robust recipe management, and parameter tracking. Real-time monitoring of knife/wheel usage, cut width, and cylinder pressure ensures intuitive operation.

Precision Mechanical Structure

SQ911A High Precision Integrated Knife Roll
High Precision Integrated Knife Roll

01 6-Knife Integrated Roll

The core component of the SQ911A. The knife roll body is a fully machined integrated component with excellent dynamic balance, equipped with 6 knives for smooth cutting.

  • Large Diameter: Theoretical diameter of ⌀600mm improves cutting inertia and stability.
  • Electric Feed: Uses a stepper motor drive mechanism for variable knife feed adjustment.
  • Smart Monitoring: Knife design length 102mm (effective 58.5mm). System tracks knife length and auto-stops when wear limit is reached.
SQ911A Independent Drive System
Independent Drive System

02 Independent Chain Drives

The conveyor system consists of the compression unit, upper chain, and lower chain systems. Advanced independent drive technology makes maintenance easier.

  • Servo Synchronization: Upper and lower chains are independently driven but strictly synchronized with the knife roll speed to ensure dynamic cut width accuracy.
  • Constant Gap Principle: Unique trajectory correction ensures the gap between the mouthpiece and knife remains constant as the upper mouthpiece moves.
  • Easy Maintenance: Equipped with special chain removal tools and central roller tensioning, adjustable via operation windows.
SQ911A Cylindrical Grinding System
Cylindrical Grinding System

03 High-Efficiency Grinder

Primary function is the reciprocating grinding of the continuously feeding knives and automatic dressing of the grinding wheel.

  • Cylindrical Grinding: Linear contact between wheel and edge ensures high grinding efficiency and cut quality.
  • Variable Frequency: Reciprocation speed is adjustable via VFD to perfectly match the knife feed rate.
  • Diamond Dressing: Equipped with a diamond dresser mechanism to automatically turn the wheel surface, ensuring a constant grinding circumference.

Safety & Protection

Comprehensive Safety

The SQ911A is equipped with a complete mechanical and electrical safety system to ensure operator and equipment safety.

  • Lower Mouthpiece Overload Protection (Shear Pin)
  • Mouthpiece Height Limit Protection
  • Head & Cover Interlock Protection
  • Auto-Stop on Knife/Wheel Exhaustion
  • Stop Feed on Power/Air Pressure Loss

Operation Control

  • Precise Speed Ratio Control Strict speed ratio control between knife roll and conveyor chains ensures uniform cut width.
  • Material Level Interlock High/Low level monitoring. Prevents start-up on low level and stops feeding on high level for automated operation.
  • Auto-Reverse Function Instant reverse control when the chain stops prevents material accumulation and facilitates cleaning.
  • Parametric Recipe Management Touchscreen storage and retrieval of process recipes to adapt to different reconstituted tobacco product requirements.
