Pneumatic Double-side High Foot Opening Knitting Machine

A Pneumatic Double-side High Foot Opening Knitting Machine typically refers to an advanced knitting machine designed for producing knitted fabrics with specific features like high foot openings (greater space under the machine for easy operation) and pneumatic mechanisms for enhanced precision and performance.

Here's a general specification list you might find for such machines:

1. Machine Type: Pneumatic Double-side High Foot Opening Knitting Machine

Model: Various models based on the manufacturer and specific needs (e.g., single or double jersey knitting, jacquard, rib, etc.)

2. Knitting Mechanism:

Knitting Type: Circular knitting

Needles: Typically 12 to 48 gauge (can vary depending on fabric type)

Needle Type: Single or double needle bar system for complex knitting patterns

Cam System: Advanced cam system for precise stitch formation

3. Pneumatic Features:

Pneumatic Control: Used for fabric tension, loop formation, and yarn feeding adjustments.

Pneumatic Cylinder for Loop Formation: Ensures precise stitch loop formation for a smoother, more consistent fabric.

Automatic Yarn Cutting: Pneumatic-controlled yarn cutting for precise finishing.

4. Foot Opening:

Foot Height: High foot opening (may range from 60 mm to 150 mm) for easy access under the machine to change yarns, conduct maintenance, or make adjustments.

Foot Movement: Pneumatically operated for smooth and consistent foot opening.

5. Speed:

Machine Speed: Varies from 20 to 30 RPM (revolutions per minute) depending on fabric type and yarn characteristics.

Yarn Feed Speed: Controlled and adjustable, can range between 50 to 120 m/min.

6. Fabric Types:

Product Types: Suitable for manufacturing various fabrics including jerseys, interlock, rib, mesh, and other knitted fabrics.

Fabric Width: Varies based on the specific machine (e.g., 24", 30", 36" widths).

Fabric Finishing: Pneumatic-driven mechanisms to ensure proper fabric width and edge finishing.

7. Knitting Width:

Knitting Diameter: Typically between 20" and 48" (depending on model).

8. Yarn Type:

Yarn: Suitable for knitting with cotton, wool, polyester, nylon, acrylic, and blended yarns.

Yarn Feeder: Pneumatic yarn feeding for precise and consistent yarn delivery.

9. Automation:

Automatic Lubrication System: Pneumatic lubrication to reduce friction and wear, leading to more consistent performance and less maintenance.

Automatic Stop Function: Stops the machine in case of yarn breakage or other operational failures.

10. Control Panel:

PLC (Programmable Logic Controller): Allows easy adjustments for tension, speed, and stitch formation.

Touchscreen Interface: For user-friendly operation and setup adjustments.

Error Diagnostics: Built-in system for identifying problems like yarn breakage, excessive tension, etc.

11. Power and Consumption:

Power Supply: 380V ± 10%, 3-phase, 50/60Hz (can vary depending on the region).

Power Consumption: Typically around 4 to 7 kW, depending on machine model and configuration.

Compressed Air Requirement: Pneumatic systems require a constant supply of compressed air (around 0.5-0.8 MPa).

12. Maintenance and Durability:

Self-diagnostic System: Helps in quick identification and troubleshooting of issues.

Maintenance Interval: Based on usage and environment (regular maintenance for pneumatic systems to ensure performance).

13. Safety Features:

Emergency Stop Button: For safe operation in case of a malfunction.

Safety Guards: For protection during high-speed operations.

14. Additional Features:

Pneumatic Tensioning Device: For controlling yarn tension and minimizing defects.

Automatic Stitch Length Adjustment: Pneumatic-controlled automatic stitch adjustment for different fabric requirements.
