Engineered for top-tier performance, the SGR168B hthp jig dyeing machine comes in diverse models catering to both small-batch production and large-scale dyeing needs. Its core lineup includes four variants with cloth roll diameters measuring φ350mm, φ900mm, φ1200mm, and φ1400mm respectively. Constructed with a high-temperature high-pressure outer cylinder, the equipment runs at a working pressure of 3BAR and supports a maximum operating temperature of 140℃. Two φ150mm observation windows are mounted on the operator interface side, and a safety interlock switch is incorporated to prevent unsafe access to the pressure vessel during operation. In terms of functionality, this model matches the extended capabilities of standard normal-temperature dyeing machines. Rapid temperature regulation-both heating and cooling-is achieved through an externally mounted high-efficiency heat exchanger. The feeding cylinder is outfitted with a simulated liquid level sensor, which triggers real-time dye liquor supplementation whenever process parameters are adjusted, guaranteeing accurate bath ratio control. Condensed water accumulates at the cylinder bottom and is expelled automatically through a built-in valve. The machine adopts an automatic inner-outer cylinder separation mechanism: the inner cylinder stays stationary, while the outer cylinder is powered by the reducer's linear gear and travels steadily on a set of double guide rails.
Main Structural Components
1. Main Cylinder: Pressure-resistant stainless steel tank, including fabric storage tank.
2. Venturi Jet Pipe: Core component, determining fabric running speed and tension control.
3. Main Circulation Pump: Provides power for dye liquor circulation and jetting.
4. Heat Exchanger: Used for precise heating and rapid cooling of the dye liquor.
5. Filter System: Filters lint and impurities from the dye liquor, preventing clogging.
6. Automated Control System: Equipped with PLC and touch screen, precisely controlling all process parameters such as temperature, pressure, fabric speed, and material feeding.
7. Material Feeding System: Automated material tank, accurately and evenly injecting dyes and auxiliaries into the main cylinder.
Sampling Device: Allows for sampling and color matching without stopping the machine.
Working Principle
The fabric is smoothly wound onto a roll roller and placed into a dyeing vat. An appropriate amount of dye liquor and auxiliaries are added. The vat lid is then closed, and the heating and pressurizing system brings the vat to the set high-temperature and high-pressure conditions. The dye liquor continuously flows under the action of the circulation system, ensuring full contact with the fabric and achieving the dyeing process. After dyeing is complete, the pressure and temperature are reduced, the vat lid is opened, and the dyed fabric is removed.
Feature
1. Leveraging internationally advanced technologies, the equipment is equipped with AC frequency conversion transmission, PLC-based control, and data communication modules.
2. Closed-loop control is realized through accurate detection of actual fabric tension and linear speed, ensuring optimal process precision.
3. Touchscreen technology is incorporated to enable seamless and efficient human-machine interface interaction.
4. It comes with comprehensive automatic functions: automatic temperature regulation, fabric turning, lane recording, reversing, parking, and fabric handling.
5. The entire machine is fitted with a dye liquor circulation system that preserves uniform temperature and dye consistency. Additionally, a filtering device is integrated into the circulation loop to prevent pipeline blockages.
6. The machine is outfitted with practical auxiliary devices such as top cover lighting and fault warning lamps, making operation safe and maintenance hassle-free.
7. The drain valve, air chimney, and fabric outlet cross arm are all controlled by pneumatic systems for reliable operation.
8. Key components of the machine are imported products, which lay a solid foundation for stable and dependable performance.
9. Fully automated production process control allows for flexible combinations of various dyeing processes to satisfy different production requirements.
10. Cover opening is designed to be flexible and convenient, and the cylinder moves smoothly on the guide rails with minimal friction.
