Atmospheric Jig Dyeing Machine

SMD atmospheric jig dyeing machine cover a full range from small sample units to large-capacity models, ideal for small-batch, multi-variety dyeing tasks. Main models feature cloth roll diameters of Φ150mm, Φ600mm, Φ1200mm, Φ1400mm, and Φ1500mm. The outer shell is built with a sloped top, self-closing door frame, pneumatic opening/closing, and dual lifting cylinders. The top cover heating system is drip-proof and automatically stops when the door is opened. Dye tank heating options include direct steam and indirect steam heating. The ambient temperature model can be equipped with active cloth roll roller staggering function and external heat exchanger, with customizable functional options to meet process requirements.

1. Frame and Housing: Main supporting structure, typically made of stainless steel.

2. Two Fabric Rollers: Active drive rollers used for alternating fabric winding.

3. Guide Rollers: Guide the fabric for smooth movement, ensuring uniform tension.

4. Dyeing Tank (Liquid Tank): Stores the dye liquor, where the fabric is immersed. The tank is usually equipped with heating/cooling coils.

5. Tension Control System: Adjusts the torque of the fabric winding rollers via pneumatic or mechanical devices to control the fabric tension during operation.

6. Reversing System: Controls the automatic reverse movement of the fabric when a roll is full.

7. Circulation Pump and Feeding Tank: Used for circulating and mixing the dye liquor and automatically adding dyes and auxiliaries through pipelines.

Control System: Modern models are equipped with a PLC and touch screen for presetting and monitoring process parameters such as tension, speed, temperature, and number of passes.

1. Control Panel

This touchscreen control system is designed for ease of operation. All operational steps and real-time equipment statuses can be easily tracked through the display, and the program runs autonomously in line with pre-established settings.

2. Drive Equipment

Precise cloth speed adjustment is realized by means of vector control drive, and a non-blocking dynamic torque control approach is applied to maintain a uniform, constant tension level during the entire operation process.

Alternating Double Rollers

The fabric is wound onto roller A and then guided to roller B via the guide roller at the bottom of the V-shaped dye bath.

2

Stroke Definition

The fabric's movement from roller A → dye bath → roller B is called one "End" (single stroke).

3

Reciprocating Cycle

After roller B is fully wound, it automatically reverses direction, changing to roller B → roller A. This cycle repeats an even number of times until the required color depth is achieved.

4

Dye Adsorption

The main effect occurs during the residence and diffusion stage of the fabric on the rollers, rather than during the instantaneous immersion.
