High speed jacquard machine is a core equipment used in the textile industry for efficient production of complex patterned fabrics. Its working principle integrates precision machinery, electronic control, and computer programming technology. The following is a step-by-step analysis of its core working principle:
1. Pattern data input and storage
Electronic Jacquard System:
Convert the pattern into digital signals through specialized software (such as CAD/CAM textile design software) and store them in the controller.
Supports high complexity:
It can handle complex patterns with millions of stitches or more, and supports fine designs such as gradient and three-dimensional jacquard.
2. Jacquard device control
Electromagnetic drive technology:
Using high response electromagnets or servo motors, the lifting and lowering of each warp yarn is controlled by electronic signals.
Independent control unit:
Each warp yarn corresponds to a control unit (such as crochet hooks, blades, etc.), achieving millimeter level precision control.
3. Weaving cycle process
Opening stage:
The jacquard device quickly lifts specific warp yarns based on pattern data to form a weaving loop, with a speed of thousands of times per minute.
Insertion stage:
The weft yarn (through a rapier, jet or shuttle) passes through the shuttle at high speed and interweaves with the warp yarn.
Weaving and coiling:
The reed seat tightens the weft yarn to the appropriate density, and the fabric roller synchronously rolls the fabric.
4. Key technologies for high-speed operation
Dynamic response optimization:
Using predictive algorithms to compensate for mechanical inertia, ensuring synchronization between the jacquard motion and the main motion of the loom.
Lightweight design:
Lightweight materials such as carbon fiber and aluminum alloy reduce vibration and improve stability.
Intelligent cooling system:
Forced air cooling or liquid cooling modules prevent electromagnetic overheating and support continuous high load operation.
5. Automation and intelligent upgrading
Online monitoring:
Integrated tension sensor and yarn breakage detector, providing real-time feedback on warp yarn status.
Adaptive adjustment:
Automatically calibrate the jacquard height based on fabric density, reducing manual intervention.
Remote maintenance:
Support remote diagnosis of the Internet of Things, quickly update pattern data or system firmware.
6. Application scenarios and advantages
Applicable fields:
High end home textiles (such as silk duvet covers), fashion fabrics (such as jacquard silk), and industrial textiles (such as automotive interiors).
Efficiency improvement:
Compared to traditional mechanical jacquard machines, the speed has increased by 30% -50%, and the time for changing patterns has been reduced to a few minutes.
Flexibility:
Support small batch and multi variety production, adapt to fast fashion and customized needs.
