As the core equipment of modern textile industry, high-speed jacquard machine integrates microelectronics technology, electromagnetic technology and CAD/CAM system to achieve high-speed jacquard without patterns, significantly improving production efficiency and product quality. The following is its standardized usage process and key precautions:
1、 Equipment installation and debugging
INSTALLATION REQUIREMENTS
The jacquard machine needs to be installed above the loom, with the height determined by the number of needles, width, and assembly mode, ensuring that the angle between the thread and the mesh plate is ≥ 60 °.
The load-bearing frame needs to be stable, and the center of the through plate and the center of the reed should be centered to avoid uneven stress.
Debugging steps
Electrical personnel install jacquard controllers, communication cables, and color selection cables to complete equipment power on.
Call the sample card file to test whether communication with the weaving machine is normal and ensure that data transmission is error free.
2、 Operation process
Startup and interface operation
Startup interface: Display system version, number of needles, arrangement method, and serial number. Press any key to enter the weaving interface.
Weaving interface: Real time display of weft number, shift, output, speed, and task information. Parameter settings, file selection, and testing operations can be performed through the function keys (F1-F5).
Parameter settings
Latitude number and shift: Move the cursor with the up and down keys, press the confirm key to modify the parameter values, and confirm again after modification.
Task and speed: Set the production plan and real-time speed, and automatically shut down after the task is completed.
Pattern file management
File selection: Read the pattern file from the system or USB drive, select it, and press the confirm button to weave it.
File deletion and erasure: Delete or clear useless files to free up storage space.
Testing and Maintenance
Memory testing: Check the memory status of the interface board, which takes about 45 seconds.
Driver board testing: Display the status of each driver board (O is normal, X is faulty), locate the faulty driver board.
Electromagnetic valve testing: Check the status of each solenoid valve to ensure accurate operation of the jacquard machine.
3、 Operation monitoring and maintenance
Real time monitoring
View the memory, hard drive, communication, and cable status through the status interface, and display the specific cable number when there is a fault.
When the power supply of the faucet is below 12.5V, an alarm will sound and it needs to be repaired in a timely manner.
Routine maintenance
Lubricating oil replacement: After the first 1-3 months, replace the synthetic gear oil every 3000 hours or once a year.
Filter ventilation rate: It is strictly prohibited to use the equipment when it is below 70% or when the temperature of the component box exceeds 60 ℃.
Cleaning operation: When cleaning the surrounding area, it is necessary to keep the power on to avoid secondary pollution caused by flying flowers.
Fault handling
During maintenance, the power must be turned off to prevent damage to the controller.
It is strictly prohibited to cross the safety fence, remove the guardrail crossbar, or hang the gantry at will to ensure safe operation.
4、 Safety regulations
operation safety
Before starting, confirm that there are no obstacles around the device, and be slow and careful when going up and down stairs to prevent slipping.
Tools must not be placed randomly to avoid accidents caused by falling off during operation.
Maintenance safety
After moving the safety barrier, it should be promptly restored to ensure complete protection of the equipment.
After maintenance, the machine needs to run at a slow speed for at least 2 seconds before switching to fast mode.
Emergency Management
When the system malfunctions, the red fault light on the panel flashes, and the machine needs to be stopped immediately for inspection.
When the green light of the host is normal and does not flash, it indicates a motherboard malfunction and requires contacting professional personnel for repair.
5、 Efficient production techniques
optimization parameter
Adjust the number of needles, arrangement, and time interval according to fabric requirements to ensure efficient operation of the jacquard machine.
Use permission passwords to modify key parameters to prevent accidental operations.
data management
Regularly backup pattern files to avoid data loss.
When deleting useless files, it is necessary to confirm whether they have been overwritten to prevent accidental deletion of important data.
Team collaboration
During weaving, two people need to work together, one is a weaver and the other is a warp guide, to ensure a smooth production process.
Summary: The use of high-speed jacquard machines requires strict adherence to installation and debugging, operation procedures, operation monitoring, and safety regulations. Production efficiency is improved through parameter optimization and data management, while daily maintenance and team collaboration are emphasized to ensure long-term stable operation of the equipment.
