The computerized jacquard faucet is a core component used in textile machinery to control the warp jacquard movement, and its high-speed operation and precise structure require extremely high operational safety. The following are the key safety precautions for computer jacquard faucets, covering operation, maintenance, and emergency response:

1. Safety check before operation

Equipment status confirmation

Power off check: Before turning on the machine, ensure that the jacquard faucet is in a power-off state (confirm that the control box is not powered by a voltage tester) to avoid mechanical injury caused by accidental startup.

Mechanical protection: Check whether the protective cover of the jacquard faucet (such as blade protective cover, transmission gear cover) is intact, without missing or loose parts;

; If the protective cover is damaged, it needs to be replaced or repaired immediately before operation. Lubrication system: Confirm that the lubricating oil level is within the normal range (usually 1/2~2/3 of the oil window) to avoid overheating and jamming of gears or bearings due to lack of oil.

Environmental safety

Cleanliness: Clean the yarn, flying flowers and other debris around and inside the jacquard faucet to prevent entanglement of moving parts (such as the frame and lifting knife) from causing malfunctions.

. Ventilation conditions: Ensure good ventilation around the equipment to avoid performance degradation or damage to electronic components (such as drivers and sensors) caused by high temperatures.

Personnel protection

Wear protective equipment: Operators should wear work hats (to prevent hair from getting tangled up), cut resistant gloves (when handling yarn), and dust masks (to reduce the inhalation of flying flowers).

.

Prohibit wearing accessories: Remove metal accessories such as watches, necklaces, earrings, etc., to avoid contact with moving parts that may cause scratches or equipment short circuits.

.

2. Safety regulations during operation

Prohibit unauthorized operations

Do not touch moving parts: When the jacquard faucet is running, it is strictly prohibited to touch high-speed moving parts such as the frame, lifting knife, gears, etc. with your hands to prevent cuts or injuries.

.

Avoid forced intervention: If the device stalls or makes abnormal noises, immediately press the emergency stop button (usually a red mushroom head button) instead of forcibly adjusting the position of the components by hand.

.

Parameter monitoring

Real time observation: Monitor the operating parameters of the jacquard faucet (such as speed, temperature, tension) through the control panel or display screen. If abnormal parameters are found (such as temperature exceeding 70 ℃, speed fluctuation>5%), the machine needs to be stopped for inspection.

.

Yarn tension control: Ensure uniform warp tension to avoid breakage of the lifting blade or deformation of the frame due to excessive tension, while insufficient tension may cause yarn entanglement.

.

Anti static measures

Grounding protection: Confirm that the metal shell of the jacquard faucet is reliably grounded through a wire (grounding resistance ≤ 4 Ω) to prevent static electricity accumulation from causing damage to electronic components or electric sparks.

.

Humidity control: Maintain the relative humidity in the workshop between 45% and 65% to reduce static electricity generation (dry environments can easily cause static discharge).

.

III. Maintenance and Overhaul Safety

Power outage maintenance

Complete power outage: Before performing any maintenance operation, the main power switch must be turned off and a warning sign reading "Do not turn on, someone is working" must be hung to prevent others from accidentally supplying power.

. Discharge treatment: If the jacquard faucet contains capacitive components (such as driver filter capacitors), wait for more than 5 minutes to ensure that the capacitors are discharged before conducting maintenance.

Component replacement and adjustment

Use special tools: When replacing components such as lifting knives and integrated frames, it is necessary to use the special tools provided by the manufacturer (such as torque wrenches and integrated frame adjustment gauges) to avoid component damage or installation deviation caused by improper tools.

.

Tightening torque control: According to the equipment manual, use a torque wrench to tighten the bolts (such as the fixing bolts of the frame with a torque of 10~12N · m) to prevent loosening or over tightening.

.

Cleaning and lubrication

Cleaning method: Use compressed air to blow away flying flowers and dust inside the jacquard faucet, and avoid wiping electronic components with a damp cloth (which may cause short circuits);

; If wiping is required, a dry cloth or specialized cleaning agent should be used. Lubrication cycle: According to the equipment manual, regularly add lubricating oil to gears, bearings, and other parts (such as every 500 hours), using the manufacturer's recommended model (such as ISO VG32 hydraulic oil).

IV. Emergency Handling and Safety Training

Common Malfunctions Emergency

Knife lifting fracture: Immediately press the emergency stop button to cut off the power supply;

; Clean up broken knife fragments to prevent scratching personnel or damaging other components; Replace the same specification lifting knife and adjust the tension.

Electronic component failure: If the driver alarms (such as overcurrent or overvoltage), power off first and then check the circuit connection;

; If the fault cannot be eliminated, it is necessary to contact professional maintenance personnel and do not disassemble the drive by yourself.

Safety Training

Operation Training: New employees must receive at least 40 hours of jacquard faucet operation training, including equipment structure, safety regulations, emergency response, etc. Only after passing the assessment can they operate independently.

.

Regular refresher training: Organize safety refresher training every 6 months to update operators' knowledge of equipment improvement or new safety functions (such as the use of new protective covers).

.

Safety Signs and Records

Labeling: Post safety warning signs (such as "High Voltage Danger" and "Do Not Touch") around the jacquard faucet, as well as operation flowcharts and emergency contact numbers.

.

Maintenance records: Establish equipment maintenance files, record information such as each maintenance time, replacement parts, and cause of faults, for easy traceability and analysis of potential safety issues.

.

V. Safety precautions for special scenarios

High temperature environment

If the workshop temperature exceeds 40 ℃, it is necessary to strengthen the heat dissipation of the jacquard faucet (such as adding fans or air conditioning cooling) to avoid damage to electronic components due to overheating.

.

Wet environment

In rainy season or workshops with humidity>80%, the electronic control box of the jacquard faucet needs to be treated with moisture-proof agents (such as adding moisture-proof agents and sealing strips) to prevent circuit short circuits.

.

Night operation

When working at night, it is necessary to ensure sufficient lighting around the jacquard faucet (illumination ≥ 300lux) to avoid operational errors caused by unclear visibility.

.

Summary

The safe use of computer jacquard faucets should follow the principle of "prevention first, standardized operation, and timely maintenance". Through strict safety inspections, operation monitoring, maintenance, and emergency response, the equipment failure rate and personnel injury risk can be significantly reduced.

. It is recommended that enterprises develop detailed safety operating procedures based on equipment manuals and industry standards (such as GB/T 19001 Quality Management System), and regularly organize safety drills to ensure that operators are proficient in safety skills.
