The key to determining if a dyeing machine has completely cooled down is whether the overload protector has reset. If the protector resets automatically, the machine will restart after cooling; if it
Factors affecting reset time: 1. Overload protector type: Mechanical thermal relay: Relies on a bimetallic strip that bends to cut off power. It automatically resets after cooling, typically taking a
1. Immediately cut off power: Press the emergency stop button to disconnect the main power supply and ensure safety. 2. Troubleshoot the cause: Mechanical: Check the transmission system, tension devic
I. Core Judgment Methods 1. Current Monitoring: Use a clamp meter to measure the motor's operating current. If it consistently exceeds the rated current (usually indicated on the nameplate), an ov
I. Listen to the sound: Assess the machine's operating status. Normal: The motor and transmission components run smoothly without abnormal noise. Abnormal: Abnormal noise will be emitted when bear
I. Common Dyeing Defects and Solutions 1. Color Difference (Beginning-to-End Difference, Edge-to-Center Difference) Causes: Uneven dye concentration, temperature fluctuations, unstable fabric running
I. Common Dyeing Defects 1. Seam Marks: Darker areas appear at both ends of the silk fabric. Causes: The seam is too wide or thick; excessive tension; the guide silk is too short; or there is a signif
I. Safety Operating Procedures 1. Preparation for Loading: Operation must be stopped. Wet the fabric end with water and then smoothly attach it to the roller. Do not operate while the machine is runni
I. Abnormal Operating Status 1. Abnormal Sounds: Unusual noises such as metallic friction or impacts during operation indicate wear on bearings, gears, and other components. 2. Abnormal Temperature: A
I. Core Troubleshooting Approach and Principles 1. Safety First: Disconnect power, tag, lock, and ensure there is no pressure or high temperature before operation. 2. Systematic Approach: Start with s
I. Dyeing Process Issues 1. Overlapping Marks: Darker colors at both ends of the fabric, caused by excessively thick seams, excessive tension, or problems with the yarn guide. 2. Uneven Color at the E
I. Cleaning and Maintenance: Thoroughly remove residues and prevent contamination and corrosion. 1. External Cleaning: Wipe the machine surface with a soft cloth and neutral detergent, keeping it clea
