Core Drive and Motion Components
Spindle and Bearing Assemblies:Replace spindles with excessive wear and main bearings with clearances exceeding limits by threefold; simultaneously replace bearing housing seals to eliminate radial runout and abnormal noise, thereby restoring the equipment's core rotational precision.
Precision Drive Assemblies: Replace scored ball screws and drive gears with tooth thickness wear exceeding one-third; replace aged or deformed timing belts/chains to eliminate transmission stutter and step loss, ensuring tufting positioning accuracy.
Guide Rails and Slider Blocks: Replace linear guide rails and slider blocks exhibiting deep scratches or excessive wear; recalibrate rail parallelism to eliminate "stick-slip" (jerky motion) and vibration during operation.
Core Brush-Forming Actuators
Tufting Head Assembly: Replace worn tufting needles and bristle-separating needle wheels; replace deformed bristle-feeding rails to resolve process issues such as uneven tufting density, dropped needles, and bristle jams.
Drilling/Cutting Components: Replace dulled high-speed drilling spindles and worn drill chucks; replace bristle cutters with chipped edges to ensure tufting hole diameter precision and bristle length tolerance compliance.
Brush Roller/Pressure Wheel Assembly: Replace main brush rollers with bristle wear exceeding one-third; replace aged pressure wheels (rubber rollers) that have lost elasticity to restore stability in workpiece clamping and feeding.
