What is SH2000A weft feeder? How do they work?

The SH2000A weft feeder is a highly renowned "national pride" product in the textile industry. It is primarily installed on various medium- and high-speed rapier looms or shuttle looms. If the loom is the hardworking "weaver," then this device is the clever "assistant" responsible for neatly organizing and feeding the tangled yarn.

⋙ Introduction to the SH2000A Weft Feeder

Domestic Pioneer: It was one of the first domestically produced weft feeders to achieve automatic variable frequency speed control, breaking the previous reliance on imported high-end equipment.
Compact Design: Its design is quite refined and space-saving, yet it operates very reliably and is less prone to malfunctions.
Wide Applicability: Whether weaving lightweight silk or thick fabrics, the SH2000A weft feeder can be adjusted to accommodate yarns of different thicknesses.

⋙ How does it work?

This machine's working logic is very user-friendly, like a "perceptive" conveyor:
Automatic Yarn Intake: The internal motor rotates the yarn winding arm, "swallowing" the yarn from the large yarn cone and neatly winding it onto the smooth yarn storage drum.
Intelligent Variable Frequency Control: This is the most impressive feature of the SH2000A weft feeder. It incorporates variable frequency technology, automatically adjusting its winding speed based on the loom's weaving speed. If the loom is working fast, it winds quickly; if the loom slows down, it also slows down accordingly.
Precise Monitoring: It is equipped with several sensing points. It monitors the yarn inventory on the drum: if there is too much yarn, it stops; if the loom is about to run out of yarn, it quickly accelerates to replenish the supply.
Gentle Delivery: When the loom needs yarn, the yarn slides off the drum. The tension ring at the outlet ensures that the yarn is pulled out with very even force. This prevents uneven tension in the woven fabric, avoiding areas that are too loose or too tight.

⋙ Why do people love using it?

Worry-free operation: Because it has automatic speed control, workers don't need to frequently manually adjust switches or knobs; the machine handles it itself.
Energy-saving: The permanent magnet motor provides strong power but consumes little energy, saving significant electricity costs during prolonged operation.
Protects yarn: Its surface is polished very smoothly, preventing delicate yarn from fraying or breaking.
