What is sanhe weft accumulator? How do they work?

The Sanhe weft accumulator is a very common "yarn manager" in textile workshops. Installed between the loom and the large yarn bobbin, it is specifically responsible for straightening the yarn, ensuring that the loom operates smoothly without jamming or breaking the yarn.
You can imagine it as an **"intelligent buffer warehouse."**

● Main Components of the Sanhe Weft Accumulator

To understand how it works, let's look at its key "parts":
• High-efficiency motor: This is its power source, hidden inside the machine casing. It drives the winding arm to rotate rapidly, drawing the yarn from the large bobbin.
• Yarn storage drum: This is a stable cylindrical body. The drawn yarn is neatly wound around it in layers, waiting to enter the loom.
• Sensing probe: This is the machine's "eyes." It constantly monitors whether there is enough yarn on the drum. If there is too little, it tells the motor to speed up; if there is too much, it tells the motor to stop and rest.
• Yarn separation mechanism: Its function is to separate the wound yarn slightly to prevent them from overlapping or tangling.
• Tension adjustment ring: At the exit where the yarn is about to enter the loom, there is a device that adjusts the tension. It ensures that the yarn comes out at just the right tension, neither too loose nor too tight.

● How does the Sanhe Weft Accumulator work?

Its working process is actually very straightforward, mainly in three steps:
"Receiving" and "Storing": When the loom is working, the demand for yarn is "bursting." To avoid directly pulling on the large yarn bobbin, the Sanhe weft accumulator's motor rotates at a constant speed, pulling the yarn from the large bobbin in advance and neatly winding it onto its storage drum. In this way, the drum always stores a certain amount of "reserve yarn."
Intelligent Monitoring: The sensing probe on the machine constantly detects how many turns of yarn are stored on the drum. Sanhe's weft accumulator is very sensitive and can automatically adjust its winding speed according to the speed of the loom. If the loom runs fast, the yarn unwinds quickly; when the loom stops, it also rests, never wasting energy.
Smooth "delivery": When the loom needs yarn, the yarn slides smoothly off the drum. Because the drum surface is very smooth, and with the help of the tension adjustment ring, the force with which the yarn enters the loom is very even. This is like driving on a smooth highway without bumps, so the yarn won't break easily.

● Why use this equipment?

In actual production, the Sanhe weft accumulator performs very stably. It not only ensures that the woven fabric is flat and without defects, but also reduces the trouble of downtime caused by yarn breakage. For textile factories, this not only saves labor but also greatly improves the efficiency of fabric production.
