The material rack is also known as the uncoiler. Its function is to realize the unloading and unwinding of the sheet material coil, which is the necessary equipment for the automation of stamping processing and production.

There are many types of material racks, but the traditional ones that are suitable for high-speed unwinding are flat electronic feeders (also known as disc racks).

However, the flat electronic feeder can only be used for the unwinding of thin and narrow materials, and the bearing capacity is small, and the outer diameter of the reel is low, which has become increasingly unable to meet the needs of modern high-speed stamping.

High-speed heavy-duty material frame, this new material frame has both traditional heavy-duty material and large load capacity, wide application range (thin plate, medium plate and heavy plate coil can be used), high degree of customization (load weight, outside diameter of the coil) The advantages of the path can be customized.

It can also realize high-speed unwinding (unwinding speed up to 30m/min), which is the most excellent high-speed unwinding equipment at present.

Compared with traditional heavy-duty material racks, high-speed heavy-duty material racks have greatly improved the appearance and structure of the models. The biggest change is the improvement of the expansion and contraction mechanism (using double-expanding shrinkage rolls) and the increase of crank locking devices. At the same time, the sliding sleeve with the inclined wedge surface was eliminated.

The high-speed heavy-duty material frame center pull rod drives the fan-shaped support material plate under the action of the spring's top pressure, so that it slides along the inclined wedge surface-crank locking device to maintain the reel of the reel.

Because of the double expansion and contraction structure, the volume expansion and contraction range can be about twice as large as that of the single expansion and contraction reel, and at the same time, the gap between the fan-shaped trays is large.
