Vertical material racks are the most widely used unwinding equipment in the stamping industry due to their wide variety, heavy bearing capacity and high degree of customization.

Although there are many kinds of vertical material racks, there are light material racks, heavy material racks and double-head material racks. However, the bearing principle is basically the same, and both of them adopt the expansion and contraction type drum to carry the coil materials.

The motor realizes the unwinding, and the expansion and contraction method has two types: the hand expansion mode and the oil pressure expansion mode depending on the weight of the load material.

However, in many cases, the vertical material frame is used in the process of unwinding the small material roll. If the hand is used to expand and contract, it will inevitably increase the work intensity of the staff and the work efficiency is low.

If the hydraulic expansion and contraction method is adopted, a hydraulic station is required to increase the production cost.

Whether it is more economical, affordable, and time-saving and labor-saving material rack equipment for small material roll unwinding; in order to meet customer needs.

Based on the traditional vertical material frame, Ruihui Machinery has specially developed and produced a new type of light screw material frame, which uses transmission cone teeth, transmission screw, rotary body, support rod, supporting material plate and worm gear belt. The new transmission structure type of clutch.

Expansion through the electric air shaft, fully automatic expansion without the need to add hydraulic stations, rotating cylinders, additional cost, economical, time-saving and labor-saving, small footprint, light weight, simple installation, Easy to shift, easy to operate and so on.

The new light screw material frame work mainly has two processes of expansion and unwinding:

When the feeding is up and down, the rotating handle is rotated, and the positioning pin slides to the rotating body to abut, so that the rotating body is positioned in the circumferential direction, and the driving cone teeth are separated from the rotating body.

The light-type screw material frame motor is started to drive the spindle to rotate, and the main shaft drives the transmission cone to rotate. The transmission cone teeth drive the transmission screw to rotate, so that the supporting material plate expands outward, and the material coil is tightened.

When the coil is used, the rotating handle is rotated, and the positioning pin slides away from the rotating body to separate the rotating body from the positioning pin, and the driving cone teeth re-engage with the rotating body.

The motor is started to drive the spindle to rotate, and the main shaft drives the rotating body and the driving screw to rotate integrally, thereby realizing automatic unwinding of the light material coil.
