Nantong Guoji Machinery Co., Ltd. specializes in the production and development of various types of plate coiling machines. Currently, according to customer requirements, there is a great demand for plate coiling machines with high precision and fast speed. According to this demand, automatic arc four-roll plate coiling machines have become the best-selling products of our company at present.

1. Structural design -- This machine adopts the rolling method of planetary oscillation, and the side roller moves around the upper roller in circular cycloid. Different models, using different mechanical geometry model and algorithm formula, in order to achieve the customer needs of the winding effect. The single Angle of the side roll of the traditional straight (oblique) line plate winder has certain requirements for the mechanical designer, the industry's rolling experience and the manufacturers' access threshold. (International enterprises such as DAVI of Italy and AKYAPAK of Turkey all adopt this type of structure)

2. Mechanical precision -- All joints of the side roller of the arc four rollers adopt the joint arm bearing connection mode. The tolerance of each node is within 0.02mm, and the cumulative accuracy tolerance of the whole machine is within 0.1mm.

3. Lubrication maintenance -- All swinging joints adopt oil-bearing seal design, the moving parts are in sealed environment, no lubrication maintenance is required, and the equipment accuracy can be maintained all the time. It will not be affected by the steel plate oxide layer, welding spatter and dust at the work site.

4. Rolling effect -- The clamping point between the upper roll and the planet movement is higher than that of the linear four-roll plate rolling machine of other brands, so better roundness and smaller rolling diameter can be obtained.

5. Electrical system -- self-developed third-generation automatic CNC bending system, suitable for rolling cylinders, cones, multi-segment arcs and special-shaped products.
