Technical Field

The invention belongs to the technical field of foil winding machine equipment, and particularly relates to a winding pressing device for foil winding equipment and a winding method of a foil strip coil.

Background

Because foil is around the machine when coiling foil strip coil, need have the compression roller to roll extrusion all the time and wind the surface at the foil, firstly compress tightly current layer foil strip on one deck foil strip in the field, furthest's elimination foil strip layer and the space between the layer makes the foil strip material of coiling out roll more compactlyer, avoids artifical later stage to fill it as far as possible. And secondly, when the foil tape is cut off after the winding of the coil is finished, the phenomenon that the foil tape coil 12 loosens and separates when the wound coil loses tension is avoided. However, since the foil coil often has special shapes such as oval and rectangular products, i.e. the cross section of the foil coil is oval or rectangular, the pressing device is required to adapt to the change of the cross section diameter when the non-circular cross-section coil rotates, so as to perform shape-following rolling action. This adds more difficulty to the compacting function in the winding.

At present, a winding and pressing device adopted by most foil winding machines in the market is a simple structure with a straight arm connected with a press roller. The structure only plays a role in winding and pressing in the winding process of the circular foil strip coil, but cannot meet the winding and pressing requirements of products with special shapes such as an ellipse and a rectangle. In the winding process of the elliptical and rectangular products, the die rotates for a period, the length of the winding radius changes periodically, and the motion form of the simple straight-arm press roll cannot adapt to the rapid change of the winding radius of the rectangular die. Or, in the process of rapidly increasing the winding radius, the straight arm press roller cannot rapidly yield, so that the press roller arm is broken. Or, at the quick in-process that reduces of coiling radius, the unable follow of straight arm compression roller compresses tightly at material book foil tape surface fast, cause the cornerite that current layer foil tape formed at material book edges and corners department can not laminate completely on the surface of mould or preceding one deck foil tape, great clearance appears in cornerite department, every layer cornerite takes place to swell the phenomenon promptly, the finished product foil tape that leads to final coiling rolls up 12 and outwards loosens, make its central space grow, great space still appears behind the suit iron core piece, need artifical later stage to fill, product property ability and production efficiency have greatly been influenced.
