A coil feeding and coil changing mechanism

Abstract

The invention discloses a feeding and coil replacing mechanism of coiled materials. The feeding and coil replacing mechanism comprises a frame which is provided with a coil replacing positioning roller and a coil replacing swing roller; two ends of the coil replacing swing roller are in rotating connection with swing arms respectively; the swing arms are connected with the frame through hinges; one side of the frame is hinged to swing arm driving cylinders; one ends of piston rods are hinged to the swing arms; the other ends of the piston rods are matched with the swing arm driving cylinders; pressing rollers are arranged on one sides of the coil replacing positioning roller and the coil replacing swing roller respectively; two end portions of the pressing rollers are hinged to one ends of swing rods; the middles of the swing rods are hinged to the frame and the swing arms; the other ends of the swing rods are hinged to one ends of the piston rods; the other ends of the piston rods are matched with pressing roller driving cylinders; the pressing roller driving cylinders are hinged to the other side of the frame. According to the feeding and coil replacing mechanism of the coiled materials, the coil replacing operation is safe and reliable, the quality of connection between the coiled materials is good, the operation is simple and convenient, the structure is simple, the maintenance is convenient, and the problem of the continuous unreeling feeding of the coiled materials is well solved.

A layer of nylon net is added between two layers of plastic films through the above mechanism, and the...

AI Technical Summary

Problems solved by technology

In the existing advertising cloth production equipment, the coil unwinding and roll changing mechanisms are all operated on the roll changing support. In this way, since the coil has been unwinding, it is difficult to achieve uninterrupted connection with the new roll. Since the width of the advertising cloth is generally more than 4 meters wide, it increases the difficulty of connecting the rolls.
