Problems solved by technology

When the defective film roll is slitting on the slitting machine, under the action of tension and stress, the defective part often breaks the film and winds up on the roller, so that it is necessary to stop the machine to clean the winding film and reconnect the film. In order to continue cutting, in severe cases, it is even necessary to cut off the film with adhesion and gap
In this way, not only is the finished product wasted and the yield rate is reduced, but also the connection of the product is a waste of time, which seriously affects the production efficiency

Abstract

The invention discloses an edge cutting device for a film roll. The edge cutting device for the film roll comprises an electromagnetic base, a variable-frequency motor, a spiral lifting device, an edge cutter and an edge cutter adjusting rod, wherein the spiral lifting device is installed on the electromagnetic base and is controlled by the variable-frequency motor, the edge cutter adjusting rod is movably installed on the spiral lifting device, and the edge cutter is movably installed on the edge cutter adjusting rod. The edge cutting device for the film roll is used for pre-cutting the edge of the film roll, the position, the height and the angle can be adjusted flexibly, and defected film roll edges can be cut off rapidly and efficiently.

Description

technical field [0001] The invention relates to a film cutting device, in particular to a film roll trimming device. Background technique [0002] The preparation of film materials involves steps such as melting, extrusion, stretching, winding, and cutting. In the winding step, if the tension control process parameters of the winding system are unreasonable or the equipment is abnormal, the edge of the film roll will be stuck. , Burrs, gaps and other defects. When the defective film roll is slitting on the slitting machine, under the action of tension and stress, the defective part often breaks the film and winds up on the roller, so that it is necessary to stop the machine to clean the winding film and reconnect the film. In order to continue cutting, in serious cases, it is even necessary to cut off the film with adhesion and gap. In this way, not only the finished products are wasted and the rate of finished products is reduced, but also the connecting time of the produ...
