Automatic cutting and unwinding equipment

Abstract

The invention discloses automatic cutting and unwinding equipment. The automatic cutting and unwinding equipment comprises an unwinding mechanism, a tensioning mechanism and a cutting mechanism. The unwinding mechanism comprises at least two winding drums, wherein the winding drum completing unwinding is an old-coil winding drum, and the winding drum provided with coiled materials is a new-coil winding drum. The tensioning mechanism comprises a compression roller device and a first bypass roller device. The cutting mechanism comprises a cutter and a cutter drive device. The cutter is arranged between the compression roller device and the first bypass roller device. When the cutting mechanism performs cutting, the unwinding mechanism rotates to make the new-coil winding drum be located at the unwinding position, the coiled materials between the new-coil winding drum and the old-coil winding drum are pressed by the first bypass roller device so that the coiled materials can be tightened, and the coiled materials on the old-coil winding drum are compressed and fixed to the coiled materials of the new-coil winding drum through the compression roller device. The cutter is controlled by the cutter drive device to transversely cut the coiled materials between the first bypass roller device and the new-coil winding drum.

Description

Technical field [0001] The invention relates to the technical field of coating machine equipment, in particular to an automatic cutting and unwinding equipment. Background technique [0002] The cutting part of the existing unwinding unit uses a cutter (generally cutters are zigzag type) for cutting, and the cutting method of the cutter is to cut from top to bottom vertically, but it is affected by The influence of the coil tension on the left and right sides of the cutting part causes uneven cutting surface, and will cause a certain length of coil to be scrapped, thereby causing waste. Summary of the invention [0003] The technical problem to be solved by the present invention is to address the above-mentioned shortcomings of the prior art, and provide an automatic cutting and unwinding device, which controls the tension of the coil before cutting the coil, and changes the cutting method, which is effective To ensure the neatness of the cut surface of the coil material to a...
