Description

Technical Field

[0001] The utility model belongs to the technical field of insulating composite film slitting processing devices, and in particular relates to a slitting device used for insulating composite film processing. Background Art

[0002] Insulating composite film, also known as insulating film, is made of a variety of insulating materials such as polyimide and polytetrafluoroethylene (PTFE), and other insulating materials such as aluminum oxide, silicon nitride, mica, silicon oxide, etc. Insulating film is widely used in the fields of electronics, electrical engineering, etc. Plastic insulating film and mica tape used for insulating film composite are generally cut by slitting machines. Slitting machines are mainly used for: slitting non-woven fabrics, mica tapes, paper, insulating materials and various composite film materials. Slitting machine types mainly include longitudinal slitting machines, cross-cutting machines, circular knife slitting machines, flat knife slitting machines and guillotine slitting machines. The cross-cutting device of the cross-cutting machine is mainly used to cut the material that has been cut into a narrow width horizontally to generate a fixed length of sheet or small roll. The working principle of the cross-cutting device is mainly to drive the cutting tool through a motor or cylinder or hydraulic cylinder and other equipment to move the tool horizontally and vertically, thereby completing the cutting of the material;

[0003] A cross-cutting device is used to cut the insulating film material and cut it into the same size or length. When a straight knife is used for slitting for a long time, problems such as improper tool installation, knife surface wear, cutting edge bluntness, dirt or burrs on the knife surface may occur, and the tool needs to be disassembled for processing. The traditional tool assembly process is relatively cumbersome, and is generally fixed by multiple screws. During installation, the tool needs to be fixed first and the position adjusted accurately. The installation process is time-consuming and labor-intensive, and it is inconvenient to disassemble and clean the wear problem, and it is not conducive to replacing the tool.

For this reason, the present application proposes a slitting device for insulating composite film processing. Utility Model Content
