[0002] Insulation paper is a general term for electrical insulation paper, which is used as insulation material for various electrical equipment such as cables and coils. It has good insulation performance and mechanical strength. Insulation paper is mainly made of a mixture of natural wood pulp, paper pulp and special additives. It is usually soft, natural and resistant to arc burning. In addition, insulation paper also has good heat resistance, anti-aging performance and moisture resistance, which can ensure the normal operation of electrical equipment in harsh environments.

[0003] At present, the cutting equipment on the market does not have a device to fix the insulating paper when cutting it. The insulating paper is generally in the form of a cylindrical roll when it leaves the factory. Therefore, in order to make the insulating paper meet the different usage requirements of motors of different specifications, the insulating paper needs to be cut manually or by a cutting machine. During the cutting process of the insulating paper, due to its inherent flexibility, curling or displacement is prone to occur during the cutting process. This curling or displacement will not only affect the cutting accuracy, but may also pose a threat to the safety of the operator. Utility Model Content
