Insulation paper cutting machine

Technical Field

The utility model relates to the technical field of paper cutting machines, and more specifically, to an insulating paper cutting machine.

Background Art

Insulating paper is a kind of paper with insulating properties. It is usually made of plant fibers, mineral fibers, synthetic fibers or a mixture of these fibers. Through a specific process, these fibers are deposited on a papermaking machine to form a thin sheet of material. Insulating paper has good insulating properties and mechanical strength, so it is widely used in the manufacture of electrical equipment such as motors, cables, capacitors and transformers. It is also used in the production of insulating materials such as laminates, composites and prepregs, which have high tear strength and low elongation. The traditional way of cutting insulating paper is to manually cut the paper with a handheld cutter and a steel ruler. This operation method has low efficiency and high labor intensity.

The pressure pad is installed on the operating table, the tool holder is arranged across the pressure pad and the operating table, and the cutting assembly is installed on the tool holder. The operating table includes a platform, a main lug, a main column, a secondary lug, a secondary column and a cutting groove. There are a pair of main lugs on both sides of the front half of the platform, a main column on the main lug, a pressure pad is installed on the main column, a pair of secondary lugs in front of the main lug, a secondary column on the secondary lug, and a tool holder is installed on the secondary column. The pressure pad includes a crossbeam, an ear piece, a main spring, a pad and a baffle. There are a pair of ear pieces at both ends of the crossbeam, and the ear pieces are installed on the main column. The tool holder includes a follower beam, a through groove, a frame ring, a side column, a sleeve, a chuck, a secondary spring, a nut and a front lug. The cutting assembly includes a screw, a bevel gear, a driving gear, a hexagonal head, a slider, a limit block and a cutter. The screw is installed on the frame ring. This technical solution is used for cutting operations of transformer coil insulating cardboard. It has good positioning and clamping capabilities, but it requires the use of electric tools to complete the cardboard cutting.
