Description

A mica paper pressing device Technical Field

[0001] This utility model relates to the technical field of mica paper pressing device, and particularly to a mica paper pressing device. Background Technology

[0002] Mica paper, also known as fire-resistant mica paper, is made by a mica paper machine. It is a high-performance mica insulation product with excellent high-temperature resistance and flame retardancy. According to its application, it can be divided into: mica paper for motors and mica paper for cables. According to its structure, it can be divided into: double-sided tape, single-sided tape, three-in-one tape, double-film tape, single-film tape, etc. Single-sided tape uses mica paper as the main material, with fiberglass cloth adhered to one side using adhesive, then rolled up and cut into tapes of different specifications. However, existing pressing devices, when pressing glued and cloth-attached mica paper, simply press two pieces of mica paper together using a first and second pressing roller, and then roll them up using a winding device. It has been found that existing pressing devices for mica paper processing cannot change the pressing force on the mica paper during pressing, resulting in poor practicality and easy curling of the mica paper edges.

[0004] Preferably, it also includes a bracket, on which a support plate is provided, and the pressing edge assembly is disposed above the support plate.

[0005] Preferably, the fine-tuning component includes a mounting groove disposed on the bracket, a first bearing seat and a second bearing seat disposed on the mounting groove, a compression spring disposed between the first bearing seat and the second bearing seat, and an adjusting screw disposed above the first bearing seat, wherein the first pressing roller and the second pressing roller are respectively mounted on the first bearing seat and the second bearing seat.
