Problems solved by technology

[0003] At present, the mica tape splitting and cutting equipment mostly adopts manual or intelligent control of unwinding and winding tension to adjust and control the mica tape winding tightness. Because the thickness of the mica tape is still uneven, when the mica tape is required to be cut with a narrower width When tape, the requirements for tension control are higher, otherwise the ultra-narrow mica tape after cutting will collapse or cross the plate due to uneven tightness, the yield rate is extremely low, and even part of the width cannot be cut and split.

Embodiment 1

[0026] Embodiment 1 A kind of 20mm wide single-volume overlapping double-head phlogopite single-sided tape, its manufacturing method comprises the following steps:

[0027] (1) Blank tape production: (1-1) unwind the phlogopite paper and glass fiber cloth respectively through the automatic tension controller, (1-2) compound the glass fiber cloth with glue and mica paper, (1-3) mica After the paper is infiltrated, it enters the oven for drying, curing, and winding to obtain the mica tape blank;

[0028] (2) Blank tape slitting and splitting: cut the 1000mm wide mica tape base roll into 50 mica tape reels with a width of 20mm;

[0029] (3) Winding: Install two 20mm-wide mica tape reels on the two unwinding ends. After passing through the automatic constant tension system and positioning with multiple positioning wheels, the two mica tape heads are neatly overlapped. The rewinding arm at the end of the reel moves to reel into a mica tape;

[0030] (4) Use silicone pressure-sens...

Embodiment 2

[0033] Embodiment 2 A 4mm wide single disc side-by-side double-headed phlogopite three-in-one belt, its manufacturing method comprises the following steps:

[0034] (1) Blank tape production: (1-1) unwind the phlogopite paper and glass fiber cloth respectively through the automatic tension controller, (1-2) compound the glass fiber cloth with glue and mica paper, (1-3) mica After the paper is infiltrated, it enters the oven to dry and solidify, and then it is rewound after compounding with the film to obtain the mica tape blank;

[0035] (2) Blank tape slitting: After the 1,000mm wide kilometer mica tape blank master roll is opened four times, after passing through the automatic deviation correction constant tension system again, it is cut into mica tape strips by a precision slitting machine, and passed through the collection The winding device is wound on a set of coil cores with a width of 8mm to obtain a 4mm wide single-disk side-by-side double-headed phlogopite three-in-o...

Abstract

The invention relates to the field of manufacturing of electrical insulating materials, and provides a manufacturing method of a double-end mica tape, which comprises the following steps: (1) unwinding mica paper and a reinforcing material; (2) gluing the reinforcing material and compounding with mica paper; (3) drying, curing and rolling to obtain a mica tape blank tape; and (4) slitting the micatape blank tape mother roll into a required width, and rolling to obtain the double-end mica tape roll. The method provided by the invention is a production method of a product for realizing multi-layer wrapping on a single wrapping head of a paper wrapping machine, the length of the product can reach a ten thousand meter level, the problems that a 3-5mm ultra-narrow mica tape is easy to collapseand cross over are solved, and the requirements on a mica tape group in the production and application processes are met.

Description

technical field [0001] The invention relates to a manufacturing method of an electrical insulating material, in particular to a manufacturing method of a double-headed mica tape. Background technique [0002] The mica tape for fire-resistant safety cables is based on heat-resistant and insulating mica paper, with electronic-grade alkali-free glass fiber cloth (or film, etc.) The strip-shaped insulating material formed by wrapping the mica tape on the core wire by the wrapping machine makes the finished cable keep running safely for a certain period of time under the condition of flame burning. [0003] At present, most mica tape splitting and cutting equipment adopts manual or intelligent control of unwinding and winding tension to adjust and control the mica tape winding tightness. Since the thickness of the mica tape still exists inhomogeneity, when the mica tape is required to be cut with a narrower width When belting, the requirements for tension control are higher, oth...
