Detailed Description

In order that the objects, aspects and advantages of the utility model will become more apparent, the utility model will be described by way of example only, and in connection with the accompanying drawings. It is to be understood that such description is merely illustrative and not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

It should be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and/or processing steps closely related to the scheme according to the present invention are shown in the drawings, and other details not so relevant to the present invention are omitted.

Referring to fig. 1 to 4, the following technical solutions are adopted in the present embodiment: the mica tape winding machine comprises a winding seat 1 and a mica tape body 2; the mica tape body 2 is densely wound on the outer side of the winding seat 1; the mica tape body 2 comprises a glass fiber reinforcing layer 3, a Teflon line 4, a first mica paper board 5, a second mica paper board 6 and a heat-resistant self-adhesive layer 7; the inside of glass fiber reinforcement layer 3 inlay and have teflon line 4, and the lower extreme of glass fiber reinforcement layer 3 is connected with first mica cardboard 5, the lower extreme of first mica cardboard 5 is connected with second mica cardboard 6, the lower extreme spraying of second mica cardboard 6 has heat-resisting self-adhesive layer 7.

The glass fiber reinforced layer 3, the first mica paper board 5 and the second mica paper board 6 are connected by taking amino borane-epoxy resin as an adhesive; two sides of the Teflon line 4 are provided with outward-expanding branches 8, so that the Teflon line 4 and the glass fiber reinforced layer 3 keep a stable connection structure; a polyester film is arranged on the surface of the heat-resistant self-adhesive layer 7; the Teflon lines 4 are distributed at the three points of the glass fiber reinforced layer 3.

The working principle of the specific implementation mode is as follows: when the high-strength electromagnetic wire is wrapped and wound, firstly, the film on the surface of the heat-resistant self-adhesive layer 7 is uncovered, and the high-strength electromagnetic wire is wrapped by extending forwards; in the wrapping process, the heat-resistant self-adhesive layer 7 is bonded on the outer surface of the high-strength electromagnetic wire, and the Teflon wire 4 is wound and wrapped on the surface layer of the mica tape to form a bundling wrapping layer; the mica tape can be kept to be tightly attached, namely reinforcing wire harnesses are wound on the surface layer; the method avoids the high-strength electromagnetic wire from being locally degummed under the high-temperature, magnetic field and vibration environment, so as to cause the mica tape to be loose and broken; in addition, the glass fiber reinforced layer 3 increases the strength of the first mica paper board 5 and the second mica paper board 6, so that the first mica paper board 5 and the second mica paper board 6 are not easy to break; the Teflon thread 4 has double effects of reinforcement and shaping.
