DETAILED DESCRIPTION

[0033] The technical solution of the present application will be further described in detail below in combination with the drawings and examples. EXAMPLE

[0034] REFERENCE Figure 1 The integrated production system for super-thick mica coiled material disclosed in the present application comprises a reference mica paper output roller group 1, a plurality of mica paper hot pressing assemblies 2 and a super-thick mica coiled material storage roller 3.

[0035] REFERENCE Figure 1 The operation of the integrated production system for super-thick mica coiled material is briefly introduced as follows: the reference mica paper output by the reference mica paper output roller group 1 is hot pressed with one mica paper on the upper surface and one mica paper on the lower surface by the mica paper hot pressing assembly 2 to form a three-fold mica coiled material, the obtained three-fold mica coiled material is hot pressed with one mica paper on the upper surface and one mica paper on the lower surface by another mica paper hot pressing assembly 2 downstream to form a five-fold mica coiled material, the obtained five-fold mica coiled material is hot pressed with one mica paper on the upper surface and one mica paper on the lower surface by another mica paper hot pressing assembly 2 downstream to form a seven-fold mica coiled material, and so on. It can be known that the reference mica paper output by the reference mica paper output roller group 1 is hot pressed to form a 2n+1-fold mica coiled material by n mica paper hot pressing assemblies 2 in turn, and the obtained 2n+1-fold mica coiled material is wound on the super-thick mica coiled material storage roller 3.

[0036] In order to avoid the structure of the drawings of the integrated production system for the super-thick mica coiled material being too complex, facilitate the reader to understand the technical solution more clearly, when drawing the drawings, the number of the mica paper hot-pressing assembly 2 is selected to be 3 groups. The number of the mica paper hot-pressing assembly 2 in the integrated production system for the super-thick mica coiled material can be designed to include 3 groups, 4 groups, 5 groups, 6 groups, and 7 groups according to the thickness requirement of the mica coiled material. When the number of the mica paper hot-pressing assembly 2 exceeds 7 groups, there is a requirement for the floor height of the factory building. In theory, the higher the floor height of the factory building, the more the number of the mica paper hot-pressing assembly 2 can be designed.

[0037] Referring to Figure 1 , in order to improve the hot-pressing stability, the super-thick mica coiled material storage roller 3 is provided with an enhanced hot-pressing roller group 30 upstream. The enhanced hot-pressing roller group 30 plays a role of hot-pressing and guiding, which can ensure the hot-pressing and compounding quality of the super-thick mica coiled material. The enhanced hot-pressing roller group 30 is composed of two silicon rubber rollers. The distance between the two silicon rubber rollers is A*(2n+1) mm, A is 70 microns, and n is the number of the mica paper hot-pressing assembly 2. The roller temperature of the two silicon rubber rollers is 120-160℃, and preferably, the roller temperature of the two silicon rubber rollers is 150-160℃.

The first reference mica guide roller 12 is rotatably and fixedly connected to the floor of the second floor through a support and is located between the reference mica storage roller 11 and the first embossing roller group 13. The relative ground height of the first reference mica guide roller 12 is greater than the relative ground height of the reference mica storage roller 11 and the relative ground height of the first embossing roller group 13.

[0039] Referring to Figure 2 , the first embossing roller group 13 includes a first upper embossing roller 131 and a first lower embossing roller group 132. The distance between the first upper embossing roller 131 and the first lower embossing roller group 132 is 0.070-0.080 mm, and preferably, the distance between the first upper embossing roller 131 and the first lower embossing roller group 132 is 70 microns.

In order to avoid loss of the silicone glue, the fourth lower guide roller 226 is a silicone rubber roller, and the roller surface temperature of the silicone rubber roller is 60-80℃.

[0060] In actual operation, the integrated production system for the ultra-thick mica roll needs to ensure that the transmission speeds of the reference mica paper in the reference mica storage roller 11, the standard mica paper in the upper mica storage roller 211, and the standard mica paper in the lower mica storage roller 221 are the same, and the transmission speed is preferably 30-45 cm / min.

[0061] The embodiments of the specific implementation are the preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
