[0003] At present, the flexible mica composite is formed by hot pressing of multiple flexible mica papers. The existing continuous production equipment for the flexible mica composite has the following composite mode: two standard mica tapes are unwound, the standard mica tapes are hot-pressed by a hot-pressing roller to form a double-mica paper composite, another standard mica tape is unwound, and the double-mica paper composite and the other standard mica tape are hot-pressed by the hot-pressing roller to form a triple-mica paper composite. In this way, after n hot-pressing procedures, the flexible mica composite with a specified thickness can be obtained.

[0004] The inventor finds that in the production process of the large-width flexible mica composite, the mica paper is prone to wrinkles due to the large width of the flexible mica paper, which causes the problem of wrinkles in the finished flexible mica composite after hot pressing, affects the quality and yield of the super-thick flexible mica composite, and also increases the production cost of the super-thick flexible mica composite. In order to solve the above-mentioned problems existing in the prior art, the application provides a production equipment for wrinkle-free super-thick flexible composite material.

As the push rod of the first air cylinder 106 drives the left flat brush plate 105 to move from the middle part of the connecting piece 102 to the left end of the connecting piece 102, the lower end of the left flat brush plate 105 abuts against the upper surface of the standard mica paper or n-fold mica paper composite, which can effectively unfold the standard mica paper or n-fold mica paper composite, eliminate the generation of wrinkles during the hot-pressing process, and improve the quality and yield of the finished product of the ultra-thick flexible mica composite material.

[0061] Referring to Figure 1 and Figure 4The bottom of the second adjusting rod 104 is provided with a T-shaped sliding groove along the length direction of the second adjusting rod 104. The bottom of the second adjusting rod 104 is slidingly connected with the right flat brush plate 107. The upper part of the right flat brush plate 107 is integrally formed with a T-shaped sliding block. The T-shaped sliding block of the right flat brush plate 107 is embedded in the T-shaped sliding groove of the bottom of the second adjusting rod 104, so that the right flat brush plate 107 is slidingly connected with the second adjusting rod 104. The bracket 101 is fixedly connected with the second cylinder 108 on the right side. The push rod of the second cylinder 108 is connected with the center part of the right flat brush plate 107. That is, the central axis of the push rod of the second cylinder 108 is perpendicular to the side surface of the bracket 101 and also perpendicular to the side surface of the right flat brush plate 107. In order to improve the flattening effect, the position relationship between the central axis of the push rod of the second cylinder 108 and the right flat brush plate 107 is adjusted. The line-plane angle formed by the central axis of the push rod of the second cylinder 108 and the plane of the right flat brush plate 107 is 82-88°, and the push rod of the second cylinder 108 is inclined upward.

[0062] The right flat brush plate 107 is in an initial state. The right flat brush plate 107 is located in the middle of the connecting piece 102, and the distance between the lower end of the right flat brush plate 107 and the lower surface of the standard mica paper or m-folded mica paper composite is 0. As the push rod of the second cylinder 108 drives the right flat brush plate 107 to move from the middle of the connecting piece 102 to the right end of the connecting piece 102, the lower end of the right flat brush plate 107 abuts against the lower surface of the standard mica paper or m-folded mica paper composite, which can effectively expand the standard mica paper or m-folded mica paper composite, eliminate the generation of wrinkles during the hot-pressing process, and improve the quality and yield of the finished product of the ultra-thick flexible mica composite material.

[0063] The difference between the embodiment 2 and the embodiment 1 is that Figure 5 The line-plane angle formed by the central axis of the push rod of the first cylinder 106 and the plane of the left flat brush plate 105 is 90°. The connecting piece 102 is fixedly connected with the third cylinder 1023. The push rod of the third cylinder 1023 is hingedly connected to the center part of the upper surface of the first adjusting rod 103.

[0064] The difference between the embodiment 2 and the embodiment 1 is that Figure 5 The distance between the lower end of the left flat brush plate 105 and the upper surface of the standard mica paper or n-folded mica paper composite is adjusted by the third cylinder 1023. As the push rod of the first cylinder 106 drives the left flat brush plate 105 to move from the middle of the connecting piece 102 to the left end of the connecting piece 102, the third cylinder 1023 slowly pushes the first adjusting rod 103 to rotate downward, so that the lower end of the left flat brush plate 105 abuts against the upper surface of the standard mica paper or n-folded mica paper composite, which can effectively expand the standard mica paper or n-folded mica paper composite, eliminate the generation of wrinkles during the hot-pressing process, and improve the quality and yield of the finished product of the ultra-thick flexible mica composite material.

[0065] The difference between the embodiment 2 and the embodiment 1 is that Figure 5, the line surface angle formed by the middle axis of the push rod of the second cylinder 108 and the plane of the right flat brush plate 107 is 90°, the connecting piece 102 is fixedly connected with a fourth cylinder 1024, and the push rod of the fourth cylinder 1024 is hingedly connected to the middle part of the upper surface of the second adjusting rod 104.

[0066] With reference to Figure 5 The fourth cylinder 1024 adjusts the distance between the lower end of the right flat brush plate 107 and the upper surface of the standard mica paper or m-folded mica paper complex, and as the push rod of the second cylinder 108 drives the right flat brush plate 107 to move from the middle part of the connecting piece 102 to the right end of the connecting piece 102, the fourth cylinder 1024 slowly pushes the second adjusting rod 104 to rotate downward, so that the lower end of the right flat brush plate 107 abuts against the lower surface of the standard mica paper or m-folded mica paper complex, effectively expands the standard mica paper or m-folded mica paper complex, eliminates the generation of wrinkles in the hot-pressing process, and improves the quality and yield of the finished product of the ultra-thick flexible mica composite material.
