[0045] Embodiment 2:
[0046] Please see attached Figure 1 - Attachment Figure 8 The embodiment of the present invention provides a method for precision coating of impregnated paper, comprising the following steps:
[0047] S1: First, the coated paper to be coated is transported to the middle of the upper end of the bottom frame 1 through the transmission mechanism, so that the paper to be coated is located on the upper part of several equidistant array pressure detection devices 105. At this time, the rotating lower pressure plate 803 is in a 190° vertical state with the bottom frame.

[0048] S2: Then the first motor 401 drives the threaded rod 402 to rotate, so that the coating device 501 moves to the right. When the coating head 502 moves to the leftmost end of the paper to be coated, the coating liquid containing nano-scale magnetic particles is sprayed on the paper to be coated, and the spraying is performed from left to right.

[0049] S3: After coating one side of the paper to be coated, the moving unit 4 is located on the right side, and the coating unit 5, the electromagnetic interference unit 6 and the electromagnetic adsorption unit 7 are moved from the right side to the left side through the moving unit 4, and the first mounting frame 602 and the second mounting frame 702 are pushed downward by the first telescopic rod 601 and the second telescopic rod 701, so that the control device 603 and the adsorption device 703 are moved to the upper part of the coated paper, and then the control device 603 and the adsorption device 703 are moved from the right side to the left side through the moving unit 4;
[0050] S4: During the movement, the control device 603 controls the electromagnetic coil 604 to generate a dynamic opposing magnetic field. The dynamic opposing magnetic field causes the nano-scale magnetic particles contained in the coating liquid to move with it, thereby affecting the adhesion and flow of the coating to accurately control the coating thickness. After the adsorption device 703 adsorbs the magnetic particles through the adsorption holes 704, it is transported to the container through the transport pipeline for recovery;
[0051] S5: Finally, after the nano-scale magnetic particles in the coating liquid on the paper are absorbed, tiny gaps are left in the coating to form a uniform microporous structure, and the uniformity of the coating is detected by the pressure detection device 105.
[0052] By using spraying, electromagnetic interference and electromagnetic adsorption technologies, the adaptability and control accuracy of the coating system are enhanced, and precise coating of multiple functional layers is achieved to meet the diverse needs of high-performance impregnated paper.
