[0052] When the fourth fixed block 83 moves to a certain position, the third rack 937 meshes with the fifth gear 935, and the continued movement of the fourth fixed block 83 drives the fourth adjusting block 936 to move, the fourth adjusting block 936 drives the third rack 937 to move, the third rack 937 drives the fifth gear 935 to rotate, the fifth gear 935 drives the third rotating shaft 933 to rotate, the third rotating shaft 933 drives the fourth gear 934 to rotate, the fourth gear 934 drives the second rack 932 to move, the second rack 932 drives the third adjusting block 931 to move, and the third adjusting block 931 drives the lifting block 91 to move, so that the lifting block 91 can lift the bottom paper.

[0053] The implementation principle of the vapor phase anti-rust paper coating device of the embodiment of the present application is as follows: after the base paper on the winding shaft is wound out, it will bypass the conveying roller 12 on the main body 11, and the first limiting roller 23 and the feeding roller 43 respectively abut on both sides of the base paper, and the coating roller 22 and the second limiting roller 24 also abut on the base paper; and the base paper passes between the second clamping block 84 and the fourth fixing block 83. The base paper moving out of the main body 11 directly enters the oven for drying.

[0054] When the reel with the base paper needs to be replaced and the base paper is unwound from the main body 11, the power member 335 is started to make the tensioning roller 32 tension the base paper, so that the coating roller 22 can better coat the vapor corrosion inhibitor on the base paper.

[0055] When all the bottom paper on the winding shaft is wound out and part of the bottom paper has not entered the main body 11, the fourth motor 581 and the rotating motor are started first to move the two first adjustment blocks 56 on the second fixed block 55 to a position parallel to the bottom paper; then the first motor 610 is started to move the two first clamping blocks 57 in a direction close to the bottom paper so that the bottom paper is located between the two first clamping blocks 57; then the fifth motor 591 is started to clamp the bottom paper with the two first clamping blocks 57; and then the fourth motor 581 is started to move the two first clamping blocks 57 while clamping the bottom paper so that the bottom paper between the first limiting roller 23 and the fourth conveying roller 12 is still in a tensioned state, thereby reducing the phenomenon of wrinkles in the bottom paper. When the lifting block 52 moves to the upper end of the first fixed block 51, the first clamping block 57 is first restored to its original position, and there is a moving distance between the first clamping block 57 and the bottom paper; then the lifting block 52 drives the second fixed block 55 to rotate through the extension block 54, so that the second fixed block 55 rotates to one side of the first fixed block 51 without affecting the movement of the other second fixed block 55. The two second fixed blocks 55 on the first fixed block 51 move alternately, and the first clamping blocks 57 on the two second fixed blocks 55 can clamp the bottom paper, so that the tension of the bottom paper can be maintained.

[0056] When no base paper bypasses the fourth conveying roller 12, and the end of the base paper is clamped by the two first clamping blocks 57 on the second fixed block 55 and moves to the vicinity of the first limiting roller 23, the seventh motor 865 is started to clamp the second clamping block 84 and the fourth fixed block 83 to the base paper; then the sixth motor 851 is started, and the slider 82 drives the fourth fixed block 83 to move toward the coating roller 22; the second clamping block 84 and the fourth fixed block 83 clamp the base paper, so that the coating roller 22 can coat the tensioned base paper with a vapor corrosion inhibitor. When the second clamping block 84 is about to approach the accommodating block 21, the fourth adjusting block 936 on the fourth fixed block 83 causes the third rack 937 to mesh with the gear, so that the lifting block 91 contacts the bottom paper and lifts the bottom paper; after the lifting block 91 lifts the bottom paper a certain distance, the seventh motor 865 is started so that the second clamping block 84 and the fourth fixed block 83 no longer clamp the bottom paper, and the sixth motor 851 is started so that the fourth fixed block 83 returns to a position close to the first limiting roller 23.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
