[0061] The lifting limit member 353 is designed. When the lower die head needs to adjust the coating height, the height of the lower die head is restricted by the lifting limit member 353;

[0062] By designing the rotation limit member 22 and the lifting limit member 353, the present application can adapt to more working scenarios and modes.

[0063] A rotation part for driving the upper coating die head 2 to rotate reciprocally and a lifting part for driving the lower coating die head 3 to lift and lower reciprocally are installed on the back of the frame body 1.

[0064] The rotation part includes:

[0065] A rotation connection frame 23, which is installed on the back of the frame body 1;
