[0008] 1. When the double-sided film laminating operation of the metal plate is carried out by the present utility model, the film laminating support frame and the transverse moving block are linked by a driving connecting rod, so that when the plate to be film laminated is connected to the front positioning roller, the film laminating roller and the secondary pressing roller, the moving distances of the film laminating support frames on the upper and lower sides are the same, ensuring the centering effect on the plate to be film laminated, and the forces exerted by the front positioning roller, the film laminating roller and the secondary pressing roller on the plate to be film laminated are the same, ensuring that the forces exerted when the front positioning roller, the film laminating roller and the secondary pressing roller are pressed on both sides of the plate to be film laminated are not affected by their own gravity, ensuring that the pressures on both sides of the plate to be film laminated are the same during film lamination, the film lamination effects are the same, and the double-sided film lamination effect is better.

[0009] 2. According to the plate to be film laminated with different thicknesses and different film lamination pressure requirements, the present utility model can drive the bidirectional screw to adjust the position of the sliding support table, thereby adjusting the length of the spring connecting column extending into the spring installation groove, so as to control the compression degree of the spring between the spring connecting column and the spring installation groove, and thus control the force when the film laminating roller, the front positioning roller and the secondary pressing roller press towards the plate to be film laminated. In this way, the film lamination pressure can be freely changed according to different thicknesses of the plate to be film laminated and different film lamination requirements, and the adaptability is stronger.

[0010] 3. A plurality of groups of driving connecting rods are arranged between the film laminating support frame and the transverse moving block of the present utility model, so that the plurality of groups of driving connecting rods jointly share the force when the main support frame and the transverse moving block are linked, avoiding excessive force on a single group of driving connecting rods and damage, reducing the maintenance frequency of this device, and enhancing the use stability of this device.

[0011] 4. Convex platforms are arranged on both sides of the guide roller of the present utility model to prevent the film laminating sleeve from moving left and right when it is outside the guide roller, resulting in misalignment between the film laminating and the plate to be film laminated during film lamination, and ensuring the film lamination effect and film lamination stability.
